[0125] In step S2102, the terminal determines the cell switching type.

[0126] In some embodiments, the terminal can determine the cell switching type in a case where the first channel bandwidth of the satellite network is less than a first value and / or the number of resource blocks (RBs) of the first signal is less than a second value, and the cell switching type can assist in determining the first time related to the satellite network cell switching.

[0127] In some embodiments, the cell switching indicates that the terminal switches from a current access cell to a first cell, and the cell can be specifically, for example, a satellite network cell (SAN cell). The current access cell can be referred to as a source cell, and the first cell can also be referred to as a target cell, without limitation.

[0128] In some embodiments, the source cell and the first cell of the cell switching are respectively a frequency range 1 (FR1) cell. In this way, the impact of the search time for a low-frequency cell caused by a smaller test channel bandwidth or a reduction in resources occupied by SSB and / or PBCH can be supported.

[0129] In some embodiments, the cell switching type includes at least one of the following: an intra-frequency handover, an inter-frequency handover. In this way, the communication test scenario can be effectively extended.

[0130] In some embodiments, the terminal can autonomously determine the cell switching type; or the terminal can determine the cell switching type based on an indication and / or configuration of the network side; or the terminal can also determine the cell switching type based on a system protocol, without limitation.

[0131] In step S2103, the terminal determines the first time related to the satellite network cell switching according to the cell switching type.

[0132] The first cell in the embodiments of the present disclosure can refer to an unknown target cell. If the first cell is a known target cell, steps S2102-S2104 can not be performed, and the first time can be directly configured as 0 ms (milliseconds).

[0133] In some embodiments, after determining the cell switching type, the terminal can use the cell switching type to determine the first time related to the satellite network cell switching. The first time can be a search time for testing the first cell. The first time can be represented as T search .

[0134] In some embodiments, different cell switching types can correspond to different first times.

[0135] In the embodiments of the present disclosure, the first time related to satellite network cell switching can be adaptively adjusted in the case of a smaller channel bandwidth or a reduction in resources occupied by SSB and / or PBCH. The first time obtained by the adjustment can be used to test the search time of the first cell, so as to analyze the influence of the test channel bandwidth being smaller or the reduction in resources occupied by SSB and / or PBCH on the search time of the first cell, thereby supporting improving the effect of satellite network cell switching.

[0136] In some embodiments, in the case of a smaller channel bandwidth or a reduction in resources occupied by SSB and / or PBCH, the time for testing the search of the first cell can be relatively extended to obtain the first time. The time for testing the search of the first cell can be understood as the time for testing the search of the first cell configured in the case of a larger channel bandwidth or no reduction in resources occupied by SSB and / or PBCH.

[0137] In some embodiments, the terminal can use the first multiple and the second time to determine the first time in the case of determining that the cell switching type is intra-frequency switching. In the case of determining that the cell switching type is inter-frequency switching, the terminal can use the second multiple and the second time to determine the first time. The second multiple is greater than the first multiple.

[0138] The second time can be represented as T rs The value of the second time includes:

[0139] In the case of including the first SSB measurement timing configuration (SSB Measurement Timing Configuration, SMTC) period configured for the first cell in the switching command, the second time is equal to the first SMTC period. In the case of not including the first SMTC period configured for the first cell in the switching command, the second time is equal to the second SMTC period. The second SMTC period is the SMTC period of the first SSB frequency and subcarrier spacing configured for the measurement object, and the first SSB frequency and subcarrier spacing are the same as the second SSB frequency and subcarrier spacing configured for the carrier of the network device.

[0140] The SMTC period included in the switching command and configured for the first cell can be referred to as the first SMTC period.

[0141] The SSB frequency and subcarrier spacing configured for the measurement object can be referred to as the first SSB frequency and subcarrier spacing. The first SSB frequency and subcarrier spacing are the same as the second SSB frequency and subcarrier spacing configured for the carrier of the network device (referring to the network device serving the terminal).

[0142] The first SSB frequency and subcarrier spacing can be associated with a SMTC period, and the SMTC period associated with the first SSB frequency and subcarrier spacing can be referred to as a second SMTC period.

[0143] That is, the second time can be defined according to whether the SMTC period configured for the first cell is included in the handover command. For example, if the SMTC period configured for the first cell is included in the handover command, the second time can be directly determined to be equal to the second SMTC period. If the SMTC period configured for the first cell is not included in the handover command, the second time is equal to the second SMTC period, and the definition of the second SMTC period can refer to the description above.

[0144] In some embodiments, the first multiple is 3 and the second multiple is 5.

[0145] In some embodiments, some boundary conditions can also be configured. In the case where the first SMTC period configured for the first cell is included in the handover command and the boundary conditions are met, the second time is configured to be equal to the first SMTC period. The boundary conditions can be, for example, the E s / I ot The energy per synchronization signal resource element (RE) divided by the total energy of the received noise and interference (defined as E s / N o ) is at least -2 dB, which is not limited.

[0146] In this way, the accuracy of the definition of the first time can be ensured, and the influence of the reduction of the channel bandwidth or the occupied resources of the SSB and / or PBCH on the search time of the first cell can be accurately analyzed.

[0147] At step S2104, the first cell is searched within the first time.

[0148] After determining the first time related to the satellite network cell switching according to the cell switching type, the first cell can also be searched within the first time. For example, the first time can be used as a constraint condition for the terminal to search for the first cell, so as to test the search time of the first cell and analyze the influence of the reduction of the channel bandwidth or the occupied resources of the SSB and / or PBCH on the search time of the first cell.

[0149] The information determination method related to the embodiments of the present disclosure can include at least one of steps S2101-S2104. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, and so on, but is not limited thereto. Steps S2101+S2102 can be implemented as an independent embodiment, steps S2101+S2102+S2103 can be implemented as an independent embodiment, but are not limited thereto.

[0150] In the present embodiment or example, each step can be independent, arbitrarily combined or the order exchanged, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples without contradiction.

[0151] In the present embodiment, the network device can determine that the first channel bandwidth of the satellite network is less than a first value and / or the resource block (RB) quantity of the first signal is less than a second value, the terminal determines the cell switching type, determines the first time related to the satellite network cell switching according to the cell switching type, and searches for the first cell within the first time. Thus, the first time related to the satellite network cell switching is adaptively adjusted in the case of reduced channel bandwidth or reduced SSB and / or PBCH resource occupation, and the adjusted first time can be used to test the time for the terminal to search for the first cell, thereby supporting the influence of the search time for the first cell brought by the reduced channel bandwidth or reduced SSB and / or PBCH resource occupation, and thus supporting the improvement of the satellite network cell switching effect.

[0189] FIG. 5 is an interaction diagram of an information determination method according to still another embodiment of the present disclosure. As shown in FIG. 5, the embodiments of the present disclosure relate to an information determination method, which can be used in a communication system. The above method comprises:

[0190] In step S5101, the network device determines that the first channel bandwidth of the satellite network is less than a first value and / or the number of resource blocks (RBs) of the first signal is less than a second value.

[0191] In step S5102, the terminal determines a first time related to cell switching of the satellite network, wherein the first time is used to test the search time for the first cell.

[0192] The information determination method related to the embodiments of the present disclosure can comprise at least one of steps S5101-S5102. For example, step S5101 can be implemented as an independent embodiment, step S5102 can be implemented as an independent embodiment, and so on, but is not limited thereto.

[0193] In the present embodiment or the present example, each step can be independently combined or exchanged in order, the optional mode or the optional example can be combined arbitrarily, and can be combined with any step of other embodiments or other examples.

[0194] The following is an exemplary introduction to the above method.

[0195] Optional example:

[0196] Taking the first cell as the target cell as an example.

[0197] The interruption time (T interrupt ) can be defined as follows: T interrupt = T search + T IU + T processing + T Δ + T margin ms.

[0198] wherein T search is the search time of the terminal for the unknown first cell, T IU is the interruption uncertainty time for the terminal to acquire the first available PRACH resource in the new cell, which is different for different PRACH configurations, T Δ represents the fine synchronization time of the terminal with the target cell, T processing represents the processing time of the terminal, T margin is the time for post-processing of SSB.

[0199] The corresponding extension of T search is described as follows:

[0200] When the terminal receives the handover command, if the target cell is unknown, the time required for searching the target cell can be defined as T search . If the target cell is known, T search = 0 ms. If the target cell is an unknown target cell, and the cell handover type is intra-frequency handover, and the E s / I ot of the target cell is greater than or equal to -2 dB, then T search = 3 * T rs ; wherein T rs is an optional example of the second time described above, otherwise, T search = T rs . If the target cell is an unknown target cell, and the cell handover type is inter-frequency handover, and the E s / I ot of the target cell is greater than or equal to -2 dB, then T search = 5 * T rs ; otherwise, T search = 3 * T rs .

[0201] wherein if the SMTC configuration is provided for the target cell (target SAN cell) in the handover command, T rs is the SMTC period of the target cell, otherwise T rs is the SMTC period with the same SSB frequency and subcarrier spacing configured in the parameters of measObjectNR (an optional example of measurement object). In addition, if the terminal is not configured with the SMTC configuration or the parameters of the measurement object. If the SSB transmission period is 5 ms, T rs = 5 ms can be configured. If the SSB transmission period is not 5 ms, T rs is not required. If the smtc2 has been configured for the terminal through high layer signaling before the handover command, Trs The SMTC1 or SMTC2 corresponding to the target cell can be followed.

[0202] In the embodiments of the present disclosure, in the case of reduction of the channel bandwidth or reduction of the resources occupied by the SSB and / or PBCH, the T search corresponding extension processing is performed, so that the terminal can use multiple SMTCs to detect the unknown target cell after receiving the handover command. The success rate of the terminal detecting the PBCH in multiple SMTCs is improved. When the signal to interference plus noise ratio (SINR) is lower than a certain threshold, the terminal can use more SMTCs to detect the unknown target cell.

[0203] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device comprising units or modules for implementing each step performed by the terminal in any of the above methods.
