摘要： Embodiments of the present invention provide a data sending method. The data sending method includes: determining, according to location generation information of a PDCCH on a non-legacy resource, a resource location, on a subframe, of the PDCCH on the non-legacy resource; and sending the subframe to a UE, where the PDCCH on the non-legacy resource is contained on the resource location of the subframe, so that the UE determines the resource location, on the subframe, of the PDCCH on the non-legacy resource according to the location generation information. In the embodiments of the present invention, both the base station and the UE may determine a resource location of the PDCCH on the non-legacy resource separately by using the location generation information, thereby avoiding a circumstance that the UE equipped with only the capability of receiving a PDCCH on a non-legacy resource cannot access a network.

摘要： The present invention discloses a method and a device for transmitting information on a physical uplink control channel (PUCCH). The method includes the following steps: a user equipment (UE) selects information from channel state information (CSI) to transmit (S1); the information selected from the CSI is transmitted on the PUCCH with one or both of hybrid automatic retransmission acknowledgment information and a scheduling request (S2), which enables a base station to obtain not only the information in the CSI but also one or both of the hybrid automatic retransmission acknowledgement information and the scheduling request from the PUCCH. The present invention avoids the problem of system downlink throughput degradation caused by dropping all CSI by the UE in the prior art, and avoids the problem that system downlink throughput is influenced by unnecessary data retransmission on a downlink carrier caused by ACK/NACK bundling among carriers.
