Original Abstract Submitted
The present disclosure relates to methods and apparatuses for physical uplink shared channel (PUSCH) repetition transmissions. One embodiment of the present application provides a user equipment (UE), including: a receiver that receives downlink control information (DCI) including a first indicator and a second indicator; and a processor that is coupled with the receiver. The first indicator includes a first bit and a second bit and indicates one or two phase tracking reference signal (PTRS)-demodulation reference signal (DMRS) associations between PTRS port(s) and DMRS port(s). The second indicator indicates whether a set of PUSCH repetition transmissions is transmitted according to sounding reference signal (SRS) resource(s) configured in a first SRS resource set, in a second SRS resource set, or in both the first SRS resource set and the second SRS resource set, and each PUSCH repetition transmission is transmitted according to SRS resource(s) configured in one of the first SRS resource set and the second SRS resource set. The processor determines a mapping relationship between the PTRS-DMRS association indicated by the first bit and/or the second bit of the first indicator and each PUSCH repetition transmission among the set of PUSCH repetition transmissions based on the first indicator and the second indicator.
