Description

Technical Field

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

[0002] Due to the limitations of the codebook and PUSCH (Physical Uplink Shared Channel) power control in R15, full power transmission (e.g., 26 dBm) cannot be achieved in some cases, which affects the uplink coverage and rate. UL full power Tx (uplink full power transmission) was proposed in 3GPP (3rd Generation Partnership Project) R16 (Release 16), and different uplink full power transmission modes (UL FP Tx Mode) were designed for UEs (User Equipment) with PA (Power Amplifier) capabilities.

[0003] In the PUSCH transmission based on the codebook, the TPMI table can be used to indicate the coherence of the antenna (codebook subset type), the number of layers, and the transmission precoding matrix indicator (TPMI) under different antenna ports. The user equipment is configured according to the TPMI table in the subsequent uplink transmission. Summary of the Invention

[0004] The inventors found that: in some cases, the uplink full power transmission mode of the UE will change. However, after the uplink full power transmission mode of the UE changes, the original TPMI table is still used. The configuration information matching the current uplink full power transmission model may not be found in the original TPMI table, resulting in inaccurate precoding and problems in uplink transmission, and the communication quality deteriorates.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present disclosure and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0051] The present disclosure provides a configuration method, which will be described below in conjunction with Figures 1 to 3 for description.

[0052] Figure 1 is a flowchart of some embodiments of the configuration method of the present disclosure. As Figure 1 shown, the method of this embodiment includes: steps S102 to S104.

[0053] In step S102, the network device sends first configuration information to the user equipment.

[0054] In step S104, the user equipment receives the first configuration information sent by the network device.

[0055] The first configuration information includes at least one of a codebook subset type, layer information, and TPMI information corresponding to the current uplink full power transmission (UL Full Power Transmission) mode of the user equipment.

[0056] At least one of the codebook subset type, layer information, and TPMI information also corresponds to the number of antenna ports and the maximum transmission layer rank of the user equipment.

[0057] In some embodiments, the uplink full power transmission mode includes at least one of full power mode 0, full power mode 1, and full power mode 2. The codebook subset type is used to indicate the coherence of the antenna and includes at least one of fullyAndPartialAndNonCoherent, PartialAndNonCoherent, and nonCoherent.

[0058] In some embodiments, when the uplink full power transmission mode of the user equipment changes, the first configuration information is received.

[0059] For example, if the uplink full-power transmission mode of the user equipment changes, but there is no corresponding configuration information in the TPMI table, the network device sends the first configuration information. Correspondingly, the user equipment receives the first configuration information.

[0060] In some embodiments, before step S102, it further includes: the user equipment reports capability information, where the capability information includes combined information or bundled information of at least two of the capability information of the power level, the capability information of uplink full-power transmission, and the capability information of the codebook subset.

[0061] For example, when reporting the capabilities of the user equipment, at least two of the power level, full-power transmission mode, and codebook subset type (antenna coherence) of the user equipment are reported jointly. For example, the user equipment may report the corresponding full-power transmission mode and / or codebook subset type for each power level. For example, the user equipment reports the full-power transmission mode and / or codebook subset type under PC3 (power level 3).

[0062] In some embodiments, the first configuration information further includes combined information or bundled information of at least two of the configuration information of the power level, the configuration information of uplink full-power transmission, and the configuration information of the codebook subset.

[0063] In some embodiments, the first configuration information includes: RRC parameters and their corresponding values, where the RRC parameters are jointly represented by at least two of the identification information of the power level, the identification information of uplink full-power transmission, and the identification information of the codebook subset. For example, the identification information includes at least one of a name and an indicator. For example, the RRC parameter is represented as ul-FullPowerTransmissionPC3-r18, indicating the full-power transmission mode that can be configured for a user equipment with a power level of PC3.

[0064] For example, when configuring, at least two of the power level, uplink full-power transmission mode, and codebook subset type of the user equipment are configured jointly.

[0065] For example, it is configured as the corresponding uplink full-power transmission mode and / or codebook subset type for each power level. For example, it is configured as the uplink full-power transmission mode and / or codebook subset type under PC3.

[0066] In some embodiments, the first configuration information further includes: index information corresponding to each layer information and TPMI information.

[0067] For example, the index information is Bit field mapped to index.

[0068] In some embodiments, the codebook subset type, layer information, and TPMI information are the information missing from the configured TPMI table; or the codebook subset type, layer information, and TPMI information are located in a new TPMI table.

[0069] For example, the codebook subset type, layer information, and TPMI information are the information missing from the TPMI table, and at least one of the missing codebook subset type, layer information, and TPMI information is added to the TPMI table. For example, as shown in Table 1, for the precoding information and the number of layers when the antenna port is 4, if the transform precoder is disabled, the maximum transmission layer number (maxRank) is 2, and the uplink full-power transmission mode is fullpowermode1 (full-power mode 1), a column (the second column from the left) of configuration information (which may include layer information and / or TPMI information) with the codebook subset type of fullyAndPartialAndNonCoherent is added.

[0070]

[0071] Table 1

[0072] As shown in Table 1, a new column (the first column from the left) of information can also be added as the index (Bit field mapped to index) corresponding to each layer information and / or TPMI information.

[0073] For example, as shown in Table 2, for the precoding information and the number of layers when the antenna port is 4, if the transform precoder is disabled, the maximum transmission layer number (maxRank) is 2, the uplink full-power transmission mode is fullpowermode1 (full-power mode 1), and ul-FullPowerTransmissionPC3-r18 is configured, a new TPMI table is defined specifically for the configuration of the uplink full-power transmission mode modification scenario.

[0074]

[0075] Table 2

[0076] In some embodiments, the first configuration information includes a TPMI table, and the TPMI table includes layer information and TPMI information corresponding to one or more codebook subset types. The TPMI table also includes index information corresponding to each codebook subset type, each layer information, and TPMI information.

[0077] In some embodiments, the user equipment does not expect the codebook subset type to be configured as fullyAndPartialAndNonCoherent, or does not expect the codebook subset type to be configured as fullyAndPartialAndNonCoherent when the current uplink full-power transmission mode of the user equipment is full-power mode 1.

[0078] For example, when at least one of the following occurs: reporting of a power back-off value, reporting of a power increase value, power headroom exceeding a threshold, reporting of auxiliary information, the user equipment will modify the uplink full-power transmission mode. If the uplink full-power transmission mode is modified, the UE does not expect the codebook subset type to be configured as fullyAndPartialAndNonCoherent.

[0079] For example, if the uplink full-power transmission mode is modified, the UE does not expect the codebook subset type to be configured as fullyAndPartialAndNonCoherent when the uplink full-power transmission mode is modified to mode 1 (fullpowermode1).

[0080] In some embodiments, the user equipment ignores the layer information and TPMI information corresponding to the codebook subset type fullyAndPartialAndNonCoherent, and selects information from the layer information and TPMI information corresponding to the codebook subset type partialAndNonCoherent or NonCoherent for configuration; or ignores the layer information and TPMI information corresponding to the codebook subset type fullyAndPartialAndNonCoherent, and selects information from the configured TPMI table for configuration.

[0081] For example, if the uplink full-power transmission mode is modified, but the base station configures the codebook subset type as fullyAndPartialAndNonCoherent, the UE will ignore this configuration and select from the configuration information (layers and / or TPMI) of the codebook subset type partialAndNonCoherent or nonCoherent corresponding to the new (current) uplink full-power transmission mode.

[0082] For example, if the uplink full-power transmission mode is modified, but the base station configures the codebook subset type as fullyAndPartialAndNonCoherent, the UE will ignore this configuration. For example, continue to use the configuration information in the original TPMI table.

[0083] In some embodiments, when the current uplink full-power transmission mode of the user equipment is full-power mode 1, the user equipment ignores the layer information and TPMI information corresponding to the codebook subset type fullyAndPartialAndNonCoherent, and selects information from the layer information and TPMI information corresponding to the codebook subset type partialAndNonCoherent or NonCoherent for configuration; or ignores the layer information and TPMI information corresponding to the codebook subset type fullyAndPartialAndNonCoherent, and selects information from the configured TPMI table for configuration.

[0084] For example, if the uplink full-power transmission mode is modified to full-power mode 1, but the base station configures the codebook subset type as fullyAndPartialAndNonCoherent, the UE will ignore this configuration and select from the configuration information (layers and / or TPMI) of the codebook subset type partialAndNonCoherent or nonCoherent corresponding to the new uplink full-power transmission mode.

[0085] For example, if the uplink full-power transmission mode is modified to full-power mode 1, but the base station configures the codebook subset type as fullyAndPartialAndNonCoherent, the UE will ignore this configuration. For example, continue to use the configuration information in the original TPMI table.

[0086] In some embodiments, the configuration method further includes: the user equipment configures at least one of the codebook subset type, layer information, and TPMI information according to the first configuration information.

[0087] In the method of the above embodiments, the user equipment receives the first configuration information, and the first configuration information includes at least one of the codebook subset type, layer information, and TPMI information corresponding to the current uplink full-power transmission mode of the user equipment. According to the method of the above embodiments, after the uplink full-power transmission mode of the user equipment changes, at least one of the codebook subset type, layer information, and TPMI information corresponding to the current uplink full-power transmission mode can be determined, thereby improving the accuracy of the configuration information of the user equipment and enhancing the communication quality.

[0088] Next, in conjunction with Figure 2 Describe some other embodiments of the configuration method of the present disclosure.

[0089] Figure 2 It is a flowchart of some other embodiments of the configuration method of the present disclosure. As Figure 2As shown, the method of this embodiment includes steps S202 to S204.

[0090] In step S202, the network device sends second configuration information to the user equipment.

[0091] In step S204, the user equipment receives the second configuration information sent by the network device.

[0092] The second configuration information includes: configuration information of SRS (Sounding Reference Signal) resources corresponding to the current uplink full-power transmission mode of the user equipment. The second configuration information includes: configuration information of SRS resources. For example, the second configuration information includes configuration information of SRS resources.

[0093] In some embodiments, receiving the second configuration information includes at least one of the following: receiving the second configuration information when the uplink full-power transmission mode of the user equipment changes; receiving the second configuration information when the uplink full-power transmission mode of the user equipment does not correspond to the number of layers or ports of the user equipment; receiving the second configuration information when the user equipment sends layer-related auxiliary information to the network.

[0094] For example, if the uplink full-power transmission mode of the user equipment changes, it may mean that the SRS needs to be changed, and then the configuration information of the SRS corresponding to the current uplink full-power transmission mode is configured through the second configuration information.

[0095] In some embodiments, the situation where the uplink full-power transmission mode of the user equipment does not correspond to the number of layers or ports of the user equipment includes at least one of the following: the number of layers required by the uplink full-power transmission mode of the user equipment is not equal to the number of layers of the SRS resources in the second configuration information; the number of ports required by the uplink full-power transmission mode of the user equipment is not equal to the number of ports of the SRS resources in the second configuration information.

[0096] For example, the number of layers required by the uplink full-power transmission mode of the user equipment is greater than or less than the number of layers of the SRS resources in the second configuration information, and / or, the number of ports required by the uplink full-power transmission mode of the user equipment is greater than or less than the number of ports of the SRS resources in the second configuration information.

[0097] In some embodiments, the method of this embodiment further includes: after receiving the second configuration information, reporting layer-related auxiliary information; after the full-power transmission mode changes, reporting layer-related auxiliary information.

[0098] In some embodiments, the layer-related auxiliary information includes at least one of maximum layer information, current layer information, layer change information, and layer change amount information.

[0099] In some embodiments, the second configuration information includes: configuration information of a new SRS resource that is different from the configured SRS resource; or the second configuration information includes: information for modifying the configuration information of the configured SRS resource.

[0100] In some embodiments, the configuration information of the configured SRS resource includes the number of ports of the configured SRS resource.

[0101] For example, a new SRS resource can be configured. For example, the user equipment will be configured and / or instructed to have a new SRS resource, which may be simultaneous or after the indication of a change in the uplink full power transmission mode.

[0102] For example, the configuration information of the current SRS resource can be modified. For example, the SRS port number configuration can be modified, and the user equipment will receive the modified configuration information of the original SRS resource from the base station, which may be simultaneous or after the indication of a change in the uplink full power transmission mode.

[0103] For example, if there is no change in the SRS, the user equipment keeps the original SRS resource and configuration information unchanged.

[0104] In some embodiments, the configuration method further includes: the user equipment configures the SRS resource according to the second configuration information.

[0105] In the method of the above embodiments, the user equipment receives the second configuration information, and the second configuration information includes the configuration information of the SRS resource corresponding to the current uplink full power transmission mode of the user equipment. According to the method of the above embodiments, after the uplink full power transmission mode of the user equipment changes, the SRS resource corresponding to the current uplink full power transmission mode can be determined, avoiding the situation where the SRS resource does not match the current uplink full power model, thereby improving the accuracy of the configuration information of the user equipment and enhancing the communication quality.

[0106] The following combines Figure 3 to describe some other embodiments of the configuration method of the present disclosure.

[0107] Figure 3 is a flowchart of some other embodiments of the configuration method of the present disclosure. As Figure 3 shown, the method of this embodiment includes: steps S302 to S304.

[0108] In step S302, the network device sends the third configuration information to the user equipment.

[0109] In step S304, the user equipment receives the third configuration information sent by the network device.

[0110] In some embodiments, the third configuration information includes configuration information of a power scaling factor of a PUSCH (Physical Uplink Shared Channel) corresponding to the current uplink full-power transmission mode of the user equipment. The third configuration information includes the configuration information of the power scaling factor of the PUSCH.

[0111] In some embodiments, receiving the third configuration information includes receiving the third configuration information when at least one of the uplink full-power transmission mode of the user equipment, the configuration of the SRS resource, the configuration of the codebook subset, and the configuration of the TPMI group changes.

[0112] For example, if the uplink full-power transmission mode of the user equipment changes, the power parameter (e.g., the power scaling factor s) needs to be changed correspondingly.

[0113] In some embodiments, when the uplink full-power transmission mode of the user equipment changes, the value of the power scaling factor is 1.

[0114] In some embodiments, the change of the uplink full-power transmission mode of the user equipment includes one of the following: the uplink full-power transmission mode changes from full power mode 1 to full power mode 0; the uplink full-power transmission mode changes from full power mode 1 to full power mode 2; the uplink full-power transmission mode changes from full power mode 2 to full power mode 1; the uplink full-power transmission mode changes from full power mode 0 to full power mode 1.

[0115] For example, the value of the power scaling factor s will be adjusted according to the modification of the uplink full-power transmission mode. For example, if the uplink full-power transmission mode changes from full power mode 1 to full power mode 0, the value of s becomes 1.

[0116] For example, the value of the power scaling factor s will be adjusted according to the modification of the uplink full-power transmission mode and the modification of the SRS resource. For example, if the uplink full-power transmission mode changes to full power mode 1, the value of the power scaling factor s is determined and adjusted according to the ratio of the number of antenna ports with non-zero PUSCH transmission power to the maximum number of ports supported by the user equipment in the corresponding SRS resource.

[0117] For example, the value of the power scaling factor s will be adjusted according to the modification of the uplink full-power transmission mode, the modification of the SRS resource, and / or the configuration information of the codebook subset of the user equipment. For example, if the user equipment reports the configuration information of 1 TPMI group supporting FullPwrMode2 (full-power mode 2) through ul-FullPwrMode2-TPMIGroup-r16 according to its own capabilities, then if the actual PUSCH uses this configuration information, s = 1; otherwise, s is the ratio of the number of antenna ports corresponding to the non-zero PUSCH transmission power to the number of ports actually configured by the user equipment in this SRS resource.

[0118] In some embodiments, receiving the third configuration information includes at least one of the following: receiving the third configuration information when the full-power transmission mode of the user equipment does not correspond to the number of layers or ports of the user equipment; receiving the third configuration information when the user equipment sends layer-related auxiliary information to the network.

[0119] In some embodiments, the situation where the uplink full-power transmission mode of the user equipment does not correspond to the number of layers or ports of the user equipment includes at least one of the following: the number of layers required by the uplink full-power transmission mode of the user equipment is not equal to the number of layers of the SRS resource in the second configuration information; the number of ports required by the uplink full-power transmission mode of the user equipment is not equal to the number of ports of the SRS resource in the second configuration information.

[0120] For example, the number of layers required by the uplink full-power transmission mode of the user equipment is greater than or less than the number of layers of the SRS resource in the second configuration information, and / or the number of ports required by the uplink full-power transmission mode of the user equipment is greater than or less than the number of ports of the SRS resource in the second configuration information.
