Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for the establishment of a communication link between a base station and a user equipment (UE). The UE may have a spatial partial reciprocity capability. The UE may be configured to determine antenna cross-correlation information for at least a first subset of antenna elements in the UE. The cross-correlation information may include one or more correlation parameters (e.g., correlation coefficients), a correlation model, or both. The UE may transmit sounding reference signals for a second set of antenna elements in accordance with the spatial partial reciprocity capability. The UE may also transmit an indication of the cross-correlation information for at least the first subset of antenna elements of the UE. The base station may use such information to derive correlation parameters for the unsounded antennas and determine precoders for downlink communications.

Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: A method for wireless communication by a user equipment includes receiving, from a network node, a first message configuring a group of inactivity timers including indicating a respective timer duration value for each inactivity timer of the group of inactivity timers. Each inactivity timer of the group of inactivity timers may be associated with a respective network power saving mode of a group of network power saving modes. The method also includes initiating a first inactivity timer of the group of inactivity timers with a respective timer duration value based on receiving a first downlink transmission from the network node or transmitting first uplink information to the network node. The method further includes enabling a radio resource control (RRC) state of a group of RRC states based on an expiration of the first inactivity timer.

Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.

In some aspects, a user equipment (UE) may receive, from a network node, a measurement configuration indicating one or more punctured resources of a physical downlink shared channel (PDSCH) that can be used for measurements associated with estimating an interference plus noise covariance (INC) matrix at the UE. The UE may receive, from the network node, a reporting configuration indicating one or more INC matrices at the UE to be reported. The UE may transmit, to the network node, a report indicating the one or more INC matrices at the UE based at least in part on receiving the reporting configuration. Numerous other aspects are provided.

Abstract: Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.
