Title:
UPLINK TRANSMISSION POWER DISTRIBUTION METHOD AND MOBILE COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/214283
Kind Code:
A1
Abstract:
Disclosed are an uplink transmission power distribution method and a mobile communication device. The method comprises the following steps: obtaining indication information, a physical uplink shared channel being transmitted at a first transmission time interval, and a corresponding demodulation reference signal being located at a second transmission time interval; determining a power distribution value of the physical uplink shared channel according to a power distribution priority of each channel, a transmission power requirement value of each channel at the first transmission time interval, and maximum transmission power; setting a power distribution priority for the demodulation reference signal; and by using the demodulation reference signal as a channel within the second transmission time interval, according to the power distribution value of the physical uplink shared channel, further determining a power distribution value of the demodulation reference signal. The device is applied to the method according to any embodiment of the present application, and comprises a network device and at least one terminal device. The present invention solves the problem that a physical uplink shared channel and a demodulation reference signal distribute channel power at different transmission time intervals.
