Abstract: In an aspect, a wireless node (e.g., UE or BS) measures, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and measures, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part. In another aspect, a UE transmits, at a first hop of a frequency hopping scheme, a reference signal (RS) on a first sub-band of an effective RS bandwidth, and transmits, at a second hop of the frequency hopping scheme, the RS on a second sub-band of the effective RS bandwidth, the first and second sub-bands of the effective RS bandwidth overlapping in part.

Abstract: Wireless communications systems and methods related to multi-transmission-reception point (multi-TRP) precoding matrix indication (PMI) operations are provided. A user equipment (UE) receives a configuration indicating a precoder size parameter for a plurality of transmission-reception points (TRPs). The UE receives, from a first TRP of the plurality of TRPs, a first reference signal. The UE receives, from a second TRP of the plurality of TRPs, a second reference signal, the second TRP being different from first TRP. The UE transmits, to the first TRP or the second TRP, a channel state information (CSI) report including a first feedback component based on the first reference signal and a second feedback component based on the second reference signal, where a combined payload size of the first feedback component and the second feedback component is based on the precoder size parameter.

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: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, at least one of a first downlink control information (DCI) or a second DCI, each DCI indicating at least one of one or more sets of one or more frequency domain (FD) bases and linear combination coefficients and transmit a PUSCH with subband precoding determined based on the first DCI, the second DCI, or a combination of the first and second DCI, depending on whether the first DCI is received, the second DCI is received, or both the first and second DCI are received.

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.
