摘要： A method and circuitry for channel estimation in a cellular communication system is disclosed. Data is transmitted with variable data transmission rates as a plurality of data symbols over a sequence of time slots. Each time slot has at least a proportion containing data symbols, the proportion being dependent on the data transmission rate. An estimate of the transmission rate is determined and is used in channel estimation so that the channel estimation is based on the proportion of received data symbols.

摘要： In mobile communications systems of the CDMA type in particular detection of individual signals from the received common signal with known methods requires much processing capacity of the mobile communications system. The present invention concerns a method of reducing radio inter-ference in a mobile communications system including at least one base station (BS) and several mobile stations (MS). The mobile communications system uses several traffic channels for communications between the base station (BS) and the mobile stations (MS). The method according to the invention is characterized in that signals received at the same reception point are classified therein into at least two classes according to the interference tolerance of the signal or according to the interference caused by the signal to other signals and/or according to the complexity of decoding of the signal, a special way of functioning is defined for each class, whereby the total interference caused by received signals to one another is reduced by complying with these ways of functioning, and the individual signals of each class are processed at the point of reception in the way of functioning defined for the class in question.

摘要： An out-of-synchronization condition for a Universal Mobile Telecommunications System (UMTS) is defined for a situation in which it may be difficult to distinguish an out-of-synchronization condition in a downlink dedicated channel from interference on that channel. A request is sent on an uplink from a user equipment (UE) to a base station transceiver (BST) for increased power on a downlink channel experiencing a possible frames out-of-synchronization condition, which may instead be a possible interference condition, so as to attempt to eliminate the possible interference. After a first selected period of time without eliminating the possible interference problem, the uplink is terminated unless a broadcast downlink channel is determined to be experiencing interference below a selected level, in which case the UE is allowed to continue to send the request for increased power. Only after a second selected period of time without eliminating the possible interference problem is the uplink terminated.
