Description

Technical Field

[0001] This application relates to the field of wireless communication, and in particular, to a communication method and a communication device. Background Art

[0002] There are propagation losses in the process of wireless signal transmission, which affects the transmission performance of the signal. For example, high-frequency signals have relatively large transmission losses. Also, for example, there are relatively large transmission losses when a wireless signal is transmitted to a terminal at the edge of the network coverage. Again, for example, there are relatively large transmission losses when a wireless signal is transmitted from an outdoor environment to a terminal in an outdoor to indoor (O2I) scenario.

[0003] A power aggregation solution to solve the above problems is as follows: By adjusting the resource allocation of the wireless signal, temporarily aggregate the power on the component carriers (CCs) of other terminals to the CC of the target terminal, so as to reduce the impact of the propagation loss of the wireless signal, and thus improve the data transmission rate of the target terminal.

[0004] However, the improvement effect of the data transmission rate of this power aggregation solution is not good. Summary of the Invention

[0005] This application provides a communication method and a communication device, which can improve the improvement effect of the data transmission rate of the terminal in the power aggregation solution.

[0006] In a first aspect, this application provides a communication method, which is applied to a terminal, and the method includes: determining first information, where the first information is used to determine first power aggregation resources, and the first power aggregation resources are used to aggregate the power of a signal sent by a network device to the terminal, and the first power aggregation resources are partial frequency domain resources in the component carriers of the terminal; sending the first information to the network device.

[0007] As an example, this method can be executed by a terminal, or can be executed by a chip system, a hardware circuit, and / or a software module applied in the terminal.

[0008] As an example, the terminal can be a terminal whose network performance is less than a preset threshold. The network device can perform power aggregation on this terminal to improve the network performance of this terminal.

[0009] As an example, the network performance can be determined by the following performance metrics: downlink rate, reference signal receiving power (RSRP), and channel quality indicator (CQI). Among them, the situation where the network performance does not meet the preset threshold can include at least one of the following: the downlink rate is less than the rate threshold, the RSRP is less than the power threshold, and the value of the CQI is less than the channel quality threshold. Among them, the rate threshold, the power threshold, and the channel quality threshold can be set according to actual requirements and are not limited herein.

[0010] As an example, the first power aggregation resource can be the frequency domain resources that are idle in the component carrier (CC) of the terminal and whose channel quality meets the channel quality threshold. For example, the terminal can determine the first power aggregation resource based on the channel quality information of the received signal on the CC of the terminal. Among them, the terminal can report the channel quality information of the received signal on the CC of the terminal to the network device periodically or aperiodically.

[0011] In this technical solution, after determining the first power aggregation resource, the terminal can send the first information to the network device, so that the network device can determine the first power aggregation resource based on the first information and aggregate the power of the signal sent by the network device to the terminal into the first power aggregation resource, so that the terminal can receive the signal on the first power aggregation resource. Considering that the first power aggregation resource is the frequency domain resource that is idle in the CC of the terminal and whose channel quality meets the channel quality threshold, the power aggregation method provided by this technical solution improves the improvement effect of the data transmission rate of the terminal.

[0012] Combined with the first aspect, in some implementation manners of the first aspect, the first power aggregation resource is a partial frequency domain resource in the component carrier of the terminal, including: the first power aggregation resource is one or more resource units in the component carrier of the terminal, and the resource unit is a resource block, a resource block group, a resource element, a partial bandwidth BWP, a subband, or a resource element group.

[0013] As an example, the first power aggregation resource may be a part of the frequency domain resources in the CC of the terminal. For example, the first power aggregation resource may be one or more resource blocks (RBs) in the CC of the terminal, or may be one or more resource block groups (RBGs) in the CC of the terminal, or may be one or more resource elements (REs) in the CC of the terminal, or may be one or more resource element groups (REGs) in the CC of the terminal, or may be a part of the bandwidth part (BWP) in the CC of the terminal, or may be one or more subbands in the CC of the terminal. It should be noted that the resource unit may also be referred to as a frequency domain resource unit, a frequency domain resource, or others, and no specific limitation is made here.

[0014] In combination with the first aspect, in some implementations of the first aspect, the first information includes an index of the first power aggregation mode and / or a channel measurement result of the signal received on the first power aggregation resource, and the first power aggregation mode indicates the first power aggregation resource.

[0015] As an example, the first power aggregation resource may be indicated by the first power aggregation mode. For example, the first power aggregation mode may indicate the first power aggregation resource by indicating the position of the first power aggregation resource in the CC of the terminal, so as to indicate how to allocate the power of the signal sent by the network device to the terminal on the CC of the terminal.

[0016] As an example, the first power aggregation mode may be predefined by a protocol.

[0017] As an example, after determining the first power aggregation resource, the terminal may indicate the first power aggregation mode to the network device through the index of the first power aggregation mode, and further indicate the first power aggregation resource.

[0018] As an example, after determining the first power aggregation resource, the terminal may send a channel measurement result of the signal received on the first power aggregation resource to the network device, so that the network device can determine the first power aggregation resource based on the received channel measurement result.

[0019] In combination with the first aspect, in some implementations of the first aspect, the channel measurement result of the signal received on the first power aggregation resource meets a channel quality threshold.

[0020] As an example, the number of the first power aggregation resources may be one or more.

[0021] As an example, the terminal may send the first power aggregation resource whose channel measurement result meets the channel quality threshold to the network device.

[0022] In some embodiments, the terminal may send the first power aggregation resource with the optimal channel measurement result to the network device.

[0023] As an example, the channel measurement result may include one or more of the following: rank indication (RI), precoding matrix indicator (PMI), CQI, signal interference noise ratio (SINR), RSRP, reference signal received quality (RSRQ).

[0024] As an example, the optimal channel measurement result may be the highest CQI, or the higher SINR, or the best RSRQ.

[0025] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving second information from the network device, where the second information is used to configure the first power aggregation mode.

[0026] As an example, the first power aggregation mode may be configured by the network device. For example, the network device may configure the first power aggregation mode by sending second information to the terminal, and the second information may indicate the parameters of the first power aggregation mode. Correspondingly, the terminal may receive the second information.

[0027] In combination with the first aspect, in some implementations of the first aspect, the second information includes the index of the first power aggregation mode and / or the granularity of the resource units of the first power aggregation resource.

[0028] As an example, the index of the first power aggregation mode is, for example, 1, 2, ……, K, where K is a positive integer.

[0029] As an example, the granularity of the resource units of the first power aggregation resource can be understood as the number of resource units included in the first power aggregation resource. For example, the number of RBs included in the first power aggregation resource.

[0030] In combination with the first aspect, in some implementations of the first aspect, the first power aggregation resource includes: all resource units on the first half bandwidth of the component carrier, all resource units on the second half bandwidth of the component carrier, odd resource units on the entire bandwidth of the component carrier, or even resource units on the entire bandwidth of the component carrier.

[0031] As an example, the first power aggregation resource may include all resource units in the first half of the bandwidth of the terminal's component carrier (CC), or may include all resource units in the first half of the bandwidth of the terminal's CC, or may include odd resource units in the entire bandwidth of the terminal's CC, or may include even resource units in the entire bandwidth of the terminal's CC.

[0032] In combination with the first aspect, in some implementations of the first aspect, the second information includes indication information of the maximum over-transmission power and / or indication information of the position of the first power aggregation resource in the component carrier.

[0033] As an example, when the adjacent channel leakage ratio (ACLR) requirement or the out-of-band leakage standard is met, over-transmission (over-issue) of the signal power is allowed. For example, when the first power aggregation resource does not include frequency domain resources at the edge position of the operating frequency band of the network device, or when the frequency domain resources adjacent to the first power aggregation resource still belong to the frequency domain resources of the network device, the network device is allowed to over-transmit the signal power. Among them, the edge position of the operating frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the operating frequency band of the network device. The starting frequency domain position can be understood as the frequency domain position with a first preset offset from the starting frequency point of the operating frequency band, and the ending frequency domain position can be understood as the frequency domain position with a second preset offset from the ending frequency point of the operating frequency band. The first preset offset and the second preset offset can be set according to actual requirements or obtained through signaling, and this application does not make specific limitations in this regard. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the operating frequency band of the network device. The over-transmission of the signal power can be understood as the power of the signal sent by the network device to the terminal being greater than the rated power of the signal. Therefore, the second information may further include the maximum over-transmission power. It should be noted that due to different capabilities of the terminal, the number of CCs that the terminal can use can be one or more, that is, the number of CCs of the terminal can be one or more.

[0034] As an example, the second information may further include indication information about the position of the first power aggregation resource in the CC of the terminal. For example, the indication information about the position of the first power aggregation resource in the CC of the terminal may indicate the starting position of the first power aggregation resource in the CC of the terminal, or which resource element in the CC of the terminal is the starting position of the first power aggregation resource, or which resource element in the CC of the terminal is the starting resource element included in the first power aggregation resource. Therefore, the terminal can determine the starting position of the first power aggregation resource in the CC of the terminal based on the indication information about the position of the first power aggregation resource in the CC of the terminal, and determine the number of resource elements included in the first power aggregation resource based on the granularity of the resource elements of the first power aggregation resource, so as to determine the position distribution of all the resource elements included in the first power aggregation resource in the CC of the terminal. Another example is that the indication information about the position of the first power aggregation resource in the CC of the terminal may indicate the positions of all the resource elements included in the first power aggregation resource in the CC of the terminal.

[0035] In this implementation manner, over-transmission of signal power is allowed, which can further improve the data transmission rate of the terminal.

[0036] Combined with the first aspect, in some implementation manners of the first aspect, the second information is further used to configure the measurement manner and / or reporting manner of the channel measurement result.

[0037] As an example, the second information may include measurement configuration information. For example, the second information may include measurement reporting configuration and / or measurement resource configuration.

[0038] In this implementation manner, after receiving the second information, the terminal can determine what resources to measure based on the measurement resource configuration, and determine how to measure and report through the measurement reporting configuration, so as to measure the channel quality of the signal received on the first power aggregation resource and report it to the network device.

[0039] Combined with the first aspect, in some implementation manners of the first aspect, the method further includes: sending third information to the network device, where the third information is used to request power aggregation.

[0040] As an example, when the downlink transmission rate of the terminal or the channel quality cannot meet the service quality requirements, the third information may be sent to the network device to request the network device to initiate power aggregation, so as to improve the downlink transmission rate or channel quality of the terminal.

[0041] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: sending fourth information to the network device, where the fourth information indicates the power aggregation mode supported by the terminal.

[0042] As an example, the power aggregation mode supported by the terminal can be a power aggregation mode determined by the terminal itself.

[0043] As an example, the fourth information may further include the cell(s) for which measurement is requested and / or the beam(s) for which measurement is requested, so that the network device can configure the measurement method and / or reporting method of the channel measurement result based on the fourth information.

[0044] As an example, the third information and the fourth information can be carried and sent in the same message, or can be carried and sent in different messages, which is not limited herein. [[ID=II]]

[0045] In a second aspect, the present application provides a communication method, which is applied to a network device. The method includes: receiving first information from a terminal, where the first information is used to determine a first power aggregation resource, and the first power aggregation resource is used to aggregate the power of the signal sent by the network device to the terminal, and the first power aggregation resource is a partial frequency domain resource in the component carrier of the terminal; and sending a signal to the terminal based on the first information.

[0046] As an example, this method can be executed by the network device, or can be executed by a chip system, a hardware circuit, and / or a software module applied in the network device.

[0047] As an example, the terminal can be a terminal whose network performance is less than a preset threshold. The network device can perform power aggregation on this terminal to improve the network performance of this terminal.

[0048] As an example, the network performance can be determined by the following performance metrics: downlink rate, RSRP, and CQI. Among them, the network performance not meeting the preset threshold may include at least one of the following: the downlink rate is less than the rate threshold, the RSRP is less than the power threshold, and the value of CQI is less than the channel quality threshold. Among them, the rate threshold, the power threshold, and the channel quality threshold can be set according to actual requirements and are not limited herein.

[0049] As an example, the first power aggregation resource can be a frequency domain resource that is idle in the CC of the terminal and whose channel quality meets the channel quality threshold. For example, the terminal can determine the first power aggregation resource based on the channel quality information of the signal received on the CC of the terminal. Among them, the terminal can report the channel quality information of the signal received on the CC of the terminal to the network device periodically or aperiodically.

[0050] In this technical solution, the network device can receive the first information sent by the terminal, and after determining the first power aggregation resource based on the first information, converge the power of the signal sent by the network device to the first power aggregation resource, so that the terminal can receive the signal on the first power aggregation resource. Considering that the first power aggregation resource is the frequency domain resource that is idle in the CC of the terminal and the channel quality meets the channel quality threshold, the power aggregation method provided by this technical solution improves the data transmission rate of the terminal.

[0051] Combined with the second aspect, in some implementation manners of the second aspect, the first power aggregation resource is a partial frequency domain resource in the component carrier of the terminal, including: the first power aggregation resource is one or more resource units in the component carrier of the terminal, and the resource unit is a resource block, a resource block group, a resource element, a partial bandwidth BWP, a sub-band or a resource element group.

[0052] As an example, the first power aggregation resource can be a partial frequency domain resource in the CC of the terminal. For example, the first power aggregation resource can be one or more RBs in the CC of the terminal, or can be one or more RBGs in the CC of the terminal, or can be one or more REs in the CC of the terminal, or can be one or more REGs in the CC of the terminal, or can be the BWP in the CC of the terminal, or can be one or more sub-bands in the CC of the terminal. It should be noted that the resource unit can also be referred to as a frequency domain resource unit, a frequency domain resource or others, and no specific limitation is made here.

[0053] Combined with the second aspect, in some implementation manners of the second aspect, the first information includes an index of the first power aggregation mode and / or a channel measurement result of receiving a signal on the first power aggregation resource, and the first power aggregation mode indicates the first power aggregation resource.

[0054] As an example, the first power aggregation resource can be indicated by the first power aggregation mode. For example, the first power aggregation mode can indicate the first power aggregation resource by indicating the position of the first power aggregation resource in the CC of the terminal, so as to indicate how to allocate the power of the signal sent by the network device to the terminal on the CC of the terminal.

[0055] As an example, the first power aggregation mode can be predefined by a protocol.

[0056] As an example, after determining the first power aggregation resource, the terminal can indicate the first power aggregation mode to the network device through the index of the first power aggregation mode, and further indicate the first power aggregation resource.

[0057] As an example, after determining the first power aggregation resource, the terminal may send the channel measurement result of the received signal on the first power aggregation resource to the network device; correspondingly, the network device may receive the channel measurement result sent by the terminal and determine the first power aggregation resource based on the received channel measurement result.

[0058] Combined with the second aspect, in some implementation manners of the second aspect, the channel measurement result of the received signal on the first power aggregation resource meets the channel quality threshold.

[0059] As an example, the number of the first power aggregation resources may be one or more.

[0060] As an example, the terminal may send the first power aggregation resource whose channel measurement result meets the channel quality threshold to the network device.

[0061] In some embodiments, the terminal may send the first power aggregation resource with the optimal channel measurement result to the network device.

[0062] As an example, the channel measurement result may include one or more of the following: RI, PMI, CQI, SINR, RSRP, RSRQ.

[0063] As an example, the optimal channel measurement result may be the highest CQI, or the higher SINR, or the best RSRQ.

[0064] Combined with the second aspect, in some implementation manners of the second aspect, the method further includes: sending second information to the terminal, where the second information is used to configure the first power aggregation mode.

[0065] As an example, the first power aggregation mode may be configured by the network device. For example, the network device may configure the first power aggregation mode by sending second information to the terminal, and the second information may indicate the parameters of the first power aggregation mode.

[0066] As an example, the network device may configure the first power aggregation mode for the terminal according to the real-time resource idle situation in the CC of the terminal.

[0067] Combined with the second aspect, in some implementation manners of the second aspect, the second information includes the index of the first power aggregation mode and / or the granularity of the resource unit of the first power aggregation resource.

[0068] As an example, the index of the first power aggregation mode is, for example, 1, 2, ……, K, where K is a positive integer.

[0069] As an example, the granularity of the resource unit of the first power aggregation resource can be understood as the number of resource units included in the first power aggregation resource. For example, the number of RBs included in the first power aggregation resource.

[0070] In combination with the second aspect, in some implementations of the second aspect, the first power aggregation resource includes: all resource units on the first half bandwidth of the component carrier, all resource units on the second half bandwidth of the component carrier, odd resource units on the entire bandwidth of the component carrier, or even resource units on the entire bandwidth of the component carrier.

[0071] As an example, the first power aggregation resource may include all resource units on the first half bandwidth in the CC of the terminal, or may include all resource units on the first half bandwidth in the CC of the terminal, or may include odd resource units on the entire bandwidth of the CC of the terminal, or may include even resource units on the entire bandwidth of the CC of the terminal.

[0072] In combination with the second aspect, in some implementations of the second aspect, the second information includes indication information of the maximum over-transmission power and / or indication information of the position of the first power aggregation resource in the component carrier.

[0073] As an example, when the ACLR requirement or out-of-band leakage standard is met, over-transmission (over-issue) of the signal power is allowed. For example, when the first power aggregation resource does not include frequency domain resources at the edge position of the operating frequency band of the network device, or when the frequency domain resources adjacent to the first power aggregation resource still belong to the frequency domain resources of the network device, the network device is allowed to over-issue the signal power. Among them, the edge position of the operating frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the operating frequency band of the network device. The starting frequency domain position can be understood as the frequency domain position with a first preset offset from the starting frequency point of the operating frequency band, and the ending frequency domain position can be understood as the frequency domain position with a second preset offset from the ending frequency point of the operating frequency band. The first preset offset and the second preset offset can be set according to actual needs or obtained through signaling, and the present application does not make specific limitations in this regard. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the operating frequency band of the network device. The over-issue of the signal power can be understood as the power of the signal sent by the network device to the terminal being greater than the rated power of the signal. Therefore, the second information may also include the maximum over-transmission power. It should be noted that due to different capabilities of the terminal, the number of CCs available to the terminal can be one or more, that is, the number of CCs of the terminal can be one or more.

[0074] As an example, the second information may further include indication information about the position of the first power aggregation resource in the CC of the terminal. For example, the indication information about the position of the first power aggregation resource in the CC of the terminal may indicate the starting position of the first power aggregation resource in the CC of the terminal, or which resource element in the CC of the terminal is the starting position of the first power aggregation resource, or which resource element in the CC of the terminal is the starting resource element included in the first power aggregation resource. Therefore, the terminal may determine the starting position of the first power aggregation resource in the CC of the terminal based on the indication information about the position of the first power aggregation resource in the CC of the terminal, and determine the number of resource elements included in the first power aggregation resource based on the granularity of the resource elements of the first power aggregation resource, so as to determine the position distribution of all the resource elements included in the first power aggregation resource in the CC of the terminal. For another example, the indication information about the position of the first power aggregation resource in the CC of the terminal may indicate the positions of all the resource elements included in the first power aggregation resource in the CC of the terminal.

[0075] In this implementation manner, overtransmission of signal power is allowed, which can further improve the data transmission rate of the terminal.

[0076] Combined with the second aspect, in some implementation manners of the second aspect, the second information is further used to configure the measurement manner and / or reporting manner of the channel measurement result.

[0077] As an example, the second information may include measurement configuration information. For example, the second information includes measurement reporting configuration and / or measurement resource configuration.

[0078] In this implementation manner, the network device may configure measurement configuration information for the terminal through the second information, so that after receiving the second information, the terminal may determine what resources to measure based on the measurement resource configuration, and determine how to measure and report through the measurement reporting configuration, so as to measure the channel quality of the signal received on the first power aggregation resource and report it to the network device.

[0079] Combined with the second aspect, in some implementation manners of the second aspect, the method further includes: receiving third information from the terminal, where the third information is used to request power aggregation.

[0080] As an example, when the downlink transmission rate of the terminal or the channel quality cannot meet the service quality requirements, the terminal may send third information to the network device to request the network device to initiate power aggregation, so as to improve the downlink transmission rate or channel quality of the terminal. Correspondingly, the network device may receive the third information and send power aggregation.

[0081] In combination with the second aspect, in some implementations of the second aspect, the method further includes: sending fourth information to the network device, where the fourth information indicates the power aggregation mode supported by the terminal.

[0082] As an example, the power aggregation mode supported by the terminal may be a power aggregation mode determined by the terminal independently. Among them, after receiving the fourth information, the network device may determine the second information based on the fourth information.

[0083] As an example, the fourth information may further include the cell for which measurement is requested and / or the beam for which measurement is requested, so that the network device can configure the measurement method and / or reporting method of the channel measurement result for the terminal based on the fourth information.

[0084] As an example, the third information and the fourth information may be carried and sent in the same message, or may be carried and sent in different messages, which is not limited herein.

[0131] In the embodiments of the present application, a network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices.

[0132] In the embodiments of this application, the terminal device may be referred to as a terminal, which is an entity on the user side for receiving or sending signals. The terminal may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem that have wireless communication capabilities.

[0133] The network device may provide services for terminals within a cell. The terminal communicates with the network device corresponding to the cell or other devices through the transmission resources allocated by the network device (for example, frequency domain resources, or in other words, spectrum resources). The network device may be a macro base station (such as a macro eNB or a macro gNB, etc.), or may also be a base station corresponding to a small cell. Here, the small cell may include: a metro cell, a micro cell, a pico cell, a femto cell, etc. These small cells have the characteristics of a small coverage area and a low transmission power, and are suitable for providing high-rate data transmission services.

[0134] Exemplarily, Figure 1 is a schematic diagram of a communication system applicable to the embodiments of this application. As Figure 1 shown, the communication system may include multiple network devices (such as Figure 1 the base station 110, the base station 120, and the base station 130 in Figure 1 ), and a terminal 140. Among them, the number of network devices and terminals is only an example, and this application does not limit this. It should be understood that Figure 1 is only a schematic diagram, and other network devices may also be included in this communication system. For example, core network devices may also be included, which are not drawn in Figure 1 .

[0135] Taking the base station 110 among multiple network devices as an example, the base station 110 can provide communication services for the terminals 140 within a cell. The base station 110 can send downlink information to the terminals 140, and the downlink information can be control information or data information, which is not limited in this application. The terminals 140 can send uplink information to the base station 110. In some embodiments, multiple network devices can simultaneously transmit data or control signaling to the terminals 140.

[0136] Exemplarily, Figure 2 is a schematic illustration diagram of another communication system applicable to the embodiments of this application. As Figure 2 shown, this communication system may include a terminal 210 and a network device 220. Among them, the terminal 210 includes a processor 211, a memory 212, and a transceiver 213.

The network device 220 includes a processor 221, a memory 222, and a transceiver 223. The transceiver 223 includes a transmitter 2231, a receiver 2232, and an antenna 2233. The memory 222 is used to store computer program code, and the processor 221 can call the computer program code to enable the network device 220 to implement related functions. The receiver 2132 can be used to receive transmission control information sent by the network device 220 through the antenna 2133, and the transmitter 2131 can be used to send transmission feedback information to the network device 220 through the antenna 2133. The transmitter 2231 can be used to send transmission control information to the terminal 210 through the antenna 2233, and the receiver 2232 can be used to receive transmission feedback information sent by the terminal 210 through the antenna 2233.

[0137] The following will describe Figure 3 the technical problems solved by this application.

[0138] Wireless signals incur propagation losses during transmission, which affects the signal transmission performance. For example, high-frequency signals have significant transmission losses due to factors such as free-space loss and atmospheric absorption during transmission. Free-space loss can be understood as the basic loss when high-frequency signals propagate in free space, and free-space loss is proportional to the square of the frequency. Atmospheric absorption can be understood as the absorption of high-frequency signals by molecules (such as water vapor) in the atmosphere during propagation, and atmospheric absorption intensifies with the increase in frequency. Another example is that terminals at the edge of the network coverage are far from the network device, resulting in significant transmission losses when wireless signals are transmitted to terminals at the edge of the network coverage. Additionally, there are significant transmission losses when wireless signals are transmitted from the outdoor environment to terminals in the outdoor to indoor (O2I) scenario. It should be noted that O2I is used to describe the process of signal transmission from the outdoor environment to the indoor environment. In the O2I scenario, the signal must pass through the exterior walls, windows, and other possible obstacles of the building to reach the indoor receiver (such as a terminal).

[0139] A power aggregation scheme to solve the above problems is as follows: By adjusting the resource allocation of wireless signals, temporarily aggregate the power on the component carriers (CCs) of other terminals to the CC of the target terminal to enhance the signal reception quality of the target terminal, thereby reducing the impact of wireless signal propagation losses and further improving the data transmission rate of the target terminal. Among them, the target terminal can include terminals at the edge of the network coverage, indoor and outdoor (O2I) terminals, and terminals with a download rate less than or equal to the download threshold (such as 100 megabits per second (Mbps)). In the embodiments of the present application, power aggregation can be used to describe a resource allocation strategy in a wireless communication network. Power aggregation can also be referred to as power concentration, power reunion, or power enhancement, and the present application does not make specific limitations on this. Through power aggregation, the data transmission rate and service experience of the target terminal can be improved without significantly increasing the total network power consumption. The component carrier can also be called the carrier component. The data transmission rate can also be called the data rate, which represents the amount of information (such as the number of bits) transmitted on the channel per unit time. It should be understood that the CC of the terminal can be understood as the frequency domain resources allocated by the network device for the terminal when providing network services for the terminal.

[0140] Exemplarily, Figure 3 is a schematic flowchart of a power aggregation method. As Figure 3 shown, the method may include S301 to S305.

[0141] S301, determine the target terminal.

[0142] As an example, the target terminal can be understood as a terminal whose network performance does not meet the preset threshold.

[0143] As an example, network performance can be determined by the following performance metrics: downlink rate, reference signal receiving power (RSRP), and channel quality indicator (CQI).

[0144] As an example, the network performance not meeting the preset threshold may include at least one of the following: the downlink rate is less than the rate threshold, the RSRP is less than the power threshold, and the value of CQI is less than the channel quality threshold. Herein, the rate threshold, the power threshold, and the channel quality threshold can be set according to actual requirements and are not limited herein.

[0145] As an example, the terminal can report the network performance of the terminal to the network device, so that the network device can monitor the network performance of the terminals in the cell, thereby determining the target terminal.

[0146] S302, determine the first CC.

[0147] As an example, the network device can configure a CC for each terminal in the cell, so that the terminal can receive signals on the CC.

[0148] As an example, the first CC can be understood as a CC with a power utilization rate less than the utilization rate threshold. It should be noted that the power of the CC can be understood as the power allocated by the network device to the CC, or the power of the signal sent by the network device to the terminal on the CC.

[0149] As an example, the network device can judge or evaluate the power usage of the CCs of all terminals in the cell, and determine the CC with a power utilization rate less than the utilization rate threshold as the first CC. It should be understood that the number of the first CCs can be one or more.

[0150] S303, perform power aggregation.

[0151] As an example, after determining the first CC, the network device can temporarily aggregate or allocate the power on the first CC to the CC of the target terminal. For example, the network device can temporarily stop allocating power to the first CC, and aggregate and concentrate the part of the power not allocated to the first CC on the CC of the target terminal, so as to increase the power of the signal sent by the network device to the target terminal, thereby increasing the data transmission rate of the target terminal.

[0152] In addition, after the network device implements power aggregation, it can monitor the RSRP and signal interference noise ratio (SINR) of the target terminal to determine whether the signal quality of the target terminal has been improved. If the signal quality of the target terminal remains unchanged, or the difference between the signal quality of the target terminal after power aggregation and the signal quality of the target terminal before power aggregation is less than the signal quality threshold, it is considered that the signal quality of the target terminal has not been improved; if the difference between the signal quality of the target terminal after power aggregation and the signal quality of the target terminal before power aggregation is greater than or equal to the signal quality threshold, it is considered that the signal quality of the target terminal has been improved.

[0153] Among them, when the signal quality of the target terminal has not been improved, S302 to S303 can be repeatedly executed until the signal quality of the target terminal is improved.

[0154] S304, upgrade the modulation and coding scheme level of the target terminal.

[0155] As an example, after the signal quality of the target terminal is improved, the network device needs to correspondingly upgrade the level of the modulation and coding scheme (MCS) of the target terminal, so that the MCS level can adapt to the change of signal quality, increase the data rate and network throughput of the target terminal, and ensure the reliability of data transmission. It should be noted that the higher the SINR of the terminal, the better the signal quality, and the higher the CQI of the terminal, the higher the MCS level of the terminal should be.

[0156] S305, monitor and optimize the power aggregation scheme.

[0157] As an example, the network device can continuously monitor or monitor the network performance of the target terminal to ensure that the power aggregation strategy can effectively improve the signal quality and service quality of the target terminal. If the improvement effect of the signal quality, service quality or network performance of the target terminal does not reach the preset threshold, S302 to S304 can be repeatedly executed to re-evaluate the first CC, adjust the power aggregation strategy and the selection and configuration of MCS.

[0158] In some embodiments, the terminals in the cell can periodically feedback the network performance of the terminals to the network device, so that the network device can maintain sensitivity to changes in network load and terminal distribution based on the network performance feedback by the terminals in the cell, so as to facilitate the network device to adjust the power aggregation strategy and optimize the MCS configuration.

[0159] Figure 3The method in [reference] enables a network device (such as a base station) to reallocate power to the CC of a target terminal without increasing the total RF power, thereby increasing the power on the CC of the target terminal and improving the communication quality and data rate of the target terminal.

[0160] However, Figure 3 The power aggregation method in [reference] has certain limitations in power allocation and frequency-domain resource utilization, resulting in poor improvement in the data transmission rate of the target terminal. For example, Figure 3 The power aggregation method in [reference] sets that the target terminal can use all available frequency-domain resources in the target CC. Therefore, the network device aggregates power for all available frequency-domain resources in the target CC, or in other words, the network device aggregates / distributes power to all available frequency-domain resources in the target CC. However, the frequency-domain resources that the target terminal can use are related to the capabilities of the target terminal. Therefore, the target terminal may not be able to use all available frequency-domain resources in the target CC, resulting in the power aggregated to the target CC not being fully utilized and thus unable to fully improve the data rate of the target terminal. Additionally, Figure 3 The power aggregation method in [reference] does not consider that different frequency-domain resources may have different channel qualities and ignores the importance of channel quality for improving the data rate of the target terminal, thus unable to fully improve the data rate of the target terminal. The target CC can be understood as the CC of the target terminal.

[0161] Based on this, the applicant proposes that the first power can be aggregated to the frequency-domain resources that are idle and have channel quality meeting the channel quality threshold in the first frequency-domain resources, thereby optimizing the existing power aggregation method or power aggregation strategy, effectively enhancing the signal quality of the target terminal, and further improving the service experience of the target terminal. The first frequency-domain resources can be understood as the frequency-domain resources that the target terminal can use in the target CC.

[0162] In view of this, the present application provides a communication method and a communication device. In the technical solution provided by the present application, the network device can determine the frequency-domain resources for power aggregation in the target CC through the measurement feedback of the terminal, or in other words, determine to which frequency-domain resources in the target CC the power is to be aggregated, thereby effectively improving the signal quality of the target terminal and further improving the service experience of the target terminal.

[0163] Next, in combination with Figures 4 to 7 , the technical solution provided by the present application will be described in detail.

[0164] Figure 4 It is a schematic diagram of a communication method provided in an embodiment of the present application. As Figure 4 shown, the method may include S401 and S402.

[0165] As an example, this method can be executed by a terminal, or by a chip system, a hardware circuit, and / or a software module applied to the terminal. It should be understood that the terminal in this embodiment can be understood as a terminal with network performance not meeting a preset threshold. The network device can perform power concentration on the terminal to improve the network performance of the terminal.

[0166] S401, determine first information, where the first information is used to determine a first power concentration resource, and the first power concentration resource is used to concentrate the power of the signal sent by the network device to the terminal. The first power concentration resource is a part of the frequency domain resources in the CC of the terminal.

[0167] As an example, the first power concentration resource can be a part of the frequency domain resources in the CC of the terminal. For example, the first power concentration resource can be one or more resource units in the CC of the terminal. The resource unit can be a resource block (RB), a resource block group (RBG), a resource element (RE), a bandwidth part (BWP), a sub-band, or a resource element group (REG). In some embodiments, the resource unit can also be referred to as a frequency domain resource, or a frequency domain resource unit, which is not limited herein.

[0168] As an example, the first power concentration resource can be the frequency domain resources that are idle in the CC of the terminal and whose channel quality meets a channel quality threshold. The channel quality threshold can be set according to actual needs, and this application does not limit it.

[0169] As an example, the terminal can determine the first power concentration resource based on the channel quality information of the signal received on the CC of the terminal. It should be noted that the terminal can report the channel quality information of the signal received on the CC of the terminal to the network device periodically or aperiodically. For example, the terminal can determine the frequency domain resources that are idle in the CC of the terminal and whose channel quality meets the channel quality threshold based on the most recently reported channel quality information, and determine the frequency domain resources that are idle in the CC of the terminal and whose channel quality meets the channel quality threshold as the first power concentration resource. Herein, the most recently reported can be understood as the most recent report from the reporting time to the current time. For another example, the terminal can determine the frequency domain resources that are idle in the CC of the terminal and whose channel quality meets the channel quality threshold based on the channel quality information reported multiple times recently, so as to determine the first power concentration resource. The channel quality information can include CQI.

[0170] As an example, the network device can concentrate the power of the signal sent by the network device to the terminal on the first power concentration resource. Among them, the power of the signal sent by the network device to the terminal can be the power on the target CC after power concentration is performed.

[0171] As an example, the first information may include indication information of a first power aggregation resource, so that the network device can determine the first power aggregation resource based on the first information.

[0172] S402, send the first information to the network device.

[0173] In this embodiment, after determining the first power aggregation resource, the terminal may send the first information to the network device. Correspondingly, the network device may receive the first information and determine the first power aggregation resource based on the first information and the capabilities of the terminal.

[0174] As an example, after determining the first power aggregation resource, the network device may configure downlink transmission information for the terminal based on the first power aggregation resource and send the configuration information to the terminal.

[0175] As an example, the network device may send the configuration information to the terminal through a physical downlink control channel (PDCCH). In some embodiments, the configuration information may include information such as resource allocation, power control, modulation mode, and data rate.

[0176] In some embodiments, the number of first power aggregation resources reported by the terminal may be multiple, and the network device may determine the final first power aggregation resource from the multiple first power aggregation resources based on factors such as the capabilities of the terminal and the channel quality information reported by the terminal.

[0177] In this embodiment, after determining the first power aggregation resource, the terminal may send the first information to the network device, so that the network device can determine the first power aggregation resource based on the first information and aggregate the power of the signal sent by the network device to the terminal onto the first power aggregation resource, so that the terminal can receive the signal on the first power aggregation resource, improving the data transmission rate of the terminal. It can be understood that the first power aggregation resource is the frequency-domain resource on the CC of the terminal where the channel quality meets the channel quality threshold. Therefore, the method provided in this embodiment can improve the improvement effect of the data transmission rate of the target terminal.

[0178] In some implementation manners, the network device may define one or more power aggregation modes, each power aggregation mode indicating a power aggregation resource. The terminal may measure the channel quality of the received signal on each power aggregation resource and feedback to the network device the channel quality measurement result corresponding to each power aggregation resource and / or the index of the power aggregation mode determined by the terminal based on the channel quality measurement result; the network device may determine the first power aggregation resource based on the information fed back by the terminal. In the embodiments of this application, the channel quality measurement result may also be referred to as the channel measurement result.

[0179] Exemplarily, Figure 5 FIG. is a schematic illustration of a communication method provided for another embodiment of the present application. As Figure 5 shown, the method may include S501, S502, and S503.

[0180] S501, the network device sends second information to the terminal, and the second information is used to configure at least one power aggregation mode.

[0181] In this embodiment, the network device may determine whether to actively initiate / perform power aggregation based on the channel quality information sent by the terminal, so as to improve the data transmission rate of the terminal. For example, when the channel quality of the terminal does not meet the channel quality threshold, power aggregation is initiated; when the channel quality of the terminal meets the channel quality threshold, power aggregation is not initiated. As an example, the terminal may periodically send the channel quality information of the signal received on the CC of the terminal to the network device.

[0182] As an example, the network device may also determine whether to initiate power aggregation based on the rate parameter configured for the terminal and / or the priority of the terminal. Among them, the rate parameter can be understood as a parameter used to indicate rate transmission, for example, it can be a data rate. The higher the priority of the terminal, the higher the requirement for channel quality. For example, when the data rate of the terminal is less than the rate threshold, power aggregation is initiated; when the data rate of the terminal is greater than or equal to the rate threshold, power aggregation is not initiated. Another example is to set different data rate thresholds and / or channel quality thresholds for the terminal according to different priorities.

[0183] As an example, if the network device determines that power aggregation needs to be initiated, the network device may send second information to the terminal, and the second information is used to configure at least one power aggregation pattern. For example, the network device may configure at least one power aggregation pattern for the terminal based on the real-time resource idle situation on the CC of the terminal, and send it to the terminal through the second information. Correspondingly, the terminal may receive the second information and determine at least one power aggregation pattern configured by the network device based on the second information. It should be noted that the present application does not specifically limit the design method of the power aggregation pattern. For example, it can be designed according to the actual network design or according to actual requirements. In some embodiments, the network device may also configure at least one power aggregation pattern for the terminal based on the capabilities of the terminal.

[0184] It should be noted that at least one power aggregation mode corresponds to at least one power aggregation resource one by one, and each power aggregation mode can indicate the corresponding power aggregation resource. Each power aggregation mode indicating the corresponding power aggregation resource can be understood as each power aggregation mode indicating the position of the corresponding power aggregation resource in the CC of the terminal, or each power aggregation mode indicating which frequency domain resources of the CC of the terminal are the corresponding power aggregation resources, or each power aggregation mode indicating to which frequency domain resources in the CC of the terminal the power is aggregated. [[ID=②]]

[0185] As an example, the second information may include the index of each power aggregation mode in at least one power aggregation mode and / or the granularity of the resource unit of the power aggregation resource corresponding to each power aggregation mode.

[0186] Figure 6 This is a schematic illustration of the power aggregation mode provided by an embodiment of the present application. Figure 6 Four power aggregation modes are shown, such as power aggregation mode 1, power aggregation mode 2, power aggregation mode 3, and power aggregation mode 4. As Figure 6 shown, the frequency domain resources composed of black blocks and white blocks can be understood as the CC of the terminal, and the black blocks can be understood as the power aggregation resources indicated by each power aggregation mode. It can be seen that the power aggregation resources indicated by power aggregation mode 1 include all resource units on the first half bandwidth of the CC of the terminal; the power aggregation resources indicated by power aggregation mode 2 include all resource units on the second half bandwidth of the CC of the terminal; the power aggregation resources indicated by power aggregation mode 3 include the odd resource units on the entire bandwidth of the CC of the terminal; the power aggregation resources indicated by power aggregation mode 4 include the even resource units on the entire bandwidth of the CC of the terminal.

[0187] In some embodiments, the frequency domain resources composed of black blocks and white blocks may also be part of the frequency domain resources in the CC of the terminal. For example, each square (such as a black block or a white block) may be 1 resource unit in the CC of the terminal, so the frequency domain resources composed of black blocks and white blocks are 6 resource units in the CC of the terminal.

[0188] As an example, the resource unit may be an RB, RBG, RE, BWP, sub-band, or REG, which is not limited herein.

[0189] As an example, the granularity of the resource unit can be understood as the number of resource units included in the power aggregation resource indicated by the power aggregation mode. As Figure 6 shown, in the power aggregation resources indicated by power aggregation mode 1, the granularity of the resource unit is 3. In this example, one square (such as a black block or a white block) represents one resource unit.

[0190] As an example, the granularity of the resource unit can be understood asFigure 6 The number of resource units included in a square (such as a black square or a white square). For example, when a square contains 1 RBG, the granularity of the resource unit is 1 RBG.

[0191] In some embodiments, the granularity of the resource unit may also be referred to as the granularity of power aggregation.

[0192] In an implementable manner, when the adjacent channel leakage ratio (ACLR) requirement or the out-of-band leakage standard is met, over-transmission of signal power is allowed. Over-transmission can be simply referred to as over-issue. For example, when the power aggregation resources indicated by the power aggregation mode do not include the frequency domain resources at the edge positions of the operating frequency band of the network device, or when the frequency domain resources adjacent to the power aggregation resources indicated by the power aggregation mode still belong to the frequency domain resources of the network device, the network device is allowed to over-issue the signal power. Among them, the edge positions of the operating frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the operating frequency band of the network device. The starting frequency domain position can be understood as the frequency domain position with a first preset offset from the starting frequency point of the operating frequency band, and the ending frequency domain position can be understood as the frequency domain position with a second preset offset from the ending frequency point of the operating frequency band. The first preset offset and the second preset offset can be set according to actual needs or obtained through signaling, and the present application does not make specific limitations in this regard. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the operating frequency band of the network device. The over-issue of the signal power can be understood as the power of the signal sent by the network device to the terminal being greater than the rated power of the signal. In the embodiments of the present application, the rated power of the signal can also be referred to as the rated value of the signal power.

[0193] As an example, the second information may further include indication information of the maximum over-issue power. Among them, the maximum over-issue power can be the over-issue amount of the signal power, or the sum of the over-issue amount of the signal power and the rated power, which is not limited herein. The over-issue amount of the signal power can be understood as the value by which the actual power of the signal sent by the network device to the terminal exceeds the rated power. It should be noted that the setting rule of the over-issue amount of the signal power can be determined according to actual network design and requirements, and the present application does not make limitations in this regard.

[0194] As an example, a larger over-issue amount can be allocated to the CC closer to the center frequency of the communication bandwidth. The CC closer to the center frequency of the communication bandwidth can be understood as the CC with a closer distance between the center frequency and the center frequency of the communication bandwidth. Therefore, the over-issue amount of the signal power on the CC of the terminal is different depending on the position of the CC of the terminal in the communication bandwidth.

[0195] It should be noted that due to the different capabilities of terminals, the number of CCs that a terminal can use can be one or more, that is, the number of CCs of the terminal can be one or more. For example, it is set that Figure 6 the frequency-domain resources composed of black blocks and white blocks in Figure 6 are the CCs of the terminal. When the frequency-domain resources composed of every three squares represent one CC, it is considered that the number of CCs of the terminal is 2; when the frequency-domain resources composed of every two squares represent one CC, it is considered that the number of CCs of the terminal is 3. Therefore, the power aggregation resources indicated by each power aggregation mode may be located within a certain CC or may be located between multiple CCs. The power aggregation resources being located between multiple CCs can be understood as the power aggregation resources indicated by the power aggregation mode being distributed on multiple CCs.

[0196] As an example, the maximum over-transmission power can be the over-transmission amount of the signal power corresponding to each power aggregation mode, that is, the over-transmission amount of the signal power sent by the network device to the terminal on the power aggregation resources indicated by the power aggregation mode. Among them, when the number of CCs of the terminal is multiple and the power aggregation resources indicated by the power aggregation mode are located between multiple CCs, the same or different maximum over-transmission powers can be allocated to the power aggregation resources located on different CCs, which is not specifically limited here.

[0197] Figure 7 This is a schematic diagram showing the over-transmission amount of a power aggregation mode provided by an embodiment of the present application. Figure 7 The signal powers corresponding to three power aggregation modes are shown, such as the signal powers corresponding to power aggregation mode 1, power aggregation mode 2, and power aggregation mode 3. f0 is the center frequency of the communication bandwidth. Among them, the white blocks can be understood as the rated values of the signal powers corresponding to each power aggregation mode, and it can be seen that the rated values of the signal powers corresponding to each power aggregation mode are the same; the shaded blocks can be understood as the over-transmission amounts of the signal powers corresponding to each power aggregation mode. It should be noted that Figure 7 mode 1 in Figure 7 represents power aggregation mode 1, mode 2 represents power aggregation mode 2, and mode 3 represents power aggregation mode 3.

[0198] Such as Figure 7 shown, the frequency-domain position of the power aggregation resources indicated by power aggregation mode 2 is closer to f0, then the over-transmission amount of the signal power corresponding to power aggregation mode 2 can be greater than the over-transmission amounts of the signal powers corresponding to power aggregation mode 1 and power aggregation mode 3.

[0199] As an example, when the power aggregation resources indicated by the power aggregation mode are located among multiple CCs, the second information may further include indication information about the positions of the power aggregation resources indicated by each power aggregation mode in the CCs of the terminal. This information can be used to indicate the starting position of the power aggregation resources in the CCs of the terminal. The terminal can determine the starting position of the power aggregation resources in the CCs of the terminal based on the indication information about the positions of the power aggregation resources indicated by each power aggregation mode in the CCs of the terminal, and determine the number of resource units included in the power aggregation resources based on the granularity of the resource units of the power aggregation resources, so as to determine the position distribution of all the resource units included in the power aggregation resources in the CCs of the terminal.

[0200] In some implementation manners, at least one power aggregation mode can be predefined by the protocol. In this implementation manner, the second information may only include the indexes of at least one power aggregation mode. The terminal can determine at least one power aggregation mode based on the indexes of at least one power aggregation mode.

[0201] In some implementation manners, the second information is further used to configure the measurement manner and / or reporting manner of the channel measurement results. As an example, the second information may include measurement configuration information. For example, the second information includes measurement reporting configuration and / or measurement resource configuration.

[0202] In this implementation manner, the terminal can determine what resources to measure based on the measurement resource configuration, and determine how to perform measurement and reporting through the measurement reporting configuration.

[0203] As an example, the network device can send the second information to the terminal through radio resource control (RRC) signaling.

[0204] S502. The terminal determines first information, where the first information is used to determine first power aggregation resources. The first power aggregation resources are used to aggregate the power of the signals sent by the network device to the terminal, and the first power aggregation resources are partial frequency domain resources in the CCs of the terminal.

[0205] In this embodiment, after receiving the second information, the terminal can determine the channel quality corresponding to each power aggregation mode based on the second information. The method for the terminal to measure the channel quality in this application is not specifically limited. For example, the terminal can determine the resources to be measured based on the measurement resource configuration, and determine how to perform measurement through the measurement reporting configuration, so as to measure the channel quality of the signals received on the power aggregation resources indicated by each power aggregation mode, and further determine the channel measurement results corresponding to each power aggregation mode.

[0206] As an example, a network device may send a pilot signal (such as a channel state information-reference signal (CSI-RS)) on the power aggregation resource indicated by the power aggregation mode, so that a terminal can determine the channel measurement result corresponding to the power aggregation mode by measuring the channel quality of receiving the CSI-RS on the power aggregation resource.

[0207] As an example, a network device may send a pilot signal (such as CSI-RS) on the CC of a terminal, so that the terminal can determine the channel measurement result of receiving the CSI-RS on the CC of the terminal by measuring the channel quality of receiving the CSI-RS on the CC of the terminal; the terminal can determine the channel measurement result corresponding to the power aggregation mode based on the channel measurement result of receiving the CSI-RS on the CC of the terminal and the power aggregation resource indicated by the power aggregation mode. Among them, when the signal power can be over-transmitted, when the terminal determines the channel measurement result corresponding to the power aggregation mode based on the channel measurement result of receiving the CSI-RS on the CC of the terminal and the power aggregation resource indicated by the power aggregation mode, the over-transmission amount of the signal power can also be taken into account, so as to improve the measurement accuracy of the channel measurement result corresponding to the power aggregation mode.

[0208] As an example, the channel measurement result may include one or more of the following: rank indication (RI), precoding matrix indicator (PMI), CQI, SINR, RSRP, reference signal received quality (RSRQ).

[0209] As an example, after the terminal determines the channel measurement result corresponding to each power aggregation mode, it may determine a first power aggregation mode in at least one power aggregation mode based on the channel quality measurement result. Among them, the first power aggregation resource may be a partial frequency domain resource in the CC of the terminal, or the first power aggregation resource is one or more resource units in the CC of the terminal. The network device may aggregate the power of the signal sent by the network device to the terminal onto the first power aggregation resource. It should be understood that the first power aggregation mode is included in at least one power aggregation mode, and the first power aggregation mode indicates the first power aggregation resource. [[ID=X]] [[ID=Y]]

[0210] As an example, the channel measurement result of receiving the signal on the first power aggregation resource meets the channel quality threshold. For example, the CQI of receiving the signal on the first power aggregation resource is greater than the CQI threshold.

[0211] As an example, when at least one power aggregation mode is predefined by the protocol, the terminal can directly execute S502 and S503 without executing S501 to save signaling overhead. For example, the terminal can determine the channel quality corresponding to each power aggregation mode based on the default measurement configuration information of channel measurement for at least one predefined power aggregation mode. In some embodiments, the measurement configuration information of channel measurement can also be predefined by the protocol or preconfigured in the terminal in advance, which is not limited herein.

[0212] S503, the terminal sends the first information to the network device.

[0213] In this embodiment, after determining the first power aggregation mode, the terminal can send the first information to the network device. For example, the terminal can determine the reporting method based on the measurement reporting configuration and thus report the first information to the network device.

[0214] As an example, the first information may include the index of the first power aggregation mode and / or the channel measurement result of the received signal on the first power aggregation resource. Correspondingly, the network device can receive the first information and determine the first power aggregation mode based on the first information, thereby determining the first power aggregation resource.

[0215] As an example, the first information may include the channel measurement result corresponding to each power aggregation mode in at least one power aggregation mode. After receiving the first information, the network device can determine the power aggregation mode corresponding to the channel measurement result that meets the channel quality threshold as the first power aggregation mode based on the channel measurement result corresponding to each power aggregation mode, thereby determining the first power aggregation resource.

[0216] As an example, the first information may include the indication information on whether signal power overshooting can be performed for each power aggregation mode in at least one power aggregation mode and / or the overshoot amount when signal power overshooting is performed for each power aggregation mode.

[0217] As an example, after receiving the first information, the network device can also determine the first power aggregation mode based on information such as the capabilities of the terminal, which is not specifically limited herein.

[0218] As an example, the terminal can report through the physical uplink control channel (PUCCH), or can report through the uplink control information (UCI), or the media access control - control element (MAC - CE), or the RRC signaling.

[0219] In this embodiment, the network device may pre-define at least one power aggregation mode. The terminal may measure the channel quality corresponding to each power aggregation mode and send first information to the network device. The first information may include the index of the first power aggregation mode and / or the channel measurement result corresponding to the first power aggregation mode, so that the network device may configure a corresponding power aggregation scheme based on the first power aggregation mode or configure downlink transmission information for the terminal. In the method provided in this embodiment, the network device may determine the first power aggregation mode from at least one power aggregation mode according to the feedback of the channel measurement result of the terminal, and concentrate the radio frequency power on the first power aggregation resource indicated by the first power aggregation mode, and the first power aggregation resource is a frequency domain resource whose channel quality meets the channel quality threshold, thereby significantly improving the user's network experience and increasing the data rate of the terminal. In addition, in the embodiment of the present application, the signal power may also be over-transmitted according to actual requirements to better increase the data rate of the terminal. The radio frequency power may be understood as the power of the signal sent by the network device to the terminal.

[0220] In some application scenarios, the network device may initiate power aggregation after receiving the request information sent by the terminal. For example, when the user uses the terminal to try to watch video content, but the current download rate of the terminal is not sufficient to support the smooth playback of the video content, the terminal may send request information to the network device to request to trigger power aggregation, so that the terminal can obtain higher transmission power or better signal quality to meet its quality of service requirements. Therefore, Figure 5 the method in may further include S510. For example, before executing S501, that is, before the network device sends the second information to the terminal, S510 is executed.

[0221] S510, the terminal sends third information to the network device, and the third information is used to request power aggregation.

[0222] In this embodiment, when the downlink transmission rate of the terminal or the channel quality cannot meet the quality of service requirements, the terminal may send third information to the network device to request the network device to initiate power aggregation, so as to improve the downlink transmission rate or channel quality of the terminal. Correspondingly, the network device may receive the third information.

[0223] As an example, the terminal may send the third information through UCI, MAC-CE or RRC signaling.

[0224] In some implementation manners, the terminal may also send fourth information to the network device, and the fourth information indicates the power aggregation modes supported by the terminal. Correspondingly, the network device may receive the fourth information.

[0225] As an example, the fourth information may include an index of the power aggregation mode supported by the terminal. The power aggregation mode supported by the terminal may be a power aggregation mode determined by the terminal itself. For example, the terminal may determine the power aggregation mode it wants to measure from at least one power aggregation mode and send it to the network device through the fourth information.

[0226] In some embodiments, the fourth information may further include the cell for which measurement is requested and / or the beam for which measurement is requested, so that the network device can configure the measurement method and / or reporting method of the channel measurement result for the terminal based on the fourth information.

[0227] As an example, the third information and the fourth information may be carried and sent in the same message, or may be carried and sent in different messages, which is not limited herein.

[0228] It should be understood that the network device may execute S501 after receiving the third information or the fourth information, so as to configure at least one power aggregation mode for the terminal.

[0229] In this embodiment, the network device may initiate power aggregation after receiving the request sent by the terminal, thereby effectively improving the data transmission rate of the terminal and meeting the service quality requirements of the terminal.

[0230] This application provides a more advanced and flexible power aggregation method / mechanism. In the technical solution provided by this application, at least one power aggregation mode can be predefined, or the network device can configure at least one power aggregation mode for the terminal, so that the terminal can determine the channel measurement results corresponding to each power aggregation mode in at least one power aggregation mode, and determine the first power aggregation mode from at least one power aggregation mode based on the channel measurement results corresponding to each power aggregation mode. In addition, the terminal can evaluate the potential impact of different power aggregation modes on the data rate of the terminal, for example, evaluate whether each power aggregation mode can perform overtransmission of signal power. The terminal can report the determined first power aggregation mode to the network device, so that the network device can more accurately adjust the power allocation strategy according to the information reported by the terminal, and can also achieve a certain degree of overtransmission of signal power, thereby more effectively improving the data rate of the terminal and improving the user experience. In the technical solution provided by this application, the terminal can determine the first power aggregation mode according to its own channel conditions and report it to the network device, so that the power allocation strategy configured by the network device for the terminal is more in line with the needs of the terminal, realizing the personalized optimization of the terminal; the network device can more effectively allocate radio frequency resources based on the reported information of the terminal, improving the spectrum utilization rate; the optimized power allocation strategy can provide users with more stable and high-quality communication services. The technical solution provided by this application enhances the adaptability and efficiency of the network, provides personalized quality of service optimization, and ultimately promotes the improvement of the performance of the entire wireless communication network.
