Abstract
The invention relates to a method, in a wireless communication System, of determining the position, of acknowledgment/non-acknowledgment information for a hybrid automatic repeat request, in a physical uplink control channel, wherein the user equipment sends in an uplink sub-frame the acknowledgment/non-acknowledgment information for one or more downlink sub-frames. In an aspect of the invention, the base station sends to the user equipment a first starting position related to each ePDCCH set, a first offset related to a mapping relationship between the uplink sub-frame and information about the number of enhanced control channel éléments per ePDCCH set. The user equipment détermines the position, of the acknowledgment/non-acknowledgment information for the hybrid automatic repeat request, in the physical uplink control channel upon réception of the foregoing information. With the inventive solution, a waste of physical uplink control channel resources can be lowered and full use of the resources can be made to thereby improve the efficiency of the System.
