    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 relaxed sensing for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method by a user equipment (UE) of wireless communication includes identifying a resource selection trigger that indicates selection of one or more sidelink slots from a resource selection window. The UE may obtain long-term interference sensing statistics observed by the UE prior to the resource selection trigger. The UE can reduce a default sensing window length in accordance with the long-term interference sensing statistics and transmit a sidelink transmission in the selected sidelink slots. Other aspects and features are also claimed and described.

    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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some aspects, a base station (BS) and a user equipment (UE) may communicate with one another over a sequence of unique frequency sub-bands of a frequency hopping pattern. In some instances, the BS and the UE may switch from a current frequency sub-band to another frequency sub-band based on a number of unsuccessful attempts to gain access to the current frequency sub-band. In some other instances, the BS and the UE may communicate data using configured grant (CG) resources based on a number of unsuccessful attempts to gain access to the current frequency sub-band.

    IPC: H04W72/04

    Abstract: Methods, systems, and devices for wireless communications are described in which a first user equipment (UE) may transmit sidelink communications to a second UE, and the second UE may provide feedback associated with the sidelink communication to the first UE in a sidelink control information (SCI) transmission. In some cases, the SCI is first stage SCI transmitted in a sidelink control channel or second stage SCI transmitted in a sidelink shared channel. The feedback may include one or more of acknowledgment/negative-acknowledgment feedback, channel state information feedback, a scheduling request, or any combinations thereof. In some cases, the first UE may indicate resources of the second slot to the second UE for transmission of the feedback in the SCI, such as by providing a time offset value and resource index that identifies the resources.

    Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive control signaling indicating multiple sidelink channels of a sidelink resource pool, a mapping between each sidelink channel of the multiple sidelink channels to a corresponding feedback channel of multiple feedback channels, and a time gap between sidelink channel transmission and feedback transmission with respect to a feedback channel sub-slot of multiple feedback channel sub-slots within a slot. Accordingly, the first wireless device may receive a sidelink data message on a first sidelink channel of the multiple sidelink channels and may transmit sidelink feedback information for the sidelink data message in the feedback channel sub-slot of the slot on a first feedback channel of the multiple feedback channels corresponding to the first sidelink channel. The described techniques may enable the first wireless device to transmit the sidelink feedback information with reduced latency and improved reliability.
