Abstract: A time division multiple access cellular radio telecommunications network is disclosed, in which physical channels may be reused in the same cell. Reused channels on the up link are differentiated by a time shift between them. Same cell reuse (SCR) can thus be implemented in a TDMA (GSM) system without assigning different signatures to SDMA users sharing the same physical channel.

Abstract: A method and apparatus for estimating channel impulse response and data in a signal transmitted over a channel in a communication system. The channel impulse response is estimated uses correlative channel sounding, and then, using the estimated channel impulse response, the data in the signal is estimated. The output is then fed back to the channel impulse response estimator and the channel impulse estimation is repeated. The data estimation and channel impulse response estimation may be iterated a number of times.

Abstract: A method of scheduling data packets and packet fragments for transmission from a first terminal to a second terminal over a channel shared with other terminals comprises scheduling at a packet data throughput rate that is determined by averaging the lengths of the packets and packet fragments for transmission then dividing the maximum supportable data rate by the average packet/packet fragment length determined.

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.
