摘要： The disclosure relates to data transmission method and apparatus for transmitting UL grant or ACK/NACK at flexible subframes in a Time Division Duplex (TDD) system. The data transmission method of a base station according to the present invention includes configuring subframes irrelevant to Hybrid Automatic Repeat reQuest (HARQ) process as flexible subframes; scheduling uplink transmission at the flexible subframes with uplink grant; receiving uplink data transmitted by a terminal at the flexible subframes as scheduled; and transmitting, when decoding the uplink data fails, HARQ acknowledgement/negative acknowledgement (ACK/NACK) or uplink grant to request retransmission of the uplink data. The data transmission method of the present invention is capable of utilizing flexible subframes for uplink transmission without influencing the uplink HARQ process associated with the downlink subframes configured as flexible subframes.

摘要： 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.
