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, communication device, and machine-readable medium. The method includes sending a first poll from a first base station having a smart antenna system to a first user terminal. The first base station receives a first uplink response signal from the first user terminal as a result of the first user terminal successfully receiving the first poll. The first base station also receives at least one other uplink response signals as a result of at least one other remote user terminal successfully receiving a second poll from a second base station. The first base station transmits downlink data to the first user terminal using a downlink smart antenna processing strategy for transmitting to the first user terminal, including mitigating interference to the first and one or more other remote communication devices from which the first base station received a first or other uplink response signal and that may be receiving during transmission of downlink data to the first user terminal. The downlink smart antenna processing strategy is using the first and other received uplink response signals. The first base station uses a first protocol with its associated user terminals and the second base stations uses a second protocol that is coordinated with the first protocol to enable the first base station to receive the first and other uplink response signals from second and one or more other remote communication devices that may be receiving during the step of transmitting downlink data to the first user terminal.

摘要： A method for generating a reference signal from a modulated signal transmitted to a communications station that includes an array of antenna elements and spatial processing means including: separating from the signals received at the antenna elements a copy signal corresponding to the signal transmitted by a particular remote station using an initial spatial weight vector corresponding to the particular remote station; determining from the terminal copy signal a reference signal having substantially the same frequency offset and time alignment as the received antenna signals; and computing a new spatial weight vector by optimizing a cost function, the cost function using the received antenna signals and the reference signal. For demodulation, the method further includes extracting the symbols of the modulated signal.

摘要： Channels are assigned based on co-spatial constraints in wireless network using spatial division multiple access. In one example, the invention includes assigning a co-spatial constraint to each of a plurality of conventional traffic communications channels of a base station, and receiving a request from a user terminal to communicate using a traffic communication channel of the base station. The invention further includes measuring a quality parameter of the request deriving a co-spatial constraint for the user terminal, assigning the user terminal co-spatial constraint to the user terminal, and assigning the user terminal to a traffic communication channels having a channel co-spatial constraint that is no less than the user terminal co-spatial constraint and that has no more assigned radios than permitted by the channel co-spatial constraint.

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： A method and apparatus is described for modifying a smart antenna processing strategy determined from a set of signals received at an array of antenna elements of a wireless station, such as a set of weights for processing received antenna signals or forming a set of antenna signals for transmission. The method and apparatus uses the signatures of one or more interferers to produce a modified processing strategy that improves the nulling to the one or more interferers in that, when the modified strategy is applied on the downlink, the transmit signal strength in the direction of the one or more interferers is decreased, and, when the modified strategy is applied on the uplink, the sensitivity to signals from the direction of the one or more interferers is decreased.

摘要： The present invention is a method for operating a base station (BS) for transmitting information to a subscriber unit (SU) in a cellular communication system. The information is included in a downlink signal sent from a signal processing circuit through an array of antennae. The processing depends on a weight set that is utilized in generating individual signals to be sent on individual antennae in the array to the SU. The weight set is determined by transmitting a plurality of pilot downlink signals from BS to the SU, each pilot downlink signal being processed with a different weight set than that used to process the other pilot downlink signals. Report signals are received for each of the pilot downlink signals and are compared to determine which weight set should be utilized. The present invention may be practiced within existing CDMA cellular standards such as the IS-95 standard.
