Abstract
The available transmission resources on a downlink-shared channel are divided into resource blocks, each resource block comprising a predetermined number of sub-carriers during a predetermined time period. The resource blocks are subdivided into localized resource blocks and distributed resource blocks. A user requiring sufficient resources can be allocated a plurality of said localized resource blocks. A user who would require only a small number of said localized resource blocks can instead be allocated subunits of a plurality of said distributed resource blocks.
Claims4
A method for achieving frequency diversity for scheduled transmissions of resource blocks on a downlink-shared channel of a telecommunication system, characterised by
- assigning resource blocks as either localized virtual resource blocks, or distributed virtual resource blocks,
- mapping the localized virtual resource blocks one-to-one to a set of physical resource blocks that are assigned for localized transmission,
- mapping each of the distributed virtual resource blocks for a plurality of terminals to the physical resource blocks assigned for distributed transmission.
