Abstract

Se describen tecnicas para la asignacion de espacio de Walsh. En un aspecto, se mantiene una lista de funciones de Walsh en la estacion base (104) y las estaciones moviles (106). Se transmite un indicador de espacio de Walsh para indicar cual de las funciones de Walsh en la lista va a utilizarse en la comunicacion. El indicador de espacio de Walsh se actualiza de acuerdo con la potencia de transmision dinamicamente variable disponible o el uso de funciones de Walsh en la estacion base. Se proporcionan los metodos por los cuales una estacion movil puede solicitar informacion de espacio de Walsh. En otro aspecto, se transmite continuamente un canal indicador de espacio de Walsh para las estaciones moviles a fin de detectar el indicador de espacio de Walsh desde ellas. Aun en otro aspecto, se utiliza el indicador de espacio de Walsh para inicializar codificadores convolucionales (260) y decodificadores (304), a fin de proporcionar un mecanismo para mitigar los errores introducidos mientras se reciben los indicadores de espacio de Walsh. Tambien se presentan otros diversos aspectos.
