METHOD AND APPARATUS FOR IMPROVING UPLINK PHASE TRACKING REFERENCE SIGNAL (PT-RS SIGNAL) AND COMMUNICATION DEVICE Russian patent published in 2024 - IPC H04W72/04 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication and relates to improving an uplink phase tracking reference signal (PT-RS signal). To this end, the method includes steps of: sending, by means of a network device, a pointing message to user equipment, wherein the pointing message comprises a plurality of pieces of indicating information on the PT-RS signal relating to a plurality of transmit/receive points (TRP), wherein indicating information on the PT-RS signal sent to the corresponding TRP, indicates a demodulation reference signal (DMRS) port associated with a corresponding PT-RS signal port. This solves the problem of the impossibility of binding the PT-RS signal to the DMRS signal port for different sources that cause CFE, interference when transmitting a PUSCH channel using a plurality of TRPs, which improves the quality of the system.

EFFECT: providing the accuracy of the calculated evaluation of the PT-RS signal, which in turn increases the efficiency of compensating for common phase errors (CPhE) and the quality of the system.
