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： A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.

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.
摘要翻译：媒体接入控制（MAC）实体首先基于多个WTRU中的每一个的总发射功率限制和信道增益来计算可实现速率区域。接下来，MAC实体在WTRU中选择DPC的顺序。然后选择用于向WTRU发送的速率集，所述速率集合在所计算的可实现速率区域内。然后，基于所选择的DPC顺序和速率集合，DPC实体在为多个WTRU设置的多个数据流上执行DPC。如果利用嵌套的基于网格的DPC，则通过选择对应于期望的数据速率集合的适当的嵌套比率来实现速率兼容性。否则，如果使用基于二进制码的DPC，则在执行DPC之前通过选择适当的消息输入大小来输入到点对点编码单元来实现速率兼容性。

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.

摘要： A wireless communication method and apparatus for coordinating Node-Bs during handover for enhanced uplink (EU) transmission. In one embodiment, a radio network controller (RNC) initiates an inter-Node-B soft handover. A wireless transmit/receive unit (WTRU) establishes communication connections with a plurality of Node-Bs. A particular one of the Node-Bs is designated as being a primary Node-B, and each of other Node-Bs are designated as being a non-primary Node-B. The RNC informs all of the Node-Bs that the particular Node-B is a primary Node-B. The primary Node-B schedules EU transmission and performs ACK/NACK during soft handover. In another embodiment, the RNC initiates a hard handover for a WTRU connected to a source Node-B. The RNC sends an activation timer to the source Node-B to set the time for handover. As many previously negatively acknowledged (NACKed) data packets as possible are prioritized for retransmission in the source Node-B before the activation timer expires.

RNC通知所有的节点B该特定的节点B是主节点B. 主节点B调度EU传输并在软切换期间执行ACK / NACK。在另一个实施例中，RNC为连接到源节点B的WTRU发起硬切换。 RNC向源节点B发送激活定时器以设置切换时间。由于在激活定时器到期之前，许多以前否定确认（NACK）的数据分组被优先重新排列在源节点B中。

摘要： A method and apparatus is used for generating a perfectly random secret key between two or more transceivers in a wireless communication network. In a point- to-point system, both transceivers produce an estimate of the channel impulse response (CIR) based on the received radio signal. The CIR estimation is synchronized and may include error correction and detection. A long secret key of bits is generated from a digitized version of the CIR estimate, from which a perfectly secret encryption key is derived by privacy amplification.

摘要： A method and apparatus for efficient operation of an enhanced dedicated channel (E-DCH) are disclosed. A physical layer processing includes computation of various control parameters followed by actual processing of the data to be transmitted. In accordance with the present invention, the computation of the control parameters is performed asynchronously from the associated data operation. A medium access control (MAC) layer provides information needed for computation of the control parameters to the physical layer as early as possible, while the data is being processed in parallel. The provided data includes a hybrid automatic repeat request (H-ARQ) profile, a transport block size, power offset, or the like. By sending this data to the physical layer before MAC-e processing is complete, the latency constraint can be significantly relaxed.
