The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof.

The UE may transmit a power headroom report in an uplink transmission to the base station, the power headroom report indicating the calculated available power headroom. The base station may schedule one or more uplink messages at the UE according to the available power headroom.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first uplink transmission using a first transmit power that is based at least in part on: a first power level associated with the first uplink transmission, and a power scaling factor based at least in part on a power offset. The UE may transmit, to the network node, a second uplink transmission, at least partially overlapping in time with the first uplink transmission, using a second transmit power that is based at least in part on: a second power level associated with the second uplink transmission, a maximum available transmit power, and the first transmit power. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a frequency hopping configuration for repetitions of an uplink message that are to be transmitted via a set of resources, including one or more resources that support full-duplex communications. The UE may determine that some resources of the set of resources are available for transmitting the repetitions in a time domain. The UE may use a frequency hopping pattern to transmit the uplink message and the repetitions of the uplink message, where the frequency hopping pattern may include two or more frequency hops and based on the available resources and the frequency hopping configuration. In some cases, the UE may determine that some resources of the set of resources are unavailable in a frequency domain, and as such, the UE may drop respective transmissions of the uplink messages on the unavailable resources.
