Abstract
A network includes a first transceiving station and a further transceiving station. In one arrangement the data is transmitted from the first transceiving station to the second transceiving station according to a frame structure having a payload portion for payload data and a synchronization portion for synchronization data. The frame structure is selected from candidate frame structures having differing durations of the synchronization portion, according to a data loading factor which depends on the amount of data that is required to be transmitted. The payload capacity may be optimised by reducing the duration of the synchronization portion when a large amount of data is required to be transmitted.
Claims23
A method of transmitting data in a network, said network comprising a first transceiving station and a further transceiving station, said method comprising transmitting data in a sequence of frames, and for each frame of the sequence of frames:
- selecting a frame structure of a frame, wherein said frame structure comprises a synchronization portion for transmitting synchronization data and one or more further portions for transmitting and/or receiving data different from said synchronization data;
- and
- transmitting data from said first transceiving station to said further transceiving station according to the selected frame structure,
- in which said selecting comprises:
- selecting a first frame structure for a first frame of said sequence of frames, the first frame structure having a first synchronization portion of a first length;
- and
- selecting a second frame structure for a second frame of said sequence of frames, the second frame structure having a synchronization portion of a second length,
- the first and second frame structures being selected according to an amount of data to be transmitted and/or received within said one or more further portions of said first and second frames, respectively,
- such that:
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is smaller than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first length is selected to be longer than said second length;
- and
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is larger than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first length is selected to be shorter than said second length.
A transceiving station for transmitting data, said transceiving station being configured to transmit data in a sequence of frames according to a selectable frame structure, said frame structure comprising a synchronization portion for transmitting synchronization data and one or more further portions for transmitting and/or receiving data different from said synchronization data, wherein said transceiving station is configured to:
- select a first frame structure for a first frame of said sequence of frames, the first frame structure having a first synchronization portion of a first length;
- and
- select a second frame structure for a second frame of said sequence of frames, the second frame structure having a synchronization portion of a second length,
- the first and second frame structure being selected according to an amount of data to be transmitted and/or received within said one or more further portions of said first and second frames respectively,
- such that:
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is smaller than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first length is selected to be longer than said second length;
- and
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is larger than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first length is selected to be shorter than said second length.
A computer program product comprising a non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to perform a method for transmitting data in a network, said network comprising a first transceiving station and a further transceiving station, said method comprising said method comprising transmitting data in a sequence of frames, and for each frame of the sequence of frames:
- selecting a frame structure of a frame, wherein said frame structure comprises a synchronization portion for transmitting synchronization data and one or more further portions for transmitting and/or receiving data different from said synchronization data;
- and
- transmitting data from said first transceiving station to said further transceiving station according to the selected frame structure,
- in which said selecting comprises:
- selecting a first frame structure for a first frame of said sequence of frames, the first frame structure having a first synchronization portion of a first length;
- and
- selecting a second frame structure for a second frame of said sequence of frames, the second frame structure having a synchronization portion of a second length,
- the first and second frame structures being selected according to an amount of data to be transmitted and/or received within said one or more further portions of said first and second frames respectively, such that:
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is smaller than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first frame is selected to be longer than said second length;
- and
- if the amount of data to be transmitted and/or received within said one or more further portions of the first frame is larger than the amount of data to be transmitted and/or received within the one or more further portions of the second frame, then said first length is selected to be longer than said second length.
