Abstract

A terminal includes a receiver configured to receive first system information from a base station; and a controller configured to acquire, from the first system information, a first list, a second list, and a third list for scheduling second system information other than the first system information, and to determine a start position of a window for acquiring the second system information, based on the first list, the second list, and the third list, wherein the receiver receives the second system information from the base station in the window.

Claims (29)

1 . A terminal comprising:

a receiver configured to receive first system information from a base station; and

a controller configured to acquire, from the first system information, a first list, a second list, and a third list for scheduling second system information other than the first system information, and to determine a start position of a window for acquiring the second system information, based on a position of scheduling information of the second system information in a list, wherein the first list, the second list, and the third list are concatenated in this order in the list,

wherein the receiver receives the second system information from the base station in the window,

the second list schedules extended system information and does not schedule system information scheduled by the first list, and

the third list schedules system information related to position information.

2 . A communication method comprising:

causing a terminal to perform

receiving of first system information from a base station;

acquiring of, from the first system information, a first list, a second list, and a third list for scheduling second system information other than the first system information, and determining of a start position of a window for acquiring the second system information, based on a position of scheduling information of the second system information in a list, wherein the first list, the second list, and the third list are concatenated in this order in the list;

receiving of the second system information from the base station in the window,

the second list schedules extended system information and does not schedule system information scheduled by the first list, and

the third list schedules system information related to position information.

3 . A base station comprising:

a controller configured to schedule second system information other than first system information, and to include, in first system information, a first list, a second list, and a third list for indicating a start position of a window for acquiring the second system information by a terminal based on a position of scheduling information of the second system information in a list, wherein the first list, the second list, and the third list are concatenated in this order in the list; and

a transmitter configured to transmit the first system information to the terminal,

wherein the transmitter transmits the second system information to the terminal,

the second list schedules extended system information and does not schedule system information scheduled by the first list, and

the third list schedules system information related to position information.

4 . A wireless communication system comprising: a base station; and a terminal, wherein

the base station includes:

a controller configured to schedule second system information other than first system information, and to include, in first system information, a first list, a second list, and a third list for indicating a start position of a window for acquiring the second system information by a terminal; and

a transmitter configured to transmit the first system information to the terminal,

wherein the transmitter transmits the second system information to the terminal, and the terminal includes:

a receiver configured to receive the first system information from the base station; and

a controller configured to acquire, from the first system information, a first list, a second list, and a third list, and to determine a start position of a window for acquiring the second system information, based on a position of scheduling information of the second system information in a list, wherein the first list, the second list, and the third list are concatenated in this order in the list,

wherein the receiver receives the second system information from the base station in the window,

the second list schedules extended system information and does not schedule system information scheduled by the first list, and

the third list schedules system information related to position information.
