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.

Abstract: Methods and apparatus are provided for integrated communication and sensing. For example, an electronic device may transmit a radio frequency (RF) pulse signal in the active phase of a periodic sensing cycle, and sense in the passive phase of the sensing cycle, a reflection of the RF pulse signal reflected from an object. The RF pulse signal is defined by a waveform for carrying communication data between electronic devices. The sensed RF pulse signal is at least a portion of the transmitted or reflected RF pulse signal, wherein the portion is equal to or greater than a threshold value for the object being within a sensing range of the first electronic device. The electronic device may also receive a communication signal from another electronic device during the passive phase.

Abstract: Some embodiments of the present disclosure provide a transmit point that transmits a downlink chirp sensing waveform (DL CSW) signal. A device receives the DL CSW signal and obtains a cloned chirp sensing waveform. The cloned chirp sensing waveform includes a parameter that can be uniquely associated with the device. The device transmits a UL cloned CSW signal based on the cloned chirp sensing waveform. The transmit point receives the UL cloned CSW signal and processes the UL cloned CSW signal to estimate a pose for the device and associate the estimated pose with the identity of the device.

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: 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: Aspects of the present disclosure relate to integration of sensing and wireless communications. Wireless communication networks can configure and implement both sensing signals and communication signals. Sensing signals, or sensing reference signals, can be used to determine properties of the environment, and do not carry any information or data for the purpose of communications. Communication signals, on the other hand, are signals that carry information or data between network entities. Sensing agents can be used for both passive and active sensing. Sensing agents may be dedicated devices capable of performing passive sensing, active sensing, or both. Sensing agents can also be existing networks device such as user equipment or transmit receive points. Methodologies described here may be particularly beneficial for half-duplex systems, but could also be implemented in full duplex systems.

Abstract: A bit-level operation may be implemented prior to modulation and resource element (RE) mapping in order to generate a NoMA transmission using standard (QAM, QPSK, BPSK, etc.) modulators. In this way, the bit-level operation is exploited to achieve the benefits of NoMA (e.g., improved spectral efficiency, reduced overhead, etc.) at significantly less signal processing and hardware implementation complexity. The bit-level operation is specifically designed to produce an output bit-stream that is longer than the input bit-stream, and that includes output bit-values that are computed as a function of the input bit-values such that when the output bit-stream is subjected to modulation (e.g., m-ary QAM, QPSK, BPSK), the resulting symbols emulate a spreading operation that would otherwise have been generated from the input bit-stream, either by a NoMA-specific modulator or by a symbol-domain spreading operation.

Abstract: A diversity channel for data transmission is obtained by communication equipment. The diversity channel indicates communication resources that are assigned to the communication equipment, and is from a set of diversity channels that are consistent with codewords of a linear code. The communication equipment also transmits a data transmission using the communication resources indicated by the diversity channel. The diversity channel assignment could be determined, by network equipment for example, and information that identifies the diversity channel could be transmitting to the communication equipment. Such information could be explicitly or implicitly signaled to the communication equipment. A set of diversity channels could be generated directly as codewords of one or more linear codes, or additional operations could be applied to such codewords, and possibly other information that is not generated using a code, to provide a diversity channel set.

Abstract: Methods and systems are disclosed for symbol sequence generation and transmission for non-orthogonal multiple access (NoMA) transmission. A NoMA signal may be generated based on: (1) a first symbol sequence, the first symbol sequence determined from a set of input bits and associated with a first MA signature within a first MA signature space; (2) a second symbol sequence determined based on the first symbol sequence, the second symbol sequence being associated with a second MA signature within a second MA signature space; and (3) a symbol-to-resource element mapping applied to the second symbol sequence to produce the NoMA signal.

Abstract: User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.
