Description

Technical Field

[0001] This application relates to the field of terminal communication technology, and in particular to a system information update method, terminal equipment, network equipment, and chip system. Background Technology

[0002] When system messages change, network devices need to indicate the changes to terminal devices so that terminal devices can initiate the system message update process and obtain the updated system messages.

[0003] In current traditional implementations, system message update indications are typically part of the paging listening process. For example, the terminal device listens for DCI on the associated PO and determines whether there are any system message updates based on the DCI indication. However, when the terminal device is listening for LP-WUS, it also needs to initiate MR first when it determines that its packet has been paged based on LP-WUS, and then listen for DCI on the associated PO based on MR to determine whether there are any system message updates.

[0004] However, the power consumption of the terminal device when starting MR is relatively high, which leads to a problem of high power consumption when giving system message update instructions to the terminal device in the LP-WUS listening state. Summary of the Invention

[0005] This application provides a system information update method, a terminal device, a network device, and a chip system, which are applied in the field of communication technology to reduce the power consumption of the terminal device when updating system messages.

[0006] Firstly, embodiments of this application propose a system information updating method. Applied to a terminal device, the terminal device including a low-power receiver and a main receiver, the method includes:

[0007] When the main receiver is in a low-power state, the low-power receiver receives first indication information from the network device;

[0008] When the first indication information indicates that there is an update to the system information of the first category, after the first event triggers the start of the main receiver, the main receiver executes the system information update process according to the first indication information.

[0009] In this implementation, by waiting for other events to trigger MR when the first indication information indicates that the system information of the first category has been updated, unnecessary power consumption caused by the terminal device initiating MR to update unnecessary system information can be saved. After other events trigger MR, the terminal device can update the system information based on MR, thereby ensuring the comprehensiveness of the system information maintained by the terminal device and avoiding functional abnormalities of the terminal device.

[0010] In one possible implementation, the method further includes:

[0011] If the first indication indicates that the system information of the second category has been updated, the main receiver is started according to the first indication and the system information update process is executed.

[0012] In this implementation, when the first indication information indicates that the second category of system information has been updated, the terminal device can initiate MR (Metal Transport Manager) based on the first indication information (which can be understood as the first indication information triggering the initiation of MR, specifically, the initiation of MR immediately upon receiving the first indication information) to update the system information. This ensures that the terminal device can perform timely maintenance on necessary system information, guaranteeing the normal operation of all terminal device functions. The "immediate initiation" can mean starting immediately or very soon after receiving the first indication information. The initiation of MR can be initiated by the low-power receiver sending a wake-up signal to the MR.

[0013] In one possible implementation, the method further includes:

[0014] When the first indication indicates that the system information of the second category has been updated, the time interval between the moment when the terminal device starts executing the system information update process and the moment when it receives the first indication is t2; when the first indication indicates that the system information of the first category has been updated, the time interval between the moment when the terminal device starts executing the system information update process and the moment when it receives the first indication is t1; wherein, t2 is less than t1.

[0015] In one possible implementation, the first category of system information is non-essential system information, while the second category of system information is essential system information.

[0016] In one possible implementation, the second category of system information includes at least one of the following: Low Power Wake-up Signal (LP-WUS) configuration information, Paging Advance Indication (PEI) configuration information, Paging Timing (PO) configuration information, and Cell Access Restriction Information.

[0017] In this implementation, the configuration information used when listening to LP-WUS is identified as necessary system information to ensure that the terminal device can perform its functions normally.

[0018] In one possible implementation, the first indication information is carried in an LP-WUS;

[0019] The LP-WUS includes load information, which has n bits, where n is an integer greater than or equal to 1.

[0020] In this implementation, the load information carried by LP-WUS indicates which category of system information has been updated. This allows the UE to send two types of update indications to the terminal device without initiating MR, thus effectively saving power consumption.

[0021] In one possible implementation, the content type of the payload information is a code point type, and m bits out of the n bits are used to characterize the first indication information, where m is an integer greater than or equal to 1 and less than or equal to n;

[0022] When the m bits correspond to a first value, the first indication information is used to indicate that the system information of the first category has been updated;

[0023] When the m bits correspond to a second value, the first indication information is used to indicate that the system information of the second category has been updated.

[0024] In this implementation, for codepoint type payload information, it is possible to simply and effectively represent the two different meanings of the first indication information, thereby effectively indicating to the terminal device which type of system information has been updated.

[0025] In one possible implementation, the first and second values ​​do not overlap with the subgroup number corresponding to the terminal device. This effectively avoids conflicts in load information indication and prevents abnormal indication situations.

[0026] In one possible implementation, the content type of the payload information is a bitmap type, and the first set consisting of at least one bit among the n bits is used to characterize the first indication information;

[0027] When the values ​​of each bit in the first set are the first combination of values, the first indication information is used to indicate that the system information of the first category has been updated;

[0028] When the values ​​of each bit in the first set are the second combination of values, the first indication information is used to indicate that the system information of the second category has been updated.

[0029] In this implementation, for bitmap type payload information, it is possible to simply and effectively represent the two different meanings of the first indication information, thereby effectively indicating to the terminal device which type of system information has been updated.

[0030] In one possible implementation, the first set includes the i-th bit and the j-th bit among the n bits;

[0031] The first value combination includes: the i-th bit is a first value, and the j-th bit is a second value;

[0032] The second combination of values ​​includes: the i-th bit is a third value, and the j-th bit is a fourth value;

[0033] Where i and j are both integers greater than or equal to 1 and less than or equal to n.

[0034] In one possible implementation, the t-th bit of the n bits is used to indicate the content type of the payload information, where t is an integer greater than or equal to 1 and less than or equal to n.

[0035] In this implementation, the type of payload information is indicated by the t-th bit, so the specific type of payload can be flexibly configured according to the actual situation of the terminal device associated with the PO, so as to give full play to the advantages of the corresponding type.

[0036] In one possible implementation, the method further includes:

[0037] Receive a second indication information from the network device, the second indication information being used to indicate whether the t-th bit is used to indicate the content type of the payload information.

[0038] In this implementation, the specific function of the t-th bit can be flexibly configured based on the second indication information to improve the utilization rate of each bit in the load information.

[0039] In one possible implementation, the first event includes at least one of the following: receiving a paging message, stopping LP-WUS listening, performing MR measurements, and a deletion cycle of arriving system information.

[0040] In one possible implementation, the deletion period is p times the first duration, where p is an integer greater than or equal to 1.

[0041] In one possible implementation, p is configured by the network device, or p is pre-negotiated between the network device and the terminal device.

[0042] In one possible implementation, the deletion period is configured for the network device.

[0043] In this implementation, the power consumption of terminal devices can be effectively saved by redefining the deletion cycle of system information.

[0044] In one possible implementation, the method further includes:

[0045] Send power consumption information to network devices to start the main receiver;

[0046] The deletion period or the multiple p sent by the network device is received.

[0047] In this implementation, the terminal device reports the energy consumption information for starting MR to the network device, and then the network device configures the deletion period or multiple p to the terminal device. This can effectively improve the compatibility between the configured deletion period and the terminal device, while also effectively saving the power consumption of the terminal device.

[0048] In one possible implementation, after the system information deletion cycle has elapsed, the method further includes:

[0049] After the second event triggers the main receiver to start, the system information stored in the terminal device is deleted, and the system information update process is executed.

[0050] The second event may include at least one of the following: receiving a paging message, stopping listening to LP-WUS, and performing MR measurements.

[0051] In this implementation, when the system information deletion cycle is reached, the terminal device waits for the second event to trigger MR before executing the system information update process. This avoids frequently starting MR just to meet the SI update requirements corresponding to the deletion cycle, thereby effectively saving power consumption.

[0052] Secondly, embodiments of this application propose a system information updating method. Applied to network devices, the method includes:

[0053] Send the first instruction information to the terminal device;

[0054] When the first indication information indicates that there is an update to the system information of the first category, after the main receiver of the terminal device is triggered to start by the first event, the system information update process is performed with the terminal device.

[0055] In one possible implementation, the method further includes:

[0056] If the first indication indicates that the system information of the second category has been updated, after the first indication triggers the main receiver of the terminal device to start, the system information update process is executed with the terminal device.

[0057] In one possible implementation, the first category of system information is non-essential system information, while the second category of system information is essential system information.

[0058] In one possible implementation, the second category of system information includes at least one of the following: LP-WUS configuration information, PEI configuration information, PO configuration information, and cell access restriction information.

[0059] In one possible implementation, the first indication information is carried in an LP-WUS;

[0060] The LP-WUS includes load information, which has n bits, where n is an integer greater than or equal to 1.

[0061] In one possible implementation, the content type of the payload information is a code point type, and m bits out of the n bits are used to characterize the first indication information, where m is an integer greater than or equal to 1 and less than or equal to n;

[0062] When the m bits correspond to a first value, the first indication information is used to indicate that the system information of the first category has been updated;

[0063] When the m bits correspond to a second value, the first indication information is used to indicate that the system information of the second category has been updated.

[0064] In one possible implementation, the first value and the second value do not overlap with the subgroup number corresponding to the terminal device.

[0065] In one possible implementation, the content type of the payload information is a bitmap type, and the first set consisting of at least one bit among the n bits is used to characterize the first indication information;

[0066] When the values ​​of each bit in the first set are the first combination of values, the first indication information is used to indicate that the system information of the first category has been updated;

[0067] When the values ​​of each bit in the first set are the second combination of values, the first indication information is used to indicate that the system information of the second category has been updated.

[0068] In one possible implementation, the first set includes the i-th bit and the j-th bit among the n bits;

[0069] The first value combination includes: the i-th bit is a first value, and the j-th bit is a second value;

[0070] The second combination of values ​​includes: the i-th bit is a third value, and the j-th bit is a fourth value;

[0071] Where i and j are both integers greater than or equal to 1 and less than or equal to n.

[0072] In one possible implementation, the t-th bit of the n bits is used to indicate the content type of the payload information, where t is an integer greater than or equal to 1 and less than or equal to n.

[0073] In one possible implementation, the method further includes:

[0074] Receive a second indication information from the network device, the second indication information being used to indicate whether the t-th bit is used to indicate the content type of the payload information.

[0075] In one possible implementation, the first event includes at least one of the following: receiving a paging message, stopping LP-WUS listening, performing MR measurements, and a deletion cycle of arriving system information.

[0076] In one possible implementation, the deletion period is p times the first duration, where p is an integer greater than or equal to 1.

[0077] In one possible implementation, p is configured by the network device, or p is pre-negotiated between the network device and the terminal device.

[0078] In one possible implementation, the deletion period is configured for the network device.

[0079] In one possible implementation, the method further includes:

[0080] Receive energy consumption information from the terminal device, the energy consumption information being used to indicate the energy consumption required to start the main receiver of the terminal device;

[0081] Based on the energy consumption information, the deletion period or the multiple p is sent to the terminal device.

[0082] In one possible implementation, when the system information deletion cycle arrives, the method further includes:

[0083] After the second event triggers the main receiver of the terminal device to start, the system information update process is executed with the terminal device.

[0116] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0117] 1. Terminal equipment

[0118] Terminal equipment can be any device that includes wireless transceiver capabilities and can cooperate with network equipment to provide communication services to users. Specifically, terminal equipment can refer to User Equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. For example, terminal equipment can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle equipment, wearable device, and terminal equipment in future 5G networks or networks after 5G. Here, 5G refers to the fifth generation mobile communication technology, abbreviated as 5G.

[0119] 2. Network equipment

[0120] Network equipment can be equipment used to communicate with terminal equipment. For example, it can be a base station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication system, a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or eNodeB) in an LTE system, or a relay station, access point, vehicle-mounted equipment, wearable device, and network-side equipment in future 5G networks or networks after 5G, or network equipment in future evolved Public Land Mobile Network (PLMN) networks, etc.

[0121] The network devices involved in the embodiments of this application can also be referred to as network devices or Radio Access Network (RAN) devices. RAN devices are connected to terminal devices and are used to receive data from the terminal devices and send it to the core network devices. RAN devices correspond to different devices in different communication systems. For example, in 2G systems, they correspond to base stations and base station controllers; in 3G systems, they correspond to base stations and Radio Network Controllers (RNCs); in 4G systems, they correspond to Evolutionary Node Bs (eNBs); and in 5G systems, they correspond to access network devices (e.g., gNBs, Central Units (CUs), Distributed Units (DUs)) in New Radio (NR).

[0122] 3. Core network equipment

[0123] The core network equipment may be, but is not limited to, a mobile management entity (MME) / serving gate way (SGW), etc., where MME / SGW means that the MME and the SGW are located in the same physical entity.

[0124] 4. RRC Status

[0125] 5G Radio Resource Control (RRC) includes three RRC states: RRC Connected, RRC Inactive, and RRC Idle.

[0126] In this context, the terminal device in the RRC idle state or RRC inactive state is in a sleep state. The main receiver of the terminal device in the sleep state is in a low-power state, such as being turned off or in a sleep or dormant state.

[0127] 5. System Information (SI)

[0128] Each system information (SI) contains a set of parameters related to a specific function. The SI can include one MIB (Master Information Block) and multiple SIBs (System Information Blocks). SIs can also be categorized into Minimum SIs (MSI) and Other SIs (OSI).

[0129] The MSI can include MIB and SIB1, while the OSI can include all other system information not included in the OSI, such as SIB2 to SIB9. The SIBs included in the OSI can be expanded according to actual needs, and this embodiment does not impose any restrictions on this. In one implementation, the MIB can be periodically broadcast by the system, the OSI can be periodically broadcast by the system, or it can be sent according to the needs of the terminal device.

[0130] Here is a brief introduction to the functions of MIB and various SIBs:

[0131] -MIB: Contains cell bar information and basic physical layer information of the cell required to receive further system information. In other words, the MIB contains information on how to obtain SIB1.

[0132] -SIB1: Defines the scheduling of other system information blocks and contains the information required for initial access. In other words, SIB1 contains OSI scheduling information.

[0140] -SIB9: Contains information related to GPS (Global Positioning System) time and Coordinated Universal Time (UTC).

[0141] 6. PEI

[0142] PEI (paging early indication) technology can group multiple terminal devices associated with a paging opportunity (PO) and then issue paging indications to the terminal devices in each group separately.

[0143] 7. Other terms

[0144] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with substantially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0145] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0146] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0147] To better understand the technical solution of this application, based on the concepts introduced above, the relevant technologies involved in this application will be further described in detail below.

[0148] Network devices typically configure system information for terminal devices, enabling them to perform corresponding functions. To ensure that terminal devices can accurately perform these functions, when system information changes, the network device needs to indicate to the terminal device that the system information has been updated. This prompts the terminal device to initiate a system information update process to obtain the updated system information.

[0149] In current traditional implementations, SI update instructions are usually part of the paging listening process. The following is a brief explanation of the relevant paging implementation.

[0150] In order to achieve the goal of energy conservation and emission reduction, in current communication systems, when terminal devices do not need to communicate with network devices, they can release the RRC connection and enter the RRC idle state or RRC inactive state, so as to save power and reduce power consumption.

[0151] After the RRC connection between the terminal device and the network device is released, the core network device can, for example, mark the terminal device as entering an idle or inactive state. When it needs to send downlink data to the terminal device in the idle or inactive state, the core network device must first send a paging message to all network devices in the tracking area where the terminal device is located, thereby forwarding the paging message to the terminal device through the network devices. The tracking area includes multiple cells in which the terminal device can move freely, and these multiple cells belong to at least one network device.

[0152] Correspondingly, terminal devices in idle or inactive states need to periodically listen for paging messages and then respond to these messages to initiate RRC connection or RRC recovery procedures with the network device in order to perform downlink services. Specifically, when a terminal device responds to a paging message and enters the working state, it means that the terminal device has been woken up, specifically the transceiver in the terminal device has been woken up, so that the terminal device can subsequently communicate with the network device.

[0153] And there are currently several possible paging methods, which will be discussed below. Figures 1 to 5 The implementation details of SI update instructions during the paging listening process under two different paging methods are explained respectively.

[0154] Figure 1 Implementation illustration of the paging configuration provided in the embodiments of this application Figure 1 , Figure 2 This is a schematic diagram of the structure of DCI1_0 provided in an embodiment of this application. Figure 3 This is a schematic diagram of the receiver of the terminal device provided in an embodiment of this application. Figure 4 Implementation illustration of the paging configuration provided in the embodiments of this application Figure 2 , Figure 5 Implementation illustration of the paging configuration provided in the embodiments of this application Figure 3 .

[0155] The first paging method: a paging method that decodes the PDCCH in the PO periodically.

[0156] This paging method can also be understood as the traditional paging method, or the basic mechanism of paging.

[0157] Typically, network devices configure discontinuous reception (DRX) cycles for terminal devices in RRC idle or RRC inactive states. The DRX cycle can also be understood as a paging cycle. For example, in... Figure 1 In the example, the DRX period can be 320ms. In actual implementation, the specific duration of the DRX period can be set according to actual needs. This embodiment does not impose any restrictions on this.

[0158] Additionally, network devices can configure the number of paging frames (PF) in each DRX cycle, as well as the number of paging occasions (PO) under each PF.

[0159] For example in Figure 1 In the example, four power banks (PFs) are configured within each DRX cycle: PF1, PF2, PF3, and PF4. Each PF includes two product points (POs). Figure 1 Taking PF1 as an example, this illustrates that PF1 includes PO0 and PO1. In actual implementation, the number of PFs included in each DRX cycle, and the number of POs under each PF, can be set according to actual needs. This embodiment does not impose any restrictions on this.

[0160] Reference Figure 1 It is certain that the two POs under PF1, namely PO0 and PO1, are each associated with their respective UEs. In one implementation, the UE can calculate its own PF and PO using a formula.

[0161] The formula for calculating the PF associated with the UE is shown in Formula 1 below:

[0162] (SFN+PF_offset)mod T=(T / N)×(UE_ID mod N) Formula 1

[0163] Wherein, SFN is the system frame number to be calculated, T is the paging period, N is the number of PFs in one DRX period, PF_offset is the offset of the PF, and UE_ID is the result of 5G-S-TMSI mod 1024, where 5G-S-TMSI is the 5th Generation system temporary mobile subscriber identity.

[0164] Furthermore, the formula for calculating the PO associated with the UE can be shown in Formula 2 below:

[0165] i_s=floor(UE_ID / N)mod Ns formula 2

[0166] Where Ns is the number of POs configured under a PF, and i_s is the calculated PO.

[0167] Based on the fact that each UE can determine its associated PO, the terminal device in the RRC idle state or RRC inactive state can wake up at its associated PO. For example, the terminal device can wake up the main receiver (MR) and listen for paging at the PO through the main receiver.

[0168] When the core network equipment needs to page the terminal equipment, it will instruct the network equipment to send a PDCCH at the PO associated with the terminal equipment. Therefore, when the terminal equipment is listening for paging at the PO, the terminal equipment can listen to and decode the PDCCH scrambled by P-RNTI (Paging Radio Network Temporary Identifier).

[0169] As can be determined from the above description, each UE is associated with its own corresponding PF and PO, and it can be deduced that each PO is associated with at least one UE. That is to say, each PO is shared by multiple UEs. Therefore, within a PO, all associated UEs need to listen to and decode the P-RNTI scrambled PDCCH.

[0170] Based on the above introduction, it can be determined that the traditional SI update indication can be implemented during paging listening. In one implementation, when the UE associated with the PO listens to the PDCCH, it will specifically listen to the P-RNTI scrambled DCI1_0, where DCI1_0 is used to indicate whether there is an SI update.

[0171] For example in Figure 1In the example, the UEs associated with PO0 under PF1 include UE1, UE2, UE3, etc. Then these UEs need to listen to the P-RNTI scrambled DCI1_0 at PO0 and determine whether there is an update to SI based on the indication of DCI1_0.

[0172] For example, you can refer to Figure 2 Understanding the implementation of the DCI1_0 instruction SI update, Figure 2 This is a schematic diagram of the structure of DCI1_0 provided in the embodiments of this application.

[0173] like Figure 2 As shown, DCI1_0 includes multiple fields, such as... Figure 2 The example shows a short information indicator field, which occupies two bits. It also includes a short information field, which occupies eight bits. This embodiment will not list the remaining fields included in DCI1_0.

[0174] The short message indicates that the two bits of this field can exist. Figure 2 The four value selection methods shown are as follows: Figure 2 As shown:

[0175] When the value is 00, the meaning of the "short information indicator" field is currently reserved.

[0176] When the value is 01, the meaning of the short information indicator field is: the DCI (Downlink Control Information) only contains paging scheduling information;

[0177] When the value is 10, the meaning of the short information indicator field is: DCI contains only short messages;

[0178] When the value is 11, the meaning of the short information indicator field is: the DCI contains both paging scheduling information and short messages.

[0179] Furthermore, if the short information indicator field indicates the presence of a short message, the terminal device can determine whether the SI has been updated based on the first bit of the short information field.

[0180] like Figure 2 As shown, the first bit of the "short information" field is the system information modification indicator, used to indicate whether the system information has been updated. In one implementation, when this bit is 1, it indicates that the system information has been updated; when the bit is 0, it indicates that the system information has not been updated.

[0181] In this embodiment, the specific meanings of the remaining bits of the "short information" field will not be listed. For specific implementation details, please refer to existing technologies for understanding.

[0182] The following section will further describe the paging process after paging monitoring. During the paging monitoring process, the terminal device will monitor and decode the PDCCH scrambled by P-RNTI. If the decoding is successful, the terminal device can receive the paging message at the corresponding PDSCH resource according to the paging message scheduling information (time and frequency resources, modulation and coding scheme, etc.) contained in the PDCCH.

[0183] Subsequently, if the terminal device receives a paging message at the PDSCH resource, and the paging message contains the terminal device's ID, it indicates that the terminal device has been paged. Accordingly, the terminal device can initiate procedures such as RRC connection establishment or RRC connection restoration to the network device, thereby responding to the paging message to receive downlink services.

[0184] However, if the terminal device does not listen to the P-RNTI scrambled PDCCH at PO, or if the paging message received at the PDSCH resource does not contain the terminal device's ID, the terminal device assumes it has not been paged and then returns to the sleep state.

[0185] In the paging method described above, since each PO is shared by multiple terminals, if any terminal device associated with the same PO is paged, all terminal devices associated with that PO need to receive a PDSCH paging message. For terminal devices that were not paged, this situation constitutes a false alarm, and the power consumption of these terminal devices receiving the PDSCH is also an unnecessary waste of power.

[0186] Therefore, in order to improve upon the traditional paging method described above, we can consider paging groups for terminal devices and introduce a Low Power Wake Up Signal (LP-WUS) / Low Power Wake Up Receiver (LR) to reduce the power consumption of unpaging terminal devices, which is the second paging method to be introduced below.

[0187] The second paging method: LP-WUS based paging method

[0188] The current paging method introduces LP-WUS and LR. The following is a brief explanation of these two concepts.

[0189] LP-WUS is a wake-up signal designed for small, power-sensitive, static, limited-mobility, and slow-moving terminal devices.

[0190] LR (Low Power Receiver) is a lower power receiver compared to MR (Mixed Receiver). A low-power wake-up receiver can also be called a low-power receiver. Because MR corresponds to the main radio frequency interface, it is mainly used for interactive communication with network devices, acquiring downlink data sent by core network devices, receiving complex messages from other network devices, and sending data and other messages to network devices. Therefore, MR typically has higher power consumption. LR, on the other hand, is only used to receive simpler signals, such as LP-WUS (which may only be sequence-related and do not require PDCCH decoding), etc., so LR consumes less power than MR.

[0191] In one implementation, when the UE is in the IDLE / INACTIVE state and within the wake-up signal coverage area, and meets the conditions for listening to LP-WUS, the UE can choose to listen to LP-WUS via LR, and can also choose to stop listening to PO and turn off the main radio receiver (MR) to save power. This state is called ultra-deep sleep mode.

[0192] The following is a detailed analysis of how this paging method specifically saves power:

[0193] As can be understood from the first traditional paging method described above, since the terminal device needs to listen to the P-RNTI scrambled PDCCH at the PO, the terminal device needs to wake up the MR before the PO. This means that the terminal device needs to wake up the MR regardless of whether it is being paged, and waking up the MR itself will result in a large power consumption.

[0194] To effectively reduce power consumption caused by waking up the MR, the current paging method introduces LR and LP-WUS. In one implementation, each PO is associated with an LP-WUS, and the associated LP-WUS is set before the PO.

[0195] So if Figure 3 As shown, the terminal device can first listen to LP-WUS based on the lower power LR. If LP-WUS is detected, the terminal device can then further wake up MR based on LP-WUS to listen for paging messages.

[0196] If no LP-WUS is detected, the terminal device can remain in sleep mode, thus saving power consumption from waking up the MR to listen for and receive paging messages. Therefore, for terminal devices that are not being paged, this implementation effectively saves power consumption by replacing the traditional paging reception operation of listening to the PDCCH on the PO with the simpler LP-WUS.

[0197] In addition, when waking up the MR based on LP-WUS, the terminal device can also determine whether its own group has been paged based on LP-WUS, and then determine whether to wake up the MR.

[0198] Specifically, similar to PEI, LP-WUS can also include packet information in its payload. Therefore, in the current paging method, terminal devices associated with a PO can be grouped, and paging instructions can be sent to each group separately. For example, network devices can use the payload in LP-WUS associated with the PO to specifically indicate whether the terminal devices in each group have been paged.

[0199] If LP-WUS is detected, the terminal device can further determine whether its own group has been paged based on LP-WUS. Only if it determines that its own group has been paged will the terminal device wake up MR to listen for paging messages.

[0200] The payload carried by LP-WUS may be 8 bits or 16 bits in size. This embodiment does not limit this, and the specific number of bits of the payload can be set according to actual needs.

[0201] Furthermore, the payload content carried by LP-WUS can be of two types: bitmap type and codepoint type.

[0202] In some implementations, the bitmap type can be understood as each bit in the payload corresponding to a group, thus indicating whether each group has been paged.

[0203] In some implementations, the codepoint type can be understood as all bits of the payload collectively representing a sub-block number. For example, the decimal value expressed by all bits of the payload is the sub-block number.

[0204] The following example, using a payload size of 8 bits, provides an exemplary description of the implementation of the two types of instruction packets described above.

[0205] First refer to Figure 4 Description of bitmap type:

[0206] Assumption Figure 4 The LP-WUS shown is the wake-up signal associated with PO0 under PF1. Assuming that the payload in LP-WUS in the current example is of type bitmap and has 8 bits, then the multiple UEs associated with PO0 can be divided into 8 groups.

[0207] like Figure 4 As shown, assuming PO0 is associated with UE1 to UE24, these 24 UEs can be divided into 8 groups, namely SG1 to SG8, ​​as shown in the figure. Figure 4 Among them, SG (subgroup)1 includes UE1, UE2, and UE3, and SG2 includes UE4, UE5, and UE6, and so on. Details of the other groups will not be listed here.

[0208] And, assuming the payload in LP-WUS is Figure 4 As shown in 00000101, one bit corresponds to one packet. Therefore, if the first and third bits in the payload are 1, it indicates that packets SG1 and SG3 are being paged. Each UE in SG1 and each UE in SG3 can then determine that their packet is being paged. Consequently, these terminal devices need to wake up the MR to listen for the paging message.

[0209] Reference Figure 4 As the introduction confirms, the bitmap implementation can indicate multiple paging packets at once, but because the payload has a limited number of bits, the number of packets for the terminal device is usually limited. For example, when the payload is 8 bits, the multiple UEs associated with the corresponding PO can only be divided into 8 packets.

[0210] Secondly refer to Figure 5 Explanation of codepoint type:

[0211] Similarly, assuming Figure 5 The LP-WUS shown here is the wake-up signal associated with PO0 under PF1, and it is assumed that the payload in the LP-WUS in the current example is of type codepoint, and the payload is 8 bits. The decimal value that 8 bits can represent is in the range of 0 to 255, so the multiple UEs associated with PO0 can be divided into 256 groups.

[0212] like Figure 5 As shown, assuming PO0 is associated with multiple UEs, then for example, these associated UEs can be divided into 255 groups, namely SG0 to SG255, as shown in the figure. Figure 4 As shown, SG1 includes UE1 and UE2, and SG2 includes UE3 and UE4, and so on. Details of the remaining groups will not be listed here.

[0213] And, assuming the payload in LP-WUS is Figure 5 The 00000101 shown here uses 8 bits to represent a decimal value, which is 5. Therefore, it can be determined that the sub-packet number indicated by the current payload is 5, and thus indicates that the SG5 packet is being paged. Each UE in SG5 can then determine that its own packet is being paged, and therefore these terminal devices need to wake up the MR to listen for the paging message.

[0214] Reference Figure 5 As the introduction confirms, the codepoint method can only indicate one paged packet at a time. However, because all bits represent a single sub-packet number, the number of packets for terminal devices can be set to be relatively large. When the number of terminal devices in packets is large, the number of terminal devices in each packet is correspondingly smaller. For example, in the current example, each packet can be set to include only two UEs, or even only one UE in a packet when the number of UEs associated with the PO is small. Therefore, when indicating whether a packet is paged based on codepoints, the false wake-up rate is relatively low.

[0215] Based on the above introduction, it can be determined that network devices can use LP-WUS to indicate which specific packet is being paged, and then the terminal devices in the corresponding packet will wake up the MR to listen for paging messages. Therefore, for the terminal devices, they need to determine their own packet. In one implementation, the terminal device can determine the sub-packet number as shown in Formula 3 below:

[0216] LPWUSSubgroupID=floor(UE_ID / (N*Ns) mod subgroupsNumForLpwusUEID+(subgroupsNumPerPOForLpwus–subgroupsNumForLpwusUEID) Formula 3

[0217] First, it should be noted that there are two dimensions to the paging packets for the UE. One dimension is the packet sent to the UE by the core network device, which is referred to as the UE's core network packet in this embodiment. The other dimension is the packet determined by the network device based on the UE ID, which is referred to as the UE ID-based packet in this embodiment. Based on this, the parameters in Formula 3 described above have the following meanings:

[0218] -subgroupsNumForLpwusUEID: The number of UE-ID-based packets in the PO. This parameter can be broadcast in system information (such as SIB).

[0219] -subgroupsNumPerPOForLpwus: The total number of core network packets (if any) and UEID-based packets (if any) supported in a PO. This parameter can also be broadcast in system information (such as SIB).

[0220] Furthermore, the UE_ID in Formula 3 above can be the result of 5G-S-TMSI mod X. In one implementation, X is 32768 when eDRX (extended discontinuous reception) is used, and 8192 otherwise. The specific value of X can also be determined as the protocol evolves, and is not limited to the implementation described here. In other words, this embodiment does not impose any special restrictions on the specific value of X.

[0221] And LPWUSSubgroupID in Formula 3 is the subgroup number corresponding to the UE obtained from the calculation.

[0222] In the paging method described above, the SI update indication is also performed during the paging message listening process. Specifically, when the UE receives the LP-WUS and determines that its subgroup has been paged based on the LP-WUS, the UE will enter the paging message listening process, thereby listening for the P-RNTI scrambled DCI1_0 on the PO, and determining whether there is an SI update based on the indication of DCI1_0.

[0223] In the current paging method, LP-WUS is used to instruct the PO whether each group has been paged. Only when the UE's group is paged will the UE be woken up to detect SI updates during the paging message listening process. Therefore, it is necessary to consider how to configure LP-WUS when system information is updated.

[0224] In one implementation, LP-WUS can be configured to wake up all UEs. That is, each packet under the PO is paged by LP-WUS, and then each terminal device associated with the PO will listen for the P-RNTI scrambled DCI1_0 on the PO and determine whether there is an update to the SI based on the indication of DCI1_0.

[0225] However, when a UE is listening to LP-WUS, it doesn't actually need to synchronously maintain all SIs. For example, if the configuration for whether emergency calls are supported in SIB1 changes, assuming the network device configures LP-WUS to wake up all UEs to update their SIs to obtain the latest configuration for emergency call support, but the UE doesn't need to make an emergency call at this time, then this SI update is actually meaningless. After updating the SI, the UE might immediately disable MR and use LR to listen to LP-WUS signals again.

[0226] However, the power consumption of the UE initiating MR is approximately 15,000 to 40,000 uint. For reference, the power consumption of the UE receiving the PDCCH is only 100 uint. Therefore, it can be understood that the power consumption of the UE initiating MR is extremely high. In this embodiment, uint is a unit of power consumption in the deep sleep state, which can be understood as the UE power consumption in the deep sleep state being 1 uint. Initiating MR can be understood as bringing the MR from a low-power state into a working state, which can be understood as the traditional state of listening to the PO.

[0227] Based on the above analysis, it is understandable that the current implementation method has the following drawback: the terminal device in the LP-WUS listening state does not need to maintain all SIs synchronously. In other words, some SIs are not needed by the terminal device. Therefore, waking up the terminal device to maintain these unnecessary SIs will cause unnecessary power consumption.

[0228] Therefore, the technical solution of this application considers the following strategy: the terminal device does not need to maintain all SIs, but only maintains a portion of specific SIs. That is, LP-WUS is configured to wake up the terminal device only when certain specific SIs are updated, so that the terminal device can detect whether the SIs are updated during the listening process.

[0229] However, analysis revealed that this strategy still has problems. If the terminal device only maintains certain specific SIs, then if the terminal device needs to use the unmaintained SIs to perform corresponding functions, it may cause abnormalities in the implementation of the terminal device's functions.

[0230] For example, if the random access configuration belongs to the unmaintained SI (System Indicator), then if the random access configuration changes, the terminal device in LP-WUS listening mode will not maintain the updated random access configuration. Subsequently, if the terminal device starts MR (Mobile Ranking) and receives a paging message, problems may occur during the random access process.

[0231] Therefore, this application further proposes the following technical concept: system information is divided into two categories, one category being necessary system information and the other being non-essential system information. When necessary system information is updated, the terminal device can immediately activate MR to update the necessary system information in a timely manner; when non-essential system information is updated, the terminal device can delay updating the non-essential system information. Specifically, the update event (such as indication information indicating that the non-essential system information has been updated) can be stored, and MR is not activated because the non-essential system information has been updated. Instead, MR is activated only after other events trigger it, and then the non-essential system information is updated using the MR activated by those other events. This reduces the number of times MR is activated, effectively saving energy consumption caused by MR activation while ensuring that the terminal device can comprehensively update various system information. In summary, when system information is updated, the terminal device adopts different update mechanisms for different categories of system information. On the one hand, this ensures that the terminal can update necessary system information that has a significant impact on its business in a timely manner, so as to prevent serious problems from occurring in the terminal's business. On the other hand, when non-essential system information that has little impact on the terminal's business is updated, the update of the non-essential system information can be temporarily suspended, and the update of the non-essential system information can be carried out when MR is started by other events. This reduces the number of times MR is started, saves the energy consumption caused by MR starting, and also ensures that the terminal device can comprehensively update various system information.

[0232] Based on the above description, the system information update method provided in this application will be described in detail below with reference to specific embodiments.

[0233] First, combine Figure 6 This section introduces the implementation of updating non-essential system information. Figure 6 Interaction flow of the system information update method provided in the embodiments of this application Figure 1 .

[0234] like Figure 6 As shown, the method includes:

[0235] S601, The network device sends the first instruction information to the terminal device.

[0236] When system information is updated, the network device can send a first indication message to the terminal device, wherein the first indication message is used to indicate that the system information has been updated. More specifically, in this application, the first indication message is also used to indicate which specific category of system information has been updated.

[0237] In the current embodiment, the first indication information indicates that the system information of the first category has been updated, wherein the system information of the first category is non-essential system information (non-essential SI). The specific system information included in the non-essential system information can be set according to actual needs, and this embodiment does not limit it in this regard.

[0238] S602, The terminal device saves the first instruction information.

[0239] After receiving the first indication information, the terminal device can determine that the system information of the first category has been updated, which means that the updated system information is unnecessary. In this case, the terminal device does not need to immediately start MR to update SI, but saves the first indication information and then waits for other events to trigger MR to start.

[0240] It should be noted that the saving of the first indication information described here is because, in the current embodiment, the terminal device will not immediately execute the system information update process based on the first indication information, but will wait until the first event triggers MR startup before executing the system information update process. Therefore, the terminal device will save the first indication information for a period of time, and then execute the system information update process based on the first indication information after the first event triggers MR startup.

[0241] S603. After the first event triggers the main receiver to start, the terminal device and the network device execute the system information update process according to the first instruction information.

[0242] The terminal device waits for other events to trigger the main receiver to start. For example, after the first event triggers the MR to start, the terminal device's MR can execute a system information update process based on the saved first indication information. For example, the terminal device's MR can respond to the indication of the first indication information and perform corresponding data interaction with the network device to execute the system information update process, thereby updating the corresponding system information.

[0243] In this embodiment, the first event is an event that triggers MR activation. In one implementation, the first event can be any of the following: the terminal device receives a paging message, the terminal device stops listening to LP-WUS, the terminal device performs MR measurement, or the system information deletion cycle is reached. The paging message can include voice paging, data paging, or PWS (Public Warning System) paging, etc. In actual implementation, the first event can be expanded according to actual needs; any event that triggers MR activation can be used as the first event in this embodiment.

[0244] In this embodiment, by waiting for other events (events distinct from those causing unnecessary system information updates) to initiate MR when the first indication information indicates that a first category of system information (unnecessary system information) has been updated, unnecessary power consumption caused by the terminal device initiating MR to update unnecessary system information can be avoided. After other events trigger MR activation, the terminal device can then update the unnecessary system information based on the MR activated by other events, thereby ensuring the comprehensiveness of the system information maintained by the terminal device and preventing functional abnormalities of the terminal device.

[0245] Secondly, combine Figure 7 This section describes the implementation of necessary system information updates. Figure 7 Interaction flow of the system information update method provided in the embodiments of this application Figure 2 .

[0246] like Figure 7 As shown, the method includes:

[0247] S701, The network device sends the first instruction information to the terminal device.

[0248] In the current embodiment, the first indication information indicates that the second category of system information has been updated, wherein the second category of system information is essential system information (SI). Exemplarily, the second category of system information may include at least one of the following: LP-WUS configuration information, PEI configuration information, PO configuration information, and cell access restriction information (i.e., cell bar).

[0249] In actual implementation, the specific system information included in the necessary system information (i.e., the second category of system information) can be set according to actual needs, and this embodiment does not impose any restrictions on this.

[0250] S702, The terminal device starts the main receiver.

[0251] After receiving the first instruction information, the terminal device can determine that the second category of system information has been updated, meaning that the updated system information is necessary. At this time, the terminal device can immediately start MR to update SI in a timely manner.

[0252] S703, terminal equipment and network equipment execute system information update process.

[0253] For example, after starting MR, the terminal device can perform downlink synchronization with the network device, and then perform corresponding data interaction with the network device to execute the system information update process, thereby enabling timely updates of necessary system information.

[0254] In this embodiment, when the first indication information indicates that the second category of system information has been updated, the terminal device can immediately start MR to update the necessary system information in a timely manner, thereby ensuring that the terminal device can maintain the necessary system information in a timely manner and that all functions of the terminal device can be executed normally.

[0255] When the first instruction indicates that the system information of the second category has been updated, the time interval between the moment the terminal device updates the system information and the moment it receives the first instruction is t2; when the first instruction indicates that the system information of the first category has been updated, the time interval between the moment the terminal device updates the system information (the moment of updating the system information can be understood as the moment when the system information update process begins) and the moment it receives the first instruction is t1; t2 can be less than t1. This can be understood as follows: when necessary system information is updated, the terminal device will update the system information promptly; when unnecessary system information is updated, the terminal device will delay updating the system information.

[0256] In the above Figure 6 and Figure 7 Based on the embodiments, in one implementation, system information that the terminal device will not use while listening to LP-WUS can be classified as non-essential system information, and system information that the terminal device may use while listening to LP-WUS can be classified as essential system information, to ensure the correctness of the terminal device in performing corresponding functions based on the system information. This embodiment does not limit the specific inclusion of essential and non-essential system information, which can be set according to actual needs.

[0257] It is understandable that, for the terminal device, it does not actually need to know which specific types of system information are included in the first type. When the terminal device subsequently performs a system information update process with the network device, the network device will naturally synchronize the updated system information to the terminal device. Therefore, during the SI update indication phase, the terminal device only needs to determine which specific category of system information has been updated based on the first indication information. Afterward, the terminal device can determine its required response: whether to wait for other events to initiate MR before executing the system information update process, or to immediately initiate MR and execute the system information update process. Therefore, the technical solution of this application embodiment does not impose any additional burden on the terminal device and can effectively achieve the purpose of saving power consumption.

[0258] Based on the two embodiments described above, it should be further explained that the "starting MR" described in this application can also be equivalent to: the UE resuming the traditional PO listening mechanism and exiting the LP-WUS listening state. In various embodiments of this application, both concepts described herein can be equivalently replaced.

[0259] The following describes the implementation method of the first indication information indicating which category of system information has been updated. In one implementation, the first indication information can be carried in an LP-WUS, and based on the above description, it can be determined that the LP-WUS includes a payload, so the update indication here can be implemented, for example, through the payload in the LP-WUS.

[0260] In LP-WUS, the payload can also be called the payload information. The payload information has n bits, where n is an integer greater than or equal to 1. Referring to the above description, it can be determined that n can be 8 or 16, or n can be any other possible value. This embodiment does not impose any restrictions on this.

[0261] Based on the above introduction, it can also be determined that the content type of the payload includes two types: codepoint and bitmap.

[0262] The following sections will introduce these two types of indication methods separately, starting with the implementation of the code point type:

[0263] Based on the above introduction, it can be determined that when the payload is a code point type, multiple bits in the payload are used to jointly represent a decimal value. This decimal value can be a sub-block number, thereby indicating that a terminal device in a certain block is being paged.

[0264] In the current embodiment, a payload is needed to indicate whether the first type of system information has been updated, or to indicate whether the second type of system information has been updated. For example, two values ​​that do not conflict with the sub-group number of the terminal device can be selected to represent the two meanings respectively.

[0265] For example, a first value can be used to indicate that the system information of the first category has been updated, and a second value can be used to indicate that the system information of the second category has been updated. The specific selection of the first and second values ​​can be arbitrarily set according to actual needs, as long as the first and second values ​​do not overlap with the subgroup number corresponding to the terminal device, so as to avoid the abnormal situation caused by the same value corresponding to two meanings.

[0266] In this embodiment, m bits out of the n bits in the payload can be used to represent the specific meaning of the first indication information. Here, m can be equal to or less than n, corresponding to two different implementation methods, which will be discussed below. Figure 8 and Figure 9 They will be introduced separately. Figure 8 Implementation illustration of the load information provided in the embodiments of this application Figure 1 , Figure 9 Implementation illustration of the load information provided in the embodiments of this application Figure 2 .

[0267] In one implementation, if m equals n, then all n bits of the payload are used to represent the first indication information. Specifically, the n bits of the payload collectively represent a decimal value, which can then be used to indicate the meaning described above.

[0268] like Figure 8 As shown, assuming n is 8, the payload contains 8 bits. These 8 bits are used to collectively represent a decimal value. For example, suppose 254 is chosen as the first value and 255 is chosen as the second value.

[0269] Then refer to Figure 8 When the 8 bits of the payload are set to 1, 1, 1, 1, 1, 1, 0, the corresponding decimal value of the payload is 254, which is the first value. In this case, the first indication information is used to indicate that the system information of the first category has been updated, that is, the non-essential system information has been updated.

[0270] Furthermore, when the 8 bits of the payload are 1, 1, 1, 1, 1, 1, 1, 1, the corresponding decimal value of the payload is 255, which is the second value. In this case, the first indication information is used to indicate that the system information of the second category has been updated, that is, the necessary system information has been updated.

[0271] In this implementation, the two different meanings of the first indication information can be represented simply and effectively based on the codepoint type payload, thereby effectively indicating to the terminal device which type of system information has been updated.

[0272] In another implementation, since both bitmap and codepoint types have their own advantages, network devices can flexibly configure the payload to be either bitmap or codepoint type according to actual needs. Therefore, a single bit can be selected from the n bits of the payload to indicate the specific type of the payload.

[0273] For example, the t-th bit out of n bits can be selected to indicate the content type of the payload, where t ranges from 1 to n. Which bit out of the n bits is specifically chosen for type indication can be selected according to actual needs; this embodiment does not impose any restrictions on this.

[0274] If we use the t-th bit out of n bits as a type indicator, then the t-th bit cannot be used to indicate a decimal value. Instead, some or all of the remaining bits (excluding the t-th bit) must be used for the numerical indication. In this case, m is less than n. The m bits out of n bits can be understood as the remaining bits excluding the t-th bit.

[0275] Specifically, m bits out of the n bits in the payload are used to represent the first indication information. Specifically, these m bits collectively represent a decimal value, which can be used to indicate the meaning described above. Furthermore, this embodiment does not limit which m bits are specifically selected; they can be set according to actual needs, as long as these m bits can collectively express the first and second values.

[0276] like Figure 9As shown, assuming n and t are both 8, the payload contains 8 bits, and the 8th bit is used to indicate the payload type. For example, when the 8th bit is 0, the payload type is bitmap; when it is 1, the payload type is codepoint. Alternatively, 0 and 1 can indicate the opposite type, and this embodiment does not limit this.

[0277] Taking 0 as an example to indicate a bitmap and 1 as an example, refer to... Figure 9 When the value of the 8th bit is 1, the terminal device can determine that the payload type is codepoint.

[0278] In one example, the m bits mentioned above can be the 1st to 7th bits (excluding the 8th bit), or m can be understood as a value of 7. These 7 bits (1st to 7th bits) are used to collectively represent a decimal value. For example, suppose 126 is chosen as the first value and 128 is chosen as the second value.

[0279] Then refer to Figure 9 When the values ​​of the 8 bits of the payload are 1, 1, 1, 1, 1, 1, 1, 0, the value of the 8th bit (the leftmost bit from right to left) is 1, which indicates that the payload type is codepoint. The values ​​of the 1st to 7th bits, 1111110, are used to represent the decimal value 126, which is the first value. In this case, the first indication information is used to indicate that the system information of the first category has been updated, that is, the non-essential system information has been updated.

[0280] Furthermore, when the values ​​of the 8 bits of the payload are 1, 1, 1, 1, 1, 1, 1, 1, the meaning of the 8th bit value of 1 is the same as above, and the values ​​of the 1st to 7th bits, 1111111, are used to collectively represent the decimal value 127, which is the second value. In this case, the first indication information is used to indicate that the second category of system information has been updated, that is, the necessary system information has been updated.

[0281] In this implementation, in addition to effectively indicating to the terminal device what type of system information has been updated, the payload type can also be configured based on the t-th bit, specifically whether it is a codepoint or a bitmap. This allows for flexible selection of the payload type based on the actual situation of the terminal device associated with the PO, so as to leverage the advantages of the corresponding type.

[0282] Next, we will introduce the implementation of the bitmap type:

[0283] Based on the above introduction, it can be determined that when the payload is a bitmap type, each bit in the payload is used to indicate a packet, thereby indicating whether the terminal device of each packet has been paged.

[0284] In the current embodiment, a payload is needed to indicate whether the first type of system information has been updated or the second type of system information has been updated. For example, at least one bit from the n bits of the payload can be used to represent these two meanings respectively.

[0285] The bits selected from the n bits to represent the above two meanings can, for example, form a first set. The number of bits included in the first set can be one or more; this embodiment does not impose any restrictions on this. Furthermore, the specific bits selected from the n bits to form the first set to represent the corresponding meanings can also be chosen according to actual needs; this embodiment does not impose any restrictions on this either.

[0286] It is understandable that when the payload is of type bitmap, the value of each bit is independent. Therefore, the two meanings mentioned above can be represented by the combination of values ​​formed by the values ​​of each bit in the first set. For example, 10 represents one meaning, 01 represents another meaning, and so on.

[0287] Therefore, in one implementation, when the values ​​of each bit in the first set are a first combination of values, the first indication information can indicate that the system information of the first category has been updated. And when the values ​​of each bit in the first set are a second combination of values, the second indication information can indicate that the system information of the second category has been updated. The specific implementations of the first and second value combinations can be set according to actual needs, and this embodiment does not impose any restrictions on them.

[0288] The first set can contain one or more bits. The following explains the cases of one or more bits respectively.

[0289] For example, suppose the first set contains 2 bits. This means that two bits were selected from n bits to form the first set, representing the corresponding meaning. If the two bits selected from n bits are represented as the i-th bit and the j-th bit, then the first set includes the i-th bit and the j-th bit.

[0290] The values ​​of i and j are both in the range of 1 to n, and i and j are not the same. Based on this, the specific values ​​of i and j can be selected according to actual needs.

[0291] The i-th and j-th bits then correspond to their respective values, forming corresponding combinations to express the two meanings described above. For example, the first value combination can be understood as: the i-th bit is the first value, and the j-th bit is the second value; and the second value combination includes: the i-th bit is the third value, and the j-th bit is the fourth value. The first to fourth values ​​are independent of each other and can be the same or different.

[0292] The following is combined Figure 10 To illustrate with specific examples, Figure 10 Implementation illustration of the load information provided in the embodiments of this application Figure 3 .

[0293] exist Figure 10 In the example, assuming that n is 8, i is 8, and j is 7, then the payload contains 8 bits, and the 8th and 7th bits of these 8 bits are selected to form the first set to represent the meaning of the first indication information.

[0294] It should be noted that in one implementation, the combination of the 8th bit being 0 and the 7th bit being 0 already has a corresponding meaning, used to indicate that the LP-WUS is currently instructing the terminal device to page certain packets. In other words, the 00 value combination is already occupied, therefore it cannot be used to represent the meaning of the aforementioned first indication information.

[0295] exist Figure 10 In the example, suppose the combination of 0 and 1 is taken as the first combination of values, and the combination of 1 and 0 is taken as the second combination of values.

[0296] So if Figure 10 As shown, when the 8th bit in the payload is 0 and the 7th bit is 1, the values ​​of all bits in the first set form the first value combination. Therefore, the first indication information is used to indicate that the system information of the first category has been updated. Corresponding to the implementation described above, it can be understood that the first value is 0 and the second value is 1.

[0297] Furthermore, when the 8th bit in the payload is 1 and the 7th bit is 0, the values ​​of all bits in the first set become the second combination of values. Therefore, the first indication information is used to indicate that the system information of the second category has been updated. Corresponding to the implementation described above, the third value can be understood as 1 and the fourth value as 0.

[0298] Optionally, for example, 11 can be used as the first value combination or as the second value combination. This embodiment does not limit the specific implementation of the first value combination and the second value combination, as long as the first value combination and the second value combination composed of the values ​​of each bit in the first set are not occupied to express the other meanings.

[0299] In this implementation, since the 7th and 8th bits are already used to express a certain meaning, this embodiment selects the remaining value combinations other than the already occupied value combinations to represent the two meanings of the first indication information, thereby effectively avoiding the situation of indication abnormality.

[0300] Similar to the embodiments described above, network devices can also flexibly configure the payload to be either bitmap or codepoint type according to actual needs. Therefore, a specific bit can be selected from the n bits of the payload to indicate the specific type of the payload.

[0301] For example, the t-th bit out of n bits can be selected to indicate the content type of the payload, where t ranges from 1 to n. However, in this embodiment, since each bit in the bitmap is independent, when selecting a bit as the type indicator for the payload, a bit that has already been used as another indicator cannot be selected.

[0302] For example in Figure 10 In the example shown, bits 7 and 8 are already occupied for other indications, therefore they cannot be used as payload type indicators. (See reference...) Figure 10 For example, the first bit can be used to indicate the payload type. It's also important to understand that choosing a specific bit for payload type indication is optional. Figure 10 The dashed line indicates that the first bit is used to indicate the type of the payload.

[0303] In other words, in this embodiment, the value of t cannot be the same as i or j, in order to avoid conflicts in the meaning expressed by the bit.

[0304] And taking 0 as an example to indicate bitmap type and 1 as an example to indicate codepoint type, refer to... Figure 10 The first bit has a value of 0, so the terminal device can determine that the payload type is bitmap.

[0305] The above combination Figure 10 The example illustrates the implementation of selecting multiple bits from n bits to form a first set, thereby expressing the two meanings of the first indication information (also known as the update indication) described above. Figure 10 This section describes the case of selecting 2 bits. Implementations for selecting 3, 4, or even more bits can be found in the same document. Figure 10 The introduction will be adapted and extended for understanding, and will not be repeated in this embodiment.

[0306] Secondly, combine Figure 11 The case where the number of bits in the first set is 1 will be introduced. Figure 11 Implementation illustration of the load information provided in the embodiments of this application Figure 4 .

[0307] This means that a bit was selected from n bits to form the first set, representing the corresponding meaning. Assuming the selected bit is represented as the r-th bit, then the first set includes the r-th bit.

[0308] The value of r ranges from 1 to n, and the above is also referenced. Figure 10 As can be confirmed from the introduction, in some implementations, since the 7th and 8th bits are already used to express other meanings, the 7th and 8th bits cannot be selected when only one bit is chosen to express the two meanings corresponding to the first indication information. In other words, when selecting the r-th bit, the r-th bit cannot be a bit that has already been used to express other meanings.

[0309] Furthermore, when only one bit is selected to represent both meanings, the value of this single bit is itself one of the value combinations described above. For example, the first value combination can be understood as: the r-th bit is the fifth value; and the second value combination includes: the r-th bit is the sixth value. Where the fifth value is 0 and the sixth value is 1. Alternatively, the fifth value is 1 and the sixth value is 0; this embodiment does not impose any restrictions on this.

[0310] The following is combined with Figure 11 Let's illustrate with specific examples. Figure 11In the example, assuming n is 8 and r is 6, the payload contains 8 bits, and the 6th bit of these 8 bits is selected to form the first set to represent the meaning of the first indication information.

[0311] exist Figure 11 In the example, suppose the value 0 is used as the first value combination, and the value 1 is used as the second value combination.

[0312] So if Figure 11 As shown, when the 6th bit in the payload is 0, the first indication information is used to indicate that the system information of the first category has been updated. Corresponding to the implementation described above, the fifth bit can be understood to be 0.

[0313] Furthermore, when the 6th bit in the payload is 1, the first indication information is used to indicate that the system information of the second category has been updated. Corresponding to the implementation described above, the sixth bit being 1 can be understood as the sixth bit being 1.

[0314] In this implementation, since the 7th and 8th bits are already used to express a certain meaning, this embodiment selects a bit other than the 7th and 8th bits to represent the two meanings of the first indication information, so that the two meanings can be indicated simply and effectively with a single bit.

[0315] and the above Figure 10 The description is similar; for example, you can choose the t-th bit out of n bits to indicate the content type of the payload, where t ranges from 1 to n. However, in... Figure 11 In the example shown, bits 6, 7, and 8 are already occupied for other indications, therefore bits 6, 7, or 8 cannot be used as payload type indicators. (See reference...) Figure 11 For example, the first bit can be used to indicate the payload type. It's also important to understand that choosing a specific bit for type indication is optional. Figure 11 The dashed line indicates that the first bit can be used as a type indicator for the payload.

[0316] In other words, in this embodiment, the value of t cannot be the same as r, nor can it be the same as the position of an already occupied bit, in order to avoid conflicts in the meaning expressed by the bit.

[0317] In summary, the above embodiments can simply and effectively represent two different meanings of the first indication information based on a bitmap-type payload, thereby effectively indicating to the terminal device which type of system information has been updated. Furthermore, the payload type can be configured as either a codepoint or a bitmap based on the t-th bit, allowing for flexible selection of the specific payload type according to the actual situation of the terminal device associated with the PO, thus leveraging the advantages of the corresponding type.

[0318] In the above Figures 8-11 Based on the examples described, it can be understood that the payload type can be implemented in the following ways:

[0319] The first implementation is that the payload type is fixed, either a bitmap or a codepoint, so the terminal device can directly parse the payload according to the fixed type.

[0320] The second implementation involves the network device flexibly configuring the payload type (bitmap or codepoint) based on the t-th bit out of n bits. The terminal device then needs to first parse the t-th bit to determine the payload type, and then parse the payload accordingly based on the type indicated by the network device to correctly obtain the network device's instructions.

[0321] For the t-th bit in the second implementation, there are also two implementation methods. One is that the network device and the terminal device pre-negotiate that the t-th bit is used to indicate the payload type, meaning that the t-th bit is used to indicate the payload type by default. This implementation method does not require additional indication, thus having the advantage of lower signaling overhead.

[0322] Another approach involves the network device further informing the terminal device via a second indication that the t-th bit is used to indicate the payload type. Alternatively, the second indication can be understood as indicating the presence of a bit used to indicate the payload type. Only when the second indication indicates the presence of a bit indicating the payload type, or indicates that the t-th bit is used to indicate the payload type, will the terminal device determine the payload type based on the t-th bit. This implementation allows for flexible configuration of the specific function of the t-th bit through the second indication, thereby expanding the use of the t-th bit according to actual needs and improving the utilization rate of each bit in the payload.

[0323] In the above embodiments, it can be understood that the two implementations—the payload indicating which specific category of system information has been updated and the payload indicating the specific type of the payload—are combined. Extensibly, this implementation where a specific bit in the payload indicates the payload type can also be a separate solution.

[0324] In other words, assuming that the payload is not used to indicate which specific category of system information has been updated, the payload can also indicate the type of the payload on its own.

[0325] Specifically, the t-th bit out of the n bits in the payload can be used to indicate the content type of the payload. For example, when the t-th bit is 0, it indicates that the payload type is bitmap, and when the t-th bit is 1, it indicates that the payload type is codepoint. Alternatively, 1 can indicate the type as codepoint and 0 can indicate the type as bitmap; this embodiment does not impose any restrictions on this.

[0326] The t-th bit can be any of the n bits, as long as the t-th bit itself does not indicate the meaning of the others. For example, the 8th bit can be chosen as the bit indicating the type.

[0327] In this implementation, some or all of the remaining bits (excluding the t-th bit) of the n bits in the payload can be used to indicate the paging packet. Similar to the embodiments described above:

[0328] In one implementation, when the payload is of type bitmap, each bit except the t-th bit is used to indicate whether its corresponding group has been paged. Taking a payload containing 8 bits, and using the 8th bit as the bit indicating the payload type, as an example, assume the values ​​of these 8 bits are 0, 0, 0, 0, 0, 0, 1, 1. The 8th bit being 0 indicates the payload type is bitmap, the 2nd bit being 1 indicates the 2nd subgroup has been paged, and the 1st bit being 1 indicates the 1st subgroup has been paged.

[0329] In another implementation, when the payload is of type codepoint, all bits except the t-th bit are used to represent a decimal value, which is the subgroup number being paged. For example, if the payload contains 8 bits, and the 8th bit is used as the type indicator, assuming the values ​​of these 8 bits are 1, 1, 1, 1, 1, 1, 1, 1, the value 1 of the 8th bit indicates that the payload type is codepoint, and the values ​​of bits 1 through 7 (1111111) collectively represent the decimal value 127, which is used to indicate that subgroup number 127 has been paged.

[0330] Similar to the embodiments described above, the t-th bit also has two implementation methods. One is that the network device and the terminal device pre-negotiate that the t-th bit is used to indicate the payload type. The other is that the network device informs the terminal device through a second indication information that the t-th bit is used to indicate the payload type. Alternatively, it can be understood that the second indication information is used to indicate whether there is a bit used to indicate the payload type. The specific implementation can be referred to the description in the embodiments above, and will not be repeated here.

[0331] The above embodiments also introduce a first event that can trigger MR startup, one of which is the arrival of the system information deletion cycle. The following will elaborate on this first event.

[0332] The current protocol stipulates that terminal devices must delete the currently stored SI version and update the SI every three hours. In other words, the current system information deletion cycle is three hours. Therefore, every three hours, the system information deletion cycle is reached, triggering the terminal device to initiate MR to update the SI.

[0333] Analysis shows that, with a system information deletion cycle of three hours, the terminal device needs to perform 8 SI updates per day, and each SI update requires starting MR. The power consumption of starting MR once is described as 15,000 to 40,000 uint. Therefore, starting MR 8 times a day would result in a power consumption of 8 * (15,000 to 40,000) uint.

[0334] The power consumption of a terminal device performing a PDCCH+PDSCH listening operation is 300uint. Therefore, the power consumption of 8*(15000~40000)uint is roughly equivalent to a non-LP-WUS UE being mistakenly paged 400 to 1000 times a day. This is obviously a serious waste of power for UEs listening to LP-WUS.

[0335] Therefore, this application proposes the following improvements to the deletion cycle of system information:

[0336] In one implementation, when the system information deletion cycle (e.g., three hours) arrives, the terminal device may not initiate MR (Mean Mapping), meaning it may not perform the SI (System Information Update) process immediately. The terminal device waits for a second event to trigger MR activation before deleting the SI stored in the terminal device and executing the system information update process based on the MR activated by the second event. This avoids frequently initiating MR just to meet the SI update requirements corresponding to the deletion cycle, thus effectively saving the terminal device's power consumption.

[0337] The second event can be understood as any event other than the first event, "the system's deletion cycle has arrived," that can trigger MR to start. For specific implementation examples, please refer to the other first events described above. They will not be repeated here.

[0338] In another implementation, since setting the deletion period to three hours would cause the terminal device to frequently launch MR, it is possible to consider extending the three-hour deletion period.

[0339] Therefore, in this application, the deletion period of system information can be set to p times the first duration, where p is an integer greater than or equal to 1. The first duration can be, for example, 3 hours, or it can also be 6 hours, 12 hours, 24 hours, etc. This embodiment does not limit the choice of the first duration, as long as p times the first duration is greater than three hours, the purpose of saving power consumption can be effectively achieved.

[0340] In one implementation, the multiplier p described above can be negotiated between the terminal device and the network device. Alternatively, the multiplier p can also be dynamically configured by the network device. For example, the network device can configure the multiplier p to the terminal device via SIB messages, so that the terminal device can determine the specific deletion period.

[0341] In another implementation, the network device can also directly configure a specific deletion period to the terminal device. For example, the network device can configure the deletion period to be 24 hours to the terminal device through SIB messages, which also allows the terminal device to determine the specific deletion period.

[0342] Furthermore, the terminal device can also send the energy consumption information for initiating MR (e.g., the energy consumption required for the terminal device to initiate MR once) to the network device. The network device then configures a reasonable deletion period for the terminal device based on this energy consumption information. Specifically, the network device can configure a deletion period or a multiplier p for the terminal device; this embodiment does not impose any restrictions on this. Additionally, in this implementation where the terminal device reports energy consumption information, the network device can, for example, configure the deletion period or the multiplier p for the terminal device in an RRC release message.
