[0002] In a wireless communication system, such as a Long Term Evolution (LTE) system or a 5G New Radio (NR) system, the transmission signal quality of a user equipment (UE) transmitter directly affects the anti-interference capability and throughput of the system, and therefore the UE transmission signal quality is an important transmitter index.

[0003] The vector error magnitude (EVM) is usually used to evaluate the UE transmission signal quality. The minimum requirement for the EVM of a user equipment is defined in the 3rd Generation Partnership Project (3GPP) protocol.

[0062] like Figure 1 As shown in the embodiments of this disclosure, a method for transmitting capability information can be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 102, including a primary carrier unit and one or more secondary carrier units.

[0063] It should be understood that the above wireless communication system 100 can be applied to both low frequency scenarios and high frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for microwave access (WiMAX) communication system, a cloud radio access network (CRAN) system, a future 5th-Generation (5G) system, a new radio (NR) communication system, or a future evolved public land mobile network (PLMN) system, and the like.

[0064] The user equipment 101 shown above can be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a terminal device, and the like. The user equipment 101 can have a wireless transceiving function, and can communicate (e.g., wirelessly communicate) with one or more network devices of one or more communication systems and receive network services provided by the network devices, where the network devices include, but are not limited to, the network device 102.

[0065] The user equipment (UE) 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, and the like.

[0066] The network device 102 can be an access network device (or an access network site). The access network device refers to a device having a network access function, such as a radio access network (RAN) base station and the like. The network device 102 can specifically include a base station (BS), or include a base station and a radio resource management device for controlling the base station, and the like. The network device 102 can also include a relay station (relay device), an access point, and a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, and the like. The network device 102 can be a wearable device or a vehicle-mounted device. The network device 102 can also be a communication chip with a communication module.

[0067] For example, the network device 102 includes, but is not limited to, a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a radio controller under a CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or a CDMA system, a home base station (for example, a home evolved node B, or a home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), or a mobile switching center, and the like.

[0068] A method for transmitting capability information is provided in the embodiments of the present disclosure. Referring to Figure 2 , Figure 2 A method for transmitting capability information is provided in the embodiments of the present disclosure. Referring to Figure 2 the method shown in FIG. 2, the method includes steps S201-S202, and specifically:

[0069] In step S201, the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate the vector error magnitude (EVM) capability of the user equipment.

[0070] In step S202, the network device 102 schedules the user equipment 101 according to the received capability information.

[0071] In some possible implementation manners, the EVM capability of the user equipment 101 is the same as that defined by a protocol.

[0072] Referring to Table 1, the protocol defines different modulation and coding strategies (MCS) corresponding to different minimum requirements of EVM. The greater the modulation order of MCS, the smaller the required EVM value. Under the same modulation order, the smaller the EVM value, the better the quality of the UE transmitted signal.

[0073] Table 1

[0074] MCS index MCS Units Average EVM 0 Pi / 2-BPSK ％ 30 1 QPSK ％ 17.5 2 16QAM ％ 12.5 3 64QAM ％ 8 4 256QAM ％ 3.5

[0075] In some possible implementation manners, the EVM capability of the user equipment 101 is greater than the protocol requirement, that is, the EVM capability of the user equipment 101 is stronger, and can support a smaller EVM value than the corresponding EVM in the protocol. Such a user equipment 101 with strong capability has stronger anti-interference capability.

[0076] In some possible implementation manners, the capability information is reported per UE, that is, different user equipments 101 respectively report their own corresponding capability information to the network device 102. The capability information reported by each user equipment 101 is applicable to all bands supported by the UE.

[0077] In some possible implementation manners, the capability information is reported per band, that is, each user equipment 101 reports the capability information corresponding to at least one band to the network device 102. The capability information reported by the user equipment 101 is applicable to a single band supporting the capability, such as a set band.

[0078] In some possible implementation manners, when scheduling according to the capability information of the user equipment 101, the network device 102 can allocate resource blocks close to the guard interval in the system bandwidth to the UE with strong capability, and the UE with strong capability can still perform effective data transmission in the part of resource blocks. The UE with weak capability is allocated resource blocks in the middle position of the system bandwidth. The guard interval is an interval set at both ends of the bandwidth, and the bandwidth part occupied by the guard interval cannot be used for data transmission, for the purpose of protecting the in-band signal quality and suppressing out-of-band radiation.

[0079] In some possible implementation manners, when scheduling according to the capability information of the user equipment 101, the network device 102 can configure the UE with strong capability with MCS of high modulation order to improve the transmission quality.

[0080] In some possible implementation, the network device 102 can configure high priority for the UE with high capability when scheduling according to the capability information of the user equipment 101. For example, in carrier aggregation (CA), when the UE has high capability in setting frequency band EVM, the UE can be configured to prioritize the carrier in the setting frequency band as the primary carrier.

[0081] In the embodiments of the present disclosure, the network device 102 learns the EVM capability of the user equipment 101 according to the capability information reported by the user equipment 101, and thus can perform adaptive scheduling based on the EVM capability of the user equipment 101, which can improve the rationality of scheduling and fully utilize the capability of the user equipment 101. Effective scheduling of the user equipment 101 with high capability can improve the throughput and anti-interference capability of the entire communication system.

[0082] The embodiments of the present disclosure provide a method for transmitting capability information. The method includes steps S201' to S203', and specifically:

[0083] In step S201', the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0084] In step S202', the network device 102 allocates resource blocks close to the guard interval in the system bandwidth corresponding to the network device 102 to the user equipment 101 with high EVM capability according to the received capability information.

[0085] In step S203', in response to the user equipment 101 having high EVM capability, the user equipment 101 performs data transmission on the resource blocks close to the guard interval in the system bandwidth corresponding to the network device 102 according to the configuration of the network device 102.

[0086] In some possible implementation, when the EVM supported by the user equipment 101 is lower than a preset value, the user equipment 101 is considered to have high EVM capability.

[0087] In some possible implementation, the high EVM capability is used to indicate that, in a plurality of modulation and coding strategies (MCS) supported by the user equipment 101, the EVM supported by the user equipment 101 under at least one MCS is lower than a preset value corresponding to the MCS.

[0088] For example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under each MCS is lower than a preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability.

[0089] For another example, when the user equipment 101 supports multiple MCSs, if the EVM supported by the user equipment 101 at any MCS is lower than the preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability at the MCS.

[0090] In some possible implementation, in combination with Table 1, the preset value corresponding to each MCS can be the average EVM value defined by the protocol, or less than the average EVM value defined by the protocol.

[0091] In some possible implementation, the user equipment 101 with high EVM capability has better transmission signal quality, and can improve the anti-interference capability and throughput of the system. In combination with Figure 5 As shown in Table 2, the UE with high capability is allocated the resource blocks (RBs) close to the guard interval, and the UE can still perform effective data transmission by using the resource blocks.

[0092] In some possible implementation, the network device 102 allocates n RBs close to the guard interval on both sides of the system bandwidth for the user equipment 101 with high EVM capability.

[0093] In some possible implementation, the value of n can be determined according to the actual amount of traffic to be scheduled.

[0094] In the embodiments of the present disclosure, the network device 102 performs adaptive scheduling in combination with the EVM capability of the user equipment 101, so as to fully utilize the anti-interference performance of the user equipment 101 with high EVM capability, and reasonably allocate the transmission of the UE with low EVM capability, thereby improving the overall throughput of the system.

[0095] The embodiments of the present disclosure provide a method for transmitting capability information. The method includes steps S201”-S203”, and specifically:

[0096] In step S201”, the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0097] In step S202”, the network device 102 configures, according to the capability information, a modulation and coding strategy index value MCS index greater than a set value for the user equipment 101 with high EVM capability.

[0098] In step S203”, in response to the user equipment 101 having high EVM capability, the user equipment 101 performs uplink transmission by using the modulation and coding strategy index value MCS index greater than the set value, according to the configuration of the network device 102.

[0099] In some possible implementation, the user equipment 101 is considered to have high EVM capability when the EVM supported by the user equipment 101 is lower than a preset value.

[0100] In some possible implementation, the high EVM capability is used to indicate that the EVM supported by the user equipment 101 at at least one modulation and coding strategy (MCS) is lower than a preset value corresponding to the MCS among a plurality of MCSs supported by the user equipment 101.

[0101] For example, the user equipment 101 is considered to have high EVM capability when the EVM supported by the user equipment 101 at each of a plurality of MCSs is lower than a preset value corresponding to the MCS.

[0102] For another example, the user equipment 101 is considered to have high EVM capability at a certain MCS when the EVM supported by the user equipment 101 at the certain MCS is lower than a preset value corresponding to the certain MCS among a plurality of MCSs supported by the user equipment 101.

[0103] In some possible implementation, the MCS index has a corresponding relationship with the MCS, which can be referred to Table 1. It can be understood that the MCS index values in Table 1 are only used for sequence illustration, and are not a limitation on the MCS index values corresponding to the MCS.

[0104] In some possible implementation, the larger the MCS index is, the larger the modulation order of the corresponding MCS is. The larger the modulation order of the MCS is, the smaller the EVM of the UE is required.

[0105] In some possible implementation, the network device 102 can configure a higher order modulation order for the UE with high EVM capability in combination with the EVM capability of the UE.

[0106] In some possible implementation, the UE with high EVM capability can perform uplink transmission by using a high order MCS according to the MCS configured by the network device 102.

[0107] In the embodiments of the present disclosure, the network device 102 fully utilizes the high anti-interference capability and high transmission signal quality of the UE with high EVM capability to perform scheduling in combination with the capability information of the user equipment 101, which is beneficial to improving the throughput and anti-interference capability of the whole system.

[0108] The embodiments of the present disclosure provide a method for receiving capability information, which is performed by the network device 102. Referring to Figure 3 , Figure 3 Fig. 1 is a flowchart of a method for receiving capability information according to an example embodiment, which includes steps S301-S302, and specifically: Figure 3

[0109] ​At step S301, the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate the vector error magnitude (EVM) capability of the user equipment 101.

[0110] At step S302, the network device 102 schedules the user equipment 101 based on the capability information.

[0111] In some possible implementation manners, the EVM capability of the user equipment 101 is the same as that defined by a protocol. The protocol-defined EVM can refer to Table 1.

[0112] In some possible implementation manners, the EVM capability of the user equipment 101 is greater than the protocol requirement, that is, the capability of the user equipment 101 is stronger, and the user equipment 101 can support a smaller EVM value than the corresponding EVM in the protocol.

[0113] In some possible implementation manners, the capability information of the user equipment 101 can reflect the signal quality of the transmitter of the user equipment 101. The network device 102 can perform adaptive scheduling according to the capability information of the user equipment 101.

[0114] In an example, when scheduling according to the capability information of the user equipment 101, the network device 102 can configure a high modulation order MCS for a UE with strong capability, to improve the transmission quality. The network device 102 can configure a low modulation order MCS for a UE with weak capability.

[0115] In the embodiments of the present disclosure, the network device 102 learns the EVM capability of the user equipment 101 according to the capability information reported by the user equipment 101, and can perform adaptive scheduling based on the EVM capability of the user equipment 101, which can improve the rationality of scheduling and fully utilize the capability of the user equipment 101.

[0116] The embodiments of the present disclosure provide a method for receiving capability information, which is performed by the network device 102. The method includes steps S301-S302, and specifically:

[0117] At step S301, the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate the vector error magnitude (EVM) capability of the user equipment 101.

[0118] At step S302, the network device 102 schedules the user equipment 101 based on the capability information.

[0119] The capability information is used to indicate the EVM capability corresponding to all frequency bands supported by the user equipment; or the capability information is used to indicate the EVM capability corresponding to a set frequency band of the user equipment.

[0120] In some possible implementation, the capability information reported by the user equipment 101 is applicable to all bands supported by the UE, i.e., the capability information can represent the EVM capability of any band supported by the user equipment 101.

[0121] In an example, different user equipment 101 can report respective corresponding capability information to the network device 102 in a per UE manner.

[0122] In some possible implementation, the capability information reported by the user equipment 101 is applicable to a single band supporting the capability, i.e., the capability information can represent the EVM capability of the set band supported by the user equipment 101.

[0123] In an example, each user equipment 101 can report capability information corresponding to at least one band thereof to the network device 102 in a per band manner.

[0124] In the embodiments of the present disclosure, the network device 102 can obtain the EVM capability of the user equipment 101 or the EVM capability of the set band corresponding to the user equipment 101 according to the capability information reported by the user equipment 101.

[0125] The embodiments of the present disclosure provide a method for receiving capability information, which is performed by the network device 102. The method comprises steps S301' to S302, and specifically:

[0126] In step S301', the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0127] In step S302, the network device 102 schedules the user equipment 101 based on the capability information.

[0128] In some possible implementation, the user equipment 101 with high EVM capability can be that the EVM supported by the user equipment 101 is less than a preset value under the same modulation order.

[0129] In some possible implementation, the high EVM capability is used to indicate that, in a plurality of modulation and coding strategies (MCS) supported by the user equipment 101, the EVM supported by the user equipment 101 under at least one MCS is lower than a preset value corresponding to the MCS. That is, in the embodiment, a preset value is set for each MCS.

[0130] In an example, when the user equipment 101 supports a plurality of MCSs and the EVM supported under each MCS is lower than the preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability.

[0131] In an example, the user equipment 101 supports multiple MCSs, and the EVM supported by the user equipment 101 at any MCS is lower than a preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability at the MCS.

[0132] In some possible implementation, the preset value corresponding to each MCS can be an average EVM value defined by the protocol, or less than the average EVM value defined by the protocol.

[0133] For example, referring to Table 1, the preset value corresponding to QPSK can be set as 17.5%, or less than 17.5%; the preset value corresponding to 16QAM can be set as 12.5%, or less than 12.5%; and the preset value corresponding to 256QAM can be set as 3.5%, or less than 3.5%.

[0134] In an example, for the MCS being QPSK, the EVM defined by the protocol is 17.5%, and the preset value is set as 17.5% for example. When the EVM supported by the user equipment 101 at QPSK is less than 17.5%, the user equipment 101 is considered to have high EVM capability.

[0135] In an example, for the MCS being QPSK, the preset value is set as 12.25%. When the EVM supported by the user equipment 101 at QPSK is less than 12.5%, the user equipment 101 is considered to have high EVM capability.

[0136] In some possible implementation, the preset value can be set as a promotion ratio related to the corresponding EVM defined by the protocol.

[0137] In an example, for the MCS being QPSK, the EVM defined by the protocol is 17.5%. When the promotion ratio of the EVM supported by the user equipment 101 at QPSK is not less than 30%, the user equipment 101 is considered to have high EVM capability. That is, when the EVM supported by the user equipment 101 at QPSK is less than 17.5%*(1-30%) = 12.25%, the user equipment 101 is considered to have high EVM capability.

[0138] In some possible implementation, the capability information includes a bit used to indicate whether the user equipment 101 has high EVM capability.

[0139] In some possible implementation, 1 bit information in the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0140] In an example, when the 1 bit is 1, it indicates that the user equipment 101 has high EVM capability.

[0141] In an example, the 1 bit is 0, indicating that the user equipment 101 does not have high EVM capability.

[0142] In the embodiments of the present disclosure, the network device 102 learns whether the user equipment 101 has high EVM capability according to the capability information of the user equipment 101, so that the network device 102 can effectively schedule the user equipment 101 with high EVM capability.

[0143] In the embodiments of the present disclosure, a method for receiving capability information is provided, which is performed by the network device 102. Referring to Figure 4 , Figure 4 A method for receiving capability information is shown according to an example embodiment, as shown in FIG. 4, the method includes steps S401-S402, specifically: Figure 4

[0144] In step S401, the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0145] In step S402, the network device 102 allocates resource blocks close to the guard interval in the system bandwidth corresponding to the network device 102 for the user equipment 101 with high EVM capability according to the capability information.

[0146] In some possible implementation manners, the user equipment 101 with high EVM capability can be that, under the same modulation order, the EVM supported by the user equipment 101 is less than a preset value.

[0147] In some possible implementation manners, the high EVM capability is used to indicate that, in a plurality of modulation and coding strategies (MCS) supported by the user equipment 101, the EVM supported by the user equipment 101 under at least one MCS is lower than a preset value corresponding to the MCS. That is, in the embodiment, a preset value is set for each MCS.

[0148] In an example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under each MCS is lower than the preset value corresponding to the MCS, it is considered that the user equipment 101 has high EVM capability.

[0149] In an example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under any one of the MCSs is lower than the preset value corresponding to the MCS, it is considered that the user equipment 101 has high EVM capability under the MCS.

[0150] In some possible implementation manners, in combination with Table 1, the preset value corresponding to each MCS can be an average EVM value defined by a protocol; or less than the average EVM value defined by the protocol.

[0151] ​In some possible implementation manners, the user equipment 101 with high EVM capability has better transmission signal quality, and can improve the interference resistance capability and throughput of the system. The user equipment 101 with high capability is allocated resource blocks RB close to the guard interval, and the user equipment 101 can still perform effective data transmission by using the resource blocks.

[0152] In some possible implementation manners, the network device 102 allocates n RB close to the guard interval on both sides of the system bandwidth to the user equipment 101 with high EVM capability.

[0153] In some possible implementation manners, the value of n can be determined according to the actual amount of services scheduled.

[0154] In an example,

[0155] When multiple user equipments are at the cell edge or have poor channel quality, the network device 102 can allocate the system bandwidth (for example, 20 MHz) according to the EVM capabilities of different user equipments when scheduling resources. For example, as shown in FIG. 2, n RB close to the guard interval in the system bandwidth are preferentially allocated to the user equipment with high EVM capability; and the RB in the middle part of the system bandwidth are allocated to other user equipments. Figure 5

[0156] In the embodiments of the present disclosure, the network device 102 performs adaptive scheduling in combination with the EVM capabilities of the user equipment 101, to fully utilize the interference resistance performance of the user equipment 101 with high EVM capability, and reasonably allocate the transmission of the user equipment 101 with low EVM capability, thereby improving the overall throughput of the system.

[0157] In the embodiments of the present disclosure, a method for receiving capability information is provided, which is performed by the network device 102. Referring to Figure 6 Figure 6 A method for receiving capability information is shown according to an example embodiment, as shown in FIG. 6, the method comprises steps S601-S602, and specifically: Figure 6

[0158] In step S601, the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0159] In step S602, the network device 102 configures a modulation and coding strategy index value MCS greater than a set value for the user equipment 101 with high EVM capability according to the capability information.

[0160] In some possible implementation manners, the user equipment 101 with high EVM capability can be the user equipment 101 that supports an EVM less than a preset value at the same modulation order.

[0161] ​​​In some possible implementations, high EVM capability is used to indicate that, among the multiple modulation and coding schemes (MCSs) supported by user equipment 101, the EVM supported by user equipment 101 in at least one MCS is lower than a preset value corresponding to that MCS. That is, in this implementation, each MCS is set with a preset value.

[0162] In one example, when user equipment 101 supports multiple MCSs, if the EVM supported under each MCS is lower than the preset value corresponding to that MCS, then user equipment 101 is considered to have high EVM capability.

[0163] In one example, when user equipment 101 supports multiple MCSs, if the EVM supported under any MCS is lower than the preset value corresponding to that MCS, the user equipment 101 is considered to have high EVM capability under that MCS.

[0164] In some possible implementations, the preset value corresponding to each MCS may be the average EVM value defined by the protocol; or it may be less than the average EVM value defined by the protocol.

[0165] In some possible implementations, there is a correspondence between MCS index and MCS, as illustrated in Table 1. It should be understood that the MCS index values ​​in Table 1 are for illustrative purposes only and do not represent a limitation on the corresponding MCS index values.

[0166] In some possible implementations, a larger MCS index corresponds to a larger MCS modulation order. A larger MCS modulation order requires a smaller UE EVM.

[0167] In some possible implementations, network device 102, in conjunction with the UE's EVM capability, can configure a higher modulation order for UEs with high EVM capability.

[0168] In some possible implementations, the UE can perform uplink transmission using a higher-order MCS, depending on the MCS configured in the network device 102.

[0169] In this embodiment of the disclosure, the network device 102 combines the capability information of the user equipment 101 and makes full use of the high anti-interference capability and high transmission signal quality of the UE with high EVM capability for scheduling, which is beneficial to improving the throughput and anti-interference capability of the entire system.

[0170] This disclosure provides a method for receiving capability information, executed by network device 102. (Refer to...) Figure 7 , Figure 7 This is a method for receiving capability information according to an exemplary embodiment, such as... Figure 7 As shown, the method includes steps S701 to S702, specifically:

[0171] At step S701, the network device 102 receives the capability information sent by the user equipment 101, and the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0172] At step S702, in response to the capability information indicating that the user equipment 101 supports high EVM capability in the set frequency band, and the set frequency band is a member carrier in carrier aggregation, the priority of the carrier in the set frequency band as a primary carrier is configured to be higher than the priority of the carrier in the non-set frequency band as a primary carrier.

[0173] In some possible implementation manners, the user equipment 101 with high EVM capability can be that, under the same modulation order, the EVM supported by the user equipment 101 is less than a preset value.

[0174] In some possible implementation manners, the high EVM capability is used to indicate that, in a plurality of modulation and coding strategies (MCS) supported by the user equipment 101, the EVM supported by the user equipment 101 under at least one MCS is lower than a preset value corresponding to the MCS. That is, in the embodiment, a preset value is set for each MCS.

[0175] In an example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under each MCS is lower than a preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability.

[0176] In an example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under any one of the MCSs is lower than a preset value corresponding to the MCS, the user equipment 101 is considered to have high EVM capability under the MCS.

[0177] In some possible implementation manners, the preset value corresponding to each MCS can be an average EVM value defined by a protocol, or less than the average EVM value defined by the protocol.

[0178] In some possible implementation manners, the embodiment can be applicable to a scenario in which the UE reports EVM per band.

[0179] In some possible implementation manners, in a CA scenario, if a component carrier (CC) in CA is on a set frequency band, the CC can be configured to have high priority as a primary carrier, and the CC is preferred as a primary carrier of the CA.

[0180] In the embodiment of the present disclosure, the network device 102 combines the capability information of the user equipment 101, and can configure high priority of a carrier in a set frequency band as a primary carrier when scheduling in a CA scenario.

[0182] In step S801, the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate the vector error magnitude EVM capability of the user equipment 101.

[0183] In the embodiments of the present disclosure, the user equipment 101 reports its own capability information to the network device 102, so that the network device 102 can learn the EVM capability of the user equipment 101, so that the network device 102 can perform adaptive scheduling based on the EVM capability of the user equipment 101.

[0189] In some possible implementation manners, 1 bit information in the capability information is used to indicate whether the user equipment 101 has high EVM capability.

[0190] In some possible implementation manners, the high EVM capability is used to indicate that, in a plurality of modulation and coding strategies MCS supported by the user equipment 101, the EVM supported by the user equipment 101 under at least one MCS is lower than a preset value corresponding to the MCS.

[0191] In an example, when the user equipment 101 supports a plurality of MCSs, and the EVM supported under each MCS is lower than the preset value corresponding to the MCS, the user equipment 101 reports to the network device 102 that the user equipment 101 has high EVM capability. ​

[0192] In an example, when the user equipment 101 supports multiple MCSs, and the EVM supported by the user equipment 101 at any MCS is lower than the preset value corresponding to the MCS, the user equipment 101 reports to the network device 102 that the user equipment 101 has high EVM capability at the MCS.

[0193] In some possible implementation manners, in combination with Table 1, the preset value corresponding to each MCS can be an average EVM value defined by a protocol, or less than the corresponding average EVM value defined by the protocol.

[0194] A method for sending capability information is provided in the embodiments of the present disclosure, and is executed by the user equipment 101. The method includes steps S801-S802, and specifically:

[0195] In step S801, the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate the vector error magnitude EVM capability of the user equipment 101.

[0196] In step S802, in response to the user equipment 101 having high EVM capability, the user equipment 101 performs data transmission on resource blocks close to a guard interval in the system bandwidth corresponding to the network device 102 according to the configuration of the network device 102.

[0197] In some possible implementation manners, the network device 102 allocates, according to the capability information, resource blocks close to a guard interval in the system bandwidth to the user equipment 101 having high EVM capability in the system bandwidth corresponding to the network device 102.

[0198] In the embodiments of the present disclosure, the network device 102 performs adaptive scheduling in combination with the EVM capability of the user equipment 101, to fully utilize the anti-interference performance of the user equipment 101 having high EVM capability, and reasonably allocate the transmission of the user equipment 101 having low EVM capability, thereby improving the overall throughput of the system.

[0199] A method for sending capability information is provided in the embodiments of the present disclosure, and is executed by the user equipment 101. The method includes steps S801-S802', and specifically:

[0200] In step S801, the user equipment 101 sends capability information to the network device 102, and the capability information is used to indicate the vector error magnitude EVM capability of the user equipment 101.

[0201] In step S802', in response to the user equipment 101 having high EVM capability, the user equipment 101 performs uplink transmission by using an MCS with a modulation and coding strategy index value MCS index greater than a set value according to the configuration of the network device 102.

[0202] In some possible implementation, the network device 102 configures a modulation and coding strategy index value (MCS index) of a MCS greater than a set value for the user equipment 101 with high EVM capability according to the capability information.

[0203] In some possible implementation, the MCS index has a corresponding relationship with the MCS, which can be seen from Table 1.

[0204] In some possible implementation, the greater the MCS index is, the greater the corresponding MCS modulation order is. The greater the MCS modulation order is, the smaller the EVM of the UE is required.
