Referring to fig. 1, a block diagram of a user equipment 10 applied in the embodiment of the present application is shown. The user equipment 10 in fig. 1 comprises a processor 11, a memory 12 and a communication interface 13.

The processor 11 may include one or more processing cores, and the processor 11 connects the various components throughout the user equipment 10 using various interfaces and lines to perform various functions of the terminal 10 and process data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 12, and invoking data stored in the memory 12. Alternatively, the processor 11 may be implemented in hardware using at least one of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA).

The processor 11 may integrate one or a combination of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may be implemented by a communication chip without being integrated into the processor 11.

The Memory 12 may include a Random Access Memory (RAM) or a Read-Only Memory (Read-Only Memory). Optionally, the memory 12 includes a non-transitory computer readable medium. The memory 12 may be used to store instructions, programs, code, sets of codes, or sets of instructions. The memory 12 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playing function, an image playing function, and the like), instructions for implementing various method embodiments described below, and the like, and the operating system may be an Android (Android) system (including a system based on Android system depth development), an IOS system developed by apple, company (including a system based on IOS system depth development), or other systems.

The communication interface 13 is used to support communication connection of the user equipment 10 with external devices for data exchange between the user equipment 10 and the external devices. The embodiment of the present application does not limit the specific form of the communication connection, for example, the user equipment 10 may connect to the communication base station through the communication interface 13; or the communication interface 13 may also support the connection between the user equipment 10 and an external device through Wi-Fi or bluetooth, etc. to exchange data.

The following takes the user equipment as a mobile phone as an example, and details the problems in the related art are illustrated.

In the related art, wireless communication system products such as mobile phones generally adopt a fixed operating mode, that is, in order to balance between communication quality and power consumption, the mobile phone needs to maintain a balanced and stable connection with a network device for a long time. The communication mode can meet the requirements of users on basic communication functions, but in some scenes, for example, when file transmission is performed, the bandwidth is higher, and the conventional working mode may not meet the requirements of users, so that the transmission speed is lower, and the user experience is influenced. In addition, in idle periods such as night, the requirement on the network is low, and only basic functions such as conversation need to be guaranteed. However, in this operation manner in the related art, the fixed operation mode is always maintained during an idle period, which wastes communication resources and increases power consumption of the mobile phone.

For this situation, in some related technologies, two operation modes, namely a normal operation mode and an idle mode, are defined for the terminal device, and the operation mode is switched according to the requirement of the wireless communication system and the time period information. For example, during the day, a normal operation mode is set to ensure the communication quality; and is set to an idle mode at night to minimize power consumption.

However, with the progress of technology, the functions of the cellular phone are not limited to the conventional functions of making a call, sending a short message, and the like. In the course of daily use, there are also a variety of scenes such as online games, video chatting, browsing web pages, file transfer, and the like.

The requirements for wireless communication systems are different in different scenarios. Specifically, in the scene of an online game, the method is sensitive to the reliability, the error rate, the delay and the like of data transmission, but an extreme data transmission rate is not pursued within the allowable range of the data bandwidth; under the scenes of real-time video or image communication such as video chat, AR/VR and the like, the requirements on the reliability and delay of data transmission are high, and the user experience can be greatly influenced by the pause in the data transmission process; under the scenes of browsing webpages or APPs and other conventional daily applications, the requirements on data transmission are neutral, medium and low transmission rates are required, and no special requirement is made on the error rate; under the scene of ultra-large file transmission, the requirement on the limited data transmission rate is highest, and the instantaneous error rate, bandwidth volatility, delay and the like in the transmission process are not required to be too high; in a long standby time scenario, the data transmission rate, the error rate, the delay and the like are not sensitive, and the power consumption of the wireless communication system when the mobile phone is in standby has a great influence on the standby time of the mobile phone, so that ultra-low power consumption is to be realized in the scenario.

Referring to fig. 2, the radar chart in fig. 2 illustrates the requirements for the key performance indicators of the communication system in the different application scenarios described above. The performance indicators in fig. 2 include data transmission bandwidth, data transmission bandwidth stability, data transmission delay, data transmission error rate, and power consumption of data transmission. It should be understood that the performance indexes listed here are only examples, and in practical applications, other more indexes may be included, and this is not specifically limited in the embodiments of the present application. Table 1 below shows the specific requirements for the performance indexes described above under different application scenarios shown in fig. 2.

TABLE 1

As can be seen from fig. 2 and table 1, in different application scenarios, different requirements are respectively imposed on the wireless communication systems, but in the foregoing related art solutions, the performance indexes of the multiple scenarios are not optimized in a targeted manner, the control on the wireless communication system is not fine enough, and meanwhile, the balance between the communication performance and the energy consumption index is not achieved, which reduces the user experience.

In view of the above, the present invention provides a communication method, and details of the communication method and apparatus provided in the present invention are described below with reference to the accompanying drawings.

Fig. 3 is a schematic flowchart of a communication method provided in an embodiment of the present application, where the communication method is applied to a user equipment. It should be understood that the user equipment to which the method of the embodiments of the present application is applied may be any one of the user equipment described above.

The method in FIG. 3 includes steps S31-S32.

In step S31, target demand level information on a plurality of performance indicators of wireless communication that match an application scenario of a user device is determined according to application information of a target application running on the user device.

The target application program is an application program in a running state in the user equipment. In the embodiment of the present application, the application programs in the running state may include an application program running in the foreground and an application program running in the background. The target application program may be one or more, and the embodiment of the present application is not limited to this.

The application information of the target application may include, for example, a name of the target application, an APP ID of the target application, a type of the target application, and the like, which is not specifically limited herein.

In this embodiment of the present application, each performance indicator of a target application has a quantization level, and a set of quantization levels corresponding to a plurality of performance indicators is the target demand level information.

For all applications, a first data set may be stored as shown in table 2 below, where table 2 shows the quantitative rating of a first number of applications with respect to a plurality of performance indicators as described above. Wherein the first number may be, for example, the number of all application programs in the application store. The parameters (a1, …, a5, …; b1, …, b5, …; c1, …, c5, …) in table 2 are the quantization levels of each performance indicator corresponding to each application.

According to the quantization levels of each application program in table 2 about each performance index, the target demand level information corresponding to the target application program can be determined. For example, when the target application is application a, the corresponding target demand level information may be determined from table 2 as: [ a1, a2, a3, a4, a5 … ].

TABLE 2

In practical applications, storing the table shown in table 2 may require a huge memory space for all applications that the user device may be installed, considering the number of application programs, and may even exceed the memory space inside the user device. However, the number of applications that a single user device may have installed is often limited, meaning that for a single user device, the applications that actually apply to are typically only a very small subset of the list of applications shown in table 2.

Thus, in some embodiments, the storage and application of table 2 may be implemented in the form of a server-side (or cloud-side) -client to reduce hardware overhead in the user device.

Specifically, referring to fig. 4, the target requirement level information for determining a plurality of performance indicators related to wireless communication matching with the application scenario of the ue may be: the requirement levels of all the application programs related to the multiple performance indexes of the wireless communication system shown in table 2 are stored in the server side, and after receiving the application information of the target application program sent by the user equipment, the server side sends the requirement level of each performance index corresponding to the application program to the user equipment side. The user equipment may determine the target demand level information based on receiving a plurality of demand levels.

In some embodiments, determining the target demand level information for the plurality of performance indicators for wireless communication that matches the application scenario of the user equipment may further be: the target demand level information is obtained from a second data set stored in a storage unit of the user equipment, the second data set is shown in table 3, and the application information and the corresponding multiple demand levels of a second number of applications installed in the user equipment are listed in table 3. Wherein the second number is the number of applications already installed in the user equipment.

TABLE 3

It is clear that table 3 is a subset of table 2, and the data size shown in table 3 is much smaller than table 2. Since the user equipment only needs to store all the data in table 3, the storage space is greatly released.

In this embodiment of the application, the second data set shown in table 3 may be obtained from the first data set shown in table 2, that is, according to the application information of the second number of application programs installed in the user equipment, the corresponding demand level is obtained from the server side and stored in the storage unit of the user equipment. Alternatively, the table 3 may be pre-stored in the storage unit of the user equipment, and is not required to be obtained through the server.

In some embodiments, after determining the requirement level information corresponding to the target application, the user equipment may load the requirement level information data into a running storage space (e.g., a RAM) so that the wireless communication module can read the requirement level information from the RAM.

The method can minimize the consumption of the running storage space of the mobile phone, and only needs to add or delete data in the RAM when a new application is started or closed every time, namely, a data set shown in the table 4 is maintained in the RAM of the user equipment at the moment.

TABLE 4

As another embodiment, the user equipment may also load the second data set shown in table 3 into the RAM in its entirety. Therefore, the requirement grade information corresponding to the application program can be directly read from the RAM according to the application program currently running in the foreground. This approach takes up more memory space, but has the advantage that no special maintenance (addition or deletion) of the data loaded into the RAM is required each time a new application is started and shut down.

In step S32, based on the target demand level information, adjusting an operating parameter of a wireless communication module in the user equipment so that the adjusted operating mode of the wireless communication module matches the target demand level information.

In some embodiments, the wireless communication module may be any one of a Modem (Modem), a wireless fidelity (WIFI) communication module, and a bluetooth module.

As described above, the target requirement level information is a requirement level that matches an application scenario of the user equipment to a corresponding plurality of performance indicators regarding the wireless communication system. Wherein the performance indicator may include at least one of a data transmission bandwidth, a data transmission bandwidth stability, a data transmission delay, a data transmission error rate, and a power consumption of data transmission. That is, the wireless communication module needs to be able to provide multiple operation modes capable of meeting different requirement levels of different applications according to all the performance indexes.

The following takes an example in which the wireless communication module is a Modem, and the method for adjusting the performance indexes is described in detail.

First, data transmission bandwidth

The data transmission bandwidth includes an uplink data transmission bandwidth and a downlink data transmission bandwidth, and the adjustment of the uplink data transmission bandwidth can include the following methods within the range allowed by the Modem capability and the related standard specification (for example, the third generation partnership project 3GPP protocol), and satisfying the basic communication function:

1. and adjusting the uplink MIMO layer number reported to the base station and supported by the Modem: increasing the number of MIMO layers reported to the base station correspondingly increases the uplink data transmission bandwidth, and decreasing the number of MIMO layers correspondingly decreases the uplink data transmission bandwidth.

2. Adjusting the uplink maximum carrier aggregation number which is reported to the base station and supported by the Modem: and the uplink data transmission bandwidth is correspondingly increased by increasing the uplink maximum carrier aggregation number supported by the Modem and reported to the base station, and the uplink data transmission bandwidth is correspondingly reduced by decreasing the uplink maximum carrier aggregation number supported by the Modem and reported to the base station.

3. Adjusting the maximum frequency domain bandwidth of the uplink single carrier supported by the Modem, which is reported to the base station: and the uplink data transmission bandwidth is correspondingly increased by increasing the uplink single carrier maximum frequency domain bandwidth supported by the Modem and reported to the base station, and is correspondingly reduced by decreasing the uplink single carrier maximum frequency domain bandwidth supported by the Modem and reported to the base station.

The adjustment of the downlink data transmission bandwidth may include the following methods:

1. and adjusting the number of downlink MIMO layers reported to the base station and supported by the Modem: increasing the number of MIMO layers reported to the base station correspondingly increases the downlink data transmission bandwidth, and decreasing the number of MIMO layers correspondingly decreases the downlink data transmission bandwidth.

2. Adjusting the maximum downlink carrier aggregation number reported to the base station and supported by the Modem: and the downlink data transmission bandwidth is correspondingly increased by increasing the downlink maximum carrier aggregation number supported by the Modem and reported to the base station, and the downlink data transmission bandwidth is correspondingly reduced by decreasing the downlink maximum carrier aggregation number supported by the Modem and reported to the base station.

3. Adjusting the maximum frequency domain bandwidth of the downlink single carrier supported by the Modem, which is reported to the base station: and the downlink data transmission bandwidth is correspondingly increased by increasing the downlink single carrier maximum frequency domain bandwidth supported by the Modem and reported to the base station, and is correspondingly reduced by decreasing the downlink single carrier maximum frequency domain bandwidth supported by the Modem and reported to the base station.

4. Adjusting the reported information of the CQI, RI and other physical layers reported to the base station: the reported information of the physical layer such as CQI, RI and the like reported to the base station is moderately increased, so that the data modulation amount of the base station to a downlink channel can be increased to a certain extent, and the transmission bandwidth of downlink data is correspondingly increased; the reported information of the physical layer such as CQI, RI and the like reported to the base station is properly reduced, the data modulation amount of the base station to a downlink channel can be reduced to a certain extent, and the transmission bandwidth of downlink data is correspondingly reduced.

Second, data transmission bandwidth stability

Similarly, the stability of the data transmission bandwidth also includes the stability of the uplink and downlink data transmission bandwidths, and the adjustment of the stability of the uplink data transmission bandwidth may include the following methods:

1. adjusting the transmission power of the uplink transmission signal: the stability of the uplink data transmission bandwidth is enhanced correspondingly by the uplink transmitting power, and the stability of the uplink data transmission bandwidth is reduced correspondingly by the uplink transmitting power.

2. Adjusting the transmission quality of the uplink transmission signal: the time domain/frequency domain windowing, filtering, compensating and other algorithms with better performance are adopted, the performance of the transmitted signal is improved, and the stability of the uplink data transmission bandwidth is correspondingly improved. The stability of the uplink data transmission bandwidth is correspondingly reduced by adopting time domain/frequency domain windowing, filtering, compensating and other algorithms with slightly poor performance or not adopting the methods for improving the quality of the transmitting signal.

3. And adjusting a demodulation decoding algorithm of the downlink PDCCH signal: adopting a demodulation algorithm or parameter with better performance, such as a higher-performance algorithm for symbol-level processing, a receiver module for channel estimation, equalization and the like; for bit-level decoding processing, such as increasing the number of iterative decoding of Viterbi (Viterbi) and Polar codes, increasing the number of survivor paths in the decoding process, and the like, to improve the probability of correct detection of the PDCCH, the probability of false detection and missed detection of the PDCCH including uplink scheduling information can be reduced to a certain extent, and the stability of the uplink data transmission bandwidth is correspondingly improved. On the contrary, for the symbol-level processing, for the receiver modules such as channel estimation, equalization and the like, an algorithm with slightly lower performance is adopted; for bit-level decoding processing, for example, reducing the number of iterative decoding of Viterbi (Viterbi) and Polar codes, reducing the number of survivor paths in the decoding process, and the like, the probability of false detection and missed detection of uplink scheduling information is reduced to a certain extent, and the stability of uplink data transmission bandwidth is correspondingly reduced.

The adjustment of the downlink data transmission bandwidth stability may include the following methods:

1. adjusting the quality of the downlink received digital signal: the time domain/frequency domain windowing, filtering, compensating, interference eliminating and other algorithms with better performance are adopted, so that the performance of receiving signals is improved, and the stability of downlink data transmission bandwidth is correspondingly improved. The stability of the downlink data transmission bandwidth is correspondingly reduced by adopting time domain/frequency domain windowing, filtering, compensating, interference eliminating and other algorithms with slightly poor performance or not adopting the methods for improving the quality of the transmitted signal.

2. Adjusting a downlink signal receiver algorithm: adopting a demodulation algorithm or parameter with better performance, such as a higher-performance algorithm for symbol-level processing, a receiver module for channel estimation, equalization and the like; for bit-level decoding processing, for example, for coding types requiring iterative decoding, such as Turbo in 4G, Low Density Parity Check Code (LDPC) in 5G, and the like, the stability of downlink data transmission bandwidth is correspondingly improved by adopting more iterative decoding times and the like. Otherwise, a demodulation algorithm or parameter with slightly poor performance or fewer iterative decoding times is adopted, and the stability of the downlink data transmission bandwidth is correspondingly reduced.

3. Adjusting bit width in the downlink signal processing process: increasing the bit width in the downlink signal processing procedure correspondingly improves the stability of the downlink data transmission bandwidth, and decreasing the bit width in the downlink signal processing procedure correspondingly reduces the stability of the downlink data transmission bandwidth.

Third, data transmission delay

For the adjustment of the uplink data transmission delay, within the range allowed by the Modem capability and the allowed range of the relevant standard specification (for example, the third generation partnership project 3GPP protocol), and on the premise of satisfying the basic communication function, the following methods can be included:

1. and adjusting the uplink processing capacity of the Modem reported to the base station: taking 5G as an example, if the Modem reports and supports "PUSCH processing capability level 2" (UE capability definition item in 3GPP 38.331: featureuplink:: PUSCH-processing type2) ", the uplink data transmission delay is lower; and if the Modem report does not support the PUSCH processing capability level 2, the method corresponds to slightly higher uplink data transmission delay.

2. Adjusting the bandwidth of uplink subcarriers reported to the Modem of the base station: taking 5G as an example, the Modem reports a Sub-Carrier Spacing (SCS) supporting a larger subcarrier bandwidth, so that the time duration of each slot is shorter, corresponding to a lower uplink data transmission delay; conversely, the Modem only supports a smaller subcarrier bandwidth, so that the time domain duration of each slot is longer, corresponding to a higher uplink data transmission delay.

3. Adjusting the maximum PUSCH transmission number supported by each slot of the uplink of the Modem reported to the base station: for example, taking 5G as an example, for "PUSCH processing capability level 1 (UE capability definition item: featureuplink:: PUSCH-processing type 1-differential tb-slot" in 3GPP 38.331), the UE may report that each slot supports PUSCH transmission for different times, such as 2 times, 4 times, 7 times, and the like, for each SCS. For "PUSCH processing capability level 2 (UE capability definition item in 3GPP 38.331: featureuplink:: PUSCH-processing type 2)", the UE may report that each slot supports PUSCH transmission for different times, such as 1 time, 2 times, 4 times, 7 times, etc., for each SCS. For each processing capability grade, the larger SCS, the more times of PUSCH transmission supported by each slot, the smaller the minimum time granularity corresponding to single PUSCH transmission, and the lower uplink transmission delay; conversely, for each processing capability level, the smaller SCS and the smaller number of PUSCH transmissions supported by each slot are, the larger the minimum time granularity of the corresponding secondary PUSCH transmission is, the higher the uplink data transmission delay is.

For downlink data transmission delay, the method provided by the embodiment of the application comprises the following steps:

1. and (3) adjusting the downlink processing capability of the Modem reported to the base station: taking 5G as an example, if the Modem reports and supports "PDSCH processing capability level 2" (UE capability definition item in 3GPP 38.331: featuredownlink:: PDSCH-processing type2) ", the downlink data transmission delay is lower; and the Modem does not support the PDSCH processing capability level 2, and the method corresponds to slightly higher downlink data transmission delay.

2. And adjusting the bandwidth of the downlink subcarrier reported to the Modem of the base station: taking 5G as an example, if the Modem reports that a larger subcarrier bandwidth is supported, the time domain duration of each slot is smaller, and the lower downlink data transmission delay is corresponded to; on the contrary, the Modem only supports a smaller subcarrier bandwidth, so that the time domain duration of each slot is longer, and higher uplink and downlink data transmission delay is correspondingly realized.

3. Adjusting the maximum number of PDSCH transmissions supported by each slot of the downlink of the Modem reported to the base station: taking 5G as an example, for "PDSCH processing capability level 1 (UE capability definition item in 3GPP 38.331: featuretoppk:: pusch-processing type 1-differential tb-Perslot)", the UE may report that each slot supports PDSCH transmission for different times, such as 2 times, 4 times, 7 times, etc., for each SCS. For "PDSCH processing capability level 2 (UE capability definition item: featuredownlink:: PDSCH-processing type2 in 3GPP 38.331)", the UE may report that 1, 2, 4, 7, etc. different times of PDSCH transmission are supported per slot for each SCS. For each processing capability level, the larger SCS and the larger number of times of PDSCH transmission supported by each slot are, the smaller the minimum time granularity corresponding to single PDSCH transmission is, the lower downlink data transmission delay is corresponding to; conversely, for each processing capability level, the smaller SCS and the smaller number of PDSCH transmissions supported by each slot, the larger the minimum time granularity of the corresponding PDSCH transmission, and the higher the downlink data transmission delay.

Fourthly, data transmission error rate

For the adjustment of the uplink data transmission error rate, the optional method includes:

1. on the premise of not affecting other performance indexes, the method for adjusting the stability of the uplink data transmission bandwidth in the foregoing can also be used for adjusting the uplink data transmission error rate to a certain extent.

2. Adjusting the maximum repeated transmission times of the uplink: the reliability of the same data packet transmission can be improved by configuring uplink repeated transmission. Specifically, taking 5G uplink as an example, the UE capability definition item in the 3GPP 38.331 standard document: FeatureSetUplink-v 1610:pusch-repetition type B-r 16:maxNumberPUSCH-Tx-r 16 can be configured to 2/3/4/7/8/12 repeated transmissions. Wherein, more transmission times correspondingly reduce the transmission error rate of the uplink data with larger amplitude; and fewer transmission times correspondingly reduce the magnitude of the uplink data transmission error rate.

For adjusting the downlink transmission error rate, an optional method provided in this embodiment of the present application includes:

1. on the premise of not affecting other performance indexes, the method can also be used for adjusting the downlink data transmission error rate to a certain extent by adopting the method related to the adjustment of the downlink data transmission bandwidth stability in the preamble.

2. Downlink repeat transmission enable: the reliability of the same data packet transmission can be improved by configuring downlink repeated transmission. Specifically, taking the 5G downlink as an example, the UE capability definition item in the 3GPP 38.331 standard document: Phy-ParameterCommon:: pdsch-repetition MultiSlots can be configured as "supported". Therefore, the error rate of downlink data transmission is reduced through downlink repeated transmission. Configuring downlink repeated transmission, and correspondingly reducing the transmission error rate of downlink data; downlink repeated transmission is not configured, and the error rate of downlink data transmission is not correspondingly reduced.

Fifth, power consumption of data transmission

If the power consumption of the Modem is to be reduced, under the condition that the Modem capability is allowed and the relevant standard specification (such as 3GPP, etc.) is allowed, and the basic communication function is satisfied, alternative methods include, but are not limited to:

1. adjusting the number of uplink and/or downlink MIMO layers supported by the Modem and reported to the base station: increasing the number of MIMO layers reported to the base station, and scheduling uplink and/or downlink transmission with more MIMO layers by the corresponding base station, wherein the uplink and/or downlink transmission with more MIMO layers has higher power consumption; and the number of MIMO layers reported to the base station is reduced, the corresponding base station can schedule uplink or downlink transmission with fewer MIMO layers, and the uplink and/or downlink transmission with fewer MIMO layers has lower power consumption.

2. And adjusting the maximum carrier aggregation number of uplink and/or downlink supported by the Modem, which is reported to the base station: the maximum carrier aggregation number of uplink and/or downlink supported by the Modem and reported to the base station is increased, the corresponding base station can schedule more uplink and/or downlink carrier transmission, and more uplink and/or downlink carrier transmission corresponds to higher power consumption; and reducing the maximum uplink or downlink carrier aggregation number which is reported to the base station and supported by the Modem, wherein the corresponding base station can schedule less uplink and/or downlink carrier transmission, and the less uplink and/or downlink carrier transmission corresponds to lower power consumption.

3. And the uplink data transmission bandwidth is increased, and the maximum uplink carrier aggregation quantity reported to the base station and supported by the Modem is reduced, so that the uplink data transmission bandwidth is correspondingly reduced.

4. Adjusting the receiving and decoding iteration times of the PDCCH signals: taking PDCCH channels in 4G and 5G as examples, the number of iterative decoding is increased, and power consumption is correspondingly higher; the number of iterative decoding is reduced, and the power consumption is correspondingly lower;

5. adjusting PDSCH signal receiver algorithm: the power consumption can be adjusted by adjusting the algorithms of different computational complexity that the receiver uses, to the extent performance allows. For example, for symbol-level processing, for receiver modules such as channel estimation and equalization, an algorithm with higher computational complexity is adopted; for bit-level decoding processing, for example, for coding types requiring iterative decoding, such as Turbo in 4G, LDPC in 5G, and the like, more iterative decoding times are adopted, which corresponds to higher power consumption. On the contrary, a demodulation algorithm with slightly lower computational complexity or fewer iterative decoding times is adopted, which corresponds to higher and lower power consumption.

6. Adjusting the transmission power of the uplink transmission signal: the higher power consumption corresponding to the increased uplink transmission power; reducing the uplink transmit power corresponds to lower power consumption.

7. Adjusting bit width in the uplink and/or downlink signal processing process: increasing the power consumption corresponding to the bit width in the uplink and/or downlink signal processing process; reducing bit width pairs in the upstream and/or downstream signal processing process corresponds to lower power consumption.
