Abstract
Official abstract text for this publication.
UE 100 selects a target cell used as a serving cell from a plurality of cells, based on a potential capacity of each of the plurality of cells operated at different frequencies. The potential capacity is defined by at least any one of a potential capacity of a frequency domain, a potential capacity of a time domain, and a potential capacity of a space domain.
First claim
Opening claim text (preview).
The invention claimed is: 1. A user terminal comprising: a controller configured to select a target cell used as a serving cell from a plurality of cells, based on a potential capacity of each of the plurality of cells operated at different frequencies, wherein the potential capacity is defined by at least any one of a bandwidth of the frequency at which the cell is operated, an allocatable resource of the cell in a time-axis direction to transmit user data, and a number of antennas the cell possesses, the controller is configured to select the target cell from cells having a quality that satisfies a predetermined quality criteria, the controller is configured to correct the quality, based on the potential capacity, and the controller is configured to identify the potential capacity of each of the plurality of cells, based on system information broadcast from each of the plurality of cells. 2. The user terminal according to claim 1 , wherein the controller is configured to more likely to select, as the target cell, a priority cell having the potential capacity that satisfies a predetermined capacity threshold value, compared to a cell having the potential capacity that does not satisfy the predetermined capacity threshold value. 3. The user terminal according to claim 1 , wherein the controller is configured to select, based on the potential capacity, the target cell from the cells having the quality that satisfies the predetermined quality criteria. 4. The user terminal according to claim 1 , wherein the information for identifying the potential capacity is included in one system information broadcast from each of the plurality of cells. 5. A mobile communication method comprising: selecting a target cell used as a serving cell from a plurality of cells, based on a potential capacity of each of the plurality of cells operated at different frequencies, the target cell being selected from cells having a quality that satisfies a predetermined quality criteria, and wherein the potential capacity is defined by at least any one of a bandwidth of the frequency at which the cell is operated, an allocatable resource of the cell in a time-axis direction to transmit user data, and a number of antennas the cell possesses; and correcting the quality based on the potential capacity, wherein the mobile communication method further comprises identifying the potential capacity of each of the plurality of cells, based on system information broadcast from each of the plurality of cells.
