Description
Technical field
Set the present invention relates to wireless communication technology field, more particularly to a kind of SRS interference coordination method, device and base station
It is standby.
Background technology
With the development of mobile communication technology, user further improves to the demand of communication bandwidth and communication quality, in order to
Adapt to the demand of the broadband and IPization of radio communication, third generation partner program (3GPP, The 3rd Generation
Partnership Project) go to be grouped at high speeds and access (HSDPA, High Speed Downlink Packet
Access), High Speed Uplink Packet access (HSUPA, high speed uplink packet access), enhanced height
On the basis of the technologies such as fast packet access technique (HSPA+), it is proposed that 3G Long Term Evolution (LTE, Long Term
Evolution) technology provides the user with higher message transmission rate, bigger power system capacity and lower time delay.
LTE supports two kinds of frame structures on interface in the air：Frame format 1 and frame format 2, and corresponding FDD
(FDD, Frequency Division Duplexing) and two kinds of time division duplex (TDD, Time Division Duplexing)
Duplex mode.In fdd, a length is divided into 10 identical subframes by 3GPP for 10ms radio frames
(subframe), each subframe is made up of two length for 0.5ms time slot (slot)；In TDD, radio frames are then long by two
Spend field (Half Frame) composition for 5ms, each field is made up of 5 length for 1ms subframe, wherein have preceding field by
4 common subframes and 1 special subframe composition, rear field may be identical with preceding field, it is also possible to only including 5 common subframes
There is no special subframe.Common subframe is made up of two 0.5ms time slot, and special subframe is divided into 3 special time slots：During ascending pilot frequency
Gap (UpPTS, Uplink Pilot Time Slot), protection time slot (GP, Guard Period) and descending pilot frequency time slot
(DwPTS, Downlink Pilot Time Slot).TDD frame structure is as shown in Figure 1.
Estimating for up channel is carried out using detection reference signal (SRS, Sound Reference Signal) in LTE system
Meter, is referred to as Sounding reference signals by SRS signal below.Sounding reference signals can be divided into broadband spy to channel detection
Two kinds of survey pattern (broadband Sounding) and arrowband detection mode (arrowband Sounding)：Broadband Sounding can carry out full range
The channel detection of band, without frequency hopping, is adapted to quality preferably, more stable channel；Arrowband Sounding is also known as frequency-hopping mode, often
The narrower channel of secondary frequency band of detection, transmission data will be adjusted according to current channel quality information by completing next time slot after detection
Required resource.
The transmission position of Sounding reference signals, occupied bandwidth, transmission cycle can be configured by base station, be set by base station
Sounding reference signals occupied bandwidth and the cycle is sent, and dispatch and be transmitted on UE some running time-frequency resource.Wherein：

Orthogonal Frequency Division Multiplexing) transmit on symbol, can also be on UpPTS 1 or 2
Transmitted in individual OFDM symbol；Sounding reference signals send the cycle：2ms, 5ms, 10ms, 20ms, 40ms, 80ms are supported,
In eight kinds of cycles of 160ms, 320ms, in FDD system, the most short cycle is 2ms, in a tdd system, and 5ms is at most sent twice, such as
During uplink and downlink timeslot proportioning 2: 2, Sounding reference signals are at most sent on UpPTS and on last sub-frame of uplink respectively
Once；Sounding reference signal occupied bandwidths：Sounding reference signals maximum can take 96 resource blocks (RB,
Resource Block), minimum takes 4RB, and 2 parameters take to describe Sounding reference signals defined in 3GPP agreements
Bandwidth：The exclusive parameter of cell (Csrs, Cell-Specific SRS) and terminal exclusive parameter (Bsrs, UE-Specific
SRS).Under every kind of system bandwidth configuration, Csrs has 8 kinds of values, and Bsrs has 4 kinds of values.As shown in Fig. 2 under 10MHz bandwidth,
During Csrs=0, the Sounding reference signal occupied bandwidth schematic diagrames of 4 kinds of difference Bsrs values, Sounding reference signals are accounted for
It is in the mode successively decreased step by step with bandwidth.
In existing LTE system, the configuration of Sounding reference signals can be multiple in base station scheduling, same cell
Multiple users to share identical running time-frequency resources between user and different districts, when number of users increases, Sounding is with reference to letter
Number collision probability occurred increase, causes Sounding reference signal-to-interferences between user, and then influence estimating for base station up channel
Meter, so as to reduce cell uplink handling capacity.

As shown in figure 4, the implementation process diagram to implement SRS interference coordination method in one, comprises the following steps：
S401, the cluster that Sounding reference signal resources are divided into predetermined number；
When it is implemented, Sounding reference signal resources are divided into N clusters first, it is preferred that N >=3.
Specifically, the principle of sub-clustering is as follows：
Step 1: determining the quantity of cluster of the Sounding reference signals in time-domain resource and frequency domain resource respectively；
First, the quantity of cluster of the Sounding reference signals in time-domain resource is determined
It is preferred that the quantity for the cluster for determining Sounding reference signals in time-domain resource can be matched according to system time gap

Assuming that cell needs to support 24 users simultaneously, then at most need to support 24/4=6 Sounding ginseng in same time domain resource
Examine signal, if Sounding reference signals when taking minimum bandwidth, it is necessary to take 6*8=48RB so that, when system bandwidth is
Can be 96RB because Sounding reference signals take maximum bandwidth during 20MHz, therefore, can be by frequency domain resource
Sounding reference signal resources are divided into 96/48=2 clusters.
