Abstract

Abstract A time division multiplexed communications method and system in which time is divided into a number of frames and each frame is divided into N data bursts. The method and system further has a first multiplexer by which a half rate channel is formed as a series of bursts that occur periodically every N bursts once per frame, a second multiplexer in which a full rate channel is formed as two half rate channels on consecutive timeslots, and a transmitter transmitting the full rate channel from a first wireless station to a second wireless station. The full rate channel provided by two half rate channels on consecutive timeslots yields a significantly larger resource pool available for assignment of communication traffic. For full rate channels, the interleaving 0246/1357 method that is used by the system is just as good as the known 0123/4567 method when ideal frequency hopping is used, and the 0246/1357 method performs better when non-ideal frequency hopping or no frequency hopping is used.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 105 words
A system for communicating using wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, said system comprising: means for defining a half rate channel as a series of bursts that occur periodically every N data bursts once per frame; means for defining a flail rate channel as two consecutive half rate channels; and means for transmitting said full rate channel from a first station to a second station, wherein 0246/1357 interleaving us used with frequency hopping transmitting of said full rate channel because of the improved link performance provided thereby.
Claim 2
Independent Claim 105 words
A system for communicating using wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, said system comprising: means for defining a half rate channel as a series of bursts that occur periodically every N data bursts once per frame; means for defining a flail rate channel as two consecutive half rate channels; and means for transmitting said full rate channel from a first station to a second station, wherein 0246/1357 interleaving us used with frequency hopping transmitting of said full rate channel because of the improved link performance provided thereby.
Claim 3
Dependent Claim 36 words
The system of claim 1 , wherein 0246/1357 interleaving is used because of a lower delay to the start of a talkspurt of said half rate channels and hence said full rate channel than 0123/4567 interleaving.
Claim 4
Independent Claim 114 words
A system for communicating using wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, said system comprising: means for defining a half rate channel as a series of bursts that occur periodically every N data bursts once per frame; means for defining a full rate channel as two consecutive half rate channels; and means for transmitting said full rate channel from a first station to a second station, wherein 0246/1357 interleaving is used because of larger resource pools for statistical multiplexing under half duplex constraints imposed by mobile stations provided for said full rate channel relative to 0123/4567 interleaving.
Claim 5
Independent Claim 114 words
A system for communicating using wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, said system comprising: means for defining a half rate channel as a series of bursts that occur periodically every N data bursts once per frame; means for defining a full rate channel as two consecutive half rate channels; and means for transmitting said full rate channel from a first station to a second station, wherein 0246/1357 interleaving is used because of larger resource pools for statistical multiplexing under half duplex constraints imposed by mobile stations provided for said full rate channel relative to 0123/4567 interleaving.
