Embodiment 1
[0053] This embodiment proposes a method for encoding uplink control information based on PUSCH transmission. Currently, two transmission blocks are configured, and both transmission blocks have uplink data transmission, and two codeword streams are obtained after encoding. The uplink control information is ACK / NACK information or RI information.
[0054] Such as Figure 4 As shown, the method of this embodiment includes:
[0055] Step 410, the user equipment (UE) selects a transport block from two transport blocks;
[0056] The UE can select a transport block from two transport blocks in one of the following ways:
[0057] (1) The UE selects the modulation and coding index in the two transport blocks A smaller transport block, if the modulation and coding indexes of the two transport blocks are the same, select a transport block arbitrarily or select a default transport block;
[0058] (2) The UE compares the sum of the bits of each code block obtained after two transpor...
example 1
[0086] The application scenarios and related parameters of this example are as follows:
[0087] Assume that the uplink transmission is based on the conventional CP, that is, there are 14 SC-FDMA symbols in the subframe, 2 symbols are used to send DMRS, and the number of transmission blocks for uplink transmission is 2 at the same time. The two transmission blocks are channel coded and After rate matching and other operations, the corresponding codeword streams are mapped to two-layer transmission. In the uplink transmission, there is no SRS to be sent, and the UE has data information to be sent, and at the same time, 2-bit ACK / NACK information and 2-bit RI information need to be sent, so that ACK / NACK information, RI information and uplink data information are multiplexed on the PUSCH for transmission.
[0088] Assuming that the UE obtains from the information in DCI format 0 that the bandwidth allocated by the base station for PUSCH transmission is 1 resource block (RB), and...
example 2
[0093] The application scenario and various parameters of this example are the same as those in Example 1 of Embodiment 1.
[0094] In this example, in step 410, the UE selects the corresponding Larger one transfer block. Since the number of code blocks for each transport block is C 0 = 1, C 1 = 1, the code block size is Therefore, the transport block whose index is 1 is selected, which is called the second transport block.
[0095] The corresponding calculation formula adopted in step 420 is:
[0096]
[0097] According to the previous analysis, O=2 in the above formula, In this way, the target number of coded symbols Q' when the ACK / NACK information is transmitted on each transport layer can be calculated from the above formula ACKperlayer =5,Q ACKperlayer =10; in the same way, the number of target coding symbols Q' when the RI information is transmitted on each transmission layer is obtained RIperlayer =5,Q RIperlayer =10.
