Abstract: A method and system for utilizing smart antenna in transmission of messages between nodes (102a-102n) are disclosed. A wireless communication system includes a plurality of nodes (102a-102n), and each node is capable of being connected to each other node. At least a portion of the nodes are provided with a smart antenna (204) configured to generate a plurality of directional beams (109a-109h). Each node maintains a list of other nodes and beam configuration information to be used in transmission of messages to other nodes. When a source node is required to transmit to a target node, the source node retrieves the beam configuration information and transmits with a directional beam (109) directed to the target node.

Abstract: A first detector receives a received signal and extracts the data signals from the received signal. A hard decision converter converts soft symbols outputted by the first detector into hard symbols. An interference canceller extracts the voice signals from the received signal. A second detector is connected to the output of the interference canceller, and extracts the individual voice signals. The second detector is a different detector type than the first detector.

Abstract: A transmitting station performs closed loop power control prior to a transmission pause. A closed loop transmission power level prior to the pause is determined. A reference signal is received and a received power level of the reference signal prior to and during the transmission pause is determined. The measured reference signal received power levels are compared to a transmit power level of the reference signals to produce a pathloss estimate of the reference signal prior to and during the transmission pause. A new transmit power level is determined by adjusting the closed loop transmission power level by a change between the prior to and during pathloss estimates. A transmission power level of the transmitting station is set to the determined new transmit power level. A communication is transmitted at the set transmission power level.

Abstract: PROBLEM TO BE SOLVED: To provide a method for managing capacity in a spread spectrum communication system including a base station and a plurality of subscriber stations. SOLUTION: The base station includes the processes for: measuring the transmission power levels of a connection channel and a plurality of message channels; comparing the transmission power levels with a first prescribed power value to generate a power comparison result value; and setting a traffic connection value in the first prescribed value to interrupt the transmission of an allocated channel and the message channels of each of the subscriber stations when the transmission power level is consequently equal to or more than the prescribed power value. Each of the subscriber stations includes the processes for: allocating a transmission power level to measure a channel and a message channel; comparing the transmission power level with a second prescribed value; and displaying a maximum power state in the base station when one transmission power level is equal to or more than the second prescribed value. The base station further includes a process for interrupting the transmission of the allocated channel and message channel of each of the subscriber stations in response to the maximum power state.

Abstract: A wireless communication system and method generates and shapes one or more three-dimensional control channel beams for transmitting and receiving signals. Each three-dimensional beam is directed to cover a particular coverage area and beam forming is utilized to adjust bore sight and beam width of the three-dimensional beam in both azimuth and elevation, and the three-dimensional control channel beam is identified. In another embodiment, changes in hot-zones or hot-spots, (i.e., designated high volume user coverage areas), are managed by a network cell base station having at least one antenna. Each of a plurality of wireless transmit/receive units (WTRUs) served by the base station use a formed beam based on one or more beam characteristics. When the coverage area is changed, the base station instructs at least one of the WTRUs to change its beam characteristics such that it forms a return beam concentrated on the antenna of the base station.

Abstract: A method and apparatus for downloading and uploading digital data using a dual-mode wireless transmit/receive unit (WTRU). When in a first mode, the WTRU communicates with a first network, such as a universal mobile telecommunication system (UMTS). While the WTRU is in the first mode, a user of the WTRU may request the transfer of data to or from the WTRU, (i.e., a download or an upload). The user of the WTRU may also specify whether the data transfer is to occur when the WTRU is in the first mode, or in a second mode when the WTRU is communicating with a second network, such as a wireless local area network (WLAN). The data transfer may occur on a real-time basis or at a later time. In an alternative embodiment, predetermined criteria may be established for implementing automatic WTRU mode selection when data is transferred.
