    摘要: The specification and drawings present a new method, system, apparatus and software product for using a new modified dual symbol rate (MDSR) in an uplink direction in mobile communication systems. The communication between the mobile station and the network element may be performed within evolved GSM/EDGE radio access networks. The MDSR can be for example one and a half times a symbol rate of an uplink speech service, e.g., the current GSM/EDGE symbol rate (13/48 MHz) in the mobile communication system, thus the MDSR may be substantially 13/32 MHz or about 405 kHz. The uplink signal with the MDSR may be modulated, e.g., using a quadrature amplitude modulation (QAM), e.g., 16-QAM with 16 states and/or a quadrature phase-shift keying (QPSK, or π/4-QPSK) modulation.

    摘要: A method and corresponding equipment for use by a mobile station and/or a radio access network, for altering one or more characteristics of transmissions of the mobile station to a base transceiver station of the radio access network in respect to power and/or modulation and/or coding of the transmissions, based on monitoring broadcast transmissions from other base transceiver stations of the radio access network and determining an estimate of the likelihood of transmissions by the mobile station interfering with communication between the other base transceiver stations and the mobile stations in communication with those other base transceiver stations.

    摘要: The specification and drawings present a new method, system, apparatus and software product for a timeslot (TSL) reuse typically combined with a frequency reuse for a service based interference control in communication systems. TSL reuse method can be applied to a service with a wider spectrum or a higher symbol rate than for a normal channel bandwidth of a communication system to provide the way for controlling interference. The TSL reuse method can enable interference control for synchronized and unsynchronized networks in uplink (UL) or downlink (DL).

The method comprises the steps of determining (S1) a classifier (CL_C) in a current data block, calculating (S3) a mean (M) of classifiers (CL—1 to CL_N) of a predetermined number (N) of data blocks, calculating (S4) a standard deviation (σ) of the classifiers (CL—1 to CL_N), calculating (S5) a threshold for identifying bad frames on the basis of the mean (M) and the standard deviation (σ) of the classifiers (CL—1 to CL_N), and distinguishing (S6) whether the current data block is usable or not on the basis of a comparison of the threshold (TH) and the current classifier (CL_C). By the method and the device, changing conditions of a radio channel can be taken into account quickly.
