[0041] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0042] FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

[0043] As shown in FIG. 1, the communication system 100 can include a terminal device 110 (or a communication terminal device) and a network device 120. The network device 120 can communicate with the terminal device 110 through an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0044] It should be understood that the communication system 100 is only exemplarily described in the embodiments of the present application, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), an Internet of Things (IoT) system, a Narrow Band Internet of Things (NB-IoT) system, an enhanced Machine-Type Communications (eMTC) system, a 5G communication system (also referred to as a New Radio (NR) communication system), or a future communication system, etc.

[0045] In the communication system 100 shown in FIG. 1, the network device 120 can be an access network device that communicates with the terminal device 110. The access network device can provide communication coverage for a specific geographic area and can communicate with the terminal device 110 (for example, a UE) located in the coverage area.

[0051] 3GPP is studying NTN technology, which generally uses satellite communication to provide communication services to ground users. Compared with ground cellular network communication, satellite communication has many unique advantages. First, satellite communication is not limited by the user's region. For example, general terrestrial communication cannot cover oceans, mountains, deserts and other areas where communication equipment cannot be set up or where communication coverage is not provided due to sparse population. For satellite communication, a satellite can cover a large area of the ground, and the satellite can orbit the earth, so theoretically every corner of the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor countries or regions at a low cost, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting the development of these areas. Third, satellite communication has a long distance, and the cost of communication does not increase significantly as the communication distance increases. Finally, satellite communication has high stability and is not limited by natural disasters.

[0052] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with an NR system to form an NR-NTN system. For another example, NTN technology can be combined with an Internet of Things (IoT) system to form an IoT-NTN system. As an example, the IoT-NTN system can include an NB-IoT-NTN system and an eMTC-NTN system.

In other words, one satellite beam can cover a ground area with a diameter of dozens to hundreds of kilometers to ensure the coverage of the satellite and improve the system capacity of the entire satellite communication system.

[0061] For the convenience of understanding the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows, which can be combined with the technical solutions of the embodiments of the present application in any manner as optional solutions, and all belong to the protection scope of the embodiments of the present application.

[0062] NES is of great significance to environmental sustainability, reducing the impact on the environment (reducing greenhouse gas emissions), and saving operating costs. Energy consumption has become a key part of the OPEX of operators. Most of the energy consumption comes from the wireless access network, more specifically, from the AAU, with a small share of data centers and fiber transmission. The power consumption of a wireless access can be divided into two parts: the dynamic part only includes the power consumption when data is being transmitted or received; the static part includes the power consumption necessary for the operation of maintaining the wireless access equipment at all times, including the power consumption when no data is being transmitted or received.

[0063] With the development of communication technology and the evolution of communication systems, energy consumption has gradually become an important indicator of the operation efficiency of communication systems.

[0064] In the NR system, the initial access process of the terminal device can be completed by detecting a synchronization signal block (Synchronization Signal / PBCH Block, SSB or SS / PBCH block) on a synchronization raster. The SSB is transmitted through a discovery signal transmission opportunity window or an SSB transmission opportunity window. The discovery signal transmission opportunity window or the SSB transmission opportunity window appears periodically, and the period can be configured by the network device through a high-level parameter. In the initial access process, the terminal device attempts to search for the SSB through the predefined possible time-frequency position of the SSB, and obtains time and frequency synchronization, radio frame timing, and cell ID through the detected SSB.

[0065] In addition to obtaining system timing information, the SSB index has another function, which is to indicate the quasi co-location (QCL) relationship between SSBs, or it can also be understood that the SSB index can indicate the beam direction. QCL means that the large-scale parameters experienced by the symbol on a certain antenna port can be inferred from the symbol on another antenna port. The large-scale parameters can include delay spread, average delay, Doppler spread, Doppler frequency shift, and spatial reception parameters. In the 5G NR system, different beams carrying SSBs form an SSB burst set, and different SSB indexes correspond to the time domain position information of different SSBs in the burst set, and also correspond to the specific SSB transmission beam information. SSBs with the same SSB index are 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; SSBs corresponding to different SSB indexes are not considered to have a QCL relationship because they may come from different transmission beams of the network device and experience different channel transmission characteristics.

[0066] After detecting the SSB, the terminal device can determine the configuration of the Type0- PDCCH CSS set through the master information block (MIB) message in the SSB. The terminal device can receive the scheduling of the network device for the system information block (SIB) 1 message through listening to the Type0-PDCCH CSS set. The MIB message and the SIB1 message both include system configuration information of the serving cell. Further, the terminal device can receive the scheduling of the network device for other system messages except the SIB1 message through listening to the Type0A-PDCCH CSS set, receive the scheduling of the network device for the paging message through listening to the Type2-PDCCH CSS set, and receive the paging early indication (PEI) information of the paging message sent by the network device through listening to the Type2A-PDCCH CSS set.

[0067] In the embodiments of the present application, the MIB can also be referred to as a master information block, and the SIB can also be referred to as a system information block.

[0068] The terminal device can also obtain resource configuration of a physical random access channel (PRACH) transmission opportunity (RO) in a random access procedure according to the system message SIB1 of the received cell. The RO is a time-frequency resource carrying a random access preamble (also referred to as PRACH). If two-step RACH transmission is supported, the resource configuration in the random access procedure also includes PUSCH resource configuration, also referred to as physical uplink shared channel (PUSCH) transmission opportunity (PO). Among them, the message A (MsgA) in the two-step RACH includes MsgA PRACH and MsgA PUSCH, the RO is a time-frequency resource for carrying MsgA PRACH, and the PO is a time-frequency resource for carrying MsgA PUSCH.

[0069] The characteristic of the NR system is to support downlink multi-beam, and different SSBs are associated with different beams. Before the terminal device initiates random access, the terminal device measures and evaluates the signal quality of the cell and the signal strength of each SSB in the cell. In the case that the SSB signal detection strength exceeds the threshold, the terminal device determines the SSB with the strongest or relatively strong signal, for example, the terminal device determines SSB#1 as the SSB with the strongest signal. The terminal device determines the PRACH transmission opportunity corresponding to the SSB#1 as RO#1 according to the mapping relationship between the SSB and the RO, and sends PRACH on the RO#1. If the network device successfully receives the PRACH, the network device can know the SSB selected by the terminal device based on the resource information of the successfully received PRACH, for example, the network device can determine that the PRACH is associated with the SSB#1 according to the association relationship, and thus can determine the beam information corresponding to subsequent communication according to the SSB#1.

[0070] In addition, the terminal device can also request the network device to send system messages according to the RO resource configured by the network device. The system messages requested by the terminal device to be sent by the network device can be other system messages in addition to SIB1, for example, SIB2, SIB3, SIB4, SIB5, SIB6, SIB7, SIB8, SIB9, SIB10, SIB11, SIB12, SIB13, SIB14, SIB15, SIB16, SIB17, SIB18, SIB19, SIB20, SIB21, etc.

[0071] With the development of communication technology, 6G communication technology has been studied at present. Considering the importance of network energy saving, possible network energy saving solutions need to be considered at the beginning of the design of 6G communication technology. However, the energy saving of network devices will cause the communication performance of terminal devices to decline, and how to balance between the two is a problem to be solved.

[0072] From the perspective of network energy saving, network devices should try to reduce the transmission of "always-on" channels or signals, so as to avoid possible meaningless energy consumption. However, the transmission of "always-on" channels or signals, such as SSB, SIB, Paging and other periodic public channel or signal transmission in 5G network, provides more opportunities for terminal devices to access the network, and if the transmission of these channels or signals is reduced, the performance of terminal devices will decline. Considering the compromise between the energy saving of network devices and the communication performance of terminal devices, in the 6G network, only the most basic channels or signals for guaranteeing the communication performance of terminal devices, such as SSB and Paging, can be reserved, and other public channels or signals can be transmitted on demand.

[0073] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0074] The wireless communication method provided by the embodiments of the present application, as shown in FIG. 4, is applied to a terminal device, and includes:

[0075] S401, the terminal device receives a first downlink channel or signal on a first time-frequency resource of a first cell, the first downlink channel or signal is used to determine a second time-frequency resource, and the second time-frequency resource is used to transmit a second downlink channel or signal, and the second downlink channel or signal is used to transmit a paging message.

[0076] In some embodiments, the first cell can be a serving cell or a searched cell of the terminal device. The terminal device receives the first downlink channel or signal on the first time-frequency resource of the first cell can be replaced by: the terminal device detects the first downlink channel or signal on the first time-frequency resource of the first cell.

[0077] In the embodiments of the present application, the resource used for transmitting the second downlink channel or signal can be determined according to the received first downlink channel or signal, wherein the second downlink channel or signal is used for transmitting a paging message. Through the above technical solution, the network device in the energy saving state can reduce the transmission of other unnecessary common channels or signals and only transmit the necessary paging message, so as to ensure the communication performance of the terminal device and achieve the purpose of energy saving. Correspondingly, the terminal device also only needs to monitor the paging message, thereby achieving the purpose of energy saving of the terminal device.

[0078] In some embodiments, the first downlink channel or signal includes a synchronization signal.

[0079] In some embodiments, in the case that the first downlink channel or signal includes a synchronization signal, the terminal device receiving the first downlink channel or signal on the first time-frequency resource of the first cell can be understood as that the terminal device receives the synchronization signal by blindly detecting the synchronization signal in the initial access process.

[0080] Here, the synchronization signal can be replaced by SSB or other descriptions.

[0081] In some embodiments, the first downlink channel or signal is used to carry one of the following: a master information block (MIB), a first system information block (SIB), the MIB and the first SIB.

[0084] In an example, the first SIB includes the most basic system configuration information in the first cell, wherein the most basic system configuration information in the first cell includes the paging configuration information of the first cell.

[0085] In an example, the relative position relationship between the synchronization signal and the first SIB is preset by a protocol. After detecting the synchronization signal, the terminal device can receive the first SIB according to the relative position relationship between the synchronization signal and the first SIB.

[0086] In an example, the first SIB is a minimum SIB, and the first downlink channel or signal is used to carry the MIB and / or the minimum SIB.

[0087] As an example, FIG. 5 shows a structure diagram of the first downlink channel or signal including SSB and minimum SIB. As shown in FIG. 5, the relative positions of SSB and minimum SIB in the time domain are determined, and the same frequency domain unit is occupied in the frequency domain. That is, after detecting the SSB, the terminal device can receive the minimum SIB according to the structure of the SSB and the minimum SIB. The network device does not need to use DCI to schedule the reception of the minimum SIB.

[0088] In some embodiments, the first downlink channel or signal is used to acquire one or more of the following: cell identity, system time information, downlink synchronization.

[0089] Correspondingly, the terminal device can acquire one or more of the following based on the first downlink channel or signal: cell identity, system time information, downlink synchronization.

[0090] As an example, the system time information can include the timing of a system time unit, such as: radio frame timing.

[0091] In the embodiments of the present application, the network device configures the paging-related configuration message in the system message block associated with the synchronization signal, so that the terminal device in the idle state can acquire the paging-related configuration when detecting the synchronization signal in the initial access process, thereby meeting the needs of the terminal device in the idle state to camp in the cell; at the same time, the network device can also reduce the transmission of meaningless system messages, achieving the purpose of network energy saving.

[0092] In some embodiments, the first downlink channel or signal is used to determine the second time-frequency resource, including:

[0093] The first indication information carried in the first downlink channel or signal is used to determine the second time-frequency resource.

[0096] In some embodiments, the first downlink channel or signal is used to carry the first SIB, and the first SIB includes the first indication information.

[0144] In some embodiments, the first downlink channel or signal and the second downlink channel or signal have a QCL relationship.

[0145] In the embodiments of the present application, the second downlink channel or signal is used to transmit a paging message, including one of the following:

[0146] The second downlink channel or signal is used to carry a first DCI (Downlink Control Information), and the first DCI is used to schedule transmission of the paging message.

[0147] The second downlink channel or signal is used to carry a second DCI, and the second DCI is used to indicate whether to receive the paging message.

[0148] The second downlink channel or signal is used to carry the paging message.

[0149] That is, the second downlink channel or signal used to transmit the paging message can include two cases:

[0150] Case one: the second downlink channel or signal includes a downlink control channel, and the second downlink channel or signal carries the first DCI or the second DCI. In the case where the second downlink channel or signal carries the first DCI, the first DCI is used to schedule transmission of the paging message, for example, to schedule a downlink shared channel carrying the paging message.

[0152] In some embodiments, which of the above cases the second downlink channel or signal used to transmit the paging message is protocol preset. For example, the protocol presets the way the second downlink channel or signal used to transmit the paging message as case one, that is, the second downlink channel or signal includes a downlink control channel. For another example, the protocol presets the way the second downlink channel or signal used to transmit the paging message as case two, that is, the second downlink channel or signal includes a downlink shared channel.

[0153] In some embodiments, which of the above cases the second downlink channel or signal used to transmit the paging message is determined according to the first downlink channel or signal. For example, the indication information carried in the first downlink channel or signal is used to indicate that the way the second downlink channel or signal used to transmit the paging message is case one or case two. For another example, the first downlink channel or signal can correspond to different scrambling codes, such as scrambling code A and scrambling code B. When the first downlink channel or signal corresponds to scrambling code A, it indicates that the way the second downlink channel or signal used to transmit the paging message is case one; or when the first downlink channel or signal corresponds to scrambling code B, it indicates that the way the second downlink channel or signal used to transmit the paging message is case two.

[0154] The above two cases are described below respectively.

[0198] In some embodiments, the scrambling code information corresponding to the first downlink channel or signal can be a scrambling code identifier or a sequence identifier used for transmission of the first downlink channel or signal.

[0199] In some embodiments, in a case where the second downlink channel or signal is used to carry the first DCI, the indication of listening to the second downlink channel or signal comprises: indicating receiving the paging message; and / or, the indication of not listening to the second downlink channel or signal or the indication of not listening to the second downlink channel or signal comprises: indicating not receiving the paging message or not indicating receiving the paging message.

The indication of not listening to the second downlink channel or signal can be replaced by: not indicating receiving the paging message.

[0201] In some embodiments, the time-frequency resource for transmitting the first DCI can be referred to as a paging occasion (PO).

[0202] For example, if the second downlink channel or signal is used to carry the first DCI, the second time-frequency resource for transmitting the second downlink channel or signal can be referred to as a PO, and accordingly, the terminal device listening to the second downlink channel or signal on the second time-frequency resource can be replaced by the terminal device listening to the first DCI on the PO.

[0203] In some embodiments, in the case where the second downlink channel or signal is used to carry the first DCI, the method further comprises:

[0204] In the case where the terminal device receives the first DCI on the second time-frequency resource, the terminal device receives the paging message according to the scheduling of the first DCI.

[0205] For example, the terminal device receives the first DCI on the second time-frequency resource, and the first DCI schedules the first PDSCH transmission, wherein the first PDSCH carries the paging message.

[0206] The following is an exemplary description of the scheme in which the second downlink channel or signal is used to carry the first DCI. As shown in FIG. 6 or FIG. 7, taking the first downlink channel or signal as an SSB and the second time-frequency resource as a PO as an example, the terminal device receives the SSB, and the SSB includes first indication information, wherein the first indication information is used to indicate the time domain position and the frequency domain position of the PO. The terminal device detects the SSB, and determines the position of the PO according to the first indication information in the SSB after receiving the SSB. The PO is used to transmit the first DCI, and the first DCI is used to schedule the first PDSCH carrying the paging message.

[0207] In an example, as shown in FIG. 6, the terminal device listens to the first DCI through the PO. If the terminal device receives the first DCI on the PO, the terminal device receives the first PDSCH according to the scheduling of the first DCI, and judges whether the first PDSCH carries the paging message of the terminal device after receiving the first PDSCH. If the terminal device does not detect the first DCI on the PO, the terminal device does not need to receive the first PDSCH.

[0208] In another example, the second indication information is further included in the SSB, and the second indication information is used to indicate whether the terminal device needs to monitor the first DCI on the PO. As shown in FIG. 6 or FIG. 7, the terminal device determines whether to monitor the first DCI on the PO according to the second indication information. When the second indication information indicates that the terminal device needs to monitor the first DCI on the PO, as shown in FIG. 6, the terminal device receives the first DCI on the PO, receives the first PDSCH according to the scheduling of the first DCI, and judges whether the first PDSCH carries the paging message of the terminal device after receiving the first PDSCH. When the second indication information indicates that the terminal device does not need to monitor the first DCI on the PO, as shown in FIG. 7, the terminal device does not monitor the first DCI on the PO.

[0211] In some embodiments, whether the second DCI carries the third indication information is used to indicate whether to receive the paging message.

[0212] In an example, when the third indication information is carried in the second downlink channel or signal, it indicates to receive the paging message; when the third indication information is not carried in the second downlink channel or signal, it indicates not to receive the paging message or does not indicate to receive the paging message.

[0213] In an example, when the third indication information is not carried in the second downlink channel or signal, it indicates to receive the paging message; when the third indication information is carried in the second downlink channel or signal, it indicates not to receive the paging message or does not indicate to receive the paging message.

[0214] In some embodiments, in the case where the second downlink channel or signal is used to carry the second DCI, the method further includes one or more of the following:

[0215] In the case where the second DCI is received on the second time-frequency resource and the third indication information indicates to receive the paging message, the terminal device monitors the third downlink channel or signal on a third time-frequency resource;

[0230] In some embodiments, the second downlink channel or signal is used to determine whether to monitor the third downlink channel or signal, which can be understood as: the second downlink channel or signal is used to indicate whether there is a third downlink channel or signal, or whether it is necessary to receive the third downlink channel or signal. Wherein, the second downlink channel or signal is used to determine to monitor the third downlink channel or signal, which can be understood as: the second downlink channel or signal is used to indicate that there is a third downlink channel or signal, or it is necessary to receive the third downlink channel or signal; the second downlink channel or signal is used to determine not to monitor the third downlink channel or signal, which can be understood as: the second downlink channel or signal is used to indicate that there is no third downlink channel or signal, or it is not necessary to receive the third downlink channel or signal.

[0295] In some embodiments, the method further comprises:

[0296] In a case where the terminal device receives the first DCI on the third time-frequency resource, the terminal device receives the paging message according to the scheduling of the first DCI.

[0297] That is, the terminal device performs monitoring of the third downlink channel or signal on the third time-frequency resource, and in a case where the third downlink channel or signal is received, the terminal device receives the paging message according to the scheduling of the first DCI carried by the third downlink channel or signal.

[0298] Exemplarily, the terminal device monitors the second DCI on the second time-frequency resource, i.e., PEI-O, the second DCI transmitted on the PEI-O carries third indication information, and the terminal device determines whether to monitor the first DCI on the third time-frequency resource, i.e., PO, according to the third indication information. If the third indication information indicates that the terminal device monitors the first DCI on the PO, the terminal device receives the first DCI transmitted on the PO through monitoring of the PO, wherein the first DCI is used for scheduling a first PDSCH carrying a paging message.

[0299] Next, a scheme in which the second downlink channel or signal is used to carry the second DCI is exemplarily described. As shown in FIG. 8 or FIG. 9, taking the first downlink channel or signal as an SSB, the second time-frequency resource as a PEI-O, and the third time-frequency resource as a PO as examples, the terminal device receives the SSB, and the SSB includes first indication information, wherein the first indication information is used to indicate the time domain position and the frequency domain position of the PEI-O. The terminal device detects the SSB, and after receiving the SSB, determines the PEI-O according to the first indication information in the SSB, and the PEI-O is used to transmit the second DCI. The terminal device monitors the second DCI on the PEI-O. Understandably, in some cases, after determining the information of the PEI-O, the terminal device can no longer receive the SSB, but monitors the second DCI on the PEI-O. The second DCI is used to indicate whether to receive a paging message, for example, the second DCI carries third indication information, and the third indication information is used to indicate whether to receive a paging message.

[0300] In the case where the second DCI indicates receiving the paging message, as shown in FIG. 8, the terminal device monitors the first DCI on the PO, receives the first PDSCH according to the scheduling of the first DCI, and judges whether the paging message of the terminal device is carried in the first PDSCH after receiving the first PDSCH. Or, in the case where the second DCI does not indicate receiving the paging message, as shown in FIG. 9, the terminal device does not monitor the first DCI on the PO.

[0301] In an example, the fourth indication information is included in the SSB, where the fourth indication information is used to indicate the time domain position and the frequency domain position of the PO.

[0302] In another example, the frequency domain position of the PO is the same as the frequency domain position of the PEI-O.

[0303] Case two: the second downlink channel or signal is used to carry the paging message

[0304] In some embodiments, the second downlink channel or signal is used to transmit the paging message, including:

[0305] The second downlink channel or signal is used to carry the paging message.

[0306] In some embodiments, the method further includes:

[0307] The terminal device receives the second downlink channel or signal on the second time-frequency resource.

[0308] In some embodiments, the first downlink channel or signal carries sixth indication information, where the sixth indication information is used to indicate whether to receive the second downlink channel or signal.

[0309] In some embodiments, the receiving the second downlink channel or signal on the second time-frequency resource includes one or more of the following:

[0310] In the case where the sixth indication information indicates receiving the second downlink channel or signal, the terminal device receives the second downlink channel or signal on the second time-frequency resource;

[0311] In the case where the sixth indication information indicates not receiving the second downlink channel or signal or in the case where the sixth indication information does not indicate receiving the second downlink channel or signal, the terminal device does not receive the second downlink channel or signal on the second time-frequency resource;

[0312] In the case where the first downlink channel or signal does not carry the sixth indication information, the terminal device receives the second downlink channel or signal on the second time-frequency resource.

[0313] In some embodiments, the receiving the second downlink channel or signal on the second time-frequency resource comprises: in a case where the sixth indication information is not carried in the first downlink channel or signal, the terminal device does not receive the second downlink channel or signal on the second time-frequency resource.

[0314] In some embodiments, the first downlink channel or signal corresponds to first scrambling code information or second scrambling code information, wherein the first scrambling code information is used to indicate receiving the second downlink channel or signal, and the second scrambling code information is used to indicate not receiving the second downlink channel or signal.

[0315] In some embodiments, the receiving the second downlink channel or signal on the second time-frequency resource comprises:

[0316] In a case where the first downlink channel or signal corresponds to the first scrambling code information, the terminal device receives the second downlink channel or signal on the second time-frequency resource; and / or,

[0317] In a case where the first downlink channel or signal corresponds to the second scrambling code information, the terminal device does not receive the second downlink channel or signal on the second time-frequency resource.

[0318] The following is an exemplary description of a scheme in which the second downlink channel or signal is used to carry a paging message. As shown in FIG. 10 or FIG. 11, taking the first downlink channel or signal as an SSB, and the second downlink channel or signal carrying a paging message transmitted on a second time-frequency resource as an example, the terminal device receives the SSB, and the SSB includes first indication information and sixth indication information, wherein the first indication information is used to indicate the time domain position and the frequency domain position of the second time-frequency resource, and the sixth indication information is used to indicate whether the terminal device needs to receive the paging message. The terminal device detects the SSB, and determines the second time-frequency resource according to the first indication information in the SSB after receiving the SSB, and the second time-frequency resource is used to transmit a paging message (Paging). Further, the terminal device determines whether to receive the paging message on the second time-frequency resource according to the sixth indication information in the SSB. When the sixth indication information indicates that the terminal device receives the paging message on the second time-frequency resource, the terminal device receives a first PDSCH carrying the paging message through the second time-frequency resource, as shown in FIG. 10; when the sixth indication information does not indicate that the terminal device receives the paging message on the second time-frequency resource, the terminal device does not receive the paging message on the second time-frequency resource, as shown in FIG. 11.

[0319] In some embodiments, the method further comprises:

[0320] The terminal device, after receiving the paging message, transmits a first uplink channel or signal on a fourth time-frequency resource, the first uplink channel or signal being used for requesting transmission of the system message of the first cell.

[0321] Optionally, the system message of the first cell can include uplink cell access configuration information.

[0322] In some embodiments, the fourth time-frequency resource is determined according to uplink resource configuration information; wherein the uplink resource configuration information is carried in the paging message, or the uplink resource configuration information is carried in the first downlink channel or signal.

[0323] In some embodiments, the fourth time-frequency resource can be preset by a protocol or determined according to the first DCI used for scheduling the paging message.

[0324] In some cases, in order to save energy, the network device does not periodically transmit the system message including the uplink cell access configuration information in the network. However, when the terminal device is called by the network, there is a need to access the network, in which case the terminal device can initiate a request to the network device for transmitting the system message through a preset or network device configured uplink resource.

[0325] The scheme of the terminal device requesting the network device to transmit the system message is exemplarily described below. As shown in FIG. 12, the terminal device receives the first DCI on the PO, receives the first PDSCH according to the scheduling of the first DCI, and judges that the first PDSCH carries the paging message of the terminal device after receiving the first PDSCH. Therefore, the terminal device transmits a first uplink channel or signal on a fourth time-frequency resource, the first uplink channel or signal being used for requesting the network device to transmit the SIB. The network device can transmit the SIB to the terminal device after receiving the first uplink channel or signal. In this example, the fourth time-frequency resource can also be referred to as an on-demand SIB (OD-SIB) resource. The fourth time-frequency resource is determined according to uplink resource configuration information, wherein the uplink resource configuration information can be carried in the first downlink channel or signal, or carried in the first DCI, or carried in the first PDSCH.

[0326] In some embodiments, the terminal device is in one of the following states: idle state, inactive state and connected state.

[0327] The possible implementation manners of the second indication information, the third indication information and the sixth indication information are described below. For ease of description, the possible implementation manners of the second indication information are described by way of example, and the possible implementation manners of the third indication information or the sixth indication information can refer to the possible implementation manners of the second indication information, for example, the second indication information described below is replaced by the third indication information or the sixth indication information, and the function of the second indication information is replaced by the function of the third indication information or the sixth indication information, which will not be described herein again.

[0328] In some embodiments, the second indication information includes one or more bits.

[0329] In some embodiments, a value of the second indication information is used to indicate whether to monitor the second downlink channel or signal.

[0330] In an example, the second indication information includes one bit. When the bit indicates a preset value, for example, 1, it indicates to monitor the second downlink channel or signal; when the bit indicates another preset value, for example, 0, it indicates not to monitor the second downlink channel or does not indicate to monitor the second downlink channel or signal.

[0331] It can be understood that, in order to reduce the power consumption of the terminal device, the network device can divide the terminal devices into multiple groups when paging, and each terminal device belongs to one of the groups. When only terminal devices in part of the groups are paged, terminal devices in other groups can not have to wake up to receive the paging, so as to achieve the purpose of power saving of the terminal.

[0332] In some embodiments, the second indication information can include P bits, P being a positive integer, and each bit of the P bits corresponding to one group.

[0333] In some embodiments, the paging groups can be grouped based on terminal device identifiers.

[0334] For example, the group to which the terminal device belongs is ii = UE_ID mod P.

[0335] Wherein, UE_ID = 6G-S-TMSI mod C, 6G-S-TMSI represents a SIM card identifier of the terminal device, and C is a preset value, for example, C can take a value of 1024 or 2048 or 4096, etc.

[0336] In some embodiments, the paging groups can be allocated by the network device.

[0337] For example, the terminal device directly obtains group information from the network, and the group information is used to indicate the groups.

[0338] In some embodiments, a value of P is preset or indicated by indication information carried in the first downlink channel or signal.

[0339] In some embodiments, the second indication information can include P*Q bits, P and Q are positive integers, each bit in the P bits corresponds to a group, and each bit in the Q bits corresponding to each group corresponds to a subgroup in each group. That is, the concept of subgrouping is further introduced on the basis of P groups. When only part of the subgroups of UEs are paged, the UEs in other subgroups can not have to wake up to receive the paging, so as to achieve the purpose of terminal power saving.

[0340] In some embodiments, the paging subgroups can be grouped based on terminal device identifiers.

[0341] Exemplarily, the terminal device belongs to a subgroup jj=(UE_ID mod P) mod Q.

[0342] Wherein, UE_ID=6G-S-TMSI mod C, 6G-S-TMSI represents the SIM card identifier of the terminal device, and C is a preset value, for example, C can take values such as 1024 or 2048 or 4096.

[0343] In some embodiments, the paging subgroups can be allocated by the network device. For example, the terminal device directly obtains subgroup grouping information from the network, and the subgroup grouping information is used to indicate the subgroups.

[0344] In some embodiments, the value of P is preset or indicated by the indication information carried in the first downlink channel or signal; and / or, the value of Q is preset or indicated by the indication information carried in the first downlink channel or signal.

[0345] It can be understood that in the case of grouping, the terminal device only needs to determine whether to monitor the PO based on the indication of the bit corresponding to the group or subgroup to which the terminal device belongs in the second indication information, so as to achieve the purpose of terminal power saving.
