WIPO Patent Application WO/2021/207963

A1

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal mapping each of a plurality of receive port identifiers of the UE to at least one repetition of a multi-repetition downlink transmission, wherein different receive port identifiers are mapped to different repetitions of the multi-repetition downlink transmission. The UE may transmit, based at least in part on the mapping, one or more uplink reference signals using transmission ports corresponding to each receive port identifier that is mapped to at least one repetition of the multi-repetition downlink transmission. The UE may receive the multi-repetition downlink transmission according to the mapping and based at least in part on the one or more uplink reference signals.
