摘要： A transceiver comprising a data processing module, a security processing module, a medium access control (MAC) module, a dirty-paper-coding (DPC) module, and a smart antenna processor. The data processing module provides user data streams to the MAC module and channel state information to the smart antenna processor. The security processing module generates security data and provides the security data to the MAC module. The security module also provides security policy data to the smart antenna processor. The MAC module determines data transmission rates for the user data streams and the security data. In addition, the MAC module allocates the data streams and security data to transmission channels for transmission. The DPC module encodes the security data onto the user data streams. The smart antenna processor generates pre-coding coefficients used by the DPC module and transmits the security encoded data streams.

摘要： The present invention is related to a method and apparatus for enhancing security of communications. The apparatus comprises a security processing unit, a data processing unit, a cross-layer watermarking unit, and optionally a smart antenna processor. The security processing unit generates a token/key to be used in watermarking and sends a node security policy to other components. The data processing unit generates user data. The cross-layer watermarking unit includes at least one of Layer-2/3, Layer-1 and Layer-0. Each layer performs a different scheme or degree of watermarking. The cross-layer watermarking unit embeds the token/key into the user data transmission on at least one of the layers selectively in accordance with a security policy.

摘要： Sub-carriers are allocated among the plurality of users in the OFDM system based on normalized channel gain values. Then, data bits are allocated for transmission on the allocated sub-carriers based on incremental transmission cost values. The channel gain values and the incremental transmission cost values are computed using a calculated fairness factor for each user in the system.

摘要： A transmission power level of a selected user is estimated in a code division multiple access (CDMA) communication system. An initial estimate of a transmit power level associated with the selected user is determined. A transmit power level of users of the system other than the selected user is provided. Subsequent estimates for the selected user and the other users are estimated using previous transmit power level estimates of the selected user and the other users. The estimating subsequent estimates is repeated with a last repetition's estimated transmit power levels for the selected and other users being the estimated transmit power levels of the selected and other users.

摘要： A call admission control (CAC) method which operates in a network including at least one target cell and a plurality of neighboring cells under a variety of conditions. When only common measurements are available, the CAC function at a Controlling Remote Network Controller (CRNC) determines whether to accept or reject a request to setup or reconfigure a radio access bearer based on common measurements of the target cell and neighboring cells, estimated common measurements after admission, and load measurements of the target cell and the neighboring cells. When no measurements are available, the CAC function at the CRNC determines whether to accept or reject the request based on estimated load of the target cell and neighboring cells. The load is estimated based on the signal-to-interference ratio (SIR) of the requested radio access bearer, and the SIR of existing coded composite transport channels (CCTrCHs) in the target cell and neighboring cells.

摘要： A method and system for performing call admission control in wireless communication systems is disclosed. Resource units required by a new user are assigned based on an outage probability of each uplink timeslot. The outage probability of each timeslot is updated as the resource units are assigned so that each resource unit assignment results in the lowest possible contribution to total outage probability. Once all of the resource units are assigned, the total outage probability is computed based on the resource allocation. If the total outage probability is below a predetermined value, the new user is admitted. If the total outage probability is above the predetermined value, the new user is rejected.

摘要： A wireless communication system, which supports enhanced dedicated channel (E-DCH) data transmissions, includes a wireless transmit/receive unit (WTRU), at least one Node-B and a radio network controller (RNC). The WTRU includes a buffer, a data lifespan timer, a data retransmission counter, a hybrid-automatic repeat request (H-ARQ) process and a controller. The timer establishes a lifespan for at least one data block stored in the buffer. If physical resources have not been allocated for a data block associated with a lifespan timer that is close to expiration, the WTRU sends an urgent channel allocation request. If physical resources have been allocated, the data block is prioritized for transmission with respect to other data blocks. The data block is discarded if the lifespan timer expires or if the WTRU receives feedback information indicating that the data block was successfully received by the Node-B.
