摘要： A method and apparatus are provided that dynamically allocates communication streams to provide flexible bandwidth to terminals of a communications system. In one embodiment the invention includes identifying a first terminal and a second terminal to each other for the communication of traffic over at least one of multiple streams; and dynamically allocating and de-allocating further streams based on the traffic to be carried and the traffic capacity of opened streams between the first and the second terminals. The invention may further include comparing traffic to be carried between the first terminal and the second terminal to the capacity of any open streams between the first terminal and the second terminal and allocating or de-allocating at least one stream based on the comparison. Alternatively, the invention may include comparing depths of transmit queues to the capacity of any open streams between the first terminal and the second terminal and allocating or de-allocating at least one stream based on the comparison.

摘要： A method and apparatus for delaying or hastening the “lifespan” of a session in response to detecting (or causing) a session renewal. A “session,” refers to a particular user terminal's right of access to one or more communication channels to exchange data with the base station (and other devices/networks coupled thereto). A session renewal refers to an event or condition that delays the lapse/expiration of the session lifespan (i.e., extends the lifespan) or conversely, an event or condition that causes hastens the lapse of the session lifespan (i.e., causes an earlier lapse of the session). In one embodiment, a session represents the period of time in which a user terminal is registered with a base station and can thus access or attempt to access one or more wireless communication channels to exchange data with the base station. Therefore, a session “lifespan” represents a length of time subsequent to which, upon lapse of the lifespan, the session terminates and a remote user terminal must re-register with a base station to establish a session and to gain access to one or more wireless communication channels in which data may be exchanged between the user terminal and the base station.
摘要翻译：响应于检测（或导致）会话更新而延迟或加速会话的“寿命”的方法和装置。 “会话”是指特定用户终端访问一个或多个通信信道以与基站（以及与其耦合的其他设备/网络）交换数据的权利。会议更新是指延迟会话生命周期的延迟/到期（即延长寿命）的事件或条件，或相反地，导致加速会话生命周期的延迟的事件或条件（即，导致更早的过去会议）。在一个实施例中，会话表示用户终端向基站注册的时间段，并且因此可以访问或尝试访问一个或多个无线通信信道以与基站交换数据。因此，会话“寿命”表示随后的时间长度，随后的寿命延长，会话终止，并且远程用户终端必须向基站重新注册以建立会话并获得访问一个或多个可以在用户终端和基站之间交换数据的无线通信信道。

摘要： An emergency call recognition system which is activated when an off-hook situation occurs, which recognizes when an emergency number is dialed with or without the presence of a dial tone, and which provides the caller a communication channel to complete such a call. The present invention is used to give priority to emergency telephone calls. Typically the present invention is used in wireless local loop systems, however the present invention can also be incorporated into a conventional telephone system. The present invention uses an emergency call recognition system to determine if a person is dialing an emergency telephone number. If the emergency call recognition system recognizes a dialed telephone number as an emergency telephone number, then the caller is provided with a communication channel to complete the telephone call. The caller is provided a communication channel even if all of the communication channels are in use. This is accomplished by disconnecting calls that are not of an emergency nature.

摘要： A data stream is transmitted between a base station and user terminal. A first resource that is available to transmit a page is selected at the base station and the page transmitted from the base station via the first resource. The page is received at the user terminal via the first resource and a second resource that is available to transmit a page response is selected at the user terminal. A page response is transmitted from the user terminal via the second resource in response to the page. A data stream is then transmitted between the base station and user terminal via a third resource. In one embodiment, the first, second and third resources utilize the same sequence of radio frequency resources that follow a hopping sequence among a set of available radio frequency resources. In one embodiment, at least two of the first, second and third resources utilize the same sequence of radio frequency resources. In yet another embodiment, the resources utilize different sequences of radio frequency resources.

摘要： A partial spatial signature can be determined to be used in calibration. In one embodiment, determining the partial spatial signature includes receiving a first segment of a waveform, the first segment resulting from a radio transmitting a combined signal from a first antenna element, the combined signal comprising the sum of a first signal and a second signal, and calculating a first spatial signature related measurement using the received first segment, the first signal and the second signal. The process may further include receiving a second segment of the waveform, the second segment resulting from the radio transmitting the first signal from the first antenna element, and the radio simultaneously transmitting the second signal from a second antenna element, and calculating a second spatial signature related measurement using the second received segment, the first signal, and the second signal. Then, determining the partial spatial signature may be done using the first spatial signature related measurement and the second spatial signature related measurement.

摘要： A calibration function for calibrating a base station can be determined using one or more remote terminals. In one embodiment of the present invention, determining the calibration function includes transmitting a calibration signal, using an array of antenna elements of a first radio, to a second radio, and receiving, at the first radio, a downlink spatial signature related signal from the second radio containing information related to a second radio downlink spatial signature, the information being calculated using the calibration signal. Then, a second radio downlink spatial signature may be determined using the downlink spatial signature related signal. Also, a second radio uplink spatial signature may be determined using an uplink spatial signature signal from the second radio to the first radio. The calibration function may then be determined using the second radio downlink spatial signature and the second radio uplink spatial signature. Furthermore, one embodiment of the present invention may include determining a third radio downlink weight vector for a third radio using a third radio uplink weight vector and the calibration function.
