    Abstract: Methods and apparatus are described for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) bits in a physical uplink shared channel (PUSCH) by a user equipment (UE) in a communication system. A method includes receiving a configuration of a plurality of cells, the plurality of cells being associated with one or more transport blocks; arranging HARQ-ACK bits for the plurality of cells, based on an order of cell indexes and an order of transport block indexes; encoding the arranged HARQ-ACK bits; and transmitting, to a node B, the encoded arranged HARQ-ACK bits in the PUSCH. 2 HARQ-ACK bits for a cell configured with 2 transport blocks are included in the arranged HARQ-ACK bits. The arranged HARQ-ACK bits are encoded by a (32, O) block code in case that a number of the arranged HARQ-ACK bits is 3, O being the number of the arranged HARQ-ACK bits.

    Abstract: Methods and apparatuses for transmitting and receiving at least one Downlink Control Information (DCI) in a communication system supporting Carrier Aggregation (CA) are provided. The method for receiving includes receiving information representative of presence of carrier indicator by higher layer signaling from a Node B; receiving information representative of at least one cell indicator by higher layer signaling from the Node B; defining an UE specific search space based on aggregation level, an UE ID, and at least one carrier indicator value, where the UE specific search space includes a set of Physical Downlink Control CHannel (PDCCH) candidates based on the aggregation level; decoding at least one PDCCH including at least one DCI respectively by the UE ID; and acquiring the at least one DCI, wherein the at least one carrier indicator value is based on the at least one cell indicator.

    Abstract: A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.
