UPLINK POWER CONTROL METHOD, POWER CONTROL PARAMETER CONFIGURATION METHOD AND APPARATUS THEREOF

摘要

Disclosed are an uplink power control method, power control parameter configuration method and apparatus thereof. The uplink power control method comprises: a user equipment receives data in M number of downlink sub-frames of N number of downlink carrier and generates uplink control information, wherein the uplink control information of the M number of downlink sub-frames is transmitted in a same uplink sub-frame; the user equipment determines ?F_PUCCH(F) and h(n) for calculating the transmission power of a physical uplink control channel (PUCCH) according to whether the number of bits of the uplink control information is greater than a preset threshold; ?F_PUCCH(F) represents the power offset of PUCCHs in different formats relative to PUCCH format la, h(n) represents the power offset corresponding to the number of transmission bits of the PUCCH; the user equipment calculates the PUCCH transmission power according to ?F_PUCCH(F) and h(n), and sending the uplink control information on the PUCCH using the calculated transmission power. The present invention can improve the accuracy of power control, thus enhancing the transmission performance of the uplink control information.
