Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK PHASE TRACKING REFERENCE SIGNAL FOR NETWORK COOPERATIVE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/154539
Kind Code:
A1
Abstract:
According to present disclosure, there is provided a method for repetitive transmitting physical uplink shared channel (PUSCH) to a multiple transmission and reception point (mTRP) performed by a user equipment (UE). The method comprises receiving, from a base station, downlink control information (DCI) including phase tracking reference signal (PTRS) - demodulation reference signal (DMRS) association information; based on the PTRS-DMRS association information, determining PTRS port for each sounding reference signal (SRS) resource set among a plurality of SRS resource set; and based on the determined PTRS port, transmitting PTRS.
