Sub-channels for the random access channel in time division duplex |
摘要 |
Sub-channels are defined for a physical random access channel of a wireless time division duplex communication system using code division multiple access. The sub-channels carry information between system users and a system network. A series of radio frames have a sequence of timeslots. For a particular timeslot number of the sequence, each sub-channel of the particular timeslot number is uniquely defined by one radio frame of the series.
