Abstract
Disclosed by the present application are an energy-saving indication method and an apparatus thereof. In the present application, a base station determines a terminal that needs to wake up; and when there is a terminal needs to wake up, in a PDCCH detection opportunity configured for the terminal, the base station sends wake-up indication information to the terminal by means of a PDCCH. In the PDCCH detection opportunity configured for the terminal, the terminal receives by means of the PDCCH the wake-up indication information sent by the base station, and performs PDCCH detection according to the wake-up indication information.
Claims16
An energy-saving indication method, comprising:
- determining, by a base station, a terminal needing to wake up or to sleep in a terminal group;
- and
- sending, by the base station through a physical downlink control channel (PDCCH), wake-up indication information and indication information of resource information configured for one or more terminals needing to wake up in the terminal group to the terminal needing to wake up in the terminal group on PDCCH monitor occasions configured for the terminal, wherein the wake-up indication information instructs the terminal to wake up;
- or sending, by the base station through the PDCCH, Go-To-Sleep (GTS) indication information to the terminal needing to sleep in the terminal group on the PDCCH monitor occasions configured for the terminal group, wherein the GTS indication information instructs the terminal to sleep;
- wherein the method further comprises:
- sending, by the base station through the PDCCH, first downlink control information (DCI) and second DCI to the terminals in the terminal group;
- wherein
- the first DCI comprises a first information field, the first information field comprises a plurality of subfields, each of the plurality of subfields corresponds to one or more terminals in the terminal group, a value of a subfield to which the terminal needing to wake up corresponds is equal to a value of the wake-up indication information, and a value of a subfield to which the terminal needing to sleep corresponds is equal to a value of the GTS indication information;
- and
- the second DCI comprises a second information field, the second information field comprises a plurality of subfields, a quantity of the plurality of subfields comprised in the second information field is smaller than or equal to a quantity of the one or more terminals needing to wake up in the terminal group, each subfield in the second information field corresponds to one or more terminals needing to wake up in the terminal group, and the each subfield is configured to carry the indication information of resource information configured for the one or more terminals needing to wake up.
