[0002] With the continuous development of mobile communication technology, the next generation of mobile communication technology may widely use high frequency bands such as 26GHz, 37GHz, 69GHz and even above 100GHz, and jointly deploy with the original frequency bands. Therefore, the spectrum in the next generation of mobile communication technology has the characteristics of multiple frequency points and large span, and the bandwidth of medium and low frequencies is small and the bandwidth of high frequencies is large, and the efficiency of spectrum utilization needs to be improved urgently.

[0052] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0053] Figure 1 FIG. 2 shows an exemplary application system architecture diagram to which the uplink power control method in the embodiment of the present disclosure can be applied. Figure 1 As shown, the system architecture may include a target terminal 101 , a network 102 and a network-side device 103 .

[0054] The target terminal 101 may obtain the terminal capability parameters of the target terminal 101 .

[0055] Then, if the terminal capability parameter indicates that the target terminal 101 supports the flexible carrier combination function, and the target terminal 101 does not support a downlink carrier with the same frequency band as the uplink, the target terminal 101 can determine the downlink path loss value accessed by the target terminal 101 and the path loss difference between the uplink and downlink. The target terminal 101 can request the downlink path loss value from the network side device 103.

[0056] Finally, the target terminal 101 may determine the uplink power of the target terminal 101 according to the downlink path loss value and the path loss difference.

[0057] The network 102 is a medium for providing a communication link between the target terminal 101 and the network-side device 103, and may be a wired network or a wireless network.

[0058] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, the data exchanged through the network is represented by technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

[0059] Optionally, the target terminal 101 in the embodiment of the present disclosure may also be referred to as a terminal device, UE (User Equipment). In a specific implementation, the terminal device may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device, etc. It should be noted that the specific type of the terminal device is not limited in the embodiment of the present invention.

[0060] The network side device may be a base station, a relay or an access point, etc. The base station may be a base station of 5G or later versions (e.g., 5G NR NB), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of the network side device is not limited in the embodiments of the present disclosure.

[0061] Those skilled in the art will know that Figure 1The number of target terminals 101, networks 102 and network-side devices 103 is merely illustrative. According to actual needs, there may be any number of target terminals 101, networks 102 and network-side devices 103, and the embodiments of the present disclosure are not limited to this.

[0062] Under the above system architecture, an uplink power control method is provided in an embodiment of the present disclosure. The method can be executed by any electronic device with computing and processing capabilities.

[0063] In some embodiments, the uplink power control method provided in the embodiments of the present disclosure can be executed by the target terminal of the above-mentioned system architecture; in other embodiments, the uplink power control method provided in the embodiments of the present disclosure can be implemented by the target terminal and the network side device in the above-mentioned system architecture through interaction.

[0064] Figure 2 A flow chart of an uplink power control method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the uplink power control method provided in the embodiment of the present disclosure includes the following steps S202 to S206.

[0065] S202: Acquire terminal capability parameters of the target terminal.

[0066] In some exemplary embodiments, the terminal capability parameter may be used to describe whether the target terminal supports a flexible carrier combination function.

[0067] In a possible implementation, the present disclosure may predefine a terminal capability parameter (flexiblecarrier combination-r21) to indicate whether the target terminal supports flexible carrier combination capability. If the target terminal reports the terminal capability parameter to the base station through the terminal capability reporting process (RRC UE capability transfer), it indicates that the target terminal supports the flexible carrier combination function.

[0068] It should be noted that for TDD (Time Division Duplex) or FDD (Frequency Division Duplex) spectrum combination methods, transmission is required based on DL / UL (Downlink / Uplink) carrier pairs.

[0069] In one possible implementation, Figure 3 FIG. 1 shows a schematic diagram of a TDD carrier pair and an FDD carrier pair. Figure 3 In the TDD carrier pair, the uplink and downlink use the same frequency band, while the FDD carrier pair can be symmetrical in uplink and downlink.

[0070] The flexible carrier combination function can avoid the above-mentioned limitation that the uplink and downlink are paired and symmetrical, and realize the flexible change of the number, frequency and bandwidth of uplink and downlink carriers, and flexibly configure them according to the actual application scenarios. When the uplink demand is large, the number of uplink carriers can be increased accordingly, and when the downlink demand is large, the number of downlink carriers can be increased accordingly.

[0071] In one possible implementation, Figure 4 A schematic diagram of a business scenario is shown.

[0072] In this Figure 4 It includes large downlink business scenarios and large uplink business scenarios. For large downlink business scenarios, for example, the downlink can use the 800MHz CC1 carrier, the 1.8GHz CC3 carrier and the 6GHz CC7-CC8 carrier to transmit data at the same time, and the uplink can use the 800MHz CC1 carrier to transmit data, which can significantly improve the downlink transmission speed.

[0073] For large downlink service scenarios, for example, the downlink can use the 800MHz CC1 carrier to transmit data, while the uplink can simultaneously use the 800MHz CC1 carrier, the 1.8GHz CC3 carrier and the 6GHz CC7-CC8 carrier to transmit data, thereby significantly improving the uplink transmission speed.

[0074] Therefore, in flexible carrier combination scenarios such as large downlink service scenarios and large uplink service scenarios, the uplink power solution needs to be redesigned.

[0075] It should be noted that after determining that the target terminal can support the flexible carrier combination function, the network side equipment can determine the frequency band f1 in which the uplink physical channel of the target terminal is located, and query whether the target terminal supports the corresponding f1 downlink carrier in the cell, that is, to determine whether the target terminal supports a downlink carrier with the same frequency band as the uplink in the current cell. The current cell is the cell where the target terminal is currently located.

[0076] In some exemplary embodiments, the uplink power control method provided by the embodiments of the present disclosure may also include: if the terminal capability parameter indicates that the target terminal supports the flexible carrier combination function, and the target terminal supports a downlink carrier with the same frequency band as the uplink, then determining the downlink path loss value accessed by the target terminal; determining the uplink path loss value based on the downlink path loss value; and determining the uplink power based on the uplink path loss value.

[0077] In an exemplary embodiment, when the target terminal supports a downlink carrier with the same frequency band as the uplink, the uplink path loss value can be approximately equivalently obtained by using the downlink path loss value calculated based on the reference signal of the downlink carrier with the same frequency. Then, the uplink power can be determined based on the uplink path loss value.

[0078] In some exemplary embodiments, the uplink power is determined based on the uplink path loss value, including: determining the uplink power based on the uplink path loss value, and at least one of the maximum transmit power of the target terminal, network configuration parameters, the number of resource blocks allocated for PUSCH transmission, a target adjustment value and a power control adjustment state value.

[0079] Exemplarily, the uplink path loss value, as well as the minimum value of at least one of the maximum transmit power of the target terminal, the network configuration parameters, the number of resource blocks allocated for PUSCH transmission, the target adjustment value and the power control adjustment state value can be taken as the uplink power.

[0080] In some possible implementations, the uplink power may be calculated according to the following formula (1).

[0081] P PUSCH =min{P CMAx , P o (j)+α(j)·PL(q)+10log 10 (2 μ ·M RB )+Δ TF +f b,f,c (i,l)} (1)

[0082] In formula (1), P PUSCH It can represent the uplink power, or the PP USCH It can be called the transmit power of PUSCH, the output of the power control unit, etc. CMAX It can represent the maximum transmit power of the target terminal, that is, the maximum RF transmit power allowed for each carrier. o (j) may represent a network configuration parameter, which may be used to describe the transmission power expected by the network side. It should be noted that the network configuration parameter may be a parameter configured through high-layer signaling.

[0083] Exemplarily, α(j) may represent a path loss compensation factor, and α(j) may be a network configurable parameter determined according to a partial path loss compensation value. PL(q) may represent an estimated value of the path loss, i.e., the uplink path loss value mentioned above. μ may represent a parameter related to the subcarrier spacing of PUSCH transmission. M RBIt can represent the number of resource blocks allocated for PUSCH transmission. TF It can represent a target adjustment value, and the value of the target adjustment value can be determined according to the modulation scheme and channel coding rate used for PUSCH transmission. b,f,c (i, l) may represent a power control adjustment state value, that is, a power adjustment caused by closed-loop power control, namely, TPC (Transmit Power Control Command).

[0084] In addition, j in formula (1) may represent the index of the configuration parameter set, and different values ​​of j correspond to different scheduling modes, i.e., different parameter sets. q may represent the index of the reference signal for calculating PL(q). i may represent the index of the PUSCH transmission opportunity. 1 may represent the index of the PUSCH power control adjustment state.

[0085] In some exemplary embodiments, the above-mentioned network configuration parameters can be obtained according to the sum of cell-level parameters and terminal-level parameters, wherein the cell-level parameters are used to describe the expected transmission power corresponding to all terminals on any carrier in the current cell, and the terminal-level parameters are used to describe the expected transmission power corresponding to the target terminal on any carrier in the current cell.

[0086] Exemplarily, the network configuration parameters may be determined according to the following formula (2).

[0087] P O_PUSCH,f,c (j) = P O_NOMINAL_PUSCH,f,c (j)+P O_UE_PUSCH,b,f,c (j) (2)

[0088] In formula (2), P O_PUSCH,f,c (j) is equal to P in formula (1) o (j), used to represent network configuration parameters. O_NOMINAL_PUSCH,f,c (j) can represent cell-level parameters. O_UE_PUSCH,b,f,c (j) may represent a terminal-level parameter. For example, both the cell-level parameter and the terminal-level parameter may be integers in the range of [-15, 16], in units of dBm. b may be used to represent the index of the terminal BWP (Bandwidth Part). f may be used to represent the carrier index. c may be used to represent the cell index.

[0089] In an exemplary embodiment, the cell-level parameter may represent the uplink power adjustment amount of the network side for all terminals on a certain carrier in any cell, that is, the transmission power expected by the network side. The terminal-level parameter may represent the uplink power adjustment amount of the network side for a certain terminal on a certain carrier in any cell, that is, the transmission power expected by the network side.

[0090] Among them, the cell-level parameters can be configured for all terminals in the cell first, and then the terminal-level parameters can be configured for each terminal respectively. The cell-level parameters and terminal-level parameters can be transmitted through RRC parameters, and sent from the network side device to the target terminal to inform the target terminal of the specific values ​​of the cell-level parameters and terminal-level parameters.

[0091] In an exemplary embodiment, the uplink power may be calculated by combining the above formula (1) and formula (2).

[0092] S204, if the terminal capability parameter indicates that the target terminal supports the flexible carrier combination function, and the target terminal does not support a downlink carrier with the same frequency band as the uplink, determine the downlink path loss value accessed by the target terminal and the path loss difference between the uplink and downlink.

[0093] In an exemplary embodiment, since the target terminal does not support a downlink carrier with the same frequency band as the uplink, the uplink path loss value cannot be directly approximated based on the downlink path loss value. At this time, the path loss difference between the uplink and downlink needs to be introduced.

[0094] It should be noted that the path loss difference represents the path loss difference between the uplink and downlink due to the different frequencies. Therefore, the uplink power of the target terminal can be calculated based on the downlink path loss value accessed by the target terminal and the path loss difference.

[0095] S206: Determine the uplink power of the target terminal according to the downlink path loss value and the path loss difference.

[0096] In some exemplary embodiments, the path loss difference value may be communicated based on a network configuration parameter, or may be communicated based on an estimate of the path loss.

[0097] In some exemplary embodiments, when a path loss difference is transmitted based on a network configuration parameter, the embodiment of the present disclosure provides a method for determining the uplink power of a target terminal based on a downlink path loss value and a path loss difference, which may include: determining a first network configuration parameter based on the path loss difference, the first network configuration parameter being used to indicate the network side's uplink transmit power configuration for the terminal; and determining the uplink power of the target terminal based on the first network configuration parameter and the downlink path loss value.

[0098] It should be noted that the first network configuration parameter can be used to indicate the uplink transmission power configuration of the terminal by the network side, or it can also be understood that the first network configuration parameter is used to describe the transmission power expected by the network side.

[0099] In some possible implementations, the first network configuration parameter may be equal to the sum of the path loss difference and the network configuration parameter.

[0100] Exemplarily, with the network configuration parameters shown in formula (2), the path loss difference can be transferred based on the terminal-level parameters in the network configuration parameters, thereby obtaining the first network configuration parameters.

[0101] Exemplarily, the first network configuration parameter can be expressed by the following formula (3).

[0107] In some exemplary embodiments, in the case where the path loss difference is transmitted based on network configuration parameters, the uplink power control method provided by the embodiments of the present disclosure may include: receiving a first signaling sent by a base station; and determining the path loss difference according to the first signaling.

[0108] Exemplarily, the field corresponding to the first signaling may have 4 bits in total, the unit may be dBm, and the range may be an integer within [-7, 8].

[0109] The embodiment of the present disclosure does not limit the name of the first signaling, and the name of the first signaling can be set based on experience or scenario. In some exemplary embodiments, the name of the first signaling can be, for example, delta-pathloss-r21.

[0110] In some exemplary embodiments, when a path loss difference is transmitted based on an estimated value of the path loss, determining the uplink power of the target terminal based on the downlink path loss value and the path loss difference may include: determining an uplink path loss value based on the downlink path loss value and the path loss difference; and determining the uplink power of the target terminal based on the uplink path loss value.

[0111] In some possible implementations, the uplink path loss value may be equal to the sum of the path loss value and the downlink path loss value.

[0112] Exemplarily, in this case, the calculation of the uplink power may be as shown in formula (5).

[0113] P PUSCH =min{P CMAX , P o (j)+α(j)·(PL(q) UL +ΔPL)+10·log 10 (2μ·M RB )+Δ TF +f b,f,c (i, l)} (5)

[0114] In formula (5), PL(q) ULIt can be used to represent the downlink path loss value. ΔPL can represent the path loss difference. In addition, the other parameters in formula (5) correspond to the corresponding parameters in the above formula (1), which will not be repeated here.

If the RRC parameter configuration field is 1, it means that the target terminal can use the path loss difference field during PUSCH power control.

[0119] In a possible implementation, when determining the uplink power, the target terminal may introduce a new parameter delta-Pathloss-r21. The base station configures the path loss difference for the target terminal through delta-Pathloss-r21 in the radio resource control of the physical uplink shared channel power control. At this time, the uplink power may be determined using formula (4).

[0120] In another possible implementation, a new parameter delta-Power-r21 may be introduced. The base station configures the path loss difference for the target terminal through delta-Power-r21 in the radio resource control of the physical uplink shared channel power control. In this case, the uplink power can be determined by formula (5).

[0121] In another possible implementation, no new parameters may be introduced. In this case, the base station may determine the path loss difference locally and convert the difference into a value by changing P O_UE_PUSCH,b,f,c The base station changes the value of P in the radio resource control of the physical uplink shared channel power control. O_UE_PUSCH,b,f,c(j) value to indicate the path loss difference. When the downlink carrier frequency of the path loss difference is greater than the PUSCH frequency, reduce P o (j) value; otherwise, increase P o (j)Value.

[0122] The method provided by the embodiment of the present disclosure can determine the uplink power by using the downlink path loss value accessed by the target terminal and the path loss difference between the uplink and downlink when the target terminal supports the flexible carrier combination function and the target terminal does not support the downlink carrier of the same frequency band as the uplink, thereby enabling targeted and flexible control of the uplink power in the flexible carrier combination scenario.
