Abstract

Claims (22)

1. A terminal comprising:

a processor that determines activation or deactivation for a Reference Signal (RS) group; and

a transmitter that transmits a first report related to a determination, by the processor, of activation or deactivation for the RS group by including the first report in Medium Access Control control information (MAC CE),

wherein the processor performs a second report related to activation or deactivation for a plurality of RS groups in a single report, and

wherein the processor controls transmission of the second report, based on an expiry of a timer or received power of a RS.

2. A radio communication method for a terminal, comprising:

determining activation or deactivation for a Reference Signal (RS) group, and

transmitting a first report related to determined activation or deactivation for the RS group by including the first report in Medium Access Control control information (MAC CE),

wherein a second report related to activation or deactivation for a plurality of RS groups performs in a single report, and

wherein transmission of the second report is controlled based on an expiry of a timer or received power of a RS.

3. A base station comprising:

a transmitter that transmits information for indicating activation or deactivation for a Reference Signal (RS) group; and

a receiver that receives a first report related to determined activation or deactivation for the RS group by including the first report in Medium Access Control control information (MAC CE),

wherein a second report related to activation or deactivation for a plurality of RS groups is performed in a single report in the MAC CE, and

wherein the second report is transmitted based on an expiry of a timer or received power of a RS.

4. A system comprising a terminal and a base station, wherein the terminal comprises:

a processor that determines activation or deactivation for a Reference Signal (RS) group; and

a transmitter that transmits a first report related to a determination, by the processor, of activation or deactivation for the RS group by including the first report in Medium Access Control control information (MAC CE),

wherein the processor performs a second report related to activation or deactivation for a plurality of RS groups in a single report, and

wherein the processor controls transmission of the second report, based on an expiry of a timer or received power of a RS; and

the base station comprises:

a receiver that receives the MAC CE.
