Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to a configuration method, a user equipment, a network equipment, a communication system, and a storage medium. Background Art

[0002] The ULFPTx Mode (UL full power Tx Mode) is an enhancement in Release 16. In Release 15, due to limitations in the codebook and PUSCH (Physical Uplink Shared Channel) power control, full power transmission (e.g., 26 dBm) could not be achieved in some cases, which affected the uplink coverage and rate.

[0003] However, in all cases, not every PA (Power Amplifier) can necessarily reach the maximum output power corresponding to the terminal's power class. Release 16 designs different uplink full power transmission schemes, i.e., different ULFPTx Modes, for terminals with different PA capabilities, enabling dual uplink terminals to transmit at full uplink power (26 dBm) above the cell edge. Compared with Release 15, some terminals use 23 dBm single transmission due to protocol restrictions, which can improve the uplink coverage by 2 - 3 dB. This function can ensure that dual uplink terminals transmit uplink signals at full power, ensuring coverage, and is one of the key technologies for UEs (User Equipment) in Release 16. The current full power transmission of UEs is mainly divided into three modes: fullpower (full power transmission mode 0), fullpowerMode1 (full power transmission mode 1), and fullpowerMode2 (full power transmission mode 2). In the relevant Release 18 coverage enhancement discussion, the RAN4 conclusion shows that the ability to transmit at full power needs to be considered when reporting power backoff.

[0004] To achieve more reasonable uplink power scheduling, the UE needs to report the current power class change amount (which can be increased or decreased). Therefore, the base station needs to perform reasonable scheduling on the UE based on the reported power class change information. However, in the relevant protocol standards, the full - power capability and the power class capability are reported separately, and the UE will configure the corresponding P - max (power maximum) information and the corresponding full - power transmission mode based on the current network configuration. However, if the power class change information of the UE is reported but the full - power transmission mode is not adjusted, unreasonable scheduling behavior may occur due to the UE's power backoff while the full - power mode remains unchanged. Summary of the Invention

[0048] To make the objectives, technical solutions, and advantages of the present disclosure more apparent and understandable, the present disclosure will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0049] Figure 1 A flowchart of some embodiments of the configuration method according to the present disclosure, which is executed by a UE. The UE may also be a terminal, which is a device with wireless transceiver functions and can communicate with one or more CNs (core networks) via an access network device in an (R)AN ((radio) access network). It can be deployed on land, including indoor or outdoor, handheld, wearable, or vehicle-mounted; it can also be deployed on water, such as on a ship; it can also be deployed in the air, such as on an airplane, a balloon, or a satellite, etc. The terminal device may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a VR (virtual reality) terminal device, an AR (augmented reality) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0050] In step 110, receive first configuration information, where the first configuration information includes configuring at least one full-power transmission mode for the user equipment at at least one power level.

[0051] In some embodiments, the UE receives the first configuration information sent by a network device such as a base station.

[0052] In some embodiments, the first configuration information is configured within the Config (configuration) information of the PUSCH.

[0053] In some embodiments, the at least one power level includes at least one of PC3 (Power Level 3), PC2 (Power Level 2), and PC1.5 (Power Level 1.5).

[0054] In some embodiments, the at least one full - power transmission mode includes one or two of fullpower (Full - power Transmission Mode 0), fullpowerMode1 (Full - power Transmission Mode 1), and fullpowerMode2 (Full - power Transmission Mode 2).

[0055] In step 120, according to the first configuration information, configure the full - power transmission mode.

[0056] For example, when the UE is at PC3, it is configured with one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0057] When the UE is at PC2, it is configured with one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0058] When the UE is at PC1.5, it is configured with one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0059] Alternatively, when the UE is at PC3, it is configured with any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0060] When the UE is at PC2, it is configured with any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0061] When the UE is at PC1.5, it is configured with any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0062] If the power level of the UE changes, since the UE can configure at least one full - power transmission mode, the transmission mode can be switched.

[0063] In the above - mentioned embodiments, after receiving the first configuration information, the UE configures at least one full - power transmission mode according to the first configuration information, which can reduce the unreasonable scheduling problem caused by the UE's power back - off but the unchanged full - power transmission mode.

[0064] In some embodiments of the present disclosure, the UE receives indication information, where the indication information includes an indication of the full-power transmission mode selected by the user equipment.

[0065] For example, when the UE receives configuration information that configures one of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is determined by an indication sent by a network device such as a base station. This indication information is configured in DCI (Downlink Control Information).

[0066] For another example, when the UE receives configuration information that configures two of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is determined by an indication sent by a network device such as a base station. This indication information is configured in DCI.

[0067] For another example, when the UE receives configuration information that configures one of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is the full-power transmission mode selected by the UE itself.

[0068] For another example, when the UE receives configuration information that configures two of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is the full-power transmission mode selected by the UE itself.

[0069] In the above embodiments, after the UE receives the first configuration information and performs relevant configurations, which full-power transmission mode to specifically use subsequently can be achieved either by receiving an indication or by the UE itself deciding which full-power transmission mode to use, so that when the UE power is backed off, the full-power mode is adaptively changed, facilitating reasonable scheduling by the base station.

[0070] In some embodiments of the present disclosure, the configuration of the UE full-power transmission mode can be configured by adding new RRC (Radio Resource Control) parameters, and these RRC parameters should be configured in PUSCH-Config.

[0071] For example, three fields are added to the RRC parameters. When the base station sends configuration information to the UE, it can choose to configure one field, two fields, or three fields.

[0072] The first newly added field, with a parameter name such as ul-FullPowerTransmissionPC3-r18, indicates that the base station supports configuring the UE of PC3 to one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0073] The second newly added field, with a parameter name such as ul-FullPowerTransmissionPC2-r18, indicates that the base station supports configuring the UE of PC2 to one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0074] The third newly added field, with a parameter name such as ul-FullPowerTransmissionPC1dot5-r18, indicates that the base station supports configuring the UE of PC1.5 to one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0075] In some embodiments, the PUSCH-Config information element is, for example:

[0076]

[0077]

[0078] In the above embodiments, if only one field is selected for configuration, the UE only needs to switch to the full-power mode when at the PC level corresponding to this field, and other modes will not be switched; if three fields are configured, the UE can switch freely.

[0079] In the above embodiments, which transmission mode the UE specifically selects to use is determined by itself, or is indicated by network devices such as the base station.

[0080] In some embodiments of the present disclosure, the configuration of the UE full-power transmission mode has more than one optional full-power mode in the newly added RRC parameters.

[0081] For example, when adding three fields to the RRC parameters, when the network device sends configuration information to the UE, it can choose to configure one field, two fields, or three fields.

[0082] The first newly added field, with a parameter name such as ul-FullPowerTransmissionPC3-r18, indicates that the network device supports configuring the UE of PC3 to any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0083] The second newly added field, with a parameter name such as ul-FullPowerTransmissionPC2-r18, indicates that the network device supports configuring the UE of PC2 to any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0084] The third newly added field, with a parameter name such as ul-FullPowerTransmissionPC1dot5-r18, indicates that the network device supports configuring the UE of PC1.5 to any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0085] In some embodiments, the PUSCH-Config information element is, for example:

[0086]

[0087]

[0088] In the above embodiments, if only one field is selected for configuration, the UE only needs to switch to the full-power mode at this PC level, and other modes will not be switched; if three fields are configured, the UE can switch freely.

[0089] In the above embodiments, which transmission mode the UE specifically selects is indicated by the network device such as the base station according to the network conditions through DCI, or is determined by the UE itself.

[0090] In some embodiments, the network device sends the first configuration information to the user equipment without sending ulpowerControl (uplink power control) to the user equipment. The ulpowerControl is configured in the BWP (Bandwidth Part, partial bandwidth)-UplinkDedicated (uplink dedicated) parameter of the Config information of PUSCH.

[0091] For example, if the base station configures ulpowerControl in BWP-UplinkDedicated containing PUCCH-Config, the above-mentioned respective fields are not configured.

[0092] Considering that if the full-power transmission mode changes, it is possible that no reasonable configuration information can be found in the corresponding TPMI (Transmit precoding matrix indicator) table. For example, as shown in Table 1:

[0093] Table 1

[0094]

[0095] In Table 1 above, there is no corresponding fullyAndPartialAndNonCoherent (fully, partially, and non-coherent) antenna coherence in this mode. If switched to this full-power transmission mode, but the antenna coherence is still fullyAndPartialAndNonCoherent, it will result in a situation where there is no corresponding configuration.

[0096] Figure 2 It is a flowchart of another embodiment of the configuration method of the present disclosure, which is executed by the UE.

[0097] In step 210, receive the second configuration information, where the second configuration information includes the corresponding codebook subset type of the user equipment in at least one full-power transmission mode.

[0098] The codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent.

[0099] In step 220, configure the corresponding codebook subset type according to the second configuration information.

[0100] For example, in the fullpower mode, the UE can select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent.

[0101] In the fullpowerMode1 mode, the UE can select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent.

[0102] In the full - power mode 1, the UE can select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent.

[0103] In the above - mentioned embodiments, when the UE power level changes, the full - power transmission mode also changes. Through the second configuration information, the change of the codebook subset mode is realized, which can reduce the misconfiguration problem of the TPMI table and improve the accuracy of network device scheduling and management.

[0104] In some embodiments, the correct scheduling and management of network devices are achieved by adding RRC parameters. For example, three new fields are added to the RRC parameters. When network devices such as base stations send configuration information to the UE, they can choose to configure one field, two fields, or three fields.

[0105] For the first new field, the parameter name is, for example, codebookSubsetwithfullpower - r18. This field indicates that the network device supports the UE in the full - power mode, and its antenna coherence can be selected from the following three: fullyAndPartialAndNonCoherent, partialAndNonCoherent, nonCoherent.

[0106] For the second new field, the parameter name is, for example, codebookSubsetwithfullpowerMode1 - r18. This field indicates that the network device supports the UE in the full - power mode 1, and its antenna coherence can be selected from the following three: fullyAndPartialAndNonCoherent, partialAndNonCoherent, nonCoherent.

[0107] For the third new field, the parameter name is, for example, codebookSubsetwithfullpowerMode2 - r18. This field indicates that the network device supports the UE in the full - power mode 2, and its antenna coherence can be selected from the following three: fullyAndPartialAndNonCoherent, partialAndNonCoherent, nonCoherent.

[0108] In some embodiments, the PUSCH - Config information element is, for example:

[0109]

[0110] In the above embodiments, if only one field is selected for configuration, the UE needs to perform antenna coherence switching only when in this transmission mode, and no switching will occur in other transmission modes; if three fields are configured, switching can be performed arbitrarily.

[0111] In some embodiments, in combination with the existing TPMI table corresponding to the full-power mode, the optional items of antenna coherence can be further streamlined. That is, when the user equipment is in full-power transmission mode 0 or full-power transmission mode 2, the codebook subset types include one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent; and when the user equipment is in full-power transmission mode 1, the codebook subset types include one of partialAndNonCoherent and NonCoherent.

[0112] Compared with the previous embodiment, there are only two choices for antenna coherence in the fullpowerMode1 mode, namely partialAndNonCoherent and nonCoherent. The PUSCH-Config information element is, for example:

[0113] codebookSubsetwithfullpower-r18

[0114] ENUMERATED {fullyAndPartialAndNonCoherent,partialAndNonCoherent,nonCoherent} OPTIONAL,--Cond codebookBased codebookSubsetwithfullpowerMode1-r18

[0115] ENUMERATED{partialAndNonCoherent,nonCoherent}OPTIONAL,--Cond codebookBasedcodebookSubsetwithfullpowerMode2-r18

[0116] ENUMERATED {fullyAndPartialAndNonCoherent,partialAndNonCoherent,nonCoherent} OPTIONAL,--Cond codebookBased

[0117] Through the above embodiments, the problem of TPMI configuration caused by the change of the UE power level is solved.

[0118] Figure 3 The flowchart of another embodiment of the configuration method of the present disclosure is executed by a network device, such as a base station, a relay node, etc.

[0119] In step 310, first configuration information is generated, where the first configuration information includes configuring at least one full-power transmission mode for the user equipment at at least one power level.

[0120] In some embodiments, the at least one power level includes at least one of power level 3, power level 2, and power level 1.5.

[0121] In some embodiments, the at least one full-power transmission mode includes one or two of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2.

[0122] In some embodiments, the first configuration information includes at least one of the following: supporting configuring the UE with PC3 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring the UE with PC2 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring the UE with PC1.5 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2.

[0123] In some embodiments, the first configuration information includes at least one of the following: supporting configuring the UE with PC3 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring the UE with PC2 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring the UE with PC1.5 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2.

[0124] After the UE capability report, this step considers the specific configurations of network devices such as the base station.

[0125] In step 320, send the first configuration information to the user equipment.

[0126] In some embodiments, the first configuration information is configured within the Config information of the PUSCH. For example, the network device configures the UE by adding new RRC parameters, and these RRC parameters should be configured in PUSCH-Config.

[0127] In some embodiments, three new fields are added to the RRC parameters. When the base station sends configuration information to the UE, it can choose to configure one field, two fields, or three fields.

[0128] For the first new field, the parameter name is, for example, ul-FullPowerTransmissionPC3-r18. This field indicates that the base station supports configuring the UE with PC3 as one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0129] For the second new field, the parameter name is, for example, ul-FullPowerTransmissionPC2-r18. This field indicates that the base station supports configuring the UE with PC2 as one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0130] For the third new field, the parameter name is, for example, ul-FullPowerTransmissionPC1dot5-r18. This field indicates that the base station supports configuring the UE with PC1.5 as one of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0131] In some embodiments, for the first new field, the parameter name is, for example, ul-FullPowerTransmissionPC3-r18. This field indicates that the network device supports configuring the UE with PC3 as any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0132] The second newly added field, with a parameter name such as ul-FullPowerTransmissionPC2-r18, indicates that the network device supports configuring the UE of PC2 to any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0133] The third newly added field, with a parameter name such as ul-FullPowerTransmissionPC1dot5-r18, indicates that the network device supports configuring the UE of PC1.5 to any two of the three transmission modes: fullpower, fullpowerMode1, and fullpowerMode2.

[0134] In the above embodiments, the network device sends the first configuration information to the UE so that the UE can configure at least one full-power transmission mode at at least one power level, which can reduce the unreasonable scheduling problem caused by the UE power back-off but no change in the full-power transmission mode.

[0135] In some other embodiments of the present disclosure, the network device also sends indication information to the user equipment, where the indication information includes indicating the full-power transmission mode selected by the user equipment.

[0136] For example, the network device sends DCI indication to the UE according to the network status, and the selected full-power transmission mode of the UE is carried in the indication. Although the UE can select one transmission mode or any two transmission modes from the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2, which specific transmission mode to select is determined by the network device.

[0137] In some embodiments, which specific transmission mode the UE selects can also be determined by itself.

[0138] In some embodiments, when ulpowerControl is not sent to the user equipment, the first configuration information is sent to the user equipment. The ulpowerControl is configured in the BWP-UplinkDedicated parameter of the Config information of PUSCH.

[0139] For example, if the network device configures ulpowerControl in BWP-UplinkDedicated containing PUCCH-Config, fields such as ul-FullPowerTransmissionPC3-r18, ul-FullPowerTransmissionPC2-r18, and ul-FullPowerTransmissionPC1dot5-r18 are no longer configured.

[0140] In some embodiments of the present disclosure, the network device sends second configuration information to the user equipment, where the second configuration information includes the corresponding codebook subset type of the user equipment in at least one full-power transmission mode. After receiving the second configuration information, the user equipment configures the corresponding codebook subset type according to the second configuration information.

[0141] The codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent.

[0142] For example, the network device supports the UE to select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent in the fullpower mode by adding the codebookSubsetwithfullpower-r18 field.

[0143] The network device supports the UE to select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent in the fullpowerMode1 mode by adding the codebookSubsetwithfullpowerMode1-r18 field.

[0144] The network device supports the UE to select its antenna coherence from fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent in the fullpowerMode1 mode by adding the codebookSubsetwithfullpowerMode2-r18 field.

[0145] For the above three fields, the network device can choose to configure one field, two fields, or three fields.

[0146] In the above embodiments, when the UE power level changes, the full-power transmission mode also changes. The network device realizes the change of the codebook subset mode of the UE by sending the second configuration information to the UE, which can reduce the problem of incorrect configuration of the TPMI table and improve the accuracy of network device scheduling and management.

[0147] In some embodiments, in combination with the existing TPMI table corresponding to the full-power mode, the optional items of antenna coherence can be further streamlined. That is, when the user equipment is in full-power transmission mode 0 or full-power transmission mode 2, the codebook subset types include one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent; and when the user equipment is in full-power transmission mode 1, the codebook subset types include one of partialAndNonCoherent and NonCoherent.

[0148] Compared with the previous embodiment, there are only two choices for antenna coherence in the fullpowerMode1 mode, namely partialAndNonCoherent and nonCoherent.

[0149] Figure 4 FIG. is a schematic structural diagram of some embodiments of a user equipment according to the present disclosure. The user equipment includes a receiving module 410 configured to receive first configuration information, where the first configuration information includes configuring at least one full-power transmission mode for the user equipment at at least one power level.

[0150] In some embodiments, the receiving module 410 receives the first configuration information sent by a network device such as a base station. The first configuration information is, for example, an RRC parameter, and the RRC parameter is configured in PUSCH-Config.

[0151] In some embodiments, the at least one power level includes at least one of PC3, PC2, and PC1.5.

[0152] In some embodiments, the at least one full-power transmission mode includes one or two of fullpower, fullpowerMode1, and fullpowerMode2.

[0153] In some embodiments, the user equipment further includes a configuration module 420 configured to configure at least one full-power transmission mode according to the first configuration information.

[0154] In the above embodiments, after receiving the first configuration information, the UE configures at least one full-power transmission mode according to the first configuration information, which can reduce the UE power back-off but the full-power transmission mode remains unchanged, thus causing an unreasonable scheduling problem.

[0155] In some embodiments, the receiving module 410 is further configured to receive indication information by the UE, where the indication information includes an indication of the full-power transmission mode selected by the user equipment.

[0156] For example, when the UE receives configuration information that configures one of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is determined by an indication sent by a network device such as a base station. The indication information is configured in the DCI.

[0157] For another example, when the UE receives configuration information that configures two of full-power transmission mode 0, full-power transmission mode 1, and full-power transmission mode 2 at at least one power level, which specific mode to select subsequently is determined by an indication sent by a network device such as a base station. The indication information is configured in the DCI.

[0158] In some embodiments, the UE can also select the full-power transmission mode to be used by itself, so that when the UE power back-off occurs, the full-power mode changes adaptively, which is convenient for the base station to perform reasonable scheduling.

[0159] In other embodiments of the present disclosure, the receiving module 410 is further configured to receive second configuration information, where the second configuration information includes the corresponding codebook subset type of the user equipment in at least one full-power transmission mode. The configuration module 420 is further configured to configure the corresponding codebook subset type according to the second configuration information.

[0160] For example, the codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent.

[0161] In some embodiments, in order to match the existing TPMI table corresponding to the full-power mode, when the user equipment is in full-power transmission mode 0 or full-power transmission mode 2, the codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent; and when the user equipment is in full-power transmission mode 1, the codebook subset type includes one of partialAndNonCoherent and NonCoherent.

[0162] In the above embodiments, when the UE power level changes, the full - power transmission mode also changes. Through the second configuration information, the change of the codebook subset mode is realized, which can reduce the misconfiguration problem of the TPMI table and improve the accuracy of network device scheduling and management.

[0163] Figure 5 The following is a schematic structural diagram of some embodiments of the network device of the present disclosure. The network device includes a sending module 510, configured to send first configuration information to a user equipment.

[0164] In some embodiments, the at least one power level includes at least one of power level 3, power level 2, and power level 1.5.

[0165] In some embodiments, the at least one full - power transmission mode includes one or two of full - power transmission mode 0, full - power transmission mode 1, and full - power transmission mode 2.

[0166] In some embodiments, the first configuration information includes at least one of the following: supporting configuring a UE with PC3 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring a UE with PC2 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring a UE with PC1.5 as one of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2.

[0167] In some embodiments, the first configuration information includes at least one of the following: supporting configuring a UE with PC3 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring a UE with PC2 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2; supporting configuring a UE with PC1.5 as any two of the three transmission modes of fullpower, fullpowerMode1, and fullpowerMode2.

[0168] In the above embodiments, the network device sends configuration information to the UE so that the UE configures at least one full-power transmission mode at at least one power level, which can reduce the unreasonable scheduling problem caused by the UE power back-off but the unchanged full-power transmission mode.

[0169] In some embodiments, the sending module 510 is further configured to send first configuration information to the user equipment without sending ulpowerControl to the user equipment. The ulpowerControl is configured in the BWP-UplinkDedicated parameter of the Config information of the PUSCH.

[0170] In some embodiments, the sending module 510 is further configured to send second configuration information to the user equipment, where the second configuration information includes the corresponding codebook subset type of the user equipment in at least one full-power transmission mode.

[0171] The codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent.

[0172] In some embodiments, in order to match the TPMI table corresponding to the existing full-power mode, when the user equipment is in full-power transmission mode 0 or full-power transmission mode 2, the codebook subset type includes one of fullyAndPartialAndNonCoherent, partialAndNonCoherent, and NonCoherent; and when the user equipment is in full-power transmission mode 1, the codebook subset type includes one of partialAndNonCoherent and NonCoherent.

[0173] In the above embodiments, when the UE power level changes and the full-power transmission mode also changes, the network device realizes the change of the UE codebook subset mode by sending the second configuration information, which can reduce the misconfiguration problem of the TPMI table and improve the accuracy of network device scheduling and management.
