Description

Uplink signal sending method, receiving method, device and system

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method, a device, and a system for transmitting and receiving an uplink signal.

Background

With the development of mobile communication technology, more and more terminal devices are capable of supporting multi-antenna communication, so that the terminal devices may have multiple communication ports to improve the spectrum efficiency and system capacity of the communication system.

The plurality of communication ports of the terminal device include a plurality of uplink ports for transmitting uplink signals to the network device. When transmitting an uplink signal, the terminal device may equally allocate transmission power to a plurality of uplink ports, and transmit a plurality of sub-signals of the uplink signal obtained based on the same Modulation Coding Scheme (MCS) to the network device through the plurality of uplink ports. Specifically, each upstream port transmits a sub-signal of an upstream signal, and a plurality of sub-signals transmitted by a plurality of upstream ports correspond to one upstream signal.

Typically, the MCS employed by the terminal device is specified by the network device. Since the channel quality of the uplink channels corresponding to the plurality of uplink ports are slightly different, when the plurality of uplink ports of the terminal device transmit a plurality of sub-signals of the uplink signal with the same transmission power, the reception power of the network device for the plurality of sub-signals will also be different. Moreover, different MCSs have different code rates, and when an uplink port with poor channel quality adopts an MCS with a higher code rate, the network device may have a higher decoding error rate for the sub-signal sent by the uplink port.

Therefore, in one conventional scheme, the network device specifies an MCS for the terminal device based mainly on the uplink port with the worst channel quality, and enables the network device to correctly decode the packet signal transmitted by the uplink port with the worst channel quality based on the specified MCS. However, the method makes the uplink port with better channel quality unable to send the sub-signal of the uplink signal acquired based on the MCS with higher code rate, thereby limiting the transmission capability of the uplink port with better channel quality and being not beneficial to improving the uplink throughput of the communication system.

Fig. 1 is a schematic architecture diagram of a possible communication system to which the embodiment of the present application is applicable. The communication system shown in fig. 1 includes a network device 20 and a terminal device 10. It should be understood that fig. 1 is only an architecture diagram of a communication system, the number of network devices and the number of terminal devices in the communication system are not limited in this embodiment, and the communication system to which this embodiment of the present application is applied may include other devices, such as a core network device, a wireless relay device, a wireless backhaul device, and the like, besides the network devices and the terminal devices, and this embodiment of the present application is also not limited. In addition, the network device in the embodiment of the present application may integrate all functions into one independent physical device, or may distribute the functions over a plurality of independent physical devices, which is not limited to the embodiment of the present application. In addition, the terminal device in the embodiment of the present application may be connected to the network device in a wireless manner.

In one possible implementation, the terminal device 10 and the network device 20 shown in fig. 1 may be devices in a radio access network. Fig. 2 is a network structure of a radio access network applicable to the embodiment of the present application, where the access network is divided into cells, and a terminal device in each cell and a network device in the cell perform signaling and data interaction through an air interface link. The network device may be based on a plurality of Access technologies, depending on the network standard, for example, in 5G NR, the network device 20 may be a gNB (next Generation Node B) and may use an OFDMA (Orthogonal frequency division multiple Access) multiple Access method.

Further, the network device 20 may also include, but is not limited to, other types of base stations (e.g., base station NodeB, evolved base station eNodeB), base stations or network devices in future communication systems, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes), and so on. The network device 20 may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. The network device 20 may also be a small station, a transmission node (TRP), or the like. Although the application is not so limited.

The terminal device 10 is a device with a wireless transceiving function, and can be deployed on land, including indoors or outdoors, hand-held, worn or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). For example, the terminal device 10 may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in home (smart home), and the like. The embodiments of the present application do not limit the application scenarios. Terminal equipment 10 may also sometimes be referred to as User Equipment (UE), access terminal equipment, UE unit, UE station, mobile station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication device, UE agent, UE device, or the like.

The communication system to which the above system architecture is applicable includes, but is not limited to, time division duplex-long Term Evolution (TDD multiplexing-L ong Term Evolution, TDD L TE), frequency division duplex-long Term Evolution (frequency division multiplexing-L ong Term Evolution, FDD L TE), long Term Evolution-enhanced (L ong Term Evolution-Advanced, L TE-a), and various wireless communication systems of future Evolution, such as 5G new air interface (NR) communication system.

With the development of wireless communication technology, more and more terminal devices are capable of supporting multi-antenna communication, as shown in fig. 1, a common multiple-input multiple-output (MIMO) communication system. Terminal device 10 has a plurality of antennas (antenna 101, antenna 102, antenna 103, and antenna 104), which may be used as an uplink port and a downlink port of terminal device 10 for transmitting data with network device 20. For convenience of description, in the embodiment of the present application, the uplink port 101U represents an antenna 101 in uplink transmission, the uplink port 102U represents an antenna 102 in uplink transmission, the uplink port 103U represents an antenna 103 in uplink transmission, and the uplink port 104U represents an antenna 104 in uplink transmission. Similarly, downlink port 101D represents antenna 101 in downlink transmission, downlink port 102D represents antenna 102 in downlink transmission, downlink port 103D represents antenna 103 in downlink transmission, and downlink port 104D represents antenna 104 in downlink transmission (not shown in fig. 1).

In general, the terminal device 10 may receive the downlink signal transmitted by the network device 20 through all the downlink ports together, so as to increase transmission reliability and increase downlink throughput. And transmit upstream signals to network device 20 through one or more upstream ports. As shown in fig. 1, in the process that the terminal device 10 sends an uplink signal to the network device 20, a signal sent by an uplink port, such as the uplink port 101U, may be received by multiple antennas of the network device 20 together, 1 data stream transmission may exist between the uplink port 101U and the network device, and if four uplink ports are used to send signals to the

network device

20, 4 data stream transmissions may be increased, and it is seen that, in an ideal situation, the more uplink ports that the terminal device 10 uses to send uplink signals to the network device 20, the more the uplink throughput of the terminal device 10 is increased.

Based on this, in one possible implementation manner, taking fig. 1 as an example, the network device 20 may allocate a 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 4 sub-signals corresponding to the uplink signal based on the MCS specified by the network device, or may consider that the uplink signal sent by the terminal device 10 to the network device 20 includes the 4 sub-signals. And the terminal device 10 allocates the same transmission power to the 4 uplink ports, and transmits the 4 sub signals through the 4 uplink ports, respectively. Assuming that the uplink signal includes a sub-signal 1U, a sub-signal 2U, a sub-signal 3U, and a sub-signal 4U, the terminal device may send the sub-signal 1U through the uplink port 101U, send the sub-signal 2U through the uplink port 102U, send the sub-signal 3U through the uplink port 103U, and send the sub-signal 4U through the uplink port 104U.

However, the communication channels between the upstream 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 a user often covers one or more antennas when holding the terminal device 10, so that the path loss of an uplink port corresponding to the covered antenna or antennas is greatly increased, and a test on a 1.8GHz frequency band shows that the uplink signal is attenuated by being held by hand by 7-8 dB. For example, the terminal device 10 in fig. 1 may be as shown in fig. 3, wherein the dotted lines represent perspective, that is, the antennas 101 to 104 are located on the back side of the terminal device 10, and the back side is in contact with the palm of the user when the terminal device 10 is held by the user. In fig. 3, antenna 103 and antenna 104 on the back of terminal device 10 are covered by the palm of the user, and antenna 101 and antenna 102 are not covered by the palm of the user, which causes the path loss corresponding to antenna 103 and antenna 104 to be much larger than the path loss corresponding to antenna 101 and antenna 102.

In addition, due to the limitation of the manufacturing process, the production cost, and other factors, the multiple antennas of the terminal device 10 may have different antenna gains, so that even if the same transmission power is allocated to different uplink ports, the actual power for transmitting the sub-signal between the different uplink ports may be different. Moreover, the patterns among the multiple antennas cannot be guaranteed to be identical, and even if the antenna calibration is completed in the initial direction, the antenna gains will be different in some other directions. In the embodiment of the present application, the difference in gain between different antennas, signal attenuation caused by hand-holding or shadowing can be regarded as the 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 sub-signals 1U to 4U also have different signal qualities on the network device 20 side. For example, when the terminal device transmits the sub signal 1U to the network device 20 through the upstream port 101U at a transmission power of 10w and transmits the sub signal 2U to the network device 20 through the upstream port 102U at a transmission power of 10w, since the path loss between the upstream port 101U and the network device 20 is larger than the path loss between the upstream port 102U and the network device 20, the reception power of the network device 20 for receiving the sub signal 1U is smaller than the reception power of the reception sub signal 2U. In practical use, the difference between the received powers of different sub-signals by the network device can even reach more than 10 dB.

In addition, the network device may adjust the MCS according to an initial block error rate (B L ER) of a Physical Uplink Shared Channel (PUSCH) and, when the B L ER exceeds/falls below a certain threshold, maintain the B L ER at a certain level, for example, 10%, thereby maintaining a high uplink throughput by lowering/increasing the MCS.

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 sub-signal transmitted by the terminal device 10 is smaller, the network device 20 cannot correctly decode the sub-signal, and thus the network device 20 cannot correctly decode the uplink signal to which the sub-signal belongs. Based on this, the network device 20 will generally allocate MCS to the terminal device 10 based on the transmission capability of the uplink port with the worst signal quality. For example, in the uplink ports 101U to 104U shown in fig. 1, the channel quality of 101U is the worst, and the network device 20 allocates MCS to the terminal device 10 based on the transmission capability of 101U to ensure that the sub-signals transmitted by the uplink ports 101U to 104U can be received.

By adopting the method, although the network device 20 can correctly decode the uplink signals sent by the terminal device 10 through the plurality of uplink ports, the method does not fully exert the transmission capability of the uplink port with better channel quality, and further improvement of the uplink throughput of the terminal device is limited. In addition, the method does not fully utilize the transmission power of the uplink port with better channel quality, which is not beneficial to reducing the power consumption of the terminal equipment.

Furthermore, there is another possible implementation. Terminal device 10 may select an uplink port with the best channel quality from the multiple uplink ports, and send an uplink signal to network device 20 through the uplink port with the best channel quality. Although the power consumption of the terminal device 10 can be reduced to a certain extent by using this method, this method does not actually use the characteristic of multiple antennas of the terminal device 10, and also limits further improvement of the uplink throughput of the terminal device 10.

As can be seen from the above two possible implementations, the terminal device 10 with multiple antennas cannot fully utilize the characteristics of multiple uplink ports to improve uplink throughput. Based on this, embodiments of the present application provide an uplink signal transmitting method and an uplink signal receiving method, which are collectively referred to as an uplink signal transmission method hereinafter, and allocate different transmission powers to a plurality of uplink ports of a terminal device 10, so that a plurality of sub-signals transmitted through the plurality of uplink ports can have the same or similar signal quality on the network device 20 side, thereby improving the uplink throughput of the terminal device 10 and reducing the power consumption of the terminal device 10.

Specifically, for an uplink port with better channel quality, the transmit power of the uplink port may be reduced, which is beneficial to reduce power consumption of the terminal device 10, and for an uplink port with worse channel quality, the transmit power of the uplink port may be increased, which is beneficial to improve the uplink throughput of the terminal device 10. Generally, the channel quality between the uplink port of the terminal device 10 and the network device 20 can be represented by a path loss, and the smaller the path loss, the better the channel quality, and the larger 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 transmitting the sub-signal is related to the path loss between the uplink port and the network device 20. The following is a detailed description of specific embodiments.

Fig. 4 is a schematic diagram of a possible uplink signal transmission flow provided in an embodiment of the present application, as shown in fig. 4, mainly including the following steps:

s201: the terminal equipment generates a first uplink signal, wherein the first uplink signal comprises N first sub-signals.

The first uplink signal may be a signal carried on a PUSCH channel, or may be a Sounding Reference Signal (SRS) for uplink beam management (beam management), codebook (codebook) and non-codebook (no codebook). That is, the technical solution provided in the embodiments of the present application may be used to allocate the transmission power of each uplink port when the terminal device transmits the signal of the PUSCH channel or the SRS.

In this embodiment, the terminal device may determine whether to use multiple uplink ports to transmit the first uplink signal according to an indication of the network device. If the network device indicates that the terminal device can use a plurality of uplink ports to send the first uplink signal, the first uplink signal generated by the terminal device includes N first sub-signals, where a value of N corresponds to the number of the used uplink ports. Taking fig. 1 as an example, if the network device 20 instructs the terminal device 10 to transmit the first uplink signal by using 4 uplink ports, the first uplink signal generated by the terminal device 10 includes 4 first sub-signals.

S202: the terminal equipment sends an ith first division signal to the network equipment through an ith uplink port in the N uplink ports, wherein the ith first sending power of the terminal equipment for sending the ith first division signal is related to the ith path loss between the ith uplink port and the network equipment; i is less than or equal to N, and N is a positive integer greater than 1.

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

In this embodiment, the terminal device may transmit N first sub signals of the first uplink signal from the N uplink ports respectively with the same or different transmission powers. Taking fig. 1 as an example, it is assumed that the first uplink signal includes a sub signal 1U, a sub signal 2U, a sub signal 3U, and a sub signal 4U, where the terminal device 10 transmits the sub signal 1U through the uplink port 101U and transmits the sub signal 2U through the 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 transmitting the sub-signal 1U may be the same as the transmission power of the sub-signal 2U; 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, the transmission power of the terminal device 10 for transmitting the sub-signal 1U may be different from the transmission power of the sub-signal 2U.

In a possible implementation manner, the ith first transmit power is positively correlated with the ith path loss estimate, and the ith path loss estimate is a path loss estimate between the ith 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 transmission power of the terminal device 10 for transmitting the sub-signal 1U is greater than the transmission power of the sub-signal 2U. By adopting the method, different transmission powers can be allocated to the uplink ports to compensate for the influence of the difference of the path loss between the

uplink ports

101U and 102U and the network device 20 on the receiving result of the network device 20, so that the receiving powers of the sub-signals 1U and 2U of the network device 20 are the same or similar. The uplink port 101U with large path loss can use larger transmission power, so as to adapt to the MCS with higher code rate, which is beneficial to improving the uplink throughput, and the transmission power of the uplink port 102U with small path loss can be saved, which is beneficial to reducing the power consumption of the terminal device 10 on the premise of not reducing the MCS code rate. Further, under the condition that part of the antennas are held by hands or shielded, the handheld terminal equipment adopting the scheme can reduce the attenuation influence of downlink receiving signals and uplink transmitting signals of the antennas. In S202, the ith first transmission power may be allocated by the terminal device itself, or may be allocated by the network device for the terminal device. Next, the first embodiment and the second embodiment are taken as examples to respectively provide possible implementation manners of the two cases.

Example one

Fig. 5 is a schematic diagram of a possible uplink signal transmission flow provided in an embodiment of the present application, and as shown in fig. 5, the method mainly includes the following steps:

s301: the terminal equipment generates a first uplink signal. The specific implementation manner of this step is similar to S201, and is not described again.

S302: the terminal acquires an ith path loss estimation value, wherein the ith path loss estimation value is the ith path loss estimation value. Taking fig. 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 transmit a first uplink signal, the terminal device 10 obtains estimated path loss values between the uplink ports 101U to 104U and the network device 20, respectively.

For an antenna of the terminal device 10, an uplink channel between an uplink port corresponding to the antenna and the network device 20 and a downlink channel between a downlink port corresponding to the antenna and the network device 20 have similar path losses, so in this embodiment of the present application, the terminal device 10 may estimate path losses between the 4 uplink ports and the network device 20 respectively according to a receiving condition of a downlink signal sent by the network device 20, thereby obtaining path loss estimated values corresponding to the N uplink ports respectively. Taking the uplink port 101U in fig. 1 as an example, in a possible implementation manner, the terminal device 10 may obtain a path loss estimation value between the uplink port 101U and the network device 20 according to the transmission power of the downlink signal sent by the network device 20 and the reception power of the downlink signal by the downlink port corresponding to the uplink port 101U, that is, the downlink port 101D.

S303: the terminal equipment distributes ith second sending power to the ith uplink port according to the ith path loss estimated value; wherein the ith second transmit power is positively correlated with the ith pathloss estimate. In this embodiment of the present application, the ith second transmission power refers to a second transmission power allocated by the terminal device to the ith uplink port.

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

Further, the terminal device 10 may transmit the sub-signals 1U to 4U, respectively, according to the second transmission powers allocated to the uplink ports 101U to 104U, respectively. In a possible implementation manner, as shown in S304 in fig. 5, before the terminal device 10 sends the ith first sub-signal, it may further determine whether the ith second transmission power is greater than the maximum transmission power of the ith uplink port; if yes, executing S305, and sending the ith sub-signal according to the maximum sending power, that is, the maximum sending power of the ith uplink port is the ith first sending power; if not, executing S306, and transmitting the ith sub-signal according to the ith second transmission power, namely the ith second transmission power is the ith first transmission power. By adopting the above method, the transmission power for transmitting the ith sub-signal in the terminal device 10 is not greater than the maximum transmission power of the ith uplink port.

In a possible implementation manner, a decibel power difference between an estimated received power corresponding to an ith second transmission power allocated to an ith uplink port and an estimated received power corresponding to a jth second transmission power allocated to a jth uplink port by a terminal device is not greater than a preset first threshold, wherein the estimated received power corresponding to the ith second transmission power is calculated according to an ith path loss estimation value, and the jth second transmission power is calculated according to a jth path loss estimation value; j is less than or equal to N and is not equal to i. The value of the first threshold may be set according to an environment of the communication system, and is usually smaller, that is, estimated received powers corresponding to second transmit powers respectively allocated to the N uplink ports by the terminal device are 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 powers.

In the 5GNR protocol, the network device may allocate total transmission power to the terminal device according to various factors such as the service type of the terminal device, the system environment, and the like, and indicate the total transmission power allocated to the terminal device through the first power information, as shown in S307 in fig. 5. In general, the first power information may be a Transmit Power Control (TPC) command, which is 2bits and may be used to indicate any one of 4 power adjustment amounts. The power adjustment amount is of two types, an accumulation type and an absolute value type. For the accumulated power adjustment amount, the terminal device needs to determine the total transmission power according to the power adjustment amount currently indicated by the network device and the sum of the previous power control adjustment amounts of the network device. For the absolute value type power adjustment amount, the terminal device may determine the total transmission power according to the power control adjustment amount currently indicated by the network device.

The TPC command may be carried in Downlink Control Information (DCI) on a Physical Downlink Control Channel (PDCCH), and the network device dynamically adjusts, through the TPC command, a total transmit power at which the terminal device transmits the first uplink signal.

In this embodiment of the present application, a TPC command for a network device to adjust PUSCH transmission power of a terminal device may be carried in DCI format 0_0 and DCI format 0_1 on a PDCCH, or may be carried in DCI format 2_2, that is, the network device carries TPC commands of a group of terminal devices through DCI format 2_2 to adjust total transmission power of the group of terminal devices. In addition, the TPC command for the network device to adjust the SRS power transmitted by the terminal device may be a TPC command for the network device to adjust the PUSCH channel power transmitted by the terminal device, that is, the network device jointly controls the power of the terminal device to transmit signals carried by the SRS and the PUSCH. The network device may also adjust the total transmission power of the terminal device for transmitting the SRS using the TPC command independent of the PUSCH, for example, the TPC command for the network device to adjust the total transmission power of the terminal device for transmitting the SRS may be carried in DCI format 2_3 on the PDCCH channel and transmitted to the terminal device.

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

wherein, P_PUSCH,b,f,c(i,j,q_dL) the total transmission power for transmitting the first uplink signal, which is allocated to the terminal equipment by the network equipment; p_CMAX,f,c(i) The maximum transmission power of the terminal equipment; p_{O_PUSCH,b,f,c}(j) Is a static operating point of the network equipment;

amount of influence of bandwidth of PUSCH on transmission power α_b,f,c(j) As a compensation factor for the path loss, P L_b,f,c(q_d) For the downlink path loss between the terminal equipment and the network equipment, for the terminal equipment with multiple antennas, P L_b,f,c(q_d) The minimum value of the downlink path loss between each of the plurality of downlink ports and the network device can be obtained; delta_TF,b,f,c(i) Is the amount of influence of the code rate on the transmission power; f. of_b,f,c(i, l) is the amount of power adjustment indicated by the network device through the TPC command.

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

wherein, P_SRS,b,f,c(i,q_sL) the total transmission power for transmitting the first uplink signal, which is allocated to the terminal equipment by the network equipment; p_{O_SRS,b,f,c}(q_s) Being network devicesA static operating point;

the amount of influence of the bandwidth of the SRS on the transmission power α_SRS,b,f,c(q_s) As a compensation factor for the path loss, P L_b,f,c(q_d) For the downlink path loss between the terminal equipment and the network equipment, for the terminal equipment with multiple antennas, P L_b,f,c(q_d) The minimum value of the downlink path loss between each of the plurality of downlink ports and the network device can be obtained; h is_b,f,c(i, l) is the amount of power adjustment indicated by the network device through the TPC command.

After the terminal equipment acquires the total transmission power allocated to the terminal equipment by the network equipment according to the first information, the terminal equipment can allocate corresponding second transmission power to the N uplink ports according to the path loss estimated values and the total transmission power between the N uplink ports and the network equipment respectively, so that the sum of the second transmission power of the N uplink ports is not greater than the total transmission power, and the total transmission power adjustment rule specified by a communication protocol is met.

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

Is P_i-1Linear power value of (d);

is the total transmission power P_SUMThe linear power value of (1) is the total decibel power value of the total transmission power, which is obtained by calculating according to the above formula one and formula two, so that the terminal equipment needs to obtain the decibel power value of the total transmission power according to the formula one or formula twoα is a path loss compensation factor, if the first uplink signal is a signal carried by a PUSCH channel, α is α above_b,f,c(j) If the first uplink signal is SRS, α is α_SRS,b,f,c(q_s)。

By the method provided in the first embodiment, the terminal device may estimate path losses between the N uplink ports and the network device, and allocate the transmit power to each uplink port based on the estimated path losses, so that the network device has the same or similar receive powers for the N sub-signals of the first uplink signal, which may increase the transmit power of the uplink port with larger path loss, thereby increasing uplink throughput, and may reduce the transmit power of the uplink port with smaller path loss, thereby reducing the power consumption of the terminal device without reducing MCS code rate.

Example two

Fig. 6 is a second schematic diagram of a possible uplink signal transmission flow provided by the embodiment of the present application, as shown in fig. 6, which mainly includes the following steps:

s401: and the network equipment allocates a corresponding decibel power difference value for the first uplink port according to the path loss corresponding to the first uplink port.

The decibel power difference corresponding to the first uplink port is used to indicate a 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 any one of the N uplink ports of the terminal device except the reference port. That is to say, the network device determines one uplink port from the N uplink ports of the terminal device as a reference port, and sequentially determines a decibel power difference between the third transmit power of the other uplink ports, except the reference port, of the N uplink ports with respect to the third transmit power of the reference port.

In this embodiment of the present application, the decibel power difference corresponding to the first uplink port is positively correlated to the path loss between the first uplink port and the network device, that is, the larger the path loss between the first uplink port and the network device is, the larger the decibel power difference allocated by the network device to the first uplink port is, and conversely, the smaller the path loss is, so that the larger transmission power is allocated to the uplink port with the larger path loss, and the smaller transmission power is allocated to the uplink port with the smaller path loss.

Taking fig. 1 as an example, assuming that 101U to 104U in the terminal device 10 are used to send a first uplink signal, and the network device determines that the uplink port 102U is a reference port, the network device 20 also allocates corresponding decibel power differences to the uplink port 101U, the uplink port 103U, and the uplink port 104U. The decibel power difference corresponding to the uplink port 101U is a 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 differences corresponding to the

uplink ports

103U and 104U are similar to the uplink port 101U, which is not described again.

In a possible implementation manner, the network device may obtain the path loss corresponding to the first uplink port according to the following manner, as shown in S407 in fig. 6, before allocating the corresponding decibel power difference to the first uplink port, the network device may further receive a second uplink signal sent by the terminal device. In this embodiment of the application, the second uplink signal includes M second sub-signals, and before the terminal device sends 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, respectively. And M is greater than or equal to N, and M uplink ports comprise N uplink ports.

In this embodiment, the network device may obtain, according to the second uplink signal, a path loss corresponding to the first uplink port. The path loss may be a path loss estimation value, or an equivalent path loss.

Specifically, in a possible implementation manner, after the network device receives the second uplink signal sent by the terminal device, the network device may obtain the transmission power of the second split signal of the second uplink signal sent by the terminal device through the first uplink port, and estimate the path loss corresponding to the first uplink port according to the transmission power of the second split signal sent by the terminal device through the first uplink port and the reception power of the second split signal, so as to obtain the estimated value of the path loss corresponding to the first uplink port.

For example, the network device may obtain the path loss estimation value corresponding to the first uplink port according to a rule shown in formula four:

PL_p＝P_p-P_p ⁰(formula four)

Wherein, P L_pIs the path loss estimation value, P, corresponding to the first uplink port_p ⁰For the received power, P, of the network device to the second partial signal transmitted via the first upstream port_pAnd transmitting the transmission power of the second sub-signal for the terminal equipment through the first uplink port.

Taking fig. 1 as an example, if the transmission power obtained by the network device 20 that the terminal device transmits the second split signal 1U through the uplink port 10 is 8dBm, and the reception power obtained by the network device that receives the second split signal 1U is 6dBm, the network device 20 may obtain a path loss estimation value corresponding to the uplink port 101U of 2 dB.

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

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

PL_p'＝P_p-R_p(formula five)

Wherein, P L_p' is the equivalent path loss, R, corresponding to the first uplink port_pThe signal-to-noise ratio of the second split signal received by the network device and transmitted through the first uplink port. It will be appreciated that the network device will inevitably also receive a certain noise signal when receiving the second component signal, whether the network device can correctly decode the second component signal, and also in relation to the signal strength of the noise signal received by the network device. In this applicationIn an embodiment, the snr of the second split signal received by the network device may be represented as a difference between decibel powers of the second split signal received by the network device and the noise signal, and the equivalent path loss may be obtained by combining the formula four, where the equivalent path loss is equal to a sum of the path loss and the decibel power of the noise signal.

In addition, the network device may further estimate path losses between the M second sub-signals and the M uplink ports, respectively, and determine an uplink port used for sending the first uplink signal in the terminal device according to the path losses between the M second sub-signals and the M uplink ports, respectively. Taking fig. 1 as an example, assuming that the terminal device 10 sends 4 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 network device 20 and the uplink port 103U is too large, the network device 20 determines that the uplink port 101U, the uplink port 102U, and the uplink port 104U are uplink ports for sending the first uplink signal next, and indicates the terminal device 10.

S402: the network equipment sends a reference port identifier of the reference port and second power information to the terminal equipment; and the second power information is used for indicating a decibel power difference value corresponding to the first uplink port.

In this embodiment of the application, the second power information may be issued through Radio Resource Control (RRC) signaling, MAC CE signaling, or DCI signaling, or may be issued together with the TPC command. In a possible implementation manner, if the difference between the second power information of the first uplink signal and the second power information of the second uplink signal is not large, the network device may not perform S402, and the terminal device may send the first uplink signal according to the second power information of the second uplink signal, thereby reducing an overhead of an air interface signaling.

The network equipment can acquire the accurate receiving condition of the second sub-signal, so that the precision of power control performed by the network equipment is higher; in addition, compared with the existing wireless communication protocol, the network device only needs to increase the signaling for sending the second power information, so that the modification of the existing air interface signaling is small.

S403: and the terminal equipment respectively acquires the third transmitting power of the N uplink ports according to the second power information. And the decibel power of the third transmitting power of the first uplink port is the sum of the decibel power difference value corresponding to the first uplink port and the decibel power of the third transmitting power of the reference port.

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

In one possible implementation, as shown in S402 in fig. 6, the network device may further transmit 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 may obtain the total transmission power according to the first power information, and specific implementation may refer to embodiment one, which is not described herein again.

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

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

wherein, P'_i-1In decibel power value for ith third transmission power, i ═ 1, N]；

Is P'_i-1Linear power value of P_aThird transmission power for reference port, P_n' is the third transmission power, Δ P L, of any one of the N uplink ports except the reference port_nIs the decibel power difference corresponding to the uplink port n.

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

wherein the first equation is used to indicate that the third transmit power of the reference port is an average value of the total transmit power in the N uplink ports. The terminal device may 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 powers of N-1 uplink ports, excluding the reference port, of the N uplink ports according to the second equation.

In another possible implementation manner, as shown in S402 in fig. 6, the network device may further 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 transmit power of the reference port according to the average value of the total transmit power allocated to the terminal device in the N uplink ports, and transmits the third power information to the terminal device.

And the terminal equipment receives the third power information and obtains a third sending power of the reference port according to the third power information. In this embodiment, the third power information is similar to the first power information, and may also be a power adjustment amount indicated by a TPC command, and the terminal device may obtain the third transmit power of the reference port based on a process similar to the above-mentioned obtaining of the total transmit power, which is not described again here.

The terminal device may then obtain, according to the third transmit power of the reference port and the second power information, third transmit powers of N-1 uplink ports, excluding the reference port, of the N uplink ports.

After the terminal device obtains the third transmit powers corresponding to the N uplink ports, in one possible implementation, the terminal device may send the N first sub-signals according to the third transmit powers, and in another possible implementation, as shown in S404 in fig. 6, the terminal device determines whether the ith third transmit power of the ith uplink port is greater than the maximum transmit power of the ith uplink port. If yes, executing S405, and sending the ith first sub-signal according to the maximum sending power of the ith uplink port; if not, S406 is executed to transmit the ith first sub-signal according to the ith third transmission power. So as to ensure that the power of the terminal device for transmitting the ith first sub-signal does not exceed the maximum transmission power of the ith uplink port.

In the two implementation manners for calculating the path loss provided in the embodiment of the present application, the network device may obtain the transmission power of the terminal device for transmitting the second sub-signal through the first uplink port in the following manners:

as shown in S407 in fig. 4, the terminal device may further transmit power headroom information indicating a Power Headroom (PH) of the terminal device to the network device. 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 this embodiment of the present application.

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

The network device may determine how much power remains of the transmission power of the current terminal device relative to the maximum transmission power of the terminal device according to the power margin reported by the terminal device, and may further determine the total actual transmission power of the terminal device for transmitting the second uplink signal.

Furthermore, the network device may obtain, according to the total actual transmission power, M fourth transmission powers at which the terminal device transmits M second sub-signals; wherein the sum of the M fourth transmission powers is the total actual transmission power. Specifically, the transmission power of the M second sub-signals transmitted by the terminal device is also controlled by the network device, as shown in S402 and S403, the network device may instruct the terminal device to transmit the transmission power of the N first sub-signals through the second power information, based on which, the network device may also obtain the second power information (hereinafter, referred to as the second power information of the second uplink signal) for instructing the transmission power of the M second sub-signals, and obtain the transmission power of the M second sub-signals transmitted by the terminal device by combining the total actual transmission power.

In both the first and second embodiments, the transmission power is respectively allocated 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 sub-signals of the first uplink signal. In addition, another uplink signal transmission method is provided in this embodiment of the present application, where the network device may adjust the transmission power of the terminal device for transmitting the N first sub-signals according to the signal quality of the N sub-signals of the received second uplink signal, for example, as shown in the next third embodiment.

EXAMPLE III

Fig. 7 is a third schematic diagram of a possible uplink signal transmission flow provided in the embodiment of the present application, as shown in fig. 7, which mainly includes the following steps:

s501: and the network equipment receives the second uplink signal sent by the terminal equipment. For specific implementation, refer to embodiment two, which is not described herein again.

S502: and the network equipment acquires the quality parameters corresponding to the N uplink ports respectively according to the N second sub-signals of the received second uplink signal. The ith quality parameter is a quality parameter of a second sub-signal received by the network device and sent by the terminal device through the ith uplink port.

In the embodiment of the present application, the quality parameter is a parameter indicating the quality of the signal. For example, the ith quality parameter may include a received power of a second sub-signal sent by the network device to the ith uplink port, or may include a signal-to-noise ratio of the second sub-signal sent by the terminal device through the ith uplink port, which is received by the network device. For convenience of description, the following description will take the received power as an example.

S503: and the network equipment allocates the ith power adjustment quantity to the ith uplink port according to the ith quality parameter.

It should be understood that the power adjustment amount in the embodiment of the present application may be a positive value, i.e., increasing the transmission power, or a negative value, i.e., decreasing the transmission power. In this embodiment, the ith power adjustment amount is inversely related to the signal quality of the second sub-signal received by the network device and transmitted by the ith uplink port. That is to say, the worse the signal quality of the second split signal received by the network device and sent by the ith uplink port is, the larger the ith power adjustment amount allocated by the network device to the ith uplink port is, and conversely, the better the signal quality of the second split signal received by the network device and sent by the ith uplink port is, the smaller the ith power adjustment amount allocated by the network device to the ith uplink port is.

The terminal device also transmits power headroom information to the network device, as shown at S501 in fig. 7. In the third embodiment, the power headroom information sent by the terminal device to the network device includes the power headroom of the ith uplink port. After receiving the power headroom information reported by the terminal device, the network device may allocate an ith power adjustment amount to the ith uplink port according to the ith quality parameter and the power headroom of the ith uplink port, where the ith power adjustment amount is not greater than the power headroom of the ith uplink port.

Specifically, the power headroom of the ith uplink port can be shown as the following equation eight:

PHⁱ＝P_i,CMAX-Pⁱ(formula eight)

Wherein the pH isⁱIs the power headroom of the ith uplink port, P_i,CMAXIs the maximum transmit power, P, of the ith uplink portⁱAnd transmitting the transmission power of the second sub-signal for the terminal equipment through the ith uplink port. PH when the second uplink signal is a signal carried by a PUSCH (physical uplink shared channel)ⁱIs type 1(type1), and when the second uplink signal is SRS, PH isⁱType 3(type 3).

Taking fig. 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 fig. 8a and fig. 8b, where fig. 8a is the power headroom information reported by the terminal device 10 when the second uplink signal is a signal carried by a PUSCH channel, and fig. 8b is the second uplink signalThe power headroom information reported by the terminal device 10 when the row signal is the SRS. Wherein R is a reserved field. As shown in fig. 8a and 8b, the power headroom information includes power headroom of each uplink port in the terminal device, and each power headroom occupies 6 bits. Such as PH in FIG. 8a¹ _type1To pH⁴ _type1And PH in FIG. 8b¹ _type3To pH⁴ _type3. In addition, as shown in fig. 8a and 8b, the power headroom information may further include maximum transmission powers of the uplink ports 101U to 104U, which are P respectively_1,CMAX、P_2,CMAX、P_3,CMAXAnd P_4,CMAX. In the power headroom information, the power headroom of the uplink ports are arranged according to a default order, for example, the power headroom is arranged according to the order of the port identifiers from small to large in fig. 8a and 8b, so that the network device can distinguish the uplink ports corresponding to different power headroom.

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 the power headroom information reported by the terminal device 10 when the second uplink signal is a signal carried by a PUSCH channel, and 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 fig. 8c and 8d, only the power headroom and the maximum transmission power of the reference port are reported, and the power headroom and the maximum transmission power of other uplink ports are reported in a differential manner. In FIG. 8c, the reference port is the upstream port 101U, and the differential PH is² _type3Indicates the power headroom of the upstream port 102U and the power headroom PH of the upstream port 101U¹ _type3Difference between, difference P_2,CMAXRepresents the maximum transmission power of the upstream port 102U and the maximum transmission power P of the upstream port 101U_1,CMAXThe difference between them. Other upstream ports are similar and will not be described again. The network device may obtain the power headroom and the maximum transmission power of other uplink ports on the basis of the power headroom and the maximum transmission power of the reference port. Comparing fig. 8a and fig. 8c, it can be seen that the occupied signaling resource can be shortened by adopting the differential mode.

In this embodiment, in the power headroom information reported by the terminal device, the reference port may be a 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 is the uplink port 101U, and then 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 reporting of the power headroom information may also only include the power headroom of the reference port, and the network device may obtain the PHs of other uplink ports 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 transmits the second sub-signal is 6dB, in the second power information of the second uplink signal, the reference port is still the uplink port 102U, the decibel power difference value corresponding to the uplink port 103U is 4dB, and the maximum transmission powers of the

uplink ports

102U and 103U are the same, it may be determined that the power headroom of the uplink port 103U is 6dB-4dB — 2 dB. 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 include only a minimum value of the power headroom of the N uplink ports, and the power adjustment amount allocated by the network device to the N uplink ports may not be greater than the minimum value. Therefore, the occupation of signaling resources can be reduced, and the power adjustment quantity allocated by the network equipment to the uplink port can be prevented from exceeding the power allowance of the uplink port.

S504: and the network equipment sends the fifth power information to the terminal equipment.

And the fifth power information is used for indicating power adjustment amounts allocated by the network device to the N uplink ports respectively. In this embodiment of the application, the fifth power information may be a TPC command, and the network device may extend the TPC command formats in the existing DCI0_ 0, DCI0_1, DCI 2_2, and DCI 2_3, or may define a new DCI format, where the new DCI format includes the TPC command allocated to each uplink port.

S505: and the terminal equipment receives fifth power information sent by the network equipment, acquires an ith power adjustment quantity distributed by the network equipment for the ith uplink port according to the fifth power information, and adjusts the ith sending power of the ith uplink port according to the ith power adjustment quantity.

In the embodiment of the present application, the terminal device may obtain the ith transmission power according to the rules shown in the formula one and the formula two. The difference from the acquisition of the total transmission power of the PUSCH is that P_CMAX,f,c(i) Becomes the maximum transmit power of the ith upstream port, P L_b,f,c(q_d) For the path loss between the ith upstream port and the network device, f_b,f,c(i, l) the power adjustment amount allocated to the ith uplink port by the network device. The difference between obtaining the total transmission power of the SRS is similar to the above difference, and is not described again.

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

Based on this, the network device may allocate a power adjustment amount in a unit of set 1, that is, allocate a power adjustment amount to set 1, where the power adjustment amount may be used as a power adjustment amount of the uplink port 101U and a power adjustment amount of the uplink port 102U in 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 for set 1. When executing S505, the terminal device may determine one or more uplink ports corresponding to the set identifier in the port set information, such as the uplink port 101U and the uplink port 102U described above. And adjusting the transmission power of the 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 power of the uplink port 101U and the uplink port 102U according to the power adjustment amount corresponding to the set 1.

By adopting the method, the uplink and downlink signaling overhead can be reduced when the uplink ports are more. For example, the terminal device 10 has 4 uplink ports, but the terminal device 10 as a smart phone has only two states, i.e., a covered state and an uncovered state, and the second threshold is set reasonably, so that the covered uplink ports can be divided into one group, the uncovered uplink ports can be divided into one group, and the two groups are respectively power controlled.

In this embodiment, the network device may send the port set information to the terminal device through a PDCCH channel, or may send the port set information to the terminal device through RRC signaling or MAC CE.

When port set information is transmitted through a PDCCH channel, the following DCI format may be adopted, or the following fields may be added to the existing DCI format:

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

when the port set information is sent through RRC signaling, the following information elements may be added in the RRC reconfiguration message:

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

the TPC-group is port set information, and the TPC-group includes nrOfTxPort elements, where nrOfTxPort represents the number of uplink ports used to transmit the first uplink signal, the corresponding uplink port identifier is 0 … nrOfTxPort-1, and in this embodiment, nrOfTxPort may take n.tpc-groupID as the port set identifier corresponding to the port identifier, and take 0 to maxnraftpcgroup-1, and maxnraftpcgroup represents the maximum port set number.

For example, assuming that the

uplink ports

101U and 102U belong to port set 1 and the

uplink ports

103U and 104U belong to port set 2, the TPC-group may be 0011, where "0" is the set identifier of port set 1 and "1" is the set identifier of port set 2. For another example, assuming that

upstream ports

101U, 102U, and 104U belong to set 1 and upstream port 103U belongs to set 2, TPC-group may be 0010.

When port set information is transmitted through a MAC CE, a new MAC CE may be set. A format form that the MAC CE can take is given below, taking nrOfTxPort equal to 4 and maxnraftpcgroup equal to 4 as an example. In FIG. 9, TPC-groupID_iA set identification representing the port set to which port i belongs. oct1 represents 1 bit of 8 bits. Taking the example that the

upstream ports

101U and 102U belong to set 1 and the

upstream ports

103U and 104U belong to set 2, TPC-groupID in fig. 9 is taken as an example₁And TPC-groupID₂Value 0 (port set identification of set 1), TPC-groupID₃And TPC-groupID₄The value is 1 (port set identification of set 2).

S506: the terminal equipment sends an ith first sub signal of the first uplink signal according to the adjusted ith sending power; the first uplink signal includes N first component signals. The specific examples are similar to the first and second embodiments, and are not described again.

By adopting the method provided by the third embodiment, the network device performs independent power control on different ports/port sets of the terminal device, so that the received power for receiving the N first sub-signals is balanced, thereby improving the uplink throughput and reducing the power consumption of the terminal device. In addition, the network equipment has complete information of the receiving condition of the second sub-signal, so that the power control precision of the network equipment is higher. Especially in the FDD frequency band, because the reciprocity of the uplink and the downlink is not ideal, the power control by the network equipment has more remarkable precision advantage.

The above-mentioned scheme provided by the present application is mainly introduced from the perspective of interaction between a network device and a terminal device. It is understood that, in order to implement the above functions, the network device or the terminal device may include a corresponding hardware structure and/or software module for performing each function.
