[0265] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. By way of example, the network device may include an access network device and a core network device.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0278] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0279] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0280] In some cases, IoT devices are often powered by traditional batteries with limited lifespans, negatively impacting the user experience. The expected astronomical growth in the number of IoT network devices, coupled with the massive number of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0281] In some implementations, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), have been developed to meet the growing demands of various vertical sectors. These LPWA technologies offer low cost, low power consumption, and large-scale connectivity, meeting the requirements of many applications. However, many use cases and applications remain unaddressed. First, battery-powered devices are not suitable, such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, and humid environments). Second, maintenance-free devices are required (e.g., devices without traditional batteries requiring replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., mm thickness), and extended lifecycles are required. Ambient-powered IoT devices are promising technologies that can address these unmet needs. Ambient-powered IoT devices are IoT devices powered by energy harvesting, either without batteries or with limited energy storage capabilities (e.g., using capacitors). Energy is collected from radio waves, light, motion, heat, or any other suitable power source.

[0282] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0283] The main application scenarios of the fifth generation mobile communication technology (5th Generation, 5G) are enhanced mobile broadband (eMBB), ultra reliable low latitude communication (URLLC), and massive machine type communication (mMTC).

[0284] eMBB continues to focus on providing users with multimedia content, services, and data, and demand for this technology is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it's not possible to generalize and requires detailed analysis based on specific deployment scenarios.

[0285] Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), traffic safety, etc.

[0286] Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost and long service life.

[0287] In the early days of New Radio (NR) deployment, complete NR coverage was difficult to achieve. Therefore, typical network coverage consisted of wide-area Long Term Evolution (LTE) coverage and NR island coverage. Furthermore, a large number of LTE deployments operate below 6 GHz, leaving limited spectrum available for 5G. Spectrum applications above 6 GHz suffer from limited coverage and rapid signal fading. To protect mobile operators' initial investments in LTE, a tight interworking mode between LTE and NR was proposed.

[0288] To improve data rates, Multi-Rate Dual Connectivity (MR-DC) was proposed. MR-DC is a generalized dual connectivity of the Evolved Universal Terrestrial Radio Access (Intra-E-UTRA) of the Universal Mobile Telecommunication System (UMTS).

[0289] As shown in Figure 1B, MR-DC can include EN-DC, NG EN-DC, NE-DC, and NR-DC. The main differences are whether the MN in the two base station nodes implementing DC is a gNB or an eNB, and whether the core network connected is the Evolved Packet Core (EPC) or the 5th Generation Core (5GC).

[0290] 5G terminals consume very high amounts of energy. To address this, numerous energy-saving technologies have been introduced, including C-DRX (supported by both 4G and 5G) and measurement relaxation. Different DCs utilize the core network (CN), master node (MN), and / or secondary node (SN).

[0291] In order to further achieve terminal energy saving, WUS (wake up signal) is introduced for radio resource control connection (RRC_CONNECTED) terminal energy saving. An offset in front of the wake-up period (on duration) of the terminal connection state discontinuous reception (Connectivity-discontinuous reception, C-DRX) is used to define a WUS transmission period. WUS is sent during the transmission period of the WUS. The WUS can be downlink control information (Dwonlink Control Information, DCI) format 2-6, and is scrambled by the power saving radio network temporary identity (Power Saving Radio Network Temporary Identity, PS-RNTI) to indicate whether the terminal wakes up to monitor PDCCH in the next terminal C-DRX wake-up period.

[0292] To save energy in RRC idle / inactive (RRC_IDLE / INACTIVE) terminals, a paging wake-up signal (Paging WUS) is introduced. This WUS is sent at a certain moment before the paging occasion (PO). This Paging WUS, also known as the Paging Early Indication (PEI), indicates whether the terminal is monitoring paging scheduling information at the PO. The PEI corresponds to DCI 2-7 and is scrambled using the Paging Early Indication Radio Network Temporary Identifier (PEI-RNTI).

[0293] To further achieve terminal energy conservation, a low-power wake-up signal receiver (LP-WUR) is introduced, as shown in Figure 1C. In the LP WUS (Low Power Wake Up Signal) technology, the base station sends a low-power wake-up signal to the terminal to wake up the terminal whose main transceiver is asleep. At this time, the terminal's main transceiver is asleep, and a separate low-power receiver is used to receive the LP WUS. After receiving the LP WUS, the terminal's main receiver can be awakened to perform data transmission and reception operations, etc. The power consumption of the terminal's low-power receiver is much lower than that of the terminal's main receiver.

[0294] For terminals in the RRC_CONNECTED state, C-DRX is configured to achieve discontinuous reception (DRX) for the terminal, saving power. To further reduce power consumption, C-DRX's WUS (DCP) is introduced. WUS is monitored during a pre-configured time period before the DRX wake-up period. The WUS indicates whether to monitor the PDCCH during the following DRX wake-up period.

[0295] Current WUS and C-DRX methods are not sufficiently power-efficient. Therefore, the introduction of low-power receivers can further improve power savings. However, controlling the transmission and reception of connected LP-WUS remains an issue that needs to be addressed.

[0296] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0297] S2101: The terminal sends capability information to the access network device.

[0298] In some embodiments, the terminal may be various types of terminals.

[0299] Exemplarily, the terminal has a first transceiver and a second transceiver.

[0300] In some embodiments, the power consumption of the first transceiver is lower than the power consumption of the second transceiver. For example, the power consumption of the first transceiver in an operating state is lower than the power consumption of the second transceiver in an operating state.

[0301] In some embodiments, the sensitivity of the first transceiver is lower than the sensitivity of the second transceiver.

[0302] In some embodiments, the first transceiver supports reception alone, that is, the first transceiver may be a separate receiver. For example, the first transceiver may include but is not limited to LP-WUR.

[0303] In some embodiments, the transmission capability of the first transceiver is weaker than the transmission capability of the second transceiver.

[0304] In some other embodiments, the second transceiver may be a main radio (MR) of the terminal.

[0305] In some embodiments, the terminal may shut down or put the second transceiver into hibernation to save power consumption. At this time, the first transceiver monitors the first signal sent by the access network device, and the terminal determines whether to wake up the MR based on the monitoring of the first signal.

[0306] In some embodiments, the terminal may have one first transceiver. The first transceiver may receive signals for the entire UE or different FRs or different BWPs or different frequency bands.

[0307] In other embodiments, the terminal may have multiple first transceivers. For example, the terminal may have two first transceivers. Furthermore, the terminal may have two LP-WURs. LP-WURs may also be abbreviated as LRs.

[0308] In some embodiments, the access network device may be a service access network device of the terminal.

[0309] Access network equipment is equipment on the network side. There can be one or more access network equipment on the network side.

[0310] In some embodiments, the terminal sends capability information to its own service access network device.

[0311] In a single-connection scenario of a terminal, the terminal can send capability information to one access network device, which can be the serving access network device of the terminal and can be called the first access network device. When the serving access network device receives the capability information of the terminal, it can send the capability information of the terminal to the second access network device when the terminal requests cell switching. At this time, the second access network device can be the access network device of the target cell for the terminal cell switching. In some cases, when the terminal performs cell reselection, the terminal sends capability information to the previous serving access network device (corresponding to the first access network device). Then, the current serving access network device of the terminal (corresponding to the second access network device) can obtain the capability information of the terminal from the previous serving access network device.

[0312] In a dual-connection scenario, the terminal's service access network device can be divided into a primary node and a secondary node. In this case, the primary node can be considered the first access network device, and the secondary node can be considered the second access network device.

[0313] A primary node typically provides a terminal's primary cell. A secondary node provides a terminal's secondary cell. A secondary cell can be configured with both primary and secondary cells. While a standard secondary cell typically does not transmit control signaling and only transmits service data, primary and secondary cells can transmit control signaling. Nodes configured with primary and secondary cells for a terminal are referred to as primary and secondary nodes.

[0314] In some embodiments, the terminal may send capability information to the master node.

[0315] In other embodiments, the terminal may send capability information to the primary and secondary nodes.

[0316] In some embodiments, the terminal sends the capability information to the access network device via a physical layer message and / or a higher layer message. Exemplarily, the terminal sends the capability information to the terminal via user assistance information. Exemplarily, the terminal sends the capability information to the terminal via a message such as an RRC connection request or an RRC connection recovery.

[0317] In some embodiments, the capability information is used by the access network to determine whether the terminal supports first signal reception.

[0318] In some embodiments, the capability information is used by the access network device to determine whether the terminal has a first transceiver for receiving the first signal, etc.

[0319] In some embodiments, the capability information is used by the access network device to determine configuration information of the first signal.

[0320] In some embodiments, the capability information may be specifically used to indicate at least one of the following:

[0321] whether the terminal supports receiving the first signal;

[0322] whether the terminal has a first transceiver;

[0323] the number of first transceivers of the terminal;

[0324] the number of first signals that the terminal supports receiving simultaneously;

[0325] Frequency information of the first signal supported by the terminal;

[0326] whether the terminal supports time division multiplexing to receive the first signal;

[0327] The number of first signals that can be received simultaneously by the terminal when receiving the first signal using time division multiplexing.

[0328] In some embodiments, if the terminal sends capability information, the access network device may receive the capability information of the terminal from the terminal.

[0329] In other embodiments, the terminal may not send capability information, and the access network device may request the capability information of the terminal from the core network device. For example, the terminal may receive the capability information of the terminal from the User Data Management (UDM) of the core network.

[0330] S2102: The access network device sends configuration information.

[0331] In some embodiments, before sending the configuration information, the access network device generates the configuration information based on the capability information of the terminal.

[0332] In some embodiments, when the terminal has the first transceiver or supports first signal reception, configuration information is generated according to the capability information of the terminal. The generated configuration information may be one or more sets.

[0333] In some embodiments, before sending configuration information, the access network device may also receive configuration information from other access network devices.

[0334] In some embodiments, the second access network device may receive configuration information from the first access network device.

[0335] The configuration information may be one or more sets.

[0336] In some embodiments, different sets of configuration information may have different configuration identifiers.

[0337] In some embodiments, different sets of configuration information may be sent to the terminal via different messages.

[0338] In other embodiments, different sets of configuration information may be targeted at different first signals.

[0339] In some other embodiments, different sets of configuration information have different at least one parameter for the first signal.

[0340] For example, in a dual-connectivity scenario, a terminal may have multiple service access network devices, that is, multiple access network devices provide services for the terminal.

[0341] In some embodiments, a first access network device generates a set of first configurations. The set of first configurations is used by the first access network device to send one or more first signals to a first transceiver of a terminal. When sending multiple first signals, different first signals have different time-frequency resources, flag bits, scrambling codes, encoding, and / or indicator bits.

[0342] In some embodiments, a first access network device generates a set of first configurations, which can be used for sending two first signals. The set of first configurations includes difference parameters. The difference parameters can be used for the first access network device and the second access network device to send different first signals. The difference parameters may include: differences in time-frequency resources for sending the first signals, encoding information, scrambling code information, flag bit information and / or waveform information, etc. The encoding information is used to distinguish the encoding of the two first signals. The scrambling code information is used to distinguish the scrambling codes used by the two first signals. The first signals sent by the first access network device and the second access network device may carry different flag bits and / or indicator bits.

[0343] In some embodiments, the indication bit may indicate information such as a cell identifier, a cell index, a node identifier, a node index, and / or a targeted frequency range, a BWP, and the like.

[0344] In some embodiments, a first access network device generates two sets of first configurations: one set of first configurations for the first access network device to send a first signal, and another set of first configurations for the second access network device to send a first signal. The two sets of first configurations differ in at least some parameters, thereby enabling the first signals of the first access network device and the second access network device to be distinguished. In some embodiments, the first access network device and the second access network device each generate their own configuration information. For example, the first access network device generates a second configuration for itself to send a first signal to a terminal. The second access network device generates a third configuration for itself to send the first signal to the terminal.

[0345] In some embodiments, the master node generates configuration information. The configuration information generated by the master node may be one or more sets. One set of configuration information may be used for one first signal. The configuration information generated by the master node may be used to transmit the first signal to the master node and / or the slave node.

[0346] In other embodiments, the primary node and the secondary node each configure configuration information. In this case, the primary node and the secondary node each may generate multiple sets of configuration information.

[0347] In some embodiments, a set of configuration information may also be used for transmitting multiple first signals. Different sets of configuration information may have at least one parameter that is different.

[0348] In some embodiments, when a set of configuration information is used for transmission of multiple first signals, the multiple first signals may share most parameters of the set of configuration information and the set of configuration information sets one or more parameters for different sets of first signals.

[0349] In other embodiments, a set of configuration information may be used for transmitting multiple first signals with different encodings, different indication bits or different flag bits or different waveforms.

[0350] For example, different encodings indicate that the first signal is encoded in different ways. For example, two first signals correspond to a sequence of length M, and the two sequences are at least different. First signals using different sequences may be first signals with different encodings.

[0351] The first signal with different waveforms is transmitted by the access network device using different waveforms. For example, some first signals may use an on-off keying (OOK) waveform, while others may use waveforms other than the OOK waveform.

[0352] For example, for two first signals, the flag bit may be one bit, and the two values ​​of "0" and "1" of the bit may distinguish the two first signals.

[0353] For another example, the first signal may carry an indication bit in addition to the sequence. The indication bit may carry cell information, access network device information, targeted FR information, targeted BWP information, and / or targeted frequency band information.

[0354] Such information may include an identifier and / or an index. For example, prioritizing the use of an index may reduce the number of bits indicating the bit love smile.

[0355] Before generating configuration information, access network devices can exchange terminal capability information with each other. For example, the access network device of the source cell, upon obtaining the terminal's capability information, can send it to the access network device of the terminal's target cell. For another example, the primary node of a terminal, upon obtaining the terminal's capability information, can send it to its secondary node. For another example, the secondary node, upon obtaining the terminal's capability information, can provide it to the primary node of the terminal.

[0356] The terminal's capability information may be carried in an Xn message transmitted between access network devices. The Xn message may be a message transmitted via an Xn interface.

[0357] In some embodiments, an access network device may support multiple bandwidth parts (BWPs), multiple frequency ranges (FRs), or multiple frequency bands. The access network device may configure different first signals for different frequency bands, different FRs, or BWPs.

[0358] In some embodiments, in a dual-connectivity scenario, the primary node sends configuration information. The primary node sends configuration information for sending the first signal itself. Alternatively, the primary node sends configuration information for both itself and the secondary node to send the first signal. The secondary node herein at least cannot include the primary and secondary nodes among the secondary nodes.

[0359] Exemplarily, the master node sends a first configuration, and the first configuration is used for the master node and / or the slave node to send a first signal.

[0360] In another exemplary embodiment, the master node sends a second configuration, and the slave node sends a third configuration. The second configuration is used for the master node to send at least one first signal. The third configuration is used for the slave node to send at least one first signal.

[0361] The first configuration, the second configuration, and the third configuration here are all the aforementioned configuration information.

[0362] In some other embodiments, in a dual-connectivity scenario, the primary node and the secondary node respectively send configuration information for sending their respective first signals.

[0363] In some embodiments, the first signal may be various power saving signals, such as LP-WUS.

[0364] In some embodiments, the access network device broadcasts, multicasts, or unicasts the configuration information.

[0365] In some embodiments, in a dual-connection scenario, the terminal may exchange information between a primary node and a secondary node, and generate configuration information based on the exchanged information.

[0366] Exemplarily, the access network device sends the configuration information, and the terminal receives the configuration information.

[0367] In some embodiments, a terminal receives a set of configuration information sent by an access network device; wherein the set of configuration information is for configuration of one or more first signals; wherein at least one of time-frequency resources, coding, flag bits, or indicator bits of the multiple first signals targeted by the set of configuration information is different;

[0368] In some embodiments, a terminal receives multiple sets of configuration information sent by an access network device; wherein each set of configuration information in the multiple sets of configuration information is for configuration of a first signal, and the first signal is used for different frequency resources, different access network devices, different cells, and / or different first transceivers of the terminal;

[0369] In some embodiments, the terminal receives multiple sets of configuration information sent by different access network devices; wherein, the multiple sets of configuration information sent by different access network devices are for the configuration of a first signal or for the configuration of one or more first signals, and the first signal is used for different frequency resources, different access network devices, different cells and / or different first transceivers of the terminal.

[0370] In some embodiments, the configuration information includes at least one of the following:

[0371] A frequency indication, used to indicate a frequency resource targeted by the first signal;

[0372] Type information, used to indicate the type of the first signal;

[0373] Period information, used to indicate a period for sending the first signal and / or a duty cycle of the period;

[0374] Channel information, used to indicate the channel or sub-channel on which the first signal is sent;

[0375] Scrambling code information, used to indicate a first scrambling code used by the first signal, where different terminals correspond to different scrambling codes;

[0376] Time information, used to indicate the validity period of the configuration information;

[0383] Shift information, used to indicate a time domain offset for waking up the second transceiver;

[0384] The pattern information is used to indicate a sending pattern of the first signal.

[0385] In some embodiments, the frequency indication may indicate a FR, a BWP, or a frequency band for which the first signal is intended.

[0386] In some embodiments, the period information may be used to indicate a transmission period of a first signal. The period may be statically configured or semi-statically configured. The duty cycle of the period may be used to indicate the duration of the first transmission within a period.

[0387] On which channels or sub-channels the first signal is sent.

[0388] Different terminals may share the same configuration information, and if it is necessary to implement the wake-up of the second transceiver of a specific terminal, the different first scrambling codes of the first signal may be synchronized to distinguish them.

[0389] The time information can be directly used to determine the time period during which each first signal is continuously sent.

[0390] The region information may indicate the scope to which the configuration information applies.

[0391] In some embodiments, the configuration information may be applicable to one cell or multiple cells. For example, the configuration information may be applicable to multiple adjacently distributed cells, so that when the terminal moves between different cells in a region, it can receive the first signal based on the same configuration information.

[0392] In some embodiments, the configuration information may be sent via high-layer signaling and activated or deactivated via MAC layer or physical layer signaling, which may be referred to as activation signaling or deactivation signaling. To reduce the bit overhead of the activation signaling or deactivation signaling, the activation signaling or deactivation signaling may be scrambled using a second scrambling code, so that the activation signaling or deactivation signaling may not carry an identifier of the corresponding configuration information.

[0393] In some embodiments, the first signal is transmitted using a beam. The beams on which the first signal is transmitted and the beam sweep period determine the transmission parameters used by the access network device to transmit the first signal. These parameters are indicated by beam information. In some embodiments, the configuration information sent by the access network device to the terminal may not include beam information. However, configuration information exchanged between different access network devices may include beam information.

[0394] In some embodiments, different first signals may have different waveforms, so that the first signals can be distinguished by the waveform. In some embodiments, the first signal may use a simple waveform such as OOK, which facilitates the terminal to receive and decode the first signal with extremely low power consumption.

[0395] In some embodiments, when the first transceiver receives the first signal, the second transceiver is immediately awakened.

[0396] In some other embodiments, after the first transceiver receives the first signal, the terminal may wake up the second transceiver a certain time after the moment of receiving the first signal according to the offset information, that is, the second transceiver wakes up with delay.

[0397] In short, the second transceiver is awakened immediately or with a delay, which can meet the requirements of different delay tolerances on the network side for service data to reach the terminal, or for calling the terminal.

[0398] In some embodiments, the pattern information may further include a time domain pattern and / or a frequency pattern, and the time-frequency resources of one or more first signals may be called through the pattern information.

[0399] In some embodiments, the pattern information indicates at least one of the following:

[0400] A time domain pattern, used to indicate a time domain position of a first signal;

[0401] The time division multiplexing TDM pattern is used to indicate the sending time domain positions of different first signals.

[0402] If the plurality of first signals are sent using a time division multiplexing manner, the terminal can receive the first signals using a first transceiver that is smaller in number than the number of the first signals, thereby simplifying the structure of the terminal.

[0403] In some embodiments, the type of the first signal includes at least one of the following:

[0404] A first signal of a terminal;

[0405] a first signal in a frequency range FR;

[0406] a first signal of a plurality of FRs;

[0407] A first signal of a partial bandwidth BWP;

[0408] a first signal of a plurality of BWPs;

[0410] The first signal of one terminal will be used to wake up the second transceiver of the entire terminal.

[0411] In some embodiments, a first signal for one frequency range is used to wake up a second transceiver of a terminal in a corresponding frequency range.

[0412] The first signals of the multiple FRs will be used to wake up any second transceiver of the terminal corresponding to these FRs.

[0413] The first signal of a BWP will be used to wake up the second transceiver of the terminal corresponding to the BWP.

[0414] The lower-than signals of the multiple BWPs will be used to wake up the second transceiver of the terminal corresponding to any one or more of the multiple BWPs.

The MN sends first signals targeted at different BWPs, different FRs, different cells, or different access network devices of the terminal based on the configuration information. Upon receiving the corresponding first signal, the first transceiver of the terminal wakes up the corresponding second transceiver.

[0425] In some embodiments, the terminal has a first transceiver. In this case, the terminal may receive the first signal as follows:

[0432] Exemplarily, in a single connection scenario of the terminal, the terminal may use one first transceiver to send one first signal from the access network device, or different first signals sent for different frequency ranges.

[0433] In some embodiments, the terminal has a plurality of first transceivers. In some embodiments, the terminal has two first transceivers.

[0434] In a dual-connection scenario, the terminal can receive the first signal sent by the primary node or the secondary node at different frequency layers and at different time points.

[0439] In some embodiments, in a dual-connection DC scenario, the terminal receives a first signal sent by the master node.

[0443] In some embodiments, the terminal determines whether to wake up the second transceiver or how to wake up the second transceiver based on the type of the received first signal. For example, if the terminal has multiple second transceivers, the terminal wakes up the corresponding second transceiver based on the second transceiver corresponding to the first signal. For another example, if the terminal has one or more second transceivers, the terminal wakes up the second transceiver belonging to the corresponding RF link based on the FR corresponding to the first signal received by the first receiver.

[0569] S4106: The first access network device sends third information.

[0570] In some embodiments, the third information is used to indicate that the first access network device wakes up the second transceiver of the terminal through the first signal.

[0571] In some embodiments, the third information may be used to instruct the first access network device to wake up the BWP, frequency band and / or FR corresponding to the second transceiver of the terminal through the first signal.

[0572] In some embodiments, the first access network device sends an Xn message carrying third information to the terminal.

[0573] S4107: Receive fourth information sent by the second access network device.

[0574] In some embodiments, the fourth information is used to indicate that the second access network device has woken up the second transceiver of the terminal through the first signal.

[0575] In some cases, the second access network device sends the first signal according to the third configuration, and the second transceiver of the terminal has been awakened, but the first access network device may not be aware of it.

[0576] S4108: Receive the fifth information sent by the terminal.

[0577] In some embodiments, the fifth information is used to indicate that the second transceiver of the terminal has been awakened.

[0578] It is worth noting that some embodiments may include S4105, and the remaining steps are optional. For example, if the first signal is sent according to the protocol, there is no need to obtain the terminal's capability information or generate configuration information. If the first access network device is the terminal's sole serving base station, it is not necessary to inform the second access network device whether the terminal's second transceiver has been awakened, and steps S4106 to S4107 can be omitted.

[0579] Some embodiments may include: S4104 and S4105, and the remaining steps are optional steps. For example, in some cases, the first access network device may, according to the protocol agreement, be considered to perform unified configuration for all terminals in the cell that support first signal reception. At this time, it can be considered that these terminals have the same capabilities, and the first access network device can be directly configured. In this case, there is no need to receive the terminal's capability information from the terminal, the core network, or other access network devices. If the first access network device is a separate service base station for the terminal, it is not necessary to inform the second access network device whether the second transceiver of the terminal has been awakened, and steps S4106 to S4107 can be omitted.

[0580] Some embodiments may include: S4102. All other steps are optional. For example, the first access network device may not send the first signal. After receiving the capability information of the terminal, the first access network device sends the capability information to the second access network device. The second access network device generates configuration information based on the capability information and sends the first signal. In this case, all other steps may be omitted. If the second access network device does not send the first signal, the second access network device will not send the third information. Therefore, the first access network device does not need to receive the third information from the first access network device.

[0581] Some embodiments may include: S4102 and S4107. Other steps are optional. For example, the first access network device may not send the first signal. After receiving the capability information of the terminal, the first access network device sends the capability information to the second access network device, which then generates configuration information based on the capability information and sends the first signal. At this time, if the first access network device needs to know whether the second transceiver of the terminal has been awakened, or for which cell, BWP, FR, or frequency band the second transceiver has been awakened, it needs to receive fourth information from the second access network device.

[0582] Some embodiments may include: S4102 and S4108. Other steps are optional. For example, the first access network device may not send the first signal. After receiving the capability information of the terminal, the first access network device sends the capability information to the second access network device, which then generates configuration information based on the capability information and sends the first signal. At this time, if the first access network device needs to know whether the second transceiver of the terminal has been awakened, or for which cell, BWP, FR, or frequency band the second transceiver has been awakened, it needs to receive fifth information from the terminal.

[0583] Some embodiments may include S4105 and S4106. All other steps are optional. For example, the first access network device may not generate configuration information, but may directly send a first signal according to the protocol, and notify the second access network device by sending third information that the second transceiver of the current terminal and / or the cell, BWP, FR, or frequency band corresponding to the second transceiver has been awakened. Furthermore, the second access network device may not send the first signal, so the first access network device does not need to perform S4107 and / or S4108.

[0584] Some embodiments may include: S4103, S4104 and S4107, and other steps are optional steps. For example, the first access network device as a master node or a node of a service cell of a terminal is only responsible for generating and sending configuration information and may not send the first signal itself.

[0585] Some embodiments may include: S4103, S4104 and S4108, and other steps are optional steps. For example, the first access network device as a master node or a node of a service cell of a terminal is only responsible for generating and sending configuration information and may not send the first signal itself.

[0613] In some embodiments, the second access network device, as the SN, can obtain the capability information of the terminal and actively push it to the first access network device.

[0614] In some embodiments, the second access network device, serving as the SN, may consider that the MN is more likely to obtain capability information, and therefore does not send capability information to the MN when no instruction from the MN is received. That is, the SN sends capability information to the MN based on the instruction from the MN.

[0643] S5108: Receive the fifth information.

[0644] In some embodiments, fifth information is sent by the receiving terminal.

[0645] In some embodiments, the fifth information is used to indicate that the second transceiver of the terminal is awakened.

[0646] It is worth noting that some embodiments may include S5105, and the remaining steps are optional. For example, if the first signal is sent according to the protocol, there is no need to obtain the terminal's capability information or generate configuration information. When the second access network device awakens the terminal's second transceiver, the terminal will send fifth information to the first access network device, informing the first access network device whether its second transceiver is awakened, or which second transceiver is awakened.

[0647] Some embodiments may include: S5105 and S5107, and the remaining steps are optional steps. For example, if the first signal is sent according to the protocol, there is no need to obtain the terminal's capability information and generate configuration information.

[0648] Some embodiments may include: S5104 and S5105; the remaining steps are optional. For example, in some cases, the second access network device may receive the first configuration from the first access network or independently generate a third configuration based on the terminal capabilities agreed upon in the protocol and send the first signal. When the second access network device awakens the second transceiver of the terminal, the terminal sends fifth information to the first access network device, informing the first access network device whether its own second transceiver is awakened, or which second transceiver is awakened.

[0649] Some embodiments may include: S5104, S5105, and S5107, and the remaining steps are optional. For example, in some cases, the second access network device may receive the first configuration from the first access network or generate the third configuration by itself and send the first signal.

[0650] Some embodiments may include: S5102, and the other steps are optional steps. For example, the second access network device may not send the first signal. After the second access network device receives the capability information of the terminal, it sends the capability information to the first access network device, and the first access network device generates configuration information based on the capability information and sends the first signal. Then the other steps can be omitted.

[0651] Some embodiments may include: S5102 and S5106. The other steps are optional. For example, the second access network device may not send the first signal. After receiving the capability information of the terminal, the second access network device sends the capability information to the first access network device, and the first access network device generates configuration information based on the capability information and sends the first signal. At this time, if the second access network device needs to know whether the second transceiver of the terminal has been awakened, or for which cell, BWP, FR, or frequency band the second transceiver is awakened, it needs to receive third information from the first access network device.

[0652] Some embodiments may include S5102 and S5108. Other steps are optional. For example, the second access network device may not send the first signal. After receiving the capability information of the terminal, the second access network device sends the capability information to the first access network device, and the first access network device generates configuration information based on the capability information and sends the first signal. At this time, if the second access network device needs to know whether the second transceiver of the terminal is awakened, or for which cell, BWP, FR, or frequency band the second transceiver is awakened, it needs to receive fifth information from the terminal.

[0653] Some embodiments may include: S5105 and S5107, and the other steps are optional steps. For example, the second access network device does not generate configuration information, but directly sends the first signal according to the protocol agreement, and tells the first access network device by sending the fourth information that the second transceiver of the current terminal and / or the second transceiver corresponding to which cell, BWP, FR or frequency band is awakened. And the second access network device may not send the first signal, so the first access network device does not need to execute S5106 and / or S5108. If the first access network device has not awakened the second transceiver of the terminal or the first access network device does not send the first signal, the second access network device will not receive the third information from the first access network device.

[0654] The disclosed embodiments describe how to coordinate LP-WUS configurations in MR-DC scenarios. Specifically, they describe how a network device determines the number of LP-WUS configurations and how to notify another network device of the MR status during LP-WUS usage. This allows for efficient LP-WUS in MR-DC scenarios, coordinates the use of MR and LR, maximizes terminal energy savings, and reduces service latency.

[0655] Solution 1: The network's LP-WUS support capabilities and terminal LP-WUS capability definitions have been reported (prerequisite)

[0656] First, network devices exchange information about the network's ability to support LP-WUS at their respective cell or base station granularity. Optionally, network devices can also notify each other about the frequency information where the LP-WUS is located, or the type of spectrum where the LP-WUS is located. For example, this frequency information can indicate in-band LP-WUS, out-band LP-WUS, and the guard band between different LP-WUS.

[0657] Furthermore, network devices may notify each other of the above information via the following Xn interface messages.

[0658] The Xn interface information may include but is not limited to at least one of the following:

[0659] As shown in Figure 6A, the messages during the Xn Setup process;

[0660] As shown in FIG6B , messages in the next generation radio access network device configuration update (NG-RAN node Configuration Update) process.

[0661] For example, NG-RAN node 1 may send the terminal capability information it has obtained to NG-RAN node 2 in an Xn setup request. Alternatively, if it has not yet obtained the terminal capability information, NG-RAN node 1 may send an instruction to negotiate capability information to NG-RAN node 2 through an Xn setup request. NG-RAN node 2 has obtained the terminal capability information and, upon receiving the Xn setup request, returns an Xn setup response containing the capability information to NG-RAN node 1.

[0662] For example, NG-RAN node 1 may send the terminal capability information it has obtained to NG-RAN node 2 in an NG-RAN node configuration update. Alternatively, if it has not yet obtained the terminal capability information, NG-RAN node 1 may send an instruction to negotiate capability information to NG-RAN node 2 through an NG-RAN node configuration update. NG-RAN node 2 has obtained the terminal capability information and, after receiving the NG-RAN node configuration update, returns an NG-RAN node configuration update confirmation containing the capability information to NG-RAN node 1.

[0663] Optionally, after establishing an MR-DC relationship, the two base stations also need to synchronize the types of serving cells configured for the terminal by the two network devices. For example, the serving cells configured for the terminal can be FR1 cells, FR1 and FR2 cells, or FR2 cells. This assists the network in determining which LP-WUS to configure. Here, FR1 cells refer to cells in frequency range 1. FR2 cells refer to cells in frequency range 2.

[0664] The base station obtains the terminal's LP-WUS capability information. For example, the base station may obtain the terminal's LP-WUS capability information from the terminal. For example, the terminal reports the LP-WUS capability information. Alternatively, the network device obtains the LP-WUS capability information from the AMF. For example, the AMF pushes the LP-WUS capability information to the base station. In the MR-DC scenario, the SN obtains the terminal's capability information through the MN.

[0665] The terminal's ability to support LP-WUS may be at least one of the following:

[0666] One bit indication information, indicating support for LP-WUS or the presence of LP-WUR.

[0667] The number of LP-WURs and / or the FR types or frequency ranges supported by each LP-WUR;

[0668] The frequency range or band combination of signals that the LP-WUR can receive;

[0669] Indication of FR1 and FR2 or higher frequencies supported by LP-WUS;

[0670] The number of LP-WUS that LP-WUR can receive simultaneously;

[0671] Support the ability to receive LP-WUS in TDM mode;

[0672] The number of LP-WUS received in TDM mode.

[0673] It is worth noting that: in some cases, the exchange of terminal-to-LP-WUS capability information between different access network devices (nodes) in Solution 1 can be implemented separately.

[0674] Solution 2: MN and SN each configure their own LP-WUS:

[0675] As shown in Figure 8A , after the terminal enters the RRC_CONNECTED state, the base station obtains the terminal's LP-WUS capability information. If the terminal supports LP-WUS monitoring, the base station determines whether to provide LP-WUS configuration to the terminal based on the terminal's LP-WUS capability information. The mobile node and the network service provider (SN) each configure LP-WUS for the terminal via RRC signaling. Exemplarily, the MN and SN each configure LP-WUS for the terminal via dedicated RRC signaling, i.e., the MN and SN each send their respective LP-WUS configuration information to the terminal.

[0676] Before the MN and / or SN configures LP-WUS for a terminal, the MN sends LP-WUS configuration information or instructions to the SN. The SN also indicates the MN's LP-WUS configuration information or instructions in a response message. If a network device is not configured, no LP-WUS information is indicated. Through this interaction, the MN and SN can distinguish between the LP-WUSs they send, making it easier to distinguish between the LP-WUSs received from the MN and / or SN, and also facilitate the MN and SN to know the complete LP-WUS configuration information of the terminal.

[0677] If the terminal has only one LP-WUR and there are multiple LP-WUS that need to be received, the multiple LP-WUS can be from the same frequency layer or different frequency layers.

[0678] Option 1: If the terminal needs to receive LP-WUS from two network devices via time division multiplexing (TDM), the mobile node also indicates to the network node the configuration information for the TDM pattern. The TDM pattern is a bitmap with a period and corresponding bits for all time slots within the period. Each bit in the bitmap corresponds to a time slot and is used to indicate the slot in which the network device can send the LP-WUS. For example, a bit indicating 0 or a bit indicating 1 in the bitmap allows the network node to send the LP-WUS.

[0679] Option 2: If more than one LP-WUS comes from the same frequency layer, the LP-WUS indicates whether the LP-WUS is for FR1 or FR2, or a higher frequency. Alternatively, the LP-WUS indicates whether the LP-WUS comes from the MN or the SN.

[0680] Option 3: If more than one LP-WUS arrives from the same frequency layer, different LP-WUSes for different purposes are scrambled using different scrambling codes, based on network-side configuration. For example, different scrambling codes can be used to distinguish LP-WUSes for FR1, FR2, or higher frequencies. Alternatively, the LP-WUS can indicate whether it originates from the mobile network (MN) or the network service provider (SN).

[0681] If the terminal has only one LP-WUR and only one LP-WUS needs to be received, but this LP-WUS needs to indicate the wake-up for both the RF1 link and the RF2 link. For example, the LP-WUS indicates whether the LP-WUS is used for FR1 or FR2, or a higher frequency. Or the LP-WUS indicates whether the LP-WUS comes from the MN or the SN. Or the LP-WUS contains at least two bits, and each of the at least two bits corresponds to FR1 and FR2 respectively. Note that the wake-up bit corresponding to each FR, or the information is not necessarily 1 bit, this is just a simple example. The information in the LP-WUS can be associated with an FR indication, which acts on FR1, FR2 or a higher frequency.

[0682] If the terminal has at least two LP-WURs and there are multiple LP-WUSs to be received, the terminal determines which LP-WUR is used to receive the LP-WUS of which FR, or which network device sends the LP-WUS.

[0683] Each network device can be configured with at least one LP-WUS. An LP-WUS can be per terminal (per terminal) or per frame (per frame). Therefore, an LP-WUS can be per terminal, FR1, FR2, or higher. If the LP-WUS is a terminal, then upon receiving the LP-WUS, both the RF1 and RF2 links must be awakened. If the LP-WUS is FR1, then upon receiving the LP-WUS, the terminal will also wake up the RF1 link. FR2 is similar.

[0684] The LP-WUS configuration that the terminal may receive from the MN or SN may be one of the following:

[0685] LP-WUS for one terminal;

[0686] LP-WUS of FR1;

[0687] LP-WUS of FR2;

[0688] FR1 LP-WUS and FR2 LP-WUS.

[0689] The LP-WUS configuration information of each network device may include at least one of the following:

[0690] FR indication, for example, indicates whether it is applied on FR1, FR2, or a higher frequency.

[0691] Monitor the duty cycle of LP-WUS;

[0692] Monitor the frequency resources of LP-WUS;

[0693] Monitor the time resources of LP-WUS;

[0694] Subchannel index, for example, 20 subchannels with 5 MHz;

[0695] A time slot index, e.g., a time slot index within a period of time;

[0696] Scrambling code used to locate the terminal. For example, different terminals have different scrambling codes within a subchannel or a time slot. The terminal can determine whether the LP-WUS is sent to it by the network device based on whether it successfully decodes the LP-WUS.

[0697] The effective area of ​​LP-WUS;

[0698] Validity period of LP-WUS;

[0699] Specific RNTI used for LP-WUS activation or deactivation;

[0700] Waveform of LP-WUS;

[0701] Beam scanning involved in LP-WUS transmission;

[0702] The frequency offset and / or time offset for switching between MR and LR.

[0703] Any option of Solution 2 can be executed independently as an embodiment without being combined with other solutions and / or other steps. Of course, it can also be implemented in combination with other solutions.

[0704] Solution 3: As shown in FIG8B , the MN and the SN negotiate to configure FR1 LP-WUS, FR2 LP-WUS, or LP-WUS for a single terminal.

[0705] After the terminal enters RRC_CONNECTED, the base station obtains the terminal's LP-WUS capability information and decides to configure LP-WUS for the terminal.

[0706] In the MR-DC scenario, the MN decides to configure the LP-WUS. The LP-WUS configuration may indicate the LP-WUS type (per terminal or per FR), per node LP-WUS configuration, or common LP-WUS configuration.

[0707] The MN instructs the SN on the LP-WUS configuration request and informs the SN whether the configured LP-WUS is for the entire terminal or a single FR, and / or whether the LP-WUS is for FR1, FR2, or FR3. FR3 is different from FR1 and FR2. For example, the frequency range of FR3 is higher than that of FR2.

[0708] Optionally, the MN may also indicate to the SN configuration information or instructions regarding the LP-WUS. If a certain network device is not configured, no content regarding the LP-WUS is indicated.

[0709] For example, the MN may send an LP-WUS configuration request to the SN via the Xn interface, and the SN may send an LP-WUS configuration confirmation to the MN. The MN may send the confirmed LP-WUS to the terminal.

[0710] The SN will also indicate the MN's configuration information or instructions about LP-WUS in the response message. If a network device is not configured, no LP-WUS content will be indicated.

[0711] If the terminal has only one LP-WUR and there are multiple LP-WUS that need to be received, the multiple LP-WUS can be from the same frequency layer or different frequency layers.

[0712] Option 1: If the terminal needs to receive LP-WUS from two network devices via time division multiplexing (TDM), the mobile node also indicates to the network node the configuration information for the TDM pattern. The TDM pattern is a bitmap with a period and corresponding bits for all slots within the period. Each bit in the bitmap corresponds to a slot and indicates the slot in which the network device can send the LP-WUS. For example, a bit indicating 0 or a bit indicating 1 in the bitmap allows the network node to send the LP-WUS.

[0713] Option 2: If more than one LP-WUS comes from the same frequency layer, the LP-WUS indicates whether the LP-WUS is for FR1 or FR2, or a higher frequency. Alternatively, the LP-WUS indicates whether the LP-WUS comes from the MN or the SN.

[0714] Option 3: If more than one LP-WUS arrives from the same frequency layer, different LP-WUSes for different purposes are scrambled using different scrambling codes, based on network-side configuration. For example, different scrambling codes can be used to distinguish LP-WUSes for FR1, FR2, or higher frequencies. Alternatively, the LP-WUS can indicate whether it originates from the mobile network (MN) or the network service provider (SN).

[0715] If the terminal has at least two LP-WURs and there are multiple LP-WUSs that need to be received, the terminal determines which LP-WUR is used to receive the LP-WUS of which FR, or which network device sends the LP-WUS.

[0716] The configuration of LP-WUS that the terminal can receive can be one of the following: (This does not exclude the possibility of higher frequency FR in the future, such as FR3):

[0717] It is worth noting that any one of the options in Plan 3 can be implemented alone without combining with other options, and of course it can also be implemented in combination with other options.

[0718] Solution 4: Referring to FIG. 8C , the MN decides to configure FR1 LP-WUS, FR2 LP-WUS, or the entire terminal LP-WUS.

[0719] After the terminal enters RRC_CONNECTED, the base station obtains the terminal's LP-WUS capability information and decides to provide the terminal with LP-WUS configuration.

[0720] In the MR-DC scenario, the MN decides to configure the LP-WUS. The type of LP-WUS (per terminal or per FR) is configured by the MN.

[0721] The MN notifies the SN of the type of LP-WUS configured, whether it is per terminal or per FR, and whether it is FR1 or FR2. Optionally, the MN can also indicate the SN configuration information or instructions about the LP-WUS. If no configuration is available, no LP-WUS content is indicated.

[0722] Before step 2), the SN may request the configuration of an LP-WUS. The request message may indicate the type of LP-WUS, i.e., whether it is for the entire terminal or a single FR. If the LP-WUS type is for FR, then the LP-WUS is specifically for FR1 or FR2.

[0723] At least one LP-WUS can be configured. LP-WUS can be for the entire terminal or a single frame. Therefore, LP-WUS can be for the entire terminal, FR1, FR2, or a higher frequency. If it is for a single terminal, upon receiving the LP-WUS, both the RF1 and RF2 links must be awakened. If the link is RF1, upon receiving the link, the Radio Frequency (FR) 1 link must be awakened. FR2 is similar. The RF1 link can be considered to correspond to FR1. The RF2 link corresponds to FR2.

[0724] The LP-WUS configuration that the terminal can receive can be one of the following:

[0725] If the terminal has only one LP-WUR and there are multiple LP-WUS that need to be received, the multiple LP-WUS can be from the same frequency layer or different frequency layers.

[0726] Option 1: If the terminal needs to receive LP-WUS from two network devices via time division multiplexing (TDM), the mobile node (MN) will also indicate to the network node (SN) the configuration information for the TDM pattern. The TDM pattern is a bitmap with a period and corresponding bits for all slots within the period. Each bit in the bitmap corresponds to a slot and is used to indicate the time slot in which the SN can send the LP-WUS. For example, a bit indicating 0 or a bit indicating 1 in the bitmap allows the SN to send the LP-WUS.

[0727] Option 2: If more than one LP-WUS comes from the same frequency layer, the LP-WUS indicates whether the LP-WUS is for FR1 or FR2, or a higher frequency. Alternatively, the LP-WUS indicates whether the LP-WUS comes from the MN or the SN.

[0728] Option 3: If more than one LP-WUS arrives from the same frequency layer, different LP-WUSes for different purposes are scrambled using different scrambling codes, based on network-side configuration. For example, different scrambling codes can be used to distinguish LP-WUSes for FR1, FR2, or higher frequencies. Alternatively, the LP-WUS can indicate whether it originates from the mobile network (MN) or the network service provider (SN).

[0729] If the terminal has only one LP-WUR and only one LP-WUS to receive, but this one LP-WUS needs to indicate both RF1 link wakeup and RF2 link wakeup, then the LP-WUS indicates whether the LP-WUS is for FR1 or FR2, or a higher frequency. Or the LP-WUS indicates whether the LP-WUS comes from the MN or the SN. Or the LP-WUS contains at least two bits, each of which corresponds to FR1 and FR2 respectively. Note that the wakeup bit or information corresponding to each FR is not necessarily 1 bit. This is just a simple example. The information in the LP-WUS can be associated with an FR indication, indicating whether it is for FR1, FR2, or a higher frequency.

[0730] If the terminal has at least two LP-WURs and there are multiple LP-WUSs that need to be received, the terminal determines which LP-WUR is used to receive the LP-WUS of which FR, or which network device sends the LP-WUS.

[0731] It is worth noting that any one of the options in Plan 4 can be implemented alone without combining with other options, and of course it can also be implemented in combination with other options.

[0732] Solution 5: Referring to FIG. 7A to FIG. 7F , the LP-WUS transmission and LP-WUS reception scenarios:

[0733] In some embodiments, a terminal may have one LP-WUR or two LP-WURs.

[0734] Solution 5.1:

[0735] 7A , a network device provides a set of LP-WUS configurations. For example, a MN provides a set of LP-WUS configurations to a terminal.

[0736] This set of LP-WUS configurations can be used by a terminal to monitor LP-WUS in one or more FRs. For example, a terminal can monitor LP-WUS in FR1 and / or FR2 using a single LP-WUR to wake up the terminal's RF1 link and / or RF2 link. For example, the FR1 link and the FR2 link may correspond to different second transceivers, or the corresponding second transceivers may have different receive antennas.

[0737] For example, the LP-WUS may include one bit indicating whether to use FR1 or FR2.

[0738] As another example, the LP-WUS may include two bits indicating the frequency range links to be awakened, for example, one bit is set for each of the RF1 link and the RF2 link, so that one LP-WUS can awaken FR1 and / or FR2.

[0739] Solution 5.2:

[0740] As shown in Figure 7B, the network device provides a set of LP-WUS configurations. For example, the MN provides a set of LP-WUS configurations to the terminal.

[0741] The network device sends two LP-WUSs based on the LP-WUS configuration. For example, a network device sends two LP-WUSs. For example, the mobile node sends two LP-WUSs. An LP-WUR of the terminal monitors the two LP-WUSs.

[0742] For example, if different sets of LP-WUS are from the same frequency layer, the LP-WUS may include a flag indicating whether the LP-WUS is directed to FR1 or FR2. For another example, if different sets of LP-WUS are from the same frequency layer, the LP-WUS for different FRs may have different encodings.

[0743] As another example, in order to distinguish LP-WUSs of different FRs, a TDM pattern may be used to send the LP-WUS, which is equivalent to transmitting the LP-WUSs for different FRs on different time domain resources.

[0744] Solution 5.3:

[0745] As shown in Figure 7C, the network device configures a set of LP-WUS configurations for the terminal. This LP-WUS configuration can be used to send LP-WUSs for different FRs using different frequency layers. For example, the network device may send two sets of LP-WUSs to the terminal: one set for FR1 and the other for FR2. For example, the mobile network sends two sets of LP-WUSs to the terminal.

[0746] A terminal may have two LP-WURs, and one LP-WUR may be used to receive one set of LP-WUS.

[0747] Solution 5.4:

[0748] As shown in Figure 7D, two network devices each send an LP-WUS to the terminal. For example, the MN and SN each send an LP-WUS for the same frequency range to the terminal. This frequency range may include, but is not limited to, FR1 or FR2. The terminal may have an LP-WUR for receiving the LP-WUS.

[0749] Illustratively, the encoding of LP-WUS from different network devices is different.

[0750] As another example, the terminal uses a TDM pattern to receive LP-WUS messages from different network devices. For example, the terminal uses a TDM pattern to receive LP-WUS messages from the MN and SN. In this case, the MN and SN send LP-WUS messages to the terminal at different time domain locations.

[0751] Option 5.5:

[0752] Two network devices each use different LP-WUS configurations to send an LP-WUS. For example, the MN and SN each use their own LP-WUS to send an LP-WUS for a different FR. FRs herein may include, but are not limited to, FR1, FR2, and / or FRn. n may be 3, 4, or 5. FRn differs from FR1 and FR2. For example, the center frequency of FRn is lower than that of FR1 or higher than that of FR2.

[0753] An LP-WUR of the terminal uses a TDM pattern to monitor the LP-WUS from different network devices respectively.

[0754] Solution 5.6:

[0755] As shown in Figure 7F, two network devices send LP-WUS to the terminal respectively. For example, the MN and SN each send LP-WUS for different frequency ranges to the terminal. The frequency range may include but is not limited to FR1 and / or FR2.

[0756] The two LP-WURs of the terminal respectively receive LP-WUS sent by different network devices.

[0757] It is worth noting that any of the LP-WUS transmission and / or reception schemes in scheme 1.2 can be implemented independently or in combination with scheme 1.1. For example, the terminal first reports its own capability information, or the access network device obtains the terminal's capability information and then proceeds based on the capability information.

[0758] It is worth noting that any one of the options in Option 5 can be implemented alone without combining with other options, and of course it can also be implemented in combination with other options.

[0759] Solution 6: Referring to FIG8D , the MN and SN synchronize the MR activation status of the terminal:

[0760] Any network device activates MR through LP-WUS.

[0761] Example 1: The network device notifies another network device about the MR activation status through the Xn interface.

[0762] Example 2: The terminal notifies another network device about the status of MR activation.

[0763] If the service of one network device is inactive, the other network device is notified of the service inactivity or requests to deactivate the MR, and the other network device is assisted in deciding to issue a deactivation MR instruction.

[0764] It is worth noting that any one of the options in Option 6 can be implemented alone without combining with other options, and of course it can also be implemented in combination with other options.

[0765] The disclosed embodiments describe how to configure and coordinate LP-WUS configurations in MR-DC scenarios, how to determine the number of LP-WUS configurations, and how to notify another network device of the MR status during LP-WUS usage. This enables efficient and coordinated use of LP-WUS in MR-DC scenarios, maximizes terminal energy savings, and reduces service latency.

[0766] In the embodiment of the present disclosure, network devices can perform LP-WUS capability negotiation and intercommunication between terminals.

[0767] In the MR-DC scenario, the MN and SN negotiate LP-WUS configuration and resource coordination, and negotiate LP-WUS from two network devices (for example, the terminal has an LP-WUR).

[0768] In the MR-DC scenario, MR status synchronization and MR deactivation negotiation are performed.
