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 (1310) 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 (1320) 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 (1330) 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.
