"3GPP R17 协议下的通信技术：发射器特性要求及UL MIMO操作"

3GPP TS 38.101-1 V18.0.0 (2022-12)Release 186Transmitter characteristics document outlines the specifications for the transmitter characteristics of User Equipment (UE) in the context of 3rd Generation Partnership Project (3GPP) specifications. The document specifies the requirements for UL MIMO operation and outlines the general characteristics of the transmitter unless stated otherwise. The transmitter characteristics are specified at the antenna connector of the UE, whether it has a single or multiple transmit antennas. For UE with integral antenna only, a reference antenna with a gain of 0 dBi is assumed. The transmitter requirements for UL MIMO operation apply when the UE transmits on 2 ports on the same Code Division Multiplexing (CDM) group. However, the UE may use higher Maximum Power Reduction (MPR) values outside of this limitation. The document provides detailed technical specifications and requirements for the transmitter characteristics, ensuring compliance with 3GPP standards and facilitating interoperability between different UEs and network infrastructures. It serves as a crucial reference for manufacturers and operators in the development and deployment of 5G networks and services. Overall, the 3GPP TS 38.101-1 V18.0.0 (2022-12)Release 186Transmitter characteristics document plays a vital role in shaping the communication technology landscape by providing standardized specifications for UE transmitters, ultimately contributing to the advancement and efficiency of 5G networks and connectivity.
