Abstract: Apparatus, methods, and computer-readable media for facilitating UE indication of null tone placement for demodulation are disclosed herein. An example method for wireless communication at a UE includes measuring one or more downlink transmissions in one or more frequency subcarriers received from a base station over a time period. The example method also includes transmitting, to the base station, a null tone indication indicating one or more locations for one or more null tones, the one or more locations for the one or more null tones based at least in part on measurements performed on the one or more downlink transmissions received over the time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message associated with an uplink transmission from one or more antenna panels. In some cases, the control message may include a first indication associated with an uplink transmission configuration indicator and a second indication of an uplink power control parameter set identifier associated with the first indication. In some cases, the control message may include a bit, where a value of the bit indicates whether an uplink transmission configuration indicator is included in the control message or an uplink power control parameter set identifier is included in the control message. The UE may then communicate with the base station based on receiving the control message.

Abstract: This disclosure provides systems, methods and apparatus for aperiodic measurement configurations. In one aspect, delaying transitioning of a secondary cell group (SCG) to an active state until a next synchronization signal block (SSB) or periodic reference signal may result in an excessive delay in obtaining network resources of the SCG. Some aspects described herein enable a base station (BS) to transmit signaling using a master cell group (MCG) cell to schedule resources for an aperiodic reference signal transmission and measurement using the SCG. For example, the BS may transmit signaling to a user equipment (UE) to identify a reference signal resource for an aperiodic reference signal transmission and measurement. In this case, the BS may transmit the aperiodic reference signal using an SCG cell, and the UE may measure the aperiodic reference signal and provide a report identifying the measurement of the aperiodic reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) scheduling a physical downlink shared channel (PDSCH). The UE may transmit a physical uplink control channel (PUCCH) based on a PUCCH repetition factor, wherein the PUCCH repetition factor is indicated by a location of a control channel element (CCE) of the PDCCH, a PUCCH resource indicator (PRI) bitfield of the PDCCH, and at least one of: one or more parameters of the PDCCH, or one or more parameters of the PDSCH. Numerous other aspects are provided.

Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may inform a base station of multiple transmission-antenna switching capabilities supported by the UE. The supported transmission-antenna switching capabilities may include a first transmission-antenna switching capability and a second transmission-antenna switching capability. The UE may receive a message that triggers the UE to switch from using a first configuration associated with the first transmission-antenna switching capability to using a second configuration associated with the second transmission-antenna switching capability. The UE may perform a sounding procedure using the second configuration associated with the second transmission-antenna switching capability based on receiving the message.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes receiving, from a network entity, signaling that schedules an uplink or downlink transmission on resources that overlap with a time gap for switching from a first set of frequency resources to a second set of frequency resources; and taking an action to process the uplink or downlink transmission so that the uplink or downlink transmission does not overlap with the time gap.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH. The UE and/or the network node may determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment table for a subcarrier spacing associated with the communication. Numerous other aspects are described.
