摘要： Systems and methods for avoiding access point transmission rate fall-back mechanism having an avalanche effect when acknowledgements are not received for packets sent during co-existence of WLAN and other wireless network technologies. A receiver (210, 300) comprises at least two dissimilar network technology subsystems (340). In some embodiments, a transmitter (220) transmits a handshake to the receiver prior to transmission of at least one data packet and does not reduce a transmission rate of future transmissions to the receiver if the transmitter does not receive a reply to the handshake. In other embodiments, the receiver is able to send an indicator to a transmitter requesting a protection mechanism be employed prior to transmission by the transmitter of at least one data packet. In further embodiments, the receiver is able to negotiate with the transmitter for the transmitter to employ a protection mechanism prior to transmission of at least one data packet to the receiver.

摘要： Apparatus and methods for accessing a wireless telecommunications network by transmitting a random access signal. The random access signal includes a random access preamble signal selected from a set of random access preamble signals constructed by cyclically shift selected root CAZAC sequences. The random access signal may be one or more transmission sub-frames in duration, the included random access preamble sequence's length being extended with the signal to provide improved signal detection performance in larger cells and in higher interference environments. The random access signal may include a wide-band pilot signal facilitating base station estimation of up-link frequency response in some situations. Each of the plurality of available random access preamble sequences may be assigned a unique information value. The base station may use the information encoded in the random access preamble to prioritize responses and resource allocations. Random access signal collisions are dealt with by a combination of preamble code space randomness and back-off procedures.
摘要翻译：通过发送随机接入信号来接入无线电信网络的装置和方法。随机接入信号包括从循环移位选择的根CAZAC序列构成的一组随机接入前导码信号中选择的随机接入前导码信号。随机接入信号可以是持续时间中的一个或多个传输子帧，所包含的随机接入前同步码序列的长度随信号扩展，以在更大的小区和更高的干扰环境中提供改进的信号检测性能。随机接入信号可以包括宽带导频信号，有助于在某些情况下基站估计上行链路频率响应。多个可用随机接入前同步码序列中的每一个可被分配唯一的信息值。基站可以使用在随机接入前导码中编码的信息对响应和资源分配进行优先级排序。随机接入信号冲突由前导码空间随机性和退避程序的组合来处理。
