Problems solved by technology

Making this partition known to the UE via Radio Resource Control (RRC) can result in significant overhead
Furthermore, the specification of these values ​​as done in Rel-8 is not straightforward due to the number of combinations of potentially different sized sets that can be configured for a UE
[0031] Furthermore, frequency reuse gain is sometimes compromised when the blind decoding candidates tested by the UE occur consecutively

Abstract

A method of operating a network node (1100) is provided. Various embodiments may provide a method of processing enhanced physical downlink control channel ePDCCH information by a network node (1100) of a wireless telecommunication system. The method may include distinguishing (300) sets of physical resource block PRB pairs in an ePDCCH control region when defining blind decoding candidates (X). Furthermore, the method may include scheduling (301) resources for the user equipment UE in response to distinguishing (300) the set of PRB pairs. The associated network node (1100) and UE (1200) are also described.

Description

[0001] claim priority [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 707285, entitled "ePDCCH Blind Decode Partitioning and Search Candidate Hashing," filed September 28, 2012, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure is directed to communications, and more specifically to methods of processing enhanced physical downlink control channel (ePDCCH) information and related network nodes and user equipments. Background technique [0004] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) technology is a mobile broadband wireless communication technology in which transmissions from a base station (such as an evolved Node B (eNB)) to a mobile station (such as a user equipment (UE)) use Orthogonal Frequency Division Multiplexing (OFDM) to transmit. OFDM divides a signal in frequency into multiple parallel subcarriers. The basic u...
