Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A first message can be transmitted, in an inactive or idle state, a on a physical random access channel, where the first message includes a random access preamble. A second message can be received on a downlink channel in response to the first message, where the second message includes a temporary cell radio network temporary identifier and an uplink grant for the user equipment. A request can be transmitted on an uplink channel based on the uplink grant. A common search space of a downlink control channel can be monitored, such as for an acknowledgement message or a negative acknowledgement message corresponding to the request and identifiable based on the temporary cell radio network temporary identifier.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to interpreting a timing advance (TA) command for members of a timing advance group (TAG), such as different uplink component carriers and/or different bandwidth parts, having different numerologies, such as different subarrier spacing (SCS). A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a TA command. The UE interprets the TA command differently for different members of a same TAG, associated with different numerologies. The UE applies a timing adjustment when transmitting an uplink transmission to the BS based, at least in part, on the interpretation.

Abstract: The present disclosure describes a method, an apparatus, and a computer readable medium for managing handovers at a base station. For example, the method may include receiving a request for STX to one or more connected user equipments (UEs), identifying whether one or more conditions have to be satisfied prior to initiating of the STX, and determining whether the one or more conditions are satisfied. The example method further includes initiating the STX at the base station in response to the identifying and the determining and performing a corrective action for managing the handovers in response to the initiating of the STX.

Abstract: Aspects of the present disclosure provide apparatus and techniques to enhance mobility of single receive (RX) devices. An exemplary method generally includes searching for synchronization signals transmitted by one or more cells while performing one or more mobility procedures and taking one or more actions to enhance detection of synchronization signals, wherein the one or more actions taken depend, at least in part, on a type of mobility procedure performed.
