Abstract: Embodiments of the present invention provide an uplink control information transmission method, a base station, and user equipment. The method includes: receiving, by UE in a downlink subframe N, a downlink control channel sent by a base station; sending, by the UE, a hybrid automatic repeat request-acknowledgement corresponding to the downlink control channel to the base station in an uplink subframe N+4 by using a PUCCH, where when the uplink subframe N+4 belongs to a first uplink subframe set, the PUCCH is carried on a second serving cell of the UE, and when the uplink subframe N+4 belongs to a second uplink subframe set, the PUCCH is carried on the first serving cell, where a duplexing mode of the first serving cell is different from a duplexing mode of the second serving cell.

Abstract: A frequency domain resource configuration method and apparatus, the method including obtaining, by a base station, a first frequency hopping parameter set of UE in N sub-bands, where the N sub-bands have a mapping relationship with a frequency hopping pattern that is indicated by the first frequency hopping parameter set, where the sub-band is a length of consecutive frequency domain resources in a system bandwidth, and where N≧1, and further including sending, by the base station, first configuration information to the UE, where the first configuration information includes sub-band identifiers of the N sub-bands and the first frequency hopping parameter set.

Abstract: A system and method for transmitting a reference signal in a cell that uses an unlicensed frequency band. The method includes determining a candidate resource set that is used when a first reference signal is transmitted in the cell that uses the unlicensed frequency band, where the candidate resource set includes a preset resource and at least one flexible candidate resource, determining a first candidate resource that is used when the first reference signal is transmitted in the cell that uses the unlicensed frequency band, where a channel on the unlicensed frequency band corresponding to the first candidate resource is in an idle state, and the first candidate resource is the preset resource or a flexible candidate resource in the candidate resource set, and sending the first reference signal on the first candidate resource.

Abstract: Methods and nodes are provided for transmission of information, over at least one antenna port, in a subframe, which information is received by a receiver in a wireless communication system. Demodulation of the information entity by the receiver is enabled by also transmitting a Demodulation Reference Signal, DM-RS, comprising a DM-RS pattern, wherein positions in the DM-RS pattern are associated with at least one antenna port for transmission of the information entity. The method includes defining, for at least one subframe, a set of at least two distinct DM-RS patterns, assigning one DM-RS pattern, from the defined set of DM-RS patterns, to the receiver, and transmitting the information entity on the at least one antenna port associated with the assigned DM-RS pattern.
