Abstract

Disclosed in the present invention are a method, equipment and an apparatus for indicator and downlink control channel detection, comprising: determining data which must be transmitted to a terminal in one or more transmission time intervals by means of a downlink control channel; a base station sending a command to the terminal, used to indicate that the terminal determine according to the command whether it is necessary to detect a downlink control channel in the one or more transmission time intervals. On the terminal, determining according to the command whether it is necessary to detect a downlink control channel in the one or more transmission time intervals. After using the present invention, when a base station has not scheduled a terminal, this objectively causes a terminal side to not have excess power consumption, and lowers terminal-side power consumption.

wherein the indicator information is realized through independent coding; or the indicator information is processed in a same manner as a downlink control channel and transmitted in a PDCCH channel structure.

3. The method according to claim 2 , wherein the signaling is indicator information sent at a specific resource location that is configured by a base station for a terminal by using higher layer signaling.

4. A method for indicating downlink control channel detection, comprising:

determining data that needs to be transmitted to a terminal within one or more TTIs by using a downlink control channel; and

sending, by a base station, signaling to the terminal, to indicate the terminal to determine, according to the signaling, whether a downlink control channel needs to be detected within one or more TTIs;

wherein the signaling is indicator information carried by a group common PDCCH; wherein the indicator information carried by a group common PDCCH is N-bit indicator information, and N is a positive integer greater than or equal to 1;

when N=1, under a condition that the indicator information is in a state 1, the indicating the terminal to detect a downlink control channel within one or more TTIs; or under a condition that the indicator information is in a state 0, indicating the terminal not to detect a downlink control channel within one or more TTIs;

or when N>1, using each bit of the N-bit information to indicate whether a downlink control channel in a corresponding TTI of TTIs needs to be detected, the each bit of the N-bit information corresponds to one of TTIs and used for indicating whether a downlink control channel in the one of TTs needs to be detected.

5. The method according to claim 4 , wherein the signaling is indicator information sent at a specific resource location;

wherein when the signaling is indicator information sent at a specific resource location, detecting the indicator information on the specific resource within each TTI or every M TTIs, to determine whether a downlink control channel needs to be detected, wherein M is an integer greater than 1; the TTI is a slot or a mini-slot;

wherein the indicator information is realized through independent coding; or the indicator information is processed in a same manner as a downlink control channel and transmitted in a PDCCH channel structure.

6. The method according to claim 5 , wherein the signaling is indicator information sent at a specific resource location that is configured by a base station for a terminal by using higher layer signaling.

7. A user equipment, comprising:
