Description

Technical Field

[0001] This application relates to the field of network communication technologies, and in particular, to a configuration method, apparatus, related device, and storage medium. Background Art

[0002] Multiple-Input, Multiple-Output (MIMO) means that multiple antennas are used at both the transmitting end and the receiving end. According to the terminal antenna configuration requirements, a New Radio (NR) terminal must support 4 receiving antennas in the n41 frequency band (e.g., 2.6 GHz), and at least 2 receiving antennas need to be configured in the n40 frequency band. Simultaneous transmission and reception means that uplink and downlink transmissions are carried out simultaneously on different subcarriers after Carrier Aggregation (CA).

[0003] In the current terminal, the n40 and n41 frequency bands share 4 antennas. The carrier aggregation CA_n40-n41 of the two frequency bands supports 2-transmit 4-receive MIMO transmission, but does not support the ability of simultaneous transmission and reception. Summary of the Invention

[0062] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0063] MIMO (Multiple-Input Multiple-Output) means that multiple antennas are used at both the transmitting end and the receiving end. According to the terminal antenna configuration requirements in related technologies, NR terminals must support 4 receiving antennas in the n41 frequency band (2.6 GHz), and at least 2 receiving antennas need to be configured in the n40 frequency band. Simultaneous transmission and reception means that uplink and downlink transmissions are carried out simultaneously on different subcarriers after CA (Carrier Aggregation).

[0064] In the current terminal, the n40 and n41 frequency bands share 4 antennas. The carrier aggregation CA_n40 - n41 of the two frequency bands supports 2-transmit 4-receive MIMO transmission, but does not support the ability of simultaneous transmission and reception.

[0065] The n40 and n41 are relatively close to each other. Currently, the terminal design adopts the method of sharing 4 antennas for the two frequency bands. In the case of non-simultaneous transmission and reception, since the uplink and downlink transmissions are not carried out simultaneously, when the subcarrier n40 performs 2-antenna uplink transmission, the subcarrier n41 will not perform 4-antenna downlink reception. Therefore, even if the two frequency bands share 4 antennas, CA_n40 - n41 can still communicate normally.

[0066] The ability of simultaneous transmission and reception means that when performing carrier aggregation, different subcarriers can simultaneously carry out uplink and downlink transmissions on different antennas. Terminals that support this method can make more full use of the current frequency resources. Combining the two capabilities of MIMO and simultaneous transmission and reception will bring an improvement in the overall transmission rate of the uplink and downlink.

[0067] For the current terminal, if it supports both MIMO and the ability of simultaneous transmission and reception, there will be the following problems under the current rules:

[0068] 1. The reporting of the terminal's support for uplink MIMO capability and the reporting of the support for the ability of simultaneous transmission and reception are independent, and it is impossible to determine whether the MIMO antenna configuration at this time combines the ability of simultaneous transmission and reception. At this time, there is a situation where the terminal supports the two capabilities separately, but cannot report whether it can support the two capabilities simultaneously. Therefore, there is a possibility of not being able to select the optimal antenna configuration under the current conditions;

[0069] 2. If the terminal supports both MIMO and the ability of simultaneous transmission and reception, for CA_n40 - n41, since the frequencies of the two subcarriers are relatively close, the terminal needs to add additional filters or antennas. In the case of supporting the ability of simultaneous transmission and reception and the antenna configuration being 2-transmit 4-receive, the terminal needs at least 6 independent antennas. The method of adding new antennas may be feasible for some terminals, but it is difficult to implement for devices with a small volume such as handheld terminals.

[0070] Based on this, the embodiment of the present application provides a configuration method, which is applied to a network device. Figure 1Schematic flowchart of the configuration method for embodiments of this application; as Figure 1 shown, the method includes:

[0071] Step 101: Receive a first signaling reported by a terminal; the first signaling indicates whether the terminal has the functions of simultaneously supporting MIMO and supporting simultaneous uplink and downlink transmission.

[0072] Step 102: When the first signaling indicates that the terminal has the functions of simultaneously supporting MIMO and supporting simultaneous uplink and downlink transmission, configure the antennas of the terminal based on the MIMO and the functions of uplink and downlink transmission.

[0073] It should be noted that the network device can be any network device, which is not limited herein. As an example, the network device can at least include a base station. The terminal can also be determined according to the actual situation, which is not limited herein. As an example, the terminal can include a smart phone, a tablet computer, a desktop computer, a notebook, a client, etc.

[0074] In step 101, the first signaling can be determined according to the actual situation, which is not limited herein. As an example, the first signaling can be signaling. The first signaling can be reported in the parameters related to NR carrier aggregation. For example, the parameters related to NR carrier aggregation will be reported in specific parameters (for example, CA-ParametersNR); the fact that the first signaling indicates whether the terminal has the functions of simultaneously supporting MIMO and supporting simultaneous uplink and downlink transmission can be understood as the first signaling indicating that the terminal simultaneously has the functions of supporting MIMO and uplink and downlink transmission; or, the first signaling indicates that the terminal has the function of supporting MIMO or uplink and downlink transmission; or, the first signaling indicates that the terminal does not simultaneously have the functions of supporting MIMO and uplink and downlink transmission.

[0075] The first signaling reported by the receiving terminal can be understood as the signaling that the network device receives from the terminal; as an example, this signaling can be reported in the parameters related to NR carrier aggregation. For example, the parameters related to NR carrier aggregation will be reported in specific parameters (e.g., CA-ParametersNR); when the terminal reports simultaneousRxTxInterBandCAPerBandPair, it means that the terminal supports simultaneous transmission and reception of inter-band NR carrier aggregation for TDD-TDD and TDD-FDD at this time. If the terminal can support simultaneous transmission and reception of NR carrier aggregation and a new reporting parameter simultaneousRxTxInterBandCAPerBandPairWithMIMO is added in the parameter CA-ParametersNR. If the parameter reported in CA-ParametersNR contains simultaneousRxTxInterBandCAPerBandPairWithMIMO, it means that the terminal can support both the capabilities of simultaneous uplink and downlink transmission and MIMO. simultaneousRxTxInterBandCAPerBandPair indicates whether the reported terminal supports simultaneous transmission and reception; simultaneousRxTxInterBandCAPerBandPairWithMIMO indicates whether the reported terminal supports both simultaneous transmission and reception and MIMO.

[0076] In practical applications, by the network device receiving the first signaling reported by the terminal, which characterizes whether the terminal has the functions of supporting multiple-input multiple-output (MIMO) and uplink and downlink transmission, it is convenient for the network device to select the optimal antenna for configuration under the current conditions to improve the uplink and downlink transmission rates.

[0077] In step 102, when the first signaling characterizes that the terminal has the functions of simultaneously supporting MIMO and supporting simultaneous uplink and downlink transmission, the function of uplink and downlink transmission can be understood as that the terminal has two capabilities of simultaneously supporting MIMO and the uplink and downlink transmission functions.

[0078] Configuring the antennas of the terminal based on the functions of the MIMO and the uplink and downlink transmissions can be understood as configuring the antennas of the terminal in a manner that combines the functions of the MIMO and the uplink and downlink transmissions. The manner of configuring the antennas of the terminal by combining the functions of the MIMO and the uplink and downlink transmissions can be defined according to the actual situation and is not defined herein. As an example, the manner of configuring the antennas of the terminal by combining the functions of the MIMO and the uplink and downlink transmissions can be to configure the antennas of the terminal based on the functions of the MIMO and the uplink and downlink transmissions with parameters indicating that the network device allows the terminal to support the functions of the MIMO and the uplink and downlink transmissions; these parameters can be defined according to the actual situation and are not defined herein. As an example, these parameters can be signaling parameters; the signaling parameters can include descriptions of network-side signaling. For example, simultaneousRxTxInterBandCAPerBandPair represents the terminal's support for simultaneous reception and transmission configured by the network side; imultaneousRxTxInterBandCAPerBandPairWithMIMO represents whether the terminal can support MIMO and simultaneous uplink and downlink transmissions simultaneously, enable represents that the network side allows the terminal to configure for simultaneous support of MIMO and simultaneous uplink and downlink transmissions, and disabled indicates that this capability is not supported, that is, it represents that the network side does not allow the terminal to configure for simultaneous support of MIMO and simultaneous uplink and downlink transmissions.

[0079] In an embodiment of the present application, by introducing a signaling for the terminal to report whether it has the function of supporting MIMO and uplink and downlink transmissions, when the signaling indicates that the terminal has the function of supporting the MIMO and the uplink and downlink transmissions, the antennas of the terminal are configured based on the functions of the MIMO and the uplink and downlink transmissions; it is achieved that the reporting of the terminal's MIMO capability and the reporting of the capability of supporting simultaneous reception and transmission are not independent, and the antennas are configured in a manner that combines the two capabilities of MIMO and simultaneous reception and transmission, greatly improving the transmission rate of the uplink and downlink.

[0080] In one embodiment, the method further includes:

[0081] When the first signaling indicates that the terminal does not have the function of supporting MIMO and the function of supporting simultaneous uplink and downlink transmissions, receive the priority information corresponding to the function of the MIMO or the function of the uplink and downlink transmissions sent by the terminal.

[0082] Configure the antenna of the terminal by using the function of the MIMO or the function of the uplink and downlink transmission based on the priority information.

[0083] In this embodiment, when the first signaling indicates that the terminal does not have the function of simultaneously supporting the MIMO and the function of supporting the uplink and downlink transmission at the same time, it can be understood that the current terminal can report whether it supports MIMO or simultaneous uplink and downlink transmission, but it cannot report whether it can support both capabilities at the same time.

[0084] Receive the priority information corresponding to the function of the MIMO or the function of the uplink and downlink transmission sent by the terminal; wherein, the priority information can be determined according to the actual situation and is not limited herein. As an example, the priority information may include configuring the antenna in a manner that preferentially uses the function of the MIMO or configuring the antenna in a manner that preferentially uses the function of the uplink and downlink transmission. In practical applications, the priority information can be determined by the terminal manufacturer; for example, the terminal manufacturer determines the priority information corresponding to the function of the MIMO or the function of the uplink and downlink transmission sent by the terminal through a statement, which can also be understood as the terminal manufacturer determining the priority of the two capabilities through a statement.

[0085] Configuring the antenna of the terminal by using the function of the MIMO or the function of the uplink and downlink transmission based on the priority information can be understood as follows: if the priority information is to configure the antenna in a manner that preferentially uses the function of the MIMO, then configure the antenna in the manner of using the function of the MIMO; if the priority information is to configure the antenna in a manner that preferentially uses the function of the uplink and downlink transmission, then configure the antenna in the manner of using the function of the uplink and downlink transmission.

[0086] In practical applications, if the signaling reports that the terminal cannot support simultaneous transceiver and MIMO at the same time, the priority of the above two capabilities is determined by the statement, and one of the methods is used to configure the antenna.

[0087] In one embodiment, the configuring the antenna of the terminal based on the MIMO and the function of the uplink and downlink transmission includes:

[0088] Configure the first parameter of the antenna of the terminal based on the MIMO and the function of the uplink and downlink transmission; the first parameter indicates that the network device allows the terminal to be configured to support the MIMO and the function of supporting the uplink and downlink transmission at the same time.

[0089] In this embodiment, the first parameter can be defined according to the actual situation and will not be limited here. As an example, the first parameter may include signaling parameters, network parameters, etc.; the signaling parameters may include descriptions of network-side signaling. For example, simultaneousRxTxInterBandCAPerBandPair represents that the terminal configured by the network side supports simultaneous transmission and reception; simultaneousRxTxInterBandCAPerBandPairWithMIMO represents whether the terminal can support MIMO and simultaneous uplink and downlink transmission at the same time. enable represents that the network side allows the terminal to perform the configuration of supporting MIMO and simultaneous uplink and downlink transmission at the same time, and disabled means that this capability is not supported, that is, it represents that the network side does not allow the terminal to perform the configuration of supporting MIMO and simultaneous uplink and downlink transmission at the same time.

[0090] Understanding the first parameter of the antenna configuration of the terminal based on the functions of the MIMO and the uplink and downlink transmission can be understood as that after the network-side device confirms that the terminal has the ability to support simultaneous uplink and downlink transmission and MIMO ability, it performs parameter configuration to determine whether to configure the terminal to perform simultaneous transmission and reception and MIMO configuration.

[0091] In practical applications, after the network side confirms that the terminal has the ability to support simultaneous uplink and downlink transmission and MIMO ability, it performs network configuration on the base station side to determine whether to configure the terminal to perform simultaneous transmission and reception and MIMO configuration. The description of the network-side signaling, simultaneousRxTxInterBandCAPerBandPair represents that the terminal configured by the network side supports simultaneous transmission and reception;

[0092] simultaneousRxTxInterBandCAPerBandPairWithMIMO represents whether the terminal can support MIMO and simultaneous uplink and downlink transmission at the same time. enable represents that the network side allows the terminal to perform the configuration of supporting MIMO and simultaneous uplink and downlink transmission at the same time, and disabled means that this capability is not supported.

[0093] In this embodiment, after learning about the terminal's ability, the network side can perform antenna scheduling for the terminal according to the actual situation to confirm whether the terminal can be configured in a way that supports MIMO and simultaneous uplink and downlink transmission at the same time.

[0094] In this embodiment, the terminal first reports its capabilities through simultaneousRxTxInterBandCAPerBandPair, indicating whether it supports MIMO and simultaneous uplink and downlink transmission capabilities. After learning about the terminal's capabilities, the network side can perform antenna scheduling for the terminal according to the actual situation to confirm whether the terminal can be configured to use the MIMO and simultaneous uplink and downlink transmission methods simultaneously.

[0095] In one embodiment, the method further includes:

[0096] When the terminal is a handheld terminal, determining whether the handheld terminal performs carrier aggregation in a first frequency band and a second frequency band;

[0097] When the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, obtaining a first number of receiving antennas supported by the handheld terminal in the first frequency band;

[0098] Configuring a second signaling based on the first signaling; the second signaling includes releasing the limitation on the first number of receiving antennas supported by the first frequency band and adjusting the first number to a second number; the second number is less than the first number;

[0099] Sending the second signaling to the handheld terminal; the second signaling is used for the handheld terminal to adjust the first number of receiving antennas supported by the handheld terminal in the first frequency band to the second number when the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band.

[0100] In this embodiment, the handheld terminal can be determined according to the actual situation and is not limited herein. As an example, the handheld terminal can be a terminal with a small volume.

[0101] Both the first frequency band and the second frequency band can be determined according to the actual situation and are not limited herein. As an example, the first frequency band can be the n41 frequency band; the second frequency band can be the n40 frequency band.

[0102] Determining whether the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band can be understood as determining whether the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, and obtaining a judgment result that the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, or the handheld terminal does not perform carrier aggregation in the first frequency band and the second frequency band. As an example, determining whether the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, and obtaining a judgment result that the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, or the handheld terminal does not perform carrier aggregation in the first frequency band and the second frequency band can be to determine whether the handheld terminal performs carrier aggregation in the n41 and n40 frequency bands, and obtain a judgment result that the handheld terminal performs carrier aggregation in the n41 frequency band and the n40 frequency band, or the handheld terminal does not perform carrier aggregation in the n41 and n40 frequency bands.

[0103] When the handheld terminal performs carrier aggregation in the first frequency band and the second frequency band, obtain the first number of receiving antennas supported by the handheld terminal in the first frequency band; wherein, the first number can be determined according to the actual situation and is not limited herein. As an example, the first number can be 4.

[0104] The second signaling includes releasing the restriction on the first number of receiving antennas supported by the first frequency band and adjusting the first number to the second number; wherein, releasing the restriction on the first number of receiving antennas supported by the first frequency band can be understood as relaxing the restriction on the first number of receiving antennas supported by the first frequency band. The second number is less than the first number; wherein, both the first number and the second number can be determined according to the actual situation and are not limited herein. As an example, the first number can be 4 and the second number can be 2.

[0105] Configure the second signaling based on the first signaling; wherein, the second signaling can be determined according to the actual situation and is not limited herein. As an example, the second signaling can be a signaling configured by the network.

[0106] In one embodiment, the second signaling includes a second parameter, and the second parameter characterizes a configuration of whether the network device allows the terminal to simultaneously support the MIMO and the function of supporting simultaneous uplink and downlink transmissions; the method further includes:

[0107] When the second parameter characterizes that the network device does not allow the terminal to simultaneously support the MIMO and the function of supporting simultaneous uplink and downlink transmissions, the second signaling is used to indicate not to configure the antennas of the handheld terminal;

[0108] In the case where the second parameter characterizes the configuration in which the network device allows the terminal to support both MIMO and the function of supporting simultaneous uplink and downlink transmission, the second signaling is used to instruct the antenna of the handheld terminal to be reconfigured to support the function of simultaneous uplink and downlink transmission.

[0109] In this embodiment, the second signaling includes a second parameter, where the second parameter can be determined according to the actual situation and is not limited herein. As an example, the second parameter can be a configuration parameter. In practical applications, the configuration parameter can be enable or disable; where disable characterizes the configuration in which the network device does not allow the terminal to support the functions of MIMO and uplink and downlink transmission; enable characterizes the configuration in which the network device allows the terminal to support the functions of MIMO and uplink and downlink transmission.

[0110] In the case where the second parameter characterizes the configuration in which the network device does not allow the terminal to support both MIMO and the function of supporting simultaneous uplink and downlink transmission, the second signaling is used to indicate that the antenna of the handheld terminal is not configured. It can be understood that in the case where the second parameter characterizes the configuration in which the network device does not allow the terminal to support both MIMO and the function of supporting simultaneous uplink and downlink transmission, the second signaling indicates that it does not affect the normal antenna configuration. As an example, when the second parameter in the second signaling is disable, it does not affect the normal antenna configuration.

[0111] In the case where the second parameter characterizes the configuration in which the network device allows the terminal to support both MIMO and the function of supporting simultaneous uplink and downlink transmission, the second signaling is used to instruct the antenna of the handheld terminal to be reconfigured to support the function of simultaneous uplink and downlink transmission; where the second signaling can be a network-configured signaling. As an example, when the network-configured signaling simultaneousRxTxInterBandCAPerBandPairWithMIMO is enable, when n40 and n41 perform carrier aggregation, the antenna configuration can be switched from 2t4r to 2t2r. Switching from 2t4r to 2t2r can be understood as switching from 2-antenna uplink configuration and 4-antenna downlink configuration to 2-antenna uplink configuration and 2-antenna downlink configuration.

[0112] In practical applications, when the signaling feedback of the network simultaneousRxTxInterBandCAPerBandPairWithMIMO is enabled, an additional statement is made regarding the downlink antenna configuration and downlink SRS transmission during carrier aggregation of frequency bands n40 and n41 to meet the antenna requirements for the terminal and the network during simultaneous MIMO and simultaneous uplink and downlink transmission, that is, it is additionally stated that the number of receiving antennas at this time can be set to "2" or the transceiver antenna requirement at this time is "2t2r".

[0113] Correspondingly, an embodiment of the present application further provides a data transmission method, which is applied to a terminal. Figure 2 This is another schematic flowchart of the configuration method of the embodiment of the present application; as Figure 2 shown, the method includes:

[0114] Step 201: Report a first signaling to a network device; the first signaling indicates whether the terminal has the function of simultaneously supporting MIMO and supporting simultaneous uplink and downlink transmission; the first signaling is used for the network device to configure the antennas of the terminal based on the MIMO and the uplink and downlink transmission functions when the first signaling indicates that the terminal has the function of simultaneously supporting the MIMO and supporting the simultaneous uplink and downlink transmission function.

[0115] It should be noted that the network device can be any network device and is not limited herein. As an example, the network device may at least include a base station. The terminal can also be determined according to the actual situation and is not limited herein. As an example, the terminal may include a smart phone, a tablet computer, a desktop computer, a notebook, a client, etc.

[0116] In step 201, the first signaling can be determined according to the actual situation and is not limited herein. As an example, the first signaling can be a signaling. The first signaling can be reported in the parameters related to NR carrier aggregation. For example, the parameters related to NR carrier aggregation will be reported in specific parameters (such as, CA-ParametersNR); the first signaling indicating whether the terminal has the function of simultaneously supporting multiple input multiple output MIMO and supporting simultaneous uplink and downlink transmission can be understood as the first signaling indicating that the terminal simultaneously has the function of supporting MIMO and uplink and downlink transmission; or, the first signaling indicates that the terminal has the function of supporting MIMO or uplink and downlink transmission; or, the first signaling indicates that the terminal does not simultaneously have the function of supporting MIMO and uplink and downlink transmission.

[0117] Reporting the first signaling to the network device can be understood as the terminal reporting signaling to the network device; as an example, this signaling can be reported through the parameters related to NR carrier aggregation. For example, the parameters related to NR carrier aggregation will be reported in specific parameters (e.g., CA-ParametersNR); when the terminal reports simultaneousRxTxInterBandCAPerBandPair, it means that the terminal supports simultaneous transmission and reception of TDD-TDD and TDD-FDD inter-band NR carrier aggregation at this time. If the terminal can support simultaneous transmission and reception of NR carrier aggregation and add the reporting parameter simultaneousRxTxInterBandCAPerBandPairWithMIMO in the parameter CA-ParametersNR. If the parameter reported in CA-ParametersNR contains simultaneousRxTxInterBandCAPerBandPairWithMIMO, it means that the terminal can support both simultaneous uplink and downlink transmission and MIMO capabilities. simultaneousRxTxInterBandCAPerBandPair indicates whether the terminal supports simultaneous transmission and reception; simultaneousRxTxInterBandCAPerBandPairWithMIMO indicates whether the terminal supports both simultaneous transmission and reception and MIMO at the same time.

[0118] The first signaling is used for the network device to configure the antennas of the terminal based on the MIMO and the uplink and downlink transmission functions when the first signaling indicates that the terminal has the functions of simultaneously supporting MIMO and supporting uplink and downlink transmission. Among them, configuring the antennas of the terminal based on the MIMO and the uplink and downlink transmission functions can be understood as configuring the antennas of the terminal in a way that combines the functions of MIMO and the uplink and downlink transmission. The way of configuring the antennas of the terminal by combining the functions of MIMO and the uplink and downlink transmission can be defined according to the actual situation and is not defined here. As an example, the way of configuring the antennas of the terminal by combining the functions of MIMO and the uplink and downlink transmission can be to configure the parameters representing that the network device allows the terminal to support the functions of MIMO and the uplink and downlink transmission based on the MIMO and the uplink and downlink transmission functions; these parameters can be defined according to the actual situation and are not defined here. As an example, these parameters can be signaling parameters; the signaling parameters can include descriptions of network-side signaling. For example, simultaneousRxTxInterBandCAPerBandPair represents the terminal's support for simultaneous transceiver transmission configured by the network side; imultaneousRxTxInterBandCAPerBandPairWithMIMO represents whether the terminal can simultaneously support MIMO and simultaneous uplink and downlink transmission, enable represents that the network side allows the terminal to perform configuration for simultaneously supporting MIMO and simultaneous uplink and downlink transmission, and disabled means not supporting this capability, that is, it represents that the network side does not allow the terminal to perform configuration for simultaneously supporting MIMO and simultaneous uplink and downlink transmission.

[0119] In this embodiment, new signaling reports to the network indicating whether the terminal has the ability to simultaneously support MIMO and simultaneous uplink and downlink transmission. As an example, the terminal first reports its capabilities through simultaneousRxTxInterBandCAPerBandPair, indicating whether it supports the capabilities of simultaneous MIMO and simultaneous uplink and downlink transmission. After learning about the terminal's capabilities, the network side can perform antenna scheduling for the terminal according to the actual situation to confirm whether the terminal can be configured in a way of simultaneously performing MIMO and simultaneous uplink and downlink transmission.

[0120] In an embodiment of the present application, by introducing a signaling for the terminal to report whether the terminal has the function of supporting MIMO and uplink and downlink transmission, when the signaling indicates that the terminal has the function of supporting the MIMO and the uplink and downlink transmission, the antenna of the terminal is configured based on the MIMO and the function of the uplink and downlink transmission; it is realized that the reporting of the terminal's MIMO capability and the reporting of the capability of supporting simultaneous transceiver are not independent, and the antenna is configured by combining the two capabilities of MIMO and simultaneous transceiver, which greatly improves the transmission rate of the uplink and downlink.

[0121] In one embodiment, the method further includes:

[0122] When the first signaling indicates that the terminal does not have the function of simultaneously supporting the MIMO function and the function of supporting simultaneous uplink and downlink transmission, the priority information corresponding to the MIMO function or the uplink and downlink transmission function is sent to the network device; the priority information is used for the network device to configure the antenna of the terminal by using the MIMO function or the uplink and downlink transmission function.

[0123] In this embodiment, when the first signaling indicates that the terminal does not have the function of simultaneously supporting the MIMO function and the function of supporting simultaneous uplink and downlink transmission, it can be understood that the current terminal can report whether it supports MIMO or simultaneous uplink and downlink transmission, but it cannot report whether it can support both capabilities simultaneously.

[0124] Sending the priority information corresponding to the MIMO function or the uplink and downlink transmission function to the network device can be understood as the terminal sending the priority information corresponding to the MIMO function or the uplink and downlink transmission function to the network device; wherein, the priority information can be determined according to the actual situation and is not limited herein. As an example, the priority information can include preferentially configuring the antenna by using the MIMO function or preferentially configuring the antenna by using the uplink and downlink transmission function. In practical applications, the priority information can be determined by the terminal manufacturer; for example, by the terminal manufacturer determining the priority information corresponding to the MIMO function or the uplink and downlink transmission function sent by the terminal through a statement, or it can also be understood as determining the priority of the two capabilities through a statement by the terminal manufacturer.

[0125] The priority information is used for the network device to configure the antennas of the terminal by using the function of the MIMO or the function of the uplink and downlink transmission. It can be understood that if the priority information is to preferentially use the function of the MIMO for antenna configuration, then the function of the MIMO is used for antenna configuration; if the priority information is to preferentially use the function of the uplink and downlink transmission for antenna configuration, then the function of the uplink and downlink transmission is used for antenna configuration.

[0126] In practical applications, if the signaling reporting terminal cannot support simultaneous transceiver and MIMO at the same time, the priority of the above two capabilities is determined by the declaration, and one of the methods is used for antenna configuration.

[0127] In one embodiment, the method further includes:

[0128] Determine whether the terminal has the function of uplink and downlink transmission;

[0129] When the terminal has the function of uplink and downlink transmission, report the first signaling to the network device.

[0130] In this embodiment, determining whether the terminal has the function of uplink and downlink transmission can be understood as determining whether the terminal has the function of uplink and downlink transmission, and obtaining a judgment result that the terminal has the function of uplink and downlink transmission or the terminal does not have the function of uplink and downlink transmission.

[0131] When the terminal has the function of uplink and downlink transmission, reporting the first signaling to the network device can be understood as reporting the first signaling when the terminal supports simultaneous uplink and downlink transmission.

[0132] In this embodiment, in order to reduce signaling overhead, this signaling is only reported when the terminal supports simultaneous uplink and downlink transmission.

[0133] In one embodiment, the method further includes:

[0134] When the terminal does not have the function of uplink and downlink transmission, if the terminal has a function requirement for MIMO, configure the antennas of the terminal according to the function requirement.

[0135] In this embodiment, mainly when the terminal does not support simultaneous transceiver, this signaling is not reported, and when there is a MIMO requirement, it is configured according to the normal MIMO antenna requirements.

[0136] In one embodiment, the method further includes:

[0137] When the terminal is a handheld terminal, receive a second signaling sent by the network device;

[0138] When the handheld terminal performs carrier aggregation in a first frequency band and a second frequency band, based on the second signaling, adjust the first number of receiving antennas supported by the handheld terminal in the first frequency band to the second number.

[0139] In this embodiment, the handheld terminal can be determined according to the actual situation and is not limited herein. As an example, the handheld terminal can be a terminal with a relatively small volume.

[0140] Both the first frequency band and the second frequency band can be determined according to the actual situation and are not limited herein. As an example, the first frequency band can be the n41 frequency band; the second frequency band can be the n40 frequency band.

[0141] Based on the second signaling, adjust the first number of receiving antennas supported by the handheld terminal in the first frequency band to the second number. Wherein, both the first number and the second number can be determined according to the actual situation and are not limited herein. As an example, the first number can be 4 and the second number can be 2.

[0142] In one embodiment, the second signaling includes a second parameter, and the second parameter characterizes a configuration of whether the network device allows the terminal to support both the MIMO and the function of supporting simultaneous uplink and downlink transmission; the method further includes:

[0143] When the second parameter characterizes that the network device does not allow the terminal to support both the MIMO and the function of supporting simultaneous uplink and downlink transmission, do not configure the antennas of the handheld terminal based on the second signaling;

[0144] When the second parameter characterizes that the network device allows the terminal to support both the MIMO and the function of supporting simultaneous uplink and downlink transmission, reconfigure the antennas of the handheld terminal based on the second signaling to obtain reconfigured antenna information.

[0145] In this embodiment, the second signaling includes a second parameter, where the second parameter can be determined according to actual situations and is not limited herein. As an example, the second parameter can be a configuration parameter. In practical applications, the configuration parameter can be enable or disable. Wherein, disable indicates that the network device does not allow the terminal to support the functions of MIMO and uplink and downlink transmission; enable indicates that the network device allows the terminal to support the functions of MIMO and uplink and downlink transmission.

[0146] In the case where the second parameter indicates that the network device does not allow the terminal to support both the MIMO and the functions of simultaneously supporting uplink and downlink transmission, it can be understood that based on the second signaling, no configuration is performed on the antenna of the handheld terminal, that is, in the case where the second parameter indicates that the network device does not allow the terminal to support both the MIMO and the functions of simultaneously supporting uplink and downlink transmission, the second signaling does not affect the normal antenna configuration. As an example, when the second parameter in the second signaling is disable, it does not affect the normal antenna configuration.

[0147] In the case where the second parameter indicates that the network device allows the terminal to support both the MIMO and the functions of simultaneously supporting uplink and downlink transmission, the antenna of the handheld terminal is reconfigured based on the second signaling to obtain the reconfigured antenna information. Wherein, the second signaling can be a signaling configured by the network. As an example, when the signaling simultaneousRxTxInterBandCAPerBandPairWithMIMO configured by the network is enable, when carrier aggregation is performed between n40 and n41, the antenna configuration can be switched from 2t4r to 2t2r.

[0148] In practical applications, for a terminal supporting simultaneous reception and transmission, if it supports carrier aggregation between n40 and n41, the 4Rx requirement for n41 is relaxed, and simultaneous reception and transmission and MIMO operations are allowed to be performed simultaneously on the n40 and n41 frequency bands. Under other conditions, it is still default that n41 forcibly supports 4-antenna reception.

[0149] In one embodiment, the method further includes:

[0150] Reporting the reconfigured antenna information to the network device.

[0151] In this embodiment, reporting the reconfigured antenna information to the network device is to facilitate the network device to understand the antenna information of each terminal under current conditions in real time, so as to facilitate subsequent selection of the optimal antenna configuration under current conditions.

[0152] This application reports to the network through new signaling to indicate whether the terminal has the ability to support MIMO and simultaneous uplink and downlink transmission simultaneously, and in a handheld terminal, relaxes the requirement for 4-antenna reception when carrier aggregation is performed between frequency band n41 and n40, effectively improving the uplink and downlink transmission rates. Specifically, the terminal first reports its capabilities through simultaneousRxTxInterBandCAPerBandPair to indicate whether it supports MIMO and simultaneous uplink and downlink transmission simultaneously. After learning about the terminal capabilities, the network side can perform antenna scheduling for the terminal according to the actual situation to confirm whether the terminal can be configured to use the method of simultaneous MIMO and simultaneous uplink and downlink transmission; for the problem of the mandatory requirement for 4-antenna reception in the n41 frequency band, this requirement is relaxed from the standard. When carrier aggregation is performed between n41 and n40, the restriction of mandatory 4-antenna reception in n41 is lifted and relaxed to 2-antenna reception; when the signaling feedback of the network, simultaneousRxTxInterBandCAPerBandPairWithMIMO, is enabled, an additional statement is made for the downlink antenna configuration and downlink SRS transmission when carrier aggregation is performed between frequency bands n40 and n41 to meet the antenna requirements when the terminal and the network perform simultaneous MIMO and simultaneous uplink and downlink transmission, that is, an additional statement that the number of receiving antennas at this time can be set to "2" or the transceiver antenna requirement at this time is "2t2r".

[0153] To better understand this application, here an actual application scenario is exemplified. The configuration method is specifically a simultaneous uplink and downlink transmission configuration method, and the network device is a base station.

[0154] Regarding the reporting of the terminal's support for uplink MIMO capabilities and support for simultaneous transceiver capabilities is independent, and it is impossible to determine whether the MIMO antenna configuration at this time combines the simultaneous transceiver capabilities. At this time, the terminal may support the two capabilities separately, but it cannot report whether it can support the two capabilities simultaneously. Therefore, there is a possibility of not being able to select the optimal antenna configuration under the current conditions. Configure a new signaling to indicate whether the terminal has the ability to support MIMO and simultaneous uplink and downlink transmission simultaneously. The specific content is as follows:

[0155] The first step: The current terminal can report whether it supports MIMO or simultaneous uplink and downlink transmission, but it cannot report whether it can support both of these capabilities simultaneously. When both capabilities are supported but not simultaneously, it will be determined by the terminal manufacturer's statement regarding the priority of the above two capabilities.

[0156] The second step: Introduce a new signaling to indicate whether the terminal has the function of supporting MIMO and simultaneous uplink and downlink transmission simultaneously. To reduce signaling overhead, this signaling will only be reported when the terminal supports simultaneous uplink and downlink transmission.

[0157] (1) When the terminal supports simultaneous transmission and reception, it reports through this signaling whether the terminal can support MIMO simultaneously.

[0158] 1) If the signaling reports that the terminal can support simultaneous transmission and reception and MIMO at this time, then an antenna configuration method combining simultaneous uplink and downlink with MIMO is adopted.

[0159] 2) If the signaling reports that the terminal cannot support simultaneous transmission and reception and MIMO simultaneously, then the base station performs antenna configuration according to the actual situation. The antenna configuration by the base station according to the actual situation can be understood as the normal antenna configuration method of the base station in the existing network.

[0160] (2) When the terminal does not support simultaneous transmission and reception, this signaling is not reported, and when there is a MIMO requirement, it is configured according to the normal MIMO antenna requirements.

[0161] Regarding the case where the terminal supports both MIMO and simultaneous transmission and reception capabilities, for CA_n40 - n41, since the two sub - carrier frequencies are relatively close, the terminal needs to add additional filters or antennas. In the case of supporting simultaneous transmission and reception capabilities and with an antenna configuration of 2 transmit and 4 receive, the terminal requires at least 6 independent antennas. The method of adding new antennas may be feasible for some terminals, but it is difficult to implement for devices with a small volume such as handheld terminals. To solve this problem, the antenna configuration requirements for some special frequency bands of some current terminals are relaxed, and the specific content is as follows:

[0162] Differentiate the terminals and relax the 4 - receive - antenna requirement for handheld terminals.

[0163] The first step: For terminals supporting simultaneous transmission and reception, if they support carrier aggregation of n40 and n41, then relax the 4Rx requirement for n41 and allow simultaneous transmission and reception and MIMO operations on both the n40 and n41 frequency bands.

[0164] The second step: Under other conditions, it is still default that n41 forcibly supports 4 - antenna reception.

[0165] For easy understanding, an example is given here to illustrate whether the new signaling terminal supports MIMO and simultaneous uplink and downlink transmission at the same time.

[0166] First, the terminal reports its capabilities. When reporting capabilities, specific parameters related to NR carrier aggregation (such as CA-ParametersNR) are reported. When the terminal reports simultaneousRxTxInterBandCAPerBandPair, it means that the terminal supports simultaneous transmission and reception for inter-band NR carrier aggregation of TDD-TDD and TDD-FDD at this time. If the terminal can support simultaneous transmission and reception of NR carrier aggregation and a new reported parameter simultaneousRxTxInterBandCAPerBandPairWithMIMO is added to the parameter CA-ParametersNR. If the parameter reported in CA-ParametersNR contains simultaneousRxTxInterBandCAPerBandPairWithMIMO, it means that the terminal can support both simultaneous uplink and downlink transmission and MIMO capabilities, which can be understood in combination with Table 1.

[0167]

[0168]

[0169]

[0170] Table 1

[0171] simultaneousRxTxInterBandCAPerBandPair: Reports whether the terminal supports simultaneous transmission and reception;

[0172] simultaneousRxTxInterBandCAPerBandPairWithMIMO: Reports whether the terminal supports both simultaneous transmission and reception and MIMO. This capability is reported only when the terminal supports simultaneous transmission and reception. When the terminal does not support simultaneous transmission and reception or does not support both simultaneous transmission and reception and MIMO at the same time, this capability is not reported.

[0173] After the network side confirms that the terminal capabilities can support both uplink and downlink transmission and MIMO capabilities, it performs network configuration on the base station side to decide whether to configure the terminal for simultaneous transmission and reception and MIMO.

[0174]

[0175] Regarding the description of the network side signaling, simultaneousRxTxInterBandCAPerBandPair represents that the terminal configured by the network side supports simultaneous transmission and reception;

[0176] simultaneousRxTxInterBandCAPerBandPairWithMIMO represents whether the terminal can support MIMO and simultaneous uplink and downlink transmission at the same time. enable means that the network side allows the terminal to configure simultaneous support for MIMO and simultaneous uplink and downlink transmission, and disabled means that this capability is not supported.

[0177] For ease of understanding, an example is given here to illustrate the impact of simultaneously supporting MIMO and simultaneous transceiver on the downlink antenna configuration requirements.

[0178] In the standard, the requirement for 4-antenna reception of the handheld terminal n41 during carrier aggregation with n40 is relaxed, stating that when carrier aggregation is performed between n41 and the n41 band, it is not mandatory to require 4-antenna reception for the n41 band.

[0179] MaxMIMO-LayersDL-r16 represents the downlink receive antenna configuration when MIMO is configured for each band.

[0180] When the handheld terminal receives a new command from the network side to configure simultaneousRxTxInterBandCAPerBandPairWithMIMO as enable, then MaxMIMO-LayersDL-r16 for the n41 band during carrier aggregation with n40 is set to 2.

[0181] When the signaling is disable, it has no impact on the antenna configuration.

[0182]

[0183] simultaneousRxTxInterBandCAPerBandPairWithMIMO enable means the MaxMIMO-LayersDL-r16 for n41 if carrier aggregation is configured with band n40 and simultaneous Rx-Tx could be set as ‘2’.

[0184] simultaneousRxTxInterBandCAPerBandPairWithMIMO enable represents that if the carrier aggregation is configured for the n40 band, then the MaxMIMO-LayersDL-r16 of n41 can be set to '2'.

[0185] For ease of understanding, an example is given here to illustrate the impact of simultaneously supporting MIMO and simultaneous transceiver on the downlink SRS transmission.

[0186] Downlink SRS transmission is affected by the number of uplink and downlink transceiver ports of the terminal. After determining that the terminal can support both capabilities, the terminal will reconfigure the antenna and needs to report the new antenna configuration.

[0187] The current terminal capabilities support 2Rx4Tx and 2Rx2Tx capabilities, and there is no need to change the capability part. It only needs to be declared in the protocol that when the signaling simultaneousRxTxInterBandCAPerBandPairWithMIMO configured by the network is enable, when carrier aggregation is performed between n40 and n41, the antenna configuration can be switched from 2t4r to 2t2r.

[0188] When the received signaling is disable, it has no impact on the normal antenna configuration.

[0189]

[0190] simultaneousRxTxInterBandCAPerBandPairWithMIMO

[0191] simultaneousRxTxInterBandCAPerBandPairWithMIMO enable means the supportedSRS-TxPortSwitch for n41 if carrier aggregation is configured with band n40 and simultaneous Rx-Tx could be set as ‘t2r2’.

[0192] simultaneousRxTxInterBandCAPerBandPairWithMIMO enable indicates that if carrier aggregation is configured for band n40 and simultaneous Rx-Tx can be set to ‘t2r2’, then the srs-txportswitch for n41 is supported.

[0193] This application reports to the network through a new signaling to indicate whether the terminal has the ability to support MIMO and simultaneous uplink and downlink transmission; and in a handheld terminal, relax the requirement for 4-antenna reception when carrier aggregation is performed between band n41 and n40. The specific content is as follows:

[0194] The terminal first reports its capabilities through simultaneousRxTxInterBandCAPerBandPair, indicating whether it supports MIMO and simultaneous uplink and downlink transmission capabilities. After learning about the terminal's capabilities, the network side can perform antenna scheduling for the terminal according to the actual situation to confirm whether the terminal can be configured in a way that supports MIMO and simultaneous uplink and downlink transmission simultaneously;

[0195] Regarding the mandatory requirement of 4 - antenna reception for the n41 band, this requirement is relaxed from the standard. When carrier aggregation is performed between n41 and n40, the restriction of mandatory 4 - antenna reception for n41 is lifted and relaxed to 2 - antenna reception;

[0196] When the network signaling feedback simultaneousRxTxInterBandCAPerBandPairWithMIMO is enabled, an additional statement is made regarding the downlink antenna configuration and downlink SRS transmission during carrier aggregation between bands n40 and n41 to meet the antenna requirements for the terminal and the network during simultaneous MIMO and simultaneous uplink and downlink transmission, that is, an additional statement that the number of receiving antennas can be set to "2" at this time or the transceiver antenna requirement is "2t2r" at this time.

[0197] This application effectively improves the uplink and downlink transmission rates by performing antenna configuration according to the optimal solution based on the information reported by the terminal regarding its capabilities of simultaneously supporting MIMO and simultaneous uplink and downlink transmission.
