Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., Tx UE) may transmit or receive a first control message indicating a sidelink beam measurement configuration for performing a sidelink beam sweep procedure using a set of transmit beams. The first UE may select a subset of transmit beams from the set of transmit beams for the sidelink beam sweep procedure based on one or more parameters associated with the sidelink beam measurement configuration. The first UE may then transmit, to a second UE (e.g., Rx UE) during the sidelink beam sweep procedure, a set of sidelink reference signals using respective transmit beams of the subset of transmit beams.

Abstract: A target user equipment (UE) may receive, from each relay UE of a set of relay UEs, a synchronization signal block (SSB) through each transmit beam of a set of transmit beams from the UE through each receive beam of a set of receive beams at the target UE. The relay UE may transmit the paging message through each transmit beam of the set of transmit beams. The target UE may determine a beam pair based on the received SSB, and receive the paging messaged using the beam pair. The target UE may also receive, from a relay UE, a paging message through one or more sidelink channels from each transmit beam of a set of transmit beams of the relay UE through each receive beam of a set of receive beams at the target UE and decode the received paging message.

Abstract: A method of wireless communication for a user equipment (UE) includes entering a dormancy period for a secondary cell group (SCG) of a base station (BS) during which no downlink (DL) data or control transmissions are received from the SCG; performing a channel state information (CSI) measurement on the SCG during the dormancy period to generate a measurement report; determining an uplink (UL) beam of a primary secondary cell (PSCELL) of the SCG; transmitting the measurement report to the BS on the UL beam of the SCG; and determining, during the dormancy period and after transmitting the measurement report, one or more downlink (DL) beams for communicating on the SCG based on one or more rules and based on the measurement report, wherein the one or more rules result in the BS determining the same one or more DL beams based on the measurement report.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an originator UE transmits a sidelink beam training (BT) reference signal (BTRS) a first number of times on each of a first set of beams, and a sidelink discovery message a second number of times on each of a second set of beams, wherein each beam from the second set of beams is associated with at least one beam from the first set of beams (e.g., 1:1 or N:1 mapping of first set of beams to second set of beams). At least one responder UE responds by transmitting, after the transmission of the sidelink BTRSs and the sidelink discovery messages, a BT response signal and a sidelink discovery response message on a beam corresponding to one of the first set of beams.

Abstract: In embodiments of systems and methods for managing communication between a wireless device and a base station, a base station may transmit Remaining Minimum System Information (RMSI) Downlink Control Information (DCI) indicating time and frequency resources for RMSI. A wireless device may receive a Channel State Indicator-Reference Signal (CSI-RS) based on the time and frequency resources for RMSI and may select a sub-beam of a beam associated with a synchronization signal block (SSB). The wireless device may send to the base station an indication of the selected sub-beam associated with the SSB in a Physical Random Access Channel (PRACH) message. The base station and the wireless device each may then perform an initial access procedure using the selected sub-beam to enable the wireless device to establish a communication link with the base station.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically scheduling antenna resources of a wireless node, such as, antenna panels of a user equipment (UE). In some cases, a first node (e.g., a UE) performs, with two or more other nodes, a first beam sweep procedure across two or more antenna resources of the first node on two or more wireless interfaces, generates or obtains scheduling information based on results of the first beam sweep procedure, wherein the scheduling information indicates which of the antenna resources is scheduled for which wireless interfaces, and communicates with the other nodes on the wireless interfaces according to the scheduling information.

Abstract: The apparatus of wireless communication may be a UE configured to activate a MAC-CE transmitted over an SL relay after waiting a time period by receiving an activation request for a command in association with a third UE in a first MAC-CE relayed from a second UE, transmitting, to the second UE, a second MAC-CE including an activation response to the third UE in response to the activation request, and activating the command after transmitting the activation response. The UE may wait a time period after transmitting the activation response before activating the command. The UE may receive an HARQ ACK from the third UE in response to the transmitted activation response or an HARQ ACK from the second UE in response to the transmitted activation response, and wait a time period after receiving the HARQ ACK before activating the command.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a configuration for reporting beam failure detection (BFD) reports via a relay device. The UE may also receive a control message activating BFD reporting at the UE in accordance with the configuration. The UE may monitor for reference signals from a network entity, and may determine one or more beam failure instance (BFI) indicators that pertain to communications between the UE and the network entity. The UE may transmit a BFD report via the relay device in accordance with the configuration. The UE may transmit the BFD report prior to a beam failure declaration that occurs when a quantity of the one or more BFI indicators exceeds a threshold. The techniques described herein may reduce the likelihood of beam failures occurring between the UE and the network entity.
