Radio system and methods for duplex operation

A radio system providing a duplex telecommunication connection in a radio connection based on interactive communication using data frames in a first transmission direction and in a reverse second transmission direction, each data frame comprising a plurality of frame addresses, and properties of each radio connection being variable by allocation of frame addresses to it, wherein the system is arranged to

• compose information of interactive communication in the first transmission direction based on information transmitted in at least one previous frame in the second transmission direction,
• form the data frames in the first transmission direction and in the second transmission direction from at least two time-adjacent subframes, each subframe comprising at least two frame addresses,
• allocate the subframes in said first and second transmission direction to each interactive communication in such a way that the subframe in the first transmission direction and a subframe in the second transmission direction allocated with allocations to the same interactive communication do not overlap in time, but said subframes may overlap in time with subframes with allocations to another interactive communication.

A base station in a radio system providing duplex telecommunication connection in a radio connection based on interactive communication using data frames in a first transmission direction and in a reverse second transmission direction, each data frame comprising a plurality of frame addresses, and properties of each radio connection being variable by allocation of frame addresses to it, the base station comprising:

• a first system configured to compose information of interactive communication in the first transmission direction based on information received in at least one previous frame in the second transmission direction,
• a second system configured to form data frames in the first transmission direction from at least two time-adjacent subframes, each subframe comprising at least two frame addresses, and
• a third system configured to transmit subframes in said first transmission direction and receive subframes in the second transmission direction in such a way that a subframe in the first transmission direction and a subframe in the second transmission direction with allocations to the same interactive communication do not overlap in time, but said subframes may overlap in time with subframes with allocations to another interactive communication.

• a first system configured to compose information of interactive communication in the second transmission direction based on information received in at least one previous frame in the first transmission direction,
• a second system configured to form data frames in the second transmission direction from at least two time-adjacent subframes, each subframe comprising at least two frame addresses, and
• a third system configured to transmit subframes in said second transmission direction and receive subframes in the first transmission direction in such a way that a subframe in the first transmission direction and a subframe in the second transmission direction with allocations to the same interactive communication do not overlap in time, but said subframes may overlap in time with subframes with allocations to another interactive communication.

A device in a radio system, wherein the device provides duplex telecommunication connection in a radio connection based on a communication using data frames in a first direction and in a second direction, the device comprising:

• a first system configured to generate information of a communication in the first direction based on information received in at least one previous frame in the second direction,
• a second system configured to form data frames in the first direction from at least two time-adjacent subframes, and
• a third system configured to transmit subframes in said first direction and receive subframes in the second direction in such a way that a subframe in the first direction and a subframe in the second direction with allocations to the same communication do not overlap in time, but said subframes may overlap in time with subframes with allocations to another communication.
