Abstract
A communication device of a communications network can determine a reception-transmission (“Rx-Tx”) time difference between a pair of signals communicated with a network node of the communications network. The communication device can transmit a message to the network node, the message including an indication of the Rx-Tx time difference.
Claims26
A method of operating a communication device of a communications network, the method comprising:
- determining a reception-transmission, Rx-Tx, time difference between a pair of signals communicated with a network node of the communications network;
- and
- transmitting a message to the network node, the message comprising an indication of the Rx-Tx time difference.
A method of operating a network node of a communications network, the method comprising:
- receiving a uplink, UL, reference signal, RS, from a communication device of the communications network;
- transmitting a downlink, DL, RS to the communication device;
- determining a first reception-transmission, Rx-Tx, time difference indicating an amount of time between receiving the UL RS and transmitting the DL RS;
- responsive to a criteria being met, receiving a message from the communication device, the message comprising an indication of a second Rx-Tx time difference indicating an amount of time between the communication device transmitting the UL RS and receiving the DL RS;
- and
- determining a propagation delay based on the first Rx-Tx and the second Rx-Tx.
