Abstract
The invention discloses an uplink power control calculation method and device, relates to the field of wireless communication, and is used for uplink power control calculation. The uplink power control calculation method comprises the steps that network equipment acquires base station receiving antenna diversity gain, base station transmitting antenna beamforming gain, terminal receiving antenna diversity gain and terminal transmitting antenna beamforming gain; the network equipment calculates an uplink and downlink antenna system gain difference delta G according to the base station receivingantenna diversity gain, the base station transmitting antenna beamforming gain, the terminal receiving antenna diversity gain and the terminal transmitting antenna beamforming gain; the network device sends the uplink and downlink antenna system gain difference delta G to the terminal device; the terminal equipment receives the uplink and downlink antenna system gain difference delta G sent by the network equipment; and the terminal equipment calculates uplink power control according to the uplink and downlink antenna system gain difference delta G. The embodiment of the invention is appliedto uplink power control calculation.
Description
technical field [0001] The present application relates to the field of wireless communication, and in particular to an uplink power control calculation method and device. Background technique [0002] In the current uplink power control algorithm, the initial open-loop power control is based on estimating the downlink path loss (path loss, PL) of the user equipment (user equipment, UE). The UE performs downlink PL estimation by measuring the downlink reference signal receiving power (reference signal receiving power, RSRP) and subtracting it from the known reference signal power. [0003] In the 4th generation mobile communication technology (4G) network, the antenna of the 4G base station is basically 2 transmit modules (transmit, T) 2 receive modules (receive, R), 4T4R or 8T8R, the antenna of the 4G terminal It is basically 1T2R. Therefore, the difference in the number of antennas between the terminal and the base station in the 4G network is not large, and the gain of th...
