Abstract
Methods and apparatus are described for a User Equipment (UE) configured with multiple cells in the downlink of a time division duplex communication system to transmit HARQ-ACK information in a Physical Uplink Shared CHannel (PUSCH), to map HARQ-ACK bits transmitted in a PUSCH to information regarding correct or incorrect detections of data transport blocks in different cells and different transmission time intervals, and to provide a same understanding with an intended reception point of the information represented by HARQ-ACK bits the UE transmits in a PUSCH.

A method for transmitting acknowledgement information in response to data Transport Blocks (TBs) received in one or more downlink data channels by an User Equipment (UE) in a Time Division Duplex (TDD) communication system, the method comprising the steps of:
- generating acknowledgement information respectively representing a reception result for each data TB by a corresponding acknowledgement bit, if a first condition applies;
- generating acknowledgement information jointly representing state of reception results for a plurality of data TBs, if a second condition applies;
- and
- transmitting the generated acknowledgement information in an uplink data channel.
A User Equipment (UE) for transmitting acknowledgement information in response to data Transport Blocks (TBs) received in one or more downlink data channels in a Time Division Duplex (TDD) communication system, the apparatus comprising:
- a controller for generating acknowledgement information respectively representing a reception result for each data TB by a corresponding acknowledgement bit, if a first condition applies, and generating acknowledgement information jointly representing state of reception results for a plurality of data TBs, if a second condition applies;
- and
- a transmitter for transmitting the generated acknowledgement information in an uplink data channel.
