Based on the example communication system, the technical scheme of the embodiment of the application is explained by taking a base station and a terminal device as examples, when the terminal device is started, the base station sends configuration information to the terminal device first to realize downlink synchronization, then the terminal device configures transmission power based on the configuration information, then random access is initiated to the base station based on the transmission power, if the access is unsuccessful, the transmission power is taken as historical transmission power, the historical transmission power is adjusted according to a specified power step length to obtain target transmission power, then random access is initiated to the base station based on the target transmission power, and the success rate of the access of the terminal device to the base station can be improved through the adjustment of the transmission power.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for adjusting transmit power disclosed in the embodiment of the present application, where the flowchart may include steps S201 to S202:
step S201: and under the condition of random access failure based on historical transmitting power, adjusting the transmitting power according to the specified power step length and the historical transmitting power to obtain the target transmitting power.
The target transmission power is greater than the historical transmission power, that is, the historical transmission power is increased by power, so that the target transmission power is obtained. In some possible embodiments, the historical transmission power may refer to a first configured transmission power or an adjusted transmission power in case of multiple unsuccessful accesses.
In a possible implementation manner, if random access fails based on historical transmission power, the terminal device adopts an adjustment means to adjust the historical transmission power, specifically, the transmission power can be adjusted according to a specified power step length and the historical transmission power, and a simple understanding is to increase one power (the specified power step length) on the basis of the historical transmission power to obtain a target transmission power, thereby improving the network access success rate of the terminal device. The specified power step is an interval value, is greater than or equal to a first threshold value, and is less than or equal to a second threshold value. For example, the first threshold may be set to 1dB and the second threshold may be set to 2.5dB, in which case the specified power step may take 1.5dB or 2 dB.
Step S202: random access is again initiated based on the target transmit power.
In a possible implementation method, after determining the target transmission power, the terminal device establishes a communication connection, that is, a random access, with the network device. Random access is a necessary process for establishing a wireless link between a terminal and a base station, and only after the random access is completed, data interoperation can be normally performed between the base station and the terminal. The terminal can implement two basic functions through random access: one is to achieve uplink synchronization with the base station. Once the uplink is out of step, the terminal can only transmit data in the physical random access channel; and secondly, applying for uplink resources. In the field of communications, random access in turn includes contention random access and non-contention random access. The contention random access is that when the base station does not know the service or state of the terminal and the terminal has to apply for uplink resource or uplink synchronization, the terminal needs to initiate the contention random access; the non-competitive random access is random access initiated by the terminal on the designated physical random access channel resource by using the designated random access lead code according to the instruction of the base station. In this application, it is not set forth in detail.
In a possible implementation manner, the random access initiated by the terminal device based on the target transmission power may not be successful, and in this case, the target transmission power may be used as a historical transmission power, and the adjustment of the transmission power according to the specified power step length and the historical transmission power may be performed again to obtain the target transmission power, that is, an iterative process, which continuously superimposes the transmission power, thereby improving the success rate of the terminal device accessing the network device.
Further, it is necessary to determine whether the value of the target transmission power is too large, which may cause cell interference and affect normal communication. Therefore, after the target transmitting power is determined, whether the target transmitting power is larger than the reference power is judged, and if the target transmitting power is smaller than the reference power, the random access is triggered and executed again based on the target transmitting power; if the target transmitting power is greater than or equal to the reference power, deleting the target transmitting power, namely ending the random access process, and considering that the terminal equipment is unsuccessfully accessed, a conclusion can be drawn that the unsuccessfully accessed is not due to the power problem and possibly the hardware of the terminal equipment has a problem, such as the mobile phone is stopped. The reference power is determined according to configuration information received by the terminal device, and specifically includes: the terminal device receives configuration information sent by the network device, the configuration information includes reference power, the terminal device analyzes the configuration information to obtain the reference power, the configuration information can be understood as various parameters, one parameter is the reference power, and for the terminal device, the terminal device needs to analyze and read the parameter to determine the reference power.
According to the method and the device, under the condition that random access fails based on historical transmitting power, the transmitting power is adjusted according to the specified power step length and the historical transmitting power to obtain target transmitting power, and random access is initiated again based on the target transmitting power; based on the method, if the terminal equipment is unsuccessfully accessed for the first time, the transmitting power can be continuously increased, so that the success rate of accessing the terminal equipment to the network equipment is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of another method for adjusting transmission power disclosed in the embodiment of the present application, where the flow chart may include steps S301 to S309, which mainly describe what conditions need to adjust transmission power and how the terminal device adjusts transmission power when the power is too large:
step S301: and receiving configuration information sent by the network equipment, wherein the configuration information comprises received power and compensation power, and performing power compensation on the received power based on the compensation power to obtain the received power after power compensation.
In a possible implementation manner, after the terminal device is turned on for the first time or restarted, the terminal device receives configuration information sent by the network device first, where the configuration information may specifically include received power and compensation power, and the compensation power may refer to a specific value or may refer to an expression.
In a possible implementation manner, after receiving the received power, the terminal device performs power compensation on the received power based on the compensation power, where the compensation manner may be direct addition, or may be adding the compensation power to the received power after multiplying the compensation power by a coefficient to obtain the compensated received power.
Step S302: and judging whether the received power after the power compensation is larger than or equal to a set threshold value.
If the power compensated received power is greater than or equal to the set threshold, step S304 is executed, and if the power compensated received power is less than the set threshold, step S303 is executed. The set threshold may have a value range, which is not limited herein.
Specifically, when the power compensated received power is greater than or equal to the set threshold, the transmission power of the network device may be considered to be abnormal. In this application, the transmission power abnormality of the network device may include two scenarios: 1. the meter test, especially, some meters can be configured to be tested in the existing network, and the power is fixed, that is, the power of the meter configuration is too high, so that the transmission power of the network device is too large; 2. for extreme environments, such as desert regions, or areas where the initial value of the base station power needs to be set high, this may also result in excessive transmission power of the network device.
Step S303: and determining the transmitting power according to the configuration information, and initiating random access.
This situation indicates that the transmission power of the network device is normal, and the terminal device can directly perform configuration according to the configuration information issued by the network device, so as to determine the transmission power of the terminal device and initiate random access based on the configuration information.
Step S304: and determining initial transmitting power according to the power adjustment strategy.
In a possible implementation manner, when the received power after the power compensation is greater than or equal to the set threshold, the terminal device may give up the instruction issued by the network device, so as to perform conservative processing, that is, determine an initial transmit power according to the power adjustment policy of the terminal device, where the initial transmit power is a small power in general. The power adjustment policy may be determined according to types of different terminal devices, and is set when the terminal device leaves a factory. It can be understood that the initial transmit power is the same for the same type of terminal device in this case.
Step S305: random access is initiated based on the initial transmit power.
Specifically, the terminal device may initiate random access to the network device based on the initial transmit power. For the processes of steps S301 to S302 and then steps S304 to S305, an example is described, for example, in a communication system (a communication system of a base station and terminals), the base station first sets a nominal power P0 (different nominal powers for PUSCH (physical uplink shared channel) and PUCCH (physical uplink control information), denoted as P0_ PUSCH and P0_ PUCCH) for all terminals in a cell corresponding to the base station, and the value is broadcasted to all terminals through system messages; the value of P0_ PUSCH is typically (-126, 24) dBm. On the basis of the nominal power, the terminal also needs to automatically perform power compensation according to the measured path loss data, the terminal calculates the downlink path loss by measuring the downlink reference signal, and the downlink path loss is multiplied by a compensation coefficient alpha to be used as uplink path loss compensation, wherein the coefficient alpha can be present in a system message. If the power after the compensation is added to the nominal power and is still larger than the set threshold, the transmission power of the base station is considered to be abnormal (or the base station is set to be abnormal), and under the condition, the terminal adopts conservative treatment, namely, random access is initiated to the base station by a small limited power.
Step S306: and judging whether the random access is successful.
If the result is successful, the process is ended, and if the result is failed, step S307 is executed.
Step S307: and adjusting the transmitting power according to the specified power step length to obtain the target transmitting power.
In general, in the case of a failure of random access based on initial transmission power, the initial transmission power may be determined as historical transmission power, and the transmission power is adjusted according to a specified power step and the historical transmission power to obtain a target transmission power, where the target transmission power is greater than the historical transmission power.
Step S308: and judging whether the target transmitting power is larger than or equal to the reference power.
If the target transmitting power is greater than or equal to the reference power, ending the process; if the target transmission power is less than the reference power, step S309 is executed.
Step S309: random access is initiated based on the target transmit power.
Step S310: and judging whether the random access is successful.
If the access is successful, the process is ended; if the access is unsuccessful, step S307 is executed, thereby performing a loop. In each circulation, the target transmitting power is obtained by adjusting the previous transmitting power, so that the success rate of access is improved.
In the embodiment of the application, mainly stated, when the power is abnormal, the terminal device firstly determines the initial transmitting power according to a power adjustment strategy and starts random access, if the random access fails, the power adjustment is performed on the initial transmitting power according to a specified power step length, the random access is started again, if the random access fails, the random access is performed again, the adjustment is performed again, and the success of the access is ensured as far as possible within a reference power range.
