Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) that indicates that the UE is configured with a quantity of receive elements that is greater relative to a quantity of transmit elements with which the UE is configured. The UE may receive, based at least in part on transmitting the SRS, a first channel state information (CSI) reference signal (CSI-RS) set and a second CSI-RS set. The UE may transmit a CSI report that is based at least in part on the first CSI-RS set and the second CSI-RS set. Numerous other aspects are provided.

Abstract: A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.

Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration for a multiple transmission reception point (TRP) transmission, such as a non-coherent joint transmission (NCJT). A method by a base station (BS) includes providing a user equipment (UE) with a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource comprising a set of ports or port groups. The BS signals the UE to enable the UE to send a CSI report including CSI for more than one CSI-RS resource or for a CSI-RS resource comprising more than one port group and receives a CSI report from the UE.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include an energy harvesting (EH) device receiving a first control signal that includes scheduling information for the EH device. The scheduling information may indicate a first set of resources for communicating a first signal and a first offset between receiving the first control signal and communicating the first signal. Further, the method may include transmitting, via a second set of resources, a second signal indicating a second offset between receiving the first control signal and communicating the first signal and communicating the first signal via the first set of resources based on the second offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink component carrier based at least in part on the communication received from the second UE, wherein the sidelink component carrier is associated with conveying the sidelink HARQ-ACK feedback when sidelink carrier aggregation is configured for a group of UEs that includes the first UE and the second UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing uplink control information (UCI) on physical uplink control channel (PUCCH) resources for non-ideal backhaul based multi-transmission/reception point non-coherent joint transmissions. An example method generally includes determining that a first set of physical uplink control channel (PUCCH) resources configured for reporting channel state information (CSI) overlaps with a second set of PUCCH resources indicated for reporting hybrid automatic repeat request (HARQ) feedback, wherein the first and second sets of PUCCH resources are associated with downlink demodulation reference signal (DMRS) port groups, generating CSI reports and HARQ feedback associated with at least one of the downlink DMRS port groups, and transmitting the CSI reports and the HARQ feedback, multiplexed using the second set of PUCCH resources.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate one or more wake-up radio (WUR) configurations to a user equipment (UE), which may communicate a desired WUR configuration with the network entity. The UE may indicate a request for the desired WUR configuration, may multiplex the request with another signal associated with the UE, or both. Additionally, or alternatively, the network entity may indicate a single WUR configuration to the UE, which may be determined according to desired configurations, a class of WUR, or both associated with a group of UEs including the UE. Such techniques may support a reduced overall power expenditure of the UE by improving WUR operation.

Abstract: Methods, systems, and devices for wireless communications are described. A relay node may establish a control plane connection between the relay node and a base station, wherein establishing the control plane connection comprises receiving from the base station a first network identifier for the relay node. The relay node may receive, via the control plane connection, a relay configuration from the base station. The relay node may monitor grants associated with a set of one or more user equipment (UEs) based at least in part on the relay configuration, each UE comprising a network identifier that is different from the first network identifier. The relay node may relay communications between the base station and the set of one or more UEs according to the monitoring.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to rate matching for new radio (NR) physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH). In certain aspects, a method includes receiving a rate matching resource (RMR) configuration from a serving cell. The method also includes identifying one or more first resource elements (REs) to be rate matched around at least in part based on a transmission numerology associated with the RMR configuration, wherein the one or more first REs are used for reference signal (RS) transmission in the serving cell or a neighboring cell. The method further includes mapping a physical downlink shared channel (PDSCH) to one or more second REs not including the first REs.
