Description

Communication methods, terminal equipment and network equipment Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a communication method, terminal equipment, and network equipment. Background Technology

[0002] With the development of communication technology, terminal devices have increasingly higher requirements for energy efficiency. To address this, a low-power wake-up signal (LP-WUS) has been introduced. Terminal devices listen for the LP-WUS signal through a low-power wake-up receiver (LP-WUR). Upon receiving a wake-up signal from a network device, the LP-WUR wakes up the main receiver (MR). While the LP-WUR is listening for the LP-WUS signal, the MR can operate in a low-power state, thus achieving energy savings for the terminal device. To improve paging performance, the specific structure of the LP-WUS signal needs to be designed appropriately. Summary of the Invention

[0028] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0029] Communication system

[0030] Figure 1 is an example diagram of the system architecture of a communication system 100 to which embodiments of this application can be applied. The communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity; this embodiment of the application does not limit this.

[0031] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as: fifth generation (5G) systems, new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as sixth generation mobile communication systems, satellite communication systems, etc.

[0032] In this application embodiment, the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. Terminal devices can also be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes. Optionally, terminal devices can act as base stations. For example, a terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0033] In this embodiment, the network device can be a device used to communicate with a terminal device. The network device can be an access network device or a wireless access network device. For example, the network device can be a base station. The term "base station" can broadly encompass various names as follows, or can be replaced by names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master station (MeNB), secondary station (SeNB), multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar entity, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, or an entity that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or an entity that performs base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment. In some deployments, the network equipment may include a CU or a DU; or, the network equipment may include both a CU and a DU. Optionally, the base station may include an AAU.

[0034] Furthermore, base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0035] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0036] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0037] In the 3GPP R18 research project, LP-WUR was introduced to further save energy in terminal devices, and the LP-WUS signal was designed. LP-WUR listens for the LP-WUS signal, and when it receives a wake-up signal from a network device, LP-WUR wakes up the MR (Mobile Module). While using LP-WUR to listen for the wake-up signal, the MR can be in an extremely low-power state, namely ultra-deep sleep, thereby achieving overall energy savings for the terminal device.

[0038] LP-WUS / WUR

[0039] In Release 18 (R18), 3GPP studied LP-WUS / WUR and published research report TR 38.869. In 3GPP Release 19 (R19), LP-WUS / WUR was standardized, and the overall standardization content includes the following points:

[0040] 1. Standardize a general design for LP-WUS that can be applied to both the idle / inactive and connected states (RAN1, RAN4).

[0041] ● Standardized LP-WUS signals based on on-off keying (OOK) (e.g., OOK-1 and / or OOK-4) can be overlaid with OFDM sequences on the OOK symbols.

[0042] The design of LP-WUS should ensure that, in the IDLE / INACTIVE state, regardless of the receiver design used by LP-WUS, LP-WUS transmits the same information. Additionally, OFDM sequences can also carry information.

[0043] ●LP-WUS at least supports duty-cycled monitoring.

[0044] 2. For IDLE / INACTIVE states

[0045] ● Standardize the process and configuration for triggering LP-WUS paging message listening, including at least "Configuration", "Subgroup" and "Conditions for entering / exiting LP-WUS listening" (RAN2, RAN1, RAN3, RAN4).

[0046] ● The LP synchronization signal (LP-SS) with a standardization period of Y ms for LP-WUR can be used for synchronization of the serving cell and / or RRM (RAN1, RAN4).

[0047] LP-SS is based on OOK-1 and / or OOK-4 waveforms, and OFDM sequences can be superimposed on the OOK symbols with or without superimposing. In WI, the option to superimpose OFDM sequences on LP-SS is selected.

[0048] It should be noted that for LP-WURs that can receive existing primary synchronization signal (PSS) / secondary synchronization signal (SSS), the existing PSS / SSS signals can be used to replace LP-SS for synchronization and RRM.

[0049] The value of Y needs to be determined during the WI phase. For example, 320ms can be used as the initial value.

[0050] ● The measurement of the MR of the terminal equipment in the serving cell and neighboring cells is standardized by relaxing the RRM. The RRM measurement of the serving cell of the terminal equipment can be transferred from the MR to the LP-WUR for measurement, including the necessary condition design (RAN4, RAN2).

[0051] 3. For the CONNECTED state

[0052] ● The standardized LP-WUS triggering process for terminal equipment's MR to perform PDCCH monitoring includes the LP-WUS activation and deactivation processes (RAN2, RAN1).

[0053] 4. The coverage performance of LP-WUS and LP-SS is close to that of PUSCH message 3 (PUSCH msg3).

[0054] 5. The priority of LP-WUS signal optimization design in IDLE / INACTIVE state is higher than that in CONNECTED state.

[0055] During discussions at 3GPP standardization meetings, preliminary conclusions were reached regarding the signal design and type of wake-up information carried by LP-WUS, primarily including:

[0056] ●The maximum number of subgroups supported per paging occasion (PO) in Rel-19 is 31;

[0057] ●LP-WUS supports at least the following codepoints:

[0058] One code point corresponds to each of the multiple subgroups that can be indicated by LP-WUS;

[0059] One code point corresponds to all subgroups that can be indicated by LP-WUS; and,

[0060] Further discussion (FFS): Additional codepoints.

[0061] At the RAN1#120 meeting, it was proposed that in the IDLE / INACTIVE state, when the terminal device uses the LP-WUS correlation mechanism, the maximum number of subgroups that each PO can support is 31. At the RAN1#118bis meeting, a conclusion regarding code points was proposed: each LP-WUS indicator code point can correspond to one or more subgroups. Taking one PO corresponding to 31 subgroups as an example, 32 code points are needed to indicate the subgroups within that PO. Of these, 31 code points correspond one-to-one with each of the 31 subgroups, and the remaining code point is used to indicate that all 31 subgroups are awakened.

[0062] In addition, the following conclusions can be drawn regarding code points:

[0063] 1. RAN1#118 discusses support for the following subgroup information via LP-WUS indication for RRC idle / inactive states:

[0064] ●LP-WUS can indicate one or more subgroups from N subgroups using a single code point, and that code point is associated with some or all of the PO.

[0065] ● The terminal device needs to monitor one or more monitoring occasions (MOs) on the same beam within one LP-WUS occasion (LO) (maximum X MOs, X>1).

[0066] 2. The operating assumptions in RAN1#120 include that the terminal device that triggers the RRC connected state monitors the LP-WUS information of the PDCCH based on code points, wherein the terminal device checks a maximum of 8 code points per MO. Depending on the capabilities of the terminal device, some terminal devices may support fewer than 8 code points.

[0067] RAN1#120 discusses the mapping from LO to PO from the perspective of network devices, supporting terminal devices corresponding to different POs to monitor the same LO, specifically including:

[0068] ● The maximum number of code points supported by each LO / LP-WUS cannot be increased.

[0069] ●FFS: Specific conditions or restrictions that map multiple POs to a single LO.

[0070] ● The maximum number of POs corresponding to each LO needs to be selected between 2 and 4.

[0071] LP-WUS monitoring occasions (LP-WUS MO, MO)

[0072] The LP-WUS mechanism supports multi-beam processing, and each beam can be configured with K MOs. Optionally, if K > 1, the K MOs can be further divided into M groups of MOs, where each group consists of R MOs.

[0073] RAN1#118bis discusses the following options when configuring K (K>1) LP-WUS MOs for each beam within a single LO:

[0074] ●Option A: Divide the K LP-WUS MOs of one beam into M groups (M≥1), each group consisting of R LP-WUS MOs. The terminal equipment needs to monitor all or some of the MOs within the K LP-WUS MOs. The same LP-WUS information is transmitted in the R LP-WUS MOs of each group.

[0075] ●FFS: The transmission method of the same LP-WUS information in R LP-WUS MOs.

[0076] R LP-WUS MOs in different MO groups can transmit different LP-WUS information.

[0077] M = 1 and M > 1.

[0078] FFS: Specific monitoring behavior of terminal devices.

[0079] FFS: R = 1 or R ≥ 1.

[0080] ●Option B: The K LP-WUS MOs of one beam are divided into G (G≥1) groups, and each group includes R*M (M≥1) LP-WUS MOs. The terminal equipment monitors all or some of the MOs within the R*M LP-WUS MOs of a certain group according to its subgroup ID.

[0081] Each group, consisting of R*M LP-WUS MOs, is further divided into M subgroups, each containing R LP-WUS MOs.

[0082] ● The same LP-WUS information is transmitted in R LP-WUS MOs of each subgroup.

[0083] FFS: The transmission method of the same LP-WUS information in R LP-WUS MOs.

[0084] ● R LP-WUS MOs in different subgroups can transmit different LP-WUS information.

[0085] ●FFS: Specific monitoring behavior of terminal devices

[0086] Supports M=1 and M>1.

[0087] FFS: R = 1 or R ≥ 1.

[0088] It should be noted that the goal of this solution is equivalent to the goal of "the terminal devices monitoring the same PO are divided into multiple subgroups, and each subgroup corresponds to the same LO".

[0089] Protocol RAN1#119 discusses the 1:1 mapping relationship from LO to PO.

[0090] ● For option A or option B, when G=1, if either option A or option B is supported, the maximum value of parameter M is set to 4.

[0091] As an example, Figure 2 shows schematic diagrams of the two MO groupings for options A and B mentioned above. In Figure 2(a), beam 1 is associated with 8 MOs, and the 8 MOs are divided into 4 groups: group 1, group 2, group 3, and group 4. Group 1 includes MO1 and MO2, group 2 includes MO3 and MO4, group 3 includes MO5 and MO6, and group 4 includes MO7 and MO8. In Figure 2(b), beam 1 is associated with 8 MOs, and the 8 MOs are divided into 2 groups: group 1 and group 2. Both group 1 and group 2 are further divided into 2 subgroups. Group 1 includes group 1-1 and group 1-2, and group 2 is divided into group 21- and group 2-2. Group 1-1 includes MO1 and MO2, group 1-2 includes MO3 and MO4, group 2-1 includes MO5 and MO6, and group 2-2 includes MO7 and MO8.

[0092] As mentioned earlier, in the IDLE / INACTIVE state, one LP-WUS is used to indicate the value of a code point. This code point value is associated with a portion of a PO (i.e., a part of a PO), one PO, or N subgroups of multiple POs, and can correspond to one or more subgroups among the N subgroups. In the RAN1#120 meeting, the conclusion that one LO can be associated with multiple POs was supported, meaning that terminal devices listening to different POs can listen to the same LO.

[0093] In the CONNETED state, code points are also used to carry the wake-up message. However, considering that in the connected state, the network device should be able to wake up multiple terminal devices simultaneously, i.e., it can instruct multiple terminal devices at the same time. Therefore, each terminal device can be configured with multiple code points, and multiple terminal devices may have the same code points. The terminal device needs to check the received LP-WUS information using multiple code points. To account for the complexity of the terminal device, the maximum number of code points to be checked needs to be considered (e.g., no more than 8), and the maximum number of code points that can be checked can depend on the design of the terminal device.

[0094] Under the 3GPP LP-WUS / WUR project, we consider using code points to indicate wake-up information.

[0095] In IDLE / INACTIVE mode, it supports associating one code point with one subgroup, or one code point with all subgroups. It also supports wake-up indication of subgroups in multiple POs within the same LO. For example, as shown in Figure 3, the LO is associated with four POs: PO1, PO2, PO3, and PO4. This LO can be used to indicate wake-up of subgroups within PO1, PO2, PO3, and PO4. However, there is no solution for how to indicate subgroups in multiple POs using a single LO.

[0096] To address this, this application provides a design for an LP-WUS signal, wherein the LP-WUS includes a wake-up information indication field, and the indication field includes one or more fields, wherein the one or more fields are used to carry one or more code points, and the one or more code points are used to indicate one or more terminal devices to receive paging messages and / or listen to PDCCH. By using one or more code points carried on one or more fields in the LP-WUS, one or more terminal devices can be simultaneously indicated to receive paging messages and / or listen to PDCCH, thereby improving paging performance.

[0097] The embodiments of this application will be described in detail below with reference to Figure 4.

[0098] Figure 4 is a schematic flowchart of the communication method provided in an embodiment of this application. The method 400 shown in Figure 4 can be executed by a first terminal device and a network device. The first terminal device can be, for example, the terminal device 120 shown in Figure 1, and the network device can be, for example, the network device 110 shown in Figure 1.

[0099] Referring to Figure 4, in step 410, the network device sends LP-WUS to the first terminal device.

[0100] Accordingly, in step 420, the first terminal device receives the LP-WUS sent by the network device.

[0101] LP-WUS includes a wake-up information indication field, which includes one or more fields. These fields are used to carry one or more code points, and the code points are used to indicate that one or more terminal devices receive paging messages and / or listen to the PDCCH.

[0102] Optionally, the code point is used to wake up one subgroup in a PO; or, the code point is used to wake up all subgroups in a PO. For example, a PO corresponds to 31 subgroups. To indicate the wake-up of a subgroup in the PO, the code point corresponding to the PO has 32 possible values, for example, the code point consists of 5 bits. Among these 32 code points, 31 code points correspond one-to-one with the 31 subgroups in the PO, and the remaining code point is used to indicate the wake-up of all 31 subgroups.

[0103] When the first terminal device is in IDLE / INACTIVE state, after receiving the wake-up indication carried in the LP-WUS, it needs to listen to the corresponding PO and receive paging messages on the PO. For multiple subgroups listening to multiple POs, LP-WUS information located on the same LO can be listened to. Therefore, when the first terminal device receives the LP-WUS, it needs to be able to correctly obtain the wake-up information sent to itself, rather than using the wake-up information from other POs as its own wake-up information.

[0104] When the first terminal device is in the CONNETED state (or active state), after listening to the wake-up information carried in the LP-WUS, it needs to listen to the PDCCH. The first terminal device may be configured with multiple code points. In this case, the first terminal device needs to check the multiple configured code points in the LP-WUS information to determine whether there is a code point sent to it.

[0105] Whether in INACTIVE / IDLE or CONNETED state, LP-WUS may carry wake-up information from multiple terminal devices or multiple subgroups. This application provides the following solutions to enable the first terminal device to correctly obtain the wake-up information sent to it and / or obtain the listening instruction sent to it via PDCCH. Solutions 1 to 5 are for terminal devices in INACTIVE / IDLE state, and solution 6 is for terminal devices in CONNETED state.

[0106] For schemes 1 to 5, the wake-up message indication field of LP-WUS includes one or more fields. One or more code points carried on these fields can simultaneously instruct one or more terminal devices to receive paging messages. There is a correspondence between these one or more fields and the one or more POs associated with LP-WUS. This correspondence can be one-to-one, one-to-many, or many-to-one. For example, when LP-WUS is associated with one or more POs, the first field in the wake-up message indication field of LP-WUS corresponds to at least one of the one or more POs. The first field can be, for example, any of the one or more fields included in the wake-up message indication field of LP-WUS.

[0107] This application does not limit the number of one or more POs associated with the LP-WUS. For example, one LP-WUS can be associated with X POs, or one LO can be associated with X POs, where X can be, for example, 1, 2, 3 or 4.

[0108] Option 1

[0109] In some implementations, the correspondence between the first field in the indicator field of the wake-up message and at least one PO is determined based on the relative position of the first field among the multiple fields included in the indicator field of the wake-up message.

[0110] For example, as shown in Figure 5, the first terminal device receives an LP-WUS at the LO. This LP-WUS is associated with four POs, namely PO1, PO2, PO3, and PO4. The wake-up information indication field of the LP-WUS includes four corresponding fields: field 1, field 2, field 3, and field 4. Field 1 corresponds to PO1, field 2 to PO2, field 3 to PO3, and field 4 to PO4. Field 1 is used to wake up terminal devices in the subgroup corresponding to PO1, field 2 to PO2, field 3 to PO3, and field 4 to PO4.

[0111] Figure 5 illustrates a one-to-one correspondence between multiple fields in the wake-up message's indicator field and multiple Product Owners (POs). In other implementations, the relationship between these multiple fields and multiple POs can also be one-to-many or many-to-one. For example, the first field in the wake-up message's indicator field may be associated with at least two POs. Alternatively, the wake-up message's indicator field may also include a first field and a second field, both of which correspond to at least one PO; that is, the first field and the second field may correspond to the same PO.

[0112] For example, the number of fields included in the wake-up information indication field of LP-WUS is less than the number of POs associated with LP-WUS. Suppose the wake-up information indication field includes two fields, field 1 and field 2, and the number of POs associated with LP-WUS is four: PO1, PO2, PO3, and PO4. Field 1 is associated with PO1 and PO2, and field 2 is associated with PO3 and PO4.

[0113] For example, the number of fields included in the wake-up information indication field of LP-WUS is greater than the number of POs associated with LP-WUS. Suppose the wake-up information indication field includes four fields: field 1, field 2, field 3, and field 4, and the number of POs associated with LP-WUS is two: PO1 and PO2. Fields 1 and 2 are associated with PO1, and fields 3 and 4 are associated with PO2.

[0114] Optionally, if the first field and the second field in the wake-up indication field correspond to the same PO, the first terminal device can determine whether to listen to the first field or the second field based on the identification information of the first terminal device and / or the identification information of the subgroup to which the first terminal device belongs.

[0115] The following description uses the example of a one-to-one correspondence between multiple fields included in the wake-up information indication field and multiple POs to illustrate the technical solutions of the embodiments of this application.

[0116] In some implementations, the first terminal device may receive configuration information sent by the network device, which is used to configure one or more of the following: the length (e.g., number of bits) of the indication field of the wake-up message; the number of fields included in one or more fields of the indication message; and the length (e.g., number of bits) of each field in one or more fields of the indication message.

[0117] Assuming that the wake-up information indication field of LP-WUS includes N fields, and hereinafter, the number of fields included in the wake-up information indication field will also be denoted as N. or The length of the indicator field in the wake-up message is denoted as . The length of each field in the wake-up message's indicator field is denoted as . The value of N is, for example, equal to the number of POs associated with LP-WUS, or in other words, equal to the number of POs that receive wake-up instructions through LP-WUS, which is used to provide wake-up instructions for terminal devices within subgroups of its associated N POs.

[0118] The i-th field among the N fields corresponds to the i-th PO among the N POs associated with the LP-WUS, where i ranges from 1 to N. For example, if one LP-WUS is associated with two POs, then the LP-WUS includes two fields: the first field is used to indicate the wake-up of terminal devices in the subgroup of the first PO, and the second field is used to indicate the wake-up of terminal devices in the subgroup of the second PO.

[0119] Each of the N fields may include a code point, which is used to indicate the wake-up of terminal devices within a subgroup of the PO corresponding to that field. This code point can be used to indicate the wake-up of one subgroup within the PO, or to indicate the wake-up of all subgroups within the PO.

[0120] Optionally, the different fields included in the wake-up information indication field may carry different code point payloads, or the different fields may carry the same code point payload.

[0121] The wake-up information indication field of LP-WUS Each field can have the same payload, that is, the code points used to indicate wake-up to terminal devices within subgroups in different POs have the same payload, the size of which is, for example, the length of each field included in the wake-up information indication field mentioned above. in, Each of the fields corresponds to a PO.

[0122] At this point, the payload of the LP-WUS wake-up message, or in other words, the size of the indicator field of the wake-up message. It can be: The following specifies the length of the indicator field for the wake-up message. Length of each field And the number of fields included in the wake-up message indication information. The configuration method will be described in detail.

[0123] Method 1

[0124] The length of the indicator field in the network device configuration wake-up message and the number of POs associated with each LP-WUS The first terminal device according to and The payload size of the field used to indicate wake-up to terminal devices within a subgroup in the PO can be determined. That is, the length of each field.

[0125] Method 2

[0126] The length of the indicator field in the network device configuration wake-up message And the length of each field included in the wake-up message indication field. The first terminal device according to and The number of POs associated with each LP-WUS can be determined.

[0127] Method 3

[0128] Network device configuration: number of POs associated with each LP-WUS And the length of each field included in the wake-up message indication field. The first terminal device according to and The length of the indicator field in the wake-up message can be determined.

[0129] In methods 1 to 3 described above, where the indication field of the wake-up information corresponds one-to-one with multiple POs, the number of POs associated with each LP-WUS is... This refers to the number of fields included in the wake-up message's indicator field.

[0130] For example, each LP-WUS is associated with two POs, PO1 and PO2. The wake-up information indication field of LP-WUS includes two fields, Field 1 and Field 2. Field 1 is used to indicate the wake-up of the subgroup corresponding to PO1, and Field 2 is used to indicate the wake-up of the subgroups within PO2. Each PO in PO1 and PO2 corresponds to 31 subgroups. Therefore, if the length of each field in Field 1 and Field 2 is 5 bits (or the payload size of each code point), then 32 code points can be obtained. Taking PO1 and Field 1 as an example, 31 of the 32 code points carried by Field 1 correspond to the 31 subgroups in PO1 and are used to wake up the 31 subgroups within PO1. The remaining code point is used to wake up the terminal devices within all 31 subgroups in PO1. For example, when the code point value carried by field 1 is 00000, it is used to wake up all terminal devices in the 31 subgroups of PO1; when the code point value carried by field 1 is from 00001 to 11111, it is used to wake up the terminal devices in the 31 subgroups of PO1 individually. As another example, when the code point value carried by field 1 is 11111, it is used to wake up all terminal devices in the 31 subgroups of PO1; when the code point value carried by field 1 is from 00000 to 11110, it is used to wake up the terminal devices in the 31 subgroups of PO1 individually.

[0131] The first terminal device determines the field in LP-WUS associated with the PO corresponding to the first terminal device (or the PO corresponding to the subgroup to which the first terminal device belongs) based on the PO corresponding to the first terminal device (or the PO corresponding to the subgroup to which the first terminal device belongs), and determines whether to be woken up based on the code point of the field after receiving LP-WUS.

[0132] Option 2

[0133] In some implementations, LP-WUS also includes a third field. This third field is used to determine the correspondence between the first field and at least one PO. That is, LP-WUS includes a first field and a third field; the first field is used to carry code points, and the third field is used to indicate the PO associated with the LP-WUS.

[0134] For example, as shown in Figure 6, the wake-up information indication field of LP-WUS includes field 1 and field 2. Field 1 is used to indicate the PO associated with the LP-WUS, and field 2 carries a code point, which is used to wake up the terminal device in one or all of the multiple subgroups corresponding to the PO indicated by field 1.

[0135] Optionally, the length of the third field (e.g., the number of bits) is associated with the number of one or more POs associated with LP-WUS, or in other words, the length of the third field can be determined based on the number of one or more POs. For example, if the number of POs associated with LP-WUS is 1, the length of the third field is 0. As another example, if the number of POs associated with LP-WUS is 2, the length of the third field is 1; and as yet another example, if the number of POs associated with LP-WUS is 3 or 4, the length of the third field is 2.

[0136] For example, LP-WUS is associated with two POs, PO1 and PO2. LP-WUS includes a first field and a third field, where the third field can be 1 bit. When the third field is 0, it indicates that the first field is used to wake up terminal devices in one or all of the multiple subgroups corresponding to PO1; when the third field is 1, it indicates that the first field is used to wake up terminal devices in one or all of the multiple subgroups corresponding to PO2. Alternatively, when the third field is 1, it indicates that the first field is used to wake up terminal devices in one or all of the multiple subgroups corresponding to PO1; when the third field is 0, it indicates that the first field is used to wake up terminal devices in one or all of the multiple subgroups corresponding to PO2.

[0137] For example, if LP-WUS is associated with one PO, the third bit can be 1 bit, and the value of this bit is a predetermined value (e.g., 0 or 1); or, if LP-WUS is associated with one PO, the third bit may not be set in the indication field of the wake-up information of LP-WUS.

[0138] Alternatively, the length of the third field (e.g., number of bits) can be a fixed value associated with the maximum number of POs associated with LP-WUS. In other words, the length of the third field can be determined based on the maximum number of POs associated with LP-WUS. For example, if the number of POs associated with LP-WUS can be 1, 2, or 4, and the maximum number of POs associated with LP-WUS is 4, the length of the third field can be set to 2. Therefore, regardless of whether the number of POs associated with LP-WUS is configured as 1, 2, or 4, the length of the third field will always be 2.

[0139] As an example, 00 can represent the first PO, 01 the second PO, 10 the third PO, and 11 the fourth PO. When the number of POs associated with LKP-WUS is 1, the 2 bits of the third field are 00 to represent that PO; when the number of POs associated with LKP-WUS is 2, the 2 bits of the third field can be 00 and 01, corresponding to the first and second POs respectively; when the number of POs associated with LKP-WUS is 4, the 2 bits of the third field can be 00, 01, 10, and 11, corresponding to the first, second, third, and fourth POs respectively.

[0140] It is understandable that the LP-WUS described in Scheme 2 can give a wake-up instruction to the terminal device in the subgroup corresponding to one of the associated POs each time. If it is necessary to give a wake-up instruction to the terminal device in the subgroup corresponding to multiple POs, the network device can send multiple LP-WUS to the first terminal device to wake up the terminal devices in the subgroup corresponding to different POs respectively.

[0141] Option 3

[0142] In some implementations, LP-WUS includes multiple fourth fields. Each of these fourth fields includes a first field and a third field. It can be understood that Scheme 3 is equivalent to combining Schemes 1 and 2. Since LP-WUS, as described in Scheme 2, can only indicate the wake-up of terminal devices within a subgroup corresponding to one of its associated POs at a time, to simultaneously wake up terminal devices within subgroups corresponding to multiple POs via LP-WUS, multiple fourth fields can be set simultaneously in the indication field of the LP-WUS wake-up information, with each fourth field associated with a PO.

[0143] Taking LP-WUS, which includes two fourth fields, as an example, as shown in Figure 7, the wake-up information indication field of LP-WUS includes two sets of fields: a first set of fields and a second set of fields. Each set of fields includes field 1 and field 2. Field 1 is used to indicate the PO associated with the LP-WUS, and field 2 carries a code point. As shown in Figure 7, field 1 in the first set of fields is used to indicate PO1, and field 2 in the first set of fields is used to indicate the subgroup within PO1 that needs to be woken up; field 1 in the second set of fields is used to indicate PO2, and field 2 in the second set of fields is used to indicate the subgroup within PO2 that needs to be woken up.

[0144] The number of fourth fields included in the wake-up information indication field of LP-WUS is related to the number of POs corresponding to the terminal devices that need to be woken up simultaneously. For example, LP-WUS is associated with 4 POs. If the terminal devices in 2 of the POs need to be woken up simultaneously, the wake-up information indication field of LP-WUS includes 2 fourth fields; if the terminal devices in 3 of the POs need to be woken up simultaneously, the wake-up information indication field of LP-WUS includes 3 fourth fields; if the terminal devices in 4 of the POs need to be woken up simultaneously, the wake-up information indication field of LP-WUS includes 4 fourth fields; if only the terminal devices in 1 of the POs need to be woken up, the wake-up information indication field of LP-WUS includes 1 fourth field. In this case, LP-WUS is the same as LP-WUS in Scheme 2.

[0145] For details regarding the first and third fields included in the fourth paragraph of Scheme 3, please refer to the descriptions of the first and third fields in the aforementioned embodiments. For the sake of brevity, these details will not be repeated here.

[0146] Option 4

[0147] In some implementations, the wake-up information indication field of LP-WUS includes a first field, which includes a first code point associated with at least one PO.

[0148] Option 4 associates code points with POs. The indication field of the LP-WUS wake-up information includes one or more code points, which can have a corresponding relationship with one or more POs associated with the LP-WUS. This correspondence can be, for example, one-to-one, one-to-many, or many-to-one.

[0149] Optionally, the first code point may include first indication information. This first indication information is used to indicate at least one PO.

[0150] When an LP-WUS is associated with multiple POs, if the same code point value is used when assigning code points to each PO, the terminal devices corresponding to the multiple POs cannot determine which PO the LP-WUS is waking up for when listening to the LP-WUS; that is, they cannot determine whether the LP-WUS is waking up for themselves. By adding a field to the code point to indicate the PO, it can be clearly determined which PO the LP-WUS is waking up for.

[0151] As an example, as shown in Figure 8, the wake-up information indication field of LP-WUS consists of code points composed of field 1 and field 2. Field 1 is used to identify the PO, and field 2 is used to indicate the subgroup. Assuming that each PO corresponds to 31 subgroups, field 2 needs to include 5 bits, resulting in 32 code point values. 31 of these 32 code point values ​​are used to wake up the terminal devices in the 31 subgroups corresponding to the PO indicated by field 1, and the remaining code point value is used to wake up the terminal devices in all 31 subgroups corresponding to the PO indicated by field 1.

[0152] Optionally, the number of bits occupied by the first code point is associated with the number of one or more POs associated with LP-WUS; in other words, the number of bits occupied by the first code point can be determined based on the number of such one or more POs. The number of bits occupied by the first code point includes the number of bits occupied by the field of the first indication information (e.g., field 1 shown in Figure 8) and the number of bits occupied by the field in the first code point used to carry the code point value (e.g., field 2 shown in Figure 8). The number of bits occupied by the field used to carry the code point value is associated with the number of subgroups corresponding to each PO. The number of bits occupied by the first indication information is associated with the number of POs associated with LP-WUS.

[0153] For example, the number of bits occupied by the field carrying the code point value in the first code point (e.g., field 2 in Figure 8) is X. The value of X is associated with the number of subgroups corresponding to each PO. For example, if the number of subgroups corresponding to a PO is 31, then X = 5. When LP-WUS is associated with 1 PO, the number of bits in the first code point is X + Y, and Y = 0 or 1; when LP-WUS is associated with 2 POs, the number of bits in the first code point is X + Y, and Y = 1, wherein the added 1-bit field (e.g., field 1 shown in Figure 8) carries the first indication information; when LP-WUS is associated with 3 or 4 POs, the number of bits in the first code point is X + Y, and Y = 2, wherein the added 2-bit field (e.g., field 1 shown in Figure 8) carries the first indication information.

[0154] Alternatively, the length (e.g., number of bits) of the first indication information may be a fixed value associated with the maximum number of POs associated with LP-WUS. In other words, the length of the first indication information may be determined based on the maximum number of POs associated with LP-WUS. For example, if the number of POs associated with LP-WUS can be 1, 2, or 4, and the length of the first indication information is 2 based on the maximum number of POs associated with LP-WUS (4), then the length of the first indication information will be 2 regardless of whether the number of POs associated with LP-WUS is configured as 1, 2, or 4.

[0155] As an example, 00 can represent the first PO, 01 can represent the second PO, 10 can represent the third PO, and 11 can represent the fourth PO. When the number of POs associated with LKP-WUS is 1, the first two bits of the indication information are 00 to represent that PO; when the number of POs associated with LKP-WUS is 2, the first two bits of the indication information can be 00 and 01, corresponding to the first PO and the second PO, respectively; when the number of POs associated with LKP-WUS is 4, the first two bits of the indication information can be 00, 01, 10, and 11, corresponding to the first PO, the second PO, the third PO, and the fourth PO, respectively.

[0156] Alternatively, the first code point can be treated as a whole instead of being divided into different fields. For example, instead of dividing it into fields 1 and 2 as shown in Figure 8, the first code point can be treated as a whole, i.e., only the number of bits in the first code point is modified. In this case, the first code point can have at least X*Y different values, and the number of bits in the first code point is determined based on the value of X×Y. Here, X is determined based on the number of subgroups corresponding to each PO, and Y is determined based on the number of POs associated with LP-WUS. For example, when each PO is associated with 31 subgroups, X = 5; when LP-WUS is associated with 1 PO, Y = 0 or 1; when LP-WUS is associated with 2 POs, Y = 1; when LP-WUS is associated with 3 or 4 POs, Y = 2. Of course, in this method, there may be 1 bit that is the same among the values ​​of the first code point corresponding to different subgroups within the same PO.

[0157] It can be understood that X*Y represents the number of code points required to individually indicate different subgroups within a PO. Considering the case of wake-up indication for all subgroups, the first code point may include X*Y+1 code points, where the additional code point is used to indicate wake-up for all subgroups. Furthermore, when LP-WUS is associated with multiple POs, if each PO corresponds to one code point for indicating wake-up for all its subgroups, then the first code point may include X*Y+Z code points, where Z is the number of POs associated with LP-WUS.

[0158] For example, taking Figure 8 as an example, the wake-up information indication field of LP-WUS consists of code points composed of field 1 and field 2. Assuming LP-WUS is associated with two POs, PO1 and PO2, the first indication information in the first code point includes 1 bit. When this bit is 0, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO1; when this bit is 1, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO2. Alternatively, when this bit is 1, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO1; when this bit is 0, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO2. Whether field 2 indicates which subgroup or all of the multiple subgroups to wake up the terminal devices can be determined based on the code point value carried in field 2.

[0159] For example, taking Figure 8 as an example, the wake-up information indication field of LP-WUS consists of code points composed of field 1 and field 2. Assuming LP-WUS is associated with four POs, namely PO1, PO2, PO3, and PO4, the first indication information in the first code point includes 2 bits. Specifically, when this bit is 00, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO1; when this bit is 01, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO2; when this bit is 10, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO3; and when this bit is 11, field 2 is used to indicate the wake-up of terminal devices in one or all of the multiple subgroups in PO4. Whether field 2 indicates which subgroup or all of the multiple subgroups' terminal devices to wake up can be determined based on the code point value carried in field 2.

[0160] For example, if LP-WUS is associated with one PO, the first indication information can be 1 bit, and the value of this bit is a predetermined value (e.g., 0 or 1); or, if LP-WUS is associated with one PO, the first indication information may not be set in the code point of the indication field of the wake-up information of LP-WUS.

[0161] In other implementations, the first code point can be associated with a PO by restricting the code point characteristics corresponding to different POs. For example, if the first code point carried by the first field in the indication field of the LP-WUS wake-up information takes the first value, and the first value belongs to the code point value corresponding to at least one PO associated with the first field, then the code point values ​​corresponding to other POs (excluding the at least one PO) associated with LP-WUS should not include the first value.

[0162] For example, when LP-WUS is associated with multiple POs, the code point values ​​configured for subgroups within different POs are not the same. In other words, different POs associated with the same LP-WUS will not correspond to the same code point values.

[0163] Option 5

[0164] The LP-WUS mechanism supports multi-beam processing, and one or more MOs can be configured on each beam. When there are multiple POs associated with one LP-WUS, and multiple MOs are configured on each beam, in order to prevent terminal devices corresponding to different POs from being unable to distinguish which PO the LP-WUS indicates within the subgroup of terminal devices when listening to the LP-WUS of the same MO, an association between MO and PO can be established.

[0165] In some implementations, the LP-WUS is the LP-WUS transmitted in a first MO. This first MO is associated with at least one PO. That is, there is a correspondence between the multiple MOs beam-associated with the LP-WUS and the multiple POs associated with the LP-WUS. This correspondence can be, for example, one-to-one, one-to-many, or many-to-one.

[0166] The multiple MOs corresponding to each beam can be divided into multiple MO groups, for example, as shown in Figure 2. Assuming the first MO belongs to the first MO group among the M MO groups corresponding to the LP-WUS beam, then the first MO is associated with at least one PO, or in other words, the first MO group is associated with that at least one PO.

[0167] If the number of POs associated with LP-WUS is P, and P>1, then M MO groups can be configured for each beam. For example, the K MOs associated with the beam can be divided into M MO groups, and each MO group includes R MOs. Optionally, the M MO groups can be further divided into G groups, where each group includes one or more MO groups, and each MO group has R MOs. The relationship between P and M can satisfy M≥P.

[0168] Alternatively, the size relationship between P and M can be left unrestricted, thus combining it with the aforementioned schemes 1 to 4. For example, when M ≥ P, one PO may be associated with one or more MOs. In this case, it is not necessary to add a field to the LP-WUS in schemes 1 to 4 to distinguish between different POs. When M < P, multiple POs may be associated with the same MO. In this case, it is necessary to add a field to the LP-WUS in schemes 1 to 4 to distinguish between different POs.

[0169] In the case where the LP-WUS is transmitted in the first MO and the first MO is associated with at least one PO, the association between the first MO group and the at least one PO can be determined, for example, based on the number of MO groups corresponding to each beam (e.g., the value of M mentioned above) and / or the index of the at least one PO associated with the first MO.

[0170] For example, taking the division shown in Figure 2(a) as an example, LP-WUS beam 1 is associated with 8 MOs, and the 8 MOs are divided into 4 groups: group 1, group 2, group 3, and group 4. Group 1 includes MO1 and MO2, group 2 includes MO3 and MO4, group 3 includes MO5 and MO6, and group 4 includes MO7 and MO8. Assume that LP-WUS is associated with 4 POs: PO1, PO2, PO3, and PO4. Group 1 is associated with PO1, group 2 with PO2, group 3 with PO3, and group 4 with PO4. At this time, the terminal devices in the subgroup corresponding to PO1 listen for LP-WUS on the MOs (i.e., MO1 and MO2) in group 1; the terminal devices in the subgroup corresponding to PO2 listen for LP-WUS on the MOs (i.e., MO3 and MO4) in group 2; the terminal devices in the subgroup corresponding to PO3 listen for LP-WUS on the MOs (i.e., MO5 and MO6) in group 3; and the terminal devices in the subgroup corresponding to PO4 listen for LP-WUS on the MOs (i.e., MO7 and MO8) in group 4.

[0171] For example, taking the division method shown in Figure 2(b) as an example, LP-WUS beam 1 is associated with 8 MOs, and the 8 MOs are divided into 2 groups, namely group 1 and group 2. Both group 1 and group 2 are further divided into 2 subgroups. Group 1 includes group 1-1 and group 1-2, and group 2 is divided into group 21- and group 2-2. Among them, group 1-1 includes MO1 and MO2, group 1-2 includes MO3 and MO4, group 2-1 includes MO5 and MO6, and group 2-2 includes MO7 and MO8. Assume that LP-WUS is associated with 2 POs, namely PO1 and PO2. Among them, group 1 is associated with PO1, and group 2 is associated with PO2. At this time, the terminal devices in the subgroup corresponding to PO1 listen to the MO groups in group 1 (i.e., group 1-1 and group 1-2) via LP-WUS; the terminal devices in the subgroup corresponding to PO2 listen to the MO groups in group 2 (i.e., group 2-1 and group 2-2) via LP-WUS.

[0172] For example, LP-WUS beamlinks to 8 MOs, which are divided into 4 groups: Group 1, Group 2, Group 3, and Group 4. Assume LP-WUS is associated with 2 POs, PO1 and PO2. In this case, based on the PO index and the number of MO groups, it can be determined which MO group needs to be monitored. Specifically, terminal devices in the subgroup corresponding to PO1 monitor the MOs (or MO groups) in Group 1 and Group 2 using LP-WUS; terminal devices in the subgroup corresponding to PO2 monitor the MOs (or MO groups) in Group 3 and Group 4 using LP-WUS. Alternatively, terminal devices in the subgroup corresponding to PO1 monitor the MOs (or MO groups) in Group 1 and Group 3 using LP-WUS; terminal devices in the subgroup corresponding to PO2 monitor the MOs (or MO groups) in Group 2 and Group 4 using LP-WUS.

[0173] Option 6

[0174] Schemes 1 to 5 described above address the monitoring of LP-WUS by the first terminal device in the IDLE / INACTIVE state, enabling the first terminal device to correctly identify the wake-up information sent to it from the received LP-WUS. Scheme 6 addresses the monitoring of LP-WUS by the first terminal device in the CONNECTED state. Similar to Schemes 1 to 5, Scheme 6 can also design a multi-field LP-WUS to indicate multiple code points to the first terminal device. Furthermore, Scheme 6 provides a solution for how the first terminal device detects these multiple code points.

[0175] In some implementations, LP-WUS is LP-WUS for terminal devices in CONNECTED state. The wake-up information indication field of LP-WUS includes multiple fields. These multiple fields can be used to carry multiple code points, and these code points are used to indicate multiple terminal devices listening to the PDCCH. Each field can be used to carry one or more complete code points to indicate that the terminal device or group of terminal devices configured with that code point is listening to the PDCCH.

[0176] Specifically, since the terminal device in CONNECTED state needs to respond promptly to the dynamic commands of the network device, it needs to detect LP-WUS and find the corresponding PDCCH based on the code points in LP-WUS to obtain the DCI in that PDCCH. After receiving LR-WUS in MO, the terminal device can match the code points in L-PWUS with the pre-configured code point list. If the match is successful, it will receive the DCI on the corresponding PDCCH.

[0177] As an example, as shown in Figure 9, the first terminal device receives LP-WUS. The wake-up information indication field of LP-WUS includes four fields, namely field 1, field 2, field 3 and field 4. Assuming that the terminal device is configured with 8 code points, each of the fields 1, 2, 3 and 4 can carry 2 code points.

[0178] The first terminal device can determine how to perform code point checks within these multiple fields based on the following three methods.

[0179] Method 1

[0180] In some implementations, the number of code points that the first terminal device needs to check in each of the multiple fields is associated with the number of multiple fields and / or the number of code points configured in the first terminal device.

[0181] Considering that terminal devices in CONNECTED mode may have different capabilities, they support the inspection of different numbers of code points. For example, the maximum number of code points that a terminal device can support for inspection is 1, 2, 4, and 8. Among them, the first type of terminal device can only support configuring 1 code point, the second type of terminal device can support configuring up to 2 code points, the third type of terminal device can support configuring up to 4 code points, and the fourth type of terminal device can support configuring up to 8 code points.

[0182] The wake-up information indication field of LP-WUS includes N fields. The number of code points configured for the first terminal device is P. The first terminal device can determine the set of code points to be checked in each of the N fields based on the number of fields N included in the wake-up information indication field and the number of code points P configured.

[0183] For example, the index of the code point configured for the first terminal device is p. i The LP-WUS wake-up information indicator field consists of N fields, where i = 1, 2, ..., P. j Let j = 1, 2, ..., P. The index j of a field and the code points transmitted on that field satisfy the following relationship: j = p i mod N. Assume the first terminal device is configured with 8 code points, and the number of fields in the wake-up information indication field is N = 4. Then, the 1st and 5th code points are transmitted in the 1st field, and the first terminal device checks the 1st and 5th code points in the 1st field; the 2nd and 6th code points are transmitted in the 2nd field, and the first terminal device checks the 2nd and 6th code points in the 2nd field; the 3rd and 7th code points are transmitted in the 3rd field, and the first terminal device checks the 3rd and 7th code points in the 3rd field; the 4th and 8th code points are transmitted in the 4th field, and the first terminal device checks the 7th and 8th code points in the 4th field.

[0184] For example, the index of the code point configured for the first terminal device is p. i Let i = 1, 2, ..., P. The indexes for the N fields are n. j j = 1, 2, ..., P. The P code points can be grouped into groups of every P / N code points, and mapped to the ceil(p)-th code point. i In the N fields, where ceil is for upward verification. Assume the first terminal device is configured with 8 code points, and the wake-up information indication field includes N = 4 fields. Then, the 1st and 2nd code points are transmitted in the 1st field, and the first terminal device checks the 1st and 2nd code points in the 1st field; the 3rd and 4th code points are transmitted in the 2nd field, and the first terminal device checks the 3rd and 4th code points in the 2nd field; the 5th and 6th code points are transmitted in the 3rd field, and the first terminal device checks the 5th and 6th code points in the 3rd field; the 7th and 8th code points are transmitted in the 4th field, and the first terminal device checks the 7th and 8th code points in the 4th field.

[0185] Method 2

[0186] In some implementations, the wake-up information indication field of LP-WUS includes multiple fields, including a fifth field. This fifth field is the field from the multiple fields for which the first terminal device needs to perform code point checks, and it is associated with the identifier of the first terminal device and / or the number of the multiple fields. In other words, the first terminal device performs code point checks on a subset of these multiple fields.

[0187] The wake-up information indication field of LP-WUS includes N fields. The first terminal device can determine which field among the N fields to receive and check the code point based on the number N fields included in the wake-up information indication field and the identification ID of the first terminal device.

[0188] For example, the wake-up information indication field of LP-WUS includes N fields, and the index of these N fields is n. j Let j = 1, 2, ..., P. The index j of the field and the ID of the first terminal device satisfy the following relationship: j = ID mod N. Assume that the number of fields included in the wake-up information indication field is N = 4. Then, if the result of modulo N between the ID of the first terminal device and N is 1, the first terminal device checks the code point in the first field; if the result of modulo N between the ID of the first terminal device and N is 2, the first terminal device checks the code point in the second field; if the result of modulo N between the ID of the first terminal device and N is 3, the first terminal device checks the code point in the third field; if the result of modulo N between the ID of the first terminal device and N is 4, the first terminal device checks the code point in the fourth field.

[0190] In some implementations, the wake-up information indication field of LP-WUS includes multiple fields, and the first terminal device needs to perform code point checks on each of these multiple fields.
