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: In a PRACH channel, colliding signals are resolved by use of a number of training-like symbols in the colliding data payloads. The signals are estimated by spatio temporal filters running a training-based or semi-blind algorithm, and a selection criterion is applied to the estimated signals, such as distance from the finite alphabet or the mean square error.

Abstract: According to the present invention there is provided a method of transmitting user data in a TDMA system in which the number of channels is increased by partitioning at least one time-slot in a TDMA frame into at least two sub-time-slots. Each sub time-slot may be allocated to a different user. User data may be transmitted in each time slot in a burst structure, user data being transmitted in each sub time-slot in a corresponding burst structure. User data may be transmitted in each time slot in a burst structure having n bits and wherein each time slot is partitioned into m sub time slots, user data being transmitted in each sub time-slot in a corresponding burst structure having n/m bits.

Abstract: A cellular radio communication system is disclosed for effecting handover of radio transmissions between a mobile station and one cell of a multicell network from said one cell to another cell of the network. The mobile station has a plurality of modes of operation in conjunction with the network. The plurality of modes includes a) a mobile station controlled autonomous cell reselection mode with no measurements being reported to the network, b) a mobile station controlled autonomous cell reselection mode with a measurement report being transmitted to the network, c) a network controlled cell reselection mode with a measurement report from the mobile station to the network, and d) a network controlled real time cell selection mode with a measurement report from the mobile station to the network.

Abstract: In the GPRS, a method of decoding uplink status having reduced interleaving depth in a RLC/MAC block is proposed; for RT-EGPRS users, all of the uplink flag bits are provided in the first burst of the four bursts; and for EGPRS users, nine bits of the uplink status flags are provided in the first burst of the RLC/MAC block and the remaining bits in the next three bursts. On receiving the first nine bits, a mobile performs an autocorrelation to identify the USF whether it belongs to the EGPRS or to the RT-EGPRS group.
