Description

Method for controlling uplink power of user equipment in heterogeneous network and network equipment

technical field

The present invention relates to the field of wireless communication, in particular to an uplink power control method and network equipment of user equipment in a heterogeneous network.

Background technique

Small cells are deployed on the basis of macro cells (covered by macro base stations) in cellular network topology. A small cell consists of various types of low power nodes (Low Power Node, LPN), such as remote radio head (RemoteRadio Header, RRH), repeater (Relay), signal booster (Repeater), Micro station, Pico station or Femto stations (among them, Micro stations, Pico stations, and Femto stations are collectively referred to as small stations) to achieve short-distance and small-area coverage, and optimize indoor and hotspot scenarios and cell boundaries. These low-power nodes are completely under the coverage of the macro cell, forming another layer of topology above the current cellular topology, forming a hierarchical heterogeneous network (Heterogeneous Network).

In a heterogeneous network environment, user interference becomes complicated. As a means of suppressing interference, an uplink power control method provided by the prior art is: the base station determines the adjustment step size of the uplink power control according to the quality of the received user uplink signal, and adds an adjustment step size to the original uplink power Long means that the uplink power is increased or decreased, thereby controlling the user's uplink power.

Since the basic adjustment steps stipulated in the agreement are only -1dB, 1dB, -4dB, and 4dB, if the uplink power is controlled only according to the basic adjustment steps stipulated in the agreement, sometimes the uplink power will be adjusted too large or too small. If the adjustment range is too large, it will cause interference to other users. If the adjustment range is too small, the quality of the user's signal received by the base station will be poor. For example, suppose two user equipments (User Equipment, UE) in the heterogeneous network, the two UEs are respectively denoted as UE1 and UE2, use the same physical resource block (Physical Resource Block, PBR) to communicate, wherein, UE1 is The edge user of the macro cell, UE2 is a terminal of the small cell, and the signal from the macro base station is enhanced through the low power node of the small cell. Since UE1 is an edge user far away from the macro base station, if the uplink power of UE1 is adjusted too much in order to improve the quality of the received signal, for example, it is adjusted according to the basic adjustment step size of 4dB, it may cause UE1's adjusted The uplink power will cause great interference to UE2's uplink reception.
