Abstract: In an Orthogonal Frequency Division Multiple Access communication system, the location of one- and two-dimensional bursts may be specified by specifying the starting location of the plurality of bursts. The length of a burst may then be determined by subtracting starting locations of successive bursts. In some embodiments, the number of bits needed to specifying the location of bursts may be reduced.

Abstract: When building a sub-frame for a wireless transmission that distributes the data over multiple simultaneous sub-channels, fragmenting the data to fit into the sub-frame may leave wasted space in the sub-frame because the minimum allowable size of the fragments leaves gaps. To increase overall throughput, these gaps may be wholly or partly filled in with another type of data that has smaller minimum size fragments. In some embodiments, the sub-frame may use orthogonal frequency division multiple access (OFDMA) protocols, and the two data types may be classified as automatic repeat request (ARQ)-enabled and non-ARQ-enabled data.

Abstract: A system and method of data transmission in a wireless communication network are disclosed. The method comprises detecting an error in an original transmission and in response thereto, determining that latency sensitive data in the original transmission would be stale when transmitting a copy of the original transmission. The method further comprises transmitting the copy of the original transmission when a retransmission value function at least equals a predetermined threshold and transmitting a new transmission when the retransmission value function is less than the predetermined threshold. The new transmission comprises a copy of the data from the original transmission that is not stale when transmitting the new transmission.

Abstract: A method constructing a downlink frame for a communication system using a plurality of coding schemes and a quality metric. The method includes: (a) In no particular order: (1) establishing stripes along a first axis; (2) establishing slots within each stripe; and (3) assigning each flow to a group according to its coding scheme. (b) Evaluating a wastage metric for each group. (c) Evaluating the quality metric for each group. (d) Employing the wastage metric and the quality metric to establish an efficiency metric for each group. (e) Allocating a first group having a predetermined efficiency metric to a first stripe. (f) Continuing allocating until all stripes are filled to desired capacity or until all flows are fully allocated. (g) Populating the frame according to the allocating.

Abstract: The present invention provides shared communication medium capability to the plethora of computer devices, like the PCCAs, that normally are able to communicate with other devices via dedicated point-to-point links, e.g., via the practically universal RS-232 ports. It allows the sharing of the communication medium in a dynamic fashion depending on the instantaneous traffic demands by the various communicating devices. It further allows the emulation of point-to-point links over the shared communications medium in such a way that applications running on a PCCA use the shared medium transparently. Thus, this invention enables applications designed to operate over a point-to-point connection to operate over the shared medium without any modifications of the applications or the point-to-point devices.
