US 2022/0286966 A1 · ENERGY-SAVING INDICATION METHOD AND APPARATUS THEREOF

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. In the present application, wake-up and sleep signals are effectively sent, downlink control signaling transmission efficiency is improved, and the processing complexity of the base station is reduced.

Dependent claims

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 to the terminal needing to wake up in the terminal group on PDCCH monitor occasions configured for the terminal, 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 wake-up indication information instructs the terminal to wake up, and the GTS indication information instructs the terminal needing to sleep to sleep.

1 more element

An energy-saving indication method, comprising:

receiving, by a terminal through a physical downlink control channel (PDCCH), wake-up indication information or Go-To-Sleep (GTS) indication information sent by a base station on PDCCH monitor occasions configured for the terminal;
and
performing, by the terminal, PDCCH monitoring according to the wake-up indication information, or giving up, by the terminal, PDCCH monitoring in following one or more DRX cycles according to the GTS indication information.

A communication apparatus, comprising;

a processor, a memory and a transceiver, wherein the processor is configured to read a computer instruction in the memory to execute:
determining a terminal needing to wake up or to sleep in a terminal group;
and
sending, through the transceiver and a physical downlink control channel (PDCCH), wake-up indication information to the terminal needing to wake up in the terminal group on PDCCH monitor occasions configured for the terminal, or send, through the transceiver and 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 wake-up indication information instructs the terminal to wake up, and wherein the GTS indication information instructs the terminal needing to sleep to sleep.
