Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message, the UE capability message indicating a supported transmit antenna switching (TxAS) capability for each port of the UE. The UE may receive a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration for the UE, the UL MIMO configuration being based at least in part on the UE capability message. The UE may identify, based at least in part on the configuration message, a sounding reference signal (SRS) configuration to use for transmitting SRSs in conjunction with the UL MIMO communications, the SRS configuration comprising a configuration for transmission by the UE of SRSs using at least one of the two or more ports of the UE, the SRSs transmitted on one or more antennas of the UE selected according to a TxAS configuration for the respective port.

Abstract: 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.

Abstract: Aspects of the present disclosure provide techniques for managing unwanted transmissions by a wireless communications device, such as spurious transient transmissions caused by changing a power level of a transmitter. An exemplary method includes determining, based on one or more parameters, an action to reduce an impact of a spurious transmission by the UE, wherein the spurious transmission relates to at least one of changing a transmit power level at the UE or switching one or more radio components at the UE, and taking the determined action to reduce the impact.

Abstract: This disclosure provides systems, methods and apparatuses for switching configurations for uplink transmission switching. A user equipment (UE) may receive, from a network entity such as a base station, a switching configuration for an uplink transmission switching for three or more carriers. The switching configuration may be associated with switching one or more uplink transmission chains of the UE from or to one or more carriers of the three or more carriers within a time period. The switching configuration may be associated with a UE capability. The switching configuration may permit switching from or to one carrier within the time period associated with the UE capability. The switching configuration may permit switching from or to two carriers within the time period associated with the UE capability. The switching configuration may depend on the UE capability, thereby not causing the uplink transmission switching to degrade a performance of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may calculate a minimum distance between a first resource block included in a transmission bandwidth and a resource block corresponding to a starting point of another transmission bandwidth, the minimum distance between the first resource block included in the transmission bandwidth and the resource block corresponding to the starting point of the other transmission bandwidth being equal to a sum of a region modification parameter and a largest value of a plurality of values, the plurality of values including one and a highest integer that is less than or equal to half of a quantity of contiguous resource blocks included in the other transmission bandwidth. The UE may communicate using a power enhancement that is in accordance with the minimum distance. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.
