METHOD AND DEVICE FOR CHANNEL MULTIPLEXING OR DEMULTIPLEXING

摘要

The present invention relates a method and device for multiplexing a first transmission channel having a first transmission time interval for data unit transmission and at least one second transmission channel having a second transmission time interval for data unit transmission. A stream of placeholder bits is supplied to a channel multiplexing function of the at least one second transmission channel. The placeholder bits are then replaced at a later stage by an actual data stream of thefirst transmission channel. Furthermore, the present invention relates to a method and device for demultiplexing the first transmission channel and the at least one second transmission channel, wherein at least one of predetermined positions and numbers of data units of the first transmission channel are derived from a receiving signal containing a data stream multiplexed according to a channel multiplexing scheme of the second transmission channel. The data units located at the determined positions are copied and separately processed according to a processing scheme of the first transmission channel. Thereby, a simple way of multiplexing and demultiplexing an enhanced transmission channel with a shorter transmission time interval can be provided without increasing the peak to average power ratio and complexity.
