摘要:
The present invention relates to a method for communicating between a primary station and at least one secondary station, comprising the steps of (a) at the primary station, requesting the secondary station to transmit channel quality information representative of the channel quality and, (b) at the secondary station, responsive to the request of step (a), transmitting to the primary station the channel quality information, wherein step (b) comprises sub-step (b1) wherein the secondary station further transmits with the channel quality information an indication of a secondary station buffer status.

The present invention relates to method for communicating between a primary station and a secondary station comprising (a) at the secondary station, upon arrival of a data packet to be transmitted to the primary station, buffering said data packet in a buffer, and transmitting to the primary station a request for an uplink transmission resource if a request condition is satisfied, said request condition being based on at least one previous grant of uplink transmission resource, (b) at the primary station, granting to the secondary station an uplink transmission resource to be used.

The present invention relates to a method for communicating in a network comprising a primary station and at least one secondary station, said secondary station comprising a buffer containing data packets to be transmitted to the primary station, the method comprising the step of the secondary station transmitting an indication of the buffer status to the primary station, said indication comprising information about history of said buffer.

The present invention relates to a method of exchanging data between a first station and a second station, said data being exchanged in packets. Said method comprises the steps of: receiving a packet from the second station; decoding said packet; —determining whether to transmit to the second station a resource allocation message on a signalling channel; if a said resource allocation message is transmitted, further transmitting to the second station a first indicator signal on an indicator channel; if both the decoding has not been successful and the said resource allocation message is not transmitted, transmitting to the second station a second indicator signal on the indicator channel.

The present invention relates to a method for communicating between a primary station and at least one secondary station, comprising configuring each secondary station to search at least one of a plurality of search spaces having a first structure, said first structure consisting of at least a first number of resource sets having a first size, where at least one resource set might be used to transmit a message to the considered secondary station, changing the search space structure to a second structure different from the first structure in response to a signalling message.
摘要:
First and second data is transmitted simultaneously by modulating a first set of signal constellation points, corresponding to the first data, with second data thereby creating a second set of constellation points. The second set of constellation points comprises two subsets corresponding to two values of the first data. The constellation points are selected such that the minimum distance between the first and second subsets is not less than the minimum distance between the constellation points of the first set of constellation points.
摘要:
A method of operating a packet data multicast communication system which comprises a network or NodeB (BS) and a plurality of mobile stations (MS1, MS2, MS3). The network and the mobile stations have transceiving equipment (14, 34) for the transmission of data packets on a downlink between the network and mobile stations, and feedback signalling (ACK/NACK) on an uplink. The mobile stations have means for receiving a data packet transmitted by the first station, means (46) for measuring the quality of reception, means (30, 48) for determining into which one of at least three predetermined quality ranges the measured quality falls. Each of the at least three predetermined quality ranges represents a respective transmitter behaviour of the first station and the transmitter behaviour corresponding to at least two non-contiguous ones of the quality ranges is identical.
