摘要
The technology that the combination of using explicit circulation delay and implicit cyclic delays transmits data has been described.The first circulation delay value set that transmitter can be based upon known to the receiver is carried out first cyclic delay diversity processing (or explicit circulation delay is handled).Transmitter can or before explicit circulation delay is handled or carry out precoding based on pre-coding matrix afterwards.Transmitter can be handled (or implicit cyclic delays processing) based on not carrying out second cyclic delay diversity for the second circulation delay value set known to the receiver.Transmitter can not only be carried out explicit circulation delay processing but also carries out implicit cyclic delays and handle data, and can only carry out implicit cyclic delays to pilot tone and handle.An entity can be selected the first circulation delay value set and notify other entities.Transmitter independently (for example, pseudorandom ground) is selected the second circulation delay value set and is not notified receiver.
