[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0033] Figure 1 This is a schematic flowchart illustrating an uplink transmission handover method according to an embodiment of the present disclosure. The uplink transmission handover method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0034] like Figure 1 As shown, the uplink transmission switching method may include the following steps:

[0035] In step S101, the uplink frequency band group for uplink transmission switching (UL TX switching) is determined;

[0036] In step S102, uplink transmission switching is performed between the uplink frequency bands (specifically, the carriers corresponding to the uplink frequency bands) included in the uplink frequency band group. The terminal can support dual transmission links (2TX) in both the uplink frequency band before and after the switching.

[0037] In one embodiment, the scenarios in which the terminal performs uplink transmission switching include, but are not limited to, dual connectivity (e.g., EN-DC), carrier aggregation (e.g., inter-band carrier aggregation, or supplementary uplink, SUL).

[0038] For example, consider a terminal switching uplink transmission from the first uplink frequency band to the second uplink frequency band.

[0039] In a dual-connectivity scenario, when a terminal performs uplink transmission handover, it can switch from the primary cell group carrier to the secondary cell group carrier. The primary cell group carrier belongs to the first uplink frequency band, and the secondary cell group carrier belongs to the second uplink frequency band.

[0040] In carrier aggregation scenarios, such as the aggregation of carriers in band #1 and band #2, the terminal can switch uplink transmission from the carrier in band #1 to the carrier in band #2. Here, the first uplink frequency band can be band #1 and the second uplink frequency band can be band #2.

[0041] In the supplementary uplink scenario, the terminal can switch uplink transmission from the normal uplink carrier to the supplementary uplink carrier. The normal uplink carrier belongs to the first uplink frequency band, and the supplementary uplink carrier belongs to the second uplink frequency band.

[0042] In one embodiment, the strategy for the terminal to perform uplink transmission handover includes, but is not limited to, the following two:

[0043] The terminal does not support uplink transmission in two uplink frequency bands simultaneously, i.e., SwitchedUL;

[0044] The terminal supports uplink transmission in two uplink frequency bands simultaneously, also known as DualUL.

[0045] As for which strategy the terminal uses, it can be indicated by the network device, for example, the network can indicate it through Radio Resource Control (RRC) signaling.

[0046] In one embodiment, when a terminal performs uplink transmission handover, for the three application scenarios mentioned above, only the handover between two uplink frequency bands is considered. In this case, the terminal only needs to prepare for communication on these two uplink frequency bands. However, when the terminal needs to support uplink transmission handover between more than two frequency bands, the terminal needs to prepare for communication on more than two uplink frequency bands, which increases the complexity of uplink transmission handover. Therefore, it is necessary to consider how to reduce the complexity of uplink transmission handover.

[0047] According to embodiments of this disclosure, a terminal can determine an uplink frequency band group for uplink transmission switching, wherein the uplink frequency band group may include one or more frequency bands, and the number of frequency bands included in the uplink frequency band group may be less than the number of uplink frequency bands supported by the terminal, or less than the number of uplink frequency bands corresponding to the carriers configured by the network device for uplink transmission switching for the terminal.

[0048] For example, an uplink band group can contain two uplink bands, while the number of uplink bands supported by the terminal, or the number of uplink bands corresponding to the carriers configured by the network device for uplink transmission switching, can be three or four. When an uplink band group contains two uplink bands, it can also be called an uplink band pair (UL band pair).

[0049] Therefore, when a terminal performs uplink transmission handover between uplink frequency bands included in the uplink frequency band group, it will only switch from one uplink frequency band in the uplink frequency band group to another frequency band in the uplink frequency band group, and will not switch to an uplink frequency band outside the uplink frequency band group. Accordingly, the terminal only needs to prepare for communication on the uplink frequency bands within the uplink frequency band group (e.g., software, hardware, handover process preparation), and does not need to prepare for communication on uplink frequency bands outside the uplink frequency band group, thereby reducing the complexity of uplink transmission handover for the terminal.

[0050] It should be noted that the terminal does not need to prepare for communication on uplink bands outside the currently used uplink band group. This means that during the effective period of the currently used uplink band group, no preparation is needed for communication on uplink bands outside the current uplink band group. If, after the effective period, it needs to switch to uplink transmission handover between uplink bands included in other uplink band groups, then preparation for communication on uplink bands included in other uplink band groups will be required after the effective period. However, this still reduces the complexity of uplink transmission handover for the terminal during the effective period. Furthermore, the uplink bands included in different uplink band groups can be completely different or partially the same. The terminal can support the uplink transmission handover mechanism in Rel-17 for uplink transmission handover.

[0051] Figure 2 This is a schematic flowchart illustrating another uplink transmission switching method according to embodiments of the present disclosure. Figure 2 As shown, determining the uplink frequency band group for uplink transmission switching includes:

[0052] In step S201, the time-domain pattern of the uplink frequency band group is determined;

[0053] In step S202, the uplink frequency band group corresponding to the time domain resource where the uplink transmission switching is located is determined according to the time domain pattern.

[0054] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, uplink transmission handover can be performed based on different uplink frequency band groups on different time domain resources. The correspondence between the uplink frequency band group on which the uplink transmission handover is based and the time domain resources can be represented by a time domain pattern of the uplink frequency band group. This time domain pattern can be protocol-defined or indicated by the network device.

[0055] The terminal can determine the time domain resources where the uplink transmission handover is located (i.e., the time domain resources when uplink transmission handover is required), and then determine the uplink frequency band group corresponding to the time domain resources according to the time domain pattern. Thus, the uplink transmission handover is performed based on the determined uplink frequency band group, that is, the uplink transmission handover is performed between the uplink frequency bands included in the determined uplink frequency band group.

[0056] For example, the network side configures 4 carriers for the terminal for uplink transmission switching. The 4 carriers are located in different uplink frequency bands, and the uplink frequency band group candidate set configured by the network device for the terminal contains P uplink frequency band groups. The uplink frequency band group on which the terminal performs uplink switching belongs to the uplink frequency band group candidate set.

[0057] For example, if P=2, uplink frequency band group #1 contains two frequency bands, band#1 and band#2, with carrier#1 located within band#1 and carrier#2 located within band#2. Then the carriers corresponding to the first uplink frequency band group are {carrier#1, carrier#2}. Uplink frequency band group #2 contains two frequency bands, band#3 and band#4, with carrier#3 located within band#3 and carrier#4 located within band#4. Then the carriers corresponding to the second uplink frequency band group are {carrier#3, carrier#4}.

[0058] The terminal can determine the correspondence between time-domain resources (e.g., time slots) and uplink frequency bands based on the following formula:

[0059] mod(slotindex / m,P)=pairindex;

[0060] Where mod represents the remainder, slotindex represents the slot index, m represents the effective period of the uplink frequency band group (the unit can be a time slot), P represents the number of uplink frequency band groups in the candidate set of uplink frequency band groups, for example, 2 in this embodiment, and pairindex represents the index of the uplink frequency band group, for example, the index of uplink frequency band group #1 is 1 and the index of uplink frequency band group #2 is 2.

[0061] When mod(slotindex / m,P) = 1, that is, pairindex = 1, it can be determined that the uplink frequency band group in which the uplink transmission handover occurs is uplink frequency band group #1, that is, the terminal is on the carriers {carrier#1, carrier#2} corresponding to uplink frequency band group #1.

[0062] Uplink transmission switching is performed during this process;

[0063] When mod(slotindex / m,P) = 2, that is, pairindex = 2, it can be determined that the uplink frequency band group in which the uplink transmission handover occurs is uplink frequency band group #2, that is, the terminal is on the carriers {carrier#3, carrier#4} corresponding to uplink frequency band group #2.

[0064] Uplink transmission switching is performed during this process.

[0065] Figure 3 This is a schematic diagram of a time-domain pattern according to an embodiment of the present disclosure.

[0066] like Figure 3 As shown, with m=5 and P=2, the time domain range is from slot#0 to slot#14.

[0067] Substituting slots #0 to #4 into the above formula, we can obtain the corresponding pairindex as 1. That is, in slots #0 to #4, uplink transmission switching is performed using the carriers {carrier #1, carrier #2} corresponding to uplink frequency band group #1.

[0068] Substituting slots #5 to #9 into the above formula, we can obtain the corresponding pairindex as 2. That is, in slots #5 to #9, the uplink transmission switching is performed using the carriers {carrier #3, carrier #4} corresponding to uplink frequency band group #2.

[0069] Substituting into the above formula, we can obtain the corresponding pairindex as 1 for slots #10 to #14. That is, in slots #10 to #14, the uplink transmission switching is performed using the carriers {carrier #1, carrier #2} corresponding to uplink frequency band group #1.

[0070] By analogy, the uplink frequency band group corresponding to each time domain resource can be determined, and then uplink transmission switching can be performed between the carriers corresponding to the uplink frequency bands contained in the determined uplink frequency band group.

[0071] The following examples illustrate how the uplink frequency band group on which the uplink transmission switching is based changes.

[0072] Figure 4 This is a schematic flowchart illustrating yet another uplink transmission switching method according to embodiments of the present disclosure. Figure 4 As shown, the method further includes:

[0073] In step S401, it is determined that the effective period of the first uplink frequency band group in which the uplink transmission switch is currently taking place has ended, and the uplink frequency band indicated by the network device for uplink transmission does not belong to the first uplink frequency band group, so the switch is made to the second uplink frequency band group for uplink transmission switch.

[0074] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, the terminal can determine whether the effective period of the first uplink frequency band group in which the uplink transmission handover is currently taking place has ended. If it has ended, then the uplink frequency band group in which the uplink transmission handover is taking place can be changed. However, changing the uplink frequency band group in which the uplink transmission handover is taking place requires changing some internal logic of the terminal, which incurs certain overhead.

[0075] Therefore, it can be further determined whether the uplink frequency band indicated by the network device for uplink transmission belongs to the first uplink frequency band group.

[0076] If the uplink frequency band indicated by the network device for uplink transmission still belongs to the first uplink frequency band group, then uplink transmission switching within the first uplink frequency band group can still switch to the uplink frequency band indicated by the network device for uplink transmission, thus meeting communication requirements. Therefore, in this case, it is not necessary to change the uplink frequency band group in which the uplink transmission switching takes place, that is, the uplink transmission switching is still performed among the uplink frequency bands included in the first uplink frequency band group, which helps to reduce terminal power consumption.

[0077] If the uplink frequency band indicated by the network device for uplink transmission still does not belong to the first uplink frequency band group, then uplink transmission switching within the first uplink frequency band group cannot switch to the uplink frequency band indicated by the network device, thus failing to meet communication requirements. Therefore, in this case, the uplink frequency band group in which the uplink transmission switching takes place can be changed, for example, switching to the second uplink frequency band group, and uplink transmission switching can be performed between the uplink frequency bands included in the second uplink frequency band group in order to meet communication needs.

[0078] Figure 5 This is a schematic diagram illustrating an embodiment of the present disclosure of a change in the uplink frequency band group where the uplink transmission switching occurs.

[0079] like Figure 5 As shown, the uplink frequency band group is active for 5 time slots. The first uplink frequency band group where the uplink transmission switching is currently taking place includes uplink frequency bands band#1 and band#2.

[0080] After the effective period of the first uplink frequency band group (e.g., slots #0 to #4) ends, if the uplink transmission resource indicated by the network device in slot #5 is not in band #1 or band #2, but in band #3, then the terminal can change the uplink frequency band group after slot #4, for example, switch to the second uplink frequency band group for uplink transmission switching. The second uplink frequency band group can include band #3 and band #4. Accordingly, it can be ensured that the terminal can successfully complete uplink transmission in band #3 based on the network device configuration.

[0081] After the effective period of the second uplink frequency band group (e.g., slot#5 to slot#9) ends, if the uplink transmission resources indicated by the network device in slot#10 are within band#4, that is, still within the uplink frequency band corresponding to the second uplink frequency band group, then the terminal can continue to perform uplink transmission switching in the second uplink frequency band group.

[0082] Figure 6 This is a schematic flowchart illustrating yet another uplink transmission switching method according to embodiments of the present disclosure. Figure 6 As shown, the method further includes:

[0083] In step S601, it is determined that the timer corresponding to the first uplink frequency band group where the uplink transmission switch is currently taking place has timed out, and the switch is made to the second uplink frequency band group for uplink transmission switch.

[0084] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, each uplink frequency band group can correspond to a timer. If the timer corresponding to the first uplink frequency band group where the current uplink transmission handover is taking place times out, the uplink frequency band group on which the uplink transmission handover is based can be changed, for example, switching to the second uplink frequency band group for uplink transmission handover.

[0085] In one embodiment, the timer starts when uplink transmission within the uplink band included in the first uplink band group ends and restarts when uplink transmission occurs within the uplink band included in the first uplink band group. This avoids the timer timing out when uplink transmission occurs within the uplink band included in the first uplink band group, thus preventing a change in the uplink band group on which the uplink transmission switching is based and ensuring that uplink transmissions within the uplink band included in the first uplink band group can be successfully completed.

[0086] Figure 7 This is a schematic diagram illustrating another change in the uplink frequency band group where the uplink transmission switching occurs, according to an embodiment of the present disclosure.

[0087] like Figure 7As shown, taking the first uplink frequency band group containing band #1 and band #2, and the second uplink frequency band group containing band #3 and band #4 as an example.

[0088] The timeout durations of the timers corresponding to different uplink frequency bands can be the same or different. For the sake of simplicity, we will take the example where the timeout durations of the timers corresponding to the first and second uplink frequency bands are the same. For example, if the timeout duration of the timer is 100 milliseconds, and the subcarrier spacing (SCS) is 15 Hz, 100 milliseconds is equivalent to 100 time slots.

[0089] exist Figure 7 In the current scenario, the terminal is switching uplink transmission in the first frequency band group. The uplink transmission in band#1 memory ends at slot#0, so the timer corresponding to the first frequency band group can start counting in slot#1. Since another uplink transmission occurs in slot#4 within band#2 and ends in slot#4, the timer restarts in slot#5, that is, it restarts counting.

[0090] If no uplink transmission occurs within band #1 or band #2 up to slot #104, the timer expires, and the terminal can switch to the second uplink frequency band group for uplink transmission switching.

[0091] Figure 8 This is a schematic flowchart illustrating yet another uplink transmission switching method according to embodiments of the present disclosure. Figure 8 As shown, the method further includes:

[0092] In step S801, if the service meets the preset conditions, the uplink transmission switching is performed from the first uplink frequency band group where the uplink transmission switching is currently taking place to the second uplink frequency band group.

[0093] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission switching can be changed. For example, the terminal can analyze the service corresponding to the communication, and if the service meets preset conditions, it can switch from the first uplink frequency band group where the uplink transmission switching is currently taking place to the second uplink frequency band group to ensure that the service requirements are met.

[0094] In one embodiment, the preset condition includes at least one of the following:

[0095] The business arrival rate is lower than the arrival rate value;

[0096] The business priority is higher or lower than the priority threshold;

[0097] The Quality of Service (QoS) is below the QoS threshold.

[0098] For example, if the service arrival rate is lower than the arrival rate value when performing uplink transmission switching in the first uplink frequency band group, it is difficult to meet the service's arrival rate requirements. Therefore, the uplink transmission can be switched to the second uplink frequency band group to meet the service's arrival rate requirements.

[0099] For example, if the service quality falls below the service quality threshold during uplink transmission handover in the first uplink frequency band group, it is difficult to meet the service quality requirements. Therefore, the uplink transmission handover can be performed in the second uplink frequency band group to meet the service quality requirements.

[0100] For example, if the uplink transmission handover is performed in the first uplink frequency band group and the priority of the service to be performed is higher than the priority threshold, then when it is determined that the service is performed in the uplink frequency band corresponding to the first uplink frequency band group, the needs of the relatively high priority (higher than the priority threshold) service cannot be met. In this case, it is possible to choose to switch to the second uplink frequency band group for uplink transmission handover in order to meet the needs of the relatively high priority service.

[0101] For example, if the uplink transmission handover is performed in the first uplink frequency band group and the priority of the service to be performed is lower than the priority threshold, then when the uplink frequency band in the first uplink frequency band group is used for services with relatively higher priority (above the priority threshold), then it is possible to choose to switch to the second uplink frequency band group for uplink transmission handover, so as to avoid services with relatively lower priority (below the priority threshold) occupying the uplink frequency band in the first uplink frequency band group.

[0102] In one embodiment, the method further includes: determining an uplink frequency band group candidate set, wherein the first uplink frequency band group and the second uplink frequency band group belong to the uplink frequency band group candidate set.

[0103] In one embodiment, the method includes: determining an initial uplink frequency band group according to instructions or protocol agreements of the network device.

[0104] When a terminal initially performs an uplink transmission switch, it can switch uplink transmission between uplink frequency bands included in the initial uplink frequency band group. The initial uplink frequency band group can be indicated by the network device or determined based on the protocol agreement.

[0105] When a terminal changes the uplink frequency band group on which uplink transmission handover is based, it can select the uplink frequency band group to which it needs to switch from the candidate set of uplink frequency band groups. For example, when performing uplink transmission handover between uplink frequency bands included in the first uplink frequency band group, if it needs to change the uplink frequency band group on which the uplink transmission handover is based, it can select the second uplink frequency band group from the candidate set of uplink frequency band groups, and then switch to the second uplink frequency band group for uplink transmission handover, that is, perform uplink transmission handover between uplink frequency bands included in the second uplink frequency band group. The candidate set of uplink frequency band groups can be indicated by the network device or determined based on protocol agreements.

[0106] Figure 9 This is a schematic flowchart illustrating an uplink transmission control method according to an embodiment of the present disclosure. The uplink transmission control method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0107] like Figure 9 As shown, the uplink transmission control method may include the following steps:

[0108] In step S901, the uplink frequency band group for which the terminal performs uplink transmission switching is determined;

[0109] In step S902, the terminal is not scheduled or configured to perform uplink transmission in the uplink frequency band outside the uplink frequency band group (or it can be described as the terminal being scheduled or configured to perform uplink transmission only in the uplink frequency band within the uplink frequency band group).

[0110] In one embodiment, the scenarios in which the terminal performs uplink transmission switching include, but are not limited to, dual connectivity (e.g., EN-DC), carrier aggregation (e.g., in-band carrier aggregation, Inter-band CA), and supplementary uplink (SUL) scenarios.

[0111] For example, consider a terminal switching uplink transmission from the first uplink frequency band to the second uplink frequency band.

[0112] In a dual-connectivity scenario, when a terminal performs uplink transmission handover, it can switch from the primary cell group carrier to the secondary cell group carrier. The primary cell group carrier belongs to the first uplink frequency band, and the secondary cell group carrier belongs to the second uplink frequency band.

[0113] In carrier aggregation scenarios, such as the aggregation of carriers in band #1 and band #2, the terminal can switch uplink transmission from the carrier in band #1 to the carrier in band #2. Here, the first uplink frequency band can be band #1 and the second uplink frequency band can be band #2.

[0114] In the supplementary uplink scenario, the terminal can switch uplink transmission from the normal uplink carrier to the supplementary uplink carrier. The normal uplink carrier belongs to the first uplink frequency band, and the supplementary uplink carrier belongs to the second uplink frequency band.

[0115] In one embodiment, the strategy for the terminal to perform uplink transmission handover includes, but is not limited to, the following two:

[0116] The terminal does not support uplink transmission in two uplink frequency bands simultaneously, i.e., SwitchedUL;

[0117] The terminal supports uplink transmission in two uplink frequency bands simultaneously, also known as DualUL.

[0118] As for which strategy the terminal uses, it can be indicated by the network equipment, for example, the network can indicate it through Radio Resource Control (RRC) signaling.

[0119] In one embodiment, when a terminal performs uplink transmission handover, for the three application scenarios mentioned above, only the handover between two uplink frequency bands is considered. In this case, the terminal only needs to prepare for communication on these two uplink frequency bands. However, when the terminal needs to support uplink transmission handover between more than two frequency bands, the terminal needs to prepare for communication on more than two uplink frequency bands, which increases the complexity of uplink transmission handover. Therefore, it is necessary to consider how to reduce the complexity of uplink transmission handover.

[0120] According to embodiments of this disclosure, a network device can determine the uplink frequency band group for uplink transmission switching of a terminal. The uplink frequency band group may include one or more frequency bands, and the number of frequency bands included in the uplink frequency band group may be less than the number of uplink frequency bands supported by the terminal, or less than the number of uplink frequency bands corresponding to the carriers configured by the network device for uplink transmission switching of the terminal.

[0121] For example, an uplink frequency band group can contain two uplink frequency bands, while the number of uplink frequency bands supported by the terminal, or the number of uplink frequency bands corresponding to the carriers configured by the network device for uplink transmission switching, can be three or four. When an uplink frequency band group contains two uplink frequency bands, it can also be called an uplink frequency band pair.

[0122] Therefore, network devices only schedule or configure the terminal for uplink transmission within the uplink frequency bands of the uplink frequency band group, and do not schedule or configure the terminal for uplink transmission in uplink frequency bands outside the uplink frequency band group. Accordingly, the terminal can ensure smooth communication by only switching uplink transmission between uplink frequency bands included in the uplink frequency band group, thus satisfying the scheduling or configuration requirements of the network device. Based on this, the terminal only needs to switch from one uplink frequency band in the uplink frequency band group to another frequency band in the uplink frequency band group, without switching to an uplink frequency band outside the uplink frequency band group. Therefore, the terminal only needs to prepare for communication on the uplink frequency bands within the uplink frequency band group (e.g., software, hardware, handover process preparation), and does not need to prepare for communication on uplink frequency bands outside the uplink frequency band group, thereby reducing the complexity of uplink transmission handover for the terminal.

[0123] In one embodiment, determining the uplink frequency band group for uplink transmission handover includes: determining the time domain pattern of the uplink frequency band group; and determining the uplink frequency band group corresponding to the time domain resource where the terminal performs uplink transmission handover based on the time domain pattern.

[0124] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, uplink transmission handover can be performed based on different uplink frequency band groups on different time domain resources. The correspondence between the uplink frequency band group on which the uplink transmission handover is based and the time domain resources can be represented by a time domain pattern of the uplink frequency band group. This time domain pattern can be protocol-defined or indicated by the network device.

[0125] Network devices can determine the time-domain resources in which the terminal performs uplink transmission switching (i.e., the time-domain resources when uplink transmission switching is required), and then determine the uplink frequency band group corresponding to the time-domain resources based on the time-domain pattern. In other words, it can determine that the terminal performs uplink transmission switching between the uplink frequency bands included in the determined uplink frequency band group, so that the terminal is not scheduled or configured to perform uplink transmission in the uplink frequency band outside the determined uplink frequency band group.

[0126] For example, the network side configures 4 carriers for the terminal for uplink transmission switching. The 4 carriers are located in different uplink frequency bands, and the uplink frequency band group candidate set configured by the network device for the terminal contains P uplink frequency band groups. The uplink frequency band group on which the terminal performs uplink switching belongs to the uplink frequency band group candidate set.

[0127] For example, if P=2, uplink frequency band group #1 contains two frequency bands, band#1 and band#2, with carrier#1 located within band#1 and carrier#2 located within band#2. Then the carriers corresponding to the first uplink frequency band group are {carrier#1, carrier#2}. Uplink frequency band group #2 contains two frequency bands, band#3 and band#4, with carrier#3 located within band#3 and carrier#4 located within band#4. Then the carriers corresponding to the second uplink frequency band group are {carrier#3, carrier#4}.

[0128] Network devices can determine the correspondence between time-domain resources (e.g., time slots) and uplink frequency bands based on the following formula:

[0129] mod(slotindex / m,P)=pairindex;

[0130] Where mod represents the remainder, slotindex represents the slot index, m represents the effective period of the uplink frequency band group (the unit can be a time slot), P represents the number of uplink frequency band groups in the candidate set of uplink frequency band groups, for example, 2 in this embodiment, and pairindex represents the index of the uplink frequency band group, for example, the index of uplink frequency band group #1 is 1 and the index of uplink frequency band group #2 is 2.

[0131] When mod(slotindex / m,P) = 1, that is, pairindex = 1, it can be determined that the uplink frequency band group in which the uplink transmission handover occurs is uplink frequency band group #1, that is, the terminal is on the carriers {carrier#1, carrier#2} corresponding to uplink frequency band group #1.

[0132] Uplink transmission switching is performed during this process, so that the network device does not schedule or configure the terminal to perform uplink transmission on carriers other than {carrier#1, carrier#2}.

[0133] When mod(slotindex / m,P) = 2, that is, pairindex = 2, it can be determined that the uplink frequency band group in which the uplink transmission handover occurs is uplink frequency band group #2, that is, the terminal is on the carriers {carrier#3, carrier#4} corresponding to uplink frequency band group #2.

[0134] Uplink transmission switching is performed during this process, so that the network device does not schedule or configure the terminal to perform uplink transmission on carriers other than {carrier#3, carrier#4}.

[0135] In one embodiment, the method further includes: determining that the effective period of the first uplink frequency band group in which the terminal is currently performing uplink transmission switching has ended, and indicating that the uplink frequency band used by the terminal for uplink transmission does not belong to the first uplink frequency band group, and determining that the terminal switches to the second uplink frequency band group for uplink transmission switching.

[0136] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, the network device can determine whether the effective period of the first uplink frequency band group in which the terminal is currently performing uplink transmission handover has ended. If it has ended, then it can be determined that the terminal changes the uplink frequency band group in which it performs uplink transmission handover. However, changing the uplink frequency band group in which the terminal performs uplink transmission handover requires changing some internal logic of the terminal, which incurs certain overhead.

[0137] Therefore, it can be further determined whether the uplink frequency band indicated to the terminal for uplink transmission belongs to the first uplink frequency band group.

[0138] If the uplink frequency band indicated to the terminal by the network device for uplink transmission still belongs to the first uplink frequency band group, then uplink transmission switching within the first uplink frequency band group can still switch to the uplink frequency band indicated by the network device, satisfying communication requirements. Therefore, in this case, it can be determined that the terminal does not change the uplink frequency band group in which it performs uplink transmission switching, that is, it still performs uplink transmission switching among the uplink frequency bands included in the first uplink frequency band group, which helps to reduce the terminal's power consumption.

[0139] If the uplink frequency band indicated to the terminal by the network device for uplink transmission is still not in the first uplink frequency band group, then uplink transmission switching within the uplink frequency band of the first uplink frequency band group cannot switch to the uplink frequency band indicated by the network device, thus failing to meet communication requirements. Therefore, in this case, it can be determined that the terminal changes the uplink frequency band group in which it performs uplink transmission switching, for example, switching to the second uplink frequency band group, and performing uplink transmission switching between the uplink frequency bands included in the second uplink frequency band group in order to meet communication needs.

[0140] In one embodiment, the method further includes: determining that the timer corresponding to the first uplink frequency band group in which the terminal is currently performing uplink transmission switching has timed out, and determining that the terminal switches to the second uplink frequency band group for uplink transmission switching.

[0141] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, each uplink frequency band group can correspond to a timer. If the timer corresponding to the first uplink frequency band group where the current uplink transmission handover is taking place times out, it can be determined that the terminal changes the uplink frequency band group on which the uplink transmission handover is based, for example, switching to the second uplink frequency band group for uplink transmission handover.

[0142] In one embodiment, the timer starts when uplink transmission within the uplink band included in the first uplink band group ends and restarts when uplink transmission occurs within the uplink band included in the first uplink band group. This avoids the timer timing out when uplink transmission occurs within the uplink band included in the first uplink band group, thus preventing a change in the uplink band group on which the uplink transmission switching is based and ensuring that uplink transmissions within the uplink band included in the first uplink band group can be successfully completed.

[0143] In one embodiment, the method further includes: when it is determined that the service of the terminal meets preset conditions, the terminal switches from the first uplink frequency band group where it is currently performing uplink transmission switching to the second uplink frequency band group for uplink transmission switching.

[0144] In one embodiment, the uplink frequency band group on which the terminal performs uplink transmission handover can be changed. For example, the network device can analyze the services communicating with the terminal, and if the services meet preset conditions, determine that the terminal should switch from the first uplink frequency band group where it is currently performing uplink transmission handover to the second uplink frequency band group to ensure that service requirements are met.

[0145] In one embodiment, the preset conditions include at least one of the following: the service arrival rate is lower than the arrival rate value; the service priority is higher or lower than the priority threshold; the service quality is lower than the service quality threshold.

[0146] For example, if the service arrival rate is lower than the arrival rate value when performing uplink transmission handover in the first uplink frequency band group, it is difficult to meet the service's arrival rate requirements. Therefore, it can be determined that the terminal will switch to the second uplink frequency band group for uplink transmission handover in order to meet the service's arrival rate requirements.

[0147] For example, if the service quality falls below the service quality threshold during uplink transmission handover in the first uplink frequency band group, it will be difficult to meet the service quality requirements. Therefore, it can be determined that the terminal will switch to the second uplink frequency band group for uplink transmission handover in order to meet the service quality requirements.

[0148] For example, if the uplink transmission handover is performed in the first uplink frequency band group and the priority of the service to be performed is higher than the priority threshold, then when it is determined that the service is performed in the uplink frequency band corresponding to the first uplink frequency band group, the needs of the relatively high priority (higher than the priority threshold) service cannot be met. Therefore, it can be determined that the terminal will choose to switch to the second uplink frequency band group for uplink transmission handover in order to meet the needs of the relatively high priority service.

[0149] For example, if the uplink transmission handover is performed in the first uplink frequency band group and the priority of the service to be performed is lower than the priority threshold, then when the uplink frequency band in the first uplink frequency band group is used for services with relatively higher priority (above the priority threshold), then it can be determined that the terminal will choose to switch to the second uplink frequency band group for uplink transmission handover, so as to avoid services with relatively lower priority (below the priority threshold) occupying the uplink frequency band in the first uplink frequency band group.

[0150] In one embodiment, the method further includes: determining an uplink frequency band group candidate set according to a protocol agreement or indicating the uplink frequency band group candidate set to the terminal, wherein the first uplink frequency band group and the second uplink frequency band group belong to the uplink frequency band group candidate set.

[0151] In one embodiment, the method includes: determining, according to a protocol, an initial uplink frequency band group for the terminal to perform uplink transmission switching, or indicating the initial uplink frequency band group to the terminal.

[0152] It can be determined that when the terminal initially performs uplink transmission switching, it performs uplink transmission switching between uplink frequency bands included in the initial uplink frequency band group. The initial uplink frequency band group can be determined and indicated to the terminal by the network device, or it can be determined based on the protocol agreement.

[0153] The uplink frequency band group candidate set can be used to determine the uplink frequency band group that the terminal needs to switch to when changing the uplink transmission handover. For example, when performing an uplink transmission handover between uplink frequency bands included in the first uplink frequency band group, if it is necessary to change the uplink frequency band group on which the uplink transmission handover is based, then the second uplink frequency band group can be selected from the uplink frequency band group candidate set, and then the uplink transmission handover can be performed in the second uplink frequency band group, that is, the uplink transmission handover can be performed between the uplink frequency bands included in the second uplink frequency band group. The uplink frequency band group candidate set can be determined and indicated to the terminal by the network device, or it can be determined based on the protocol agreement.

[0154] The embodiments of this disclosure also propose an uplink transmission switching system, including a terminal and a network device, wherein the terminal is configured to implement the uplink transmission switching method described in any of the above embodiments, and the network device is configured to implement the uplink transmission control method described in any of the above embodiments.

[0155] In one embodiment, the terminal may determine the uplink frequency band group to which the uplink transmission handover will take place, and the network device may also determine the uplink frequency band group to which the terminal will take the uplink transmission handover.

[0156] On the one hand, network devices can schedule or configure the terminal to perform uplink transmission only within the uplink frequency band of the determined uplink frequency band group, and not schedule or configure the terminal to perform uplink transmission in the uplink frequency band outside the uplink frequency band group.

[0157] On the other hand, the terminal only needs to prepare for communication on the uplink frequency band within the uplink frequency band group (such as preparation for software, hardware, handover process, etc.), without needing to prepare for communication on the uplink frequency band outside the uplink frequency band group, which helps to reduce the complexity of the terminal performing uplink transmission handover.
