Abstract: A mobile telephone 12 acts as a radio communications gateway between a 3G network 10 and a Bluetooth® network 11. A video conference call in the 3G network 10 is relayed over the Bluetooth® network 11 to and from a Bluetooth® enabled laptop Personal Computer (PC) 13, which therefore acts as a radio communications terminal. A Channel Quality Indicator (CQI) received by the mobile terminal 12 with the video conference content over the 3G network 10 is transmitted by the mobile telephone 12 to the laptop PC 13 over the Bluetooth® network 13 as a Pseudo-CQI (P-CQI). In this example, the P-CQI is sent in a FLOW control field of a header 40 of a Synchronous Connection Oriented (SCO) or extended SCO (eSCO) data packet of the Bluetooth® network 11. A video conference driver application running on the laptop PC 13 is then able to alter the video conference call properties according to the value of the P-CQI, thus responding to call quality conditions in the 3G network 10.

Abstract: A method for transmitting data from a primary station to a secondary station, includes the primary station signaling to the secondary station that a data message is to be received, and at the primary station transmitting the data message. The time of transmission of the data message relative to the time of the signaling depends on a state of the secondary station.

Abstract: When a radio station terminates a first service on a first radio frequency channel and selects a second radio frequency channel for engaging in a second service, a time delay is inserted after the termination of the first service and before selecting the second radio frequency channel or before engaging in the second service. The time delay is dependent on the state of the radio station and/or a characteristic of the second service.

Abstract: The present invention relates to a method for communicating data in a telecommunication network comprising at least one primary station, and a plurality of secondary stations, comprising at a secondary station the step of transmitting a feedback signal to the primary station on a random access channel, wherein the feedback signal being of—a dedicated type related to at least one point to point link between the considered secondary station and the primary station, or—a common type related to multicast links, wherein, depending on the transmission, the second part being related to a first type of multicast link or to a second type of multicast link.

Abstract: 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 behavior of the first station and the transmitter behavior corresponding to at least two non-contiguous ones of the quality ranges is identical.

Abstract: A method of operating a radio network, such as UMTS or cdma2000, which comprises at least one primary station (PS), i.e. and access point or bare station, and a plurality of secondary stations (SSI, SS2, SS3), i.e. mobile stations. The primary station determines the level of interest of the users of the secondary stations in a particular service, such as Multimedia Broadcasting and Multicast Services (MBMS), by allocating a respective plurality of access slots in which the secondary stations can transmit an indication of its interest. The primary station receives the indications of interest to and estimates the level of interest from the number of transmitted indications, for example whether or not they exceed a threshold value. Depending on the result of the estimation process the primary station selects a particular one of at least two transmission modes for transmitting the service.

Abstract: 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.

Abstract: Data is transmitted from a first station to a second station, by following method: at the first station, dividing the data into a sequence of data packets and transmitting the sequence of data packets; at the second station, receiving the data packets and transmitting acknowledgements indicating whether the data packets have been received successfully; at the first station, retransmitting as a sub-sequence of a plurality of sub-packets a data packet which has not been received successfully; and at the second station, reconstituting the data from the data packets and sub-packets; wherein the data packets comprise a sequence number providing an indication of position of each data packet within the sequence of data packets, and the sub-packets comprise a sub-packet indicator providing an indication of position of each sub-packet within the sub-sequence of sub-packets, and wherein the sequence numbers and sub-packet indicators include a plurality of numbers in common.
