As an optional embodiment, the at least one DRX cycle start offset and/or the activation order of the at least one DRX cycle start offset corresponds to a dynamic DRX parameter adjustment technique; the configuration effect is as follows: for example, there is a regularity in the non-positive integer period of XR traffic, so the network may configure the order of application of multiple DRX cycle start offsets to match the arrival of XR frames.

In the embodiment of the application, at least one item of RRC configuration information of the energy-saving related technology is interacted through an Xn interface, so that energy-saving configuration information synchronization or alignment among nodes of a base station or a cell group is realized, and further, energy saving of a terminal is realized.

The network configures multiple DRX cycle starting positions, which may also be referred to as DRX duration starting positions, through RRC signaling to implement dynamic or semi-static DRX starting offset adjustment to align non-positive integer frame periods of XR traffic.

As shown in fig. 3, before the energy saving configuration information is not exchanged between the MCG and the SCG, the MCG and the SCG may be respectively configured with different DRX starting positions, and such misaligned DRX starting positions may cause an increase in duration of PDCCH monitoring performed by the terminal, thereby affecting energy saving of the terminal. As shown in fig. 4, in the first example, the MCG interacts with the SCG (or the target cell interacts with the source cell during cell handover) for at least one DRX cycle start offset, so as to reduce the PDCCH monitoring duration of the terminal and achieve energy saving for the terminal. The purpose of the energy saving configuration information interaction is to avoid the DRX monitoring of the MCG and the SCG as shown in fig. 3 as much as possible, so as to reduce the power consumption of the terminal. Furthermore, the network may also interact with the active order configuration of at least one DRX start position.

As another optional embodiment, the configuration information of at least one DRX configuration and/or the activation sequence of the at least one DRX configuration may correspond to the multiple DRX configuration technologies;

optionally, the configuration information of a set of DRX configurations includes at least one of the following information:

In at least one embodiment of the present application, configuration information of at least one set of temporal patterns may be used for semi-static alignment and overlay; for example, frames of non-positive integer periods of XR traffic arrive, thereby reducing unnecessary power consumption due to mismatches;

optionally, the configuration information of the set of time domain patterns includes at least one of:

alternatively, the start time of the time domain pattern may be related to the start time of the traffic data.

Alternatively, the start time of the time domain pattern may be related to the start time of the first service data unit. The service data unit may be a service packet, an application data unit or a data frame.

the association relationship information of the time domain pattern and the service information comprises: at least one of a service type, a service flow and a quality of service (QoS) flow;

optionally, each time-domain pattern may correspond to one or more traffic types or traffic flows or QoS flows.

DRX-related information included in the time domain pattern.

Optionally, the DRX-related information of the DRX cycle included in the time domain pattern includes at least one of:

the number of DRX cycles;

optionally, the time domain pattern includes one or more DRX cycles.

DRX inactivity timer (DRX inactivity timer) information of the DRX cycle. Optionally, the DRX inactivity timer information of the DRX cycle refers to DRX inactivity timer length information.

Example two, the energy-saving configuration information of the interaction 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 periodic circulation according to the time domain patterns. For example, the network configuration may consist of multiple non-consecutive time windows in each time-domain pattern. As shown in fig. 5, the network configures a time domain pattern including 3 time windows, each time window has a length of 8ms, and the interval between the start positions of each time window has a length of 16965 ms,17ms, and 17ms, respectively.

For another example, the network configuration time domain pattern is composed of a plurality of DRX cycles, and the relevant configuration parameters of each DRX cycle may be the same or different, as shown in fig. 6, the network configuration time domain pattern is composed of 3 DRX cycles, all parameters of the latter two DRX cycles are the same, and the DRX cycles 2 and 3 are both 17ms in length, but are different from the first DRX cycle in length, and the first DRX cycle is 16ms in length. The DRX durations for all three periods are 8ms.

The purpose of the above time domain pattern configuration is to match the non-positive integer periodic frame arrival of XR traffic for semi-static. The network configuration or protocol stipulates that the terminal adopts corresponding PDCCH monitoring behavior in a time window in a time domain pattern, carries out scheduling monitoring on XR frames (XR frames), and the like. The interaction of the configuration information of the time domain patterns can enable the MCG to know the configuration condition of the SCG for the time domain patterns, and can also facilitate the MCG to trigger and align the SCG for the time domain patterns, so that the characteristic of better matching XR service non-positive integer period is realized, the communication performance is improved, the data scheduling delay is reduced, and the like. In addition, the MCG and the SCG align the configuration of the time window length through information interaction, which can further reduce the misalignment of the PDCCH monitoring duration time caused by the MCG and the SCG, that is, the PDCCH monitoring of the MCG and the SCG can be overlapped as much as possible in the time domain, thereby reducing the power consumption and realizing the energy saving of the terminal.

In at least one embodiment of the present application, the energy saving indication configuration information includes at least one of:

the energy-saving radio network temporary identifier PS-RNTI is used for scrambling the cyclic redundancy check CRC of the DCI formats 2-6;

a power saving offset used for determining a detection start time of the DCI formats 2-6;

size information of DCI formats 2-6;

location information of energy-efficient indications in DCI formats 2-6; the location information of the energy-saving indication in DCI formats 2-6 is for one terminal, and may also be referred to as: the energy saving corresponding to the terminal indicates the position information in DCI formats 2-6;

energy-saving wake-up information, wherein the energy-saving wake-up information is used for waking up a terminal under the condition that the terminal does not detect DCI formats 2-6;

first energy-saving indication information, wherein the first energy-saving indication information is used for indicating a terminal to transmit a periodic first Reference Signal Received Power (RSRP) report under the condition that a DRX duration timer is not started;

second energy saving indication information for indicating the terminal to transmit periodic CSI reports other than the periodic layer one RSRP report without turning on the DRX duration timer.

The DCI formats 2-6 scrambled by the energy-saving RNTI can be abbreviated as DCP.

Example three, the interactive energy saving configuration information comprises: 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 with reference to the energy saving indication configuration information of the MCG. The maximum value of PS-offset (power saving offset) may be 15ms, that is, the network may configure the monitoring time of the DCP within 15ms before the starting position of the DRX cycle.

For example, as shown in fig. 7 and fig. 8, the DCP configuration of the network configuration MCG, and the relevant parameters of the search space group and the associated CORESET corresponding to the DCP (DCI 2-6) of the MCG include: monitoring time, monitoring period, monitoring duration and the like. The network configures the DCP configuration of the SCG, and related parameters of the search space group corresponding to the DCP (DCI 2-6) of the MCG and the associated CORESET.

In fig. 7, the MCG and the SCG do not perform information interaction of the DCP, and in fig. 8, the MCG and the SCG perform DCP information interaction alignment, so that energy saving of the terminal is achieved.

In at least one embodiment of the present application, the configuration information of the wake-up channel or wake-up signal includes at least one of:

monitoring time information of the wake-up channel or the wake-up signal;

monitoring period information of a wake-up channel or a wake-up signal;

duration information of a listening occasion of a wake-up channel or wake-up signal;

time-frequency domain resource information of a wake-up channel or wake-up signal; for example, the time-frequency domain pattern of the wake-up signal;

monitoring time window information of a wake-up channel or a wake-up signal; the terminal monitors a wakeup indication at the monitoring time of the wakeup channel or the wakeup signal in the monitoring time window;

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

Mapping relation information of the awakening indication and the awakening indication bit; note that the wake-up indication refers to specific indication content of the wake-up indication. For example, the network may configure 2 bits for the wake-up indication, and then the mapping relationship between the specific indication content of the wake-up indication and the two bits needs to be configured.

Frequency hopping format information of the wake-up signal;

the sequence information of the wake-up signal comprises a sequence index, a sequence generation mode and the like;

the association relation information of the wake-up channel or wake-up signal and the search space group;

optionally, the association relationship between the wake-up signal or the wake-up signal and the search space group refers to: and when the terminal receives different wake-up signals, the terminal switches to the search space group associated with the terminal to monitor the target content. And the incidence relation between the wake-up signal and the search space group is configured by network side equipment or agreed by a protocol. For example, wake-up signal 1 is associated with search space group 1; the wake-up signal 2 is associated with the search space group 2. And under the condition that the terminal receives the wake-up signal 2, the terminal switches to the search space group 2 to monitor the target content.

RNTI information used for scrambling first DCI, wherein the first DCI carries the awakening indication;

size information of the first DCI;

the wake-up indicates starting location information in the first DCI.

Optionally, the configuration information of the wake-up channel or the wake-up signal further includes: the wake-up associated with a terminal indicates starting location information in the first DCI.

As an optional embodiment, the listening time window information of the wake-up channel or the wake-up signal comprises at least one of:

the duration of the listening time window, i.e. the duration of the listening time window or the time window length;

monitoring the starting position of a time window;

monitoring the offset of the starting position of the time window relative to the starting position of the DRX period;

monitoring the end position of the time window;

monitoring the offset of the end position of the time window relative to the starting position of the DRX period;

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

Example four, the interactive energy saving configuration information is configuration information of a wake-up signal, which may be referred to as WUS;

XR is periodic traffic, but the time of arrival of each XR frame at the network is jittery relative to the ideal periodic arrival time. Therefore, in order to cope with the jitter of the XR data packet, the network configures the WUS listening opportunity (MO) to achieve the balance between reducing the scheduling delay and saving the power of the terminal as much as possible. As shown in fig. 9 and 10, the network configures WUS snooping related configurations of MCG and SCG, respectively, including a snooping time window of wakeup indication, a snooping period of WUS MO, WUS, and so on. In addition, in this example, the start and end positions of the listening time window of the wake-up indication are configured relative to the start and end positions of the DRX operation.

Because the XR jitter range is very large, the range of the monitoring time window of the WUS MO configured for the network side is also relatively large, and if the MCG and the SCG are configured independently without information interaction, as shown in fig. 9, the monitoring time windows of the MCG and the SCG are staggered in time domain, which results in very long monitoring time of the terminal and excessive power consumption.

In this example, the effect shown in fig. 10 can be achieved by interacting the configuration information related to the wake-up indication between the MCG and the SCG, that is, the configuration related to the wake-up indication between the MCG and the SCG can be aligned, so that the monitoring duration of the terminal is reduced, and power consumption can be saved.

In at least one optional embodiment of the present application, the PDCCH monitoring indication configuration information includes at least one of:

skipping the duration information monitored by the PDCCH;

optionally, the duration of skipping the PDCCH monitoring may be N milliseconds, N time slots, N subframes, or a time interval from the end of the time unit receiving the PDCCH monitoring indication to the start of the next DRX cycle, which is not limited herein.

Mapping relation information between the duration of the skipping PDCCH monitoring and the skipping PDCCH monitoring indication bit; for example, the skip PDCCH monitoring indication bit is 2 bits, and the mapping relationship is: the duration 1 for skipping PDCCH monitoring corresponds to an indication bit "00"; the duration 2 for skipping PDCCH monitoring corresponds to an indication bit "01"; the duration 3 for skipping PDCCH monitoring corresponds to an indication bit of "10"; the duration 4 for skipping PDCCH monitoring corresponds to an indication bit "11";
