HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK TRANSMISSION IN A MULTI COMPONENT-CARRIER COMMUNICATION SYSTEM USING SCHEDULING REQUEST RESOURCES

摘要

Methods, systems, devices, and computer program products are described which facilitate the transmission and reception of acknowledgment/negative acknowledgment (ACK/NACK) feedback associated with downlink data transmissions in a multi-carrier wireless communication system. Scheduling request resources may be utilized to enable the transmission of ACK/NACK feedback for the multiple component carriers when a positive scheduling request is present and the techniques described may be utilized to improve the efficiency of control channel signaling in different system configurations.
