Abstract: Methods, systems, and devices for wireless communications that support power control in full duplex communication are described. In some wireless communications systems, a user equipment (UE) may experience antenna isolation for communication of downlink and uplink data traffic. Based on the antenna isolation, the UE may realize an increased channel capacity for full-duplex communication. As part of the full-duplex communication, the UE may identify characteristics of a potential downlink signal on formatted slots of the channel. The UE may determine an uplink transmit power control configured to account for the characteristics. The determination may include a configured transmit power control for beamformed signaling at the UE, and may be based on signal reception quality for potential downlink transmissions. Based on the determination, the UE may either perform uplink transmission on a resource block allocation of the formatted slots or forgo uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive and measure a reference signal received from a node and may transmit, to the node, a channel feedback report using a resource, the channel feedback report including a first Doppler shift associated with measuring the reference signal. In some examples, the uplink resource may be one of a set of uplink resources indicated to the UE, and the uplink resource may be based on a mobility parameter associated with the UE. Additionally or alternatively, the UE may measure a second reference signal received from the node and may transmit, to the node, a second channel feedback report using a second resource, where the second resource is based on measuring the first reference signal and where the second channel feedback report includes a second Doppler shift associated with measuring the second reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to techniques for multiple transmission and reception point (TRP) transmission of channel state information reference signal (CSI-RS) resources. In one aspect, a user equipment (UE) can receive a CSI-RS resource including a first CSI-RS port on a first beam from a first cell of a network entity, the CSI-RS resource including a second CSI-RS port of the second cell on a second beam from a second cell of the network entity. In another aspect, a network entity can transmit, on a first beam from a first cell to a UE, a CSI-RS resource including a first CSI-RS port of the first cell, and transmit, on a second beam from a second cell to the UE, the CSI-RS resource including a second CSI-RS port of the second cell.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indicator of a feedback window that is offset relative to a beginning transmission time interval (TTI) of a set of consecutive TTIs. The consecutive TTIs may include a set of aggregated slots or may correspond to a multi-TTI grant. The feedback window may include multiple control channel occasions interspersed within a duration of the set of consecutive TTIs. The UE may receive a transport block within a first TTI of the set of consecutive TTIs and transmit, within a control channel, feedback to indicate whether the transport block was successfully received.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may use beamforming to transmit control and data transmissions to a set of user equipments (UEs). A base station may transmit downlink control information (DCI) to UEs that may indicate a set of resource allocations in which the base station may schedule a data transmission, and a respective transmission configuration indicator (TCI) state. The TCI state may indicate which transmission beam the base station may use to transmit a data transmission in a particular resource allocation. The UE may receive and decode the DCI and identify resource allocation information and an index that may indicate one or more TCI states being used for transmitting a broadcast or unicast transmission to the UE within a resource allocation. The UE may select one or more of the resource allocations to monitor for, and subsequently receive, the data transmission.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI). An exemplary method, performed by a user equipment (UE), generally includes receiving, from a network entity, a downlink control information (DCI) for an update for at least of a beam or path loss (PL) reference signal (RS) activation and applying the update across at least one of a group of component carriers (CCs) or bandwidth parts (BWPs) within the group of CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine whether to transmit a sidelink timing synchronization signal to a second UE based at least in part on a sidelink zone in which the first UE is located and a sidelink zone in which the second UE is located. The first UE may selectively transmit the sidelink timing synchronization signal to the second UE based at least in part on determining whether to transmit the sidelink timing synchronization signal to the second UE. Numerous other aspects are provided.
