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.

摘要： A method and apparatus for estimating the downlink signature for a remote transceiver which is part of a wireless communication system that includes a main transceiver for communicating with the remote transceiver. The main transceiver includes an array of transmit antenna elements. The method uses the remote transceiver for receiving signals when the main transceiver transmits downlink calibration signals. When the main transceiver also has a receive antenna array, the remote transceiver can transmit uplink calibration signals to the main transceiver for determining an uplink signature. The downlink and uplink signatures are used to determine a calibration function to account for differences in the apparatus chains that include the antenna elements of the arrays, and that enable downlink smart antenna processing weights to be determined from uplink smart antenna processing weights when the main transceiver includes means for smart antenna processing according to weights.

摘要： A method, communication apparatus, and machine-readable medium to transmit a downlink signal in a substantially non directional manner from a first communication station of a communication system on a first downlink conventional channel. The first communication station includes a smart antenna system having a plurality of antenna elements. The method includes providing a first set of sequential time intervals for the communication device for communication with its remote communication devices. One or more remote communication devices of the communication system known to the first communication station to be undesired remote communication devices transmit a signal on a first uplink conventional channel. The signals transmitted are received. In one version, they are received at the first communication station, and in another version, by another communication station of the communication system. The signal received are used to configure the smart antenna system for transmitting a downlink signal in a non-directional manner that includes mitigating interference towards the undesired remote communication devices on the first downlink conventional channel.

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.
