摘要： 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.

摘要： In a cellular radio communication system for several user stations, each radio cell in the radio communication system includes a base station by which the information is transmitted to user stations using broadcast and/or point to multipoint connections. At least two radio cells in the cellular radio communication system are each divided into n radio sectors with n≧2 and the information is transmitted in each of the n radio sectors of a radio cell with a temporal displacement to improve the interference situation. The information is advantageously transmitted in n radio sectors without any temporal overlap. Radio sectors can particularly advantageously be collected in a group, alternately including the lowest coupling factors with regard to radio transmission and transmitting the information for each group at a different time.

摘要： The present invention relates to a method and system for data transmission in a data network. According to the method, a data packet is sent from a sender to a receiver. If a data packet is incorrectly received on the receiver, a repeat request is sent from the receiver to the sender. Upon receiving the repeat request on the sender, the data packet is resent from the sender to the receiver. After having received on the sender a predetermined number of repeat requests requesting the resending of the same data packet, a predetermined quantity of copies of the data packet is sent from the sender to the receiver, wherein the predetermined quantity includes at least two copies, or a predetermined quantity of additional information packets is sent from the sender to the receiver.

摘要： A method of selecting suitable frequency bands for data transmission between a network node and a user equipment within a mobile communications network. A method selects suitable frequency bands for data transmission between a network node and user equipment within a mobile communications network. A scheduler on the network node side selects data transmission mode depending on the user equipment capability of receiving data from at least two frequency bands simultaneously. The scheduler preferably selects the data transmission mode in the following way: simultaneous data transmission over at least two frequency with or without splitting traffic data or data transmission over only one available frequency band. For data transmission, a radio frame structure (Big MAC element) is dynamically established in the so-called medium access control layer, shortened so-called MAC-layer, by using concurrent radio resources from other frequency bands or other radio access technologies.
