It should be noted that this application embodiment only uses core network equipment in the NR system as an example and does not limit the specific type of core network equipment. If the name of the core network equipment mentioned in this application embodiment changes in subsequent protocol versions (e.g., 6G), it will still be within the scope of protection of this application.

[0061] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0062] In some embodiments, On-Demand SSB (OD-SSB) is a standard technology introduced for network energy saving. In some related technologies, network SSBs are transmitted according to a pre-configured period for terminals to perform cell search and synchronization. With the introduction of OD-SSB, on some cells and frequencies, the network can discontinue transmitting SSBs according to a period, or even completely stop transmitting SSBs when no terminal is connected to that frequency, only transmitting them when there is a genuine need.

[0063] For example, in the following inter-frequency deployment scenario, as shown in Figure 2, network-side equipment can transmit SSBs on frequency point f1 according to traditional behavior and a pre-configured period for terminals to perform cell search and synchronization. When the number of users in the cell is large, coverage based solely on the carrier corresponding to f1 is insufficient to meet the communication needs of multiple users, causing communication congestion. In this case, the network can consider further activating the carrier corresponding to f2. At this time, OD-SSBs can be transmitted on f2. When the number of users decreases, the network can stop transmitting OD-SSBs. Since SSBs no longer need to be transmitted periodically, the network can completely shut down the carrier corresponding to f2 and related radio frequency devices during the time when OD-SSBs are not transmitted, achieving network energy saving.

[0064] For example, in the following inter-frequency deployment scenario, as shown in Figure 2, another method to achieve network energy saving is to assume that on the carrier corresponding to f2, the network-side equipment transmits ordinary SSBs with a longer period, such as 160ms. When the number of users in the cell increases, the network-side equipment needs to accelerate the measurement and secondary cell activation processes for each terminal user in the cell corresponding to f2, thereby achieving rapid radio resource management and improving network efficiency. In this case, the network-side equipment can transmit a denser period SSB, i.e., OD-SSB, on the third frequency point f3. When the number of users in this cell is small, the denser period SSB on f3 can be turned off, thereby achieving the goal of network energy saving.

[0065] In some embodiments, for multi-TRP scenarios, such as the FR1 high-speed rail scenario, each cell contains multiple remote radio heads (RRHs), i.e., multiple TRPs. In some scenarios, the multiple TRPs can be time-division multiplexed, meaning that any terminal can connect to one TRP at any given time, as shown in Figure 3.

[0066] In some embodiments, the network-side device can configure two TRPs for a terminal simultaneously, and the two TRPs can schedule the terminal at the same time. The two TRPs belong to different control resource sets under the same logical cell, and the UE needs to listen for DCIs (Dispatch Information) from the two different control resource sets according to the network configuration.

[0067] In some embodiments, for multi-TRP scenarios, network-side devices can configure two different TRPs across physical cells for the terminal. The technical principle is similar to treating the TRP of physical cell 2 as a logical TRP under physical cell 1, analogous to cell 1 "borrowing" a TRP from cell 2. Because they belong to different physical cells, the synchronization error between TRPs may exceed the CP of the corresponding carrier. For such scenarios, the protocol further defines independent beam failure recovery processes between different TRPs, independent uplink timing advance management processes between different TRPs, and so on.

[0068] Combining multi-DCI and multi-TRP transmission within the same cell and across cells can effectively solve the robustness problem caused by a terminal connecting to only one TRP.

[0069] In some embodiments, a dedicated cell search module (i.e., Searcher) is implemented in typical 5G NR terminal implementations to search for cell synchronization signals. Before the cell search, the time-frequency synchronization information of the cell may be completely missing. The network can provide some basic synchronization information through configuration signaling, such as SS / PBCH block measurement timing configuration, the approximate location of the SMTC, and the approximate location of the SSB corresponding to a certain sequence number, etc. However, the actual reception timing of each SSB needs to be obtained through the cell search module. Therefore, the cell search module is generally based on multiple Fast Fourier Transform (FFT) windows. Optimal time-frequency domain synchronization is obtained through multiple searches in the time and frequency domains. Even for the serving cell, synchronization loss may occur due to a low signal-to-noise ratio (SNR). Once synchronization is lost, recovery generally requires cell search and measurement using multiple FFT windows.

[0070] In some embodiments, for multi-frequency deployment scenarios, network-side equipment can configure serving cell measurements for the terminal. For carrier aggregation, different types of serving cells have different usage patterns in the cell search module. For example, assuming the terminal is equipped with two Searchers, the primary carrier component (PCC) frequency corresponding to the primary cell (PCell) is generally assumed to occupy a separate Searcher, while the serving cell measurements of the primary SCG cell (PSCell) and the secondary cell (SCell) generally share the other Searcher.

[0071] In some embodiments, some cells can employ SSB-free secondary cell technology to save energy. For SSB-free secondary cells, based on the cross-carrier synchronization information provided by the network-side equipment, the terminal needs to use the tracking reference signal (TRS) transmitted on the secondary cell to further achieve synchronization and automatic gain control (AGC) adjustment. Compared to SSB, TRS itself has a weaker ability to handle time-domain synchronization errors. Therefore, SSB-free secondary cells generally impose strict requirements on the network, namely, the synchronization error between the downlink receiving timing reference cell and the corresponding secondary cell cannot exceed the cyclic prefix (CP) length of the secondary cell.

[0072] The following description, in conjunction with the accompanying drawings, details the cell information processing method, transmission method, apparatus, terminal, and network-side equipment provided in this application through some embodiments and application scenarios.

[0073] Please refer to Figure 4, which is a flowchart of a cell information processing method provided in an embodiment of this application. As shown in Figure 4, it includes the following steps:

[0074] Step 401: The terminal receives first information, which is used to indicate the synchronization information between the first cell and the second cell;

[0075] Step 402: When the synchronization information determines that the first condition is met, the terminal receives the first SSB of the second cell and performs at least one of cell measurement and cell activation of the second cell based on the first SSB.

[0076] The first condition includes at least one of the following:

[0077] The timing difference between the first cell and the second cell is less than or equal to a first preset value;

[0078] The difference in received power between the first cell and the second cell is less than or equal to a second preset value.

[0079] The aforementioned first information may be the first information received by the terminal in the serving cell, that is, the first information sent by the network-side device of the serving cell.

[0080] The aforementioned first SSB can be understood as the SSB of the second cell, and can represent any or all SSBs of the second cell, or the SSB of the second cell received by the terminal.

[0081] In some implementations, the first information mentioned above may be the first information received by the terminal in the first cell, for example: the first cell is the serving cell of the terminal, such as PCell.

[0082] In some implementations, the second cell may be a secondary serving cell, PSCell, or SCell of the terminal.

[0083] The aforementioned synchronization information can be time-frequency domain synchronization information.

[0084] In some implementations, the synchronization information may indicate the synchronization relationship between the first cell and the second cell, such as indicating that the first cell and the second cell are synchronized, or the synchronization information may be used to indicate that the first cell and the second cell meet the first condition.

[0085] The aforementioned first and second preset values ​​can be agreed upon in the protocol or configured by the network-side equipment. The specific values ​​can be configured according to actual conditions, and this application embodiment does not limit this. For example, the aforementioned first preset value can be the duration corresponding to the Cyclic Prefix (CP) of the second cell, or the aforementioned first preset value can be the duration corresponding to the CP of the first cell, or the aforementioned first preset value can be the duration corresponding to the shortest CP between the first and second cells, or the aforementioned first preset value can be 3 microseconds or 5 microseconds, etc. As another example, the aforementioned second preset value can be 10dB, 12dB, 15dB, etc.

[0086] The timing difference between the first cell and the second cell mentioned above is less than or equal to the first preset value, which can be the receiving timing difference between the first cell and the second cell being less than or equal to the first preset value.

[0087] In some implementations, the timing difference between the first cell and the second cell may be the timing difference indicated by the synchronization information, or the timing difference between the first cell and the second cell may be the actual timing difference, such as the actual timing difference measured by the terminal.

[0088] In some implementations, the received power difference between the first cell and the second cell may be the received power difference indicated by the synchronization information, or the received power difference between the first cell and the second cell may be the actual received power difference, such as the actual received power difference measured by the terminal.

[0089] The aforementioned determination that the synchronization information satisfies the first condition can be achieved by using the synchronization information itself, such as the first information indicating relevant information about the timing difference or received power difference, or the synchronization information satisfying the first condition. Alternatively, the determination that the synchronization information satisfies the first condition can be based on a judgment triggered by the first information, such as determining that the first condition is satisfied based on the actual timing difference or received power difference triggered by the first information.

[0090] The first condition mentioned above, including at least one of the above, can be understood as at least one of the following:

[0091] If the timing difference between the first cell and the second cell is less than or equal to the first preset value, perform step 402 above.

[0092] If the difference in received power between the first cell and the second cell is less than or equal to the second preset value, the above step 402 is executed;

[0093] If the timing difference between the first cell and the second cell is less than or equal to the first preset value, and the receiving power difference between the first cell and the second cell is less than or equal to the second preset value, then step 402 is executed.

[0094] In some implementations, satisfying the first condition above can indicate that the first cell and the second cell are synchronized or have a quasi-co-location (QCL) relationship. That is, if the synchronization information above determines that the first cell and the second cell are synchronized or have a QCL relationship, then step 402 above is executed.

[0095] The above-mentioned execution of cell measurement and cell activation of the second cell based on the first SSB includes at least one of the following:

[0096] Cell measurements of the second cell are performed based on the first SSB;

[0097] Cell activation of the second cell is performed based on the first SSB;

[0098] Cell measurement and cell activation of the second cell are performed based on the first SSB.

[0099] The specific implementation methods for cell measurement and cell activation can refer to the methods already defined in the protocol, or the methods newly defined in subsequent protocols, and are not limited in this application embodiment.

[0100] In this embodiment of the application, cell measurement refers to measurement events based on the configuration of the serving cell, such as performing Layer 3 measurements on the serving cell or non-serving cells (e.g., neighboring cells).

[0101] In this embodiment of the application, cell activation refers to the terminal activating the transmit and receive links of the secondary cell based on network indication signaling. This may include downlink synchronization, uplink synchronization (on demand), beam alignment, etc. In essence, it is also to measure the serving cell, but these measurements are unrelated to the measurement events configured for the serving cell.

[0102] It should be noted that the name of SSB is not limited in the embodiments of this application. For example, other names can be used for SSB in 6G or 7G systems. In the embodiments of this application, the first cell and the second cell can be two cells under the same system or two cells under different systems. For example, the first cell can be a 5G cell and the second cell can be a 6G cell.

[0103] In the embodiments of this application, the above steps can realize at least one of cell measurement and cell activation of the second cell based on SSB under the first condition, so that the terminal does not perform cell search under the first condition, thereby improving the efficiency of cell measurement or cell activation.

[0104] As an optional implementation, the first SSB mentioned above is an OD SSB.

[0105] In this implementation, since the SSB of the second cell is an OD SSB, the network-side equipment can send SSBs on demand, thereby saving the power consumption of the network-side equipment.

[0106] As an optional implementation, the time taken for the terminal to complete at least one of cell measurement and cell activation is less than or equal to the first duration;

[0107] Wherein, the number of SSB transmission opportunities included in the first time period is less than the target number of SSB transmission opportunities, and the target number of SSB transmission opportunities is the number of SSB transmission opportunities required for the terminal to search for a cell under the target SNR.

[0108] The time for the terminal to complete at least one of cell measurement and cell activation is less than or equal to a first duration can be defined as the time from the start of cell measurement and cell activation to completion being less than or equal to the first duration. For example, as shown in Figure 5, the time from the terminal's execution of cell measurement or cell activation to completion of cell measurement or activation is equal to the first duration. The synchronization relationship in Figure 5 can be understood as the aforementioned first condition, namely, the timing difference between the first cell and the second cell is less than or equal to a first preset value, and / or, the received power difference between the first cell and the second cell is less than or equal to a second preset value.

[0109] The aforementioned first duration may be agreed upon by the protocol or configured by the network-side equipment, or the aforementioned first duration may be calculated based on the aforementioned target number of SSB transmission opportunities.

[0110] The target SNR mentioned above is a relatively low SNR, such as -3dB or -6dB, which can be determined by protocol agreement or network-side device configuration.

[0111] The number of target SSB transmission opportunities can be determined based on the maximum time required for the terminal to search for a cell under the target SNR and the SSB transmission period. For example, the number of target SSB transmission opportunities can be determined based on the OD-SSB transmission period and the maximum time.

[0112] The maximum time mentioned above can be the upper limit of the time required for the terminal to search for the cell under the target SNR.

[0113] In this embodiment, since the number of SSB transmission opportunities included in the first time period is less than the target number of SSB transmission opportunities, the first time period can be less than the time required for the terminal to search for the cell under the target SNR, thereby further improving the efficiency of cell measurement or cell activation.

[0114] In some implementations, under the first condition, the time taken for the terminal to complete at least one of cell measurement and cell activation is less than or equal to the first duration may take effect if at least one SSB in the OD-SSB of the second cell has an SNR higher than a preset value. That is, the prerequisite for the first duration implementation is that at least one SSB in the OD-SSB of the second cell has an SNR higher than the preset value, and this can be that at least one SSB in the OD-SSBs with synchronization relationships indicated by the first information has an SNR higher than the preset value. The preset value may be agreed upon by a protocol or configured by the network-side equipment, and this preset value may be the same as or different from the second preset value.

[0115] This improves the reliability of cell measurement or cell activation because at least one SSB has an SNR higher than the preset value.

[0116] As an optional implementation, the method further includes:

[0117] Under the second condition, the terminal receives the second SSB of the second cell, performs cell search of the second cell based on the second SSB, and performs at least one of cell measurement and cell activation of the second cell based on the cell search result.

[0118] The second condition includes at least one of the following:

[0119] The timing difference between the first cell and the second cell is greater than the first preset value;

[0120] The difference in received power between the first cell and the second cell is greater than the second preset value.

[0121] The aforementioned second SSB can be understood as the SSB of the first cell, and can represent any or all SSBs of the first cell, or the SSB of the first cell received by the terminal.

[0122] In some implementations, satisfying the second condition can also be understood as not satisfying the first condition, that is, the synchronization information satisfies the second condition. For example: if the first condition is satisfied, step 402 is executed; if the first condition is not satisfied, the step of performing cell search for the second cell based on the second SSB is executed.

[0123] In some implementations, the aforementioned satisfaction of the second condition may also occur after the synchronization information determines that the first condition is satisfied, at least one of cell measurement and cell activation of the second cell is performed by the terminal. During this process, the timing difference between the first cell and the second cell actually detected by the terminal is greater than the aforementioned first preset value and / or the received power difference between the first cell and the second cell is greater than the second preset value. That is, the timing difference and received power difference corresponding to the aforementioned second condition may be the actual timing difference and actual received power difference actually detected by the terminal. For example, as shown on the right side of Figure 5, the terminal first performs cell measurement or cell activation based on the attempted synchronization relationship (i.e., satisfying the first condition), finds that the first cell and the second cell actually satisfy the second condition (i.e., the actual synchronization relationship is not satisfied), performs cell search, and performs cell measurement or cell activation based on the cell search result.

[0124] In some implementations, satisfying the second condition can also be understood as the first cell and the second cell not satisfying the synchronization relationship and not having QCL, or the first cell and the second cell actually not satisfying the synchronization relationship or actually not having QCL.

[0125] In this embodiment, cell measurement or cell activation can be performed based on cell search results under the second condition, thereby improving the reliability of cell measurement or cell activation.

[0126] The second and first conditions described above enable different cell measurements or cell activations under different conditions. For example: When a terminal receives first information from a network-side device, indicating time-frequency domain synchronization information between a first cell and a second cell; when the actual reception timing difference between the first cell and the second cell does not exceed a first preset value and the reception power difference does not exceed a second preset value, the terminal receives the OD-SSB of the second cell and performs cell measurement and / or cell activation based on the synchronization information and power difference information, and the time for cell measurement and cell activation cannot exceed a first duration; when the actual reception timing difference between the first cell and the second cell exceeds the first preset value, or the reception power difference exceeds the second preset value, the terminal receives the OD-SSB of the second cell, performs cell search, and performs cell measurement and / or cell activation, and the time for cell measurement and / or cell activation cannot exceed a second duration.

[0127] In some embodiments, the method further includes:

[0128] The first SSB and the second SSB are the same SSB.

[0129] The above-mentioned "same SSB" can be understood as the first SSB and the second SSB being the same SSB. For example, the same SSB is transmitted on demand in the second cell, and the SSB is transmitted periodically in the second cell.

[0130] Since the first SSB and the second SSB are the same SSB, this allows the terminal to receive the same SSB under different conditions, so that cell measurement or cell activation can be performed based on the same SSB.

[0131] In some implementations, the first SSB and the second SSB may be different SSBs.

[0132] Optionally, under the second condition, the time taken for the terminal to complete at least one of cell measurement and cell activation is less than or equal to the second duration;

[0133] Wherein, the number of SSB transmission opportunities included in the second time period is greater than or equal to the target number of SSB transmission opportunities, wherein the target number of SSB transmission opportunities is the number of SSB transmission opportunities required for the terminal to search for a cell under the target SNR.

[0134] The aforementioned second duration may be agreed upon by the protocol or configured by the network-side equipment, or the aforementioned second duration may be calculated based on the aforementioned target number of SSB transmission opportunities.

[0135] The number of target SSB transmission opportunities mentioned above is given in the corresponding description of the above implementation method and will not be repeated here.

[0136] As shown in Figure 5, the time for the terminal to complete at least one of cell measurement and cell activation is less than or equal to the second duration, and the time from when the terminal starts performing cell measurement or cell activation to when the terminal completes it is equal to the second duration.

[0137] Since the number of SSB transmission opportunities included in the second time period is greater than or equal to the target number of SSB transmission opportunities, this ensures that the time for the terminal to complete at least one of cell measurement and cell activation under the second condition is greater than or equal to the time required for the terminal to search for the cell under the target SNR. This allows the terminal sufficient time to complete at least one of cell measurement and cell activation, thereby improving the reliability of cell measurement or cell activation.

[0138] Optionally, the second duration is determined based on a factor associated with the number of carriers configured with Layer 3 (L3) measurements, the carriers configured with Layer 3 measurements including at least one of the following:

[0139] In the second cell, the SSB is the carrier of the OD SSB;

[0140] There is no OD SSB carrier in the second cell;

[0141] Wherein, the terminal performs at least one of cell measurement and cell activation on each of the carriers configured with layer 3 measurement based on the second duration.

[0142] The aforementioned factors are based on factors used to calculate the second duration, such as the Carrier Specific Scaling Factor (CSSF). The calculation of the second duration based on these factors can be done using a protocol-defined method or a network-side configured method; no specific method is specified here.

[0143] The aforementioned factor, which is related to the number of carriers configured with Layer 3 measurements, can be determined by the number of carriers configured with Layer 3 measurements, such as if there is a preset mapping relationship between the two. Alternatively, the aforementioned factor can be a duration, and the aforementioned second duration includes at least the aforementioned factor. For example, in some embodiments, when the terminal performs cell measurements on a second cell, the search duration of the second cell includes the aforementioned factor, the magnitude of which depends on the number of carriers configured with L3 measurements.

[0144] The above-mentioned terminal performs cell measurement and cell activation on the carriers configured with Layer 3 measurement based on the second duration. This can be understood as the value of the above factor affecting not only the L3 measurement of the carrier corresponding to OD-SSB, but also all other carriers configured with L3 measurement. That is, the terminal performs cell measurement or cell activation on these carriers based on the second duration corresponding to the factor.

[0145] In the above embodiments, since the factor is related to the number of carriers configured with Layer 3 measurements, the setting of the second duration can be made more reasonable, thereby improving the reliability of terminal cell measurement or cell activation.

[0146] It should be noted that the factors in this application embodiment are not limited to being associated with the number of carriers configured with Layer 3 measurements. For example, in some embodiments, the above factors may also be pre-configured.

[0147] Optionally, the method further includes:

[0148] When the terminal receives a notification message indicating that it can receive OD SSB, and OD SSB activation is completed, the terminal updates the factor and updates the second duration based on the updated factor.

[0149] When the terminal receives a configuration message for configuring OD SSB, the terminal updates the factor and updates the second duration based on the updated factor.

[0150] The aforementioned notification message indicating that OD SSB can be received refers to a notification message sent by the network-side device to the terminal. This notification message informs the terminal that it can receive OD SSB, or it informs the terminal to start receiving OD SSB. However, whether the terminal receives the notification message immediately is determined by the terminal's behavior.

[0151] The aforementioned OD-SSB activation can be completed by the network-side device activating the corresponding OD-SSB via Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) signaling, or by the terminal receiving the signaling or completing its parsing or processing. For example, if the network-side device notifies the UE to begin receiving OD-SSBs via RRC, the update of the aforementioned factors will be performed after the RRC signaling demodulation is completed and the corresponding OD-SSB activation is finished.

[0152] When the terminal receives the configuration message for configuring the OD-SSB, the terminal can update the factor regardless of whether the MAC CE notifies the terminal that the OD-SSB can be received. This factor update is performed after the RRC has configured the frequency point corresponding to the OD-SSB. For example, the network-side device configures the OD-SSB for the corresponding carrier via RRC, and the terminal performs the factor update after decoding the corresponding RRC signaling.

[0153] The aforementioned factor update can be based on the number of carriers configured with Layer 3 measurements.

[0154] In the above embodiments, when the OD SSB activation is completed or when a configuration message for configuring the OD SSB is received, the factor can be updated so that the duration of the terminal's cell measurement or cell activation for the second cell is updated in a timely manner, thereby improving the reliability of the terminal's cell measurement or cell activation.

[0155] Optionally, the step of performing cell search for the second cell based on the second SSB, and performing cell measurement and cell activation for the second cell based on the cell search results, includes:

[0156] Based on the second SSB, perform cell search for the second cell, and based on the cell search results, perform at least one of the following: Layer 3 cell measurement (which may be referred to as L3 measurement) and cell activation for the second cell;

[0157] The second cell may or may not be equipped with Layer 1 (L1) measurement.

[0158] The above-mentioned second cell having or not having Layer 1 measurement can be understood as performing cell search of the second cell regardless of whether L1 measurement of the SSB frequency point is configured or not, provided that the above-mentioned second condition is met.

[0159] In this embodiment, cell search can be performed regardless of whether the second cell is configured with Layer 1 measurement, and at least one of Layer 3 cell measurement and cell activation can be performed under the second condition, so as to improve the reliability of cell measurement and cell activation.

[0160] It should be noted that, in the embodiments of this application, the second condition is not limited to performing layer 3 cell measurement, and layer 1 cell measurement can also be performed.

[0161] Optionally, if the second cell is configured with Layer 1 measurement, and the terminal's beam changes at least during the Layer 1 measurement in the second cell, the Layer 1 measurement time includes at least one of the cell search time and the measurement time of the Layer 3 cell measurement.

[0162] The time for the aforementioned Layer 1 measurement includes at least one of the cell search time and the Layer 3 cell measurement time. It can be the Layer 1 measurement update time plus at least one of the cell search time and the Layer 3 cell measurement time. For example, for millimeter wave bands, assuming the network-side equipment indicates the terminal beam information for uplink and / or downlink transmission, in the corresponding L1 measurement, once the terminal's beam changes, the terminal needs to determine the beam based on the cell search process. Therefore, the L1 measurement update time also needs to include the L3 measurement or cell search time.

[0163] The second cell mentioned above is equipped with Layer 1 measurement, which can be L1 measurement with only OD-SSB configured.

[0164] In this embodiment, since the time for Layer 1 measurement includes at least one of the search time for cell search and the measurement time for Layer 3 cell measurement, the terminal has enough time to complete the cell measurement, thereby improving the reliability of cell measurement.

[0165] As an optional implementation, the synchronization information is used to represent at least one of the following:

[0166] The timing difference between the first cell and the second cell is less than or equal to the first preset value;

[0167] The difference in received power between the first cell and the second cell is less than or equal to the second preset value.

[0168] The aforementioned synchronization information may be an explicit indication of at least one of the above, or an implicit indication of at least one of the above, such as the synchronization information indicating that the first cell and the second cell satisfy the synchronization relationship, that is, implicitly indicating at least one of the above.

[0169] In this embodiment, since the above synchronization information represents at least one of the above, the terminal can directly determine that the first condition is met based on the above synchronization relationship, thereby saving the terminal's computing overhead.

[0170] It should be noted that, in the embodiments of this application, the above synchronization information is not limited to indicating at least one of the above. For example, the above synchronization information may indicate the timing information or received power information of the first cell and the second cell, and the timing difference is calculated by the terminal.

[0171] Optionally, the synchronization information is used to represent at least one of the following:

[0172] The timing difference between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the first preset value.

[0173] The difference in received power between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the second preset value.

[0174] Alternatively, the synchronization information may be used to represent at least one of the following:

[0175] The timing difference between any SSB of the first cell and any SSB of the second cell is less than or equal to the first preset value;

[0176] The difference in received power between any SSB of the first cell and any SSB of the second cell is less than or equal to the second preset value.

[0177] The third SSB mentioned above can be the designated SSB of the first cell, and the fourth SSB mentioned above can be the designated SSB of the second cell. For example, the designated SSB of the first cell and the designated SSB of the second cell have a synchronization relationship. For example, the network-side equipment indicates through signaling that the designated SSB of the first cell and the designated SSB of the second cell have a synchronization relationship, and the timing difference between them is less than a first preset value.

[0178] In some implementations, the third SSB may include the second SSB of the first cell, or the second SSB of the first cell may include the third SSB.

[0179] In some implementations, the fourth SSB includes the first SSB of the second cell, or the first SSB of the second cell includes the fourth SSB.

[0180] In the above embodiments, indicating the third and fourth SSBs can improve the accuracy of the synchronization relationship by indicating the synchronization relationship between specific SSBs. For example, in addition to indicating the synchronization relationship between the first cell and the second cell through the first information, the network-side device also indicates which specific SSBs have a synchronization relationship through the indication information under the first information.

[0181] The timing difference between any SSB of the first cell and any SSB of the second cell being less than or equal to the first preset value can be understood as the timing difference between all SSBs of the first cell and all SSBs of the second cell being less than or equal to the first preset value.

[0182] The statement that the difference in received power between any SSB of the first cell and any SSB of the second cell is less than or equal to the second preset value can be understood as the difference in received power between all SSBs of the first cell and all SSBs of the second cell being less than or equal to the second preset value.

[0183] By indicating any SSB of the first cell and any SSB of the second cell, it is possible to achieve a relationship before a specific SSB without indicating that specific SSBs exist, thus saving signaling overhead.

[0184] In some implementations, the synchronization information may be used to represent at least one of the following when at least one SSB exists in the first cell and / or the second cell, i.e., when the network informs the terminal via RRC signaling that there are more than one SSB sequence number in the first cell and / or the second cell:

[0185] The timing difference between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the first preset value.

[0186] The difference in received power between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the second preset value.

[0187] In some implementations, the synchronization information may be used to represent at least one of the following when at least one SSB exists in the first cell and / or the second cell, i.e., when the network informs the terminal via RRC signaling that there are more than one SSB sequence number in the first cell and / or the second cell:

[0188] The timing difference between any SSB of the first cell and any SSB of the second cell is less than or equal to the first preset value;

[0189] The difference in received power between any SSB of the first cell and any SSB of the second cell is less than or equal to the second preset value.

[0190] As an optional implementation, the terminal's behavior further includes at least one of the following:

[0191] If the first information does not indicate the synchronization information between the fifth SSB of the first cell and the sixth SSB of the second cell, the terminal cannot assume that the fifth SSB of the first cell and the sixth SSB of the second cell have a synchronization relationship.

[0192] The above synchronization information represents at least one of the timing relationship and the received power relationship between the two SSBs.

[0193] The fifth SSB of the first cell and the sixth SSB of the second cell can be understood as SSBs not indicated by the first information. For example, if the SSBs indicated by the first information are the third SSB and the fourth SSB, then the fifth SSB and the sixth SSB are SSBs other than the third SSB and the fourth SSB.

[0194] In this implementation, the terminal cannot assume that the fifth SSB of the first cell and the sixth SSB of the second cell are synchronized when the first information is not indicated, so as to avoid the terminal directly performing cell measurement or cell activation based on the corresponding SSB without indication, thereby improving the reliability of cell measurement or cell activation.

[0195] In some implementations, if the first information indicates that there is a synchronization relationship between the third SSB of the first cell and the fourth SSB of the second cell, and if the network signaling does not indicate that there is a synchronization relationship between the seventh SSB of the second cell and any SSB of the first cell, then the terminal cannot assume any known synchronization relationship during the measurement and cell search of the seventh SSB.

[0196] In some implementations, the synchronization information may be that the first cell and the second cell have a synchronization relationship. Based on the synchronization information indication and the actual difference in reception timing and reception power between the first cell and the second cell, the terminal determines the first condition or the second condition to perform different terminal behaviors. The terminal behaviors under the first condition and the second cell correspond to the same or different Radio Resource Management (RRM) indicators.

[0197] In some implementations, the aforementioned difference in received power can be a difference in received signal strength.

[0198] As an optional implementation, the OD SSB includes at least one of the following:

[0199] OD SSB for beam failure detection (BFD);

[0200] OD SSB for candidate beam detection (CBD).

[0201] In this implementation, the OD-SSB can be configured as an SSB for the BFD and / or CBD processes to save on network-side equipment overhead and transmission overhead in these two processes.

[0202] It should be noted that the OD SSB in the embodiments of this application is not limited to the two types of OD SSBs mentioned above, and may also be an SSB with other functions, which is not limited.

[0203] Optionally, the transmission time of the OD SSB for CBD is later than the transmission time of the first beam failure recovery (BFR) information transmitted by the terminal, and the method further includes:

[0204] When the terminal completes at least one of cell measurement and cell activation based on the OD SSB for candidate beam detection CBD, the terminal sends second BFR information;

[0205] Wherein, the amount of data in the second BFR information is greater than the amount of data in the first BFR information;

[0206] The second BFR information includes the recovery beam information during the beam failure recovery process.

[0207] The transmission time of the OD SSB for CBD is later than the transmission time of the first BFR information sent by the terminal, which may trigger the transmission of the OD SSB for CBD by the first BFR information.

[0208] The first BFR information and the second BFR information mentioned above can be MAC CE sent by the terminal to the network-side device. For example, the first BFR information is a short BFR MAC CE, and the second BFR is a normal BFR MAC CE.

[0209] In some implementations, the first BFR information may not include the recovery beam information during the beam failure recovery process. For example, when the OD-SSB of the second cell is configured as the SSB for the CBD process, the transmission of the OD-SSB is based on a short BFR MAC CE sent by the terminal. This short BFR MAC CE does not contain beam failure recovery reporting information. After the short BFR MAC CE is reported, the network triggers the transmission of the OD-SSB, the terminal performs the OD-SSB measurement, and completes the reporting of the normal BFR MAC CE.

[0210] In this implementation, the network-side device can send the OD SSB only after the terminal reports the first BFR, which can improve the success rate of the terminal receiving the OD SSB. Furthermore, since the data volume of the second BFR information is greater than that of the first BFR information, the transmission overhead of BFR information can be saved by sending the SSB during reception.

[0211] As an optional implementation, the first cell and the second cell satisfy at least one of the following:

[0212] The first cell and the second cell have different SSB frequencies;

[0213] The first cell and the second cell belong to different frequency bands;

[0214] The second cell is a secondary serving cell, and it was inactive when the first information was sent.

[0215] The aforementioned SSB frequency point is the center frequency point of the SSB, determined based on the absolute frequency point number configured in the network. For example, network-side equipment can configure a cell-defined SSB (CD-SSB) or a non-cell-defined SSB (NCD-SSB) frequency point for each cell. The difference between the SSB frequencies of the first and second cells mentioned above includes at least two cases where the CD-SSB frequencies of the two cells are different, or where the NCD-SSB frequencies of the two cells are different.

[0216] The aforementioned first information is sent to the terminal by the network-side device via a first signaling. When the terminal receives the first information, the second cell is in an inactive state, but the first signaling may contain an indication to activate the second cell. Even after receiving the first signaling, the terminal needs to complete necessary procedures such as measurement before it can change from an inactive state to an active state.

[0217] The fact that the first cell and the second cell belong to different frequency bands can be understood as the first cell and the second cell being out-of-band cells.

[0218] The aforementioned frequency bands are a subset of frequency ranges defined by the protocol. Within this subset, terminals can search for networks using a predefined set of synchronization frequencies to access the network within that frequency band. Within each frequency range subset, both the network and the terminal need to meet specific radio frequency consistency requirements. These frequency bands have uniformly defined band numbers. For example, the 700MHz band is generally referred to as band number 28, and the 2.6GHz band is generally referred to as band number 41, and so on.

[0219] This implementation can save the cell search process and improve terminal efficiency for cells with different SSB frequencies or different frequency bands, provided that the first condition mentioned above is met. It can also save the cell search process for secondary serving cells, thereby improving terminal efficiency.

[0220] As an optional implementation, the first information satisfies at least one of the following:

[0221] The first information is transmitted via system message signaling;

[0222] The first information applies to the target terminal;

[0223] The receiving terminal of the first information is the target terminal;

[0224] The target terminal supports completing at least one of cell measurement and cell activation within a first time period based on the first information.

[0225] The aforementioned system message signaling can be RRC signaling. It should be noted that the transmission method of the first information is not limited in this embodiment of the application. For example, it can also be sent through terminal-specific signaling or other broadcast signaling.

[0226] The aforementioned target terminal's ability to complete at least one of cell measurement and cell activation within a first time period based on the first information can be understood as the target terminal having the capability to complete at least one of cell measurement and cell activation within a first time period based on the first information, i.e., the terminal having the capability to reduce the time for at least one of cell measurement and cell activation to within a first time period.

[0227] Since the first information takes effect on the target terminal, this avoids cell measurement or cell activation failures caused by terminals that do not support the above capabilities responding to the first information.

[0228] Since the receiving terminal of the first information is the target terminal, the network-side equipment can send information only to the target terminal, thereby saving transmission resources.

[0229] In this embodiment of the application, the terminal that performs steps 401 and 402 is the aforementioned target terminal.

[0230] As an optional implementation, the method further includes:

[0231] The terminal reports capability information, which indicates that it supports completing at least one of cell measurement and cell activation within a first time period based on the first information.

[0232] The aforementioned capability information can be found in the description of the target terminal.

[0233] The aforementioned terminal-reported capability information refers to the capability information reported by the terminal to the network-side equipment.

[0234] In this embodiment, by reporting the aforementioned capability information, the network-side device can send the aforementioned first information to the terminal, thereby avoiding the network-side device from sending the first information to a terminal that does not support the aforementioned capability, thus saving transmission overhead.

[0235] In this embodiment, the terminal receives first information indicating synchronization information between a first cell and a second cell. When the synchronization information determines that a first condition is met, the terminal receives a first SSB (Secondary Support Bus) of the second cell and performs at least one of cell measurement and cell activation based on the first SSB. The first condition includes at least one of the following: the timing difference between the first cell and the second cell is less than or equal to a first preset value; the received power difference between the first cell and the second cell is less than or equal to a second preset value. This allows at least one of cell measurement and cell activation to be performed based on the SSB under the first condition, thereby eliminating the need for cell search under the first condition and improving the efficiency of cell measurement or cell activation.

[0236] Please refer to Figure 6, which is a flowchart of a cell information transmission method provided in an embodiment of this application. As shown in Figure 6, it includes the following steps:

[0237] Step 601: The network-side device sends first information to the terminal, the first information being used to indicate the synchronization information of the first cell and the second cell;

[0238] The synchronization information is used to represent at least one of the following:

[0239] The timing difference between the first cell and the second cell is less than or equal to a first preset value;

[0240] The difference in received power between the first cell and the second cell is less than or equal to a second preset value.

[0241] Optionally, the first SSB of the second cell is an on-demand OD SSB.

[0242] Optionally, the synchronization information is used to represent at least one of the following:

[0243] The timing difference between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the first preset value.

[0244] The difference in received power between the third SSB of the first cell and the fourth SSB of the second cell is less than or equal to the second preset value.

[0245] Alternatively, the synchronization information may be used to represent at least one of the following:

[0246] The timing difference between any SSB of the first cell and any SSB of the second cell is less than or equal to the first preset value;

[0247] The difference in received power between any SSB of the first cell and any SSB of the second cell is less than or equal to the second preset value.

[0248] Optionally, the first cell and the second cell satisfy at least one of the following:

[0249] The first cell and the second cell have different SSB frequencies;

[0250] The first cell and the second cell belong to different frequency bands;

[0251] The second cell is a secondary serving cell, and it was inactive when the first information was sent.

[0252] Optionally, the first information satisfies at least one of the following:

[0253] The first information is transmitted via system message signaling;

[0254] The first information applies to the target terminal;

[0255] The receiving terminal of the first information is the target terminal;

[0256] The target terminal supports completing at least one of cell measurement and cell activation within a first time period based on the first information.

[0257] Optionally, the method further includes:

[0258] The network-side device receives capability information reported by the terminal, the capability information being used to indicate: support for completing at least one of cell measurement and cell activation within a first time period based on the first information.

[0259] It should be noted that this embodiment is an implementation of the network-side device corresponding to the embodiment shown in Figure 4. For the specific implementation, please refer to the relevant description of the embodiment shown in Figure 4. In order to avoid repeated description, this embodiment will not be repeated.

[0260] The method provided in this application is illustrated below through a specific embodiment:

[0261] As shown in Figure 7, the network deployment uses two carriers, f1 and f2. On carrier f1, the network deploys a PCC (primary carrier) for idle-state UEs to access the network. On carrier f2, the network deploys a Secondary Cell Group (SCC), which is the secondary carrier for UEs to offload uplink and downlink data. When the number of users in a cell increases and the primary carrier cannot meet the needs of all users, the secondary carrier can be used to carry the data transmission requirements of the users.

[0262] The network-side device sends a first message indicating a synchronization relationship between f1 and f2. Based on this synchronization indication, when the UE performs cell activation on the secondary carrier, it determines whether a cell search needs to be performed on the corresponding secondary carrier. The specific process is shown in Figure 5. If the synchronization indication exists, the UE can skip the OD-SSB-based cell search and directly perform necessary AGC and fine synchronization adjustments on the secondary carrier based on OD-SSB to perform subsequent operations such as measurement or activation. In this case, the time taken for the UE to complete the measurement or cell activation does not exceed the first time interval.

[0263] However, considering the dynamic characteristics of network coverage scenarios and wireless propagation features, after the network issues a synchronization indication, the UE may find that the actual detected first and second cells cannot achieve the ideal synchronization index during the actual AGC and fine synchronization adjustment process, resulting in a decrease in actual reception performance or even failure to achieve synchronization. In this case, the UE needs to fall back to the situation where there is no synchronization indication between cells, perform cell search based on the indicated OD-SSB, and then perform cell measurement or cell activation. At this time, the time for the UE to complete the measurement or cell activation process does not exceed a second duration. The second duration is determined based on the OD-SSB period.

[0264] In the above embodiments, OD-SSB is used as the reference signal for cell search and AGC adjustment. Since the reference signal used for AGC adjustment can also be used for cell search, it increases the flexibility of UE implementation. Compared with some non-OD-SSB schemes, i.e. periodically sending SSB, it can also make good use of the on-demand sending feature to achieve network energy saving effect.

[0265] Optionally, if during actual AGC and fine synchronization adjustment, the UE discovers that the ideal synchronization index cannot be achieved between the detected first and second cells, and needs to fall back to a state where there is no synchronization indication between cells, then if the network also configures a non-OD-SSB on the second cell, the UE can also perform cell search based on the non-OD-SSB, and then perform cell measurement or cell activation. In this case, the time for the UE to complete the measurement or cell activation process does not exceed a second duration. The second duration is determined based on the non-OD-SSB period.

[0266] Optionally, the aforementioned first information is sent via system message or RRC signaling. Before the first information is sent, the UE reports relevant capabilities, instructing the UE to support indications related to the first information, and to reduce the time for secondary cell activation or cell measurement to within a first duration, as shown in Figure 8.

[0267] Specifically, f1 and f2 mentioned above can be different carriers or different SSB frequencies within the same frequency band. f2 can be the SSB frequency corresponding to a non-cell-defined synchronization block (SSB). For example, if the first cell and the second cell happen to be the same cell, then f2 is the SSB frequency corresponding to a non-cell-defined synchronization block. Specifically, f1 and f2 can also be different carriers corresponding to different frequency bands.

[0268] Specifically, the aforementioned Cell Definition SSB indicates the scheduling status of the cell's system information. By decoding the Master Information Block (MIB) in the Cell Definition SSB, the UE can obtain the cell's system information scheduling location and then learn about the cell through system information broadcast throughout the cell. Non-Cell Definition SSBs (i.e., NCD-SSBs) generally do not indicate the scheduling status of the cell's system channels. When the UE receives and demodulates the NCD-SSB, it cannot obtain system information.

[0269] In some implementations, the second cell is a secondary serving cell. In this embodiment, when the first information is sent, the secondary serving cell may not yet be activated, i.e., it may be in an inactive state. Generally, the activation of a secondary serving cell requires the reception and decoding of RRC or MAC CE signaling, as well as the completion of UE processing corresponding to the activation process. Here, UE processing mainly involves measurements, including measurements for coarse synchronization acquisition, measurements for fine synchronization acquisition, measurements for acquiring the transmit / receive UE beam, etc. The UE's secondary serving cell being in an inactive state includes both the state where the UE has not yet received the secondary cell activation signaling and the state where the secondary cell activation signaling has been received, but the activation of the secondary cell has not yet been completed.

[0270] Optionally, the number of actual SSB transmission opportunities included in the first duration is less than the number of SSB transmission opportunities required for the UE to find the corresponding cell at a certain low SNR.

[0271] The number of actual SSB transmission opportunities included in the second duration mentioned above shall not be less than the number of SSB transmission opportunities required for the UE to search for the corresponding cell at a certain lower SNR; generally, the lower SNR defined by the protocol is -3dB or -6dB.

[0272] The aforementioned lower SNR refers to the search cell, and the required number of SSB transmission opportunities is the number of SSB transmission opportunities included in the upper limit requirement of the time required for the UE to search for the corresponding cell under this SNR.

[0273] The number of SSB transmission opportunities mentioned above is determined based on the transmission cycle and corresponding duration requirements of OD-SSB.

[0274] For example, if the coefficient before the SSB transmission opportunity in the calculation formula of the first duration is 2 or 1, and the protocol defines the coefficient before the SSB transmission opportunity required to find the corresponding cell under the condition of SNR=-6 as 3 or 5, then the actual number of SSB transmission opportunities included in the first duration is less than the number of SSB transmission opportunities required for the UE to find the corresponding cell under a certain low SNR.

[0275] For example, in the second duration calculation formula, the coefficient before the SSB transmission opportunity is 3 or 5. Since the protocol defines the coefficient before the SSB transmission opportunity required to find the corresponding cell under the condition of SNR = -6 as 3 or 5, the number of actual SSB transmission opportunities included in the second duration is not less than the number of SSB transmission opportunities required for the UE to find the corresponding cell under a certain lower SNR.

[0276] Instructions regarding the synchronization relationship between the first and second cells include the following two methods:

[0277] Method 1: Based on the aforementioned indication, the network side informs the UE that the reception timing difference between the SSB of the first cell and the SSB of any second cell is less than a first preset value, and the reception power difference is less than a preset value. Specifically, the first preset value may be the CP length corresponding to the second cell. The aforementioned reception power difference may be 12dB.

[0278] It should be noted that the number of SSBs in the first cell can be different from the number of SSBs in the second cell. For example, as shown in Figure 7 above, the first cell (f1) transmits one SSB, namely SSB0, and the second cell transmits four SSBs, namely SSB1, SSB2, SSB3, and SSB4. SSB0 is transmitted on all TRPs in the first cell, while SSB1 / 2 / 3 / 4 are transmitted individually on each TRP. The network ensures that, given the indicated information, the timing error of the UE receiving SSB0 from the first cell and SSB1 / 2 / 3 / 4 from the second cell at any point does not exceed the CP range by controlling the TRP deployment interval and the synchronization error between TRPs.

[0279] Method 2: The network-side equipment specifically specifies that the timing difference between a specific SSB in the first cell and a specific SSB in the second cell is less than a first preset value, and the received power difference is less than a second preset value. Specifically, the first preset value can be the CP length corresponding to the second cell, and the received power difference can be 12dB.

[0280] For example, the network configures the QCL relationship between SSBs to indicate that the timing difference between SSB1 of the first cell and OD-SSB and SSB2 of the second cell does not exceed the CP range.

[0281] For example, the network can use a mapping relationship to indicate that the timing difference between SSB1 of the first cell and OD-SSB and SSB2 of the second cell does not exceed the CP range, such as {SSB1: [SSB2]; SSB0: [SSB3]}.

[0282] In this indication method, if the network-side equipment signaling does not indicate that there is a synchronization relationship between the first SSB of the first cell and the third SSB of the second cell, the UE cannot assume that the two are synchronized.

[0283] For example, if there is no QCL relationship configured between SSB1 of the first cell and SSB3 of the second cell, or if there is no SSB3 in the mapping table corresponding to SSB1 of the first cell, the UE cannot assume that the two have a synchronization relationship.

[0284] Regarding this indication method, in deployment, if the SSB4 of the second cell does not have a co-location relationship with any SSB of the first cell, the network may not include the SSB4 of the second cell in any QCL indication or mapping relationship indication. In this case, if the UE initiates measurement and secondary cell activation based on SSB4, the reception duration indicator is the second duration.

[0285] Regarding indication methods 1 and 2, if the UE cannot find any of the SSBs of the first cell indicating the synchronization relationship (i.e., the SNR corresponding to these SSBs is too low), the UE can still attempt to search for the SSBs of cell 2 and complete the corresponding cell measurement and cell search for the second duration. In other words, the condition of not exceeding the first duration also includes that at least one SSB among the OD-SSBs of the second cell indicating the synchronization relationship has an SNR higher than a second preset value.

[0286] The following section provides a further explanation of the UE behavior characteristics related to the second duration.

[0287] If the conditions for using the first duration are not met, the UE will use the second duration to complete the measurement and cell activation of the corresponding second cell. At this time, the cell search process for the corresponding cell needs to be executed.

[0288] Optionally, if the operation of the corresponding second cell is cell measurement, the cell search duration will include a first factor (i.e., the factor in the above embodiment), the magnitude of which depends on the number of carriers configured with L3 measurement. The value of the first factor not only affects the L3 measurement of the carrier corresponding to the OD-SSB, but also affects all other carriers configured with L3 measurement.

[0289] For example, if the network is configured with one PCC and three SCCs without OD-SSB, and another SCC is configured with OD-SSB, then the first factor will not only affect the SCC configured with OD-SSB, but also the three SCCs without OD-SSB.

[0290] The specific ways in which this influence is exerted include one of the following two:

[0291] First Factor Calculation Method 1: As shown in Figure 9, the network first configures the OD-SSB of the corresponding carrier via RRC. Then, the network activates the corresponding OD-SSB via RRC signaling or MAC CE signaling. From the time the network triggers OD-SSB activation to the completion of OD-SSB activation, some processing time is generally allowed for the UE to perform baseband processing such as decoding and measurement scheduling. After the OD-SSB is activated, the UE performs the first factor calculation for all measurements, including the frequency layer corresponding to the OD-SSB in the calculation. When the corresponding OD-SSB is deactivated, the UE performs the first factor calculation for all measurements, excluding the frequency layer corresponding to the OD-SSB from the calculation.

[0292] Method 2 for calculating the first factor: As shown in Figure 10, the network first configures the OD-SSB of the corresponding carrier via RRC. After the UE completes the decoding of the corresponding RRC signaling, the UE executes all measured first factors, including the frequency layer corresponding to the OD-SSB in the calculation scope. Afterwards, regardless of whether the network activates the corresponding OD-SSB via RRC signaling or MAC CE signaling, the UE's first factor remains unchanged. Only when the RRC cancels the OD-SSB configuration will the UE exclude the frequency layer corresponding to the OD-SSB from the calculation scope of the first factor.

[0293] Specifically, one optional implementation is that, based on OD-SSB measurements, from the perspective of network-side device configuration, the UE can be configured solely through L1 measurement configuration. In this case, the UE still needs to perform cell search on the corresponding OD-SSB frequency layer as needed. That is, if the UE determines, based on a judgment condition, that it needs to perform the corresponding cell measurement and activation according to the second duration, then regardless of whether L1 measurement for the corresponding SSB frequency point is configured, the UE needs to perform cell search on the corresponding frequency layer. In other words, at this point, the UE determines whether to perform L3 measurement or cell search on the corresponding cell based on whether L1 measurement is configured. The time for the L1 measurement needs to include the time for the corresponding cell search.

[0294] Optionally, for millimeter wave bands, assuming the network will indicate the beam information for uplink and / or downlink transmission, in the corresponding L1 measurement, once the UE beam changes and this beam change exceeds the range of the UE's normal beam tracking capability, the UE needs to determine a new UE beam based on the cell search process, and the time for L1 measurement update also needs to be added to the time for L3 measurement or cell search.

[0295] Furthermore, the OD-SSB on the second cell can also be used when the corresponding second cell is activated. In this case, the OD-SSB is mainly used for time-frequency tracking and / or beam failure recovery. For example, the OD-SSB can be configured to detect the reference signal of a beam failure, or to recover the reference signal corresponding to the detected beam after a beam failure occurs.

[0296] Optionally, if the OD-SSB is configured for beam failure recovery to restore the reference signal corresponding to the detected beam, its transmission can be activated and transmitted after the UE reports a short BFR MAC CE. The short BFR MAC CE does not contain beam failure recovery reporting information. After the short BFR MAC CE is reported, the network triggers the transmission of the OD-SSB, the UE performs OD-SSB measurements, and completes the reporting of a normal BFR MAC CE. The normal BFR MAC CE contains beam recovery information.

[0297] Optionally, the triggering of the aforementioned OD-SSB shall be no later than the third time interval after the successful transmission of the UE's short BFR MAC CE, as shown in Figure 11. Assuming the UE reports beam failure information via the short BFR MAC CE, the network should trigger the transmission of the OD-SSB as soon as possible and notify the UE through corresponding signaling. If the network fails to transmit the OD-SSB in time within the third time interval after the successful transmission of the short BFR MAC CE, the UE will report a normal BFR MAC CE based on other reference signals, meaning it may miss the beam corresponding to the OD-SSB. If the UE cannot find other reference signals, causing the timer in the BFR process to time out, the UE will enter the Radio Link Failure (RLF) recovery procedure.

[0298] In this embodiment, when the network has explicit co-location information (such as the synchronization information mentioned above), the UE can be informed through indication information to reduce cell search time and improve the efficiency of measurement and connection establishment. When the network cannot provide explicit co-location information, or when the co-location information cannot effectively assist the UE in reducing cell search time overhead, the UE needs to perform SSB-based cell search and measurement on that cell. In this case, this embodiment designs a reuse method for the UE's internal cell search module, which reduces cost while ensuring efficiency.
