An antenna control method, communications positioning apparatus and computer storage medium is provided. The method is used in a communications positioning apparatus. The communications positioning apparatus comprises a communications antenna and a rotation device. The communications antenna comprises at least two antennas. The rotation device drives the communications antenna to rotate, wherein the method comprises: acquiring a first command, wherein the first command turns on a positioning mode; in response to the first command, acquiring angle information corresponding to the communications antenna and a beacon; in accordance with the angle information, determining corresponding rotation parameters of the rotation device, wherein the rotation parameters comprise at least a rotation direction and a rotation angle; and in accordance with the rotation parameters, controlling the rotation device to drive the rotation direction and rotation angle corresponding to the communications antenna.

Disclosed embodiments facilitate combining a plurality of wireless signal measurement sets with displacement measurements within some time interval of a position request to determine a User Equipment (UE) position. A first set of wireless signal measurements may be obtained from a first set of base stations at a first time at a first location. Subsequently, a second set of wireless signal measurements from a second set of base stations may be obtained at a second time at a second location distinct from the first location. A displacement measurement (e.g .a displacement vector) between the first location and the second location may be obtained. The position of the UE at the second location may then be determined based on the first and second sets of wireless signal measurements and the displacement measurement. In some embodiments, the first and second sets of wireless signal measurements may each be deficient measurement sets.

Systems, methods, and other embodiments associated with reflectors are described. One example system comprises a collection antenna. The system also comprises a reflector configured to reflect a designated signal to the collection antenna and configured to reflect a non-designated signal away from the collection antenna.

A system for determining location information for a wireless device is described. The system includes a UE, a LE and multiple LMUs. The LE sends, to the LMUs, reception instructions with characteristics of the signal transmission from the UE and each LMU receives, from the LE, the reception instructions. The UE sends a signal transmission. Each LMU receives the transmitted signal from the UE, determines locating information based at least in part of the received signal and sends the locating information to the LE. The LE receives the locating information regarding the transmitted signal and determines a location of the UE based at least in part on the received locating information. Methods, apparatus and computer readable media are also described.
