Title:
MULTI-CHANNEL TRANSMISSION AND RECEPTION WITH BLOCK CODING IN A COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2004049617
Kind Code:
A3
Abstract:
Techniques for transmitting and receiving multiple channels with block coding in a communication system are disclosed. In one aspect, a secondary broadcast channel (320) is transmitted concurrently with parity information, encoded from a primary broadcast channel (310). In another aspect, a mobile station(106)repurposes its receiving circuitry to receive one or more portions of the secondary broadcast channel after a sufficient portion of the primary broadcast channel is received without identified error. In another aspect, secondary broadcast channels associated with a plurality of primary broadcast channels (610) are multiplexed onto a single secondary channel (620). Various other aspects are also presented. These aspects have the benefit of minimizing mobile station resources required to receive multiple broadcast channels, as well as reducing the complexity and channel resources required to transmit multiple broadcast channels.
