20090086682 | Downlink Out of Sync Detection in Continuous Packet Connectivity - Out-of-sync and in-sync detections and downlink power control by UTRAN user equipment are improved in Continuous Packet Connectivity mode featuring discontinuous UL DPCCH transmission by requiring all F-DPCH transmissions from a base station to the user equipment to be valid during a UL DTX gated period. Additionally, the user equipment receives and considers all F-DPCH transmissions during the UL DTX gated period, for power control, out-of-sync and in-sync detections. If the user equipment detects an out-of-sync condition, it may immediately transmit a scheduling request to notify the network, temporarily or permanently annulling the discontinuous UL DPCCH transmission. | 04-02-2009 |
20090149170 | APPARATUS AND METHOD FOR MEASUREMENT REPORTING IN A CELLULAR TELECOMMUNICATIONS SYSTEM - The signalling overhead in cellular communication systems such as OFDMA is reduced by calculating a report value as a function of each measurement value that is to be reported from a user terminal to the network. The report value is preferably based on a maximum value for the parameter measured, and can be represented by fewer bits than the measurement value. The overhead may be further reduced by selecting only the best measurement values for reporting from the user terminal to the network. | 06-11-2009 |

A limited CQI reporting is obtained by triggering the reporting according to one or more predefined rules, which to at least some extent depend on CQI specific information provided to the User Equipment from the network node. A User Equipment and a network node adapted to operate in accordance with the suggested method are also provided. | 06-25-2009 |
20090197606 | HIGH-SPEED SERVING CELL CHANGE - A device receives a measurement report generated by user equipment, and determines whether a serving cell for the user equipment should change from a source cell to a target cell based on the measurement report. The device also configures the source cell and the target cell for the serving cell change when it is determined that the serving cell for the user equipment should change, and transmits, via the target cell, a serving cell change message to the user equipment using a common network temporary identifier. The device further receives, from the user equipment, an acknowledgment of the serving cell change. | 08-06-2009 |

20090268696 | Method And Arrangement In A Mobile Telecommunication Network - The present invention is based on the idea to allocate HS-DSCH power at TTI based on the HS-SCCH allocation of TTI and an estimation of the HS-SCCH allocation of TTI+1. The estimation of the HS-SCCH allocation of TTI+1 is based on estimation of which users that will be scheduled at the time denoted TTI+1. i.e., the users that have a high probability to be selected for transmission by the scheduler at the time denoted TTI+1 are determined. That is performed by calculating for each user the probability that the user will be selected for transmission by the scheduler The users that have a high probability to be scheduled at the time TTI+1 are included in a candidate set according to the | 10-29-2009 |
20100020704 | Method, Apparatus And Computer Readable Medium For Obtaining Efficient Downlink Power Transmission - The invention relates to a method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a communication network entity transmitting data on a downlink channel over a radio interface to one or more user equipments, each of which is transmitting data on an uplink channel to said communication network entity over said radio interface. The communication network entity receives transmit power control (TPC) commands on said uplink channel and, further, monitors a channel quality indicator (CQI) on said uplink channel from said user equipment in order to obtain channel quality indicator measurements. If there is a channel quality indicator available, the communication network entity calculates a required downlink power. Otherwise, the communication network entity decodes said received transmit power control commands. Thereafter said transmission power is adjusted either based on the calculated downlink power or based on the decoded transmit power control commands in order to obtain efficient radio resource utilization. | 01-28-2010 |
