International Classification:

H04W 52/52
H04W 72/02

US Classification:

370329

Abstract:

Systems, methods, and instrumentalities are disclosed herein to determine a gain factor. A user equipment (UE) may determine that an S-E-DPCCH and an E-DPCCH are to be transmitted on a primary stream. The UE may calculate an E-DPCCH gain factor using a gain factor calculation and apply the -DPCCH gain factor. The UE may calculate an E-DPCCH gain factor reduction. For example, the E-DPCCH gain factor reduction may compensate for changes from single stream transmission to multiple stream transmission. The UE may apply the E-DPCCH gain factor reduction to the E-DPCCH gain factor. The UE may apply the E-DPCCH gain factor reduction to an S-E-DPCCH gain factor.

International Classification:

H04W 72/04

US Classification:

370329

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.

International Classification:

H04W 72/04

US Classification:

370329

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.

International Classification:

H04J003/12
H04L027/06
H03D001/00

US Classification:

375/340000, 370/526000

Abstract:

A tone detection device is provided which includes a Fourier Transform means for performing a Fourier Transform on an incoming signal. The Fourier Transform means generates a frequency spectrum of the incoming signal. A normalizing means receives the generated frequency spectrum and normalizes the spectrum for magnitude. The normalizing means then generates a normalized frequency spectrum. An integrator means receives the normalized frequency spectrum and generates a mean of the normalized frequency spectrum over time. A comparator means then determines whether the mean of the normalized frequency spectrum exceeds a predetermined threshold value. If so, a signal is generated indicating that a tone is detected. If the mean of the normalized frequency spectrum does not exceed the predetermined threshold value, a signal is generated indicating that no tone is detected.

International Classification:

H04L 5/00
H04W 72/04

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.
