Abstract: Certain aspects of the present disclosure provide techniques for sidelink feedback in resource pool. 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: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus configures at least a non-access stratum (NAS) protocol layer or a radio resource control (RRC) protocol layer to enable device-to-device (D2D) communication with at least a second apparatus when the apparatus is out of network coverage, and communicates with at least the second apparatus.

Abstract: The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting system information on sidelink. A method that may be performed by a first user equipment (UE) includes receiving first system information from a second UE; determining, based on one or more first parameters, to receive second system information from the second UE; receiving the second system information in a sidelink system information block (S-SIB) from the second UE; and communicating with the second UE via sidelink resources determined based on the first system information and the second system information.

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.
