Abstract: A computing device can determine a radio frequency (RF) bandwidth in which one or more frames are to be transmitted by the computing device. The RF bandwidth is within the operating transmission bandwidth of the computing device. A signal interference having an interference bandwidth can interfere with the transmission of the one or more frames. In response to detecting the signal interference, one or more frames can be transmitted within the operating transmission bandwidth and not within the interference bandwidth.

Abstract: A wireless communications device that transmits a multiplexed signal of a plurality of data sets of different sizes to a communications terminal includes an empty resource block detection section, which detects empty resource blocks of the data sets each of which does not use any of a predetermined number of resource blocks, from among the plurality of data sets whereto the predetermined number of resource blocks are allocated in the time direction and the frequency direction; and a data redistribution section that redistributes a part of data that is distributed in resource blocks, with respect to the data sets whereto resource including empty resource blocks are allocated, in the vicinity of pilot symbols that are disposed within the empty resource blocks. It is possible to effectively utilize the function of all the pilot symbols and improve error rate characteristics.

Abstract: A noise rise estimation method calculates (230) a noise rise measure suitable for stability control purposes, based at least on a useful signal power for the first user after interference whitening, a first user noise floor compensation factor, a code power to interference ratio measure for the first user, a noise floor measure and an estimated neighbour cell interference power. These factors are provided by measuring (210) received total wideband power and generating (212) a measure of an own cell power. An estimate of the noise floor measure is computed (214) and the neighbour cell interference power is estimated (216) based on these measurements and generated measures. An interference whitening is performed (220). The useful signal power for the first user after interference whitening is determined (222). The first user noise floor compensation factor is derived (224) based on combining weights for the first user used in for the first user is obtained (226).

Abstract: Provided are a multicarrier based communication method and device. A mobile station activates a first carrier, and activates a second carrier adjacent to the first carrier. Defined within the first carrier there is a first frame comprising a legacy UL (uplink) region and an AAI (Advanced Air Interface) UL region; defined within the second carrier there is a second frame comprising an AAI UL region in the first frame occupy frequencies that differ from each other; and guard subcarriers between the AAI UL region of the first frame and the AAI UL region of the second frame are not used for data transmission.

Abstract: The present invention relates to a method for transmitting channel state information regarding downlink transmission through an uplink may comprise the steps of: receiving a downlink signal through a downlink channel; generating a rank indicator (RI) for the downlink channel, a first precoding matrix indicator (PMI), and a second PMI, and generating channel quality information (CQI) on the basis of pre-coding information which is determined by a combination of the first and second PMIs; and transmitting the RI, first PMI, second PMI, and/or CQI through the uplink channel. The CQI may comprises a first type of CQI calculated on the basis of the number N of layers in which the downlink signal is received and/or a second type of CQI calculated on the basis of the assumption that the number of layers in which the downlink signal is transmitted is K (where K>N).
