20120208584 | Method and Arrangement in a Communication System - The present invention relates to the area of communication, and especially to a method and an arrangement for antenna calibration in a communication system comprising a baseband unit (BBU) and distributed radio remote units (RRUs). The present invention aims to limit antenna calibration duration in the antenna calibration chain. A cable delay based on the length of the cable connecting the BBU and the RRU is obtained. A delay compensation is calculated based upon the cable delay. Thereupon the antenna calibration chain utilized by the BBU and the RRU is adapted based upon the delay compensation. | 08-16-2012 |

20120258752 | BASE STATION SYNCHRONISATION - A method for determining data enabling a plurality of secondary base stations to time their transmissions to a mobile station within a timing range. The mobile station obtains time delays of transmissions from each of the secondary base stations in reaching the mobile station, and determines time delay differences between the time delays and a reference time delay associated with a primary base station. The mobile station transmits the time delay differences to the plurality of secondary base stations. Each secondary base station receives the difference between its own transmission time delay and the reference time delay, compares the difference with a time range, and corrects the timing of its transmissions if the difference is outside of the time range. | 10-11-2012 |
20130064277 | Method, Apparatus and System for Antenna Calibration - The present invention discloses a method, an apparatus and a system for calibrating antenna, wherein channel transfer functions are obtained for subcarriers on at least one antenna to be calibrated and on a reference antenna, and the obtained channel transfer function of a first subcarrier is filtered by multiplying a symmetry filter with channel transfer functions of said first carrier's neighboring subcarriers, and the filtered channel transfer function is normalized; and a signal carried by the first subcarrier on the antenna to be calibrated is multiplied with the ratio of the filtered and normalized channel transfer function of the first subcarrier on said reference antenna to the filtered and normalized channel transfer function of said first subcarrier to get compensated. This enables to perform joint compensation on a subcarrier basis and thus reduce computation complexity. | 03-14-2013 |
20140050164 | Token Based Radio Resource Management - The disclosure relates to a method of globally balancing the transmit power in a cellular radio system with tight reuse of frequencies, to a central controller node, and to an access point that in combination with conventional power control schemes balances the downlink transmission power on re-used frequencies in order to balance co-channel interference in a multi-cell environment. The power balancing scheme takes the instantaneous channel variation and co-channel interference into account and satisfies the throughput requirements of the different cells when allocating downlink power to the user equipments. Global power balancing dynamically assigns a token to or takes a token away from an individual reused radio channel based on quality of, or based on transmission power in the channel. The balancing of transmission power, along with the conventional power scheme, prevents a global increase or global decrease of interference in the multi-cellular system. | 02-20-2014 |
