REFERENCE SIGNALS AND COMMON SEARCH SPACE FOR ENHANCED CONTROL CHANNELS

Title:

REFERENCE SIGNALS AND COMMON SEARCH SPACE FOR ENHANCED CONTROL CHANNELS

Document Type and Number:

WIPO Patent Application WO/2013/165216

Kind Code:

A1

Abstract:

Methods and apparatuses for a User Equipment (UE) to receive signaling of UE-common Downlink Control Information (DCI) in a set of Physical Resource Blocks (PRBs) over a Transmission Time Interval (TTI) are provided. The UE demodulates UE-common DCI using a Reference Signal (RS) that is scrambled by a UE-common scrambling sequence. The UE may assume that RS having a same precoding is transmitted in the set of PRBs over different TTIs. The UE may determine the scrambling sequence implicitly from an identity of a point transmitting the UE-common DCI or explicitly by higher layer signaling. The UE may determine the PRBs of UE-common DCI transmission by broadcast signaling or by higher layer signaling.
