Ultra-Reliability Design for Physical Uplink Control Channel (PUCCH) in 5th Generation (5G) New Radio (NR)

摘要

A mobile station and base station are presented where RRC messages are used for configuring a number of repetitions in a time domain for a PUCCH format 0. If a first number of repetitions has been previously configured, the UCI is repeatedly transmitted in continuous symbols based on the first number of repetitions. RRC messages can also be used to enable frequency hopping in a frequency domain for the PUCCH format 0, where the number of repetitions in the time domain is applied per hop in the frequency domain. Otherwise, RRC messages may include transmission power parameters whose selection is responsive to the type of RNTI used for scheduling PDSCH communications. A first set of parameters is used if a C-RNTI is used for scheduling the PDSCH, and a second set is used when a RNTI, different from a C-RNTI, is used for scheduling of the PDSCH.
