Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a time domain window (TDW) configuration including a start time of a TDW and a length of the TDW, where the TDW is a duration over which a network entity is scheduled to perform joint channel estimation. The UE may receive a timing advance (TA) command during the TDW indicating a TA value to apply to signaling. The UE may transmit the signaling in accordance with the TA value or independent of the TA value based on the UE prioritizing the TA adjustment or maintaining power consistency and phase continuity for DMRS bundling, respectively. The UE may determine whether to prioritize the TA adjustment or DMRS bundling for the joint channel estimation based on one or more parameters satisfying criteria.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) carrying information indicating an updated configuration for the UE, wherein the DCI is associated with a hybrid automatic repeat request (HARQ) process for which HARQ feedback regarding the DCI is disabled. The UE may transmit the HARQ feedback regarding the DCI based at least in part on the DCI carrying the information indicating the updated configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive, at a source cell served by a network entity, signaling that triggers a handover to a target cell. The UE may also receive a first set of parameters associated with the target cell, the first set of parameters indicating that the target cell is served by the network entity. The UE may then transmit, to the target cell, an uplink communication in accordance with a timing advance value for the target cell. In some examples, the timing advance value for the target cell may be derived using a timing advance value for the source cell based on the target cell being served by the network entity.
