Physical uplink shared channel transmission method and apparatus, and storage medium

A physical uplink shared channel (PUSCH) transmission method, wherein the method is performed by a network device, the network device supports simultaneous uplink transmission with multiple antenna panels (STxMPs), and the method comprises:

• determining that a PUSCH configuration uses a single frequency network (SFN) transmission mode;
• based on a first indication field in downlink control information (DCI), performing a single-transmission reception point (TRP) PUSCH reception or a multi-TRP PUSCH reception in the SFN transmission mode, wherein
• the single-TRP PUSCH reception comprises a PUSCH reception directed to a single antenna panel via a single TRP,
• the multi-TRP PUSCH reception in the SFN transmission mode comprises a PUSCH reception directed to different TRPs respectively via multiple antenna panels in the SFN transmission mode, and
• the first indication field is used to indicate an association between a second indication field and a sounding reference signal (SRS) resource set in the SFN transmission mode, and an association between the second indication field and at least one of a TRP or a transmission configuration indicator (TCI) state in the SFN transmission mode.

A communication device, comprising:

• a processor;
• and
• a memory for storing instructions being executable by the processor,
• wherein the processor is configured to call the instructions stored in the memory to perform a physical uplink shared channel (PUSCH) transmission method, wherein the communication device supports simultaneous uplink transmission with multiple antenna panels (STxMPs), and the method comprises:
• determining that a PUSCH configuration uses a single frequency network (SFN) transmission mode;
• and
• based on a first indication field in downlink control information (DCI), performing a single-transmission reception point (TRP) PUSCH transmission or a multi-TRP PUSCH transmission in the SFN transmission mode, wherein
• the single-TRP PUSCH transmission comprises a PUSCH transmission directed to a single TRP via a single antenna panel,
• the multi-TRP PUSCH transmission in the SFN transmission mode comprises a PUSCH transmission directed to different TRPs respectively via multiple antenna panels in the SFN transmission mode, and
• the first indication field is used to indicate an association between a second indication field and a sounding reference signal (SRS) resource set in the SFN transmission mode, and an association between the second indication field and at least one of a TRP or a transmission configuration indicator (TCI) state in the SFN transmission mode.
