Abstract

Se divulgan métodos y un aparato para transmitir informacion de control de enlace ascendente (UCI) en espectros de portadoras agregadas. La UCI puede incluir, pero sin limitarse a ello, un indicador de matriz de precodificacion (PMI), indicacion de rango (RI), indicador de calidad de canal (CQI), confirmacion/confirmacion negativa (ACK/NACK) y pedido de programacion (SR). Para agregacion de portadoras simétrica, pueden parearse portadoras de enlace ascendente (UL) y de enlace descendente (DL) y puede utilizarse un canal físico de control de enlace ascendente (PUCCH) en cada portadora componente de UL para enviar la UCI para la portadora componente de DL correspondiente. Para agregacion de portadoras asimétrica, se proveen métodos para transmision de UCI y asignacion de recursos segun la configuracion o la asignacion de portadora componente. Se proveen métodos para configuraciones de portadora componente multiples y unicas que pueden proveer, además, compatibilidad con versiones anteriores.
