[0096] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive aspects to those skilled in the art. Features described in the description and / or shown in the figures can be combined in any suitable manner without departing from the scope of the present disclosure.

[0097] In addition, the accompanying drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and, together with the description, serve to explain the principles of the present disclosure. In the drawings:

[0098] Figure 1 A schematic diagram of an exemplary communication system architecture to which the uplink transmitter switching method of embodiments of the present disclosure can be applied is shown.

[0099] like Figure 1 As shown, the communication system may include terminal equipment 101, a network, and a core network.

[0100] The network is a medium used to provide a communication link between the terminal device 101 and the core network. It can be a wired network or a wireless network.

[0101] Optionally, the aforementioned wireless or wired networks use standard communication technologies and / or protocols. The network is typically the Internet, but can also be any network, including but not limited to Local Area Networks (LANs), Metropolitan Area Networks (MANs), Wide Area Networks (WANs), mobile, wired or wireless networks, private networks, or any combination of virtual private networks. In some embodiments, technologies and / or formats including Hyper Text Markup Language (HTML), Extensible Markup Language (XML), etc., are used to represent the data exchanged over the network. Furthermore, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) can be used to encrypt all or some links. In other embodiments, custom and / or dedicated data communication technologies can be used to replace or supplement the aforementioned data communication technologies.

[0102] The communication system can employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency-division Multiple Access (OFDMA), Single Carrier FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance. According to different network capacities, rates, delays, and other factors, the network can be divided into 2G (generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. In this disclosure, the network includes a network device 102, which can be a wireless access network node, for example; the core network includes a core network device. The wireless access network node can also be a base station. The network can provide network services for the terminal device 101 through the network device 102.

[0103] The terminal device 101, which can be referred to as a user equipment, a mobile terminal, a terminal, a mobile station, etc., is a device that provides voice and / or data connectivity for a user, and can be various electronic devices including, but not limited to, a smartphone, a tablet computer, a laptop computer, a desktop computer, a wearable device, an augmented reality device, a virtual reality device, etc.

[0104] Optionally, the application clients installed in different terminal devices 101 are the same, or the clients of the same type of application based on different operating systems. Based on the difference in terminal platforms, the specific form of the application client can also be different, for example, the application client can be a mobile phone client, a PC client, etc.

[0105] In order to further improve the uplink data rate, spectrum utilization, and uplink capacity, in this disclosure, the terminal device 101 supports dynamic switching of two sets of uplink transmitters between more than two frequency bands, such as between three or four frequency bands. The uplink transmitters of the terminal device 101 are dynamically switched between more than two frequency bands, i.e., the frequency band in which the uplink transmitters perform uplink transmission is dynamically switched between more than two frequency bands. In this disclosure, the terminal device 101 supports dynamic switching of two sets of uplink transmitters between more than two frequency bands, such as between three or four frequency bands. Figure 1In the embodiment, the terminal device 101 comprises an uplink transmitter 1 and an uplink transmitter 2, and both the uplink transmitter 1 and the uplink transmitter 2 can switch between the first frequency band to the fourth frequency band.

[0106] For example, the uplink transmitter 1 inputs a signal source, and after frequency multiplication, frequency mixing, filtering, amplification and other processes of the uplink transmitter 1, outputs a first frequency band signal; the uplink transmitter 2 inputs a signal source, and after frequency multiplication, frequency mixing, filtering, amplification and other processes of the uplink transmitter 2, also outputs a first frequency band signal, and the two first frequency band signals generated by the uplink transmitter 1 and the uplink transmitter 2 can be used for uplink transmission of one antenna port or two antenna ports. The antenna port is also referred to as a port. Each frequency band can include one or more carriers. The uplink transmission can be performed on one or more carriers of the first frequency band.

[0107] For example, the uplink transmitter 1 inputs a signal source, and after frequency multiplication, frequency mixing, filtering, amplification and other processes of the uplink transmitter 1, outputs a first frequency band signal; the uplink transmitter 2 inputs a signal source, and after frequency multiplication, frequency mixing, filtering, amplification and other processes of the uplink transmitter 2, also outputs a first frequency band signal, and the two first frequency band signals generated by the uplink transmitter 1 and the uplink transmitter 2 can be used for uplink transmission of one antenna port or two antenna ports. The antenna port is also referred to as a port. Each frequency band can include one or more carriers. The uplink transmission can be performed on one or more carriers of the first frequency band.

[0108] Since the uplink transmitter needs a switching interval when switching between different frequency bands, the terminal device 101 cannot perform uplink transmission in the switching interval, and therefore, it is necessary to know when the uplink transmitter of the terminal device 101 has switched, and then determine the switching interval.

[0109] Based on this, the scheme provided by the embodiments of the present application relates to communication and other technologies, and is a software program applied to a computer. The frequency band in which the uplink transmitter of the terminal device is located can be dynamically switched between more than two frequency bands. The antenna port state of the current uplink transmission and the antenna port state of the previous uplink transmission satisfy a preset condition. It is determined that the uplink transmitter of the terminal device has switched the uplink frequency band. There is a switching interval in which uplink transmission cannot be performed due to the switching of the transmitter. Therefore, the two sets of transmitters of the terminal device can be dynamically switched between more than two uplink frequency bands, the receiving performance of the uplink transmission is ensured, and the NR uplink rate, the spectrum utilization and the uplink capacity are improved. The specific implementation is described as follows:

[0110] The embodiment of the present disclosure provides an uplink transmitter switching method, which can be executed by any system with computing processing capability.

[0111] Figure 2 A flowchart of an uplink transmitter switching method provided by the embodiment of the present disclosure is shown. As shown in the figure, Figure 2 The uplink transmitter switching method provided by the embodiment of the present disclosure is applied to the network device side, and comprises the following steps:

[0112] S202, determine the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device, wherein the frequency band in which the uplink transmitter of the terminal device performs uplink transmission is dynamically switched between more than two frequency bands.

[0113] In the embodiment, the uplink transmitter of the terminal device has the capability that the frequency band in which the uplink transmitter performs uplink transmission can be dynamically switched between more than two frequency bands, and the capability can be transmitted by the terminal device to the network device through the capability information.

[0114] Since the network device cannot directly determine whether the uplink transmitter performs frequency band switching, the disclosure confirms the timing of the uplink transmitter frequency band switching through the change of the antenna port state of the current and previous uplink transmission.

[0115] S204, if the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device satisfy a preset condition, there is a switching interval for the frequency band switching of the uplink transmitter performing uplink transmission.

[0116] The preset condition of the embodiment is the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device which are pre-stored, which is used to compare the antenna port state of the uplink transmission with the pre-stored antenna port state to determine the timing of the uplink transmitter frequency band switching. It should be noted that when the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device satisfy the preset condition, it indicates that the uplink transmitter starts to perform frequency band switching, and there is a switching interval for the frequency band switching of the uplink transmitter performing uplink transmission, so that the uplink transmitter completes the switching of the frequency band in which the uplink transmitter performs uplink transmission between different frequency bands within the switching interval. When the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device do not satisfy the preset condition, it indicates that the uplink transmitter does not perform frequency band switching, and there is no need to set the switching interval, and the terminal device normally performs the uplink transmission of the terminal without uplink transmitter switching.

[0117] Exemplarily, the switching interval can be pre-configured by the network device through RRC signaling, or the switching interval can be reported by the terminal device, or it can be a pre-set fixed time interval, for example, 35μs, 140μs or 210μs. It should be noted that the switching interval is not less than the time length for the uplink transmitter to perform frequency band switching. The time length of the switching interval is not limited in the present application. For different situations that the frequency band in which the transmitter performing uplink transmission is switched when the uplink transmitter switching option is switched uplink, and the frequency band in which the transmitter performing uplink transmission is switched when the uplink transmitter switching option is dual uplink, the same length of switching interval can be used, or different lengths of switching interval can be used, which is not limited in the present application.

[0118] S206, cancel receiving the uplink information in the switching interval.

[0119] In this embodiment, according to the antenna port state of the uplink transmission of the terminal device, it is confirmed that the uplink transmitter of the terminal device starts to perform frequency band switching, and the network device cancels receiving the uplink information sent by the terminal device in the switching interval.

[0120] The uplink frequency band switching method provided by the embodiment of the present disclosure, the frequency band where the uplink transmitter of the terminal device is located can be dynamically switched between more than two frequency bands, the network device judges whether the antenna port state of the current uplink transmission and the antenna port state of the previous uplink transmission satisfy the preset condition, when the preset condition is satisfied, it is determined that the uplink transmitter of the terminal device switches the uplink frequency band, there is a switching interval in which the transmitter cannot perform uplink transmission, so that the uplink transmitter of the terminal device can be dynamically switched between more than two frequency bands, the receiving performance of the uplink transmission is guaranteed, and the NR uplink rate, spectrum utilization and uplink capacity are improved.

[0121] Figure 3 Another flowchart of the uplink transmitter switching method provided by the embodiment of the present disclosure is shown. As shown in Figure 3 The uplink transmitter switching method of the present embodiment includes steps S302 and steps S202-S206, that is, before determining the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device in step S202, the method further includes:

[0122] S302, sending uplink transmitter switching option configuration information to the terminal device, and configuring the uplink transmitter switching option (uplink Tx Switching Option) as switched uplink (switched UL) or dual uplink (dual UL).

[0123] Steps S202-S206 are the same as the embodiments of the above embodiments, which will not be described here.

[0124] It should be noted that the terminal device of the present disclosure has the capability of supporting two or more sets of uplink transmitters to perform uplink transmission on at least one carrier of one frequency band at the same time, that is, supporting switched uplink, and / or the terminal device has the capability of supporting two or more sets of uplink transmitters to perform uplink transmission on at least one carrier of each frequency band of different frequency bands at the same time, that is, supporting dual uplink. The uplink transmitter switching option is used to divide the above different capabilities of the terminal device. In the present disclosure, the terminal device supporting two sets of uplink transmitters is taken as an example for description, and for the case of the terminal device supporting more than two sets of uplink transmitters, adaptive modification can be made.

[0125] Exemplarily, the uplink transmitter switching option configuration information can be configured by the network device to the terminal device through RRC signaling. According to the capability of the terminal device, the uplink transmitter switching option configuration information sent by the network device configures the uplink transmitter switching option as switching uplink or dual uplink, thereby configuring different switching modes.

[0126] The uplink transmitter switching option of the embodiment is switching uplink, which is used to indicate that the terminal device supporting two sets of uplink transmitters can only perform uplink transmission on the carrier of one frequency band at the same time. The switching uplink can be used in the scenario of multi-carrier uplink transmission, such as multi-carrier uplink transmission containing supplementary uplink (SUL) carrier or inter-band carrier aggregation (CA) multi-carrier uplink transmission.

[0127] When the uplink transmitter switching option configuration information configures the uplink transmitter switching option as switching uplink, the terminal device supporting two sets of uplink transmitters can only perform uplink transmission on the carrier of one frequency band at the same time. In the present disclosure, the case of uplink transmission of the terminal device on the carrier of three frequency bands or four frequency bands is given.

[0128] It should be noted that for the case of uplink transmission of the terminal device supporting two sets of uplink transmitters on the carrier of more than two frequency bands, the mode can be adaptively modified according to the mode of the embodiment of the present disclosure, which is also within the protection scope of the present application.

[0129] Table 1 shows the possible cases of the state of two sets of uplink transmitters of the terminal device and the state of uplink transmission antenna ports among three frequency bands under the switching uplink scenario. The number of uplink transmitters on different frequency bands and the number of uplink transmission antenna ports on the corresponding frequency band are used to represent the state of the uplink transmitters of the terminal device and the state of the uplink antenna ports.

[0130] Table 1

[0131]

[0132] As shown in Table 1, under the switching uplink scenario, the state of two sets of uplink transmitters among three frequency bands includes three cases, that is, the number of uplink transmitters of one frequency band is two sets, and the number of uplink transmitters of the other frequency bands is 0, and correspondingly, the number of uplink transmission antenna ports of one frequency band is divided into two cases, that is, the number of uplink transmission antenna ports of the frequency band is two or one.

[0133] Table 2 shows the possible cases of the state of two sets of uplink transmitters of the terminal device and the state of uplink transmission antenna ports among four frequency bands under the switching uplink scenario.

[0134] Table 2

[0135]

[0136] As shown in Table 2, in the switching uplink case, the state of the two sets of uplink transmitters among the four frequency bands includes four cases, that is, the number of uplink transmitters in one frequency band is two sets, and the number of uplink transmitters in other frequency bands is 0. Correspondingly, the number of antenna ports for uplink transmission in one frequency band is divided into two cases, that is, the number of antenna ports for uplink transmission in the frequency band is two or one.

[0137] In Table 1 or Table 2, if the uplink transmitter state of the current uplink transmission and the previous uplink transmission belongs to different cases, the terminal device needs to perform uplink transmitter switching, and needs a switching interval for uplink transmitter switching of the terminal device, and the terminal device cannot perform uplink transmission in the switching interval. If the current state of the uplink transmitter of the terminal device is that the number of uplink transmitters in the first frequency band among the three frequency bands or the four frequency bands is 2T, and the number of uplink transmitters in the remaining frequency bands is 0T, when the next uplink transmission is performed, the state of the uplink transmitter of the terminal device is uplink transmission on at least one carrier in the second frequency band among the remaining frequency bands, then the uplink transmitter of the terminal device performs frequency band switching, and the state of the uplink transmitter after switching is that the number of uplink transmitters in the second frequency band is 2T, and the number of uplink transmitters in other frequency bands is 0T. For example, when the frequency band in which the uplink transmitter of the terminal device performs uplink transmission is switched among the three frequency bands, the first frequency band is frequency band A, and the second frequency band is frequency band B, then the state of the transmitter is switched from case 1 to case 2.

[0138] Since the network device (such as a base station) determines the uplink transmitter state by the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform uplink transmission due to uplink transmitter switching can be: when the terminal device performs uplink transmission on at least one carrier in a certain frequency band by one port or two ports, and the previous uplink transmission of the terminal device is one port or two port uplink transmission on at least one carrier in another frequency band, then the terminal device does not perform uplink transmission on any carrier in any frequency band in the switching interval.

[0139] Figure 4 A flowchart of the switching uplink uplink transmitter switching method provided by the embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure, step S204 is further refined into steps S402-S406. As shown in the embodiment of the present disclosure, Figure 3 the method comprises steps S202, S206, S302, and S402-S406, specifically comprising: Figure 4 S302, sending uplink transmitter switching option configuration information to the terminal device, the uplink transmitter switching option configuration information configuring the uplink transmitter switching option as switching uplink;

[0140]

[0141] ​S402, the preset condition is that: the antenna port state of the current uplink transmission of the terminal device is one-port or two-port uplink transmission on at least one carrier of a target frequency band, and the antenna port state of the previous uplink transmission of the terminal device is one-port or two-port uplink transmission on at least one carrier of a first frequency band,

[0142] and the antenna port state of the previous uplink transmission of the terminal device is one-port or two-port uplink transmission on at least one carrier of a first frequency band,

[0143] wherein the target frequency band and the first frequency band are different frequency bands in more than two frequency bands;

[0144] S404, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0145] S406, if the preset condition is not met, no switching interval for uplink transmitter switching needs to be set.

[0146] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, and will not be described here.

[0147] In one embodiment, when the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device do not meet the preset condition, it is determined that the frequency band switching of the uplink transmitter of the terminal device does not occur, at this time, no switching interval for uplink transmitter switching needs to be set, and the uplink transmission of the terminal without uplink transmitter switching is normally performed.

[0148] The uplink transmitter switching method provided by the embodiments of the present disclosure establishes the correspondence between the state of the uplink transmitter of the terminal device in more than two frequency bands and the possible situation of the uplink transmission antenna port, so as to determine whether the antenna port state of the current uplink transmission and the antenna port state of the previous uplink transmission meet the preset condition according to the correspondence, when the preset condition is met, it is determined that the uplink transmitter of the terminal device switches the uplink frequency band, and there is a switching interval in which the uplink transmission cannot be performed due to transmitter switching, thereby realizing that the uplink transmitter of the terminal device can be dynamically switched between more than two frequency bands, ensuring the reception performance of the uplink transmission, and further improving the NR uplink data rate, spectrum utilization and uplink capacity.

[0149] In one embodiment, before determining the antenna port state of the current uplink transmission of the terminal device and the antenna port state of the previous uplink transmission of the terminal device in step S202, the method further comprises:

[0150] determining the initial state of the antenna port of the uplink transmission of the terminal device, the initial state being uplink transmission supported by two ports on at least one carrier of a preset frequency band, the preset frequency band being a frequency band in more than two frequency bands.

[0151] The initial state of the antenna port of the uplink transmission is used to determine whether the initial uplink transmission needs to set the switching interval after the uplink transmitter switching option configuration is configured to switch the uplink. In the case of configuring to switch the uplink, the initial state is taken as the antenna port state of the terminal device in the last uplink transmission as part of the preset condition to determine whether the current state of the terminal device and the antenna port state of the last uplink transmission meet the preset condition, so as to judge whether there is a switching interval that cannot be used for uplink transmission due to transmitter switching, so that the uplink transmitter of the terminal device can be dynamically switched between more than two frequency bands, and the receiving performance of the uplink transmission is ensured.

[0152] It should be noted that the preset frequency band can be determined according to actual conditions, and the present application does not make specific limitations.

[0153] The preset frequency band of the embodiment is pre-configured in the protocol or configured to the terminal device by the network device, so that the network device determines whether the initial uplink transmission of the terminal device needs to set the switching interval for the frequency band switching of the uplink transmitter.

[0154] The uplink transmitter switching option is dual uplink, which is used to indicate that the terminal device with two sets of uplink transmitters supports simultaneous uplink transmission on carriers of different frequency bands. The dual uplink can be used in the multi-carrier uplink transmission scenario including inter-frequency CA multi-carrier uplink transmission.

[0155] When the uplink transmitter switching option configuration information configures the uplink transmitter switching option as dual uplink, the terminal device with two sets of uplink transmitters supports simultaneous uplink transmission on carriers of different frequency bands. Table 3 shows the possible cases of the state of the uplink transmitter of the terminal device in three frequency bands and the uplink transmission antenna port state in the dual uplink scenario, and the number of uplink transmitters in the frequency band and the number of uplink transmission antenna ports are used to represent the state of the uplink transmitter of the terminal device in three frequency bands and the uplink transmission antenna port state.

[0156] Table 3

[0157]

[0158] As shown in Table 3, in the dual uplink scenario, the state of the two sets of uplink transmitters in three frequency bands includes six cases, of which three cases are that the number of uplink transmitters in a certain frequency band is two sets and the number of uplink transmitters in the other frequency bands is 0, and correspondingly, the number of uplink transmission antenna ports in one frequency band is divided into two cases, i.e. the number of uplink transmission antenna ports in the frequency band is two or one, which corresponds to cases 1-3 in Table 3. The other three cases are that the number of uplink transmitters in two of the above frequency bands is 1T respectively, and the number of uplink transmitters in the remaining one frequency band is 0, and correspondingly, the number of uplink transmission antenna ports in at least one of the above two frequency bands is one, and the number of uplink transmission antenna ports in the remaining one frequency band is zero.

[0159] Table 4 shows the possible cases of the uplink transmitter state of the terminal device in the four frequency bands and the uplink transmission antenna port.

[0160] Table 4

[0161]

[0162]

[0163] As shown in Table 4, in the dual uplink case, the uplink transmitter state of the two sets of uplink transmitters in the four frequency bands includes ten cases, wherein four cases are that the number of uplink transmitters in one frequency band is 2T and the number of uplink transmitters in the other frequency bands is 0, and the number of uplink transmission antenna ports in the frequency band is divided into two cases, i.e., the number of uplink transmission antenna ports in the frequency band is two or one, as shown in cases 1-4 in Table 4; the remaining six cases are that the number of uplink transmitters in two of the frequency bands is one set respectively and the number of uplink transmitters in the remaining two frequency bands is 0, and the number of uplink transmission antenna ports in at least one of the two frequency bands is one and the number of uplink transmission antenna ports in the remaining two frequency bands is 0, as shown in cases 5-10 in Table 4.

[0164] In Table 3 and Table 4, if the uplink transmitter state of the current uplink transmission and the previous uplink transmission belongs to different cases, the terminal device needs to perform uplink transmitter switching, and needs a switching interval for the uplink transmitter switching of the terminal device, and the terminal device cannot perform uplink transmission in the switching interval.

[0165] For the first case of the uplink transmitter performing frequency band switching in the dual uplink case, if the current state of the terminal device is that the number of uplink transmitters in a first frequency band of more than two frequency bands is 2T and the number of uplink transmitters in the remaining frequency bands is 0T, for example, case 1 in Table 3 or Table 4, when the next uplink transmission, the state of the terminal device is to perform uplink transmission on two ports of at least one carrier in a second frequency band of the remaining frequency bands, for example, case 2 in Table 3 or Table 4, the uplink transmitter of the terminal device performs frequency band switching, and the uplink transmitter state of the terminal device after switching is that the number of uplink transmitters in the second frequency band is 2T and the number of uplink transmitters in the remaining frequency bands is 0T.

[0166] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device through the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform uplink transmission due to the uplink transmitter switching can be: when the terminal device performs uplink transmission of two ports on at least one carrier of a certain frequency band, and the previous uplink transmission of the terminal device is uplink transmission of one port or two ports on at least one carrier of another frequency band, the terminal device does not perform uplink transmission on a carrier of any frequency band in the switching interval.

[0167] For this case, Figure 5 A flow chart of a dual-uplink uplink transmitter switching method provided by an embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure, Figure 3 the step S204 is further refined, as shown in Figure 5 the method comprises steps S202, S206, S302 and S502-S506, and specifically, the method comprises:

[0168] S302, sending uplink transmitter switching option configuration information to the terminal device, the uplink transmitter switching option configuration information configuring the uplink transmitter switching option as dual-uplink;

[0169] S502, the preset condition is that the antenna port state of the current uplink transmission of the terminal device is uplink transmission of two ports on at least one carrier of a target frequency band,

[0170] and the antenna port state of the previous uplink transmission of the terminal device is uplink transmission of one port or two ports on at least one carrier of a first frequency band,

[0171] wherein the target frequency band and the first frequency band are different frequency bands greater than two frequency bands;

[0172] S504, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0173] S506, if the preset condition is not met, there is no need to set a switching interval for uplink transmitter switching.

[0174] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, and will not be described here again.

[0175] For the second case of the uplink transmitter frequency band switching of the dual uplink case, if the current state of the terminal device is in the first frequency band of more than two frequency bands, the number of uplink transmitters is 2T, and the number of uplink transmitters in the remaining frequency bands is 0T, for example, case 1 in Table 3 or Table 4; when the next uplink transmission, the state of the terminal device is to perform one-port uplink transmission on at least one carrier of each of two frequency bands of more than two frequency bands, for example, 1P in different frequency bands in case 4 to case 6 in Table 3 or case 5 to case 10 in Table 4, then the uplink transmitter of the terminal device performs frequency band switching, and the state of the uplink transmitter of the terminal device after switching is that the number of uplink transmitters in the above two frequency bands is 1T respectively, and the number of uplink transmitters in the remaining frequency bands is 0T.

[0176] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device through the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform uplink transmission due to the uplink transmitter switching can be: when the terminal device will perform one-port uplink transmission on at least one carrier of the first frequency band and will perform one-port uplink transmission on at least one carrier of the second frequency band, and the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of a certain frequency band and the state of the terminal device is to support two-port uplink transmission on this frequency band, or the previous uplink transmission of the terminal device is two-port uplink transmission on at least one carrier of a certain frequency band, then the terminal device does not perform uplink transmission on any carrier within the switching interval.

[0177] For the second case, Figure 6 A flow chart of a dual uplink uplink transmitter switching method provided by another embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure Figure 3 , step S204 is further refined as S602-S606, as shown in Figure 6 , the method comprises steps S202, S206, S302 and S602-S606, specifically, the method comprises:

[0178] S302, sending uplink transmitter switching option configuration information to the terminal device, and the uplink transmitter switching option configuration information configures the uplink transmitter switching option as dual uplink;

[0179] S602, the preset condition is that the current antenna port state of the terminal device for uplink transmission is one-port uplink transmission on at least one carrier of the first frequency band and one-port uplink transmission on at least one carrier of the second frequency band, wherein the first frequency band and the second frequency band are different frequency bands in more than two frequency bands;

[0180] and the antenna port state of the terminal device in the last uplink transmission is one-port uplink transmission on at least one carrier in one of the more than two frequency bands and the terminal device supports two-port uplink transmission on the one frequency band;

[0181] or, and the antenna port state of the terminal device in the last uplink transmission is two-port uplink transmission on at least one carrier in one of the more than two frequency bands;

[0182] S604, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0183] S606, if the preset condition is not met, there is no need to set a switching interval for uplink transmitter switching.

[0184] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, which will not be described here.

[0185] The antenna port state of the terminal device in the last uplink transmission in the one of the more than two frequency bands in the embodiment can be the same as or different from the first frequency band or the second frequency band, which is not limited in the present application.

[0186] For the third case of frequency band switching of the uplink transmitter in the dual uplink case, if the current state of the terminal device is that the number of uplink transmitters in the first frequency band of the more than two frequency bands is 2T and the number of uplink transmitters in the remaining frequency bands is 0T, for example, case 1 in Table 3 or Table 4; when the next uplink transmission, the state of the terminal device is one-port uplink transmission on at least one carrier in the second frequency band of the remaining frequency bands of the more than two frequency bands, and there is no uplink transmission on other frequency bands, then the uplink transmitter of the terminal device performs frequency band switching, and the uplink transmitter of the terminal device after switching includes two states, one state is that the number of uplink transmitters in the first frequency band is 1T, the number of uplink transmitters in the second frequency band is 1T, and the number of uplink transmitters in other frequency bands is 0T, for example, case 4 in Table 3 or case 5 in Table 4; the other state is that the number of uplink transmitters in the second frequency band is 2T, and the number of uplink transmitters in other frequency bands is 0T, for example, case 2 in Table 3 or case 2 in Table 4.

[0187] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device through the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform uplink transmission due to the uplink transmitter switching can be: when the terminal device currently performs uplink transmission of one port on at least one carrier of a certain frequency band, and the previous uplink transmission of the terminal device is uplink transmission of one port on at least one carrier of another frequency band and the state of the terminal device is that the terminal device supports uplink transmission of two ports on this frequency band, or and the previous uplink transmission of the terminal device is uplink transmission of two ports on at least one carrier of another frequency band, the terminal device does not perform uplink transmission on any carrier in the switching interval.

[0188] For the third case, Figure 7 A flow chart of a dual-uplink uplink transmitter switching method provided by another embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure, Figure 3 the step S204 is further refined into S702-S706, as shown in Figure 7 the method comprises steps S202, S206, S302 and S702-S706, and specifically, the method comprises:

[0189] S302, sending uplink transmitter switching option configuration information to the terminal device, the uplink transmitter switching option configuration information configuring the uplink transmitter switching option as dual-uplink;

[0190] S702, the preset condition is that the antenna port state of the current uplink transmission of the terminal device is uplink transmission of one port on at least one carrier of a target frequency band;

[0191] and the antenna port state of the previous uplink transmission of the terminal device is uplink transmission of one port on at least one carrier of a first frequency band and the terminal device supports uplink transmission of two ports on the first frequency band;

[0192] or, and the antenna port state of the previous uplink transmission of the terminal device is uplink transmission of two ports on at least one carrier of the first frequency band,

[0193] wherein the target frequency band and the first frequency band are different frequency bands in more than two frequency bands;

[0194] S704, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0195] S706, if the preset condition is not met, there is no need to set a switching interval for uplink transmitter switching.

[0196] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, and will not be described here.

[0197] For the fourth case of the band switching of the uplink transmitter in the dual uplink scenario. If the current state of the terminal device is that the uplink transmitter number is 1T in the first and second bands of the more than two bands, and the uplink transmitter number is 0T in the rest of the bands, for example, case 4 in Table 3 and case 5 in Table 4; when the next uplink transmission is performed, the state of the terminal device is that the uplink transmission of two ports in a certain band is performed, for example, case 1-case 3 in Table 3 and case 1-case 4 in Table 4, then the uplink transmitter of the terminal device is switched, and after the switching, the state of the uplink transmitter of the terminal device is that the uplink transmitter number is 2T in the band, and the uplink transmitter number is 0T in the rest of the bands.

[0198] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device through the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform the uplink transmission due to the uplink transmitter switching can be that when the terminal device is to perform the uplink transmission of two ports in at least one carrier of a certain band, and the previous uplink transmission of the terminal device is performed in at least one carrier of another band, the terminal device does not perform the uplink transmission in any carrier in the switching interval. When the terminal device is to perform the uplink transmission of two ports in at least one carrier of a certain band, and the previous uplink transmission of the terminal device is performed in at least one carrier of each of two bands, the terminal device does not perform the uplink transmission in any carrier in the switching interval. Or, when the terminal device is to perform the uplink transmission of two ports in at least one carrier of a certain band, and the previous uplink transmission of the terminal device is performed in at least one carrier of the same band, and the state of the terminal device is that the uplink transmission of two ports is not supported in the same band, the terminal device does not perform the uplink transmission in any carrier in the switching interval. Or, the manner of determining the switching interval in which the terminal device cannot perform the uplink transmission due to the uplink transmitter switching can be that when the terminal device is to perform the uplink transmission of two ports in at least one carrier of a certain band, and the previous uplink transmission of the terminal device is performed in at least one carrier of at least one of two bands, and the terminal device supports the uplink transmission of one port in each of the two bands, the terminal device does not perform the uplink transmission in any carrier in the switching interval.

[0199] For the fourth case, Figure 8 A flow chart of a dual uplink uplink transmitter switching method provided by another embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure, Figure 3 the step S204 is further refined into S802-S806, as shown in Figure 8As shown, the method comprises steps S202, S206, S302 and S802-S806, and specifically, the method comprises:

[0200] S302, sending the uplink transmitter switching option configuration information to the terminal device, wherein the uplink transmitter switching option configuration information configures the uplink transmitter switching option as dual uplink;

[0201] S802, the preset condition is that the antenna port state of the current uplink transmission of the terminal device is two-port uplink transmission on at least one carrier of the target frequency band,

[0202] and the antenna port state of the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of the first frequency band and one-port uplink transmission on at least one carrier of the second frequency band, wherein at least one of the first frequency band and the second frequency band is different from the target frequency band, and the target frequency band, the first frequency band and the second frequency band are more than two frequency bands;

[0203] or, the antenna port state of the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of the third frequency band, wherein the target frequency band and the third frequency band are different frequency bands in more than two frequency bands;

[0204] or, and the antenna port state of the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of the target frequency band, and the terminal device does not support two-port uplink transmission on the target frequency band;

[0205] S804, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0206] S806, if the preset condition is not met, there is no need to set the switching interval for uplink transmitter switching.

[0207] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, which will not be described here.

[0208] For the fifth case of the uplink transmitter frequency band switching in the dual uplink case. If the current state of the terminal device is that the uplink transmitter numbers in the first frequency band and the second frequency band are 1T respectively, and the uplink transmitter numbers in the rest of the frequency bands are 0T, for example, case 4 in Table 3 and case 5 in Table 4; when the next uplink transmission is performed, the state of the terminal device is that the uplink transmission is performed on at least one carrier of the third frequency band of the more than two frequency bands, and no uplink transmission is performed on the other frequency bands, then the uplink transmitter of the terminal device performs the frequency band switching, and the uplink transmitter state of the terminal device after the switching includes three kinds, the first kind is that the uplink transmitter numbers in the second frequency band and the third frequency band are 1T respectively, and the uplink transmitter numbers in the rest of the frequency bands are 0T, for example, case 6 in Table 3 and case 8 in Table 4; the second kind is that the uplink transmitter numbers in the first frequency band and the third frequency band are 1T respectively, and the uplink transmitter numbers in the rest of the frequency bands are 0T, for example, case 5 in Table 3 and case 6 in Table 4; the third kind is that the uplink transmitter number in the third frequency band is 2T, and the uplink transmitter numbers in the rest of the frequency bands are 0T, for example, case 3 in Table 3 and case 3 in Table 4.

[0209] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device by the antenna port state of the uplink transmission, the manner of determining the switching interval in which the terminal device cannot perform the uplink transmission due to the uplink transmitter switching can be that when the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier in at least one frequency band of the first frequency band and the second frequency band, and the state of the terminal device is that the first frequency band and the second frequency band support one-port uplink transmission, and the current uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of the third frequency band, and no uplink transmission is performed on the first frequency band and the second frequency band, then the terminal device does not perform the uplink transmission on any carrier in the switching interval.

[0210] For the fifth case, Figure 9 A flow chart of a dual uplink uplink transmitter switching method provided by another embodiment of the present disclosure is shown. Based on the embodiment of the present disclosure, Figure 3 The embodiment further refines step S204 to S902-S906, as shown in Figure 9 The method includes steps S202, S206, S302 and S902-S906, and specifically, the method includes:

[0211] S302, the uplink transmitter switching option configuration information configures the uplink transmitter switching option as dual uplink;

[0212] S902, the preset condition is that the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier in at least one frequency band of the first frequency band and the second frequency band, and the first frequency band and the second frequency band support one-port uplink transmission of the terminal device;

[0213] and the antenna port state of the current uplink transmission of the terminal device is one-port uplink transmission on at least one carrier of the third frequency band, and there is no uplink transmission on the first frequency band and the second frequency band,

[0214] wherein the first frequency band, the second frequency band and the third frequency band are different frequency bands in the more than two frequency bands;

[0215] S904, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0216] S906, if the preset condition is not met, there is no need to set a switching interval for uplink transmitter switching.

[0217] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, and will not be described here.

[0218] For the sixth case of frequency band switching of the uplink transmitter in the dual uplink case. If the current state of the terminal device is that the number of uplink transmitters in the first frequency band and the second frequency band in the more than two frequency bands is 1T respectively, and the number of uplink transmitters in the remaining frequency bands is 0T; when the next uplink transmission, the state of the terminal device is that one-port uplink transmission is performed on at least one carrier of each of the two frequency bands in the more than two frequency bands, and at least one of the two frequency bands is a frequency band different from the first frequency band and the second frequency band, then the uplink transmitter of the terminal device performs frequency band switching, and the state of the uplink transmitter of the terminal device after switching is that the number of uplink transmitters in the two frequency bands is 1T respectively.

[0219] Since the network device (such as a base station) determines the uplink transmitter state of the terminal device by the antenna port state of the uplink transmission, the way to determine the switching interval in which the terminal device cannot perform uplink transmission due to uplink transmitter switching can be: when the previous uplink transmission of the terminal device is one-port uplink transmission on at least one carrier in at least one frequency band of the first frequency band and the second frequency band, and the state of the terminal device is that one-port uplink transmission is supported on the first frequency band and the second frequency band, and the current state of the terminal device is that there is one-port uplink transmission on at least one carrier of each of the two frequency bands, and at least one of the two frequency bands is a frequency band different from the first frequency band and the second frequency band, then the terminal device does not perform uplink transmission on any carrier within the switching interval.

[0220] For the sixth case, Figure 10 A flow chart of a dual uplink uplink transmitter switching method provided by another embodiment of the present disclosure is shown. This embodiment further refines step S204 to S1002-S1006 on the basis of Figure 3 . Figure 10As shown, the method comprises steps S202, S206, S302 and S1002-S1006, and specifically, the method comprises:

[0221] S302, the uplink transmitter switching option configuration information configures the uplink transmitter switching option as dual uplink;

[0222] S1002, the preset condition is that the antenna port state of the terminal device in the previous uplink transmission is one-port uplink transmission on at least one carrier in at least one of the first frequency band and the second frequency band, and the terminal device supports one-port uplink transmission in the first frequency band and the second frequency band;

[0223] and the antenna port state of the terminal device in the current uplink transmission is one-port uplink transmission on at least one carrier in the first target frequency band and one-port uplink transmission on at least one carrier in the second target frequency band, at least one of the first target frequency band and the second target frequency band is a different frequency band from the first frequency band and the second frequency band,

[0224] wherein the first frequency band, the second frequency band, the first target frequency band, and the second target frequency band are greater than two frequency bands;

[0225] S1004, if the preset condition is met, there is a switching interval for uplink transmitter switching;

[0226] S1006, if the preset condition is not met, there is no need to set a switching interval for uplink transmitter switching.

[0227] It should be noted that steps S202 and S206 are the same as the foregoing embodiments, and will not be described here.

[0228] In one embodiment of the present disclosure, before determining the antenna port state of the terminal device in the current uplink transmission and the antenna port state of the terminal device in the previous uplink transmission in step S202, the method further comprises:

[0231] or, the initial state is to support one-port uplink transmission on two preset frequency bands respectively, and the two preset frequency bands are greater than two frequency bands.

[0232] The initial state of the antenna port of the uplink transmission of the embodiment is used to determine whether a switching interval needs to be set after the uplink transmitter switching option is configured as dual uplink. In the case of being configured as dual uplink, the initial state is taken as the antenna port state of the terminal device in the last uplink transmission as part of the preset condition, so as to determine whether the current state of the terminal device and the antenna port state of the last uplink transmission meet the preset condition, so as to judge whether there is a switching interval in which the uplink transmission cannot be performed due to transmitter switching, so that the uplink transmitter of the terminal device can be dynamically switched between more than two frequency bands, and the receiving performance of the uplink transmission is ensured. It should be noted that the preset frequency band can be determined according to actual conditions, and the present application does not make specific limitations.

[0233] The preset frequency band of the embodiment is pre-configured in the protocol or configured to the terminal device by the network device, so that the network device determines whether the initial uplink transmission of the terminal device needs to set a switching interval for the uplink transmitter to switch the frequency band.

[0234] The uplink transmitter switching method provided by the embodiment of the present disclosure establishes the correspondence between the state of the uplink transmitter of the terminal device in more than two frequency bands and the possible case of the uplink transmission antenna port state, so as to judge whether the antenna port state of the current uplink transmission and the antenna port state of the last uplink transmission meet the preset condition according to the correspondence, when the preset condition is met, it is determined that the uplink transmitter of the terminal device switches the uplink frequency band, and there is a switching interval in which the uplink transmission cannot be performed due to transmitter switching, so that the uplink transmitter of the terminal device can be dynamically switched between more than two frequency bands, the receiving performance of the uplink transmission is ensured, and the NR uplink data rate, spectrum utilization and uplink capacity are further improved.
