The technical solution of the embodiment of the present invention is mainly applied to a 5G mobile communication system. Of course, the technical solution of the embodiment of the present invention is not limited to the 5G mobile communication system, and can also be applied to other types of mobile communication systems. The following describes the main application scenarios in 5G mobile communication systems:

1) eMBB scenario: eMBB targets users to obtain multimedia content, services, and data, and its business demand is growing rapidly. Because eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and its service capabilities and requirements vary widely, it is necessary to analyze services in conjunction with specific deployment scenarios.

2) URLLC scenario: Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations, and traffic safety assurance.

3) mMTC scenario: The typical characteristics of URLLC include: high connection density, small amount of data, delay-insensitive services, low cost of modules, and long service life.

In NR, the power level of the terminal is generally 23 dBm by default. In order to enable good uplink coverage at the cell edge or in an environment with poor channel conditions, the terminal supports a high power level of 26 dBm. At present, the UE supporting high power levels is an optional feature of the UE, and only supports high power levels in 4 frequency bands. In other cases, it supports the default power level, that is, the 23 dBm power level.

Considering user radiation and other factors, for a UE supporting a power level of 26 dBm, it is necessary to limit the proportion of uplink (UL, Up Link) transmission time. The proportion of the UL transmission time refers to the proportion of the UL transmission time within a predetermined time. To this end, the UE needs to report the proportion of the maximum UL transmission time supported. If the network-side scheduling exceeds the UE's ability to account for UL transmission time, the UE falls back to the default power level, such as 23 dBm.

FIG. 2 is a schematic flowchart of an information transmission method according to an embodiment of the present application. As shown in FIG. 2, the information transmission method includes the following steps:

Step 201: When the terminal determines that the power level changes, it sends a first message to the network device, where the first message includes a PHR and / or the power level of the terminal.

In the embodiment of the present application, the terminal may be any device that can communicate with a network, such as a mobile phone, a tablet computer, a notebook computer, and a desktop computer.

In the embodiment of the present application, the network device may be a base station, such as a gNB in 5G.

In the embodiment of the present application, the change in the power level of the terminal means that the power level of the terminal changes from one power level to another, for example, from the default power level (23 dBm) to a high power level (26 dBm), and then For example: change from high power level (26dBm) to the default power level (23dBm).

In the embodiment of the present application, when a power level of a terminal changes, a first message is sent to a network device, where the first message includes a PHR and / or a power level of the terminal.

Here, PHR refers to the power headroom report. The role of PHR is that the terminal reports the power headroom to the network. The value of this power headroom is through the control unit (CE, Control Element) of the Media Access Control (MAC, Media Access Control) layer. The MAC sent by) for transmitting PHR is also called the PHR control unit. The power headroom is the difference between the maximum transmission power allowed by the UE and the physical uplink shared channel (PUSCH) transmission power obtained from the current evaluation. The power headroom is in addition to the transmission power used in the current PUSCH transmission, how much transmission power the UE has available. The unit of the power headroom is dB, and the range is [-23dB, + 40dB]. If it is negative, it means that the network side has scheduled a data transmission rate higher than the data transmission rate supported by the UE at the time.

Here, the power level of the terminal corresponds to a power value, for example, the default power level is 23 dBm and the high power level is 26 dBm.

In the embodiment of the present application, when the power level of the terminal changes, the information sent to the network device through the first message has the following situations:

1) the first message includes a PHR;

2) The first message includes a PHR and a power level of the terminal; here, the power level of the terminal may be sent in the form of a PHR.

3) the first message includes a PHR, and the PHR includes a power level of the terminal;

4) The first message includes the power level of the terminal. Here, the first message is RRC signaling or MAC CE.

In the embodiment of the present application, the power level of the terminal changes, which can be implemented in the following ways:

1) The terminal adjusts a power level of the terminal based on a channel quality.

In an embodiment, in a state where the power level of the terminal is at the first power level, if it is detected that the channel quality is less than or equal to the first threshold value, the terminal triggers adjustment of the power level of the terminal to the first level. Two power levels, the second power level is greater than the first power level. Here, the first threshold value is configured by a network device, for example, the network device sends the first threshold value to the terminal through system broadcast or dedicated signaling.

In another embodiment, in a state where the power level of the terminal is at a second power level, if it is detected that the channel quality is greater than or equal to a second threshold value, the terminal triggers adjustment of the power level of the terminal to A first power level, and the second power level is greater than the first power level. Here, the second threshold value is configured by the network device, for example, the network device sends the second threshold value to the terminal through system broadcast or dedicated signaling.

For example, the UE can adjust the UE power level based on the channel environment (such as the channel quality measured by the UE). It is assumed that the current power level of the UE is the default power level, that is, 23 dBm. If it is detected that the channel quality is lower than the threshold 1, the UE triggers changing the UE power level to 26 dBm, otherwise, the UE uses the default power level, which is 23 dBm. Further, assuming that the current power level of the UE is 26 dBm, if it is detected that the channel quality is higher than the threshold 2, the UE triggers changing the UE power level to 23 dBm. Here, threshold 1 and threshold 2 depend on the network side configuration, such as system broadcast or dedicated signaling.

2) The terminal adjusts the power level of the terminal based on a second message sent by the network device, where the second message is used to indicate the power level that the terminal needs to adjust.

Specifically, the second message is triggered by the network device and sent to the terminal based on an uplink measurement result or an uplink decoding block error rate (BLER).

In one embodiment, the second message is RRC signaling, or MAC, CE, or PDCCH order.
