Problems solved by technology

In the prior art, for NR terminals to transmit uplink signals on the shared uplink carrier of the LTE base station, the downlink path loss measured on the NR high-frequency downlink carrier is used as the uplink loss on the shared uplink carrier to calculate the uplink signal The transmit power will lead to the degradation of the uplink transmission performance of NR terminals, and even affect the uplink transmission of LTE terminals. input preamble

Embodiment Construction

[0079] In order to facilitate understanding, the illustrations of concepts related to this application are given for reference, as follows:

[0080] A base station (base station, BS) device, also referred to as a base station, is a device deployed in a radio access network to provide a wireless communication function. For example, the equipment providing base station function in 2G network includes base transceiver station (base transceiver station, BTS) and base station controller (base station controller, BSC), and the equipment providing base station function in 3G network includes Node B (English NodeB) and wireless Network controller (radio network controller, RNC), the device that provides base station function in 4G network includes evolved Node B (evolved NodeB, eNB), in WLAN, the device that provides base station function is access point (access point, AP) . In future 5G networks such as New Radio (NR) or LTE+, devices that provide base station functions include Node...

Abstract

The application discloses a method and a device for determining uplink signal transmission power. The method comprises: a terminal device receives a message sent by a network device, wherein the message carries a first loss parameter relating to a first uplink carrier and a second loss parameter related to a second uplink carrier; the terminal device calculates transmit power of an uplink signal,wherein the uplink signal is sent by using the first uplink carrier and the transmit power of the uplink signal is calculated on the basis of the first loss parameter relating to the first uplink carrier, or the uplink signal is sent by using the second uplink carrier and the transmit power of the uplink signal is calculated on the basis of the second loss parameter relating to the second uplink carrier. The method and device provided by the invention may ensure the uplink transmission performance of an NR base station, and reduce uplink transmission to an LTE base station.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for determining the transmit power of an uplink signal. Background technique [0002] Currently, in the fifth generation mobile communication system, two types of base stations are mainly proposed, namely, a long term evolution (Long Term Evolution, LTE) base station and a new radio interface (New Radio, NR) base station. For these two types of base stations, the functions are similar, and the main difference is the deployment frequency band. In the prior art, NR base stations are mainly deployed in high-frequency bands, while LTE base stations are mainly deployed in low-frequency bands. In a wireless communication system, the higher the frequency of the carrier, the greater the path loss and the worse the uplink coverage. However, since NR base stations are deployed in high-frequency bands, NR base stations have the problem of l...
