DETERMINING UPLINK CONTROL CHANNEL REPETITION FACTORS

Abstract:

Methods, systems, and devices for wireless communications are described. Generally, a base station may implicitly indicate a physical uplink control channel (PUCCH) repetition factor for a user equipment (UE) to use on a next PUCCH via the selection of an aggregation level for the preceding physical downlink control channel (PDCCH). For example, the base station may configure relationships between PUCCH repetition factors and aggregation levels. To determine which PUCCH repetition factor the UE should use, the base station may select the corresponding aggregation level, and may transmit a downlink control message (e.g., a downlink control information (DCI) message) on a PDCCH using the selected aggregation level that corresponds to the desired PUCCH repetition factor.
