The embodiment of the disclosure provides a method for transmitting capability information. Referring to fig. 2, fig. 2 is a method for transmitting capability information according to an exemplary embodiment, and as shown in fig. 2, the method includes steps S201 to S202, specifically:

in step S201, the user equipment 101 sends capability information to the network equipment 102, where the capability information is used to indicate the vector error magnitude EVM capability of the user equipment.

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

In some possible implementations, the EVM capability of the user equipment 101 is the same as the protocol definition.

Referring to table 1, the protocol defines different modulation and coding strategies (Modulation and Coding Scheme, MCS) corresponding to different EVM minimum requirements. The larger the modulation order of the MCS, the smaller the required EVM value. The smaller the EVM value, the better the UE transmit signal quality is indicated under the same modulation order.

TABLE 1

MCS index	MCS	Unit (B)	Average EVM
0	Pi/2-BPSK	％	30
1	QPSK	％	17.5
2	16QAM	％	12.5
3	64QAM	％	8
4	256QAM	％	3.5

In some possible implementations, the EVM capability of the user equipment 101 is greater than the protocol requirements, i.e., the EVM capability of the user equipment 101 is stronger, smaller EVM values than the corresponding EVM in the protocol may be supported. Such a powerful user equipment 101 is more tamper resistant.

In some possible embodiments, the capability information is reported in units of the user equipment 101 (i.e. per UE), i.e. different user equipments 101 report their own corresponding capability information to the network equipment 102, respectively. The capability information reported by each UE 101 is applicable to all frequency bands (bands) supported by the UE.

In some possible embodiments, the capability information is reported in units of frequency bands (i.e. per band), that is, each ue 101 reports capability information corresponding to at least one frequency band to the network device 102. The capability information reported by the user equipment 101 is applicable to a single frequency band supporting the capability, such as a set frequency band.

In some possible embodiments, the network device 102 may allocate, when scheduling according to the capability information of the user equipment 101, a resource block close to the guard interval in the system bandwidth to the UE with strong capability, where the UE with strong capability may still perform effective data transmission in the part of the resource block. And allocating the resource blocks in the middle of the system bandwidth to the UEs with weaker capabilities. The guard interval is an interval arranged at two ends of the bandwidth, and the part of the bandwidth occupied by the guard interval cannot be used for data transmission in order to protect the signal quality in the band and inhibit out-of-band radiation.

In some possible embodiments, the network device 102 may configure the MCS of the high modulation order for the UE with high capability to improve the transmission quality when scheduling according to the capability information of the user equipment 101.

In some possible implementations, the network device 102 may configure a high priority for a powerful UE when scheduling according to the capability information of the user equipment 101. For example, in carrier aggregation (Carrier Aggregation, CA), when the capability of the UE to set the frequency band EVM is strong, the UE may configure the carrier within the set frequency band to be the primary carrier preferentially.

In the embodiment of the present disclosure, the network device 102 acquires the EVM capability of the user device 101 according to the capability information reported by the user device 101, so that adaptive scheduling can be performed based on the EVM capability of the user device 101, which not only can promote the rationality of scheduling, but also can fully utilize the capability of the user device 101. The throughput and interference resistance of the whole communication system can be improved by effectively scheduling the user equipment 101 with strong capability.

The embodiment of the disclosure provides a method for transmitting capability information. The method comprises the steps of S201 'to S203', specifically:

In step S201', the user equipment 101 sends capability information to the network device 102, the capability information indicating whether the user equipment 101 has high EVM capability.

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

In step S203', in response to the ue 101 having the high EVM capability, the ue 101 performs data transmission on a resource block close to the guard interval in the system bandwidth corresponding to the network device 102 according to the configuration of the network device 102 by the ue 101.

In some possible implementations, the user equipment 101 is considered to have high EVM capability when the EVM supported by the user equipment 101 is below a preset value.

In some possible implementations, a high EVM capability is used to indicate: among the plurality of modulation and coding strategies MCSs 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.

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

For another example, when the user equipment 101 supports a plurality of MCSs, if the EVM supported at any one MCS is lower than a preset value corresponding to the MCS, the user equipment 101 is considered to have a high EVM capability at the MCS.

In some possible embodiments, as shown in table 1, the preset value corresponding to each MCS may be an average EVM value defined by a protocol; or less than the average EVM value defined by the protocol.

In some possible embodiments, the ue 101 with high EVM capability has better transmission signal quality, which can improve the interference immunity and throughput of the system. As shown in fig. 5, a Resource Block (RB) close to a guard interval is allocated to a UE with strong capability, and the UE can still perform effective data transmission by using the part of the Resource Block.

In some possible implementations, the network device 102 allocates n RBs on both sides of the system bandwidth and close to the guard interval for the high EVM capable user device 101.

In some possible implementations, the value of n may be sized according to the actual scheduled traffic.

In the embodiment 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 high EVM capability, and reasonably allocate the transmission of the UE with the low EVM capability, thereby improving the overall throughput of the system.

The embodiment of the disclosure provides a method for transmitting capability information. The method comprises the steps of S201 'to S203', and specifically:

In step S201", the user equipment 101 transmits capability information to the network device 102, the capability information indicating whether the user equipment 101 has a high EVM capability.

In step S202", the network device 102 configures an MCS with a modulation and coding scheme index value MCS index greater than a set value for the user equipment 101 having high EVM capability according to the capability information.

In step S203", in response to the ue 101 having the high EVM capability, the ue 101 performs uplink transmission using the MCS with the modulation and coding scheme index value MCS index greater than the set value according to the configuration of the network device 102.

In some possible implementations, MCS index has a correspondence with MCS, see schematic of table 1. It will be appreciated that the MCS index values in table 1 are only shown in order and are not limiting of the MCS corresponding MCS index values.

In some possible implementations, the larger the MCS index, the larger the corresponding MCS modulation order. The larger the MCS modulation order, the smaller the EVM of the UE is required.

In some possible implementations, the network device 102, in conjunction with the EVM capabilities of the UE, may configure higher order modulation orders for high EVM capable UEs.

In some possible implementations, a UE with high EVM capability may perform uplink transmission with a higher order MCS according to the MCS configured by the network device 102.

In the embodiment of the present 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 the high transmission signal quality of the UE with high EVM capability to perform scheduling, which is beneficial to improving the throughput and recovering each interference capability of the whole system.

Embodiments of the present disclosure provide a method of receiving capability information that is performed by network device 102. Referring to fig. 3, fig. 3 is a method of receiving capability information according to an exemplary embodiment, and as shown in fig. 3, the method includes steps S301 to S302, specifically:

In step S301, the network device 102 receives capability information sent by the user device 101, where the capability information is used to indicate the vector error magnitude EVM capability of the user device 101.

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

In some possible implementations, the EVM capability of the user equipment 101 is the same as the protocol definition. The EVM for protocol definition can be seen in table 1.

In some possible implementations, the EVM capability of the user equipment 101 is greater than the protocol requirements, i.e., the capability of the user equipment 101 is greater, smaller EVM values than the corresponding EVM in the protocol may be supported.

In some possible implementations, the capability information of the user equipment 101 may reflect its transmitter signal quality. The network device 102 may perform adaptive scheduling according to the capability information of the user device 101.

In an example, the network device 102 may configure an MCS of a high modulation order for a UE with a high capability to improve transmission quality when scheduling according to capability information of the user equipment 101. And configuring the MCS with the low modulation order for the UE with weaker capability.

In the embodiment of the present disclosure, the network device 102 acquires the EVM capability of the user device 101 according to the capability information reported by the user device 101, so that adaptive scheduling can be performed based on the EVM capability of the user device 101, which not only can promote the rationality of scheduling, but also can fully utilize the capability of the user device 101.

Embodiments of the present disclosure provide a method of receiving capability information that is performed by network device 102. The method comprises the steps of S301 to S302, and specifically comprises the following steps:

The capability information is used for indicating EVM capabilities corresponding to all frequency bands supported by the user equipment; or the capability information is used for indicating the corresponding EVM capability of the user equipment in the set frequency band.

In some possible embodiments, the capability information reported by the UE 101 is applicable to all frequency bands (bands) supported by the UE, and the capability information may represent EVM capability in any frequency band supported by the UE 101.

In an example, different user equipment 101 may report respective corresponding capability information to network device 102 in per UE fashion.

In some possible embodiments, the capability information reported by the ue 101 is applicable to a single frequency band supporting the capability, i.e. the capability information may represent EVM capability of a set frequency band for which the ue 101 supports the capability.

In an example, each ue 101 may report capability information corresponding to at least one frequency band of itself to the network device 102 in a per band manner.

In the embodiment of the present disclosure, the network device 102 may learn, according to the capability information reported by the ue 101, the EVM capability corresponding to the ue 101 or the EVM capability corresponding to the ue 101 in the set frequency band.

Embodiments of the present disclosure provide a method of receiving capability information that is performed by network device 102. The method comprises the steps of S301' to S302, and specifically:

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

In some possible implementations, the user equipment 101 with high EVM capability may be that the EVM supported by the user equipment 101 is less than a preset value at the same modulation order.

In some possible implementations, a high EVM capability is used to indicate: among the plurality of modulation and coding strategies MCSs 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 this embodiment, a preset value is set for each MCS.

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

In an example, when the user equipment 101 supports multiple MCSs, the user equipment 101 is considered to have a high EVM capability at any one MCS when the EVM supported at that MCS is lower than a preset value corresponding to that MCS.

In some possible embodiments, the preset value corresponding to each MCS may be an average EVM value defined by a protocol; or less than the average EVM value defined by the protocol.

For example, as shown with reference to table 1, the preset value corresponding to QPSK may be set to 17.5%, or less than 17.5%; the preset value corresponding to 16QAM may be set to 12.5%, or less than 12.5%; the preset value corresponding to 256QAM may be set to 3.5%, or less than 3.5%.

In an example, for MCS of QPSK, the protocol defined EVM is 17.5%, and the preset value is set to 17.5%, for example. When the EVM supported by the user equipment 101 under QPSK is less than 17.5%, the user equipment 101 may be considered to have high EVM capability.

In one example, the preset value is set to 12.25% when the MCS is QPSK. When the EVM supported by the user equipment 101 under QPSK is less than 12.5%, the user equipment 101 may be considered to have high EVM capability.

In some possible implementations, the preset value may be set to correlate to a boost ratio of the corresponding EVM defined by the protocol.

In one example, when the MCS is QPSK, the protocol defined EVM is 17.5%. When the EVM boost ratio supported by the user equipment 101 under QPSK is not less than 30%, the user equipment 101 is considered to have high EVM capability. Namely: the EVM supported by the user equipment 101 under QPSK is smaller than: 17.5% = 12.25% (1-30%) = user equipment 101 is considered to have high EVM capability.

In some possible implementations, a bit for indicating whether the user equipment 101 has high EVM capability is included in the capability information.

In some possible implementations, the user equipment 101 is indicated with 1bit information in the capability information as to whether it has high EVM capability.

In one example, when the 1bit is 1, this indicates that the user equipment 101 has high EVM capability.

In one example, when the 1bit is 0, it indicates that the user equipment 101 does not have high EVM capability.

In the embodiment of the present disclosure, the network device 102 knows whether the user device 101 has the high EVM capability according to the capability information of the user device 101, so that the network device 102 can effectively schedule the user device 101 with the high EVM capability.

Embodiments of the present disclosure provide a method of receiving capability information that is performed by network device 102. Referring to fig. 4, fig. 4 is a method of receiving capability information according to an exemplary embodiment, and as shown in fig. 4, the method includes steps S401 to S402, specifically:

In step S401, the network device 102 receives capability information sent by the user device 101, where the capability information is used to indicate whether the user device 101 has a high EVM capability.

In step S402, the network device 102 allocates, according to the capability information, a resource block close to the guard interval in the system bandwidth to the user device 101 with high EVM capability in the system bandwidth corresponding to the network device 102.

In some possible embodiments, the ue 101 with high EVM capability has better transmission signal quality, which can improve the interference immunity and throughput of the system. And allocating Resource Blocks (RBs) close to the guard interval for the UE with strong capability, wherein the UE can still perform effective data transmission by utilizing the part of resource blocks.

In one example:

When multiple UEs are at a cell edge or have poor channel quality, the network device 102 may allocate system bandwidth (e.g., 20 MHz) according to the EVM capabilities of the different UEs when scheduling resources. For example, as shown in connection with fig. 5, n RBs close to the guard interval in the system bandwidth are preferentially allocated to UEs having high EVM capability; RBs of the middle portion of the system bandwidth are allocated to other UEs.

Embodiments of the present disclosure provide a method of receiving capability information that is performed by network device 102.
