    Abstract: A mobile telephone network operating general packet radio service includes a base station (2) and a group of mobile telephones (M1 to M4).
    The base station (2) includes a control unit (8) which generates a succession of data packets which are transmitted along a common downlink to all the mobiles (M1 to M8).
    Each data packet includes a header section containing an uplink state flag identifying a first selected mobile, to poll that mobile and cause it to return a packet of data to the base station along a common uplink channel. The header also includes an uplink state flag identifying a second selected mobile and is accompanied by the identity of and time slot for a second auxiliary uplink channel for polling the second mobile to cause the second mobile to return a packet of data to the base station along said auxiliary uplink channel thereby enabling the polling of at least two mobiles using the same data packet.
    The polling sequence produced by the control unit (8) ensures that each mobile is polled twice during each polling cycle, once accompanied with the identity of and time slot for a secondary auxiliary uplink channel and once without.

    Abstract: In the GPRS, a method of decoding uplink status having reduced interleaving depth in a RLC/MAC block is proposed; for RT-EGPRS users, all of the uplink flag bits are provided in the first burst of the four bursts; and for EGPRS users, nine bits of the uplink status flags are provided in the first burst of the RLC/MAC block and the remaining bits in the next three bursts. On receiving the first nine bits, a mobile performs an autocorrelation to identify the USF whether it belongs to the EGPRS or to the RT-EGPRS group.

    Abstract: The key of the invention is to introduce an interoperability device in a communication system which integrates an IEEE 802.11 transceiver and a Bluetooth transceiver. The device prevents that one transceiver is transmitting while the other is receiving, which would cause interference at the receiving transceiver. In addition, the device preferably prevents that both systems are transmitting at the same time to avoid interference at the receiving device(s). Optionally the device prohibits simultaneous reception of both transceivers. In that way the radio receiver can be shared between the devices, allowing a cheaper and smaller hardware design.

    Abstract: The dimensions of a resonator filter comprising at least one puck (12, 14) in a metal cavity (16) are calculated by deriving the diameter c and thickness j? of the puck, the spacing of the puck from the cavity walls by a mode-matching technique, then optimised by applying electromagnetic simulation of a full filter response. Other dimensions of the puck may also be optimised. If two or more pucks are present in the cavity, the inter-puck spacing is also optimised.
