Problems solved by technology

However, while this may be relatively straightforward in the base stations of existing communication systems, a multi-carrier solution would require major changes in mobile terminals, as these would have to handle multiple channels simultaneously in the analog and digital parts

Embodiment Construction

[0050] In the drawings, the same reference numerals will be used for corresponding or similar elements.

[0051] The present invention involves transmitting and receiving data blocks on a plurality, ie at least two, of data carriers in order to increase the probability that a receiving unit successfully receives and detects a data block. A first aspect of the invention provides a method and means for selecting and receiving data blocks transmitted simultaneously on multiple data carriers. A second aspect of the invention relates to a method, system and network node for simultaneously transmitting data blocks on multiple data carriers.

[0052] figure 1 is a schematic overview of a communication system 1 employing the present invention. In this illustrative system 1, four mobile terminals or units 100-1 to 100-4 present in the radio coverage area 205-1 of a network node or base station 200-1 participate in a communication session with the base station 200-1 . The communicat...

Abstract

The invention names a multi-carrier wave dispatch. The invention provides a dispatch of data blocks on multi-data carrier waves (310 and 320) and monitor selection of data carrier waves. During a communication conversation period of the dispatch and at least one participant received unit (100), an emitting unit (200-1) simultaneously emits at least first data blocks (14) on the first data carrier wave (310) and emits second data blocks (22) on the second data carrier wave (320), based on the receiving quality of previously received data blocks (12), the receiving unit (100) selects which one of the data carrier waves (310 and 320) to be monitored, namely the first data blocks (14) or the second data blocks (22) are received, and at least one of the first and second data blocks (14 and 22) is based on sharing information with the data block (14 and 22) and the previously received data blocks (12), for example, the firs data blocks (14 ) or the second data blocks (22) are re-emitting edition of the previously received data blocks (12).

Description

[0001] This application is a divisional application of the invention patent application with the application number 200580049737.1, the application date is May 11, 2005, and the invention name is "multi-carrier scheduling". technical field [0002] The present invention relates generally to data block scheduling in radio communication systems, and more particularly to scheduling the transmission and reception of data blocks over multiple data carriers. Background technique [0003] Utilization of radio resources and channels is continuously subject to much research and development in order to optimize system throughput due to limited utilization of radio resources in communication systems. This is especially true when introducing new communication services into existing communication systems. An example of this type of new communication service is Multimedia Broadcast Multicast Service (MBMS). The advantage of this MBMS service is that it can use the same physical channel t...
