[0221] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 , an access network device 102 , and a core network device 103 .

[0222] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

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

[0226] In some embodiments, the core network device 103 includes, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0227] 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 provided by the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0228] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0229] 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 (D2b) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other information transmission methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0230] 3GPP standard Release 15 (R15) introduced the fifth generation (5G). 5G terminals consume very high energy. To achieve this, a number of terminal energy-saving technologies have been introduced, including Connected Discontinuous Reception (C-DRX), which is supported by both 4G and 5G, and measurement relaxation.

[0231] To further achieve terminal energy saving, R16 introduces a wake-up signal (WUS) for radio resource control (RRC) terminal energy saving. An offset before the UE C-DRX on-duration defines a duration for sending the WUS signal. During the WUS duration, the WUS signal, i.e., downlink control information (DCI) 2-6, is sent, scrambled by the PS-RNTI, to indicate whether the terminal should wake up during the next UE C-DRX on-duration to monitor the physical downlink control channel (PDCCH), or wake up.

[0232] In Release 17, a paging WUS was introduced to save energy for terminals in the RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE). This WUS, also known as the Paging Early Indication (PEI), is sent sometime before the Paging Occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled by the Paging Early Indication Radio Network Temporary Identifier (PEI-RNTI).

[0233] As shown in Figure 1b, to further achieve terminal energy conservation, a low-power wake-up receiver (LP-WUR), also known as a low-power wake-up signal (LP-WUS), can be introduced. The base station can send an LP-WUS to the terminal to wake up the terminal when the main transceiver is asleep. Specifically, the main transceiver is asleep, and a separate low-power receiver is used to receive the LP-WUS. After receiving the LP-WUS, the low-power receiver can wake up the terminal's main receiver to perform data transmission and reception operations. The power consumption of the terminal's low-power receiver is much lower than that of the terminal's main receiver.

[0234] MBS is divided into MBS broadcast service and MBS multicast service. In the MBS broadcast service, two bits are used in the MCCH DCI to indicate the start, end, configuration change, etc. of the MBS broadcast service. In the MBS multicast service, a terminal in the RRC connected state (RRC_CONNECTED) receives the multicast service. When there is no multicast service data to be sent, the terminal can return to the RRC idle state (RRC_IDLE) / RRC inactive state (RRC_INACTIVE). In the RRC idle state / RRC inactive state, the terminal is still in the state of participating in the multicast service. When there is multicast service data to be sent, the access network device needs to send a multicast paging to notify the terminal to enter the RRC_CONNECTED state to continue receiving multicast service data. The terminal needs to receive the multicast paging, which will cause a delay.

[0703] FIG5 is an interactive diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in FIG5 , the present disclosure embodiment relates to an information transmission method for a communication system 100, and the method includes one of the following steps:

[0704] Step S5101: The access network device sends an LP-WUS to the terminal.

[0705] In some embodiments, the LP-WUS carries first information associated with a first multicast broadcast service MBS.

[0706] In some embodiments, the LP-WUS is classified into at least one category; and / or the LP-WUS carries first information of different categories.

[0707] For optional implementations of step S5101, please refer to step S2101 of Figure 2a, step S2203 of Figure 2b, step S2301 of Figure 2c, step S3101 of Figure 3a, step S3202 of Figure 3b, step S3301 of Figure 3c, step S3401 of Figure 3d, step S4101 of Figure 4a, step S4202 of Figure 4b, step S4301 of Figure 4c, step S4401 of Figure 4d, and other related parts of the embodiments involved in Figures 2a, 2b, 2c, 3a, 3b, 3c, 3d, and 4a to 4f, which will not be repeated here.

[0708] The following provides a specific example in combination with any of the above embodiments:

[0709] Solution 1: MCCH channel monitoring.

[0710] The terminal receives the LP-WUS, which carries indication information. The indication information indicates the status of the MBS broadcast service, that is, start, end, configuration change, etc.

[0711] The further indication information is 2 bits, and each bit represents the following:

[0712] A high-order bit of "1" indicates the start of the MBS broadcast service. A low-order bit of "1" indicates a configuration change for the MBS broadcast service, excluding MCCH information changes caused by a new MBS broadcast. These changes may include configuration changes for an ongoing MBS broadcast service session, changes caused by the cessation of the MBS broadcast service, and changes caused by changes in neighboring cell information.

[0713] Solution 2: MBS configuration and LP-WUS configuration.

[0714] When the UE is receiving or interested in receiving an MBS service, the UE ignores the configuration of the LP-WUS and protects the receiving state of the MR.

[0715] Solution 3: Group paging monitoring.

[0716] The terminal receives an LP-WUS, which carries an indication information indicating the identification information of the activated MBS multicast service. The identification information of the MBS multicast service may be:

[0717] Option 1: MBS multicast service identification information TMGI.

[0718] Option 2: MBS multicast service identification information G-RNTI or GS-RNTI.

[0719] Option 3: An index used to identify the MBS multicast service identifier TMGI, where the index is based on a mapping relationship between a network configuration index and the TMGI.

[0720] Based on the indication in the LP-WUS, if the MBS service of the MBS group to which the UE joins is activated, the UE enters the RRC connected state (RRC_CONNECTED) and prepares to receive the MBS multicast service.

[0721] On the network side, as shown in Figure 6, before sending multicast paging, the AMF obtains the ability of users in the MBS group to support LP-WUS, and then the AMF instructs the base station in multicast group paging (MULTICAST GROUP PAGING) whether to use LP-WUS notification to activate MBS, or use the traditional method, or use both to send multicast paging to the UE.

[0722] Scheme 4: Classification of LP-WUS commands.

[0723] The LP-WUS includes various information, but its size is limited, meaning it can only carry a limited amount of information. Therefore, more LP-WUS signaling / command categories / types can be defined. Each LP-WUS type / category will include corresponding information, reducing the size of the LP-WUS.

[0724] Option 1: The LP-WUS command includes an indication message that indicates the LP-WUS category. Different LP-WUS categories carry different information content. Upon receiving the LP-WUS, the terminal decodes the information in the LP-WUS based on the category.

[0725] Option 2: Different LP-WUS categories are distinguished based on different transmission timings, different frequency domain resources, or different scrambling code resources. Upon receiving the LP-WUS, the terminal identifies the LP-WUS category based on the timing of receiving the LP-WUS, the frequency domain resources, or the descrambling code resources, and decodes the information in the LP-WUS based on the category.

[0726] Option 3: If the LP-WUS command is too large, the LP-WUS is segmented. The LP-WUS contains the segment numbers of the segments carried by the current LP-WUS and / or an identifier that identifies all segments as a single LP-WUS command. Upon receiving multiple LP-WUSs, the terminal sorts them according to the segment numbers in the LP-WUS and assembles all segments according to the identifier that identifies all segments as a single LP-WUS command to form a complete LP-WUS command.

[0727] Before receiving the LP-WUS command, obtain the LP-WUS reception related configuration information. Based on system broadcast information, or dedicated signaling from the MR link. The configuration information can be:

[0728] The monitoring duty cycle of LP-WUS;

[0729] Monitoring frequency resources of LP-WUS (e.g., 20 sub-channels in a 5 MHz frequency resource);

[0730] Monitoring time domain resources of LP-WUS (e.g., time slot index within a cycle);

[0731] The scrambling code used to address the UE (e.g., the scrambling code within a subchannel and / or time slot);

[0732] Valid range or timer for LP-WUS configuration; Radio Network Temporary Identity (RNTI) for a specific group of LP-WUS activation / deactivation;

[0733] LP-WUS waveform; beam scanning related configuration of LP-WUS transmission;

[0734] Frequency offset and / or downlink (DL) timing offset between LRs.

[0735] This embodiment provides monitoring of MBS broadcast service status and / or monitoring of MBS multicast service based on LP-WUS indication, so that terminals supporting MBS multicast service and / or broadcast service can also obtain energy saving benefits brought by LP-WUS.
