摘要： 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 processes 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.

摘要： A method for network coding of packets between End Nodes (ENs) and a Relay Node (RN) in wireless communications can be performed at the RN. This method may include: receiving a new packet at the RN from one of the ENs; determining the source node of the new packet at the RN; providing a buffer for each EN; determining whether the buffer associated with the EN that is not the source of the new packet (non-source buffer) has the new packet buffered and based upon such determination, either: (1) storing the new packet in the EN buffer that is the source of the new packet on a condition that the non-source buffer is empty; or (2) network coding the new packet with an existing packet in the non-source buffer.

摘要： A wireless communication apparatus which uses fast Fourier transforms (FFTs) in an orthogonal frequency division multiplexing (OFDM) receiver which incorporates a beam space antenna array. The beam space antenna array may be implemented with a Butler matrix array. The beam space antenna array may be a circular array, vertical array, or a combination of both circular and vertical arrays, for providing the desired angular antenna coverage. In one embodiment, the antenna array is optimized because the FFTs are linear invariant transform operators, whereby the order of operations in the OFDM receiver can be interchanged.

摘要： A method for secure direct link communications between multiple wireless transmit/receive units (WTRUs). The WTRUs exchange nonces that are used for generating a common nonce. A group identification information element (GIIE) is generated from at least the common nonce and is forwarded to an authentication server. The authentication server generates a group direct link master key (GDLMK) from the GIIE to match WTRUs as part of a key agreement group. Group key encryption key (GKEK) and a group key confirmation key (GKCK) are also generated based on the common nonce and are used to encrypt and sign the GDLMK so that base stations do not have access to the GDLMK. Also disclosed is a method for selecting a key management suite (KMS) to generate temporal keys. A KMS index (KMSI) may be set according to a selected KMS, transmitted to another WTRU and used to establish a direct link.

摘要： A medium access control (MAC) entity first computes an achievable rate region based on a total transmit power limit and a channel gain of each of a plurality of WTRUs. Next, the MAC entity selects an order of DPC among the WTRUs. A rate set for use in transmitting to the WTRUs is then selected, said rate set being within the computed achievable rate region. Then, based on the selected DPC order and rate set, a DPC entity performs DPC on a plurality of data streams intended for the plurality of WTRUs. If nested lattice-based DPC is utilized, rate compatibility is achieved by selecting proper nesting ratios corresponding to a desired data rate set. Otherwise, if binary-code based DPC is utilized, rate compatibility is achieved via selecting appropriate message input sizes for input to point-to-point coding units prior to performing DPC.

摘要： A wireless transmit receive unit (WTRU) and methods are used in a wireless communication system to process sampled received signals to establish and/or maintain wireless communications.

摘要： Data estimation is performed in a wireless communication system using both oversampling and multiple reception antennas. A receive vector is produced for each antenna at a sampling interval which is a multiple of the chip rate of the received signal. A channel response matrix is produced for each antenna at a preferred multiple of the sampling rate. Each receive vector is processed using a sliding window based approach, where a plurality of successive windows are processed. For each window, a combined circulant channel response matrix is produced using the channel response matrices. Using the combined circulant channel response matrix and a combined received vector comprising each received vector in a discrete Fourier transform based approach to estimate a data vector corresponding to that window; and combining the data vector estimated in each window to form a combined data vector.

摘要： A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

摘要： A method and wireless communication apparatus for receiving a plurality of communication signals transmitted in a wireless code division multiple access format. A channel response for each received communication signal is estimated. A system response matrix using codes and the channel responses of the received communication signals is constructed. The system response matrix is used in connection with matched filtering the received communication signals and to produce an objective matrix. The filtered communication signals are processed in a cancellation feedback loop to produce a set of symbols of the received communications including iterative processing with an interference cancellation matrix and processing with a feedback interference construction matrix. Preferably, the objective matrix is functionally related to the interference cancellation matrix and the feedback interference construction matrix.
