The technical field to which the invention relates

In General, the present invention relates to methods and apparatus in wireless communication system supporting carrier aggregation. In particular, it relates to methods and devices for the transfer and application of system information broadcast in a multitude of aggregated cells.

The level of technology

Universal mobile telecommunications system (UMTS) is a 3G mobile communication technologies designed to change the GSM (global system for mobile communications). Long-term Development (LTE) 3GPP is a project in the framework of the project third generation partnership (3GPP) that is intended to improve the UMTS standard to meet future requirements in the context of improved services such as higher data transfer speed, improved efficiency and lower costs. Universal network terrestrial radio access (UTRAN) is the radio access network of the UMTS system, and the evolved UTRAN (E-UTRAN) is the radio access network of the LTE system. As illustrated in Fig.1, radio access network typically includes a user equipment (UE) 150, connected wirelessly with the base stations (RBS) 110a-c, commonly called NodeB (Node B, NB) in UTRAN and eNodeB (evolved Node B, eNB) in E-UTRAN.

E-UTRA, in accordance with the version 8 (Rel-8) specification� 3GPP, supports bandwidth up to 20 MHz. However, it is expected that one of the requirements of future versions of this standard will support bandwidths of more than 20 MHz. An additional important requirement for such versions is to guarantee backward compatibility with Rel-8. Also it should include spectral compatibility. This would imply that a bearing on a future version, wider than 20 MHz, should act as a certain amount of bearing from Rel-8 UE based on Rel-8. Sometimes each such carrier is called a component carrier (CC). In particular, for early stages of system implementation future versions can be expected that there will be fewer the UE based on a future version compared to many legacy UE based on Rel-8. Therefore, it is necessary to ensure the effective use of a wide carrier also inherited UE, i.e. what is possible to realize a bearing in which the legacy UE can be dispetcherskuyu in all parts of the broadband carrier in a future version.

A simple way of obtaining this result could be the use of carrier aggregation. The carrier aggregation implies that a UE based on a future version can receive and send on the set CC, and CC have, or at least have the opportunity of having such a well� patterns, what carrier and for Rel-8. The carrier aggregation is illustrated in Fig.2a, where five CC 210, with a bandwidth of 20 MHz are aggregated together to form an aggregated bandwidth of 220 bandwidth of 100 MHz. The carrier aggregation is planned for version 10 (Rel-10) specifications 3GPP LTE.

Carriers can be aggregated adjacent, as illustrated in Fig.2a, or they may be aggregated from intermittent plots in the frequency domain (which is also sometimes referred to as spectrum aggregation). Fig.2b schematically illustrates an example non-contiguous carriers.

Using the concept of carrier aggregation may be possible, inter alia, support for:

- Higher speeds of transmission bits;

- The formation of non-contiguous spectrum - that is, for high speed bit transmission rate and better throughput, even in cases where the operator is adjacent spectrum;

- Fast and effective distribution of the load between carriers.

The carrier aggregation or LTE spectrum in has several features in common with such concepts as HSPA with two or multiple carriers (DC or MC), which combine one or many carriers in UTRAN.

It should be noted that carrier aggregation can be considered as a concept that is oriented to the UE, which UE can be configure�owano to use, for example, the two leftmost CC (230) in Fig.2b, another UE can be configured to use only a single CC, such as the right CC (250) in Fig.2b, and the third UE may be configured to use all CC (230, 240, 250) of Fig.2b. Thus, the UE may be configured with a component carrier (CC) on a carrier of a certain frequency within the same frequency band, or within other frequency bands. Many CC uplink (UL) and downlink (DL) configured independently from each other, which means they are not necessarily configured in pairs UL/DL, as in Rel-8/9 specification 3GPP LTE. Possible and asymmetric configuration, where the number of configured UL CC different from the number of configured DL CC.

Initially, the UE is configured with one pair of UL/DL CC on which it performs an initial random access. These CC are called primary component carrier (PCC). In addition to a pair of UL/DL PCC, the eNB may, if necessary, to configure the UE with additional CC, so-called secondary component carriers (SCC).

Traditionally, the carrier is a plot of the frequency spectrum that can be used for transmission on UL and/or DL. The concept of a cell is usually used to refer to a radio network object that can be�ü uniquely identified by a UE. For example, in the UTRAN cell is identified by the identification information of a cell, which is broadcast on the geographical area from one UTRAN access point. Typically, the honeycomb is connected with one pair of bearing UL and DL in FDD (full duplex communication frequency division), and with one carrier that provides both UL and DL resources while in the TDD mode (full-duplex communication with time division). There could be many hundred associated with one carrier, while the cell is physically separated from each other. This is the case, for example, when each neighboring eNB implements a cell on the same carrier.

As mentioned above, future versions of the e-UTRAN administered support higher bandwidth or frequency spectrum, and, for compatibility reasons, additional bandwidth may appear in the form of additional carriers, for example 20 MHz, the so-called component carriers (CC) are aggregated together. However, when applying the concepts of the honeycomb, which is the object of the radio network, associated with a specific CC - cell, which can be identified through UE - UE using carrier aggregation in connected mode, may also be referred to as United with many of the aggregated honeycomb: one primary serving cell (above PCC, and which are also used such lettering�, as PCell, primary serving cell and the serving cell) and with further configured CC, which are part of another set of secondary cells (SCC above, and which are used for such designations as SCell, secondary serving cell and a secondary cell).

In LTE is discussed many different scenarios and types of bearing, including the aggregation backward compatible carrier Rel-8. Also discusses the bearing without the possibility of backwards compatibility, and enhanced load-bearing. Such carriers may not be available for terminals based on Rel-8. Private and an example of a likely scenario of carrier aggregation includes the case when aggregated for the UE with two or more carriers/cells Rel-8 downlink. It should be noted that carrier aggregation is usually and in most cases is related to an attached UE, which is the UE that is actively involved in the transmission to the eNB and from him, and therefore has a connection with the eNB, the Manager of aggregated carriers/cells.

Thus, the aggregated carriers/cell can also be accessible by the UE based on Rel-8, which means that each of the carriers/cells can be accessed independently to operate in one mode of the honeycomb. This work in single cell includes a transition to the standby mode that is activated in a situation where UE, p�Avila, is inactive, and the operation in the connected mode in single cell. Consequently, these are compatible with Rel-8 carriers/cell will need to provide system information (SI), which is broadcast in a cell so that the UE can perform, for example, the transition to standby mode and cell selection in accordance with the rules determined by parameters broadcast in SI. Other settings that are of great significance, which should be broadcast in each of the carriers/cells Rel-8, are parameters that are related, but not limited to:

- The parameters of the random access (RA) and RA channel (RACH), that is, the parameters that determine how the UE should access the cell;

- The parameters UL, i.e., common parameters, e.g. related to UL bandwidth, frequency, PUCCH (physical control channel uplink) and PUSCH (shared physical channel uplink);

- Parameters DL, that is, the common parameters, e.g. related to PCFICH (physical channel indicator format control), PDSCH (shared physical channel downlink), the paging information, the DL frequency and bandwidth.

- Cell-specific timers and constants.

SI also includes, for example, sets of parameters associated with SEL�honeycomb ROM and radio access technologies (RAT). The term "General settings" is used to indicate the options that you want to get many or all UE in a cell, in accordance with certain rules in the spec. Such common parameters as a rule, will be read and used by many UE. Can be defined deviations from this General rule.

In Rel-8, SI relating to the connected mode UE is allocated in the main information block (MIB) and in the first two blocks of system information (SIB1 and SIB2). Can be determined that the UE needs to maintain updated information of this desired SI, as defined in the 3GPP standard. If SI is changed, then the UE shall be notified through various means to try to obtain their desired SI.

It is also possible that the bearing/honeycombs without the possibility of backwards compatibility may be available for transition to standby mode and operation mode of a single cell. In this case, these carriers/cell will also be broadcast SI with sets of cell-specific parameters such as described above.

Typically, DL honeycomb will include a translation of the parameters SI that belong to this cell, including the parameters of both the DL and UL. From a technical point of view, it would be possible, in addition to the above parameters, to transmit the parameters associated with the second cell, DL first cell. However, this solution may not be preferred because then the parameters associated with the second cell should also often be broadcasted on the DL for the second cell. This duplication is not desirable, and, therefore, in 3GPP agreed not to broadcast in Rel-10 information relating to the second cell, the first cell.

In the usual case, illustrated by the diagram of signal transmission in Fig.3a, the first UE 310 is connected to one hundredth, also called a primary cell according to the procedure 301 connection setup RRC, similar to those known from Rel-8. Only then, on the basis of various criteria, the eNB 320 may decide to configure the UE 310 to receive (DL) and transmission (UL) on the set of aggregated carriers/cells. This means that the eNB 320 may send a configuration message, usually a message 302 RRCConnectionReconfiguration (___rrc), which includes additional information about UL and DL CC, which, presumably, will be used by the UE. UE responds to the configuration message, usually a message 303 RRCConnection ReconfigurationComplete (___rrc_).

Now, the connected mode UE will be aware of the many UL and DL CC that may be aggregated to a very large bandwidth and UE now ready for dispatching navseh CC, sometimes on a separate CC, and sometimes on all CC at the same time. Therefore, there is now an SI that is available on multiple component carriers DL or cells with which the UE configured. However, as described above, this required SI also has to do with UE, operating in the same cell, such as UE based on Rel-8, in which there is no possibility of carrier aggregation. It may happen that a part of SI that is relevant to this work in single cells, not valid, not useful, and possibly even harmful, because it may lead to undesirable restrictions in the flexibility of the work on carrier aggregation, as will be further described below. Thus, the problem is that SI, which has to work in single cell that is broadcast in all cells, for example, for backward compatibility, but if the honeycomb should be used for carrier aggregation, this SI single cell is not optimal.

Now, let us consider the above example where the first UE was connected to one hundredth of a primary cell, which includes both the configuration of the DL and UL, and the fact that UE is configured to aggregate one additional DL carrier of the secondary cell. Additionally, assume that SI is related to bearing DL, is broadcast in both aggregated honeycomb�H. However, as noted above, SI, broadcast in each of the comb will provide SI, also relevant to the mode one carrier. Consequently, the SI transmitted in the secondary cell, will include information about the appropriate configuration of UL, including, for example, the UL bandwidth and frequency parameters RACH, PUCCH and PUSCH. Therefore, if UE running multiple aggregated carriers, are required to read and follow SI broadcasted in the primary or secondary cell, which will lead to a situation where UE, if necessary, also configure all relevant parameters for operation in single cell.

In the following example, RBS operates three bearing UL and DL in three cells, denoted here as UL1/DL1/cell1 (UL1/DL1/SATA), UL2/DL2/cell2, and UL3/DL3/cell3. When working in single cell, carriers are connected in such a way that UL1 is working together with the DL1, UL2 with DL2, and UL3 with DL3, respectively. Consequently, any SI related to ULx/DLx, airs in cellx, as illustrated in Fig.2c. Note that the example does not exclude the fact that ULx has the same frequency as the DLx that in the TDD mode.

It is assumed that the UE is connected to cell2 defined by DL2, that is, the UE 310 follows known procedures from Rel-8, reads the desired SI in DL2 and UL2 uses for transmission on UL (status 304 in the diagram of signal transmission of Fig.3b). To�ome, now eNB 320 wishes to configure the UE 310 by means of two additional bearing DL, since the eNB determines that the UE requires more bandwidth DL. In step 305, the eNB sends a configuration message that includes information indicating that the UE may optionally use a DL1 in cell1 and DL3 in cell3, in addition to the already existing DL2. However, now if the UE reads the desired SI, also broadcast in cell1 and cell3, we follow the existing prior art, the UE will also use the appropriate configurations UL, ie, UL1 and UL3. Of course, this is not desirable because the eNB detects the reasons for aggregation only of bearing DL in this case and not for the configuration of the UE with additional UL bandwidth that significantly exceeds the needs of the UE. Consequently, the current level of technology does not provide the flexibility that SI is relevant to the operation of a single cell, may be too restrictive for carrier aggregation.

Another example is, for example, the configuration of the random access (RA). Now suppose that UE is configured with two aggregated cells both in UL and DL, for example, UL1/DL1 in cell1 and UL2/DL2 in cell2. The parameters SI, belonging to the carrier frequency and bandwidth, broadcast in both cells, are relevant to this case. However, both SI hundred incl�t the parameters RA, offering UE the ability to perform RA on both bearing the UL. It may happen that the eNB may wish to limit the UE performing the RA only on one particular available from UL. At the present level of technology, it is impossible, because the UE will read the SI containing the parameters RA in both cells, and therefore will perform RA on both UL.

An additional example relates to, for example, the PUCCH control. Recently it was agreed that it should be possible providing all the control information on PUCCH single UL carrier, regardless of the number of load-bearing UL and DL are configured for the UE. In the examples illustrated above, each cell will provide independent options PUCCH. However, the UE must follow only the parameters PUCCH transmitted in one of the cells.

Another example relates to timers and constants. Each of the aggregated cells can provide independent values timers and constants can have different values. However, timers and constants can be related not to the honeycomb, but rather to the UE. For example, UE can have only one timer t1, which expires when reached the value of T1, but SI in all cells and provides various values for this T1, and it is unclear which values UE shall apply.

Detailed description

In the following, the invention will be described in more detail with reference to specific variants of implementation and the accompanying drawings. For purposes of explanation, but not limitation, formulated characteristic details such as particular scenarios and methodologies to ensure complete understanding of the present invention. However, specialists in the art it will be obvious that the present invention may be implemented in other embodiments that depart from these specific details.

In addition, specialists in the art will understand that the functions and means explained later in this document, can be implemented using software functioning in conjunction with a programmed microprocessor or General purpose computer, and/or with the use of specialized and�agrilinae chip (ASIC). Also it will be understood that, although the present invention is primarily described in the form of methods and devices, the invention may also be implemented in a computer program product, and system containing a computer processor and a storage device associated with the processor, and a storage device encoded with one or more programs that may perform the functions disclosed herein.

Embodiments of the present invention is described herein with reference to specific exemplary scenarios. In particular, embodiments of the invention described in non-limiting General context with respect to E-UTRAN. However, it should be noted that the invention and variations in its implementation can also be applied to other types of radio access networks configured to use carrier aggregation. It should be noted that the designations and terminology used in the description may change that in no way limits the applicability of embodiments of the present invention.

In embodiments of the present invention, the problem that the system information (SI) broadcasted in the comb wireless communication system, is not suitable for the UE which operates in the mode of aggregation �essig, is eliminated by the solution in which the UE, while configuring it through eNB for aggregating two hundred, applies the rule configuration to identify in which of the hundred, it should read the broadcasted SI. The rule configuration may be provided by the eNB in a dedicated configuration message, and it also highlighted message may include configuration parameters that are required for configuration of the honeycomb, which was not read broadcast SI.

In one or more embodiments of the present invention, the eNB is configured to broadcast SI containing a set of configuration parameters, and transmit information to the UE operating in carrier aggregation, which allows UE to use SI, broadcast in only one of the aggregated cells.

In additional embodiments of the present invention, the information transmitted to the UE operating in the mode of aggregation of load-bearing:

is transmitted in the form of selected information, and/or

- includes settings that override the settings from SI some cells that have not been read and/or

- manages the UE in order to follow SI from one of the many carriers.

Thus, embodiments of the present invention include a solution in which the UE will not follow any SI, before�provided on a specific DL carrier, and in which all relevant information provided by dedicated signalling.

Detailed embodiments of the present invention are illustrated using an example. Again consider the above example where the eNB manages three carrying UL and DL in three cells, denoted here as UL1/DL1/cell1, UL2/DL2/cell2 and UL3/DL3/cell3. Bearing DL provide SI with respect to each pair of DL and UL so that ULx configured in SI, given by DLx in cellx. Now, UE establishes a connection with the cell defined by SI on the first DL carrier (e.g., cell1 and DL1), that is, after the establishment of the UE is prepared to send and receive (i.e., be subject to scheduling) on UL1 and DL1, respectively.

Now eNB configures the UE to also use downward communication line DL2 in cell2, usually by sending of the RRCConnectionReconfiguration message including information about additional DL2, which is offered for UE for adoption in use. Now, cell1 is the primary cell and cell2 is a secondary cell. In accordance with one variant of implementation of the present invention, the eNB can now send a dedicated configuration message to the UE, wherein the message contains the parameters SI, with respect to the carrier DL2. For example, this is a dedicated configuration message m�may be contained in the RRCConnectionReconfiguration message. Thus, UE after receiving the configuration message prepared for the reception of the data by both DL1 and DL2, even though it was considered only on SI DL1.

In accordance with another variant implementation of the present invention, the eNB transmits SI to the set of supporting downlink or comb (DL1-3/cells1-3 in the example), each of which provides the same set of parameters, for example, but not limited to, timers, and constants. Also, the eNB provides information about which of the many sets of parameters should be used, that is, in which of the cells the UE needs to read the SI. This information is included in the rule configuration, with one hundred set the status of the different configurable cells so that the UE satisfies the conditions of the parameters obtained from cells with different status.

In one embodiment, the implementation, honeycomb with different status is the primary cell, so the UE reads the SI transmitted in the primary cell, that is, in cell1 in the above example. In another variant implementation, the information provided by the eNB, also contains an indication of which cells is the primary cell, as the configuration of the honeycomb is primary over time may change. The honeycomb, which was originally the primary (cell1 in the example), e.g.�, at a later stage compounds may instead be a secondary cell.

Fig.4 is a block diagram of a method for UE in wireless communication system supporting carrier aggregation, in accordance with one variant of implementation of the present invention. The system contains the RBS, such as the eNB, configured to broadcast system information in all its client the comb. Also, the eNB is able to aggregate its client cell. The method illustrated in the flowchart includes the following steps:

- 410: Receiving configuration information for an aggregation of two or more cells from the eNB. In this example the aggregation of only two hundred. In the first variant of implementation, the configuration information can be adopted in a dedicated message, such as an RRCConnectionReconfiguration message containing information on two cells, the aggregation of which UE can perform.

- 420: Identification of the first of two hundred based on the configuration rules stating that the first of the two cells has a status that differs from the status of the remaining cell. In the second variant of implementation, the rule configuration may be contained in the received configuration information. However, it can also be pre-defined rule configuration that reduces overhead when transmitting signals.

- 430: Reading t�ancoraimes SI identified only in a cell.

In the third embodiment of the present invention, the honeycomb with a different status is a primary cell, which means that the primary cell is identified honeycomb, which should be read SI. In addition, in the fourth embodiment of the adopted configuration information also includes an indication of which of aggregated cells is a primary cell (or, more generally, which of aggregated cells is a cell with a different status). This is necessary because it is possible that the eNB performs the change of the primary cell, which means that the other cell, which was previously a secondary cell configured to be the primary cell. Therefore, this change should be communicated to the UE for the UE to identify the correct cell, in which SI should be read based on the configuration rules. In the fifth variant implementation, the configuration information also contains configuration settings that should be used instead of the parameters SI, which is broadcast in the remaining cell, for example, in a secondary cell. Since the SI transmitted in the secondary cell, is not read by the UE, instead, UE will use the configuration settings provided in the configuration information corresponding to configuration of UL and DL in aggregated cells. Description�record above embodiments of the first through fifth can be combined in any way possible.

Also optionally, the method includes the satisfaction of conditions (or application), in step 440, at least one parameter obtained from a few SI. Thus, in one embodiment, the implementation, the UE reads and satisfies the conditions of at least one parameter that is transmitted in the primary cell. This or these few and satisfied the parameters are parameters that are valid for the UE in the mode of aggregation of carrier, all other necessary configuration parameters may include, for example, in a dedicated configuration message.

Fig.5 is a block diagram of a method RBS in wireless communication system supporting carrier aggregation, in accordance with the second variant implementation of the present invention described above with reference to Fig.4. For example, RBS can be an eNB in E-UTRAN. the eNB is capable of transmitting data to the UE in two aggregated cells. The method illustrated in the flowchart includes the following steps:

- 510: Broadcast SI in both cells. SI broadcasted in the cell that contains the configuration settings that are specific to this cell.

- 520: Transfer configuration information to aggregate two hundred to the user equipment, wherein the configuration information contains a rule configuration that establishes that the first of these two cells has a status�, which differs from the status of the remaining cell. This is done for reading by a user equipment of the broadcasted system information only in a cell with the different status, as described above. In the first variant of implementation, the configuration information is transmitted in a dedicated message. In one embodiment, the implementation described above with reference to Fig.4, rule configuration is pre-defined, and should not be contained in the transmitted configuration information, which reduces the amount of signal transmission.

In the third embodiment of the present invention, the honeycomb with a different status is a primary cell. In addition, in the fourth embodiment of the transmitted configuration information also includes an indication of which of aggregated cells is a primary cell (or aggregated honeycomb is one hundredth with different status). In the fifth variant implementation, the configuration information also contains configuration settings that should be used instead of the parameters SI, which is broadcast in the remaining cell, for example, in a secondary cell. Embodiments of the first through fifth described above can be combined in any way possible.
