The technical field to which the invention relates

The present invention relates to a device and method in a telecommunication system, in particular to the alignment of the synchronization transmission in a telecommunication system, which uses the Union of the component carriers.

The level of technology

Fig.1 illustrates a portion of a telecommunication network 10. A network of 10 radio access contains a number of radio base stations 11 (of which only one is shown in the figure), each of which communicates with multiple UE (user equipment) 12 located in the coverage area of a base station. The base station 11 performs additional communication with the core network 13. For example, if the network 10 is a standardized E-UTRAN (advanced network terrestrial radio access UMTS), the underlying network 13 has developed a batch basis, in turn, contains the object mobility management (MME), serving gateway and the PDN gateway (packet data network).

E-UTRAN currently supports bandwidth up to 20 MHz. However, one of the requirements to future editions of this standard, such as improved LTE support bandwidths of more than 20 MHz. Additional important future requirement is to ensure backward compatibility with previous releases. It also includes owls shall estimate on the spectrum. This implies that the media is the future release of a width of more than 20 MHz seems to be the current UE as set bearing. Each such carrier may be referred to as a component carrier. In particular, it can be expected that in the early applications of future editions will be fewer UE future release compared with many existing UE. Therefore, it is necessary to guarantee the effective use of a wide carrier also for existing UE, i.e. to make it possible to implement carriers where existing UE can be dispatched to all parts of the wideband carrier of the future release. A simple way to achieve this is the use of Association of the bearing. Association of bearing implies that UE future release can take a lot of bearing component, and the component carriers have or at least have the opportunity to have the same structure as that of the carrier of the previous releases.

Various examples of Association of the bearing illustrated in Fig.2A-2C. The adjoining bearing inside the band illustrated in Fig.2A, where five bearing component 20, each of which has a bandwidth of 20 MHz, United to form the bandwidth of 100 MHz. Fig.2b illustrates the Association of non-contiguous carrier inside the band, where t and bearing component 20, each of which has a bandwidth of 20 MHz, United together to form a combined bandwidth of 60 MHz. Finally, Fig.2C illustrates the Association of the bearing between the bands, where the two component bearing 20, in the band x and band y, respectively, each of which has a bandwidth of 20 MHz, United together to form a combined bandwidth of 40 MHz.

The number of merged component carrier and the bandwidth of a single component carrier may be different for uplink communications (UL) and downlink (DL). The symmetric configuration refers to the case where the number of component carrier in UL and DL is the same, while the asymmetric configuration refers to the case where the number of component carrier is different. It should be noted that the number of component carriers configured in the network may differ from the number of component carriers visible UE. The UE may, for example, to support more component carrier DL, than a component bearing the UL, even if the network is configured with the same number of component bearing the UL and DL.

The current E-UTRAN and improved LTE use DFTS-OFDM (extension of the discrete Fourier transform-multiplexing orthogonal frequency division) for modulation in UL DFTS-OFDM is a special form of FDM (multiplexing frequency division), where different users are assigned different parts of the spectrum. The orthogonality between different users relies on aligned at the time of the arrival of the UL signals of different users. In the current E-UTRAN and improved LTE uses a cyclic prefix, which somewhat weakens the alignment requirement on time. Therefore, it is sufficient if the signals are aligned within a part of the cyclic prefix. Normal cyclic prefix in LTE is around 5 MS; therefore, the signals from different users must be aligned within 1 μs or so.

UE synchronize their DL synchronization signals DL transmitted from the eNodeB, i.e. a base station E-UTRAN. The signals used for this purpose contain synchronization signals and reference signals. After establishing synchronization downlink UE may start to transmit signals in UL from the UE to the eNodeB with a well-defined offset from the synchronization DL. However, due to varying distances UE-eNodeB among the UE, the synchronization signals arrive in the UE at different points in time, creating a specific UE DL synchronization at each UE. This has resulted in different instances of transmission among UE. UE located next to the eNodeB, take the synchronization signal early and, thus, also begin predewatering their respective signals UL, therefore, you only need a short propagation time for arrival at the eNodeB. UE located far from the eNodeB, start sending later, and their signals UL also requires more time to complete the distance to the eNodeB that has resulted in a later time of arrival of the signals at the eNodeB. The difference in time between the arriving signals from two UE is the time difference bilateral signal transmission between the two UE. The bilateral signal transmission is defined as the length of time required for the signal to pass distance eNodeB-UE and back (assuming that the delay processing at the UE is zero) and is calculated as twice the distance eNodeB-UE, divided by the speed of light.

In order to align the arrival time of the UL signals from different UE, eNodeB measures the arrival time of various signals with respect to the desired reference time of arrival and informs the UE of how they should speed up or delay their synchronization transmission in UL (or on their synchronizations DL, specific to the UE, or relative to the current synchronization transmission in UL). This process is called balancing procedures synchronization, and the command used to notify the UE about the necessary correction, is called a command timing synchronization.

In the case of c UE with fully asinhronii vannoy synchronization UL, UE transmits no regular signal UL and the random access signal. This signal is specially created for unsynchronized UE. After eNodeB has identified the necessary correction synchronization transmission in UL, it passes the appropriate command timing synchronization of the UE, which adjusts its synchronization UL accordingly. After that, the UE may start to send regular signals UL, which imply aligned synchronization of arrival. eNodeB constantly monitors the synchronization of arrival of the signals UL and sends commands timing synchronization to maintain a valid synchronization UL. If the UE is not active in the UL for a long time or loses synchronization of the UL for any other reason, must be made a new random access to re-establish a valid synchronization UL.

In the case of the Association bearing the UL all the UL signals within the component carrier and/or related component bearing must be aligned synchronization to maintain orthogonality.

The implementation of the invention

In the following description, for purposes of explanation and not limitation, specific details such as particular sequences of steps, signaling protocols and device configuration to ensure a comprehensive understanding of the present invention. Specialist vannoy technology will be clear, that the present invention can be implemented in other types of exercise that do not have these specific details. In the drawings similar reference position refer to similar elements.

In addition, specialists in the art will appreciate that the tools and functions, explained below, can be implemented using the functionality of the software in combination with a programmable microprocessor or General purpose computer and/or using a specialized integrated circuit (ASIC). Also it will be understood that while the present invention is primarily described in the form of methods and devices, the invention may also be implemented in the form of a computer software product, as well as in the form of a system containing a computer processor and a memory associated with the processor, and the memory is encoded with one or more programs that may perform the functions disclosed herein.

The present invention disclosed in this document by reference to specific exemplary scenarios. In particular, embodiments of the invention described in a non-limiting General context in relation to E-UTRAN. However, it should be noted that the invention and its exemplary embodiments of implementation can also be applied to other the types of radio access networks, in applying the pooling of component carriers.

In the telecommunications system, which uses the merge component bearing UL, all signals UL within a component carrier and/or related component bearing must be aligned on synchronization to maintain orthogonality.

The arrival time of two or more component bearing the UL to the base station is affected by the synchronization of the transmission of each corresponding UL carrier, and the propagation delay experienced by each signal UL. However, in most cases, the arrival time of the component carrier UL is mainly determined by the synchronization of the transmission.

In accordance with the basic idea of the present invention, a base station receives a signal from the user equipment to component carrier UL and measures the time of arrival of a received signal. Correction synchronization of the UL transmission is determined based on the arrival time of the signal. Based on this, the base station determines which of the component carrier uplink connection used by the user equipment, the synchronization correction is valid. Correction and synchronization information is actually sent to the user equipment. The user equipment adjusts the sync is the grade of transmission on UL for each component carrier UL, for which the synchronization correction is valid.

The message carrying the information about which component carrier UL synchronization correction is valid, can be either an independent message, or it can be sent along with the correction of synchronization. Independent alarm information can actually be, for example, be signaled through RRC signaling (radio resource management) or controls MAC (media access). United message carrying and correction of synchronization, and information about reality, usually indicated as control MAC, but other schemes alarm systems are also possible. In one embodiment of the present invention, the synchronization correction is sent to the user equipment in the command timing synchronization.

In one embodiment of the present invention component carriers UL used by user equipment, associated with a common reference sync signal DL and, therefore, must have the same synchronization transmission by UL and must have the same synchronization reception UL, one command timing synchronization enough for all the component bearing the UL, the user equipment. The same Savatage applies when they use different but well-defined in relation to each other reference signals alarm DL. Synchronization of the UL transmission and, thus, synchronization of the reception of the UL will have the same relation to each other, and that the reference synchronization signal DL. Fig.3 shows user equipment 30, which is configured with a first component carrier 31 DL and the second component carrier 32 DL and the first component carrier 33 UL and the second component carrier 34 UL. Both the first and second component carriers 33, 34 UL derive their synchronization of the UL transmission from the first component carrier 31 DL. Thus, it requires only one team TA timing synchronization.

Common reference sync signal DL may be, for example, a synchronization signal or a reference signal of one component carrier DL. Another example of a common reference signal synchronization DL can be the synchronization signals on different component carriers if they are synchronized. The reference synchronization signal DL, which are not the same, but still have a well-defined relationship with each other, can be the synchronization signals on the component carrier DL, where synchronization transmissions are not the same, but still have a well-defined offset relative to each other.

In another VA who ianthe implementation of the present invention the reference synchronization signal DL are not related to each other. Fig.4 illustrates a user equipment 40, which is configured with a first component carrier 41 DL, the second component carrier 42 DL, and the third component carrier 43 UL. It is additionally configured with a first component carrier UL 44 and the second component carrier 45 UL. The reference signal synchronization first DL component carrier 41 DL is not associated with the reference synchronization signal DL of the third component carrier 43 DL. In order to guarantee explicitly defined synchronization reception by UL for both component bearing the UL required individual commands timing synchronization UL for each component carrier UL. Thus, the first component carrier 44 UL displays the synchronization of the UL transmission from the first component carrier 41 DL, and the second component carrier 45 UL displays the synchronization of the UL transmission from the third component carrier 43 DL. Thus, the user equipment receives the first command TA1timing synchronization and the second team TA2timing synchronization.

The example that should be used ahead of UL synchronization for each component carrier UL, takes place in the case of combining multiple component carrier duplex communication with time division (TDD) with different allocations of the DL and UL on them. Because the ku transmitters TDD DL usually aligned in synchronization with the neighbouring TDD DL transmitters for suppression, it is necessary that each component carrier TDD could establish your reference synchronization signal DL individually. Due to possible different allocations of the DL and UL need a separate synchronization reception UL, which requires a separate command timing synchronization UL.

The above-described embodiments of the invention will be further explained with reference to Fig.5a-b, 6 and 7.

Fig.5A is a block diagram of a method of determining correction synchronization transmission in uplink communication in a base station (BS) for communication in a telecommunication system of the present invention. In the telecommunication system uses the Association of component carriers. At step 50, the base station receives the signal on the selected component carrier uplink connection of several joint component carrier from the user equipment. Next, the base station measures the time of arrival of a received signal at step 51. Based on this, at step 52, the base station determines the correction synchronization transmission in uplink communication, i.e. the correction of synchronization, which is applicable to transmissions on the uplink communications from the UE, based on the measured arrival time. In the next step 53 determines the validity of the correction synchronization. That is defined for how the component bearing the upward communication line, used by user equipment, some correction of synchronization is valid. In one embodiment of the invention, the above definition is based on the reference clock signal downlink associated with the corresponding component carrier uplink connection used by the user equipment.

At step 54, the correction of synchronization and information about which component carrier uplink connection, the synchronization correction is valid, go to the user equipment. This can be done in different ways. The message carrying the information about which of the component bearing the UL synchronization correction is valid, can be either an independent message, or it can be sent along with the correction of synchronization. Independent alarm information as to which component carrier uplink connection, the synchronization correction is valid, can be performed using RRC signaling or using controls MAC. United message carrying and correction of synchronization, and information about reality, usually indicated as control MAC, but other schemes alarm systems are also possible. In od the om embodiment of the present invention, the synchronization correction is sent to the command timing synchronization at the user equipment.

In one embodiment of the invention, the correction of synchronization can be defined as valid for a component carrier uplink communication combined bearing component, which has an associated reference signal synchronization downlink aligned with the reference synchronization signal downlink associated with the component carrier uplink communication. In this case, the reference signal synchronization downlink may be a synchronization signal or a reference signal of one of the component carrier downlink used by user equipment.

In another embodiment of the invention, where the reference signal synchronization downlink associated with the component carrier is not the same, but has a well-defined relationship with the reference synchronization signal downlink associated with the selected component carrier, the correction of synchronization can be defined as valid for the mentioned component carrier uplink communication. That is, the correction of the synchronization is determined as valid for all component carrier uplink communication, which have an associated reference signal downlink with a certain offset from the reference signal nor the walking line associated with the selected component carrier uplink communication in which the signal is received from the user equipment at step 50. In this case, the reference signals of the downlink can be synchronization signals or reference signals on different component carrier downlink.

It should be noted that information about reality, i.e. the reality of correction synchronization in one embodiment, the present invention is defined during the installation of the base station and is sent to the UE when the added component carrier UL. Thus, information may actually be sent to the UE before the synchronization correction sent to the UE, and also less frequently than the correction of synchronization.

In an exemplary embodiment of the present invention, the base station measures the time of arrival of the signal received from the UE, and compares the measured time with a reference time of arrival. The reference arrival time can be a time of arrival, in which the base station wishes to receive a signal from the UE. Thus, correction of synchronization, a particular base station may be based on the measured time of arrival of a received signal and a reference time of arrival.

Fig.5b is a block diagram of a method of determining the correct synchronization of the front and upward communication in the user equipment for communication in a telecommunication system of the present invention. In the telecommunication system uses the Association of component carriers. At step 55, the user equipment sends a signal on the selected component carrier uplink connection of several joint component carrier to the base station. Based on this, the user equipment receives from the base station correction synchronization transmission in uplink communication and the information about which component carrier uplink connection, the synchronization correction is valid, at step 56. As mentioned earlier, this step can be performed in different ways. The message carrying the information about which of the component bearing the UL synchronization correction is valid, can be either an independent message, or it can be taken together with the correction of synchronization. Independent alarm information as to which component carrier uplink connection, the synchronization correction is valid, can be performed using RRC signaling or using controls MAC. United message carrying and correction of synchronization, and information about reality, is usually taken as control MAC, but other schemes alarm systems are also possible. In one embodiment, the Khujand is the implementation of the present invention, the synchronization correction is made the user equipment in the command timing synchronization.

In another embodiment of the invention, when the component carriers are the carriers duplex communication with time division with different allocations of the downlink or uplink communication bearing, correction of synchronization is determined only valid for the selected component carrier.

It additionally contains at least one block for identifying 640 correction synchronization transmission in uplink communication based on the measured arrival time and to determine which of the component carrier uplink connection used by the user equipment, a synchronization correction is valid. Finally, the transmitter 650 is contained in the base station for sending the correction of synchronization and information about which component carrier uplink connection, the synchronization correction is valid on custom hardware.
