Abstract: A method for determining a search space includes determining the number of downlink control information bits of each type of control channel currently required to be monitored by a UE. A temporary search space corresponding to the each type of control channel is determined according to a mapping relationship currently used by the UE. It is determined that an actual search space corresponding to a selected type of control channel is all or a part of CCEs of a union of temporary search spaces corresponding to all or a part of control channels with the same number of the downlink control information bits when the DCI bit number of one or more other control channels is the same as the DCI bit number of the selected type of control channel.

Abstract: A downlink control channel monitoring method includes determining a first search space (SS) set and a second SS set. The method also includes determining, based on a first priority of the first SS set and a second priority of the second SS set, whether to monitor a first physical downlink control channel (PDCCH) on a first downlink control channel candidate resource of the first SS set, and whether to monitor a second PDCCH on a second downlink control channel candidate resource of the second SS set. The first priority of the first SS set is equal to the second priority of the second SS set. The second PDCCH carries a power saving signal.
