Method and apparatus for synchronizing resource allocation indication information order in a wireless network

The present invention relates to wireless communications, and more particularly to base stations and user terminals based on carrier aggregation in LTE-A.

At present, multi-carrier communication technology has been more and more widely researched and applied. For example, the LTE-A (Advanced Long Term Evolution) standard uses Carrier Aggregation (CA) as the main technology to improve system performance. According to current standards, the LTE-A standard supports up to five Component Carriers (CCs), each of which can have a bandwidth of up to 20 MHz. In the current standard, in the case of non-MIMO, the following data transmission is taken as an example, and a corresponding resource allocation information is generated for each component carrier for indicating the corresponding transmission resource on the component carrier. Block, which means that for the LTE-A transmitter, one Transmission Time Interval (TTI) will have up to five resource allocation indication information generated; and the receiver such as the user equipment is in one transmission time. Up to 5 resource allocation indications can be received simultaneously in the interval.

In the existing LTE system, only one transport block is used for uplink or downlink data transmission in one transmission time interval. Therefore, the data to be transmitted is directly encapsulated in the data block, and then subsequent transmission processing is performed. However, in the LTE-A system, when the base station and the user terminal adopt the carrier aggregation mode, one transmission time interval may include multiple component carriers, and each carrier component respectively corresponds to corresponding resource allocation indication information for indicating The allocation of the resource blocks. Therefore, the base station determines the order of the respective transport blocks indicated by the resource allocation indication information according to the resource allocation indication information, and according to the order information, encapsulates the user data in the downlink data according to a predetermined rule. In each transport block, for the uplink data, the received data in each transport block from the user terminal is decapsulated according to a predetermined rule, and at the same time, in order to maintain synchronization with the user terminal, the base station needs to allocate the resource. The notification information informs the user terminal.

1 shows a wireless network system composed of a base station 1 and a user terminal 2 according to an embodiment of the present invention, wherein the base station 1 and the user terminal 2 may further include a relay station or the like as needed, for convenience. Note that the intermediate device is omitted in FIG. 1, and only the base station 1 and the user terminal 2 are shown. The user terminal 2 is configured with four component carriers, which are respectively CC1, CC2, CC3, and CC4. The bandwidth of the component carrier may be different according to the application scenario, and the size of each carrier does not exceed 20 M. In this embodiment, The bandwidth of the four component carriers is configured to be 20M. It can be understood that the base station configures no more than five component carriers for one user terminal.

2 shows a system flow diagram in accordance with an embodiment of the present invention.

First, in step S20, the base station 1 generates resource allocation indication information corresponding to each component carrier, and the resource allocation indication information is used to indicate related information of resources allocated to the user terminal 2, that is, each component carrier Each of the foregoing corresponds to a resource allocation indication information, that is, a UL grant or a DL assignment. The UL grant includes resource information allocated for transmitting the uplink data to the base station 1 by the user terminal 2, for example, the sequence number of the allocated initial resource block and the termination. The sequence number of the resource block and the modulation and coding mode corresponding to the allocated resource block. The DL assignment includes resource information allocated for transmitting the downlink data to the user terminal 2 by the base station 1, for example, the sequence number of the allocated start resource block and the sequence number of the terminated resource block, and the modulation sum corresponding to the allocated resource block. Encoding.

For the downlink data transmission, in order to effectively encapsulate the data in the transport block (TB) indicated by the resource allocation indication information, the base station 1 needs to number the resource allocation indication information, that is, obtain the resource. The order identification of the indication information is assigned, and the data is sequentially encapsulated in a transport block indicated by the resource allocation indication information identified by each of the different orders according to a predetermined rule. Similarly, for the uplink data from the user terminal 2, when the base station 1 receives a plurality of transport blocks from the user terminal 2, the base station 1 also needs to know the order identifier of each transport block, and according to a predetermined rule, from the user. The data of the terminal 2 is decapsulated.

Therefore, in step S21, the base station 1 determines the order identifier of each resource allocation indication information based on each resource allocation indication information. Hereinafter, the method for numbering the resource allocation indication information by the base station 1 will be specifically described by two specific embodiments.

Static or semi-static

The base station 1 may determine the order identifier of each resource allocation indication information corresponding to each component carrier according to the order identification of the component carriers, that is, the number of the resource allocation indication information. For example, the number of resource allocation indication information corresponding to CC1 is 1, the number of resource allocation indication information corresponding to CC2 is 2, and the number of resource allocation indication information corresponding to CC3 is 3, and the resource allocation indication information corresponding to CC4 is The number is 4. In another embodiment, if the user terminal 2 is configured with three CCs, for example, CC1, CC3, and CC5, respectively, the resource allocation indication information corresponding to CC1 is numbered 1, and the resource allocation indication corresponding to CC3 is The number of the information is 2, and the number of resource allocation indication information corresponding to CC5 is 3. Certainly, the foregoing manner is only an example, and those skilled in the art may understand that the resource allocation indication information corresponding to CC1 may be 4, and the resource allocation indication information corresponding to CC2 is 3, and the resource corresponding to CC3. The number of the allocation indication information is 2, and the number of the resource allocation indication information corresponding to the CC4 is 1 to determine the number of the resource allocation indication information. Since the component carrier and the resource allocation indication information are in one-to-one correspondence, the order identification of the resource allocation indication information can be conveniently determined in this manner.

Dynamic mode

In addition to the foregoing manner of determining the order identifier of the resource allocation indication information according to the order identification information of the component carrier, the order identifier of the resource allocation indication information may be determined according to the nature of the resource indicated by the resource allocation indication information.

Because the resource allocation indication information includes the size information and the modulation and coding mode of the resource block allocated to the user terminal, the base station 1 may also sort the resource allocation indication information according to the size of the resource block and/or the modulation and coding manner. . For example, if the base station 1 sorts according to the size of the resource block, the resource allocation indication information number indicating that the user terminal 2 is allocated the largest resource block may be numbered 1, and the resource indicating the second largest resource block is allocated to the user terminal 2. The assignment instruction number is 2, and so on. If the base station 1 sorts the resource allocation indication information according to the modulation and coding mode used by the resource block, for example, the base station 1 may use the resource allocation indication information indicating that the resource block adopts the high-order modulation and coding mode as the number 1, the order The lower the number, the larger the number. For example, for the resource allocation indication information indicating that 64QAM, 16QAM, and QPSK are respectively used, the base station 1 indicates that the resource allocation indication information number indicating that the modulation and coding mode is 64QAM is 1, and the resource allocation indication information indicating that the modulation and coding mode is 16QAM is indicated. The number is 2, and the resource allocation indication information indicating that the modulation and coding mode is QPSK is number 3. Among them, a 64QAM constellation point can carry 6bit information at the same time, a 16QAM constellation point can carry 4bit information at the same time, and a QPSK constellation point can carry 2bit information at the same time.

Of course, the base station 1 can sort the resource allocation indication information in combination with the allocated resource block size and modulation and coding manner in the resource allocation indication information. For example, the resource allocation indication information is first sorted according to the resource block size. If the resource block sizes indicated by the respective resource allocation indication information are the same, the resource allocation indication information is sorted according to the order of the modulation and coding modes. Of course, the resource allocation indication information may be first sorted according to the order of the modulation and coding modes, and then according to the resource block size. This dynamic approach eliminates the need for additional signal overhead and saves bandwidth resources. However, there may be a case where the resource block size indicated by each resource allocation indication information is the same, and the modulation and coding methods used are also the same. Therefore, static or semi-static mode is required at this time, that is, the base station 1 The order identification of each resource allocation indication information corresponding to each component carrier is determined according to the order identification of the component carriers.

Of course, the base station 1 needs to notify the user terminal 2 of the rule of how to determine the order identification of the resource allocation information, so that the user terminal 2 can know whether to determine the resource allocation information according to the size information of the resource block or according to the modulation and coding mode or a combination of the two. Order identification.

Since the base station 1 generates these resource allocation information, the base station 1 knows the order identification of these resource allocation indication information.

Then, in step S22, the base station 1 identifies the user data according to the order of each resource allocation indication information, encapsulates the user data in each transport block corresponding to each resource allocation indication information, and transmits it to the user terminal 2 according to a predetermined rule. . First, the following data is taken as an example for explanation. For the downlink data, for example, when the base station 1 has multiple services that need to be sent to the user terminal 2, each of the services includes a minimum amount of transmitted data, and the minimum transmitted data amount represents a lower limit of the amount of data for transmitting the service, and therefore, The predetermined rule includes: the base station 1 first encapsulates the minimum transmission data amount of each service in the transport block indicated by the DL assignment numbered 1, and if the transport block has remaining resources, the service with the highest priority order is used. The remaining data is repackaged into the transport block. Then, if the transport block indicated by the DL assignment numbered 1 is already full, the remaining data of the service with the highest priority is repackaged into the DL assignment numbered 2 In the indicated transport blocks, and so on, to optimize the flow of the logical channel prioritization. Of course, the predetermined rule may also be: the base station 1 first encapsulates the minimum transmission data volume of each service in the transport block indicated by the DL assignment numbered 4, if the transport block has remaining resources. , the remaining data of the service with the highest priority is repackaged into the transport block, and then, if the transport block indicated by the DL assignment numbered 4 is already full, the remaining data of the service with the highest priority will be The packet is then encapsulated into the transport block indicated by the DL assignment numbered 3, and so on, thereby optimizing the flow of the logical channel prioritization.

Then, in step S23, the base station 1 notifies the user terminal 2 of the resource allocation instruction information. The base station 1 notifies the user terminal 2 of the UL grant or DL assignment message through a Physical Downlink Control Channel (PDCCH). Those skilled in the art will appreciate that there is no apparent prioritization between step S22 and step S23.

In another embodiment, the base station 1 also needs to identify the order of each component carrier, that is, the CC Index notifies the user terminal 2, for example, CC1, CC2, CC3, and CC4. The base station 1 can transmit the CC index information by using a broadcast channel, such as a Physical Downlink Shared CHannel (PDSCH) or a Physical Broadcast Channel (PBCH), or use a dedicated channel, for example, using high-level control information, for example, Radio Resource Control (RRC) or media access control layer control messages are transmitted.

In another embodiment, the base station 1 notifies the user terminal 2 of the order identification of each component carrier and the correspondence between the component carrier and the frequency point. The base station 1 can transmit the CC index information and the correspondence by using a broadcast channel, such as a physical downlink shared channel or a physical broadcast channel, or the base station 1 can use a dedicated channel, for example, using high-level control information, such as a radio resource control message or media access control. Layer control messages are used to transmit CC index information and correspondence.

In step S24, the user terminal 2 receives resource allocation indication information corresponding to each component carrier from the base station 1, and the resource allocation indication information is used to indicate related information of resources allocated to the user terminal.

Then, in step S25, the user terminal 2 determines the order identifier of each resource allocation indication information based on each resource allocation indication information.

For example, if the base station 1 sends a UL grant message on the DL CC of the PDCCH channel, the user terminal according to the DL CC and the System Information Block 2 (SIB2), the SIB2 includes the uplink and the downlink. The user terminal 2 can acquire the component carrier to which the UL grant is applied. In addition, when the PDCCH includes a carrier indication field (CIF), the user terminal 2 can also acquire the PDCCH according to the information in the CIF. The component carrier in which the UL grant or DL assignment is applied.

In addition, the user terminal 2 knows in advance whether to obtain the order identifier of the resource allocation indication information in a static manner or in a dynamic manner. For example, the base station 1 notifies the user terminal 2 of the manner through the configuration information of the upper layer, and of course, adopts static or dynamic The manner may also be that the system has been configured in advance, and therefore, the base station 1 is not required to signal the user terminal 2.

When the user terminal 2 knows the order identifier of the resource allocation indication information in synchronization with the base station 1 in a static manner, the frequency of the component carrier corresponding to the allocated resource in the UL grant or the DL assignment received by the user terminal on the PDCCH channel Information, and according to the broadcast channel or dedicated channel from the base station 1, obtain the CC index information and the mapping relationship between the CC index and the frequency, and obtain the CC index corresponding to the frequency resource allocated in the UL grant or the DL assignment, and because The CC index has a certain correspondence with the UL grant or the DL assignment. Therefore, according to the CC index, the user terminal 1 can determine the order identifier of the UL grant or the DL assignment. Of course, the correspondence between the CC index and the UL grant or the DL assignment order can be configured according to different wireless communication systems, and the base station 1 needs to notify the user terminal 2 of the configuration information in advance.

When the base station 1 and the user terminal 2 determine the order identifier of the resource allocation indication information in a dynamic manner, that is, at this time, the user terminal 2 already knows whether to use the size information according to the resource block or according to the modulation and coding method or The combination of the two determines the order identifier of the resource allocation information, and accordingly, the user terminal 2 determines the order identifier of the resource allocation indication information in a corresponding manner. The process of determining is consistent with the determination method adopted by the base station 1 and therefore will not be described herein.

Then, the following information is taken as an example to specifically describe the order information of the resource allocation indication information by the user terminal 2.

In step S26, the user terminal 2 identifies that the received data in each transport block from the base station 1 is decapsulated according to a predetermined rule according to the order of each resource allocation indication information. For example, the user terminal 2 knows that the base station 1 encapsulates the service data in the transport block indicated by the DL assignment with the lowest number, for example, the TB 1 indicated by the DL assignment 1, and then encapsulates the remaining service data in the second smallest number. In the transport block indicated by the DL assignment, for example, the order in the TB 2 indicated by the DL assignment 2 encapsulates the service data, and therefore, the user terminal 2 decapsulates the data in each transport block according to the order, for example First, the TB 1 indicated by the DL assignment 1 is decapsulated first, and then the TB 2 indicated by the DL assignment 2 is decapsulated. Of course, the order of the above decapsulation is only an example, and those skilled in the art can understand that for multiple TBs, they can also be decapsulated in parallel or sequentially decapsulated in other orders. If a high-level data packet, such as an RRC PDU, is encapsulated in at least two TBs respectively, for example, one RRC PDU is segmented in TB1 and TB2, because the user terminal 2 is based on the information in the DL assignment, in the user terminal 2 The receiver knows the order of TB1 and TB2, so user terminal 2 can jointly process the last segment of TB1 (if present) and the first segment of TB2 (if present) to obtain the original packet. The above method is also applicable to the case where one RRC PDU is separately encapsulated in two or more TBs.

The following line of data is used as an example to describe the synchronization of the order information of the resource allocation indication information between the base station 1 and the user terminal 2. Hereinafter, the above data transmission is taken as an example to allocate resources between the base station 1 and the user terminal 2. A brief description of the synchronization of the order information of the information is indicated. In another embodiment, for the uplink data, after the user terminal 2 determines the order identifier of each resource allocation indication information according to each resource allocation indication information in step S25, the user terminal 2 according to each resource in step S27. The order indicator of the allocation indication information encapsulates the user data in each transport block corresponding to each resource allocation indication information according to a predetermined rule, and the process of the encapsulation is similar to step S22 of the base station 1 end, and is not described herein, and then The user terminal 2 transmits the encapsulated transport block to the base station 1.

Then, in step S28, the base station 1 de-encapsulates the received data in each transport block from the user terminal 2 according to the order of each resource allocation indication information. Since the resource allocation indication information is generated by the base station 1, the base station 1 knows the order identifier of the UL grant. Therefore, the base station 1 directly identifies the received uplink data from the user terminal 2 according to the order identification.

In the above embodiment, for convenience of description, the downlink data transmission is described first, that is, step S26; then the uplink data transmission is described, that is, step S27 and step S28. Those skilled in the art can understand that there is no obvious sequence between the uplink data transmission and the downlink data transmission, and therefore the sequence numbers of the above steps do not indicate the order of actual execution.
