Abstract: A solution for providing an improved fading margin environment for in-building wireless coverage. An optical fiber or other available broadband signal distribution network is used to distribute signals between centrally located base transceiver station (BTS) equipment and remotely located transceiver equipment referred to herein as a cable microcell integrator (CMI). The CMIs are deployed in a configuration to provide radio frequency coverage in a desired microcell area such as a building floor. In a preferred embodiment, a leaky coaxial cable is used as a radiating element within the microcell.

Abstract: A multiplication circuit 152 multiplies signals, which are subjected to variable directional transmission, by weighting factors with respect to the respective antennas 101 to 103, and outputs the resultant to combining circuits 155 to 157, respectively. The signals input to the combining circuit 155 are combined and radio modulated by a radio section 104, and transmitted from the antenna 101. Whereby, in a case where variable directional transmission is performed with respect to only some terminal apparatuses, signals, which are subjected to no variable directional transmission, can be transmitted after spreading them from the respective antennas of an array antenna.

Abstract: Apparatus, and an associated method, facilitates service degradation in a radio communication system, such as a cellular communication system. A service degradation profile is created, associated with a particular communication service-type, and includes values of QoS (quality of service) level values. If communication at levels corresponding to the values of the desired QoS level parameters is unavailable, efforts are made to effectuate, or maintain communication at quality levels corresponding to values of at least first QoS level parameters values. Service degradation thereby occurs pursuant to a selected profile, reducing the need for service renegotiations and reducing the possibility that an abrupt termination of a communication session might occur.

Abstract: A first wireless node provides a method of avoiding multiple access collision in a wireless network. The system receives a request to send data from a second wireless node (405) and determines if the system is receiving data from a third node (410). The system transmits a non-authorization message if the system is receiving data from the third node (415). If, however, the system is not receiving data from the third node, the system transmits an authorization message to the first wireless node (420). The system receives data from the second node in response to the authorization message (425) and then transmits an acknowledgment message to the second node acknowledging receipt of the data (435).

Abstract: In idle handover control, the reception quality of a synchronized pilot channel is classified into quality class “1” with which data can be received without any error, quality class “2” with which data can be received within an allowable error range, or quality class “3” with which data is difficult to receive with high quality, and different thresholds, i.e., 6 dB, 4 dB, and 2 dB, are respectively set for these quality classes. It is checked whether the reception quality of another pilot channel as a synchronization establishment candidate is higher than that of the synchronized pilot channel by a threshold corresponding to a quality class into which the synchronized pilot channel is classified or more. If it is determined that the reception quality of the synchronization establishment candidate is higher by the threshold or more, handover processing is performed. Otherwise, synchronization with the synchronized pilot channel is maintained without handover processing.

A transmission power control information calculator 16 calculates a transmission power control information so that SIR of the reception signal approaches a necessary SIR.

Abstract: A method and apparatus for improving loop stability and speed of a power control loop. Adjacent channel interference in the ramp-up and ramp-down (transient) of a TDMA burst is reduced. The present invention is used in a burst when the transient response and loop speed are important in the design of the control loop. The loop bandwidth variation resulting from linear conversion power detector and PIN diode RF attenuators in the loop is reduced by reducing the upper end of the loop bandwidth and increasing the lower end of the loop bandwidth. The upper limit of the loop bandwidth determines the loop stability and the lower limit of the loop bandwidth determines the minimum speed of the loop. A reference signal is sampled and processed to set a gain of a feedback loop in the power control loop.

Abstract: Fixed access wireless networks generally includes a grouping of cells, with each cell comprising a base transceiver station in radio frequency contact with a plurality of terminal stations. Such networks are typically assigned a limited number of frequencies to facilitate data transfer. Various techniques are used to maximize the amount of data which can be transferred including polarization, modulation and frequency reuse. A Local Multi-point Distribution System (LMDS) is a form of fixed wireless network, a notable feature of which are the directional nature of their terminal station antennae. The present invention provides a method of assigning frequencies to an LMDS, by exploiting the directivity of the fixed terminal station antennae. Each cell is divided into an even number of at least four sectors. Given a desired carrier to interference ratio, the cells are grouped into clusters, the cluster size defining the interference boundary for a given cell in the cluster.

Abstract: Tone sequences in a frequency hopping arrangement are generated and assigned by advantageously employing a combination of a sequence generator and a sequence assignor to generate sequences and assign them on a time slot by time slot basis. In a transmitter, the sequence generator and sequence assignor, in combination with a user tone assignor are employed to generate and assign tone sequences to a user on a time slot by time slot basis. In a receiver, the sequence generator and sequence assignor, in combination with a user tone identifier are employed to generate sequences and to identify incoming tone sequences to a user on a time slot by time slot basis. Specifically, the sequence assignment in a time slot is such that a prescribed plurality of sequences is assigned to a particular user.

Abstract: A method and apparatus for synthesizing high-frequency signals, such as wireless communication signals, includes a phase-locked loop (PLL) frequency synthesizer with a variable capacitance voltage controlled oscillator (VCO) that has a discretely variable capacitance in conjunction with a continuously variable capacitance. The discretely variable capacitance may provide coarse tuning adjustment of the variable capacitance to compensate for capacitor and inductor tolerances and to adjust the output frequency to be near the desired frequency output. The continuously variable capacitance may provide a fine tuning adjustment of the variable capacitance to focus the output frequency to match precisely the desired frequency output. During fine tuning adjustment, the PLL may be controlled by a plurality of analog control signals. The analog control signals may be derived by first generating a plurality of phase shifted signals from a divided version of the VCO output clock.
