The CU-DU structure can separate the protocol layer of the network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0176] In some embodiments of NR (New Radio), the time-domain timing of the transmission of SSB (Synchronization Signal and PBCH block) / SIB1 (System Information Block Type 1) / cell common PDCCH (Physical Downlink Control Channel) / PRACH (Physical Random Access Channel) is semi-statically configured. The periodic transmission (SSB / SIB1 / cell common PDCCH) or periodic reception (PRACH) of the common signals limits the base station's use of (deeper) sleep modes to conserve energy. Therefore, time-domain techniques achieve energy conservation by limiting the transmission / reception of common signals, thereby increasing the base station's sleep time.

[0177] In some embodiments, the OD-SSB / SIB1 (on-demand-SSB / SIB1) technology in the time domain (sending synchronization information blocks SSB and system information blocks 1 on demand) is one of the important candidate technologies and will be standardized in Rel-19. In the OD-SSB technology, SSB / SIB1 is no longer sent periodically, but is sent according to the needs of terminals supporting NES functionality (NES UE).

[0178] For example, Figure 1B is a schematic diagram of OD-SSB / SIB1 transmission according to an embodiment of the present disclosure. As shown in Figure 1B, NES Cell#1 (energy-saving cell 1) (e.g., SCell (Secondary Cell)) stops periodically transmitting SSBs and is in NES (network energy-saving) state; Cell A (cell A) (e.g., PCell / spCell (Primary Cell / special Cell)) receives a first trigger signal, wherein the first trigger signal is a wake-up signal (WUS) sent by the UE to request OD-SSB from NES Cell#1; after receiving the first trigger signal, Cell A (PCell / spCell) transmits SSBs after a certain delay (entering non-NES (non-energy-saving) state), and after transmitting one or more SSB bursts, stops transmitting SSBs (returning to NES state).

[0179] In some embodiments, the transmission of OD-SSB can also be triggered by the base station. For example, NES Cell #1 stops periodically transmitting SSB and is in NES state; Cell A determines that NES Cell #1 should start transmitting OD-SSB based on certain conditions, and Cell A sends an OD-SSB transmission trigger signal for NES Cell #1; after receiving the OD-SSB transmission trigger signal from NES Cell #1, the UE sends feedback to Cell A that it has successfully received the OD-SSB transmission trigger signal from NES Cell #1; after receiving the feedback information from the UE, Cell A sends an SSB after a certain time delay (entering non-NES state), and after sending one or more SSB bursts, stops transmitting SSB (returning to NES state).

[0180] In some embodiments, in NES technology, the SSB in Cell A is sent periodically, while the SSB in NES Cell can be sent on demand. In addition, the transmission of SSB in NES Cell can include two cases: (1) There is no always-on SSB (always-on synchronization signal block SSB) in NES Cell; (2) There is always-on SSB in NES Cell that is sent periodically.

[0181] In some embodiments, the transmission period of always-on SSB is relatively long, and the UE can perform coarse synchronization based on always-on SSB. When the UE needs more SSBs for fine synchronization and / or RRM (Radio Resource Management) measurements, OD-SSB can be used.

[0182] In some embodiments, considering that at least one of OD-SSB and always-on SSB can be transmitted in the NES Cell, the UE needs to determine which of the following is the specific SSB transmission situation in the NES Cell:

[0183] Send OD-SSB and always-on SSB;

[0184] Send OD-SSB;

[0185] Send always-on SSB.

[0186] In some embodiments, this embodiment may be applicable to legacy UEs and NES-UEs. The network periodically transmits SSB bursts, with transmission periods including 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms. An SSB burst is transmitted in the first half (e.g., the first 5ms) or the second half (e.g., the last 5ms) of a system frame number (SFN). The maximum number of beams within an SSB burst is related to the frequency band of the carrier component (CC): 4 for bands below 3GHz, 8 for bands between 3GHz and 6GHz, and 64 for bands above 6GHz. For example, Figure 1C is a schematic diagram illustrating the distribution of an SSB burst set according to an embodiment of this disclosure. As shown in Figure 1C, an SSB burst contains 8 SSBs, transmitted in the first half (first 5ms), with an SSB period of 10ms.

[0187] Figure 1D is a schematic diagram illustrating SSB transmission according to an embodiment of this disclosure. As shown in Figure 1D, the SSB in the SSB burst is transmitted in different beam directions. After the UE accesses the cell, the UE has determined the optimal SSB beam. After the UE successfully receives and demodulates the SSB in the optimal SSB beam direction, it can obtain the time-frequency position of SearchSpace #0. The UE blindly detects the DCI (Downlink Control Information) transmitted by SIB1 in SearchSpace #0 to receive and demodulate SIB1.

[0188] In some embodiments, the base station periodically transmits SSBs according to its configuration. After the NES Cell supports OD-SSB technology, a new technology is needed to enable the UE to determine which of the following SSBs is being transmitted in the NES Cell:

[0189] Send OD-SSB and always-on SSB;

[0190] Send OD-SSB;

[0191] Send always-on SSB.

[0192] For example, for a UE that supports OD-SSB, determine whether the NES Cell includes always-on SSB and / or whether the NES Cell includes OD-SSB as follows:

[0193] Determine whether the cell includes always-on SSB based on the SSB configuration, and / or determine whether the cell includes OD-SSB;

[0194] Determine whether the Cell includes OD-SSB and / or whether the Cell includes always-on SSB based on the first, second, and third parameters.

[0195] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0196] Step S2101: The network device sends the first information to the terminal.

[0197] In some embodiments, the terminal receives first information sent by the network device.

[0198] In some embodiments, after a terminal accesses the network device, the network device can send the SSB configuration of the candidate cell corresponding to the terminal to the terminal, thereby enabling the terminal to determine which types of SSB configurations the corresponding candidate cell includes based on the first information. This facilitates the terminal's subsequent identification of the SSB configurations sent by the candidate cells and determination of which type of SSB configuration to use.

[0199] For example, in a cell handover scenario, after a terminal accesses cell A corresponding to a network device, the network device first identifies the SSB configurations of one or more neighboring cells B corresponding to cell A, determines the current SSB configuration type of each neighboring cell B, and generates first information. This first information is then sent to the terminal via cell A, enabling the terminal to determine the SSB configuration type of each neighboring cell B based on the first information. When the terminal hands over from cell A to a target neighboring cell B, it can determine the SSB information sent by the target neighboring cell B based on the target neighboring cell's SSB configuration type, allowing the terminal to synchronize with and access the target neighboring cell B.

[0200] Optionally, in some embodiments, the method further includes:

[0201] Based on the SSB configuration of the first cell, the network device determines whether the first cell includes at least one of the following: always-on SSB or OD-SSB.

[0202] Based on the judgment result, the network device generates the first information.

[0203] For example, during the process of a terminal accessing a cell, the network device determines the first cell corresponding to the terminal based on the terminal's current location and the cell distribution configured in the network device. This first cell can be a candidate cell for which the terminal will handover, or it can be another SCell (Secondary Cell) within the terminal's defined range. The network device identifies the SSB configuration of the first cell and determines whether it includes a first SSB. The first cell is a cell supporting NES functionality; that is, it can include an always-on SSB, which periodically sends SSBs to the radiation range without interruption. Simultaneously, the first cell can also include an OD-SSB, which sends SSBs to terminals within the radiation range according to the needs of terminals supporting NES functionality.

[0204] It should be noted that while the first cell supports OD-SSB, during network device configuration, based on the current network environment, cell A may have always-on SSB configured, cell B may have OD-SSB configured, and cell C may have both OD-SSB and always-on SSB configured. Therefore, during terminal access, after determining the first cell corresponding to the terminal, the network device identifies the SSB configuration of the first cell, determines whether the first cell includes the first SSB, obtains the corresponding determination result, and generates the first information based on the determination result.

[0205] For example, in this embodiment, the SSB configuration type included in the current SSB configuration of a cell indicates the SSB transmission mechanism currently used by the cell. For instance, if the SSB configuration in cell A is always-on SSB and OD-SSB is not present, it means that cell A currently uses the always-on SSB transmission mechanism. If the SSB configuration in cell C is both always-on SSB and OD-SSB, it means that cell C currently uses both always-on SSB and OD-SSB transmission mechanisms.

[0206] In some embodiments, the first SSB includes at least one of the following: always-on SSB and OD-SSB. Always-on SSB is a continuously transmitted SSB that the network periodically transmits regardless of whether a terminal requests synchronization. Always-on SSB ensures that the UE can detect the cell and synchronize at any time, which is beneficial for ensuring cell discoverability and reducing UE search time. OD-SSB is an on-demand triggered SSB that is transmitted only when the UE requests synchronization, or under specific conditions according to network configuration. OD-SSB can reduce unnecessary signal transmission, thereby reducing network energy consumption, especially in areas with few users or low traffic. This mechanism requires the UE to explicitly request a synchronization signal, or the network to transmit the SSB based on certain triggering conditions (such as beam failure recovery), which may increase UE access latency, but helps save energy and improve network efficiency.

[0207] For example, always-on SSB and OD-SSB are two different SSB transmission strategies used in communication systems to optimize cell synchronization and energy consumption. Always-on SSB focuses on providing continuous synchronization signals to improve user experience, while OD-SSB focuses on energy saving and reducing unnecessary signal transmission. Network operators can choose the appropriate SSB transmission mechanism based on specific network conditions and service requirements. In this embodiment, the first SSB may include always-on SSB and / or OD-SSB. For example, the first SSB may be always-on SSB, the first SSB may be OD-SSB, or the first SSB may be both always-on SSB and OD-SSB.

[0208] In some embodiments, the network device indicates to the terminal, via first information, the first SSB type included in the first cell. This first information can be directly indicated to the terminal through SSB configuration; alternatively, it can also be indicated to the terminal via parameter values.

[0209] Optionally, in some embodiments, step S2101 above may include at least one of the following:

[0210] The SSB configuration includes a first SSB configuration and a second SSB configuration. The first cell is determined to include always-on SSB and OD-SSB. The first SSB configuration is for always-on SSB, and the second SSB configuration is for OD-SSB. The first information includes the first SSB configuration and the second SSB configuration.

[0211] The SSB configuration includes the first SSB configuration, and the first information does not include the second SSB configuration. It is determined that the first cell includes always-on SSB, the first cell does not include OD-SSB, and the first information includes the first SSB configuration.

[0212] The SSB configuration includes a second SSB configuration, and the first information does not include the first SSB configuration. It is determined that the first cell includes OD-SSB, the first cell does not include always-on SSB, the second SSB configuration is a configuration for OD-SSB, and the first information includes a third SSB configuration.

[0213] For example, the first SSB is configured for always-on SSB, and the second SSB is configured for OD-SSB. When the SSB configuration corresponding to the first cell includes the first SSB configuration, the first cell is determined to include always-on SSB; when the SSB configuration corresponding to the first cell includes the second SSB configuration, the first cell is determined to include OD-SSB. When the SSB configuration corresponding to the first cell includes both the first and second SSB configurations, the first cell is determined to include both always-on SSB and OD-SSB.

[0214] Optionally, in some embodiments, a first SSB configuration can be set for always-on SSB configuration, and a second SSB configuration can be set for OD-SSB configuration. The second SSB configuration cannot exist independently. The second SSB configuration can only be used for OD-SSB configuration if the first SSB configuration is included in the SSB configuration corresponding to the first cell. A third SSB configuration is also used for OD-SSB configuration, but it can exist independently and be used solely for OD-SSB configuration.

[0215] For example, if the SSB configuration corresponding to the first cell includes the first SSB configuration and the second SSB configuration, then it is determined that the first cell includes both always-on SSB and OD-SSB.

[0216] If the SSB configuration corresponding to the first cell includes the first SSB configuration, and the SSB configuration does not include the second SSB configuration, then it is determined that the first cell includes always-on SSB and does not include OD-SSB.

[0217] If the SSB configuration corresponding to the first cell includes the third SSB configuration, and the SSB configuration does not include the first SSB configuration, then it is determined that the first cell includes OD-SSB and does not include always-on SSB.

[0218] In some embodiments, the second SSB configuration and the third SSB configuration include at least one of the following:

[0219] Subcarrier spacing (SCS) of OD-SSB;

[0220] The cycle of OD-SSB;

[0221] The subframe where the OD-SSB is located;

[0222] The half-frame containing the OD-SSB;

[0223] The symbols containing each SSB in the OD-SSB group;

[0224] The first frequency domain position of the OD-SSB is used to indicate the frequency domain position of the OD-SSB.

[0225] The number of OD-SSB groups that have been transmitted since OD-SSB transmission began;

[0226] The duration of OD-SSB after it begins transmission;

[0227] The physical cell identifier of the cell where the OD-SSB is located;

[0228] Downlink transmit power of OD-SSB.

[0229] In some embodiments, both the second SSB configuration and the third SSB configuration are configurations for OD-SSB. The second SSB configuration must exist together with the first SSB configuration and cannot exist independently. That is, given that the SSB configuration corresponding to the first cell includes the first SSB configuration, it is determined whether the second SSB configuration is included in that SSB configuration, thereby determining whether the first cell includes OD-SSB. The third SSB configuration can exist independently and is used to directly indicate whether the first cell includes OD-SSB. The parameters included in the second and third SSB configurations can be the same or different. The second and third SSB configurations include at least one of the following parameters:

[0230] The SCS of OD-SSB can be configured using the always-on SSB SCS configuration method;

[0231] The OD-SSB cycle can be configured using the always-on SSB cycle configuration method;

[0232] The subframe containing the OD-SSB, for example, can be configured using the same method as the frame containing the always-on SSB. The configurable offset of the OD-SSB relative to the always-on SSB is the offset between the first SSB burst of the OD-SSB and the first burst of the always-on SSB, in frames.

[0233] The half-frame where OD-SSB is located: The always-on SSB half-frame configuration method can be used;

[0234] The symbol where the SSB is located in the OD-SSB burst: The symbol configuration method for the SSB in always-on SSB can be used;

[0235] The frequency domain location information of the OD-SSB includes at least one of the following: the frequency domain configuration method of the always-on SSB can be used; the offset value relative to the frequency domain location of the always-on SSB can be configured. For example, the offset between the OD-SSB's GCSN (Global Synchronization Channel Number) and the always-on SSB's GCSN can be configured;

[0236] After OD-SSB transmission begins, the number of OD-SSB bursts transmitted is greater than or equal to 1 burst.

[0237] The duration of OD-SSB after it starts transmitting: in units of slot / subframe / frame;

[0238] The physical cell ID of the cell where the OD-SSB is located;

[0239] Downlink transmit power of OD-SSB: The downlink transmit power configuration method of always-on SSB can be adopted.

[0240] For example, the network device identifies the SSB configuration of the first cell, determines whether the first cell includes a first SSB, and generates first information based on the determination result. The first information includes at least one of the following: first SSB configuration, second SSB configuration, and third SSB configuration.

[0241] For example, the first information includes the first SSB configuration and the second SSB configuration, indicating that the first cell includes always-on SSB and OD-SSB;

[0242] The first information includes a first SSB configuration, but does not include a second SSB configuration, indicating that the first cell includes an always-on SSB, but the first cell does not include the OD-SSB;

[0243] The first information includes the third SSB configuration, but does not include the first SSB configuration, indicating that the first cell includes OD-SSB and does not include always-on SSB.

[0244] Optionally, in this embodiment, the SSB configuration of the first cell can also be indicated to the terminal according to the parameters.

[0245] For example, the first information includes at least one of the following: the first parameter, the second parameter, and the third parameter.

[0246] The first parameter is used by the terminal to determine whether the first cell includes an OD-SSB.

[0247] The second parameter is used by the terminal to determine whether the first cell includes always-on SSB.

[0248] The third parameter is used by the terminal to determine whether the first cell includes at least one of the following: OD-SSB or always-on SSB.

[0249] Optionally, in some embodiments, the above step "generating first information based on the determination result" includes at least one of the following:

[0250] The network device determines that the first cell includes an OD-SSB, generates first information, which includes a first parameter, and the first parameter takes a first value.

[0251] The network device determines that the first cell does not include OD-SSB, generates first information, which includes first parameter, and the value of the first parameter is not the first value;

[0252] The network device determines that the first cell includes an OD-SSB and generates first information, which does not include the first parameter.

[0253] The network device determines that the first cell does not include OD-SSB, and generates first information, which does not include the first parameter.

[0254] For example, in this embodiment, multiple methods can be used to indicate whether the first cell includes an OD-SSB based on the first parameter in the first information. For instance: if the first parameter takes a first value, it indicates that the first cell includes an OD-SSB; if the first parameter is not a first value, it indicates that the first cell does not include an OD-SSB; if the first parameter is not configured in the first information, it indicates that the first cell includes an OD-SSB; if the first parameter is not configured in the first information, it indicates that the first cell does not include an OD-SSB. In this embodiment, the specific value of the first value is not limited and can be set based on the current network configuration. For example, the first value can be set to 1.

[0255] Optionally, in some embodiments, the above step "generating first information based on the determination result" includes at least one of the following:

[0256] The network device determines that the first cell includes an always-on SSB, generates first information, the first information includes a second parameter, and the second parameter takes a second value;

[0257] The network device determines that the first cell does not include an always-on SSB, generates first information, which includes a second parameter, and the value of the second parameter is not a second value;

[0258] The network device determines that the first cell includes an always-on SSB and generates first information, which does not include the second parameter.

[0259] The network device determines that the first cell does not include always-on SSB, generates first information, and the first information does not include the second parameter.

[0260] For example, in this embodiment, the second parameter in the first information indicates whether the first cell includes always-on SSB. For instance, if the second parameter takes the second value, it indicates that the first cell includes always-on SSB; if the second parameter is not the second value, it indicates that the first cell does not include always-on SSB; if the second parameter is not configured in the first information, it indicates that the first cell includes always-on SSB; if the second parameter is not configured in the first information, it indicates that the first cell does not include always-on SSB. In this embodiment, the specific value of the second value is not limited and can be set based on the current network configuration; for example, the second value can be set to 0.

[0261] Optionally, in some embodiments, the above step "generating first information based on the determination result" includes at least one of the following:

[0262] The network device determines that the first cell includes always-on SSB and OD-SSB, generates first information, which includes a third parameter, and the third parameter takes a third value.

[0263] The network device determines that the first cell includes an always-on SSB, generates first information, and the first information includes a third parameter, the third parameter being a fourth value;

[0264] The network device determines that the first cell includes OD-SSB, generates first information, which includes a third parameter, and the third parameter takes the fifth value.

[0265] The network device determines that the first cell includes always-on SSB and OD-SSB, and generates first information, which does not include the third parameter;

[0266] The network device determines that the first cell includes an always-on SSB and generates first information, which does not include the third parameter.

[0267] The network device determines that the first cell includes OD-SSB and generates first information, which does not include the third parameter.

[0268] For example, in this embodiment, the second parameter in the first information indicates whether the first cell includes always-on SSB and OD-SSB. For instance, the third parameter taking a third value indicates that the first cell includes always-on SSB and OD-SSB; the third parameter taking a fourth value indicates that the first cell includes always-on SSB; the third parameter taking a fifth value indicates that the first cell includes OD-SSB; the first information not including the third parameter indicates that the first cell includes always-on SSB and OD-SSB; the first information not including the third parameter indicates that the first cell includes always-on SSB; the first information not including the third parameter indicates that the first cell includes OD-SSB. In this embodiment, the specific values ​​of the third, fourth, and fifth values ​​are not limited and can be set based on the current network configuration. For example, the third value can be set to 0, the fourth value to 1, and the fifth value to 10.

[0269] In some embodiments, after determining the SSB configuration of the first cell, determining whether the first cell includes the first SSB, generating first information, the network device sends the first information to the terminal.

[0270] In some embodiments, the first information is used to indicate the first SSB included in the first cell.

[0271] In some embodiments, the name of the first information is not limited, and it may be, for example, “SSB type information”, “SSB indication information”, or “SSB configuration information”.

[0272] In step S2102, the terminal determines, based on the first information, whether the first cell of the network device includes at least one of the following: always-on SSB, OD-SSB.

[0273] For example, in this embodiment, the first information may be an SSB configuration. The terminal determines whether the first cell includes a first SSB based on whether the first information includes a first SSB configuration and a second SSB configuration. The definitions of the first SSB configuration and the second SSB configuration are the same as in the above embodiments and will not be repeated here.

[0274] For example, the terminal can determine whether the first cell includes the first SSB in any of the following ways:

[0275] The first information includes the first SSB configuration and the second SSB configuration, and determines that the first cell includes always-on SSB and OD-SSB;

[0276] The first information includes the first SSB configuration, but does not include the second SSB configuration, thus determining that the first cell includes always-on SSB and does not include OD-SSB;

[0277] The first information includes the second SSB configuration, and the first information does not include the first SSB configuration. It is determined that the first cell includes OD-SSB, the first cell does not include always-on SSB, and the second SSB configuration is a configuration for OD-SSB.

[0278] In some embodiments, the terminal can determine whether the first cell includes the first SSB based on whether the first information includes the first parameter, the second parameter, and the third parameter, and the values ​​of the first parameter, the second parameter, and the third parameter. The definitions of the first parameter, the second parameter, and the third parameter are the same as in the embodiments described above, and will not be repeated here.

[0279] For example, the terminal can determine whether the first cell includes the first SSB in any of the following ways:

[0280] (1) The first information includes the first parameter, the first parameter takes the first value, and the first cell is determined to include OD-SSB;

[0281] The first information includes the first parameter. If the value of the first parameter is not the first value, it is determined that the first cell does not include OD-SSB.

[0282] The first information does not include the first parameter, and it is determined that the first cell includes OD-SSB;

[0283] The first information does not include the first parameter, and the first cell does not include OD-SSB.

[0284] (2) The first information includes the second parameter, and the first parameter takes the value of the second value, thus determining that the first cell includes always-on SSB;

[0285] The first information includes the second parameter. If the value of the second parameter is not the second value, it is determined that the first cell does not include always-on SSB.

[0286] The first information does not include the second parameter, and it is determined that the first cell includes always-on SSB;

[0287] The first information does not include the second parameter, and the first cell does not include always-on SSB.

[0288] (3) The first information includes the third parameter, the third parameter takes the third value, and the first cell is determined to include always-on SSB and OD-SSB;

[0289] The first information includes the third parameter, which takes the value of the fourth value, and determines that the first cell includes always-on SSB;

[0314] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2102. For example, step S2101 may be implemented as a separate embodiment, and step S2102 may be implemented as a separate embodiment, but are not limited thereto.

[0315] In some embodiments, steps S2101 and S2102 may be performed in an alternate order or simultaneously.

[0316] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0318] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method, which includes:

[0319] In step S2201, the network device sends the first information to the terminal through the second cell.

[0320] In some embodiments, the second cell is the cell currently accessed by the terminal, and the first cell is a neighboring cell of the second cell. The network device corresponding to the second cell can be the same as or different from the network device corresponding to the first cell. For example, in a cell handover scenario, during the process of the terminal switching from the second cell to the first cell, the first cell is a candidate cell to which the terminal will switch. At this time, if the network device corresponding to the first cell is the same as the network device corresponding to the second cell, the terminal is currently performing an intra-cell handover; if the network device corresponding to the first cell is different from the network device corresponding to the second cell, the terminal is currently performing an out-of-cell handover. The definition of the first information is the same as in the above embodiments and will not be repeated here. The network device sends the first information to the terminal through the second cell, enabling the terminal to determine the SSB configuration of the first cell pair and assisting the terminal in performing cell handover. For example, if the network device A of the first cell is different from the network device B of the second cell, network device B can interact with network device A to request the SSB configuration of the first cell, generate the first information, and send the first information to the terminal through the second cell.

[0321] It should be noted that this embodiment can also be applied to other communication scenarios. For example, the network device can send the SSB configuration of the first cell to the terminal. The terminal performs measurements based on the SSB configuration information and reports the measurement results to the network device, thereby helping the network device make scheduling and handover decisions. The terminal can also use the SSB configuration information to perform channel estimation, which facilitates the network device in subsequent data transmission and signal scheduling. By sending the SSB configuration information, the network device can optimize network resource allocation and cell management, etc.

[0322] For example, in a cell handover scenario, after a terminal accesses cell A corresponding to a network device, the network device first identifies the SSB configurations of one or more neighboring cells B corresponding to cell A, determines the current SSB configuration type of each neighboring cell B, and generates first information. This first information is then sent to the terminal via cell A, enabling the terminal to determine the SSB configuration type of each neighboring cell B based on the first information. When the terminal hands over from cell A to a target neighboring cell B, it can determine the SSB information sent by the target neighboring cell B based on the target neighboring cell's SSB configuration type, allowing the terminal to synchronize with and access the target neighboring cell B.

[0323] The optional implementation of step S2201 can be found in the optional implementation of step S2101 in Figure 2A, as well as other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0324] In step S2202, the terminal determines, based on the first information, whether the first cell includes at least one of the following: always-on SSB, OD-SSB.

[0325] The optional implementation of step S2202 can be found in the optional implementation of step S2102 in Figure 2A, as well as other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0326] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2202. For example, step S2201 may be implemented as a separate embodiment, and step S2202 may be implemented as a separate embodiment, but are not limited thereto.

[0327] In some embodiments, steps S2201 and S2202 may be performed in an alternate order or simultaneously.

[0328] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0329] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0353] Figure 3B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, the present disclosure relates to a communication method, which includes:

[0354] In step S3201, the network device sends first information to the terminal. The first information includes at least one of the following: a first parameter, a second parameter, and a third parameter.

[0355] In step S3202, the terminal determines, based on the first information, whether the first cell of the network device includes at least one of the following: always-on SSB, OD-SSB.

[0378] Figure 4A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4A, the embodiments of the present disclosure relate to a communication method, which includes:

[0379] Step S4101: The network device sends the SSB configuration to the terminal.

[0380] In step S4102, the terminal determines whether the Cell includes always-on SSB and whether it includes OD-SSB based on the SSB configuration.

[0381] For example, the SSB configuration contains both a first SSB configuration and a second SSB configuration, which determines that the Cell includes both always-on SSB and OD-SSB.

[0382] The SSB configuration includes the first SSB configuration but does not include the second SSB configuration, and it is determined that the Cell includes always-on SSB but does not include OD-SSB.

[0383] The SSB configuration includes a third SSB configuration but not a first SSB configuration, ensuring that the Cell contains an OD-SSB but not an always-on SSB.

[0384] In some embodiments, the first SSB is configured for always-on SSB, and the second and third SSBs are configured for OD-SSB.

[0385] In some embodiments, the second SSB configuration and the third SSB configuration include at least one of the following:

[0386] SCS of OD-SSB;

[0387] The cycle of OD-SSB;

[0388] The subframe where the OD-SSB is located;

[0389] The half-frame containing the OD-SSB;

[0390] The symbol containing the SSB in an OD-SSB burst;

[0391] The frequency domain location information of the OD-SSB includes at least one of the following: offset relative to the frequency domain location of the always-on SSB; the frequency domain location of the OD-SSB, wherein the first frequency domain location is used to indicate the frequency domain location of the OD-SSB.

[0392] The number of OD-SSB bursts transmitted after OD-SSB transmission begins;

[0393] The duration of OD-SSB after it begins transmission;

[0394] The physical cell ID of the cell where the OD-SSB is located;

[0395] Downlink transmit power of OD-SSB;

[0396] In some embodiments, the second SSB configuration and the third SSB configuration may contain the same or different parameters.

[0397] For example, the first SSB configuration may include at least one of the following:

[0398] The SCS of always-on SSB, such as the SSB Subcarrier Spacing configuration, can take the following values: 15KHz / 30KHz / 120KHz / 240KHz / 480KHz / 960KHz.

[0399] The always-on SSB period, for example, the period value configured for SSB Periodicity, can be 5ms / 10ms / 20ms / 40ms / 80ms / 160ms.

[0400] The subframe in which the always-on SSB is located, such as at least one of SFN-Offset (System Frame Number Offset), Integer Subframe Offset, or SFN-SSB-Offset (System Frame Number Synchronization Block Offset).

[0401] SFN-Offset indicates the offset between the Cell and the SFN of the serving cell, in units of SF (System Frame), and can take values ​​of: 0, 1, 2, ..., 1023.

[0402] The Integer Subframe Offset indicates the offset between the Cell and the Subframe boundary of the serving cell, in units of Subframes, and can take values ​​of 0, 1, 2, ..., 9.

[0403] By combining the SFN-Offset, Integer Subframe Offset, and the SFN boundary of the serving cell, the SFN boundary of the cell can be determined.

[0404] Figure 4B is a schematic diagram of SFN numbering according to an embodiment of the present disclosure. As shown in Figure 4B, for example: SFN-Offset is 3, indicating that the offset between the Cell and the SFN number of the serving cell is 3, and Integer Subframe Offset is 3, indicating that the offset between the Cell and the subframe number of the serving cell is 3.

[0405] SFN-SSB-Offset indicates the offset of the frame in the cell where the always-on SSB is transmitted relative to the period of the always-on SSB, in units of SF (system frame), and can take values ​​of 0, 1, 2, 3, ..., 15.

[0406] By combining SSB-Periodicity and SFN-SSB-Offset, the frame in which the always-on SSB is located within the cell can be determined.

[0407] For example, if SSB-Periodicity is 160ms and SFN-SSB-Offset is 10, then the always-on SSB will be in the 11th frame out of every 16 frames, with the first frame being the first frame out of every 16 frames.

[0408] The always-on SSB is located in the half-frame, such as halfFrameIndex (half-frame index). For example, a value of 0 represents the first half-frame, and a value of 1 represents the second half-frame.

[0409] The symbol containing the SSB in an always-on SSB burst, such as SSB-PositionsInBurst.

[0410] According to the SSB Pattern agreed upon in the protocol, the symbol where each SSB Index is located can be determined; according to ssb-PositionsInBurst, the actual SSB Index to be sent can be determined; combined with the symbol where each SSB Index is located as determined according to the protocol, the symbol where the actual SSB Index is sent can be determined.

[0411] The frequency domain location information of always-on SSB. For example, absoluteFrequency SSB, with a value of ARFCN-ValueNR (Absolute Radio Frequency Channel Number), determines the starting frequency domain location of always-on SSB according to the protocol and ARFCN-ValueNR.

[0412] Optionally, the frequency domain location of the always-on SSB may not be on the frequency corresponding to the GSCN (Global Sync Channel Number).

[0413] The physical cell ID of the cell where the always-on SSB is located.

[0414] Downlink transmit power of always-on SSB, such as SS-PBCH-Block Power (Synchronization Signal PBCH Block Power).

[0415] In some embodiments, the second SSB configuration and the third SSB configuration include at least one of the following:

[0416] The SCS of OD-SSB can be configured using the always-on SSB SCS configuration method;

[0417] The OD-SSB cycle can be configured using the always-on SSB cycle configuration method;

[0418] The subframe containing the OD-SSB, for example, can be configured using the same method as the frame containing the always-on SSB. The offset of the OD-SSB relative to the always-on SSB can be configured: the offset between the first SSB burst of the OD-SSB and the first burst of the always-on SSB, in units of frame / subframe / slot;

[0419] The half-frame where OD-SSB is located: The always-on SSB half-frame configuration method can be used;

[0420] The symbol where the SSB is located in the OD-SSB burst: The symbol configuration method for the SSB in always-on SSB can be used;

[0421] The frequency domain location information of the OD-SSB includes at least one of the following: the frequency domain configuration method of the always-on SSB can be used; the offset value relative to the frequency domain location of the always-on SSB can be configured. For example, the offset between the OD-SSB's GCSN (Global Synchronization Channel Number) and the always-on SSB's GCSN can be configured;

[0422] After OD-SSB transmission begins, the number of OD-SSB bursts transmitted is greater than or equal to 1 burst.

[0423] The duration of OD-SSB after it starts transmitting: in units of slot / subframe / frame;

[0424] The physical cell ID of the cell where the OD-SSB is located;

[0425] Downlink transmit power of OD-SSB: The downlink transmit power configuration method of always-on SSB can be adopted.

[0426] In some embodiments, the parameters included in the second SSB configuration and the third SSB configuration may be the same or different.

[0427] In some embodiments, a first SSB configuration and a second SSB configuration are configured simultaneously. When the first parameter of the second SSB configuration is the same as that of the first SSB configuration, the value of the first parameter of the first SSB configuration can be reused. The first parameter may not be configured in the second SSB configuration.

[0428] For example, the first parameter may include at least one of the following:

[0429] SSB's SCS;

[0430] The SSB cycle;

[0431] The subframe where SSB is located;

[0432] The half-frame in which SSB is located;

[0433] The symbol containing the SSB in the SSB burst;

[0434] The frequency domain location of the SSB;

[0435] The physical cell ID of the cell where the SSB is located;

[0436] SSB downlink transmit power;

[0437] In some embodiments, when only a third SSB configuration is available, the first parameter in the third SSB configuration cannot reuse the first SSB configuration because there is no first SSB configuration.

[0438] In some embodiments, Cell is a secondary cell SCell; optionally, Cell supports OD-SSB.

[0439] In some embodiments, the serving cell is a PCell, a SpCell, or a PSCell (Primary Secondary Cell); wherein, a sPCell can be considered as the union of PCell and PSCell.

[0440] In some embodiments, the OD-SSB is configured with multiple periods P, and one of these periods P1 can be agreed upon / configured as the default period. Optionally, the value of N1 can be different for different uses of the OD-SSB. These uses include, but are not limited to: RRM (Radio Resource Management), RLM (Radio Link Monitoring), BFR (Beam Failure Recovery) and BM (Beam Management), Scell ​​activation, synchronization, and mobility management.

[0441] In some embodiments, OD-SSB takes effect immediately after configuration, and OD-SSB uses the default cycle.

[0442] In some embodiments, when a network device instructs OD-SSB transmission, if the OD-SSB period is not specified, the OD-SSB transmission uses a default period. The instruction may include a MAC CE / DCI instruction. Optionally, the DCI is a Group Common DCI.

[0443] In some embodiments, during transmission, the OD-SSB can indicate a new OD-SSB period via RRC / MAC CE / DCI, and the new OD-SSB period can be used after a certain time delay.

[0444] In some embodiments, the number N of OD-SSB bursts sent by the OD-SSB is configured with multiple candidate values. A candidate value N1 can be agreed upon / configured as the default number. Optionally, the value of N1 can be different for different uses of the OD-SSB. These uses include, but are not limited to: RRM, RLM, BFR and BM, scell activation, synchronization, and mobility management.

[0445] In some embodiments, OD-SSB takes effect immediately after configuration, and OD-SSB uses the default number of OD-SSB bursts N1;

[0446] In some embodiments, when a network device indicates OD-SSB transmission, if the number of OD-SSB bursts is not indicated, the OD-SSB transmission uses the default number of OD-SSB bursts N1. The indication may include a MAC CE / DCI indication. Optionally, the DCI is a GroupCommon DCI.

[0447] In some embodiments, during transmission, the new number of OD-SSB bursts N2 can be indicated by RRC / MAC CE / DCI, and the new number of OD-SSB bursts N2 can be used after a certain time delay.

[0448] In some embodiments, the duration T of the OD-SSB transmitted by the OD-SSB is configured with multiple candidate values. A candidate value T1 can be agreed upon / configured as the default number. Optionally, the value of T1 can be different for different uses of the OD-SSB. These uses include, but are not limited to: RRM, RLM, BFR and BM, scell activation, synchronization, and mobility management.

[0449] In some embodiments, OD-SSB takes effect immediately after configuration, and OD-SSB uses the default OD-SSB duration T1;

[0450] In some embodiments, when a network device indicates OD-SSB transmission, if the OD-SSB duration is not specified, the OD-SSB transmission uses the default OD-SSB duration T1. The indication may include a MAC CE / DCI indication. Optionally, the DCI is a GroupCommon DCI.

[0451] In some embodiments, during transmission, the OD-SSB can indicate a new OD-SSB duration T2 via RRC / MAC CE / DCI, and use the new OD-SSB duration T2 after a certain delay.

[0452] In some embodiments, other parameters of OD-SSB are configured with multiple candidate values, and the values ​​used for OD-SSB transmission can be determined using the methods described above.

[0453] In some embodiments, when both OD-SSB and always-on SSB exist, and the time-frequency overlap of OD-SSB and always-on SSB includes at least one of the following:

[0454] When the SSB Index of time-frequency overlapping OD-SSB and always-on SSB is the same, the time-frequency overlapping SSB is measured using either always-on SSB or OD-SSB; optionally, the network side only sends either always-on SSB or OD-SSB in the time-frequency overlapping SSB; the sending network side can send either always-on SSB or OD-SSB according to the protocol agreement / configuration.

[0455] When the SSB Indexes of time-frequency overlap OD-SSB and always-on SSB are different, the SSB of time-frequency overlap shall be measured using at least one of always-on SSB and OD-SSB.

[0456] In some embodiments, when both OD-SSB and always-on SSB exist, and the time domains of OD-SSB and always-on SSB overlap but their frequency domains do not overlap, at least one of the following applies.

[0457] When the SSB Indexes of OD-SSB and Always-on SSB that overlap in the time domain but do not overlap in the frequency domain are the same, the SSBs that overlap in the time domain but do not overlap in the frequency domain shall be measured using at least one of Always-on SSB and OD-SSB; optionally, the network side shall only send one of Always-on SSB or OD-SSB for SSBs that overlap in the time domain but do not overlap in the frequency domain; the sending network side may send Always-on SSB or OD-SSB according to the protocol agreement / configuration.

[0460] Figure 4C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4C, the embodiments of the present disclosure relate to a communication method, which includes:

[0461] In step S4201, the network device sends at least one of the first parameter, the second parameter, and the third parameter to the terminal.

[0462] In step S4202, the terminal determines whether the Cell includes an OD-SSB and whether it includes an always-on SSB based on at least one of the first parameter, the second parameter, and the third parameter.

[0463] In some embodiments, the terminal determines whether the Cell contains an OD-SSB based on a first parameter, including at least one of the following:

[0464] The first parameter takes the value of A, and the Cell contains OD-SSB;

[0465] The first parameter takes the value of B, and the Cell does not contain OD-SSB;

[0466] The first parameter is not configured, and the Cell contains OD-SSB.

[0467] The first parameter is not configured, and the Cell does not contain OD-SSB.

[0468] In some embodiments, the terminal determines whether the Cell contains an always-on SSB based on a second parameter, including at least one of the following:

[0469] The second parameter takes the first value, and Cell contains always-on SSB;

[0470] The second parameter takes the second value, and Cell does not contain always-on SSB;

[0471] The second parameter is not configured; Cell contains always-on SSB.

[0472] The second parameter is not configured, and Cell does not contain always-on SSB;

[0473] In some embodiments, the terminal determines whether the Cell contains an OD-SSB and whether it contains an always-on SSB based on a third parameter, including at least one of the following:

[0474] The third parameter takes the third value, and Cell includes always-on SSB and OD-SSB;

[0475] The third parameter takes the fourth value, and Cell contains always-on SSB;

[0476] The third parameter takes the fifth value, and the Cell contains OD-SSB;

[0477] The third parameter is not configured; Cell includes always-on SSB and OD-SSB.

[0478] The third parameter is not configured; Cell contains always-on SSB.

[0479] The third parameter is not configured, and the Cell contains OD-SSB.

[0480] In some embodiments, the terminal determines whether the Cell contains an OD-SSB and whether it contains an always-on SSB based on a first parameter and a second parameter. After determining that the Cell supports OD-SSB, the terminal can determine whether the Cell contains an OD-SSB based on the first parameter.

[0481] For example, a value of 1 for the first parameter indicates that the cell contains an OD-SSB, while a value of 0 or no configuration of the first parameter indicates that the cell does not contain an OD-SSB.

[0482] For example, a first parameter value of 0 indicates that the cell does not contain an OD-SSB, while a first parameter value of 1 or no first parameter configuration indicates that the cell contains an OD-SSB.

[0483] The terminal can determine whether the Cell contains an always-on SSB based on the second parameter.

[0484] For example, a second parameter of 1 indicates that the cell contains always-on SSB, while a first parameter of 0 or no parameter is configured indicates that the cell does not contain always-on SSB.

[0485] For example, a first parameter value of 0 indicates that the cell does not contain always-on SSB, while a first parameter value of 1 or no first parameter configuration indicates that the cell contains always-on SSB.

[0486] In some embodiments, the terminal determines whether the Cell contains an OD-SSB and whether it contains an always-on SSB based on a third parameter.

[0487] For example, after determining that the Cell supports OD-SSB, the terminal can determine whether the Cell contains OD-SSB and whether it contains always-on SSB based on the third parameter.

[0488] For example, a value of 0 for the third parameter indicates that the cell contains both OD-SSB and always-on SSB; a value of 1 for the third parameter indicates that the cell contains both OD-SSB and always-on SSB.

[0489] For example, a value of 0 for the third parameter indicates that the cell contains OD-SSB and always-on SSB; a value of 1 for the third parameter indicates that the cell contains OD-SSB; and no third parameter is configured, indicating that the cell contains always-on SSB.

[0490] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0491] In this way, the network device indicates the SSB configuration type of the cell to the terminal by using the indication parameter method, so that the terminal can determine the SSB configuration type sent by the SSB in the cell. At the same time, the parameter configuration method can reduce the overhead in the signaling indication process and improve the communication performance of the communication system.
