Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may receive, from a second wireless node (e.g., a base station), a downlink signaling message indicating a synchronization signal block (SSB) grouping based at least in part on a full-duplex capability and transmission directions associated with the second wireless node. The first wireless node may configure, and the second wireless node may perform, a beam search and/or a self-interference measurement to identify at least one candidate downlink and uplink beam pair suitable for full-duplex operation based at least in part on the SSB grouping. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: A method of wireless communication wireless communication by an identifier-receiving user equipment (UE) includes measuring a received signal power of multiple resource UEs. The method also includes receiving a set of identifiers from an identifier-transmitting UE. The method further includes identifying a resource used by at least one of the multiple resource UEs for a future transmission from the identifier-receiving UE based on the measured received signal power and the received set of identifiers. The method still further includes scheduling the future transmission on the at least one identified resource.

Abstract: Certain aspects of the present disclosure provide a method for performing beam measurements in a wireless communication network, including: performing a measurement of a first beam from a first transmission and reception point (TRP) of a network; performing a measurement of a second beam from a plurality of TRPs of the network; applying a biasing factor to one of the measurement of the first beam or the measurement of the second beam based on a beam preference setting; and transmitting, to the network, a measurement report including: indications of the first beam and second beam to which the measurement report pertains; and the measurement of the first beam and the measurement of the second beam after applying the biasing factor.

Abstract: A method of wireless communication by a transmitting sidelink user equipment (UE) determines at least one quasi-co-location (QCL) relationship between antenna ports of the transmitting sidelink UE. The QCL relationship corresponds to carrier frequency offset (CFO), average delay, delay spread, Doppler shift, and/or Doppler spread across the antenna ports of the transmitting sidelink UE. Each port maps to a different transmission and reception point (TRP). The method also indicates the QCL relationship(s) to a receiving sidelink UE. A method of wireless communication by a receiving sidelink UE receives a message from TRPs of a transmitting sidelink UE. The message indicates a QCL assumption for the TRPs. The method also individually measures reference signals received from each transmission port of the TRPs. The method may also determine whether signaling from the TRPs satisfies all conditions for the QCL assumption, and report to the transmitting sidelink UE a result of the determining.

Abstract: The present disclosure relates to selections of a channel state information (CSI) report setting option by a distinct demodulation reference signal (DMRS) pattern. Specifically, in one aspect, a user equipment (UE) may determine a CSI transmission setting based on the at least one measurement of the communication channel, the CSI transmission setting is associated with a distinct DMRS pattern, and transmit a CSI report with the distinct DMRS pattern to the network entity in accordance with the CSI transmission setting. In another aspect, a network entity may transmit CSI setting configuration information to a UE, the CSI setting configuration information including at least one parameter corresponding to a channel measurement threshold that triggers selection of a distinct DMRS pattern based on a CSI transmission setting, and receive a CSI report and the distinct DMRS pattern from the UE associated with the CSI transmission setting.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications between a first UE and a second UE. The method includes, at the first UE, receiving, from the second UE, a paging indication message on a sidelink channel, the paging indication message associating the first UE with one or more resources of a common resource pool that includes a plurality of resources for communication on the sidelink channel. The method further includes, based on the received paging indication message, monitoring the one or more resources for a message from the second UE.

Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.

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.
