    Abstract: A wireless communication node, such as a repeater, including a frequency translating repeater, a physical layer (PHY) repeater, time divisional duplex repeater (TDD) and the like, is configured with a pair of directional patch antennae and an omni-directional antenna. The patch antennae can be selected depending on the orientation of the repeater package to communicate with a station such as an access point or a base station. The omni-directional antenna can be directed toward another station such as a client. The patch antennae and the omni-directional antenna can be orthogonally polarized to increase isolation and reduce electromagnetic coupling. Multiple antennae can be used in multiple-input-multiple-output (MIMO) configurations.

    Abstract: A subscriber controlled registration protocol, a subscriber monitors a congestion indicator signal broadcasted by a base station with which it desires to register. If the congestion indicator signal indicates that the base station is operating in a congested state, the mobile station selects another base station in the system. Otherwise, it attempts to register with the first selected base station.

    Abstract: A frequency translating repeater (200) for use in a time division duplex radio protocol communications system includes an automatic gain control feature. Specifically, a received signal (330) is split to provide signal detection paths (331, 332) wherein detection is performed by amplifiers (301, 302) filters (311, 312), converters (313, 314) and a processor (315). Delay is added using analog circuits such as SAW filters (307, 308, 309, 310) and gain adjustment provided by gain control elements (303, 304, 305, 306).

    Abstract: Session services are employed in a networked computing environment to apply specific processing to an exchange of data between processes. In a wireless communication network, a single wireless link is typically shared among multiple users through wireless channels, which are allocated and switched among the users on a demand basis. Packets sent over the wireless link need to be signaled and tagged accordingly to initiate and employ the session service for the intended packets which comprise the flow. A method for identifying and applying session services to a wireless link includes identifying a packet flow over the wireless link corresponding to a received message by employing a flow identifier and filter. The packet flow corresponds to a session, and is mapped to at least one session service. The mapped session service is then applied to the received message. A session service may therefore be transparently applied to a packet flow over a wireless link independently of the other packet flows which may also be transmitted over the wireless link.

    Abstract: An antenna apparatus that can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective signal control component such as a phase shifter. The phase shift for each antenna element is programmed for optimum reception during, for example, an idle mode when a pilot signal is received. The antenna array creates a beam former for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. The phase shifters are adjusted in a coarse and a fine mode. In the coarse mode all phase shifters are jointly incremented through several phase shift values until a signal quality metric is optimized. The coarse adjustment mode is followed by a fine adjustment mode during which the phase shifters are independently adjusted to further optimize the signal quality metric.

    Abstract: A technique for encoding a signal used in a digital communication system in which individual traffic channel data rates may be adapted to specific channel conditions. In particular, a forward error correction coding rate is adapted for individual channels while at the same time maintaining a fixed block size independent of the FEC coding rate. This allows the system data rate to adapt to the channel conditions experienced by a specific user. Thus, users experiencing good communication conditions with low multipath distortion may be allocated higher capacity, whereas users with significant multipath distortion may make use of lower rate (higher levels of coding) error codes to maintain high quality. Messages are sent from a transmitter to a receiver to inform the receiver of the coding rate implemented at any given point in time. These parameters may be adjusted independent of transmitted power level through the expedient of ensuring that size of a transmitted frame remains constant, while permitting the ability to change FEC coding rates and FEC block sizes.
