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.

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 radio communication system comprises a communication channel for the transmission of data packets from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination as an acknowledgement or a negative acknowledgement to the primary station for each of the plurality of packets.

摘要： A data signal is transmitted in a wireless communication system from a primary station to a secondary station. The data signal comprising a medium access control header (MAC-hs header) and a protocol data unit associated with the medium access control header. The medium access control header comprising a set at least one field (e.g. TSN, SEG, LI, FMT, LCid), wherein a size allocated to at least one field of the set is determined based on a length of the protocol data unit. For example, the size allocated to a segmentation indication field (SEG) determined for a protocol data unit of a first length is less than the size determined for a protocol data unit of a second length, the second length being higher than the first length, the segmentation indication depending on a number of segments that the protocol data unit is subdivided into.
