摘要： In a system in which the modulation scheme employed may change on a per-time-slot basis, a user's available data rate may change even if the user maintains the same number of time slots, because the capacity of the user's time slots may change. If one or more such changes in modulation scheme occurs, the data rate available to the user may no longer match his current data rate needs. Therefore, a method is disclosed for determining the number of time slots to assign to a user as a function of the user's current data rate requirement and the actual current cumulative data rate of the time slots currently assigned to the user. The user data rate requirement may further be a function of a quality of service (QoS) contracted for by the user. Thus, the assignment of the time slots within the frame is made dynamically and the number of time slots employed by a user is increased or decreased according to the user's current data rate requirements and the ability of the time slots already assigned to the user to meet those requirements.
摘要翻译：在所采用的调制方案可以在每个时隙的基础上改变的系统中，即使用户维持相同数量的时隙，用户的可用数据速率也可能改变，因为用户时隙的容量可能会改变。如果发生调制方案中的一个或多个这样的改变，则用户可用的数据速率可能不再符合他当前的数据速率需求。因此，公开了一种用于根据用户当前数据速率要求和当前分配给用户的时隙的实际当前累积数据速率来确定分配给用户的时隙数量的方法。用户数据速率要求还可以是由用户签约的服务质量（QoS）的函数。因此，动态地分配帧内的时隙，并根据用户的当前数据速率要求和已经分配给用户的时隙的能力来增加或减少用户使用的时隙数量那些要求。

摘要： In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known a priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

摘要： Parallel Decision-Feedback Decoding (PDFD) techniques which provide joint Decision Feedback Equalization (DFE) and decoding of a sequence of transmitted symbols. In an illustrative embodiment, branch metrics associated with transitions between states of a multi-stage trellis are computed. For a given stage t of the trellis, the branch metrics are computed for each of the states, using a different input value yt(s) for each state. The input values yt(s) correspond to extended survivor paths computed for each state using a DFE process. The branch metrics are utilized to determine a global most-likely path through the trellis, and the path is used to generate a decoded output signal representative of the transmitted symbol sequence. The PDFD techniques of the invention provide significant performance gains relative to conventional techniques, and are suitable for use with both PSK and QAM modulation constellations.

摘要： A method of remotely treating malicious mobile terminals connected to a mobile communications network. In one embodiment, when a malicious mobile terminal is detected by the intrusion-detection services of the network, the network changes the subscriber profile associated with the mobile terminal to operate the latter in a quarantine mode. The packet-switched subsystem of the network then links the quarantined mobile terminal to a remediation manager. The remediation manager remotely treats the mobile terminal, e.g., to repair or reinstall any corrupted software, terminate any active malicious processes, delete or quarantine any malware, and restore the operating system, configuration, and/or memory of the mobile terminal to a clean operational state. After the treatment, the network reverts the subscriber profile back to the initial state and removes the mobile terminal from the quarantine.

摘要： The invention includes methods and apparatuses for supporting mobility management and packet routing in ad hoc wireless networks. A method for mobility management includes detecting, at a first base station, a request by a wireless device to establish an association with the first base station where the first base station comprises a mobile base station, updating an association table of the first base station to include an association of the wireless device to the first base station, and propagating, toward a second base station, a message adapted to update an association table of the second base station, wherein the second base station is a mobile base station, wherein the message is propagated toward the second base station wirelessly. The packet routing functions of the present invention may be used independent of, or in conjunction with, the mobility management functions of the present invention.
