XR includes augmented reality (AugmentedReality, AR), virtual reality (Virtual Reality, VR) and cloud gaming (Cloud gaming), etc. The XR service has the characteristic of a fixed frame rate, that is, the service data of the XR service reaches the UE in a fixed period, but there will be additional delay jitter based on this fixed period.

In order to reduce the power consumption of user equipment (UE) during communication, the key feature of connected discontinuous reception (ConnectedDiscontinuous Reception, C-DRX) is introduced in 3GPP new radio (NR). In C DRX mode, the UE does not need to continuously monitor the physical downlink control channel (PDCCH). Instead, it starts PDCCH monitoring when it reaches the beginning of the working period (on duration). If the monitoring ends or the working period ends, it will enter the sleep period. (off duration), there is no need to monitor PDCCH during the sleep period to achieve energy saving.

In C DRX mode, the problem of increased data transmission delay caused by delay jitter in XR services needs to be solved.

At this time, the working period has not yet started, and the UE 101 is still in a dormant state. The network device 102 can only wait until the working period starts before scheduling, resulting in an increase in data transmission delay.

An embodiment of the present disclosure provides a method for transmitting instruction information. Refer to Figure 2. Figure 2 illustrates a method for transmitting instruction information according to an exemplary embodiment. As shown in Figure 2, the method includes steps S201 to S203. specific:

Step S201, the network device 102 sends first indication information to the user equipment 101. The first indication information is used to enable the user equipment 101 to determine whether to enable physical downlink control channel PDCCH monitoring in advance before the working period in the connected discontinuous reception C-DRX. .

Step S202: After receiving the first indication information sent by the network device 102, the user equipment 101 determines whether to enable physical downlink control channel PDCCH monitoring before the working period in the connected discontinuous reception C-DRX according to the first indication information.

In some possible implementations, the first indication information is used to indicate whether to enable physical downlink control channel PDCCH monitoring in advance before the working period in connected discontinuous reception C-DRX. When the first indication information indicates yes, the user equipment 101 determines to enable PDCCH monitoring before the working period in C-DRX. When the first indication information indicates no, the user equipment 101 determines to enable PDCCH monitoring before the working period in C-DRX. Turn on PDCCH monitoring at the beginning.

In some possible implementations, the first indication information may be called early start indication information.

In some possible implementations, the methods of the embodiments of the present disclosure can be applied to XR business scenarios.

In an example, as shown in Figure 3, during the data transmission process of the XR service, the frame rate of sending data frames is F frames per second (FPS). In each cycle (1/F) of sending a data frame, for example, from sending the data packet k corresponding to the video data frame K to sending the data packet (k+1) corresponding to the video data frame (K+1) During the cycle, the delay jitter is within the set range. It can be understood that in the example corresponding to Figure 3, the delay jitter and the packet size of the service data follow probability distribution (probability distribution) respectively.

In an example, the frame rate F is 60FPS, the period is 16.67ms, and the delay jitter is in the range of [4, -4]ms.

In some possible implementations, corresponding to periodic XR service data, periodic C-DRX can be configured in a matching manner.

In some possible implementations, C-DRX includes an on duration and a sleep period (off duration).

In an example, during the working period, the user equipment 101 monitors the PDCCH and receives downlink XR service data.

In an example, the user equipment 101 does not monitor the PDCCH during the sleep period. Normally, the user equipment 101 can turn off radio frequency structures such as receivers during the sleep period to reduce power consumption and achieve energy saving. In some cases (such as when SPS PDSCH transmission is activated), the user equipment 101 will also monitor some downlink channels during the sleep period.

In some possible implementations, the network device 102 sends the first indication information before the working period of C-DRX.

In an example, for periodic C-DRX, each C-DRX also includes a periodic working period. Before each working period in C-DRX, the first instruction information corresponding to the working period in C-DRX can be sent, thereby accurately determining the processing method of each working period in C-DRX.

In this disclosed embodiment, the network device 102 sends the first indication information, and the user equipment 101 can determine whether PDCCH monitoring needs to be enabled in advance before the working period in C-DRX according to the indication of the advance indication information. Therefore, the user equipment 101 can combine the instruction information to enable PDCCH monitoring in advance between the C-DRX working periods to receive data that arrives in advance due to delay jitter, avoiding the need to wait until the C-DRX working period is started after the service data is generated. Only in this way can the data transmission delay problem caused by scheduling resources be eliminated, thereby effectively reducing the data transmission delay.
