Rate-matching, puncturing, and power scaling uplink communications in full duplex mode
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust a transmission parameter, associated with an uplink transmission from the UE, such that a phase for the uplink transmission is continuous across symbols of the uplink transmission. Adjusting the transmission parameter includes at least one of: rate-matching, puncturing, or power scaling one or more of the symbols within the uplink transmission, modifying at least one of a modulation and coding scheme or a power associated with a downlink transmission to the UE, or a combination thereof. The UE may further transmit, to a base station, the uplink transmission based at least in part on adjusting the transmission parameter. Numerous other aspects are provided.
