摘要： A method and apparatus for facilitating a fast handoff for subscribers in a Wireless Metropolitan Area Network (WMAN) by establishing a hard association with a first entity by sending a hard association request to the first entity and receiving a hard association response in response to the hard association request and establishing a pending association with a second entity by sending a pending association request to a second entity and receiving a pending association response from the second entity. In one embodiment, the pending association with the second entity may be converted to a hard association.

摘要： An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined. A fast Fourier transform (FFT) output for the current OFDM symbol is also determined. The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified
摘要翻译：确定与先前发送的OFDM符号或当前OFDM符号相关联的多个子载波中的选定子载波相关联的干扰贡献。还确定了用于当前OFDM符号的快速傅里叶变换（FFT）输出。从当前OFDM符号的FFT输出中减去干扰贡献以形成修改

摘要： A method (300) for radio link control padding is shown. In its simplest form, it can include the steps of: providing (310) N bytes of data from a base station; interleaving (320) the N bytes of data using a turbo-interleaver; pre-pending (330) K bytes of zero padding; and passing (340) the interleaved N bytes and the pre-pended K bytes to a convolutional encoder to provide an output comprising a parity sequence adapted for further processing and providing a radio link control block for an enhanced general packet radio service 2-B mobile device. The method (300) is particularly adapted for use with Chase and incremental redundancy combining, which can provide fast, reliable and efficient general packet radio service to a 2-B mobile device.

摘要： First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.
