Abstract: A method for determining resources to be decoded by the UE to retrieve physical downlink control channels. A method is in a UE or an eNB and comprises the following steps of: i. determining a start position of a unit of resources in one physical resource block pair; ii. determining a gap between two of the units; and iii. 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. In this way, the eNB and the UE can locate all the resources for the EPDCCH, namely the search space is determined. This aspect allows a balance between the number of blind decoding and eNB scheduling flexibility in the EPDCCH search space.

Abstract: The present invention provides a system and method for protecting data stored in the control registers of an integrated circuit, such as a television chip. The system and method use one or more selectively activated read protection modules to prevent the control registers from being read unless a predetermined key or password is entered. The password or key may be stored in password registers within the chip. A key access generator will enable read access of the control registers if correct values are written to the appropriate password registers. The key access generator may enable read access for a predetermined period of time or until it receives another input.
