Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, a communication device, a chip system, a storage medium, and a program product. Background Art

[0002] A low power wake-up signal (LP-WUS) is a wake-up signal used to reduce the power consumption of user equipment (UE). When a UE is in idle or inactive state and within the coverage area of an LP-WUS, the UE can shut down its high-power primary receiver and activate its lower-power low-power wake-up receiver.

[0003] When the network device needs to page the UE, the UE's corresponding group information can be carried in the LP-WUS. When the UE receives the LP-WUS from the network device through the low-power wake-up receiver, and the LP-WUS includes the UE's corresponding group information, the UE can turn on the main receiver to monitor the paging message (paging) sent by the network device.

[0004] However, for a discontinuous reception (DRX) cycle, multiple groups of terminal devices monitoring the same paging occasion (PO) often only correspond to one opportunity to monitor LP-WUS, and one LP-WUS can generally only wake up one group of UEs. This method may cause some UEs to wait for the next DRX cycle, resulting in a large delay. Summary of the Invention

[0005] The embodiments of the present application provide a communication method, a communication device, a chip system, a storage medium, and a program product, which are conducive to reducing the communication delay of a terminal device.

[0006] In a first aspect, an embodiment of the present application proposes a communication method that can be applied to an access network device or a chip in an access network device, but the present application is not limited thereto. The method includes: determining first information, the first information being used to indicate a target parameter corresponding to each of a plurality of sets, and an offset and a number of subgroups of a low-power wake-up signal LP-WUS corresponding to each of the plurality of sets, the plurality of sets being sets divided for terminal devices monitoring the same paging occasion PO, the target parameter being used to indicate the terminal device to which it belongs based on its own corresponding target parameter; and sending the first information.

[0007] The method provided in the embodiment of the present application can indicate the correspondence between the terminal device and the set (which can also be understood as the offset of the LP-WUS) through the first information determined by the access network device, which is beneficial for the access network device to determine at which offset (offset) to send the LP-WUS and for the terminal device to determine at which offset to receive the LP-WUS. In this way, by configuring multiple offests for the LP-WUS corresponding to the terminal device monitoring the same PO and sending LP-WUS at different offsets to wake up the terminal devices in different sets, the purpose of waking up the terminal devices that monitor the same PO and belong to different sets in one DRX cycle can be achieved, which is beneficial to reducing the communication delay of some terminal devices.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: receiving second information from a core network device, the second information being used to page a first terminal device, the second information including a first target parameter corresponding to the first terminal device; sending a first LP-WUS, the first LP-WUS being sent at a position corresponding to a first offset, the first LP-WUS including first sub-group information; wherein the first sub-group is a group in a set to which the first terminal device belongs, the first offset and the first sub-group information are determined based on the first target parameter, according to the target parameter corresponding to each of a plurality of sets, and the offset and the number of sub-groups of the low-power wake-up signal LP-WUS corresponding to each of the plurality of sets.

[0009] In an embodiment of the present application, the access network device can determine, based on the first target parameter included in the second information and in combination with the first information, that the first terminal device receives the LP-WUS at the position corresponding to the first offset. Further, based on the number of subgroups corresponding to the set to which the first terminal device belongs, the first subgroup information corresponding to the first terminal device is determined, the first subgroup information is carried on the first LP-WUS, and the first LP-WUS is sent at the position corresponding to the first offset. This is conducive to enabling the paged first terminal device to accurately receive the first LP-WUS.

[0010] In combination with the first aspect, in some implementations of the first aspect, the target parameter includes one or more of the following: effective paging rate; false paging rate; main receiver startup duration; or main receiver startup power consumption.

[0011] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving a first target parameter reported by a first terminal device; and sending the first target parameter to a core network device when the first terminal device is about to enter an idle state.

[0012] In this way, it is beneficial for the core network device to obtain the first target parameter so as to page the first terminal device based on the first target parameter.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the target parameters, LP-WUS offset, and number of subgroups corresponding to each of the multiple sets, and the correspondence between each set are agreed upon by the protocol or indicated by the coding order.

[0014] In this way, the first information can implicitly indicate the target parameters corresponding to each set in multiple sets, the offset of LP-WUS and the number of sub-groups, and the correspondence between each set, without adding additional information to indicate the correspondence, which is conducive to saving the bits occupied by the first information and saving signaling overhead.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the first information includes a set identifier corresponding to each set in a plurality of sets, a target parameter corresponding to each set in the plurality of sets, an offset of the LP-WUS, and the number of subgroups, and the correspondence between each set is indicated by the set identifier corresponding to each set.

[0016] In this way, the first information can implicitly indicate the target parameters, LP-WUS offset and the number of sub-groups corresponding to each set in multiple sets, and the correspondence between each set can be explicitly indicated by the set identifier, which is conducive to improving the accuracy of the information obtained by the device receiving the information.

[0017] In conjunction with the first aspect, in certain implementations of the first aspect, the number of subgroups corresponding to each of the multiple sets is not exactly the same. The number of subgroups here may refer to the total number of subgroups in each set (subgroupsNumPerSET) and / or the total number of subgroups based on the identifier of the terminal device (UE_ID) (subgroupsNumForUEID).

[0018] In some implementations, a larger number of subgroupsNumPerSET may be configured for terminal device sets with a high paging frequency. For example, if SET 1 includes terminal devices with a high paging frequency, since the LP-WUS carries the SG ID of the terminal devices in the set, if UE 1 in SG 1 of SET 1 is frequently paged, the fewer UEs in the same subgroup as UE 1, the lower the probability that these UEs are mistakenly paged. Therefore, dividing the terminal devices in SET 1 into more subgroups to reduce the number of terminals in each subgroup helps reduce the probability of some terminal devices being mistakenly paged, and helps save signaling overhead and power consumption of these terminal devices.

[0019] In other implementations, a smaller subgroupsNumPerSET value can be configured for some of the multiple sets. This approach can reduce the number of bits occupied by the SG ID when the access network device sends an LP-WUS. For example, this set includes SET 2. If the total number of subgroups in SET 2 is 16, the SG ID can occupy a maximum of 4 bits to identify all subgroups, rather than the full 8 bits, which helps reduce signaling overhead and power consumption of the access network device.

[0020] In a second aspect, embodiments of the present application further provide a communication method that can be applied to a first terminal device or a chip in the first terminal device, but this application is not limited thereto. The method includes: receiving first information, the first information being used to indicate a target parameter corresponding to each set in a plurality of sets, and an offset and a number of subgroups of a low-power wake-up signal LP-WUS corresponding to each set in the plurality of sets, wherein the plurality of sets are sets divided for terminal devices monitoring the same paging occasion PO, and the target parameter is used to indicate the set to which the terminal device belongs based on its corresponding target parameter; monitoring the LP-WUS at a position corresponding to the first offset, and waking up a primary receiver upon receiving a first LP-WUS from the position corresponding to the first offset and the first LP-WUS including first subgroup information; wherein the first subgroup is a group in the set to which the first terminal device belongs, the first offset and the first subgroup information are determined based on the first target parameter corresponding to the first terminal device, according to the offset, target parameter, and number of subgroups of the low-power wake-up signal LP-WUS corresponding to each set in the plurality of sets, and the first target parameter is determined by the first terminal device or by a core network device.

[0059] The technical solution in this application will be described below with reference to the accompanying drawings.

[0060] In some embodiments provided herein, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the first and second numerical values are merely used to distinguish between different numerical values and do not limit their order. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or order of execution, and that terms such as "first" and "second" do not necessarily define differences.

[0061] It should be noted that in the embodiments of this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0062] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent the cases of existing A alone, existing A and B simultaneously, and existing B alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one (item)" or its similar expressions refer to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.

[0063] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th generation (5G) system or New Radio (NR), future evolved communication systems, such as 6th generation (6G) system, etc.

[0064] The terminal device in the embodiments of the present application can also be referred to as: User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), Access Terminal, User Unit, User Station, Mobile Station, Mobile Terminal, Remote Station, Remote Terminal, Mobile Device, User Terminal, Terminal, Wireless Communication Device, User Agent or User Device, etc.

[0065] The access network device and the core network device in the embodiments of the present application can be collectively referred to as network devices.

[0066] The core network device of the embodiment of the present application can be a core network device in a 4G system, such as a mobile management entity (MME), a serving gateway (sGW), etc., or a core network device in a 5G system, such as an access and mobility management function (AMF) network element, a user plane function (UPF) network element, etc. It can also be a core network device with other names, which is not limited in the embodiment of the present application.

[0067] The access network device can be any device with wireless transceiver capabilities. Access network equipment includes, but is not limited to, evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in a wireless fidelity (WiFi) system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc. It can also be a 5G base station (next-generation Node B, gNB) in a 5G, such as NR, system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or it can also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0068] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU may be responsible for processing non-real-time protocols and services, such as the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and / or the packet data convergence protocol (PDCP) layer. The DU may be responsible for processing physical layer protocols and real-time services. For example, it may implement the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. A DU can be connected to only one CU or to multiple CUs, and a CU can be connected to multiple DUs. Communication between the CU and DU can be achieved through the F1 interface. The AAU may implement some physical layer processing functions, RF processing, and active antenna related functions. Since the information of the RRC layer will eventually be delivered to the PHY layer and become the information of the PHY layer, or converted from the information of the PHY layer, therefore, in this architecture, high-layer signaling, such as RRC layer signaling, can also be considered to be sent by DU, or by DU+AAU.

[0069] It is understood that the access network device may include one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as an access network device in an access network (RAN) or as an access network device in a core network (CN), and this application does not limit this.

[0070] The access network equipment provides services for the cell. The terminal device communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the access network equipment. The cell can belong to a macro base station (for example, macro eNB or macro gNB, etc.) or a base station corresponding to a small cell. The small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0071] First, some technical terms involved in this application are introduced.

[0072] 1. Low Power Wake-Up Signal (LP-WUS)

[0073] It is a technology used in mobile communication networks to reduce the power consumption of terminal devices (such as smartphones and IoT devices). This technology sends a wake-up signal when the terminal device enters low-power mode, indicating whether the terminal device needs to wake up at a specific time to receive data or perform other tasks. This avoids the terminal device from continuously listening to network signals for unnecessary periods of time, thereby achieving energy conservation.

[0074] like Figure 1 As shown, the terminal device may include a main radio (MR) with relatively high power consumption and a low power wake-up receiver (LR) with relatively low power consumption. The main radio may be used to receive communication data such as paging messages; the low power wake-up receiver may be used to receive LP-WUS and wake up the main radio.

[0075] like Figure 2 As shown, the coverage of the LP-WUS transmitted by the access network device 201 is generally smaller than the coverage of the cell signal. When the terminal device 202 is within the coverage of the cell signal but not within the coverage of the LP-WUS, the terminal device 202 needs to monitor paging messages through the MR. When the terminal device 202 enters the coverage of the LP-WUS, the terminal device 202 stops monitoring paging messages through the MR and starts receiving the LP-WUS through the LR. When the LP-WUS related to itself is monitored, the MR is activated to further monitor paging messages from the network. Since the MR consumes a lot of power, this method helps save energy consumption of the terminal device.

[0076] Optionally, the main receiver may also be referred to as a main communication module, a main RF module, etc., and the low-power wake-up receiver may also be referred to as a low-power wake-up module, a low-power communication module, etc. This application does not make any specific limitations on this.

[0077] 2. Discontinuous reception (DRX)

[0078] LP-WUS typically works in conjunction with DRX. DRX allows end devices to enter a low-power sleep state when not receiving data, waking up to receive data when data is expected. LP-WUS builds on DRX by adding a wake-up signaling mechanism. When the network has data to send to the end device, it sends an LP-WUS in advance, notifying the end device to wake up and receive data during the next DRX activity cycle. If the network has no data to send, no LP-WUS is sent, and the end device remains in sleep mode, saving power.

[0079] It should be understood that the sleep state of the terminal device may be understood as a state in which the MR is turned off or in hibernation, and in this state the LR of the terminal device may be active.

[0080] A DRX cycle may include one or more paging radio frames (PF), and a paging radio frame may include multiple paging occasions (PO). When the core network device needs to page the terminal device, it will instruct the access network device to send the PDCCH at the PO associated with the terminal device. Therefore, when the terminal device monitors the paging at the PO, the terminal device can, for example, monitor the PDCCH scrambled by the paging radio network temporary identifier (P-RNTI) and decode it, and further receive the paging message at the time domain position indicated by the PDCCH.

[0081] Figure 1 A diagram illustrating the DRX cycle and LP-WUS transmission timing. When the core network device needs to page a terminal device, it instructs the access network device to send an LP-WUS before the DRX cycle to wake up the corresponding terminal device to listen to its corresponding PO.

[0082] Illustratively, the DRX cycle includes four PFs, namely, PF 1, PF 2, PF 3, and PF 4. Each of the four PFs includes PO 0 and PO 1. The UE can monitor PDCCH subframes on PO 0 and PO 1. The figure illustratively shows PO 0 and PO 1 corresponding to PF 1, and PO 0 and PO 1 corresponding to PF 2.

[0083] It should be understood that the terminal device and / or network device can calculate the position of the PF corresponding to the UE in each DRX cycle according to the following formula (1), and then further calculate the position of the PO corresponding to the UE in the PF according to formula (2).

[0084] Formula (1): (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N), where SFN is the system frame number to be calculated, T is the paging cycle, N is the number of PFs in a DRX cycle, PF_offset is the PF offset, and UE_ID is the result of 5G-S-TMSI mod 1024, where 5G-S-TMSI is the fifth generation system temporary mobile subscriber identity.

[0085] Formula (2): i_s=floor(UE_ID / N)mod Ns, where Ns is the number of POs configured under a PF, and i_s is the position index of the PO corresponding to the UE. The position here can be understood as the time domain position.

[0086] In the above formula, "mod" represents the remainder operation, for example, A mod B represents the remainder after dividing A and B; "div" represents integer division, which is the integer portion of the quotient (the integer part of the quotient) when dividing two integers. For example, 83 divided by 10 is 8 with a remainder of 3, and the result of 83 divided by 10 is 8; floor(x) represents rounding down, for example, floor(3.5) = 3; and "*" represents the multiplication operator. The same operators will not be explained again below.

[0087] It should be understood that LP-WUS and PO are associated, and it can also be understood that different POs correspond to LP-WUS transmitted by access network devices at different times. For example, PO 0 in PF 1 can be associated with LP-WUS 0; PO 1 in PF 1 can be associated with LP-WUS1, and so on.

[0088] It should also be understood that in order to facilitate the awakening of specific terminal devices through LP-WUS, the terminal devices monitoring the same PO can be divided into multiple sub-groupings (SG). In this way, the access network device can transmit the LP-WUS associated with the PO and carry the grouping information corresponding to the specific terminal device in the LP-WUS, such as the sub-grouping identity (SG ID), to wake up the terminal devices in the group where the specific terminal device is located.

[0089] Optionally, the terminal device and / or the network device may calculate the SGID of the terminal device using the following formula (3):

[0090] SG ID = (floor(UE_ID / (N*Ns))mod subgroupsNumForUEID) + (subgroupsNumPerPO – subgroupsNumForUEID), where UE_ID is the ID of the terminal device; N is the number of PFs included in a DRX cycle; Ns is the number of POs included under a PF; subgroupsNumForUEID is the total number of subgroups based on UE_ID; subgroupsNumPerPO is the total number of subgroups in each PO.

[0091] Next, take the core network device needing to wake up UE 4 as an example, combined with Figure 3 The example describes its wake-up process.

[0092] In the case that the core network device needs to wake up UE 4, the core network device instructs the access network device to send an LP-WUS associated with PO 0 and containing the SG ID corresponding to UE 4 before the next DRX cycle, for example Figure 3 As shown in FIG, the LP-WUS associated with PO 0 and including SG 129 is shown. Thus, among all the terminal devices corresponding to PO 0, the terminal devices included in the SG 129 group wake up their own MRs to monitor at the corresponding PO when they detect that the SG ID included in the LP-WUS is their own SG ID. For example, Figure 3 PO 0 included in PF 1 shown in FIG1 monitors the paging message from the core network device. Since the core network device actually needs to wake up UE 4, the terminal devices other than UE 4 included in the SG 129 group can continue to remain in the dormant state when the paging message they monitor contains a UE ID other than their own. However, when UE 4 monitors that the paging message contains its own UE ID, it can further initiate a random access procedure to access the network.

[0093] It should be understood that Figure 3 In the LP-WUS shown in FIG, 8 bits are used to indicate the SG ID, which can indicate 2 8 = 256 group indexes. It is worth noting that the group index indicated by these 8 bits is unique, that is, one LP-WUS can only wake up the terminal devices in one group corresponding to the PO.

[0094] It should be noted that, for a terminal device, based on the above formulas (1) to (3), the group to which the terminal device belongs can be uniquely determined within a DRX cycle, that is, the same terminal device will not be in two groups at the same time within a DRX cycle, that is, each terminal device has only one chance to be awakened within a DRX cycle, especially for terminal devices corresponding to the same PO, if multiple terminal devices to be awakened do not belong to the same group, it is necessary to continue to send LP-WUS associated with the PO before the subsequent multiple DRX cycles, and wake up the terminal devices in different groups associated with the PO one by one by carrying different SG IDs.

[0095] Still refer to Figure 3 If the core network device needs to wake up UE 4 and UE 7, the core network device can instruct the access network device to send an LP-WUS associated with PO 0 and containing the SG ID corresponding to UE 4 before the first DRX cycle to wake up UE 4, and send an LP-WUS associated with PO 0 and containing the SG ID corresponding to UE 7 after the first DRX cycle and before the next DRX cycle to wake up UE 7. In this way, the communication delay of UE 7 is likely to be longer.

[0096] To solve this technical problem, some possible discussions are to configure multiple offsets (offests) for LP-WUS and divide multiple terminal devices corresponding to the same PO into multiple sets (SETs). The access network device can send LP-WUS at different offset positions. Each LP-WUS can correspond to a SET and carry the subgroup number (SG ID) in the SET. In this way, terminal devices in different sets listening to the same PO can be woken up in one DRX cycle, that is, terminal devices in different groups listening to the same PO can be woken up, which is conducive to reducing communication latency.

[0097] like Figure 4As shown, UEs 1 to 18 monitoring the same PO belong to SET 1, UEs 7 to 12 belong to SET 12, and UEs 13 to 18 belong to SET 3. The UEs in SET 1 can be mapped to offset 1, the UEs in SET 2 to offset 2, and the UEs in SET 3 to offset 3. "Mapping the UEs in SET 1 to offset 1" can be understood as the UEs in SET 1 monitoring the LP-WUS at offset 1. That is, if the access network device sends LP-WUS 1 at offset 1, it can be monitored by the UEs in SET 1. Furthermore, if LP-WUS 1 contains the SG ID corresponding to the target UE, the UE corresponding to the SG ID in SET 1 can be woken up.

[0098] For example, if UE 1, UE 10, and UE 15 are to be woken up, the access network device may send LP-WUS1 carrying SG 1 at a location offset 1 from the PO location before a DRX cycle to wake up UE 1; send LP-WUS2 carrying SG 2 at a location offset 2 from the PO location to wake up UE 10; and send LP-WUS 3 carrying SG 1 at a location offset 3 from the PO location to wake up UE 15. This can reduce the communication delay of some of the UEs to be woken up.

[0099] However, if Figure 4 In the solution shown, it is extremely important to determine which SET the UE belongs to, that is, how the UE selects its monitoring location. However, the method for establishing the mapping relationship between the UE, SET, and offset has not yet been determined.

[0100] In view of this, the embodiments of the present application provide a communication method, a communication device, a chip system, a storage medium, and a program product. The access network device can broadcast a first message, and the first message is used to indicate the target parameters corresponding to each set in a plurality of sets, as well as the offset and number of subgroups of the LP-WUS corresponding to each set in a plurality of sets, wherein the plurality of sets are sets divided for terminal devices that monitor the same PO, and the target parameters are used to indicate that the terminal device determines the set to which it belongs based on its own corresponding target parameters. In this way, the terminal device can determine the set to which it belongs based on the target parameters corresponding to each set carried in the first message, as well as its own target parameters. Furthermore, it can also obtain the offset of the LP-WUS corresponding to the set, and can also calculate its own subgroup information in the set based on the number of subgroups corresponding to the set. Then, the terminal device can monitor the LP-WUS at the position corresponding to the offset of the LP-WUS. When the core network device needs to page the first terminal device, the core network device sends a second message to the access network device, where the second message includes a first target parameter corresponding to the first terminal device. In this way, the access network device can determine the set to which the first terminal device belongs based on this parameter and the information contained in the first message, obtain the offest of the LP-WUS corresponding to the first terminal device, and calculate the sub-group information of the first terminal device in the set based on the number of sub-groups corresponding to the set, and then send the LP-WUS containing the sub-group information of the first terminal device in the set at the offset. In this way, the first terminal device can monitor the LP-WUS at the offset of the LP-WUS calculated by itself, and when it is determined that the LP-WUS includes the sub-group information of itself in the set, it wakes up the main receiver to monitor the PO.

[0101] That is, the method provided in the embodiment of the present application can indicate the correspondence between the terminal device and the set (which can also be understood as the offset of the LP-WUS) through the first information determined by the access network device, which is beneficial for the access network device to determine at which offset to send the LP-WUS and for the terminal device to determine at which offset to receive the LP-WUS. In this way, by configuring multiple offests for the LP-WUS corresponding to the terminal device monitoring the same PO and sending LP-WUS at different offsets to wake up the terminal devices in different sets, the purpose of waking up the terminal devices that monitor the same PO and belong to different sets in one DRX cycle can be achieved, which is beneficial to reducing the communication delay of some terminal devices.

[0102] Next, the core network equipment, access network equipment and terminal equipment are the execution subjects, combined with Figure 5, the communication method provided by the embodiment of the present application is described in detail from the perspective of device interaction. The specific form and quantity of each device shown therein are only examples and should not constitute any limitation on the implementation of the method provided by the embodiment of the present application.

[0103] It should be understood that the terminal device can be the terminal device itself, or it can be a chip, chip system or processor that supports the terminal device to implement the signal transmission method, or it can be a logical module or software that can implement all or part of the terminal device; the access network device can be the access network device itself, or it can be a chip, chip system or processor that supports the access network device to implement the signal transmission method, or it can be a logical module or software that can implement all or part of the access network device; the core network device can be the core network device itself, or it can be a chip, chip system or processor that supports the core network device to implement the signal transmission method, or it can be a logical module or software that can implement all or part of the core network device. Please do not make specific limitations on this.

[0104] Figure 5 The schematic flow chart of a communication method 500 provided in an embodiment of the present application is exemplarily shown. The method 500 is applicable to a communication system including a first terminal device, an access network device and a core network device.

[0105] The method 500 includes the following steps:

[0106] S501. The access network device determines and sends the first information, where the first information is used to indicate the target parameters corresponding to each of the multiple sets, and the offset and the number of subgroups of the low-power wake-up signal LP-WUS corresponding to each of the multiple sets. The multiple sets are sets divided for terminal devices that monitor the same paging opportunity PO, and the target parameters are used to indicate that the terminal device determines the set to which it belongs based on its own corresponding target parameters; correspondingly, the first terminal device receives the first information.

[0107] It should be understood that the access network device can periodically broadcast the first information, and terminal devices in the idle state (RRC_IDLE), deactivated state (RRC_INACTIVE) and connected state (RRC_CONNECTED) can all receive the first information.

[0108] It is worth noting that the target parameters, LP-WUS offsets, and sub-group numbers (SGN) corresponding to each of the multiple sets included in the first information correspond to each set, that is, the first information also indicates to which of the multiple sets the multiple sets of target parameters, LP-WUS offsets, and sub-group numbers included therein belong. The target parameter included in the first information is used to indicate to the terminal device to determine the set to which it belongs based on its corresponding target parameter. Optionally, the target parameter in the first information can be a value or can indicate a range.

[0109] When the target parameter X included in the first information is a specific value, taking the first information including ((X1, offset1, SGN1)(X2, offset2, SGN2)(X3, offset3, SGN3)), and taking (X1, offset1, SGN1) corresponding to SET1, (X2, offset2, SGN2) corresponding to SET2, and (X3, offset3, SGN3) corresponding to SET3 as an example, the terminal device may determine the set to which it belongs based on its corresponding target parameter in the following manner: if the target parameter X of the terminal device is greater than or equal to zero and less than or equal to X1, the terminal device belongs to SET1; if the target parameter of the terminal device is greater than X1 and less than or equal to X2, the terminal device belongs to SET2; and if the target parameter of the terminal device is greater than X2 and less than or equal to X3, the terminal device belongs to SET3.

[0110] When the target parameter included in the first information indicates a range, taking the first information as including ((0-X1, offset 1, SGN 1)(X1-X2, offset 2, SGN 2)(X2-X3, offset 3, SGN 3)), and taking (0-X1, offset 1, SGN 1) corresponding to SET 1, (X1-X2, offset 2, SGN 2) corresponding to SET 2, and (X2-X3, offset 3, SGN 3) corresponding to SET 3 as an example, the terminal device may determine the set to which it belongs based on its corresponding target parameter in the following manner: if the target parameter X of the terminal device is greater than or equal to zero and less than or equal to X1, the terminal device belongs to SET 1; if the target parameter of the terminal device is greater than X1 and less than or equal to X2, the terminal device belongs to SET 2; and if the target parameter of the terminal device is greater than X2 and less than or equal to X3, the terminal device belongs to SET 3.

[0111] It is worth noting that in the embodiments of the present application, the endpoint values of each interval can be included in the previous interval or the next interval, and this application does not specifically limit this. For example, the target parameter X = X1 can be included in the range of 0 to X1 or in the range of X1 to X2. That is, a terminal device with a target parameter of X1 can belong to either SET 1 or SET 2. The target parameter X = X2 can be included in the range of X1 to X2 or in the range of X2 to X3. That is, a terminal device with a target parameter of X2 can belong to either SET 2 or SET 3. The same applies to other endpoint values and will not be further described. This application does not limit which adjacent set a terminal device belongs to when the target parameter is equal to the endpoint value of the set partition.

[0112] Optionally, the target parameters may include one or more of an effective paging rate, a false paging rate, a main receiver startup duration, or a main receiver startup power consumption. The effective paging rate may be understood as the ratio or percentage of the number of times a terminal device monitors the LP-WUS and a paging message related to itself at the PO to the number of times the terminal device monitors the LP-WUS; and the false paging rate may be understood as the ratio or percentage of the number of times a terminal device monitors the LP-WUS but does not monitor a paging message related to itself at the PO to the number of times the terminal device monitors the LP-WUS. False paging rate = 1 - effective paging rate.

[0113] It should be understood that the number of subgroups corresponding to each set in multiple sets includes the total number of subgroups in each set (subgroupsNumPerSET) and the total number of subgroups based on UE_ID (subgroupsNumForUEID). The access network device and / or the terminal device that receives the first information can calculate the subgroup information (SG ID) of the terminal device in the set to which it belongs based on the following formula (4).

[0114] Formula (4): SG ID = (floor(UE_ID / (N*Ns))mod subgroupsNumForUEID)+(subgroupsNumPerSET–subgroupsNumForUEID), where UE_ID is the ID of the terminal device; N is the number of PFs included in a DRX cycle; Ns is the number of POs included under a PF; subgroupsNumForUEID is the total number of subgroups based on UE_ID; and subgroupsNumPerSET is the total number of subgroups in each SET.

[0115] It should be noted that the offset of LP-WUS in the embodiment of the present application refers to the offset of LP-WUS relative to PO in the time domain, for example Figure 4 The offset 1, offset 2 and offset 3 shown in . The position of PO can be calculated according to the formula (1) and formula (2) shown above, which will not be repeated here.

[0116] S502. The core network device / first terminal device obtains the first target parameter.

[0117] In a first possible implementation, the first target parameter comes from the first terminal device, or is determined by the first terminal device. Specifically, a possible implementation of S502 includes: the first terminal device sends the first target parameter, and correspondingly, the core network device receives the first target parameter.

[0118] Optionally, the first target parameter may be sent by the first terminal device to the core network device during the registration process or after the registration is completed. For example, the first terminal device may send the effective paging rate and / or false paging rate of the first terminal device to the core network device during the registration process or after the registration is completed. This application does not limit this.

[0119] This situation can be understood as follows: after the first terminal device sends the first target parameter to the core network device, the core network device directly uses the first target parameter as the first terminal device's target parameter. Alternatively, the core network device agrees with the value reported by the first terminal device after negotiation, and therefore does not negotiate the result with the first terminal device. In this case, both the core network device and the first terminal device use the first target parameter as the first terminal device's final target parameter.

[0120] Optionally, the first target parameter may also be sent to the access network device during the process of establishing an RRC connection or after entering the RRC connection state. For example, data such as the main receiver startup duration and / or main receiver startup power consumption related to the capabilities of the first terminal device may be sent to the access network device during the process of establishing an RRC connection or after entering the RRC connection state. This application does not limit this.

[0121] It should be understood that if the first terminal device sends the first target parameter to the access network device during the process of establishing an RRC connection or after entering the RRC connection state, after receiving the first target parameter, the access network device sends the first target parameter to the core network device when the first terminal device is about to enter the idle state. Since the access network device will delete the RRC context related to the first terminal device after entering the idle state, the access network device sends the first target parameter to the core network device when the first terminal device is about to enter the idle state, so as to facilitate the core network device to page the first terminal device based on the first target parameter.

[0122] In a second possible implementation, the first target parameter is determined by the core network device based on the second target parameter reported by the terminal device. Specifically, a possible implementation of S502 includes: the first terminal device sends the second target parameter to the core network device, the second target parameter being determined by the first terminal device, and the core network device correspondingly receives the second target parameter; the core network device sends the first target parameter to the first terminal device, the first target parameter being obtained by the core network device based on the second target parameter.

[0123] In this case, it can be understood that after receiving the target parameter reported by the first terminal device, the core network device feeds back to the first terminal device the core network's negotiation result for the target parameter. The first target parameter and the second target parameter may be the same or different, and this application does not specifically limit this. It should be understood that the step of returning the negotiation result to the first terminal device after the core network device receives the target parameter reported by the first terminal device is optional.

[0124] When the RRC connection between the first terminal device and the access network device has been released (released) and the core network device needs to page the first terminal device, the core network device executes S503.

[0125] S503. The core network device determines and sends second information to the access network device. The second information is used to page the first terminal device. The second information includes the first target parameter. Correspondingly, the access network device receives the second information.

[0126] S504. The access network device sends a first LP-WUS. The first LP-WUS is sent at a position corresponding to the first offset. The first LP-WUS includes first sub-packet information. Correspondingly, the first terminal device receives the first LP-WUS.

[0127] It should be understood that the second information can be sent when the core network device needs to page the first terminal device. After receiving the second information, the access network device can determine the set to which the first terminal device belongs based on the first target parameter based on the method of determining the set to which the terminal device belongs based on the target parameter described above, and correspondingly obtain the first offset corresponding to the set.

[0128] It is worth noting that the second information may also include a UE ID list to be paged by the core network, which may include the UE ID of the first terminal device. Furthermore, the access network device may calculate the first subgroup information (e.g., SG ID) of the first terminal device in the set to which it belongs based on the above formula (4) and the number of first subgroups corresponding to the set to which the first terminal device belongs, and then send the first LP-WUS containing the first subgroup information at the position of the first offset.

[0129] S505: When the first terminal device determines that the first LP-WUS includes the first sub-group information, the first terminal device wakes up the main receiver.

[0130] In some implementations, after receiving the first information, the first terminal device may determine the set to which it belongs, and the corresponding LP-WUS monitoring position is the position corresponding to the first offset. Furthermore, based on the number of subgroups corresponding to the set to which it belongs and according to the above formula (4), the first terminal device may then monitor the LP-WUS at the position corresponding to the first offset. Upon monitoring the first LP-WUS from the first offset position and determining that the first LP-WUS contains the first subgroup information, the first terminal device may wake up the main receiver.

[0131] According to the method provided in the embodiment of the present application, the access network device can broadcast the first information, and the terminal device can determine the set corresponding to itself based on the target parameters corresponding to each set carried in the first information and its own target parameters. Furthermore, the offset of the LP-WUS corresponding to the set can be obtained, and the first sub-group information of itself in the set can be calculated based on the number of sub-groups corresponding to the set. In this way, the terminal device can determine the position corresponding to the offset at which it should listen to the LP-WUS. When the core network device needs to page the first terminal device, the core network device sends a second message to the access network device, where the second message includes a first target parameter corresponding to the first terminal device. In this way, the access network device can determine the set to which the first terminal device belongs based on this parameter and the information contained in the first message, obtain the first offset of the monitored LP-WUS corresponding to the first terminal device, and calculate the first sub-group information of the first terminal device in the set based on the number of sub-groups corresponding to the set, and then send the first LP-WUS containing the first sub-group information at the position of the first offset. In this way, the first terminal device can monitor the first LP-WUS at the first offset of the LP-WUS calculated by itself, and when it is determined that the first LP-WUS includes the first sub-group information, wake up the main receiver to monitor PO.

[0132] That is, the method provided in the embodiment of the present application can indicate the correspondence between the terminal device and the set (which can also be understood as the offset of the LP-WUS) through the first information determined by the access network device, which is beneficial for the access network device to determine at which offset to send the LP-WUS and for the terminal device to determine at which offset to receive the LP-WUS. In this way, by configuring multiple offsets (offests) for the LP-WUS corresponding to the terminal device monitoring the same PO, and sending LP-WUS at different offset positions to wake up the terminal devices in different sets, the purpose of waking up the terminal devices in different sets that monitor the same PO in one DRX cycle can be further achieved, so as to reduce the communication delay of some terminal devices.

[0133] Optionally, the number of subgroups corresponding to each set in the multiple sets may be the same or may not be completely the same, and this application does not make any specific limitation on this.

[0134] In one possible implementation, the number of subgroups corresponding to each set in multiple sets is not exactly the same. The number of subgroups here may refer to the total number of subgroups in each set (subgroupsNumPerSET) and / or the total number of subgroups based on UE_ID (subgroupsNumForUEID).

[0135] In some implementations, a larger number of subgroupsNumPerSET may be configured for terminal device sets with a high paging frequency. For example, if SET 1 includes terminal devices with a high paging frequency, since the LP-WUS carries the SG ID of the terminal devices in the set, if UE 1 in SG 1 of SET 1 is frequently paged, the fewer UEs in the same subgroup as UE 1, the lower the probability that these UEs are mistakenly paged. Therefore, dividing the terminal devices in SET 1 into more subgroups to reduce the number of terminals in each subgroup helps reduce the probability of some terminal devices being mistakenly paged, and helps save signaling overhead and power consumption of these terminal devices.

[0136] In other implementations, a smaller subgroupsNumPerSET value can be configured for some of the multiple sets. This approach can reduce the number of bits occupied by the SG ID when the access network device sends an LP-WUS. For example, this set includes SET 2. If the total number of subgroups in SET 2 is 16, the SG ID can occupy a maximum of 4 bits to identify all subgroups, rather than the full 8 bits, which helps reduce signaling overhead and power consumption of the access network device.

[0137] As an optional embodiment, the target parameters, LP-WUS offsets, and the number of subgroups corresponding to each of the multiple sets, and the corresponding relationship between each set are agreed upon by the protocol or indicated by a coding order.

[0138] Exemplarily, the number of multiple sets can be, for example, 3, and the first information can be exemplarily expressed as ((X 1, offset1, SGN 1)(X 2, offset 2, SGN 2)(X 3, offset 3, SGN 3)), where information related to a set, such as (X 1, offset 1, SGN 1) can be regarded as an element in the first information, and the correspondence between the element and the set is the target parameter, LP-WUS offset and the number of subgroups corresponding to each set in the multiple sets, and the correspondence between each set.

[0139] In some implementations, the correspondence between elements and sets can be implicitly indicated by the element encoding order or element index. For example, if the first information is encoded in the order of (X 1, offset 1, SGN 1) (X 2, offset 2, SGN 2) (X 3, offset 3, SGN 3), it can be understood that the first element (X 1, offset 1, SGN 1) corresponds to SET 1, the second element (X 2, offset 2, SGN 2) corresponds to SET 2, and the third element (X 3, offset 3, SGN 3) corresponds to SET 3. However, this application does not limit the specific order of the elements in the first information or the order of X, offset, and SGN in each element, and the number of sets mentioned above is only exemplary.

[0140] In other implementations, the correspondence between elements and sets can be agreed upon through a protocol. For example, the correspondence between the order of elements and sets can be specified through a protocol. For example, the element with the first element encoding order in the first information can be designated as corresponding to SET 2, the element with the second element encoding order in the first information can be designated as corresponding to SET 3, and the element with the third element encoding order in the first information can be designated as corresponding to SET 1. Optionally, the order of set identifiers (SET IDs) can be in ascending order, descending order, or any random order of the element encoding order, which is not specifically limited in this embodiment of the application.

[0141] As another optional embodiment, the first information also includes a set identifier corresponding to each of the multiple sets, a target parameter corresponding to each of the multiple sets, an offset of the LP-WUS, and the number of subgroups, and the correspondence between each set is indicated by the set identifier.

[0142] Still taking the example where the number of multiple sets may be 3, the first information may be exemplarily expressed as ((SET1: X1, offset 1, SGN1)(SET2: X2, offset 2, SGN2)(SET3: X3, offset 3, SGN3)), where (SET1: X1, offset 1, SGN1) may be considered as one element. In this case, each element includes a corresponding SET ID indicating its corresponding set. In this case, the encoding order of the elements in the first information may be arbitrary.

[0143] Combined with the above Figure 5 , describes in detail a communication method 500 provided by an embodiment of the present application. It can be seen that in the technical solution described in the method 500, the mapping relationship between the UE and the set can be understood as being configured by the access network device through the first information. Figure 6 Describe another communication method 600 provided in an embodiment of the present application. In method 600, the mapping relationship between the UE and the set can be indicated by a core network device. Method 600 can be applied to a communication system including a second terminal device, an access network device and a core network device.

[0144] Method 600 includes the following steps:

[0145] S601. The access network device determines and sends the fifth information, which includes the offset and the number of sub-groups of the low-power wake-up signal LP-WUS corresponding to each set in multiple sets. The multiple sets are sets divided for terminal devices that monitor the same paging opportunity PO; correspondingly, the second terminal device receives the fifth information.

[0146] S602. The second terminal device sends a third target parameter to the core network device. The third target parameter includes one or more of an effective paging rate, an incorrect paging rate, a main receiver startup duration, or a main receiver startup power consumption. Correspondingly, the core network device receives the third target parameter.

[0147] S603. The core network device sends third information to the second terminal device. The third information is used to indicate the first set to which the second terminal device belongs. The third information includes an identifier of the first set, and the identifier of the first set is determined based on a third target parameter. Correspondingly, the second terminal device receives the third information.

[0148] When the RRC connection between the second terminal device and the access network device has been released (released) and the core network device needs to page the second terminal device, the core network device executes S605.

[0149] S604. The core network device sends fourth information to the access network device. The fourth information is used to page the second terminal device. The fourth information includes an identifier of the first set. Correspondingly, the access network device receives the fourth information.

[0150] S605. The access network device sends a second LP-WUS. The second LP-WUS is sent at a position corresponding to a second offset. The second offset is the offset corresponding to the first set. The second LP-WUS includes second sub-group information. Correspondingly, the second terminal device receives the second LP-WUS.

[0151] S606: When the second terminal device determines that the second LP-WUS includes the second sub-group information, the second terminal device wakes up the main receiver.

[0152] It should be understood that in this embodiment, the offset of the LP-WUS and the number of subgroups corresponding to each of the multiple sets included in the fifth information also correspond to each set. The indication method of this correspondence can be similar to the indication method of the target parameters, the offset of the LP-WUS and the number of subgroups corresponding to each of the multiple sets included in the first information in the above method 500, and the correspondence between each set, and will not be repeated here.

[0153] In an embodiment of the present application, the core network device determines the first set to which the second terminal device belongs based on the third target parameter reported by the second terminal device, and indicates the identifier of the first set to the second terminal device. In this way, the second terminal device can determine the second offset and number of subgroups to which the second terminal device is monitoring based on the fifth information received from the access network device and the identifier of the first set to which the second terminal device belongs as indicated by the core network device, and further calculate the second subgroup information to which the second terminal device belongs based on the number of subgroups. If the core network device needs to page the second terminal device, the core network device can also include the identifier of the first set in the fourth information sent to the access network device for paging the second terminal device. In this way, the access network device can also determine the second offset and number of subgroups corresponding to the first set based on the fifth information and the identifier of the first set to which the second terminal device belongs as indicated by the core network device, and further calculate the second subgroup information to which the second terminal device belongs based on the number of subgroups. Specifically, the access network device can send a second LP-WUS carrying the second subgroup information at the position corresponding to the second offset to wake up the second terminal device. Correspondingly, upon determining that the second LP-WUS contains the second subgroup information, the second terminal device wakes up the primary receiver.

[0154] The method provided in the embodiment of the present application can indicate the correspondence between the terminal device and the set (which can also be understood as the offset of the LP-WUS) through the core network device, which is beneficial for the access network device to determine at which offset to send the LP-WUS and for the terminal device to determine at which offset to receive the LP-WUS. In this way, the purpose of waking up the terminal devices in different sets that monitor the same PO in one DRX cycle can be achieved by configuring multiple offsets (offests) for the LP-WUS corresponding to the terminal devices that monitor the same PO and sending LP-WUS at different offset positions to wake up the terminal devices in different sets, which is beneficial to reducing the communication delay of some terminal devices.

[0155] Optionally, in this embodiment, the way in which the core network device determines which set the second terminal device belongs to based on the third target parameter can be, for example, calculated through an artificial intelligence (AI) model, or it can be obtained based on the target parameter range assigned to each set as described in the above method 500. This application does not make any specific limitations on this.

[0156] It should be understood that the number of subgroups corresponding to each of the multiple sets included in the fifth information has a similar meaning to the number of subgroups corresponding to each of the multiple sets included in the above-mentioned first information, and will not be repeated here.

[0157] Optionally, the number of sub-groups corresponding to each of the multiple sets included in the fifth information may also be the same or different, and the configuration method and beneficial effects of the number are similar to the configuration method and beneficial effects of the number of sub-groups corresponding to each of the multiple sets included in the first information in the above method 500, and will not be repeated here.

[0158] It should also be understood that the sequence numbers of the above methods do not imply a specific order of execution; the execution order of each process should be determined by its functionality and internal logic. For example, the access network device may execute S601 for the first time no later than the time it executes S605. Furthermore, since the access network device can periodically execute S601, it is not necessary to execute S601 before each execution of S605. For another example, the core network device may execute S602 and S603 no later than the time it executes S604. However, based on this, there is no limitation on the timing of the access network device executing S601.
