Method for determining resources of physical downlink control channels

An apparatus, in a UE or an eNB, for determining resources to be decoded by the UE to retrieve physical downlink control channels, comprising:

• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
• determining a start position of a unit of resources in one physical resource block pair according to UE specific information;
• determining a gap between two of the units;
• determining a set of units, in a given plurality of physical resource block pairs, according to said start position and said gap, as the resources to be decoded;
• wherein the gap between two of the units is not an integer-multiple of the size of one of the physical resource block pairs.
