    Abstract: A method and system for reducing delay in wireless communications by use of a burst based access and assignment system. The method for setting up a communication channel uses short burst(s) (essentially a slot of a time frame). Time is saved by keeping the uplink and downlink channels flexible and independent of each other. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. The result is less delay to the mobile user and greater usage density for the wireless service provider.

    Abstract: Information is coded and segmented into a plurality of sub-packets. Each sub-packet contains identification information and a one-bit information status flag indicating whether the information is 'new' information or 'continue' information. The information to be transmitted is then applied to a scheduling algorithm that determines when the information is to be transmitted, how much information is to be transmitted and how many attempts at a successful transmission of the information is allowed. In this manner, the transmission of information can be performed in an asynchronous manner.

    Abstract: In a wireless data network, such as a General Packet Radio Service (GPRS) network, a transmitter uses one of k coding/modulation schemes for transmitting data. The transmitter initially selects a coding/modulation scheme, C , as a function of carrier-to-interference ratio ( C/I ) measurements. The transmitter then calculates the number of blocks, B , required to transmit a number of data packets, D , using the coding/modulation scheme C . In addition, the transmitter calculates the number of blocks required to transmit the number of data packets, D , for each coding/modulation scheme that is stronger than the selected coding/modulation scheme C . The transmitter finally selects that coding/modulation scheme that results in transmitting the number of data packets D in B blocks using the strongest coding/modulation scheme. As a result, each block is transmitted using the strongest coding/modulation scheme available.
