    摘要: Methods, systems (100), and devices for wireless communications are described. In some systems (100), a base station (105) and a user equipment (UE) (115) may communicate over a shared radio frequency spectrum and may employ time-division multiplexing (TDM) techniques to multiplex sensing signals (315) with wireless communications in the shared radio frequency spectrum. In some examples, the base station (105) may configure the UE (115) with a first retuning gap during which the UE (115) may retune a radio frequency chain of the UE (115) when transitioning from a sensing signal (315) pulse to wireless communications and with a second retuning gap during which the UE may retune the radio frequency chain when transitioning from wireless communications to a sensing signal (315). In some other examples, the base station (105) may configure the UE (115) with a phase and amplitude continuity status of multiple adjacent sensing signal (315) pulses that may indicate whether the multiple adjacent sensing signal (315) pulses have

    摘要: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may In support multiple component carriers that may be used to transmit uplink transmissions. One carrier may be used at a time such that the may switch between the carriers based on an uplink transmission schedule. In some cases, switching may be limited by a consecutive uplink switching rule or UE capability. In some cases, the gap between two consecutive uplink carrier switching operations may be limited to a resource (e.g., slot, symbol), such that the UE may expect to perform at most one switching operation per resource. In some implementations, the gap between two consecutive uplink carrier switching operations may be limited to a duration (e. g., 14 symbols, 4 symbols), such that the UE may expect to perform at most one switching operation per a duration less than or equal to a threshold.

    摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.

    摘要: Aspects of the present disclosure relate to techniques for non-codebook based uplink (UL) transmission. In some cases, a user equipment (UE) may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

    摘要: Certain aspects of the present disclosure relate to communication systems, and more particularly, to a partial channel state information reference signal (CSI-RS) port indication. A method by a base station (BS) includes configuring a user equipment (UE) with a CSI-RS resource, of one or more CSI-RS resources associated with a CSI report. The CSI-RS includes a set of CSI-RS ports. The BS provides a first indication to the UE of a subset of groups of the CSI-RS ports to be used by the UE for channel measurements and/or a second indication to the UE of a subset of groups of the CSI-RS to be used by the UE for interference measurements. Based on the indication, the UE performs channel measurements and/or interference measurements using the indicated subset of CSI-RS ports.
