Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a switching configuration method and apparatus. Background Technology

[0002] In related technologies, the number of frequency bands supported by uplink antenna switching has been expanded from 2 to 3 or 4.

[0003] To ensure that terminal devices have sufficient time to switch antennas, a handover gap is set. During the handover gap, the terminal device does not expect network-side equipment (such as base stations) to schedule uplink transmissions on the relevant band. For example, if a handover occurs between band A and band B, and the handover gap is the time required for the handover between band A and band B, then during the handover gap, the terminal device will complete the antenna handover between band A and band B, while the network-side equipment will not schedule uplink transmissions on band A and band B during the handover gap. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network-side device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, there may be two or more network-side devices and two or more terminal devices. Figure 1 The communication system 10 shown is exemplified by including a network-side device 101 and a terminal device 102.

[0034] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

For example, the network-side device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network-side device 101. The network-side device 101 provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of the network-side device 101 can be separated.

[0037] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0038] In addition, the following points are provided to facilitate understanding of the embodiments disclosed herein.

[0039] First, in the embodiments of this disclosure, "for indicating" can include both direct and indirect indication. When describing information as indicating A, it can include that the information carries A, or it can also include that the information directly or indirectly indicates A, without necessarily implying that the information carries A.

[0040] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent.

[0041] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This disclosure does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol.

[0042] Second, in the embodiments shown below, the terms "first," "second," and various numerical designations (e.g., #1, #2) are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of this disclosure. For example, "first" and "second" in the embodiments of this disclosure can be used to distinguish types, not to distinguish object content.

[0043] Third, the “protocol” involved in the embodiments of this disclosure may refer to standard protocols in the field of communication, such as LTE protocol, NR protocol, WLAN protocol and related protocols in other communication systems, and this disclosure does not limit it.

[0044] Fourth, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can be single or multiple.

[0045] Fifth, this disclosure provides multiple implementation methods to clearly illustrate the technical solutions of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0046] Version 18 (Rel-18) expands the number of supported uplink transmit switching (UL Tx switching) from 2 to 3 or 4 bands. In versions 16 / 17 (Rel-16 / 17), a switching gap was set to ensure that terminal devices had sufficient time to switch antennas. During the switching gap, the terminal device does not expect network-side devices (such as base stations) to schedule uplink transmissions on the relevant bands. For example, if a switch occurs between band A and band B, and the switching gap is the time required for the switch between band A and band B, then during the switching gap, the terminal device will complete the antenna switch between band A and band B, while the network-side devices will not schedule uplink transmissions on band A and band B during the switching gap.

[0047] The handover period can be configured for each serving cell. A parameter (boolean) variable represents whether a handover period exists on the corresponding carrier (frequency band). TRUE indicates that there is a handover period on a certain carrier (frequency band), and FALSE indicates that there is no handover period on that carrier (frequency band).

[0048] Furthermore, if two uplink handovers are triggered within any two consecutive reference slots, resulting in uplink transmissions on more than two bands, the time interval between the end of all transmissions prior to the first uplink handover and the start of all transmissions after the second uplink handover within the two reference slots is expected to be no less than a minimum time (or minimum separation time). The minimum time is set to {0, 500 µs}.

[0049] In related technologies, when multiple frequency bands for uplink antenna switching correspond to different switching periods, the terminal device cannot determine which frequency band's corresponding switching period to use as the target switching period.

[0050] Based on this, embodiments of this disclosure provide a handover configuration method and apparatus. A terminal device, in response to multiple frequency bands corresponding to different handover periods for uplink antenna handover, receives handover indication information sent by a network-side device. The handover indication information indicates information about a target frequency band among the multiple frequency bands. Based on the handover indication information, the target frequency band is determined, and the target handover period is determined as the handover period corresponding to the target frequency band. Thus, the terminal device can determine the handover period corresponding to a target frequency band as the target handover period, avoiding uplink antenna handover failure due to the inability to determine the handover period.

[0051] It should be noted that in the handover configuration method and apparatus provided in this disclosure, the frequency band can be replaced with a carrier or serving cell, etc. In this embodiment, the frequency band is used as an example for illustration.

[0052] The following description, in conjunction with the accompanying drawings, details a switching configuration method and apparatus provided in this disclosure.

[0053] Please see Figure 2 , Figure 2 This is a flowchart of a configuration switching method provided in an embodiment of this disclosure. Figure 2 As shown, this method is executed by a terminal device, and the method may include, but is not limited to, the following steps: S21: Receive handover indication information sent by the network-side device, wherein the handover indication information is used to indicate the information of a target frequency band among multiple frequency bands, the multiple frequency bands are used for uplink antenna switching, and each corresponds to a different handover period.

[0054] S22: Based on the handover instruction information, determine the handover period corresponding to the target frequency band as the target handover period.

[0055] In this embodiment of the present disclosure, the terminal device can receive handover indication information sent by the network side device. The handover indication information is used to indicate information of a target frequency band among multiple frequency bands. The multiple frequency bands are used for uplink antenna switching and each corresponds to a different handover period.

[0056] Understandably, when uplink antenna switching involves more than two frequency bands, one of these bands may belong to different band combinations. For example, band A belongs to band pair {A,B} and band pair {A,C}. For the first band pair {A,B}, a switching period can be configured on band B, and for the second band pair {A,C}, a switching period can be configured on band A. Therefore, both band A and band B are configured with switching periods. However, if the switching periods configured for band A and band B are different, when uplink antenna switching occurs between band A and band B, the terminal device cannot determine which switching period to select.

[0057] In this embodiment of the disclosure, in the above-described situation, the terminal device can receive handover indication information sent by the network-side device. This handover indication information is used to indicate information about a target frequency band among multiple frequency bands. In this case, the terminal device can determine a target frequency band based on the handover indication information.

[0058] The handover indication information is used to indicate the target frequency band among multiple frequency bands. The handover indication information can indicate that the specific parameters of the target frequency band are different from those of other frequency bands among multiple frequency bands. Thus, the terminal device can determine a unique target frequency band with specific parameters that are different from those of other frequency bands based on the handover indication information.

[0059] In this embodiment of the disclosure, certain parameters may reuse related parameters, or new parameters may be used.

[0060] For example, a specific parameter can be the priority corresponding to a frequency band, and the priority of the target frequency band is different from the priority of other frequency bands among the multiple frequency bands.

[0061] For example, the priority corresponding to the target frequency band can be the highest priority (at which time the priority of other frequency bands among multiple frequency bands is not the highest priority), the second highest priority (at which time the priority of other frequency bands among multiple frequency bands is not the second highest priority), the lowest priority (at which time the priority of other frequency bands among multiple frequency bands is not the lowest priority), or the second lowest priority (at which time the priority of other frequency bands among multiple frequency bands is not the second lowest priority), and so on.

[0062] For example, the specific parameter can be a parameter that characterizes whether a switching cycle exists on a frequency band. When the specific parameter of a certain frequency band is a first value, it indicates that a switching cycle exists on that frequency band. Conversely, when the specific parameter of a certain frequency band is not a first value, it indicates that a switching cycle does not exist on that frequency band.

[0063] For example: a specific parameter of the target frequency band is the first value (at this time, the specific parameters of other frequency bands in the multiple frequency bands are not the first value).

[0064] In this embodiment of the disclosure, the handover indication information is used to indicate information about a target frequency band among multiple frequency bands. The handover indication information may indicate that specific parameters of the target frequency band are different from those of other frequency bands among the multiple frequency bands. Therefore, the terminal device can determine a unique target frequency band based on the specific parameters indicated by the handover indication information. In this case, the terminal device can determine the handover period corresponding to the target frequency band as the target handover period. Thus, the terminal device can determine a handover period as the target handover period, which can avoid uplink antenna handover failure due to the inability to determine the handover period.

[0065] In some embodiments, multiple frequency bands correspond to different priorities.

[0066] In some embodiments, the terminal device determines the handover period corresponding to the target frequency band as the target handover period based on the handover indication information, including: determining the highest priority frequency band among multiple frequency bands as the target frequency band based on the handover indication information, and determining the handover period corresponding to the target frequency band as the target handover period; or determining the lowest priority frequency band among multiple frequency bands as the target frequency band based on the handover indication information, and determining the handover period corresponding to the target frequency band as the target handover period.

[0067] In this embodiment of the present disclosure, the terminal device receives handover indication information sent by the network side device. The handover indication information is used to indicate information of a target frequency band among multiple frequency bands, and the multiple frequency bands correspond to different priorities.

[0068] In this case, the terminal device can determine the highest priority frequency band among multiple frequency bands as the target frequency band based on the handover instruction information, and determine the handover period corresponding to the target frequency band as the target handover period. Alternatively, the terminal device can also determine the lowest priority frequency band among multiple frequency bands as the target frequency band based on the handover instruction information, and determine the handover period corresponding to the target frequency band as the target handover period.

[0069] In some embodiments, the switching indication information is used to indicate at least one of the following: Target frequency band; The frequency band where the first parameter has a specific value is the target frequency band; Switching is performed between the first frequency band pairs in multiple frequency bands, with the two frequency bands of the first frequency band pair corresponding to different priorities; Switching between pairs of second frequency bands in multiple frequency bands, where only one of the two frequency bands in the second frequency band pair has a specific first parameter; Multiple frequency bands with specific values ​​for their first parameter correspond to different priorities; The highest priority frequency band is the target frequency band; The lowest priority frequency band is the target frequency band; Among multiple frequency bands with a specific first parameter value, the frequency band with the highest priority is the target frequency band; Among multiple frequency bands with a specific first parameter, the frequency band with the lowest priority is the target frequency band.

[0070] In this embodiment of the disclosure, the switching indication information can be used to indicate the target frequency band.

[0071] In this embodiment of the disclosure, the switching indication information can be used to indicate that the frequency band with a first parameter of a specific value is the target frequency band.

[0072] In this embodiment of the disclosure, the switching indication information can be used to indicate switching between first frequency band pairs in multiple frequency bands, with the two frequency bands of the first frequency band pair corresponding to different priorities.

[0073] In this embodiment of the disclosure, the switching indication information can be used to indicate switching between pairs of second frequency bands in multiple frequency bands, wherein only one of the two frequency bands in the second frequency band pair has a specific value for its first parameter.

[0074] It is understandable that uplink antenna switching can occur between a pair of frequency bands, in which case the pair of frequency bands in which the uplink antenna switching occurs includes a target frequency band with a first parameter of a specific value.

[0075] Of course, uplink antenna switching can also occur between multiple frequency band pairs. In this case, each frequency band pair in which uplink antenna switching occurs can include a target frequency band with a first parameter of a specific value.

[0076] In this embodiment of the disclosure, the switching indication information can be used to indicate that multiple frequency bands with a specific value for the first parameter correspond to different priorities.

[0077] In this embodiment of the disclosure, the switching indication information can be used to indicate that the highest priority frequency band is the target frequency band.

[0078] In this embodiment of the disclosure, the switching indication information can be used to indicate that the frequency band with the lowest priority is the target frequency band.

[0079] In this embodiment of the disclosure, the switching indication information can be used to indicate that the highest priority frequency band among multiple frequency bands with a first parameter of a specific value is the target frequency band.

[0080] In this embodiment of the disclosure, the switching indication information can be used to indicate the lowest priority frequency band among multiple frequency bands with a specific value for the first parameter as the target frequency band.

[0081] It should be noted that in the above embodiments, the first parameter can be a parameter from related technologies, or a new parameter. Furthermore, the first parameter is a specific value, which can be a numerical value, such as "1", or a symbol, such as "TRUE", or other forms, etc. This disclosure does not impose specific limitations on this.

[0082] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0083] In some embodiments, the terminal device receives configuration information sent by the network-side device, wherein the configuration information is used to indicate the priority corresponding to the frequency band.

[0084] In this embodiment of the disclosure, the terminal device can receive configuration information sent by the network-side device, and determine the priority of the frequency band if the configuration information indicates the priority of the frequency band.

[0085] In some embodiments, the terminal device receives a radio resource control (RRC) message sent by the network-side device, the RRC message including configuration information.

[0086] In some embodiments, the configuration information is used to indicate at least one of the following: The first list includes the priorities corresponding to different frequency bands; The second list includes the priorities corresponding to different frequency band groups.

[0087] In this embodiment of the disclosure, the configuration information can be used to indicate a first list, which includes the priorities corresponding to different frequency bands. Thus, the terminal device can determine the priorities corresponding to different frequency bands.

[0088] In this embodiment of the disclosure, configuration information can be used to indicate a second list, which includes the priorities corresponding to different frequency band groups. Therefore, the terminal device can determine the priorities corresponding to different frequency band groups, and given the frequency band group to which a frequency band belongs, it can determine the priority corresponding to that frequency band.

[0089] For example, in the second list of configuration information, the frequency band group can be a group consisting of frequency band pairs corresponding to uplink antenna switching, or the frequency band group can be a group consisting of a random number of frequency bands, or the frequency band group can be a group consisting of frequency bands corresponding to a specific function set.

[0090] In the case where a frequency band group is a group composed of frequency bands corresponding to a specific function set, the specific function set can be a group composed of two frequency bands and two other frequency bands when switching from two frequency bands to two other frequency bands.

[0091] For example, a frequency band group includes frequency band #1, frequency band #2, frequency band #3 and frequency band #4. Uplink antenna switching is performed from frequency band #1 and frequency band #2 to frequency band #3 and frequency band #4, or uplink antenna switching is performed from frequency band #1 and frequency band #3 to frequency band #2 and frequency band #4, and so on.

[0092] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0093] By implementing the embodiments of this disclosure, the terminal device receives handover indication information sent by the network-side device. The handover indication information indicates information about a target frequency band among multiple frequency bands. These multiple frequency bands are used for uplink antenna switching and each corresponds to a different handover period. Based on the handover indication information, the handover period corresponding to the target frequency band is determined as the target handover period. Therefore, the terminal device can determine the handover period corresponding to a target frequency band as the target handover period, thus avoiding uplink antenna switching failure due to the inability to determine the handover period.

[0094] Please see Figure 3a , Figure 3a This is a flowchart of another configuration switching method provided in this disclosure.

The switching indication information can be used to indicate switching between the second frequency band pair, wherein only one of frequency bands #1 and frequency band #2 has a specific value for its first parameter.

[0179] In this embodiment of the present disclosure, when the switching indication information indicates that there are multiple frequency bands with a first parameter of a specific value, and the multiple frequency bands with a first parameter of a specific value include a target frequency band with the lowest priority, the terminal device can determine a target frequency band with the lowest priority among the multiple frequency bands with a first parameter of a specific value.

[0180] For example, multiple frequency bands include frequency band #1, frequency band #2, frequency band #3, and frequency band #4. The handover indication information can be used to indicate that the first parameter of frequency bands #1, #3, and #4 are all specific values, wherein frequency band #1 has a priority of second-level priority, frequency band #3 has a priority of first-level priority, and frequency band #4 has a priority of first-level priority. Therefore, the terminal device can determine the frequency band with the lowest priority (frequency band #1) among the multiple frequency bands (frequency band #1, #3, and #4) with specific first parameter values ​​as the target frequency band.

[0181] It should be noted that in the above embodiments, the first parameter can be a parameter from related technologies, or a new parameter. Furthermore, the first parameter is a specific value, which can be a numerical value, such as "1", or a symbol, such as "TRUE", or other forms, etc. This disclosure does not impose specific limitations on this.

[0182] It should be noted that the above examples are for illustrative purposes only and are not intended to limit the specific embodiments of this disclosure. Multiple frequency bands may also include two frequency bands, three frequency bands, etc.

[0183] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0184] It should be noted that in the embodiments of this disclosure, S101 and S102 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and S22 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0185] By implementing the embodiments of this disclosure, the terminal device receives handover indication information sent by the network-side device. The handover indication information indicates that there are multiple frequency bands with a specific first parameter value, and that the lowest priority frequency band among these multiple frequency bands with a specific first parameter value is the target frequency band. The multiple frequency bands are used for uplink antenna handover and each corresponds to a different handover period. Based on the handover indication information, the handover period corresponding to the target frequency band is determined as the target handover period. Therefore, the terminal device can determine the handover period corresponding to a target frequency band as the target handover period, thus avoiding uplink antenna handover failure due to the inability to determine the handover period.

[0186] Please see Figure 11 , Figure 11 This is a flowchart of a capability reporting method provided in an embodiment of this disclosure. For example... Figure 11 As shown, this method is executed by a terminal device, and the method may include, but is not limited to, the following steps: S111: Report capability indication information to the network-side device. The capability indication information is used to indicate the minimum time, which is the time interval between two uplink antenna handovers performed on two consecutive time slots.

[0187] In this embodiment of the disclosure, the terminal device supports reporting capability indication information to the network-side device to indicate the minimum time.

[0188] Understandably, if two uplink handovers are triggered within any two consecutive reference slots, resulting in uplink transmissions on more than two bands, the time interval between the end of all transmissions before the first uplink handover and the start of all transmissions after the second uplink handover within the two reference slots is expected to be no less than the minimum time (or minimum separation time). The minimum time is set to {0, 500µs}.

[0189] In this embodiment of the disclosure, the terminal device can report capability indication information to the terminal device based on its capabilities, indicating the minimum time.

[0190] In some embodiments, the capability indication information is used to indicate at least one of the following: After an uplink handover occurs between the first frequency band pairs, an uplink handover occurs between the second frequency band pairs, and the time interval between the two uplink handovers is: After an uplink handover occurs between the first frequency band group, an uplink handover occurs between the second frequency band group, and the time interval between the two uplink handovers is specified.

[0191] In this embodiment of the disclosure, the capability indication information is used to indicate the minimum time, which can be used to indicate the time interval between two uplink handovers, after an uplink handover occurs between the first frequency band pair and an uplink handover occurs between the second frequency band pair.

[0192] In this embodiment of the disclosure, the capability indication information is used to indicate the minimum time, which can be used to indicate the time interval between uplink handovers between the first frequency band group and the second frequency band group.

[0193] It is understandable that terminal devices can report capability indication information at the granularity of frequency bands, or at the granularity of frequency band groups.

[0194] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0195] It should be noted that in the embodiments of this disclosure, S111 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as S21 and S22 and / or S31a and S32a and / or S31b and S32b and / or S41a and S42a and / or S41b and S42b and / or S51 and S52 and / or S61 and S62 and / or S71 and S72 and / or S81 and S82 and / or S91 and S92 and / or S101 and S102. The embodiments of this disclosure do not limit this.

[0196] By implementing the embodiments of this disclosure, the terminal device reports capability indication information to the network-side device. This capability indication information indicates a minimum time interval, which is the time interval between two consecutive uplink antenna handovers. This enables the terminal device to report capability indication information to the network-side device to indicate the minimum time interval.

[0197] Please see Figure 12 , Figure 12 This is a flowchart of yet another switching configuration method provided in this disclosure. For example... Figure 12 As shown, this method is executed by a terminal device, and the method may include, but is not limited to, the following steps: S121: Determine that the target switching period is located in the first time slot where the first symbol of the uplink transmission is located; or determine that the target switching period is located in the second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located; or, in the case where the first symbol of the uplink transmission is located in a specific symbol of the first time slot, determine that the target switching period is located in the second time slot adjacent to the first time slot.

[0198] In this embodiment of the disclosure, when the terminal device determines the target switching period for performing uplink antenna switching, it can determine that the target switching period is located in the first time slot where the first symbol of the uplink transmission is located.

[0199] For example, if the first time slot where the first symbol of the uplink transmission is located is slot#1, the terminal device can determine that the target switching cycle is located in slot#1.

[0200] In this embodiment of the disclosure, when the terminal device determines the target switching period for performing uplink antenna switching, it can determine that the target switching period is located in the second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located.

[0201] For example, if the first time slot where the first symbol of the uplink transmission is located is slot#1, the terminal device can determine that the target switching period is located in the second time slot adjacent to slot#1, slot#2.

[0202] In this embodiment of the disclosure, when the terminal device determines the target switching period for performing uplink antenna switching, and the first symbol of the uplink transmission is located in a specific symbol of the first time slot, it can determine that the target switching period is located in the second time slot adjacent to the first time slot. Among them, the specific symbol can be any one of the following symbols: the first symbol, the second symbol, the third symbol, the fourth symbol, the fifth symbol, the sixth symbol, the seventh symbol, the eighth symbol, the ninth symbol, the tenth symbol, the eleventh symbol, the twelfth symbol, the thirteenth symbol, and the last symbol.

[0203] For example, if a specific symbol is the first symbol, and the first symbol transmitted by the terminal device in the uplink is the first symbol of the first time slot #1, the terminal device can determine that the target switching period is located in the second time slot #2 adjacent to the first time slot #1.

[0204] For example, if the specific symbol is the tail symbol, and the first symbol transmitted by the terminal device in the uplink is the tail symbol of the first time slot #1, the terminal device can determine that the target switching period is located in the second time slot #2 adjacent to the first time slot #1.

[0205] It should be noted that the above examples are for illustrative purposes only, and specific symbols may be other symbols. This disclosure does not impose specific limitations on this embodiment.

[0206] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0207] It should be noted that in the embodiments of this disclosure, S121 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as S21 and S22 and / or S31a and S32a and / or S31b and S32b and / or S41a and S42a and / or S41b and S42b and / or S51 and S52 and / or S61 and S62 and / or S71 and S72 and / or S81 and S82 and / or S91 and S92 and / or S101 and S102 and / or S111. The embodiments of this disclosure do not limit this.

[0208] By implementing the embodiments of this disclosure, the terminal device determines that the target handover period is located in a first time slot where the first symbol of the uplink transmission is located; or determines that the target handover period is located in a second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located; or, in the case where the first symbol of the uplink transmission is located in a specific symbol of the first time slot, determines that the target handover period is located in a second time slot adjacent to the first time slot. Thus, the terminal device can determine the time slot where the target handover period is located.

[0209] Please see Figure 13 , Figure 13 This is a flowchart of yet another switching configuration method provided in this disclosure. For example... Figure 13 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps: S131: Send handover indication information to the terminal device, wherein the handover indication information is used to indicate the information of a target frequency band among multiple frequency bands, the multiple frequency bands are used for uplink antenna switching and each corresponds to a different handover period, and the handover indication information is used by the terminal device to determine the handover period corresponding to the target frequency band as the target handover period according to the handover indication information.

[0210] In this embodiment of the disclosure, when the multiple frequency bands of uplink antenna switching correspond to different switching periods, the network-side device can send switching indication information to the terminal device, wherein the switching indication information is used to indicate the information of the target frequency band among the multiple frequency bands.

[0211] Understandably, when uplink antenna switching involves more than two frequency bands, one of these bands may belong to different band combinations. For example, band A belongs to band pairs {A,B} and {A,C}. For the first band pair {A,B}, a switching period can be configured on band B, and for the second band pair {A,C}, a switching period can be configured on band A. Therefore, both band A and band B are configured with switching periods. However, if the switching periods configured for band A and band B are different, when uplink antenna switching occurs between band A and band B, the terminal device cannot determine which switching period to select.

[0212] In this embodiment of the disclosure, in the above-described situation, the network-side device can send handover indication information to the terminal device. The handover indication information is used to indicate information about a target frequency band among multiple frequency bands. In this case, the handover indication information is used by the terminal device to determine the handover period corresponding to the target frequency band as the target handover period.

[0213] The handover indication information is used to indicate the target frequency band among multiple frequency bands. The handover indication information can indicate that the specific parameters of the target frequency band are different from those of other frequency bands among multiple frequency bands. Thus, the handover indication information can be used by the terminal device to determine a unique target frequency band whose specific parameters are different from those of other frequency bands based on the handover indication information.

[0214] In this embodiment of the disclosure, certain parameters may reuse related parameters, or new parameters may be used.

[0215] For example, a specific parameter can be the priority corresponding to a frequency band, and the priority of the target frequency band is different from the priority of other frequency bands among the multiple frequency bands.

[0216] For example, the priority corresponding to the target frequency band can be the highest priority (at which time the priority of other frequency bands among multiple frequency bands is not the highest priority), the second highest priority (at which time the priority of other frequency bands among multiple frequency bands is not the second highest priority), the lowest priority (at which time the priority of other frequency bands among multiple frequency bands is not the lowest priority), or the second lowest priority (at which time the priority of other frequency bands among multiple frequency bands is not the second lowest priority), and so on.

[0217] For example, the specific parameter can be a parameter that characterizes whether a switching cycle exists on a frequency band. When the specific parameter of a certain frequency band is a first value, it indicates that a switching cycle exists on that frequency band. Conversely, when the specific parameter of a certain frequency band is not a first value, it indicates that a switching cycle does not exist on that frequency band.

[0218] For example: a specific parameter of the target frequency band is the first value (at this time, the specific parameters of other frequency bands in the multiple frequency bands are not the first value).

[0219] In this embodiment of the disclosure, the switching indication information is used to indicate the information of the target frequency band among multiple frequency bands. The switching indication information can indicate that the specific parameters of the target frequency band are different from those of other frequency bands among multiple frequency bands. Thus, the terminal device can determine a unique target frequency band based on the specific parameters indicated by the switching indication information.

[0220] In some embodiments, multiple frequency bands correspond to different priorities.

[0221] In some embodiments, the network-side device may determine multiple frequency bands with different priorities before sending handover instruction information to the terminal device.

[0222] In this embodiment of the disclosure, the network-side device can first determine multiple frequency bands with different priorities, and then send switching indication information to the terminal device to switch the information used to indicate a target frequency band among the multiple frequency bands.

[0223] In some embodiments, the switching indication information is used to indicate at least one of the following: Target frequency band; the frequency band with a specific first parameter value is the target frequency band; switching between first frequency band pairs in multiple frequency bands, with each of the two frequency bands in the first frequency band pair corresponding to a different priority; switching between second frequency band pairs in multiple frequency bands, with only one of the two frequency bands in the second frequency band pair having a specific first parameter value; multiple frequency bands with a specific first parameter value corresponding to different priorities; the frequency band with the highest priority is the target frequency band; the frequency band with the lowest priority is the target frequency band; the frequency band with the highest priority among multiple frequency bands with a specific first parameter value is the target frequency band; the frequency band with the lowest priority among multiple frequency bands with a specific first parameter value is the target frequency band.

[0224] In this embodiment of the disclosure, the switching indication information can be used to indicate the target frequency band.

[0225] In this embodiment of the disclosure, the switching indication information can be used to indicate that the frequency band with a first parameter of a specific value is the target frequency band.

[0226] In this embodiment of the disclosure, the switching indication information can be used to indicate switching between first frequency band pairs in multiple frequency bands, with the two frequency bands of the first frequency band pair corresponding to different priorities.

[0227] In this embodiment of the disclosure, the switching indication information can be used to indicate switching between pairs of second frequency bands in multiple frequency bands, wherein only one of the two frequency bands in the second frequency band pair has a specific value for its first parameter.

[0228] In this embodiment of the disclosure, the switching indication information can be used to indicate that multiple frequency bands with a specific value for the first parameter correspond to different priorities; In this embodiment of the disclosure, the switching indication information can be used to indicate that the highest priority frequency band is the target frequency band.

[0229] In this embodiment of the disclosure, the switching indication information can be used to indicate that the frequency band with the lowest priority is the target frequency band.

[0230] In this embodiment of the disclosure, the switching indication information can be used to indicate that the highest priority frequency band among multiple frequency bands with a first parameter of a specific value is the target frequency band.

[0231] In this embodiment of the disclosure, the switching indication information can be used to indicate the lowest priority frequency band among multiple frequency bands with a specific value for the first parameter as the target frequency band.

[0232] It should be noted that in the above embodiments, the first parameter can be a parameter from related technologies, or a new parameter. Furthermore, the first parameter is a specific value, which can be a numerical value, such as "1", or a symbol, such as "TRUE", or other forms, etc. This disclosure does not impose specific limitations on this.

[0233] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0234] In some embodiments, the network-side device sends configuration information to the terminal device, wherein the configuration information is used to indicate the priority corresponding to the frequency band.

[0235] In this embodiment of the disclosure, the network-side device can send configuration information to the terminal device. If the configuration information indicates the priority of the frequency band, the priority of the frequency band can be determined.

[0236] In some embodiments, the network-side device may send configuration information to the terminal device by sending a radio resource control (RRC) message, which includes the configuration information.

[0237] In some embodiments, the configuration information is used to indicate at least one of the following: The first list includes the priorities corresponding to different frequency bands; The second list includes the priorities corresponding to different frequency band groups.

[0238] In this embodiment of the disclosure, the configuration information can be used to indicate a first list, which includes the priorities corresponding to different frequency bands. Thus, the priorities corresponding to different frequency bands can be indicated to the terminal device.

[0239] In this embodiment of the disclosure, the configuration information can be used to indicate a second list, which includes the priorities corresponding to different frequency band groups. Therefore, the terminal device can be informed of the priorities corresponding to frequency bands belonging to different frequency band groups.

[0240] For example, in the second list of configuration information, the frequency band group can be a group consisting of frequency band pairs corresponding to uplink antenna switching, or the frequency band group can be a group consisting of a random number of frequency bands, or the frequency band group can be a group consisting of frequency bands corresponding to a specific function set.

[0241] In the case where a frequency band group is a group composed of frequency bands corresponding to a specific function set, the specific function set can be a group composed of two frequency bands and two other frequency bands when switching from two frequency bands to two other frequency bands.

[0242] For example, a frequency band group includes frequency band #1, frequency band #2, frequency band #3 and frequency band #4. Uplink antenna switching is performed from frequency band #1 and frequency band #2 to frequency band #3 and frequency band #4, or uplink antenna switching is performed from frequency band #1 and frequency band #3 to frequency band #2 and frequency band #4, and so on.

[0243] In some embodiments, the network-side device determines the minimum time corresponding to the terminal device as a specific time, which is the time interval between two uplink antenna switching operations performed on two consecutive time slots.

[0244] In this embodiment of the disclosure, the network-side device can determine the minimum time corresponding to the terminal device as a specific time. The minimum time is the time interval between two uplink antenna switching operations performed on two consecutive time slots.

[0245] In this embodiment, the network-side device may determine a specific time according to the protocol, or it may determine a specific time based on the information reported by the terminal device, etc. This disclosure does not impose specific limitations on this.

[0246] Understandably, if two uplink handovers are triggered within any two consecutive reference slots, resulting in uplink transmissions on more than two bands, the time interval between the end of all transmissions before the first uplink handover and the start of all transmissions after the second uplink handover within the two reference slots is expected to be no less than the minimum time (or minimum separation time). The minimum time is set to {0, 500µs}.

[0247] In this embodiment of the disclosure, the network-side device can independently determine the minimum time corresponding to the terminal device as a specific time.

[0248] For example, the network-side device can determine the minimum time corresponding to the terminal device as a specific time, which can be any one of 0us, 100us, 200us, 500us, 1000us, etc.

[0249] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0250] By implementing the embodiments of this disclosure, the network-side device sends handover indication information to the terminal device. This handover indication information indicates information about a target frequency band among multiple frequency bands. These multiple frequency bands are used for uplink antenna switching and each corresponds to a different handover period. The handover indication information is used by the terminal device to determine the handover period corresponding to the target frequency band as the target handover period. Therefore, the network-side device can instruct the terminal device to determine the target frequency band and thus the corresponding handover period, avoiding uplink antenna switching failure due to the inability to determine the handover period.

[0251] Please see Figure 14 , Figure 14 This is a flowchart of another capability reporting method provided in an embodiment of this disclosure. For example... Figure 14 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps: S141: Receive capability indication information reported by the terminal device, wherein the capability indication information is used to indicate the minimum time, which is the time interval between two uplink antenna switchings performed on two consecutive time slots.

[0252] In this embodiment of the disclosure, the network-side device can receive capability indication information reported by the terminal device, wherein the capability indication information is used to indicate the minimum time.

[0253] Understandably, if two uplink handovers are triggered within any two consecutive reference slots, resulting in uplink transmissions on more than two bands, the time interval between the end of all transmissions before the first uplink handover and the start of all transmissions after the second uplink handover within the two reference slots is expected to be no less than the minimum time (or minimum separation time). The minimum time is set to {0, 500µs}.

[0254] In this embodiment of the disclosure, the network-side device can receive capability indication information reported by the terminal device, wherein the capability indication information is used to indicate a minimum time. Therefore, the network-side device can determine the minimum time for the terminal device based on the capability indication information reported by the terminal device.

[0255] In some embodiments, the capability indication information is used to indicate at least one of the following: After an uplink handover occurs between the first frequency band pairs, an uplink handover occurs between the second frequency band pairs, and the time interval between the two uplink handovers is: After an uplink handover occurs between the first frequency band group, an uplink handover occurs between the second frequency band group, and the time interval between the two uplink handovers is specified.

[0256] In this embodiment of the disclosure, the capability indication information is used to indicate the minimum time, which can be used to indicate the time interval between two uplink handovers, after an uplink handover occurs between the first frequency band pair and an uplink handover occurs between the second frequency band pair.

[0257] In this embodiment of the disclosure, the capability indication information is used to indicate the minimum time, which can be used to indicate the time interval between uplink handovers between the first frequency band group and the second frequency band group.

[0258] It is understandable that terminal devices can report capability indication information at the granularity of frequency bands, or at the granularity of frequency band groups.

[0259] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0260] It should be noted that in the embodiments of this disclosure, S141 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S131 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0261] By implementing the embodiments of this disclosure, the terminal device reports capability indication information to the network-side device. This capability indication information indicates a minimum time interval, which is the time interval between two consecutive uplink antenna handovers. This enables the terminal device to report capability indication information to the network-side device to indicate the minimum time interval.

[0262] Please see Figure 15 , Figure 15 This is a flowchart of yet another switching configuration method provided in this disclosure. For example... Figure 15As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps: S151: Determine that the target switching period is located in the first time slot where the first symbol of the uplink transmission is located; or determine that the target switching period is located in the second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located; or, in the case where the first symbol of the uplink transmission is located in a specific symbol of the first time slot, determine that the target switching period is located in the second time slot adjacent to the first time slot.

[0263] In this embodiment of the disclosure, when the network-side device determines the target switching period for performing uplink antenna switching, it can determine that the target switching period is located in the first time slot where the first symbol of the uplink transmission is located.

[0264] For example, if the first time slot where the first symbol of the uplink transmission is located is slot#1, the network-side device can determine that the target switching cycle is located in slot#1.

[0265] In this embodiment of the disclosure, when the network-side device determines the target switching period for performing uplink antenna switching, it can determine that the target switching period is located in the second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located.

[0266] For example, if the first time slot where the first symbol of the uplink transmission is located is slot#1, the network-side device can determine that the target switching period is located in the second time slot adjacent to slot#1, slot#2.

[0267] In this embodiment of the disclosure, when the network-side device determines the target switching period for performing uplink antenna switching, and the first symbol of the uplink transmission is located in a specific symbol of the first time slot, it can determine that the target switching period is located in the second time slot adjacent to the first time slot. Among them, the specific symbol can be any one of the following symbols: the first symbol, the second symbol, the third symbol, the fourth symbol, the fifth symbol, the sixth symbol, the seventh symbol, the eighth symbol, the ninth symbol, the tenth symbol, the eleventh symbol, the twelfth symbol, the thirteenth symbol, and the last symbol.

[0268] For example, if a specific symbol is the first symbol, and the first symbol transmitted by the network-side device in the uplink is the first symbol of the first time slot #1, the network-side device can determine that the target switching period is located in the second time slot #2 adjacent to slot #1.

[0269] For example, if the specific symbol is the tail symbol, and the first symbol transmitted by the network-side device in the uplink is the tail symbol of the first time slot #1, the network-side device can determine that the target switching period is located in the second time slot #2 adjacent to the first time slot #1.

[0270] It should be noted that the above examples are for illustrative purposes only, and the specific symbols can be other symbols as well. This disclosure does not impose any specific limitations on this.

[0271] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0272] It should be noted that in the embodiments of this disclosure, S151 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S131 and / or S141 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0273] By implementing the embodiments of this disclosure, the network-side device determines that the target handover period is located in a first time slot where the first symbol of the uplink transmission is located; or determines that the target handover period is located in a second time slot adjacent to the first time slot where the first symbol of the uplink transmission is located; or, in the case where the first symbol of the uplink transmission is located in a specific symbol of the first time slot, determines that the target handover period is located in a second time slot adjacent to the first time slot. Thus, the network-side device can determine the time slot where the target handover period is located.

[0274] To facilitate understanding of the embodiments of this disclosure, an exemplary embodiment is provided.

[0275] In an exemplary embodiment, version 18 (Rel-18) supports uplink transmission switching (UL Tx switching), expanding the number of supported bands from 2 to 3 or 4. In version 16 / 17 (Rel-16 / 17) of the protocol, a switching gap is set to ensure that the terminal device has sufficient time to switch antennas. During the switching gap, the terminal device does not expect the network-side device (e.g., the base station) to schedule uplink transmission on the relevant band. For example, if the switching occurs between band A and band B, and the switching gap is N{AB}, then during the switching gap, the terminal device will complete the antenna switching between bands AB, while the network-side device will not schedule uplink transmission on band AB during the switching gap.

[0276] The handover period can be configured for each serving cell. A parameter (boolean) variable represents whether a handover period exists on the corresponding carrier (frequency band). TRUE indicates that there is a handover period on a certain carrier (frequency band), and FALSE indicates that there is no handover period on that carrier (frequency band).

[0277] Furthermore, if two uplink handovers are triggered within any two consecutive reference slots, resulting in uplink transmissions on more than two bands, the time interval between the end of all transmissions prior to the first uplink handover and the start of all transmissions after the second uplink handover within the two reference slots is expected to be no less than a minimum time (or minimum separation time). The minimum time is set to {0, 500 µs}.

[0278] 1. How to solve the problem of ambiguity in the band where the switching cycle is located? The relevant technologies meet the requirements for Rel-16 / 17 UL Tx switching primarily because only two bands are supported. For Rel-18 UL Tx switching, more than two bands are involved, and one of these bands may belong to different band combinations. For example, band A belongs to band pairs {A,B} and {A,C}. For the first band pair, the switching period can be located on band B, depending on the current configuration. On the other hand, the switching period for the second band pair is configured on band A.
