A method and apparatus for a wireless transmit receive unit (WTRU) to use a contention-based uplink communications channel, applies a rule-based restriction of access to the contention-based uplink channel that attempts to use at least one contention-free uplink channel allocation for uplink transmissions on a condition that at least one contention-free uplink channel allocation has been granted.

Method and apparatus for contention-based uplink data transmission

A method for sensing measurement gap scheduling includes allocating a new supplementary carrier in a license-exempt spectrum by a radio resource management (RRM) entity in an evolved Node B (eNB); configuring a local cognitive sensing entity in the eNB by the RRM entity; configuring a wireless transmit/receive unit (WTRU) for cognitive sensing through radio resource control (RRC) signaling, the RRC signaling being generated by the eNB; configuring a local cognitive sensing entity at the WTRU by a dynamic spectrum management (DSM) entity; and signaling a start and a duration of a measurement gap to an enhanced sensing component.

A method for increasing data rate in wireless communications includes selectively activating a plurality of hardware accelerators, and performing, using the hardware accelerators, data processing for modem data based on parameters received from a processor.

UMTS FDD modem optimized for high data rate applications

A method and apparatus for optimization of a modem for high data rate applications comprise a plurality of hardware accelerators which are configured to perform data processing functions, wherein the hardware accelerators are parameterized, a processor is configured to selectively activate accelerators according to the desired function to conserve power requirements and a shared memory configured for communication between the plurality of hardware accelerators.

An iterative turbo decoder for a wireless transmit receive unit (WTRU) of a wireless communication system and method for error correcting received communication signal data are provided. The decoder implements a stopping rule through use of signature codes to determine whether successive iterations of decoder data are the same.

A physical layer transport composite processing system used in a wireless communication system. A plurality of interconnected processing blocks are provided. The blocks are interconnected by a read data bus, a write data bus and a control bus. The blocks include a transport channel processing block, a composite channel processing block and a chip rate processing block. At least two of the blocks are capable of processing data for a plurality of wireless formats. A first set of parameters is programmed into the blocks for a particular wireless mode. The blocks are operated to process data in the particular wireless format mode.

Software parameterizable control blocks for use in physical layer processing

A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna for receiving signals from users and a pool of reconfigurable correlators. Each correlator correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller provides to an input of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor sorts output energy levels of the correlators.

Access burst detector correlator pool

A Node-B/base station receiver comprises at least one antenna for receiving signals. Each finger of a pool of reconfigurable Rake fingers recovers a multipath component of a user and is assigned a code of the user, a code phase of the multipath component and an antenna of the at least one antenna. An antenna/Rake finger pool interface provides each finger of the Rake pool an output of the antenna assigned to that Rake finger. A combiner combines the recovered multipath components for a user to produce data of the user.
