METHOD AND APPARATUS FOR ESTABLISHING A SET OF A PLURALITY OF SYNCHRONIZATION SIGNAL SEQUENCES TO BE USED WITH ONE OR MORE COMMUNICATION TARGETS

摘要

A method and apparatus provides a determination of a set of sequence values to be used as synchronization signal sequences, the set of sequence values having a predetermined length. Each sequence value in the set is based upon a first maximum o length sequence having a first cyclic shift, and is based upon a second maximum length sequence having a second cyclic shift. For at least one group of possible sequence values from the determined set, where a value of a cyclic shift difference between the second cyclic shift of the second maximum length sequence and the first cyclic shift of the first maximum length sequence upon which each of the possible sequence values in the group are based are equal, a cyclic shift difference between the respective first cyclic shift value of the first maximum length upon which each of the possible sequence values in the group are based for any two of the possible sequence values in the group are larger than or equal to a threshold value, where the threshold value is determined based on an expected maximum carrier frequency offset value. The method further includes assigning each one of the determined set of sequence values to respective at least one communication target of a plurality of communication targets.
