Abstract
Presented are systems and methods for indicating phase tracking reference signal-demodulation reference signal (PTRS-DMRS) association. A wireless communication device may receive a scheduling grant to trigger a first group of physical uplink shared channel (PUSCH) transmission occasions and a second group of PUSCH transmission occasions from a wireless communication node. The scheduling information carried by the scheduling grant may at least include port association information of PTRS-DMRS. The port association information may comprise a first port association for the first group of PUSCH transmission occasions and a second port association for the second group of PUSCH transmission occasions. The second port association may be at least associated with a portion of the scheduling information which is at least for the first group of PUSCH transmission occasions.
