Abstract

The embodiments of the present disclosure provide a signal receiving method, a signal sending method, a terminal, and a network side device. The receiving method includes: receiving, by a terminal, indication information and data scheduling information sent by a network side device; entering, by the terminal, an energy saving mode or an abnormal power consumption mode according to the indication information, wherein power consumption in the abnormal power consumption mode is lower than power consumption in the normal power consumption mode; performing, by the terminal, data transmission according to the data scheduling information when a data transmission time corresponding to the data scheduling information arrives.

First claim

What is claimed is:

1. A signal receiving method, comprising:
receiving, by a terminal, indication information and data scheduling information sent by a network side device;
entering, by the terminal, an energy saving mode or an abnormal power consumption mode according to the indication information, wherein power consumption in the abnormal power consumption mode is lower than power consumption in the normal power consumption mode;
performing, by the terminal, data transmission according to the data scheduling information when a data transmission time corresponding to the data scheduling information arrives;
wherein the indication information is carried on Physical downlink control channel (PDCCH);
wherein the indication information and the data scheduling information are carried on the same Downlink Control Information (DCI); or
the indication information and the data scheduling information are sent on different DCIs in a same time unit; or
the indication information and the data scheduling information are sent in different time units, and a time domain position of a time unit in which the PDCCH carrying the indication information is located is earlier than a time domain location of a time unit in which the PDCCH of the data scheduling information is located,
wherein if the network side device needs to transmit a reference signal to the terminal after sending the data scheduling information and before the data transmission, the indication information is used to indicate that the terminal does not enter the energy saving mode or enters the normal power consumption mode, and the method further includes:
receiving, by the terminal, the reference signal;
and/or,
if the network side device does not need to transmit the reference signal to the terminal after sending the data scheduling information and before the data transmission, the indication information is used to indicate that the terminal enters the energy saving mode, or does not enter the normal power consumption mode.

2. The method according to claim 1 , wherein the indication information includes at least one of the following:
a processing capability threshold, time scheduling information indication, energy saving indication, time scheduling information, time domain interval indication;
wherein the time scheduling information indication is used to indicate whether the time scheduling information corresponding to the data scheduling information is the same as a previous time scheduling information;
the energy saving indication is used to indicate whether to enter the energy saving mode, or to indicate whether to enter the normal power consumption mode;
the time domain interval indication is used to indicate a time domain interval between data transmission and the data scheduling information.

3. The method according to claim 2 , wherein if the time scheduling information indicates that the time scheduling information corresponding to the data scheduling information is the same as the previous time scheduling information, it is determined whether to enter the energy saving mode or whether to enter the abnormal power consumption mode according to the previous time scheduling information; or
if the energy saving indication indicate to enter the energy saving mode, or not to enter the normal power consumption mode, the terminal enters the energy saving mode or enters the abnormal power consumption mode; or
the terminal enters the energy saving mode or enter the abnormal power consumption mode according to the time scheduling information; or
the terminal enters the energy saving mode or enter the abnormal power consumption mode according to the time domain interval.

4. The method according to claim 3 , wherein if the time scheduling information indicates that the time scheduling information corresponding to the data scheduling information is different from the previous time scheduling information, terminal does not to enter the energy saving mode, or enters the normal power consumption, or it is determined whether to enter the energy saving mode or whether to enter the abnormal power consumption mode according to the time scheduling information corresponding to the data scheduling information; or
if the energy saving indication indicates not to enter the energy saving mode or to enter the normal power consumption mode, then the terminal does not enter the energy saving mode or enters the normal power consumption mode; or
if the processing capability of the terminal indicates that processing time of the terminal is higher than the time domain interval, the terminal does not enter the power saving mode, or enters the normal power consumption mode.
