Patent application number | Description | Published |
20090185601 | CHANNEL QUALIFICATION FOR AN ADAPTIVE FREQUENCY HOPPING METHOD BY MEANS OF BIT OR PACKET ERROR RATE MEASUREMENT AND SIMULTANEOUS FIELD STRENGTH MEASUREMENT - This disclosure relates frequency channel qualification in wire-free communications system. | 07-23-2009 |
20100040121 | METHOD AND APPARATUS FOR ADAPTIVE ACTIVATION OR DEACTIVATION OF THE COORDINATION OF THE RADIO ACTIVITIES OF TWO MOBILE-RADIO TRANSMITTING AND/OR RECEIVING DEVICES - The method is based on the capability for coordination of the radio activities of two mobile radio transmitting and/or receiving devices. In the case of the method, a value of at least one characteristic variable is first of all determined, which is characteristic of the requirement for coordination of the radio activity of one or both transmitting and/or receiving devices. The coordination of the radio activity of one or both transmitting and/or receiving devices is then activated or deactivated as a function of the value. | 02-18-2010 |
20130244665 | Dynamic RxDiv for Idle Mode in a User Equipment - A method of evaluating a reception quality of a receiver includes determining a reception quality of the receiver using a measurement from a single active antenna of the receiver if the receiver is in the idle mode. The method further includes activating receiver diversity by activating at least a second antenna of the receiver in the idle mode if the measurement from the single active antenna of the receiver is below a first predetermined reception quality threshold. A receiver includes receiver chains configured to interface with respective antennas, and a reception quality estimation unit configured to determine a reception quality of a single active receive chain when the receive is in an idle mode. The receiver further includes a diversity controller configured to selectively activate at least a second receive chain in the idle mode based on the determined reception quality from the reception quality estimation unit. | 09-19-2013 |
20130337848 | MOBILE COMMUNICATION APPARATUSES, METHOD FOR PERFORMING SIGNAL RECEPTION QUALITY MEASUREMENTS AND METHOD FOR ASCERTAINING A MOVEMENT BY A MOBILE COMMUNICATION APPARATUS - A mobile communication apparatus is provided which has a receiver, an ascertainment device which is set up to ascertain whether the movement of the mobile communication apparatus is below a prescribed limit and a control device which is set up to prompt the receiver to perform a signal reception quality measurement on the basis of whether the movement of the mobile communication apparatus is below the prescribed limit. | 12-19-2013 |
20140162567 | RADIO COMMUNICATION DEVICES AND METHODS FOR CONTROLLING A RADIO COMMUNICATION DEVICE - A radio communication device may be provided. The radio communication device may include: a measurement circuit configured to measure a reception quality of a signal from another radio communication device; a retention time determiner configured to determine a retention time based on the measured reception quality; and a memory configured to store information related to the other radio communication device for a period of time, the period of time based on the determined retention time. | 06-12-2014 |
20140274068 | MOBILE TERMINAL AND METHOD FOR DETERMINING A RECEIVE WINDOW - A mobile terminal is described comprising a transceiver configured to establish, for each of a plurality of radio cells, a radio link to a base station operating the radio cell; a determiner configured to determine, for each radio cell, a timing of a downlink signal transmitted from the base station operating the radio cell to the mobile terminal and configured to determine, based on the timings, a timing for a receive window in which the transceiver is to buffer signal samples received via the radio cells and a controller configured to control the transceiver to buffer signal samples received via the radio cells during the receive window. | 09-18-2014 |
20150381321 | COMMUNICATION DEVICE AND METHOD FOR TRANSMITTING DATA IN ACCORDANCE WITH A RETRANSMISSION PROTOCOL - A communication device is described comprising a transmitter configured to transmit data according to a retransmission protocol, a determiner configured to determine whether, for a transmission time scheduled according to the retransmission protocol, there was a transmission gap within a predetermined time interval before the transmission time or to determine whether there will be a transmission gap within a predetermined time interval after the transmission time and a controller configured to control the transmitter to perform an initial transmission of data or a retransmission of data according to the retransmission protocol at the transmission time based on the result of the determination. | 12-31-2015 |
