Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a first set of resources for a physical sidelink shared channel (PSSCH) transmission. The UE may configure a second set of resources for a sidelink channel state information (CSI) reference signal (CSI-RS) transmission, the sidelink CSI-RS transmission is associated with the PSSCH transmission, and the sidelink CSI-RS transmission occurs prior to the PSSCH transmission. The UE may transmit a first sidelink control information (SCI) in a physical sidelink control channel (PSCCH) transmission, the first SCI including an indication of the first set of resources and the second set of resources. Numerous other aspects are provided.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes selecting, from a resource pool allocated for sidelink data transmission from a second wireless device to the first wireless device, a subset of the resource pool for the sidelink data transmission. The method generally includes transmitting an indication to the second wireless device of the selected subset of the resource pool. The method generally includes monitoring the subset of the resource pool for the sidelink data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A transmitter node and a relay node transmit, to a base station, feedback related to complex channel estimates associated with beam pairs providing viable paths for a first link between the transmitter node and the base station, a second link between the relay node and the base station, and a third link between the transmitter node and the relay node. The transmitter node transmits a signal to the base station using a transmit beam associated with a first beam pair and to the relay node using a transmit beam associated with a second beam pair. The base station receives the signal from the transmitter node and an estimate of the signal from the relay node via a receive beam configured based at least in part on the complex channel estimates included in the feedback. Numerous other aspects are provided.

Abstract: Aspects provide a mechanism for activating a secondary serving cell (SCell) in a wireless communication network supporting a multi-cell transmission environment. In some examples, a scheduled entity (e.g., a UE) in a connected mode with a primary serving cell (PCell) may synchronize with the SCell to activate the SCell for multi-cell communication with the PCell and the SCell. To enable synchronization with the SCell, the PCell may trigger communication and processing of one or more reference signals between the scheduled entity and the SCell.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a user equipment (UE) device within a wireless communication system determines one or more performance metrics associated with an operation of the UE. The UE selects, based at least in part on the one or more performance metrics, one or more sets of antenna elements from a plurality of sets of antenna elements available for an inter-band carrier aggregation communication across at least two radio frequency (RF) chains between the UE and one or more base stations. The UE sends an indication of the one or more selected sets of antenna elements from the UE to the one or more base stations.

Abstract: A first user equipment (UE) is configured to communicate with a second UE in sidelink communications using a sidelink configured grant (CG) configured by a base station. The first UE receives, a radio resource control (RRC) message or physical layer signaling including a sidelink configured grant (CG) configuration indicating at least some parameters configured by a base station for sidelink communications between the first UE and a second UE. The first UE transmits or receives a transport block for the sidelink communications on a physical sidelink shared channel (PSSCH) based on the at least some parameters.

Abstract: A UE may be configured to communicate using one of analog beamforming or hybrid beamforming. The UE may receive a set of beamformed signals from a base station. The UE may determine a set of angular spread values associated with a set of clusters in a channel between the base station and the UE based on the set of beamformed signals received from the base station. The UE may transmit the set of angular spread values to the base station. The UE may receive, from the base station based on the set of angular spread values, a set of transmission ranks associated with at least one cluster of the set of clusters. The UE may communicate at least one data stream with the base station across the at least one cluster using the set of transmission ranks associated with the at least one cluster of the set of clusters.

Abstract: In an embodiment, a UE establishes, with a peer sidelink UE, at least one sidelink communications link that each comprises one or more hops. The UE determines estimates a propagation delay between the UE and the peer sidelink UE based in part upon a relationship between a propagation time, between the UE and the peer sidelink UE, and Reference Signal Received Power (RSRP) irrespective of whether the UE remains synchronized with respect to the network clock.
