Patent ID: 8711722

Claim:
A method for processing power headroom, comprising: when transmitting a physical uplink shared channel (PUSCH) and/or a physical uplink control channel (PUCCH) on a subframe and a component carrier group, a terminal measuring a power headroom on the subframe and the component carrier group; and the terminal reporting the power headroom to a base station and indicating the type of the reported power headroom when reporting; wherein when the terminal simultaneously transmits the PUSCH and the PUCCH on the subframe and the component carrier group, the measured power headroom on the subframe and the component carrier group is one of: PH PUCCH+PUSCH (i,j); PH′ PUCCH+PUSCH (i,j); PH PUSCH (i,j) and PH PUCCH (i,j); PH PUCCH+PUSCH (i,j) and PH PUCCH (i,j); PH′ PUCCH+PUSCH (i,j) and PH PUCCH (i,j); PH PUCCH+PUSCH (i,j) and PH PUSCH (i,j); PH′ PUCCH+PUSCH (i,j) and PH PUSCH (i,j); PH PUCCH+PUSCH (i,j) and PH PUSCH (i,j) and PH PUCCH (i,j); and PH′ PUCCH+PUSCH (i,j) and PH PUSCH (i,j) and PH PUCCH (i,j); in which, i is the subframe, and i is the component carrier group; PH PUCCH + PUSCH ⁡ ( i , j ) = ⁢ 10 ⁢ ⁢ log 10 ⁡ ( 10 P CMAX ⁡ ( j ) / 10 - 10 P PUCCH ′ ⁡ ( i , j ) / 10 ) - ⁢ P PUSCH ′ ⁡ ( i , j ) = ⁢ 10 ⁢ ⁢ log 10 ⁡ ( 10 P CMAX ⁡ ( j ) / 10 - 10 P PUCCH ′ ⁡ ( i , j ) / 10 10 P PUSCH ′ ⁡ ( i , j ) / 10 ) , PH PUCCH + PUSCH ′ ⁡ ( i , j ) = ⁢ P CMAX ⁡ ( j ) - ⁢ 10 ⁢ ⁢ log 10 ⁡ ( 10 P PUSCH ′ ⁡ ( i , j ) / 10 + 10 P PUCCH ′ ⁡ ( i , j ) / 10 ) = ⁢ 10 ⁢ ⁢ log 10 ⁡ ( 10 P CMAX ⁡ ( j ) / 10 10 P PUSCH ′ ⁡ ( i , j ) / 10 + 10 P PUCCH ′ ⁡ ( i , j ) / 10 ) , ⁢ PH PUSCH ⁡ ( i , j ) = P CMAX ⁡ ( j ) - P PUSCH ′ ⁡ ( i , j ) , ⁢ ⁢ PH PUCCH ⁡ ( i , j ) = P CMAX ″ ⁡ ( j ) - P PUCCH ′ ⁡ ( i , j ) , in which, P′ PUSCH (i,j) is the transmitting power, which is estimated by the terminal, of the PUSCH transmitted on the subframe i and the component carrier group j; P′ PUCCH (i,j) is the transmitting power, which is estimated by the terminal, of the PUCCH transmitted on the subframe i and the component carrier group j; and P CMAX (j) is the configured maximum output power, which is set by the terminal, on the subframe i and the component carrier group j; and P′ CMAX (j)=P″ CMAX (j)=P CMAX (j) is the configured maximum output power, which is set by the terminal, on the subframe i and the component carrier group j; or P′ CMAX (j) is the configured maximum output power on the component carrier group j, which is set by the terminal supposing that there is only the PUSCH transmitted on the component carrier group j; and P″ CMAX (j) is the configured maximum output power on the component carrier group j, which is set by the terminal supposing that there is only the PUCCH transmitted on the component carrier group j.
