FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

As shown in FIG. 1A , a communication system 100 includes a terminal 101 and a network device 102 .

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

In some embodiments, the access network device 102-1 is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved Node B (eNB), a next generation evolved Node B (ng-eNB), a next generation Node B (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

In some embodiments, the access network device 102-1 may be composed of a centralized unit (CU) and a distributed unit (DU), where the CU may also be referred to as a control unit. The CU-DU structure may be used to separate the protocol layers of the access network device, with some functions of the protocol layers being centrally controlled by the CU, and the remaining functions of some or all of the protocol layers being distributed in the DU, which is centrally controlled by the CU, but is not limited thereto.

In some embodiments, the core network device 102-2 may be a single device including one or more network elements, or may be multiple devices or a group of devices. The network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

In some embodiments, the technical solution of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

In some embodiments, the terminal 101 is connected to the core network device 102 - 2 through the access network device 102 - 1 .

It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, the fourth generation mobile communication system (4G), the fifth generation mobile communication system (5G), 5G new radio (NR), the sixth generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RA), and the like. The following technologies are used for the communication of wireless networks: IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20 (Ultra-WideBand), Bluetooth, Public Land Mobile Network (PLMN) networks, systems using other communication methods, and next-generation systems based on these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

In NR, the time domain timing of the Synchronization Signal Block (SSB) and system messages, such as System Information Block 1 (SIB1), is semi-statically configured. The periodic transmission of common signals (SSB/SIB1/cell-common physical downlink control channel PDCCH) limits network devices from using (deeper) sleep modes to save energy. Therefore, increasing the sleep time of network devices can be achieved through time-domain broadcast channel/signal adjustment schemes to save energy.

On-demand signaling in the time domain, such as on-demand SSB/SIB1, is one of the key candidate technologies. In on-demand SSB/SIB1, SSB/SIB1 is no longer sent periodically, but is instead sent based on terminal demand, as shown in Figure 1B.

In some embodiments, the network device may stop periodically sending SSB/SIB1, thereby being in a Network Energy Saving (NES) state, or use a sparser time domain pattern to send SSB/SIB1.

In some embodiments, when a terminal has an SSB/SIB1 requirement, it sends a wake-up signal (WUS) to the network device. After receiving the WUS, the network device sends SSB/SIB1, thereby entering the non-NES state. After sending one or more SSB bursts (SSB burst), the network device stops sending SSB/SIB1 and returns to the NES state, depending on the network service load, the number of resident terminals, the service type, the time period, etc.

Taking SSB as an example, after a network device transitions from the off state to the on state (i.e., after it resumes sending an SSB burst), it may selectively transmit some or all SSBs within the SSB burst based on request status, service conditions, and other factors. If this process were transparent to the terminal, the terminal might detect and receive the corresponding SSBs based on the protocol's predefined SSB pattern scenario. This would increase terminal implementation complexity, power consumption, and degrade measurement performance.

From another perspective, the current SSB pattern is mainly aimed at scenarios where network equipment periodically transmits SSB, and is determined based on factors such as the corresponding frequency band and subcarrier spacing (SCS).

In on-demand SSB scenarios, to further improve network energy savings while meeting terminal measurement and synchronization requirements, one possible approach is for network devices to frequently transmit the corresponding SSB within a certain period of time. To meet these requirements, a new SSB pattern can be considered.

The following first introduces the periodic transmission SSB.

An SSB occupies four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain. The SSB contains primary synchronization signals (PSS), secondary synchronization signals (SSS) and physical broadcast channel (PBCH).

The NR system supports five SSB time-domain transmission cases, namely, case A to case E, as shown in Figure 1C. The time-domain patterns of different cases depend on factors such as the SSB subcarrier spacing (SCS), operating frequency, and time division duplexing (TDD)/frequency division duplexing (FDD) standards. Different SSB cases correspond to the number of SSBs in an SSB burst and the time-domain resource position occupied within the SSB burst. The duration of an SSB burst is 5 milliseconds (ms). For example, the SSB transmission period is 20 ms. Furthermore, network devices can configure the SSB transmission period and time-domain pattern using the relevant information carried in SIB1. The maximum SSB transmission period is 160 ms.

Currently, SSBs must be sent periodically. Even when the number of terminals connected to a network device is small or the traffic load is extremely low, the network device still needs to periodically send SSBs to enable terminals to complete operations such as time-frequency synchronization, automatic gain control (AGC) settling, secondary cell activation, and obtain system information. The periodic mandatory transmission of downlink signals undoubtedly reduces the chances of network devices entering the sleep state, increases unnecessary energy consumption, and increases operating costs.

Table 1 provides the time domain resource ratios of SSB and SIB1 in different configuration/deployment scenarios.

Table 1

As can be seen from Table 1, the proportion of time domain resources can reach up to 17.14%. In this scenario, network devices will not have the opportunity to enter the sleep state, which greatly limits the use of energy-saving technologies by network devices and increases network operating costs.

Therefore, the present disclosure provides the following information transmission method, device, and storage medium, which, while meeting the terminal measurement and synchronization requirements, support flexible adjustment of the SSB transmission method in the NES mode, improve the availability of network energy saving, reduce the complexity of terminal implementation, and help save network energy consumption.

It should be noted that the present disclosure uses SSB as an example for explanation. Other periodically transmitted signals such as SIB1, paging messages, etc. can also be applicable to the scheme of the present disclosure, and the present disclosure does not limit this.

FIG2 is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information transmission method, which includes:

Step S2101, terminal 101 determines the SSB transmission mode.

In some embodiments, the terminal 101 may determine the transmission mode of the SSB based on the first condition.

In one example, the first condition may be used to determine that a transmission state of the SSB has changed.

Exemplarily, the first condition may be used to determine whether the transmission state of the SSB is changed from the stop transmission state to the transmission state, or from the transmission state to the stop transmission state.

Exemplarily, the first condition may be used to determine whether the transmission state of the SSB is changed from off to on, or from on to off.

In an example, the terminal 101 may determine the first condition in the following manner, but not limited to:

Method 1: determining the first condition based on the indication information sent by the network device 102.

Exemplarily, the network device 102 sends displayed indication information to the terminal 101, where the indication information is used to indicate the first condition.

For example, the indication information indicates the time slot index in which the transmission status of the SSB changes, and the terminal 101 determines that the transmission status of the SSB changes in the time slot.

Method 2: determining the first condition based on a predefined method.

For example, the first condition may be agreed upon by the protocol, for example, the time point corresponding to the transmission state of the SSB may be agreed upon. Assuming that the transmission state of the SSB is off from 2 a.m. to 4 a.m., the terminal 101 determines that the transmission state of the SSB is switched from on to off at 2 a.m., and determines that the transmission state of the SSB is switched from off to on at 4 a.m.

For example, a number n may be agreed upon by the protocol. When the terminal 101 attempts to receive the corresponding SSB and fails to receive the corresponding SSB in n consecutive SSB cycles, the terminal 101 determines that the SSB is in the off state. Conversely, if the terminal 101 receives the corresponding SSB in n consecutive SSB cycles, the terminal 101 determines that the SSB is in the on state.

In some embodiments, the terminal 101 may determine the transmission mode of the SSB based on the first condition described above when the transmission state of the SSB changes.

In some embodiments, the terminal 101 may determine the SSB transmission mode by using, but not limited to, one or more of the following methods:

Method 1: Determine the SSB transmission method through capability reporting.

In one example, the terminal 101 sends capability indication information to the network device 102, where the capability indication information is used to indicate the capability of the SSB transmission mode supported by the terminal 101.

Exemplarily, the capability indication information may be used to indicate at least one of the following:

a first duration associated with the SSB transmission;

a first number associated with the SSB transmission;

The maximum transmission period of the SSB;

The SSB pattern that the terminal expects to transmit;

The terminal expects the SSB density to be transmitted, the SSB density being used to indicate the maximum duration between the transmission of two adjacent SSBs, and/or the SSB density being used to indicate the maximum duration between the transmission of two adjacent SSB bursts;

The SSB index that the terminal expects to be transmitted.

Among them, the first duration can be used to indicate at least one of the following: the minimum duration of SSB transmission; the maximum duration of SSB transmission; the transmission duration of SSB expected by the terminal.

For example, the first duration can be selected from a plurality of candidate durations, assuming that the candidate durations are 1 millisecond (ms), 10 ms, and 20 ms, and the first duration is used to indicate the maximum duration of SSB transmission, and the maximum duration can be 10 ms. Exemplarily, the terminal expects to receive the SSB within the first duration.

In one example, the first duration may be associated with a second duration, wherein the second duration may be a duration during which the SSB is in a stop transmission state (or off state).

For example, if the SSB off duration is less than the first value, that is, the second duration is less than the first value, the terminal expects the first duration of SSB transmission to be equal to 1ms. If the second duration is greater than the second value, the terminal expects the first duration of SSB transmission to be equal to 10ms. The first value and the second value may be determined based on a predefined method and/or signaling indication, which is not limited in this disclosure.

In one example, the first duration may be unrelated to the second duration, that is, the first duration is decoupled from the second duration.

The first number may be used to indicate at least one of the following:

The maximum number of cycles corresponding to transmitting the SSB;

The minimum number of cycles corresponding to transmitting the SSB;

The maximum number of SSB burst transmissions corresponding to burst sets;

The minimum number of SSB burst transmissions;

The number of cycles corresponding to the SSB transmission expected by the terminal;

The number of SSB bursts that the terminal expects to transmit.

Exemplarily, the first number is used to indicate the maximum number N ₁ of cycles corresponding to the transmission of SSB, and the terminal 101 expects the network device 102 to transmit SSB for a maximum of N ₁ cycles.

Exemplarily, the first number is used to indicate the minimum number of cycles N ₂ corresponding to the transmission of SSB, and the terminal 101 expects the network device 102 to transmit SSB for at least N ₂ cycles.

Exemplarily, the first number is used to indicate the minimum number N ₃ corresponding to SSB burst transmissions, and the terminal 101 expects the network device 102 to transmit at least N ₃ SSB bursts.

Exemplarily, the first number is used to indicate the maximum number N ₄ corresponding to SSB burst transmissions, and the terminal 101 expects the network device 102 to transmit a maximum of N ₄ SSB bursts.

Exemplarily, the first number is used to indicate the number N ₅ of cycles corresponding to the SSB transmission expected by the terminal, and the terminal 101 expects the network device 102 to transmit N ₅ SSB cycles.

Exemplarily, the first number is used to indicate the number N ₆ of SSB bursts that the terminal expects to transmit, and the terminal 101 expects the network device 102 to transmit N ₆ SSB bursts.

The above-mentioned _N1 to _N6 can be positive integers, and the _N1 to _N6 are determined based on a predefined or signaling indication method.

The above is merely an exemplary description, and the present disclosure does not limit the specific content indicated by the first number.

Among them, the maximum transmission period of SSB can refer to the maximum value of the SSB transmission period expected by the terminal 101, assuming it is 10ms, and the maximum period length of the SSB transmission by the network device 102 is 10ms.

Of course, the capability indication information can also be used to indicate the minimum transmission period of SSB and/or the transmission period of SSB expected by terminal 101, which is not limited in this disclosure.

For example, the capability indication information is used to indicate that the minimum transmission period of SSB is 1ms, and the minimum period duration of SSB transmission by the network device 102 is 1ms.

The SSB pattern that the terminal 101 expects to transmit may be any of the following:

a first type of SSB pattern, where the first type of SSB pattern is the SSB pattern corresponding to the first mode;

The second type of SSB pattern is the SSB pattern corresponding to the network energy saving NES mode.

The first mode may be a non-NES mode, and the first type of SSB pattern may be an existing SSB pattern in the protocol, such as the SSB pattern shown in FIG. 1C or Table 1.

Exemplarily, the first type of SSB pattern can be the SSB pattern corresponding to caseA>3 gigahertz (GHz).

Among them, the second type of SSB pattern can be an SSB pattern newly added for the NES mode, which can be different from the first type of SSB pattern, that is, different from the SSB pattern shown in Figure 1C or Table 1.

Exemplarily, the SSB density that the terminal 101 expects to transmit can be measured based on the maximum duration between the transmission of two adjacent SSBs. For example, two adjacent SSBs can be separated by a maximum of m ₁ time units, and the time unit can be a time slot, a symbol, etc., which is not limited in this disclosure.

Exemplarily, the SSB density that the terminal 101 expects to transmit may be measured based on the minimum time interval between the transmission of two adjacent SSBs, for example, two adjacent SSB bursts may be separated by at least m ₂ time units.

Exemplarily, the density of SSBs that the terminal 101 expects to transmit may be measured based on the expected duration that the terminal expects to transmit two adjacent SSBs, for example, the terminal 101 expects that the interval between two adjacent SSBs is m ₃ time units.

Exemplarily, the SSB density that the terminal 101 expects to transmit can be measured based on the maximum duration between the transmissions of two adjacent SSB bursts. For example, two adjacent SSB bursts can be separated by a maximum of m ₄ time units.

Exemplarily, the SSB density that the terminal 101 expects to transmit may be measured based on the minimum length of time between the transmission of two adjacent SSB bursts. For example, two adjacent SSB bursts may be separated by at least m ₅ time units.

Exemplarily, the SSB density that the terminal 101 expects to transmit can be measured based on the expected duration that the terminal expects to transmit two adjacent SSB bursts, for example, the terminal 101 expects that the interval between two adjacent SSB bursts is m ₆ time units.

Wherein, _m1 to _m6 can be positive integers.

Exemplarily, the SSB density that the terminal 101 expects to transmit may also be measured based on the SSB transmission period, which is not limited in the present disclosure.

Exemplarily, the terminal 101 may inform the network device 102 of the SSB index to be transmitted through capability indication information.

For example, the SSB burst corresponds to 8 SSB cycles, and the terminal 101 sends capability indication information to the network device 102, indicating that the SSB index (index) that the terminal 101 expects to transmit is the first 4 SSBs, for example {0, 1, 2, 3}.

In an example, the capability indication information may be defined based on different cases. For example, different cases correspond to different capability indication information, that is, different cases correspond to different SSB transmission modes.

For example, a case may include but is not limited to at least one of the following:

Frequency band of the terminal;

Frequency range of the terminal;

subcarrier spacing;

The carrier where the terminal is located;

The duplex system used in the community;

The first type of case is a case under the first mode;

The second type of case is the case in NES mode.

The frequency range of the terminal may be less than 3 GHz or greater than 3 GHz.

The duplex mode adopted by the cell includes but is not limited to TDD and/or FDD.

The first mode may be a non-NES mode, and the first type of case may be any one of case A to case E in Table 1.

The second type of case may be a special case in the NES mode, and illustratively, may be different from the aforementioned case A to case E.

It is understandable that the capability indication information may not be defined based on a case. For example, regardless of the case, the capability indication information may indicate the same or different content.

In some embodiments, the terminal 101 sends capability indication information to the network device 102 and can determine the time-frequency domain resources for SSB transmission based on the indication information sent by the network device 102.

The indication information may be used to indicate at least one of the following:

A first time window, where the first time window is a time window for the SSB transmission, and a duration of the first time window is a first duration;

a first number associated with the SSB transmission;

The maximum transmission period of the SSB;

SSB pattern;

The density of the SSB is used to indicate the maximum duration between the transmission of two adjacent SSBs, and/or the density of the SSB is used to indicate the maximum duration between the transmission of two adjacent SSB bursts;

SSB index transmitted within the SSB burst.

The content of the indication information may be determined based on the capability indication information reported by the terminal 101. For example, if the capability indication information reported by the terminal 101 indicates a first duration, and the first duration is used to indicate the maximum duration of the expected SSB transmission, then the first duration of the first time window indicated by the indication information sent by the network device 102 may be less than or equal to the maximum duration.

For another example, the capability indication information reported by the terminal 101 indicates a first number, which is used to indicate the number of cycles corresponding to the SSB transmission expected by the terminal. The first number indicated in the indication information sent by the network device 102 can be equal to the number of cycles corresponding to the SSB transmission expected by the terminal.

For another example, the capability indication information reported by the terminal 101 indicates the SSB pattern, SSB density and/or SSB index expected to be transmitted, and the indication information sent by the network device 102 may indicate the SSB pattern, SSB density and/or SSB index expected to be transmitted by the terminal.

The above is merely an exemplary description. Any scheme in which the network device 102 sends indication information to the terminal 101 based on the capability indication information so that the terminal 101 determines the transmission mode of SSB should fall within the scope of protection of this disclosure.

The network device 101 sends indication information to indicate the implementation process of the SSB transmission method. The implementation process can refer to the subsequent method three and will not be introduced here.

Method 2: Determine the SSB transmission method based on a predefined method.

The predefined method may be agreed upon in a protocol, and this disclosure does not limit this.

In one example, determining the transmission mode of the SSB based on the predefined mode may include but is not limited to at least one of the following:

Determining, based on a predefined manner, a first duration expected by the terminal, where the first duration is associated with the SSB transmission;

Determining, based on a predefined manner, a first number expected by the terminal, the first number being associated with the SSB transmission;

Determining, based on a predefined method, a maximum transmission period during which the terminal expects to transmit an SSB;

Determining, based on a predefined method, an SSB pattern that the terminal expects to transmit;

Determining, based on a predefined method, a density of SSBs that the terminal expects to transmit, where the density of the SSBs is used to indicate a maximum duration between transmissions of two adjacent SSBs, and/or, the density of the SSBs is used to indicate a maximum duration between transmissions of two adjacent SSB bursts;

Based on a predefined method, determine the SSB index that the terminal expects to transmit.

Among them, the specific contents of the first duration, the first number, the maximum transmission period of SSB, SSB pattern, SSB density, and SSB index have been introduced in the previous embodiments and will not be repeated here.

Exemplarily, the predefined rules may be defined based on different cases, or may not be defined based on cases. The contents included in the cases are similar to those in the aforementioned embodiment and will not be described in detail here.

In some embodiments, after the terminal 101 and the network device 102 determine at least one of the first duration, the first number, the maximum transmission period of the SSB, the SSB pattern, the SSB density, and the SSB index that the terminal expects to transmit based on a predefined method, the network device 102 may send an indication message. At this time, the indication message may be used to determine one of the transmission modes for the terminal 101 from a plurality of predefined SSB transmission modes, or to confirm the predefined transmission mode. This disclosure is not limited to this.

The network device 101 sends indication information to indicate the implementation process of the SSB transmission method. The implementation process can refer to the subsequent method three and will not be introduced here.

Method three: the network device 102 sends indication information, and the terminal 101 determines the SSB transmission method based on the indication information.

In an example, the indication information may be used to indicate at least one of the following:

A first time window, where the first time window is a time window for the SSB transmission, and a duration of the first time window is a first duration;

a first number associated with the SSB transmission;

The maximum transmission period of the SSB;

SSB pattern;

The density of the SSB is used to indicate the maximum duration between the transmission of two adjacent SSBs, and/or the density of the SSB is used to indicate the maximum duration between the transmission of two adjacent SSB bursts;

SSB index transmitted within the SSB burst.

Exemplarily, the first time window is the time window for actually transmitting SSB configured by the network device 102 for the terminal 101, wherein the duration of the first time window may be the first duration.

Exemplarily, the network device 102 may indicate to the terminal 101 via a first number that it is monitoring SSB or SSB burst.

Exemplarily, the first number is used to indicate the maximum number of cycles N corresponding to the transmission of the SSB. The terminal 101 needs to continuously monitor the time-frequency domain resource positions corresponding to N SSB transmission cycles and attempt to receive the SSB.

Exemplarily, the network device 102 may indicate the maximum transmission period, minimum transmission period, etc. of the SSB that the terminal 101 needs to monitor through indication information.

Exemplarily, the indication information may indicate an SSB pattern, and the terminal 101 monitors the SSB based on the SSB pattern.

Exemplarily, the indication information indicates the density of the actually transmitted SSB, and the terminal 101 can monitor the SSB and/or SSB burst based on the density of the SSB.

Exemplarily, the indication information may be used to indicate the SSB index actually transmitted within the SSB burst.

For example, the SSB burst corresponds to 8 SSB cycles, the SSB index indicated by the indication information is {0, 1, 2, 3}, and the terminal 101 determines that the first 4 SSBs are transmitted.

Exemplarily, the indication information may be indicated based on different cases or may not be indicated based on case. The content included in the case is similar to that in the aforementioned embodiment and will not be repeated here.

In one example, the network device 102 may send a first message to the terminal 101 , including the above-mentioned indication information.

Exemplarily, the first message may be any of the following:

Downlink Control Information (DCI);

Media Access Control Element (MAC CE)

Radio Resource Control (RRC) message.

Exemplarily, the above content may be indicated in the first message in the following manner:

Bitmap method;

Indicates a transmission mode in the SSB transmission mode set.

Exemplarily, when the first message indicates the above content in a bitmap manner, the indication can be performed with SSB burst or SSB transmission period as the granularity.

For example, SSB burst corresponds to 8 SSB transmission cycles, where SSB is transmitted in cycles 1 and 2. The bitmap can be 11000000.

For another example, if the first 4 SSBs are transmitted in the SSB transmission cycle, the bitmap may be 11110000.

Exemplarily, the above contents indicated by the indication information can be combined to obtain an SSB transmission mode set, which includes multiple SSB transmission modes, and the network device 102 can indicate the index of one of the SSB transmission modes.

For example, the SSB transmission mode set includes 8 SSB transmission mode sets, the index of the SSB transmission mode indicated by the network device 102 through the first message is 2, and the terminal 101 determines SSB transmission mode #2 in the SSB transmission mode set as the actual SSB transmission mode.

In one example, the network device 102 may carry the indication information through a reserved information field in the first message.

Taking the first message as DCI as an example, such as the reserved bits carried by DCI format 1_0, DCI format 1_0 can be scrambled based on the system information radio network temporary identifier (System Information-Radio Network Temporary Indentifier, SI-RNTI), or based on the random access radio network temporary identifier (Random Access-Radio Network Temporary Indentifier, RA-RNTI), or based on the temporary cell radio network temporary identifier (Temporary Cell-Radio Network Temporary Indentifier, TC-RNTI).

Exemplarily, the indication information may be carried on a new RNTI-scrambled DCI, for example, NES-RNTI-scrambled DCI format 1_0.

Exemplarily, the above-mentioned DCI can be based on an existing common search space (CSS) configuration, such as SS#0 configuration.

Exemplarily, the indication information may be carried based on the new format DCI.

The above description is merely an exemplary description, and the present disclosure does not limit the scheme of the first message carrying the indication information.

In some embodiments, the terminal 101 sends capability indication information to the network device 102 , and the network device 102 determines the content of the indication information based on the terminal capability and a predefined case.

For example, the terminal reports the minimum duration of SSB transmission expected by the terminal 101 through the capability indication information, and the network device 102 indicates the actual duration of the SSB transmission through the indication information.

In some embodiments, the terminal 101 may determine the transmission mode of the SSB based on a combination of one or more of the above methods.

In addition, terminal 101 can determine the SSB pattern based on existing mechanisms.

For example, terminal 101 may determine an SSB pattern based on different cases. The correspondence between cases and SSB patterns is determined by an existing protocol.

In some embodiments, terminal 101 may determine the SSB transmission mode based on one or more combinations of the above methods. In addition, terminal 101 may also need to determine the SSB pattern.

In one example, terminal 101 may determine the SSB pattern to be transmitted based on the number of SSBs included in the SSB burst.

In one example, terminal 101 may determine the transmitted SSB pattern based on the time domain position of the SSB transmitted within the SSB burst.

In one example, terminal 101 may case determine the SSB pattern of the transmission.

Among them, a case under the NES scenario, that is, the second type of case, can be added to the protocol.

The second type of Case may include, for example, SCS, frequency range, frequency band such as FR1/FR2, duplex mode adopted by the cell, etc. The specific content has been introduced in the previous embodiment and will not be repeated here.

In step S2102, the network device 102 determines the SSB transmission mode.

In some embodiments, the terminal 101 reports the capability indication information in mode 1, and the network device 102 may configure the SSB transmission mode for the terminal 101 based on the capability indication information and inform the terminal 101 through the indication information. Alternatively, the network device 102 may not send the indication information and adopt the SSB transmission mode indicated by the capability indication information by default.

In some embodiments, the terminal 101 determines the transmission mode of the SSB using the second method, and the network device 102 may also determine the transmission mode of the SSB based on the predefined rules. The network device 102 may also send an indication message after determining the transmission mode of the SSB based on the predefined rules, thereby informing the terminal 101 of the final transmission mode of the SSB.

In some embodiments, corresponding to the above-mentioned method three, the network device 102 directly determines the transmission mode of SSB and sends indication information to the terminal 101.

Among them, the network device 102 determines the transmission method of SSB is similar to the terminal side's determination of the transmission method of SSB, which will not be repeated here.

Step S2103, the network device 102 sends SSB to the terminal 101.

In some embodiments, the network device 102 sends SSB to the terminal 101 based on the transmission mode.

In some embodiments, terminal 101 receives the SSB based on the corresponding transmission.
