摘要： The present invention provides a method, base station and user equipment for transmitting data in a mobile communications system, wherein said data is transmitted on at least one channel between at least one base station with multiple antennas and at least one user equipment. The base station applies precoding to the data based on a set of predefined codebooks. A first tracking mode with a first codebook from said set of predefined codebooks is used for said precoding, and at least a second tracking mode with at least a second codebook from said set of predefined codebooks is used for said precoding. The base station switches between said first tracking mode and said second tracking mode depending on at least one condition of said channel.

摘要： 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.

摘要： A method for operating a radio communication system involves the use of OFDM and involves a first sending station modulating a first OFDM symbol onto a first carrier frequency and sending the first OFDM symbol to a first receiving station via a first transmission channel using an air interface. In line with the invention, the first sending station changes the first carrier frequency during a time used for sending the first OFDM symbol, the change in the first carrier frequency being made independently of a change in transmission characteristics of the first transmission channel over time. A fast frequency hopping system (FFH-OFDM) is disclosed.

摘要： 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.

摘要： A method for transmitting a signal is described, wherein the method has transforming a signal into a frequency domain to obtain a spectrum, forming a filtered spectrum according to a filter spectrum and occupying a set of subcarriers of a frequency domain representation of an Orthogonal Frequency Division Multiplex (OFDM) signal with the filtered spectrum. A temporary signal is obtained by transforming the frequency domain representation of the OFDM signal into a time domain. The temporary signal is subjected to a phase modulation.
