Title:
上りパワー制御方法、パワー制御パラメータの配置方法及び装置
Document Type and Number:
Japanese Patent JP5669959
Kind Code:
B2
Abstract:
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 downlink sub-frames of N downlink carriers and generates uplink control information, wherein the uplink control information of the M downlink sub-frames is transmitted in one uplink sub-frame; the user equipment determines F_PUCCH (F) and h(n) for calculating the transmit power of a physical uplink control channel (PUCCH) according to whether the number of bits of the uplink control information is larger than a predefined threshold; F_PUCCH (F) represents the power offset of different PUCCH formats relative to the 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 transmit power according to F_PUCCH (F) and h(n), and sending the uplink control information on the PUCCH using the calculated transmit power. The present invention can improve the accuracy of power control, thus enhance the transmission performance of the uplink control information.
