[0176] FIG1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0177] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited to these.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0180] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0181] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0182] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of the subjects are arbitrary, and the subjects may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

[0183] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0184] In some implementations, there are some restrictions on uplink multi-carriers, for example: a 2Tx (2 Transmitter / 2 antennas / 2 transmission links / 2 transmission ports) UE (User Equipment) can be configured with up to 2 UL (Up-Link) frequency bands, and the UL frequency band is adjusted through RRC (Radio Resource Control) reconfiguration, and a 2Tx UE (i.e., a terminal with 2 antennas / a terminal with 2 Transmitters / a terminal with 2 transmission links) can only switch antennas between 2 UL frequency bands. Dynamically selecting carriers through uplink antenna switching, for example, based on data traffic, TDD (Time Division Duplex) configuration, bandwidth of the frequency band, and channel conditions, can achieve better uplink data rates, spectrum utilization, and uplink capacity. Therefore, in this embodiment, the 2Tx UE can be configured with more than two UL frequency bands, and supports uplink antenna switching on 3band (frequency band) and / or 4band, introducing new switching cases such as switching from band1+band2 (1Tx+1Tx) to band3+band4 (1Tx+1Tx), and switching from band1+band2 (1Tx+1Tx) to band3 (2Tx).

[0185] In some implementations, RAN4 (Radio Access Network 4) can support 3Tx UE (terminal with 3 antennas, terminal with 3 Transmitters, terminal with 3 transmission links), and simultaneously support 2-port transmission on one band and 1-port transmission on another band, that is, one of the two bands needs to support 2Tx (2 antennas, 2 Transmitters, 2 transmission links) MIMO (Multiple Input Multiple Output, using multiple antennas to simultaneously send and receive multiple data streams on the same channel to increase the data transmission rate).

[0186] In some implementations, during the interaction between the terminal and the network device, the relevant parameters for configuring the number of antennas for uplink antenna switching mainly include uplinkTxSwitching2TMode (2-antenna uplink transmission switching mode), which is used to indicate that the terminal supports the antenna switching scenario of 2Tx switching to 2Tx; uplinkTxSwitching-DualUL-TxState (dual uplink switching transmission state), with the values ​​of oneT and twoT, which are used to indicate whether the antenna switched by the terminal is Tx1 or Tx2.

[0187] In some embodiments, the configuration of related bands can be configured for each band. When a band is not configured with a related band, when it is indicated with oneT, 2Tx is still switched to this band. When oneT is supported, a band is configured with related bands, and the final switching of Tx needs to be on this band and its related bands. For example: when the 1P port transmission on bandC is scheduled, and Tx is currently associated with band A and band B, the Tx associated with bandB is switched to bandC, while the other Tx associated with bandA remains unchanged; when the 1P port transmission on bandD is scheduled, and Tx is currently associated with bandA and bandB, the Tx associated with bandA (band B) is switched to bandD, while the other Tx associated with bandB (or bandA) is switched to bandC.

[0188] In the above implementation, if the previous transmission is 1P transmission on band A, and another Tx points to band B, the next transmission indicated is 1P transmission on band C. The network device will configure the RRC signaling of oneT and twoT to indicate the switching case used to indicate the number of antennas to be switched. In the scenario of 2Tx UE, when the next transmission is 2P transmission on band C, there will be no ambiguity. However, in the scenario of 3Tx UE, there will be ambiguity.

[0189] In addition, considering the different situations of UE's support for concurrent bands, some implicit methods need to be set to avoid ambiguity. For example, the existing mechanism indicates oneT, but actually switches to 2Tx. Considering the UE with 3Tx (3 antennas, 3 transmitters, 3 transmission links), there is a situation where the instruction oneT actually switches to threeT, or the instruction twoT actually switches to threeT.

[0190] FIG2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0191] Step S2101 , the terminal 101 sends first capability information to the network device 102 .

[0192] In some implementations, the network device 102 receives first capability information.

[0193] In some implementations, the first capability information is used to indicate that the terminal supports switching between M uplink antennas and / or that the terminal supports switching from M uplink antennas to M antennas, where the switching is uplink transmission switching on multiple frequency bands, where the multiple frequency bands are frequency band combinations supported by the terminal, and where M is an integer greater than or equal to 3. It should be noted that, in this embodiment, switching between M uplink antennas can be described as switching between M Txs, for example, switching between three uplink antennas can be described as switching between 3Txs.

[0194] For example, this embodiment is applied to a communication system as shown in FIG1 , which includes a network device 102 and a terminal 101. The terminal 101 is configured with M antennas, where M is an integer greater than or equal to 3. The M antennas are uplink transmission antennas, and the terminal 101 implements uplink transmission with the network device 102 based on the M antennas. During the uplink transmission process of the terminal 101, when the current uplink transmission antenna may not meet the transmission requirements due to interference from environmental factors or other signals, it is necessary to switch the uplink transmission antenna. The switching indication information sent by the network device 102 indicates that the terminal 101 is switched from the current uplink antenna to other uplink antennas of the M antennas to avoid uplink transmission obstacles caused by antenna signal congestion, or to switch the band pointed to by the current transmission antenna to other bands. It should be noted that the switching between the M uplink antennas in this embodiment indicates that the terminal is configured with M uplink antennas, and the switching between the M uplink antennas to the M antennas indicates that the terminal can perform multi-band frequency switching on the M uplink antennas.

[0195] This embodiment is applied to a terminal 101, which is provided with M uplink antennas, where M is an integer greater than or equal to 3. The terminal is provided with switching between the M uplink antennas and / or switching between the M uplink antennas to the M antennas based on the uplink antenna. The switching method is to perform uplink transmission switching on multiple frequency bands, where the multiple frequency bands are a combination of frequency bands supported by the terminal.

[0196] In some implementations, the uplink antenna is a channel for the terminal 101 to send uplink transmission signals. The name of the uplink antenna is not limited, and it may be, for example, "radio frequency link", "transmission link", "uplink antenna link", "uplink transmission link", etc.

[0197] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable.

[0198] In some embodiments, the name of the first capability information is not limited, and it may be, for example, "first indication information", "first reporting information", "antenna quantity information", "antenna switching capability information", etc.

[0199] In some embodiments, the names of information, etc. are not limited to the names recorded in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "code element", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0200] In some embodiments, terms such as "send", "transmit", "report", "send", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0201] In some embodiments, the method further includes: determining that the terminal 101 supports frequency band switching among M uplink antennas. For example, before reporting the first capability information, the terminal 101 needs to determine whether the terminal 101 supports frequency band switching among M uplink antennas based on its own configuration or related indication information. And when it is determined that the terminal 101 supports it, the first capability information for indicating the antenna switching capability of the terminal 101 is generated, wherein the first capability information is used to indicate that the terminal supports switching between M uplink antennas and / or switching between M uplink antennas to M antennas. For example, the terminal 101 can determine the uplink antenna configuration of the current terminal 101 by reading the factory configuration information, and when the terminal 101 meets the M uplink antenna configuration, it is determined that the terminal 101 supports frequency band switching among M uplink antennas.

[0202] In some implementations, the above step of “determining that the terminal 101 can perform frequency band switching in M ​​uplink antennas” includes:

[0203] A first parameter sent by a network device is received, where the first parameter is used to indicate that frequency band switching of M uplink antennas is configured in an inter-band uplink carrier aggregation link or a supplementary uplink.

[0204] According to the first parameter, it is determined that the terminal supports frequency band switching of M uplink antennas on the inter-band uplink carrier aggregation link or the supplementary uplink.

[0205] For example, in this embodiment, the first parameter sent by the network device 102 indicates that the frequency band switching of the M uplink antennas of the terminal 101 is configured in the inter-band uplink carrier aggregation link or the supplementary uplink. Among them, the first parameter can also be used to indicate the frequency band switching mode of the terminal 101 based on the M uplink antennas, and different frequency band switching modes have different switching methods on the M uplink antennas. The first parameter information is indicated to the terminal 101 by the network device 102 to indicate that the terminal 101 supports the switching mode of M uplink antennas in the inter-band UL CA (uplink carrier aggregation link) or SUL (Supplementary Uplink). After receiving the first parameter, the terminal 101 determines that the terminal 101 can support the frequency band switching in the M uplink antennas according to the first parameter.

[0206] In some implementations, the name of the first parameter is not limited, for example, "uplink mode parameter", "uplink transmission indication parameter", "antenna switching mode parameter", etc. For example, in this embodiment, M is 3, and the first parameter can be: uplinkTxSwitching3TMode (uplink transmission switching mode of 3 antennas), and the first parameter is used to indicate that the terminal 101 uses the 3T switching mode in uplink transmission.

[0207] In some implementations, the first capability information includes the second capability information.

[0208] In some implementations, the second capability information is used to indicate that M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink can perform frequency band switching, and the above-mentioned “sending the first capability information” includes:

[0209] Sending second capability information;

[0210] Based on the second capability information, it is determined that the terminal is capable of performing frequency band switching among M uplink antennas.

[0211] For example, in this embodiment, the terminal 101 sends the second capability information based on the configuration.

[0212] In some implementations, the second capability information is used to indicate that the terminal 101 supports frequency band switching for M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink. The terminal 101 may determine, based on the configuration information of the device, whether frequency band switching for M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink is supported in the terminal. When it is determined that the terminal 101 has the capability, the second capability information is generated. Based on the second capability information, it is determined that frequency band switching for M uplink antennas is supported in the terminal.

[0213] In some embodiments, the method further includes: determining that the terminal does not support frequency band switching of M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink. By way of example, in this embodiment, after the terminal 101 reports the first capability information, it can determine whether the terminal 101 supports frequency band switching of M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink according to relevant information configured by the base station or factory configuration information of the terminal 101. When the terminal 101 does not have the corresponding configuration or does not receive the configuration information sent by the network device 102, it is determined that the terminal 101 does not support frequency band switching of M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink.

[0214] In some implementations, the step of “determining that the terminal does not support frequency band switching on M uplink antennas” includes:

[0215] If it is determined that the terminal has not reported the second capability information, then the terminal does not support frequency band switching for M uplink antennas, and the second capability information is used to indicate support for frequency band switching for M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink.

[0216] For example, in this embodiment, the terminal 101 can determine whether the terminal 101 supports frequency band switching on M uplink antennas by reading the factory configuration information. When the terminal 101 determines that the terminal 101 does not support frequency band switching on M uplink antennas based on the factory configuration information, the second capability information is not reported, so that the network device 102 determines that the terminal 101 does not support frequency band switching on M uplink antennas. For example, the timing can be started after the network device 102 receives the first capability information sent by the terminal 101. When the timing time reaches the set threshold, the second capability information reported by the terminal 101 is not received, and it is determined that the terminal 101 does not support frequency band switching on M uplink antennas in the inter-band uplink carrier aggregation link or the supplementary uplink.

[0217] In some implementations, the step of “determining that the terminal does not support frequency band switching on M uplink antennas” includes:

[0218] The first parameter is not configured in the terminal, which determines that the terminal does not support frequency band switching in M ​​uplink antennas. The first parameter is used to indicate that the switching mode of the M uplink antennas is configured in the inter-band uplink carrier aggregation link or the supplementary uplink.

[0219] For example, in this embodiment, after the network device 102 receives the first capability information sent by the terminal 101, the antenna switching of the terminal 101 is configured according to the antenna switching capability of the terminal 101 and the current antenna switching requirement, and the first parameter is used to indicate that the terminal 101 can support M uplink antennas to switch in the inter-band uplink carrier aggregation link or the supplementary uplink in the current state. Therefore, timing can be performed after the terminal 101 sends the first capability information. When the timing time reaches the set threshold, it is determined that the terminal 101 does not support M uplink antennas to switch in the inter-band uplink carrier aggregation link or the supplementary uplink.

[0220] In some implementations, the method further includes: determining an antenna link status of the terminal.

[0221] For example, in this embodiment, after the terminal 101 reports the first capability information, in order to prevent ambiguity caused during the switching process, the antenna link status of the M antenna links of the current terminal 101 can be determined, and the frequency band switching between the M uplink antennas can be implemented based on the antenna link status. In this embodiment, the terminal 101 can identify the M antennas to determine the antenna link status of the M antennas. The network device 102 can also indicate to the terminal 101 the antenna link status that currently needs to be switched based on the first capability information sent by the terminal 101 and the switching requirement of the current antenna link, and the terminal 101 determines the antenna link status based on the indication information.

[0222] In some implementations, the above “determining the antenna link status of the terminal” includes:

[0223] receiving a second parameter sent by the network device, where the second parameter is used to indicate an antenna link state;

[0224] An antenna link state is determined according to the second parameter.

[0225] For example, in this embodiment, after the network device 102 receives the first capability information sent by the terminal 101, when it is determined based on the first capability information that under the current switching strategy, when the terminal 101 switches the antenna link state, an antenna switching ambiguity problem will occur, a second parameter can be configured for the terminal 101 based on the current network state and the first capability information of the terminal 101 to indicate the antenna link state of each antenna link in the terminal 101 in the current state. After receiving the second parameter, the terminal 101 determines the current antenna link state. The antenna link state is the band to which each of the M antennas in the terminal 101 points, or the band to which some of the M antennas point. The second parameter can be: uplink Tx Switching DualUL TxState atmost MTx (multi-link switching mode)

[0226] Optionally, determining the antenna link state according to the second parameter includes:

[0227] Determining that the terminal satisfies a first condition;

[0228] determining an antenna link state according to the second parameter;

[0229] The first condition includes one or more of the following:

[0230] When the terminal switches the uplink antenna based on the first parameter sent by the network device, there are multiple switching modes, wherein the first parameter is used to indicate the frequency band switching of the M uplink antennas;

[0231] After the terminal sends the second capability information, there are multiple switching modes when performing uplink antenna switching, wherein the second capability information is used to indicate that the terminal supports M uplink antennas for frequency band switching;

[0232] The terminal is configured for dual uplink transmission, which is used to indicate that the terminal supports simultaneous transmission of two frequency bands;

[0233] The terminal is configured for both uplink transmission, and both uplink transmission is used to indicate that the terminal supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band;

[0234] The terminal is configured for triple uplink transmission, which is used to indicate that the terminal supports simultaneous transmission in three frequency bands;

[0235] The terminal is configured for full uplink transmission, and the full uplink transmission is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0236] For example, in this embodiment, after receiving the second parameter sent by the network device 102, the terminal 101 determines the current state of the terminal 101 to determine whether the terminal 101 meets the first condition. The first condition includes one or more of the following:

[0237] The network device 102 sends a first parameter to instruct the terminal 101 to switch the frequency band on the M uplink antennas. After the terminal 101 receives the first parameter, when the switching requirement is met and the antenna is switched, there are multiple switching modes on the M uplink antennas, which will cause the switching ambiguity problem in the terminal 101. Therefore, the antenna link state of each antenna in the current state of the terminal 101 can be determined by the first parameter indicated by the network device, thereby avoiding the switching ambiguity problem. Among them, the first parameter includes the band information pointed to by each antenna.

[0238] After the terminal 101 sends the first capability information to the network device 102, it can determine whether it has the second capability based on the factory configuration information of the terminal 101. The second capability is the ability of the terminal to support M uplink antennas to switch frequency bands in an inter-band uplink carrier aggregation link or a supplementary uplink. When the terminal 101 determines that it supports the second capability, it reports the second capability information to the network device 102. After reporting the second capability information, when the terminal 101 switches the uplink antenna, there are multiple switching modes based on the M uplink antennas in the terminal 101, resulting in a switching ambiguity problem in the terminal 101. Therefore, at this time, it is necessary to determine the antenna link status of each antenna on the current M uplink antennas of the terminal 101.

[0239] The terminal 101 is configured for dual uplink transmission. When the terminal 101 switches M uplink antennas, a switching ambiguity problem may occur in the terminal 101. Dual uplink transmission uses two independent uplinks at the same time to send data in the terminal 101 to the two links in parallel for transmission, thereby improving transmission bandwidth and capacity and reducing data transmission delay.

[0240] Terminal 101 is configured for all uplink transmission, wherein all uplink transmission is used to indicate that the terminal 101 supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band on M antennas. Based on this configuration, when the terminal 101 switches the uplink antenna, it is impossible to determine which switching method to use to meet the current switching requirements, which can easily lead to switching ambiguity problems in the terminal 101. Therefore, in this state, it is necessary to indicate the antenna link status in the terminal 101 to determine the antenna link status of the terminal 101.

[0241] Terminal 101 is configured for three uplink transmissions, wherein the three uplink transmissions are used to indicate that three frequency bands are supported for simultaneous transmission on M antennas in terminal 101. Based on this configuration, when terminal 101 switches uplink antennas, it is impossible to determine how to configure the switching bands in the M uplink antennas, resulting in a switching ambiguity problem in terminal 101. Therefore, when terminal 101 is configured for three uplink transmissions, it is necessary to indicate the antenna link status in terminal 101 and determine the antenna link status of terminal 101.

[0242] The terminal is configured for full uplink transmission, and the full uplink transmission is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0243] Terminal 101 is configured for full uplink transmission, where full uplink transmission is used to indicate that terminal 101 supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band. At this time, the antenna link of terminal 101 supports multiple transmission modes. When terminal 101 switches uplink antennas, the switching frequency bands of each antenna cause switching ambiguity in terminal 101. Therefore, it is necessary to indicate the antenna link status in terminal 101.

[0244] Optionally, in some embodiments, the second parameter includes one or more of the following:

[0245] The second parameter is a first preset value, and the first preset value is used to indicate that an uplink antenna in the terminal supports the target frequency band;

[0246] The second parameter is a second preset value, and the second preset value is used to indicate that two uplink antennas in the terminal support the target frequency band;

[0247] The second parameter is a third preset value, and the third preset value is used to indicate that three uplink antennas in the terminal support the target frequency band.

[0248] For example, in this embodiment, the second parameter includes a target frequency band to which the terminal 101 needs to switch, and the second parameter is a first pre-value, wherein the first pre-value may be one T, which is used to indicate that there is one uplink antenna in the terminal 101 that supports the target frequency band; the second parameter is a second pre-value, wherein the second pre-value may be two T, which is used to indicate that there are two uplink antennas in the terminal 101 that support the target frequency band; the second parameter is a third pre-value, wherein the third pre-value may be three T, which is used to indicate that there are three uplink antennas in the terminal 101 that support the target frequency band.

[0249] In some embodiments, the above method further includes: receiving a third parameter sent by the network device, where the third parameter is used to indicate that the three uplink antennas in the terminal support multiple frequency bands.

[0250] For example, in this embodiment, the network device 102 sends a third parameter to indicate the antenna switching mode in the terminal 101, wherein the third parameter is used to indicate the multiple frequency bands supported by the three uplink antennas in the terminal. That is, after receiving the first capability information sent by the terminal 101, the network device 102 configures the third parameter indicating the switching mode for the terminal 101 based on the capability of the terminal 101, thereby indicating the multiple frequency bands supported by the three uplink antennas in the terminal 101.

[0251] Optionally, in some embodiments, the method further comprises:

[0252] Determining that the terminal satisfies the second condition;

[0253] Based on the third parameter, indicating that three uplink antennas in the terminal support multiple frequency bands;

[0254] The second condition includes one or more of the following:

[0255] When the terminal performs uplink antenna switching based on the first parameter sent by the network device, there are multiple switching modes, wherein the first parameter is used to indicate the frequency band switching between M uplink antennas and M antennas;

[0256] After the terminal sends the second capability information, there are multiple switching modes when performing uplink antenna switching, wherein the second capability information is used to indicate that the terminal supports M uplink antennas and M antennas simultaneously performing frequency band switching;

[0257] The terminal is configured for duplex transmission, which is used to indicate that the terminal supports simultaneous transmission in two frequency bands;

[0258] The terminal is configured for full-duplex transmission, which indicates that the terminal supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band;

[0259] The terminal is configured for triplex transmission, which is used to indicate that the terminal supports simultaneous transmission in three frequency bands;

[0260] The terminal is configured for full triplex transmission, which is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0261] For example, after receiving the third parameter fed back by the network device 102, the terminal 101 determines the current switching state of the terminal 101 to determine whether the terminal 101 meets the second condition, wherein the second condition includes one or more of the following:

[0262] When the terminal 101 receives the first parameter sent by the network device to switch the uplink antenna, if there are multiple switching methods based on the M uplink antennas in the terminal 101, the third parameter is used to indicate the multiple frequency bands supported by the three uplink antennas in the terminal, wherein the first parameter is used to indicate the switching mode between M uplink antennas and M antennas.

[0263] When the terminal 101 determines that it supports M uplink antennas for frequency band switching in an inter-band uplink carrier aggregation link or a supplementary uplink, the terminal 101 sends the second capability information to the network device 102. When the uplink antenna switching is performed after sending the second capability information, there are multiple switching modes in the terminal 101. The second parameter sent by the network device 102 is required to determine the antenna link status in the terminal 101.

[0264] Terminal 101 is configured for duplex transmission, wherein duplex transmission is used to indicate that terminal 101 supports simultaneous transmission in two frequency bands when performing antenna switching. At this time, if antenna switching is indicated in terminal 101, based on the configuration of duplex transmission, an antenna switching ambiguity problem will occur in terminal 101. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0265] Terminal 101 is configured for full-duplex transmission, wherein full-duplex transmission is used to indicate that the terminal supports simultaneous transmission in two frequency bands and separate transmission in a single frequency band. Based on the full-duplex transmission configuration in terminal 101, when performing antenna switching, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas in the current antennas are selected for frequency band switching, and the target frequency band to which the corresponding switched antennas need to be switched. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0266] Terminal 101 is configured for triplex transmission, wherein triplex transmission is used to indicate that terminal 101 supports simultaneous transmission in three frequency bands. Based on the triplex transmission configuration in terminal 101, when performing antenna switching, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas to select for frequency band switching. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0267] Terminal 101 is configured for full triplex transmission, wherein full triplex transmission is used to indicate that terminal 101 supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band. Based on the full triplex transmission configuration in terminal 101, when antenna switching is performed, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas are selected for frequency band switching. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0268] In some implementations, the above “determining the antenna link status of the terminal” includes:

[0269] receiving a fourth parameter sent by the network device, where the fourth parameter is used to instruct the terminal to point all frequency bands supported by the M uplink antennas to a target frequency band, where the target frequency band is a scheduled frequency band to be transmitted;

[0270] According to the fourth parameter, the frequency bands supported by the M uplink antennas of the terminal are all directed to the target frequency band.

[0271] For example, in this embodiment, the network device 102 indicates the antenna switching mode in the terminal 101 based on the first capability information sent by the terminal 101, generates a fourth parameter and sends it to the terminal 101, wherein the fourth parameter is used to instruct the terminal 101 to point all the frequency bands supported by the M uplink antennas to the target frequency band, which is the scheduled frequency band to be transmitted. The terminal 101 points all the frequency bands supported by the M uplink antennas to the target frequency band according to the fourth parameter.

[0272] Optionally, in some implementation modes, the above “pointing all frequency bands supported by M uplink antennas of the terminal to the target frequency band according to the fourth parameter” includes:

[0273] Determining that the terminal satisfies a third condition;

[0274] According to the fourth parameter, the frequency bands supported by the M uplink antennas of the terminal are all directed to the target frequency band;

[0275] The third condition includes one or more of the following:

[0276] The target frequency band is not configured with a related frequency band;

[0277] The target frequency band is not configured with a related frequency band group;

[0278] The target frequency band is scheduled for M-port transmission;

[0279] The target frequency band supports M-port transmission.

[0280] For example, in this embodiment, after receiving the fourth parameter, the terminal 101 determines the current state of the terminal 101 to determine whether the terminal 101 satisfies the third condition. When it is determined that the terminal 101 satisfies the third condition, according to the fourth parameter, the frequency bands supported by the M uplink antennas of the terminal 101 are all directed to the target frequency band, wherein the third condition includes one or more of the following:

[0281] A related frequency band that is not configured with a target frequency band among the target frequency bands indicated by the network device 102;

[0282] The target frequency band instructed to be switched by the network device 102 does not have a frequency band group associated with the target frequency band configured;

[0283] The target frequency band indicated by the network device 102 needs to be transmitted simultaneously through the M-port process;

[0284] The target frequency band instructed to be switched by the network device 102 supports M-port transmission.

[0285] In some implementations, the fourth parameter includes RRC (Radio Resource Control, radio resource control protocol signaling), and the value of the RRC signaling is the first preset value or the second preset value. By way of example, the first preset value may be one T, and the second preset value may be two T.

[0286] In some implementations, the frequency band combination is used to perform uplink carrier aggregation in a terminal, and the frequency band combination includes at least two frequency bands.

[0287] For example, the terminal 101 supports uplink carrier aggregation in a frequency band combination, where the frequency band combination includes at least two frequency bands supported by the terminal 101 .

[0288] In the above technical solution, the first capability information is sent, and the first capability information is used to indicate that the terminal supports switching between M uplink antennas and / or switching between M uplink antennas to M antennas, and the switching is uplink transmission switching on multiple frequency bands, and the multiple frequency bands are frequency band combinations supported by the terminal, and M is an integer greater than or equal to 3. Therefore, the terminal reports the ability to support frequency band switching between multiple uplink antennas to avoid the problem of ambiguity in the switching mode of antenna switching.

[0289] Step S2102 , the network device 102 receives the first capability information sent by the terminal 101 .

[0290] In some embodiments, the first capability information is used to indicate that the terminal can switch between M uplink antennas and / or the terminal can switch from M uplink antennas to M antennas, wherein the switching is uplink transmission switching on multiple frequency bands, the multiple frequency bands are frequency band combinations supported by the terminal, and M is an integer greater than or equal to 3.

[0291] In some implementations, the uplink antenna is a channel for the terminal 101 to send uplink transmission signals. The name of the uplink antenna is not limited, and it may be, for example, "radio frequency link", "transmission link", "uplink antenna link", "uplink transmission link", etc.

[0292] In some embodiments, the name of the first capability information is not limited, and it may be, for example, "first indication information", "first reporting information", "antenna quantity information", "antenna switching capability information", etc.

[0293] In some embodiments, "obtain", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from high levels, obtaining by self-processing, autonomous implementation, etc.

[0294] In some embodiments, the method further comprises:

[0295] A first parameter is sent to the terminal, where the first parameter is used to indicate that the terminal determines, based on the first parameter, that the terminal can simultaneously perform frequency band switching between M uplink antennas and M antennas, and the switching is on the inter-band uplink carrier aggregation link or the supplementary uplink.

[0296] For example, in this embodiment, the first parameter sent by the network device 102 indicates that the switching mode of the M uplink antennas of the terminal 101 is configured in the inter-band uplink carrier aggregation link or the supplementary uplink. The network device 102 indicates the first parameter information to the terminal 101 to indicate that the terminal 101 supports the switching mode of the M uplink antennas in the inter-band UL CA (uplink carrier aggregation link) or SUL (Supplementary Uplink). After the terminal 101 receives the first parameter, it determines that the terminal 101 can support frequency band switching in the M uplink antennas according to the first parameter.

[0297] In some implementations, the first capability information includes second capability information, where the second capability information is used to indicate that M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink can perform frequency band switching, and the sending of the first capability information and the receiving of the first capability information include:

[0298] receiving the second capability information;

[0299] It is determined, according to the second capability information, that the terminal is capable of simultaneously switching frequency bands in the M uplink antennas.

[0300] For example, the second capability information is used to indicate that the terminal 101 supports frequency band switching for M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink. The terminal 101 can determine whether frequency band switching for M uplink antennas in an inter-band uplink carrier aggregation link or a supplementary uplink is supported in the terminal based on the configuration information of the device. When it is determined that the terminal 101 has the capability, the second capability information is generated. Based on the second capability information, it is determined that frequency band switching for M uplink antennas is supported in the terminal.

[0301] In some implementations, the method further includes: sending a second parameter to the terminal, where the second parameter is used to instruct the terminal to determine the antenna link state according to the second parameter.

[0302] By way of example, in this embodiment, after the network device 102 receives the first capability information sent by the terminal 101, when it is determined according to the first capability information that under the current switching strategy, when the terminal 101 switches the antenna link state, an antenna switching ambiguity problem will occur, a second parameter can be configured for the terminal 101 based on the current network state and the first capability information of the terminal 101 to indicate the antenna link state of each antenna link in the terminal 101 in the current state. After receiving the second parameter, the terminal 101 determines the current antenna link state. The antenna link state is the band pointed to by each of the M antennas in the terminal 101, or the band pointed to by some of the M antennas.

[0303] In some implementations, the above “sending the second parameter to the terminal” includes:

[0304] Sending a second parameter to the terminal, where the second parameter is used by the terminal to determine the antenna link state according to the second parameter after determining that the first condition is met, where the first condition includes one or more of the following:

[0305] When the terminal performs uplink antenna switching based on the first parameter sent by the network device, there are multiple switching modes, wherein the first parameter is used to indicate the frequency band switching between M uplink antennas and M antennas;

[0306] After the terminal sends the second capability information, there are multiple switching modes when performing uplink antenna switching, wherein the second capability information is used to indicate that the terminal supports M uplink antennas and M antennas simultaneously performing frequency band switching;

[0307] The terminal is configured for dual uplink transmission, which is used to indicate that the terminal supports simultaneous transmission of two frequency bands;

[0308] The terminal is configured for both uplink transmission, and both uplink transmission is used to indicate that the terminal supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band;

[0309] The terminal is configured for triple uplink transmission, which is used to indicate that the terminal supports simultaneous transmission in three frequency bands;

[0310] The terminal is configured for full uplink transmission, and the full uplink transmission is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0311] For example, in this embodiment, after receiving the second parameter sent by the network device 102, the terminal 101 determines the current state of the terminal 101 to determine whether the terminal 101 meets the first condition. The first condition includes one or more of the following:

[0312] The network device 102 sends a first parameter to instruct the terminal 101 to switch the frequency band on the M uplink antennas. After the terminal 101 receives the first parameter, when the switching requirement is met and the antenna is switched, there are multiple switching modes on the M uplink antennas, which will cause the switching ambiguity problem in the terminal 101. Therefore, the antenna link state of each antenna in the current state of the terminal 101 can be determined by the first parameter indicated by the network device, thereby avoiding the switching ambiguity problem. Among them, the first parameter includes the band information pointed to by each antenna.

[0313] After the terminal 101 sends the first capability information to the network device 102, it can determine whether it has the second capability based on the factory configuration information of the terminal 101. The second capability is the ability of the terminal to support M uplink antennas to switch frequency bands in an inter-band uplink carrier aggregation link or a supplementary uplink. When the terminal 101 determines that it supports the second capability, it reports the second capability information to the network device 102. After reporting the second capability information, when the terminal 101 switches the uplink antenna, there are multiple switching modes based on the M uplink antennas in the terminal 101, resulting in a switching ambiguity problem in the terminal 101. Therefore, at this time, it is necessary to determine the antenna link status of each antenna on the current M uplink antennas of the terminal 101.

[0314] The terminal 101 is configured for dual uplink transmission. When the terminal 101 switches M uplink antennas, a switching ambiguity problem may occur in the terminal 101. Dual uplink transmission uses two independent uplinks at the same time to send data in the terminal 101 to the two links in parallel for transmission, thereby improving transmission bandwidth and capacity and reducing data transmission delay.

[0315] Terminal 101 is configured for all uplink transmission, wherein all uplink transmission is used to indicate that the terminal 101 supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band on M antennas. Based on this configuration, when the terminal 101 switches the uplink antenna, it is impossible to determine which switching method to use to meet the current switching requirements, which can easily lead to switching ambiguity problems in the terminal 101. Therefore, in this state, it is necessary to indicate the antenna link status in the terminal 101 to determine the antenna link status of the terminal 101.

[0316] Terminal 101 is configured for three uplink transmissions, wherein the three uplink transmissions are used to indicate that three frequency bands are supported for simultaneous transmission on M antennas in terminal 101. Based on this configuration, when terminal 101 switches uplink antennas, it is impossible to determine how to configure the switching bands in the M uplink antennas, resulting in a switching ambiguity problem in terminal 101. Therefore, when terminal 101 is configured for three uplink transmissions, it is necessary to indicate the antenna link status in terminal 101 and determine the antenna link status of terminal 101.

[0317] The terminal is configured for full uplink transmission, and the full uplink transmission is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0318] Terminal 101 is configured for full uplink transmission, where full uplink transmission is used to indicate that terminal 101 supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band. At this time, the antenna link of terminal 101 supports multiple transmission modes. When terminal 101 switches uplink antennas, the switching frequency bands of each antenna cause switching ambiguity in terminal 101. Therefore, it is necessary to indicate the antenna link status in terminal 101.

[0319] Optionally, in some embodiments, the second parameter includes one or more of the following:

[0320] The second parameter is a first preset value, and the first preset value is used to indicate that an uplink antenna in the terminal supports the target frequency band;

[0321] The second parameter is a second preset value, and the second preset value is used to indicate that two uplink antennas in the terminal support the target frequency band;

[0322] The second parameter is a third preset value, and the third preset value is used to indicate that three uplink antennas in the terminal support the target frequency band.

[0323] For example, in this embodiment, the second parameter includes a target frequency band to which the terminal 101 needs to switch, and the second parameter is a first pre-value, wherein the first pre-value may be one T, which is used to indicate that there is one uplink antenna in the terminal 101 that supports the target frequency band; the second parameter is a second pre-value, wherein the second pre-value may be two T, which is used to indicate that there are two uplink antennas in the terminal 101 that support the target frequency band; the second parameter is a third pre-value, wherein the third pre-value may be three T, which is used to indicate that there are three uplink antennas in the terminal 101 that support the target frequency band.

[0324] In some implementations, the method further includes: sending a third parameter to the terminal, where the third parameter is used to indicate that three uplink antennas in the terminal support multiple frequency bands.

[0325] For example, in this embodiment, the network device 102 sends a third parameter to indicate the antenna switching mode in the terminal 101, wherein the third parameter is used to indicate the multiple frequency bands supported by the three uplink antennas in the terminal. That is, after receiving the first capability information sent by the terminal 101, the network device 102 configures the third parameter indicating the switching mode for the terminal 101 based on the capability of the terminal 101, thereby indicating the multiple frequency bands supported by the three uplink antennas in the terminal 101.

[0326] In some implementations, the above “sending the third parameter to the terminal” includes:

[0327] Sending a third parameter to the terminal, where the third parameter is used by the terminal to determine that three uplink antennas in the terminal support multiple frequency bands according to the third parameter after determining that the second condition is met, where the second condition includes one or more of the following:

[0328] When the terminal performs uplink antenna switching based on the first parameter sent by the network device, there are multiple switching modes, wherein the first parameter is used to indicate the frequency band switching between M uplink antennas and M antennas;

[0329] After the terminal sends the second capability information, there are multiple switching modes when performing uplink antenna switching, wherein the second capability information is used to indicate that the terminal supports M uplink antennas and M antennas simultaneously performing frequency band switching;

[0330] The terminal is configured for duplex transmission, which is used to indicate that the terminal supports simultaneous transmission in two frequency bands;

[0331] The terminal is configured for full-duplex transmission, which indicates that the terminal supports simultaneous transmission of two frequency bands and separate transmission of a single frequency band;

[0332] The terminal is configured for triplex transmission, which is used to indicate that the terminal supports simultaneous transmission in three frequency bands;

[0333] The terminal is configured for full triplex transmission, which is used to indicate that the terminal supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band.

[0334] For example, after receiving the third parameter fed back by the network device 102, the terminal 101 determines the current switching state of the terminal 101 to determine whether the terminal 101 meets the second condition, wherein the second condition includes one or more of the following:

[0335] When the terminal 101 receives the first parameter sent by the network device to switch the uplink antenna, if there are multiple switching methods based on the M uplink antennas in the terminal 101, the third parameter is used to indicate the multiple frequency bands supported by the three uplink antennas in the terminal, wherein the first parameter is used to indicate the switching mode between M uplink antennas and M antennas.

[0336] When the terminal 101 determines that it supports M uplink antennas for frequency band switching in an inter-band uplink carrier aggregation link or a supplementary uplink, the terminal 101 sends the second capability information to the network device 102. When the uplink antenna switching is performed after sending the second capability information, there are multiple switching modes in the terminal 101. The second parameter sent by the network device 102 is required to determine the antenna link status in the terminal 101.

[0337] Terminal 101 is configured for duplex transmission, wherein duplex transmission is used to indicate that terminal 101 supports simultaneous transmission in two frequency bands when performing antenna switching. At this time, if antenna switching is indicated in terminal 101, based on the configuration of duplex transmission, an antenna switching ambiguity problem will occur in terminal 101. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0338] Terminal 101 is configured for full-duplex transmission, wherein full-duplex transmission is used to indicate that the terminal supports simultaneous transmission in two frequency bands and separate transmission in a single frequency band. Based on the full-duplex transmission configuration in terminal 101, when performing antenna switching, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas in the current antennas are selected for frequency band switching, and the target frequency band to which the corresponding switched antennas need to be switched. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0339] Terminal 101 is configured for triplex transmission, wherein triplex transmission is used to indicate that terminal 101 supports simultaneous transmission in three frequency bands. Based on the triplex transmission configuration in terminal 101, when performing antenna switching, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas to select for frequency band switching. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0340] Terminal 101 is configured for full triplex transmission, wherein full triplex transmission is used to indicate that terminal 101 supports simultaneous transmission of three frequency bands, simultaneous transmission of two frequency bands, and separate transmission of a single frequency band. Based on the full triplex transmission configuration in terminal 101, when antenna switching is performed, an antenna switching ambiguity problem will occur in terminal 101, making it impossible for terminal 101 to determine which antennas are selected for frequency band switching. Therefore, it is necessary to indicate the antenna link status in terminal 101 based on the second parameter.

[0341] In some embodiments, the method further includes: sending a fourth parameter to the terminal, the fourth parameter being used to instruct the terminal to point all frequency bands supported by M uplink antennas to a target frequency band according to the fourth parameter, the target frequency band being a scheduled frequency band to be transmitted.

[0342] For example, in this embodiment, the network device 102 indicates the antenna switching mode in the terminal 101 based on the first capability information sent by the terminal 101, generates a fourth parameter and sends it to the terminal 101, wherein the fourth parameter is used to instruct the terminal 101 to point all the frequency bands supported by the M uplink antennas to the target frequency band, which is the scheduled frequency band to be transmitted. The terminal 101 points all the frequency bands supported by the M uplink antennas to the target frequency band according to the fourth parameter.

[0343] In some implementations, the “sending the fourth parameter to the terminal” includes:

[0344] Sending a fourth parameter to the terminal, where the fourth parameter is used by the terminal to point all frequency bands supported by M uplink antennas of the terminal to the target frequency band according to the fourth parameter after determining that the third condition is met; wherein the third condition includes one or more of the following:

[0345] The target frequency band is not configured with a related frequency band;

[0346] The target frequency band is not configured with a related frequency band group;

[0347] The target frequency band is scheduled for M-port transmission;

[0348] The target frequency band supports M-port transmission.

[0349] For example, in this embodiment, after receiving the fourth parameter, the terminal 101 determines the current state of the terminal 101 to determine whether the terminal 101 satisfies the third condition. When it is determined that the terminal 101 satisfies the third condition, according to the fourth parameter, the frequency bands supported by the M uplink antennas of the terminal 101 are all directed to the target frequency band, wherein the third condition includes one or more of the following:

[0350] A related frequency band that is not configured with a target frequency band among the target frequency bands indicated by the network device 102;

[0351] The target frequency band instructed to be switched by the network device 102 does not have a frequency band group associated with the target frequency band configured;

[0352] The target frequency band indicated by the network device 102 needs to be transmitted simultaneously through the M-port process;

[0353] The target frequency band instructed to be switched by the network device 102 supports M-port transmission.

[0354] In some implementations, the fourth parameter includes RRC (Radio Resource Control, radio resource control protocol signaling), and the value of the RRC signaling is the first preset value or the second preset value. By way of example, the first preset value may be one T, and the second preset value may be two T.

[0355] In some implementations, the frequency band combination is used to perform uplink carrier aggregation in a terminal, and the frequency band combination includes at least two frequency bands.

[0356] For example, the terminal 101 supports uplink carrier aggregation in a frequency band combination, where the frequency band combination includes at least two frequency bands supported by the terminal 101 .

[0357] In the above technical solution, the network device determines the antenna switching capability of the terminal according to the first capability information sent by the terminal, and configures the corresponding antenna switching indication for the terminal according to the antenna switching capability. Thus, the terminal reports the ability to support frequency band switching between multiple uplink antennas, so as to avoid the problem of ambiguity in the switching mode of antenna switching.

[0358] FIG3 is a flow chart of a communication method according to an embodiment of the present disclosure. The method is executed by the terminal 101. As shown in FIG3 , the method includes the following steps:

[0359] Step S3101, sending first capability information.

[0360] In some implementations, the network device 102 receives first capability information.

[0361] In some embodiments, the first capability information is used to indicate that the terminal supports switching between M uplink antennas and / or switching between M uplink antennas to M antennas, where the switching is uplink transmission switching on multiple frequency bands, the multiple frequency bands are frequency band combinations supported by the terminal, and M is an integer greater than or equal to 3.

[0362] The relevant implementation method of step S3101 in the embodiments of the present disclosure can refer to the embodiment of the aforementioned step S2101, which will not be repeated here.

[0363] Through the above technical solution, the first capability information is sent, and the first capability information is used to indicate that the terminal supports switching between M uplink antennas and / or switching between M uplink antennas to M antennas, and the switching is uplink transmission switching on multiple frequency bands, and the multiple frequency bands are frequency band combinations supported by the terminal, and M is an integer greater than or equal to 3. Therefore, the terminal reports the ability to support frequency band switching between multiple uplink antennas to avoid the problem of ambiguity in the switching mode of antenna switching.
