The technical FIELD

[0001] the Examples and embodiments of the present invention that it is not limited to, generally relate to wireless communication systems, methods, devices and computer programs and, more specifically, to methods of activation/deactivation of component carrier system that uses carrier aggregation.

BACKGROUND of INVENTION

[0002] this section provides information about the prerequisites for the establishment or the context of the present invention, which is set forth in the claims. The description may contain concepts that can be implemented, but not necessarily been reviewed or implemented before. Thus, unless otherwise stated, this section does not describe the state of the art prior to the description and the claims contained in the application, and not assume that the questions included in this section belong to the prior art.

[0003] the Following are abbreviations that may appear in the following description and/or the accompanying drawings.

[0004] In the framework of the communication system, known as advanced network UTRAN (E-UTRAN, also referred to as UTRAN-LTE, E-UTRA or 3.9G), completed the development of the LTE system version 8, work on standardization of the LTE system version 9, and at the present time within 3GPP is developing a system LTE version 10. In LTE as the technology of the access downlink OFDMA is used, and in the ascending line SC-FDMA, and it is assumed that these access technologies will be applied in the LTE system version 10.

[0005] figure 1 is reproduced figs document 3GPP TS 36.300 V8.6.0 (2008-09), which shows the overall system architecture of E-UTRAN. Part of the EUTRAN system includes nodes eNB providing the end of the Protocol E-UTRA for the user plane and control plane (RRC) towards the UE. The eNB nodes are interconnected with each other through the x2 interface. In addition, the nodes eNB via the S1 interface is connected to an EPC, more specifically to the MME and to the serving gateway. The S1 interface supports a type of "many to many" between objects MME/serving gateway and the eNB nodes.

[0006] In this description are of special interest subsequent versions of the 3GPP LTE is designed to support future advanced systems IMT (IMT-Advanced), hereinafter referred to simply LTE-A (LTE-Advanced). System LTE-A is designed for expansion and optimization of radio access technologies 3GPP LTE version 8 to provide higher data rates at very low cost. Most likely, LTE-A will be part of the LTE system version 10. It is expected that within the LTE-A will apply a combination of optimization methods in local and global network to meet the requirements of ITU-R on IMT-Advanced systems, with support for backward compatibility with LTE release 8. The main subject of ongoing debate, among other things, is to expand the bandwidth beyond 20 MHz.

[0007] the Expansion of bandwidth in the system LT-Advanced (for example, beyond 20 MHz, but the aggregation of larger or smaller component carrier (CA, carrier aggregation), according to which a few are compatible with the system version 8 load-bearing aggregated together to form the bandwidth of the system. An example of this process is shown in figv, which shows the 5 aggregated component carriers (CC, component carrier that is compatible with the system version 8 and forming a single wide bandwidth system LTE-Advanced. The purpose of the aggregation of individual component carrier, for example, compatible with the system version 8 with a bandwidth of 20 MHz, is that each existing terminal version 8 could receive and/or transmit data in one component carrier, while future terminals LTE-Advanced could potentially receive/transmit data simultaneously by multiple component carrier that provides support for a broad band of frequencies. On FIGU shows a specific circuit system LTE-Advanced, which, however, gives an idea about the General concept of SA, regardless of size SS; for example, a shorter frequency fragments, such as SS 10 MHz, can be aggregated to obtain the bandwidth of 20 MHz, and the SS can form a range, a larger 20 MHz. In the LTE system version 8 allowed bandwidth of 1.4 MHz, 5 MHz and 10 MHz, and 20 MHz, so any ecigpros can have the size of the SS.

[0008] In the LTE system version 8 channel PDCCH may be used only to indicate PDSCH/PUSCH transmitted in its own SS DL or in the steam MOP UL. Devices UE version 10 you can use the node eNB and the UE device several hundred for communication in multiple frequency ranges (several SS). In order to more simple way to use this function, you need to find a solution how to potentially activate and deactivate the application of SA.

[0009] currently already developed the concept of cross-planning SS, which allows you to use the information on the allocation of resources transferred (for example, PDCCH) node eNB in one of the SS (SOTE), planning/allocation radioresource in another SS (SOTE). In this procedure, cross-submission planned SS using a 3-bit field indicating the carrier (CIF, Carrier Indication Field that is added to the data format of the DCI and indicates how SS are allocated resources. The transmission of the PDCCH based on the stew, so when you have many SS is determined that the channel PDCCH should be transmitted in a cell corresponding to a particular SS. When it is not determined whether to vary the value of the CIF for UL and DL.

[0010] it is Also assumed that the resources of the UE 10 may not necessarily planned within all five SS, shown as p is of iMER on FIGU (or all SS, the components of the full frequency band), and can take a subset of these frequencies for which the configured UE through RRC signaling. Due to this UE to search for its PDCCH should not perform power-intensive procedure of blind detection of each possible SS within the whole frequency band. On the basis of the configured UE set SS (by SA UE) should be more dynamic than the RRC signaling, the approach to negotiation between the eNB and the UE of information about the specific active SS, and, thus, should be the mechanism for activation and deactivation hundred/individual SS belonging to the set CC configured for the UE. The RRC signaling is not considered as an effective tool for this task, since the quasi-static nature of this procedure leads to long delays, especially peculiar for her delays and temporal uncertainties inherent in HARQ and ARQ at activation and/or deactivation of any of the SS.

[0011] the Relevant proposals in this regard were presented in 3GPP in the following documents: R2-096502 (3GPP TSG-RAN WG2 #68 "Activate and deactivate a carrier (the" Carrier activation and de-activation"), CATT, 9-13 November 2009); R2-096997 (3GPP TSG-RAN WG2 #68 "discussion of the configuration of the SS" ("Discussions of CC configuration"), Fujitsu, 9-13 November 2009); R2-096752 (3GPP TSG-RAN WG2 #68 "Activation and deactives the function of the component carrier" ("Activation and de-activation of component carriers"), Eriksson and ST-Eriksson, 9-13 November 2009) and R2-095808 (3GPP TSG-RAN WG2 #67-bis Activate and deactivate the component carrier" ("Activation and de-activation of component carriers"), Eriksson and ST-Eriksson, 12-16 October 2009). In addition, the UTRAN network version 8 defined functional diagram HSPDA dual hundredth (dual cell-HSPDA), which partially includes the activation/deactivate based on a sequence of HS-SCCH secondary carrier downlink, as well as functional diagram HSUPA dual-hundredth (dual cell-HSUPA) defined in UTRAN version 9. See, for example, 3GPP TS 25.212 and 25.214.

DETAILED DESCRIPTION</>

[0030] As noted above, for activation and deactivation of individual SS to the UE requires a mechanism that differ somewhat from the RRC signaling, it is quite fast and reliable in regard to the process of "simultaneous" taking the eNB and UE decisions about whether and at what time there are specific honeycomb carrier in SS, is available for use in the SA process.

[0031] In accordance with an exemplary embodiment of the present invention from the eNB in the affected UE is transmitted sequence PDCCH", which combines the indication of activation of the SS indicating the code word or preamble to be used to access re-enabled SS. For example, the indication of activation of the SS can be a 1-bit field in the format 1A DCI (see, for example, 3GPP TS 36.212 v8.7.0, section 5.3.3.1.3), modified to accommodate this indication of activation of the SS. For example, without limiting the present invention, this new DCI format may be defined as a format 1A DCI, identical in length to the format 1A DCI used in the prior art, but with a specific bit fields, which are overridden by the way, described in detail below in the example. More specifically, in the embodiment of the present invention, one or more bits that are set to zero in the format 1A indicator DCI known for the level of technology (resulting from their use is not tolerated useful information, and they ignored UE in the prior art), become active in the example implementation of format 1A DCI according to the ideas of this invention and transfer information about what specifically the SS (or what SS) is activated. In other words, in the exemplary embodiment of the present invention, this one bit (or several bits) indicate a couple of SS UL/DL, which should be activated. If for indicating the activated SS uses multiple bits, these bits can be selected bitmap index corresponding to one of the SS or the SS group, subject to activation.

[0032] On figa shows the format 1A sequence PDCCH prior art defined for the LTE version 8 (see, for example, 3GPP TS 36.212 version 8.7.0 [2009-05], Chapter 5.3.3.1.3). In this format there is a bit that specifies which uses the DCI format 0 or 1A. In this case, you specify the format 1A. In addition, there is a localized/distributed bits and a bit string of the destination of the resource block, all bits in which format 1A is set to 1. The final section of the fragment sequence PDCCH format 1A, as shown in the drawing, consists of three bits, nullable in all cases, format 1A. These zero bits do not carry any useful information for the UE and are ignored by this equipment. They are designed to keep to the actual length of a string in the format 1A. The number of unused bits vary slightly depending on whether the configuration mode TDD or FDD mode.

[0033] On figv in accordance with the ideas of the invention shows an example of format 1A indicator DCI in accordance with the ideas of the present invention, illustrating only the concept of the invention, but not limiting it. On FIGU shows the sequence PDCCH, which is more generally referred to simply control information downlink. On FIGU shows a particular implementation of format 1A DCI based on sequence PDCCH format 1A DCI shown in figa, however, other embodiments of the present invention may also differ in other respects. As a traditional sequence PDCCH shown in figa, and an example implementation of format 1A shown in figv are identified by a string resource block assignment (RBA resource block assignment), all bits which are set to '1'. The inventors have found that one or more unused bits in this traditional sequence PDCCH format 1A shown in figa can be used in example implementations of format 1A sequence PDCCH to display the SS.

[0034] More specifically, figv shows the control indicator downlink/posledovatelno the ü 200 PDCCH, which contains the following fragments. The sequence contains the first selector 202 format, which tells the UE, whether this DCI format 0 or format 1A. Next is localized/distributed segment flag 204, segment 206 to the destination resource block (all bits which, for example, set to 1 for formats 1A and 1A DCI) and the first bit sequence or bit line 210, which contains the segment index 208 of the preamble and the index 209 mask primary RACH (PRACH). The first bit line or bit sequence 210 format 1A shown in figv, gives an indication for the selected preamble (or, more generally, the code word access)used in the procedure random access enabled SS. For example, the first bit sequence 210 is an index for a codebook stored in the local memory eNB and UE, and the UE provides a dedicated preamble, which is used in the procedure of access to the RACH, shown in figure 3 and 4. The second bit line or bit sequence 212 in this embodiment contains, as stated above, one or more bits that are not used in the prior art, but, according to the present invention, indicating activated SS. In a specific embodiment, the present izobreteny is, shown in figv, the second bit sequence is used to perform two functions: it selects formats 1A and 1A DCI, and, as noted above, contains information about the mapping of the SS. In that case, if the format 1A shown in figv, is the same length as traditional format 1A shown in figa, and the second bit sequence 212 is an input index in the bitmap that specifies activated SS or more of the SS, it is preferable to avoid the use of recording bitmap specified with zeroes, because the presence of nonzero bits in the second bit sequence in this embodiment can indicate the difference between format 1A sequence PDCCH shown in figv, and traditional format 1A shown in figa.

[0035] the Second bit sequence 212 may include one or more bits used for indicating and displaying at least one activated SS. In the exemplary embodiment of the present invention in the second bit sequence 212 there is only one bit that specifies information about the activation of the SS in the implementation of format 1A, and with this the only bit activates many of the SS. Because the format 1A DCI 200 second bit line 212 contains several bits, the remaining bits, if they imets is, except for the above one bit can be reset to zero in all variants of format 1A DCI and, thus, ignored UE, as in the case when all of this section consists of zeros and ignored by the UE, as it indicates that the DCI 200 is transmitted in the format 1A.

[0036] it Should be noted that figv shows an example implementation of the present invention; in other embodiments, implementation of the present invention a different sequence of bits and indexes can be used in a different order different from the order shown on figv.

[0037] of Course, the same bit or the second bit line 212 can be used to deactivate the same individual SS or multiple SS procedure deactivation. There are at least two ways communication between deactivation and activation, which are described in detail below in the example. According to the first method, using the value indicating the activation of SS is to map to the same entry of the bitmap for activation and deactivation, and UE-based activated or de-activated current status display of the SS or the SS group is aware of whether this indication to activate or to deactivate. In accordance with this method, the equipment UE determines that the second the bit sequence 212 is used to display the SS or the SS group, and changes the current state of activation of these display SS or SS group. According to the second method, based on the second bit sequence 212 is determined, can be activated or deactivated SS or the SS group, because any given index in the bitmap is either to activate or to deactivate the SS.

[0038] In an alternative embodiment, to indicate activation/deactivation CC configured for the UE, the second set of parameters bit field or bit sequence 212, which contains information about the activation, is associated with the configuration RRC bearing SS. This method is similar to the way the transmission report with the results of measurements in traditional systems, in which the value of the bit depends on the configuration of UE reported by RRC signaling. The first bit map is used to display the second bit sequence 212 to select at least one SS, if the configuration RRC bearing the SS to the UE is the first configuration and the second bit map is used to display the second bit sequence 212 to select the SS, if the RRC configuration is the second configuration, etc. So it's more effective to use different bitmaps for each configuration of the SS, in order eNB more flexibly implemented display using n is a large number of bits. Of course, these different bitmaps can be combined into one card with an additional entry for the configuration of the SS for the correct choice of the SS-based signaled the second bit sequence 212.

[0039] for Example, if the UE is configured for carrier aggregation SS with numbers 1 and 2, shown in figv, the second bit sequence 212 with a value of 011 may indicate that activated SS number 2. However, if the UE is configured for carrier aggregation SS with the numbers 1, 2 and 3, shown in figv, the second bit sequence 212 with the same value 011 may display an indication that activated SS with numbers 1 and 2. In the first case, the DCI format is obviously transmitted to the SS with the number 1, and in the latter case it is passed to the SS with the number 3, because before activation of these SS are the only carrier with which the UE performs the join.

[0040] In this exemplary embodiment of the present invention the size of the format 1A DCI shown in figv coincides with the size of the traditional format 1A DCI shown in figa. For a specific variant of implementation of the present invention are possible new DCI format (PDCCH), which does not match any of the existing DCI formats in regard to the mapping of bits on the SS, and in such scenarios, the implementation supports is Riki such a larger display can be used some other sizes of the DCI format, other than the size of a traditional format 1A. In other embodiments, implementation of the present invention can be used in a relatively small display, not to exceed the size of the existing DCI formats, such as format 1A, for example, by creating conditions for display on the configuration of the SS, and, as mentioned above, by using the reported bits. It is preferable not to increase the size of the DCI format, because any change in size lead to an increase in procedure time PDCCH blind search, which UE should perform to find their PDCCH.

[0041] After acceptance of the equipment UE this new DCI format, described in detail above, it is necessary to pass in the node eNB, sent this DCI, confirmation of reception of the information about the activation. Otherwise, the eNB may assume that SS is activated, and to transmit data or PDCCH in the new SS, but UE, which has received no indication of activation, you will not receive these new data or PDCCH in the new SS. Regardless of which of the above approaches is used in the embodiment of the present invention, the preamble, which the UE transmits in the eNB in the newly activated SS UL, specifies the eNB that the UE has received the message 200 activation. The confirmation, which in the embodiment of the present invention is a dedicated p is ambulu UE, specify the first bit sequence 210 also serves to eNB as a reference for setting THE PC, which UE should use the corresponding SS. The UE may transmit the preamble in one of the activated SS or, alternatively, in each of the SS, which requires a single parameter TA. Thus, the UE helps eNB to decide on the value of THE parameter or PC (depending on which one is used) for any particular SS. In another embodiment of the present invention, which is activated only channel DL in the newly activated SS, confirmation may be transmitted and received in the previously active channel UL activated SS agreed between eNB and UE, in order to avoid the transmission of additional data signaling used for channel selection UL used for validation.

[0042] the Second bit sequence 212 indicates a pair of SS UL/DL, which must be activated, or can activate many of the SS, as described above. Here's an example of a display method/type bitmap based on the second bit sequence 212 for the selected SS or multiple SS, which can be used in different variants of implementation of the present invention. In the first embodiment, the display bit map for the em bearing SS DL, which is already configured. This allows you to activate several SS at the same time. All SS UL, corresponding SS DL, are activated at the same time.

[0043] In the second embodiment, the display bit map separately corresponds to the bearing (bearing) SS DL and bearing (bearing) SS UL configured separately. In the third embodiment, the display bit map corresponds to the bearing (bearing) SS UL, which is already configured. This allows you to activate several SS at the same time. All SS DL, corresponding SS UL, are activated simultaneously. In the fourth embodiment, the display bit map is transferred directly to the E-ARFCN. In the fifth embodiment, the display bit map uses the mapping specified/notified for CIF (or UL CIF or DLCIF).

[0044] In regard to the mapping of bits on SS, there may be different number of SS in DL and UL for each UE. However, it is unlikely that this will cause the display to SS UL will vary from display to SS DL. This problem is solved by embodiments of the present invention, since each SS DL must in any case comply with its steam room UL CC, and that compliance should be known to the UE or to activate SS, or, if this correspondence explicitly unknown, should probably use a pair that is defined by default the Oia. It is more likely that in accordance with the current enhanced LTE-Advanced number SS UL may be less than the number of SS DL, but not Vice versa. This gives reason to consider the following examples of display capabilities.

[0045] In the example format 1A DCI shown in figv, box 206 destination RBA contains only 'individual' bits, and one or more bits of the second bit sequence 212 is used to display the SS. Can be used three additional bits for the CIF sequence PDCCH or more than three bits in the second bit sequence 212, depending on further progress in the development of the system of LTE-Advanced. In this case, in the exemplary embodiment of the present invention, the display may be performed in accordance with the display SS DL, and a dedicated preamble selected by the first bit stream 210 may be used in the preamble transmitted in the corresponding SS UL. These SS for UL and DL are activated simultaneously. Node eNB may use activated SS immediately after the period t of a predefined period, the information of which is not required signaling between the eNB and UE) to allocate new resources in the corresponding SS or after administration of the newly activated SS is allocated a preamble assigned to the first bit of the placenta is the sequence 210 in the sequence 200 PDCCH.

[0046] In another embodiment of the present invention when using the situation described above, the display field/second bit sequence 212 is used to display the UL, and all bearing DL displayed on SS UL (in the position indicated by the sequence PDCCH), are activated simultaneously with the corresponding SS UL.

[0047] If the cross-scheduling bearing already activated using the traditional format 1A DCI, like it's supposed to figa described above, field, CIF (if this field is in the format 1A) may be re-used, as in the normal provision of resources, while CIF is also contained in the new format 1A sequence PDCCH in which the bits 212 are used to activate the SS. That is, for a sequence PDCCH using the same procedure as for display on CIF SS. However, in the case of the sequence PDCCH, described in detail above, the resources are not available; all bits field 206 destination RB, shown in figv shall equal the unit, and, thus, neither format 1A or format 1A sequence PDCCH resources are allocated. However, these additional bits in the second bit line 212, shown in figv, can also be used for other display options, in addition to activation of the SS. Alternatively, the 3-bit CIF could the t be used to enable a larger number of bits for any display, required sequence PDCCH, or to display to activate SS, or to display the selected preamble or other display.

[0048] Regardless of the actual schema display, a dedicated RACH preamble, which is selected first bit sequence 210, activated SS is the confirmation for the eNB that the UE has received the message 200 activation, and can also serve as a reference point, if you have a possible new configuration of some parameters L1 level 1 (for example, if the adapted set of PDCCH monitoring or configuration ACK/NACK UL, what is not yet finally resolved in LTE-Advanced).

[0049] In an alternative embodiment of the present invention proposed re-specified format sequence PDCCH. In this format can be used bit sequence/bit field, which directly indicates the carrier SS subject to activation, for example, in the E-ARFCN. For optimized operation this format in the embodiment may also contain other low-level information, such as indication of the point in time at which the UE should start using the new sequence PDCCH, and information on the allocation of DL/UL.

[0050] For embodiments that use the new format after which outermost PDCCH, bits activate SS (which can also be placed in the second bit sequence 212) in the new sequence can, for example, to point directly at the E-ARFCN carrier subject to activation, or they can be an index (number), which indicates a previously known configuration. In this case, it is possible that you alarm UE in the display information, which must be a reference, e.g. message connection reconfiguration RRC, passed in the UE previously, when SS have been configured. Or it may be carried out alarm this information about how to activate SS in a separate message reconfiguration RRC connection after configuring bearing SS. The new format may also include more precise information about the timing for activation of the SS (e.g., SFN, within which the activation is assumed valid). In addition, the alarm information can be included in the reconfiguration message, the RRC connection, which contains information about the correspondence between indexes and configuration of the SS.

[0051] Thus, in General, the above-described specific technical effects of embodiments of the present invention is to create a new DCI format of the same size as the other conventional DCI format (in the example, the size of the new format 1A shown in figv coincides with the size of the traditional format 1A shown in figa). As mentioned above, in this format contains the first bit sequence 210, which includes as an index 208 of the preamble and the index 209 mask to indicate the selected preamble. In addition, there is a second bit sequence 212, which indicates what the SS (or SS group) must be activated. It should be noted that this embodiment is not limited to cases in which the available cross-scheduling of load-bearing.

[0052] Another technical effect of specific embodiments of the present invention lies in the rapid execution of the activation of the new SS using sequence PDCCH, which allows to solve the problem of reliability (and synchronization), because eNB listens to the preamble in activated SS UL, which is a confirmation that the UE has activated the corresponding SS DL (or group of bearing). Node eNB also aware that the UE listens to the SS (SS group), because UE need to know the location RACH, and UL limits the floor independently. Then eNB optionally may also adjust the parameters TA and PC, based on the adopted preamble. It should be noted that the presence of the field CIF is not required: the sequence PDCCH mo who has been transferred without field configuration CIF, to achieve the technical effect consists in the fact that you can activate SS, even if this is not possible or desirable to do using the CIF bits.

[0053] figure 3 in accordance with the exemplary embodiment of the present invention presents a scheme of signaling, where the UE connects using the first CC (CC1) and applies CC1 to signal to activate the second CC (CC2). At the beginning of the algorithm, shown in figure 3, the UE 10 is in the RRC connection state or mode 300, supporting for CC1 communication with the eNB 12, in which data is exchanged downstream a communication and upward 302b communication. Mode 300 RRC connection on CC1 supported during all operations, shown in figure 3. It is assumed that at the beginning of the algorithm, shown in figure 3, for a UE 10 is activated only CC1.

[0054] using the message 304, the node eNB 12 sends to the UE 10 sequence PDCCH, such as format 1A DCI shown in figv which carries the indicator for CC2 (for example, the second bit sequence 212) and an indication (for example, the first bit sequence 210) dedicated preamble (code word access), which the UE 10 should be used when accessing CC2. At this point in time, UE 10 should not be aware of that which of several SS the entire frequency band ( SS figv) is activated (activated). UE 10 via RRC signaling may be pre-configured for controlled set of aggregated SS, the number of which is less than the number of all possible SS. For example, in a controlled set of SS components aggregated SS equipment UE can enter the SS with the numbers 1, 2 and 3, shown in figv.

[0055] In block 306 based on the information contained in the sequence 304 PDCCH, equipment UE accesses its locally stored map and using the second bit sequence finds activated or activated SS. In this example, using the sequence 304 PDCCH is activated CC2. UE 10 activates for themselves CC2 by activating transmission of the dedicated preamble in CC2. This activation process is shown in the form of messages 308, in which the UE 10 transmits the packet random access on the RACH carrier CC2. Each of these packages 308 sent on RACH, includes a dedicated preamble UE, for which the UE 10 has received the indication in the sequence 304 PDCCH (in the first bit sequence).

[0056] In the end eNB 12 answers one of these packets, random access, transferred to the UE 10 by returning a response 310 random access. Usually this response is transmitted to eNB on PDCCH identified temporary identifier radio random access (RA-RNTI, random access radio network temporary identifier. Response 310 transmitted via PDCCH, among other parameters may contain information on the allocation of resources, TA and PA. UE 10 formally connects to the eNB 12 via CC2 using these resources, and at this point in time, as shown in block 312, the equipment is in the RRC connected mode for communication with the eNB 12 to CC2, and also in communication via CC1 established at the beginning of the execution of the algorithm.

[0057] figure 4 shows a diagram of the alarm system, similar to the scheme shown in figure 3, but illustrating another exemplary embodiment of the present invention, according to which is applied an index indicating the configuration. As in the scheme shown in figure 3, it is assumed that at the beginning of the execution of the algorithm, shown in figure 4, the UE 10 and the eNB 12 are in the mode 400 RRC connection only CC1, however, CC2 and SS3 (not shown) is also included in the monitored set BUE10.

[0058] still in connected mode RRC on CC1 node eNB 12 sends to the UE 10 message a reconfiguration RRC connection with which the equipment UE 10 reported which bitmap should be used to find the next correct SS subject to activation. In one of the embodiments of the present invention eNB directly transmits the bit map in the message a or eNB can indicate the type of display that you want to use. To the to above, display type referred to in this description may be determined by the configuration of the RRC equipment UE (previous configurations RRC and possibly also the current configuration). In addition, it may indicate that the display in the underlying transmission format sequence PDCCH is related directly to the E-ARFCN activated carrier. In any case, the UE 10 responds with a message 402b complete configuration of the RRC connection.

[0059] In the 404 message node eNB 12 sends to the UE 10 a sequence PDCCH, and from the previous message a alarm UE 10 retrieves information about how to display the second bit sequence in the sequence PDCCH. In block 406 transfers to the activated SS on the basis of information in the sequence 404 PDCCH, which, as figure 3 also includes an indication of a dedicated preamble and the display is activated SS (and in this case, the indication of activation of the SS, for example, is an index for the configuration of the RRC or E-ARFCN). UE converts the bit sequence in the sequence PDCCH using the display or by using a specific bitmap, which is transmitted to the equipment in message a, and determines that CC2 is activated by a sequence 404 PDCCH.

[0060] the UE 10 transmits the packet 408 is rosolino access on the RACH carrier CC2, each of which includes a dedicated preamble, the information on which the UE 10 is received in the form of a display in sequence 404 PDCCH.

[0061] the Node eNB 12 responds to one of these packages 408 random access by returning to the UE 10 by the PDCCH identified by the RA-RNTI, response 410 random access. Response 410 may contain, among other things, information about resource allocation, TA and PA. UE 10 formally connects to the eNB 12 via CC2 using these resources, and at this point in time, as shown in block 412, the equipment is in the RRC connected mode for communication with the eNB 12 to CC2, and also in communication via CC1 established at the beginning of the execution of the algorithm.
