Abstract: A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.

Abstract: Wireless communication devices are adapted to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a reservation signal to reserve one or more sidelink resources for use by another device, and receive a sidelink transmission from the other device on at least a portion of the one or more reserved sidelink resources. According to another example, a wireless communication device can detect a reservation signal from another device, where the reservation signal is configured to reserve one or more sidelink resources, and transmit a sidelink transmission on at least a portion of the one or more of the sidelink resources reserved by the other device. Other aspects, embodiments, and features are also included.

Abstract: Aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a peer-to-peer (P2P) communication is to be relayed based at least in part on a location of the UE and a range requirement associated with the P2P communication; and transmit the P2P communication, wherein the P2P communication includes an indication of whether the P2P communication is to be relayed. In some aspects, a UE may receive the P2P communication; determine whether to relay the P2P communication based at least in part on the indication and at least one of: a location of the UE, or a UE identifier, included in the P2P communication, that identifies the UE and is associated with a request for the UE to relay the P2P communication; and selectively relay the P2P communication based at least in part on determining whether to relay the P2P communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) to be scheduled by a scheduler UE in a sidelink system may transmit a first scheduling request (SR) to request sidelink resources. The UE may transmit the first SR via a set of feedback resources. The scheduler UE may transmit, to the UE, a sidelink control message to schedule a sidelink transmission. The sidelink control message may indicate a set of feedback resources mapped to the sidelink transmission. The UE may transmit the scheduled sidelink transmission based on the sidelink control message and may request additional sidelink resources. The UE may transmit a second SR, where the second SR is transmitted via the set of feedback resources mapped to the sidelink transmission.

Abstract: Wireless communications systems and methods related to sidelink communications in a TDD system are provided. A first user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) configuration. The first UE may select a first TDD configuration from a set of configured TDD configurations based on the TDD configuration. Additionally, the first UE may transmit to a second UE, an indication of the first TDD configuration. The first and the second UEs may communicate a sidelink communication based on the first TDD configuration. Other features are also claimed and described.

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: Methods, systems, and devices for wireless communications are described. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive scheduling information that schedules an uplink data message over a high priority physical uplink shared channel (PUSCH) that overlaps in time with a physical uplink control channel (PUCCH) resource over which the UE is scheduled to transmit feedback associated with sidelink communication. The UE may receive signaling from a base station indicating whether the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH. As such, the UE may multiplex the feedback associated with the sidelink communication on the high priority PUSCH if the signaling from the base station indicates that the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether sufficient resources are available to perform a transmission in a current slot. The UE may transmit the transmission in the current slot, transmit an early reservation signal for a future resource, or determine whether sufficient resources are available to perform the transmission in a subsequent slot based at least in part on a probability-based determination and based at least in part on whether sufficient resources are available to perform the transmission in the current slot. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. Numerous other aspects are provided.
