    摘要: A method of adapting resource allocation parameters to reach one or more quality targets with improved accuracy is proposed. New information measurements based on the so-called mutual information, preferably at block-level, are introduced. The MI-based information measurements of a previous transmission, the channel prediction of a subsequent transmission and one or more quality requirements, are used to determine the amount and type of resources, e.g. time, frequency and power resources, that are to be used for the subsequent transmission. The resource allocation can for example comprise power allocation and/or link adaptation and the invention enables an advantageous implementation with cooperative link-adaptation and power allocation. The proposed method is useful in connection with ARQ/HARQ retransmissions.

    摘要: Methods, systems, and arrangements enable balanced base station transmitter output power levels with respect to a receiving mobile station in a macro-diversity communication by adjusting a base station transmitter output power level responsive to power control command(s) sent by the mobile station and the (current) transmitter output power level of the base station. In a fixed adjustment step embodiment, power level convergence is enabled by adjusting the transmitter output power level of a given base station by a greater amount (e.g., than the nominal amount) when a power control command orders a power adjustment of the transmitter output power level towards a reference level and by adjusting the transmitter output power level by a lesser amount when a power control command orders a power adjustment of the is transmitter output power level away from the reference level. A continuous adjustment step embodiment is also disclosed.

    摘要: The invention relates to a method of performing handover in a mobile radio system. The mobile radio system performs quality measurements on signals transmitted (300) between a mobile terminal and predetermined radio base stations. Handover is performed (301, 302, 303) when some of the measured signal strengths exceeds the signal strength for the radio base station to which the mobile terminal for the moment is set up, added to a handover value. The handover value is dependent on measured signal strengths and neighboring cell relation values. The neighboring cell relation values depend on a probability for handover to be performed from one radio base station to another radio base station in the mobile radio system.

    摘要: A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function P based on a terminal identification (K)). The cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames. A communication module (600c) then communicates with the second mobile terminal (602), either by transmission or reception of the data, on the determined resource element (RE).

    摘要: Systems and methods of cell selection are based on measures of frequency selectivity, time selectivity, and/or antenna selectivity. For example, the delay spread and coherence bandwidth of a channel are two measures of frequency selectivity that can be taken into account in the cell selection process. In addition to or instead of either delay spread or coherence bandwidth, Doppler frequency shift or coherence time (which are two measures of time selectivity) and/or antenna correlation or mean signal strength per antenna (which are two measures of antenna selectivity), among other parameters, can be determined and taken into account.
