Abstract:
Approaches for performing Physical Uplink Shared Channel (PUSCH) transmissions include receiving, by a user equipment (UE) from a base station, an indicator of a plurality of precoders corresponding to M Physical Uplink Shared Channel (PUSCH) repetitions, wherein M is an integer. A plurality of precoders corresponding to two or more of the M PUSCH repetitions are indicated. The UE configures the plurality of precoders based on the indicator and transmits one or more of the M Physical Uplink Shared Channel (PUSCH) repetitions corresponding to one or more of the plurality of precoders. The indicator can be provided in higher layer signaling. One or more transmission rank indicator (TRIs) and transmission precoder matrix indicators (TPMIs) for the M PUSCH repetitions can be provided. The indicator can be provided in a scheduling downlink control indicator (DCI) communication. The indicator can also be provided within N sounding reference signal (SRS) resource indicator(s) (SRIs) of the scheduling DCI.
