Detailed ways

Fig. 1 shows a wireless network system composed of a base station 1 and a user terminal 2 according to a specific embodiment of the present invention, wherein the base station 1 and the user terminal 2 may also include equipment such as relay stations as required, for the convenience of description, Fig. 1 omits the intermediate equipment, and only shows the base station 1 and the user terminal 2. Among them, the user terminal 2 is configured with four component carriers, namely CC1, CC2, CC3, and CC4. The bandwidth of the above-mentioned component carriers can vary according to different application scenarios, and the size of each carrier does not exceed 20M. In this embodiment , the bandwidth of the four component carriers is configured as 20M. It can be understood that the base station configures no more than five component carriers for a user terminal.

Fig. 2 shows a system flow chart according to a specific 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 information about resources allocated to the user terminal 2, that is, each component carrier Each corresponds to a resource allocation indication information, that is, UL grant or DL assignment. The UL grant includes the resource information allocated for the user terminal 2 to transmit uplink data to the base station 1, such as the sequence number of the allocated starting resource block and the terminated resource block. , and the modulation and coding schemes corresponding to the allocated resource blocks. The DL assignment includes the resource information allocated for the base station 1 to transmit downlink data to the user terminal 2, such as the sequence number of the allocated starting resource block and the sequence number of the ending resource block, as well as the modulation and coding corresponding to the allocated resource block Way.

For downlink data transmission, in order to effectively encapsulate the data in the transport block (Transport Block, TB) indicated by the resource allocation indication information, 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 the transmission blocks indicated by the resource allocation indication information with different order identifications according to predetermined rules. Similarly, for uplink data from user terminal 2, when base station 1 receives multiple transport blocks from user terminal 2, base station 1 also needs to know the sequence identification of each transport block, and The data is decapsulated.

Therefore, in step S21, the base station 1 determines the sequence identifier of each resource allocation indication information according to each resource allocation indication information. Hereinafter, the method for numbering the resource allocation indication information by the base station 1 will be specifically described through two specific implementation manners respectively.

static or semi-static

The base station 1 may determine the sequence identifier of each piece of resource allocation indication information corresponding to each component carrier according to the sequence identifier of the component carriers, that is, the serial 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, the number of resource allocation indication information corresponding to CC3 is 3, and the number of 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, such as CC1, CC3 and CC5 respectively, the number of the resource allocation indication information corresponding to CC1 is 1, and the resource allocation indication information corresponding to CC3 The number of the information is 2, and the number of the resource allocation indication information corresponding to CC5 is 3. Of course, the above method is only an example, and those skilled in the art can understand that the number of resource allocation indication information corresponding to CC1 is 4, the number of resource allocation indication information corresponding to CC2 is 3, and the resource allocation indication information corresponding to CC3 The number of the allocation indication information is 2, and the number of the resource allocation indication information corresponding to CC4 is 1 to determine the number of the resource allocation indication information. Because there is a one-to-one correspondence between the component carrier and the resource allocation indication information, the sequence identification of the resource allocation indication information can be conveniently determined in this way.

dynamic way

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

Since the resource allocation indication information includes the size information and the modulation and coding mode of the resource blocks allocated to the user terminal, base station 1 can also sort the resource allocation indication information according to the resource block size and/or the modulation and coding mode. For example, if the base station 1 sorts the resource blocks according to the size of the resource blocks, the resource allocation indication information indicating that the user terminal 2 is allocated the largest resource block can be numbered as 1, and the resource allocation indicating that the user terminal 2 is allocated the second largest resource block The instruction number is 2, and so on. If the base station 1 sorts the resource allocation indication information according to the modulation and coding methods adopted by the resource blocks, for example, the base station 1 can number the resource allocation indication information indicating that a high-order modulation and coding mode is used for the resource blocks as 1, and the higher the order The lower the number, the higher the number. For example, for the resource allocation indication information respectively indicating the use of 64QAM, 16QAM and QPSK, base station 1 will number the resource allocation indication information indicating that the modulation and coding mode is 64QAM as 1, and number the resource allocation indication information indicating that the modulation and coding mode is 16QAM is 2, and 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 may sort the resource allocation indication information in combination with the allocated resource block size and the modulation and coding mode in the resource allocation indication information. For example, the resource allocation indication information is first sorted according to the resource block size, and if the resource block sizes indicated by each resource allocation indication information are the same, the resource allocation indication information is sorted according to the order of modulation and coding modes. Of course, the resource allocation indication information may also be sorted according to the order of the modulation and coding modes first, and then according to the size of the resource block. This dynamic method does not require additional signaling overhead and saves bandwidth resources. However, there may be a situation where the size of the resource blocks indicated by each resource allocation indication information is the same, and the modulation and coding methods adopted are also the same. The sequence identifier of the component carrier determines the sequence identifier 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 rules of how to determine the sequence 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 method or a combination of the two Order ID.

Because the base station 1 generates the resource allocation information, the base station 1 knows the order identifiers of the resource allocation indication information.

Then, in step S22, base station 1 encapsulates user data in each transport block corresponding to each resource allocation indication information according to the order identification of each resource allocation indication information and according to predetermined rules, and sends it to user terminal 2. First, the following data is taken as an example for description. For downlink data, for example, when the base station 1 has multiple services to be sent to the user terminal 2, each of the services includes the minimum amount of data to be sent, and the minimum amount of data to be sent represents the lower limit of the amount of data transmitted for the service. Therefore, the predetermined The rules include: base station 1 first encapsulates the minimum amount of data to be sent by each service in the transmission block indicated by the DL assignment numbered 1, and if there are remaining resources in the transmission block, then the remaining resources of the service with the highest priority The data is repackaged into the transmission block, and then, if the transmission block indicated by the DL assignment numbered 1 is already occupied, the remaining data of the service with the highest priority is repackaged into the DL assignment numbered 2 In the transmission block, and so on, so as to optimize the process of logical channel priority. Of course, optionally, the predetermined rule may also be: base station 1 first encapsulates the minimum amount of data to be sent by each service in the transport block indicated by the DL assignment numbered 4, if there are remaining resources in the transport block, Then re-encapsulate the remaining data of the service with the highest priority into the transmission block, and then, if the transmission block indicated by the DL assignment numbered 4 is already occupied, then repackage the remaining data of the service with the highest priority Encapsulated into the transmission block indicated by the DL assignment numbered 3, and so on, thereby optimizing the process of 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 (Physical Downlink ControlChannel, PDCCH). Those skilled in the art can understand that there is no obvious sequence between step S22 and step S23.

In another embodiment, the base station 1 also needs to notify the user terminal 2 of the order identifier of each component carrier, that is, the CC Index, for example, CC1, CC2, CC3 and CC4. The base station 1 may use a broadcast channel, such as a Physical Downlink Shared Channel (Physical Downlink Shared CHannel, PDSCH) or a Physical Broadcast Channel (Physical Broadcast Channel, PBCH) to send the CC index information, or use a dedicated channel, such as using high-level control information, such as radio resource control Message (Radio Resource Control, RRC) or media access control layer control message for transmission.

In another embodiment, the base station 1 notifies the user terminal 2 of the order identifier of each component carrier and the correspondence between the component carrier and the frequency point. Base station 1 can use a broadcast channel, such as a physical downlink shared channel or a physical broadcast channel to send the CC index information and the corresponding relationship, or base station 1 can use a dedicated channel, such as using high-level control information, such as radio resource control messages or medium access control layer control The message transmits the CC index information and the corresponding relationship.

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

Then, in step S25, the user terminal 2 determines the sequence identifier of each resource allocation indication information according to each resource allocation indication information.

For example, base station 1 sends a UL grant message on the DL CC of the PDCCH channel, then the user terminal according to the DL CC and the system information block 2 (System Information Block, SIB2), the SIB2 contains the information between the uplink and the downlink Corresponding relationship, the user terminal 2 can obtain the component carrier on which the UL grant acts; in addition, when the PDCCH contains a carrier indication field (Carrier Indication Field, CIF), the user terminal 2 can also obtain the component carrier in the PDCCH according to the information in the CIF Component carrier for UL grant or DL assignment.

In addition, the user terminal 2 knows in advance whether to use a static or dynamic method to obtain the sequence identifier of the resource allocation indication information. For example, the base station 1 notifies the user terminal 2 of the method through the high-level configuration information. Of course, a static or dynamic method is used. The way may also be that the system has been pre-configured, so there is no need for the base station 1 to notify the user terminal 2 through signaling.

When the user terminal 2 knows the sequence identifier of the resource allocation indication information synchronized with the base station 1 in a static manner, the user terminal receives the frequency information of the component carrier corresponding to the resource allocated in the UL grant or DL assignment received on the PDCCH channel, And according to the broadcast channel or dedicated channel from the base station 1, the CC index information and the mapping relationship between the CC index and the frequency are obtained, and the CC index corresponding to the frequency resources allocated in the UL grant or DL Assignment is obtained, and because the CC index and the UL There is a certain correspondence between the grant or the DL assignment, therefore, according to the CC index, the user terminal 1 can determine the sequence identifier of the UL grant or the DL assignment. Of course, the corresponding relationship between the CC index and the UL grant or 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 sequence 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 resource block size information or the modulation and coding method or both. The combination of the two determines the sequence identifier of the resource allocation information, therefore, correspondingly, the user terminal 2 determines the sequence identifier of the resource allocation instruction information in a corresponding manner. The determination process is consistent with the determination method adopted by the base station 1 side, so details will not be described here.

Then, the downlink data is taken as an example first, and the sequence information of using the resource allocation instruction information by the user terminal 2 is described in detail.

In step S26, the user terminal 2 decapsulates the received data in each transport block from the base station 1 according to the order identification of each resource allocation indication information according to a predetermined rule. For example, user terminal 2 knows that base station 1 first encapsulates the service data in the transport block indicated by the DL assignment with the smallest number, such as TB1 indicated by DL assignment1, and then encapsulates the remaining service data in the transport block indicated by the next-lowest DL assignment. In the indicated transmission block, for example, the order in TB2 indicated by DL assignment2 encapsulates the service data, therefore, the user terminal 2 decapsulates the data in each transmission block according to this order, for example, first decapsulates DL assignment1 The indicated TB1, then decapsulates the TB2 indicated by DL assignment2. Certainly, the above order of decapsulation is only an example, and those skilled in the art can understand that for multiple TBs, decapsulation may also be performed in parallel, or sequentially in other orders. If a high-level data packet, such as RRC PDU is encapsulated in at least two TBs, for example, an RRC PDU is segmented in TB1 and TB2, then because user terminal 2 is based on the information in the DL assignment, the user terminal 2 The receiver knows the order of TB1 and TB2, so UE 2 can jointly process the last segment of TB1 (if present) and the first segment of TB2 (if present) to obtain the original data packet. The above method is also applicable to the situation where one RRC PDU is encapsulated in two or more TBs.

The above downlink data is taken as an example to describe the synchronization of the sequence information of the resource allocation indication information between the base station 1 and the user terminal 2. In the following, the resource allocation indication information between the base station 1 and the user terminal 2 is described by taking the uplink data transmission as an example. Synchronization of sequence information is briefly explained. In another embodiment, for uplink data, after user terminal 2 determines the order identifier of each resource allocation indication information according to each resource allocation indication information in step S25, in step S27, user terminal 2 The sequence identification 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. The encapsulation process is similar to step S22 at the base station 1 side, and will not be described in detail here. Then, User terminal 2 sends the encapsulated transport block to 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 the sequence identification of each resource allocation indication information and according to predetermined rules. Because the resource allocation indication information is generated by the base station 1, the base station 1 knows the order identification of the UL grant, so the base station 1 decapsulates the received uplink data from the user terminal 2 directly according to the order identification.

In the above embodiments, for the convenience of description, the downlink data transmission is described first, 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, so the sequence numbers of the above steps do not indicate the actual execution sequence.
