Abstract
Implementing asymmetrical wireless communications without significant wastage of bandwidth within the up-link block of frequency spectrum is becoming increasingly important. If the frequency spectrum is divided such that a single up-link block is paired with a plurality of corresponding down-link blocks of similar bandwidth size and respective fixed frequency offsets, the bandwidth efficiency of spectrum usage can improve when considering many data applications such as the Internet. MTs that utilize different down-link blocks can share a common up-link block so that, in ideal statistical situations, the up-link block statistically runs out of bandwidth at approximately the same time as the combination of the down-link blocks. With fixed frequency offsets between the up-link block and each of the plurality of down-link blocks, the design of the STS and the MTs can be kept reasonably simple.
