Abstract
A communication system employs discontinuous transmission to create gaps in transmission during which a transmitting device (200) can receive. When the transmission of a data block coincides with a transmission gap such that a portion of the data block is not transmitted, the block is retransmitted later. Prior to the retransmission, the data in the data block is reordered. The reordering may be predetermined, or may be selected to ensure that the same portion of data does not coincide with a transmission gap in the retransmission.
Claims11
A method of transmitting data in a communication system employing first predetermined time periods for the transmission of data and second predetermined time periods for transmission gaps, the method comprising:
- dividing the data into data blocks;
- transmitting the respective data blocks during respective first predetermined time periods, subject to refraining from transmitting portions of the data blocks coinciding with the second predetermined time periods;
- retransmitting at least those data blocks transmitted during those first predetermined time periods which overlap any of the second predetermined time periods;
- and
- reordering the data in the retransmitted data blocks prior to the retransmission.
Apparatus (200) for transmitting data in a communication system employing first predetermined time periods for the transmission of data and second predetermined time periods for transmission gaps, the apparatus (200) comprising:
- means (220) for inhibiting transmission during the second predetermined time periods;
- means (230) for dividing the data into data blocks;
- means (250, 240, 210) for transmitting the respective data blocks during respective first predetermined time periods, subject to refraining from transmitting portions of the data blocks coinciding with the second predetermined time periods;
- means (240) for retransmitting at least those data blocks transmitted during those first predetermined time periods which overlap any of the second predetermined time periods;
- and
- means (260) for reordering the data in the retransmitted data blocks prior to the retransmission.
