本工作项TM-04099的目的是根据现有的EN 301 213标准创建一个新的章节（第5部分）。本工作项目将讨论在24.25至29.5GHz频段运行的多载波TDMA系统。新的第5部分将成为多载波TDMA系统的标准，其中每个载波可能具有不同的容量、输出电平和调制。工作项TM-04098解决了特定和限制条件，以临时解决同一信道内相同调制载波的多载波TDMA系统问题。 对EN 301 213-3的修改将纳入多载波TDMA问题，并将纳入新的第5部分。一旦第5部分被接受，将创建一个新的工作项来修改第3部分，以消除多载波TDMA系统的所有相关问题。

The purpose of this work item TM-04099, is to create a new section (Part 5) to the existing EN 301 213 standard. This work item will address Multi-Carrier TDMA systems operating in the frequency band of 24.25 to 29.5GHz. The new part 5 will be a standard for Multi-carrier TDMA systems where each carrier may have different capacity, output level, and modulation. The Work Item TM-04098 has addressed specific and restricted conditions to temporarily address the Multi carrier TDMA system concerns for identically modulated carriers within the same channel. The changes to EN 301 213-3 that will incorporate the multi carrier TDMA issues will be adopted into the new part 5. Once the part 5 has been accepted, a new work item will created to amend the part 3 to remove all related issues to Multi carrier TDMA systems.
