[0144] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems using other frequency band switching methods, and next-generation systems based on these systems. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A with 5G).

[0145] In some embodiments, the terminals disclosed herein operate in the FR1 or FR2 frequency bands. Optionally, in the low-frequency FR1 band, the available spectrum is more fragmented and the available bandwidth is generally narrower, making it more suitable for inter-band multi-carrier operations. In the FR2 band and parts of the FR1 band, the available spectrum can be wider, making it more suitable for intra-band multi-carrier operations. To meet the needs of different application scenarios and ensure the efficient use of both fragmented and wide spectrum, enhancements to uplink multi-carrier are necessary.

[0146] In some embodiments, the terminal in the present disclosure supports up to two uplink antennas, meaning that the terminal can operate in up to two frequency bands. Alternatively, the terminal can be configured with more than two uplink frequency bands, thereby supporting two uplink antennas switching between more than two uplink frequency bands. For example, the terminal switches from frequency bands 1 and 2 to frequency bands 3 and 4. Another example is the terminal switching from both frequency bands 1 and 2 to frequency band 3. Another example is the terminal switching from frequency bands 1 and 2 to frequency bands 3 and 4, and so on.

[0147] In some embodiments, the present disclosure proposes two frequency band types. Optionally, the two types include switch-from band and switch-to band. The switch-from band indicates the band to which the initial transmission is directed, while the switch-to band indicates the band to which the next transmission is directed.

[0148] In some embodiments, the present disclosure proposes a solution to configure a priority list for all frequency bands. The higher the priority of the frequency band, the more priority it has in ensuring that transmission is not interrupted. In other words, when the terminal switches frequency bands, it should position the switching period on the low-priority frequency band.

[0149] Optionally, when the frequency band with the highest priority is the switch-to band, the switching period is located on the switch-from band; when the frequency band with the highest priority is the switch-from band, the switching period is located on the switch-to band.

[0150] In the related art, if the frequency band with the highest priority is both the switch-to band and the switch-from band, there will be a problem that the frequency band where the switching period is located cannot be determined according to the priority. In order to solve this problem, the present disclosure proposes the embodiment shown in Figure 2 to solve the above problem.

[0151] FIG2 is an interactive diagram of a frequency band switching method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a frequency band switching method, which includes:

[0152] Step S2101: The network device sends a first signaling.

[0153] In some embodiments, the terminal receives the first signaling. Alternatively, it can be understood that the terminal receives the first signaling sent by the network device.

[0154] In some embodiments, the network device sends a first signaling to the terminal.

[0155] In some embodiments, the first signaling is used to configure the first condition and a method for determining the frequency band in which the switching period is located. In some embodiments, the first signaling is used to configure the first condition and a method for determining the switching period. In some embodiments, the first signaling is used to configure the first condition and a method for determining the frequency band in which the duration required for frequency band switching is located. In some embodiments, the first signaling is used to configure a method for determining the frequency band in which the switching period is located when the first condition is met.

[0156] In some embodiments, the first condition refers to whether the priority relationship of the frequency bands included in the frequency band group and the type of the frequency bands meet the condition. In some embodiments, the first condition refers to the type of frequency bands of different priorities included in the frequency band group. In some embodiments, the first condition refers to the priorities of different types of frequency bands in the frequency band group.

[0157] In some embodiments, the frequency band group includes multiple frequency bands. For example, the frequency band group includes frequency band 1, frequency band 2, frequency band 3, and frequency band 4. In some embodiments, each frequency band corresponds to a priority.

[0158] In some embodiments, the name of the first condition in the present disclosure is not limited, and can be, for example, a switching condition, a judgment condition, a cycle condition, a positioning condition, etc.

[0159] In some embodiments, frequency band switching refers to switching a terminal from one frequency band to another. Alternatively, frequency band switching refers to switching a terminal's antenna from one frequency band to another. Optionally, frequency band switching refers to uplink frequency band switching. For another example, frequency band switching refers to uplink frequency band switching.

[0160] In some embodiments, the present disclosure does not limit the name of frequency band switching, which may be, for example, transmission link switching, send link switching, antenna switching, uplink switching, etc.

[0161] In some embodiments, the priority of a frequency band is indicated by a priority list. For example, the priority list includes frequency bands and their corresponding priorities. Each frequency band has a one-to-one correspondence with a priority. For another example, the priority list includes frequency bands, and the priority of the frequency bands decreases in descending order from top to bottom.

[0162] In some embodiments, the first signaling is RRC (Radio Resource Control), MAC CE (Media Access Control Control Element), DCI (Downlink Control Information), etc.

[0163] In some embodiments, the name of the first signaling is not limited, and can be, for example, a configuration instruction, a first message, etc.

[0164] In step S2102, the terminal determines a method based on the first condition and a frequency band in which the switching period is located.

[0165] In the embodiment of the present disclosure, when the terminal receives the first signaling, it can determine the first condition indicated and the frequency band of the switching period according to the first signaling.

[0166] Step S2103: The network device sends a second signaling.

[0167] In some embodiments, the terminal receives the second signaling. Alternatively, it can be understood that the terminal receives the second signaling sent by the network device.

[0168] In some embodiments, the network device sends second signaling to the terminal.

[0169] In some embodiments, the second signaling is used to instruct the terminal to switch frequency band. In some embodiments, the second signaling is used to instruct the terminal to switch from one frequency band to another frequency band.

[0170] Step S2104: The terminal determines, based on the second signaling, that the frequency band group meets the first condition, and determines that the switching period is located in the first frequency band or the second frequency band.

[0171] In some embodiments, the frequency band group includes multiple frequency bands. In some embodiments, the switching period is used to indicate the duration required for the terminal to perform frequency band switching. The first frequency band is different from the second frequency band.

[0172] In some embodiments, the name of the switching period is not limited, and can be, for example, switching duration, switching delay, etc.

[0173] In the embodiment of the present disclosure, if the terminal determines that the frequency band group meets the first condition, then the switching period is determined to be located in the first frequency band. Alternatively, if the terminal determines that the frequency band group meets the first condition, then the switching period is determined to be located in the second frequency band.

[0174] In some embodiments, the switching period being located in the first frequency band means that the switching period is within the duration of operation in the first frequency band. In other embodiments, the switching period being located in the first frequency band means that the switching period is within the duration of operation in the first frequency band.

[0175] In some embodiments, the switching period being located in the second frequency band means that the switching period is within the duration of operation in the second frequency band. In other embodiments, the switching period being located in the second frequency band means that the switching period is within the duration of operation in the second frequency band.

[0176] In some embodiments, the first frequency band and the second frequency band refer to frequency band types. Optionally, the first frequency band may also be referred to as a first frequency band type. The second frequency band may also be referred to as a second frequency band type.

[0177] In some embodiments, the first frequency band is a switch-to band and the second frequency band is a switch-from band; or, the first frequency band is a switch-from band and the second frequency band is a switch-to band.

[0178] In some embodiments, Switch-to band is used to indicate the band to which the next transmission is directed, and Switch-from band is used to indicate the band to which the initial transmission is directed.

[0179] The following describes how the terminal determines the frequency band where the switching period is located.

[0180] Type 1: In some embodiments, if it is determined that the switching period is located in the first frequency band, the first condition includes at least one of the following:

[0181] (1) Among the frequency bands that are switched in the frequency band group, the frequency band with the highest priority is the second frequency band.

[0182] In an embodiment of the present disclosure, the frequency band group includes multiple frequency bands, among which there are frequency bands where switching occurs and there are frequency bands where switching does not occur. The frequency bands where switching occurs in the frequency band group are determined. If the frequency band with the highest priority among the frequency bands where switching occurs is the second frequency band, the switching period is determined to be located in the first frequency band.

[0183] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 has not switched, and band 2 has switched to band 3. Therefore, band 2 and band 3 are the frequency bands that switch. The frequency band with the highest priority is determined from band 2 and band 3. If the frequency band is the second frequency band, the switching period is determined to be located in the first frequency band.

[0184] (2) The frequency bands included in the frequency band group are the frequency bands where switching occurs, and the frequency band with the highest priority in the frequency band group is the second frequency band.

[0185] In the embodiment of the present disclosure, the frequency band group includes frequency bands where switching occurs, and the frequency band with the highest priority among the frequency bands where switching occurs is the second frequency band, and the switching period is determined to be located in the first frequency band.

[0186] For example, if the frequency band group includes frequency band 2 and frequency band 3, frequency band 2 and frequency band 3 are the frequency bands where switching occurs, the frequency band with the highest priority is determined from frequency band 2 and frequency band 3. If the frequency band is the second frequency band, the switching period is determined to be located in the first frequency band.

[0187] It should be noted that both of the above scenarios are implemented when the frequency band with the highest priority in the frequency band group is both the first frequency band and the second frequency band. In some embodiments, the frequency band with the highest priority in the frequency band group is the frequency band that does not undergo switching. For example, if the frequency band group includes frequency bands 1, 2, 3, and 4, and frequency band 1 is the frequency band with the highest priority, and the terminal switches from frequency bands 1 and 2 to frequency bands 1 and 3, it can be seen that frequency band 1 does not undergo switching, and frequency band 2 switches to frequency band 3.

[0188] In some embodiments, if the terminal determines that the frequency band group satisfies at least one of the above-mentioned first conditions, it determines that the switching period is located in the first frequency band.

[0189] In some embodiments, the above scheme can be described as:

[0190] For uplink switching, the terminal determines the frequency band of the switching cycle position according to the configuration priority of the frequency band involved in the actual Tx switching in the uplink switching, where the priority of each frequency band is provided by the parameters of the higher layer.

[0191] - if the highest priority band is the switch-to band, then the switch-from band, or

[0192] - If the highest priority band is the switch-from band, then the switch-to band.

[0193] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands which involved the actual Tx switching in the uplink switch,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0194] -the switch-from band(s)if the highest priority band is a switch-to band,or

[0195] -the switch-to band(s)if the highest priority band is a switch-from band.)

[0196] In some embodiments, the above scheme can be described as:

[0197] For uplink handover, the terminal determines the frequency band where the handover period is located based on the configured frequency band priority, where the priority of each frequency band is provided by a higher layer parameter. The handover period is located at any position.

[0198] - If the highest priority band involved in the actual Tx switching in the uplink switch is the switch-to band, the switch-from band

[0199] - If the highest priority band involved in the actual Tx exchange in the upstream switch is the switch-from band, the switch-to band.

[0200] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0201] -the switch-from band(s)if the highest priority band which involved the actual Tx switching in the uplink switch is a switch-to band,or

[0202] -the switch-to band(s)if the highest priority band which involved the actual Tx switching in the uplink switch is a switch-from band.)

[0203] Second: In some embodiments, determining that the switching period is located in the second frequency band, the first condition includes at least one of the following:

[0204] (1) Among the frequency bands that are switched in the frequency band group, the frequency band with the highest priority is the first frequency band.

[0205] In an embodiment of the present disclosure, the frequency band group includes multiple frequency bands, among which there are frequency bands where switching occurs and there are frequency bands where switching does not occur. The frequency bands where switching occurs in the frequency band group are determined. If the frequency band with the highest priority among the frequency bands where switching occurs is the first frequency band, the switching period is determined to be located in the second frequency band.

[0206] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 has not switched, and band 2 has switched to band 3. Therefore, band 2 and band 3 are the frequency bands that switch. The frequency band with the highest priority is determined from band 2 and band 3. If the frequency band is the first frequency band, the switching period is determined to be located in the second frequency band.

[0207] (2) The frequency bands included in the frequency band group are the frequency bands where switching occurs, and the frequency band with the highest priority in the frequency band group is the first frequency band.

[0208] In the embodiment of the present disclosure, the frequency band group includes frequency bands where switching occurs, and the frequency band with the highest priority among the frequency bands where switching occurs is the first frequency band, and the switching period is determined to be located in the second frequency band.

[0209] For example, if the frequency band group includes frequency band 2 and frequency band 3, frequency band 2 and frequency band 3 are the frequency bands where switching occurs, the frequency band with the highest priority is determined from frequency band 2 and frequency band 3. If the frequency band is the first frequency band, the switching period is determined to be located in the second frequency band.

[0210] It should be noted that both of the above scenarios are implemented when the frequency band with the highest priority in the frequency band group is both the first frequency band and the second frequency band. In some embodiments, the frequency band with the highest priority in the frequency band group is the frequency band that does not undergo switching. For example, if the frequency band group includes frequency bands 1, 2, 3, and 4, and frequency band 1 is the frequency band with the highest priority, and the terminal switches from frequency bands 1 and 2 to frequency bands 1 and 3, it can be seen that frequency band 1 does not undergo switching, and frequency band 2 switches to frequency band 3.

[0211] In some embodiments, if the terminal determines that the frequency band group satisfies at least one of the above-mentioned first conditions, it determines that the switching period is located in the second frequency band.

[0212] In some embodiments, the above scheme can be described as:

[0213] For uplink switching, the terminal determines the frequency band of the switching cycle position according to the configuration priority of the frequency band involved in the actual Tx switching in the uplink switching, where the priority of each frequency band is provided by the parameters of the higher layer.

[0214] - if the highest priority band is the switch-to band, then the switch-from band, or

[0215] - If the highest priority band is the switch-from band, then the switch-to band.

[0216] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands which involved the actual Tx switching in the uplink switch,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0217] -the switch-from band(s)if the highest priority band is a switch-to band,or

[0218] -the switch-to band(s)if the highest priority band is a switch-from band.)

[0219] In some embodiments, the above scheme can be described as:

[0220] For uplink handover, the terminal determines the frequency band where the handover period is located based on the configured frequency band priority, where the priority of each frequency band is provided by a higher layer parameter. The handover period is located at any position.

[0221] - If the highest priority band involved in the actual Tx switching in the uplink switch is the switch-to band, the switch-from band

[0222] - If the highest priority band involved in the actual Tx exchange in the upstream switch is the switch-from band, the switch-to band.

[0223] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0224] -the switch-from band(s)if the highest priority band which involved the actual Tx switching in the uplink switch is a switch-to band,or

[0225] -the switch-to band(s)if the highest priority band which involved the actual Tx switching in the uplink switch is a switch-from band.)

[0226] In some embodiments, the first condition includes at least one of the following:

[0227] (1) The frequency band with the highest priority in the frequency band group is both the first frequency band and the second frequency band.

[0228] In the disclosed embodiment, if the frequency band with the highest priority in the frequency band group is both the first frequency band and the second frequency band, the switching period is determined to be located in the first frequency band. Alternatively, if the frequency band with the highest priority in the frequency band group is both the first frequency band and the second frequency band, the switching period is determined to be located in the second frequency band.

[0229] For example, if the frequency band group includes frequency band 1, frequency band 2, frequency band 3 and frequency band 4, the frequency band with the highest priority is determined from frequency band 1, frequency band 2, frequency band 3 and frequency band 4. If the frequency band is both the first frequency band and the second frequency band, the switching period is determined to be positioned in the first frequency band or the second frequency band.

[0230] (2) Among the frequency bands that are switched in the frequency band group, the frequency band with the highest priority is both the first frequency band and the second frequency band.

[0231] In the disclosed embodiment, if the frequency band with the highest priority among the frequency bands to be switched in the frequency band group is both the first frequency band and the second frequency band, the switching period is determined to be located in the first frequency band. Alternatively, if the frequency band with the highest priority among the frequency bands to be switched in the frequency band group is both the first frequency band and the second frequency band, the switching period is determined to be located in the second frequency band.

[0232] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 did not switch, and band 2 switched to band 3. Therefore, band 2 and band 3 are the frequency bands that switched. The frequency band with the highest priority is determined from band 2 and band 3. If the frequency band is both the first frequency band and the second frequency band, the switching period is determined to be located in the first frequency band or the second frequency band.

[0233] (3) Among the frequency bands involved in the switching in the frequency band group, the frequency band with the highest priority is both the first frequency band and the second frequency band.

[0234] In the embodiment of the present disclosure, if the frequency band with the highest priority among the frequency bands involved in switching in the frequency band group is both the first frequency band and the second frequency band, then the switching period is determined to be located in the first frequency band. Alternatively, if the frequency band with the highest priority among the frequency bands involved in switching in the frequency band group is both the first frequency band and the second frequency band, then the switching period is determined to be located in the second frequency band.

[0235] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 did not switch, and band 2 switched to band 3. Therefore, band 1, band 2 and band 3 all involve switching. The frequency band with the highest priority is determined from band 1, band 2 and band 3. If the frequency band is both the first frequency band and the second frequency band, the switching period is determined to be located in the first frequency band or the second frequency band.

[0236] In some embodiments, if the terminal determines that the frequency band group satisfies at least one of the above-mentioned first conditions, it determines that the switching period is located in the first frequency band or the second frequency band.

[0237] In some embodiments, the above scheme can be described as:

[0238] For uplink handover, the terminal determines the frequency band where the handover period is located based on the configured frequency band priority, where the priority of each frequency band is provided by a higher layer parameter. The handover period is located at any position.

[0239] - if the highest priority band involved in the switch is the switch-to band, then the switch-from band, or

[0240] - If the highest priority band involved in the switch is the switch-from band, then the switch-to band.

[0241] If the switch-from band and the switch-to band involved in the switching are both the highest priority bands, the switching period is located on the switch-from band.

[0242] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0243] -the switch-from band(s)if the highest priority band involved in the switching is a switch-to band,or

[0244] -the switch-to band(s)if the highest priority band involved in the switching is a switch-from band.

[0245] If the highest priority band is involved in both the switching switched-from band(s)and switch-to band(s), the switch is located on the switch-from band(s).)

[0246] In some embodiments, the above scheme can be described as:

[0247] For uplink handover, the terminal determines the frequency band where the handover period is located based on the configured frequency band priority, where the priority of each frequency band is provided by a higher layer parameter. The handover period is located at any position.

[0248] - if the highest priority band involved in the switch is the switch-to band, then the switch-from band, or

[0249] - If the highest priority band involved in the switch is the switch-from band, then the switch-to band.

[0250] If the switch-from band and the switch-to band involved in the switch are both the highest priority bands, the switch period is located on the switch-to band.

[0251] (For an uplink switch the UE determines the band of the switching period location based on the configured priority of the bands,where the priority per band is provided by the higher layer parameter.The switch is located on either

[0252] -the switch-from band(s)if the highest priority band involved in the switching is a switch-to band,or

[0253] -the switch-to band(s)if the highest priority band involved in the switching is a switch-from band.]

[0254] If the highest priority band is involved in both the switching switched-from band(s)and switch-to band(s), the switch is located on the switch-to band(s).)

[0255] Fourth: In some embodiments, determining that the switching period is located in the first frequency band, the first condition includes at least one of the following:

[0256] (1) The frequency band with the lowest priority in the frequency band group is the first frequency band.

[0257] In the embodiment of the present disclosure, if the frequency band with the lowest priority in the frequency band group is the first frequency band, the switching period is determined to be positioned in the first frequency band.

[0258] For example, if the frequency band group includes frequency band 1, frequency band 2, frequency band 3 and frequency band 4, the frequency band with the lowest priority is determined from frequency band 1, frequency band 2, frequency band 3 and frequency band 4. If the frequency band is the first frequency band, the switching period is determined to be positioned in the first frequency band.

[0259] (2) Among the frequency bands that are switched in the frequency band group, the frequency band with the lowest priority is the first frequency band.

[0260] In the embodiment of the present disclosure, if the frequency band with the lowest priority among the frequency bands to be switched in the frequency band group is the first frequency band, the switching period is determined to be located in the first frequency band.

[0261] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 has not switched, and band 2 has switched to band 3. Therefore, band 2 and band 3 are the frequency bands that switch. Determine the frequency band with the lowest priority from band 2 and band 3. If the frequency band is the first frequency band, determine that the switching period is located in the first frequency band.

[0262] (3) Among the frequency bands involved in switching in the frequency band group, the frequency band with the lowest priority is the first frequency band.

[0263] In the embodiment of the present disclosure, if the frequency band with the lowest priority among the frequency bands involved in the switching in the frequency band group is the first frequency band, then the switching period is determined to be located in the first frequency band.

[0264] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 does not switch, and band 2 switches to band 3. Therefore, band 1, band 2 and band 3 all involve switching. Determine the frequency band with the lowest priority from band 1, band 2 and band 3. If the frequency band is the first frequency band, determine that the switching period is located in the first frequency band.

[0265] In some embodiments, if the terminal determines that the frequency band group satisfies at least one of the above-mentioned first conditions, it determines that the switching period is located in the first frequency band or the second frequency band.

[0266] Fifth: In some embodiments, the switching period is determined to be located in the second frequency band, and the first condition includes at least one of the following:

[0267] (1) The frequency band with the lowest priority in the frequency band group is the second frequency band.

[0268] In the embodiment of the present disclosure, if the frequency band with the lowest priority in the frequency band group is the second frequency band, the switching period is determined to be positioned in the second frequency band.

[0269] For example, if the frequency band group includes frequency band 1, frequency band 2, frequency band 3 and frequency band 4, determine the frequency band with the lowest priority from frequency band 1, frequency band 2, frequency band 3 and frequency band 4. If the frequency band is the second frequency band, determine that the switching period is positioned in the second frequency band.

[0270] (2) Among the frequency bands that are switched in the frequency band group, the frequency band with the lowest priority is the second frequency band.

[0271] In the embodiment of the present disclosure, if the frequency band with the lowest priority among the frequency bands to be switched in the frequency band group is the second frequency band, the switching period is determined to be located in the second frequency band.

[0272] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 has not switched, and band 2 has switched to band 3. Therefore, band 2 and band 3 are the frequency bands that have switched. The frequency band with the lowest priority is determined from band 2 and band 3. If the frequency band is the second frequency band, the switching period is determined to be located in the second frequency band.

[0273] (3) Among the frequency bands involved in switching in the frequency band group, the frequency band with the lowest priority is the second frequency band.

[0274] In the embodiment of the present disclosure, if the frequency band with the lowest priority among the frequency bands involved in the switching in the frequency band group is the second frequency band, then the switching period is determined to be located in the second frequency band.

[0275] For example, if the frequency band group includes band 1, band 2, band 3 and band 4, and the terminal switches from band 1 and band 2 to band 1 and band 3, it can be seen that band 1 does not switch, and band 2 switches to band 3. Therefore, band 1, band 2 and band 3 all involve switching. The frequency band with the lowest priority is determined from band 1, band 2 and band 3.
