Abstract: A protocol engine (PE) for processing data within a protocol stack in a wireless transmit/receive unit (WTRU) is disclosed. The protocol stack executes decision and control operations. The data processing and re-formatting which was performed in a conventional protocol stack is removed from the protocol stack and performed by the PE. The protocol stack issues a control word for processing data and the PE processes the data based on the control word. Preferably, the WTRU includes a shared memory and a second memory. The shared memory is used as a data block place holder to transfer the data amongst processing entities. For transmit processing, the PE retrieves source data from the second memory and processed the data while moving the data to the shared memory based on the control word. For receive processing, the PE retrieves received data from the shared memory and processes it while moving the data to the second memory.

Abstract: An adaptive equalizer including an equalizer filter and a tap coefficients generator used to process a sample data stream derived from a plurality of received signals is disclosed. The tap coefficients generator includes an equalizer tap update unit, a vector norm square estimator, an active taps mask generator, a switch and a pilot amplitude reference unit used to minimize the dynamic range of the equalizer filter. A dynamic mask vector is used to mask active taps generated by the equalizer tap update unit when an unmasked signal output by the equalizer filter is selected by the switch to generate an error signal fed to the equalizer tap update unit. A fixed mask vector is used to mask active taps generated by the equalizer tap update unit when a masked signal output by the equalizer filter is used to generate the error signal.

Abstract: A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) (110, 115, 120) and an access point (AP) (105). The AP communicates with the WTRUS via an antenna. In one embodiment, the AP configures the antenna to a wide beam configuration that covers a desired service area and transmits a Request-To-Send (RTS) control message. When the AP receives a Clear-To-Send (CTS) from one of the WTRUs, the AP determines optimal antenna settings for communication with the one WTRU. The AP configures the antenna to a narrow beam configuration and transmits at least one data packet to the one WTRU. When the AP receives an acknowledgement message indicating that the data packet was successfully received by the WTRU, the AP configures the antenna to the wide beam configuration. In another embodiment, the AP is configured to transmit and receive data packet fragments from the WTRUs and configure the antenna accordingly.

Abstract: The present invention is related to a method and system for providing a wireless transmit/receive unit (WTRU) (10) status, in providing real time services via a wireless local area network interworking with 3GPP systems (20). An entity such as a packet data gateway (PDG) (24) in the 3GPP network stores and maintains the current state of the WTRU and updates the state of the WTRU when it changes. The WTRU signals a change in its state to the PDG. When the PDG receives a message from the 3GPP system directed to the WTRU, the PDG examines the status of the WTRU prior to forwarding the message to the WTRU.

Abstract: The method involves sending a request frame to a responder by an initiator, and sending a response frame to the initiator without sending a separate acknowledgement (ACK) frame for acknowledging receipt of the request frame. The response frame is sent by the responder within a short inter-frame spacing (SIFS) from time that the responder receives the request frame, where the responder has a request identity number in the response frame. An independent claim is also included for a wireless communication system comprising an initiator.
