METHOD AND APPARATUS FOR PERFORMING DAS-BASED POSITIONING
Proposed is an operation method for a first device (100) in a wireless communication system. The method may comprise the steps of: receiving a first positioning reference signal (PRS) from a second device (200), on the basis of a first antenna (106-1), a second antenna (106-2), and a third antenna (106-3); obtaining a first time difference, on the basis of a first reception time at which the first PRS is received on the basis of the first antenna (106-2) and a second reception time at which the first PRS is received on the basis of the second antenna (106-2); obtaining a second time difference, on the basis of a third reception time at which the first RPS is received on the basis of the third antenna (106-3) and the first reception time; and obtaining the location of the first device (100), on the basis of the first time difference and the second time difference.
SYSTEM FOR RECOGNIZING THE LOCATION OF AN OBJECT AND METHOD THEREOF
A system for recognizing the location of a subject, comprises a server, signal transceivers, and a tracking device. The server transmits a request and stores a map file. The signal transceivers respectively communicate with the server to receive the request, and broadcast a reference signal to the other signal transceivers. The tracking device bidirectionally communicates with the signal transceivers, and periodically sends a tracking signal. After each of the signal transceivers obtains the first received signal strength indicator corresponding to the received reference signal and the second received signal strength indicator corresponding to the received tracking signal, each transmits the first signal strength indicator and the second signal strength indicator to the server. The server determines relative position information for the at least one tracking device within the map file according to the first signal strength indicators, the second signal strength indicators, and location information from the signal transceivers
SPATIAL DOMAIN MEASUREMENTS FOR BEAM BASED POSITIONING
Various example embodiments relate to positioning of a target node. A positioning report may comprise positioning assistance measurements from the target node and at least one anchor node, wherein the positioning assistance measurements are associated with angular differences between a pair of uplink and/or downlink transmission and/or reception beam directions. Apparatuses, methods, and computer pro-grams are disclosed.
Sound source distance estimation
An apparatus for generating at least one distance estimate to at least one sound source within a sound scene comprising the least one sound source, the apparatus configured to: receive at least two audio signals from a microphone array located within the sound scene; receive at least one further audio signal associated with the at least one sound source; determine at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source; determine a distance estimate to the at least one sound source based on the at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source.
DEVICE AND METHOD TO IMPROVE HORIZONTAL AND VERTICAL POSITIONING ACCURACY
User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.
POSITIONING IN BEAMFORMED COMMUNICATIONS
Methods, systems, and devices for wireless communication are described. A base station may receive a first measurement report from a user equipment (UE) that includes an indication of a measurement parameter associated with a first beamformed reference signal. The base station may receive additional measurement reports from the UE for additional base stations. The additional measurement reports may include an indication of measurement parameters associated with additional beamformed reference signals transmitted by the additional base stations. The base station may identify a location of the UE based on the first measurement report and the additional measurement report. Alternatively, the UE may transmit multiple beamformed sounding reference signals to multiple base stations, and a single base station may identify a location of the UE based on multiple reports collected from the multiple base stations.
Sidelink ranging and multilateration
A transceiver for a wireless communication system is configured to: communicate with at least one other transceiver of the system using a sidelink resource pool of the system; transmit signals on resources of the pool that are allocated to the transceiver on a period basis with equal length periods t.sub.periodA; transmit a first signal on a first resource of the resources allocated to the transceiver, and receive a second signal from another transceiver of the system on a second resource, the second signal being transmitted by the other transceiver responsive to a reception of the first signal, the second signal being transmitted by the other transceiver on the second resource using the period t.sub.periodA based on which the resources are allocated to the transceiver; determine a distance to the other transceiver based on a time t.sub.roundA between the transmission of the first signal and the reception of the second signal from the other transceiver, and based on the period t.sub.periodA based on which the resources are allocated to the transceiver.
