Abstract
The present disclosure provides a UE. The UE includes at least one transceiver; at least one processor; and at least one memory that stores instructions and is operatively electrically connectable with the at least one processor. Operations performed based on the command being executed by the at least one processor may include: determining transmission power; and a step of transmitting an uplink signal based on the transmission power.
Claims20
A User Equipment (UE) comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory that stores instructions and is operably electrically connectable with the at least one processor,
- wherein operations performed based on the instructions being executed by the at least one processor include:
- setting a maximum output power;
- and
- transmitting an uplink signal based on the maximum output power, wherein the maximum output power is based on a Maximum Power Reduction (MPR) for power class 1.5 with four transmit antenna connectors of the UE,
- and
- wherein the MPR for the power class 1.5 with the four transmit antenna connectors of the UE is based i) antenna isolation being 10 dB, or 20 dB or above, ii) a Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (OFDM) (DFT-s-OFDM) or a Cyclic Prefix OFDM (CP-OFDM), iii) an edge Resource Block (RB) allocation, an outer RB allocation, or an inner RB allocation, and iv) a Pi/2 Binary Phase-Shift Keying (BPSK), a Quadrature Phase Shift Keying (QPSK), a 16 Quadrature Amplitude Modulation (QAM), a 64 QAM, or a 256 QAM.
