[0055] The power reporting method and power determination method provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0056] As shown in FIG2 , an embodiment of the present application provides a power reporting method, the method comprising:

[0057] Step 201: The terminal reports information of an available uplink transmission link on at least one frequency band;

[0058] The information of the uplink transmission link includes: power information of the uplink transmission link; the power information includes: maximum transmission power and / or power level.

[0059] The embodiment of the present application defines that each uplink transmission link has its own power class (Power Class) or maximum transmission power. The terminal reports the number of uplink transmission links available on at least one frequency band and the maximum transmission power (or power class) of each uplink transmission link, indicating the maximum transmission power information available in various situations.

[0060] For example, in a single-band operating scenario, in the case of multi-antenna transmission, the terminal reports power information of multiple uplink transmission links available on the frequency band, thereby indicating the maximum transmission power available on the frequency band.

[0061] Optionally, the information of the uplink transmission link further includes: the number of the uplink transmission links.

[0062] In one implementation, the terminal explicitly indicates the number of uplink transmission links in the uplink transmission link information; in another implementation, the terminal implicitly indicates the number of uplink transmission links by the number of uplink transmission link power information carried in the uplink transmission link information.

[0063] Specific scenarios include, but are not limited to, scenarios of working only in a single frequency band and scenarios of working in carrier aggregation (CA).

[0064] In an optional implementation, when the terminal reports information about an available uplink transmission link on a frequency band, the frequency band is a frequency band used by the terminal in single-band transmission; or, the frequency band is a frequency band in carrier aggregation CA.

[0065] In another optional implementation, when the terminal reports information about available uplink transmission links on multiple frequency bands, the multiple frequency bands are multiple frequency bands in CA.

[0066] In at least one embodiment of the present application, the maximum transmit power of the terminal on a frequency band is: the sum of the maximum transmit powers of all uplink transmit links reported on the frequency band;

[0067] or,

[0068] The maximum transmit power of the terminal in a frequency band is: the sum of the maximum transmit powers corresponding to the power levels of all uplink transmit links reported in the frequency band.

[0069] In the case of single-band operation, the terminal transmits only on one frequency band. Whether sending data or uplink multiple input multiple output (UL-MIMO), the default maximum capability is to use all links on this frequency band. Therefore, this application defines the following capability of cumulatively calculating the maximum transmit power. When the terminal reports that it supports this capability, its maximum transmit power on a certain frequency band is the sum of the maximum transmit powers of all uplink transmit links reported on this frequency band.

[0070] It should be noted that the power level of the uplink transmission link in the embodiment of the present application can be referred to as P PowerClass,chainThe value range can follow the power class definition and power mapping of the frequency band in the related art, or it can use new definitions and power values. For example, the power class 3 / power class 2 in the related art can still be used, and power class 3 / power class 2 corresponds to a maximum output power of 23dBm and 26dBm respectively; for another example, power class 4 / power class 5 can be newly defined, and power class 4 / power class 5 corresponds to a maximum output power of 28dBm and 30dBm respectively. These are not listed here one by one.

[0071] As an optional embodiment, when the one frequency band is a frequency band used by the terminal in single-band transmission,

[0072] The upper limit of the configured maximum transmit power for a single band is the minimum of the maximum transmit power allowed by the network configuration and the maximum transmit power limited by the terminal power class.

[0073] The maximum transmit power limited by the terminal power level is the sum of the linear values ​​of the power level of each uplink transmit link in the frequency band.

[0074] For example, the upper limit of the maximum transmit power configured in a single frequency band is expressed by the first formula, which is:

[0075] P CMAX_H,f,c =MIN{P EMAX,c , 10log 10 ∑P PowerClass,chain};

[0076] Among them, P CMAX_H,f,c Configure the upper limit of the maximum transmit power for a single frequency band; P EMAX,c Configure the maximum transmit power allowed for the network; P PowerClass,chain is the linear value of the power level of a link in this frequency band, 10log 10 ∑P PowerClass,chain This sum represents the sum of the powers corresponding to the power levels of each uplink transmission link.

[0077] The above process can be directly reflected in the power class of a frequency band. In other words, the power class of a frequency band can be directly defined as the sum of the power classes of all transmit links, which serves as the definition of the power class of the frequency band. In other words, there is no need to set the corresponding numerical values ​​of the power class at the frequency band level. All power classes are defined only at the link level.

[0078] For example, if a terminal supports two uplink transmission links on band n78, the terminal can choose to report the maximum transmission power or power class corresponding to each of the two uplink transmission links. For example, the two links support 23dBm and 26dBm maximum transmission powers, corresponding to power classes 3 and 2. When the terminal has the ability to cumulatively calculate the maximum transmission power under a specific single frequency band, the upper limit of the maximum transmission power on the current frequency band can be calculated according to the formula 10log 10 ∑pPowerClass,chain takes the sum of the power levels of link 1 and link 2 (23 dBm + 26 dBm). De-linearize each value and sum it to approximately 27.8 dBm. This is used as the total power level limit for the current frequency band and is used to define the power cap.

[0079] For another example, when the terminal supports three transmission links on the uplink of n78, the terminal can report the maximum transmission power or power level corresponding to each of the three uplink transmission links. For example, these three links support maximum transmission powers of 23dBm, 23dBm, and 23dBm respectively, and the corresponding power levels are all power class 3. When the terminal has the ability to cumulatively calculate the maximum transmission power under a specific single frequency band, the upper limit of the maximum transmission power on the current frequency band can be calculated according to the formula 10log 10 ∑pPowerClass,chain takes the sum of the power levels of the three links (23dBm + 23dBm + 23dBm), delinearizes each of them, and then takes the sum, which is approximately 27.8dBm. This is used as the total power level limit for the current frequency band and is included in the definition of the power cap.

[0080] When there are more available uplink transmission links on a frequency band, such as 4 transmission links or 5 transmission links, the above example can also be referred to and will not be repeated here.

[0081] In the above example, the total power level of the current band can be defined as a separate power level according to the strategy in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0082] When the terminal operates in carrier aggregation (CA), the uplink transmission link conditions on each operating frequency band may be different from those when only a single frequency band is operating. Therefore, the reporting conditions can be independent of the single-band operation condition. In this case, per-band per-band combination reporting is also required under the current combination. The concept definition of the power class of each uplink transmission link and the method of obtaining the power class are consistent with the single-carrier case.

[0083] For example, a terminal can support two uplink links in the n8 band, with maximum transmit powers of 23dBm and 26dBm, corresponding to power classes 3 and 2, respectively. In the CA combination CA_n8-n78, consisting of n8 and n78, if the terminal can only support two simultaneous uplink transmit links (across all bands) and requires at least one link on n78, n8 can only support one uplink transmit link. Depending on whether it uses a 23dBm or 26dBm link, the terminal can report its maximum transmit power of 23dBm or 26dBm for n8 in the CA combination CA_n8-n78, corresponding to power class 3 or 2. The maximum transmit power cap for the corresponding carrier in n8 is calculated using 10log10∑Ppowerclass,chain. Here, only one value remains, 23dBm or 26dBm. This result serves as the total power limit for the current band and is used in the power cap definition.

[0084] Similarly, in the above example, the total power level of the current band can have a separate power level according to the strategy definition in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0085] In the above example, if the terminal can support a maximum of three uplink transmission links, the terminal can also report support for two transmission links on n8, and the power calculation on n8 can be the same as that on a single frequency band.

[0086] As another optional embodiment, the total maximum transmit power of the terminal on multiple frequency bands is: the sum of the maximum transmit powers of all uplink transmit links reported on the multiple frequency bands;

[0087] or,

[0088] The total maximum transmit power of the terminal in multiple frequency bands is: the sum of the maximum transmit powers corresponding to the power levels of all uplink transmit links reported in the multiple frequency bands.

[0089] When the terminal transmits on multiple carriers or multiple frequency bands, the method of extending the maximum transmit power of a single frequency band as described above can also be used to extend the maximum transmit power on each frequency band, thereby also extending the total maximum transmit power of the terminal on multiple carriers or multiple frequency bands.

[0090] For carrier aggregation (CA), the number of supported links and the corresponding link power level can be reported on each frequency band to obtain the number of uplink transmission links on each frequency band and the power level of each link. The total CA transmission power can be obtained by taking the sum of the power levels of all links.

[0091] In one implementation, the upper limit of the configured maximum transmit power for CA is the minimum of the sum of the linear values ​​of the maximum transmit power allowed by the network configuration, the maximum transmit power allowed by the network configuration for CA, and the maximum transmit power limited by the terminal power class.

[0092] The maximum transmit power limited by the terminal class is the linear sum of the power levels of all uplink transmit links on each frequency band of CA.

[0093] For example, the upper limit of the maximum transmit power configured by CA is expressed by the second formula, which is:

[0094] P CMAX_H =MIN{10log 10 ∑p EMAX,c , P EMAX,CA , 10log 10 ∑pPowerClass,chain}

[0095] Among them, P CMAX_H Configure the upper limit of the maximum transmit power for CA; 10log 10 ∑p EMAX,c The sum of the linear values ​​of the maximum transmit power allowed by the network configuration; P EMAX,CA The maximum CA transmission power allowed for the network configuration; pPowerClass,chain is the linear value of the power level of all links on each frequency band transmitted by CA; the sum of this represents the sum of the individual power levels of each link.

[0096] The above process can also be directly reflected in the definition of the overall power class of a frequency band combination. In other words, the total power class of a frequency band combination can be directly defined as the sum of the power levels of the transmit links on all the above frequency bands, which serves as the power class definition for the frequency band combination. In other words, instead of separately defining the power class values ​​corresponding to the frequency band combination level, all power classes are defined solely at the link level.

[0097] For example, a terminal operating in CA_n8-n78 can have up to three uplink transmit links. The terminal reports that under the current CA combination, n78 supports two uplink transmit links. These two links support maximum transmit powers of 23dBm and 26dBm, corresponding to link power classes 3 and 3, respectively. On n8, only one uplink transmit link is supported, with a transmit power of 23dBm corresponding to link power class 3. Therefore, the total maximum uplink transmit power can be the sum of the power of all three links. This is calculated using the formula 10log10∑pPowerClass,chain: 23dBm + 26dBm + 23dBm, resulting in a total of 29dBm. This serves as the total power limit for the current frequency band and is used in the power cap definition.

[0098] In the above example, the total power level of the current frequency band combination can have a separate power level according to the strategy definition in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0099] In the embodiment of the present application, when transmitting multiple links in a single frequency band, the physical layer can introduce a codebook for weighting each link. The codebook technology can implement beamforming, introduce directionality to the transmitted signal, and improve the received signal. The current default assumption is that the maximum transmit power of these links is equal, or the power is balanced. With the introduction of link-level power levels, a power imbalance scenario is introduced; at this time, the physical layer codebook may need to be adjusted in a targeted manner. The method provided in the embodiment of the present application also includes:

[0100] The terminal determines first indication information for indicating whether power of multiple uplink transmission links on a single frequency band is balanced; the first indication information is used to assist in selecting a codebook combination for the uplink transmission link.

[0101] Furthermore, the method further comprises:

[0102] The terminal reports the first indication information and selects a codebook for an uplink transmit link according to the first indication information;

[0103] or,

[0104] The terminal reports the first indication information, and the network side device selects a codebook for the uplink transmit link according to the first indication information.

[0105] In other words, depending on whether the maximum transmit powers of multiple links on a band of the terminal are consistent (consistent is considered balanced, inconsistent is considered unbalanced), the terminal or the network side selects different codebooks suitable for power balance or imbalance respectively.

[0106] In at least one embodiment of the present application, the terminal reports information of an available uplink transmission link on at least one frequency band, including:

[0107] The terminal reports information of an available uplink transmit link on at least one frequency band according to a first granularity; wherein the first granularity includes at least one of the following: per carrier, per UE, per band, per-band combination, per band per band combination, and per feature set.

[0108] In summary, the embodiments of the present application provide a granularity of power level or maximum transmit power for each transmit link, thereby expanding the definition of single-band uplink transmit power, improving uplink utilization of multiple transmit terminals in a single-band case, and improving uplink coverage.

[0109] As shown in FIG3 , an embodiment of the present application further provides a power determination method, the method comprising:

[0110] Step 301: A network-side device receives information about an available uplink transmission link on at least one frequency band reported by a terminal; wherein the uplink transmission link information includes power information of the uplink transmission link; and the power information includes maximum transmission power and / or power level.

[0111] Step 302: The network-side device determines the maximum transmit power of the terminal in at least one frequency band based on the uplink transmit link information.

[0112] The embodiment of the present application defines that each uplink transmission link has its own power class (Power Class) or maximum transmission power. The terminal reports the number of uplink transmission links available on at least one frequency band and the maximum transmission power (or power class) of each uplink transmission link, indicating the maximum transmission power information available in various situations.

[0113] Specific scenarios include but are not limited to scenarios of working only in a single frequency band and scenarios of working in carrier aggregation CA.

[0114] Optionally, the information of the uplink transmission link further includes: the number of the uplink transmission links.

[0115] In one implementation, the terminal explicitly indicates the number of uplink transmission links in the uplink transmission link information; in another implementation, the terminal implicitly indicates the number of uplink transmission links by the number of uplink transmission link power information carried in the uplink transmission link information.

[0116] In an optional implementation, when the terminal reports information about an available uplink transmission link on a frequency band, the frequency band is a frequency band used by the terminal in single-band transmission; or, the frequency band is a frequency band in carrier aggregation CA.

[0117] In another optional implementation, when the terminal reports information about available uplink transmission links on multiple frequency bands, the multiple frequency bands are multiple frequency bands in CA.

[0118] In at least one embodiment of the present application, the maximum transmit power of the terminal on a frequency band is: the sum of the maximum transmit powers of all uplink transmit links reported on the frequency band;

[0119] or,

[0120] The maximum transmit power of the terminal in a frequency band is: the sum of the maximum transmit powers corresponding to the power levels of all uplink transmit links reported in the frequency band.

[0121] In the case of single-band operation, the terminal transmits only on one frequency band. Whether sending data or uplink multiple-input multiple-output (UL-MIMO), the default maximum capability is to use all links on this frequency band. Therefore, this application defines the following capability of cumulatively calculating the maximum transmit power. When the terminal reports that it supports this capability, its maximum transmit power on a certain frequency band is the sum of the maximum transmit powers of all uplink transmit links reported on this frequency band.

[0122] It should be noted that the power level of the uplink transmission link in the embodiment of the present application can be referred to as P PowerClass,chainThe value range can follow the power class definition and power mapping of the frequency band in the related art, or it can use new definitions and power values. For example, the power class 3 / power class 2 in the related art can still be used, and power class 3 / power class 2 corresponds to a maximum output power of 23dBm and 26dBm respectively; for another example, power class 4 / power class 5 can be newly defined, and power class 4 / power class 5 corresponds to a maximum output power of 28dBm and 30dBm respectively. These are not listed here one by one.

[0123] As an optional embodiment, when the one frequency band is a frequency band used by the terminal in single-band transmission,

[0124] The upper limit of the maximum transmit power for a single-band configuration is the minimum of the maximum transmit power allowed by the network configuration and the maximum transmit power limited by the terminal power level.

[0125] The maximum transmit power limited by the terminal power level is the sum of the linear values ​​of the power level of each uplink transmit link in the frequency band.

[0126] For example, the upper limit of the maximum transmit power configured in a single frequency band is expressed by the first formula, which is:

[0127] P CMAX_H,f,c =MIN{P EMAX,c , 10log 10 ∑P PowerClass,chain};

[0128] Among them, P CMAX_H,f,c Configure the upper limit of the maximum transmit power for a single frequency band; P EMAX,c Configure the maximum transmit power allowed for the network; P PowerClass,chain is the linear value of the power level of a link in this frequency band, 10log 10 ∑P PowerClass,chain This sum represents the sum of the powers corresponding to the power levels of each uplink transmission link.

[0129] The above process can be directly reflected in the power class of a frequency band. In other words, the power class of a frequency band can be directly defined as the sum of the power classes of all transmit links, which serves as the definition of the power class of the frequency band. In other words, there is no need to set the corresponding numerical values ​​of the power class at the frequency band level. All power classes are defined only at the link level.

[0130] For example, if a terminal supports two uplink transmission links on band n78, the terminal can choose to report the maximum transmission power or power class corresponding to each of the two uplink transmission links. For example, the two links support 23dBm and 26dBm maximum transmission powers, corresponding to power classes 3 and 2. When the terminal has the ability to cumulatively calculate the maximum transmission power under a specific single frequency band, the upper limit of the maximum transmission power on the current frequency band can be calculated according to the formula 10log 10 ∑pPowerClass,chain takes the sum of the power levels of link 1 and link 2 (23 dBm + 26 dBm). De-linearize each value and sum it to approximately 27.8 dBm. This is used as the total power level limit for the current frequency band and is used to define the power cap.

[0131] For another example, when the terminal supports three transmission links on the uplink of n78, the terminal can report the maximum transmission power or power level corresponding to each of the three uplink transmission links. For example, these three links support maximum transmission powers of 23dBm, 23dBm, and 23dBm respectively, and the corresponding power levels are all power class 3. When the terminal has the ability to cumulatively calculate the maximum transmission power under a specific single frequency band, the upper limit of the maximum transmission power on the current frequency band can be calculated according to the formula 10log 10 ∑pPowerClass,chain takes the sum of the power levels of the three links (23dBm + 23dBm + 23dBm), delinearizes each of them, and then takes the sum, which is approximately 27.8dBm. This is used as the total power level limit for the current frequency band and is included in the definition of the power cap.

[0132] When there are more available uplink transmission links on a frequency band, such as 4 transmission links or 5 transmission links, the above example can also be referred to and will not be repeated here.

[0133] In the above example, the total power level of the current band can be defined as a separate power level according to the strategy in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0134] When the terminal operates in carrier aggregation (CA), the uplink transmission link conditions on each operating frequency band may be different from those when only a single frequency band is operating. Therefore, the reporting conditions can be independent of the single-band operation condition. In this case, per-band per-band combination reporting is also required under the current combination. The concept definition of the power class of each uplink transmission link and the method of obtaining the power class are consistent with the single-carrier case.

[0135] For example, a terminal can support two uplink links in the n8 band, with maximum transmit powers of 23dBm and 26dBm, corresponding to power classes 3 and 2, respectively. In the CA combination CA_n8-n78, consisting of n8 and n78, if the terminal can only support two simultaneous uplink transmit links (across all bands) and requires at least one link on n78, n8 can only support one uplink transmit link. Depending on whether it uses a 23dBm or 26dBm link, the terminal can report its maximum transmit power of 23dBm or 26dBm for n8 in the CA combination CA_n8-n78, corresponding to power class 3 or 2. The maximum transmit power cap for the corresponding carrier in n8 is calculated using 10log10∑Ppowerclass,chain. Here, only one value remains, 23dBm or 26dBm. This result serves as the total power limit for the current band and is used in the power cap definition.

[0136] Similarly, in the above example, the total power level of the current band can have a separate power level according to the strategy definition in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0137] In the above example, if the terminal can support a maximum of three uplink transmission links, the terminal can also report support for two transmission links on n8, and the power calculation on n8 can be the same as that on a single frequency band.

[0138] As another optional embodiment, the total maximum transmit power of the terminal on multiple frequency bands is: the sum of the maximum transmit powers of all uplink transmit links reported on the multiple frequency bands;

[0139] or,

[0140] The total maximum transmit power of the terminal in multiple frequency bands is: the sum of the maximum transmit powers corresponding to the power levels of all uplink transmit links reported in the multiple frequency bands.

[0141] When the terminal transmits on multiple carriers or multiple frequency bands, the method of extending the maximum transmit power of a single frequency band as described above can also be used to extend the maximum transmit power on each frequency band, thereby also extending the total maximum transmit power of the terminal on multiple carriers or multiple frequency bands.

[0142] For carrier aggregation (CA), the number of supported links and the corresponding link power level can be reported on each frequency band to obtain the number of uplink transmission links on each frequency band and the power level of each link. The total CA transmission power can be obtained by taking the sum of the power levels of all links.

[0143] In one implementation, the upper limit of the maximum transmit power configured for CA is the minimum of the sum of the linear value of the maximum transmit power allowed by the network configuration, the maximum transmit power allowed by the network configuration for CA, and the maximum transmit power limited by the terminal power class.

[0144] The maximum transmit power limited by the terminal class is the linear sum of the power levels of all uplink transmit links on each frequency band of CA.

[0145] For example, the upper limit of the maximum transmit power configured by CA is expressed by the second formula, which is:

[0146] P CMAX_H =MIN{10log 10 ∑p EMAX,c , P EMAX,CA , 10log 10 ∑pPowerClass,chain}

[0147] Among them, P CMAX_H Configure the upper limit of the maximum transmit power for CA; 10log 10 ∑p EMAX,c The sum of the linear values ​​of the maximum transmit power allowed by the network configuration; P EMAX,CA The maximum CA transmission power allowed for the network configuration; pPowerClass,chain is the linear value of the power level of all links on each frequency band transmitted by CA; the sum of this represents the sum of the individual power levels of each link.

[0148] The above process can also be directly reflected in the definition of the overall power class of a frequency band combination. In other words, the total power class of a frequency band combination can be directly defined as the sum of the power levels of the transmit links on all the above frequency bands, which serves as the power class definition for the frequency band combination. In other words, instead of separately defining the power class values ​​corresponding to the frequency band combination level, all power classes are defined solely at the link level.

[0149] For example, a terminal operating in CA_n8-n78 can have up to three uplink transmit links. The terminal reports that under the current CA combination, n78 supports two uplink transmit links. These two links support maximum transmit powers of 23dBm and 26dBm, corresponding to link power classes 3 and 3, respectively. On n8, only one uplink transmit link is supported, with a transmit power of 23dBm corresponding to link power class 3. Therefore, the total maximum uplink transmit power can be the sum of the power of all three links. This is calculated using the formula 10log10∑pPowerClass,chain: 23dBm + 26dBm + 23dBm, resulting in a total of 29dBm. This serves as the total power limit for the current frequency band and is used in the power cap definition.

[0150] In the above example, the total power level of the current frequency band combination can have a separate power level according to the strategy definition in the relevant technology, or the power level of the frequency band can be directly defined as this sum as a basic definition; no specific limitation is made here.

[0151] In the embodiment of the present application, when transmitting multiple links in a single frequency band, the physical layer can introduce a codebook for weighting each link. The codebook technology can implement beamforming, introduce directionality to the transmitted signal, and improve the received signal. The current default assumption is that the maximum transmit power of these links is equal, or the power is balanced. With the introduction of link-level power levels, a power imbalance scenario is introduced; at this time, the physical layer codebook may need to be adjusted in a targeted manner. The method provided in the embodiment of the present application also includes:

[0152] receiving first indication information reported by the terminal, where the first indication information is used to indicate whether power of multiple uplink transmit links on a single frequency band is balanced;

[0153] A codebook is selected for an uplink transmit link according to the first indication information.

[0154] In other words, depending on whether the maximum transmit powers of multiple links on a band of the terminal are consistent (consistent is considered balanced, inconsistent is considered unbalanced), the terminal or the network side selects different codebooks suitable for power balance or imbalance respectively.

[0155] In at least one embodiment of the present application, the network-side device receives information about an available uplink transmission link on at least one frequency band reported by the terminal, including:

[0156] The network-side device receives information on an available uplink transmit link on at least one frequency band reported by the terminal according to a first granularity; wherein the first granularity includes at least one of the following: per carrier, per UE, per band, per-band combination, per band per band combination, and per feature set.

[0157] In summary, the embodiments of the present application provide a granularity of power level or maximum transmit power for each transmit link, thereby expanding the definition of single-band uplink transmit power, improving uplink utilization of multiple transmit terminals in a single-band case, and improving uplink coverage.

[0158] As shown in FIG4 , an embodiment of the present application further provides a power determination method, the method comprising:

[0159] Step 401: The terminal obtains a pre-agreed terminal capability parameter, where the terminal capability parameter is used to indicate a maximum power value of an uplink transmission of the terminal.

[0160] An embodiment of the present application defines a terminal capability parameter for indicating the maximum power value of the terminal's uplink transmission; it can also be understood as indicating that the power level of the terminal in a certain frequency band can be replaced by a power value that does not belong to any power level, that is, the transmission power in this frequency band is no longer limited by the power level limit in the relevant technology.

[0161] Optionally, the method further includes:

[0162] The terminal reports the terminal capability parameters to the network side device.

[0163] In other words, the power value used to replace the power level can be agreed in advance in the specification or reported separately. Alternatively, the power value used to replace the power level can be a single value or a list, and one of the values ​​in the list can be selected by the instruction.

[0164] Optionally, the terminal capability parameter includes: a maximum power value list, the maximum power value list including multiple maximum power values;

[0165] The method further comprises:

[0166] The terminal sends second indication information to the network side device, where the second indication information is used for a maximum power value among the multiple maximum power values.

[0167] For single-antenna terminals, if the maximum transmit power capability of a link is between two power levels in related technologies, for example, 24.5 dBm, between PC2 (26 dBm) and PC3 (23 dBm), a direct indication is not currently available.

[0168] For example, a terminal has two transmit links on a frequency band, with maximum transmit powers of 26dBm and 23dBm, respectively. The total power is approximately 27.8dBm. This maximum power cannot be indicated by the current power level.

[0169] Given the terminal capability parameters above, a predefined power level, such as 27.8dBm, can be predefined. When the terminal reports a specific capability, this power level can be used to replace the maximum transmit power, rather than the current power class. The maximum transmit power for this frequency band may not be consistent with the power class specified in related technologies.

[0170] In one implementation, the upper limit of the maximum transmit power configured in a single frequency band is: the minimum value of the maximum transmit power allowed by the network configuration and the maximum transmit power limited by the terminal power level; wherein the maximum transmit power limited by the terminal power level is replaced by a pre-agreed value such as 27.8dBm; or replaced by an item in Table 1 agreed in advance according to the reported signaling; or replaced by a directly reported value.

[0172] As an optional embodiment, the terminal reporting the terminal capability parameter to the network side device includes:

[0173] The terminal reports the terminal capability parameters to the network side device according to the second granularity, wherein the second granularity includes at least one of the following: per carrier, per UE, per Band, per-band combination, per band per band combination, and per feature set.

[0174] In summary, the embodiment of the present application provides a terminal capability parameter for indicating that the power level of the terminal in a certain frequency band is replaced by a power value that does not belong to any power level, thereby expanding the definition of single-band uplink transmission power, improving the uplink utilization of multi-transmitting terminals in a single-band case, and improving uplink coverage.

[0175] As shown in FIG5 , an embodiment of the present application further provides a power determination method, the method comprising:

[0176] In step 501, the network side device obtains a pre-agreed terminal capability parameter, which is used to indicate the maximum power value of the terminal uplink transmission; or, the network side device receives a terminal capability parameter sent by the terminal, which is used to indicate the maximum power value of the terminal uplink transmission.

[0177] An embodiment of the present application defines a terminal capability parameter for indicating the maximum power value of the terminal's uplink transmission; it can also be understood as indicating that the power level of the terminal in a certain frequency band can be replaced by a power value that does not belong to any power level, that is, the transmission power in this frequency band is no longer limited by the power level limit in the relevant technology.

[0178] The power value used to replace the power level can be agreed in advance in the specification or reported separately. Alternatively, the power value used to replace the power level can be a single value or a list, and one of the values ​​in the list can be selected by the indication.

[0179] Optionally, the terminal capability parameter includes: a maximum power value list, the maximum power value list including multiple maximum power values;

[0180] The method further comprises:

[0181] The network side device receives second indication information sent by the terminal, where the second indication information is used for a maximum power value among the multiple maximum power values;

[0182] Determine the maximum power value of the terminal uplink transmission according to the second indication information and the maximum power value list.

[0183] For single-antenna terminals, if the maximum transmit power capability of a link is between two power levels in related technologies, for example, 24.5 dBm, between PC2 (26 dBm) and PC3 (23 dBm), a direct indication is not currently available.

[0184] For example, a terminal has two transmit links on a frequency band, with maximum transmit powers of 26dBm and 23dBm, respectively. The total power is approximately 27.8dBm. This maximum power cannot be indicated by the current power level.

[0185] Given the terminal capability parameters above, a predefined power level, such as 27.8dBm, can be predefined. When the terminal reports a specific capability, this power level can be used to replace the maximum transmit power, rather than the current power class. The maximum transmit power for this frequency band may not be consistent with the power class specified in related technologies.

[0186] In one implementation, the upper limit of the maximum transmit power configured in a single frequency band is: the minimum value of the maximum transmit power allowed by the network configuration and the maximum transmit power limited by the terminal power level; wherein the maximum transmit power limited by the terminal power level is replaced by a pre-agreed value such as 27.8dBm; or replaced by an item in a table agreed in advance according to the reported signaling; or replaced by a directly reported value.

[0187] As an optional embodiment, the network-side device receives the terminal capability parameter sent by the terminal, including:

[0188] The network side device receives the terminal capability parameter sent by the terminal according to the second granularity, wherein the second granularity includes at least one of the following: per carrier, per UE, per Band, per-band combination, per band per band combination, and per feature set.

[0189] In summary, the embodiment of the present application provides a terminal capability parameter for indicating that the power level of the terminal in a certain frequency band is replaced by a power value that does not belong to any power level, thereby expanding the definition of single-band uplink transmission power, improving the uplink utilization of multi-transmitting terminals in a single-band case, and improving uplink coverage.
