US 2013/0155968 A1 · METHOD FOR CHANNEL ESTIMATION AND PILOT RECEPTION FOR REMOTE RADIO HEAD (RRH) DEPLOYMENTS AND MULTI-ANTENNA DOWNLINK MIMO

Abstract

A method and apparatus for determining pilot information is disclosed. A wireless/transmit receive unit (WTRU) receives a plurality of high speed shared control channel (HS-SCCH) resources including radio resource control (RRC) configuration information for high speed downlink packet access (HSDPA), wherein the RRC configuration information includes dedicated pilot information associated with each received HS-SCCH resource. The WTRU detects a high speed downlink shared channel (HS-DSCH) radio network transmission identifier (H-RNTI) associated with the WTRU in one of the plurality of HS-SCCH resources. The WTRU determines pilot information, based on the dedicated pilot information and the one of the plurality of HS-SCCH resources, for a high speed physically downlink shared channel (HS-PDSCH) associated with the one of the plurality of HS-SCCH resources.
