CA 2507235

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.

L'invention porte sur des techniques d'émission et de réception sur plusieurs canaux par codage de bloc dans un système de communication. Selon une variante, une transmission sur un canal de diffusion secondaire (320) est effectuée simultanément avec des informations de parité, codées à partir d'un canal de diffusion primaire (310). Selon une autre variante, une station mobile (106) recycle le circuit récepteur pour la réception d'une ou plusieurs parties sur le canal de diffusion secondaire après avoir reçu une partie suffisante sur le canal de diffusion primaire sans identification d'erreur. Selon encore une autre variante, les canaux de diffusion secondaires associés à une pluralité de canaux de diffusion primaires (610) sont multiplexés sur un canal secondaire unique (620). D'autres variantes sont également présentées. Ces variantes ont l'avantage de minimiser les ressources de la station mobile nécessaires pour une réception sur plusieurs canaux de diffusion, et de réduire les ressources de complexité et des canaux nécessaires pour une transmission sur plusieurs canaux de diffusion.
