1. A method for controlling channel monitoring, comprising:
determining physical downlink control channel (PDCCH) monitoring scheme indication information; and
sending the PDCCH monitoring scheme indication information to one or more terminals for indicating the one or more terminals to adjust a PDCCH monitoring scheme, via adding a new bit field to a downlink control information (DCI) format;
wherein the PDCCH monitoring scheme indication information comprises indication information of a combination of following functions:
function 1: an indication of whether to skip a next or a plurality of subsequent PDCCH monitoring occasions;
function 3: an indication of a cycle of a PDCCH monitoring occasion;
function 4: an indication of a control resource set (CORESET) where a PDCCH monitoring occasion is located;
function 5: an indication of a monitoring pattern of a PDCCH monitoring occasion;
function 6: an indication of a PDCCH monitoring aggregation level and/or a quantity of PDCCH candidates per PDCCH monitoring occasion aggregation level; and
function 7: an indication of monitoring a duration of consecutive slots where a PDCCH search space is located;
wherein the DCI format is DCI format 1_1 or DCI format 1_0 or DCI format 2_6; and the new bit field corresponds to joint coding of the function 1 and the function 3 to the function 7.
