摘要： A method is provided in a base station for handling a request from a first user equipment for accessing a service in a radio communications network. The method comprises the steps of receiving a first time interval of an incoming signal comprises a first signal sent from the first user equipment and a second signal sent from the second user equipment, interpreting the first signal as being a possible service access request message preamble, and sending an acknowledgement, that the preamble is detected, to the first user equipment. The method comprises the further steps of delaying the first time interval of the incoming signal, identifying the second signal in the first time interval of the incoming signal during the delay, washing the identified second signal away from the first time interval of the incoming signal during the delay, and deciding whether the possible preamble is a real preamble or not, by analyzing the washed incoming signal.

摘要： To reduce and/or guarantee the round-trip delay of interactive processes, cooperative scheduling in forward and backward direction is proposed. In practice, a basic idea is to estimate the delay of packets of different users during network-based scheduling of packets in forward direction. During scheduling of packets in backward direction, packets of those users having larger delay in forward direction are given higher priority based on the estimated delay. In this way the total round-trip delay can be reduced and/or even guaranteed. This means that more users will be satisfied and experience faster connections to services.

摘要： A display controller is configured for creating a translucency effect for a target image area of a source image containing image data expressed in a first color model. The display controller has a first color model converter adapted for color model transformation of the image data from the first color model to a second color model based upon a first predefined set of transformation coefficients, as well as a second color model converter adapted for color model transformation of the image data from the first color model to the second color model based upon a second predefined set of transformation coefficients. The display controller is controllable to produce a destination image by selecting transformed image data from the second color model converter for the target image area and by selecting transformed image data from the first color model converter for other image area(s) of the source image than the target image area.

摘要： An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.

摘要： Method and arrangements for scheduling transmission resources in a first node in a cell comprised within a wireless communication network. The first node is arranged to communicate over a communication channel with at least one user equipment within the cell. The communication is made by using a frame comprising uplink resources and downlink resources with a switching point between the downlink resources and the uplink resources. The method comprises the step of obtaining a parameter referring to the expected transmission quality of the communication and/or the expected coherence properties of the communication channel. The method also comprises scheduling a transmission on an uplink or downlink resource. The resource is located on a time distance from the switching point. The time distance is based on the obtained parameter.

摘要： The invention relates to methods and arrangements for an event triggered DRX cycle adjustment. A user equipment located in a serving cell of a mobile communications network monitors downlink communication at predetermined time intervals when operating in discontinuous reception mode. The user equipment also performs communication parameter measurements regarding at least one of the serving cell and one or more neighbor cells. After the occurrence of a first event, the user equipment sends at least one of measurement data and a first event report to the network. The sending is triggered by the occurrence of the first event. The monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein the second event is defined to indicate a higher probability of receiving a handover command than the first event.
