Abstract: A method of wireless communication by a receiving sidelink user equipment (UE) includes receiving a first original message from a first transmitting sidelink UE. The method also includes receiving, from a network coding device, a network coded (NC) packet that is coded across the first original message and a second original message from a second transmitting sidelink UE. The first original message corresponds to a first transport block. The second original message corresponds to a second transport block. The method further includes transmitting a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded. The method still further includes transmitting a second NACK in response to the second transport block being unsuccessfully decoded. The method still further includes transmitting a first acknowledgment (ACK) in response to the first transport block being successfully decoded.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to one or more UEs, an SL transmission in a first direction using a first precoder. The example method may further include retransmitting, to the one or more UEs based on a configured maximum number of directional retransmissions and without allocating additional processes and memory for the packet, the SL transmission in one or more directions different from the first direction using one or more precoders different from the first precoder based on a SL retransmission configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to another UE, a positioning request associated with a procedure for determining a position of the UE, wherein the positioning request comprises a first sidelink communication between a first sidelink location management component (S-LMC) of the UE and a second S-LMC of the other UE, wherein the first S-LMC and the second S-LMC comprise sub-functions associated with a vehicle-to-everything protocol layer; receive, from the other UE, a second sidelink communication associated with the procedure for determining the position of the UE; and determine the position of the UE based at least in part on the second sidelink communication. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a buffer status report for a first sidelink transmission to a device. The first UE may receive, from a second UE, sidelink control information scheduling the first UE for a time resource for a second sidelink transmission from the second UE, the sidelink control information including an indication of a serving cell identifier of the second UE. The first UE may detect a half-duplex scheduling conflict, or a possible half-duplex scheduling conflict, based on the serving cell identifier and transmit an indication of the conflict to a serving base station. The base station may then assign, or re-assign, resources for the first sidelink transmission to avoid the scheduling conflict.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a mobile repeater. The mobile repeater measures broadcast signals from one or more target cells as the mobile repeater moves through a network. The mobile repeater selects one of the target cells, based on the measuring and side information. The mobile repeater forwards signals between a user equipment (UE) and the selected target cell.

Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.
