Abstract
Techniques are provided for managing positioning reference signals in communication networks. A method of measuring downlink positioning reference signals includes transmitting one or more uplink positioning reference signals, receiving downlink positioning reference signal configuration information associated at least in part with the one or more uplink positioning reference signals, and measuring one or more downlink positioning reference signals based at least in part on the downlink positioning reference signal configuration information.
Claims28
A method of measuring downlink positioning reference signals, comprising:
- transmitting one or more uplink positioning reference signals via one or more corresponding transmission beams;
- receiving downlink positioning reference signal configuration information including beam pairing information and schedule information configured to remove incompatible downlink positioning reference signals based at least in part on measurements of the one or more uplink positioning reference signals and the one or more corresponding transmission beams obtained by one or more wireless nodes;
- and
- measuring one or more downlink positioning reference signals based at least in part on the downlink positioning reference signal configuration information.
A method of providing downlink positioning reference signals, comprising:
- receiving one or more uplink positioning reference signal measurement values associated with a user equipment from one or more wireless nodes, wherein the one or more uplink positioning reference signal measurement values were received via one or more corresponding transmission beams;
- determining a downlink positioning reference signal configuration including beam pairing information and schedule information configured to remove incompatible downlink positioning reference signals based at least in part on the one or more uplink positioning reference signal measurement values and the one or more corresponding transmission beams obtained by the one or more wireless nodes;
- and
- providing the downlink positioning reference signal configuration to the one or more wireless nodes.
An apparatus, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, and configured to:
- transmit one or more uplink positioning reference signals via one or more corresponding transmission beams;
- receive downlink positioning reference signal configuration information including beam pairing information and schedule information configured to remove incompatible downlink positioning reference signals based at least in part on measurements of the one or more uplink positioning reference signals and the one or more corresponding transmission beams obtained by one or more wireless nodes;
- and
- measure one or more downlink positioning reference signals based at least in part on the downlink positioning reference signal configuration information.
