Example Embodiment

[0025] In order to facilitate the understanding of the embodiments of the present invention, the following technical points are introduced first:

[0026] When the new air interface (New Radio, NR) operates on an unlicensed frequency, before using a certain channel (channel, 20MHz) for transmission, the transmitter (terminal or base station) should listen before talking (ListenBefore Talk, LBT) A program that detects the channel to determine whether the channel is available. The specific method is that the transmitter measures the power received on the channel. If the received power is higher than a preset value (the preset value is used to determine whether it is occupied), then the channel will be determined to be occupied. state. Otherwise, the channel is determined to be unoccupied and can be used for NR signal transmission.

[0027] Currently, there are several types of LBT. For physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and physical downlink s

Abstract

The embodiment of the invention provides an uplink transmission method and equipment. The method comprises the following steps: receiving load control information from a local cell or a neighbor cell; and adjusting the uplink transmission of the first service of the local cell or the neighbor cell according to the load control information. In the embodiment of the invention, the terminal can receive the load control information from the local cell or the adjacent cell, and then the terminal can adjust the uplink transmission of the first service of the local cell or the adjacent cell according to the load control information, so that the influence of the uplink transmission of the first service on the uplink transmission of other services is avoided, and the user experience is improved. Namely, resource occupation and/or interference of the first service can be reduced, and QoS guarantee of other services is enhanced.
