14 Claims

1. A method for Physical Downlink Control Channel (PDCCH) monitoring, comprising:

transmitting a power-saving signaling that carries PDCCH monitoring indication information and monitoring indication information for cells to a User Equipment (UE), wherein the PDCCH monitoring indication information is used to indicate whether to change first PDCCH monitoring, the first PDCCH monitoring is the PDCCH monitored by the UE according to the configured search space, and the monitoring indication information for the cells is used to indicate a cell where the PDCCH monitoring needs to be performed,

wherein the PDCCH monitoring indication information comprises at least one of:

first indication information indicating whether to skip the first PDCCH monitoring;

second indication information indicating whether to skip the first PDCCH monitoring and indicating a next PDCCH monitoring occasion when the first PDCCH monitoring skipping has been indicated;

third indication information indicating whether to change a PDCCH monitoring periodicity and indicating to perform the PDCCH monitoring according to the changed PDCCH monitoring periodicity;

fourth indication information indicating whether to change the PDCCH monitoring periodicity and indicating the changed PDCCH monitoring periodicity or an index corresponding to the changed PDCCH monitoring periodicity;

wherein the monitoring indication information for the cells comprises at least one of:

fifth indication information indicating a first quantity of Secondary cells (Scells) where the monitoring is to be performed;

sixth indication information indicating information about the Scells where the monitoring is to be performed,

wherein when the monitoring indication information for the cells is the fifth indication information, the method further comprises:

configuring an Scell list of the first quantity of Scells for the UE through high layer signaling; or configuring a correspondence between different quantities of Scells and Scell lists for the UE through high layer signaling; or

selecting the first quantity of Scells from a plurality of Scells in accordance with a predetermined ranking algorithm.
