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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.

Abstract: A first user equipment (UE) may receive sidelink reservation information from one or more UEs. The first UE may transmit second stage sidelink control information (SCI), the second stage SCI comprising inter-UE coordination information based on the received sidelink reservation information from the one or more UEs and additional resource reservation information for the first UE, a format of the second stage SCI being indicated in a first stage SCI.

Abstract: The apparatus may be a first device at a first UE. The first device may be the first UE itself. The first UE may be configured to receive, from a second UE, a first reservation of an SL resource for a first SL transmission. The first UE may further be configured to receive, from a third UE, a second reservation of the SL resource for a second SL transmission within a threshold amount of time following the receipt of the first reservation. The first UE may also be configured to transmit a collision indication based on a collision parameter, the collision parameter being based on reception of the first reservation and the second reservation within the threshold amount of time.

Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.
