    Abstract: Methods, systems, and devices for wireless communications are described to support communication between a base station and a user equipment (UE) via multiple transmission reception points (TRPs). The base station may configure the UE to report a precoding matrix indicator (PMI) for various transmission modes, including one or more transmission modes for multiple TRPs. The UE may determine and report first PMI to the base station for each single TRP transmission mode, and the base station may use the first PMI to determine a precoding matrix for each TRP. The UE may determine and report partial PMI to the base station for the one or more multi-TRP transmission modes. The base station may use respective partial PMI to determine a precoding matrix for each multi-TRP transmission mode and may communicate with the UE using the determined precoding matrix or matrices.

    Abstract: 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.

    Abstract: 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.

    Abstract: The frequency domain basis may be fed back in a CSI report from a user equipment (UE), with extra overhead and computation cost. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive, from a base station, CSI reference signals (CSI-RS). The apparatus may be further configured to receive, from the base station, a configuration including a frequency domain basis restriction indicating a frequency domain basis subset, where the frequency domain basis subset is selected from a frequency domain basis set. The apparatus may be configured to prepare, upon receiving the frequency domain basis restriction, a CSI report based on the CSI-RS and the frequency domain basis subset. The apparatus may be further configured to transmit the CSI report to the base station.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure an uplink transmission pattern related to an uplink transmission resource on multiple component carriers. The base station may transmit, to a user equipment (UE), information related to activating the uplink transmission pattern in a single scheduling message. Accordingly, the UE may transmit information on the multiple component carriers in one or more uplink symbols based at least in part on the uplink transmission pattern. Numerous other aspects are provided.
