    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of at least one sounding reference signal (SRS) resource set including at least five SRS resources or at least two SRS resource sets collectively including the at least five SRS resources, each SRS resource, of the at least five SRS resources, corresponding to an SRS port of at least five SRS ports. The UE may receive information indicating a set of selected SRS resources, including the at least five SRS resources, for an uplink transmission. The UE may transmit the uplink transmission based at least in part on the set of selected SRS resources. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify an uplink resource for reporting a Doppler measurement to a base station. The UE may determine a reference signal set precedes a reference point associated with the uplink resource prior to performing Doppler measurements based on the reference signals in the reference signal set. Each reference signal in the reference signal set may occur no later than a channel state information (CSI) reference resource, or an offset relative to the uplink resource defined by a number of symbols. The UE may determine the Doppler measurement based on the reference signal set, or multiple reference signal sets and may transmit the Doppler measurement to the base station in the uplink resource.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit data to a network device using an unencoded signal that includes parameters for updating a local data model. The UE may receive a radio network temporary identifier (RNTI) to decode a resource allocation message that schedules uplink resources for the transmission of the parameters, where the RNTI may be a dedicated RNTI that is different from other RNTIs received by the UE. The UE may identify allocated resources as scheduled by the resource allocation message, and may apply analog modulation and pre-equalization parameters to a data block to form an unencoded uplink transmission that includes the model parameters. The UE may transmit the unencoded uplink message in accordance with an over-the-air computation procedure.

    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be a user equipment (UE), may receive a message including an indication of a set of demodulation reference signal (DMRS) candidates for a data channel. The data channel may be a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) in some examples. The UE may determine a set of parameters associated with the set of DMRS candidates based on the received message. The set of parameters may correspond to a radio frequency spectrum subband or a radio frequency spectrum band associated with the data channel. The UE may estimate one or more characteristics of the data channel using the set of parameters associated with the set of DMRS candidates to perform wireless communication (e.g., PDSCH reception, PUSCH transmission).
