LOCALIZED AND DISTRIBUTED TRANSMISSION

摘要

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.

1. A method for achieving frequency diversity for scheduled transmissions of resource blocks on a downlink-shared channel between a network node and a plurality of terminals in a telecommunication system, comprising:
determining a total number NRB of physical resource blocks that are available for transmission on the downlink-shared channel; determining a number NDRB of the physical resource blocks that have been assigned for distributed transmission; determining a position of each of the physical resource blocks that have been assigned for distributed transmission as i*C, where i denotes a value in the sequence 0, 1, 2, . . . , (NDRB−1), and C is an integer defined according to the equation C=└(N_RB−1)/(N_DRB−1)┘; and receiving information that was transmitted using distributed transmission on the downlink-shared channel, according to the determined position of each of the physical resource blocks.
