Claim 0:
1. A channel detection indication method, applied to a terminal and comprising:
obtaining at least two sets of configuration information, wherein the at least two sets of configuration information are related to monitoring a physical downlink control channel (PDCCH);
determining target configuration information from the at least two sets of configuration information; and
monitoring the PDCCH based on the target configuration information;
wherein the at least two sets of configuration information are predefined, or the at least two sets of configuration information are configured by a network device via radio resource control (RRC) signaling, the step of determining target configuration information from the at least two sets of configuration information comprises one of following:
based on downlink control information (DCI), selecting one set of configuration information that is indicated by the DCI, as the target configuration information, from the at least two sets of configuration information;
switching the target configuration information from first configuration information to second configuration information when a first trigger condition is met;
and
switching the target configuration information from the second configuration information to the first configuration information, when a second trigger condition is met,
wherein the second configuration information is different from the first configuration information, the first configuration information is one of the at least two sets of configuration information, and the second configuration information is one of the at least two sets of configuration information;
wherein the first trigger condition comprises:
a first PDCCH that carries a target DCI format is received, wherein the target DCI format is one of preset DCI formats; or
a second PDCCH that is scrambled by a target RNTI is received, wherein the target RNTI comprises at least one of a cell radio network temporary identifier (C-RNTI) and a configured scheduling radio network temporary identifier (CS-RNTI);
wherein the second trigger condition comprises one of the following:
a target PDCCH is not received in N time domain transmission units, wherein the target PDCCH carries a target DCI format, or the target PDCCH is scrambled by a target RNTI, wherein the target RNTI comprises at least one of a C-RNTI and a CS-RNTI; the time domain transmission unit comprises a slot, a mini-slot, a millisecond, or a time domain symbol, and N is a positive integer;
an inactivity timer of a DRX cycle expires in a discontinuous reception (DRX) scenario; and
a DRX common media access control control element (MAC CE) is received, and the MAC CE indicates entering an opportunity for DRX of a DRX cycle.
