摘要: Methods and apparatus are provided that may simplify and enhance the location of nodes in a network, including ED and mobile TPs, even if all or many of the nodes are mobile. The methods may be used to enable single TP positioning, and may be used to reduce synchronization error. The provided methods make use of smart reflectors having known location. By processing a combination of signals, which may include an original transmitted signal, and/or one or more reflected signals, the location of a receiving node can be determined. Media tagging may be employed to allow a receiver to detect the identity of the nearby reflectors (with known locations) and based on the identity determine the locations of the reflectors. Using this information, the receiving node can detect its location regardless of knowing the transmission source and/or location.

摘要: At a first User Equipment (UE) in a wireless communication network, signaling that is associated with a direct wireless communication link between the first UE and a second UE is received. Signaling indicative of an estimate of range between the first UE and the second UE, based on the received signaling, is transmitted to network equipment in the wireless communication network. According to another aspect of the present disclosure, signaling that is indicative of an estimate of range associated with such a direct wireless communication link is received, and signaling indicative of a prediction model and/or signaling indicative of a prediction from the prediction model is transmitted. The prediction model is for prediction of Line of Sight (LoS) status of communication links in the wireless communication network, and is based in part on the estimate of range.

摘要: Some embodiments of the present disclosure provide a user equipment (UE) having active device components and passive device components. Responsive to receiving downlink (DL) transmissions in time division duplexing (TDD) mode, the active device components perform DL decoding while the passive device components perform passive transmission of ACK/NACK data. Such passive transmission may involve encoding the ACK/NACK data in an altered version of received radio frequency (RF) signals and using so-called backscatter communications to reflect the received RF signals, with alteration, using the same frequency resources used to receive the DL transmissions.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: Methods and devices utilizing downlink channel measurements for customization of downlink positioning reference signals (DL PRs) are provided. A serving base station (BS) for a targeted device and one or more non-serving BSs transmit respective downlink reference signals (DL RSs) to the targeted device. The targeted device reports respective downlink channel measurement information for each BS based on the received DL RSs. The BSs each transmit a respective DL PRS to the targeted device for downlink positioning measurement, wherein the respective DL PRS for each BS is configured based in part on the respective downlink channel measurement information reported by the targeted device for that BS. This allows the DL PRS for each BS to be configured taking into account downlink channel conditions between the BS and the targeted device, which can potentially improve positioning measurement accuracy by improving reception of the DL PRS at the targeted device.
