Detailed Description
In the prior art, before sending uplink data to a network device, a terminal device may report an uplink data amount that the terminal device needs to send to the network device, and meanwhile, may also report an uplink power condition of the terminal device to the network device, and after receiving the uplink data amount and the uplink power condition reported by the terminal device, the network device may allocate an uplink resource to the terminal device according to the uplink power condition, so that the terminal device may send the uplink data to the network device based on the uplink resource.
Generally, the uplink power reported by the terminal device is generally related to the downlink path loss and the power adjustment factor of the network device, and may be specifically expressed as the following formula:
ulpower＝X+A*pathloss；
in the embodiment of the present invention, X may be regarded as a constant, a is a power adjustment factor, and pathloss is a downlink path loss of the network device, and may be specifically equal to a difference between a reference signal power (which may be denoted as Rs _ power) of the network device and a received signal power of the terminal device.
In practical applications, due to the power limitation of the terminal device, the terminal device needs to transmit uplink data with limited uplink power, and therefore, the terminal device usually has the maximum uplink power. When the network device allocates the uplink resource to the terminal device, the network device may allocate the uplink resource according to a difference between the uplink power reported by the terminal device and the maximum uplink power of the terminal device. Specifically, if the uplink power reported by the terminal device is better, that is, the difference between the uplink power reported by the terminal device and the maximum uplink power of the terminal device is larger, the network device may allocate more uplink resources to the terminal device, and otherwise, the network device may not allocate enough uplink resources to the terminal device.
However, in the actual communication process, when the terminal device is located in an area with weak network coverage signals, the downlink path loss of the network device is large, and if the power adjustment factor configured by the network device is also large at this time, based on the above-mentioned formula of the uplink power, it can be known that the uplink power reported by the terminal device is also large, and the maximum uplink power of the terminal device is easily reached. Under the condition, the network device cannot allocate enough uplink resources to the terminal device, so that the terminal device cannot send uplink data to the network device, the network speed of the terminal device is slower and slower, and even the network device cannot surf the internet, thereby seriously affecting the normal communication between the terminal device and the network device.
In order to solve the above technical problem, an embodiment of the present invention provides an information reporting method and a terminal device, where the method includes: receiving a reference signal power and a power adjustment factor from a network device; reducing uplink power under the condition that the reference signal power is greater than a first threshold value and the power adjustment factor is greater than a second threshold value; and reporting the reduced uplink power to the network equipment.
Therefore, after the terminal device receives the reference signal power and the power adjustment factor from the network device, when the uplink power of the terminal device is determined to be larger according to the reference signal power and the power adjustment factor, the network device can allocate enough uplink resources to the terminal device based on the reduced uplink power by reducing the uplink power and reporting the reduced uplink power to the network device, and the terminal device can send uplink data to the network device based on the enough uplink resources, so that normal communication between the terminal device and the network device is ensured.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an information reporting method according to an embodiment of the present invention. The execution subject of the embodiment may be a terminal device, and the method is as follows.
S102: a reference signal power and a power adjustment factor are received from a network device.
In S102, in the process of communicating between the terminal device and the network device, the network device may send the reference signal power and the power adjustment factor of the network device to the terminal device, so that the terminal device may determine the uplink power to be reported based on the reference signal power and the power adjustment factor.
After the network device sends the reference signal power and the power adjustment factor to the terminal device, the terminal device may receive the reference signal power and the power adjustment factor from the network device.
S104: and reducing the uplink power under the condition that the reference signal power is greater than a first threshold value and the power adjustment factor is greater than a second threshold value.
In S104, after receiving the reference signal power and the power adjustment factor, the terminal device may determine the reference signal power and the power adjustment factor to determine whether the reference signal power and the power adjustment factor are reasonable.
Specifically, the terminal device may determine whether the reference signal power is greater than a first threshold and the power adjustment factor is greater than a second threshold. The first threshold and the second threshold may be determined according to actual conditions, and are not specifically limited herein.
When the reference signal power is greater than the first threshold and the power adjustment factor is greater than the second threshold, it may be determined that the reference signal power and the power adjustment factor are unreasonable, that is, the uplink power determined based on the reference signal power and the power adjustment factor is too large, and if the terminal device reports the uplink power to the network device, the network device may not allocate sufficient uplink resources to the terminal device.
In order to avoid the above problem, in this embodiment, when the terminal device determines that the reference signal power is greater than the first threshold and the power adjustment factor is greater than the second threshold, the uplink power may be reduced to optimize the uplink power reported by the terminal device.
In this embodiment, before reducing the uplink power, the terminal device may determine whether the current uplink resource is smaller than a third threshold, and whether a variation of the current uplink data to be transmitted is larger than a fourth threshold, where the third threshold and the fourth threshold may also be determined according to an actual situation, and are not specifically limited herein.
When the current uplink resource is smaller than the third threshold and the variation of the current uplink data to be transmitted is larger than the fourth threshold, it may be further determined whether the uplink data error rate is smaller than a fifth threshold, where the fifth threshold may be determined according to an actual situation, and is not specifically limited here.
If the uplink data error rate is smaller than the fifth threshold, it may be indicated that the actual uplink power of the terminal device can satisfy the requirement of sending the uplink data, and at this time, the uplink power may be reduced.
When the terminal device reduces the uplink power, at least one of the following methods may be adopted:
the first method comprises the following steps: reducing the reference signal power;
the second method comprises the following steps: reducing the power adjustment factor;
the third method comprises the following steps: the reference signal power and the power adjustment factor are reduced.
When the reference signal power is reduced, the reference signal power received by the terminal device may be reduced by N db, where N may be determined according to an actual situation, and is not specifically limited herein.
When the power adjustment factor is reduced, the power adjustment factor received by the terminal device may be reduced by one or more levels, for example, the value range of the power adjustment factor configured by the network device is known as {0, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1}, and assuming that the power adjustment factor received by the terminal device is 0.8, the power adjustment factor may be reduced to 0.7 or 0.6, and the like.
S106: and reporting the reduced uplink power to the network equipment.
In S106, after the terminal device reduces the uplink power, the reduced uplink power may be reported to the network device.
For example, assuming that the terminal device reduces the uplink power by reducing the reference signal power and the power adjustment factor, the uplink power reported by the terminal device to the network device may be represented as:
ulpower = X + a × pathloss = X + A1 (Rs _ power1 — terminal device received signal power);
in this embodiment, X may be regarded as a constant, A1 is a reduced power adjustment factor, and Rs _ power is a reduced power of the reference signal.
In this embodiment, when reporting the reduced uplink power to the network device, the terminal device may also report the uplink data volume to be transmitted to the network device, and after receiving the uplink power and the uplink data volume to be transmitted, the network device may allocate uplink resources to the terminal device based on the reduced uplink power.
In this embodiment, after the network device allocates the uplink resource to the terminal device based on the reduced uplink power, the terminal device may send uplink data to the network device based on the uplink resource. Because the network device allocates sufficient uplink resources, the terminal device can send uplink data to the network device based on the uplink resources allocated by the network device, thereby ensuring normal communication between the terminal device and the network device.
Optionally, in the above S104, if the reference signal power is less than or equal to the first threshold, or the power adjustment factor is less than or equal to the second threshold, the terminal device may determine that the reference signal power and the power adjustment factor are reasonable, that is, the uplink power determined based on the reference signal power and the power adjustment factor is not too large, and at this time, the terminal device does not need to execute the above S106, and report the uplink power determined based on the reference signal power and the power adjustment factor to the network device.
For facilitating understanding of the technical solutions provided by the embodiments of the present invention, refer to fig. 2. Fig. 2 is a schematic flow chart of information reporting according to an embodiment of the present invention, which may specifically include the following steps:
s201: and the network equipment transmits the reference signal power and the power adjustment factor to the terminal equipment.
The network device may send the reference signal power of the network device and the power adjustment factor to the terminal device during communication with the terminal device.
S202: the terminal equipment judges whether the power of the reference signal is larger than a first threshold value or not and whether the power adjusting factor is larger than a second threshold value or not.
If the reference signal power is greater than the first threshold and the power adjustment factor is greater than the second threshold, it may be determined that the reference signal power and the power adjustment factor are not reasonable, and at this time, S203 may be performed; if the reference signal power is less than or equal to the first threshold or the power adjustment factor is less than or equal to the second threshold, it may be determined that the reference signal power and the power adjustment factor are reasonable, and at this time, S207 may be performed.
S203: and judging whether the uplink resource is smaller than a third threshold value or not and whether the variation of the uplink data to be transmitted is larger than a fourth threshold value or not.
S204: and if the uplink resource is smaller than the third threshold and the variation of the uplink data to be transmitted is larger than the fourth threshold, judging whether the error rate of the uplink data is smaller than a fifth threshold.
S205: and if the uplink data error rate is less than a fifth threshold, reducing the uplink power.
In S205, if the uplink data error rate is smaller than the fifth threshold as a result of the determination, it may be indicated that the actual uplink power of the terminal device can satisfy the requirement of transmitting uplink data, and in this case, the uplink power may be reduced.
When the uplink power is reduced, at least one of the following may be included: reducing the reference signal power; reducing the power adjustment factor.
S206: and reporting the reduced uplink power to the network equipment.
In S206, the terminal device may also report the uplink data volume to be sent to the network device.
After executing S206, S208 may be executed.
S207: and reporting the uplink power determined based on the reference signal power and the power regulation factor to the network equipment.
In S207, the terminal device may also report the uplink data volume to be sent to the network device.
After performing S207, S208 may be performed.
S208: and the network equipment allocates the uplink resource based on the uplink power reported by the terminal equipment.
After the terminal device reports the reduced uplink power to the network device, the network device may receive the uplink power reported by the terminal device, and at this time, the network device may allocate an uplink resource to the terminal device based on the uplink power reported by the terminal device.
Since the uplink power at this time is the reduced uplink power, the network device may reallocate sufficient uplink resources to the terminal device.
S209: and the terminal equipment transmits uplink data based on the uplink resources allocated by the network equipment.
Because the network device allocates sufficient uplink resources, the terminal device can send uplink data to the network device based on the uplink resources allocated by the network device, thereby ensuring normal communication between the terminal device and the network device.
According to the scheme provided by the embodiment of the invention, after the terminal equipment receives the reference signal power and the power regulating factor from the network equipment, when the uplink power of the terminal equipment is determined to be larger according to the reference signal power and the power regulating factor, the network equipment can allocate enough uplink resources to the terminal equipment based on the reduced uplink power by reducing the uplink power and reporting the reduced uplink power to the network equipment, so that the terminal equipment can send uplink data to the network equipment based on the enough uplink resources, and normal communication between the terminal equipment and the network equipment is ensured.
