Abstract
Official abstract text for this publication.
A terminal including: a reception unit configured to receive, from a base station apparatus of a serving cell, information indicating a relation between a frequency position of a resynchronization signal of the serving cell and a frequency position of a resynchronization signal of a neighbor cell, wherein the reception unit receives the resynchronization signal of the neighbor cell at a frequency position based on the relation.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A terminal comprising: a controller configured to determine a frequency position and a time position of a first resynchronization signal for a serving cell and a second resynchronization signal for a neighbor cell by using a cell ID; and a receiver configured to receive the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the frequency position and the time position, wherein the terminal receives a granularity of a time offset of the first resynchronization signal that is determined based upon a transmission periodicity of the first resynchronization signal, wherein the controller determines the frequency position and the time position based on a remainder of dividing the cell ID by a predetermined integer, wherein the terminal is configured to perform a measurement using the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell, and wherein the controller is configured to determine a same time offset for the first resynchronization signal and for the second resynchronization signal in a case where the frequency position of the first resynchronization signal and the second resynchronization signal are different. 2 . A base station comprising: a controller configured to determine a frequency position and a time position of a first resynchronization signal for a serving cell and a second resynchronization signal for a neighbor cell by using a cell ID; and a transmitter configured to transmit the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the frequency position and the time position, wherein the base station is configured to transmit a granularity of a time offset of the first resynchronization signal that is determined based upon a transmission periodicity of the first resynchronization signal, wherein the controller determines the frequency position and the time position based on a remainder of dividing the cell ID by a predetermined integer, wherein a terminal is configured to perform a measurement using the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell, and wherein the terminal is configured to determine a same time offset for the first resynchronization signal and for the second resynchronization signal in a case where the frequency position of the first resynchronization signal and the second resynchronization signal are different. 3 . A communication system comprising: a base station comprising: a controller configured to determine a frequency position and a time position of a first resynchronization signal for a serving cell and a second resynchronization signal for a neighbor cell by using a cell ID; and a transmitter configured to transmit the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the frequency position and the time position, and a terminal comprising: a controller configured to determine the frequency position and the time position of the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the cell ID; and a receiver configured to receive the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the frequency position and the time position, wherein the terminal receives a granularity of a time offset of the first resynchronization signal that is determined based upon a transmission periodicity of the first resynchronization signal, wherein the controller determines the frequency position and the time position based on a remainder of dividing the cell ID by a predetermined integer, wherein the terminal is configured to perform a measurement using the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell, and wherein the controller is configured to determine a same time offset for the first resynchronization signal and for the second resynchronization signal in a case where the frequency position of the first resynchronization signal and the second resynchronization signal are different. 4 . A communication method executed by a terminal, comprising: determining a frequency position and a time position of a first resynchronization signal for a serving cell and a second resynchronization signal for a neighbor cell by using a cell ID, wherein the frequency position and the time position are determined based on a remainder of dividing the cell ID by a predetermined integer; receiving the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell by using the frequency position and the time position; receiving a granularity of a time offset of the first resynchronization signal that is determined based upon a transmission periodicity of the first resynchronization signal; performing a measurement using the first resynchronization signal for the serving cell and the second resynchronization signal for the neighbor cell; and determining a same time offset for the first resynchronization signal and for the second resynchronization signal in a case where the frequency position of the first resynchronization signal and the second resynchronization signal are different.
