Abstract
Embodiments of the present disclosure relate to a method and apparatus for multiple transmit-receive points (multi-TRP) transmission. According to an embodiment of the present disclosure, a method can include: receiving first configuration information for uplink phase tracking reference signal (PT-RS) and second configuration information indicating a plurality of sounding reference signal (SRS) resource sets, wherein each of the plurality of SRS resource sets is associated with at least one physical uplink shared channel (PUSCH) repetition; for each PUSCH repetition, determining a number of PT-RS ports for transmitting the uplink PT-RS; and transmitting two or more PUSCH repetitions. Embodiments of the present disclosure can resolve the issues caused by the imbalance numbers of PT-RS ports between different TRPs.
