Abstract

A telecommunications system (700, 800, 1000) is configured to perform a method for mapping synchronization signals. The method includes transmitting data, reference signals, synchronization signals, and control elements to at least one of a plurality of subscriber stations. The method also includes configuring e-PDCCH DMRS parameters (400, 720, 725, 825, 830, 910, 920, 1020) for each of a plurality of enhanced physical downlink control channel (e-PDCCH) sets. , 1030).

Description

technical field [0001] The present application relates generally to wireless communications and, more particularly, to systems and methods for pilot signal scrambling for enhanced physical control channels. Background technique [0002] In 3GPP Long Term Evolution (LTE) (3GPP LTE Rel-10), no matter from which transmission point (TP) the user equipment (UE) receives the downlink (DL) data signal, the UE should expect the Obtained physical cell ID The UE-specific demodulation reference signal (UE-RS) is scrambled. According to this UE behavior, the UE cannot distinguish the desired signal from the interfering signal. Contents of the invention [0003] A base station configured to communicate with a plurality of base stations via a backhaul link and configured to communicate with a plurality of subscriber stations is provided. The base station includes a transmission path configured to transmit data, reference signals, synchronization signals, and control elements to at l...
