Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects involve enhancing an inter-user-equipment coordination (IUC) framework to enable user equipment (UE) to perform beam sweeping over the sidelink. Some aspects more specifically relate to fine-tuning beams, such as transmit beams or receive beams, using one or more IUC requests. In some aspects, multiple transmit beams or multiple receive beams may carry respective IUC requests and associated beam signals. In some aspects, one transmit beam or one receive beam may carry an IUC request and associated beam signal, multiple remaining transmit beams or receive beams may carry associated beam signals, and the transmit UE or the receive UE may identify a fine-tuned transmit beam or a fine-tuned receive beam responsive to, based on, or otherwise associated with the IUC request and associated beam signals.

Abstract: Methods, systems, and devices for wireless communication are described. A central unit (CU) of a network entity may receive, from a first user equipment (UE) via a second UE, a connection setup request message for a first UE. The CU may establish UE context information for the first UE at an adaptation layer of the CU, the CE context information based at least in part on communications between the first UE and the network entity via the second UE. The CU may transmit, to a distributed unit (DU) associated with the CU, an indication of a relaying configuration for the first UE connecting to the network entity via the second UE, the relaying configuration comprising multiplexing and forwarding information for a connection between the second UE the DU. The CU may communicate with the first UE via the second UE according to the UE context information and the relaying configuration.

Abstract: Methods, systems, and devices for remote user equipment (UE) discovery and link establishment for reduced capability UE are described. In some examples, a relay UE may transmit one or more discovery messages associated with establishing a sidelink relay communication link between the relay UE and a remote UE having a reduced communication bandwidth capability relative to the relay UE. In such examples, the relay UE may perform a communication bandwidth configuration procedure with the remote UE based on the remote UE having the reduced communication bandwidth capability relative to the relay UE. In some examples, the relay UE and the remote UE may establish, in accordance with the communication bandwidth configuration procedure, the sidelink relay communication link between the relay UE and the remote UE using a reduced communication bandwidth that is less than a full communication bandwidth allocated for the relay UE.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit, to a base station, a first uplink message including one or both of a protocol layer source identifier associated with a second UE or a request for a local identifier associated with the second UE. The first UE may receive, from the base station, a first downlink message including a downlink signal radio bearer (DL SRB) message, and the DL SRB message including one or both of the protocol layer source identifier associated with the second UE or the local identifier associated with the second UE in a downlink adaptation layer header of the DL SRB message. The first UE may transmit, to the second UE, in a sidelink adaptation layer header of a sidelink message, the local identifier associated with the second UE based in part on the received first downlink message.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. An example method includes receiving configuration information indicating one or more configurations for an initial sidelink beamforming procedure involving one or more transmit beams, each associated with a respective antenna panel of a first UE, and performing the initial sidelink beamforming procedure based on the configuration information. Performing the initial sidelink beamforming procedure includes transmitting at least a first beamforming burst, comprising transmitting each beamforming transmission of one or more beamforming transmissions using a different respective transmit beam of the one or more transmit beams of one or more antenna panels of a first UE, monitoring for at least one response message from a second UE responding to at least one of the one or more beamforming transmissions, and taking one or more actions based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A remote user equipment (UE) may establish a first connection with a relay UE that is in communication with a base station via a second connection. The first connection may be of a first connection type and the second connection may be of a second connection type. The remote UE may identify a mapping between one or more first quality of service (QOS) parameters corresponding to the first connection type and one or more second QoS parameters corresponding to the second connection type. The remote UE may determine, using the mapping, a first QoS parameter to be applied to the first connection as part of an end-to-end (E2E) connection with the base station via the relay UE, and communicate with the base station via the relay UE using the E2E connection.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.
