Abstract

A terminal includes: a control section that generates Capability information including UE Capability for a Power Class; and a transmission section that transmits the Capability information. The Power Class is specified by four items of Max Total Radiated Power (TRP), Max peak Equivalent Isotropic Radiated Power (EIRP), Min peak EIRP, and Spherical coverage EIRP, and an Inter-band-Carrier-Aggregation (CA) specified value of at least one of the Max peak EIRP and the Min peak EIRP for Inter-band CA in which a plurality of bands are used is defined by a method different from a method for a non-Inter-band-CA specified value.

Claims (21)

1. A terminal comprising:

a control section that generates Capability information including a Power Class of a terminal; and

a transmission section that transmits the Capability information,

wherein a spherical coverage EIS is specified for each of a plurality of the Power Classes,

wherein, in at least one of the plurality of Power Classes, a specified value of the spherical coverage EIS is determined by a method different between Inter-band Carrier Aggregation (CA) using a plurality of bands and a case other than the Inter-band CA, and

wherein the specified value of the spherical coverage EIS for a first band and the specified value of the spherical coverage EIS for a second band in the Inter-band CA are determined independently of each other in a same beam direction in two of the first and the second bands.

2. The terminal according to claim 1 , wherein a Peak Effective Isotropic Sensitivity (EIS) is specified for each of a plurality of the Power Classes, and,

in at least one of the plurality of Power Classes, a specified value of the Peak EIS is determined by a method different between the Inter-band CA and a case other than the Inter-band CA,

wherein the specified value of the Peak EIS for the first band and the specified value of the Peak EIS for the second band in the Inter-band CA are determined independently of each other.

3. A system, comprising:

a terminal that generates Capability information including a Power Class of the terminal, and transmits the Capability information; and

a base station that receives the Capability information,

wherein a spherical coverage Effective Isotropic Sensitivity (EIS) is specified for each of a plurality of the Power Classes,

wherein, in at least one of the plurality of Power Classes, a specified value of the spherical coverage EIS is determined by a method different between Inter-band Carrier Aggregation (CA) using a plurality of bands and a case other than the Inter-band CA, and

wherein the specified value of the spherical coverage EIS for a first band and the specified value of the spherical coverage EIS for a second band in the Inter-band CA are determined independently of each other in a same beam direction in two of the first and the second bands.

4. A communication method performed by a terminal, comprising:

generating Capability information including a Power Class; and

transmitting the Capability information,

wherein a spherical coverage Effective Isotropic Sensitivity (EIS) is specified for each of a plurality of the Power Classes,

wherein, in at least one of the plurality of Power Classes, a specified value of the spherical coverage EIS is determined by a method different between Inter-band Carrier Aggregation (CA) using a plurality of bands and a case other than the Inter-band CA, and

wherein the specified value of the spherical coverage EIS for a first band and the specified value of the spherical coverage EIS for a second band in the Inter-band CA are determined independently of each other in a same beam direction in two of the first and the second bands.
