Abstract: A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

Abstract: A base station includes a wireless transceiver for establishing a communication session over a first digital communication path, and a bandwidth management module is connected to the wireless transceiver for allocating at least one code channel within the at least one radio frequency channel for exchanging digital signals over the first digital communication path during the communication session. The at least one code channel may include at least one traffic portion that is established for a predetermined time and at least one control portion that is continuously available.

Abstract: A code division multiple access (CDMA) user device includes a CDMA transceiver, and a controller connected to the CDMA transceiver for establishing a communication session with a base station. The communication session includes a plurality of layers including a physical layer. The controller negotiates with the base station for an allocated bandwidth for the CDMA transceiver. The controller also establishes and releases a physical layer connection between the CDMA transceiver and the base station, and maintains a state of at least one other layer during the communication session after termination of the physical layer.

Abstract: A subscriber access unit for transferring session context in wireless communication is disclosed. The access unit contains first context establishing circuitry for establishing a first wireless session context associated with a first wireless coverage area; locating circuitry for determining whether the subscriber access unit is located concurrently in the first wireless coverage area and a second wireless coverage area; loading factor receiving circuitry for receiving a first loading factor and a second loading factor indicative of a throughput load associated with the first and second coverage areas respectively; comparison circuitry for comparing the first loading factor with the second loading factor; and second context establishing circuitry for selectively establishing a second wireless session context continuous with the first wireless session context, the second context associated with the second wireless coverage area, based on output of the circuitry comparing the first and second loading factors.

Abstract: A system for wireless data transmission that uses a channel bandwidth, channel separation, and radio frequency power spectrum which is compatible with existing deployments of wireless voice services. The transmitted waveforms are thus compatible with existing cellular networks. However, the time domain digital coding, modulation, and power control schemes are optimized for data transmission. Existing cellular network sites can thus be used to provide a high speed service optimized for wireless data traffic without the need for new radio frequency planning, and without interfering with existing voice service deployments.

Abstract: A method for operating a CDMA user device includes establishing a communication session with a base station. The communication session includes a plurality of layers including a physical layer. A service configuration is negotiated with the base station, and the user device receives an assigned subchannel from the base station. A physical layer connection is established with the base station on the assigned subchannel. The physical layer connection corresponds to the physical layer. The method further includes releasing the assigned subchannel so that the physical layer connection is terminated, and maintaining a state of at least one other layer during the communication session after termination of the physical layer.

Abstract: A technique for coordinating the operation of subscriber units such as in a wireless communications system so that high-probability-of-interference communications do not take place at the same time in adjacent cell sites. A base station becomes aware of expected periods or time slots of high relatively expected interference from remote units operating in a neighboring cell site, and then schedules only low interference level transmissions for its own remote units during such periods. Expected interference information ca be exchanged by base stations directly, through a centralized base station controller-initiated schedule, or by relaying resource load status messages via remote units located near all boundaries.

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 Forward Error Correction (FEC) block.

Abstract: In a wireless communication network, a system and method for transferring a wireless session context allows a subscriber access unit to transfer the session context from one base station to another base station depending on a loading factor which indicates the throughput load through each of the base stations. A subscriber access unit which is located in an overlapping wireless coverage area served by both base stations can transfer the session context such that it is served by the base station having the least throughput load. Subscriber access units in overlapping coverage areas will therefore tend to transfer session context to the least burdened base station processor. In this manner, performance is improved because subscriber access units within a wireless coverage area of multiple base station processors are transferred to the base station able to provide the maximum throughput.
