Problems solved by technology

[0003] When the required signal coverage area is relatively large, or there are multiple slave nodes attached to a master node, and the distance between each slave node and the master node is relatively large, the path loss from each slave node to the master node is different, and there will be mutual Inhibition problem, while the existing technical solutions do not consider the aforementioned suppression problem

Embodiment Construction

[0021] As mentioned in the background technology, the existing multi-node repeater does not consider the problem of mutual suppression between slave nodes, and does not perform system power control, which leads to the following problems in practical applications:

[0022] Since the attenuation (i.e., path loss) of the path between the master node and each slave node is different, when the uplink transmission of the slave node with small path loss is transmitted at the maximum transmission power, the uplink gain of the master node will be severely compressed, resulting in path The uplink gain of the path between the slave node with large path loss and the master node is insufficient, resulting in a reduced signal coverage area of ​​the slave node with large path loss, and poor signal coverage effect.

[0023] Specifically, the repeater has a rated gain and maximum uplink and downlink transmit power.

[0024] The gain of master node and slave node can be expressed based on the f...

Abstract

The invention discloses a method and a device for determining the transmitting power of a multi-node repeater, a storage medium and a terminal, and the method comprises the steps: receiving a broadcast signal which comprises the input power of an uplink gain compression point of a main node in the multi-node repeater; determining path loss of a path with the main node; and determining the maximumuplink transmitting power according to the input power of the uplink gain compression point and the path loss. Through the scheme provided by the invention, the uplink of each slave node in the multi-node repeater can be ensured to be in a balanced state, and the situation of mutual inhibition of the slave nodes is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device, a storage medium, and a terminal for determining transmission power of a multi-node repeater. Background technique [0002] In the field of mobile communication, a repeater is a device used to expand the coverage of mobile signals. In order to further expand the signal coverage, or enhance the signal coverage in a specific area, multi-node repeaters came into being. Specifically, the multi-node repeater refers to a system that adopts one master node and hangs multiple slave nodes below it in a wired or wireless manner. [0003] When the required signal coverage area is relatively large, or there are multiple slave nodes attached to a master node, and the distance between each slave node and the master node is relatively large, the path loss from each slave node to the master node is different, and there will be mutual The problem of suppressi...
