    Abstract: A wireless communication method and system for assigning multi-paths to Rake receiver fingers. A Rake finger assignment database is established in which multi-path signals (300) are categorized into a verified group and an unverified group. Each multi-path is assigned to an individual bin in the database. Each bin includes a pilot phase data field (310), an antenna data field (315), a code data field (320), an averaged signal strength data field (325), an assigned flag data field (330), a verification flag data field (335), an update flag data field (340), an assigned Rake finger number data field (345) and an assignment time counter data field (350). The multi-path signals in the verified group are further categorized into an assigned subgroup and an unassigned subgroup. During a measurement interval, each of a plurality of newly measured multi-path signals is compared to the multi-path signals in the database and is processed accordingly.

    Abstract: Received signal characteristics of multiple concurrently received channels are determined using an analytical approach for computation. A receiving wireless transmit receive unit and method are provided for processing concurrent communication signals from a plurality of transmitting WTRUs (50k) that concurrently transmit successive data blocks in a plurality of K forward channels. The receiving WTRU (70') preferably has a receiver (86) configured to receive successive data blocks of K concurrent transmissions transmitted from the transmitting WTRUs (50k) on the respective K forward channels. The processor (55k) is configured to successively compute instantaneous signal to interference ratio values for each forward channel j, for integers j=1 to K, based on a cross correlation matrix of channel response characteristics of K concurrently received data blocks and to selectively compute an average value that is used for the computing the individual channel characteristics for the forward channel K. The individual channel characteristics are advantageously used for power control or for the processing of the data blocks received on the respective forward channels.

    Abstract: A method and system for generating a secret key from joint randomness shared by wireless transmit/receive units (WTKUs) are disclosed. A first WTRU and a second WTRU perform channel estimation to generate a sampled channel impulse response (CIR) on a channel between the first WTRU and the second WTRU. The first WTRU generates a set of bits from the sampled CIR and generates a secret key and a syndrome, (or parity bits), from the set of bits. The first WTRU sends the syndrome, (or parity bits), to the second WTRU. The second WTRU reconstructs the set of bits from the syndrome, (or parity bits), and its own sampled CIR, and generates the secret key from the reconstructed set of bits.

    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: A method and system for securing wireless communications is disclosed. In on embodiment, different security policies are used based on the distance between a receiver and a transmitter, whereby data in the wireless communications can only be demodulated if received in particular trust zones. In another embodiment, a plurality of bit stream fragments are transmitted by a plurality of transmitters to a receiver located in an area where transmission patterns radiated by the transmitters intersect. Alternatively, the receiver performs a function on packet data units (PDUs) transmitted by the transmitters. In yet another embodiment, primary modulation points of a modulation points which can be demodulated only by a receiver that is within range of the transmitter. In yet another embodiment, a main waveform is transmitted which overlays a QPSK signal with hierarchical modulation (HM) having encoded descrambling information.
