Sub-channels for random access channel in time division duplex of systems.

摘要

A method for defining sub-channels to channels of physical random access communications system division duplex while using code division multiple access, which sub-channels are used by the system to separate different types of access services the method comprising: providing a series of radio frames having a sequence of timeslots; for a particular timeslot number of the sequence, uniquely defining each sub of-channel of the particular timeslot number by one radio frame of the series.
