Abstract: Methods, systems, and devices for wireless communications are described to support resource selection for a sidelink transmission based on a priority of available resources. A physical (PHY) layer of a user equipment (UE) may report different subsets of available resources to a medium access control (MAC) layer. Each subset may be associated with a different priority and the MAC layer may use the subsets to select a resource for the sidelink transmission. The MAC layer may additionally or alternatively maintain a list of UE identifiers (IDs) and may provide the list of the UE IDs to the PHY layer for resource identification. The PHY layer may use the list to implement different reference signal parameters for UEs associated with the list of UE IDs than for other UEs. The PHY layer may report the set of available resources to the MAC layer, based on the list of UE IDs.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support controlling transmit power of one or more groups of user equipment (UE) sidelinks using a single sidelink control transmission of group transmit power control (TPC) information. A first UE may transmit group TPC information to one or more groups of UEs, such as by including the group TPC information in sidelink control information (SCI). The group TPC information may include a group TPC indicator and one or more TPC messages for providing one or more group TPC commands with respect to groups of sidelinks. The group TPC commands may provide for power control with respect to a respective group of UEs for one or more channels. Other aspects and features are also claimed and described.

Abstract: Aspects presented herein may enable a sidelink device to report or to receive HARQ feedback for sidelink channels based on a long PSFCH format. In one aspect, an apparatus transmits, to a second UE, an indication to provide HARQ feedback for at least one sidelink channel. The apparatus transmits, to the second UE, the at least one sidelink channel. The apparatus receives, from the second UE, an ACK or a NACK for the at least one sidelink channel via a PSFCH, the PSFCH including a long PSFCH format and associated with a sidelink resource pool.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide a user equipment (UE) with a capability to identify an enhanced sidelink resource pool including resources that are otherwise excluded from configured sidelink resource pools. In some examples, the UE may identify the enhanced sidelink resource pool based on sidelink parameters for transmitting one or more sidelink messages, and the UE may use the enhanced sidelink resource pool for additional sidelink transmissions. The additional sidelink transmissions may include standalone sidelink control information (SCI) transmissions or other types of transmissions associated with sidelink communications. The resources associated with the enhanced sidelink resource pool may have a relatively finer granularity than those included within a base sidelink resource pool that is, for example, configured by a network.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform single frequency network (SFN) manner relaying in sidelink to support exchanging packets between UEs, for example, without maintaining beamforming alignment between the UEs. A first UE (e.g., a source UE or destination UE) may establish a pre-agreement with a second UE for the second UE to operate as an SFN-manner relay over sidelink for the first UE. The pre-agreement may be reached via a publish-and-subscription procedure, in which the second UE publishes an SFN-type relaying service and the first UE subscribes to the SFN-type relaying service. The second UE may receive sidelink signaling associated with the first UE (e.g., transmitted by or to the first UE) and may relay the sidelink signaling in a resource configured for SFN-type transmission based on the first UE being subscribed to the SFN-type relaying service.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may receive a control message from a second UE indicating resources that are reserved for communications between the first UE and the second UE. The first UE may transmit a first control message and a second control message for reassurance of the reserved resources. The first UE may transmit a first control message for reservation reassurance, and the first control message may indicate a resource configuration for a second control message for reservation reassurance. The first UE may transmit an indication of the reserved resources, resource reservation reassurance information, or both via the second control message. A third UE may receive the first and second control messages and may refrain from communicating on the reserved resources based on the indication.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may determine a set of resources for sidelink communication with one or more neighboring UEs. The transmitting UE may transmit multiple sidelink control messages to the neighboring UEs indicating the set of resources are reserved for a sidelink data message. The neighboring UEs may receive at least one of the sidelink control messages. A neighboring UE may determine a portion of the resources are reserved for a sidelink data message with the transmitting UE and may transmit or receive the sidelink data message using the portion of the resources. Additionally or alternatively, a neighboring UE may determine the resources are reserved for a sidelink data message between the transmitting UE and another neighboring UE and may select alternative resources for sidelink data messages to may avoid using the reserved resources.

Abstract: Methods, systems, and devices for wireless communications are described that support evolved semi-persistent scheduling (SPS) for wireless communications. A base station may configure SPS in which multiple time intervals are scheduled, each time interval including multiple slots that may be scheduled by different uplink or downlink resource allocations. The SPS configuration may include an ON-OFF duty cycle where an ON portion of the duty cycle spans a portion of a time interval and includes uplink and downlink resources, and an OFF portion of the duty cycle spans a remaining portion of the time interval and does not include any allocated SPS resources. Such SPS configurations may be used, for example, for transmitting sensor data and command information between controllers and sensors/actuators in a factory automation network.

Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.
