Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

Abstract: To more efficient sidelink communications, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating includes transmitting a sidelink discovery probing message comprising at least a first identifier of the first sidelink device. The example method further includes monitoring for a probing response from a second sidelink device. The example method further includes transmitting a sidelink discovery message if the first sidelink device receives the probing response from the second sidelink device. The example method further includes skipping transmitting the sidelink discovery message if the first sidelink device does not receive the probing response from the second sidelink device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may multiplex a scheduling request (SR) associated with a first priority and a first physical uplink control channel (PUCCH) format with a hybrid automatic repeat request acknowledgement (HARQ-ACK) associated with a second priority and a second PUCCH format to form a multiplexed SR and HARQ-ACK. The UE may transmit, to a base station, the multiplexed SR and HARQ-ACK using a sequence in a PUCCH format 1 resource, wherein the sequence is based at least in part on whether the SR is a positive value or a negative value. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type. The UE may select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on a first priority associated with the first service type and a second priority associated with the second service type. Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described related to a slot format for low latency sidelink communications. A group of user equipments (UEs) may receive an indication of a configuration of a sidelink resource pool. The sidelink resource pool may include one or more slots and one or more subchannels, and a slot of the sidelink resource pool may include a control region allocated for a sidelink control channel and a set of contiguous subslots each allocated for a sidelink data channel. A first UE may transmit sidelink control information (SCI) to a second UE in the control region of a slot to reserve one or more subslot of the same slot or any quantity of different slots for a sidelink message. The first UE may transmit the sidelink message to the second UE in the subslot.

Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a configuration of multiple resource patterns for one or more user equipments (UEs) to use for transmission of sidelink signals over a quantity of transmission time intervals (TTIs) (e.g., sub-slots) within a slot. For example, a UE may determine a resource pattern to use for transmitting sidelink signals based on an assignment from a network entity, an initial frequency offset, information included in control signaling, or any combination thereof. In some examples, the UE may transmit, via the sidelink channel, an indication of the resource pattern used by the UE, such that other UEs in the system may determine the resource pattern used by the UE. The UE may transmit a sidelink signal in accordance with the resource pattern, while other UEs may use other resource patterns for sidelink transmissions within the same slot.
