Abstract: Method and apparatus for null-forming at bidirectional smart repeaters. The apparatus transmits, to a repeater, a repeater configuration. The repeater configuration configures the repeater to beam shape at least one beam of the repeater to suppress at least one side lobe of the at least one beam. The apparatus communicates with the repeater based on the repeater configuration. The apparatus receives, from the repeater, information related to an existing codebook of the repeater and associated beam forming capabilities of the repeater. The apparatus receives, from the repeater, information related to a null-forming codebook configured at the repeater.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE (e.g., an initiator UE) transmits sidelink discovery messages for beam training on a bandwidth associated with DMRS. One or more UEs (e.g., candidate responder UEs) select a beam to pair with a beam associated with one of the sidelink discovery messages, and transmit a sidelink discovery message on the selected beam. In another aspect, a UE (e.g., initiator UE) transmits a sidelink discovery message, which is forwarded to a UE, which may be a lead UE of a sidelink UE group. The lead UE adds the initiator UE to the sidelink UE group, and responds with a sidelink discovery response message and a group indication that at least indicates that the initiator UE now belongs to the sidelink UE group.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for cross-carrier sidelink channel state information (CSI) reporting. One aspect provides a method for wireless communication by a first user equipment (UE). The method generally includes transmitting, to a second UE, one or more channel state information (CSI) requests on one or more first component carriers (CCs), via one or more sidelink control informations (SCIs) that includes a CSI request flag and receiving, in response to the one or more CSI requests, one or more CSI reports from the second UE on one or more second CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB)-donor central unit (CU) may trigger connectivity between a distributed unit (DU) of a first network node and the IAB-donor CU, wherein the first network node comprises an IAB-node. The IAB may instantiate connectivity between a mobile terminal (MT) of the first network node and the IAB-donor CU after instantiation of the connectivity between the DU of the first network node and the IAB-donor CU. The IAB may transmit a communication to a second network node via the first network node. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for providing a probabilistic feedback parameter. One example method for wireless communication may be performed by a first wireless node. The method generally includes generating a feedback message indicating a probabilistic estimate comprising a plurality of feedback parameter values and a plurality of value probabilities, wherein each value probability is associated with one feedback parameter value of the plurality of feedback parameter values, and transmitting the feedback message to a second wireless node.

Abstract: Aspects presented herein may provide various power saving techniques and features for network nodes by configuring different power saving modes for the network nodes. Aspects presented herein may enable a network node to transmit SSBs less frequently to reduce an amount of power utilized. In one aspect, a base station configures a plurality of SSB Tx periodicities associated with a plurality of ES modes. The base station transmits an indication of the plurality of SSB Tx periodicities associated with the plurality of ES modes. The base station transmits one or more SSBs based on one of the plurality of SSB Tx periodicities associated with one of the plurality of ES modes.

Abstract: Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.

Abstract: A first UE may select, based on a resource pool configuration for a sidelink communication, at least one of a first slot in time or a second slot in time of a plurality of slots. The plurality of slots may be associated with DMRS bundling. The first UE may configure, based on the DMRS bundling, at least one of one or more symbols in the first slot in time from a gap symbol to a non-gap symbol or one or more symbols in the second slot in time from an AGC symbol to a non-AGC symbol. The first UE may transmit, to a second UE, an indication of the configuration of the at least one of the one or more symbols in the first slot in time or the one or more symbols in the second slot in time.

Abstract: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics
