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 an expected maximum carrier frequency offset value, and a determination of a set of possible sequence values having a predetermined length, where each sequence value in the set is based upon a first maximum length sequence having a first cyclic shift, and is based upon a second maximum length sequence having a second cyclic shift. A subset of sequence values to be used as synchronization signal sequences for determining the identification of a communication target is selected from the set of possible sequence values. The selected subset of sequence values includes no more than one sequence value from any group of possible sequence values from the determined set where (a) a value of a 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, and (b) the 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 less than or equal to the determined expected maximum carrier frequency offset value. Each one of the selected subset of values is assigned to a respective one of the communication targets.
