Abstract
Se proporcionan un método y un aparato para la retransmision cooperativa en comunicaciones inalámbricas. Se divulga un esquema de retransmision eficaz y simplificado que pasa por diferentes modos en cada paquete utilizando informacion de programacion o cambiando informacion incluida en el paquete, sin requerir la reconfiguracion del enlace. El esquema de retransmision cooperativa también se beneficia del uso de protocolos de retransmision cooperativa que enfatizan la programacion centralizada. Un protocolo enfatiza la cooperacion de capa física a través de transmisiones sincronizadas y codificacion de espacio-tiempo distribuida y el otro protocolo enfatiza la cooperacion de capa de control de acceso al medio (MAC) utilizando diferentes flujos o mensajes MAC.
