[0040] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication. The embodiments of this application can also be applied to these communication systems.

[0042] The communication system in this application embodiment can be applied to unlicensed spectrum, wherein unlicensed spectrum can also be considered as shared spectrum; or, the communication system in this application embodiment can also be applied to licensed spectrum, wherein licensed spectrum can also be considered as non-shared spectrum.

[0043] The communication system scenarios include non-terrestrial networks (NTN) systems and terrestrial networks (TN) systems. NTN typically uses satellite communication to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN systems, and other NTN systems may be included in the future. The communication system described in this application embodiment can be applied to either TN or NTN systems.

[0044] For example, Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of this application.

[0053] Before introducing the technical solution of this application, some related technical knowledge involved in this application will be introduced and explained. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0054] 1. Background of Network Energy Conservation

[0055] Network energy saving (NES) is of great significance for environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. Energy consumption has become a key part of operators' operating expenses (OPEX). According to a report by the GSMA (Global System for Mobile Communications Association), energy costs for mobile networks account for approximately 23% of total operating costs. Most energy consumption comes from the radio access network, more specifically from the active antenna unit (AAU), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being transmitted or received; the static part includes the power consumption at all times necessary for the operation of the radio access equipment, including power consumption when no data is being transmitted or received.

[0056] With the increasing prevalence of 5G in various industrial and geographical regions, there is a need to support very high data transmission rates to handle more advanced services and applications (such as XR). Network deployments are becoming denser, using more antennas, larger bandwidths, and more frequency bands. Considering the environmental impact of 5G, it is necessary to develop controlled, new solutions to enhance network energy efficiency. Therefore, based on the above objectives, network energy consumption models, KPIs (Key Performance Indicators), and evaluation methods have been researched and developed for the network equipment side in 5G networks to identify and study network energy-saving technologies in target deployment scenarios. The already defined power consumption model for the terminal equipment side is used as a reference. This research should focus on how to achieve more efficient dynamic and / or semi-static operation, and consider one or more network energy-saving technologies applied to the time, frequency, spatial, and power domains, combined with potential terminal equipment feedback support, potential terminal equipment auxiliary information, and information exchange or coordination technologies between network interfaces, to achieve more granular adaptive data transmission and / or reception.

[0057] It is worth noting that this study not only assesses potential network energy-saving gains, but also needs to evaluate and balance the impact on network and user performance by observing KPIs such as spectrum efficiency, capacity, user-perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and SLA (Service Level Agreement) security-related KPIs. This study should avoid having a significant impact on the aforementioned KPIs.

[0058] 2. Initial Access in 5G NR Systems

[0059] In NR systems, the initial access process for terminal devices can be completed by detecting the Synchronization Signal / PBCH Block (SSB or SS / PBCH block) on the Sync Raster. The SSB is transmitted through a Discovery Burst Transmission Window or an SSB transmission opportunity window. These windows occur periodically, and the period can be configured by the network device using higher-layer parameters. During the initial access process, the terminal device attempts to search for SSBs based on their predefined possible time-frequency locations. The detected SSBs provide time and frequency synchronization, radio frame timing, and a Cell ID (Identity Document).

[0060] One primary function of the SSB index is to allow the UE to obtain system timing information. Besides this, the SSB index also serves another function: indicating the quasi-co-location (QCL) relationship between SSBs, or in other words, indicating beam direction. QCL refers to the fact that the large-scale parameters of the channel experienced by a symbol on one antenna port can be inferred from the channel experienced by a symbol on another antenna port. These large-scale parameters can include delay spread, average delay, Doppler spread, Doppler shift, and spatial reception parameters. Specifically, in a 5G NR system, SSBs carried by different beams constitute an SSB burst set. Different SSB indices correspond to the time-domain location information of different SSBs within the burst set, and also to the specific SSB transmission beam information. SSBs with the same SSB index can be considered to have a QCL relationship; or, in other words, SSBs with the same SSB index experience the same or similar large-scale parameters of the channel. The UE can assume that the network device uses the same beam to transmit these SSBs; there is no QCL relationship between SSBs corresponding to different SSB indices, because they may come from different transmission beams of the network device and have experienced different channel transmission characteristics.

[0061] After detecting an SSB, the terminal device can determine the configuration of the Type0-PDCCH (Physical Downlink Control Channel) CSS (Chirp Spread Spectrum) set through the MIB (Master Information Block) message in the SSB. The terminal device can receive the network device's scheduling of SIB (System Information Block) 1 messages by listening to the Type0-PDCCH CSS set. Both the MIB and SIB1 messages include the serving cell's system configuration information. Furthermore, the terminal device can receive the network device's scheduling of other system messages besides SIB1 messages by listening to the Type0A-PDCCH CSS set, receive the network device's scheduling of paging messages by listening to the Type2-PDCCH CSS set, and receive the Paging Early Indication (PEI) information for paging messages sent by the network device by listening to the Type2A-PDCCH CSS set.

[0062] The terminal device can also obtain the resource configuration of PRACH Occasion (RO) during random access based on the received cell system message SIB1. RO is the time-frequency resource carrying the random access preamble. If two-step RACH transmission is supported, the resource configuration during random access also includes PUSCH resource configuration, also known as PUSCH Occasion (PO). In the two-step RACH, message A (MsgA) includes MsgA Preamble and MsgA PUSCH (Physical Uplink Shared Channel). RO is the time-frequency resource used to carry the MsgA Preamble, and PO is the time-frequency resource used to carry the MsgA PUSCH.

[0063] A key feature of NR systems is their support for downlink multi-beaming. Before communication between network devices and terminal devices, the network devices need to know the beam the terminal device is on in order to set the appropriate beam direction during subsequent data transmission. Because of the mapping relationship between SSBs and ROs, the terminal device can select the RO associated with the downlink receive beam to send PRACH or Msg A during the random access process. After detecting PRACH (Physical Random Access Channel) or Msg A, the network device can determine the appropriate downlink receive beam direction for the terminal device.

[0064] With the development of communication technology, research on 6G communication technology has begun. Considering the importance of network energy conservation, possible energy-saving solutions need to be considered from the initial design stage of 6G communication technology. However, in 6G networks, how to ensure that terminal devices can remain or access the network in energy-saving mode to guarantee their communication performance is a problem that needs to be solved.

[0065] Please refer to Figure 4, which shows a flowchart of a wireless communication method provided in an embodiment of this application, which is performed by a terminal device. The method includes the following step 410.

[0066] Step 410: The terminal device receives first information, which is used to determine the operating mode of the network device in the first cell. The operating mode includes a first mode and a second mode. In the first mode, the network device transmits a first channel or a set of signals. In the second mode, the network device transmits a second channel or a set of signals.

[0067] Accordingly, the network device sends the first message.

[0068] In some embodiments, the first information is used to directly or indirectly indicate the operating mode of the network devices in the first cell. In some embodiments, the operating mode of the network devices in the first cell may also be referred to as the operating mode of the first cell.

[0069] In some embodiments, the first channel or signal set and / or the second channel or signal set are used to transmit downlink control information and / or downlink data. In some embodiments, the information carried in the first channel or signal set and / or the second channel or signal set is also used to indicate resources for uplink channel or signal transmission.

[0070] In some embodiments, the first channel or signal set is different from the second channel or signal set.

[0071] In some embodiments, at least one channel or signal in the first channel or signal set is different from the channel or signal included in the second channel or signal set.

[0072] In some embodiments, at least one piece of information in the first channel or signal set is different from the information carried in the second channel or signal.

[0073] In some embodiments, the first channel or signal set is partially the same as the second channel or signal set.

[0074] In some embodiments, the channels or signals included in the first set of channels or signals are partially the same as those included in the second set of channels or signals. For example, the first set of channels or signals includes a third set of channels or signals, and the second set of channels or signals also includes the third set of channels or signals. Alternatively, the third set of channels or signals is a subset of the first set of channels or signals, and the third set of channels or signals is a subset of the second set of channels or signals.

[0075] In some embodiments, the information carried in the first channel or signal set is partially the same as the information carried in the second channel or signal set.

[0076] In some embodiments, the first set of channels or signals is a subset of the second set of channels or signals. In other words, channels or signals included in the first set of channels or signals are also included in the second set of channels or signals, while channels or signals included in the second set of channels or signals are not necessarily included in the first set of channels or signals.

[0077] In some embodiments, the information carried in the first channel or signal set is a subset of the information carried in the second channel or signal set.

[0078] In some embodiments, the network device determines its operating mode based on the data transmission between it and the terminal device. For example, if no data transmission is required between the network device and the terminal device for a period of time, the network device can enter a first mode; if data transmission or signaling exchange is required between the network device and the terminal device for a period of time, the network device can enter a second mode.

[0079] In some embodiments, the network device determines its operating mode based on the number of terminal devices residing in the first cell. For example, when there are few terminal devices residing in the first cell, the network device enters a first mode; when there are many terminal devices residing in the first cell, the network device enters a second mode. The network device may make this determination based on a preset threshold.

[0080] In some embodiments, a network device notifies other network devices of its current operating mode through an interface for interaction between network devices. For example, a network device notifies other network devices of its current operating mode through the Xn interface.

[0081] In some embodiments, the first information may be one or more of the following: a synchronization signal or a synchronization signal block, a system message, a paging message, or a terminal device-specific configuration message. The first information may be the same or different in different operating modes. For example, in a first mode, the first information may be a synchronization signal or a synchronization signal block; in a second mode, the first information may be a system message.

[0082] In some embodiments, the first information is used to determine the operating mode of the network device in the first cell, including: the first information is used to indicate that the operating mode of the network device in the first cell is a first mode or a second mode, wherein the first information is one or more of the following: a synchronization signal or a synchronization signal block, a first part of a system message.

[0083] In some embodiments, the first mode includes at least one of the following: a first sub-mode, a second sub-mode, and a third sub-mode. First information is used to determine the operating mode of the network device in the first cell, including: the first information indicating that the operating mode of the network device in the first cell is one of the first sub-mode, the second sub-mode, and the third sub-mode, wherein the first information is one or more of the following: a synchronization signal or a synchronization signal block, and a first part of a system message.

[0084] In some embodiments, the first information is used to determine the operating mode of the network device in the first cell as one of the following modes: a first sub-mode, a second sub-mode, and a third sub-mode; wherein the first information is at least one of the following: a synchronization signal or a synchronization signal block, a first part of a system message, and a second part of a system message; the first part of the system message is used to indicate basic information for accessing the first cell, and the second part of the system message is used to indicate relevant information for mobility management.

[0085] In some embodiments, in a first sub-mode, the first channel or signal set is used for the terminal device to discover a first cell; in a second sub-mode, the first channel or signal set is used for the terminal device to camp in the first cell; and in a third sub-mode, the first channel or signal set is used for the terminal device to camp in the first cell and listen for paging messages.

[0086] In some embodiments, the second mode includes at least one of the following: a fourth sub-mode, a fifth sub-mode, and a sixth sub-mode. The first information is used to determine the operating mode of the network device in the first cell, including: the first information indicating that the operating mode of the network device in the first cell is one of the fourth sub-mode, the fifth sub-mode, and the sixth sub-mode, wherein the first information is a second part of the system message.

[0087] In some embodiments, the first information is used to determine the operating mode of the network device in the first cell as one of the following modes: a fourth sub-mode, a fifth sub-mode, and a sixth sub-mode; wherein the first information is at least one of the following: a synchronization signal or a synchronization signal block, a first part of a system message, a second part of a system message, a third part of a system message, and a proprietary configuration message of the terminal device; the first part of the system message is used to indicate basic information for accessing the first cell, the second part of the system message is used to indicate relevant information for mobility management, and the third part of the system message is used to indicate relevant information for paging.

[0088] In some embodiments, in the fourth sub-mode, the network device transmits a second channel or signal set; in the fifth sub-mode, the network device transmits a second channel or signal set during the operation of a first timer; and in the sixth sub-mode, the network device transmits a second channel or signal set during a first configuration enable period.

[0089] In some embodiments, the information used to indicate the operating mode of the first cell and the information used to indicate which specific sub-mode the first cell's operating mode is may be the same information or different information. For example, the network device may indicate that the first cell's operating mode is a first mode or a second mode via a synchronization signal, a synchronization signal block, or a first part of a system message. When the operating mode is the first mode, if the first mode includes multiple sub-modes, the synchronization signal, synchronization signal block, or first part of a system message may indicate which sub-mode of the first mode the first cell's operating mode is. When the operating mode is the second mode, if the second mode includes multiple sub-modes, the synchronization signal, synchronization signal block, first part of a system message, or second part of a system message may indicate which sub-mode of the second mode the first cell's operating mode is. For example, the synchronization signal or synchronization signal block indicates that the first cell's operating mode is a first sub-mode within a first mode. As another example, if the synchronization signal or synchronization signal block indicates that the first cell's operating mode is the first mode, the first part of a system message indicates that the first cell's operating mode is a first sub-mode. For example, the synchronization signal or synchronization signal block indicates that the first cell's operating mode is a third sub-mode within a second mode. For example, if the first part of the system message indicates that the first cell is operating in the second mode, the second part of the system message indicates that the first cell is operating in the third sub-mode.

[0090] In some embodiments, a system message may include multiple parts, each of which carries a different function.

[0091] In some embodiments, the information carried in the first channel or signal set includes at least one of the following:

[0092] Synchronization signal or synchronization signal block;

[0093] The first part of the system messages is used to indicate the basic information for accessing the first cell;

[0094] The second part of the system messages is used to indicate information related to mobility management;

[0095] The third part of the system message is used to indicate relevant information about paging.

[0096] In some embodiments, in a first mode, information carried in a first channel or signal set is used to indicate a first uplink resource, the first uplink resource is used to transmit second information, and the second information is used to request the network device to transmit a system message.

[0097] In some embodiments, the information carried in the second channel or signal set includes at least one of the following:

[0098] Synchronization signal or synchronization signal block;

[0102] The fourth part, system messages, is used to indicate relevant information for uplink access.

[0103] In some embodiments, the information carried in the second channel or signal set includes:

[0104] Synchronization signal or synchronization signal block;

[0105] The first part of the system messages is used to indicate the basic information for accessing the first cell;

[0106] The second part of the system messages is used to indicate information related to mobility management;

[0107] The third part of the system message is used to indicate relevant information about paging;

[0108] The fourth part, system messages, is used to indicate relevant information for uplink access.

[0110] In some embodiments, the synchronization signal block includes a synchronization signal and a first portion of system messages. Alternatively, the channel or signal set consisting of the synchronization signal and the first portion of system messages can be replaced by the synchronization signal block. Exemplarily, the information carried in the first channel or signal set includes the synchronization signal, the first portion of system messages, and the second portion of system messages; or the information carried in the first channel or signal set includes the synchronization signal block and the second portion of system messages.

[0111] In some embodiments, the information carried in the synchronization signal block is different from the information carried in the first part of the system message.

[0112] In some embodiments, the information carried in the first channel or signal set includes a synchronization signal or a synchronization signal block, which can be understood as: the first channel or signal set includes a synchronization signal or a synchronization signal block. Similarly, the information carried in the second channel or signal set includes a synchronization signal or a synchronization signal block, which can be understood as: the second channel or signal set includes a synchronization signal or a synchronization signal block.

[0113] In some embodiments, the information carried in the first channel or signal set includes system messages, which can be understood as: the channels or signals included in the first channel or signal set are used to transmit system messages.

The system messages include at least one of the following: a first part of system messages, a second part of system messages, a third part of system messages, and a fourth part of system messages.

[0114] In some embodiments, the first mode is an energy-saving mode, and the second mode is a normal mode. In some embodiments, network devices in the first mode are more energy-efficient and consume less power than network devices in the second mode.

[0115] The technical solution provided in this application provides network devices with two different operating modes. In these two modes, the network devices transmit different channels or signal sets, allowing the network devices to adjust their operating mode. For example, when data transmission demand is low, the network device adopts a more energy-efficient operating mode; when data transmission demand is high, the network device adopts a more comprehensive operating mode. This is beneficial for power saving and also ensures the communication performance between the network device and the terminal device.

[0116] In some embodiments, a system message may include multiple parts, each carrying a different function. System messages transmitted by network devices in different operating modes may be the same or different. This application provides a method for dividing system messages into different parts.

[0117] In some embodiments, the system message includes: a first part of the system message, a second part of the system message, a third part of the system message, and a fourth part of the system message.

[0118] 1. First part: System messages

[0136] In some embodiments, if the first part of the system message is used to determine that the terminal device is not allowed to access the first cell or the cell group to which the first cell belongs, the terminal device should attempt to search for other frequency points to access other cells or cell groups. For example, if the first part of the system message includes information indicating the frequency point of a cell in the second mode, the terminal device can search based on the frequency points provided by that information to select a cell in the second mode for access. For example, if the first part of the system message includes information indicating the frequency point of a cell in the first mode, the terminal device can search based on the frequency points provided by that information to select other cells in the first mode for access.

[0137] 2. Part Two: System Messages

[0154] 4. Part Four: System Messages

[0155] In some embodiments, the fourth part of the system message is used to indicate information related to uplink access.

[0156] In some embodiments, the fourth part of the system message is used to determine at least one of the following:

[0160] In some embodiments, the fourth part of the system message is used to indicate uplink access-related configuration information, such as RACH configuration information.

[0161] In some embodiments, system messages can also be divided in other ways. For example, system messages can be divided according to their transmission method. For instance, system messages can be divided into three parts based on whether they are transmitted via broadcast, unicast, or multicast.

[0162] By using the above method, system messages are divided into multiple parts. In different scenarios, network devices can send only all or part of the system messages to reduce the power consumption of network devices, while still meeting the communication needs between terminal devices and network devices.

[0163] In some embodiments, to be applicable to more scenarios, different sub-modes can be set for the two working modes respectively, so that the network device can balance power saving and communication performance.

[0164] I. First Mode

[0165] In some embodiments, the first mode includes at least one of the following: a first sub-mode, a second sub-mode, and a third sub-mode.

[0166] In some embodiments, in the first mode, the method further includes step 420.

[0167] Step 420: The terminal device sends second information through the first uplink resource. The second information is used to request the network device to transmit system messages.

[0168] Accordingly, the network device receives the second information through the first uplink resource.

[0169] In some embodiments, the first uplink resource is pre-configured.

[0170] In some embodiments, the configuration information of the first uplink resource is carried by at least one of the following: a synchronization signal or a synchronization signal block, and a first part of a system message, wherein the first part of the system message is used to indicate basic information for accessing the first cell.

[0171] In some embodiments, the configuration information of the first uplink resource is transmitted through the second cell.

[0172] The first, second, and third sub-patterns will be introduced next.

[0173] 1. First Sub-pattern

[0174] In some embodiments, in the first sub-mode, the first channel or signal set is used by the terminal device to discover the first cell.

[0175] In some embodiments, the information carried in the first channel or signal set includes a synchronization signal or a synchronization signal block, and in the first sub-mode, the first channel or signal set also carries a first portion of system messages.

[0176] In some embodiments, in the first sub-mode, the second information is used to request the network device to transmit at least one of the following system messages: a second part system message, a third part system message, and a fourth part system message; wherein the second part system message is used to indicate mobility management related information, the third part system message is used to indicate paging related information, and the fourth part system message is used to indicate uplink access related information.

[0177] For example, when the terminal device decides to camp in the first cell, the second information is used to request the network device to transmit the second part of the system message; when the terminal device decides to receive a paging message in the first cell, the second information is used to request the network device to transmit the third part of the system message; when the terminal device decides to transmit data in the first cell, the second information is used to request the network device to transmit the fourth part of the system message.

[0178] In some embodiments, in the first sub-mode, the first part of the system message is not used to determine the configuration information of the second part of the system message.

[0179] In some embodiments, the second information indicates the type of system message requested by the second information in an implicit or explicit manner.

[0180] In some embodiments, the second information includes at least one bit indicating the type of system message requested by the second information. For example, the second information uses three bits to indicate the type of system message requested by the second information. For example, as shown in Table 1:

[0181] Table 1: System messages transmitted in the second information request in the first sub-mode

[0182] In some embodiments, the type of system message requested by the second information is associated with the first uplink resource occupied by the second information.

[0183] For example, the information carried in the first channel or signal set is used to indicate multiple first uplink resources, wherein first uplink resource 1 is associated with a second part of the system message, first uplink resource 2 is associated with a third part of the system message, and first uplink resource 3 is associated with a fourth part of the system message. After determining the type of system message to be transmitted by the network device, the terminal device selects an appropriate first uplink resource to send the second information.

[0184] In some embodiments, after receiving the second information, the network device may send one or more of the following messages to the terminal device: a system message confirming that the terminal device's request has been sent, a system message confirming that the terminal device's request has not been sent, or a system message confirming that the terminal device's request has been sent.

[0185] In some embodiments, after the terminal device sends the second information to the network device, the resources of the control channel are determined by the configuration information of the control channel, and the network device is monitored for confirmation of transmission of system messages or whether the network device transmits system messages by monitoring the resources of the control channel.

[0186] For example, Figure 5 shows an example diagram of the first cell in the first sub-mode scenario. The network device sends a synchronization signal and a first part of the system message (denoted as System Message 1), and reserves uplink on-demand resources (first uplink resources). When the terminal device listens to the synchronization signal and System Message 1, the terminal device can determine that the first cell is in the first sub-mode scenario, and can send second information according to the on-demand resources configured in System Message 1. This second information is used to request the network device to send a second part of the system message (denoted as System Message 2). After receiving the second information from the terminal device, the network device sends an indication to confirm the transmission of the system message and / or control information to schedule the transmission of System Message 2 through the resources of the control channel configured in System Message 1. After sending the second information, the terminal device listens to whether the network device confirms the indication to transmit the system message and / or schedules the transmission of System Message 2 through the resources of the control channel configured in System Message 1.

[0187] 2. Second Sub-pattern

[0188] In some embodiments, in the second sub-mode, the first channel or signal set is used for the terminal device to camp in the first cell.

[0189] In some embodiments, the information carried in the first channel or signal set includes a synchronization signal or a synchronization signal block. In the second sub-mode, the first channel or signal set also carries a first part of system messages and a second part of system messages.

[0190] In some embodiments, in the second sub-mode, the second information is used to request the network device to transmit at least one of the following system messages: a third part system message and a fourth part system message; wherein the third part system message is used to indicate paging-related information, and the fourth part system message is used to indicate uplink access-related information.

[0191] In some embodiments, in the second sub-mode, the second part of the system message is not used to determine the configuration information of the third part of the system message.

[0192] In some embodiments, the second information indicates the type of system message requested by the second information in an implicit or explicit manner.

[0193] In some embodiments, the second information includes at least one bit indicating the type of system message requested by the second information. For example, the second information uses two bits to indicate the type of system message requested by the second information. For example, as shown in Table 2:

[0194] Table 2: System messages transmitted in the second information request in the second sub-mode

[0195] In some embodiments, the type of system message requested by the second information is associated with the first uplink resource occupied by the second information.

[0196] For example, the information carried in the first channel or signal set is used to indicate multiple first uplink resources, wherein first uplink resource 1 is associated with the third part of the system message, and first uplink resource 2 is associated with the fourth part of the system message. After determining the type of system message to be transmitted by the network device, the terminal device selects an appropriate first uplink resource to send the second information.

[0197] In some embodiments, after receiving the second information, the network device may send one or more of the following messages to the terminal device: a system message confirming that the terminal device's request has been sent, a system message confirming that the terminal device's request has not been sent, or a system message confirming that the terminal device's request has been sent.

[0198] In some embodiments, after the terminal device sends the second information to the network device, the resources of the control channel are determined by the configuration information of the control channel, and the network device is monitored for confirmation of transmission of system messages or whether the network device transmits system messages by monitoring the resources of the control channel.

[0199] For example, Figure 6 shows an example diagram of the first cell in a second sub-mode scenario. The network device sends a synchronization signal, a first part of the system message (denoted as System Message 1), and a second part of the system message (denoted as System Message 2), and reserves uplink on-demand resources (first uplink resources). When the terminal device listens to the synchronization signal, System Message 1, and System Message 2, the terminal device can determine that the first cell is in a second sub-mode scenario, and can send second information according to the on-demand resources configured in System Message 1 or System Message 2. This second information is used to request the network device to send a third part of the system message (denoted as System Message 3). After receiving the second information from the terminal device, the network device sends an indication to confirm the transmission of the system message and / or control information to schedule the transmission of System Message 3 through the control channel resources configured in System Message 1 or System Message 2. After sending the second information, the terminal device listens to whether the network device confirms the indication to confirm the transmission of the system message and / or schedules the transmission of System Message 3 through the control channel resources configured in System Message 1 or System Message 2.

[0200] 3. Third Sub-pattern

[0201] In some embodiments, under the third sub-mode, the first channel or signal set is used for the terminal device to camp on the first cell and receive paging messages.

[0202] In some embodiments, the information carried in the first channel or signal set includes a synchronization signal or a synchronization signal block, and the first channel or signal set also carries a first part of system messages, a second part of system messages, and a third part of system messages.

[0203] In some embodiments, under the third sub-mode, the second information is used to request the network device to transmit a fourth part of the system message, which is used to indicate relevant information for uplink access.

[0204] In some embodiments, under the third sub-mode, the third part of the system message is not used to determine the configuration information of the fourth part of the system message.

[0205] In some embodiments, the second information indicates the type of system message requested by the second information in an implicit or explicit manner. For example, when a terminal device sends the second information, the second information indicates a request for the network device to transmit a fourth part of the system message.

[0206] In some embodiments, the second information includes at least one bit used to indicate the type of system message requested by the second information. Exemplarily, the second information uses one bit to indicate the type of system message requested. For example, 1 indicates that the system message type requested by the second information is a fourth-part system message, and 0 is a reserved bit. Exemplarily, the second information uses one bit to indicate whether the second information is used to request the network device to transmit a fourth-part system message. For example, 1 indicates a request for the network device to transmit a fourth-part system message.

[0207] In some embodiments, the type of system message requested by the second information is associated with the first uplink resource occupied by the second information.

[0208] For example, a first channel or signal set is used to indicate multiple first uplink resources, wherein the first uplink resource 1 is associated with the fourth part of the system message. After determining the type of system message to be transmitted by the network device, the terminal device selects an appropriate first uplink resource to send the second information.

[0209] In some embodiments, under the third sub-mode, the system message type requested by the second information defaults to the fourth part system message.

[0210] In some embodiments, after the network device receives the second information, it may send one or more of the following information to the terminal device: confirming the sending of the fourth part of the system message, confirming not to send the fourth part of the system message, or sending the fourth part of the system message.

[0211] In some embodiments, after the terminal device sends the second information to the network device, the resources of the control channel are determined by the configuration information of the control channel, and the network device is monitored by the resources of the control channel to see whether the network device confirms the transmission of the fourth part of the system message or whether the network device transmits the fourth part of the system message.

[0212] For example, Figure 7 shows an example diagram of the first cell in a third sub-mode scenario. The network device sends a synchronization signal, a first part of the system message (denoted as system message 1), a second part of the system message (denoted as system message 2), and a third part of the system message (denoted as system message 3), and reserves uplink on-demand resources (first uplink resources). When the terminal device listens to the synchronization signal, system message 1, system message 2, and system message 3, the terminal device can determine that the first cell is in a third sub-mode scenario, and can send second information according to the on-demand resources configured in system message 1, system message 2, or system message 3. This second information is used to request the network device to send a fourth part of the system message (denoted as system message 4). After receiving the second information from the terminal device, the network device sends an indication to confirm the transmission of the fourth part of the system message and / or control information to schedule the transmission of system message 4 through the resources of the control channel configured in system message 1, system message 2, or system message 3. After sending the second information, the terminal device checks whether the resource monitoring network device configured by the control channel of system message 1, system message 2, or system message 3 confirms the instruction to transmit the fourth part of the system message and / or the control information to be transmitted by the scheduling system message 4.

[0213] II. Second Mode

[0214] In some embodiments, the second mode includes at least one of the following: a fourth sub-mode, a fifth sub-mode, and a sixth sub-mode.

[0215] In some embodiments, in the second mode, the first uplink resource is not included in the first cell.

[0216] In some embodiments, in the second mode, the first part of the system message is not used to determine the configuration information of the first uplink resource, the first uplink resource is used to transmit the second information, the second information is used to request the network device to transmit the system message, and the first part of the system message is used to indicate the basic information for accessing the first cell.

[0217] In other words, in the second mode, the second channel or signal set can include comprehensive system messages, and the terminal device no longer needs to send a second message to the network device to request the transmission of system messages.

[0218] The fourth, fifth, and sixth sub-patterns will be introduced next.

[0219] 1. Fourth Sub-pattern

[0220] In some embodiments, in the fourth sub-mode, the network device transmits a second channel or set of signals.

[0221] In some embodiments, in the fourth sub-mode, the second channel or signal set includes common channels or signals required for the normal operation of the first cell. Exemplarily, the second channel or signal set includes a synchronization signal or synchronization signal block, a first part of system messages, a second part of system messages, a third part of system messages, and a fourth part of system messages. Exemplarily, the second channel or signal set includes a synchronization signal block, a second part of system messages, a third part of system messages, and a fourth part of system messages.

[0222] In some embodiments, under the fourth sub-mode, the information carried in the second channel or signal set does not include the configuration information of the first uplink resource. That is, the terminal device can discover the first cell, camp in the first cell, receive paging messages in the first cell, and perform uplink access in the first cell based on the second channel or signal set sent by the network, without needing to request transmission system messages from the network device.

[0223] For example, Figure 8 shows an example diagram of the first cell in the fourth sub-mode scenario. The network device sends a synchronization signal, a first part of the system message (denoted as system message 1), a second part of the system message (denoted as system message 2), a third part of the system message (denoted as system message 3), and a fourth part of the system message (denoted as system message 4). When the terminal device listens to the synchronization signal, system message 1, system message 2, system message 3, and system message 4, the terminal device can discover the first cell based on system message 1, or camp in the first cell based on system message 2, or receive paging information in the first cell based on system message 3, or perform uplink access in the first cell based on system message 4.

[0224] 2. Fifth Sub-pattern

[0225] In some embodiments, in the fifth sub-mode, the network device transmits a second channel or set of signals during the operation of the first timer.

[0226] In some embodiments, the network device does not transmit a second channel or signal set after the first timer has finished running.

[0227] In some embodiments, in the fifth sub-mode, the second channel or signal set includes common channels or signals required for the normal operation of the first cell. Exemplarily, the second channel or signal set includes a synchronization signal or synchronization signal block, a first part of system messages, a second part of system messages, a third part of system messages, and a fourth part of system messages. Exemplarily, the second channel or signal set includes a synchronization signal block, a second part of system messages, a third part of system messages, and a fourth part of system messages.

[0228] In some embodiments, under the fifth sub-mode, the information carried in the second channel or signal set does not include the configuration information of the first uplink resource. That is, the terminal device can discover the first cell, camp in the first cell, receive paging messages in the first cell, and perform uplink access in the first cell based on the second channel or signal set sent by the network, without needing to request transmission system messages from the network device.

[0229] In some embodiments, in the fifth sub-mode, the method further includes at least one of the following steps 430 to 440.

[0230] Step 430: The terminal device receives the third information.

[0231] Step 440: Upon receiving the third information, the terminal device starts or restarts the first timer.

[0232] Accordingly, the network device sends third information.

[0233] In some embodiments, the third information is used to determine whether to start or restart the first timer.

[0234] In some embodiments, the third information is used to indicate whether to start or restart the first timer.

[0235] In some embodiments, the third information may explicitly or implicitly indicate the start or restart of the first timer.

[0236] In some embodiments, the network device configures a first timer and determines the effective time for the transmission of the second channel or signal set by starting or restarting the first timer.

[0237] In some embodiments, in the fifth sub-mode, the behavior of the terminal device includes at least one of the following:

[0238] The terminal device assumes that the first cell will be shut down after the first timer finishes running;

[0239] The terminal device assumes that the network device in the first cell switches to the first mode after the first timer finishes running;

[0240] The terminal device assumes that the network device in the first cell transmits the first channel or signal set after the first timer finishes running;

[0241] Receive the fourth information, which is used to instruct the terminal device to switch from the first cell to another cell;

[0242] Receive the fifth message, which indicates at least one of the following: the terminal device is not camped in the first cell, or the terminal device is not listening for paging messages in the first cell.

[0243] Accordingly, in the fifth submode, the network device's behavior includes at least one of the following:

[0244] The first cell is shut down after the first timer finishes running;

[0245] The network devices in the first cell switch to the first mode after the first timer finishes running;

[0246] The network devices in the first cell transmit the first channel or signal set after the first timer finishes running;

[0247] Send the fourth message;

[0248] Send the fifth message.

[0249] In some embodiments, after the effective time expires (e.g., the timer expires), the network device can hand over all terminal devices in the first cell to other cells. In some embodiments, after the first timer finishes running, the terminal device receives fourth information, which instructs the terminal device to perform a cell handover or to hand over to a third cell. In some embodiments, the network device can send the fourth information to the terminal device, indicating the third cell to which the terminal device wants to hand over. Alternatively, the network device can send the fourth information to the terminal device, instructing the terminal device to perform a cell handover, wherein the third cell to which the terminal device wants to hand over is determined by the terminal device itself or directly indicated by the network device.

[0250] In some embodiments, after the effective time expires, the network device may switch the first cell to the first mode or shut down the first cell. In some embodiments, after the first timer finishes running, the operating mode of the first cell is switched to the first mode, or the first cell is shut down. In some embodiments, after the first timer finishes running, the operating mode of the first cell is switched to the first sub-mode, the second sub-mode, or the third sub-mode, or the first cell is shut down.

[0251] In some embodiments, after the effective time expires (e.g., the timer expires), the network device no longer transmits the second channel or signal set. In some embodiments, if the network device instructs the first timer to be restarted during the operation of the first timer, the operation time of the first timer restarts from the restart time.

[0252] For example, Figure 9 shows an example diagram of the first cell in the fifth sub-mode scenario. During the validity period of the first timer, the network device sends a synchronization signal, a first part of the system message (denoted as system message 1), a second part of the system message (denoted as system message 2), a third part of the system message (denoted as system message 3), and a fourth part of the system message (denoted as system message 4). After the first timer expires, the network device switches the first cell to the first sub-mode, sends a synchronization signal and the first part of the system message (denoted as system message 1), and reserves uplink on-demand resources (first uplink resources).

[0253] 3. Sixth Sub-pattern

[0254] In some embodiments, in the sixth sub-mode, the second channel or signal set is transmitted during the first configuration activation period.

[0255] In some embodiments, under the sixth sub-mode, step 410 above is implemented as step 411 below.

[0256] Step 411: During the first configuration activation period, the terminal device receives the first information.

[0257] Accordingly, during the first configuration activation period, the network device sends the first information.

[0258] In some embodiments, in the sixth sub-mode, the second channel or signal set includes common channels or signals required for the normal operation of the first cell. Exemplarily, the second channel or signal set includes a synchronization signal or synchronization signal block, a first part of system messages, a second part of system messages, a third part of system messages, and a fourth part of system messages. Exemplarily, the second channel or signal set includes a synchronization signal block, a second part of system messages, a third part of system messages, and a fourth part of system messages.

[0259] In some embodiments, under the sixth sub-mode, the information carried in the second channel or signal set does not include the configuration information of the first uplink resource. That is, the terminal device can discover the first cell, camp in the first cell, receive paging messages in the first cell, and perform uplink access in the first cell based on the second channel or signal set sent by the network, without needing to request transmission system messages from the network device.

[0260] In some embodiments, under the sixth sub-mode, the network device does not transmit the second channel or signal set during the first configuration shutdown period.

[0261] In some embodiments, under the sixth sub-mode, the network device does not transmit the first channel or signal set during the first configuration off period. Exemplarily, the network device transmits the second channel or signal set during the first configuration on period, and neither transmits the second channel or signal set nor the first channel or signal set during the first configuration off period.

[0262] In some embodiments, in the sixth sub-mode, the network device transmits a first channel or signal set during a first configuration off period. Exemplarily, the network device transmits a second channel or signal set during a first configuration on period and transmits the first channel or signal set during a first configuration off period.

[0263] In some embodiments, the first configuration is a cellDTRX (Cell Discontinuous Transmission and / or Cell Discontinuous Reception) configuration.

[0264] In some embodiments, the network device transmits a second channel or set of signals during the cellDTRX configuration enabled period.

[0265] In some embodiments, the network device does not transmit a second channel or signal set during the cellDTRX configuration shutdown period.

[0266] In some embodiments, the network device does not transmit the first channel or signal set during the cellDTRX configuration off period. Exemplarily, the network device transmits the second channel or signal set during the cellDTRX configuration on period, and neither transmits the second channel or signal set nor the first channel or signal set during the cellDTRX configuration off period.

[0267] In some embodiments, the network device transmits a first channel or set of signals during a cellDTRX configuration off period. Exemplarily, the network device transmits a second channel or set of signals during a cellDTRX configuration on period and transmits the first channel or set of signals during a cellDTRX configuration off period.

[0268] In some embodiments, the first cell remains in the sixth sub-mode during the first configuration shutdown period.

[0269] In some embodiments, during the first configuration shutdown period, the first cell switches to the first mode (or one of the first sub-mode, the second sub-mode, and the third sub-mode), and during the first configuration re-enable period, the first cell switches back to the sixth sub-mode.

[0270] For example, Figure 10 shows an example diagram of the first cell in the sixth sub-mode scenario. During the cellDTRX enabled period, the network device sends a synchronization signal, a first part of the system message (referred to as system message 1), a second part of the system message (referred to as system message 2), a third part of the system message (referred to as system message 3), and a fourth part of the system message (referred to as system message 4). During the cellDTRX disabled period, the network device does not send the synchronization signal, the first part of the system message (referred to as system message 1), the second part of the system message (referred to as system message 2), the third part of the system message (referred to as system message 3), and the fourth part of the system message (referred to as system message 4).

[0271] III. The first mode and the second mode can be switched between each other.

[0272] In some embodiments, the operating mode of the network devices in the first cell can switch between a first mode and a second mode.

[0273] In some embodiments, the operating mode of the first cell can switch between a first mode and a second mode.

[0274] In some embodiments, the operating modes of network devices in the first cell can be switched between each other in the following operating modes: first sub-mode, second sub-mode, third sub-mode, fourth sub-mode, fifth sub-mode and sixth sub-mode.

[0275] In some embodiments, the operating mode of the network device in the first cell can be switched from the fifth sub-mode to the first sub-mode, the second sub-mode, or the third sub-mode, while the fourth and sixth sub-modes cannot be switched to the first sub-mode, the second sub-mode, or the third sub-mode.

[0276] For example, as shown in Figure 11, the operating mode of the network device in the first cell can switch between the first sub-mode, the second sub-mode, and the third sub-mode, or between the first sub-mode, the second sub-mode, the third sub-mode, and the fifth sub-mode, or between the fourth sub-mode, the fifth sub-mode, and the sixth sub-mode.

[0277] The above method provides six possible operating modes. When there are few terminal devices in the first cell, the network device can operate in the first mode or one of the three sub-modes within the first mode. When there are many terminal devices in the first cell, the network device can operate in the second mode or one of the three sub-modes within the second mode. This allows the network device to avoid continuously sending system messages when there are few terminal devices in the first cell, saving power. Conversely, it can continuously send system messages when there are many terminal devices in the first cell, improving the efficiency of the communication system. The network device can switch between the first and second modes to achieve a balance between network energy saving and communication system operating efficiency.
