| 20080198910 | Noise Estimation In Wireless Communication Systems - The invention relates to background noise estimation in wireless communication systems with power control. The total received interference is measured at a receiving unit. Thereafter, a predetermined noise signal is injected at the receiving unit and the total received interference is measured again, preferably when the power control of the system has responded to the noise injection. The background noise is calculated based on the injected predetermined noise signal and the interference measurements before and after the noise injection. | 08-21-2008 |
| 20080310322 | Methods and Arrangements for Estimating Uplink Coverage in Wireless Communication Networks with Dynamic Cell Coverage - The present invention relates to methods and arrangements in cellular communication networks exhibiting dynamic cell coverage, in particular, to estimate the uplink coverage in a network in operation. According to the method of the present invention a received rate is determined from at least one mobile terminal being in a communication session, by measuring the number of received transport blocks during a predetermined time interval. The received rate is compared with a predetermined expected rate, and if the received rate is below the expected rate poor coverage is identified. Since the coverage is potentially load dependent an estimate of the uplink coverage has been obtained. | 12-18-2008 |

| 20090190485 | Method of Closed Loop Power Control Adjusted by Self-Interference - A method and apparatus for controlling the transmit power of a mobile device in a mobile communication network takes the level of self-interference into account to perform inner-loop power control. For normal inner-loop power control, a signal quality estimate is compared to a signal quality target and power control commands are generated based on the comparison. When self-interference is the dominant impairment in the received signal, a “fast break” is introduced to change inner-loop power control command generation. | 07-30-2009 |
| 20100135169 | Channel Quality Reporting Method and Arrangement in a Telecommunication System - When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits. | 06-03-2010 |

| 20100232526 | METHOD OF SELECTING A MODULATION AND CODING SCHEME BASED ON ADJUSTED CHANNEL QUALITY VALUES - In a method for selecting modulation and coding scheme for data transmitted from a transmitter to a receiver, the transmitter determines an estimated channel quality value. The transmitter then adjusts the estimated channel quality value in relation to a distribution of estimated channel quality values, and selects modulation and coding scheme based on the adjusted channel quality value. The invention also extends to a transmitter and a computer program product configured to select modulation and coding scheme accordingly. | 09-16-2010 |
| 20100278133 | Method And Arrangements For Facilitating Allocation Of Radio Resources - The present invention relates to methods and arrangements for facilitating the allocation of radio resources in a communication network, comprising a communication network node communicating with a user equipment by means of data stream transmissions over a radio interface on radio channels. What power allocation said communication network node will use for next to said user equipment incoming data transmission is predicted. Based on the power allocation prediction information on if a single data stream transmission or if a multi data stream transmission is selected for said communication is transmitted from the user equipment to the communication network node in a channel quality message. Whereby said communication network node is arranged to allocate available radio resources based on said channel quality message. | 11-04-2010 |
| 20110077030 | LTE FINGERPRINTING POSITIONING REFERENCES FOR OTHER CELLULAR SYSTEMS - High precision UE position estimates derived by OTDOA positioning in an LTE network are provided to other networks (e.g., WCDMA and/or GSM), along with inter-RAT measurements performed on the other networks, to support fingerprinted positioning databases in the other networks. Signaling is provided enabling LTE UE position estimates to be used as reference points in the fingerprinting database in each of GSM control plane AECID positioning, GSM user plane AECID positioning, WCDMA control plane AECID positioning, and WCDMA user plane AECID positioning. In support thereof, inter-RAT measurement supporting the population of databases in WCDMA and GSM, using fingerprints and reference measurements in LTE; the use of OTDOA positioning to generate the LTE UE position estimates, and the required signaling are disclosed. The AECID databases in WCDMA and GSM networks do not have own-network serving cells at the top hierarchical level, since the inter-RAT measurements are performed in LTE. | 03-31-2011 |
| 20110149914 | CHANNEL QUALITY HANDLING FOR PRECODER OVERRIDE - Technology is described that allows the transmitter to make different channel quality adjustments to reported channel quality information for use in allocating resources for subsequent transmissions depending on whether a precoder recommendation is used or overridden. When a reported precoder recommendation is overridden in favor of an alternate precoder, a different channel quality adjustment value associated with the alternate precoder is used, which results in improved transmission performance. | 06-23-2011 |
