Description

The ascending power control method of subscriber equipment and the network equipment in the heterogeneous network

Technical field

The present invention relates to wireless communication field, relate in particular to ascending power control method and the network equipment of subscriber equipment in the heterogeneous network.

Background technology

The basic deploy small-cell of macrocell (being covered by macro base station) in the cellular network topology.Small-cell is by various types of low power nodes (Low Power Node, LPN), for example, far end radio frequency head (Remote Radio Header, RRH), repeater (Relay), Signal Booster (Repeater), Micro station, Pico station or Femto station are (wherein, Micro station, Pico station and Femto station are referred to as the small station) etc. covering, realize the covering of short distance small size, be optimized with focus scene and cell boarder indoor.These low power nodes are under the covering of macrocell fully, form the topology of another layer on present cellular topology, have consisted of the heterogeneous network (Heterogeneous Network) of layering.

In heterogeneous network environment, user's interference complicated.As a kind of means that suppress to disturb, a kind of ascending power control method that prior art provides is: the adjustment step-length of uplink power control is determined in the base station according to the quality of the user uplink signal that receives, increase by one at original ascending power and adjust step-length, mean that ascending power increases or reduces, thus control user's ascending power.

Because the basic adjustment step-length of stipulating in the agreement only has-1dB, 1dB ,-several granularities such as 4dB and 4dB, if just control ascending power according to the basic adjustment step-length of stipulating in the agreement, sometimes ascending power is adjusted too much or too small.Excessive when adjusting range, will cause the interference to other users, if adjusting range is too small, the quality of this subscriber signal that the base station receives is relatively poor again.For example, suppose two subscriber equipment (User Equipment in the heterogeneous network, UE), these two UE are designated as respectively UE1 and UE2, use identical Physical Resource Block (Physical Resource Block, PBR) to communicate, wherein, UE1 is the edge customer of macrocell, and UE2 is the terminal of small-cell, and the low power nodes by small-cell strengthens the signal from macro base station.Because UE1 is from the edge customer of macro base station away from, therefore, if improve to receive the quality of signal and adjust the ascending power of UE1 excessive, for example, basic adjustment step-length according to 4dB is adjusted, and then may cause the ascending power after UE1 adjusts can cause to the uplink receiving of UE2 very large interference.

Summary of the invention

The embodiment of the invention provides ascending power control method and the network equipment of subscriber equipment in the heterogeneous network, reduce this heterogeneous network during with the ascending power of certain subscriber equipment in adjusting heterogeneous network in the interference of other subscriber equipmenies.
