Abstract: The present disclosure provides methods and apparatuses for multi-carrier transmissions over adjacent channels that reduce self-jamming due to asymmetric interference. In an aspect, a large bandwidth load-base equipment (LBE) carrier may be provided such that CCA is performed jointly over the entire bandwidth. In another aspect, additional CCA timeslots may be used to synchronize the two carriers. In a further aspect, an extended CCA may be performed on a primary unlicensed carrier while a simple CCA may be performed on a secondary unlicensed carrier. In yet another aspect, LBE may be deployed on some carriers while frame-base equipment (FBE) may be deployed on other carriers.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via first frequency ranges and first time periods, a plurality of sidelink control blocks that each indicate a sidelink positioning reference signal burst pattern for one or more sidelink UEs. The UE may receive, within a second frequency range and during a second time period, a plurality of multiplexed sidelink positioning reference signals from the one or more sidelink UEs in accordance with the sidelink positioning reference signal burst patterns. The UE may determine a position of the UE based at least in part on the receiving of the plurality of multiplexed sidelink positioning reference signals.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

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.
