Problems solved by technology

like figure 1 As shown, the DRX modes of services 1 to 3 are configured for the UE, and the DRX cycles of services 1 to 3 are 10ms, 20ms and 256ms respectively, and the durations of the respective active states are 2ms, 4ms and 8ms respectively. The final joint DRX The active state time in the mode is as figure 1 As shown in the dotted box in , it can be seen that the UE needs to wake up and monitor frequently in each DRX cycle of each service, which leads to an increase in the time that the UE is in the active state and increases the power consumption of the UE.

example 1

[0073] Example 1: If Figure 4 As shown, the terminal is configured with only one main DRX pattern, that is, the first group of DRX patterns includes one DRX pattern, assuming that the DRX cycle of the DRX configuration 1 of the main DRX mode is 10ms, and the onDuration is 2ms. In addition, the terminal is also configured with 2 other DRX modes, namely DRX pattern 2 and DRX pattern 3, which correspond to DRX configuration 2 and DRX configuration 3 respectively. Their DRX cycles are 20ms and 256ms respectively, and the onDuration durations are 4ms and 256ms respectively. 8ms.

[0074] Figure 4 A schematic diagram of the network sending the monitoring indication message for other DRX modes in the main DRX mode is given in , where the arrow indicates that the monitoring indication message for the DRX mode indicated by the monitoring is sent during the onDuration of the main DRX mode. Figure 4 The dotted ellipse in indicates that the monitoring indication message for a certain...

example 2

[0077] Example 2: If Figure 5 As shown, the terminal is configured with 2 main DRX patterns, that is, the first group of DRX patterns includes 2 DRX patterns, corresponding to DRX configuration 1 and DRX configuration 2 respectively. Assume that the DRX cycle of DRX configuration 1 in the main DRX mode is 10 ms, and the onDuration is 2 ms; the DRX cycle of DRX configuration 2 is 18 ms, and the onDuration is 4 ms. In addition, the terminal is also configured with one other DRX mode 3, corresponding to DRX configuration 3, the DRX cycle is 256ms, and the onDuration is 8ms.

[0078] In this example 2, the network can indicate whether the terminal needs to wake up and monitor the corresponding PDCCH in the onDuration of other DRX patterns through any PDCCH or MAC CE of the main DRX, or indicate at the same time on the PDCCH or MAC CE of the two main DRXs, so as to Increase the transmission reliability of PDCCH or MAC CE. Figure 5 The dotted ellipse in indicates that the monito...

example 3

[0080] Example 3: The main DRX can also control itself to enter the sleep period

[0081] Such as Image 6 As shown, the terminal is configured with only one main DRX pattern, that is, the first group of DRX patterns includes one DRX pattern, assuming that the DRX cycle of the DRX configuration 1 of the main DRX mode is 10ms, and the onDuration is 2ms. In addition, the terminal is also configured with 1 other DRX mode, which is DRX pattern 2, corresponding to DRX configuration 2, its DRX cycle is 15ms, and the onDuration is 4ms.

[0082] In this Example 3, the network may indicate on the PDCCH or MAC CE in the primary DRX mode that the terminal does not need to monitor the primary DRX mode. After receiving the above instruction, the terminal controls the terminal to enter the sleep state, starts a pre-configured sleep timer, and stops monitoring in all DRX modes including the main DRX mode before the timer expires. After the timer expires, the terminal continues to monitor i...

Abstract

Embodiments of the present invention provide a method, a device, and a computer-readable storage medium for discontinuous monitoring. In the embodiment of the present invention, the terminal monitors the PDCCH or the MAC CE of the first group of DRX modes at the time of the active state of the first group of DRX modes, while for the second group of DRX modes, the terminal only needs to monitor the first group of DRX modes according to the time of the first group of DRX modes. The monitoring instruction message received by the PDCCH or MAC CE, the monitoring is performed on the second group of DRX modes at the required time, so that it is not necessary to continuously monitor the second group of DRX modes, thereby reducing the monitoring on the second group of DRX modes. time, reduce the wake-up time of the terminal, and reduce the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a discontinuous monitoring method, device and computer-readable storage medium. Background technique [0002] The Long Term Evolution (LTE) system uses Discontinuous Reception (DRX) technology to reduce terminal power consumption. The DRX mechanism allows the terminal (UE) to enter the sleep state periodically without monitoring the physical downlink control channel (PDCCH) subframe, and only wakes up from sleep when it needs to be monitored, thereby achieving the purpose of power saving. Different from LTE, UE needs to support multiple services in the New Radio Interface (NR) network, and each service has its own service transmission mode and quality of service (QoS) requirements, such as requiring different delays and rates. For example, assume that service 1 is a vehicle-to-pedestrian (V2P) service with ultra-low latency requirements; service 2 is VoIP (V...
