Simultaneous transmission of acknowledgement, channel quality indicator and scheduling request

摘要

Systems and methodologies are described that facilitate simultaneous transmission of control information in a single sub-frame. For instance, simultaneous transmission can maintain single carrier waveforms for a control channel even when a plurality of information types is scheduled in concurrently. Channel quality indicators, scheduling requests and acknowledgement messages can be jointly coded. In addition, reference symbols in a sub-frame can be modulated to indicate values associated with a scheduling request or an acknowledgement message. Moreover, in situations where channel quality indicators, scheduling requests and or acknowledgement messages are simultaneously scheduled, one or more can be dropped. Further, a single carrier constraint can be relaxed to enable simultaneous transmission of information in the sub-frame at different frequencies.

1. A method of facilitating transmission of control information, the method comprising:
identifying a sub-frame in which a collision exists between two or more types of control information; detecting at least two of the two or more types of control information, including one of:
a scheduling request and an acknowledgement message scheduled in the sub-frame;a channel quality indicator and an acknowledgment message scheduled in the sub-frame;a channel quality indicator and a scheduling request scheduled in the sub- frame; oran acknowledgement message, a scheduling request and a channel quality indicator scheduled in the sub-frame; and selecting, based on the two or more types of control information associated with the identified sub-frame, between dropping one of the types of control information or jointly transmitting the two or more types of control information; and incorporating at least one of the two or more types of control information into the sub-frame.
