Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive signaling indicating one or more resource reservation rules associated with transmitting a sidelink message that includes reservation information associated with one or more sidelink resources. The first UE may determine, based on the one or more resource reservation rules, to include the sidelink message in a physical layer control signal, or a medium access control layer control signal, or both. The first UE may then transmit, to a second UE, the sidelink message in the physical layer control signal, or the medium access control layer control signal, or both based on the determining.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a sidelink user equipment (UE) may be configured with one or more prioritization rules for sidelink resource reservation forwarding. The UE monitor for one or more sidelink messages that indicate a set of sidelink resource reservations associated with one or more other UEs. In some examples, the UE may receive a sidelink message and one or more other sidelink messages that indicate reservations of other sidelink resources associated with other UEs. The UE may select one or more sets of sidelink resources for indicating in a coordination message in accordance with the one or more prioritization rules for sidelink resource reservation and based on the sidelink messages. The UE may transmit the coordination message including an indication of the one or more sets of sidelink resources based on the selecting.

Abstract: To provide more power efficient SPS transmission for sidelink UEs, methods, apparatuses, and computer-readable medium are provided. An example method may include selecting a first sidelink transmission resource for SPS based on a sidelink sensing procedure for UE-to-UE communication, the first sidelink transmission resource being associated with one or more subchannels within one or more slots. The example method may further include initiating a timer based on a timer range, the timer range being based on one or more of a battery level or a mobility associated with the UE. The example method may further include reselecting a second sidelink transmission resource or maintain the first sidelink transmission resource for the UE-to-UE communication upon an expiration of the timer.

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: In a particular implementation, a method of wireless communication includes transmitting, from a first user equipment (UE) to a second UE, a radio resource control (RRC) request that includes a first discontinuous reception (DRX) preference at the first UE. The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

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: A transmitting sidelink device assigns a transport block (TB) to a logical hybrid automatic repeat request (HARQ) entity, maps the TB to an carrier, transmits the TB to a receiving sidelink device, the TB is associated with a first sidelink control information (SCI) that cross-references the TB to an identifier of the logical HARQ entity, maps the TB to a different carrier, and retransmits the TB on the different carrier, the retransmitted TB is associated with a second SCI that cross-references the TB to the identifier of the logical HARQ entity. A receiving sidelink device receives the TB and SCI, maps the TB to the identified logical HARQ entity, detects the retransmission, and maps the retransmission to the identified logical HARQ entity. A transmitting sidelink device generates packets in advance and transmits one of the generated packets when required.

Abstract: In an aspect, the disclosure provides a method of wireless communication for a first user equipment (UE). The method may include decoding, at a first user equipment (UE), sidelink control information (SCI) transmitted by a plurality of second UEs reserving a set of resources for sidelink transmission to the first UE. The method may also include detecting, at the first UE, a potential resource collision between the plurality of second UEs at the set of resources based on decoding of the SCI. The method may further include generating a pre-collision message that identifies the set of resources that are susceptible to the resource collision. The method may further include transmitting the pre-collision message from the first UE to the plurality of second UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive an indication of one or more parameters for communications over a sidelink channel during a first time period, where the one or more parameters may include a time threshold for a second resource pool. The wireless device may transmit data over a first resource pool of the sidelink channel during a first portion of the first time period based on the one or more parameters, the first resource pool including resources for communications between the first wireless device and a second wireless device. The wireless device may monitor the second resource pool during a second portion of the first time period for the time threshold, the second resource pool including resources for communications between the first wireless device and a third wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may select a vehicle-to-anything (V2X) resource from a resource pool partitioned between New Radio (NR) V2X resources and Long Term Evolution (LTE) V2X resources if an NR V2X traffic parameter does not satisfy a traffic threshold, or from a non-partitioned resource pool if the NR V2X traffic parameter satisfies the traffic threshold. The mobile station may transmit a V2X communication in the V2X resource. Numerous other aspects are described.
