[0081] As another optional embodiment, the first communication device is the primary cell group, the secondary cell group, the target cell during the handover process, or the source cell during the handover process, and the second communication device is a terminal;

[0082] Alternatively, the first communication device can be a first terminal, and the second communication device can be a second terminal. For example, the first and second communication devices can exchange energy-saving configuration information through a direct communication sidelink interface (also known as a PC5 interface).

[0083] In at least one embodiment of this application, the energy-saving configuration information includes at least one of the following:

[0084] At least one discontinuous reception DRX cycle start offset;

[0085] It should be noted that the DRX cycle start offset can also be called the start position of the DRX cycle, the start offset of the DRX duration, or the start position of the DRX duration.

[0086] The activation order of at least one DRX cycle start offset;

[0087] It should be noted that the activation order can also be called the application order; for example, the activation order could be: DRX cycle start offset 1, DRX cycle start offset 2, DRX cycle start offset 3, DRX cycle start offset 4. Optionally, each activated DRX cycle start offset has a corresponding activation duration configuration. For example, the activation order could be: DRX cycle start offset 1, activation time is 5 DRX cycles; DRX cycle start offset 2, activation time is 5 DRX cycles; DRX cycle start offset 3, activation time is 5 DRX cycles; DRX cycle start offset 4, activation time is 5 DRX cycles.

[0088] Configuration information for at least one DRX configuration;

[0089] The activation order of the at least one DRX configuration;

[0090] It should be noted that the activation order can also be called the application order; for example, the activation order could be: DRX configuration 1, DRX configuration 2, DRX configuration 3, DRX configuration 4. Optionally, each activated DRX configuration can be configured with a corresponding activation duration. For example, the activation order could be: DRX configuration 1, activation time of 5 DRX cycles; DRX configuration 2, activation time of 5 DRX cycles; DRX configuration 3, activation time of 5 DRX cycles; DRX configuration 4, activation time of 5 DRX cycles.

[0091] At least one set of time-domain pattern configuration information, wherein the time-domain pattern includes at least one time window; optionally, the terminal listens for target content within the at least one time window based on the time-domain pattern configuration information. The target content includes at least one of the following: Physical Downlink Control Channel (PDCCH); Physical Downlink Shared Channel (PDSCH); Physical Uplink Shared Channel (PUSCH); and a wake-up signal.

[0092] Energy saving indicator configuration information;

[0093] Configuration information for the wake-up channel or wake-up signal;

[0094] Optionally, the configuration of the wake-up channel or wake-up signal is related to the time-domain pattern or DRX configuration. For example, the wake-up channel or wake-up signal is configured within at least one time window of the time-domain pattern, or the wake-up channel or wake-up signal is configured within the duration of the DRX cycle.

[0095] Physical Downlink Control Channel (PDCCH) monitoring indication configuration information;

[0096] Energy-saving configuration information alignment indicator.

[0097] As an optional embodiment, at least one DRX cycle start offset and / or the activation order of at least one DRX cycle start offset correspond to dynamic DRX parameter adjustment technology; the configuration effect is: for example, the non-positive integer cycle of XR service has a certain pattern, so the network may configure the application order of multiple DRX cycle start offsets to match the arrival of XR frames.

[0098] This application embodiment uses the Xn interface to exchange RRC configuration information of at least one of the following energy-saving related technologies, thereby achieving synchronization or alignment of energy-saving configuration information between base station or cell group nodes, and thus realizing terminal energy saving. The at least one energy-saving related technology includes:

[0099] Dynamic DRX parameter adjustment, including dynamically adjusting the DRX start position to match the arrival of non-periodic Extended Reality XR service packets;

[0100] Multiple DRX configurations, dynamically switchable to adapt to business characteristics;

[0101] Skip PDCCH instructions;

[0102] Search space group switching: Dynamically switch search space groups to adapt to business characteristics;

[0103] Wake-up channel or wake-up signal configuration, replacing PDCCH listening by detecting the wake-up channel or wake-up signal.

[0104] Example 1: Energy-saving configuration information includes: at least one DRX cycle start offset, and / or, the activation order of at least one DRX cycle start offset.

[0105] The network configures multiple DRX cycle start positions, also known as DRX duration start positions, through RRC signaling to achieve dynamic or semi-static DRX start offset adjustment to align with the non-positive integer frame periods of XR services.

[0106] like Figure 3 As shown, before the MCG and SCG exchange power-saving configuration information, they can each be configured with different DRX start positions. This misalignment of DRX start positions will increase the duration of PDCCH monitoring by the terminal, thereby affecting the terminal's power saving. Figure 4 As shown in Example 1, the interaction between the MCG and SCG (or the interaction between the target cell and the source cell during cell handover) involves at least one DRX cycle start offset, thereby reducing the terminal's PDCCH listening duration and achieving terminal energy saving. The purpose of this energy-saving configuration information interaction is to minimize... Figure 3 The DRX monitoring shown is interleaved between MCG and SCG to reduce terminal power consumption. Furthermore, the network can also exchange activation sequence configurations for at least one DRX start position.

[0107] As another optional embodiment, the configuration information of at least one DRX configuration and / or the activation order of the at least one DRX configuration can correspond to the above-mentioned multiple DRX configuration technologies;

[0108] Optionally, a DRX configuration may include at least one of the following:

[0109] DRX duration timer information;

[0110] DRX cycle start offset information;

[0111] Information about the DRX inactivity timer;

[0112] DRX retransmission related timer information;

[0113] DRX cycle length information, which includes at least one of long DRX cycle length and short DRX cycle length.

[0114] In at least one embodiment of this application, at least one set of time-domain pattern configuration information can be used for semi-static alignment and coverage; for example, when frames of non-positive integer periods of XR services arrive, thereby reducing unnecessary power consumption caused by mismatch.

[0115] Optionally, a set of time-domain pattern configuration information includes at least one of the following:

[0116] Information on the start time or start offset of the time-domain pattern;

[0117] Optionally, the start time of the time-domain pattern can be related to the start time of the business data.

[0118] Optionally, the start time of the time-domain pattern can be related to the start time of the first service data unit. The service data unit can be a service packet, an application data unit, or a data frame.

[0119] Length information of the time-domain pattern;

[0120] Periodic information of time-domain patterns;

[0121] The length information of each time window in the at least one time window;

[0122] The time interval information between adjacent time windows in the at least one time window; for example, the time interval information specifically includes: the time interval between the start times of adjacent time windows, or the time interval between the end times of adjacent time windows, or the time interval between the end time of one time window and the start time of another time window in adjacent time windows.

[0123] The association information between the temporal pattern and service information, wherein the service information includes at least one of the following: service type, service flow, and quality of service (QoS) flow;

[0124] Optionally, each time-domain pattern may correspond to one or more service types, service flows, or QoS flows. For example, time-domain pattern 1 corresponds to a DL (Downlink) XR video service with a period of 16.67ms, and time-domain pattern 2 corresponds to a DL XR video service with a period of 8.33ms.

[0125] The time-domain pattern includes DRX-related information.

[0126] Optionally, the DRX-related information of the DRX period contained in the time-domain pattern includes at least one of the following:

[0127] Number of DRX cycles;

[0128] Optionally, the time-domain pattern may include one or more DRX periods.

[0129] DRX cycle length information; optionally, the DRX cycle length information includes the length information of each DRX cycle contained in the time-domain pattern, or the total length of all DRX cycles in the time-domain pattern.

[0130] DRX cycle DRX duration timer information; optionally, the DRX cycle DRX duration timer information refers to the DRX duration timer length information.

[0131] Information about the DRX inactivity timer during the DRX cycle. Optionally, the DRX inactivity timer information during the DRX cycle refers to the length of the DRX inactivity timer.

[0132] Example 2: The interactive energy-saving configuration information is the configuration information of a time-domain pattern.

[0133] The network configures at least one time-domain pattern for the terminal, and the terminal cycles periodically according to this pattern. For example, each time-domain pattern is configured by the network to consist of multiple non-contiguous time windows. Figure 5 As shown, the network configuration includes a time-domain pattern comprising three time windows, each with a length of 8ms, and the interval lengths between the start positions of each time window being 16ms, 17ms, and 17ms, respectively.

[0134] For example, the network configuration time-domain pattern consists of multiple DRX cycles, and the relevant configuration parameters for each DRX cycle can be the same or different, such as... Figure 6 In the network configuration, a time-domain pattern consists of three DRX cycles. The parameters of the last two DRX cycles are identical. DRX cycle 2 and DRX cycle 3 are both 17ms long, but differ from the length of the first DRX cycle, which is 16ms. The DRX duration of all three cycles is 8ms.

[0135] The purpose of the aforementioned time-domain pattern configuration is to semi-statically match the arrival of frames with non-positive integer periods in XR services. Network configurations or protocols stipulate that the terminal employs corresponding PDCCH listening behaviors within the time window of the time-domain pattern, scheduling and listening to XR frames. The exchange of the aforementioned time-domain pattern configuration information allows the MCG to understand the SCG's time-domain pattern configuration and facilitates alignment between the MCG and SCG's time-domain patterns, achieving better matching of the non-positive integer period characteristics of XR services, improving communication performance, and reducing data scheduling latency. Furthermore, the alignment of the time window length configuration between the MCG and SCG through information exchange further reduces the misalignment of PDCCH listening durations between the MCG and SCG, allowing their PDCCH listening to overlap as much as possible in the time domain, thereby reducing power consumption and achieving terminal energy saving.

[0136] In at least one embodiment of this application, the energy-saving indicator configuration information includes at least one of the following:

[0137] The Power Saving Wireless Network Temporary Identifier (PS-RNTI) is used for scrambling DCI format 2-6 Cyclic Redundancy Check (CRC).

[0138] Energy-saving offset, which is used to determine the detection start time of the DCI format 2-6;

[0139] Size information for DCI format 2-6;

[0140] Location information of energy-saving indicator in DCI format 2-6; where the location information of energy-saving indicator in DCI format 2-6 is for a specific terminal, it can also be referred to as: the location information of the energy-saving indicator corresponding to the terminal in DCI format 2-6;

[0141] Energy-saving wake-up information, which is used to wake up the terminal when the terminal does not detect DCI format 2-6;

[0142] First energy-saving indication information, the first energy-saving indication information is used to instruct the terminal to transmit periodic layer-1 reference signal received power RSRP reports without enabling the DRX duration timer;

[0143] The second energy-saving indication information is used to instruct the terminal to transmit periodic channel status information (CSI) reports other than periodic layer-1 RSRP reports without enabling the DRX duration timer.

[0144] Among them, the energy-saving RNTI scrambled DCI format 2-6 can be simply referred to as DCP.

[0145] Example 3: Interactive energy-saving configuration information includes: energy-saving indicator configuration information.

[0146] For example, the MCG sends energy-saving instruction configuration information to the SCG, which can then refer to this information to configure its own energy-saving features. The maximum value for PS-offset (energy-saving offset) can be 15ms, meaning the network can configure the DCP listening timing within a 15ms range before the start of the DRX cycle.

[0147] For example, such as Figure 7 as well as Figure 8 As shown, the network configuration includes the DCP configuration of the MCG, as well as the search space group and associated CORESET parameters corresponding to the MCG's DCP (DCI2-6), including: listening timing, listening period, listening duration, etc. The network also configures the DCP configuration of the SCG, as well as the search space group and associated CORESET parameters corresponding to the MCG's DCP (DCI2-6).

[0148] in, Figure 7 The MCG and SCG did not exchange DCP information. Figure 8 After the MCG and SCG in the middle were aligned through DCP information exchange, energy saving of the terminal was achieved.

[0149] In at least one embodiment of this application, the configuration information of the wake-up channel or wake-up signal includes at least one of the following:

[0150] Information on the timing of listening to the wake-up channel or wake-up signal;

[0151] Information on the monitoring cycle of the wake-up channel or wake-up signal;

[0152] Information on the duration of the wake-up channel or wake-up signal monitoring opportunity;

[0153] Time-frequency domain resource information of the wake-up channel or wake-up signal; for example, the time-frequency domain pattern of the wake-up signal;

[0154] The monitoring time window information of the wake-up channel or wake-up signal; wherein, the terminal listens for the wake-up indication at the monitoring time of the wake-up channel or wake-up signal within the monitoring time window;

[0155] The wake-up indication information carried by the wake-up channel or wake-up signal; for example, an index, a bitstring, or a bitmap; for example, the wake-up indication carried by the wake-up channel or wake-up signal is used to indicate the duration for which listening to at least one of the wake-up channel, wake-up signal, and PDCCH is skipped. For example, the specific content of the wake-up indication may include: an index value indicating the duration for which PDCCH listening is skipped, or an index value indicating the duration for which listening to the wake-up channel or wake-up signal is skipped.

[0156] The information refers to the mapping relationship between the wake-up indication and the wake-up indication bits. It should be noted that the wake-up indication refers to the specific content of the wake-up indication. For example, if the network can be configured with 2 bits for the wake-up indication, then the mapping relationship between the specific content of the wake-up indication and these two bits needs to be configured.

[0157] The frequency hopping format information of the wake-up signal;

[0158] The wake-up signal sequence information, including the sequence index and sequence generation method;

[0159] Information regarding the association between the wake-up channel or wake-up signal and the search space group;

[0160] Optionally, the wake-up signal or the association between the wake-up signal and the search space group refers to the following: when the terminal receives different wake-up signals, it switches to the search space group associated with them to listen for the target content. The association between the wake-up signal and the search space group is configured by the network-side device or agreed upon by the protocol. For example, wake-up signal 1 is associated with search space group 1; wake-up signal 2 is associated with search space group 2. When the terminal receives wake-up signal 2, the terminal switches to search space group 2 to listen for the target content.

[0161] RNTI information used to scramble the first DCI, wherein the first DCI carries the wake-up indication;

[0162] Size information of the first DCI;

[0163] The wake-up indication is the starting position information in the first DCI.

[0164] Optionally, the configuration information of the wake-up channel or wake-up signal may further include: the starting position information of the wake-up indication associated with the terminal in the first DCI.

[0165] As an optional embodiment, the listening time window information of the wake-up channel or wake-up signal includes at least one of the following:

[0166] The duration of the listening time window, also known as the duration or length of the listening time window;

[0167] The starting position of the listening time window;

[0168] The offset of the starting position of the listening time window relative to the starting position of the DRX cycle;

[0169] The end position of the listening time window;

[0170] The offset of the end position of the listening time window relative to the start position of the DRX cycle;

[0171] The period of the monitoring time window can be matched with, for example, the DRX period or the business period.

[0172] Example 4: The energy-saving configuration information of the interaction is the configuration information of the wake-up signal, which can be called WUS;

[0173] XR is a periodic service, but the arrival time of each XR frame at the network varies relative to the ideal periodic arrival time. Therefore, to cope with this XR packet jitter, the network configures WUS listening timing (MO) to achieve a balance between minimizing scheduling latency and power saving at the terminal. For example... Figure 9 and Figure 10 As shown, the network is configured with WUS monitoring settings for both MCG and SCG, including the wake-up indicator monitoring time window, WUS MO, WUS monitoring period, etc. Furthermore, in this example, the start and end positions of the wake-up indicator monitoring time window are configured relative to the start and end positions of the DRX duration.

[0174] Because XR has a very large jitter range, the listening time window range of the WUS MO configured on the network side will also be relatively large. If the MCG and SCG are configured independently and do not exchange information, it will lead to... Figure 9 In this case, the listening time windows of MCG and SCG are interleaved in the time domain, resulting in a very long listening time for the terminal and excessive power consumption.

[0175] This example demonstrates how the configuration information for waking up the indicator is accessed through interaction between the MCG and SCG, enabling features such as... Figure 10 The effect is that if the wake-up indication configurations of MCG and SCG can be aligned, the terminal's listening time will be reduced, thus saving power.

[0179] The mapping relationship between the duration of skipped PDCCH listening and the skipped PDCCH listening indicator bit; for example, if the skipped PDCCH listening indicator bit is 2 bits, the mapping relationship is as follows: the duration of skipped PDCCH listening 1 corresponds to indicator bit "00"; the duration of skipped PDCCH listening 2 corresponds to indicator bit "01"; the duration of skipped PDCCH listening 3 corresponds to indicator bit "10"; and the duration of skipped PDCCH listening 4 corresponds to indicator bit "11".

Alternatively, the energy-saving configuration information alignment instruction is used to instruct the SCG's own energy-saving configuration information to be a subset of the MCG's energy-saving configuration information.
