Abstract
A PDCCH blind detection method, a terminal and a network side device are provided. The method includes: detecting, by a terminal, an energy saving signal in an energy saving signal window; blindly detecting, by the terminal, the PDCCH within a target time if the energy saving signal is detected, a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range.

A Physical Downlink Control Channel (PDCCH) blind detection method, comprising:
- detecting, by a terminal, an energy saving signal in an energy saving signal window;
- blindly detecting, by the terminal, the PDCCH within a target time if the energy saving signal is detected, wherein a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range, the target time is an activation time of Discontinuous Reception (DRX);
- the energy saving signal window is located before the activation time, and the energy saving signal window includes one or more candidate positions;
- or
- the energy saving signal window includes candidate positions located before the activation time, and further includes candidate positions located within the activation time.
A PDCCH monitoring method, comprising:
- transmitting, by a network side device, an energy saving signal within an energy saving signal window, so that if the terminal has detected the energy saving signal, a PDCCH is blindly detected within a target time, wherein a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range, the target time is an activation time of DRX;
- wherein the energy saving signal window is located before the activation time, and the energy saving signal window includes one or more candidate positions;
- or
- the energy saving signal window includes candidate positions located before the activation time, and further includes candidate positions located within the activation time.
A terminal, comprising:
- a transceiver, a memory, a processor, and a program stored in the memory and executed by the processor, wherein:
- the processor is configured to detect an energy saving signal in an energy saving signal window;
- and
- if the energy saving signal is detected, the PDCCH is blindly detected within a target time, wherein a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range, the target time is an activation time of DRX;
- wherein the energy saving signal window is located before the activation time, and the energy saving signal window includes one or more candidate positions;
- or
- the energy saving signal window includes candidate positions located before the activation time, and further includes candidate positions located within the activation time.
