摘要： The present invention relates to space-time or space-frequency coding in cellular systems. The same data is transmitted from different antennas with different coverage areas, corresponding to different cells. The different data streams have different parts of the space-time block codes applied. A mobile terminal can combine the different parts of the space-time block codes in different received signals. This provides better performance than the known techniques for single frequency networks. The invention can also be applied to antennas with different coverage areas from the same site, and different beams formed with antenna arrays.

摘要： A method is disclosed for transmitting channel quality reports periodically from a secondary station to a primary station, wherein transmission of a control channel is carried out discontinuously with a predetermined periodic transmission phase, and wherein said method comprises the following steps. Scheduling the transmission of a transmission sequence of channel quality reports of at least a first type and a second type according to a predetermined pattern. Estimating the number of channel quality reports of the second type scheduled during the transmission phases of a predetermined time window. Amending the transmission sequence by replacing at least one channel quality report scheduled to be of the first type with a channel quality report of the second type if the number of second type channel quality reports scheduled during the transmission phases of the predetermined time window is below a predetermined threshold. Transmitting the amended sequence to the primary station.

摘要： In a radio communication system having a data channel for the transmission of data packets from a primary station to a secondary station, a plurality of downlink control channels are used to signal information relating to packet transmission. A problem with this scheme is that with a fixed control channel allocation system throughput (T) for a given offered load (O) can be significantly reduced in a worst case scenario (for example two secondary stations using the same control channel). One solution uses an indicator signal to inform a secondary station of the control channel it should receive, but this adds significant complexity to the system. The present invention provides a simpler scheme having similar benefits by shuffling the allocation of control channels to secondary stations, according to a defined sequence for each secondary station, thereby avoiding the worst case scenario.

摘要： The present invention relates to the signaling of channel quality information in a multi-beam transmission system, wherein a plurality of beams are simultaneously transmitted and a plurality of sets of channel quality information are transmitted for controlling independently the transmission rate on the different beams. Determined are beams with a different quality resulting in different effects of errors in the transmissions of the channel quality information for the beams. Said different effects are exploited for reducing a signaling overhead of the channel quality information for the beams.
