Abstract
There is provided a method for determining uplink transmission power. The method may performed by a user equipment (UE) and comprise: receiving, by the UE, a value of additional maximum power reduction (A-MPR) from a base station (BS), if the UE is configured to use for uplink transmission a frequency range of 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz and if another UE which is located in an adjacent BS and is to be protected uses for an uplink transmission a frequency range of 2010 MHz through 2025 MHz; and determining an uplink transmission power by applying the value of A-MPR.

A method for determining uplink transmission power, the method performed by a user equipment (UE) and comprising:
- receiving, by the UE, a value of additional maximum power reduction (A-MPR) from a base station (BS), if the UE is configured to use for uplink transmission a frequency range of 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz and if another UE which is located in an adjacent BS and is to be protected uses for an uplink transmission a frequency range of 2010 MHz through 2025 MHz
- determining an uplink transmission power by applying the value of A-MPR,
- wherein if the UE is applied with −40 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 5 MHs, the value of A-MPR is 15 dB, and
- wherein if the UE is applied with −30 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 10 MHs, the value of A-MPR is 11 dB.
A method for limiting uplink transmission power of a first user equipment (UE), the method performed by a base station (BS), comprising:
- allocating, by the BS, uplink resource in frequency range 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz to the first UE if a second UE, which is located in an adjacent BS and is to be protected, uses for an uplink transmission a frequency range of 2010 MHz through 2025 MHz;
- transmitting, from the BS to the first UE, a value of additional maximum power reduction (A-MPR) to protect the second UE,
- wherein if the first UE is applied with −40 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 5 MHs, the value of A-MPR is 15 dB, and
- wherein if the first UE is applied with −30 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 10 MHs, the value of A-MPR is 11 dB.
A user equipment for transmitting uplink signals in a wireless communication system, comprising:
- a radio frequency (RF) unit;
- and
- a processor configured to decide an uplink transmission power by applying a value of additional maximum power reduction (A-MPR) received from a base station (BS) to protect another UE, which is located in an adjacent BS and uses for an uplink transmission a frequency range of 2010 MHz through 2025 MHz, if the RF unit of the UE is configured to use for an uplink transmission a frequency range of 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz;
- wherein if the UE is applied with −40 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 5 MHs, the value of A-MPR is 15 dB, and
- wherein if the UE is applied with −30 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 10 MHs, the value of A-MPR is 11 dB.
A base station for limiting uplink transmission power of a first user equipment (UE), comprising:
- a RF unit;
- and
- a processor configure to allocate uplink resource in frequency range 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz to the first UE if a second UE in an adjacent base station and to be protected uses for an uplink transmission a frequency range of 2010 MHz through 2025 MHz, and to transmit a value of additional maximum power reduction (A-MPR) for protecting the second UE to the first UE,
- wherein if the first UE is applied with −40 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 5 MHs, the value of A-MPR is 15 dB, and
- wherein if the first UE is applied with −30 dBm/MHz as a maximum limit of spurious emission for coexistence requirement with the adjacent another UE, and if a transmission bandwidth allocated for the uplink transmission of the UE is 10 MHs, the value of A-MPR is 11 dB
