example 1

[0157] Step 1. The network side device notifies the terminal to enter the energy-saving mode and start monitoring the energy-saving signal through network signaling; the network signaling can be high-layer RRC signaling, or bottom-layer MAC CE or PDCCH commands.

[0158] Preferably, the network side device sends the network signaling to the terminal when there is no downlink data transmission;

[0159] Alternatively, the network side device sends the network signaling to the terminal after receiving the request signaling that the terminal requests to enter the energy-saving mode;

[0160] Or, after the network-side device determines that the terminal enters the energy-saving mode, it sends the network signaling to the terminal;

[0161] Or, when the terminal does not have delay-sensitive services, the network side device sends the network signaling to the terminal after determining that the terminal enters the energy-saving mode.

[0162] Step 2: After receiving the network s...

example 2

[0169] Step 3: The terminal and the network side configure the energy-saving timer according to the energy-saving timer configured on the network side or according to the energy-saving timer specified in the protocol, start the energy-saving timer, and restart the timer when there is data transmission.

[0170] Step 4, when the energy-saving timer expires, the terminal starts to monitor the energy-saving signal according to the configuration parameters of the energy-saving signal. After the energy-saving timer expires, the network-side device wakes up the terminal by sending an energy-saving signal to notify the terminal to receive data, instead of directly sending the PDCCH.

[0171] As a preferred embodiment, step 21 includes:

[0172] Determine the configuration parameters of the energy-saving signal according to the network side configuration and / or agreement;

[0173] The terminal enters the energy-saving mode and periodically monitors or continuously monitors the energy...

[0181] Step 5, the terminal periodically monitors the energy-saving signal (the network or protocol configures the terminal to periodically monitor the energy-saving signal), and when the terminal detects its own energy-saving signal for wake-up, it wakes up and continues to monitor whether there is PDCCH scheduling, otherwise the terminal will continue to save energy. mode, monitor the energy-saving signal at the sending time of the next energy-saving signal.

[0182] Step 6: When the network has data to send to the terminal, it first sends an energy-saving signal to wake up the terminal according to the cycle of sending the energy-saving signal, notifying the terminal that it needs to wake up to receive data, and then sends a PDCCH signal to schedule data transmission. Otherwise, the network does not send an energy-saving signal to wake up the terminal when the energy-saving signal is sent, but sends a sleep energy-saving signal to notify the terminal to continue to enter the...

Abstract

The invention provides a channel monitoring and energy-saving signal processing method and a device, a terminal and network side equipment. The monitoring method comprises the steps that the terminalenters an energy-saving mode to monitor an energy-saving signal; and in the energy-saving mode, the terminal determines whether a downlink control channel needs to be monitored according to whether the energy-saving signal is monitored. In the method of the invention, the terminal in the connected state does not continuously monitor the downlink control channel any more; the energy-saving signal is monitored in the energy-saving mode instead of the downlink controllable channel, whether the downlink control channel needs to be monitored is determined according to whether the energy-saving signal is monitored, the demodulation complexity of the energy-saving signal is lower than that of the downlink control channel, and / or the frequency or time for monitoring the energy-saving signal is less than that for monitoring the downlink controllable channel, thereby reducing the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel monitoring, energy-saving signal processing, device, terminal and network side equipment. Background technique [0002] The terminal UE in the current connected state needs to monitor the PDCCH (Physical Downlink Control Channel) and analyze it to determine whether there is downlink data transmission. When there is no data transmission, the terminal monitors and analyzes the PDCCH, which will cause invalid power overhead. In order to reduce the power consumption overhead of the terminal, currently, the network side is supported to configure DRX (Discontinuous Reception, discontinuous reception) for the terminal. [0003] In the fourth-generation and fifth-generation mobile communication systems (4G, 5G or NR (new radio, new air interface) system), DRX is introduced. This method allows the terminal to enter the sleep state periodically at certain times wi...
