Abstract

A terminal includes: a receiving unit of receiving first information for configuring scheduling and second information for executing scheduling from a base station; and a control unit that identifies a single scheduled carrier or a plurality of scheduled carriers, based on the first information and the single second information.

Claims (21)

1. A terminal comprising:

a receiver that receives, from a base station, first information indicating a codepoint of a field for designating a group comprising one or more cells to be scheduled, via an RRC (Radio Resource Control) layer;

a processor that determines, based on the first information, a bit field configuration,

wherein the receiver receives, from the base station, second information including the field to which the bit field configuration applies, and

wherein the processor identifies, based on the group indicated by the field and contained in the first information, one or more cells to be scheduled; and

a transmitter that transmits an uplink shared channel in a cell indicated by the second information.

2. The terminal according to claim 1 , wherein the second information is downlink control information.

3. The terminal according to claim 1 , wherein the receiver receives a downlink shared channel in a cell indicated by the second information.

4. The terminal according to claim 1 , wherein the terminal dynamically switches, based on the second information, between a cell configured to receive a downlink shared channel and a cell configured to transmit an uplink shared channel.

5. A base station comprising:

a transmitter that transmits, to a terminal, first information indicating a codepoint of a field for designating a group comprising one or more cells to be scheduled, via an RRC (Radio Resource Control) layer;

a processor that determines, based on the first information, a bit field configuration,

wherein the transmitter transmits second information including the field to which the bit field configuration applies to the terminal, and

wherein the processor identifies, based on the group indicated by the field and contained in the first information, one or more cells to be scheduled; and

a receiver that receives an uplink shared channel in a cell indicated by the second information.

6. A communication method performed by a terminal, the communication method comprising:

receiving, from the base station, first information indicating a codepoint of a field for designating a group comprising one or more cells to be scheduled via an RRC (Radio Resource Control) layer;

determining, based on the first information, a bit field configuration;

receiving, from the base station, second information including the field to which the bit field configuration applies;

identifying, based on the group indicated by the field and contained in the first information, one or more cells to be scheduled; and

transmitting an uplink shared channel in a cell indicated by the second information.
