Description

Uplink signal sending method, receiving method, device and system Technical field

This application relates to the field of wireless communication technology, and in particular to an uplink signal sending method, receiving method, device and system.

Background technique

With the development of mobile communication technology, more and more terminal devices can support multi-antenna communication, so that the terminal device can have multiple communication ports to improve the spectrum efficiency and system capacity of the communication system.

The multiple communication ports of the terminal device include multiple uplink ports for sending uplink signals to the network device. When sending an uplink signal, the terminal device will equally distribute the transmission power for multiple uplink ports, and send multiple sub-signals of the uplink signal obtained based on the same modulation coding scheme (MCS) to the network device through multiple uplink ports. . Specifically, each uplink port sends a sub-signal of an uplink signal, and multiple sub-signals sent by multiple uplink ports correspond to one uplink signal.

Generally, the MCS adopted by the terminal equipment is specified by the network equipment. Since the channel quality of the uplink channels corresponding to the multiple uplink ports is slightly different, when the multiple uplink ports of the terminal equipment transmit multiple sub-signals of the uplink signal with the same transmission power, the network equipment will The received power will also vary. Moreover, different MCSs have different code rates. When an uplink port with poor channel quality uses an MCS with a higher code rate, the network equipment will have a higher decoding error rate for the sub-signals sent by the uplink port.

Therefore, in an existing solution, the network equipment uses the uplink port with the worst channel quality as the main basis to designate the MCS for the terminal device, so that the uplink port with the worst channel quality can be used based on the sub-signals sent by the designated MCS. The network device decodes correctly. However, this method prevents the uplink port with better channel quality from sending the sub-signals of the uplink signal obtained based on the MCS with higher bit rate, which limits the transmission capacity of the uplink port with better channel quality and is not conducive to improving the uplink throughput of the communication system. the amount.

Generally, the terminal device 10 can receive the downlink signal sent by the network device 20 through all the downlink ports together to increase transmission reliability and increase the downlink throughput. And, sending an uplink signal to the network device 20 through one or more uplink ports. As shown in Figure 1, in the process of sending an uplink signal from the terminal device 10 to the network device 20, an uplink port, such as the uplink port 101U, can receive the transmitted signal by multiple antennas of the network device 20. The uplink port 101U and the network device 20 There can be 1 data stream transmission between devices. If four uplink ports are used to send signals to the network device 20, it can be increased to 4 data stream transmissions. It can be seen that under ideal circumstances, the terminal device 10 uses more uplink ports to transmit signals. When the network device 20 sends an uplink signal, the more beneficial it is to improve the uplink throughput of the terminal device 10.

Based on this, in a possible implementation manner, taking FIG. 1 as an example, the network device 20 may allocate a modulation coding scheme (Modulation Coding Scheme, MCS) to the terminal device 10. Furthermore, the terminal device 10 may divide the data to be transmitted into 4 parts, and obtain the 4 sub-signals corresponding to the uplink signal based on the MCS designated by the network device for it. It can also be considered that the terminal device 10 sends the uplink signal to the network device 20 Including the 4 sub-signals. And, the terminal device 10 allocates the same transmission power to the 4 uplink ports, and transmits the above-mentioned 4 sub-signals respectively through the 4 uplink ports. Assuming that the uplink signal includes sub-signal 1U, sub-signal 2U, sub-signal 3U and sub-signal 4U, the terminal device can send sub-signal 1U through uplink port 101U, sub-signal 2U through uplink port 102U, and sub-signal 3U through uplink port 103U , Send the sub-signal 4U through the uplink port 104U.

However, the communication channels between the uplink ports 101U to 104U and the network device 20 may have different channel qualities. For example, the terminal device 10 is a smart phone, and the user often covers one or more antennas when holding the terminal device 10, which causes the path loss of the uplink port corresponding to the covered one or more antennas to increase greatly. In the 1.8GHz frequency band The above test shows that the handheld has a 7-8dB attenuation of the uplink signal. For example, when the terminal device 10 in FIG. 1 is held by a user, it can be as shown in FIG. 3, where the dotted lines indicate perspective, that is, the antennas 101 to 104 are located on the back of the terminal device 10. When the terminal device 10 is held by the user, the back is in contact with the palm of the user . In Figure 3, the antenna 103 and the antenna 104 on the back of the terminal device 10 are covered by the palm of the user, while the antenna 101 and the antenna 102 are not covered by the palm of the user. This causes the path loss corresponding to the antenna 103 and the antenna 104 to be much greater than that of the antenna 101 and The path loss corresponding to the antenna 102.

In addition, due to the limitation of manufacturing process, production cost and other factors, the multiple antennas of the terminal device 10 may have different antenna gains, so that even if the same transmit power is allocated to different uplink ports, different uplink ports may have different antenna gains. The actual power of sending sub-signals between ports may also vary. Moreover, the pattern of multiple antennas cannot be guaranteed to be exactly the same. Even if the antenna calibration is completed in the initial direction, the antenna gain will still differ in some other directions. In the embodiment of the present application, the difference in gain between different antennas and the signal attenuation caused by hand-holding or shielding can be regarded as an impact on the channel quality between the uplink port and the network device 20.

Due to the difference in channel quality between different uplink ports, when the terminal device 10 transmits the sub-signals 1U to 4U with the same transmission power, the signal quality of the sub-signals 1U to 4U on the network device 20 side will also be different. For example, the terminal device sends a sub-signal 1U to the network device 20 through the uplink port 101U with a transmission power of 10W, and sends a sub-signal 2U to the network device 20 through the uplink port 102U with a transmission power of 10W, because the uplink port 101U and the network device 20 The path loss therebetween is greater than the path loss between the uplink port 102U and the network device 20, so that the received power of the network device 20 receiving the sub-signal 1U is less than the receiving power of the receiving sub-signal 2U. In actual use, the difference between the received power of different sub-signals by network equipment can even reach more than 10dB.

Because of this, the network device 20 will allocate MCS to the terminal device according to the channel quality between each uplink port of the terminal device 10. Specifically, there are multiple MCSs in wireless communication technologies, and different MCSs have different code rates. MCS is used to indicate the modulation mode and channel coding of PUSCH. When the channel quality is good (for example, the signal-to-noise ratio is high), the network equipment can allocate a higher code rate MCS to the terminal equipment to improve the uplink throughput. In addition, the network equipment can also adjust the MCS according to the initial block error rate (BLER) of the physical uplink shared channel (PUSCH). When the BLER exceeds/below a certain threshold, it can reduce/increase the MCS , So that the BLER is maintained at a certain level, such as 10%, so as to maintain a higher uplink throughput.

For the network device 20, if the MCS allocated to the terminal device 10 has a higher code rate, and the received power of any component signal sent by the terminal device 10 is small, the network device 20 cannot correctly decode the component. Signal, so that the network device 20 cannot correctly decode the uplink signal to which the sub-signal belongs. Based on this, the network device 20 usually allocates MCS to the terminal device 10 based on the transmission capability of the uplink port with the worst signal quality. For example, among the uplink ports 101U to 104U shown in Figure 1, the channel quality of 101U is the worst. The network device 20 will allocate MCS to the terminal device 10 based on the transmission capacity of 101U to ensure that it can receive the uplink port 101U to Sub-signals sent by 104U.

Using the above method, although the network device 20 can correctly decode the uplink signals sent by the terminal device 10 through multiple uplink ports, the above method does not fully utilize the transmission capacity of the uplink port with better channel quality, which limits the uplink throughput of the terminal device. The amount is further improved. In addition, this method does not make full use of the transmit power of the uplink port with better channel quality, which is not conducive to reducing the power consumption of the terminal equipment.

In addition, there is another possible implementation. The terminal device 10 may select an uplink port with the best channel quality from a plurality of uplink ports, and send an uplink signal to the network device 20 through the uplink port with the best channel quality. Using this method, although the power consumption of the terminal device 10 can be reduced to a certain extent, the method does not actually take advantage of the multi-antenna feature of the terminal device 10, and it also limits the further improvement of the uplink throughput of the terminal device 10.

It can be seen from the above two possible implementations that the terminal device 10 with multiple antennas cannot make full use of the characteristics of multiple uplink ports to improve the uplink throughput. Based on this, the embodiments of the present application provide an uplink signal transmission method and an uplink signal reception method, which are collectively referred to as an uplink signal transmission method hereinafter. By allocating different transmission powers to multiple uplink ports of the terminal device 10, the The multiple sub-signals sent may have the same or similar signal quality on the side of the network device 20, so as to improve the uplink throughput of the terminal device 10 and reduce the power consumption of the terminal device 10.

Specifically, for uplink ports with better channel quality, the transmission power can be reduced, which is beneficial to reduce the power consumption of the terminal device 10. For uplink ports with poor channel quality, the transmission power can be increased, which is beneficial to improve the terminal device 10. Upstream throughput. Generally, the channel quality between the uplink port of the terminal device 10 and the network device 20 can be represented by path loss. The smaller the path loss, the better the channel quality, and the greater the path loss, the worse the channel quality. Therefore, in the embodiment of the present application, the transmission power of any uplink port of the terminal device 10 for sending the sub-signal is related to the path loss between the uplink port and the network device 20. Detailed description will be given below in conjunction with specific embodiments.

FIG. 4 is a schematic diagram of a possible uplink signal transmission process provided by an embodiment of this application. As shown in FIG. 4, it mainly includes the following steps:

S201: The terminal device generates a first uplink signal, where the first uplink signal includes N first sub-signals.

Among them, the first uplink signal may be a signal carried on the physical uplink shared channel PUSCH channel, or it may be a sounding reference signal used for uplink beam management, codebook, and no codebook ( sounding reference signal, SRS). That is, the technical solution provided by the embodiment of the present application can be used to allocate the transmit power of each uplink port when the terminal device transmits the signal of the PUSCH channel or the SRS.

In the embodiment of the present application, the terminal device may determine whether to use multiple uplink ports to send the first uplink signal according to an instruction of the network device. If the network device instructs the terminal device to use multiple uplink ports to send the first uplink signal, the first uplink signal generated by the terminal device includes N first sub-signals, where the value of N corresponds to the number of uplink ports used correspond. Taking FIG. 1 as an example, if the network device 20 instructs the terminal device 10 to use 4 uplink ports to send the first uplink signal, the first uplink signal generated by the terminal device 10 includes 4 first sub-signals.

S202: The terminal device sends the i-th first partial signal to the network device through the i-th uplink port among the N uplink ports, where the i-th first transmission power of the i-th first partial signal sent by the terminal device is Related to the i-th path loss between the i-th uplink port and the network device; i is less than or equal to N, and N is a positive integer greater than 1.

In the embodiment of the present application, the i-th uplink port may be any uplink port in the terminal device, and the i-th first sub-signal is the first sub-signal sent by the terminal device through the i-th uplink port. The first transmission power is the transmission power of the terminal device sending the i-th first sub-signal, and the i-th path loss is the path loss between the i-th uplink port and the network device. For example, if the i-th uplink port is the uplink port 101U, the i-th first sub-signal is the sub-signal 1U sent by the terminal device 10 through the uplink port 101U, and the i-th first transmission power is the sub-signal 1U sent by the terminal device 10 The i-th path loss is the path loss between the uplink port 101U and the network device 20. It can be understood that the value of i in the embodiment of the present application is taken from 1 to N, that is, for each of the N uplink ports, the terminal device performs S202.

In the embodiment of the present application, the terminal device may respectively send the N first partial signals of the first uplink signal from the N uplink ports by using the same or different transmission power. Taking Figure 1 as an example, suppose the first uplink signal includes sub-signal 1U, sub-signal 2U, sub-signal 3U, and sub-signal 4U. Among them, terminal device 10 sends sub-signal 1U through uplink port 101U, and sub-signal 2U through uplink port 102U . If the path loss between the uplink port 101U and the network device 20 is the same as the path loss between the uplink port 102U and the network device 20, the transmission power of the terminal device 10 for sending the sub-signal 1U and the transmission power of the sub-signal 2U may be the same; if The path loss between the uplink port 101U and the network device 20 is different from the path loss between the uplink port 102U and the network device 20, and the transmission power of the terminal device 10 sending the sub-signal 1U may be different from the transmission power of the sub-signal 2U.

In a possible implementation manner, the i-th first transmit power is positively correlated with the i-th path loss estimate, and the i-th path loss estimate is the estimated path loss between the i-th uplink port and the network device . For example, in the above example, if the path loss between the uplink port 101U and the network device 20 is greater than the path loss between the uplink port 102U and the network device 20, the terminal device 10 sends a sub-signal 1U with a transmission power greater than that of a sub-signal 2U. power. Using the above method, different transmission powers can be allocated to the uplink port to compensate for the difference in path loss between the uplink port 101U and the uplink port 102U and the network device 20 on the network device 20 side receiving result, so that the network device 20 divides the signal The received power of 1U and sub-signal 2U are the same or similar. It can not only make the uplink port 101U with larger path loss use larger transmission power, so as to adapt to the MCS with higher bit rate, which is beneficial to improve the uplink throughput, but also can save the transmission power of the uplink port 102U with smaller path loss. Without reducing the MCS code rate, it is beneficial to reduce the power consumption of the terminal device 10. Further, when part of the antenna is held or blocked by the hand, the handheld terminal device adopting this solution can reduce the attenuation of the downlink received signal and the uplink transmitted signal from the antenna. In S202, the i-th first transmit power may be allocated by the terminal device itself, or may be allocated by the network device to the terminal device. Next, the first embodiment and the second embodiment are taken as examples to provide possible implementations of the above two cases respectively.

Example one

FIG. 5 is one of the schematic diagrams of a possible uplink signal transmission process provided by an embodiment of this application. As shown in FIG. 5, it mainly includes the following steps:

S301: The terminal device generates a first uplink signal. The specific implementation of this step is similar to that of S201, and will not be described again.

S302: The terminal assumes that the i-th path loss estimate value is obtained, where the i-th path loss estimate value is the estimate value of the i-th path loss above. Taking Figure 1 as an example, assuming that the uplink port 101U, the uplink port 102U, the uplink port 103U, and the uplink port 104U are used to send the first uplink signal, the terminal device 10 obtains the path loss between the uplink ports 101U to 104U and the network device 20, respectively estimated value.

For an antenna of the terminal device 10, the uplink channel between the uplink port corresponding to the antenna and the network device 20, and the downlink channel between the downlink port corresponding to the antenna and the network device 20, have similar path losses, so the current In the application embodiment, the terminal device 10 can estimate the path loss between the four uplink ports and the network device 20 according to the reception of the downlink signal sent by the network device 20, so as to obtain the path loss estimates corresponding to the N uplink ports. Taking the uplink port 101U in FIG. 1 as an example, in a possible implementation manner, the terminal device 10 can be based on the transmission power of the downlink signal sent by the network device 20, and the downlink port corresponding to the uplink port 101U, that is, the pair of downlink ports 101D The received power of the downlink signal obtains the estimated value of the path loss between the uplink port 101U and the network device 20.

S303: The terminal device allocates the i-th second transmission power to the i-th uplink port according to the i-th path loss estimation value; wherein, the i-th second transmission power is positively correlated with the i-th path loss estimation value. In the embodiment of the present application, the i-th second transmit power refers to the second transmit power allocated by the terminal device to the i-th uplink port.

It can be understood that the second transmit power allocated by the terminal device to the N uplink ports increases with the increase of the path loss corresponding to the uplink port. Taking Figure 1 as an example, suppose that the estimated path loss between uplink port 101U and network device 20 is 5dB, the estimated path loss between uplink port 102U and network device 20 is 6dB, and the estimated path loss between uplink port 103U and network device 20 is 6dB. The estimated path loss is 7dB, and the estimated path loss between the uplink port 104U and the network device 20 is 8dB. Then, the second transmission power allocated by the terminal device 10 to the uplink ports 101U to 104U is sequentially increased.

Furthermore, the terminal device 10 may respectively transmit sub-signals 1U to 4U according to the second transmission power allocated to the uplink ports 101U to 104U, respectively. In a possible implementation manner, as shown in S304 in FIG. 5, the terminal device 10 may also determine whether the i-th second transmission power is greater than the maximum of the i-th uplink port before sending the i-th first sub-signal. Transmit power; if yes, perform S305, send the i-th component signal according to the maximum transmit power, that is, the maximum transmit power of the i-th uplink port is the i-th first transmit power; if not, perform S306, according to the i-th The second transmission power transmits the i-th component signal, that is, the i-th second transmission power is the i-th first transmission power. Using the above method, the transmission power of the i-th sub-signal in the terminal device 10 is not greater than the maximum transmission power of the i-th uplink port.

In a possible implementation, the estimated received power corresponding to the i-th second transmit power allocated by the terminal device to the i-th uplink port and the j-th second transmit power allocated to the j-th uplink port The decibel power difference between the received power is not greater than the preset first threshold, where the estimated received power corresponding to the i-th second transmit power is calculated based on the i-th path loss estimate, and the j-th second The transmit power is calculated based on the j-th path loss estimate; j is less than or equal to N and not equal to i. The value of the first threshold can be set according to the environment of the communication system, usually a smaller value, that is, the estimated received power corresponding to the second transmission power allocated by the terminal equipment to the N uplink ports is the same or similar, so that The network device 20 may receive the N first sub-signals of the first uplink signal with the same or similar received power.

In the 5GNR protocol, the network device can allocate the total transmission power to the terminal device according to various factors such as the service type of the terminal device and the system environment, and indicate the total transmission power allocated to the terminal device through the first power information, as shown in the figure S307 in 5 shows. Generally, the first power information may be a transmit power control (TPC) command, and the TPC command is 2 bits, which may be used to indicate any of the four power adjustments. There are two types of power adjustment: cumulative type and absolute value type. For the cumulative power adjustment, the terminal device needs to determine the total transmit power according to the power adjustment currently indicated by the network device and the sum of the previous power control adjustments of the network device. For the absolute power adjustment, the terminal device can determine the total transmission power according to the power control adjustment currently indicated by the network device.

The TPC command may be carried in the downlink control information (DCI) on the physical downlink control channel (PDCCH), and the network device dynamically adjusts the total transmission power of the first uplink signal sent by the terminal device through the TPC command.

In the embodiment of this application, the TPC command for the network device to adjust the PUSCH transmission power of the terminal device can be carried in the DCI format 0_0 and DCI format 0_1 on the PDCCH, or can be carried in the DCI format 2_2, that is, the network device is carried in the DCI format 2_2 The TPC command of a group of terminal devices adjusts the total transmit power of a group of terminal devices. In addition, the TPC command used by the network device to adjust the power of the SRS transmitted by the terminal device can be multiplexed with the TPC command used to adjust the power of the PUSCH channel sent by the terminal device, that is, the network device cooperates with the power control terminal device to transmit the signals carried by the SRS and PUSCH. The network device can also use the TPC command independent of the PUSCH to adjust the total transmission power of the terminal device to send the SRS. For example, the TPC command for the network device to adjust the total transmission power of the SRS sent by the terminal device can be carried in DCI format 2_3 on the PDCCH channel and sent to Terminal Equipment.

If the first uplink signal is a signal carried on the PUSCH channel, the terminal device can determine the total transmission power allocated to it by the network device according to the following formula 1:

P _PUSCH,b,f,c (i,j,q _d ,l)

为PUSCH的带宽对发送功率的影响量；α _b,f,c(j)为路损补偿因子；PL _b,f,c(q _d)为终端设备与网络设备之间的下行路径损耗，对于具有多天线的终端设备，PL _b,f,c(q _d)可以为多个下行端口分别与网络设备之间的下行路径损耗的最小值；Δ _TF,b,f,c(i)为码率对发送功率的影响量；f _b,f,c(i,l)为网络设备通过TPC命令所指示的功率调整量。 Among them, P _{PUSCH, b, f, c} (i, j, q _d , l) is the total transmission power allocated by the network equipment for the terminal equipment to send the first uplink signal; P _{CMAX, f, c} (i) is the terminal equipment The maximum transmit power of P _{O_PUSCH, b, f, c} (j) is the static operating point of the network equipment;

Is the influence of PUSCH bandwidth on transmit power; α _{b, f, c} (j) is the path loss compensation factor; PL _{b, f, c} (q _d ) is the downlink path loss between terminal equipment and network equipment, for For terminal equipment with multiple antennas, PL _{b, f, c} (q _d ) can be the minimum value of the downlink path loss between multiple downlink ports and the network device; Δ _{TF, b, f, c} (i) is the code The amount of influence of the transmission power rate; f _{b, f, c} (i, l) is the power adjustment amount indicated by the network device through the TPC command.

Similarly, if the first uplink signal is an SRS, the terminal device 10 can determine the total transmission power allocated to it by the network device 20 according to the following formula 2:

Among them, P _SRS,b,f,c (i,q _s ,l) is the total transmission power allocated by the network equipment for the terminal device to send the first uplink signal; P _{O_SRS,b,f,c} (q _s ) is the network The static operating point of the equipment; 10log ₁₀ (2 ^μ ·M _SRS,b,f,c (i) is the influence of the bandwidth of the SRS on the transmission power; α _SRS,b,f,c (q _s ) is the path loss compensation Factor; PL _{b, f, c} (q _d ) is the downlink path loss between the terminal device and the network device. For a terminal device with multiple antennas, PL _{b, f, c} (q _d ) can be multiple downlink ports respectively The minimum value of the downlink path loss with the network device; h _{b, f, c} (i, l) is the power adjustment amount indicated by the network device through the TPC command.

After the terminal device obtains the total transmit power allocated by the network device to the network device according to the first information, it can allocate corresponding values to the N uplink ports according to the estimated path loss and the total transmit power between the N uplink ports and the network device. The second transmission power of the N uplink ports is such that the sum of the respective second transmission powers of the N uplink ports is not greater than the total transmission power, thereby conforming to the total transmission power adjustment rule specified by the communication protocol.

For example, the terminal device may allocate the second transmission power to the N uplink ports according to the allocation rule shown in the following formula 3:

为P _i-1的线性功率值；

为总发送功率P _SUM的线性功率值，如上述公式一和公式二所计算获得的总发送功率为总发送功率的分贝功率值，因此终端设备在根据公式一或公式二获取总发送功率的分贝功率值后，还需要将分贝功率值转换为线性功率值；α为路损补偿因子，若第一上行信号为PUSCH信道所承载的信号，则α为上述α _b,f,c(j)，若第一上行信号为SRS，则α为上述α _SRS,b,f,c(q _s)。 Wherein, Pi _-1 is the decibel power value of the i-th second transmission power, i=[1, N];

Is the linear power value of _Pi-1 ;

Is the linear power value of the total transmission power P _SUM . The total transmission power calculated as the above formula 1 and formula 2 is the decibel power value of the total transmission power. Therefore, the terminal device obtains the total transmission power in decibels according to the formula 1 or formula 2. After the power value, the decibel power value needs to be converted into a linear power value; α is the path loss compensation factor, if the first uplink signal is the signal carried by the PUSCH channel, then α is the above α _{b, f, c} (j), If the first uplink signal is an SRS, then α is the above α _SRS,b,f,c (q _s ).

Through the method provided in the first embodiment, the terminal device can estimate the path loss between the N uplink ports and the network device respectively, and allocate transmit power to each uplink port based on the estimated path loss, so that the network device can The N sub-signals of the uplink signal have the same or similar received power, which can increase the transmit power of the uplink port with a larger path loss, thereby increasing the uplink throughput, and reduce the transmit power of the uplink port with a smaller path loss. Without reducing the MCS code rate, the power consumption of the terminal equipment is reduced.

Example two

FIG. 6 is the second schematic diagram of a possible uplink signal transmission process provided by an embodiment of this application. As shown in FIG. 6, it mainly includes the following steps:

S401: The network device allocates a corresponding decibel power difference value to the first uplink port according to the path loss corresponding to the first uplink port.

Among them, the decibel power difference corresponding to the first uplink port is used to indicate the decibel power difference between the third transmit power of the first uplink port and the third transmit power of the reference port, and the first uplink port is the N number of terminal equipment Any one of the uplink ports except the reference port. In other words, the network device determines an uplink port from the N uplink ports of the terminal device as a reference port, and sequentially determines the third transmit power of the other uplink ports in the N uplink ports with respect to the reference port. Decibel power difference of the third transmit power.

In this embodiment of the application, the decibel power difference corresponding to the first uplink port is positively correlated with the path loss between the first uplink port and the network device, that is, the greater the path loss between the first uplink port and the network device , The greater the difference in decibel power allocated by the network equipment to the first uplink port, the smaller is on the contrary, so that the uplink port with the larger path loss is allocated more transmit power, and the uplink port with the smaller path loss is allocated smaller Transmit power.

Taking Figure 1 as an example, suppose 101U to 104U in the terminal device 10 are used to send the first uplink signal, and the network device determines that the uplink port 102U is the reference port, and the network device 20 will also be the uplink port 101U, the uplink port 103U, and the uplink port. 104U allocates the corresponding decibel power difference. Among them, the decibel power difference corresponding to the uplink port 101U is the decibel power difference between the third transmit power of the uplink port 101U and the third transmit power of the uplink port 102U, and the decibel power difference corresponding to the uplink port 103U and the uplink port 104U respectively The value is similar to that of the upstream port 101U, and will not be repeated here.

In a possible implementation manner, the network device may obtain the path loss corresponding to the first uplink port according to the following method, as shown in S407 in FIG. 6, before the network device allocates the corresponding decibel power difference for the first uplink port Receive the second uplink signal sent by the terminal device. In the embodiment of the present application, the second uplink signal includes M second sub-signals. Before sending the first uplink signal, the terminal device sends the M second sub-signals of the second uplink signal to the network device through the M uplink ports. signal. Wherein, M is greater than or equal to N, and the M uplink ports include N uplink ports.

In the embodiment of the present application, the network device may obtain the path loss corresponding to the first uplink port according to the second uplink signal. Among them, the path loss can be either the estimated value of the path loss or the equivalent path loss.

Specifically, in a possible implementation manner, after receiving the second uplink signal sent by the terminal device, the network device may obtain the transmission power of the second sub-signal of the second uplink signal sent by the terminal device through the first uplink port, according to The terminal device sends the transmission power of the second sub-signal through the first uplink port, and estimates the path loss corresponding to the first uplink port on the received power of the second sub-signal to obtain the path loss estimation value corresponding to the first uplink port.

For example, the network device can obtain the estimated path loss corresponding to the first uplink port according to the rule shown in formula 4:

PL _p =P _p -P _p ⁰ (Formula 4)

Among them, PL _p is the estimated path loss value corresponding to the first uplink port, P _p ⁰ is the received power of the network device to the second sub-signal sent through the first uplink port, and P _p is the terminal device sending the first uplink port through the first uplink port. The transmit power of the bipartite signal.

Taking Fig. 1 as an example, suppose that the network device 20 obtains that the transmission power of the second sub-signal 1u transmitted by the terminal device through the uplink port 10 is 8 dBm, and the receiving power of the second sub-signal 1u received by the network device is 6 dBm, then the network device 20 can obtain the uplink The estimated path loss corresponding to port 101U is 2dB.

In another possible implementation manner, the network device may obtain the corresponding signal to the first uplink port according to the transmission power of the terminal device through the first uplink port of the second sub-signal and the received signal-to-noise ratio of the second sub-signal. The equivalent path loss; where the equivalent path loss corresponding to the first uplink port is used to characterize the path loss between the first uplink port and the network device, and the sum of the decibel power of the noise signal received by the network device.

For example, the network device can obtain the equivalent path loss corresponding to the first uplink port according to the rule shown in formula 5:

PL _p ′=P _p -R _p (Equation 5)

Among them, PL _p ′ is the equivalent path loss corresponding to the first uplink port, and R _p is the signal-to-noise ratio of the second sub-signal received by the network device and sent through the first uplink port. It can be understood that when the network device receives the second sub-signal, it will inevitably receive a certain noise signal. Whether the network device can correctly decode the second sub-signal is also related to the signal strength of the noise signal received by the network device. In the embodiment of the present application, the signal-to-noise ratio of the second sub-signal received by the network device can be expressed as the decibel power difference between the second sub-signal received by the network device and the noise signal, which can be obtained by combining formula 4, the equivalent path The loss is equivalent to the sum of the path loss and the decibel power of the noise signal.

In addition, the network device can also estimate the path loss between each of the M uplink ports according to the M second sub-signals, and determine that the terminal device is used to send the first uplink signal according to the path loss between each of the M uplink ports. The uplink port. Taking Figure 1 as an example, suppose that the terminal device 10 sends four second sub-signals to the network device 20 through the uplink ports 101U to 104U, and the network device 20 determines that the path loss between the uplink port 103U and the network device 20 is too large, and the network device 20 determines The uplink port 101U, the uplink port 102U, and the uplink port 104U are next uplink ports used to send the first uplink signal, and indicate the terminal device 10.

S402: The network device sends the reference port identifier of the reference port and the second power information to the terminal device; where the second power information is used to indicate the decibel power difference corresponding to the first uplink port.

In the embodiment of the present application, the second power information can be delivered through radio resource control (radio resource control, RRC) signaling, or MAC CE, or DCI signaling, or can be delivered along with the TPC command. In a possible implementation, if there is not much difference between the second power information of the first uplink signal and the second power information of the second uplink signal, the network device may not perform S402, and the terminal device may perform S402 according to the second uplink signal. The second power information of the signal sends the first uplink signal, thereby reducing air interface signaling overhead.

Since the network device can obtain the accurate reception of the second sub-signal, the power control performed by the network device has a higher accuracy; and compared with the existing wireless communication protocol, the network device only needs to increase the signaling for sending the second power information , So the modification to the existing air interface signaling is minor.

S403: The terminal device obtains the third transmit power of the N uplink ports respectively according to the second power information. Wherein, the decibel power of the third transmission power of the first uplink port is the sum of the decibel power difference corresponding to the first uplink port and the third transmission power of the reference port.

For example, the uplink port 102U in FIG. 1 is a reference port, the third transmission power is 10 dBm, and the decibel power difference corresponding to the uplink port 101U in the second power information is 2 dB, and the third transmission power of the uplink port 101U is 12 dBm.

In a possible implementation manner, as shown in S402 in FIG. 6, the network device may also send the first power information to the terminal device to indicate to the terminal device the total transmit power allocated for the terminal device. The terminal device can obtain the total transmission power according to the first power information. For specific implementation, refer to Embodiment 1, which will not be repeated.

Furthermore, the terminal device may obtain the third transmission power of the N uplink ports respectively according to the total transmission power and the second power information.

In a possible implementation manner, the sum of the third transmission power of the N uplink ports is not greater than the total transmission power. For example, the terminal device may obtain the third transmit power of the N uplink ports according to the following formula 6:

为P′ _i-1的线性功率值，P _a为参考端口的第三发送功率，P _n′为N个上行端口中除参考端口之外的其它任一上行端口的第三发送功率，ΔPL _n为上行端口n对应的分贝功率差值。 Where P′ _i-1 is the decibel power value of the i-th third transmission power, i=[1, N];

Is the linear power value of P′ _i-1 , P _a is the third transmit power of the reference port, P _n ′ is the third transmit power of any uplink port except the reference port among the N uplink ports, ΔPL _n Is the decibel power difference corresponding to the uplink port n.

In another possible implementation manner, the terminal device may obtain the third transmission power of the reference port according to the total transmission power, and then obtain the third transmission power of other uplink ports according to the second power information. For example, the terminal device may also obtain the third transmit power of the N uplink ports according to the following formula 7:

Among them, the first equation is used to indicate that the third transmit power of the reference port is the average value of the total transmit power among N uplink ports. The terminal device can determine the third transmit power of the reference port according to the first equation and the total transmit power, and then determine the third transmit power of the N-1 uplink ports among the N uplink ports except the reference port according to the second equation. Three transmission power.

In another possible implementation manner, as shown in S402 in FIG. 6, the network device may also send third power information to the terminal device to indicate the third power information of the reference port to the terminal device. For example, the network device obtains the third transmission power of the reference port according to the average value of the total transmission power allocated to the terminal device in the N uplink ports, and sends the third power information to the terminal device.

The terminal device receives the third power information, and obtains the third transmit power of the reference port according to the third power information. In the embodiment of the present application, the third power information is similar to the first power information, and it can also be the power adjustment amount indicated by the TPC command. The terminal device can obtain the third power of the reference port based on the process similar to the above-mentioned obtaining the total transmit power. Transmission power, this will not be repeated here.

The terminal device can then obtain the third transmission power of the N-1 uplink ports except the reference port among the N uplink ports according to the third transmission power of the reference port and the foregoing second power information.

After the terminal device obtains the third transmission powers respectively corresponding to the N uplink ports, in a possible implementation manner, the N first sub-signals can be respectively transmitted according to the third transmission power. In another possible implementation manner, As shown in S404 in FIG. 6, the terminal device determines whether the i-th third transmit power of the i-th uplink port is greater than the maximum transmit power of the i-th uplink port. If yes, execute S405 to send the i-th first sub-signal according to the maximum transmit power of the i-th uplink port; if not, execute S406 to send the i-th first sub-signal according to the i-th third transmission power . To ensure that the power of the terminal device sending the i-th first sub-signal does not exceed the maximum sending power of the i-th uplink port.

In the two implementation manners for calculating the path loss provided by the embodiments of the present application, the network device can obtain the transmission power of the second sub-signal sent by the terminal device through the first uplink port in the following manner:

As shown in S407 in FIG. 4, the terminal device may also send power headroom information to the network device, where the power headroom information is used to indicate the power headroom (PH) of the terminal device. Wherein, the power headroom information may be carried in the second uplink signal, or may be reported by the terminal device through other uplink signals, which is not limited in the embodiment of the present application.

Generally, the power headroom information may be a power headroom report (PHR). The terminal device can report the power headroom of the terminal device to the network device in the PHR MAC (medium access control) CE (control element, control element) of the PUSCH channel.

The network device can determine the current transmit power of the terminal device relative to the maximum transmit power of the terminal device according to the power headroom reported by the terminal device to determine how much power remains, and then determine the total actual transmit power of the terminal device to send the second uplink signal.

Furthermore, the network device may obtain the M fourth transmission powers of the M second sub-signals sent by the terminal device according to the total actual transmission power; wherein the sum of the M fourth transmission powers is the total actual transmission power. Specifically, the transmission power of the terminal device for sending the M second sub-signals is also controlled by the network device. As shown in S402 and S403, the network device can instruct the terminal device to send the N first sub-signals through the second power information. Based on this, the network device can also obtain second power information (hereinafter referred to as the second power information of the second uplink signal) used to indicate the transmission power of the M second sub-signals, and combine the above-mentioned total actual transmission power to obtain the terminal equipment The transmit power of M second sub-signals.

The first and second embodiments both allocate transmission power to the N uplink ports of the terminal device from the perspective of path loss, so that the network device has the same or similar received power for the N first partial signals of the first uplink signal. In addition, the embodiment of the present application also provides another uplink signal transmission method. The network device can adjust the transmission power of the N first sub-signals sent by the terminal device according to the received signal quality of the N sub-signals of the second uplink signal, for example The following example three is shown.

Example three

FIG. 7 is the third schematic diagram of a possible uplink signal transmission process provided by an embodiment of this application. As shown in FIG. 7, it mainly includes the following steps:

S501: The network device receives the second uplink signal sent by the terminal device. For specific implementation, refer to Embodiment 2, which will not be repeated here.

S502: The network device obtains quality parameters corresponding to the N uplink ports according to the received N second partial signals of the second uplink signal. Wherein, the i-th quality parameter is the quality parameter of the second sub-signal received by the network device and sent by the terminal device through the i-th uplink port.

In the embodiment of the present application, the quality parameter is a parameter used to indicate signal quality. For example, the i-th quality parameter may include the received power of the second sub-signal sent by the network device to the i-th uplink port, and may also include the second sub-signal received by the network device and sent by the terminal device through the i-th uplink port. Signal-to-noise ratio. As an example, it is convenient to describe, and the following takes the received power as an example for description.

S503: The network device allocates the i-th power adjustment amount to the i-th uplink port according to the i-th quality parameter.

It should be understood that the power adjustment amount in the embodiment of the present application can be either a positive value, that is, increasing the transmission power, or a negative value, that is, reducing the transmission power. In the embodiment of the present application, the i-th power adjustment amount is negatively related to the signal quality of the second sub-signal received by the network device and sent by the i-th uplink port. In other words, the worse the signal quality of the second sub-signal received by the network device and sent by the i-th uplink port, the greater the i-th power adjustment amount allocated by the network device to the i-th uplink port. On the contrary, the network device The better the signal quality of the second sub-signal received and sent by the i-th uplink port is, the smaller the i-th power adjustment amount allocated by the network device to the i-th uplink port.

As shown in S501 in FIG. 7, the terminal device also sends power headroom information to the network device. In the third embodiment, the power headroom information sent by the terminal device to the network device includes the power headroom of the i-th uplink port. After receiving the power headroom information reported by the terminal equipment, the network device can allocate the i-th power adjustment amount to the i-th uplink port according to the i-th quality parameter and the power headroom of the i-th uplink port. The power adjustment amount is not greater than the power headroom of the i-th uplink port.

Specifically, the power headroom of the i-th uplink port can be represented by the following formula 8:

PH ⁱ ＝P _{i, CMAX} -P ⁱ (Formula 8)

Among them, PH ⁱ is the power headroom of the i-th uplink port, P _{i, CMAX} are the maximum transmission power of the i-th uplink port, and P ⁱ is the transmission power of the terminal device to send the second sub-signal through the i-th uplink port. When the second uplink signal is a signal carried by the PUSCH channel, PH ⁱ is type 1 (type 1), and when the second uplink signal is an SRS, PH ⁱ is type 3 (type 3).

Taking Figure 1 as an example, in a possible implementation manner, the power headroom information sent by the terminal device 10 to the network device 20 may be as shown in Figures 8a and 8b, where Figure 8a shows that the second uplink signal is the PUSCH channel. The signal carried is the power headroom information reported by the terminal device 10, and FIG. 8b is the power headroom information reported by the terminal device 10 when the second uplink signal is an SRS. Among them, R is a reserved field. As shown in FIG. 8a and FIG. 8b, the power headroom information includes the power headroom of each uplink port in the terminal device, and each power headroom occupies 6 bits. PH ¹ _type1 to PH ⁴ _type1 in Fig. 8a, and PH ¹ _type3 to PH ⁴ t _{ype3 in} Fig. 8b. In addition, as shown in Figure 8a and Figure 8b, the power headroom information can also include the maximum transmit power of the uplink ports 101U to 104U, which are respectively P _{1, CMAX} , P _{2, CMAX} , P _{3, CMAX} and P _{4, CMAX} . In the power headroom information, the power headrooms of the uplink ports are arranged in the default order. For example, in Figure 8a and Figure 8b, the port identifiers are arranged in ascending order, so that the network device can distinguish between different power headrooms. Uplink port.

In another possible implementation manner, the power headroom information sent by the terminal device 10 to the network device 20 may also be as shown in FIG. 8c and FIG. 8d, where FIG. 8c is when the second uplink signal is a signal carried by the PUSCH channel. For the power headroom information reported by the terminal device 10, FIG. 8d is the power headroom information reported by the terminal device 10 when the second uplink signal is an SRS. In the power headroom information shown in Figure 8c and Figure 8d, only the power headroom and maximum transmit power of the reference port are reported, and the power headroom and maximum transmit power of other uplink ports are reported in a differential form. As shown in Figure 8c, the reference port is the uplink port 101U, the differential PH ² _type3 represents the difference between the power headroom of the uplink port 102U and the power headroom PH ¹ _{type3 of the} uplink port 101U, and the difference P _{2, CMAX} represents the uplink port 102U The difference between the maximum transmission power of the uplink port 101U and the maximum transmission power P _{1, CMAX} . Other uplink ports are similar, so I won’t repeat them. The network device can obtain the power headroom and maximum transmission power of other uplink ports on the basis of the power headroom and maximum transmission power of the reference port. Comparing Figure 8a and Figure 8c, it can be seen that the use of a differential method can shorten the occupied signaling resources.

In the embodiment of the present application, in the power headroom information reported by the terminal device, the reference port may be the reference port in the second power information of the second uplink signal, for example, in the second power information of the second uplink signal, the reference port The port is the uplink port 101U, and the reference port in the power headroom information reported by the terminal device 10 is the uplink port 101U.

In another possible implementation manner, the power headroom information may also only include the power headroom of the reference port, and the network device may obtain the PH of each other uplink port according to the second power information of the second uplink signal. For example, in the power headroom information, the reference port is the uplink port 102U, the power headroom when the uplink port 102U sends the second sub-signal is 6dB, and in the second power information of the second uplink signal, the reference port is still the uplink port 102U If the decibel power difference corresponding to the uplink port 103U is 4dB, and the maximum transmit power of the uplink ports 102U and 103U are the same, it can be determined that the power margin of the uplink port 103U is 6dB-4dB=2dB. It can be understood that the reference port in the power headroom information may also be other default uplink ports, and the network device may still calculate the power headroom of each uplink port according to the second power information of the second uplink signal.

In addition, the power headroom information may also include only the minimum value of the power headrooms of the N uplink ports, and the power adjustment amount allocated by the network device to the N uplink ports cannot be greater than the minimum value. In this way, the occupation of signaling resources can be reduced, and the power adjustment amount allocated to the uplink port by the network device can be prevented from exceeding the power headroom of the uplink port.

S504: The network device sends fifth power information to the terminal device.

Wherein, the fifth power information is used to indicate the power adjustment amount allocated by the network device to the N uplink ports respectively. In the embodiment of this application, the fifth power information may be a TPC command, and the network device may extend the TPC command format in the existing DCI0_0, DCI0_1, DCI2_2, and DCI2_3, and may also define a new DCI format, a new DCI The format contains the TPC commands allocated for each uplink port.

S505: The terminal device receives the fifth power information sent by the network device, obtains the i-th power adjustment amount allocated by the network device to the i-th uplink port according to the fifth power information, and adjusts the i-th uplink according to the i-th power adjustment amount The i-th transmit power of the port.

In the embodiment of the present application, the terminal device can obtain the i-th transmit power according to the rules shown in Formula 1 and Formula 2. The difference between obtaining the total transmit power of PUSCH is that P _CMAX,f,c (i) becomes the maximum transmit power of the i-th uplink port, and PL _b,f,c (q _d ) is the i-th uplink port and network The path loss between devices, f _{b, f, c} (i, l) is the power adjustment amount allocated by the network device to the i-th uplink port. The difference between obtaining the total transmission power of the SRS is similar to the above difference, and will not be repeated here.

In a possible implementation manner, before performing S504, the network device may also construct one or more port sets according to the quality parameters corresponding to the N uplink ports; any port set may include one or more uplink ports If the port set includes multiple uplink ports, the difference between the quality parameters corresponding to any two uplink ports in the port set is not greater than the preset second threshold. Taking Figure 1 as an example, if the quality parameter of the second sub-signal sent by the uplink port 101U received by the network device 20 is the same or similar to the quality parameter of the second sub-signal sent by the uplink port 102U received, the uplink port 101U and the upstream port 102U are divided into the same port set, which is assumed to be set 1. And, the network device 20 sends the port set information to the terminal device 10, the port set information includes the set identifier of the set 1 and the port identifiers of the uplink ports included in the set 1, such as the port identifier of the uplink port 101U and the port identifier of the uplink port 102U.

Based on this, the network device can allocate the power adjustment amount in the unit of set 1, that is, allocate the power adjustment amount to set 1. The power adjustment amount can be used as the power adjustment amount of the uplink port 101U and the power adjustment amount of the uplink port 102U in the set 1. The fifth power information sent by the network device to the terminal device may include the set identifier of set 1 and the power adjustment amount allocated to set 1. When performing S505, the terminal device can determine one or more uplink ports corresponding to the set identifier in the port set information, such as the above-mentioned uplink port 101U and uplink port 102U. Adjust the transmit power of one or more uplink ports according to the power adjustment amount corresponding to the set identifier in the fifth power information, that is, the terminal device 10 adjusts the transmission of the uplink port 101U and the uplink port 102U according to the power adjustment amount corresponding to the set 1. power.

By adopting the above method, the overhead of uplink and downlink signaling can be reduced when there are many uplink ports. For example, the terminal device 10 has 4 uplink ports, but as the terminal device 10 of a smart phone, its uplink ports can only be covered and uncovered. By setting the second threshold reasonably, the covered uplink ports can be divided into One group, the uncovered uplink ports are divided into one group, and power control is performed on the two groups respectively.

In the embodiment of the present application, the network device may send the port set information to the terminal device through the PDCCH channel, and may also send the port set information to the terminal device through RRC signaling or MAC CE.

When sending port set information through the PDCCH channel, the following DCI format can be used, or the following fields can be added to the existing DCI format:

TPC-group SEQUENCE(SIZE(nrOfTxPort)) OF TPC-groupID OPTIONAL;

When sending port set information through RRC signaling, the following information elements can be added to the RRC reconfiguration message:

TPC-group SEQUENCE(SIZE(nrOfTxPort)) OF TPC-groupID OPTIONAL;

Among them, TPC-group is port set information, which includes nrOfTxPort elements, where nrOfTxPort represents the number of uplink ports used to send the first uplink signal, and the corresponding uplink port identifiers are 0...nrOfTxPort-1. The value of nrOfTxPort in this embodiment of the application can be N. TPC-groupID is the port collection ID corresponding to the port ID, with a value ranging from 0 to maxNrOfTPCGroup-1, and maxNrOfTPCGroup represents the maximum number of port collections. OPTIONAL indicates that the cell is optional, and the network device can send the cell to adjust the transmit power of the uplink port in the form of port aggregation, or not to send the cell, which means that the uplink port is not adjusted in the form of port aggregation. Transmission power.

For example, suppose that the uplink ports 101U and 102U belong to port set 1, and the uplink ports 103U and 104U belong to port set 2, then TPC-group can be 0011, where "0" is the set identifier of port set 1, and "1" bit port Set ID of set 2. For another example, assuming that the uplink ports 101U, 102U, and 104U belong to set 1, and the uplink port 103U belongs to set 2, the TPC-group may be 0010.

When sending port collection information through MAC CE, a new MAC CE can be set. Taking nrOfTxPort equal to 4 and maxNrOfTPCGroup equal to 4 as an example below, a format that can be adopted by MAC CE is given. In FIG. 9, TPC-groupIDi represents the set identifier of the port set to which port i belongs. oct1 represents a bit composed of 8 bits. Taking the assumption that the uplink ports 101U and 102U belong to set 1, and the uplink ports 103U and 104U belong to set 2 as an example, the values of TPC-groupID1 and TPC-groupID2 in Figure 9 are 0 (the port set identifier of set 1), TPC-groupID3 and The value of TPC-groupID4 is 1 (port group identifier of group 2).

S506: The terminal device sends the i-th first sub-signal of the first uplink signal according to the adjusted i-th transmit power; the first uplink signal includes N first sub-signals. The specific example is similar to the first embodiment and the second embodiment, which will not be repeated here.

Using the method provided in the third embodiment, the network device performs independent power control on different ports/port sets of the terminal device to balance the received power of the N first sub-signals, thereby increasing the uplink throughput and reducing the power consumption of the terminal device. Moreover, since the network device has complete information on the reception of the second sub-signal, the power control performed by the network device has a higher precision. Especially in the FDD frequency band, due to the unsatisfactory uplink and downlink reciprocity, power control by network equipment has a more significant accuracy advantage.
