The invention relates to a base station, comprising: a transceiver for multi-carrier radio transmission within a radio frequency band, the transceiver being adapted to receive service quality requests of a plurality of users requesting service from the base station; and a radio resource controller being adapted to allocate subcarriers of the multi-carrier radio transmission to the users and configure the subcarriers in the radio frequency band according to the service quality requests of the users.

Base station and method for controlling radio resources allocation

A method is described, which includes controlling a coordinated transmission between network control elements and terminals on resource elements, detecting whether a resource element includes a specific element, and selecting a resource element for the coordinated transmission, when it is detected that the resource element does not include a specific element. The application also describes some further aspects to improve a coordinated transmission such as a coordinated multipoint transmission is improved.

A base station applies precoding to the data based on a set of predefined codebooks. A first tracking mode with a first codebook from the set of predefined codebooks is used for the precoding, and at least a second tracking mode with at least a second codebook from the set of predefined codebooks is used for the precoding. The base station switches between the first tracking mode and the second tracking mode depending on at least one condition of the channel.

Method and device for data processing in a communication network

In a method for wireless communication, a receiver receives a first signal at a first radio frequency and determines the reception level of the first signal. The receiver receives data during a reception level of the first signal at the first radio frequency. The receiver decides, based on the determined reception level, whether at least one measurement is to be taken on a second signal transmitted at a second radio frequency. A radio station carries out the method.

Intra-frequency and inter-frequency measurements in a radio communication system

A method of transmitting data in a communication network is provided, wherein the method includes receiving an error message indicating that a data packet precoded by using a first matrix and transmitted a first time by using a cooperative transmission scheme is not decoded correctly, preparing an recoded data packet by precoding the data packet using a second matrix which is different to the first matrix, and retransmitting the recoded data packet.

Communication network element and method transmitting data

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. 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 is disclosed.
