In this embodiment, the terminal may determine the second maximum of the target channel/signal according to the calculated current SAR value of the terminal, and the preset maximum SAR value, and the first maximum transmit power of the pre-configured target channel/signal. The power is transmitted for the terminal to determine the actual transmit power of the target channel/signal to prevent the SAR value of the terminal from exceeding the standard. The second maximum transmit power may be less than or equal to a first maximum transmit power P _CMAX,f,c (i) of the pre-configured target channel/signal.

Optionally, in a possible implementation manner of the embodiment, the target channel/signal may be a physical uplink shared channel (PUSCH), or may also be a physical uplink control channel (Physical Uplink Control Channel) , PUCCH), or may be a Sounding Reference Signal (SRS), which is not specifically limited in this embodiment.

In a specific implementation process, the adjustment parameter δ may be the cumulative adjustment parameter ∑δ(t), or may be a single adjustment parameter δ(t), which is not specifically limited in this embodiment.

In another specific implementation process, before the terminal determines the second maximum transmit power by using the pre-configured adjustment parameter δ according to the first maximum transmit power, the terminal may further send the first to the network device. The indication information is used to indicate the adjustment parameter.

In another specific implementation process, before the terminal determines the second maximum transmit power by using the pre-configured adjustment parameter δ according to the first maximum transmit power, the adjustment parameter may be configured by the network device. Specifically, the terminal may further receive second indication information sent by the network device, to indicate the adjustment parameter.

Specifically, the terminal may specifically receive an adjustment parameter sent by the network device by using Downlink Control Information (DCI), high layer signaling, or system broadcast message.

For example, the high-level signaling may be a radio resource control (RRC) message, and the adjustment parameter may be carried by an information element (IE) in an RRC message, where the RRC message may be existing. The RRC message in the technology, for example, the RRC CONNECTION RECONFIGURATION message, is not limited in this embodiment, and the IE of the existing RRC message is extended to carry the adjustment parameter, or the RRC. The message may also be different from the RRC messages already available in the prior art.

Or, for example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the adjustment parameter may be carried by adding a new MAC CE message.

Alternatively, for example, the existing primary information block (MIB) or the (System Information Block (SIB) in the system broadcast message may be used to carry the adjustment parameter, or a new SIB carrying device may be added. The adjustment parameters are described.

It can be understood that the adjustment parameters can also be agreed by a protocol.

In another specific implementation, the second maximum transmit power is a minimum of both P _{CMAX, f, c} (i) and P _{CMAX, f, c} (i) + δ. In this way, it is possible to effectively ensure that the second maximum transmission power is less than or equal to the first maximum transmission power P _CMAX,f,c (i) of the pre-configured target channel/signal.

In this way, the terminal and the network device can determine the first time unit N, that is, N-K+K, according to the values of the second time units N-K and K. After determining the first time unit, that is, the first time unit N, the terminal and the network device may further determine a plurality of first time units that are consecutive after the first time unit N. In this way, the terminal may use the second maximum transmit power as the maximum transmit power of the target channel/signal in the at least one first time unit.

In the implementation process, the first trigger information may further include, but is not limited to, at least one of the following information:

a portion of the at least one first time unit (eg, the first time unit N) or all of the first time unit;

Or, for example, in this implementation, if the first trigger information further includes an adjustment parameter δ. Thus, the terminal may according to the first maximum transmission power _{P CMAX, f, c (i} ), using the adjustment parameter [delta], the second maximum transmission power is determined i.e. _{P CMAX, f, c (i} ) + δ.

The adjustment parameter δ may be the cumulative adjustment parameter ∑δ(t), or may be a single adjustment parameter δ(t), which is not particularly limited in this embodiment.

Or the RRC message may also be different from the existing RRC message in the prior art.

Or, for example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and the value of the S may be carried by adding a new MAC CE message.

Or, for example, the value of the S may be carried by using an existing Master Information Block (MIB) or a System Information Block (SIB) in the system broadcast message, or a new SIB may be added. Carrying the value of the S.

It can be understood that the value of the S can also be agreed by the protocol.

It can be understood that the value of the S may not be pre-configured by the network device or agreed by the protocol, but directly indicated by the specific content of the second trigger information.

In this way, the terminal and the network device can determine the first time unit N, that is, N-S+S, according to the values of the second time units N-S and S. After determining the first time unit, that is, the first time unit N, the terminal and the network device may further determine a plurality of first time units that are consecutive after the first time unit N.

The downlink control signaling is used to schedule the target channel/signal transmission; or

The downlink control signaling is transmitted through a Common Search Space (CSS) of a Physical Uplink Control Channel (PUCCH); or

Or, for example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and the second trigger information may be further carried by adding a new MAC CE message.

Alternatively, for example, the second trigger information may be carried by using an existing primary information block (MIB) or a system information block (SIB) in the system broadcast message, or a new SIB may be added. Carrying the second trigger information.

In this implementation, the second maximum transmit power is a minimum of both P _{CMAX, f, c} (i) and P _{CMAX, f, c} (i) + δ. In this way, it is possible to effectively ensure that the second maximum transmission power is less than or equal to the first maximum transmission power P _CMAX,f,c (i) of the pre-configured target channel/signal.

In this embodiment, the first time unit, the second time unit, and the third time unit may be time slots, or may be a subframe, or may also be a symbol, which is not used in this embodiment. Special restrictions are made.

In this embodiment, the second maximum transmit power of the target channel/signal is determined by the terminal according to the first maximum transmit power of the pre-configured target channel/signal, so that the terminal can send the second maximum transmit power. As the maximum transmit power of the target channel/signal in the at least one first time unit, since the terminal can actively adjust the maximum transmit power of the target channel/signal within a certain time range, the high power terminal can be effectively avoided.
