This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

A system described herein may provide a technique for location-based handling of discovery requests in a service-based network in which different instances of network functions (“NFs”) may be deployed in geographically diverse locations. For example, a Network Repository Function (“NRF”) may maintain location information for the various NF instances and may respond to discovery requests by identifying particular NF instances based on locations associated with the discovery requests. For example, such discovery requests may include a “preferred-locality” parameter or some other indication of location associated with the discovery request, based on which the NRF may identify one or more NF instances to provide in response to the discovery request.

Methods, systems, and devices for wireless communications are described that enable a user equipment (UE) in a distributed system to transmit measurement reports for layer 1 (L1) or layer 2 (L2) mobility on a per distributed unit (DU) basis such that each measurement report for L1/L2 mobility contains only measurements of cells that are supported by the same DU. The UE may generate and transmit a DU-specific measurement report to the DU (e.g., via L1/L2 signaling) that includes measurements of cells controlled by the DU. The UE may support various reporting configurations for measurement reporting including per cell, per group of activated cells, or per group of deactivated cells, in each case reporting to the corresponding DU. The UE may also perform joint reporting that includes the measurements of both activated and deactivated cell sets transmitted to the corresponding

The MIMO system may comprise at least one MIMO transmitter and at least one MIMO receiver. Feedback from one or more receivers may be used by a transmitter to improve quality, capacity, and scheduling in MIMO communication systems.

Specifically, a method for performing uplink transmission by a user equipment (UE) in a wireless communication system may comprise the steps of: receiving downlink control information (DCI) including sounding reference signal (SRS) resource indication (SRI) and precoding indication from a base station; and transmitting an uplink to the base station by applying precoding indicated by the precoding indication on an antenna port of an SRS transmitted within an SRS resource selected by the SRI.

A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).
