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 5 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 .o 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 BIT N CSI NO SCHEDULED? 1310 AIU N UBK ITS NO <=THRESHOLD? USE DEFAULT TECHNIQUE TO YES TRANSMIT ONLY ACK/NACK TRANSMIT BOTH ACK/NACK BITS AND CSI REPORT, USING FORMAT THAT SUPPORTS BOTH I RECEIVE UPLINK SUBFRAME WITH CONTROL CHANNEL INFORMATION IN PHYSICAL CONTROL CHANNEL RESOURCE EXPECTED NO NUMBER OF ACK/NACK YE S USE DEFAULT TECHNIQUE TO DECODE ONLY ACK/NACK FROM RESOURCE DECODE CSI REPORT AND ACK/NACK BITS FROM RESOURCE
