摘要： A multi-carrier transmitting apparatus and method is described, wherein a plurality of carrier signals are combined in the digital domain and supplied to a D/A converting means (3) for converting the combined digital carrier signals into an analog signal to be transmitted. The frequency characteristic of the D/A converting means (3) is compensated by scaling means (51 to 54) for pre-scaling individual ones of said plurality of carrier signals before being combined and supplied to D/A converting means (3). The pre-scaling may be performed by multiplying digital data, representing the carrier signals, by corresponding frequency-dependent digital scaling words. Thereby, the need for signal processing intensive digital filters or non-ideal analog filters can be prevented. In case a digital power control is provided, the scaling word can be combined with a power control word.

摘要： The invention relates to a wireless local loop system comprising base stations and an access network node which connects the cordless terminal equipments (T) to the exchange of the fixed network. The air interface between the cordless terminal equipment and the base station is mainly in accordance with the GSM mobile system. In addition to the base station, the terminal equipment (T) also measures the field strength and quality of the radio channel. There are at least two measurement periods during a multiframe of a traffic channel (TCH), and the terminal equipment transmits the measurement results of the first measurement period on a single burst in a time slot of a slow associated control channel (SACCH) and the measurement results of the second measurement period in a single burst in a time slot of an IDLE FRAME. There are at least two transmissions of control information during the multiframe, and the base station transmits the first control information in a single burst in a time slot of the SACCH and the second control information in a single burst in a time slot of the IDLE frame. In this manner the measurement period can be made shorter than the frequency of the Rayleigh fading.

摘要： The present invention proposes a method of channel allocation for a mobile terminal (MS) moving in a cellular communication network (NW), said method comprising the steps of: detecting (S21) the speed of said mobile terminal (MS) moving in said network, and dependent on said detected speed (S23, S25), allocating (S24, S26, S27) a channel of a specific type to said mobile terminal (MS). Accordingly, with the present invention implemented, delays in neighbor cell SCH decoding and signal level measurement are significantly reduced and may thus no longer result in incomplete data for inter-cell handover decision or even unsuccessfull handovers. Hence, communication network performance in particular in connection with handovers in a cellular network layout is improved. The present invention also concerns an accordingly adapted device for channel allocation.

摘要： For improving data transmission over the radio path between a mobile station and a base station in a mobile telecommunications system, a divider splits a data signal whose speed is higher than the maximum data transfer rate in one frame, into at least two signals of lower speed before transmission over the radio path. The mobile station is allocated at least two traffic channels for the high-speed data transmission so that each of the signals of lower speed is transmitted over the radio path in its respective traffic channel. A combiner combines the signals of lower speed received over the radio path, to reconstitute the original signal at the receiving end.

摘要： A method of implementing dynamic channel allocation in a cellular radio system. The cellular radio system includes, in each cell, at least one base station communicating with subscriber terminals within its area. The system includes, in one cell, at least two subeeils, which include an anrenna unit and in which all available frequencies are dynamically used. All antenna units listen to control channels that subscriber terminals use for connection set-up and a base station measures the power level of the control channels through the antenna units, on the basis of which an antenna unit providing the strongest sigxzal is selected for conricction set-up. The base station measures through the antenna units the interference level of all available traffic channels, on the basis of which that traffic channel in an antenna unit selected for connection set-up which has the least interference is selected for communication. The base station measures through the antenna units the power level of the signals of subscriber terminals having a uaffic connection.
