Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include monitoring a resource group of a sidelink channel for an indication of sidelink messaging traffic, determining a ratio of sidelink messaging traffic by a first radio access technology relative to sidelink messaging traffic by a second radio access technology based on the monitoring, selecting, based on the ratio, a first resource pattern of a set of multiple different resource patterns, and communicating, via the sidelink channel, a first sidelink message within a first resource of the resource group in accordance with the first resource pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an encoder device may transmit a network coded sidelink retransmission that is associated with a set of transport blocks (TBs), the set of TBs associated with one or more sidelink transmissions. The encoder device may receive, from one or more user equipments (UEs), first feedback information, associated with the network coded sidelink retransmission, that indicates whether the one or more UEs successfully decoded the set of TBs. The encoder device may transmit, to a base station, second feedback information associated with the network coded sidelink retransmission that is based at least in part on the first feedback information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit a first sidelink control information (SCI) message associated with a first sidelink transmission from the first UE, the first SCI including a first indication of a first set of resources reserved for retransmissions of the first sidelink transmission at one or more retransmission occasions. The UE may identify a second SCI message associated with the first SCI message, where the second SCI provides a release of at least a first subset of the first set of resources reserved for the retransmissions of the first sidelink transmission. The UE may then perform retransmissions of the first sidelink transmission in accordance with the release.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, from a transmitting device that is configured to perform network coding on information from an originating device, one or more transport blocks (TBs) including the information and associated with an erasure coding scheme. The receiving device may perform decoding using the erasure coding scheme and at least one TB, of the one or more TBs. The at least one TB is selected using one or more time conditions, one or more group conditions, one or more settings indicated by the transmitting device, or a combination thereof. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE. The UE may transmit, based at least in part on the UE being within an area associated with the network node, the request for the network node to perform the network coding for the communication. Numerous other aspects are described.

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, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a co-channel configuration. The co-channel configuration may indicate a set of sidelink parameters for a co-channel operation associated with dynamically utilizing sidelink radio frequency resources allocated for a first radio access technology and sidelink radio frequency resources allocated for a second radio access technology. The UE may transmit, based on the received co-channel configuration, an indication of a set of channel availability parameter values indicating an amount of available sidelink radio frequency resources associated with the first radio access technology, the second radio access technology, or both. Subsequently, the UE may receive a grant scheduling a set of sidelink resources for the wireless communication associated with the second radio access technology based on the transmitted indication of the set of channel availability parameter values for the co-channel operation.
