Description

Communication methods and devices, terminal equipment and network equipment

[0001] This invention claims priority to the earlier application filed on July 12, 2024, entitled "Communication Method and Apparatus, Terminal Equipment and Network Equipment" (application number 2024109410467), the contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment and network equipment. Background Technology

[0003] To reduce the power consumption of terminal devices, the 3rd Generation Partnership Project (3GPP) has introduced the Low Power Wake-Up Signal (LP-WUS).

[0004] LP-WUS is a specially designed signal used to effectively wake up a terminal device when it is in an idle, sleep, standby, or powered-off state, so that the woken terminal device can receive data or perform other tasks when needed. Therefore, the design goal of LP-WUS is to minimize the power consumption of the terminal device while ensuring a high success rate of wake-up. Currently, how the terminal device determines the LP-WUS receiving resources is a problem that needs to be solved. Summary of the Invention

[0005] This application provides a communication method and apparatus, a terminal device and a network device, which are intended to enable LP-WUS transmission in one or more scenarios, such as multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up.

[0006] Firstly, a communication method according to this application includes:

[0007] Receive configuration information, which includes at least one of the following: the number of SSBs N, the number of LMOs corresponding to one SSB K, the number of subLOs contained in the LO G, the number of LP-WUS retransmissions R, or LP-WUS retransmission enable indication information; wherein, the LO contains N*K LMOs, where N is a positive integer, K is a positive integer, G is a positive integer, and Y is a positive integer;

[0008] According to the configuration information, LP-WUS is received on the first LMO, which is the LMO corresponding to the first SSB in the first sub-LO of the LO.

[0009] As can be seen, in scenarios where multi-beam operation is considered in the design of the LO, this application considers that one LO contains multiple LMOs corresponding to multiple SSBs. In scenarios of LP-WUS coverage enhancement, this application needs to adopt an LP-WUS retransmission mechanism to improve LP-WUS coverage. In scenarios of reducing the false alarm probability of terminal device wake-up, this application needs to increase the number of terminal device packets. Therefore, in one or more scenarios of multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up, in order to perform LP-WUS transmission, this embodiment designs one LO that can also contain one or more sub-LOs. The purpose of one LO containing multiple sub-LOs is to allow different sub-LOs to carry wake-up information of different terminal device packets, with one sub-LO corresponding to one terminal device packet, thereby reducing the false alarm probability of terminal device wake-up. In addition, the LMO corresponding to each SSB in a sub-LO can be used for LP-WUS retransmission, thereby realizing LP-WUS retransmission.

Terminal devices may include devices with wireless communication capabilities, such as chip systems, chips, or chip modules. For example, the chip system may include chips, and may also include other discrete devices. Terminal devices can be chips, chip modules, devices, units, etc., without specific limitations.

[0087] Network equipment

[0088] A network device is a device with transceiver capabilities that can be used to communicate with terminal devices.

[0089] Network devices may include means for providing wireless communication capabilities to terminal devices, such as chip systems, chips, or chip modules. For example, the chip system may include chips or other discrete devices. The network device provides services to a cell, and terminal devices within that cell can communicate with the network device through transmission resources (such as spectrum resources). This cell may be a macro cell, small cell, metro cell, micro cell, pico cell, or femto cell, etc.

[0090] In some possible examples, the network device has mobility characteristics; for example, the network device can be a mobile device. Optionally, the network device can be a satellite or a balloon station. For example, the satellite can be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary Earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device can also be a base station located on land, water, or other similar locations.

[0091] In some possible examples, network devices may include access network devices and / or devices in the core network (CN).

[0092] The access network equipment and core network equipment are described in detail below.

[0093] Access network equipment

[0094] Optionally, the access network equipment can be referred to as a radio access network (RAN) node. The RAN can be a network composed of multiple RAN nodes (e.g., 5G-RAN nodes), implementing radio physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions. The RAN can connect to the user plane function (UPF) via the user plane interface N3, and can be used to transmit data from terminal equipment; the RAN can establish a control plane signaling connection with the access and mobility management function (AMF) via the control plane interface N2, and is used to implement functions such as radio access bearer control.

[0096] Optionally, in 5G NR, the functionality of access network equipment is divided into two parts, known as centralized unit (CU) - distributed unit (DU) separation. From a protocol stack perspective, the CU includes the Radio Resource Control (RRC) layer and Packet Data Convergence Protocol (PDCP) layer of the LTE base station, while the DU includes the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical (PHY) layer of the LTE base station. In a typical 5G base station deployment, the CU and DU are physically connected via optical fiber and logically share a specially defined F1 interface for communication between them. Functionally, the CU is primarily responsible for radio resource control and configuration, inter-cell mobility management, and bearer management. The DU is primarily responsible for scheduling, physical signal generation, and transmission.

[0097] Optionally, the access network equipment can be macro base stations, micro base stations, pico base stations, small stations, relay stations, balloon stations, etc.

[0098] Core network equipment

[0099] Core network equipment may include network elements that provide various functions. The term "network element" can also be referred to as an entity, device, apparatus, or module, without specific limitation. Furthermore, for ease of understanding and explanation, the description of "network element" will be omitted in some descriptions. For example, a network exposure function (NEF) network element may be abbreviated as NEF. In this case, "NEF" should be understood as either a NEF network element or a NEF entity. The following will omit descriptions of similar cases.

[0100] For example, core network equipment may include a mobility management entity (MME), a broadcast multicast service center (BMSC), or corresponding functional entities in the 5G system, such as core network control plane (CP) or user plane (UP) network functions. The core network control plane can also be understood as the core network control plane function (CPF) entity.

[0102] It should be noted that terminal devices can connect to access network devices wirelessly, and access network devices can connect to core network devices wirelessly or via wired connections. Core network devices can connect to a data network (DN). Access network devices and core network devices can be independent physical devices, or the functions of core network devices and the logical functions of access network devices can be integrated into the same physical device. Alternatively, a single physical device can integrate some of the functions of core network devices and some of the functions of access network devices.

[0103] For example, Figure 2 is a schematic diagram of the architecture of another communication system according to an embodiment of this application. The names of the network elements included in Figure 2 are merely names and do not limit the function of the network elements themselves. In 5G networks and other future networks, the aforementioned network elements may also have other names, and no specific limitations are made. For example, in 6G networks, some or all of the aforementioned network elements may use the terminology from 5G, or they may have other names, etc. This will be uniformly explained here and will not be elaborated further below.

[0104] Furthermore, the various network elements in Figure 2 do not necessarily need to exist simultaneously; the required network elements can be determined based on needs. The connection relationships between the various network elements in Figure 2 are also not uniquely defined and can be adjusted according to requirements. It is understood that the aforementioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0105] Of course, Figure 2 is only an example of the network architecture of a communication system and does not constitute a limitation on the network architecture of the communication system in the embodiments of this application.

[0106] The communication system has been described above. The LP-WUS mechanism of this embodiment will be explained in detail below.

[0107] In the LP-WUS mechanism, terminal equipment may include a main radio (MR) and an LP-WUS receiver.

[0108] MR can be used for normal data communication. MR can have a complete RF and baseband processing architecture and can be viewed as a module / circuit for transmitting and receiving signals or channels other than LP-WUS. Of course, MR can also be called a main transceiver, overall transceiver, or regular transceiver, etc., without specific limitations.

[0109] An LP-WUS receiver can be used to receive LP-WUS signals. When a terminal device has no service or data scheduling, its MR (Mobile Receiver) can enter a sleep state to save energy. While the terminal device's MR is in sleep mode, when data scheduling or service occurs, the network device can send LP-WUS signals to the terminal device. The terminal device can then receive the LP-WUS signals through an LP-WUS receiver to wake it up. Of course, an LP-WUS receiver can also be called a low-power wake-up receiver or a low-power receiver.

[0110] To perform LP-WUS transmissions, network devices configure periodic LP-WUS occasions (LOs) for end devices. LO can be understood as the time-domain resource location where the LP-WUS transmission from the network device might occur, or the time-domain resource location where the end device is listening for LP-WUS transmissions. Additionally, the design of the LO may need to consider multi-beam scenarios.

[0111] In scenarios where a Locator (LO) is designed with multiple beams in mind, a single LO can include multiple LP-WUS monitoring occasions (LMOs), and each LMO corresponds to a different beam. A single beam can correspond to multiple LMOs, and different beams can correspond to different LMOs. Therefore, a single LO can contain multiple LMOs corresponding to multiple beams.

[0112] Furthermore, in multi-beam scenarios, beams can correspond to synchronization signal blocks (SSBs). For example, there is a one-to-one correspondence between beams and SSBs. In this case, multiple LMOs corresponding to multiple beams, one beam corresponding to multiple LMOs, and different beams corresponding to different LMOs can be viewed as multiple LMOs corresponding to multiple SSBs, one SSB corresponding to multiple LMOs, and different SSBs corresponding to different LMOs. In this case, one LO can contain multiple LMOs corresponding to multiple SSBs. The following embodiment mainly uses SSBs as an example for specific explanation. For the description of beams, this embodiment can replace SSBs with beams, and will not be repeated here.

[0113] However, for LP-WUS transmission, this embodiment may need to implement LP-WUS coverage enhancement. For example, this embodiment may employ an LP-WUS retransmission mechanism to improve LP-WUS coverage, thereby achieving LP-WUS coverage enhancement.

[0114] Additionally, for LP-WUS transmission, this embodiment may need to reduce the false alarm probability of terminal device wake-up. For example, this embodiment may increase the number of terminal device groups to reduce the false alarm probability of terminal device wake-up.

[0115] In summary, in order to perform LP-WUS transmission, this embodiment requires a new design for the LO in one or more scenarios such as multi-beam operation, LP-WUS coverage enhancement, or reduction of false alarm probability.

[0116] In a specific implementation, when a LO contains multiple LMOs, this embodiment can design a LO to also contain one or more sub-LOs.

[0117] In scenarios requiring enhanced LP-WUS coverage, the LMO corresponding to each SSB in a sub-LO can be used for repeated LP-WUS transmission, thereby enabling repeated LP-WUS transmission to improve LP-WUS coverage.

[0118] In scenarios aimed at reducing the false alarm probability of terminal device wake-up, a single LO (Location Allocation) can contain one or more sub-LOs, with each sub-LO corresponding to a terminal device group. Different sub-LOs can correspond to different terminal device groups. This allows different sub-LOs to carry wake-up information for different terminal device groups, thereby helping to reduce the false alarm probability of terminal device wake-up.

[0119] For example, originally one LO corresponds to 100 terminal devices, and these 100 terminal devices form a terminal device group. When the network device only needs to wake up one of these 100 terminal devices, since the LO corresponds to all 100 terminal devices, the network device will wake up all 100 terminal devices through the LO, resulting in a false alarm probability of 99 / 100. When the 100 terminal devices are divided into 5 terminal device groups, and each terminal device group includes 20 terminal devices, this embodiment designs the LO to contain 5 sub-LOs, with each sub-LO corresponding to one terminal device group. In this case, when the network device still only needs to wake up one of the 100 terminal devices, the network device only needs to wake up the 20 terminal devices in the terminal device group containing that one terminal device through one sub-LO, and the false alarm probability of terminal device wake-up is now 19 / 20. Thus, compared to the false alarm probability of 99 / 100, dividing one LO into multiple sub-LOs can reduce the false alarm probability of terminal device wake-up.

[0120] Based on this, as shown in Figure 3, which is a flowchart of a communication method according to an embodiment of this application, the method specifically includes the following steps:

[0121] S310. The network device sends configuration information, which includes at least one of the following: the number of SSBs N, the number of LMOs corresponding to one SSB K, the number of subLOs included in the LO G, the number of LP-WUS retransmissions R, or LP-WUS retransmission enable indication information.

[0122] Correspondingly, the terminal device receives this configuration information.

[0123] S320. The network device sends LP-WUS on the first LMO according to the configuration information. The first LMO is the LMO corresponding to the first SSB in the first sub-LO of the LO.

[0124] Here, the LO can be any LO. It can be understood that the first LMO is the LMO corresponding to the first SSB within the first sub-LO of any LO.

[0125] Correspondingly, the terminal device receives LP-WUS on the first LMO based on this configuration information.

[0126] As can be seen, in scenarios where multi-beam operation is considered in the design of the LO, this embodiment considers one LO to contain multiple LMOs corresponding to multiple SSBs. In scenarios of LP-WUS coverage enhancement, this embodiment needs to adopt an LP-WUS retransmission mechanism to improve LP-WUS coverage. In scenarios of reducing the false alarm probability of terminal device wake-up, this application needs to increase the number of terminal device packets. Therefore, in one or more scenarios of multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up, in order to perform LP-WUS transmission, this embodiment designs one LO to contain one or more sub-LOs. The purpose of one LO containing multiple sub-LOs is to allow different sub-LOs to carry wake-up information of different terminal device packets, with one sub-LO corresponding to one terminal device packet, thereby reducing the false alarm probability of terminal device wake-up. In addition, the LMO corresponding to each SSB in a sub-LO can be used for LP-WUS retransmission, thereby realizing LP-WUS retransmission.

[0127] Thus, this embodiment introduces configuration information, which includes at least one of the following: the number of SSBs N, the number of LMOs corresponding to one SSB K, the number of sub-LOs included in an LO G, the number of LP-WUS repeated transmissions R, or LP-WUS repeated transmission enable indication information. This configuration information enables LP-WUS transmission in one or more scenarios, such as multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up.

[0128] It should be noted that the terminal device can be in an idle state or an inactive state.

[0129] Furthermore, for a specific terminal device, the Loops (LOs) are periodic. The network device uses this configuration information to configure each LO in the periodic LOs of that terminal device in the same way. That is, each LO contains N*K LMOs, and each LO contains G sub-LOs, etc.

[0130] For any N*K LMOs in an LO, * represents multiplication, indicating that a multiplication operation is performed; N represents the number of SSBs, and N is a positive integer; K represents the number of LMOs corresponding to an SSB, and K is a positive integer.

[0131] For any LO containing N*K LMOs, these N*K LMOs have a temporal order. The first LMO in the LO refers to the earliest LMO in time, and the others follow in sequence. For example, with N=4 and K=3, as shown in Figure 4, the LO contains 12 LMOs, and these 12 LMOs have a temporal order.

[0132] Additionally, this configuration information can refer to one or more pieces of information sent by a network device. Different pieces of information can include different content. These one or more pieces of information can be carried by the same signaling (such as RRC signaling, MAC signaling, or downlink control information (DCI)), or they can be carried by different signaling.

[0133] The first LMO is the LMO corresponding to the first SSB within the first sub-LO of a periodic LO. This can be understood as the first LMO corresponding to the first SSB within the first sub-LO of any periodic LO. Each periodic LO has a first sub-LO, and each first sub-LO has an LMO corresponding to its first SSB. Therefore, the terminal device can listen for LP-WUS within the first LMO of each periodic LO based on this configuration information. When LP-WUS is detected, the terminal device can receive it.

[0134] It should be understood that since the first LMO is the LMO corresponding to the first SSB, the first LMO will also change when the first SSB changes.

[0135] The following embodiment will be described in detail from the following different embodiments.

[0136]

Example 1

[0137] In “Example 1”, the configuration information includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and the LP-WUS repetitive transmission enable indication. Additionally, the LO contains N*K LMOs.

[0138] It should be noted that the LP-WUS retransmission enable indication information can be used to indicate whether to enable or disable LP-WUS retransmission.

[0139] When LP-WUS retransmission is enabled, it means that LP-WUS retransmission needs to be performed. When LP-WUS retransmission is disabled, it means that LP-WUS retransmission is not performed.

[0140] In this way, the network configuration or network indication enables or disables LP-WUS repeat transmission by using LP-WUS repeat transmission enable indication information.

[0141] If the LP-WUS repetitive transmission enable indication information is used to indicate that LP-WUS repetitive transmission is enabled, then the K LMOs corresponding to one SSB are used to transmit or carry the same bit information, that is, LP-WUS performs K repetitive transmissions, which is equivalent to the number of LP-WUS repetitions being K. In this case, the LO in this embodiment is designed to include a sub-LO.

[0142] In other words, if the LP-WUS repetitive transmission enable indication information is used to indicate that LP-WUS repetitive transmission is enabled, then the LO contains a sub-LO. Alternatively, if K LMOs corresponding to an SSB are used to transmit or carry the same bit information, then the LO contains a sub-LO.

[0143] If the LP-WUS repetitive transmission enable indication information is used to indicate that LP-WUS repetitive transmission is disabled, then the K LMOs corresponding to one SSB are used to transmit or carry different bit information, that is, LP-WUS does not perform K repetitive transmissions, which is equivalent to the LP-WUS repetition count being 0. In this case, the LO in this embodiment is designed to contain K sub-LOs.

[0144] In other words, if the LP-WUS repetitive transmission enable indication information is used to indicate whether to enable LP-WUS repetitive transmission, then the LO contains K sub-LOs. Alternatively, if K LMOs corresponding to an SSB are used to transmit or carry different bit information, then the LO contains K sub-LOs.

[0145] As can be seen, in "Example 1", the LO in this embodiment is designed to include one or K sub-LOs. Each of the one or K sub-LOs needs to include an LMO.

[0146] The following embodiment will specifically explain how to determine the LMO of each sub-LO in one or K sub-LOs, with LP-WUS repetitive transmission enabled and LP-WUS repetitive transmission disabled.

[0147] Enable LP-WUS retransmission

[0148] When LP-WUS retransmission is enabled, the LO includes a sub-LO. In this case, the network device or terminal device of this embodiment can use the following mechanism to determine the LMO within the sub-LO.

[0149] Mechanism A

[0150] In "Mechanism A", the following two types can exist:

[0151] One type is the LMO corresponding to SSB i within a sub-LO, including the [x*N+i]th LMO within the LO; where i = 1, 2, ..., N; x = 0, 1, ..., K-1.

[0152] One type is the LMO corresponding to SSB j within a sub-LO, including the [(y-1)*N+j+1]th or [x*N+j+1]th LMO within the LO, where j = 0, 1, ..., N-1; y = 1, ..., K; x = y-1.

[0153] It should be noted that i and j here represent SSB indexes. Of course, the SSB index can be replaced with the SSB identifier (SSB ID) or SSB number. Where i = j + 1.

[0154] The formula i = 1, 2, ..., N means that the value of i starts from 1 and gradually increases until it ends at N, that is, i takes the values ​​1, 2, ..., N in sequence.

[0155] The formula x = 0, 1, ..., K-1 means that the value of x starts from 0 and gradually increases until it ends at K-1, that is, x takes the values ​​0, 1, ..., K-1 in sequence.

[0156] The formula j = 0, 1, ..., N-1 means that the value of j starts from 0 and gradually increases until it ends at N-1, that is, j takes the values ​​0, 1, ..., N-1 in sequence. The formula y = 1, ..., K means that the value of y starts from 1 and gradually increases until it ends at K, that is, y takes the values ​​1, ..., K in sequence.

[0157] For example, taking N as 4, K as 3, and the LMO corresponding to SSB j including the [x*N+j+1]th LMO in LO as an example, as shown in Figure 5, the LMO corresponding to SSB 0 is the 1st, 5th, and 9th LMO in LO, the LMO corresponding to SSB 1 is the 2nd, 6th, and 10th LMO in LO, the LMO corresponding to SSB 2 is the 3rd, 7th, and 11th LMO in LO, and the LMO corresponding to SSB 3 is the 4th, 8th, and 12th LMO in LO.

[0158] It can be seen that a sub-LO contains N*K LMOs, and that a sub-LO contains K LMOs corresponding to each of the N SSBs.

[0159] Mechanism B

[0160] In "Mechanism B", the following two types can exist:

[0161] One type is the LMO corresponding to SSB j within a sub-LO, including the [j*K+y]th LMO within the LO; where j = 0, 1, ..., N-1; y = 1, 2, ..., K.

[0162] One type is the LMO corresponding to SSB j within a sub-LO, including the [j*K+x+1]th LMO within the LO; where x = 0, 1, ..., K-1; x = y-1.

[0163] It should be noted that i and j represent SSB indices. Of course, the SSB index can be replaced with the SSB identifier or SSB number.

[0164] For example, taking N as 4, K as 3, and SSB j as the LMO including the [j*K+x+1]th LMO in LO, as shown in Figure 6, the LMO corresponding to SSB 0 is the 1st, 2nd, and 3rd LMO in LO; the LMO corresponding to SSB 1 is the 4th, 5th, and 6th LMO in LO; the LMO corresponding to SSB 2 is the 7th, 8th, and 9th LMO in LO; and the LMO corresponding to SSB 3 is the 10th, 11th, and 12th LMO in LO.

[0165] It can be seen that a sub-LO contains N*K LMOs, and that a sub-LO contains K LMOs corresponding to each of the N SSBs.

[0166] [Execute LP-WUS transfer]

[0167] In summary, when LP-WUS retransmission is enabled, the LO contains a sub-LO, which contains K LMOs corresponding to each of the N SSBs, and the LMOs within the sub-LO are determined according to mechanism A or mechanism B.

[0168] The following example illustrates how to perform LP-WUS transmission when LP-WUS retransmission is enabled.

[0169] In some possible examples, the process of a terminal device performing LP-WUS reception may include the following steps:

[0170] First, the terminal device can determine the first SSB among N SSBs. For example, the terminal device determines the first SSB among N SSBs based on the SSB measurement results. The SSB measurement results can reflect signal quality.

[0171] Optionally, the first SSB can be the SSB with the best signal quality among the N SSBs, or it can be an SSB with a signal quality greater than a preset threshold among the N SSBs. It should be understood that in the embodiments of this application, "equal to" can be used with "greater than" or "less than". When used with "greater than", it applies to the scheme corresponding to "greater than"; when used with "less than", it applies to the scheme corresponding to "less than".

[0172] Then, since a sub-LO contains K LMOs corresponding to each of the N SSBs, the terminal device can determine the LMO corresponding to the first SSB within that sub-LO. This sub-LO can be called the "first sub-LO," and the LMO corresponding to the first SSB can be called the "first LMO." The LMO corresponding to the first SSB (i.e., the first LMO) can be one, multiple, or all of the K LMOs corresponding to the first SSB.

[0173] Finally, the terminal device receives LP-WUS on the first LMO.

[0174] It should be noted that the network device will broadcast LP-WUS on the LMO (including the first LMO) corresponding to each of the N SSBs, while the terminal device will only listen to LP-WUS on the first LMO.

[0175] The process of performing LP-WUS transmission described above will be illustrated below based on Figure 3.

[0176] As shown in Figure 7, which is a flowchart illustrating another communication method according to an embodiment of this application, the method specifically includes the following steps:

[0177] S710. The network device sends configuration information, which includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and LP-WUS repetitive transmission enable indication information, which is used to indicate that LP-WUS repetitive transmission is enabled.

[0178] Correspondingly, the terminal device receives this configuration information.

[0179] S720. The terminal device determines the LMO within the first sub-LO in the LO based on the configuration information.

[0180] It should be understood that network devices can determine the LMO within the first sub-LO in this LO based on this configuration information.

[0181] Here, the LO can be any LO. It can be understood that network devices and terminal devices can determine the LMO within the first sub-LO of any LO based on this configuration information.

[0182] S730. The terminal device determines the first SSB among N SSBs.

[0183] S740. The network device sends LP-WUS on the first LMO, where the first LMO is the LMO corresponding to the first SSB within the first sub-LO.

[0184] Correspondingly, the terminal device receives the LP-WUS on the first LMO.

[0185] It should be noted that, for determining the first SSB among N SSBs, a specific implementation method can be: determining the first SSB among N SSBs based on SSB measurement results. The SSB measurement results can reflect signal quality. For example, the first SSB could be the SSB with the best signal quality among the N SSBs, or it could be an SSB whose signal quality is greater than a preset threshold among the N SSBs.

[0186] For determining the LMO within the first sub-LO based on the configuration information, a specific implementation could be: determining the LMO within the first sub-LO based on the configuration information and mechanism A, or determining the LMO within the first sub-LO based on the configuration information and mechanism B.

[0187] Thus, when the LMO within the first sub-LO is determined based on the configuration information and mechanism A, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [x*N+V]th LMO within the LO, or the LMO corresponding to the first SSB includes the [(y-1)*N+W+1]th LMO within the LO.

[0188] Where V represents the SSB index of the first SSB, V∈{1,2,…,N}. The formula V∈{1,2,…,N} means that V takes the value of one of {1,2,…,N}.

[0189] W represents the SSB index of the first SSB, W∈{0,1,…,N-1}. The formula W∈{0,1,…,N-1} means that W takes the value of one of {0,1,…,N-1}.

[0190] For example, taking Figure 5 as an example, when V is 1, the first LMO includes one or more LMOs among the 1st LMO, 5th LMO and 9th LMO in LO.

[0191] When the LMO within the first sub-LO is determined based on the configuration information and mechanism B, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [W*K+y]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [(V-1)*K+y]th or [(V-1)*K+x+1]th LMO within the LO. Here, V represents the SSB index of the first SSB, V∈{1,2,…,N}. W represents the SSB index of the first SSB, W∈{0,1,…,N-1}. For example, taking Figure 6 as an example, when the value of W is 0, the first LMO includes one or more LMOs from the 1st, 2nd, and 3rd LMOs within the LO.

[0192] Disable LP-WUS retransmission

[0193] When LP-WUS retransmission is disabled, the LO comprises K sub-LOs. In this case, the network device or terminal device of this embodiment can use the following mechanism to determine the LMO within each of the K sub-LOs.

[0194]

Mechanism a

[0195] In "mechanism a", the following two types can exist:

[0196] One type is the LMO corresponding to SSB i in subLO x among the K subLOs, including the [x*N+i]th LMO in the LO; where i = 1, 2, ..., N; x = 0, 1, ..., K-1.

[0197] One type is the LMO corresponding to SSB j in subLO x among the K subLOs, including the [x*N+j+1]th LMO in the LO; where j = 0, 1, ..., N-1.

[0198] It should be noted that i and j here represent the SSB index; x represents the sub-LO index. Of course, the sub-LO index can be replaced with the sub-LO identifier or sub-LO number.

[0199] For example, taking N as 4 (i.e., N=4), K as 3 (i.e., K=3), and the LMO corresponding to SSB j in sub-LO x including the [x*N+j+1]th LMO in LO as an example, as shown in Figure 8, the LMO corresponding to SSB 0 in sub-LO 0 is the 1st LMO in LO, the LMO corresponding to SSB 1 in sub-LO 0 is the 2nd LMO in LO, the LMO corresponding to SSB 2 in sub-LO 0 is the 3rd LMO in LO, and the LMO corresponding to SSB 3 in sub-LO 0 is the 4th LMO in LO.

[0200] The LMO corresponding to SSB 0 in sub-LO 1 is the 5th LMO in the LO, the LMO corresponding to SSB 1 in sub-LO 1 is the 6th LMO in the LO, the LMO corresponding to SSB 2 in sub-LO 1 is the 7th LMO in the LO, and the LMO corresponding to SSB 3 in sub-LO 1 is the 8th LMO in the LO.

[0201] The LMO corresponding to SSB 0 in sub-LO 2 is the 9th LMO in the LO, the LMO corresponding to SSB 1 in sub-LO 2 is the 10th LMO in the LO, the LMO corresponding to SSB 2 in sub-LO 2 is the 11th LMO in the LO, and the LMO corresponding to SSB 3 in sub-LO 2 is the 12th LMO in the LO.

[0202] In addition, the g-th LMO within sub-LO x is the [x*N+g]-th LMO within LO; where g = 1, 2, ..., N.

[0203] It can be seen that each of the K sub-LOs contains N LMOs, and each of the N SSBs in each sub-LO contains one LMO corresponding to each SSB.

[0204]

Mechanism b

[0205] In "mechanism b", the following two types can exist:

[0206] One type is the LMO corresponding to SSB j in the sub-LO y among the K sub-LOs, including the [j*K+y]th LMO in the LO; where j = 0, 1, ..., N-1; y = 1, 2, ..., K.

[0207] One type is the LMO corresponding to SSB j in subLO x among the K subLOs, including the [j*K+x+1]th LMO in the LO; where x=0,1,…,K-1.

[0208] It should be noted that i and j here represent the SSB index; x and y represent the sub-LO index. Of course, the sub-LO index can be replaced with the sub-LO identifier or sub-LO number.

[0209] For example, taking N as 4, K as 3, and the LMO corresponding to SSB j in sub-LO x including the [j*K+x+1]th LMO in LO as an example, as shown in Figure 9, the LMO corresponding to SSB 0 in sub-LO 0 is the 1st LMO in LO, the LMO corresponding to SSB 1 in sub-LO 0 is the 4th LMO in LO, the LMO corresponding to SSB 2 in sub-LO 0 is the 7th LMO in LO, and the LMO corresponding to SSB 3 in sub-LO 0 is the 10th LMO in LO.

[0210] The LMO corresponding to SSB 0 in sub-LO 1 is the 2nd LMO in the LO, the LMO corresponding to SSB 1 in sub-LO 1 is the 5th LMO in the LO, the LMO corresponding to SSB 2 in sub-LO 1 is the 8th LMO in the LO, and the LMO corresponding to SSB 3 in sub-LO 1 is the 11th LMO in the LO.

[0211] The LMO corresponding to SSB 0 in sub-LO 2 is the 3rd LMO in the LO, the LMO corresponding to SSB 1 in sub-LO 2 is the 6th LMO in the LO, the LMO corresponding to SSB 2 in sub-LO 2 is the 9th LMO in the LO, and the LMO corresponding to SSB 3 in sub-LO 2 is the 12th LMO in the LO.

[0212] It can be seen that each of the K sub-LOs contains N LMOs, and each of the N SSBs in each sub-LO contains one LMO corresponding to each SSB.

[0213] Perform LP-WUS transfer

[0214] In summary, when LP-WUS repetitive transmission is disabled, the LO contains K sub-LOs, each of which contains an LMO corresponding to each of the N SSBs, and the LMO within each sub-LO is determined according to mechanism a or mechanism b.

[0215] The following embodiment will specifically explain how to perform LP-WUS transmission when LP-WUS repetitive transmission is disabled.

[0216] In some possible examples, the process of a terminal device performing LP-WUS reception may include the following steps:

[0217] First, the terminal device can determine the first sub-LO from among the K sub-LOs. For example, the terminal device determines the first sub-LO from among the K sub-LOs based on the terminal device identifier and the value of K. The sub-LO index of the first sub-LO is determined by the terminal device identifier and the value of K.

[0218] Optionally, the sub-LO indices of the first sub-LO satisfy the following formula:

[0219] UE_ID mod K = Sub-LO index of the first sub-LO; where UE_ID represents the terminal device identifier, and mod represents the modulo operation; that is, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by K; or,

[0220] (UE_ID mod K) + 1 = Sub-LO index of the first sub-LO; that is, the sub-LO index of the first sub-LO is equal to the remainder of the terminal device identifier divided by K plus 1.

[0221] Secondly, the terminal device can determine the first SSB among N SSBs. For example, the terminal device determines the first SSB among N SSBs based on the SSB measurement results. The SSB measurement results can reflect signal quality. Optionally, the first SSB can be the SSB with the best signal quality among the N SSBs, or it can be an SSB with signal quality greater than a preset threshold among the N SSBs.

[0222] Then, since the first sub-LO contains one LMO corresponding to each of the N SSBs, the terminal device can determine the LMO corresponding to the first SSB in the first sub-LO. The LMO corresponding to the first SSB can be called the first LMO. The LMO corresponding to the first SSB (i.e., the first LMO) can be any LMO corresponding to the first SSB.

[0223] Finally, the terminal device receives LP-WUS on the first LMO.

[0224] It should be noted that the network device will broadcast LP-WU on the LMO (including the first LMO) corresponding to each of the N SSBs, while the terminal device will only listen to LP-WUS on the first LMO.

[0225] The process of performing LP-WUS transmission described above will be illustrated below based on Figure 3.

[0226] As shown in Figure 10, which is a flowchart illustrating another communication method according to an embodiment of this application, the method specifically includes the following steps:

[0227] S1010. The network device sends configuration information, which includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and LP-WUS repetitive transmission enable indication information; the LP-WUS repetitive transmission enable indication information is used to indicate whether LP-WUS repetitive transmission is enabled.

[0228] Correspondingly, the terminal device receives this configuration information.

[0229] S1020. The terminal device determines the LMOs within the K sub-LOs in the LO based on the configuration information.

[0230] It should be understood that network devices can determine the LMOs within the K sub-LOs in this LO based on this configuration information.

[0231] Here, the LO can be any LO. It can be understood that network devices and terminal devices can determine the LMOs within K sub-LOs of any LO based on the configuration information.

[0232] S1030. The terminal device determines the first sub-LO among the K sub-LOs.

[0233] It should be understood that the network device can determine the first sub-LO among the K sub-LOs.

[0234] S1040. The terminal device determines the first SSB among N SSBs.

[0235] S1050. The network device sends LP-WUS on the first LMO, where the first LMO is the LMO corresponding to the first SSB within the first sub-LO.

[0236] Correspondingly, the terminal device receives the LP-WUS on the first LMO.

[0237] It should be noted that, for determining the first SSB among N SSBs, a specific implementation method can be: determining the first SSB among N SSBs based on SSB measurement results. The SSB measurement results can reflect signal quality. For example, the first SSB could be the SSB with the best signal quality among the N SSBs, or it could be an SSB whose signal quality is greater than a preset threshold among the N SSBs.

[0238] To determine the first sub-LO among the K sub-LOs, a specific implementation method is to determine the first sub-LO among the K sub-LOs based on the terminal device identifier and the value of K. The sub-LO index of the first sub-LO is determined by the terminal device identifier and the value of K.

[0239] For determining the LMOs within the K sub-LOs based on the configuration information, a specific implementation could be: determining the LMOs within the K sub-LOs based on the configuration information and mechanism a, or determining the LMOs within the K sub-LOs based on the configuration information and mechanism b.

[0240] Thus, when the LMOs within the K sub-LOs are determined based on the configuration information and mechanism a, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [X*N+V]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [X*N+W+1]th LMO within the LO.

[0241] Where V represents the SSB index of the first SSB, V∈{1,2,…,N}; X represents the subLO index of the first subLO, X∈{0,1,…,K-1}; W represents the SSB index of the first SSB, W∈{0,1,…,N-1}.

[0242] For example, taking Figure 8 as an example, when V is 1 and X is 0, the first LMO includes the first LMO within LO.

[0243] Furthermore, the value of X can be determined by the terminal device identifier and the value of K. For example, X = UE_ID mod K. That is, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by the value of K.

[0244] When the LMOs within the K sub-LOs are determined based on the configuration information and mechanism b, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [W*K+Y]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [W*K+X+1]th LMO within the LO.

[0245] Where W represents the SSB index of the first SSB, W∈{0,1,…,N-1}; X and Y represent the subLO indices of the first subLO, X∈{0,1,…,K-1}, Y∈{1,2,…,K}.

[0246] For example, taking Figure 9 as an example, when the value of W is 0 and the value of Y is 1, the first LMO includes the first LMO within LO.

[0247] Additionally, the value of Y can be determined by the terminal device identifier and the value of K. For example, Y = (UE_ID mod K) + 1. That is, the sub-LO index of the first sub-LO is equal to the remainder of the terminal device identifier divided by the value of K plus 1.

[0248]

Example 2

[0249] In “Example 2”, the configuration information includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and the number of LP-WUS retransmissions R. Additionally, the LO contains N*K LMOs.

[0250] Thus, in this embodiment, the LO is designed to contain K / R sub-LOs. Here, / represents a division sign, performing a division operation; K is divisible by R. Each of these K / R sub-LOs needs to contain an LMO.

[0251] The network device or terminal device in this embodiment can use the following mechanism to determine the LMO of each sub-LO in the K / R sub-LOs, which will be described in detail below.

[0252] Mechanism 1

[0253] In "Mechanism One", the following two types can exist:

[0254] One type is the LMO corresponding to SSB i in sub-LO p among the K / R sub-LOs, including the [N*R*p+m*N+i]th LMO in the LO; where i=1,2,…,N; p=0,1,…,K / R-1; m=0,1,…,R-1.

[0255] One type is the LMO corresponding to SSB j in sub-LO p among the K / R sub-LOs, including the [N*R*p+(n-1)*N+j+1]th LMO in the LO; where j=0,1,…,N-1; n=1,2,…,R.

[0256] It should be noted that i and j here represent SSB indexes; m and n here represent the index of LP-WUP repetition count of SSB i; and p here represents the sub-LO index.

[0257] For example, taking N as 4 (N=4), K as 4 (K=4), R as 2 (i.e. R=2), and the LMO corresponding to SSB j in sub-LO p including the [N*R*p+(n-1)*N+j+1]th LMO in LO as an example, as shown in Figure 11, the LMO corresponding to SSB 0 in sub-LO 0 is the 1st and 5th LMO in LO, the LMO corresponding to SSB 1 in sub-LO 0 is the 2nd and 6th LMO in LO, the LMO corresponding to SSB 2 in sub-LO 0 is the 3rd and 7th LMO in LO, and the LMO corresponding to SSB 3 in sub-LO 0 is the 4th and 8th LMO in LO.

[0258] The LMOs corresponding to SSB 0 in sub-LO 1 are the 9th and 13th LMOs in the LO; the LMOs corresponding to SSB 1 in sub-LO 1 are the 10th and 14th LMOs in the LO; the LMOs corresponding to SSB 2 in sub-LO 1 are the 11th and 15th LMOs in the LO; and the LMOs corresponding to SSB 3 in sub-LO 1 are the 12th and 16th LMOs in the LO.

[0259] In addition, the s-th LMO within sub-LO p is the [N*R*p+s]-th LMO within LO; where s = 1, 2, ..., N*R.

[0260] It can be seen that each of the K / R sub-LOs contains N*R LMOs, and each sub-LO contains R LMOs corresponding to each of the N SSBs.

[0261] Mechanism Two

[0262] In "Mechanism 2", the LMO corresponding to SSB j in sub-LO p of the K / R sub-LOs includes the [N*R*p+R*j+n]th LMO in the LO; where j=0,1,…,N-1; p=0,1,…,K / R-1; n=1,2,…,R.

[0263] It should be noted that j here represents the SSB index; n here represents the index of the LP-WUP repetition count of SSB j; and p here represents the sub-LO index.

[0264] For example, taking N as 4 (N=4), K as 4 (K=4), and R as 2 (i.e., R=2) as an example, as shown in Figure 12, the LMO corresponding to SSB 0 in sub-LO 0 is the 1st and 2nd LMO in LO, the LMO corresponding to SSB 1 in sub-LO 0 is the 3rd and 4th LMO in LO, the LMO corresponding to SSB 2 in sub-LO 0 is the 5th and 6th LMO in LO, and the LMO corresponding to SSB 3 in sub-LO 0 is the 7th and 8th LMO in LO.

[0265] The LMO corresponding to SSB 0 in sub-LO 1 is the 9th and 10th LMO in the LO; the LMO corresponding to SSB 1 in sub-LO 1 is the 11th and 12th LMO in the LO; the LMO corresponding to SSB 2 in sub-LO 1 is the 13th and 14th LMO in the LO; and the LMO corresponding to SSB 3 in sub-LO 1 is the 15th and 16th LMO in the LO.

[0266] In addition, the s-th LMO within sub-LO p is the [N*R*p+s]-th LMO within LO; where s = 1, 2, ..., N*R.

[0267] It can be seen that each of the K / R sub-LOs contains N*R LMOs, and each sub-LO contains R LMOs corresponding to each of the N SSBs.

[0268] Mechanism Three

[0269] In "Mechanism Three", the following two types can exist:

[0270] One type is the LMO corresponding to SSB i in sub-LO p among the K / R sub-LOs, including the [N*(K / R)*m+p*N+i]th LMO in the LO; where i=1,2,…,N; p=0,1,…,K / R-1; m=0,1,…,R-1.

[0271] One approach is to define the LMO corresponding to SSB j within sub-LO p of the K / R sub-LOs, including the [N*(K / R)*(n-1)+p*N+j+1]th LMO within the LO; where j = 0, 1, ..., N-1; p = 0, 1, ..., K / R-1; n = 1, 2, ..., R. It should be noted that i and j represent SSB indices; m represents the index of the LP-WUP repetition count of SSB i; and p represents the sub-LO index.

[0272] For example, taking N as 4 (N=4), K as 4 (K=4), R as 2 (i.e. R=2), and the LMO corresponding to SSB j in sub-LO p including the [N*(K / R)*(n-1)+p*N+j+1]th LMO in LO as an example, as shown in Figure 13, the LMO corresponding to SSB 0 in sub-LO 0 is the 1st and 9th LMO in LO, the LMO corresponding to SSB 1 in sub-LO 0 is the 2nd and 10th LMO in LO, the LMO corresponding to SSB 2 in sub-LO 0 is the 3rd and 11th LMO in LO, and the LMO corresponding to SSB 3 in sub-LO 0 is the 4th and 12th LMO in LO.

[0273] The LMO corresponding to SSB 0 in sub-LO 1 is the 5th and 13th LMO in the LO; the LMO corresponding to SSB 1 in sub-LO 1 is the 6th and 14th LMO in the LO; the LMO corresponding to SSB 2 in sub-LO 1 is the 7th and 15th LMO in the LO; and the LMO corresponding to SSB 3 in sub-LO 1 is the 8th and 16th LMO in the LO.

[0274] It can be seen that each of the K / R sub-LOs contains N*R LMOs, and each sub-LO contains R LMOs corresponding to each of the N SSBs.

[0275] [Execute LP-WUS transfer]

[0276] In summary, in “Example 2”, the LO contains K / R sub-LOs, each of the K / R sub-LOs contains N*R LMOs, each sub-LO contains R LMOs corresponding to each of the N SSBs, and the LMOs in each sub-LO are determined according to mechanism one, mechanism two or mechanism three.

[0277] The following example illustrates how to perform LP-WUS transmission.

[0278] In some possible examples, the process of a terminal device performing LP-WUS reception may include the following steps:

[0279] First, the terminal device can determine the first sub-LO among the K / R sub-LOs. For example, the terminal device determines the first sub-LO among the K / R sub-LOs based on the terminal device identifier, the value of K, and the value of R. The sub-LO index of the first sub-LO is determined by the terminal device identifier, the value of K, and the value of R.

[0280] Optionally, the sub-LO indices of the first sub-LO satisfy the following formula:

[0281] UE_ID mod K / R = Sub-LO index of the first sub-LO. In other words, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by K / R.

[0282] Secondly, the terminal device can determine the first SSB among N SSBs. For example, the terminal device determines the first SSB among N SSBs based on the SSB measurement results. The SSB measurement results can reflect signal quality. Optionally, the first SSB can be the SSB with the best signal quality among the N SSBs, or it can be an SSB with signal quality greater than a preset threshold among the N SSBs.

[0283] Then, since the first sub-LO contains one LMO corresponding to each of the N SSBs, the terminal device can determine the LMO corresponding to the first SSB in the first sub-LO. The LMO corresponding to the first SSB can be called the first LMO. The LMO corresponding to the first SSB (i.e., the first LMO) can be one of the R LMOs corresponding to the first SSB, multiple LMOs, or all LMOs.

[0284] Finally, the terminal device receives LP-WUS on the first LMO.

[0285] It should be noted that the network device will broadcast LP-WU on the LMO (including the first LMO) corresponding to each of the N SSBs, while the terminal device will only listen to LP-WUS on the first LMO.

[0286] The process of performing LP-WUS transmission described above will be illustrated below based on Figure 3.

[0287] As shown in Figure 14, which is a flowchart illustrating another communication method according to an embodiment of this application, the method specifically includes the following steps:

[0288] S1410. The network device sends configuration information, which includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and the number of LP-WUS retransmissions R.

[0289] Correspondingly, the terminal device receives this configuration information.

[0290] S1420. The terminal device determines the LMOs within the K / R sub-LOs in the LO based on the configuration information.

[0291] It should be understood that network devices can determine the LMOs within the K / R sub-LOs in this LO based on this configuration information.

[0292] Here, the LO can be any LO. It can be understood that network devices and terminal devices can determine the LMOs within K / R sub-LOs of any LO based on the configuration information.

[0293] S1430. The terminal device determines the first sub-LO among the K / R sub-LOs.

[0294] It should be understood that the network device can determine the first sub-LO among the K / R sub-LOs.

[0295] S1440. The terminal device determines the first SSB among N SSBs.

[0296] S1450. The network device sends LP-WUS on the first LMO, where the first LMO is the LMO corresponding to the first SSB within the first sub-LO.

[0297] Correspondingly, the terminal device receives the LP-WUS on the first LMO.

[0298] It should be noted that, for determining the first SSB among N SSBs, a specific implementation method can be: determining the first SSB among N SSBs based on SSB measurement results. The SSB measurement results can reflect signal quality. For example, the first SSB could be the SSB with the best signal quality among the N SSBs, or it could be an SSB whose signal quality is greater than a preset threshold among the N SSBs.

[0299] To determine the first sub-LO among the K / R sub-LOs, a specific implementation method is as follows: determine the first sub-LO among the K / R sub-LOs based on the terminal device identifier, the value of K, and the value of R. The sub-LO index of the first sub-LO is determined by the terminal device identifier, the value of K, and the value of R.

[0300] For determining the LMO within the K / R sub-LOs based on the configuration information, a specific implementation can be: determining the LMO within the K / R sub-LOs based on the configuration information and mechanism one, or determining the LMO within the K / R sub-LOs based on the configuration information and mechanism two, or determining the LMO within the K / R sub-LOs based on the configuration information and mechanism three.

[0301] Thus, when the LMOs within the K / R sub-LOs are determined based on the configuration information and mechanism one, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*R*L+m*N+V]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*R*L+(n-1)*N+W+1]th LMO within the LO.

[0302] Where V represents the SSB index corresponding to the first SSB, V∈{1,2,…,N}; L represents the subLO index of the first subLO, L∈{0,1,…,K / R-1}; W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}. The s-th LMO in the first subLO is the [N*R*L+s]-th LMO in the LO.

[0303] For example, taking Figure 11 as an example, when V is 1 and L is 0, the first LMO includes one or more LMOs from the first LMO and the fifth LMO within LO.

[0304] When the LMOs within the K / R sub-LOs are determined based on the configuration information and mechanism two, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*R*L+R*W+n]th LMO within the LO. Here, W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}; L represents the sub-LO index corresponding to the first sub-LO, L∈{0,1,…,K / R-1}; n=1,…,R. The s-th LMO within the first sub-LO includes the [N*R*L+s]th LMO within the LO.

[0305] For example, taking Figure 12 as an example, when the value of W is 0 and the value of L is 0, the first LMO includes one or more LMOs from the first LMO and the second LMO within LO.

[0306] When the LMOs within the K / R sub-LOs are determined based on the configuration information and mechanism three, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*(K / R)*m+L*N+V]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*(K / R)*(n-1)+L*N+W+1]th LMO within the LO.

[0307] Where V represents the SSB index corresponding to the first SSB, V∈{1,2,…,N}; L represents the subLO index corresponding to the first subLO, L∈{0,1,…,K / R-1}; W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}.

[0308] For example, taking Figure 13 as an example, when V is 1 and L is 0, the first LMO includes one or more LMOs from the first LMO and the ninth LMO within LO.

[0309] In addition, the value of L can be determined by the terminal device identifier, the value of K, and the value of R. For example, L = UE_ID mod(K / R). That is, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by the value of K / R.

[0310]

Example 3

[0311] In “Example 3”, the configuration information includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and the number of sub-LOs contained in an LO G. In addition, an LO contains N*K LMOs.

[0312] Thus, in this embodiment, the LO is designed to contain G sub-LOs. Here, K is divisible by G; each of the G sub-LOs needs to contain an LMO.

[0313] The network device or terminal device in this embodiment can use the following mechanism to determine the LMO of each of the G sub-LOs, which will be described in detail below.

[0314] Mechanism 1

[0315] In "Mechanism 1", the following two types can exist:

[0316] One type is the LMO corresponding to SSB i in sub-LO q among the G sub-LOs, including the [N*(K / G)*q+v*N+i]th LMO in the LO; where i=1,2,…,N; q=0,1,…,G-1; v=0,1,…,(K / G)-1; / represents the division sign, performing the division operation.

[0317] One type is the LMO corresponding to SSB j in sub-LO q among the G sub-LOs, including the [N*(K / G)*q+(w-1)*N+j+1]th LMO in the LO; where j=0,1,…,N-1; q=0,1,…,G-1; w=1,2,…,K / G.

[0318] It should be noted that i and j here represent SSB indexes; v and w here represent the index of LP-WUP repetition count of SSB i; and q here represents the sub-LO index.

[0319] For example, taking N as 4 (N=4), K as 4 (K=4), and G as 2 (G=2) as an example, as shown in Figure 11.

[0320] Additionally, the t-th LMO within sub-LO q includes the [N*(K / G)*q+t]-th LMO within LO; where t = 1, 2, ..., N*(K / G).

[0321] It can be seen that each of the G sub-LOs contains N*(K / G) LMOs, and each sub-LO contains (K / G) LMOs corresponding to each of the N SSBs.

[0322] Mechanism 2

[0323] In "Mechanism 2", the LMO corresponding to SSB j in subLO q among the G subLOs includes the [N*(K / G)*q+(K / G)*j+w]th LMO in the LO; where j=0,1,…,N-1; q=0,1,…,G-1; w=1,2,…,K / G.

[0324] It should be noted that j here represents the SSB index; w here represents the index of the LP-WUP repetition count of SSB j; and q here represents the sub-LO index.

[0325] For example, taking N as 4 (N=4), K as 4 (K=4), and G as 2 (i.e. g=2) as an example, as shown in Figure 12.

[0326] Additionally, the t-th LMO within sub-LO q includes the [N*(K / G)*q+t]-th LMO within LO; where t = 1, 2, ..., N*(K / G).

[0327] It can be seen that each of the G sub-LOs contains N*(K / G) LMOs, and each sub-LO contains (K / G) LMOs corresponding to each of the N SSBs.

[0328] Mechanism 3

[0329] In "Mechanism 3", the following two possibilities exist:

[0330] One type is the LMO corresponding to SSB i in sub-LO q among the G sub-LOs, including the [N*G*v+q*N+i]th LMO in the LO; where i=1,2,…,N; q=0,1,…,G-1; v=0,1,…,(K / G)-1.

[0331] One type is the LMO corresponding to SSB j in sub-LO q among the G sub-LOs, including the [N*G*(w-1)+q*N+j+1]th LMO in the LO; where j=0,1,…,N-1; q=0,1,…,G-1; w=1,2,…,K / G.

[0332] It should be noted that i and j here represent SSB indexes; v and w here represent the index of LP-WUP repetition count of SSB i; and q here represents the sub-LO index.

[0333] For example, taking N as 4 (N=4), K as 4 (K=4), and G as 2 (G=2) as an example, as shown in Figure 13.

[0334] It can be seen that each of the G sub-LOs contains N*(K / G) LMOs, and each sub-LO contains (K / G) LMOs corresponding to each of the N SSBs.

[0335] [Execute LP-WUS transfer]

[0336] In summary, in “Example 3”, LO contains G sub-LOs, each of the G sub-LOs contains N*(K / G) LMOs, each sub-LO contains (K / G) LMOs corresponding to each SSB in N SSBs, and the LMOs in each sub-LO are determined according to mechanism 1, mechanism 2 or mechanism 3.

[0337] The following example illustrates how to perform LP-WUS transmission.

[0338] In some possible examples, the process of a terminal device performing LP-WUS reception may include the following steps:

[0339] First, the terminal device can determine the first sub-LO among the G sub-LOs. For example, the terminal device determines the first sub-LO among the G sub-LOs based on the terminal device identifier and the value of G. The sub-LO index of the first sub-LO is determined by the terminal device identifier and the value of G.

[0340] Optionally, the sub-LO indices of the first sub-LO satisfy the following formula:

[0341] UE_ID mod G = Sub-LO index of the first sub-LO. In other words, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by G.

[0342] Secondly, the terminal device can determine the first SSB among N SSBs. For example, the terminal device determines the first SSB among N SSBs based on the SSB measurement results. The SSB measurement results can reflect signal quality. Optionally, the first SSB can be the SSB with the best signal quality among the N SSBs, or it can be an SSB with signal quality greater than a preset threshold among the N SSBs.

[0343] Then, since the first sub-LO contains one LMO corresponding to each of the N SSBs, the terminal device can determine the LMO corresponding to the first SSB in the first sub-LO. The LMO corresponding to the first SSB can be called the first LMO. The LMO corresponding to the first SSB (i.e., the first LMO) can be one, multiple, or all of the K / G LMOs corresponding to the first SSB.

[0344] Finally, the terminal device receives LP-WUS on the first LMO.

[0345] It should be noted that the network device will broadcast LP-WU on the LMO (including the first LMO) corresponding to each of the N SSBs, while the terminal device will only listen to LP-WUS on the first LMO.

[0346] The process of performing LP-WUS transmission described above will be illustrated below based on Figure 3.

[0347] As shown in Figure 15, which is a flowchart illustrating another communication method according to an embodiment of this application, the method specifically includes the following steps:

[0348] S1510. The network device sends configuration information, which includes the number of SSBs N, the number of LMOs corresponding to one SSB K, and the number of subLOs contained in an LO G.

[0349] Correspondingly, the terminal device receives this configuration information.

[0350] S1520. The terminal device determines the LMOs within the G sub-LOs in the LO based on the configuration information.

[0351] It should be understood that network devices can determine the LMOs within the G sub-LOs in this LO based on this configuration information.

[0352] Here, the LO can be any LO. It can be understood that network devices and terminal devices can determine the LMOs within G sub-LOs of any LO based on the configuration information.

[0353] S1530. The terminal device determines the first sub-LO among the G sub-LOs.

[0354] It should be understood that the network device can determine the first sub-LO among the G sub-LOs.

[0355] S1540. The terminal device determines the first SSB among N SSBs.

[0356] S1550. The network device sends LP-WUS on the first LMO, where the first LMO is the LMO corresponding to the first SSB within the first sub-LO.

[0357] Correspondingly, the terminal device receives the LP-WUS on the first LMO.

[0358] It should be noted that, for determining the first SSB among N SSBs, a specific implementation method can be: determining the first SSB among N SSBs based on SSB measurement results. The SSB measurement results can reflect signal quality. For example, the first SSB could be the SSB with the best signal quality among the N SSBs, or it could be an SSB whose signal quality is greater than a preset threshold among the N SSBs.

[0359] To determine the first sub-LO among the G sub-LOs, a specific implementation method is to determine the first sub-LO among the G sub-LOs based on the terminal device identifier and the value of G. The sub-LO index of the first sub-LO is determined by the terminal device identifier and the value of G.

[0360] For determining the LMO within the G sub-LOs based on the configuration information, a specific implementation can be: determining the LMO within the G sub-LOs based on the configuration information and mechanism 1, or determining the LMO within the G sub-LOs based on the configuration information and mechanism 2, or determining the LMO within the G sub-LOs based on the configuration information and mechanism 3.

[0361] Thus, when the LMOs within the G sub-LOs are determined based on the configuration information and mechanism 1, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*(K / G)*S+v*N+V]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*(K / G)*S+(w-1)*N+W+1]th LMO within the LO.

[0362] Where V represents the SSB index corresponding to the first SSB, V∈{1,2,…,N}; S represents the subLO index of the first subLO, S∈{0,1,…,G-1}; W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}. The t-th LMO within the first subLO includes the [N*(K / G)*S+t]-th LMO within the LO, t=1,2,…,N*(K / G).

[0363] For example, taking Figure 11 as an example, when V is 1 and S is 0, the first LMO includes one or more LMOs from the first LMO and the fifth LMO within LO.

[0364] When the LMOs within the G sub-LOs are determined based on the configuration information and mechanism 2, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*(K / G)*S+(K / G)*W+w]th LMO within the LO; where W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}; and S represents the sub-LO index corresponding to the first sub-LO, S∈{0,1,…,G-1}. Furthermore, the t-th LMO within the first sub-LO includes the [N*(K / G)*S+t]-th LMO within the LO, where t=1,2,…,N*(K / G).

[0365] For example, taking Figure 12 as an example, when the value of W is 0 and the value of S is 0, the first LMO includes one or more LMOs from the first LMO and the second LMO within LO.

[0366] When the LMOs within the G sub-LOs are determined based on the configuration information and mechanism 3, the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*G*v+S*N+V]th LMO within the LO, or the LMO corresponding to the first SSB (i.e., the first LMO) includes the [N*G*(w-1)+S*N+W+1]th LMO within the LO.

[0367] Where V represents the SSB index corresponding to the first SSB, V∈{1,2,…,N}; S represents the subLO index corresponding to the first subLO, S∈{0,1,…,G-1}; W represents the SSB index corresponding to the first SSB, W∈{0,1,…,N-1}.

[0368] For example, taking Figure 13 as an example, when V is 1 and S is 0, the first LMO includes one or more LMOs from the first LMO and the ninth LMO within LO.

[0369] Furthermore, the value of S can be determined by the terminal device identifier and the value of G. For example, S = UE_ID mod G. That is, the sub-LO index of the first sub-LO is equal to the remainder when the terminal device identifier is divided by the value of G.

[0370] It should be noted that in the above embodiments of this application, the value of any one of the parameters i, j, y, w, v, x, p, m, n, q can start from 0, 1, or other values. Accordingly, the formula shown in the above embodiments is only an example. The above formula can also be modified according to the starting value of the relevant parameters. For example, based on the starting value of the index of the LP-WUP repetition count of SSB j, "[N*(K / G)*q+(w-1)*N+j+1]" in the above mechanism 1 can also be replaced with "[N*(K / G)*q+v*N+j+1]", where w = 1, 2, ..., K / G, that is, the starting value of the index of the LP-WUP repetition count of SSB j is 1, and v = 0, 1, ..., (K / G)-1, that is, the starting value of the index of the LP-WUP repetition count of SSB j is 0.

[0371] Furthermore, while the above embodiments use formula calculation to determine the LMO as an example, in actual implementation, the LMO can also be determined explicitly. When using an explicit method, the explicit information can be sent from the network device to the terminal device or specified by the protocol; this application does not impose any restrictions. For example, it can directly show which LMOs in the LO correspond to each SSB, or directly show the index of the LMO corresponding to each SSB. For example, in mechanism A above, based on the example shown in Figure 5, the LMO corresponding to each SSB is determined through Table 1. Table 1 can be specified by the protocol or sent by the network device to the terminal device; this application does not impose any restrictions.

[0470] According to the configuration information, LP-WUS is sent on the first LMO, which is the LMO corresponding to the first SSB in the first sub-LO of the LO.

[0471] As can be seen, in scenarios where multi-beam operation is considered in the design of the LO, this application considers that one LO contains multiple LMOs corresponding to multiple SSBs. In scenarios of LP-WUS coverage enhancement, this application needs to adopt an LP-WUS retransmission mechanism to improve LP-WUS coverage. In scenarios of reducing the false alarm probability of terminal device wake-up, this application needs to increase the number of terminal device packets. Therefore, in one or more scenarios of multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up, in order to perform LP-WUS transmission, this embodiment designs one LO that can also contain one or more sub-LOs. The purpose of one LO containing multiple sub-LOs is to allow different sub-LOs to carry wake-up information of different terminal device packets, with one sub-LO corresponding to one terminal device packet, thereby reducing the false alarm probability of terminal device wake-up. In addition, the LMO corresponding to each SSB in a sub-LO can be used for LP-WUS retransmission, thereby realizing LP-WUS retransmission.

[0472] Thus, this embodiment introduces configuration information, which includes at least one of the following: the number of SSBs N, the number of LMOs corresponding to one SSB K, the number of sub-LOs included in an LO G, the number of LP-WUS repeated transmissions R, or LP-WUS repeated transmission enable indication information. This configuration information enables LP-WUS transmission in one or more scenarios, such as multi-beam operation, LP-WUS coverage enhancement, or reducing the false alarm probability of terminal device wake-up.
