說明書
The TDRA list included in pucch-configCommon may be utilized by a DCI of other scenarios as well as the RAR UL grant. For example, even when a DCI format 0_0 (e.g., cyclic redundancy check (CRC) of the DCI format 0_0) is scrambled with C-RNTI, MCS-C-RNTI, CS-RNTI, or TC-RNTI, the TDRA list referenced by the terminal may include the TDRA index indicating repeated transmission of the PUSCH (e.g., the number of PUSCH repetitions). The TDRA table referenced by the TDRA index included in the DCI (e.g., DCI format 0_0) may include information indicating the number of PUSCH repetitions (e.g., Msg3 or MsgA). These methods will be described in detail in the exemplary embodiments below.
When the PUSCH is repeatedly transmitted, the size (e.g., TB size) of the PUSCH (e.g., PUSCH message) may be derived by using an MCS, time resource, and/or frequency resource indicated by the MAC RAR (or fallback RAR). Alternatively, the size of the PUSCH may be indicated (e.g., configured) to the terminal by higher layer signaling.
