Measurement method, indication method, apparatus, terminal, network device, and medium

A terminal, comprising:

• a processor and a memory storing computer program instructions;
• wherein
• the computer program instructions, when executed by the processor, cause the terminal to perform:
• determining a demodulation reference signal (DMRS) of a physical downlink control channel (PDCCH) used for radio resource management (RRM) measurement;
• and
• performing RRM measurement according to the DMRS;
• wherein
• the DMRS used for the RRM measurement is determined according to higher layer signaling;
• and the computer program instructions, when executed by the processor, cause the terminal to further perform:
• determining, according to the higher layer signaling, whether the terminal is allowed to perform the RRM measurement according to the DMRS of the PDCCH;
• wherein the higher layer signaling comprises an indication of a synchronization signal block measurement timing configuration SMTC used for RRM measurement, and the DMRS for performing the RRM measurement comprises:
• a DMRS of a PDCCH associated with a synchronization signal block (SSB) comprised in a time window indicated by the SMTC, and/or
• the higher layer signaling comprises an indication of the SSB actually transmitted in the serving cell, and the DMRS for performing the RRM measurement comprises:
• a DMRS of a PDCCH associated with the SSB actually transmitted in the serving cell.

A network device, comprising:

• a processor and a memory storing computer program instructions;
• wherein the computer program instructions, when executed by the processor, cause the network device to perform:
• indicating a demodulation reference signal (DMRS) of a physical downlink control channel (PDCCH) used for radio resource management (RRM) measurement by a terminal;
• wherein
• the DMRS used for the RRM measurement is indicated by using higher layer signaling;
• and
• the method further comprises:
• indicating, by using the higher layer signaling, whether to allow the terminal to perform the RRM measurement according to the DMRS of the PDCCH;
• wherein the higher layer signaling comprises an indication of a synchronization signal block measurement timing configuration (SMTC) used for RRM measurement, and the DMRS for performing the RRM measurement comprises:
• a DMRS of a PDCCH associated with a synchronization signal block (SSB) comprised in a time window indicated by the SMTC;
• and/or
• the higher layer signaling comprises an indication of the SSB actually transmitted in the serving cell, and the DMRS for performing the RRM measurement comprises:
• a DMRS of a PDCCH associated with the SSB actually transmitted in the serving cell.
