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.

H04Q 720

455452, 455500, 455450, 370468

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.

H04J 1300

370335

A technique for implementing a sublayer of a protocol suitable for data transfer in a multichannel environment where each channel is assumed to be prone to a significant bit error rate such as in a wireless communication system. The invention may be used to provide a high speed data transfer such as at 128 kilobits per second or higher with a bit error rate of 10. sup. -6 or better using multiple channels. By keeping track of the number of frames received in error, the sender dynamically adjusts the subframe size for each channel to optimize the effective overall throughput. The subframes each carry preferably two types of sequence numbers including a position number related to an index into a larger frame to be transmitted as a single data entity. The second sequence number is related to the subchannel used so that the receiver can detect missing subframes. This then enables the receiver to submit retransmission requests for the missing pieces which can then be transmitted on the same channel or on another channel.

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. The bandwidth management module may reallocate the at least one traffic portion from the first digital communication path to a second digital communication path if an extension of time is not requested from the base station over the first digital communication path for the at least one traffic portion, or if the base station no longer has digital signals to transmit over the first digital communication path via the at least one traffic portion. However, the at least one reallocated traffic portion appears as though it is still continuously available to the first digital communication path.

A technique for integrating services digital network (ISDN) and code division multiple access (CDMA) or other digital wireless communication protocols by a technique that strips off lower protocol layers, such as layers one and two of the ISDN protocol and sending only layer three and above messages over a more efficient wireless protocol.

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.

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.

H04Q 7/20

455453000

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.
