Embodiment Construction

[0049] The SAR index is related to whether the terminal can pass the certification test and obtain the sales qualification. Different countries have different standards for SAR certification. Some countries have higher requirements for SAR, while others have relatively lower requirements for SAR. In order to adapt to the SAR requirements of different countries, the present invention proposes a scheme to dynamically identify operators in different countries. In countries with higher SAR requirements, a relatively low transmission power is used; in countries with lower SAR requirements, then Use a relatively high transmit power. In this way, the contradiction between transmission power and SAR can be coordinated while the size remains competitive, and at least some countries can obtain relatively good transmission power and TRP indicators.

[0050] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present inventio...

Abstract

The embodiment of the invention discloses a transmitting power adjusting method and a terminal. The method comprises the following steps that: the terminal acquires the public land mobile network (PLMN) identification information of a network side; the terminal looks up a transmitting power value range corresponding to the PLMN identification information of the network side according to a one-to-one relationship between the PLMN identification information and transmitting power value ranges, wherein the transmitting power value range corresponding to the PLMN identification information of the network side meets the specific absorption rate (SAR) requirement of the network side; and the transmitting power of the terminal is set to satisfy the transmitting power value range corresponding to the PLMN identification information of the network side. Through the embodiment of the invention, the contradiction between the transmitting power and the SAR is coordinated under the situation of keeping the competitiveness.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a transmission power adjustment method and a terminal. Background technique [0002] For communication terminals such as data cards and E5, generally speaking, the higher the transmission power of the terminal within the protocol range, the better. Higher transmission power can obtain better coverage. The total radiation power (Total Radiation Power, TRP ) indicators will be higher, which can meet the requirements of many operators for TRP. However, when the terminal size and hardware solution are determined, too high transmit power may cause the radio frequency energy absorption ratio (Specific Absorption Rate, SAR) to exceed the certification standard. [0003] Since the SAR index is related to whether the terminal can pass the certification test, when encountering the above-mentioned contradiction between TRP and SAR, the usual practice is to keep the transmit ...
