Description

Cell coordination method and base station

Technical field

The present invention relates to communication technique field, particularly a kind of cell coordination method and base station.

Background technology

At LTE (Long-TermEvolution, Long Term Evolution) in system, in order to realize up frequency domain dispatching, UE (UserEquipment, subscriber equipment) need transmission SRS sequence (SoundingReferenceSignal, detection reference signal) to detect channel.Because multiple subscriber equipment all will send SRS sequence, CDM (CodeDivisionMultiplexing is adopted in LTE, code division multiplexing) the SRS sequence of mode and the multiplexing multiple subscriber equipment of FDM (FrequecyDivisionMultiplexing, frequency division multiplexing) formula.

Under actual networking scene, between neighbor cell, mutual interference may be there is.Particularly in heterogeneous network, low power nodes and micro-base station are placed in macro base station coverage area by cloth, the more micro-base station of macro base station transmitted power is much larger, and become more serious with the interference problem between each base station covered, the upward signal of different districts UE exists severe jamming.

As shown in Figure 1a, left figure is disturbed UE place cell uplink running time-frequency resource schematic diagram, and right figure is interference UE place cell uplink running time-frequency resource schematic diagram.When the UE of interfered cell sends SRS sequence, if UE to be scheduled on identical running time-frequency resource with larger power at PUSCH (PhysicalUplinkSharedChannel in interfered cell, Physical Uplink Shared Channel) send data, then in interfered cell, the SRS sequence of UE will be subject to severe jamming.Serious interference declines making the SRS demodulation performance of interfered cell UE, causes invalid uplink data scheduling and power control, uplink timing offset etc.

As shown in Figure 1 b, left figure is disturbed UE place cell uplink running time-frequency resource schematic diagram, and right figure is interference UE place cell uplink running time-frequency resource schematic diagram.When the UE of interfered cell sends SRS sequence, if UE is scheduled in larger power transmission SRS sequence on identical running time-frequency resource in interfered cell, then in interfered cell, the SRS sequence of UE will be subject to severe jamming.Serious interference declines making the SRS demodulation performance of interfered cell UE, causes invalid uplink data scheduling and power control, uplink timing offset etc.

Equally, as illustrated in figure 1 c, left figure is disturbed UE place cell uplink running time-frequency resource schematic diagram, and right figure is interference UE place cell uplink running time-frequency resource schematic diagram.When the UE of interfered cell sends PUSCH, if UE is scheduled in larger power transmission SRS sequence on identical running time-frequency resource in interfered cell, then in interfered cell, last symbol of the PUSCH signal of UE will be subject to severe jamming.Serious interference has to use the MCS (ModulationandCodingScheme of low order by making the decline of the PUSCH demodulation performance of interfered cell UE, modulation coding mode) mode or more serious situation will cause data transmission fails, and data transmission efficiency is reduced.

By coordinating the SRS sequence that UE uses in community in prior art, ensure to solve minizone SRS sequence and SRS sequence interferes with each other problem in the orthogonality of code domain between the SRS sequence that minizone UE uses.

After analyzing prior art, inventor finds that prior art at least has following shortcoming: cannot solve the interference between UESRS sequence and PUSCH between community, make communication quality low, poor signal quality.
