Code division multiplexing commands on a code division multiplexed channel

摘要

The invention discloses the technology of the efficient signaling that is used for a plurality of travelling carriages.In one embodiment, one of them that utilize a plurality of mask code sequences encoded to each of a plurality of symbols streams, this the symbols streams of mask be combined to form code division multiplexing (CDM) signal, and utilize this cdm signal of another mask code sequence to be carried out mask further, be used for carrying out code division multiplexing with a plurality of additional signals, to send to distant station with one.In another embodiment, formed a plurality of cdm signals according to symbols streams through mask, and described a plurality of cdm signal before further carrying out mask by Time Division Multiplexing.In other embodiments, separating mask and demultiplexing is performed and recovers one or more symbols streams.Other different aspect has also been proposed.The advantage that these aspects have has: the effective utilization to reverse chain-circuit capacity is provided, adaptation is such as the demand of the such variation of low time delay, high-throughput or different service quality, and reduced to provide the forward direction and the reverse link expense of these advantages, so just avoided disturbing too much and the capacity increase.
