Enhancing Uplink Measurements for Positioning by Adaptively Using Multi-Antenna Systems

摘要

Techniques and devices for improving uplink positioning techniques are described. An example method, implemented in a first node in a wireless communications network, begins with obtaining multi-antenna configuration information or multi-antenna capability data, or both, for a second node in the wireless communications network. The node carrying out the node may be a radio base station, a measuring node, or a wireless device to be positioned, in various embodiments. In some embodiments, the second node is a measuring node. In others, the second node is the wireless device to be positioned. The method continues with adapting a multi-antenna configuration of the wireless device for one or more transmissions to be measured for positioning purposes, or adapting a multi-antenna configuration of the measuring node for one or more positioning measurements, or both. The adapting is based on the obtained multi-antenna configuration information or multi-antenna capability data, or both.
