Method and apparatus for extending coverage in communication system

說明書
Meanwhile, when an RRC connection between the terminal and the base station is configured or an RRC connection between the terminal and the base station is deactivated, the terminal may perform a PDSCH reception operation or a PUSCH transmission operation based on a received fallback DCI. Here, the PDSCH may be repeatedly received. This operation has been described in Method 4.2-1 and the like. In addition, a PUCCH including a HARQ-ACK for the PDSCH may be repeatedly transmitted. This operation has been described in Method 4.3-4, Method 4.3-5, and Method 4.3-6. Also, the PUSCH may be repeatedly transmitted. This operation has been described in Methods 4.1-7.
4.5 Frequency Resource Interpretation Method and Coherence Application Method
In an initial access procedure, a terminal may perform a separate RA procedure. For example, a base station may inform the terminal of the number of repetitions of a Msg3 PUSCH by using a UL grant belonging to a MAC RAR or a separate UL grant. The terminal may identify the number of repetitions of the Msg3 PUSCH based on the UL grant received from the base station, and may repeatedly transmit the Msg3 PUSCH to the base station.
