[0044] 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. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0045] FIG. 1 is a schematic diagram of a communication architecture.

[0046] As shown in FIG. 1, the communication system 100 can include a terminal device 110 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.

[0047] It should be understood that the embodiments of the present application are only exemplarily described with respect to the communication system 100, but the embodiments of the present application are not limited thereto.

[0048] 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 located in the coverage area.

[0050] The terminal device 110 can be any terminal device, including but not limited to a terminal device that uses a wired or wireless connection with the network device 120 or other terminal devices.

[0053] It should be understood that the communication system 100 can include multiple network devices and each network device can include other number of terminal devices within its coverage, and the embodiments of the present application do not limit this.

[0054] It should be noted that FIG. 1 only schematically shows a system to which the present application is applicable, and of course, the method shown in the embodiments of the present application can also be applicable to other systems. In addition, the terms "system" and "network" are often used interchangeably in the present application.

[0055] It should be understood that the term "and / or" in the present application is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the associated objects.

[0056] It should also be understood that the "indication" mentioned in the embodiments of the present application can be direct indication, indirect indication, or can also mean having an association relationship. For example, A indicates B, which can mean that B can be obtained by A directly; or it can mean that A indirectly indicates B, for example, A indicates C, and B can be obtained by C; or it can mean that A and B have an association relationship.

[0058] It should also be understood that the "predefined" or "predefined rule" mentioned in the embodiments of the present application can be realized by pre-saving corresponding codes, tables or other means that can be used to indicate related information in devices (for example, including terminal devices and network devices), and the specific implementation manner of the present application is not limited. For example, the predefined can refer to the definition in the protocol. It should also be understood that the "protocol" in the embodiments of the present application can refer to a standard protocol in the communication field, for example, can include the LTE protocol, the NR protocol and the related protocol applied in the future communication system, and the present application is not limited to this.

[0059] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows, and the following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, which all belong to the protection scope of the embodiments of the present application.

[0060] With the pursuit of rate, delay, high-speed mobility, energy efficiency, and the demand for diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization began to develop the 5th Generation Mobile Communication Technology (5G).

[0061] At present, the main application scenarios of 5G include: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (URLLC), and Massive Machine Type Communications (mMTC).

[0062] Among them, eMBB aims to obtain multimedia content, services and data for users, and its demand is growing rapidly. On the other hand, since eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., the difference between its capabilities and requirements is also large, so it cannot be generalized and must be analyzed in detail in combination with the specific deployment scenario. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (such as surgery), traffic safety protection, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules, and long service life, etc.

[0063] In order to reduce air interface signaling and quickly recover wireless connection and data service in 5G network environment, a new RRC state, RRC inactive state (RRC_INACTIVE) is defined. This state is different from RRC idle state (RRC_IDLE) and RRC connected state (RRC_CONNECTED). The following describes the three states in detail.

[0064] In RRC_IDLE, mobility is based on UE cell selection / reselection, paging is initiated by the CN, and the paging area is configured by the CN. There is no UE AS context on the base station side, and there is no RRC connection between the base station and the UE.

[0065] In RRC_CONNECTED, there is an RRC connection, and there is a UE AS context between the base station and the UE. The network side knows the location of the UE is specific to the cell level. Mobility is network-controlled mobility. UE and base station can transmit unicast data.

[0066] In RRC_INACTIVE, mobility is based on UE cell selection / reselection, there is a connection between CN and NR, UE AS context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and the network side knows the location of the UE is based on the RAN-based paging area level.

[0067] The following describes the energy saving technology of 5G network.

[0068] At present, energy consumption has become an important part of the operator's operating costs. According to reports, the energy cost of mobile networks accounts for about 23% of the total cost of operators. Most of the energy consumption comes from the radio access network, especially the active antenna unit (AAU), while the data center and fiber transmission only account for a small share.

[0069] The power consumption of a mobile network includes two parts:

[0070] Dynamic part: such as the consumption when data transmission / reception is performed;

[0071] Static part: such as the consumption for keeping the necessary operation of the radio access equipment even if there is no continuous data transmission / reception at this time.

[0072] The network energy saving technology should not only evaluate the potential network energy consumption benefits, but also evaluate and balance the impact on network and user performance. For example, the energy saving technology should not have a particularly large impact on some KPIs, such as: spectral efficiency, capacity, user perceived throughput (UPT), delay, UE power consumption, complexity, handover performance, call drop rate, initial access performance, etc.

[0073] In the related art, if a secondary cell (SCell) and a special cell (sPcell) or other SCell are co-located cells, the SCell can not transmit SSB, and here the SCell not transmitting SSB is referred to as an SSB-less SCell. As the SSB-less SCell, the UE synchronizes with another cell, and can communicate on the SSB-less cell.

[0074] At present, the network energy saving technology has extended the intra-band scenario to the inter-band scenario, that is, the SSB-less cell can obtain SSB through other inter-band cells.

[0075] It can be understood that a cell can not transmit SSB, but needs to meet the following conditions:

[0076] 1) The cell is an SCell, that is, it is limited to the UE in the RRC_CONNECTED state, and is not applicable to the sPcell;

[0077] 2) The cell and the sPcell or other SCell are co-located cells.

[0078] In this case, the UE can obtain SSB from Cell-A for communication on the SSB-less Cell-B, that is, the above-mentioned "the UE synchronizes with another cell, and can communicate on the SSB-less cell". In this scheme, the SSB-less SCell does not need to transmit SSB at all.

[0079] How to further reduce the power consumption of the network side for the UE in the RRC_IDLE state and the RRC_INACTIVE state, and how to distribute SSBs, paging messages, and random access channels (RACHs) in the case of multiple bandwidths in one cell coverage are technical problems to be solved by the present application.

[0080] 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, and 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.

[0081] FIG. 2 is a flowchart of an information transmission method provided by an embodiment of the present application. As shown in FIG. 2, the method can include the following steps.

[0082] S210, the terminal device sends first information, and correspondingly, the network device can receive the first information.

[0083] The first information is used to trigger the network device to send SSBs and / or system messages.

[0084] It should be noted that the first information can be referred to as an uplink signal (UL-signal), a wake-up signal (Wake Up Signal), or a trigger signal, and the embodiments of the present application do not limit this.

[0085] It should be further noted that the system message can be various types of system information blocks (SIBs), for example, the system information can be SIBx, where x is any positive integer.

[0086] It can be understood that in the embodiments of the present application, the network device can not send SSBs and / or system messages, but listen to the first information sent by the terminal device, and the network device sends SSBs and / or system messages based on the received first information. In actual application, the power consumption of receiving information is less than that of sending information. In this way, the network device can avoid always-on sending SSBs and / or system messages, and send SSBs and / or system messages based on the first information sent by the terminal device, thereby saving power.

[0087] In an embodiment of the present application, the terminal device can send the first information based on first configuration information in S210. Correspondingly, the network device can receive the first information based on the first configuration information. The configuration information is used to configure the transmission parameters of the first information.

[0088] In some embodiments, the first configuration information can comprise one or more of the following:

[0089] a first time domain resource for transmitting the first information;

[0090] a first frequency domain resource for transmitting the first information;

[0091] power information for transmitting the first information;

[0092] a first time length; the first time length is used to determine whether to retransmit the first information;

[0093] a starting time of a time window;

[0094] a time length of the time window;

[0095] an ending time of the time window; the time window is used to determine whether to retransmit the first information;

[0096] a maximum number of transmissions of the first information;

[0097] a first mapping relationship, the first mapping relationship representing a mapping relationship between a first time domain resource for transmitting the first information and a time domain resource for monitoring an SSB and / or a system message;

[0098] a second mapping relationship, the second mapping relationship representing a mapping relationship between a first frequency domain resource for transmitting the first information and a frequency domain resource for monitoring the SSB and / or the system message.

[0099] In some embodiments, the first configuration information can configure the first time domain resource through a specific time, or can configure the first time domain resource through an index value of a time slot or an OFDM symbol. The embodiments of the present application do not limit the configuration mode of the first time domain resource.

[0100] It should be understood that, before transmitting the first information, the terminal device needs to be time-synchronized with the network device, so as to ensure the correct transmission of the first information. That is, the terminal device needs to determine the first time domain resource for transmitting the first information based on a reference time.

[0101] In some embodiments, the terminal device can be time-synchronized based on one or more of the following, or the reference time of the first time domain resource can be determined based on one or more of the following:

[0102] timing information transmitted by a Global Navigation Satellite System (GNSS);

[0103] a reception time of a reference signal associated with another Radio Access Technology (RAT).

[0104] a reception time of a reference signal associated with the current RAT.

[0105] It should be noted that the reference signal associated with the RAT can be an SSB, a system message, a reference signal (RS), etc. transmitted on a frequency point supported by the RAT, and the embodiments of the present application do not limit this.

[0106] In an example, if the first time domain resource is time information, the terminal device can perform time synchronization with the network according to the timing information of the GNSS, so as to determine to send the first information at the time indicated by the first time domain resource.

[0107] In another example, if the terminal device needs to acquire the SSB of Cell-A operating on the frequency point A, the terminal device can take the reception time of the SSB sent by Cell-B operating on the frequency point B as a time reference to determine the first time domain resource for sending the first information to Cell-A. Wherein, Cell-A and Cell-B can support the same RAT, or can support different RATs.

[0108] In addition, the first configuration information can configure the first frequency domain resource through the frequency point and the bandwidth, or can configure the first frequency domain resource through the index value. Specifically, the index value can indicate any one of the pre-defined / pre-configured resource pool.

[0109] It should be noted that the first time domain resource and / or the first frequency domain resource can include one or more.

[0110] In some embodiments, in the case where the number of the first time domain resource and / or the first frequency domain resource includes multiple, the terminal device can send the first information on multiple first time domain resources and / or multiple first frequency domain resources.

[0111] In some embodiments, in the case where the number of the first time domain resource and / or the first frequency domain resource includes multiple, the terminal device can select one first time domain resource from the multiple first time domain resources and / or select one first frequency domain resource from the multiple first frequency domain resources to transmit the first information based on a preset rule.

[0112] For example, taking the frequency domain resource as an example, the terminal device can select the first frequency domain resource with the highest priority from the multiple first frequency domain resources to transmit the first information, the terminal device can select the frequency domain resource corresponding to the frequency point requiring to initiate service transmission from the multiple first frequency domain resources to transmit the first information, and the terminal device can select the first frequency domain resource with the optimal channel condition from the multiple first frequency domain resources to transmit the first information.

[0113] It should be noted that the first time domain resource and / or the first frequency domain resource are related to the geographical position of the terminal device.

[0114] It should be understood that, considering the difference in network deployment, base stations in different geographical positions can be deployed on different frequency points, that is, the frequency points at which base stations in different geographical positions operate are different, and therefore the terminal device needs to send the first information with different first time domain resources and / or first frequency domain resources in different geographical positions. The first configuration information needs to distinguish the first time domain resource and / or the first frequency domain resource according to the geographical position.

[0115] The geographical position can be determined based on one or more of the following:

[0116] The latitude and longitude coordinates

[0117] The cell accessed / resided in;

[0118] The tracking area (TA);

[0119] The public land mobile network (PLMN) identifier;

[0120] The mobile network code (MNC);

[0121] The mobile country code (MCC).

[0122] In some embodiments, the first configuration information can distinguish the first time domain resource and / or the first frequency domain resource for sending the first information according to one or more of the above latitude and longitude coordinates, the cell accessed / resided in by the terminal device, the TA, the PLMN identifier, the MNC, and the MCC. That is, the first configuration information can configure the corresponding first time domain resource and / or first frequency domain resource in different geographical positions. In this way, the terminal device can determine the specific first time domain resource and / or first frequency domain resource according to the geographical position it is in.

[0123] In actual application, there are abnormal situations in which the first information triggers the network device to send the SSB and / or system message unsuccessfully. In order to prevent the network device from not successfully receiving the first information, the terminal device is configured with a corresponding abnormal handling mechanism.

[0124] In an example, the terminal device can listen to the SSB and / or system message sent by the network device within a first time length after sending the first information. If the terminal device does not receive the SSB and / or system message sent by the network device within the first time length, the terminal device re-sends the first information.

[0125] In another example, after sending the first information, the terminal device can listen to the SSB and / or system message sent by the network device within a time window. If the terminal device does not receive the SSB and / or system message sent by the network device within the time window, the terminal device re-sends the first information. The time window can be determined according to one or more of the starting time, the duration, and the ending time.

[0126] It should be noted that the starting time of the time window can be the same as the time when the terminal device sends the first information, or can be spaced apart from the time when the terminal device sends the first information by a certain duration, which is not limited herein.

[0127] Further, after the terminal device re-sends the first information, it can continue to listen to the SSB and / or system message based on the first duration or the time window. If the terminal device receives the SSB and / or system message, it stops sending the first information. If the terminal device still does not receive the SSB and / or system message within the first duration or the above-mentioned time window, it re-sends the first information again until the number of transmissions of the first information reaches the maximum number of transmissions of the first information. Alternatively, the terminal device can increase the transmission power when re-sending the first information.

[0128] It can be understood that the parameters used by the terminal device to handle abnormal situations include one or more of the first duration, the starting time of the time window, the duration of the time window, the ending time of the time window, the maximum number of transmissions of the first information, and the power information, which can be configured by the first configuration information.

[0129] In some embodiments, the first configuration information can further configure a mapping relationship (i.e., a first mapping relationship) between the first time domain resource and the time domain resource for listening to the SSB and / or system message, and / or a mapping relationship (i.e., a second mapping relationship) between the first frequency domain resource and the frequency domain resource for listening to the SSB and / or system message.

[0130] It should be noted that the relationship between the time and frequency domain resources for sending the first information (hereinafter referred to as time and frequency resources) and the time and frequency resources for receiving the SSB and / or system message can be jointly configured. That is, the first configuration information can configure the mapping relationship between the time and frequency resources for sending the first information and the time and frequency resources for receiving the SSB and / or system message.

[0131] It should also be noted that the number of time domain resources for listening to the SSB and / or system message associated with the first time domain resource includes one or more. Correspondingly, the number of frequency domain resources for listening to the SSB and / or system message associated with the first frequency domain resource can also include one or more.

[0132] It can be understood that the first configuration information can configure the first mapping relationship and / or the second mapping relationship, so that the terminal device detects the SSB and / or the system message sent by the network device at the associated time domain position and / or frequency domain position after sending the first information.

[0133] In some embodiments, the first configuration information can be configured by any of the following:

[0134] a core network element;

[0135] a server;

[0136] an access network element;

[0137] information predefined by a protocol;

[0138] information stored in a terminal device storage space;

[0139] information stored in a Subscriber Identity Module (SIM) card.

[0140] It can be understood that the first configuration information can be configured in advance at the terminal side. Through the pre-configuration manner, the terminal device can know the transmission parameter of the first information in advance. In this way, the terminal device can send the first information to the network device based on the transmission parameter configured by the first configuration information, so as to trigger the network device to send the SSB and / or the system message without searching for the network.

[0141] In an embodiment of the present application, the first information can be sent under the condition that a first condition is met. The first condition includes one or more of the following:

[0142] the terminal device is configured with one or more frequency point information;

[0143] the terminal device does not search for a network signal on a frequency point corresponding to any frequency point information of the one or more frequency point information.

[0144] It should be noted that the one or more frequency point information mentioned above can refer to the frequency point information of the network sending the SSB and / or the system message. The network signal can be the SSB and / or the system message, and the network signal can also be other signals, which are not limited by the embodiments of the present application.

[0145] It should be understood that if the terminal device does not know / configure the frequency point information of the network sending the SSB and / or the system message, it cannot send the first information. For the network device that is already in the state of sending the SSB and / or the system message, the terminal device does not need to send the first information to trigger the network device to send the SSB and / or the system message.

[0146] Therefore, the terminal device sends the first information to trigger the network device to send the SSB and / or the system message only when the terminal device is configured with the one or more frequency point information and no network signal is searched on the configured one or more frequency point information.

[0147] In some embodiments, the one or more frequency point information is determined by one or more of the following:

[0148] The first frequency domain resource for transmitting the first information;

[0149] The second configuration information.

[0150] In some embodiments, the one or more frequency point information can be determined by the first time domain resource configured in the first configuration information.

[0151] It should be understood that the one or more frequency point information described above can refer to the frequency point information at which the network device sends the SSB and / or the system message.

[0152] In an example, for a time division duplexing (TDD), the same frequency point is used for uplink and downlink. That is, the frequency point at which the network device sends the SSB and / or the system message and the first frequency domain resource at which the network device listens to the first information are overlapped. Therefore, for a TDD system, the terminal device can take the first frequency domain resource configured by the first configuration information as the frequency point information at which the network device sends the SSB and / or the system message.

[0153] In another example, for a network device supporting frequency division duplexing (FDD), different frequency points are used for uplink and downlink. The frequency points of uplink and downlink are separated by a fixed frequency domain interval. Therefore, in an FDD system, the terminal device can determine the frequency point information at which the network device sends the SSB and / or the system message based on the first frequency domain resource configured by the first configuration information and the fixed frequency domain interval.

[0154] In some embodiments, the one or more frequency point information can be directly configured by the second configuration information. It should be noted that the second configuration information can be the same configuration information as the first configuration information, and the second configuration information and the first configuration information can also be different configuration information, which is not limited in the embodiments of the present application.

[0155] In some embodiments, the second configuration information can be configured by any of the following:

[0156] A core network element;

[0157] A server;

[0158] An access network element;

[0159] information predefined by the protocol;

[0160] information stored in a storage space of the terminal device;

[0161] information stored in the SIM card.

[0162] In some embodiments, the number of the one or more frequency point information includes a plurality, and before the terminal device sends the first information in S210, the method further includes the following steps:

[0163] The terminal device determines the first frequency point information; and the first frequency domain resource at which the terminal device sends the first information is related to the first frequency point information in the one or more frequency point information.

[0164] It can be understood that, in the case that the terminal device is configured with a plurality of frequency point information, the terminal device can select one frequency point information (hereinafter referred to as the first frequency point information) from the plurality of frequency point information, and take the frequency point corresponding to the first frequency point information as the frequency point to be accessed by the terminal device. That is, or, the terminal device can trigger the network to send SSB and / or system message on the frequency point corresponding to the first frequency point information through the first information, so as to facilitate the terminal device to access the network based on the SSB and / or system message.

[0165] Generally, the first frequency domain resource at which the terminal device sends the first information can be related to the first frequency point information to be accessed. Exemplarily, for a TDD system, the uplink and the downlink use the same frequency point, therefore, the first frequency point information determined by the terminal device overlaps with the first frequency domain resource. For a Frequency Division Duplexing (FDD) system, the uplink and the downlink use different frequency points, therefore, the first frequency point information determined by the terminal device can be spaced apart from the first frequency domain resource by a certain frequency interval.

[0166] In some embodiments, the first frequency point information is determined based on one or more of the following:

[0167] The first frequency point information is the frequency point information with the highest priority in the one or more frequency point information;

[0168] The channel quality detected by the terminal device on the frequency point associated with the first frequency point information satisfies a first threshold value;

[0169] The first frequency point information is the frequency point information on which the terminal device is to initiate service transmission.

[0170] It can be understood that, the terminal device can select the first frequency point information from the plurality of frequency point information according to certain criteria.

[0171] In some embodiments, the terminal device can select the frequency point information with the highest priority from the multiple frequency point information as the first frequency point information. The priority of the frequency point information can be determined according to the RAT supported by the terminal device, or determined according to the frequency point information historically accessed by the terminal device, which is not limited in the embodiments of the present application.

[0172] In some embodiments, the terminal device can detect the channel quality on the frequency points associated with the multiple frequency point information, and select the frequency point information associated with the frequency point whose channel quality satisfies the first threshold value as the first frequency point information.

[0173] It should be noted that the frequency point associated with the frequency point information can be the frequency point adjacent to the frequency point information, or the frequency point spaced apart from the frequency point information by a certain frequency, which is not limited in the embodiments of the present application. The first threshold value can be pre-defined by the protocol, or configured by the network device, which is not limited in the embodiments of the present application.

[0174] For example, the terminal device is configured with frequency point A and frequency point B. The terminal device can detect the channel quality of frequency point A' adjacent to frequency point A, and detect the channel quality of frequency point B' adjacent to frequency point B. If the channel quality of frequency point B' is greater than the first threshold value, frequency point B is selected as the frequency point to be accessed by the terminal device.

[0175] In some embodiments, the terminal device can select the frequency point information from which the service transmission is about to be initiated from the multiple frequency point information as the first frequency point information.

[0176] In an embodiment of the present application, with reference to the information transmission method shown in FIG. 3, after the terminal device transmits the first information, and the network device receives the first information, the following steps can be further included:

[0177] S220, the network device transmits the SSB and / or the system message on the second time domain resource and / or the second frequency domain resource, and correspondingly, the terminal device listens to the SSB and / or the system message transmitted by the network device on the second frequency domain resource and / or the second time domain resource.

[0178] The second time domain resource can be determined based on one or more of the following:

[0179] The third configuration information;

[0180] The first time domain resource on which the terminal device transmits the first information;

[0181] The first time domain resource and the time offset parameter;

[0182] The first time domain resource and the first mapping relationship, the first mapping relationship representing the mapping relationship between the first time domain resource on which the first information is transmitted and the time domain resource on which the SSB and / or the system message is listened to.

[0183] In some embodiments, the network device transmits the SSB and / or the system message, and the second time domain resource in which the terminal device monitors the SSB and / or the system message can be directly configured by the third configuration information. Exemplarily, the third configuration information can configure the second time domain resource by a specific time, or can configure the second time domain resource by an index value of a time slot or an OFDM symbol, and the embodiments of the present application do not make any limitation in this regard.

[0184] It should be noted that the third configuration information can be the same information as the first configuration information, or can be different information, and the embodiments of the present application do not make any limitation in this regard.

[0185] It should be further noted that the third configuration information can be configured by any one of the following:

[0186] a core network element;

[0187] a server;

[0188] an access network element;

[0189] information predefined by a protocol;

[0190] information stored in a storage space of the terminal device;

[0191] information stored in a SIM card.

[0192] In some embodiments, the network device transmits the SSB and / or the system message, and the second time domain resource in which the terminal device monitors the SSB and / or the system message can be determined by the first time domain resource.

[0193] It can be understood that the first time domain resource can be the same as the second time domain resource. That is, the terminal device can simultaneously transmit the first information and monitor the SSB and / or the system message triggered by the first information.

[0194] In some embodiments, the network device transmits the SSB and / or the system message, and the second time domain resource in which the terminal device monitors the SSB and / or the system message can be determined by the first time domain resource and a time offset parameter.

[0195] It can be understood that the first time domain resource in which the terminal device transmits the first information can be staggered in time with the second time domain resource in which the terminal device monitors the SSB and / or the system message. The first time domain resource in which the terminal device transmits the first information can be separated from the second time domain resource in which the terminal device monitors the SSB and / or the system message by a period of time. The period of time is determined by the time offset parameter.

[0196] It should be noted that the time offset parameter can be predefined, or can be configured by the first configuration information, or can be configured by a separate configuration information, and the embodiments of the present application do not make any limitation in this regard.

[0197] In some embodiments, the network device transmits the SSB and / or the system message, and the second time domain resource in which the terminal device monitors the SSB and / or the system message can be determined based on the first time domain resource and a first mapping relationship. The first mapping relationship represents a mapping relationship between the first time domain resource in which the first information is transmitted and the time domain resource in which the SSB and / or the system message is monitored. It can be understood that after the terminal device and the network device determine the first time domain resource in which the first information is transmitted, the second time domain resource associated with the first time domain resource can be determined according to the first mapping relationship.

[0198] In the embodiments of the present application, the second frequency domain resource can be determined based on one or more of the following:

[0199] The fourth configuration information;

[0200] The first frequency domain resource in which the terminal device transmits the first information;

[0201] The first frequency domain resource and the frequency domain offset parameter;

[0202] The first frequency domain resource and a second mapping relationship. The second mapping relationship represents a mapping relationship between the first frequency domain resource in which the first information is transmitted and the frequency domain resource in which the SSB and / or the system message is monitored.

[0203] In some embodiments, the network device transmits the SSB and / or the system message, and the second frequency domain resource in which the terminal device monitors the SSB and / or the system message can be directly configured by the fourth configuration information. For example, the fourth configuration information can configure the second frequency domain resource through a frequency point and a bandwidth, or can configure the second frequency domain resource through an index value, and the embodiments of the present application do not limit this.

[0204] It should be noted that the fourth configuration information and the first configuration information can be the same information or different information, and the embodiments of the present application do not limit this.

[0205] It should also be noted that the fourth configuration information can be configured by any of the following:

[0206] The core network element;

[0207] The server;

[0208] The access network element;

[0209] The protocol predefined information;

[0210] The information stored in the storage space of the terminal device;

[0211] The information stored in the SIM card.

[0212] In some embodiments, the second frequency domain resource, on which the network device transmits the SSB and / or the system message, and on which the terminal device monitors the SSB and / or the system message, can be determined by the first frequency domain resource. For example, the second frequency domain resource is the same as the first frequency domain resource, that is, the network device monitors the first information and transmits the SSB and / or the system message on the same frequency domain resource, and the terminal device transmits the first information and monitors the SSB and / or the system message on the same frequency domain resource.

[0213] In some embodiments, the second frequency domain resource, on which the network device transmits the SSB and / or the system message, and on which the terminal device monitors the SSB and / or the system message, can be determined by the first frequency domain resource and a frequency domain offset parameter. That is, the frequency domain resource, on which the network device monitors the first information, is separated from the frequency domain resource, on which the network device transmits the SSB and / or the system message, by the frequency domain offset parameter, and the frequency domain resource, on which the terminal device transmits the first information, is separated from the frequency domain resource, on which the terminal device monitors the SSB and / or the system message, by the frequency domain offset parameter.

[0214] It should be noted that the frequency domain offset parameter can be predefined, configured by the first configuration information, or configured by a separate configuration information, and the embodiments of the present application do not limit this.

[0215] In some embodiments, the second frequency domain resource, on which the network device transmits the SSB and / or the system message, and on which the terminal device monitors the SSB and / or the system message, can be determined by the first frequency domain resource and a second mapping relationship. The second mapping relationship represents the mapping relationship between the first frequency domain resource and the frequency domain resource on which the SSB and / or the system message is monitored. It can be understood that after the terminal device and the network device determine the first frequency domain resource on which the first information is transmitted, the second frequency domain resource associated with the first frequency domain resource can be determined according to the second mapping relationship.

[0216] In an embodiment of the present application, with reference to the information transmission method shown in FIG. 4, after S220, the following steps can be further included:

[0217] S230, the network device transmits the second information to other network devices, and the second information is used to trigger the other network devices to transmit the SSB and / or the system message.

[0218] It should be understood that the terminal device can trigger the network device A to send the SSB and / or the system message through the first information. However, if only the network device A is triggered to send the SSB and / or the system message, it can cause that the terminal device cannot trigger the network device B to send the SSB and / or the system message, or the uncertainty of triggering the network device B to send the SSB and / or the system message. Moreover, only triggering the network device A to send the SSB and / or the system message is not conducive to reducing the access delay of the terminal device. It should be noted that the tracking areas (TA) of the network device A and the network device B are different, or the network device A and the network device B are two network devices that satisfy a certain distance range.

[0219] Based on this, in the embodiments of the present application, when the network device receives the first information sent by the terminal device, the second information can be sent to other network devices to trigger other network devices to send the SSB and / or the system message.

[0220] In some embodiments, the other network devices include one or more of the following:

[0221] The network devices in other tracking areas adjacent to the tracking area of the current network device;

[0222] The network devices with a distance greater than or equal to the first distance from the current network device.

[0223] In some embodiments, after receiving the first information, the network device can notify the network devices in the adjacent TA to send the SSB and / or the system message. In this way, when the terminal device enters the adjacent TA, for example, performs a tracking area update (TAU), it can receive the SSB and / or the system message sent by the network devices in the adjacent TA, so as to quickly perform cell switching and reduce the access delay of the terminal device.

[0224] In some embodiments, after receiving the first information, the network device can notify the outer ring network devices with a distance greater than the first distance from the current network device to send the SSB and / or the system message. In this way, when the terminal device moves into the coverage range of the outer ring network device, it can quickly perform access, thereby reducing the access delay of the terminal device.

[0225] It should be noted that after the other network devices receive the second information, they can also send the second information to trigger the network devices in the outer ring to send the SSB and / or the system message.

[0226] It can be understood that the network devices in the network can not continuously send the SSB and / or the system message, but listen to the first information sent by the terminal device, or receive the second information sent by other network devices to perform the sending of the SSB and / or the system message, thereby saving the network power consumption.

[0227] In an embodiment of the present application, based on the information transmission method shown in FIG. 2, referring to FIG. 5, the present embodiment can further include the following steps after S210:

[0228] S240, if the terminal device does not receive the SSB and / or system message within the first time duration after sending the first information, or the terminal device does not receive the SSB and / or system message within the time window, the terminal device re-sends the first information.

[0229] In some embodiments, in order to avoid the abnormal situation that the network device does not successfully receive the first information, the terminal device can listen to the SSB and / or system message sent by the network device within the first time duration after sending the first information. If the terminal device does not receive the SSB and / or system message sent by the network device within the first time duration after sending the first information, the terminal device re-sends the first information.

[0230] Exemplarily, the first time duration can be implemented by a timer. For example, the terminal device can start the timer after sending the first information, and the stop condition of the timer is that the terminal device receives the SSB and / or system message. If the terminal device has not received the SSB and / or system message when the timer expires, the terminal device re-sends the first information.

[0231] In some embodiments, in order to avoid the abnormal situation that the network device does not successfully receive the first information, the terminal device can listen to the SSB and / or system message within a time window after sending the first information. If the terminal device does not receive the SSB and / or system message within the time window, the terminal device re-sends the first information.

[0232] It should be noted that the time window can be determined according to one or more of the start time, the duration, and the end time.

[0233] Exemplarily, the above-mentioned time window can be implemented in combination with a timer. For example, the terminal device can start the timer at the start time of the time window after sending the first information, wherein the duration of the timer is the duration of the time window. The stop condition of the timer is that the terminal device receives the SSB and / or system message. If the terminal device has not received the SSB and / or system message when the timer expires, the terminal device re-sends the first information.

[0234] It should be noted that the start time of the time window can be the same as the time when the terminal device sends the first information, or can be spaced apart from the time when the terminal device sends the first information by a certain duration, which is not limited in the present embodiment.

[0235] It should be noted that the first time length, the start time of the time window, the duration of the time window, and the end time of the time window can be configured by the first configuration information. The configuration manner is described in the above embodiments, and details are not described here for brevity.

[0236] In some embodiments, before the terminal device retransmits the first information in S240, the terminal device can also reset the transmission power. For example, the terminal device can increase the transmission power of the first information by a preset step each time the first information is retransmitted, until the transmission power of the first information reaches the maximum transmission power supported by the terminal device.

[0237] In some embodiments, when the number of times the terminal device transmits the first information is equal to the maximum number of transmissions, the terminal device stops transmitting the first information on the first frequency domain resource. Further, the terminal device selects a third frequency domain resource to transmit the first information, wherein the third frequency domain resource is different from the first frequency domain resource.

[0238] It can be understood that when the number of times the terminal device transmits the first information reaches the maximum number of transmissions, the terminal device no longer continues to attempt to transmit the first information on the first frequency domain resource. The terminal device can reselect other frequency points for access. Specifically, the terminal device can select a third frequency domain resource different from the first frequency domain resource to transmit the first information.

[0239] It should be noted that the terminal device in the embodiments of the present application can be in RRC_IDLE or RRC_INACTIVE. It should be understood that the terminal device can transmit the first information based on the first configuration information when no network is searched, to trigger the network device to transmit the SSB and / or system message. The network device can listen to the first information transmitted by the terminal device, and transmit the SSB and / or system message based on the received first information. In actual application, the power consumed by receiving information is less than that of transmitting information. In this way, the network device can avoid transmitting the SSB and / or system message always, and transmit the SSB and / or system message based on the first information transmitted by the terminal device, thereby saving power.

[0240] FIG. 6 is a flowchart of another information transmission method provided by the embodiments of the present application. As shown in FIG. 6, the method can include the following steps:

[0241] S610, the network device transmits the SSB and / or system message, and correspondingly, the terminal device receives the SSB and / or system message. The SSB and / or system message includes fifth configuration information, and the fifth configuration information includes at least one frequency point information associated with the SSB and / or system message.

[0242] It can be understood that the SSB and / or system message can configure at least one frequency point information associated with the current SSB and / or system message.

[0243] It should be noted that the at least one frequency point information can be configured by absolute frequency information, or can be configured by frequency index value / frequency indication of a certain numerology. The embodiments of the present application do not limit this.

[0244] It should be further noted that the frequency point information herein can be replaced by bandwidth information (Bandwidth).

[0245] In some embodiments, the network device sends the SSB and / or system message, which can be based on the method in the above embodiments, based on the first information sent by the terminal device. In other embodiments, the network device sends the SSB and / or system message, which can be always-on sending. The embodiments of the present application do not limit the sending method of the SSB and / or system message.

[0246] It can be understood that in the embodiments of the present application, the use range of the SSB and / or system message can be extended from a single frequency point to multiple frequency points, thereby facilitating subsequent operations of the terminal device.

[0247] In an embodiment of the present application, after S610, the following steps can also be included:

[0248] The terminal device determines second frequency point information; the second frequency point information is any one of the at least one frequency point information associated with the SSB and / or system message;

[0249] The terminal device performs uplink transmission and / or downlink reception based on the second frequency point information.

[0250] The uplink transmission includes one or more of the following:

[0251] The first information is sent, and the first information is used to trigger the network device to send the SSB and / or system message;

[0252] The random access channel (RACH) is sent.

[0253] In addition, the downlink reception includes receiving a paging message.

[0254] It can be understood that the terminal device can select one frequency point on the at least one frequency point associated with the SSB and / or system message for paging reception, and / or first information / RACH transmission.

[0255] That is, the terminal device can perform downlink reception and / or uplink transmission operations on different frequency points, thereby distributing different services to different frequency points to balance the load.

[0256] In some embodiments, the terminal device can select the second frequency point information from the at least one frequency point information associated with the SSB and / or system message based on one or more of the following parameters:

[0257] The maximum number of bands;

[0258] The maximum number of frequency points;

[0259] The maximum number of carriers;

[0260] The maximum number of frequency domain resources;

[0261] Service type information;

[0262] Identity information of the terminal device;

[0263] Device group information of the terminal device;

[0264] Capability information of the terminal device;

[0265] Channel quality information.

[0266] It should be noted that the service type can include 3GPP service, non-3GPP (non-3GPP) service, voice service, network slice service, etc., and the embodiments of the present application do not limit this.

[0267] It should also be noted that the identity information of the terminal device can be identity information of the terminal device (i.e. UE ID), or various types of UE temporary identifiers, and the embodiments of the present application do not limit this.

[0268] In addition, the capability information of the terminal device can refer to whether the terminal device supports the capability of associating multiple frequency point information with one SSB and / or system message.

[0269] In an example, the terminal device can perform a modulo operation on the UE ID with respect to the maximum number of frequency domain resources (or the maximum number of bands, the maximum number of frequency points, the maximum number of carriers) to select different second frequency point information for paging listening and / or transmission of the first information / RACH.

[0270] In an example, different service types correspond / associate different frequency point information. The terminal device can select the corresponding frequency point information as the second frequency point information according to the service type information of the currently executed service.

[0271] In an example, different frequency point information can be associated with different channel quality thresholds. The terminal device can obtain channel quality information based on SSB and / or system information measurement, and then associate the frequency point information associated with the currently measured channel quality information as the second frequency point information based on the association relationship between the channel quality threshold and the frequency point information.

[0272] In an example, different frequency point information can correspond to different terminal device identity information / device group information. The terminal device can associate the frequency point information corresponding to the current terminal device identity information / device group information as the second frequency point information based on the correspondence.

[0273] It should be noted that the maximum number of bands, the maximum number of frequency points, the maximum number of carriers, the maximum number of frequency domain resources, the service type information corresponding to each frequency point information in the at least one frequency point information, the channel quality threshold associated with each frequency point information in the at least one frequency point information, the terminal device identity information corresponding to each frequency point information in the at least one frequency point information, and the device group information corresponding to each frequency point information in the at least one frequency point information mentioned above can be configured by the fifth configuration information.

[0274] The information transmission method provided by the embodiments of the present application will be described in detail below in combination with specific application scenarios.

[0275] Embodiment One

[0276] Referring to FIG. 7, a flowchart of an information transmission method provided by an embodiment of the present application is shown, including the following steps:

[0277] S1, the UE obtains first configuration information.

[0278] In some embodiments, the first configuration information can configure the time-frequency resources for the UE to send the UL-signal (i.e., the first information mentioned above).

[0279] It should be noted that the time reference of the time-frequency resources can come from the timing information sent by GNSS, or the reception time of the reference signal associated with the current RAT, or the reception time of the reference signal associated with other RATs, which is not limited by the embodiments of the present application.

[0280] Optionally, the first configuration information can distinguish the time-frequency resources for sending the UL-signal according to different geographical locations.

[0281] It should be noted that the geographical location can be determined based on one or more of the following:

[0282] Latitude and longitude coordinates, accessed / resided cells, TA, PLMN identifier, MNC, MCC.

[0283] It should be understood that, considering the difference of network deployment, base stations in different geographical locations can be deployed on different frequency points, that is, base stations in different geographical locations work on different frequency points, so that the UE needs to send UL-signal in different time-frequency resources in different geographical locations.

[0284] Optionally, the first configuration information can further include a mapping relationship between the time-frequency resource for sending the UL-signal and the time-frequency resource for receiving the SSB. It can be understood that the UE can listen to the SSB based on the time-frequency resource of the SSB associated with the UL-signal after sending the UL-signal.

[0285] It should be noted that the time-frequency resource of the SSB can include one or more.

[0286] Optionally, the first configuration information can further include power information for sending the UL-signal, length of the timer, and maximum transmission times of the UL-signal. Here, the timer is used by the UE to determine whether to resend the UL-signal.

[0287] Optionally, the first configuration information can be configured in advance at the UE side. For example, the first configuration information can be configured in any of the following ways:

[0288] configured by a core network element in advance;

[0289] configured by a server;

[0290] configured by an access network element;

[0291] pre-configured on a SIM card or a terminal device;

[0292] specified by a protocol.

[0293] S2, the UE sends the UL-signal according to the first configuration information.

[0294] In some embodiments, the UE triggers the sending of the UL-signal according to a first condition. The first condition includes one or more of the following:

[0295] The UE is configured with one or more frequency point information;

[0296] The UE does not search for network signals on the frequency point corresponding to the one or more frequency point information.

[0297] It can be understood that if the network device is already in the state of sending the SSB, it is not necessary to trigger the sending of the UL-signal. In addition, if the UE cannot obtain the frequency point information, the UE cannot send the UL-signal.

[0298] Optionally, the UE can select the first frequency point information from the one or more frequency point information according to a first criterion, and transmit the UL-signal.

[0299] The first criterion comprises:

[0300] The first frequency point information is the frequency point information with the highest priority in the one or more frequency point information.

[0301] The channel quality detected by the UE on the frequency point associated with the first frequency point information satisfies a first threshold value.

[0302] The first frequency point information is the frequency point information of the service transmission to be initiated by the terminal device.

[0303] In S2, the UE transmits the UL-signal according to the first configuration information, which can include that the UE determines the time-frequency resource for transmitting the UL-signal according to the geographical position. Considering the difference in network deployment, base stations in different geographical areas can be deployed on different frequency points, so the UE can need to perform transmission on different time-frequency resources.

[0304] S3, the UE listens to the SSB.

[0305] After receiving the UL-signal, the network device triggers the SSB transmission. Correspondingly, the UE can listen to the SSB,

[0306] Optionally, the network device can further trigger other network devices to perform SSB transmission.

[0307] Optionally, the other network devices can be network devices in other TAs adjacent to the TA of the current network device.

[0308] It should be understood that when the UE accesses the first network device, the first network device is triggered to transmit the SSB. However, only triggering the first network to transmit the SSB, the UE cannot determine when to trigger the second network device to transmit the SSB, and such operation is also not conducive to reducing the access delay of the UE.

[0309] In the embodiments of the present application, after the network device receives the UL-signal, it can also notify the network devices in the adjacent TA area to transmit the SSB, so that after the UE enters the adjacent TA area and performs the TAU (TA update) process, the UE can receive the SSB and / or system message transmitted by the network devices in the adjacent TA, thereby quickly performing cell switching and reducing the access delay of the UE.

[0310] Optionally, the UE can listen to the SSB at the same time as transmitting the UL-signal, or staggered in time from the UL-signal, for example, listening to the SSB after a period of time after transmitting the UL-signal.

[0311] It should be noted that the monitoring of the SSB by the UE can be on one frequency point and time window, or on multiple frequency points and time windows. The time period, frequency point, and time window can be configured by the first configuration information.

[0312] It can be understood that the UE can monitor the SSB on limited time-frequency resources, thereby avoiding power waste.

[0313] S4, UE abnormal situation processing.

[0314] Optionally, the UE can start a timer when sending the UL-signal. The stop condition of the timer is that the UE receives the SSB. If the timer times out, the UE retransmits the UL-signal.

[0315] Optionally, the UE can increase the transmission power when retransmitting the UL-signal.

[0316] Optionally, if the number of transmissions of the UL-signal reaches the maximum number of transmissions, the UE no longer attempts to transmit the UL-signal on the selected frequency. The UE attempts to reselect other frequencies or RATs for transmission.

[0317] It can be understood that the flow triggered by the UL-signal needs to have a corresponding error handling mechanism to prepare for the case that the network does not successfully receive the UL-signal.

[0318] Embodiment two

[0319] Referring to FIG. 8, in this embodiment, the UE can receive the SSB sent by the network device.

[0320] It should be noted that the SSB can be sent by the network device in an always-on manner, or can be sent by the network device in a manner triggered by the UL-signal according to the embodiment one, and the sending manner of the SSB is not limited here.

[0321] The SSB or SIBx further contains configuration information (i.e., the fifth configuration information in the above), which can indicate at least one BW information associated with / for the SSB.

[0322] Optionally, the BW information can be configured by an absolute frequency, or can be configured by a frequency indicated by a certain numerology, and the embodiments of the present application do not limit this.

[0323] It should be understood that the use of SSBs can be extended from a single bandwidth to multiple bandwidths, thereby facilitating subsequent operations of the UE, i.e., DL reception and UL transmission operations from different bandwidths (the bandwidth in which the SSB is located or other bandwidths).

[0324] Optionally, the configuration information can include one or more of the following:

[0325] a maximum number of bandwidths;

[0326] a maximum number of frequency points;

[0327] a maximum number of carriers;

[0328] a maximum number of frequency domain resources;

[0329] service type information corresponding to each BW information;

[0330] a channel quality threshold associated with each BW information;

[0331] terminal device identity information corresponding to each BW information;

[0332] device group information corresponding to each BW information.

[0333] S2, the UE performs paging reception and / or UL-signal / RACH transmission according to the configuration information.

[0334] Optionally, the selection is performed according to at least one of the following factors:

[0335] a maximum number of bandwidths;

[0336] a maximum number of frequency points;

[0337] a maximum number of carriers;

[0338] a maximum number of frequency domain resources;

[0339] service type information;

[0340] identity information of the terminal device;

[0341] device group information of the terminal device;

[0342] capability information of the terminal device;

[0343] channel quality information.

[0344] Exemplarily, the UE selects different frequency resources for paging listening by performing a modulo operation on the UE ID with respect to the maximum number of frequency domain resources, or selects different bandwidth accesses according to the current triggered service according to the relevant information given by the configuration information, or selects different bandwidth accesses according to different channel quality information (obtained according to an SSB).

[0345] In this way, the system can distribute different services to different bandwidths, thereby balancing the load.
