Abstract
A method and apparatus to provide a common signaling channel (CSC) for concurrently signaling a multiplicity of different mobile stations (MSs) to facilitate data communications with a base station (BS). Superframes of the CSC have a length related to the period of corresponding data channel frames, so that disposing signaling information units (SIUs) in a superframe may imply relevance to particular data frames. Each CSC superframe is multiplexed by time (TDM) into subframes, which are further multiplexed by code (CDM). Symbols representing the same SIU may be disposed in plural subframes to provide time diversity. The number of subframes per superframe may be selected to reduce impairment of CDM code orthogonality, and/or to permit using an integer power of two number of symbols within each subframe. A CSC may, for example, provide ACK information for data from numerous MSs, supporting H-ARQ for reverse link transmissions.
