Abstract: Disclosed are techniques for determining locations of reference nodes. In an aspect, an apparatus transmits a request to a first reference node to perform a first round-trip-time (RTT) procedure with a second reference node, determines a first distance between the first reference node and the second reference node based on the RTT procedure, determines relative locations of the first and second reference nodes with respect to each other, and determines absolute locations of the first and second reference nodes from their relative locations based on at least one of the first and second reference nodes having a known absolute location and at least one known angle-of-arrival (AoA) or angle-of-departure (AoD) of at least one reference signal.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that identifies a set of uplink resources. The UE may determine whether a timing of the grant overlaps with a repetition window of a grant-free uplink communication configured on the UE. The UE may process the grant based at least in part on whether the timing of the grant overlaps with the repetition window of the grant-free uplink communication. Numerous other aspects are provided.

Abstract: A two stage scrambling design is provided for generating and decoding Resource Spread Multiple Access (RSMA) modulated streams. A User equipment (UE) scrambles each data stream of a set of data streams using a first scrambling sequence to generate a first set of scrambled data streams, and then scrambles the first set of scrambled data streams using a second scrambling sequence to generate a second set of scrambled data streams, wherein the second scrambling sequence is longer than the first scrambling sequence. The UE then transmits the second set of scrambled data streams. A receiving base station determines the first and second scrambling sequences used by the UE and decodes the transmissions received from the UE based on the determined scrambling sequences.

Abstract: Various aspects described herein relate to distinguishing frequency shift keying (FSK) signals transmitted by each user of multiple users in a wireless communications system. One or more symbols for transmitting in an FSK-modulated signal can be obtained by a user. The one or more symbols can be encoded based on a tone location assignment corresponding to a unique spreading code associated with the user. Quadrature amplitude modulation (QAM) and/or phase-shift keying (PSK) can be performed over at least one tone associated with the encoded symbols. Each user can transmit the encoded symbols to a receiving entity, where the receiving entity can decode each symbol received from the plurality of users to produce a distinguishable symbol for each user based on the unique spreading codes associated with each user.

Abstract: Aspects of the present disclosure provide an apparatus and techniques for wireless communication. A node (e.g., a BS or UE) may receive information regarding a configuration of at least one subframe for measuring mixed interference between the node and one or more nodes in a network. The configuration specifies a pattern for measuring reference signals by the node within the at least one subframe. The node may measure reference signals according to the pattern, and determine interference between the node and the one or more nodes, based on the measured reference signals.

Abstract: A UE or mobile entity in a wireless communication may assist network optimization by determining a location uncovered by a wireless network, generate a coverage hole detected message if one or more conditions associated with the uncovered location are satisfied, and determining a time to transmit the coverage hole detected message to a covered wireless network. The covered network may act on the message to add covered in a second network so that the second network covers the UE. In other aspects, a UE or mobile entity may detect cell congestion in a first cell and assist the network in offloading congestion from the congested cell. In other aspects, a UE or mobile entity may detect backhaul congestion on a first cell, and assist in offloading backhaul communication for the first cell via a second cell.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by an apparatus. A method includes sending signaling indicative of one or more power ratios, wherein each of the one or more power ratios is based on a transmit power for transmitting sounding reference signal (SRS) using a corresponding antenna and a receive power for receiving channel state information reference signal (CSI-RS) using the corresponding antenna, and wherein the one or more power ratios are associated with one or more antennas; sending a first CSI-RS; receiving a first SRS; receiving first channel state feedback (CSF) corresponding to the CSI-RS; and performing channel estimation based on the first CSF and the first SRS.
