Abstract: A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably, the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance sub channel.

Abstract: A mobile station measures at least one modulation attribute of at least one signal transmitted across a signaling path of a wireless link between the stations. Because the signal travels on the signaling path between the stations, rapid changes in the modulation attribute can be used to determine both (i) motions of the mobile station and (ii) changes in the base station or mobile station environments. The stations adjust at least one parameter affecting the performance of the wireless link to compensate for the rapid changes.

Abstract: An antenna apparatus which 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 programmable phase shifter. The phase of each antenna element is programmed for optimum reception during, for example, an idle mode which receives a pilot signal. The antenna array creates a beamformer 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. Various techniques for determining the proper phase of each antenna element are accommodated.

Abstract: A directive antenna includes plural antenna elements in an antenna assemblage. A feed network connected to the antenna elements includes at least one switch to select a state of at least one of the antenna elements to be in an active state in response to a control signal. The other antenna elements are in a passive state, electrically coupled to an impedance to be in a reflective mode. The antenna elements in the passive state are electromagnetically coupled to the active antenna element, allowing the antenna assemblage to directionally transmit and receive signals. The directive antenna may further include an assisting switch associated with each antenna element to assist coupling the antenna elements, while in the passive state, to the respective impedances. The antenna assemblage may be circular for a 360null discrete scan in 2N directions, where N is the number of antenna elements. The directive antenna is suitable for use in a high data rate network having greater than 50 kbits per second data transfer rates, where the high data rate network may use CDMA2000, 1eV-DO, 1Extreme, or other such Protocol.

Abstract: An illustrative embodiment of the present invention supports the transmission of data to a user on an as-needed basis over multiple allocated data channels. Data packets are transmitted in time-slots of the allocated data channels to corresponding target receivers without the need for explicitly assigning particular time-slots to a target user well in advance of transmitting any data packets in the time-slots. Instead, each data packet transmitted in a time-slot includes a header label or preamble indicating to which of multiple possible receivers a data packet is directed. The preamble also preferably includes decoding information indicating how a corresponding data payload of the data packet is to be processed for recapturing transmitted raw data.

Abstract: A repeater for a wireless network in which a signal radiation path provided by building wiring is used to provide spatial separation between at least two radiating points. The repeater is preferably packaged into a housing that is suitable for use as an Alternating Current-to-Direct Current (AC/DC) transformer (or wall wart). If the radiating point includes at least one antenna, the antenna may also be incorporated within the transformer housing. The radiating points can be are provided by at least two antennas, in which case the building wiring includes a coaxial cable, such for carrying video or cable signals. The building wiring may also be standard Alternating Current (AC) three wire conductor cable which may or may not be placed within building walls. In this implementation, the radiating point is determined by a matching circuit. A frequency conversion circuit can cause the radiation from at least one radiating point to occur at a carrier frequency that is different from the carrier frequency of the other radiating point.

Abstract: A method of managing the number of base station engaged in soft hand-off in a mobile communication system. The method involves manipulating a subscriber based directional antenna so as to control the number of base transceiver stations, pilot channels, beacon signals or other signals detected to be used in soft hand-off processing. The adaptive antennas are modified to manage the number of active set members, such as by manipulating direction, beamwidth, or other antenna parameters.

Abstract: A varactor based phase shifter that increases phase shift range using a lower characteristic impedance between quadrature ports than is used at its input/output ports. The circuit makes use of a four port coupler arrangement that imbeds a quarter wave impedance transformation between the input port and the quadrature ports as well as between the quadrature ports and the output port. The characteristic impedance across the quadrature ports is therefore less than the characteristic impedance across the input and output ports. In one implementation, reducing a characteristic input/output impedance of 50 to a 20 ohm quadrature port impedance results in a phase shift range increase of more than 50%.

Abstract: In a reverse link of a wireless CDMA communication system, a method of maintaining an idling mode connection between a field unit and a base transceiver station is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units and BTS, allowing power levels to be adjusted accordingly.

Abstract: A system causes a scan angle of a directional antenna to change temporarily from a current scan angle to at least one trial scan angle during reception of predetermined portions of an information carrying signal. At the trial scan angle(s), a trial metric associated with each trial scan angle is determined by the system. The system then selects a next scan angle based on the trial metrics. Examples of predetermined portions of the information carrying signal include the Power Control Bit (PCB) and certain symbol periods of the Forward Error Correction (FEC) block.
