  • Publication number: 20160021622
    Abstract: A communication device receives data transmissions from a data transmitter. The communication device monitors at least one quality indicator indicative of a quality of service of the data transmissions and/or of a link quality. The monitoring is performed at an application layer of the communication device. An application executed on the application layer of the communication device generates at least one power control message as a function of the monitored at least one quality indicator and transmits the at least one power control message to the data transmitter.

  • Publication number: 20150215019
    Abstract: A mobile communications terminal with plural antennas for uplink communications with a network base station in a cell, uses an adaptive antenna selection algorithm to select antennas. A method of operating a mobile communications terminal. The cell operator or base station provides parameters and/or settings to the terminal to determine algorithm behavior in selecting antennas, for example, according to operative characteristics of signals in uplink communications in the network, operation of the terminal, and/or network conditions. A communications method includes sending from a base station one or more parameters and/or settings for a terminal to select which of plural antennas of the terminal to use transmitting signals to the base station. A base station transmits to terminals one or more such parameters and/or settings for use in the adaptive antenna selection algorithm to select antennas for transmitting signals to the base station.

  • Patent number: 9008026
    Abstract: A device and a method within a communications system where at least some part of the transmission is executed by means of radio waves, and where symbols are transmitted by means of Orthogonal Frequency Divisional Multiplexing, so called OFDM-technology, between a transmitting unit and a receiving unit, at which the symbol transmission is executed over a transmission channel in blocks of binary digits with a guard interval GI between said blocks, where transmitting unit is equipped with means to control the length of the guard interval (GI) with regard to the physical conditions for/of the transmission channel, so that the guard interval can be reduced without the disturbance susceptibility being increased, but instead increasing the capacity/throughput of the transmission channel by the time that is set free/made available being used to transmit information. One embodiment of the invention includes a guard interval adjustment unit connected to other OFDM-equipment in transmitting and/or receiving unit.

  • Patent number: 8184596
    Abstract: A method for setting up a radio traffic channel in a 3G-network shared between at least two operators. The network's traffic channel resources are divided into operator specific parts, the parts not sharing any common traffic channels. User equipment is allocated channel resources in accordance with it's associated operator, according to a coarse level allocation control, which may be overridden in case no idle traffic channels are available. The allocated traffic channel is preferably associated with the user equipment operator and is furthermore idle in as a large area as possible and/or exhibits an optimum QoS, thereby maximizing network capacity and throughput by minimizing the probability of inter-frequency handover signalling and compressed mode operations. A radio network controller includes installed software, which carries out the traffic channel allocation and control.
