Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive a resource reservation for one or more resources in a resource pool configured for sidelink communication. The mobile station may transmit an indication of the resource reservation using an entry-based format or a bitmap-based format, wherein the entry-based format or the bitmap-based format is selected based at least in part on a configuration of the resource pool, a periodicity of the resource reservation, or whether the resource reservation is multiplexed with sidelink data. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information identifying the UE as a relay node and indicating for the UE to schedule resources for other UEs. The UE may receive a single message from a network entity with the configuration information or multiple messages from the network entity with the configuration information. A remote UE may request scheduling information from the relay UE. A network entity, such as a base station, may provide one or more resources (e.g., time resources, frequency resources, or both) for the relay UE to schedule one or more remote UEs. The relay UE may send scheduling information to the one or more remote UEs based on receiving the resources.

Abstract: An encoding device transmits an indication for a plurality of user equipments (UEs) to provide feedback for a network coding packet across multiple time periods. The encoding device transmits the network coding packet; and receives the feedback from the plurality of UEs across the multiple time periods. A UE receives an indication to provide feedback for a network coding packet that is staggered in a different time period than a baseline time period. The UE receives the network coding packet and transmits the feedback in one time period among multiple time periods associated with the network coding packet.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for retransmission of sidelink transmissions using network coding. A transmitting device transmits a transport block and a request for a NC encoding device to retransmit the transport block to a plurality of UEs. The NC encoding device transmits a packet encoding a plurality of transport blocks previously transmitted by one or more transmitting devices. The NC encoding device receives a plurality of acknowledgments (ACK) or negative acknowledgments (NACK) for the plurality of transport blocks from the plurality of UEs. The NC encoding device determines whether a respective transport block has satisfied an ACK condition based on the plurality of ACKs or NACKs from the plurality of UEs. The NC encoding device transmits an acknowledgment message to the one or more transmitting devices for at least the respective transport block.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first sidelink pathloss based at least in part on a first sidelink reference signal from a second UE. The first UE may also determine a second sidelink pathloss based at least in part on a second sidelink reference signal received from a third UE. The first UE may transmit, during a transmission time interval, a first sidelink transmission to the second UE using a first transmit power that is based at least in part on the first sidelink pathloss and a second sidelink transmission to the third UE using a second transmit power that is based at least in part on the second sidelink pathloss. The first sidelink transmission may be transmitted at a first frequency and the second sidelink transmission may be transmitted at a second frequency.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may communicate with one or more other UEs in accordance with a distributed resource allocation mode. To select suitable resources for an intended sidelink transmission, the first UE may transmit, to a second UE, a request for a type of coordination information based on information associated with the intended sidelink transmission from the first UE. The second UE may generate coordination information in accordance with the requested type and may transmit the coordination information to the first UE. The first UE may use the coordination information to select a set of resources over which to perform the intended sidelink transmission from the first UE and may perform the intended sidelink transmission over the selected set of resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select, based at least in part on channel sensing, one or more subchannels for transmitting information for coordinating sidelink resources with one or more other UEs. The first UE may transmit, to at least a second UE, sidelink control information (SCI) that indicates the one or more subchannels and one or more data transmission occasions in which the information is to be transmitted. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a control message indicating reservation of a first resource of a sidelink channel for a sidelink transmission. The first UE may receive a pre-conflict indication for the first resource based on the control message. In some cases, the first UE may disregard the pre-conflict indication, or may not disregard the conflict indication based on one or more factors. The first UE may perform resource re-selection to select a second resource for the sidelink transmission if the first UE receives the conflict indication at least a threshold amount of time prior to the first resource, and may transmit using the second resource. Otherwise, the first UE may report a negative acknowledgement (NACK) message from a physical (PHY) layer to a medium access control (MAC) layer.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify a set of time and frequency resources to reserve for one of sidelink transmissions by a second UE to the first UE or to one or more third UEs (e.g., type A), or sidelink transmissions by the first UE to one or more third UEs (e.g., type B), and may select a first indicator and a second indicator for the reservation. The first indicator of a time resource and the second indicator of a frequency resource may be associated with the identified set of time and frequency resources for the reservation. The UE may transmit, to the second UE, a coordination message that includes the first indicator and the second indicator, and includes an indication that the message is associated with type A or type B reservations.
