Node and method for downlink planning and hybrid automatic repeat request timing

摘要

One method, at a base station, for determining a control timing setting, the control timing setting providing a subframe timing setting for configuring the hybrid automatic retransmission request acknowledgment control timing, HARQ-ACK , downlink for a cell that serves a user equipment in a multi-cell communications network, in which the user equipment is served by a time-based duplexing cell, TDD, and a cell based on frequency division duplexing, FDD, comprising the method: determining (10) a control timing configuration for a secondary cell, the secondary cell being the TDD-based cell, based on a control timing configuration of a primary cell, the primary cell being the cell based on FDD, in which the primary cell is the cell based on TD D and the secondary cell is the FDD based cell, further comprising the determination (10) determining (18) the control timing configuration based on a first altered configuration table, in which the first altered configuration table is: * * Table ** and implement (32) the control timing configuration for the downlink HARQ-ACK control timing for a cell serving the user equipment.
