Simultaneous Reporting of ACK/NACK and Channel-State Information using PUCCH Format 3 Resources

摘要

A new uplink control channel capability is introduced to enable a mobile terminal to simultaneously report multiple packet receipt status bits and channel-condition bits. In an example embodiment implemented in a mobile terminal the mobile terminal (first determines that channel-state information and hybrid-ARQ ACK/NACK bits corresponding to a plurality of downlink subframes or a plurality of downlink carriers, or both, are scheduled for transmission in an uplink subframe. The mobile terminal then determines whether the number of the hybrid-ARQ ACK/NACK bits is less than or equal to a threshold number. If so, the mobile terminal transmits both the channel-state information and the hybrid-ARQ ACK/NACK bits in physical control channel resources of the first uplink subframe, on a single carrier. In some embodiments, the number of the hybrid-ARQ ACK/NACK bits considered in the previously summarized technique represents a number of ACK/NACK bits after ACK/NACK bundling.

1. A method in a mobile terminal for simultaneous reporting of channel-state information and hybrid-ARQ ACK/NACK information in uplink subframes, the method comprising, at each of a plurality of reporting instances:
determining that first channel-state information and first hybrid-ARQ ACK/NACK bits corresponding to a plurality of downlink subframes or a plurality of downlink carriers, or both, are scheduled for transmission in a first uplink subframe; determining whether the number of the first hybrid-ARQ ACK/NACK bits is less than or equal to a threshold number; and transmitting both the first channel-state information and the first hybrid-ARQ ACK/NACK bits in physical control channel resources of the first uplink subframe, on a single carrier, in the event that the number of hybrid-ARQ ACK/NACK bits to be transmitted in the first uplink subframe is less than or equal to the threshold number; and, otherwise, dropping the first channel state information and transmitting the first hybrid-ARQ ACK/NACK bits in physical control channel resources of the first uplink subframe, on a single carrier, in the event that the number of hybrid-ARQ ACK/NACK bits to be transmitted in the first uplink subframe is not less than or equal to the threshold number.
