Abstract: Systems, methods, and apparatuses for detecting interference caused by a wireless local area network (WLAN) and a wireless wide area network (WWAN) node operating in an unlicensed or shared spectrum is disclosed. In accordance with the present disclosure, a base station may generate a null tone pattern for one or more subframes transmitted to the UE. The null tone pattern may include one or more null tones mapped to consecutive symbols in each resource block to detect interference. Accordingly, a UE may monitor a wireless channel from a base station for a null tone transmission. The UE may detect a null tone pattern by decoding a known physical layer channel to identify the null tone pattern. In some aspects, the UE may generate channel estimates, decode allocated resources, determine timing of future transmissions and/or establish communication with the base station based on the identified null tone pattern.

Abstract: The disclosure provides for a method of interference detection using adaptive energy detection in unlicensed spectrum. The method can include a first modem operating according to a first radio access technology (RAT) receiving a message from a network entity operating according to the first RAT. The first modem sends a detected energy level value to a second modem that is using a second RAT, where the detected energy level value is based at least on the measured energy level of the received message. The second modem adjusts an energy detection threshold based on the detected energy level value received from the first modem. In an aspect, the first modem receives messages from a plurality of network entities operating according to the first RAT, where the detected energy level value is determined based on measured energy levels of the plurality of received messages.

Abstract: Disclosed are techniques for wireless signaling. In an aspect, a user equipment (UE) transmits, to a network component, an indication of a capability to estimate a carrier frequency offset (CFO) of the UE associated with radio frequency for sensing (RF-S) operations. In another aspect, the network component estimates the CFO of the UE (e.g., based on measurement information from the UE and/or wireless node(s)). In some designs, the network component further transmits, to the UE, the CFO of the UE (e.g., for CFO compensation associated with RF-S sensing operation(s)).

Abstract: A user equipment (UE) may receive a configuration for collecting measurements to at least one of train or verify a positioning model. The UE may receive a set of positioning signals. The UE may measure the set of positioning signals. The UE may output a subset of the measured set of positioning signals to at least one of train or verify the positioning model based on the configuration. The UE may output the subset of the measured set of positioning signals by training verifying the positioning model at the UE based on the subset of the measured set of positioning signals, or by transmitting the subset of the measured set of positioning signals to at least one of train or verify the positioning model.

Abstract: Support for user equipment (UE) positioning with a non-terrestrial network (NTN) considers the significantly different propagation delays of positioning signals transmitted by SVs (SVs) in different orbits and elevation angles. The UE may be configured with a discontinuous measurement gap set for each positioning occasion, including separate measurement gaps for positioning signals transmitted by different SVs. Prioritization based on expected reference signal time differences (RSTD) may be used so that positioning signals received by the UE at nearly the same time are measured with higher priority. A burst configuration based on orbital position of SVs may be used so that positioning signals from different SVs will arrive at the UE within a maximum time window. The UE may provide a capability message indicating a maximum search window and uncertainty supported for NTNs, which may be used to configure the positioning signals to be measured by the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity may receive guard band information from each of a plurality of transmission/reception points (TRPs), wherein the guard band information describes guard bands used by that TRP. The network entity may generate assistance data, the assistance data comprising the guard band information for each of the plurality TRPs, wherein the guard band information defines at least one guard band between resource block (RB) sets within a bandwidth part (BWP), and wherein each guard band occupies zero or more contiguous RBs of the BWP. The network entity may send the assistance data to at least one user equipment (UE). In an aspect, the UE may then process positioning reference signals (PRSs) received from each of the plurality of TRPs according to the guard band information for that TRP.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless node establishes sidelink connections with a set of UEs. The wireless node transmits, to a network component, a request for sidelink resources for a sidelink position estimation procedure associated with the set of UEs. The network component determines an available sidelink resource pool for the sidelink position estimation procedure in response to the request. The network component transmits, to the wireless node in response to the request, an indication of the available sidelink resource pool for the sidelink position estimation procedure. The wireless node transmits, to each UE in the set of UEs, a sidelink resource configuration that is based on the available sidelink resource pool for the sidelink position estimation procedure.
