Problems solved by technology

[0004] However, in the above-mentioned prior art, after the user equipment is in the active state and receives the data packets, it will still maintain the wake-up state for a period of time, and the energy consumption in the wake-up state is the same as that in the active state. There will be a long time after the data will not send the next piece of data, which will make the user device wake up for more time, increase energy consumption and reduce battery life

Embodiment Construction

[0114] Below, refer to the appendix Figure 1 to Figure 7 As shown, a method for discontinuous reception of wireless communication includes:

[0115] Step 1, seven state settings; the seven states are: active state, long wake-up state, normal wake-up state, short sleep state, short sleep monitoring state, long sleep state and long sleep monitoring state;

[0116] As an example, the active state is represented by S0101, and S0101 is that the user equipment continuously receives and decodes data, and the battery consumption is the highest;

[0117] As an example, the long wakeup state is represented by S1102. Although S1102 does not receive data, it monitors the PDCCH, and the power consumption is still the same as the active state; the long wakeup state is inactive, and the timer of the long wakeup state starts timing. ;

[0118] As an example, the ordinary wake-up state is represented by S2103; in S2103, although no data reception is performed, but the PDCCH is monitored, th...

Abstract

The present invention is a method for discontinuous reception of wireless communication, comprising: seven state settings; the seven states are: active state, long wake-up state, normal wake-up state, short sleep state, short sleep monitoring state, long sleep state state and long sleep monitoring state; the data packet will also carry two flags, flag1 and flag2 when carrying data; the content of the two flags is related to the time interval when the next data packet arrives, and the invention lies in that the base station can know the following After how many time slot intervals a data packet will be sent, the base station can design corresponding signs according to the length of the interval. If the interval is short, the flag flag1 is set to 1, so that the user equipment enters a long wake-up state to receive data packets in a short time; if the interval is long, the flag flag2 is set to 1, which makes the user equipment enter a long sleep state and reduce energy consumption. Compared with the prior art, the seven-state scheme with the DRX function of the present invention has a wider application range, and can reduce the overall energy consumption of the user equipment to a greater extent.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for discontinuous reception of wireless communication, which solves the problem of extra energy consumption caused by user equipment in the process of receiving data packets. Background technique [0002] Discontinuous Reception (DRX) is a data receiving mechanism in which IoT devices are in a Radio Resource Control (RRC) connection state. It can dynamically switch part of the circuit of the device from an active state to a short sleep state or a long sleep state according to the environment, thereby greatly saving energy. [0003] In the prior art, there is a four-state DRX user equipment; the user equipment has four states, namely: active state, wake-up state, short-sleep state, and long-sleep state. In the active state, the user equipment continuously receives data packets from the base station. When no data arrives, the user equipment enters t...
