Embodiment Construction

[0124] The embodiment of the present invention is applied to a terminal in a sleep state.

[0125] After the terminal enters the sleep state, it monitors the wake-up signal sent by the network side device; the terminal switches from the sleep state to the wake-up state after listening to the wake-up signal.

[0126] Such as figure 1 As shown, starting from t0, the terminal enters the sleep state; when downlink data arrives, the network side device will send a wake-up signal to the terminal; for example, the terminal monitors the wake-up signal at t1. The terminal is woken up at t2 and enters the wake-up state; when the terminal is in the wake-up state, it processes the received downlink data; and enters the sleep state again at t3.

[0127] In the embodiment of the present invention, after the terminal enters the sleep state, it monitors the wake-up signal sent by the network side device; wherein, the terminal switches from the sleep state to the wake-up state after listening...

Abstract

The present invention relates to the technical field of wireless communication, and in particular to a method for performing communication in a sleep state of a terminal and a terminal, which are used to solve the problem that the terminal will lose synchronization with network side equipment after entering the sleep mode. In the embodiment of the present invention, after the terminal enters the sleep state, it monitors the wake-up signal sent by the network side device; during the process of monitoring the wake-up signal, it performs at least one downlink operation; wherein, the downlink operation is used to make the The terminal maintains synchronization and / or online status with the network side device. The embodiment of the present invention prevents the terminal from being in a sleep state for a long time, resulting in out-of-synchronization or loss of basic connection with the network-side device, thereby further improving system performance.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for performing communication in a sleep state of a terminal and a terminal. Background technique [0002] In the newly designed 5G NR (New RAT / Radio, new wireless access) system in the future, the system supports larger bandwidth and more complex services. ITU (International Telecommunication Union, International Telecommunication Union) puts forward clear requirements for 5G NR systems on the energy-saving indicators of terminals. The terminal needs to reduce power consumption as much as possible, whether it is in data transmission or in standby state. [0003] In the 5G NR system, the current working state of the terminal is divided into three types: RRC (Radio Resource Control, unlimited resource control)_IDLE (idle) state, RRC_Inactive (inactive) state and RRC_Connected (connected) state, in the first two states The downlink terminal needs to ...
