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

[0110] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or a group of devices, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0111] In some embodiments, the above-mentioned one or more network elements may include, for example, AMF, UPF, MME, etc., and may also include other network elements, such as Policy Control Function (PCF), Application Function (AF), Network Application Function (NAF), Application Layer Authentication and Key Management Anchor Function (AAnF), Bootstrapping Server Functionality (BSF), Session Management Function (SMF), etc.

[0112] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0113] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0114] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0115] In the related art, the terminal can use a separate receiver LP-WUR to receive LP-WUS. The terminal needs to use the main radio (MR) or the main receiver (MR) when processing downlink and / or uplink data normally. The WUS signal may be used in RRC connected state (RRC connected), deactivated state (inactive), idle state (idle) and other states. The LP-WUS signal can instruct the terminal main radio to switch between any two sleep states, and can also instruct the terminal to wake up or not wake up. If the terminal receives a WUS signal indicating wakeup, the main radio will be turned on to receive and process downlink and / or uplink signals. If the WUS signal is not received, or the WUS indicates not to wake up, the terminal will maintain the current sleep state of the main radio. There are 4 types of MR sleep states: Ultra-deep sleep, Deep Sleep, Light Sleep, and Micro sleep.

[0116] LP-WUR operates in two modes: always on and duty cycle. In always on mode, the terminal's LP-WUR is always on, and the base station can send LP-WUS to wake the terminal at any time. In duty cycle mode, the terminal can, based on a certain mechanism, only turn on LP-WUR during the LP-WUS listening window, and the base station can only send LP-WUS to wake the terminal during this time period.

[0117] In related technologies, since LP WUR may generate time-frequency deviation during operation, low power synchronization signals (LP-SS) may be introduced to assist LP-WUS in performing time-frequency synchronization during reception.

[0118] There are two potential operating modes for LP-SS: per-cell configuration, where a cell is configured with only one common LP-SS, and all terminals synchronize their LP-WUS reception by receiving the LP-SS. Alternatively, LP-SS can be configured per UE or per UE group, where one LP-SS can be configured for each terminal or group. There are two potential LP-SS transmission modes: periodic and aperiodic.

[0119] The frequency domain bandwidth of the LP-WUS signal can be 5 MHz or 1.4 MHz, both of which are relatively narrow frequency domain bandwidths. Therefore, the LP-SS signal can use the same frequency domain bandwidth as the LP-WUS signal.

[0120] The BWP is designed for flexible resource scheduling and energy conservation. The frequency domain bandwidth of the LP-WUS signal is fixed, so the frequency domain resource configuration of the LP-WUS can be independent of the BWP configuration. The LP-WUR and the MR may operate on different frequency bands, so the MR's initial DL BWP may not be the WUR's initial DL BWP. The present invention can define the location of the frequency domain resources of the LP-WUS signal, that is, on which frequency domain resources the LP-WUS signal can be monitored. The present invention can also define a method for indicating the location of the frequency domain resources of the LP-WUS signal.

[0121] For the problem described in the above example, this solution proposes the following method.

[0122] Figure 2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The communication system 100 may include a terminal 101 and a network device 102. The method includes:

[0123] Step 2101a: The network device sends first information to the terminal.

[0124] In some embodiments, the first information may include at least one of the following:

[0125] System Information Block (SIB);

[0126] Radio Resource Control (RRC) signaling;

[0127] Media Access Control (MAC) signaling.

[0128] In some embodiments, the first information may carry the frequency domain resource size of the LP-WUS and the offset of the frequency domain resources of the LP-WUS relative to the frequency domain resources of the LP-SS, that is, the information carried by the first information can be used to determine the first frequency domain resources, and the first frequency domain resources can be used for the terminal to monitor the LP-WUS signal.

[0129] In some embodiments, the network device may indicate the first frequency domain resource information by sending the first information to the terminal, so as to facilitate determination of the frequency domain resource for the terminal to monitor the LP-WUS signal.

[0130] In some embodiments, the name of the first information may be "indication information", "judgment information", etc., but is not limited thereto. The present disclosure does not limit the specific name of the first information.

[0131] In some embodiments, the main receiver MR of the terminal may receive the first information.

[0132] In some embodiments, step 2101a is an optional step. When the network device and / or the terminal may not determine the first frequency domain resource based on the first information, the network device may not send the first information to the terminal.

[0133] Step 2102a: The network device and / or terminal determines a first frequency domain resource.

[0134] In some embodiments, the first frequency domain resource can be used for the terminal to monitor the low power wake-up signal LP-WUS, that is, the network device can send the LP-WUS signal on the first frequency domain resource, and the terminal can monitor the LP-WUS signal on the first frequency domain resource.

[0135] The method for the network device and / or the terminal to determine the first frequency domain resource may include at least one of the following:

[0136] In some embodiments, a first frequency domain resource may be determined based on the first information, where the first frequency domain resource is related to a frequency domain resource of a low power synchronization signal (LP-SS). That is, the first frequency domain resource may be determined based on a correlation between the first frequency domain resource and the LP-SS signal. In this case, the frequency domain resource of the LP-SS signal may be known, for example, the frequency domain resource of the LP-SS signal may be directly indicated by the network.

[0137] The methods described in Examples 1 to 3 below can determine the first frequency domain resource based on the frequency domain resource of the LP-SS signal when the LP-WUR and MR operate in the same or different frequency bands.

[0138] Example 1

[0139] Receive first information sent by a network device, where the first information carries a frequency domain resource size of the LP-WUS and an offset of the frequency domain resource of the LP-WUS relative to the frequency domain resource of the LP-SS. In this case, the first information may be a system information block (SIB), which is a new system information block (SIBX) independent of the existing SIB. In this case, the MR may be in an initial access state and may not be in a working state.

[0140] In some embodiments, the transmission time of SIBX needs to be later than that of SIB1, and the transmission time sequence with other existing SIBs is not restricted.

[0141] The offset is a resource block (RB) or a resource element (RE), and the subcarrier spacing of the offset is the subcarrier spacing when confirming the frequency domain position of the LP-SS.

[0142] In some embodiments, the above-mentioned subcarrier spacing is (Sub Carrier Space, SCS). Preferably, the subcarrier spacing of the offset can be indicated as the subcarrier spacing when confirming the frequency domain position of the LP-SS, which can reduce complexity; optionally, the subcarrier spacing of the offset can be different from the subcarrier spacing when confirming the frequency domain position of the LP-SS. In this case, the offset changes, and the subcarrier spacing of the offset needs to be additionally indicated.

[0143] Example 2

[0144] Receive first information sent by a network device, where the first information carries a frequency domain resource size of an LP-WUS and an offset of the frequency domain resources of the LP-WUS relative to the frequency domain resources of the LP-SS. The first information may be radio resource control (RRC) signaling or media access control (MAC) signaling, and the MR is in an active state.

[0145] The offset is a resource block (RB) or a resource element (RE), and the subcarrier spacing of the offset is the subcarrier spacing when confirming the frequency domain position of the LP-SS.

[0146] In some embodiments, the above-mentioned subcarrier spacing is (Sub Carrier Space, SCS). Preferably, the subcarrier spacing of the offset can be indicated as the subcarrier spacing when confirming the frequency domain position of the LP-SS, which can reduce complexity; optionally, the subcarrier spacing of the offset can be different from the subcarrier spacing when confirming the frequency domain position of the LP-SS. In this case, the offset changes, and the subcarrier spacing of the offset needs to be additionally indicated.

[0147] For example, the method may indicate information of the first frequency domain resource through the first information when instructing the MR to enter the sleep state. After the MR enters the sleep state, the auxiliary receiver (ie, LP-WUR) may determine the first frequency domain resource based on the first information.

[0148] For example, the method may not send the first information when instructing the MR to enter the sleep state, or may send the first information before instructing the MR to enter the sleep state, indicating the information of the first frequency domain resource. The terminal may store the first information. When the main receiver enters sleep, the auxiliary receiver may determine the first frequency domain resource based on the stored first information.

[0149] Example 3

[0150] Under the first condition, it is determined that the first frequency domain resource is the frequency domain resource of LP-SS, wherein the frequency domain resource size of LP-WUS is the frequency domain range of LP-SS, and / or the frequency domain resource position of LP-WUS is the frequency domain position of LP-SS, and the first condition is that the network device does not configure the first frequency domain resource for the terminal through the first information.

[0151] In other words, the network device may not configure the first frequency domain resources for the terminal through the first information. In this case, the relationship between the LP-WUS frequency domain resources and the LP-SS frequency domain resources may be determined based on the protocol predefined information. In this case, the location and size of the LP-SS frequency domain resources are known. Optionally, the size of the LP-SS frequency domain resources may be fixed, for example, 5 MHz or 1.4 MHz.

[0152] For example, the protocol predefines the frequency domain resource position of LP-WUS as the frequency domain position of LP-SS, and the frequency domain resource size of LP-WUS as the frequency domain range of LP-SS, that is, the frequency domain resource starting point of LP-WUS is the same as the frequency domain resource starting point of LP-SS, and the frequency domain resource size of LP-WUS is the same as the frequency domain resource size of LP-SS. At this time, the frequency domain resources of LP-WUS and LP-SS are the same, that is, the same block of frequency domain resources.

[0153] For another example, when the protocol predefines the frequency domain resource position of LP-WUS as the frequency domain position of LP-SS, the starting position of the frequency domain resources of LP-WUS can be determined according to the frequency domain position of LP-SS. At this time, the frequency domain resource size of LP-WUS can be larger than the frequency domain resource size of LP-SS, or smaller than the frequency domain resource size of LP-SS.

[0154] FIG2b is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2b , the present disclosure embodiment relates to a communication method for use in a communication system 100 , which may include a terminal 101 and a network device 102 . The method includes:

[0155] Step 2101b: The network device sends a first signaling to the terminal.

[0156] In some embodiments, the first signaling may carry the frequency domain position of the LP-WUS, and the first signaling may be used to determine the frequency domain position of the LP-WUS, which may facilitate determination of the first frequency domain resource based on the first signaling.

[0157] In some embodiments, the network device may indicate the first frequency domain resource information by sending a first signaling to the terminal, so as to facilitate determination of the frequency domain resource for the terminal to monitor the LP-WUS signal.

[0158] In some embodiments, the name of the first signaling may be "indication signaling", "judgment signaling", etc., but is not limited thereto. The present disclosure does not limit the specific name of the first signaling.

[0159] In some embodiments, the primary receiver MR of the terminal may receive the first signaling.

[0160] In some embodiments, step 2101b is an optional step. When the network device and / or the terminal may not determine the first frequency domain resource based on the first signaling, the network device may not send the first signaling to the terminal.

[0161] Step 2102b: The network device and / or terminal determines a first frequency domain resource.

[0162] In some embodiments, the first frequency domain resource can be used for the terminal to monitor the low power wake-up signal LP-WUS, that is, the network device can send the LP-WUS signal on the first frequency domain resource, and the terminal can monitor the LP-WUS signal on the first frequency domain resource.

[0163] The method for the network device and / or the terminal to determine the first frequency domain resource may include at least one of the following:

[0164] In some embodiments, the first frequency domain resource may be determined under the second condition, where the first frequency domain resource is associated with at least one of the initial downlink bandwidth (initial DL BWP), control resource group #0 (COERSET#0), and the LP-SS. That is, the first frequency domain resource may be determined based on a correlation between the first frequency domain resource and at least one of the initial downlink bandwidth (initial DL BWP), control resource group #0 (COERSET#0), and the LP-SS.

[0165] In some embodiments, the second condition may be that the operating frequency band of the low power wake-up receiver LP-WUR of the terminal is the same as the operating frequency band of the main receiver MR of the terminal.

[0166] The methods of the following Examples 4 and 5 can determine the first frequency domain resources based on the correlation between the first frequency domain resources and at least one of the initial downlink bandwidth initial DL BWP, control resource group #0 COERSET #0, and LP-SS when the operating frequency band of the low power wake-up receiver LP-WUR of the terminal is the same as the operating frequency band of the main receiver MR of the terminal.

[0167] Example 4

[0168] Based on the first signaling, the first frequency domain resource is determined to be the frequency domain location of any one of the initial DL BWP, COERSET#0, and LP-SS. That is, the network device can indicate the location of the first frequency domain resource through the first signaling.

[0169] In other words, when the operating frequency band of the terminal's low-power wake-up receiver LP-WUR is the same as the operating frequency band of the terminal's main receiver MR, for example, the operating frequency band of LP-WUR and the operating frequency band of MR are both n1 bands. At this time, the frequency domain resource size of LP-WUS can be predefined by the protocol. At this time, only the position of the first frequency domain resource can be indicated, which can be the same as the frequency domain position of any one of initial DL BWP, COERSET#0, and LP-SS, that is, it has the same starting position.

[0170] For example, when the first signaling indicates that the first frequency domain resource is the same as the frequency domain position of the initial DL BWP, the frequency domain position of the first frequency domain resource is the frequency domain position of the initial DL BWP; when the first signaling does not indicate that the first frequency domain resource is the same as the frequency domain position of the initial DL BWP, the frequency domain position of the first frequency domain resource can be the frequency domain position of COERSET#0.

[0171] For example, the protocol pre-defines that the frequency domain position of the initial DL BWP is 1, the frequency domain position of COERSET#0 is 2, and the frequency domain position of the LP-SS is 3. The first signaling may carry at least one of 1, 2, and 3 to indicate the frequency domain position of the first frequency domain resource. For example, when the first signaling carries 1, the terminal may determine that the frequency domain position of the first frequency domain resource is the initial DL BWP frequency domain position based on the received first signaling.

[0172] Example 5

[0173] Based on protocol pre-definition, when the terminal does not receive any indication, the first frequency domain resource is determined to be the frequency domain position of any one of initial DL BWP, COERSET#0, and LP-SS. That is, the position of the first frequency domain resource can be determined based on protocol pre-definition.

[0174] In some embodiments, optionally, the above indication may be a first signaling sent by the network device to the terminal, that is, when the network device does not send a first signaling to the terminal to indicate the location of the first frequency domain resource, the location of the first frequency domain resource may be determined based on protocol predefinition.

[0175] With the same method as in Example 4, when the low-power consumption of the terminal is awakened, it is determined that the operating frequency band of the receiver LP-WUR is the same as the operating frequency band of the terminal's main receiver MR. For example, the operating frequency band of LP-WUR and the operating frequency band of MR are both n1 frequency bands. At this time, the frequency domain resource size of LP-WUS can be predefined by the protocol. At this time, only the position of the first frequency domain resource can be indicated, which can be the same as the frequency domain position of any one of initial DL BWP, COERSET#0, and LP-SS, that is, it has the same starting position.

[0176] For example, when it can be determined based on protocol pre-definition that the first frequency domain resource is the same as the frequency domain position of the initial DL BWP, the frequency domain position of the first frequency domain resource is the frequency domain position of the initial DL BWP; when the protocol does not define that the first frequency domain resource is the same as the frequency domain position of the initial DL BWP, the frequency domain position of the first frequency domain resource can be the frequency domain position of COERSET#0.

[0218] The following is an exemplary introduction to the above method.

[0219] The method shown in the embodiment of the present disclosure relates to a method for indicating LP-WUS frequency domain resources.

[0220] This method may indicate frequency domain resources used by a terminal to monitor LP-WUS signals. The specific content of this method is as follows.

[0221] Option 1

[0222] The method in Solution 1 can define or indicate the frequency domain resources of the LP-WUS signal when the LP-WUR and MR operate in the same or different frequency bands. For example, it can be defined or indicated based on the frequency domain resources of the LP-SS.

[0223] Example 1

[0224] The network indicates the size of the LP-WUS frequency domain resources and their offset relative to the LP-SS frequency domain resources in the SIBX. This offset can be at the RB level or the RE level. The SCS of the RB / RE uses the same SCS when confirming the LP-SS frequency domain position.

[0225] Example 2

[0226] When the network puts the MR into sleep state according to service requirements, the size of the LP-WUS frequency domain resources and its offset relative to the LP-SS frequency domain resources can be indicated through RRC signaling / MAC signaling. This offset is at the RB level or the RE level. The SCS of the RB / RE uses the same SCS when confirming the LP-SS frequency domain position.

[0227] Example 3

[0228] When the signaling does not configure the size of the frequency domain resources of the LP-WUS and / or its offset relative to the frequency domain resources of the LP-SS, the terminal uses the frequency domain range of the LP-SS as the frequency domain bandwidth of the LP-WUS and / or the frequency domain position of the LP-SS as the frequency domain of the LP-WUS.

[0229] Option 2

[0230] The method in solution 2 can monitor LP-WUS at the frequency domain position of initial DL BWP, CORESET#0 or LP-SS through signaling when LP-WUR and MR operate in the same frequency band.

[0231] Option 3
