FIELD: radio engineering, communication.
SUBSTANCE: simultaneous transmission can maintain single carrier signals for a control channel even when a plurality of information types is scheduled simultaneously. Channel quality indicators, scheduling requests and acknowledgement messages can be jointly coded. 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.
EFFECT: facilitating simultaneous transmission of control information in one sub-frame.
