Summary of the invention

In the existing LTE system, in one transmission time interval, only one transport block is used for uplink or downlink data transmission. Therefore, data to be transmitted is directly encapsulated in the data block, and then subsequent transmission processing is performed.

The allocation of the blocks, 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 according to a predetermined rule for the downlink data. In each transport block, for uplink data, the received data in each transport block from the user terminal is decapsulated according to a predetermined rule, and in order to maintain synchronization with the user terminal, the base station also needs to reserve the resource.

FIG. 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. The base station 1 and the user terminal 2 may further include a relay station and the like as needed. The intermediate device is omitted in 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 four component carrier bandwidths are all configured to be 20M. It can be understood that the base station configures no more than five component carriers for one user terminal.

Figure 2 illustrates 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, where the resource allocation indication information is used to indicate related information of resources allocated to the user terminal 2, that is, on each component carrier. Each of the UL grants includes a resource allocation indication information, that is, a UL grant or a DL assignment, and 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 terminated resource block. The sequence number, and the modulation and coding method corresponding to the allocated resource block. The DL assignment includes resource information allocated for transmitting downlink data to the user terminal 2 by the base station 1, such as the sequence number of the allocated start resource block and the sequence number of the terminated resource block, and the modulation and coding corresponding to the allocated resource block. the way.

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 allocation indication. The order of the information is identified, and the data is sequentially encapsulated in a transport block indicated by each of the resource allocation indication information identified by the different order according to a predetermined rule. Similarly, for uplink data from the user terminal 2, when the base station 1 receives multiple transmissions from the user terminal 2 At the time of the block, the base station 1 also needs to know the order identification of each transport block, and decapsulate the data from the user terminal 2 according to a predetermined rule.

Therefore, in step S21, the base station 1 determines the order identification of each resource allocation indication information based on each resource allocation indication information. In the following, the method for numbering the resource allocation indication information by the base station 1 is specifically described by using two specific implementation manners.

> 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 resource allocation indication information corresponding to CC4 The number is 4. In another embodiment, if the user terminal 2 is configured with 3 CCs, for example, CC1, CC3, and CC5, respectively, the resource allocation indication information corresponding to the CC1 is 1 and the resource allocation indication corresponding to the CC3. 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 number of resource allocation indication information corresponding to CC1 may be 4, and the number of resource allocation indication information corresponding to CC2 is 3, corresponding to CC3. The number of the resource 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 - corresponding, the order identification of the resource allocation indication information can be conveniently determined in this manner.

> Dynamic mode

In addition to the 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.

Since the resource allocation indication information includes the size information of the resource block allocated to the user terminal and the modulation and coding mode, 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 When the station 1 sorts the size of the resource block, the resource allocation indication information indicating that the user terminal 2 is allocated the largest resource block may be numbered 1, and the resource allocation indication information number indicating that the user terminal 2 is allocated the next largest resource block. 2, and so on. If the base station 1 sorts the resource allocation indication information according to the modulation and coding mode adopted by the resource block, for example, the base station 1 may number the resource allocation indication information indicating that the resource block adopts the high-order modulation and coding mode to 1, and the order is higher. Low, the number is larger. For example, for the resource allocation indication information indicating that 64QAM, 16QAM, and QPSK are respectively used, the base station 1 numbers the resource allocation indication information indicating that the modulation and coding mode is 64QAM to 1, and the resource allocation indication information number indicating that the modulation and coding mode is 16QAM. 2, the resource allocation indication information indicating that the modulation and coding mode is QPSK is numbered 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 the 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 also be sorted according to the resource block size according to the order of the modulation and coding modes. This dynamic approach eliminates the need for additional signaling 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, the static or semi-static mode is required, that is, the base station 1 is based on The order identification of the component carriers determines the order identification of each resource allocation indication information corresponding to each component carrier.

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 the resource allocation information is determined 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 in accordance with 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. First, the following line data is taken as an example for explanation. For 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 transmitted data amount, and the minimum transmitted data amount represents a lower limit of the amount of data for transmitting the service, and therefore, the predetermined The rules include: 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 remaining service of the highest priority service Data is repackaged into the transport block, and then, if the transport block indicated by the DL assignment numbered 1 is already full, the remaining data of the highest priority service is repackaged to the DL assignment numbered 2 In the transport block, and so on, the flow of the logical channel priority is optimized. Of course, the predetermined rule may also be: The base station 1 first encapsulates the lowest transmission data amount of each service in the transport block indicated by the DL assignment numbered 4, if the transport block has remaining resources, Transmitting the remaining data of the highest priority service into the transport block, and then, if the transport block indicated by the DL assignment number 4 is already full, the remaining data of the service with the highest priority is re Encapsulation into the transport block indicated by the DL assignment numbered 3, and so on, optimizes the flow of the logical channel priority.

Then, in step S23, the base station 1 notifies the user terminal 2 of the resource allocation indication 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 can understand that there is no obvious order 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, to notify the user terminal 2, for example, CC1, CC2, CC3, and CC4. The base station 1 may 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 The high-level control information, such as a Radio Resource Control (RRC) or a medium access control layer control message, is used for transmission.

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 may transmit the CC index information and the corresponding relationship by using a broadcast channel, such as a physical downlink shared channel or a physical broadcast channel, or the base station 1 may use a dedicated channel, for example, using high layer control information, such as a radio resource control message or a medium access control layer. The message transmits 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 identification of each resource allocation indication information based on each resource allocation indication information.

For example, the base station 1 transmits a UL grant message on the DL CC of the PDCCH channel, and the user terminal according to the DL CC and the System Information Block 2 (SIB2), the SIB2 includes the uplink and the downlink. For the corresponding relationship, the user terminal 2 can obtain 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 to which the UL grant or DL assignment acts.

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 by using the configuration information of the upper layer, and of course, adopts static or dynamic The method may also be that the system has been configured in advance, and therefore, the base station 1 is not required to notify the user terminal 2 by signaling.

When the user terminal 2 knows that the sequence identification of the resource allocation indication information is synchronized with the base station 1 in a static manner, the frequency information 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 is used. And obtaining a CC index letter based on a broadcast channel or a dedicated channel from the base station 1. And the mapping between the CC index and the frequency, obtaining 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, 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 mode or The combination of the two determines the order identification of the resource allocation information, and accordingly, the user terminal 2 determines the order identification of the resource allocation indication information in a corresponding manner. The process of determining is consistent with the determination of the use of the base station 1 and, therefore, will not be described herein.

Then, the following line data 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 first encapsulates the service data in the transport block indicated by the DL assignment with the lowest number, for example, TB1 indicated by 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 in this order, for example, First, TB 1 indicated by DL assignment 1 is decapsulated, and TB 2 indicated by 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 higher layer data packet, for example, an RRC PDU, is separately encapsulated in at least two TBs, for example, one RRC PDU is segmented in TBI and TB2, because the user terminal 2 is in the user terminal 2 according to the information in the DL assignment The receiver knows TBI and TB2 The order, therefore, user terminal 2 can jointly process the last segment of the TBI (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 RC PDU is separately packaged in two or more TBs.

The following line 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 used as an example to allocate resource indication information between the base station 1 and the user terminal 2. The synchronization of the order information is briefly explained. 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 of the allocation indication information is to encapsulate the user data in each of the transport blocks corresponding to each of the resource allocation indication information according to a predetermined rule. The process of the encapsulation is similar to the step S22 of the base station 1 and is not described herein. The user terminal 2 transmits the encapsulated transport block to the base station 1.

Then, in step S28, the base station 1 decapsulates the received data in each transport block from the user terminal 2 according to a predetermined rule according to the secondary identification 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 explanation, the downlink data transmission is first described, that is, step S26; and 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.
