摘要： A method of communication in a time division duplex (TDD) satellite communication system comprising at least one satellite (2) and a plurality of terrestrial terminals (4) comprises allocating time division multiple access (TDMA) time slots (l, 3) for transmission between the satellite and any one of the plurality of terminals, such that for any given terminal, transmit time slots for transmission to the satellite and receive time slots (5, 6) for reception from the satellite are separated in time. An assigned time delay between transmit and receive time slots at the any one terminal is small compared with a round trip propagation delay and if the transmit time slot for one terminal causes a transmission from that one terminal to be received at another terminal overlapped in time with a receive time slot allocated for the other terminal, then those two terminals are spaced apart in distance, sufficiently, such that interference between the two terminals is minimised.
摘要翻译：包括至少一个卫星（2）和多个地面终端（4）的时分双工（TDD）卫星通信系统中的通信方法包括分配用于传输的时分多址（TDMA）时隙（1,3）在卫星和多个终端中的任一个之间，使得对于任何给定的终端，用于传输到卫星的发射时隙和用于从卫星接收的接收时隙（5,6）在时间上分离。在任何一个终端处的发送和接收时隙之间的分配的时间延迟与往返传播延迟相比较小，并且如果一个终端的发射时隙导致来自该一个终端的传输在另一个终端处被接收，分配给另一终端的接收时隙，那么这两个终端足够地间隔开距离，使得两个终端之间的干扰最小化。
