    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: In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.
