[0072] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, the same numbers refer to the same or similar elements unless otherwise represented. The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0073] A power adjustment method is provided in the embodiments of the present disclosure, which can be applied to a terminal device having multiple antennas, Figure 1 is a flowchart of a power adjustment method according to an example embodiment Figure One As shown in the figure, the method mainly includes the following steps: Figure 1

[0074] In step 101, a probe request is sent to a base station side, wherein the probe request is used to request to obtain transmission quality parameters of each transmission path corresponding to each antenna;

[0075] In step 102, the base station side returns the transmission quality parameters of each transmission path based on the probe request;

[0076] In step 103, the transmission power of each transmission path is adjusted according to the transmission quality parameters.

[0077] Here, the terminal device includes mobile terminals and fixed terminals, wherein the mobile terminals include mobile phones, tablet computers, smart home devices such as smart speakers, and the fixed terminals can include personal computer devices, monitoring devices, or medical devices, etc. The power adjustment method in the embodiments of the present disclosure is applied to a terminal device having multiple antennas.

[0078] In the embodiments of the present disclosure, during the process of power transmission of the terminal device based on the multiple antennas, a probe request can be sent to the base station side to obtain the transmission quality parameters of the transmission path corresponding to each antenna from the base station side. For example, the probe request can be sent to the base station side at a preset period, wherein the preset period can be set as needed, such as sending the probe request every 20 seconds, etc., which is not limited herein. In some other embodiments, the probe request can also be sent to the base station side in a random manner, etc. ​

[0079] In some embodiments, each antenna can correspond to a transmission channel, which can include a physical uplink shared channel (PUSCH) that can transmit both user data and control information, and the control information can include a channel quality indicator (CQI), a rank indication (RI), a precoding matrix indicator (PMI), and the like. The transmission channel can also include a physical uplink control channel (PUCCH) that can only transmit control information but not user data.

[0080] In some embodiments, the base station side can determine the transmission quality parameters of the transmission channels according to the data received from the transmission channels, and return the transmission quality parameters of the transmission channels to the terminal device after receiving the probe request. It should be noted that the terminal device can carry the device identifier of the terminal device in the probe request when sending the probe request to the base station side, so that the transmission quality parameters can be accurately sent to the corresponding terminal device when the base station side corresponds to multiple terminal devices.

[0081] In the embodiments of the present disclosure, the terminal device can adjust the transmission power of each transmission channel according to the transmission quality parameters after receiving the transmission quality parameters of each transmission channel. For example, the transmission power of the transmission channel with poor transmission quality can be scheduled to the transmission channel with good transmission quality, so that the transmission channel with good transmission quality can carry more power transmission tasks and reduce the tasks carried by the transmission channel with poor transmission quality. For another example, the transmission power of the antenna corresponding to the transmission channel with poor transmission quality can be reduced, and the transmission power of the antenna corresponding to the transmission channel with good transmission quality can be increased.

[0082] In the embodiments of the present disclosure, the terminal device can send a probe request to the base station side and accept the transmission quality parameters of each transmission channel returned by the base station side based on the probe request, and then adjust the transmission power of each transmission channel according to the transmission quality parameters. Compared with the technical solution in the related art in which each transmission channel transmits power according to the same fixed value, in the embodiments of the present disclosure, the transmission power of each transmission channel can be dynamically adjusted according to the transmission quality parameters of each transmission channel, so that the transmission power of each transmission channel can be uniformly distributed, the transmission channels can be balanced, the uplink channel can always be in a balanced state, the uplink error code situation can be reduced, and the uplink radiation capability can be improved.

[0083] In some embodiments, the adjusting the transmission power of each transmission path according to the transmission quality parameter comprises:

[0084] comparing each transmission quality parameter, and adjusting the transmission power of each transmission path according to the comparison result.

[0085] In the embodiments of the present disclosure, after obtaining the transmission quality parameter of each transmission path, the transmission quality parameter of each transmission path can be compared, and the transmission power of each transmission path can be adjusted according to the comparison result. For example, in the case of multiple transmission paths, the multiple transmission quality parameters corresponding to the multiple transmission paths can be compared with each other, for example, the transmission power of the transmission path with higher transmission quality parameter can be increased, or the transmission power of the transmission path with higher transmission quality parameter can be reduced, and the specific adjustment strategy can be set as needed, which is not limited here.

[0086] In the embodiments of the present disclosure, the transmission quality parameters of each transmission path can be compared, and the transmission power of each transmission path can be adjusted according to the comparison result. By considering the transmission quality parameters of all transmission paths, the balancing effect of the transmission power of each transmission path can be better.

[0087] In some embodiments, the adjusting the transmission power of each transmission path according to the transmission quality parameter comprises:

[0088] If the comparison result indicates that the transmission quality parameter of the first transmission path is greater than the transmission quality parameter of the second transmission path, the transmission power of the first transmission path is adjusted to be lower than the transmission power of the second transmission path.

[0089] The transmission quality parameter is negatively related to the transmission quality of the transmission path.

[0090] Here, the first transmission path and the second transmission path can be any two transmission paths in all transmission paths. It should be noted that, since the transmission quality parameter is negatively related to the transmission quality of the transmission path, when the transmission quality parameter of the first transmission path is greater than the transmission quality parameter of the second transmission path, it means that the transmission quality of the first transmission path is lower than the transmission quality of the second transmission path. In the embodiments of the present disclosure, when the transmission quality of the first transmission path is lower than the transmission quality of the second transmission path, the transmission power of the first transmission path can be adjusted to be lower than the transmission power of the second transmission path.

[0091] For example, the power adjustment value can be preset, and in the implementation process, the first transmission path can be increased by the power adjustment value based on the current transmission power, and the second transmission path can be decreased by the power adjustment value based on the current transmission power. In other embodiments, the power adjustment value increased for the first transmission path and the power adjustment value decreased for the second transmission path can be the same or different, which is not specifically limited here.

[0092] In the embodiments of the present disclosure, by adjusting the transmission power of the first transmission path to be lower than the transmission power of the second transmission path, the transmission path with better transmission quality can carry more power transmission tasks, and the transmission path with poor transmission quality can reduce the tasks to be carried, so as to achieve the effect of balancing the transmission power of each transmission path.

[0093] In some embodiments, the adjusting the transmission power of the second transmission path to be lower than the transmission power of the first transmission path comprises:

[0094] decreasing the transmission power of the first transmission path by a preset first power adjustment value, and increasing the transmission power of the second transmission path by the first power adjustment value.

[0095] The first power adjustment value is positively correlated with the difference between the transmission quality parameter of the first transmission path and the transmission quality parameter of the second transmission path.

[0096] Here, since the first power adjustment value is positively correlated with the difference between the transmission quality parameter of the first transmission path and the transmission quality parameter of the second transmission path, that is, the greater the difference between the transmission quality of the first transmission path and the transmission quality of the second transmission path, the greater the first power adjustment value, and the smaller the difference between the transmission quality of the first transmission path and the transmission quality of the second transmission path, the smaller the first power adjustment value. By correlating the first power adjustment value with the difference between the transmission quality parameter of the first transmission path and the transmission quality parameter of the second transmission path, the first power adjustment value can be dynamically determined, so that the transmission power of each transmission path is more balanced.

[0097] Here, assuming that the first transmission path is TX1, the second transmission path is TX2, and the first power adjustment value is P1, the formula of the power of the first transmission path after the transmission power is decreased by the first power adjustment value can be:

[0098] TX1 txp = TX1 txpwr - P1 (1);

[0099] In formula (1), TX1 txp represents the adjusted transmission power of the first transmission path, and TX1 txpwrdenotes the current transmission power of the first transmission path, and P1 denotes the first power adjustment value.

[0100] The formula for increasing the transmission power of the second transmission path by the first power adjustment value can be:

[0101] TX2 txp = TX2 txpwr + P1 (2).

[0102] In formula (2), TX2 txp denotes the adjusted transmission power on the second transmission path, TX2 txpwr denotes the current transmission power of the second transmission path, and P1 denotes the first power adjustment value.

[0103] That is, the terminal device can adjust the transmission power on the first transmission path from TX1 txpwr to TX1 txpwr -P1, and adjust the transmission power on the second transmission path from TX2 txpwr to TX2 txpwr + P1.

[0104] In the embodiments of the present disclosure, since the first power adjustment value is positively correlated with the difference between the transmission quality parameter of the first transmission path and the transmission quality parameter of the second transmission path, in the process of power adjustment of the terminal device, the transmission power of the first transmission path can be reduced by the first power adjustment value, and the transmission power of the second transmission path can be increased by the first power adjustment value, so that balanced transmission of the transmission power of each transmission path can be realized on the basis of ensuring that the total transmission power is unchanged, and the uplink path is always in a balanced state, the situation of uplink error code is reduced, and the uplink radiation capability is improved.

[0105] In some embodiments, the transmission quality parameter includes: a number of parsing failures when the base station side parses the data received from the terminal device; and the method further includes:

[0106] determining the first power adjustment value based on a difference between the number of parsing failures corresponding to the first transmission path and the number of parsing failures corresponding to the second transmission path;

[0107] wherein the difference is positively correlated with the first power adjustment value.

[0108] It should be noted that in the process of power transmission based on the plurality of antennas, a data packet can also be transmitted to the base station side, and the base station side will parse the received data packet after receiving the data packet. In the embodiments of the present disclosure, a counter can be set on the base station side to count the number of parsing failures when the base station side parses the data packet.

[0109] For example, the number of parsing failures corresponding to the first transmission path is TX1 CRCNum , the number of parsing failures corresponding to the second transmission path is TX2 CRCNum , then the difference between the number of parsing failures corresponding to the first transmission path and the number of parsing failures corresponding to the second transmission path can be: TX1 CRCNum -TX2 CRCNum .

[0110] In the embodiments of the present disclosure, each transmission path can be compensated differently based on the difference in the data packet parsing capability of each transmission path, the quality of the uplink transmission channel is taken into account, and the transmission power of each transmission path is adjusted.

[0111] In some embodiments, the method further comprises:

[0112] receiving the power adjustment information sent by the base station side; wherein the power adjustment information carries a preset second power adjustment value;

[0113] adjusting the transmission power of each transmission path according to the transmission quality parameter, comprising:

[0114] determining a third power adjustment value according to the transmission quality parameter and the second power adjustment value;

[0115] adjusting the transmission power of each transmission path according to the third power adjustment value.

[0116] In the embodiments of the present disclosure, after receiving the power adjustment information sent by the base station side, the second power adjustment value can be obtained from the power adjustment information, and the third power adjustment value can be determined according to the transmission quality parameter and the second power adjustment value, and then the transmission power of each transmission path can be adjusted according to the third power adjustment value.

[0117] In some embodiments, the transmission quality parameter includes the number of parsing failures when the base station side parses the data received from the terminal device; and determining the third power adjustment value according to the transmission quality parameter and the second power adjustment value comprises:

[0118] determining a first power adjustment value based on the difference between the number of parsing failures corresponding to the first transmission path and the number of parsing failures corresponding to the second transmission path; and determining the third power adjustment value according to the first power adjustment value and the second power adjustment value.

[0119] Here, assuming that the first transmission path is TX1, the second transmission path is TX2, and the first power adjustment value is P1, when the transmission quality parameter of the first transmission path is greater than the transmission quality parameter of the second transmission path, the calculation formula of the third power adjustment value determined according to the transmission quality parameter and the second power adjustment value can be:

[0120]

[0121] In formula (3), P3 represents the third power adjustment value, P2 represents the second power adjustment value, and P1 represents the first power adjustment value.

[0122] According to the third power adjustment value, the calculation formula for adjusting the transmission power of the first transmission path can be:

[0123]

[0124] In formula (4), TX1 txp represents the adjusted transmission power on the first transmission path, TX1 txpwr represents the current transmission power of the first transmission path, P2 represents the second power adjustment value, and P1 represents the first power adjustment value.

[0125] According to the third power adjustment value, the calculation formula for adjusting the transmission power of the second transmission path can be:

[0126]

[0127] In formula (5), TX2 txp represents the adjusted transmission power on the second transmission path, TX2 txpwr represents the current transmission power of the second transmission path, P2 represents the second power adjustment value, and P1 represents the first power adjustment value.

[0128] In the embodiments of the present disclosure, the terminal device can make the scheduling of each transmission path consistent with the parameters of the current base station side scheduling, and further make the scheduling of the transmission power of the base station side and the terminal device consistent. On the basis of the original transmission power allocation, the power adjustment information issued by the base station side is adjusted in a targeted manner based on the transmission quality of the path level.

[0129] The present disclosure provides a power adjustment method, which can be applied to the base station side, Figure 2 The power adjustment method according to an exemplary embodiment is shown in the flowchart Figure Two As shown in Figure 2 , the method mainly includes the following steps:

[0130] In step 201, a probe request sent by a terminal device is received; wherein the terminal device has a plurality of antennas, and the antennas correspond to transmission paths;

[0131] In step 202, based on the probe request, transmission quality parameters of each transmission path are sent to the terminal device;

The power adjustment method in the embodiments of the present disclosure is applied to a terminal device with multiple antennas.

[0134] In the process of power transmission of the terminal device based on the multiple antennas, a probe request can be sent to the base station side to obtain the transmission quality parameter of the transmission path corresponding to each antenna from the base station side. For example, the probe request can be sent to the base station side at a preset period, and the preset period can be set as needed, for example, the probe request can be sent once every 20 seconds, and the like, which is not limited herein.

[0135] In some embodiments, the base station side can determine the transmission quality parameter of each transmission path according to the data received from each transmission path, and return the transmission quality parameter of each transmission path to the terminal device after receiving the probe request. It should be noted that when the terminal device sends the probe request to the base station side, the device identifier of the terminal device can be carried in the probe request and sent to the base station side, so that when the base station side is connected to multiple terminal devices, the transmission quality parameter can be accurately sent to the corresponding terminal device.

[0136] In the embodiments of the present disclosure, after receiving the transmission quality parameter of each transmission path, the terminal device can adjust the transmission power of each transmission path according to the transmission quality parameter. For example, the transmission power of the transmission path with poor transmission quality can be scheduled to the transmission path with good transmission quality, so that the transmission path with good transmission quality can carry more power transmission tasks, and the task carried by the transmission path with poor transmission quality is reduced. For another example, the transmission power of the antenna corresponding to the transmission path with poor transmission quality can be reduced, and the transmission power of the antenna corresponding to the transmission path with good transmission quality can be increased.

[0137] In the embodiments of the present disclosure, the terminal device can send a probe request to the base station side, and accept the transmission quality parameters of each transmission path returned by the base station side based on the probe request, and then adjust the transmission power of each transmission path according to the transmission quality parameters. Compared with the technical solution in the related art that each transmission path transmits power according to the same fixed value, in the embodiments of the present disclosure, the transmission power of each transmission path can be dynamically adjusted according to the transmission quality parameters of each transmission path, so that the transmission power of each transmission path is evenly distributed, the transmission paths are balanced, the uplink is always in a balanced state, the uplink error code situation is reduced, and the uplink radiation capability is improved.

[0145] In step 301, a terminal device (User Equipment, UE) sends a probe request to a base station side, wherein the probe request is used to request to obtain transmission quality parameters of each transmission path corresponding to each antenna;
