Title:
MESSAGE TRANSMISSION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/083170
Kind Code:
A1
Abstract:
Disclosed in the present application are a message transmission method and a communication apparatus. The message transmission method comprises: receiving a message 4, wherein a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) carrying the message 4 has a quasi co-location (QCL) relationship with a first synchronization signal block (SSB) of at least two SSBs, which are SSBs corresponding to multiple repeated transmissions of a message 1, or, the DMRS of the PDSCH carrying the message 4 has the same QCL relationship with a reference signal of a PDSCH carrying a message 2, or, the DMRS of the PDSCH carrying the message 4 has the same QCL relationship with a reference signal of a physical uplink shared channel (PUSCH) carrying a message 3. By using the present application, a signal with a QCL relationship with the DMRS of the PDSCH carrying the message 4 can be determined in a scenario involving repeatedly transmitting the message 1 multiple times.
