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 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: 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.

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: A method and User Equipment (UE) for estimating locations of obstacles to signal transmission in a wireless communication network is disclosed. The method involves at the UE in communication with the network, in response to receiving a reference signal from a neighboring node via a non-line-of-sight (NLoS) transmission, transmitting an identification of the neighboring node to network equipment implementing the wireless communications network to facilitate estimating locations of the obstacles to signal transmission based on estimates of the location of the UE and the neighboring node.

摘要: 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.

摘要: 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.
