Claim Text:
1. A method, in a base station, for determining a control timing configuration, the control timing configuration providing a subframe timing setting for configuring Physical Uplink Shared Channel (PUSCH) and uplink Hybrid Automatic Retransmission Request Acknowledgment (HARQ-ACK) control timing for a cell serving a user equipment in a multiple cell communications network, the user equipment being served by a Time Division Duplex (TDD) based cell, and a Frequency Division Duplex (FDD) based cell, the method comprising: determining a control timing configuration for a secondary cell, the secondary cell being one of the TDD based cell and the FDD based cell, based on a type of a scheduling cell, the type of the scheduling cell being one of the FDD based cell and the TDD based cell; implementing the control timing configuration for PUSCH and uplink HARQ-ACK control timing for a cell serving the user equipment; and if the cell serving the user equipment is a TDD based cell, the determining further comprises determining the control timing configuration for the PUSCH to be equivalent to a TDD configuration of the TDD based cell.
