Aspects of the present disclosure relate to identifying points of interest by generating and storing virtual geofence information that is captured around a physical structure based in part on global positioning system (GPS) data from a plurality of devices that is then processed to identify GPS trajectory and kernel density estimation. Specifically, the techniques include receiving, at the network-based control computer, GPS data from a plurality of devices and grouping the GPS data from the plurality of devices to generate GPS trajectory information for each group of the plurality of devices. Based on the GPS trajectory information, the network-based control computer may calculate kernel density estimation and determine an isoline on a virtual map for the each group of the plurality of devices. By overlaying the isoline data on a geographic coordinate information of a physical structure, the network-based control computer may generate a virtual geofence around the physical structure and store, in a memory, geofence information for the facility.

The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include one or more of a direction, a velocity, a location confidence and a location of the responder UE.

The present disclosure relates to the field of communication, and provided therein are a feedback sequence transmission method. The method comprises: determining, by a receiving terminal, a physical-resource location adopted by a feedback terminal when the feedback terminal sends the feedback sequence, based on a feedback characteristic of the feedback terminal; and receiving, by the receiving terminal, the feedback sequence at the physical-resource location corresponding to the feedback terminal.

Positioning for user equipments (UEs) in a wireless network is supported by restricting position reference signal (PRS) configuration parameters for a Transmission Reception Point (TRP) based on PRS configuration used by co-located TRPs. The PRS configuration parameters for the TRP may be restricted by restricting orthogonality of the PRS resources with respect to PRS resources from co-located TRPs to only code division multiplexing, and other types of orthogonality such as time division multiplexing and frequency divisional multiplexing are not permitted for co-located TRPs. The PRS configuration parameters for the TRP may be restricted to the same muting sequence type, e.g., inter-instance and/or intra-instance muting, as used by co-located TRPs. The PRS configuration parameters, e.g., related to orthogonality and/or muting, are not restricted with respect to non-co-located TRPs. The restrictions on the PRS configuration parameters for a TRP may be determined by a central authority, such as a location server.
