eu sho node bs 310 only one copy will be stored in a re ordering buffer not shown maintained by a re ordering function entity 315 in the c rnc 305 as a correctly received data block and any extra received copies of the successfully decoded data block are discarded as redundant data step 430 finally in step 435 the successfully decoded data block is processed by the re ordering function entity 315 in the c rnc 305 which performs a re ordering procedure on those successfully decoded data blocks that are correctly received in the re ordering function entity 315 so as to support in sequence delivery to the higher protocol layers 325 process 400 is beneficial because data blocks received from different eu sho node bs 310 can be combined and organized in sequence for delivery to the higher protocol layers 325 provided that these node bs 310 have the same c rnc 305 this is frequently the case although its applicability is somewhat more restrictive than placing a re ordering function in an s rnc 105 however this restriction is offset by other considerations for example a benefit of c rnc operation is reduced latency for h arq operation the performance benefits of minimizing this latency are well understood in the art during.
