Abstract
Some of the example embodiments are directed towards a base station for determining a control timing configuration in order to provide a subframe timing setting for configuring downlink HARQ-ACK control timing for a cell serving a user equipment in a multiple cell communications network. The user equipment is served a TDD based cell and a FDD based cell. Some example embodiments are directed towards the user equipment the control timing configuration as discussed above.

A method, in a base station, for determining a control timing configuration, the control timing configuration providing a subframe timing setting for configuring downlink 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 control timing configuration of a primary cell, the primary cell being one of the FDD based cell and the TDD based cell;
- and
- implementing the control timing configuration for downlink HARQ-ACK control timing for a cell serving the user equipment.
