20110305154 | Transmitting a First and a Second Channel Quality Information Between Two Network Elements - It is described a method for transmitting channel quality information between a second network element and a first network element. The method includes (a) dividing a range of possible radio channel qualities between the two network elements into a fixed number of quality classes, (b) measuring the quality of a radio channel between the two network elements, (c) selecting one quality class out of the fixed number of quality classes based on the measured quality of the radio channel, (d) transmitting from the second network element to the first network element a first channel quality information being indicative for the selected quality class, and (e) transmitting from the second network element to the first network element a second channel quality information being indicative for the measured quality within the limits of the selected quality class. It is further described the first and the second network element, which in conjugation with each other are adapted to carry out the described method. | 12-15-2011 |
20120113897 | Method and Device for Data Processing in a Communication Network - A method and a device for data processing in a communication network are provided, wherein a mobile terminal receives several input signals from at least one base station; and wherein the mobile terminal processes said several input signals into a feedback information that is conveyed to at least one base station. | 05-10-2012 |
20120155366 | Controlling Scheduling Decisions in a Distributed Cooperation System - Feedback information is received from user equipments served by jointly processed data streams of a coordinated multipoint transmission at each base station of base stations serving the jointly processed data streams, and scheduling data is decided for the user equipments based on the feedback information and scheduling rules. The scheduling rules may be determined at least in part by one of the base stations and scheduling decisions by the base stations may be synchronized. Scheduling decisions may be transferred via a backhaul link and/or over the air, which may include scheduling decisions for future transmission time intervals. | 06-21-2012 |
20120207092 | Channel-Adaptive Transmission in a Distributed Coordinated Multi-Point Transmission System - A user equipment obtains channel state information for base stations serving the user equipment according to a coordinated multi-point transmission, arranges the channel state information in a predetermined order, and transmits the channel state information in the predetermined order. At least one base station of the base stations receives the channel state information, arranges the channel state information in the predetermined order into a datagram, and transmits the datagram to at least one other base station of the base stations. | 08-16-2012 |
20120250557 | Resolving Channel State Information Outdating - It is described a method of operating a base station and a base station which uses a communication channel depending on channel state related information and time information e.g. a prediction time. In this way, problems due to outdating of the channel state related information may be overcome and a feedback overhead may be reduced. According to other embodiments, other parameters like a used prediction method, a prediction horizon, etc. are used to provide a better scenario adaption. Other embodiments relate to combined long term prediction and short term prediction and respective timing settings. Other embodiments relate to a method of operating a user equipment and a user equipment which is adapted for communicating the required time information between the base station and the user equipment. | 10-04-2012 |
