Abstract (en)
[origin: WO9944314A1] According to the invention, the burst structure of the common air interface is adapted to the requirements in the home telephone telecommunications system for the uncoordinated operation in the paired (FDD-mode) or unpaired (TDD-mode) frequency band such that statements concerning the quality of the respective burst and, for example, criteria for the handover of a telecommunication connection, so called handover criteria are possible. To this end, the burst structure contains a first data field which is provided in the given sequence and which is provided for varying burst collision recognition (DF1SCD). Said burst structure also contains a first useful data block (NDB1), a training information sequence, the so called midamble, provided for channel estimation (TIS) and/or a synchronization field (SYF), a second useful data block (NDB2), a data field which is configured, for example, as a CRC field and which is provided for fault recognition (DFCRC), a second data field provided for varying burst collision recognition (DF2SCD) and a protection time zone (SZZ).
