Abstract: Systems and methods for determining round trip time (RTT) includes a second node, which receives a first signal from a first node at a first time, determines a timing advance based on a first estimated channel response for the first signal, and transmits at a second time, a second signal to the first node, wherein the second time occurs after the first time by an amount of a pre-specified delay for RTT estimation minus the timing advance. The first node transmits the first signal to the second node at an initial time, receives the second signal from the second node, and determines a timing statistic from a second estimated channel response for the second signal, the timing statistic estimated at a third time. The first node determines the RTT as the third time minus the initial time minus the pre-specified delay for RTT estimation.

Abstract: Disclosed are techniques for computing and reporting a relevance metric for a positioning beacon beam. In an aspect, a first node receives, from a second node, a plurality of beams, determines a relevance metric for each of one or more beams of interest from the plurality of beams, wherein the relevance metric for each beam of the one or more beams of interest is based on a time of arrival at the first node of the beam and a signal strength of the beam, and sends, to the second node, a report identifying each of the one or more beams of interest and including the relevance metric for each of the one or more beams of interest.

Abstract: A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

Abstract: Techniques for centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may identify a UE located within coverage of a femto cell but unable to access the femto cell due to restricted association. The designated network entity may deactivate the femto cell to allow the UE to communicate with another cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may identify a set of resource elements on which to transmit a reference signal based at least in part on a numerology being used by the transmitter and at least one of a maximum system numerology or a minimum system numerology; and transmit the reference signal on the identified set of resource elements. In some aspects, a receiver may identify a set of resource elements from which to obtain a reference signal based at least in part on a numerology being used by the receiver and at least one of a maximum system numerology or a minimum system numerology; and obtain the reference signal from the identified set of resource elements. Numerous other aspects are provided.

Abstract: Disclosed are techniques to determine angle of departure (AoD) of signals transmitted from a set of transmission points associated with a transmitter (e.g., a base station, a user equipment (UE)). In an aspect, the set of transmission points are collocated and transmit coherent signals. A receiver (e.g., UE, network entity) determines phase difference of arrivals (PDoAs) of the signals. Based on the PDoAs and locations of the set of transmission points, the AoD can be calculated. When the UE is the receiver, the network entity can send a base station almanac (BSA) message to the UE indicating the set of transmission points and their locations.

Abstract: Disclosed are techniques for transmitting and processing reference signals for positioning estimation over a multipath multiple-input multiple-output (MIMO) channel. In aspects, a first node configures first and second reference signal resource sets for transmission of first and second sets of reference signals, wherein the first and second reference signal resource sets occur on first and second subbands of, and/or during first and second time intervals on, the MIMO channel, wherein each reference signal resource in the first and second reference signal resource sets utilize at least first and second MIMO precoders, and transmits, to a second node over the MIMO channel, the first and second sets of reference signals, wherein the first node transmits the first and second sets of reference signals to assist the second node to perform a positioning measurement based on joint processing of the first and second sets of reference signals.

Abstract: Aspects of the disclosure relate to methods and an apparatus for transmitting a signal in a multi-layer hybrid resource spread multiple access (RSMA) system. A non-orthogonal multiple access (NOMA) user equipment (UE) demultiplexes a stream of bits into a plurality of layers, encodes each layer with a different coding rate, modulates each layer of encoded bits with a different modulation scheme, and spreads and scrambles each layer of modulated symbols with a different spreading code and a corresponding different scrambling code. Thereafter, the NOMA UE permutes the plurality of layers having spread and scrambled symbols into a plurality of interleaved layers, scales and phase rotates each interleaved layer with a different scaling factor and a corresponding different phase rotating factor, sums the scaled and phase rotated symbols, maps the summed symbols onto a set of allocated resources, and transmits the mapped symbols via the set of resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a resource spread multiple access scheme is enabled, wherein the bit and/or symbol level resource spreading happens in time and/or frequency domain through bits or symbol level repetition and spreading. Furthermore, the UE may process bits of codewords and modulated symbols using a set of spreading sequences and a set of scrambling sequences. The UE may transmit the modulated symbols with a discrete-Fourier-transform (DFT)-spread (DFT-s) waveform based at least in part on processing the modulated symbols using the set of spreading sequences and the set of scrambling sequences. Numerous other aspects are provided.
