Abstract: The present disclosure provides a method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information. In the method provided by the present disclosure, an evolved Node B (eNB) transmits Downlink Assignment (DL-GRANT) within a time-frequency bundling window, which corresponds to an uplink subframe feeding back HARQ-ACK. A UE receives DL-GRANT scheduling downlink HARQ transmission in the time-frequency bundling window corresponding to respective uplink subframe for feeding back HARQ-ACK in turn, obtains a DL DAI in the DL-GRANT, and determines a mapping value of each DL DAI; then, maps HARQ-ACK bits of the time-frequency bundling window corresponding to respective uplink subframe for feeding back the HARQ-ACK to corresponding bits of a feedback bit sequence according to the mapping value of the DL DAI; and transmits the HARQ-ACK on an available uplink carrier. The present disclosure also provides a method for feeding back HARQ-ACK information. The UE transmits HARQ-ACK on an indicated carrier according to indication information of a base station. According to the method and apparatus provided by the present disclosure, efficiency for feeding back the HARQ-ACK can be increased and downlink peak rate of the UE can be ensured.

Abstract: A first device senses scheduling assignment (SA) and received power of a second device, and a total received energy of each subband. The first device determines a reference value of received power of the second device and a reference value of total received energy, based on a sensing result of the second device. The first device selects a resource, based on the reference value of received power and reference value of total received energy, the first device transmits data. By adopting the method of the present disclosure, decoding performance of SA is improved, and accuracy for measuring received power of the SA is also enhanced. Subsequently, on the basis of SA and received power, performances for selecting/re-selecting channel resources are improved.
