Example 2, the interactive energy saving configuration information is the configuration information of the time domain pattern

The network side configures at least one set of time-domain patterns for the terminal, and the terminal performs a periodic cycle according to the time-domain pattern. For example, the network configuration consists of multiple non-consecutive time windows in each time domain pattern. As shown in FIG. 5 , the network configuration includes 3 time windows in a time domain pattern, the length of each time window is 8 ms, and the interval lengths between the starting positions of each time window are 16 ms, 17 ms, and 17 ms respectively.

For another example, the network configuration time domain pattern consists of multiple DRX cycles, and the related configuration parameters of each DRX cycle can be the same or different. All the parameters of the cycle are the same, the length of DRX cycle 2 and DRX cycle 3 are both 17ms, but the length of the first DRX cycle is different, the length of the first DRX cycle is 16ms. The DRX onduration length of these three cycles is 8ms.

The purpose of the above time-domain pattern configuration is to semi-statically match the frame arrival of the non-positive integer period of the XR service. The network configuration or protocol stipulates that the terminal adopts the corresponding PDCCH monitoring behavior in the time window in the time domain pattern, and performs scheduling and monitoring on the XR frame (XR frame). The interaction of the configuration information of the above-mentioned time-domain patterns can enable the MCG to understand the configuration of the SCG for the time-domain patterns, and can also facilitate the alignment of the MCG trigger and the SCG for the time-domain patterns, so as to better match the non-positive integer period of the XR service Features, improve communication performance, reduce data scheduling delay, etc. In addition, the MCG and SCG align the configuration of the time window length through information interaction, which can further reduce the misalignment of the PDCCH monitoring duration between the MCG and the SCG, that is, allow the PDCCH monitoring of the MCG and SCG to overlap as much as possible in the time domain, so that This reduces power consumption and realizes terminal energy saving.

Wherein, DCI formats 2-6 of energy-saving RNTI scrambling may be referred to as DCP for short.

Example 3, the interactive energy saving configuration information includes: energy saving indication configuration information

For example, the MCG sends the energy saving indication configuration information to the SCG, and the SCG may perform its own energy saving related configuration by referring to the energy saving indication configuration information of the MCG. Wherein, the maximum value of PS-offset (energy-saving offset) can be 15ms, that is, the network can configure the monitoring timing of DCP within the range of 15ms before the starting position of the DRX cycle.

For example, as shown in Figure 7 and Figure 8, the network configures the DCP configuration of the MCG, and the search space group corresponding to the DCP (DCI2-6) of the MCG and related parameters of the associated CORESET, including: monitoring timing, monitoring period, and monitoring duration wait. The network further configures the DCP configuration of the SCG, and the search space group corresponding to the DCP (DCI2-6) of the MCG and related parameters of the associated CORESET.

The information of the wake-up indication carried by the wake-up channel or the wake-up signal; for example, index, bit string (bitstring) or bitmap (bitmap); for example, the wake-up indication carried by the wake-up channel or the wake-up signal is used to indicate skipping the wake-up channel, wake-up Signal, the monitoring duration of at least one item in the PDCCH. For example, the specific content of the wake-up indication may include: an index value corresponding to a duration indicating skipping PDCCH monitoring, or an index value corresponding to a duration indicating skipping wake-up channel or wake-up signal monitoring.

The mapping relationship information between the wake-up indication and the wake-up indication bits; it should be noted that the wake-up indication refers to specific indication content of the wake-up indication.

When the terminal receives the wake-up signal 2, the terminal switches to the search space group 2 to monitor the target content.

The end position of the monitoring time window;

The offset of the end position of the listening time window relative to the start position of the DRX cycle;

The period of the listening time window, for example, matches the DRX period, or matches the service period.

Example 4, the interactive energy-saving configuration information is the configuration information of the wake-up signal, and the wake-up signal may be called WUS;

XR is a periodic service, but the arrival time of each XR frame on the network fluctuates back and forth relative to the arrival time of the ideal cycle. Therefore, in order to cope with the jitter of the XR data packet, the network configures the WUS monitoring opportunity (MO) to achieve a balance between reducing the scheduling delay and energy saving of the terminal as much as possible. As shown in Figure 9 and Figure 10, the network configures the WUS monitoring related configurations of MCG and SCG respectively, including the monitoring time window of the wake-up indication, WUS MO, WUS monitoring period, etc. In addition, in this example, the start and end positions of the monitoring time window of the wake-up indication are configured relative to the start and end positions of the DRX onduration.

Since the jitter range of XR is very large, the monitoring time window range of WUS MO configured for the network side will also be relatively large. If MCG and SCG are configured independently without information interaction, the situation shown in Figure 9 will result. The monitoring time windows of the MCG and SCG are staggered in the time domain, resulting in a very long monitoring time of the terminal and excessive power consumption.

In this example, the configuration information of the wake-up indication exchanged between the MCG and the SCG can achieve the effect shown in Figure 10, that is, the configurations related to the wake-up indication of the MCG and SCG can be aligned, and the monitoring duration of the terminal is reduced, which can save power consumption.
