Usually, the transmit power of the terminal is related to the cell, that is, after the terminal accesses a cell, it will adjust the transmit power according to the transmit power control information broadcast or configured by the base station of the cell.

In some cases, the transmit power of the terminal is related to the location of the terminal. A typical example is shown in Figure 2. For some frequency bands, due to the need to consider coexistence with other systems such as satellites, it cannot be used outdoors or cannot be used for high-power transmission outdoors. For example, for the bandwidth (Band) X frequency band, when the terminal is in a similar confined space such as indoors/cars (such as terminal 1 in Figure 2), the terminal can transmit at high transmit power, and when the terminal is outdoors/outside the car, etc. When the space is open (such as terminal 2 in FIG. 2 ), the terminal needs to transmit with low power or the transmit power does not exceed a certain upper limit.

Based on the above problems, the present application proposes a power control solution, which can adjust the transmission power more flexibly.

The technical scheme of the present application is described in detail below through specific examples.

FIG. 3 is a schematic flowchart of a power control method 200 according to an embodiment of the present application. As shown in FIG. 3 , the power control method 200 may include at least part of the following content:

S210, the terminal device determines its supported transmit power capability according to the first information;

Among them, the first information includes but is not limited to at least one of the following:

The location information of the terminal device;

Speed information of the terminal device;

In this embodiment of the present application, the terminal device may support one or more transmission power capabilities. For example, the terminal device can support high transmit power capability or low transmit power capability. When the terminal device supports high transmit power capability, the terminal device can transmit based on high power or low power transmission; when the terminal device supports low transmit power capability , the terminal equipment can only transmit based on low power.

In some embodiments, the location information of the terminal device includes a first location or a second location, wherein the first location is located in a closed or semi-closed space, and the second location is located in an open space.

For example, when the terminal device is located in a similar confined space such as a room/compartment, the terminal device is in the first position.

For example, when the terminal device is located in an open space such as outdoors/outside the compartment, the terminal device is in the second position.

In some embodiments, when the first information includes the location information of the terminal device, the above S210 may specifically include:

When the terminal device is in the first position, the terminal device determines that it supports a first transmit power capability;

and / or,

When the terminal device is in the second position, the terminal device determines that it supports a second transmit power capability;

Wherein, the first transmit power capability is greater than the target threshold, and the second transmit power capability is smaller than the target threshold.

When the terminal device is in the first position or the second position, the terminal device determines that it supports a second transmission power capability; wherein the second transmission power capability is smaller than a target threshold.

For example, at least one base station accessed by the terminal device includes a first base station and a second base station, where the first base station is located in a closed or semi-closed space, and the second base station is located in an open space. In this case, the terminal device can receive signals from the first base station and the second base station at the same time, and when the terminal device is in the first position or the second position, the terminal device determines that it supports the second base station. A transmit power capability; wherein, the second transmit power capability is smaller than a target threshold. That is, the terminal device only uses low-power transmission in this area to ensure that the transmission power limit of the protocol or regulation can be met.

In some embodiments, the first transmit power capability may also be equal to the target threshold, or the second transmit power capability may also be equal to the target threshold. This application is not limited to this.

In some embodiments, the fact that the first transmit power capability is greater than the target threshold may be understood as: the maximum transmit power allowed by the first transmit power capability is greater than the target threshold, or the maximum power level allowed by the first transmit power capability is greater than the target threshold. Similarly, the fact that the second transmit power capability is less than the target threshold may be understood as: the maximum transmit power allowed by the second transmit power capability is less than the target threshold, or the maximum power level allowed by the second transmit power capability is less than the target threshold.

In some embodiments, the target threshold may be pre-configured or agreed upon in a protocol, or the target threshold may be configured for a network device.

It should be noted that, in order to further determine the location of the terminal equipment and its limitation on the transmission power, the spatial propagation loss can be considered to determine the location of the terminal equipment. One of the differences between terminal equipment located in the first location (such as indoors) and the second location (such as outdoors) is the large penetration loss caused by the wall (the loss value of a typical electromagnetic wave penetrating the wall is 20 decibels (dB)), The transmission power of the terminal equipment will cause great attenuation after penetrating through the wall, so that the high transmission power of the terminal at the first location (such as indoors) will not cause interference to other systems at the second location (such as outdoors) . Therefore, one way to determine the location of the terminal equipment is based on the spatial propagation loss from the base station to the terminal.

In some embodiments, the terminal device determines the location information of the terminal device according to the second information;

Wherein, the second information includes but is not limited to at least one of the following:

In some embodiments, the spatial transmission loss value between the terminal device and the first base station is greater than a second threshold, and the increase in the spatial transmission loss between the terminal device and the first base station within a first duration When the value is greater than the third threshold, the terminal device determines that it is in the second position. In this case, the terminal device may consider that it has moved from the first location (that is, indoors) to a second location (that is, outdoors), and the terminal device may be terminal 2 as shown in FIG. 4 . In this case, the terminal The device may support the second transmit power capability (for example, low transmit power capability, the terminal can only transmit with low power).

In this case, the terminal The device may support the first transmit power capability (for example, high transmit power capability, the terminal can transmit with high power).

For example, as shown in Figure 5, there is only a second base station located in an open space in an area, both terminal 1 and terminal 2 are connected to the same base station (ie, the second base station), but terminal 1 is located in the first location (such as indoor ), can transmit higher power; terminal 2 is located in a second location (such as outdoors), and can only transmit low transmit power. In this case, the terminal device may be terminal 1 or terminal 2 in FIG. 5 .

In some embodiments, if the spatial propagation loss value between the terminal device and the second base station is greater than a fifth threshold, the terminal device determines that it is at the first location. That is, when the spatial propagation loss value between the terminal device and the second base station is greater than the fifth threshold, the terminal device may be terminal 1 as shown in FIG. 5 , and in this case, the terminal device may Support the first transmit power capability (for example, high transmit power capability, the terminal can transmit with high power).

In some embodiments, the spatial propagation loss value between the terminal device and the second base station is greater than a sixth threshold, and the spatial transmission loss between the terminal device and the second base station increases within a third duration When the value is greater than the seventh threshold, the terminal device determines that it is in the first position. In this case, the terminal device may consider that it has moved from the second location (that is, outdoors) to the first location (that is, indoors), and the terminal device may be terminal 1 as shown in FIG. 5 . In this case, the terminal The device may support the first transmit power capability (for example, high transmit power capability, the terminal can transmit with high power).
