Abstract:
A method performed by a WTRU may comprise receiving a beamformed physical control channel using a first beamformed pilot signal. The beamformed physical control channel may include an indication of a beam for a physical shared channel. The indicated beam of the physical shared channel and a beam of the beamformed physical control channel may be different. The method may further comprise receiving, based on the indicated beam, the physical shared channel using a second beamformed pilot signal. In an embodiment, the WTRU may receive an RRC message including an indication of a code of the first beamformed pilot signal.
Abstract:
Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) to determine rank, offset, or inter-stream interference control information, for example, which may be associated with uplink MIMO operations. A method to control a WTRU may include receiving a special E-RNTI that is associated with a channel. The channel may be associated with a rank indication. The channel may be an E-AGCH-like channel. The channel may have a similar encoding structure as an E-AGCH. The channel may be an E-ROCH. The channel may be received, and it may be determined that the channel is associated with the special E-RNTI. At least one of a rank or an offset may be determined, and the WTRU may be configured with the determined rank or offset. An inter-stream interference (ISI) offset may be received, for example, via RRC signaling, and may be applied to an uplink transmission of a primary stream.

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.
