Abstract
A method of packet concatenation in TDMA transmission is provided. The method includes the step of transmitting from a terminal in a first time slot (202), including overhead information (108-112) and symbols representing terminal data (114). The method also includes the step of transmitting from a terminal (possibly the same terminal) in a subsequent time slot (204-208), including a subset of the overhead information (108-112) and symbols representing terminal data (114). The subsequent time slot may be a consecutive time slot. The overhead information may include, for example, guard time (110), ramp time beam settling time (108) and a preamble (112).
Claims20
A method of packet concatenation in TDMA transmission, said method comprising:
- (a) transmitting from a first time slot including overhead information and symbols representing first terminal data, said overhead information including synchronization information;
