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 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 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 technique for providing high speed data service over standard wireless connections via an unique integration of protocols and existing cellular signaling, such as is available with Code Division Multiple Access (CDMA) type systems through more efficient allocation of access to CDMA channels. For example, when more users exist than channels, the invention determines a set of probabilities for which users will require channel access at which times, and dynamically assigns channel resources accordingly. Channel resources are allocated according to a buffer monitoring scheme provided on forward and reverse links between a base station and multiple subscriber units. Each buffer is monitored over time for threshold levels of data to be transmitted in that buffer. For each buffer, a probability is calculated that indicates how often the specific buffer will need to transmit data and how much data will be transmitted.

Abstract: A scheme for assigning priority levels to users based upon a history of their request for access to the resources. If a user has, over a historical period of time, made fewer demands than a stated amount, that user is given a higher priority than a user who has made greater use of the resources than their stated amount. Thus, users making the heaviest demand on the available resources are allocated fewer resources despite their demand, whereas users that make less demands for the resources are granted more of the resources they request. An additional feature of an access allocation scheme according to the present invention is to reserve at least some resources for the users at the lowest priority levels. Thus, even users being assigned to a lowest priority queue will be granted at least some access once in a while. A third feature in connection with the present invention is to use the time of continuous transfer as a threshold to drop a presently assigned priority.

Abstract: 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 10−6 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.

Abstract: 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.
