Abstract: Some embodiments of the present disclosure provide a manner to enabling high-resolution sensing, localization, imaging, and environment reconstruction capabilities in a wireless communication system. A radio frequency (RF) map of the environment includes coarse location and orientation information for at least one reflector and at least one targeted device of the wireless communication system. A fine sensing procedure may involve using the information in the RF map to carry out sensing in a more limited region of the environment. The second stage may employ a sensing signal configuration provided to at least one device to be sensed in the limited region, so that the at least one device may assist in the sensing.

Abstract: Some embodiments of the present disclosure provide a manner for sensing devices (UEs) to collaborate with base stations to sense an environment. The UEs may obtain observations based on sensing signals transmitted in the environment and provide the observations to a dedicated processing node. The processing node is configured to process the received observations to coherently combine the observations to generate an enhanced observation. In addition to distributing the sensing to multiple UEs, the processing of the observations may also be distributed.

Abstract: Some aspects of the present disclosure provide a transmission point (e.g., a base station) with an ability to enlist a user equipment to help sense an environment. The transmission point may configure the user equipment to use specific sensing hardware and specific sensing signal parameters, including bandwidth and duration. Furthermore, the transmission point may configure the user equipment to use specific resources to report sensing results to the transmission point.

Abstract: Some embodiments of the present disclosure relate to the selection of a waveform for an integrated communications and sensing (ICS) signal, where the waveform is suitable for both communication applications and sensing applications. In view of the sensing applications, the waveform selection can be, at least in part, adapted based on capabilities of hardware of nodes involved in the sensing applications. In view of the communication applications, the waveform selection can be, at least in part, adapted based on the extent to which data is to be embedded.

Abstract: Some embodiments of the present disclosure provide for use of a linear chirp signal as a basis for a sensing signal. Modification of the linear chirp signal by a signature function can allow a receiver of the sensing signal to determine an identity for a source of the sensing signal. Accordingly, upon processing the received sensing signal to obtain path parameter estimates, the receiver can direct a transmission of an indication of the path parameter estimates to the source of the sensing signal. Aspects of the present application relate to performing multi-node, multi-path channel estimation on the basis of processing the received sensing signal. Conveniently, the processing is performed with low complexity.

Abstract: Systems and methods for estimating locations of signal shadowing obstructions in a wireless communication network are disclosed. The method involves at a network equipment, receiving from User Equipments (UEs), an identification of neighboring UEs from which the UEs have received a reference signal via a non-line-of-sight (NLoS) sidelink transmission. The method also involves estimating locations of signal shadowing obstructions based on location information of UEs associated with the NLoS sidelink transmissions, and configuring communications between the network equipment and at least one UE based on an estimated location of at least one signal shadowing obstruction.

Abstract: Sparse reference signal-related signaling, for a wireless channel that is associated with multiple antenna ports, is communicated with a User Equipment (UE). The sparse reference signal-related signaling is consistent with a sparse signaling pattern. In an embodiment, the sparse signaling pattern includes reference signal-related signaling associated with each of the antenna ports, and has been determined based on previous reference signal-related signaling previously communicated with the UE or another UE. In another embodiment, the sparse reference signal-related signaling is consistent with a varying sparse signaling pattern that is based on previous reference signal-related signaling previously communicated with the UE or another UE.

Abstract: Network equipment receives, from a User Equipment (UE), an indication that the network equipment is to transition to sparse reference signaling for the UE, and the network equipment then transmits the sparse reference signaling to the UE. The sparse reference signaling is consistent with a sparse signaling pattern, which is determined at the UE based on previous reference signaling previously transmitted to the UE or another UE. At a UE, the sparse reference signaling is received from network equipment, and channel measurement and prediction are performed based on the received sparse reference signaling.

Abstract: A method for an apparatus comprises obtaining a frequency modulation parameter corresponding to a frequency change rate of a frequency-modulated subcarrier; generating an Orthogonal Frequency Division Multiplexing (OFDM) -based waveform signal comprising a plurality of frequency-modulated subcarriers, the plurality of frequency-modulated subcarriers modulated according to the obtained frequency modulation parameter; and outputting the OFDM-based waveform signal. A plurality of modulated symbols may be generated from a sequence of bits and the modulated symbols may be precoded, according to the frequency modulation parameter, to generate precoded symbols. The OFDM-based waveform signal may then be generated from the precoded symbols. A corresponding method for detecting and decoding the waveform signal is also provided.

Abstract: Some embodiments of the present disclosure provide a location management function that receives, from a sensor system, a sensing-based profile that includes a sensing-based observation of a UE and receives, from a communication system, a reference-signal-based observation of the UE. The location management function may derive, from the sensing-based observation, a position hypothesis and may determine, from the reference-signal-based observation, UE identity information for the UE. By processing the reference-signal-based observation in conjunction with the sensing-based observation, the location management function may determine an association between the sensing-based observation and the reference-signal-based observation. The location management function may then transmit, to the UE having the UE identity information determined from the reference-signal-based observation, an indication of the position hypothesis derived from the sensing-based observation.
