Abstract: A method and system for selecting and reselecting an antenna direction for an antenna capable of transmitting signals in one of at least two selectable directions. The average received signal-to-interference ratio is used to initially select the antenna direction. Thereafter the average received signal-to-interference ratio is monitored and the antenna direction reselected when the average received signal-to-interference ratio rises too far below the average received signal-to-interference ratio used to initially select the antenna direction for too long too often and if the antenna is not then required for a transmission that cannot be interrupted. If the average received signal-to-interference ratio drops significantly below the level used to initially select the antenna direction, then that level is reset downward. Reselection, if commenced, is repeated periodically until the antenna is required for transmission of a signal.

The structure and method can make efficient use of available transmission capacity and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a channel having located transmission capacity dedicated to the communication while connectionless communications can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The allocation of transmission capacity between the dedicated channels and the shared channel can be fixed, or can be managed to meet network or network operator requirements.

Abstract: A system and method of determining the maximum uplink transmit power of a subscriber station from a remote base station where the subscriber station reports incidents of foldback in its radio to the base station. When the base station receives the report, it reduces the maximum uplink transmit power of the subscriber station. After a period of time lapses without any reports of foldback occurring, the base station increases the maximum uplink transmit power of the subscriber station.

Abstract: A novel communication channel structure and method in a wireless communication system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and the subscriber stations are given access to a variety of channels, including at least one uplink data channel. The uplink data channel can operate in at least a random access mode and a polled access mode. The base station informs each subscriber station it serves of the current mode of the uplink channel via an associated downlink signaling channel and, in random access mode, each subscriber station is able to randomly access the shared uplink channel. In polled mode, each subscriber station waits for permission from the base station before sending data over the shared uplink channel. A method of operating the system monitors the collisions which occur on the uplink channel in random mode and/or the amount of data and/or the data's priority level and/or QoS requirements and switches the system between random and polled modes as appropriate. In polled mode, the method determines which subscriber stations should access the uplink and when.

Abstract: A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capacity and/or network resources while providing for both types of communication. Connection-like communications can be provided by a channel having allocated bandwidth dedicated to the communication while connectionless communication can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The frames can have a robustly packaged header that can be received by all subscriber stations serviced by the base station while payload data in the frame can be packaged with a level of robustness appropriate for the intended subscriber station. Different packagings can include different encoding and/or modulation of the payload data. The allocation of bandwidth between the dedicated channels and the broadcast channel can be fixed, or can be managed to meet network or network operator requirements. The structure and method can also be managed by the network operator to permit prioritization of some communications over others. In another embodiment, two or more shared channels are provided. In another embodiment, dedicated channels can be created with different amounts of bandwidth and/or can employ modulation and/or encoding selected according to the reception quality of the recipient subscriber station.

Abstract: The present invention provides a method and system for mitigating fading and/or poor reception at a receiver. The receiver includes an antenna diversity mechanism which can be operated in a variety of antenna configurations each of which can provide different reception characteristics. The receiver evaluates the reception quality of the radio signal with the antenna in a first configuration and with the antenna in at least a second configuration and selects the antenna configuration that has the best evaluated reception for use until a subsequent iteration, when the process is repeated. The antenna configurations can correspond to configurations wherein reception is favored in different directions or to configurations wherein different antennas are selected, each antenna being spaced from each other antenna. Th e method can also improve the reception of a signal transmitted by selecting an antenna configuration for transmissions which provides improved reception quality at the destination receiver.

Abstract: A system for transmitting data between stations, such as base stations and subscriber stations in a wireless telecommunications system, employs variable offsets f or its interleaving operations. By using different offsets with the interleavers, data which wou ld otherwise be synchronously aligned when transmitted from a station to many stations, or from many stations to a station, will not be aligned after interleaving has been performed. This reduces the peak to average ratio required for a transmitter and/or can reduce interference experienced at receivers in the system. This is especially true if a significant proportion of the otherwise aligned signals are symbols which require zero energy to transmit.

Abstract: The present invention provides a novel system, method and apparatus for allocating power between at least two communication services that share a common power output limit. Two communication services particularly suited for the present invention are voice services and data services transmitted on the downlink of a wireless network. An embodiment of the method includes determining the actual consumption of power on the voice channels of the wireless network during a given time period, and allocating substantially th e same amount of power to the voice channels for the next time period, thus allowing for the allocation of the remaining amount of power to the data services, and thereby allowing, for example, increased modulation of the data services and thereby improve overall rates of data transfer and/or reliability of data transmission.
