Abstract: An embodiment power control method includes obtaining, by a base station, a bit error rate (BER) of a physical uplink control channel (PUCCH) of a UE at a subframe i, and sending a transmit power control command ??PUCCH(i?km) having a value related to a transmit power control command obtained by the base station at a subframe i?km and that is determined according to the relationship of the BER to a bit error rate reference value. An embodiment base station includes a second obtaining unit configured to obtain a BER of a PUCCH of a UE at a subframe i and a second sending unit configured to send a transmit power control command ??PUCCH(i?km) having a value related to a transmit power control command obtained by the base station at a subframe i?km and that is determined according to the relationship of the BER to a bit error rate reference value.

Abstract: The embodiments of the present invention provide a power control method and a base station. The method includes: obtaining, by a base station, INPUCCH(i), where the INPUCCH(i) is average interference noise power of a physical uplink control channel (PUCCH) carried by radio resources that are allocated by the base station at a subframe i; and sending, by the base station, a parameter PO—NOMINAL—PUCCH(i) for power control at the subframe i. In the embodiments of the present invention, the base station may send a more accurate parameter to a UE, so that PUCCH transmit power which is at the subframe i and calculated by the UE is more accurate, and network interference caused by increasing the PUCCH transmit power is further reduced.

Abstract: A power control method and a base station are disclosed. The method includes obtaining, by a base station, INPUCCH(i). The INPUCCH(i) is an average interference noise power of a physical uplink control channel (PUCCH) carried by radio resources that are allocated by the base station at a subframe i. The base station sends a parameter P0—NOMINAL—PUCCH(i) for power control at the subframe i.
