Description

Maximum power reduction This specification relates to mobile communication. Thanks to the success of LTE (long term evolution)/LTE-Advanced (LTE-A) for 4th generation mobile communication, interest in the next generation, namely 5th generation (so-called 5G) mobile communication, is also rising, and research is being conducted one after another. New radio access technology (New RAT or NR) has been researched for the above-mentioned 5th generation (so-called 5G) mobile communication. In 5G, the terminal can perform communication based on the LTE band 41 + NR band 41 EN-DC (Evolved Universal Terrestrial Radio Access (E-UTRA) - New Radio Dual Connectivity) mode. Here, the LTE band 41 + NR band 41 EN-DC mode may refer to a communication mode using LTE band 41 and NR band 41 (e.g., n41). The terminal can determine the transmission power by applying maximum output power requirements (or requirements). For example, the maximum output power requirements may be Maximum Power Reduction (MPR) values and/or Additional-MPR (A-MPR) values. Recently, there has been discussion regarding the implementation of a 29dBm high-power terminal supporting LTE band 41 + NR band 41 EN-DC operation. However, conventionally, only maximum output power requirements (e.g., MPR and/or A-MPR) for a 26dBm high-power terminal supporting LTE band 41 + NR band 41 EN-DC operation have been defined. Therefore, there is a problem in that there are no maximum output power requirements (e.g., MPR and/or A-MPR) applicable to a 29dBm high-power terminal supporting LTE band 41 + NR band 41 EN-DC operation. Figure 1 is a wireless communication system. Figure 2 shows the structure of a radio frame according to FDD in 3GPP LTE.
