INTEGRATED CIRCUIT FOR SEQUENCE REPORTING AND SEQUENCE GENERATION

摘要

Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.

1. An apparatus, comprising:
one or more memories; and circuitry coupled to the one or more memories, wherein the circuitry, in operation:
allocates at least two consecutive sequences of an arrangement of a plurality of sequences, each of the plurality of sequences having a difference between a position of a correlation value that occurs at a wrong timing and a position of a correlation value that occurs at a correct timing, the plurality of sequences being arranged in accordance with the differences and the arrangement including:
a first subset of the plurality of sequences arranged such that the differences generally increase in the arrangement of the first subset; anda second subset of the plurality of sequences arranged such that the differences generally decrease in the arrangement of the second subset; andreports allocated-sequence information.
