[0084] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 , wherein the network device includes at least one of the following: an access network device and a core network device.

[0085] 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.

The network element 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), and a Next Generation Core (NGC).

[0088] In some embodiments, the technical solution of the present disclosure can be applied 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 can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0089] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0090] 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.

[0091] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are 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.

[0092] 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, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0093] In some embodiments, in a scenario where a network device communicates with a terminal, the network device may send a synchronization broadcast signal block (SS (Synchronization Signal) and PBCH (Physical Downlink Broadcast Channel) Block, SSB) to the terminal.

[0094] Among them, the network device can send SSB to the terminal based on the SSB transmission mode, and the terminal can receive the SSB sent by the network device based on the SSB transmission mode.

[0095] In some embodiments, the network device may adjust the SSB transmission mode for some needs.

[0096] For example, when a network device is about to enter a Network Energy Saving (NES) mode or is in the NES mode, the SSB transmission mode may be adjusted for energy saving purposes.

[0097] In some embodiments, when the terminal has not yet determined the SSB transmission mode, it needs to determine the SSB transmission mode so that it can receive SSB according to the SSB transmission mode. When the terminal has determined the SSB transmission mode, if the network device adjusts the SSB transmission mode, the terminal needs to determine the adjusted SSB transmission mode.

[0098] Therefore, how the terminal determines the SSB transmission mode so as to smoothly receive SSB according to the SSB transmission mode is a technical problem that needs to be solved urgently.

[0099] FIG2 is an interactive schematic diagram showing a method for receiving information according to an embodiment of the present disclosure.

[0100] As shown in FIG2 , the information receiving method may include the following steps:

[0101] In step S201, the terminal determines the SSB transmission mode of the synchronous broadcast signal block according to a predefined method, or determines the SSB transmission mode according to the first indication information of the network device.

[0102] In some embodiments, the SSB transmission mode satisfies the first condition.

[0103] For example, a first condition may be defined based on a predefined manner, for example, the first condition defined in the predefined manner is that the SSB period is equal to an integer multiple of the first duration, or the SSB period is equal to the first duration, and the duration candidate set in which the first duration exists is {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. The terminal determines the SSB transmission mode according to the predefined manner, which may include the terminal determining the SSB transmission mode when the SSB transmission mode satisfies the first condition. For example, when the first condition defined in the predefined manner is that the SSB period is equal to an integer multiple of the first duration, and the duration candidate set in which the first duration exists is {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, the terminal selects a duration as the SSB period from the duration candidate set of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms} based on implementation, and then attempts to receive the SSB according to the SSB period.

[0104] For example, when the SSB transmission mode satisfies the first condition, the terminal determines the SSB transmission mode according to a predefined method, which may mean that the SSB transmission mode determined by the terminal according to the predefined method satisfies the first condition.

[0105] In step S202, the terminal receives the SSB sent by the network device according to the SSB transmission mode.

[0106] It should be noted that the SSB transmission mode and the SSB configuration may be the same or different. When the terminal has not yet determined the SSB configuration, or does not know the adjusted SSB configuration, the terminal may also determine the SSB transmission mode based on the embodiments of the present disclosure, and then receive the SSB according to the SSB transmission mode.

[0107] For example, taking the SSB period as an example, the SSB period in the SSB configuration can be 40ms, and the SSB period in the SSB transmission mode can be 20ms. Then the network device actually sends SSB with a period of 40ms, and the terminal monitors SSB according to a monitoring period of 20ms. Since 40ms is an integer multiple of 20ms, the terminal can still receive part of the SSB.

[0108] For example, the terminal determines the SSB transmission mode according to the first indication information of the network device, which may be the same as the SSB configuration of the network device actually sending the SSB. The SSB transmission mode determined by the terminal according to the predefined method may be the same as or different from the SSB configuration of the network device actually sending the SSB.

[0109] In some embodiments, the terminal determines the SSB transmission mode according to a predefined method, including at least one of the following:

[0110] When the terminal has not yet determined the SSB transmission mode, the terminal determines the SSB transmission mode according to a predefined method;

[0111] When the terminal has determined the first SSB transmission mode, it determines the adjusted SSB transmission mode according to a predefined method. For example, the adjusted configuration can be called the second SSB transmission mode.

[0112] It should be noted that, when the terminal determines the adjusted SSB transmission mode according to a predefined method, the terminal can determine whether the network device adjusts the SSB transmission mode through signaling instructions or predefined methods. For example, the network device can indicate to the terminal that the SSB transmission mode is to be adjusted or has been adjusted, and can also indicate the time for the terminal to adjust the SSB transmission mode; for example, the terminal can determine whether the network device adjusts the SSB transmission mode based on the monitoring result of the SSB. For example, the terminal monitors the SSB in the first monitoring cycle, and can monitor 1 SSB in each monitoring cycle, but within a period of time (such as network instructions or protocol agreements), the terminal can only monitor 1 SSB every two monitoring cycles, then the terminal can determine that the network device has adjusted the SSB transmission mode.

[0113] In some embodiments, when the terminal determines the SSB transmission mode according to a predefined method, the network device can also determine the SSB transmission mode according to a predefined method, so that the network device and the terminal can reach a consensus on the SSB transmission mode, thereby ensuring that when the network device sends the SSB to the terminal according to the SSB transmission mode, the terminal can smoothly receive the SSB sent by the network device according to the SSB transmission mode.

[0114] In some embodiments, the terminal may determine the transmission mode of the corresponding SSB based on the indication information on the network side. The first indication information for indicating the SSB transmission mode may include at least one of the following:

[0115] Radio Resource Control (RRC) signaling;

[0116] Downlink Control Information (DCI);

[0117] Media Access Control Control Element (MAC CE).

[0118] It should be noted that the first indication information is not limited to the above-mentioned RRC signaling, DCI, MAC CE, etc., but may also include other information, such as system information, system information block (System Information Block, SIB (such as SIB1 or other SIBs, such as SIBn)), paging message, etc.

[0119] In some embodiments, the terminal determines the SSB transmission mode according to the first indication information of the network device, including at least one of the following:

[0120] When the terminal has not yet determined the SSB transmission mode, determining the SSB transmission mode according to the first indication information of the network device;

[0121] When the terminal has determined the first SSB transmission mode, the configuration adjusted according to the first indication information of the network device, for example, the adjusted configuration can be called the second SSB transmission mode.

[0122] According to the embodiments of the present disclosure, it is possible to ensure that, when the SSB transmission mode has not yet been determined, the terminal can determine the SSB transmission mode according to a predefined method, or determine the SSB transmission mode according to the first indication information of the network device. Furthermore, it is possible to ensure that, when the SSB transmission mode has been determined, the terminal can determine the adjusted SSB transmission mode according to the predefined method, or determine the adjusted SSB transmission mode according to the first indication information of the network device. Thus, the terminal can smoothly receive the SSB sent by the network device according to the SSB transmission mode.

[0123] In some embodiments, when adjusting the SSB transmission mode, one possible implementation scenario is that the adjustment method is transparent to the terminal, that is, the terminal is not aware of the adjustment method. The terminal receives SSBs based on a predefined assumption, e.g., a 20ms listening period, and based on the SSB transmission mode notified by system information (e.g., SIB1) and / or RRC signaling. In this scenario, to avoid affecting the terminal's cell search, measurement, and other processes, the SSB transmission mode must meet the first condition.

[0124] Correspondingly, based on its own cell search, measurement, time and frequency synchronization requirements, the terminal expects the SSB transmission mode transmitted by the network device to meet the first condition.

[0125] Under the condition that the adjustment method is transparent to the terminal, the terminal can attempt to monitor the SSB based on the assumed transmission mode, e.g., a monitoring period of 20ms, and the SSB pattern determined based on the scenario in which the terminal is located (e.g., any one of case A to case E in the subsequent embodiments); it can also attempt to monitor the SSB based on the SSB transmission mode determined by the existing signaling mechanism, e.g., SIB1 or RRC; it can also attempt to monitor the SSB based on the SSB period, SSB pattern, actually transmitted SSB index, etc. defined by the first condition, and the present invention does not impose any restrictions on this.

[0126] In some embodiments, in the case of adjusting the SSB transmission mode, another possible implementation scenario is that the adjustment method is notified to the terminal by signaling. In the traditional mechanism, the SSB transmission mode is notified to the terminal based on SIB1 or RRC signaling. In the NES scenario, the network device can choose to reuse the existing signaling mechanism, or introduce a new signaling mechanism to notify the terminal of the corresponding SSB transmission mode. Taking into account that the SSB transmission is cell-specific transmission, in order to reduce the impact of legacy terminals, an additional SSB transmission pattern can be introduced for the NES terminal, or the NES terminal and the legacy terminal can share the SSB transmission pattern. Similarly, in order to avoid affecting the terminal's cell search, measurement and other processes, and to avoid affecting the legacy terminal, the SSB transmission mode must meet the first condition.

[0127] Correspondingly, the terminal determines the SSB transmission mode based on the indication signaling and receives the corresponding SSB. The terminal side expects the SSB transmission mode to meet the first condition based on its own cell search, measurement, time-frequency synchronization and other requirements.

[0128] In some embodiments, the SSB transmission mode includes at least one of the following:

[0129] SSB period; for example, the SSB period may be equal to the time domain interval of adjacent SSB burst sets, or the SSB period may be equal to the time domain interval of the SSBs actually transmitted in adjacent SSB burst sets, or the SSB period may be equal to the time domain interval of the SSBs of the same index actually transmitted, or the SSB period may be equal to the time domain interval of the SSB burst sets in which the SSBs of the same index actually transmitted are located.

[0130] The pattern of SSB; for example, the pattern of SSB can represent the time domain position of the SSB burst set in which the SSB is located within a unit time length (such as one frame or half a frame), and / or the SSB candidate position or the actual position of the SSB in the SSB burst set.

[0131] Time domain resources of SSB;

[0132] Frequency domain resources of SSB;

[0133] The period of the SSB burst set in which the SSB is located;

[0134] The SSB actually transmitted in the SSB burst set may be represented, for example, by an SSB index;

[0135] The time domain position of the SSB burst set.

[0136] In some embodiments, when the network device is about to enter the NES mode or is in the NES mode, the network device determines the adjusted SSB transmission mode according to a predefined method, or indicates the adjusted SSB transmission mode to the terminal through the first indication information.

[0137] In the embodiments of the present disclosure, a terminal that can determine the SSB transmission mode of the synchronous broadcast signal block according to a predefined method, or determine the SSB transmission mode according to the first indication information of the network device, is a terminal that can support the NES mode (for example, it can be called an NES terminal), while a legacy terminal is a terminal that does not support the NES mode. The legacy terminal cannot determine the SSB transmission mode of the synchronous broadcast signal block according to the predefined method based on the embodiments of the present disclosure (for example, the predefined method is agreed upon by the protocol, and the legacy terminal does not support the predefined method agreed upon by the protocol), or determine the SSB transmission mode according to the first indication information of the network device (for example, the legacy terminal cannot receive the first indication information, or cannot parse the first indication information).

[0138] In order to receive SSB, both NES terminals and traditional terminals need to determine the SSB transmission mode, and the transmission of SSB is cell-specific. For example, the network side sends SSB to all service users in the cell.

[0139] Since both NES terminals and traditional terminals can exist in a cell, the terminals in the cell can attempt to receive SSB based on the assumed SSB transmission mode. For example, if the assumed SSB transmission mode is a 20-ms listening period, the terminal can listen to SSB according to a 20-ms period. When the network device adjusts the SSB transmission mode, the adjusted SSB transmission mode must meet the first condition so that the adjusted SSB transmission mode is suitable for both NES terminals to receive SSB and traditional terminals to receive SSB, avoiding the situation where the adjusted SSB transmission mode is only suitable for NES terminals to receive SSB, but will cause traditional terminals to be unable to receive SSB. In addition, it can avoid introducing unnecessary SSB patterns to NES terminals, which increases the complexity of terminal reception of SSB.

[0140] It should be noted that, for traditional terminals, the network device may also send a second indication message to indicate the SSB transmission mode to the traditional terminal. In the embodiment of the present disclosure, the first indication message used to indicate the SSB transmission mode to the NES terminal, for example, the first indication message may include an ssb-PositionsInBurst IE, and the IE (Information Element) may be based on SIB1 or RRC signaling. The second indication information may also be reused, or newly introduced indication information may be used. For example, the newly introduced indication information may include at least one of the following: a new IE in RRC signaling, a new information field in DCI, or a DCI in a new format.

[0141] The first condition is illustrated below through several embodiments.

[0142] In some embodiments, the first condition includes at least one of the following:

[0143] SSB cycle conditions;

[0144] The condition of SSB in the SSB burst set where SSB is located;

[0145] Time domain location conditions for SSB burst sets.

[0146] In some embodiments, an SSB burst set may include one or more SSB candidate positions, for example, an SSB burst set may include 8 SSB candidate positions, or may include 4 SSB candidate positions. The SSB candidate positions in the SSB burst set may be determined based on a traditional mechanism (for example, based on the SSB pattern in case A to case E scenarios in subsequent embodiments), or may be determined based on the time domain position and / or frequency domain position in the SSB burst set characterized by the newly defined SSB pattern at which the SSB can be transmitted.

[0147] For example, for an SSB burst set, the SSB may be transmitted at each SSB candidate position, or the SSB may be transmitted at some of the SSB candidate positions.

[0148] For example, for multiple SSB burst sets, the SSB candidate positions for transmitting the SSBs may be the same, or the SSB candidate positions for transmitting the SSBs may be different.

[0149] In some embodiments, the SSB cycle condition includes at least one of the following:

[0150] The SSB period is equal to an integer multiple of the first duration;

[0151] The SSB period is greater than the second duration;

[0152] The SSB period is equal to the second duration;

[0153] The SSB period is less than the second duration.

[0154] In some embodiments, the first duration may be determined based on at least one of the following:

[0155] capability information reported by the terminal;

[0156] Indicative information for network devices;

[0157] Information agreed upon in the agreement.

[0158] In some embodiments, the first duration includes at least one of the following: 5 milliseconds; 20 milliseconds.

[0159] For example, the first duration may include one of a duration candidate set, for example, the duration candidate set is {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, where the duration in the duration candidate set may be the terminal's SSB monitoring period.

[0160] FIG3A is a schematic diagram showing a first duration according to an embodiment of the present disclosure.

[0161] In some embodiments, during the cell search phase, when attempting to receive an SSB, the terminal may monitor the SSB with a first duration (eg, 20 ms) as a period.

[0162] During this process, the network device needs to adjust the SSB period for energy saving considerations. In order to ensure that both the NES terminal and the traditional terminal can receive the SSB, the adjusted SSB period is equal to an integer multiple of the first duration.

[0163] As shown in FIG3A , for example, the SSB period before adjustment is 20 ms, and both the NES terminal and the traditional terminal can monitor the SSB according to the 20 ms period.

[0164] Based on the embodiments of the present disclosure, the NES terminal determines the adjusted SSB transmission mode according to a predefined method, or determines the adjusted SSB transmission mode according to the first indication information of the network device. However, based on the embodiments of the present disclosure, a traditional terminal cannot determine the adjusted SSB transmission mode according to a predefined method, or determine the adjusted SSB transmission mode according to the first indication information of the network device.

[0165] To ensure that both the NES terminal and the traditional terminal can receive the SSB after adjusting the SSB period, the SSB period may be adjusted to an integer multiple of 20 ms, for example, to 40 ms as shown in FIG. 3A .

[0166] The NES terminal determines the adjusted SSB transmission mode in a predefined manner, or determines the adjusted SSB transmission mode according to the first indication information of the network device, thereby determining that the adjusted SSB period is 40ms, and monitoring the SSB according to the 40ms monitoring period, and can successfully receive the SSB.

[0167] Since the traditional terminal cannot determine the adjusted SSB transmission mode according to the predefined method based on the embodiment of the present disclosure, or determine the adjusted SSB transmission mode according to the first indication information of the network device, it still monitors the SSB according to the SSB transmission mode before the adjustment (for example, according to the 20ms monitoring period). Since the adjusted SSB period is 40ms, the traditional terminal can also monitor the SSB according to the 20ms monitoring period.

[0168] Accordingly, when the network device adjusts the SSB transmission mode, by setting the SSB transmission mode to meet the first condition, it is ensured that both the NES terminal and the traditional terminal can receive SSB.

[0169] In some embodiments, when the terminal is in a connected state, if the SSB transmission mode has not yet been determined, when attempting to receive the SSB, the terminal can monitor the SSB with a first duration (e.g., 5 ms) as a period.

[0170] During this process, the network device needs to adjust the SSB period for energy-saving considerations. In order to ensure that both NES terminals and traditional terminals can receive SSB, the adjusted SSB period is equal to an integer multiple of 5 milliseconds, for example, adjusted to 20 milliseconds. NES can determine that the adjusted SSB period is 20ms, and monitor SSB according to a 20ms monitoring period, and can successfully receive SSB. Since traditional terminals cannot determine the adjusted SSB transmission mode, they still monitor SSB according to the SSB transmission mode before adjustment (for example, according to a 5ms monitoring period). Since the adjusted SSB period is 20ms, traditional terminals can also monitor SSB according to a 5ms monitoring period.

[0171] FIG3B is a schematic diagram showing another first duration according to an embodiment of the present disclosure.

[0172] The scenario shown in FIG3A is a scenario where the network device extends the SSB period for energy saving considerations. However, the embodiments of the present disclosure are not limited to the scenario shown in FIG3A and can also be applied to other scenarios.

[0173] For example, the network device may adjust the SSB transmission mode only within the first time range for some considerations, and continue to send SSB using the SSB transmission mode before adjustment outside the first time range.

[0174] As shown in FIG3B , the network device may increase the frequency of SSB transmission within the first time range (for example, the network device may increase the frequency of SSB transmission so that the terminal can complete the synchronization operation as quickly as possible), and then the SSB period is shortened within the first time range.

[0175] In this case, two SSB periods may be introduced, for example, the SSB period before adjustment is a default SSB period, and the SSB period after adjustment is an additional SSB period.

[0176] As shown in FIG3B , the preset SSB period is 80 ms and the additional SSB period is 20 ms.

[0177] The NES terminal determines the adjusted SSB transmission mode in a predefined manner, or determines the adjusted SSB transmission mode according to the first indication information of the network device, thereby determining that the adjusted SSB period is 20ms. Within the first time range, the SSB can be successfully received by monitoring the SSB according to the 20ms monitoring period. Outside the first time range, the SSB can be successfully received by receiving the SSB according to the 80ms monitoring period.

[0178] Since the traditional terminal cannot determine the adjusted SSB transmission mode according to the predefined method based on the embodiment of the present disclosure, or determine the adjusted SSB transmission mode according to the first indication information of the network device, it monitors the SSB according to the SSB transmission mode before the adjustment (for example, according to the monitoring period of 80ms) both within the first time range and outside the first time range. Although the adjusted SSB period is 20ms, the SSB period only within the first time range is 20ms, and the period outside the first time range is still 80ms, so the traditional terminal can still monitor most of the SSB according to the monitoring period of 80ms, so it will not have a significant impact on the traditional terminal's monitoring of SSB.

[0179] In some embodiments, the duration candidate set is, for example, {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. This duration candidate set may be a traditional duration candidate set, wherein the upper limit is 160ms. In the embodiments of the present disclosure, the SSB period may be determined within this duration candidate set. For example, if the second duration is 160ms, the SSB period may be less than or equal to the second duration. However, the SSB period is not limited to being determined within this duration candidate set. For example, the SSB period may also be greater than the second duration, such as 160ms.

[0180] In some embodiments, the period condition of the SSB burst set may be similar to the SSB period condition. For example, the period of the SSB burst set satisfies at least one of the following:

[0181] The period of the SSB burst set is equal to an integer multiple of the first duration;

[0182] The period of the SSB burst set is greater than the second duration;

[0183] The period of the SSB burst set is equal to the second duration;

[0184] The period of the SSB burst set is less than the second duration.

[0185] In some embodiments, the conditions of SSB in the SSB burst set include:

[0186] The period of the SSB corresponding to the first index of the SSB or the first beam in the SSB burst set is less than or equal to the first number of SSB burst set periods.

[0187] In some embodiments, the SSB of the first index may be an SSB of a specific index in the SSB burst set, or an SSB of any index in the SSB burst set, or an SSB of all indexes in the SSB burst set.

[0188] In some embodiments, the SSB corresponding to the first beam may be the SSB corresponding to a specific beam, or the SSB corresponding to any beam, or the SSB corresponding to all beams.

[0189] In some embodiments, since an SSB burst set may include one or more SSBs, when the SSBs in adjacent SSB burst sets are different, the network device needs to send multiple SSB burst sets to complete the sending of all SSBs.

[0190] For beam pairing, the terminal must match SSBs with beams. The terminal must receive each SSB (for example, through beam sweeping) to determine the most suitable beam for communication. This allows the terminal to use the most suitable beam to communicate with network devices, such as access network devices. Therefore, if the period of the first-indexed SSB in the SSB burst set or the SSB corresponding to the first beam is too large, the terminal will have to wait a long time before beam pairing is completed, causing significant delays in terminal communications.

[0191] Therefore, in an embodiment of the present disclosure, the first condition satisfied by the SSB transmission mode may include that the period of the SSB of the first index in the SSB burst set or the SSB corresponding to the first beam is less than or equal to the first number of SSB burst set periods, thereby avoiding the SSB period being too large, which causes the terminal to wait for a long time to receive each SSB.

[0192] In some embodiments, the network device completes the transmission of the SSB corresponding to each beam within a first number of SSB burst set periods.

[0193] In some embodiments, the first number is equal to the number of SSBs in the SSB burst set.

[0194] FIG3C is a schematic diagram showing an SSB burst set according to an embodiment of the present disclosure.

[0195] As shown in Figure 3C, for example, an SSB burst set includes 4 SSB candidate positions. The SSBs that need to be sent at the 4 SSB candidate positions are SSB with an index of 0 (SSB#0, for example, corresponding to beam#0), SSB with an index of 1 (SSB#1, for example, corresponding to beam#1), SSB with an index of 2 (SSB#2, for example, corresponding to beam#2), and SSB with an index of 3 (SSB#3, for example, corresponding to beam#3). For energy saving reasons, the network device only sends 1 SSB in each SSB burst set. Therefore, in order to send 4 SSBs, 4 SSB burst sets need to be sent. That is, the network device completes the transmission of the SSBs corresponding to the 4 beams within the 4 SSB burst set period.

[0196] In this case, the period of the SSB corresponding to the first index of the SSB or the first beam in the SSB burst set is less than or equal to four SSB burst set periods. For example, taking SSB#0 as an example, in Figure 3C, SSB#0 is sent in the first SSB burst set period and in the fifth SSB burst set period, so the period of SSB#0 is four SSB burst set periods. This ensures that the terminal completes the reception of SSB#0, SSB#1, SSB#2, and SSB#3 within the SSB burst set period, avoiding an excessively long SSB period that would cause the terminal to wait for a long time to receive each SSB.

[0197] In some embodiments, the network device may indicate which SSB to transmit in a SSB burst set during an SSB cycle through a bitmap or index.

[0198] For example, in the embodiment shown in FIG3C , the network device may indicate that the SSB index in the first SSB burst set period is 0, the SSB index in the second SSB burst set period is 1, the SSB index in the third SSB burst set period is 2, and the SSB index in the fourth SSB burst set period is 3. Thus, the terminal may determine that in the first SSB burst set, SSB#0 is received at the SSB candidate position of SSB#0, in the second SSB burst set, SSB#1 is received at the SSB candidate position of SSB#1, in the third SSB burst set, SSB#2 is received at the SSB candidate position of SSB#2, and in the fourth SSB burst set, SSB#3 is received at the SSB candidate position of SSB#3.

[0199] For example, in the embodiment shown in FIG3C , the network device may indicate that the SSB bitmap in the first SSB burst set period is 1000, the SSB bitmap in the second SSB burst set period is 0100, the SSB bitmap in the third SSB burst set period is 0010, and the SSB bitmap in the fourth SSB burst set period is 0001. Based on this, the terminal may determine that in the first SSB burst set, the SSB that the network device needs to send is SSB#0, and thus receives SSB#0 at the SSB candidate position of SSB#0; in the second SSB burst set, the SSB that the network device needs to send is SSB#1, and thus receives SSB#1 at the SSB candidate position of SSB#01; in the third SSB burst set, the SSB that the network device needs to send is SSB#2, and thus receives SSB#2 at the SSB candidate position of SSB#2; and in the fourth SSB burst set, the SSB that the network device needs to send is SSB#3, and thus receives SSB#3 at the SSB candidate position of SSB#3.

[0200] Of course, the network device may indicate which SSB is to be transmitted in the SSB burst set during the SSB cycle, which may be implemented independently of the embodiment shown in FIG3C . For example, the bitmap indicated by the network device is {1100,0011}, which may indicate that the SSBs transmitted in the first SSB burst set cycle are SSB#0 and SSB#1, and the SSBs transmitted in the second SSB burst set are SSB#2 and SSB#3.

[0201] In some embodiments, the time domain location condition of the SSB burst set includes at least one of the following:

[0202] The time domain interval of the SSB burst set is equal to the preset duration;

[0203] The time domain interval of the SSB burst set is less than the preset duration.

[0204] Of course, in some embodiments, the time domain interval of the SSB burst set may also be greater than the preset duration.

[0205] In some embodiments, since an SSB burst set may include one or more SSBs, when the SSBs in adjacent SSB burst sets are different, the network device needs to send multiple SSB burst sets to complete the sending of all SSBs.

[0206] For beam pairing, the terminal must match SSBs with beams. The terminal must receive each SSB (for example, through beam sweeping) to determine the most suitable beam for communication. This allows the terminal to use the most suitable beam to communicate with network devices, such as access network devices. Therefore, when the time domain interval between SSB bursts is too large, the terminal must attempt to receive SSBs over too many listening cycles to complete the reception of each SSB. This can lead to a long wait before beam pairing is completed, causing significant communication delays for the terminal.

[0207] Therefore, in an embodiment of the present disclosure, the first condition satisfied by the SSB transmission mode may include that the time domain interval of the SSB burst set is less than or equal to a preset duration, thereby avoiding that the time domain interval of the SSB burst set is too large, causing the terminal to wait for a long time to receive each SSB.

[0208] In some embodiments, the period during which the terminal monitors the SSB is determined from a set of candidate durations, for example, the set of candidate durations is {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. For example, if the terminal monitors the SSB for 20ms, the preset duration may be a first number of SSB monitoring periods, for example, the first number is denoted as P, and the preset duration is P×20ms.

[0209] For example, if P=1, it can ensure that the terminal can receive at least one SSB in each SSB monitoring cycle, which is conducive to ensuring that each SSB is received as soon as possible.

[0210] The method for determining P may be based on a predefined method (eg, protocol agreement) or indicated by a network device.

[0211] In some embodiments, the first indication information is also used to indicate the time domain position actually used to transmit the SSB burst set among the time domain positions of the candidate SSB burst set.

[0212] The candidate SSB burst set may refer to all candidate SSB burst sets in one SSB cycle. For example, in the embodiment shown in FIG3C , one SSB cycle includes four candidate SSB burst sets.

[0213] For example, for energy saving considerations, the network device may choose to send an SSB burst set at the time domain positions of some candidate SSB burst sets among the time domain positions of all candidate SSB burst sets, or choose not to send an SSB burst set at the time domain positions of some candidate SSB burst sets.

[0214] FIG3D is a schematic diagram showing a time domain interval of an SSB burst set according to an embodiment of the present disclosure.

[0215] As shown in Figure 3D, the time domain interval of the SSB burst set can be a candidate period of one SSB burst set (equal to the time domain interval of two candidate SSB burst sets), and the network device can adjust the time domain interval of the SSB burst set to a candidate period of two SSB burst sets, or further adjust it to a candidate period of three SSB burst sets.

[0216] The network device can indicate through a bitmap which time domain positions of the candidate SSB burst sets are actually used to transmit the SSB burst sets.

[0217] For example, for 8 candidate SSB burst sets, the time domain positions of the first 4 candidate SSB burst sets are actually used to transmit the SSB burst sets, then the bitmap sent by the network device to the terminal can be {11110000}, and the terminal can determine to receive SSB in the first 4 candidate SSB burst sets among the 8 candidate SSB burst sets, without having to receive SSB in the last 4 candidate SSB burst sets.

[0218] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0219] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0220] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0221] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0222] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .

[0223] In a first aspect, embodiments of the present disclosure provide a method for receiving information. Figure 4 is a schematic flow chart illustrating a method for receiving information according to an embodiment of the present disclosure. The method for receiving information illustrated in this embodiment can be executed by a terminal.

[0224] As shown in FIG4 , the information receiving method may include the following steps:

[0225] In step S401, a synchronous broadcast signal block (SSB) transmission mode is determined according to a predefined method, or the SSB transmission mode is determined according to first indication information of a network device, wherein the SSB transmission mode satisfies a first condition;

[0226] In step S402, the SSB sent by the network device is received according to the SSB transmission mode.

[0252] The second aspect and the optional implementation of the optional embodiment of the second aspect can be referred to the optional implementation in the embodiment shown in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0253] In some implementations, the Network Energy Saving (NES) initiative has been researched to reduce energy consumption in base stations and the network. During the research phase, NES technologies in the time, frequency, spatial, and power domains were thoroughly evaluated. During the standards phase, selected technologies in the time, spatial, and power domains were standardized.

[0254] In NR, the time domain locations of SSB / SIB1 transmission opportunities are semi-statically configured. The periodic transmission of common signals (e.g., SSB, SIB1, and the cell-common Physical Downlink Control Channel (PDCCH)) restricts the base station from using (deeper) sleep modes to save energy. Therefore, time domain technology achieves energy savings by limiting the transmission / reception of common signals and increasing the base station's sleep time.

[0255] Adaptation of SSB in time domain is a key candidate technology and will be subject to subsequent standardization research. In this technology, the SSB time pattern, for example, the SSB period, is adjusted. Base stations achieve network energy savings by extending the corresponding SSB period.

[0256] In the relevant mechanism, the time domain location of SSB transmission is determined based on predefined and / or network-side configuration. In NES scenarios, the base station needs to adjust the corresponding SSB transmission time domain location. However, there is currently no clear method for how the base station should adjust the corresponding SSB transmission time domain location.

[0257] In related technologies, SSB is sent periodically at a determined time-frequency resource location according to a period predefined by the protocol and / or configured by the network side.

[0258] About SSB: An SSB occupies four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain, including PSS, SSS and PBCH.

[0259] The NR system supports five SSB time domain transmission scenarios (cases), namely case A (SCS = 15KHz, working in frequency bands above 3GHz), case B (SCS = 30KHz, working in frequency bands above 3GHz), case C (SCS = 30KHz, TDD and working in frequency bands above 3GHz), case D (SCS = 120KHz, working in FR2 frequency band), and case E (SCS = 240KHz, working in FR2 frequency band). The time domain pattern of the case depends on factors such as the sub-carrier space (SCS) of the SSB, the operating frequency, the time division duplex (TDD) format, and the frequency division duplex (FDD) format. Different SSB cases correspond to the number of SSBs in an SSB burst and the time domain resource positions occupied in the burst. For example, the duration of the SSB burst is 5ms. For example, the transmission period of the SSB is 20ms. Furthermore, the base station can configure the SSB transmission period and time domain pattern through the relevant information carried in SIB1. The maximum transmission period of SSB is 160ms. For different cases, the SSB pattern can refer to the relevant technology, which will not be repeated in this disclosure.

[0260] During the cell search process, the terminal searches for the corresponding SSB based on the above-defined pattern with a period of 20ms. After the terminal resides on the cell, it can determine the SSB transmission period and the SSB actually transmitted in the SSB burst by receiving SIB1 or RRC indication signaling, and periodically receive the corresponding SSB based on the indication period and the SSB index actually transmitted in the SSB burst.

[0261] For base stations supporting NES, adjusting the timing of SSB transmissions through RRC signaling based on existing mechanisms requires refarming, which results in relatively long latency and is not suitable for dynamic adjustment scenarios. Adjusting the timing of SSB transmissions through SIB1 increases system information overhead and reduces network energy savings.

[0262] Based on the above analysis, this paper mainly designs a corresponding solution to achieve dynamic adjustment of SSB transmission timing position, thereby achieving network energy savings while avoiding impact on legacy users.

[0263] From the terminal side perspective:

[0264] A terminal supporting NES determines the time domain position of SSB transmission and receives the corresponding SSB, where the SSB meets the first condition.

[0265] In some embodiments, a terminal supporting NES determines the time domain position of SSB transmission based on a predefined or signaling indication method and receives the corresponding SSB, and the SSB satisfies the following first condition

[0266] The first condition is determined based on one or more of the following methods:

[0267] The corresponding SSB transmission period is equal to an integer multiple of N, where N is determined based on a predefined method or a signaling indication method. For example, N is equal to 5ms or 20ms.

[0268] The corresponding SSB transmission period can be less than or equal to 160ms, or greater than 160ms.

[0269] The SSB index transmitted within the corresponding SSB burst meets at least one of the following requirements:

[0270] For a specific SSB index / specific beam corresponding to the SSB, its transmission cycle interval is equal to M SSB burst transmission cycles, wherein, within M SSB burst transmission cycles, the base station transmits all SSBs corresponding to the beam. M is determined based on signaling instructions or predefined methods. For example, M is equal to the number of SSBs in the SSB burst.

[0271] The transmission interval corresponding to the SSB burst is equal to P SSB burst transmission cycles, where P is determined based on signaling instructions or a predefined method. Exemplarily, P is equal to 1, and exemplary, P is equal to 2.

[0272] The corresponding SSB burst transmission position is determined based on the transmission period. For example, the terminal receives indication signaling to determine the specific transmission position of the SSB burst, and the indication signaling is determined based on the bitmap method. For example, taking 8 SSB burst periods as an example, if the indication signaling is {1 1 1 1 0 0 0 0}, the terminal determines to receive the SSB burst at the first 4 SSB burst period positions.

[0273] From the base station side:

[0274] The base station supporting NES adjusts the time domain position of the SSB transmission based on the first condition and transmits the corresponding SSB.

[0275] In some embodiments, a base station supporting NES determines the time domain resources for SSB transmission based on the following first condition, and the SSB pattern can be defined based on the mechanism in the relevant technology.

[0276] The first condition is determined based on one or more of the following methods:

[0277] The corresponding SSB transmission period is equal to an integer multiple of N, where N is determined based on a predefined method or a signaling indication method. For example, N is equal to 5ms or 20ms.

[0278] The corresponding SSB transmission period can be less than or equal to 160ms, or greater than 160ms.

[0279] The SSB index transmitted within the corresponding SSB burst meets at least one of the following requirements:

[0280] For a specific SSB index / specific beam corresponding to an SSB, its transmission period interval is equal to M SSB burst transmission periods. Within M SSB burst transmission periods, the base station transmits all SSBs corresponding to the beam. M is determined based on signaling instructions or predefined methods. For example, M is equal to the number of SSBs in the SSB burst.

[0281] The transmission interval corresponding to the SSB burst is equal to P SSB burst transmission cycles, where P is determined based on signaling instructions or a predefined method. Exemplarily, P is equal to 1, and exemplary, P is equal to 2.

[0282] The corresponding SSB burst transmission position is determined based on the transmission period. For example, the terminal receives indication signaling to determine the specific transmission position of the SSB burst, and the indication signaling is determined based on the bitmap method. For example, taking 8 SSB burst periods as an example, if the indication signaling is {1 1 1 1 0 0 0 0}, the terminal determines to receive the SSB burst at the first 4 SSB burst period positions.

[0283] In the present disclosure, the base station flexibly adjusts the corresponding SSB transmission mode based on business needs and network energy saving requirements.

[0284] In some embodiments, the SSB transmission mode includes one or more of the following:

[0285] SSB transmission cycle;

[0286] SSB transmission pattern; the SSB transmission pattern can refer to the relevant technology and will not be described here.

[0287] The actual transmitted SSB index;

[0288] SSB transmission time domain resources;

[0289] SSB transmits frequency domain resources.

[0290] In one possible implementation scenario, when the SSB transmission mode is adjusted, the adjustment is transparent to the terminal. The terminal performs SSB reception based on predefined assumptions, such as a 20ms listening period or the SSB transmission mode indicated in system information / RRC signaling, such as SIB1. In this scenario, to avoid impacting the terminal's cell search, measurement, and other processes, the SSB transmission mode must meet the first condition.

[0291] Correspondingly, the terminal side expects the SSB transmission mode transmitted by the base station to meet the first condition based on its own cell search, measurement, time and frequency synchronization requirements.

[0292] Under the condition that the adjustment method is transparent to the terminal, the terminal can attempt to monitor the SSB based on the assumed transmission mode, e.g., a monitoring period of 20ms, and the SSB pattern determined based on the case in which the terminal is located; it can also attempt to monitor the SSB based on the SSB transmission mode determined by the existing signaling mechanism, e.g., SIB1 or RRC; it can also attempt to monitor the SSB based on the period defined by the first condition, pattern, actual transmitted SSB index, etc., and the present invention does not impose any restrictions on this.

[0293] Under the condition of SSB transmission mode adjustment, another possible implementation scenario is that the adjustment method is notified to the terminal by signaling. In the existing mechanism, the SSB transmission mode is notified to the terminal based on SIB1 or RRC signaling. In the NES scenario, the base station can choose to reuse the existing signaling mechanism, or introduce a new signaling mechanism to notify the terminal of the corresponding SSB transmission mode. Taking into account that the SSB transmission is cell-specific transmission, in order to reduce the impact of legacy terminals, an additional SSB transmission pattern can be introduced for the NES terminal, or the NES terminal and the legacy terminal can share the SSB transmission pattern. Similarly, in order to avoid affecting the terminal's cell search, measurement and other processes, and to avoid affecting the legacy terminal, the SSB transmission mode must meet the first condition.

[0294] Correspondingly, the terminal determines the transmission mode of the SSB based on the indication signaling and receives the corresponding SSB. The terminal side expects the SSB transmission mode to meet the first condition based on its own cell search, measurement, time-frequency synchronization and other requirements.

[0295] The following embodiments mainly focus on the specific content of the first condition above and describe the following scheme. The first condition includes at least one of the following: SSB transmission period, actual transmission SSB index, and SSB burst transmission interval.

[0296] Take the first condition including the SSB transmission period as an example:

[0297] The terminal determines, based on a predefined or signaling indication method, that the period of SSB transmission satisfies a first condition, and the condition includes but is not limited to: the transmission period of SSB satisfies the condition of being an integer multiple of the first time interval.

[0298] The first time interval is determined based on terminal capability reporting, predefinition or signaling indication.

[0299] Exemplarily, considering that the terminal attempts to search for SSB based on the 20ms assumption during the cell search phase, the first time interval is equal to 20ms.

[0300] Exemplarily, considering the existing mechanism, when the terminal is in the RRC connection state, if the corresponding SSB period is not configured, the terminal attempts to receive the SSB based on the assumption of 5ms, so the first time interval is equal to 5ms.

[0301] Exemplarily, considering that in the existing mechanism, the SSB configurable period is equal to one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, therefore, the first time interval is equal to one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}.

[0302] Based on the above assumptions, the transmission period of the SSB may belong to the existing optional configuration period set, ie, {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, or may not belong to the existing optional configuration period set, ie, 320ms;

[0303] From the perspective of the terminal, if the terminal expects the SSB transmission period to meet the first condition, the terminal may determine the transmission period of the monitored SSB in a predefined manner, e.g., 20ms or 5ms, or may determine the transmission period of the monitored SSB based on signaling notification. The signaling may be RRC, MAC CE, or DCI.

[0304] Application scenario 1 of the above solution: The base station flexibly adjusts the corresponding SSB transmission period based on the traffic volume and network energy saving requirements, and the SSB transmission period meets the first condition. The first period and the first period both meet the requirements of the first condition.

[0305] Application scenario 2 of the above solution: Based on the requirements of traffic volume and network energy saving, the base station introduces two sets of SSB transmission cycles, e.g., a default SSB cycle and an additional SSB transmission cycle. For example, the default SSB cycle is applied to legacy UEs and / or NES UEs, and the additional SSB transmission cycle is applied to NES users. For example, the additional SSB cycle is only applied to a first time range. The first time range is determined based on a signaling indication or a predefined method. Both the default SSB cycle and the additional SSB transmission cycle meet the first condition.

[0306] Take the first condition including the SSB burst transmission interval condition as an example:

[0307] The terminal determines, based on a predefined or signaling indication method, that the transmission interval between two adjacent SSB bursts meets a first condition, where the condition includes but is not limited to: the transmission interval between two adjacent SSB bursts is less than or equal to a first time interval.

[0308] The first time interval is determined based on a terminal capability report, predefined, or signaling indication;

[0309] Exemplarily, considering that the terminal attempts to search for SSB based on the assumption of 20 ms during the cell search phase, the terminal expects the transmission interval between two SSB bursts to be less than or equal to 20 ms.

[0310] For example, considering the existing mechanism, when the terminal is in the RRC connection state, if the corresponding SSB period is not configured, the terminal attempts to receive the SSB based on the assumption of 5ms. Therefore, the terminal expects the transmission interval between two SSB bursts to be less than or equal to 5ms.

[0311] For example, considering that in the existing mechanism, the SSB configurable period is equal to one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, the terminal expects the transmission interval between two SSB bursts to be less than or equal to one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}.

[0312] Based on the above assumptions, the transmission period of the SSB may belong to the existing optional configuration period set, ie, {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, or may not belong to the existing optional configuration period set, ie, 320ms;

[0313] For example, considering the energy saving requirements on the network side, the transmission interval between two adjacent SSB bursts can also meet the requirement of being greater than or equal to the second time interval. The definition of the second time interval is similar to that of the first time interval and will not be repeated here.

[0314] Application scenario 1 of the above solution: The base station determines the candidate time domain positions for SSB transmission based on the SSB transmission mode determined by the default SSB period, and selects some candidate time domain positions to transmit SSB based on the business volume and network energy saving requirements, or selects some candidate time domain positions not to transmit SSB.

[0315] It should be noted that if the transmission intervals between SSB bursts are the same, they can be defined based on the SSB transmission period.

[0316] From the perspective of the terminal, if the terminal expects two adjacent SSB transmission bursts to meet the first condition, the terminal can determine the time domain position of monitoring the SSB burst in a predefined manner, e.g., 20ms or 5ms, or determine the time domain position of monitoring the SSB based on signaling notification. The signaling can be RRC, MAC CE or DCI.

[0317] Taking the interval between SSB transmission bursts as an example based on pre-defined or DCI signaling indication, the specific implementation methods include:

[0318] The terminal determines the SSB transmission period, which is determined based on Example 1 (SSB transmission period) and will not be repeated here.

[0319] The terminal receives DCI indication signaling, indicating a transmission interval between SSB bursts, where the transmission interval is equal to P SSB transmission periods, where P is determined based on the signaling indication, and illustratively, P=2;

[0320] Alternatively, the terminal determines a transmission interval between SSB bursts based on a predefined manner, where the transmission interval is equal to P SSB transmission cycles, where P is determined based on a predefined manner, illustratively, P=2;

[0321] Exemplarily, the terminal may also determine the minimum or maximum transmission interval between SSB bursts based on a predefined or signaling indication method. The specific implementation method is similar to the above and will not be repeated here.

[0322] The terminal receives the indication signaling and determines the actual transmission position of the SSB burst. The indication signaling can use the association period as the granularity and indicate the actual transmission position of the SSB burst in a bitmap manner.

[0323] The association period is based on the granularity of N SSB transmission periods, where N is defined based on a predefined or signaling indication. For example, N=8;

[0324] The indication signaling indicates the actual transmission position of the SSB burst within the association period in a bitmap manner. Taking N=8 as an example, if the indication signaling indication bit is equal to {11110000}, the terminal determines to receive the corresponding SSB burst in the first 4 SSB burst periods.

[0325] Take the first condition including the SSB transmission index condition as an example:

[0326] The terminal determines, based on a predefined or signaling indication method, that the SSB index actually transmitted meets the first condition, including but not limited to: the SSB index actually transmitted within the SSB burst meets the following conditions:

[0327] Exemplarily, considering that for a single terminal, the terminal performs corresponding measurement, random access, etc. based on the optimal received SSB beam / index. Considering the requirement of the measurement interval or random access interval, the terminal expects that the transmission interval between the SSB / single SSB index corresponding to the single beam is less than or equal to the first time interval.

[0328] The first time interval is determined based on a predefined or signaling indication method. Exemplarily, the first time interval is equal to M SSB transmission cycles.

[0329] For example, from the network side perspective, the base station needs to serve multiple users in the cell, and the SSB receiving beams corresponding to different users may be different. Considering the needs of different users, the terminal expects that the base station can transmit all SSBs corresponding to the beam / index within the first time range.

[0330] The first time range is determined based on a predefined or signaling indication method. Exemplarily, the first time range is equal to N SSB transmission cycles. Exemplarily, N is equal to the number of SSBs contained in the SSB burst.

[0331] Application scenario 1 of the above solution: To meet the energy-saving requirements of the base station network, the number of SSBs transmitted in a single SSB burst is reduced as much as possible. At the same time, considering the needs of different users, all SSBs need to be transmitted in a beam sweeping manner. Taking the case where the number of SSBs contained in the SSB burst is equal to 4 as an example, the exemplary scenario is shown in Figure 3C.

[0332] The terminal determines the SSB index actually transmitted based on a predefined method or a signaling indication method.

[0333] Taking the predefined method as an example, the terminal determines the corresponding association period based on the predefined method. Exemplarily, the association period is equal to N SSB burst set periods, where N is equal to the number of SSBs designed to be transmitted in the SSB burst. Within the corresponding association period, the terminal determines to transmit SSB0 in the first SSB burst set period within the period, to transmit SSB1 in the second SSB burst set period, and so on.

[0334] Taking the signaling indication method as an example, the terminal indicates the association period based on a predefined or signaling indication method. For example, the association period is equal to N SSB burst set periods, and the SSB index designed for transmission on each SSB burst set period within the association period is indicated by a bitmap or index. Taking the association period equal to 4 SSB burst set periods and the indication signaling is {0, 1, 2, 3} as an example, the terminal determines that the SSB index designed for transmission within the 4 SSB periods are 0, 1, 2, and 3 respectively.

[0335] For example, taking the association period equal to 2 SSB burst set periods and the indication signaling as {1100,0011} as an example, the terminal determines that the SSB index transmitted in the first SSB burst set period is SSB 0 and SSB1, and the SSB index transmitted in the second SSB burst set period is SSB2 and SSB3.

[0336] The embodiments of the present invention focus on determining the first condition that the SSB transmission mode satisfies, based on the requirements of the terminal side, such as cell search, initial access, RRM measurement, and time-frequency synchronization, under the condition that the base station flexibly adjusts the SSB transmission mode based on the NES scenario. This helps achieve network energy conservation while meeting the needs of the terminal side.
