Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 30, 2024, with application number 202410137461.7 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a communication method and a communication device. Background Art

[0003] Wireless signals experience propagation loss during transmission, which affects signal transmission performance. For example, high-frequency signals experience significant transmission loss. Another example is significant transmission loss when wireless signals are transmitted to terminals at the edge of network coverage. Another example is significant transmission loss when wireless signals are transmitted from outdoor environments to terminals in indoor (O2I) scenarios.

[0004] A power aggregation solution to the above problem is as follows: by adjusting the resource allocation of wireless signals, the power on the component carriers (CCs) of other terminals is temporarily aggregated to the CC of the target terminal, thereby reducing the impact of wireless signal propagation loss and thereby increasing the data transmission rate of the target terminal.

[0005] However, the data transmission rate improvement effect of this power aggregation solution is not good. Summary of the Invention

[0006] The present application provides a communication method and a communication device, which can improve the data transmission rate of a terminal in a power aggregation solution.

[0007] In a first aspect, the present 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 a first power aggregation resource, where the first power aggregation resource is used to aggregate the power of a signal sent by a network device to the terminal, and the first power aggregation resource is part of the frequency domain resources in the component carrier of the terminal; and sending the first information to the network device.

[0008] As an example, the method may be executed by a terminal, or may be executed by a chip system, a hardware circuit and / or a software module applied in the terminal.

[0009] As an example, the terminal may be a terminal whose network performance is not satisfactory to a preset threshold. The network device may perform power aggregation on the terminal to improve the network performance of the terminal.

[0010] As an example, network performance can be determined by the following performance indicators: downlink rate, reference signal receiving power (RSRP), and channel quality indicator (CQI). Among them, the network performance does not meet the preset threshold and 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 CQI value is less than the channel quality threshold. Among them, the rate threshold, power threshold, and channel quality threshold can be set according to actual needs and are not limited here.

[0011] As an example, the first power aggregation resource may be a frequency domain resource in a component carrier (CC) of the terminal that is idle and whose channel quality satisfies a channel quality threshold. For example, the terminal may determine the first power aggregation resource based on channel quality information of a signal received on the terminal's CC. The terminal may periodically or aperiodically report the channel quality information of the signal received on the terminal's CC to the network device.

[0012] In this technical solution, after determining the first power aggregation resource, the terminal can send 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 an idle frequency domain resource 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.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the first power aggregation resource is part of the frequency domain resources 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.

[0014] As an example, the first power aggregation resource may be 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 part of the bandwidth (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 other, and no specific limitation is given here.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the first information includes an index of a first power aggregation mode and / or a channel measurement result of a signal received on the first power aggregation resource, and the first power aggregation mode indicates the first power aggregation resource.

[0016] As an example, the first power aggregation resource may be indicated by a first power aggregation mode. For example, the first power aggregation mode may indicate the first power aggregation resource by indicating a position of the first power aggregation resource in a CC of the terminal, thereby indicating how to allocate power of a signal sent by the network device to the terminal on the CC of the terminal.

[0017] As an example, the first power aggregation mode may be predefined by a protocol.

[0018] 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.

[0019] As an example, after determining the first power aggregation resource, the terminal may send a channel measurement result of a signal received on the first power aggregation resource to the network device, so that the network device may determine the first power aggregation resource based on the received channel measurement result.

[0020] In combination with the first aspect, in certain implementations of the first aspect, a channel measurement result of a signal received on the first power aggregation resource meets a channel quality threshold.

[0021] As an example, the number of the first power aggregation resources may be one or more.

[0022] As an example, the terminal may send a first power aggregation resource indicating that a channel measurement result satisfies a channel quality threshold to the network device.

[0023] In some embodiments, the terminal may send the first power aggregation resource with the best channel measurement result to the network device.

[0024] 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).

[0025] As an example, the optimal channel measurement result may be the highest CQI, or the higher SINR, or the best RSRQ.

[0026] 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.

[0027] As an example, the first power aggregation mode may be configured by a network device. For example, the network device may configure the first power aggregation mode by sending second information to the terminal, where the second information may indicate parameters of the first power aggregation mode. Accordingly, the terminal may receive the second information.

[0028] In combination with the first aspect, in certain implementations of the first aspect, the second information includes an index of the first power aggregation mode and / or a granularity of a resource unit of the first power aggregation resource.

[0029] As an example, the index of the first power aggregation mode is 1, 2, ..., K, where K is a positive integer.

[0030] 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.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the first power aggregation resources include: 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.

[0032] As an example, the first power aggregation resource may include all resource units on the first half of the bandwidth in the CC of the terminal, or may include all resource units on the first half of the 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.

[0033] With reference to the first aspect, in certain implementations of the first aspect, the second information includes indication information of a maximum over-transmission power and / or indication information of a position of the first power aggregation resource in the component carrier.

[0034] As an example, when the adjacent channel leakage ratio (ACLR) requirement or the out-of-band leakage standard is met, excess transmission (over-transmission) of signal power is allowed. For example, when the first power aggregation resource does not include frequency domain resources located at the edge of the working 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. The edge position of the working frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the working 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 working 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 working frequency band. The first preset offset and the second preset offset can be set according to actual needs, or obtained through signaling, and this application does not make specific restrictions on this. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the working frequency band of the network device. Over-transmission of 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, depending on the capabilities of the terminal, the number of CCs that the terminal can use may be one or more, that is, the number of CCs of the terminal may be one or more.

[0035] As an example, the second information may also include indication information of the position of the first power aggregation resource in the CC of the terminal. For example, the indication information of 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 unit in the CC of the terminal the starting position of the first power aggregation resource is, or which resource unit in the CC of the terminal the starting resource unit contained in the first power aggregation resource is. 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 of the position of the first power aggregation resource in the CC of the terminal, and determine the number of resource units contained in the first power aggregation resource based on the granularity of the resource units of the first power aggregation resource, thereby determining the position distribution of all resource units contained in the first power aggregation resource in the CC of the terminal. For another example, the indication information of the position of the first power aggregation resource in the CC of the terminal may indicate the positions of all resource units contained in the first power aggregation resource in the CC of the terminal.

[0036] In this implementation, over-transmission of signal power is allowed, which can further improve the data transmission rate of the terminal.

[0037] In combination with the first aspect, in some implementations of the first aspect, the second information is further used to configure a measurement method and / or a reporting method of the channel measurement result.

[0038] As an example, the second information may include measurement configuration information. For example, the second information may include measurement report configuration and / or measurement resource configuration.

[0039] In this implementation, 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 that the channel quality of the received signal on the first power aggregation resource can be measured and reported to the network device.

[0040] In combination with the first aspect, in some implementations 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.

[0041] As an example, when the downlink transmission rate or channel quality of the terminal cannot meet the service quality requirements, third information can be sent to the network device to request the network device to initiate power aggregation, thereby improving the downlink transmission rate or channel quality of the terminal.

[0042] In combination with the first aspect, in some implementations of the first aspect, the method further includes: sending fourth information to the network device, where the fourth information indicates a power aggregation mode supported by the terminal.

[0043] As an example, the power aggregation mode supported by the terminal may be a power aggregation mode autonomously determined by the terminal.

[0044] As an example, the fourth information may also include the cell requested for measurement and / or the beam requested for measurement, so that the network device can configure the measurement method and / or reporting method of the channel measurement results for the terminal based on the fourth information.

[0045] As an example, the third information and the fourth information may be carried in the same message and sent, or may be carried in different messages and sent, which is not limited here.

[0046] In a second aspect, the present application provides a communication method, which is applied to a network device, and the method includes: receiving first information from a terminal, the first information being used to determine a first power aggregation resource, the first power aggregation resource being used to aggregate the power of a signal sent by the network device to the terminal, the first power aggregation resource being part of a frequency domain resource in a component carrier of the terminal; and sending a signal to the terminal based on the first information.

[0047] As an example, the method may be executed by a network device, or may be executed by a chip system, a hardware circuit and / or a software module applied to the network device.

[0048] As an example, the terminal may be a terminal whose network performance is not satisfactory to a preset threshold. The network device may perform power aggregation on the terminal to improve the network performance of the terminal.

[0049] As an example, network performance can be determined using the following performance indicators: downlink rate, RSRP, and CQI. Network performance failing to meet a preset threshold may include at least one of the following: a downlink rate less than a rate threshold, RSRP less than a power threshold, or a CQI value less than a channel quality threshold. The rate threshold, power threshold, and channel quality threshold can be set based on actual needs and are not limited here.

[0050] As an example, the first power aggregation resource may be a frequency domain resource in a CC of the terminal that is idle and whose channel quality satisfies a channel quality threshold. For example, the terminal may determine the first power aggregation resource based on channel quality information of signals received on the CC of the terminal. The terminal may periodically or aperiodically report the channel quality information of signals received on the CC of the terminal to the network device.

[0051] In this technical solution, the network device can receive first information sent by the terminal, and after determining a first power aggregation resource based on the first information, 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 an idle frequency domain resource 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.

[0052] In combination with the second aspect, in certain implementations of the second aspect, the first power aggregation resource is part of the frequency domain resources 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.

[0053] As an example, the first power aggregation resource may be part of the frequency domain resources in the CC of the terminal. For example, the first power aggregation resource may be one or more RBs in the CC of the terminal, or one or more RBGs in the CC of the terminal, or one or more REs in the CC of the terminal, or one or more REGs in the CC of the terminal, or a BWP in the CC of the terminal, or 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 other terms, which are not specifically limited herein.

[0054] In combination with the second aspect, in certain implementations of the second aspect, the first information includes an index of a first power aggregation mode and / or a channel measurement result of a signal received on the first power aggregation resource, and the first power aggregation mode indicates the first power aggregation resource.

[0055] As an example, the first power aggregation resource may be indicated by a first power aggregation mode. For example, the first power aggregation mode may indicate the first power aggregation resource by indicating a position of the first power aggregation resource in a CC of the terminal, thereby indicating how to allocate power of a signal sent by the network device to the terminal on the CC of the terminal.

[0056] As an example, the first power aggregation mode may be predefined by a protocol.

[0057] 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.

[0058] As an example, after determining the first power aggregation resource, the terminal can send the channel measurement result of the signal received on the first power aggregation resource to the network device; accordingly, the network device can receive the channel measurement result sent by the terminal and determine the first power aggregation resource based on the received channel measurement result.

[0059] In combination with the second aspect, in certain implementations of the second aspect, a channel measurement result of a signal received on the first power aggregation resource meets a channel quality threshold.

[0060] As an example, the number of the first power aggregation resources may be one or more.

[0061] As an example, the terminal may send a first power aggregation resource indicating that a channel measurement result satisfies a channel quality threshold to the network device.

[0062] In some embodiments, the terminal may send the first power aggregation resource with the best channel measurement result to the network device.

[0063] As an example, the channel measurement result may include one or more of the following: RI, PMI, CQI, SINR, RSRP, and RSRQ.

[0064] As an example, the optimal channel measurement result may be the highest CQI, or the higher SINR, or the best RSRQ.

[0065] In combination with the second aspect, in some implementations 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.

[0066] 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, where the second information may indicate parameters of the first power aggregation mode.

[0067] As an example, the network device may configure the first power aggregation mode for the terminal according to a real-time resource idleness condition in the CC of the terminal.

[0068] In combination with the second aspect, in certain implementations of the second aspect, the second information includes an index of the first power aggregation mode and / or a granularity of a resource unit of the first power aggregation resource.

[0069] As an example, the index of the first power aggregation mode is 1, 2, ..., K, where K is a positive integer.

[0070] 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.

[0071] In combination with the second aspect, in certain implementations of the second aspect, the first power aggregation resources include: 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.

[0072] As an example, the first power aggregation resource may include all resource units on the first half of the bandwidth in the CC of the terminal, or may include all resource units on the first half of the 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.

[0073] With reference to the second aspect, in certain 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.

[0074] As an example, when the ACLR requirements or out-of-band leakage standards are met, excess transmission (over-transmission) of signal power is allowed. For example, when the first power aggregation resource does not include frequency domain resources located at the edge of the working 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. The edge position of the working frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the working 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 working 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 working frequency band. The first preset offset and the second preset offset can be set according to actual needs, or obtained through signaling, and this application does not make specific restrictions on this. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the working frequency band of the network device. Over-transmission of 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 can also include the maximum over-transmission power. It should be noted that, due to different capabilities of terminals, the number of CCs that can be used by the terminal may be one or more, that is, the number of CCs of the terminal may be one or more.

[0075] As an example, the second information may also include indication information of the position of the first power aggregation resource in the CC of the terminal. For example, the indication information of 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 unit in the CC of the terminal the starting position of the first power aggregation resource is, or which resource unit in the CC of the terminal the starting resource unit contained in the first power aggregation resource is. 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 of the position of the first power aggregation resource in the CC of the terminal, and determine the number of resource units contained in the first power aggregation resource based on the granularity of the resource units of the first power aggregation resource, thereby determining the position distribution of all resource units contained in the first power aggregation resource in the CC of the terminal. For another example, the indication information of the position of the first power aggregation resource in the CC of the terminal may indicate the positions of all resource units contained in the first power aggregation resource in the CC of the terminal.

[0076] In this implementation, over-transmission of signal power is allowed, which can further improve the data transmission rate of the terminal.

[0077] In combination with the second aspect, in some implementations of the second aspect, the second information is further used to configure a measurement method and / or a reporting method of the channel measurement result.

[0078] As an example, the second information may include measurement configuration information. For example, the second information includes measurement report configuration and / or measurement resource configuration.

[0079] In this implementation, the network device can configure measurement configuration information to the terminal through the second information, so that 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 that the channel quality of the received signal on the first power aggregation resource can be measured and reported to the network device.

[0080] In combination with the second aspect, in some implementations of the second aspect, the method further includes: receiving third information from the terminal, where the third information is used to request power aggregation.

[0081] For example, when the terminal's downlink transmission rate or channel quality fails to meet quality of service requirements, a third message may be sent to the network device to request the network device to initiate power aggregation, thereby improving the terminal's downlink transmission rate or channel quality. Accordingly, the network device may receive the third message and send a power aggregation request.

[0082] 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 a power aggregation mode supported by the terminal.

[0083] As an example, the power aggregation mode supported by the terminal may be a power aggregation mode determined autonomously by the terminal. After receiving the fourth information, the network device may determine the second information based on the fourth information.

[0084] As an example, the fourth information may also include the cell requested for measurement and / or the beam requested for measurement, so that the network device can configure the measurement method and / or reporting method of the channel measurement results for the terminal based on the fourth information.

[0132] In an embodiment of the present application, a network device is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The network device may include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. In systems using different wireless access technologies, the names of network devices may be different, such as base transceiver stations (BTS) in GSM or CDMA networks, node B (NB) in WCDMA, and evolutionary node B (eNB or eNodeB) in LTE. The network device can also be a wireless controller in a cloud radio access network (CRAN) scenario.

[0133] In the embodiments of the present application, a 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 with wireless communication functions.

[0134] The network equipment can provide services for the terminals within the cell. The terminals communicate with the network equipment or other devices corresponding to the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network equipment. The network equipment can be a macro base station (for example, macro eNB or macro gNB, etc.), or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0135] For example, Figure 1 is a schematic diagram of a communication system applicable to an embodiment of the present application. As shown in Figure 1, the communication system may include multiple network devices (such as base station 110, base station 120, and base station 130 in Figure 1) and terminal 140. The number of network devices and terminals is only an example and is not limited in this application. It should be understood that Figure 1 is only a schematic diagram, and the communication system may also include other network devices, such as core network devices, which are not shown in Figure 1.

[0136] Taking base station 110 among multiple network devices as an example, base station 110 can provide communication services to terminal 140 within a cell. Base station 110 can send downlink information to terminal 140. This downlink information can be control information or data information, which is not limited in this application. Terminal 140 can also send uplink information to base station 110. In some embodiments, multiple network devices can simultaneously transmit data or control signaling to terminal 140.

[0137] For example, FIG2 is a schematic diagram illustrating another communication system applicable to an embodiment of the present application. As shown in FIG2 , the communication system may include a terminal 210 and a network device 220. The terminal 210 includes a processor 211, a memory 212, and a transceiver 213. The transceiver 213 includes a transmitter 2131, a receiver 2132, and an antenna 2133. The memory 212 is used to store computer program code. The processor 211 can call the computer program code to enable the terminal 210 to implement relevant functions. 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. The processor 221 can call the computer program code to enable the network device 220 to implement relevant functions. Receiver 2132 may be configured to receive transmission control information sent by network device 220 via antenna 2133, and transmitter 2131 may be configured to send transmission feedback information to network device 220 via antenna 2133. Transmitter 2231 may be configured to send transmission control information to terminal 210 via antenna 2233, and receiver 2232 may be configured to receive transmission feedback information sent by terminal 210 via antenna 2233.

[0138] The technical problem solved by this application is described below with reference to FIG3 .

[0139] Wireless signals experience propagation loss during transmission, which affects signal transmission performance. For example, high-frequency signals experience significant transmission loss due to factors such as free-space loss and atmospheric absorption. Free-space loss can be understood as the basic loss of high-frequency signals propagating in free space, which is proportional to the square of the frequency. Atmospheric absorption refers to the absorption of high-frequency signals by atmospheric molecules (such as water vapor) during propagation, which increases with increasing frequency. For another example, terminals at the edge of network coverage are far away from network equipment, resulting in significant transmission loss when wireless signals are transmitted to terminals at the edge of network coverage. Another example is significant transmission loss when wireless signals are transmitted from outdoor environments to terminals in outdoor-to-indoor (O2I) scenarios. It should be noted that O2I describes the process of signal transmission from outdoor environments to indoor environments. In O2I scenarios, signals must pass through building walls, windows, and other possible obstacles to reach indoor receivers (such as terminals).

[0140] A power aggregation solution to the above problem is as follows: by adjusting the resource allocation of wireless signals, the power on the component carriers (CCs) of other terminals is temporarily aggregated 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 loss and further improving the data transmission rate of the target terminal. The target terminal may include a terminal at the edge of network coverage, an indoor and outdoor (O2I) terminal, and a terminal with a download rate less than or equal to a download threshold (such as 100 million bits per second (Mbps)). In the embodiment 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 refocusing, or power boosting, which is not specifically limited in this application. Through power aggregation, the data transmission rate and service experience of the target terminal can be improved without significantly increasing the total power consumption of the network. The component carrier can also be referred to as a carrier component. The data transmission rate can also be referred to as 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 a terminal can be understood as the frequency domain resources allocated to the terminal by the network device when providing network services to the terminal.

[0141] For example, Figure 3 is a schematic flow chart of a power aggregation method. As shown in Figure 3 , the method may include S301 to S305.

[0142] S301: Determine the target terminal.

[0143] As an example, the target terminal may be understood as a terminal whose network performance does not meet a preset threshold.

[0144] As an example, the network performance may be determined by the following performance indicators: downlink rate, reference signal receiving power (RSRP) and channel quality indicator (CQI).

[0145] As an example, network performance failing to meet a preset threshold may include at least one of the following: a downlink rate less than a rate threshold, an RSRP less than a power threshold, or a CQI value less than a channel quality threshold. The rate threshold, power threshold, and channel quality threshold can be set based on actual needs and are not limited here.

[0146] As an example, the terminal may 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.

[0147] S302: Determine a first CC.

[0148] As an example, the network device may configure a CC for each terminal in a cell, so that the terminal can receive signals on the CC.

[0149] As an example, the first CC may be understood as a CC whose power usage is less than a usage threshold. It should be noted that the power of a CC may be understood as the power allocated by the network device to the CC, or the power of a signal sent by the network device to the terminal on the CC.

[0150] As an example, the network device may determine or evaluate the power usage of CCs of all terminals in the cell and determine a CC with a power usage rate less than a usage rate threshold as the first CC. It should be understood that there may be one or more first CCs.

[0151] S303: Perform power aggregation.

[0152] As an example, after determining the first CC, the network device may temporarily aggregate or allocate the power on the first CC to the CC of the target terminal. For example, the network device may temporarily stop allocating power to the first CC and aggregate the power not allocated to the first CC to the CC of the target terminal, thereby increasing the power of the signal sent by the network device to the target terminal, thereby improving the data transmission rate of the target terminal.

[0153] In addition, after implementing power aggregation, the network equipment can monitor the RSRP and signal-to-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 has not changed, 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.

[0154] When the signal quality of the target terminal is not improved, S302 to S303 may be repeatedly performed until the signal quality of the target terminal is improved.

[0155] S304: Improve the modulation and coding scheme level of the target terminal.

[0156] For example, after the signal quality of the target terminal improves, the network device needs to correspondingly increase the modulation and coding scheme (MCS) level of the target terminal so that the MCS level can adapt to the change in signal quality, increasing the data rate of the target terminal and network throughput, and ensuring the reliability of data transmission. It should be noted that the higher the terminal's SINR, the better the signal quality, and the higher the terminal's CQI, the higher the terminal's MCS level should be.

[0157] S305: Monitor and optimize the power convergence solution.

[0158] As an example, the network device may 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 signal quality, service quality, or network performance improvement effect of the target terminal does not reach a preset threshold, S302 to S304 may be repeated to re-evaluate the first CC, adjust the power aggregation strategy, and select and configure the MCS.

[0159] In some embodiments, the terminals within 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 from the terminals within the cell, so as to facilitate the network device to adjust the power aggregation strategy and optimize the MCS configuration.

[0160] The method in FIG3 enables network equipment (such as a base station) to reallocate power to the CC of a target terminal without increasing the total radio frequency power, thereby increasing the power on the CC of the target terminal and improving the communication quality and data rate of the target terminal.

[0161] However, the power aggregation method in FIG3 has certain limitations in terms of power allocation and frequency domain resource utilization, resulting in a poor effect on improving the data transmission rate of the target terminal. For example, the power aggregation method in FIG3 assumes that the target terminal can use all available frequency domain resources in the target CC, so the network device aggregates power on all available frequency domain resources in the target CC, or in other words, the network device aggregates / allocates 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, so the target terminal may not be able to use all available frequency domain resources in the target CC, resulting in the power aggregated in the target CC not being fully utilized, thereby failing to fully improve the data rate of the target terminal. In addition, the power aggregation method in FIG3 does not take into account that different frequency domain resources may have different channel qualities, and ignores the importance of channel quality in improving the data rate of the target terminal, thereby failing to fully improve the data rate of the target terminal. The target CC can be understood as the CC of the target terminal.

[0162] Based on this, the applicant proposes that the first power can be aggregated to the frequency domain resources in the first frequency domain resources that are idle and whose channel quality meets the channel quality threshold, thereby optimizing the existing power aggregation method or power aggregation strategy, thereby effectively enhancing the signal quality of the target terminal and thus improving the service experience of the target terminal. The first frequency domain resources can be understood as the frequency domain resources that can be used by the target terminal in the target CC.

[0163] In view of this, the present application provides a communication method and communication device. In the technical solution provided in this application, the network device can determine the frequency domain resources for power aggregation in the target CC based on the measurement feedback of the terminal, or determine which frequency domain resources in the target CC to aggregate power to, thereby effectively improving the signal quality of the target terminal and thus improving the service experience of the target terminal.

[0164] The technical solution provided by this application is described in detail below with reference to Figures 4 to 7.

[0165] Figure 4 is a schematic diagram illustrating a communication method provided by an embodiment of the present application. As shown in Figure 4, the method may include S401 and S402.

[0166] As an example, this method can be executed by a terminal, or by a chip system, hardware circuit, and / or software module implemented in the terminal. It should be understood that the terminal in this embodiment can be understood as a terminal whose network performance is not satisfactory to a preset threshold. The network device can perform power aggregation on the terminal to improve the terminal's network performance.

[0167] S401, determine first information, where the first information is used to determine a first power aggregation resource, where the first power aggregation resource is used to aggregate power of a signal sent by a network device to a terminal, and the first power aggregation resource is part of frequency domain resources in a CC of the terminal.

[0168] As an example, the first power aggregation resource may be 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 units in the CC of the terminal, and the resource unit may be a resource block (RB), a resource block group (RBG), a resource element (RE), a bandwidth part (BWP), a subband, or a resource element group (REG). In some embodiments, the resource unit may also be referred to as a frequency domain resource or a frequency domain resource unit, which is not limited here.

[0169] As an example, the first power aggregation resource may be a frequency domain resource in a CC of the terminal that is idle and whose channel quality satisfies a channel quality threshold. The channel quality threshold may be set according to actual needs and is not limited in this application.

[0170] As an example, the terminal may determine the first power aggregation resource based on the channel quality information of the signal received on the CC of the terminal. It should be noted that the terminal may periodically or non-periodically report the channel quality information of the signal received on the CC of the terminal to the network device. For example, the terminal may determine the frequency domain resources on the CC of the terminal that are idle and whose channel quality meets the channel quality threshold based on the most recently reported channel quality information, and determine the frequency domain resources on the CC of the terminal that are idle and whose channel quality meets the channel quality threshold as the first power aggregation resource. Among them, the most recent report can be understood as the report that is closest to the current time. For another example, the terminal may determine the frequency domain resources on the CC of the terminal that are idle and whose channel quality meets the channel quality threshold based on the channel quality information reported multiple times recently, thereby determining the first power aggregation resource. The channel quality information may include CQI.

[0171] As an example, the network device may aggregate the power of the signal sent by the network device to the terminal onto the first power aggregation resource. The power of the signal sent by the network device to the terminal may be the power on the target CC after power aggregation is performed.

[0172] As an example, the first information may include indication information of the first power aggregation resource, so that the network device may determine the first power aggregation resource based on the first information.

[0173] S402: Send first information to the network device.

[0174] In this embodiment, after determining the first power aggregation resource, the terminal may send first information to the network device. Accordingly, the network device may receive the first information and determine the first power aggregation resource based on the first information and the capability of the terminal.

[0175] 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.

[0176] As an example, the network device may send configuration information to the terminal via 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.

[0177] 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 terminal's capabilities and the channel quality information reported by the terminal.

[0178] In this embodiment, after determining the first power aggregation resource, the terminal can send 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 to the first power aggregation resource, so that the terminal can receive the signal on the first power aggregation resource, thereby improving the data transmission rate of the terminal. It can be understood that the first power aggregation resource is a frequency domain resource whose channel quality on the CC of the terminal meets the channel quality threshold. Therefore, the method provided in this embodiment can improve the data transmission rate of the target terminal.

[0179] In some implementations, 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 signal received on each power aggregation resource and provide feedback to the network device on 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 embodiments of the present application, the channel quality measurement result may also be referred to as a channel measurement result.

[0180] For example, Figure 5 is a schematic diagram illustrating a communication method provided in another embodiment of the present application. As shown in Figure 5 , the method may include S501, S502, and S503.

[0181] S501: A network device sends second information to a terminal, where the second information is used to configure at least one power aggregation mode.

[0182] In this embodiment, the network device can determine whether to proactively initiate / perform power aggregation based on the channel quality information transmitted by the terminal, thereby improving the terminal's data transmission rate. For example, if the terminal's channel quality does not meet the channel quality threshold, power aggregation is initiated; if the terminal's channel quality meets the channel quality threshold, power aggregation is not initiated. As an example, the terminal can periodically transmit channel quality information of the signal received on its CC to the network device.

[0183] 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. The rate parameter may be understood as a parameter indicating the rate transmission, such as the 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. For another example, different data rate thresholds and / or channel quality thresholds may be set for terminals with different priorities.

[0184] As an example, if the network device determines that power convergence needs to be initiated, the network device may send a second information to the terminal, and the second information is used to configure at least one power convergence mode (pattern). For example, the network device may configure at least one power convergence mode for the terminal based on the real-time resource idleness on the CC of the terminal, and send it to the terminal through the second information. Accordingly, the terminal may receive the second information and determine at least one power convergence mode configured by the network device based on the second information. It should be noted that this application does not specifically limit the design method of the power convergence mode. For example, it can be designed according to the actual network design or according to actual needs. In some embodiments, the network device may also configure at least one power convergence mode for the terminal based on the capabilities of the terminal.

[0185] It should be noted that at least one power aggregation mode corresponds one-to-one to at least one power aggregation resource, and each power aggregation mode can indicate a corresponding power aggregation resource. Each power aggregation mode indicates a corresponding power aggregation resource, which can be understood as each power aggregation mode indicating the position of the corresponding power aggregation resource in the terminal's CC, or each power aggregation mode indicates which frequency domain resources in the terminal's CC the corresponding power aggregation resources are, or each power aggregation mode indicates which frequency domain resources in the terminal's CC are to be aggregated.

[0186] As an example, the second information may include an index of each power aggregation mode in at least one power aggregation mode and / or a granularity of a resource unit of a power aggregation resource corresponding to each power aggregation mode.

[0187] Figure 6 is a schematic diagram illustrating the power aggregation mode provided by an embodiment of the present application. Figure 6 shows four power aggregation modes, such as power aggregation mode 1, power aggregation mode 2, power aggregation mode 3 and power aggregation mode 4. As shown in Figure 6, 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 odd resource units on the entire bandwidth of the CC of the terminal; the power aggregation resources indicated by power aggregation mode 4 include even resource units on the entire bandwidth of the CC of the terminal.

[0188] In some embodiments, the frequency domain resources composed of the black blocks and the white blocks may also be part of the frequency domain resources in the CC of the terminal. For example, each block (such as a black block or a white block) may be one resource unit in the CC of the terminal. Therefore, the frequency domain resources composed of the black blocks and the white blocks are six resource units in the CC of the terminal.

[0189] As an example, the resource unit may be an RB, an RBG, an RE, a BWP, a subband, or a REG, which is not limited here.

[0190] As an example, the granularity of resource units can be understood as the number of resource units contained in the power aggregation resource indicated by the power aggregation mode. As shown in Figure 6, the granularity of resource units in the power aggregation resource indicated by power aggregation mode 1 is 3. In this example, a square (such as a black block or a white block) represents a resource unit.

[0191] As an example, the granularity of the resource unit can be understood as the number of resource units contained in a block (such as a black block or a white block) in Figure 6. For example, when a block contains one RBG, the granularity of the resource unit is one RBG.

[0192] In some embodiments, the granularity of resource units may also be referred to as the granularity of power aggregation.

[0193] In one achievable manner, when the adjacent channel leakage ratio (ACLR) requirement or the out-of-band leakage standard is met, excess emission of signal power is allowed. Excess emission can be referred to as over-emission. For example, when the power aggregation resources indicated by the power aggregation mode do not include frequency domain resources located at the edge of the working 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-emit signal power. The edge position of the working frequency band of the network device can be understood as the starting frequency domain position and the ending frequency domain position of the working 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 working 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 working frequency band. The first preset offset and the second preset offset can be set according to actual needs, or obtained through signaling, and this application does not make specific limitations on this. The frequency domain resources of the network device can be understood as the frequency domain resources corresponding to the working frequency band of the network device. Over-transmission of 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 embodiment of the present application, the rated power of the signal can also be referred to as the rated value of the signal power.

[0194] As an example, the second information may also include information indicating the maximum over-transmission power. The maximum over-transmission power may be the amount of over-transmission of signal power, or the sum of the over-transmission of signal power and the rated power, without limitation herein. The over-transmission of signal power may 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 rules for the over-transmission of signal power may be determined based on actual network design and requirements, and this application does not impose any limitations thereon.

[0195] For example, a CC closer to the center frequency of the communication bandwidth can be allocated a larger over-transmission amount. CCs closer to the center frequency of the communication bandwidth can be understood as CCs whose center frequencies are closer to the center frequency of the communication bandwidth. Therefore, depending on the location of a CC in the communication bandwidth, the over-transmission amount of signal power on that CC varies.

[0196] It should be noted that due to the different capabilities of the terminals, the number of CCs that the terminal can use may be one or more, that is, the number of CCs of the terminal may be one or more. For example, let the frequency domain resources composed of black blocks and white blocks in Figure 6 be the CCs of the terminal. If the frequency domain resources composed of every three blocks represent one CC, the number of CCs of the terminal is considered to be 2; if the frequency domain resources composed of every two blocks represent one CC, the number of CCs of the terminal is considered to be 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 over multiple CCs.

[0197] As an example, the maximum over-transmission power may be the over-transmission amount of signal power corresponding to each power aggregation mode, that is, the over-transmission amount of signal power sent by the network device to the terminal on the power aggregation resources indicated by the power aggregation mode. If the terminal has multiple CCs and the power aggregation resources indicated by the power aggregation mode are located across multiple CCs, the same or different maximum over-transmission powers may be allocated to the power aggregation resources located on different CCs, without specific limitation herein.

[0198] Figure 7 is a schematic diagram illustrating the over-transmission of a power convergence mode provided by an embodiment of the present application. Figure 7 shows the signal powers corresponding to three power convergence modes, such as the signal powers corresponding to power convergence mode 1, power convergence mode 2, and power convergence mode 3, and 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 convergence mode, and it can be seen that the rated values ​​of the signal powers corresponding to each power convergence mode are the same; the shaded blocks can be understood as the over-transmission of the signal powers corresponding to each power convergence mode. It should be noted that mode 1 in Figure 7 represents power convergence mode 1, mode 2 represents power convergence mode 2, and mode 3 represents power convergence mode 3.

[0199] As shown in Figure 7, the frequency domain position of the power aggregation resource indicated by power aggregation mode 2 is closer to f0, so the over-transmission of signal power corresponding to power aggregation mode 2 can be greater than the over-transmission of signal power corresponding to power aggregation mode 1 and power aggregation mode 3.

[0200] As an example, when the power aggregation resource indicated by the power aggregation mode is located between multiple CCs, the second information may also include indication information of the position of the power aggregation resource indicated by each power aggregation mode in the CC of the terminal. This information can be used to indicate the starting position of the power aggregation resource in the CC of the terminal. The terminal can determine the starting position of the power aggregation resource in the CC of the terminal based on the indication information of the position of the power aggregation resource indicated by each power aggregation mode in the CC of the terminal, and determine the number of resource units included in the power aggregation resource based on the granularity of the resource unit of the power aggregation resource, thereby determining the position distribution of all resource units included in the power aggregation resource in the CC of the terminal.

[0201] In some implementations, at least one power aggregation mode may be predefined by a protocol. In this implementation, the second information may only include an index of the at least one power aggregation mode. The terminal may determine the at least one power aggregation mode based on the index of the at least one power aggregation mode.

[0202] In some implementations, the second information is further used to configure a measurement method and / or a reporting method for the channel measurement results. As an example, the second information may include measurement configuration information. For example, the second information includes a measurement report configuration and / or a measurement resource configuration.

[0203] In this implementation, the terminal may determine what resources to measure based on the measurement resource configuration, and determine how to perform measurement and reporting through the measurement reporting configuration.

[0204] As an example, the network device may send the second information to the terminal through radio resource control (RRC) protocol signaling.

[0205] S502, the terminal determines first information, where the first information is used to determine a first power aggregation resource, where the first power aggregation resource is used to aggregate power of a signal sent by a network device to the terminal, and the first power aggregation resource is part of the frequency domain resources in the CC of the terminal.

[0206] In this embodiment, after receiving the second information, the terminal may determine the channel quality corresponding to each power aggregation mode based on the second information. This application does not specifically limit the method by which the terminal measures channel quality. For example, the terminal may determine the resources to be measured based on the measurement resource configuration, determine how to perform the measurement through the measurement reporting configuration, and thereby measure the channel quality of the received signal on the power aggregation resources indicated by each power aggregation mode, thereby determining the channel measurement result corresponding to each power aggregation mode.

[0207] As an example, the network device can 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 the terminal can determine the channel measurement result corresponding to the power aggregation mode by measuring the channel quality of the CSI-RS received on the power aggregation resource.

[0208] As an example, the network device may send a pilot signal (such as CSI-RS) on the CC of the terminal, so that the terminal can determine the channel measurement result of the CSI-RS received on the CC of the terminal by measuring the channel quality of the CSI-RS received on the CC of the terminal; the terminal may determine the channel measurement result corresponding to the power aggregation mode based on the channel measurement result of the CSI-RS received on the CC of the terminal and the power aggregation resources indicated by the power aggregation mode. Specifically, when the signal power can be over-transmitted, the terminal may take the over-transmission amount of the signal power into account when determining the channel measurement result corresponding to the power aggregation mode based on the channel measurement result of the CSI-RS received on the CC of the terminal and the power aggregation resources indicated by the power aggregation mode, thereby improving the measurement accuracy of the channel measurement result corresponding to the power aggregation mode.

[0209] 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).

[0210] As an example, after determining the channel measurement results corresponding to each power aggregation mode, the terminal may determine a first power aggregation mode in at least one power aggregation mode based on the channel quality measurement results. The first power aggregation resource may be part of the frequency domain resources in the CC of the terminal, or the first power aggregation resource may be 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.

[0211] As an example, a channel measurement result of a signal received on the first power aggregation resource meets a channel quality threshold. For example, a CQI of a signal received on the first power aggregation resource is greater than a CQI threshold.

[0212] As an example, if at least one power aggregation mode is predefined by a protocol, the terminal can directly execute S502 and S503 without executing S501 to save signaling loss. For example, based on the at least one predefined power aggregation mode, the terminal can determine the channel quality corresponding to each power aggregation mode using the default measurement configuration information for channel measurement. In some embodiments, the measurement configuration information for channel measurement can also be predefined by a protocol or preconfigured in the terminal in advance, which is not limited here.

[0213] S503: The terminal sends first information to the network device.

[0214] In this embodiment, after determining the first power aggregation mode, the terminal may send the first information to the network device. For example, the terminal may determine a reporting method based on the measurement reporting configuration, thereby reporting the first information to the network device.

[0215] As an example, the first information may include an index of the first power aggregation mode and / or a channel measurement result of a signal received on the first power aggregation resource. Accordingly, the network device may receive the first information and determine the first power aggregation mode based on the first information, thereby determining the first power aggregation resource.

[0216] As an example, the first information may include a channel measurement result corresponding to each power aggregation mode in at least one power aggregation mode. After receiving the first information, the network device may, based on the channel measurement results corresponding to each power aggregation mode, determine the power aggregation mode corresponding to the channel measurement result that meets the channel quality threshold as the first power aggregation mode, thereby determining the first power aggregation resource.

[0217] As an example, the first information may include indication information of whether each power aggregation mode in at least one power aggregation mode can perform signal power over-transmission and / or the amount of over-transmission when each power aggregation mode performs signal power over-transmission.

[0218] As an example, after receiving the first information, the network device may also determine the first power aggregation mode based on information such as the capability of the terminal, which is not specifically limited here.

[0219] As an example, the terminal may report through a physical uplink control channel (PUCCH), or may report through uplink control information (UCI), or a media access control-control element (MAC-CE), or RRC signaling.

[0220] In this embodiment, the network device can predefine at least one power convergence mode, the terminal can measure the channel quality corresponding to each power convergence mode, and send a first information to the network device. The first information can include the index of the first power convergence mode and / or the channel measurement result corresponding to the first power convergence mode, so that the network device can configure the corresponding power convergence scheme based on the first power convergence mode or configure downlink transmission information for the terminal. In the method provided in this embodiment, the network device can determine the first power convergence mode from at least one power convergence mode based on the channel measurement result feedback of the terminal, and concentrate the radio frequency power on the first power convergence resource indicated by the first power convergence mode, and the first power convergence 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 can also be over-transmitted according to actual needs, so that the data rate of the terminal can be better improved. Radio frequency power can be understood as the power of the signal sent by the network device to the terminal.

[0221] In some application scenarios, the network device may initiate power convergence after receiving a request message from the terminal. For example, when a user attempts to watch video content using a terminal, but the terminal's current download rate is insufficient to support smooth playback of the video content, the terminal may send a request message to the network device to trigger power convergence, thereby enabling the terminal to obtain higher transmission power or better signal quality to meet its quality of service requirements. Therefore, the method in Figure 5 may also include S510. For example, before executing S501, that is, before the network device sends the second message to the terminal, S510 is executed.

[0222] S510: The terminal sends third information to the network device, where the third information is used to request power aggregation.

[0223] In this embodiment, when the terminal's downlink transmission rate or channel quality fails to meet quality of service requirements, a third message may be sent to the network device to request the network device to initiate power aggregation, thereby improving the terminal's downlink transmission rate or channel quality. Accordingly, the network device may receive the third message.

[0224] As an example, the terminal may send the third information through UCI, MAC-CE or RRC signaling.

[0225] In some implementations, the terminal may further send fourth information to the network device, where the fourth information indicates a power aggregation mode supported by the terminal. Accordingly, the network device may receive the fourth information.

[0226] As an example, the fourth information may include an index of a power aggregation mode supported by the terminal. The power aggregation mode supported by the terminal may be a power aggregation mode autonomously determined by the terminal. For example, the terminal may determine a power aggregation mode to be measured from at least one power aggregation mode and send the fourth information to the network device.

[0227] In some embodiments, the fourth information may also include the cell requested for measurement and / or the beam requested for measurement, so that the network device can configure the measurement method and / or reporting method of the channel measurement results for the terminal based on the fourth information.

[0228] As an example, the third information and the fourth information may be carried in the same message and sent, or may be carried in different messages and sent, which is not limited here.

[0229] It should be understood that the network device may execute S501 after receiving the third information or the fourth information, thereby configuring at least one power aggregation mode for the terminal.

[0230] In this embodiment, the network device may initiate power aggregation after receiving a request sent by the terminal, thereby effectively improving the data transmission rate of the terminal and meeting the quality of service requirement of the terminal.

[0231] The present application provides a more advanced and flexible power convergence method / mechanism. In the technical solution provided by the present application, at least one power convergence mode can be predefined, or the network device can configure at least one power convergence mode for the terminal, so that the terminal can determine the channel measurement result corresponding to each power convergence mode in at least one power convergence mode, and determine the first power convergence mode from at least one power convergence mode based on the channel measurement result corresponding to each power convergence mode. In addition, the terminal can evaluate the potential impact of different power convergence modes on the data rate of the terminal, such as evaluating whether each power convergence mode can over-transmit signal power. The terminal can report the determined first power convergence mode to the network device, so that the network device can adjust the power allocation strategy more accurately according to the information reported by the terminal, and can also achieve a certain degree of over-transmission 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, a terminal can determine a first power aggregation mode based on its own channel conditions and report it to a network device, so that the power allocation strategy configured by the network device for the terminal better meets the terminal's needs, achieving personalized optimization of the terminal. The network device can more effectively allocate radio frequency resources based on the terminal's reported information, improving spectrum utilization. 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 service quality optimization, and ultimately promotes improved performance of the entire wireless communication network.
