Abstract:
A method (100) of transmitting data blocks (TB1, TB2, . . . , TBn) from at least two radio base stations (NBa; NBb) employing macrodiversity over at least two diversity links (a; b) to a central station (RNC), comprising:transmitting the data blocks (TB1, TB2, . . . , TBn) from the base stations (NBa; NBb) to the central station (RNC) together with check fields (CID1, CID2, . . . , CIDn) within data frames (F; Fâ€²), with each (TB1) of the data blocks being assigned one (CID1) of the check fields; analyzing the check fields for each of the diversity links (a; b) at the central station (RNC) to identify those data blocks which were correctly received; and replacing, at the central station (RNC), erroneous data blocks (TB1) received over one (a) of the diversity links with correct data blocks (TB1â€²) received over another one (b) of the diversity links, wherein, in each data frame (F), the data blocks (TB1, TB2, . . . , TBn) are arranged immediately side by side (step 111), with each data block (TB1) containing a number of bits divisible by 8, and wherein each data frame (F) contains a check block (CB) into which the check fields (CID1, CID2, . . . , CIDn) are inserted.
