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: 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: A method of encoding at least two sets of data bits into a single encoded block is provided, wherein each set of data bits includes a primary set of bits to be encoded and a secondary set of bits to remain unencoded, wherein the encoding technique requires a set of code terminating bits to be added to the primary set of bits, the method comprising: combining the two sets of primary bits; and encoding the combined two sets of primary bits, whereby one set of code terminating bits is added to the combined two sets of primary bits. The two sets of data bits may each include a header portion and a payload portion, the payload portion comprising encoded speech. The encoding step may be a channel encoding step for encoding the at least two sets of data bits for transmission on a packet switched network. The data bits may be for transmission on an EDGE packet switched network, wherein the at least two sets of data bits are encoded into a single RLC/MAC block.

Abstract: There is disclosed a transmitter including a data encoder for encoding data packets in fixed length EDGE blocks. Each data packet includes a data header and a data payload. The transmitter additionally includes a speech encoder for encoding speech packets each including a speech header and a payload comprising a speech frame. The speech packets are encoded into blocks of equal length to the EDGE data blocks, the speech header being reduced relative to the data header.

Abstract: In a packet switched network is provided a method of encoding at least two packets into a single block, in which each packet is associated with a header portion, wherein the at least two packets are associated with the same user, the method comprising encoding the at least two packets and only one of the associated header portions. The at least two packets preferably have a payload portion containing speech frames and a speech header. Each speech frame may include a set of Class I bits and a set of Class II bits the method further comprising: encoding a first speech frame by encoding the set of Class I bits; encoding second speech frame by encoding the set of Class I bits; and encoding at least a portion of the header. The speech frames may be for transmission on the down-link of a wireless packet switched network, wherein each encoding step comprises encoding two different portions of the header using two different encoding techniques. The Class I bits and a portion of the header may be encoded using a convolution code. The remainder of the header may be encoded using a block code. The speech frames may be for transmission on the up-link of a wireless packet switched network, wherein the Class I bits and the common header are encoded using a convulition code. The single block may additionally includes a set of stealing bits. The single block may include a set of spare bits.
