NODE AND METHOD FOR DOWNLINK SCHEDULING AND HYBRID AUTOMATIC REPEAT REQUEST TIMING

摘要

Embodiments are directed towards a base station, and corresponding method therein, for determining a control timing configuration. The control timing configuration provides a subframe timing for configuring PUSCH and uplink HARQ-ACK control timing for a cell serving a user equipment in a multiple cell communications network. The user equipment is served by a TDD based cell and a FDD based cell. are also directed towards a user equipment, and corresponding method therein, determining the control timing configuration discussed above.

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; and implementing the control timing configuration for PUSCH and uplink HARQ-ACK control timing for a cell serving the user equipment.
