| 20090310537 | WIRELESS COMMUNICATION SYSTEM AND METHOD FOR DETERMINING THE SIZE ALLOCATED TO A FIELD IN THE HEADER OF A PACKET BASED ON THE LENGTH OF THE PACKET PAYLOAD - The invention relates to a method of transmitting a data signal in a wireless communication system fro m a primary station to a secondary station, said data signal comprising a medium access control header (MAC-hs header) and a protocol data unit associated with said medium access control header, said medium access control header comprising a set of fields (TSN, SEG, LI, LCid), wherein said method comprises determining a size allocated to at least one field of the set on the basis of a length of the protocol data unit. For example, the size allocated to a segmentation indication field (SEG) determined for a first length of the protocol data unit is lower than the one determined for a second length of the protocol data unit, said second length being higher than said first length, said segmentation indication indicating in how many segments the protocol data unit is subdivided. | 12-17-2009 |
| 20090310693 | EFFICIENT CQI SIGNALING IN MULTI-BEAM MIMO SYSTEMS - 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. | 12-17-2009 |
| 20090323839 | EFFICIENT CQI SIGNALING IN MIMO SYSTEMS WITH VARIABLE NUMBERS OF BEAMS - The present invention relates to the signaling of channel quality information in a multi-beam transmission system, wherein a plurality of sets of channel quality information are transmitted for controlling the transmission rate on one of the beams, wherein each set of channel quality information is derived dependent on an assumed parameter of at least one other beam which could be transmitted, comprising selecting a parameter of the transmission of each of the sets of channel quality information dependent on the assumed parameter of the at least one other beam. | 12-31-2009 |
| 20100035565 | EFFICIENT CQI SIGNALING MIMO SYSTEMS WITH VARIABLE NUMBERS OF BEAMS - The present invention relates to a multi-beam transmission apparatus and system, and to a method for operating a multi-beam transmission system, wherein a first transmission resource information and a second transmission resource information are determined for respective first and second transmission beam, and wherein a first transmission parameter information and a second transmission parameter information are determined for the respective first and second transmission beams. The first and second transmission resource information and the first and second transmission parameter information are jointly encoded into a joint signal; and the joint signal is transmitted via the first and second transmission beams from a first station to a second station. | 02-11-2010 |

| 20080293439 | Associated Paging Indicator - A receiver for receiving wireless communication signals from a transmitter is arranged to operate in one of a plurality of states. The receiver is arranged to perform a state transition from the current state to another state among the plurality of states upon reception of a Paging Indicator Signal. The Paging Indicator Signal comprising an indication of the one of the plurality of states to which the state transition is to be performed. | 11-27-2008 |
| 20090190681 | SPACE-TIME/SPACE-FREQUENCY CODING FOR MULTI-SITE AND MULTI-BEAM TRANSMISSION - 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. | 07-30-2009 |
| 20090290495 | RADIO COMMUNICATION SYSTEM - 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. | 11-26-2009 |
| 20110128859 | METHOD FOR COMMUNICATING IN A NETWORK, A SECONDARY STATION AND SYSTEM THEREFOR - The present invention relates to a method of communicating in a network, comprising a secondary station transmitting to a primary station a data packet comprising a report, the secondary station monitoring before transmission of the packet whether said packet includes an indication of the order of transmission in a sequence of transmitted packets, and adding an indication of the order of transmission in a sequence of transmitted packets. | 06-02-2011 |
| 20110143765 | METHOD FOR COMMUNICATING IN A NETWORK, A SECONDARY STATION AND A SYSTEM THEREFOR - The present invention relates to a method for communicating in a network, comprising a) a secondary station preparing the transmission to a primary station of a message comprising at least a data field for containing data in an allocated resource, said resource comprising a plurality of resource blocks, and b) if the size of the allocated resource is bigger than required for the size of the message, the secondary station dividing the allocated resource in a first portion and a second portion, each portion comprising at least one resource block, c) the secondary station transmitting the message to the primary station in the first portion of the resource, d) the secondary station preventing from transmitting in the second portion of the resource. | 06-16-2011 |
