Wireless communication discontinuous reception method

Abstract

The invention relates to a discontinuous reception method for wireless communication. The method comprises the following step of setting seven states, wherein the seven states are respectively an active state, a long wake-up state, a common wake-up state, a short sleep state, a short sleep monitoring state, a long sleep state and a long sleep monitoring state. The data packet carries data and also carries two marks, namely a flag1 and a flag2 at the same time; the content of the two marks is related to the arrival time interval of the next data packet, and the base station can know how many time slots the next data packet is to be sent after, so that the base station can design the corresponding marks according to the length of the interval. If the interval is short, the flag 1 is set as 1, and the user equipment is enabled to enter a long wake-up state so as to accept the data packet in a short time; and if the interval is long, the flag 2 is set as 1, so that the user equipment enters a long sleep state, and the energy consumption is reduced. Compared with the prior art, the application range of the seven-state scheme with the DRX function is wider, and the total energy consumption of the user equipment can be reduced to a greater extent.

Description

technical field [0001] The 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 (Discontinuous Reception, DRX) is a data receiving mechanism in which an IoT device is in a radio resource control (Radio Resource Control, RRC) connection state. It can dynamically switch some circuits 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 ...

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
