20080254748 | Method For Dimensioning or Evaluating a Radio Network - A simple and reliable method for dimensioning CDMA based networks is achieved by a method for evaluating or dimensioning a radio network comprising the steps of—defining a radio network model comprising at least one radio base station and a plurality of mobile terminals, —for each mobile terminal in the model, defining a path gain value for a signal path between the mobile terminal and each of the radio base stations, said method being characterized by the steps of—for each mobile terminal, selecting at least one of said path gain values, —defining a data set comprising at least one parameter based on said selected at least one path gain value for each mobile terminal, and—performing dimensioning calculations on the data set. Especially if data sets are prestored the dimensioning calculations can be carried out in very short time. | 10-16-2008 |
20080298434 | Method and Arrangement for Frequency Hopping in Wireless Communication Systems with Carriers of Varying Bandwidth - The present invention relates to frequency hopping in wireless communication systems utilizing single-carriers with varying bandwidth. Frequency hopping is made possible by dividing the available bandwidth, associated to the available frequency spectrum, in a levelled structure, a bandwidth tree. By the use of a frequency hopping tree, which has the same structure as the bandwidth tree and wherein each leaf represent a hopping sequence, a frequency hopping scheme is determined. Orthogonality in-between the frequency hopping schemes for different users is ensured by letting a users hopping sequence value at a level n, be dependent on the hopping sequence value associated to the same branch structure on the adjacent level closer to the root of the tree, n−1, and an input sequence associated with the level n. | 12-04-2008 |

20100111030 | Frequency Hopping Scheme for OFDMA System - Available bandwidth is divided into multiple sub-channels, and respective sub-bands containing one or more of these sub-channels are allocated to one or more users. A first frequency allocation is determined, and mathematical operators are used to determine at least one further frequency allocation from the first frequency allocation. A frequency hopping sequence is then determined, including the first frequency allocation, and the or each further frequency allocation. A network node may perform the allocation method, and a user equipment may operate using the allocated bandwidth. | 05-06-2010 |
20110280146 | METHOD AND ARRANGEMENT FOR RECEIVE POWER ESTIMATION IN A MOBILE RADIO COMMUNICATIONS SYSTEM - The present invention relates to a method and apparatus for estimating a received signal power of a first transmission channel at a receiving node in a communications system wherein a received signal comprises information transmitted by a transmitting node over at least two transmission channels. The received signal power of a second of the at least two transmission channels is measured, and together with an estimate of the relationship between the transmission power of the second transmission channel and the transmission power of the first transmission channel; the measurement of the received signal power is used in estimating the received signal power of the first transmission channel. | 11-17-2011 |

20150312825 | METHODS, A NETWORK NODE AND A WIRELESS DEVICE FOR SUPPORTING HANDOVER IN A CELLULAR COMMUNICATIONS NETWORK - A way to support a handover of a wireless device from a serving cell being served by a serving base station to a candidate cell being served by a candidate base station is disclosed. A network node determines a respective value of one or more parameters for affecting a range for soft handover. The range of soft handover is applied by the wireless device to determine if the candidate cell is a subject for soft handover. At least one respective value of the one or more parameters is determined based on output power of a transmitter of the serving base station for serving the serving cell and/or of a transmitter of the candidate base station for serving the candidate cell. The network node provides a sending of the respective value of the one or more parameters to the wireless device. | 10-29-2015 |
