Description
Technical field
The present invention relates to the communications field, especially relate to a kind of measuring reference signals (Sounding Reference
Signal, SRS) the collocation method of multiple antennas parameter and device.
Background technology
The uplink physical channel of Long Term Evolution (Long Term Evolution, LTE) system comprises physics Stochastic accessing letter
Road (Physical Random Access Channel, PRACH), Physical Uplink Shared Channel (Physical Uplink
Shared Channel, PUSCH), Physical Uplink Control Channel (Physical Uplink Control Channel,
PUCCH).In LTE, Physical Downlink Control Channel (Physical Downlink Shared Channel, PDCCH) is used for holding
Carry uplink and downlink schedule information, and uplink power control information.(e-Node-B, eNB) can pass through Downlink Control Information in base station
Configurating terminal device (User Equipment, UE), or the configuration of terminal unit acceptance high-rise (higher layers), also
It is referred to as configuring UE by high-level signaling.Downlink Control Information (Downlink Control Information, DCI) form
(format) be divided into DCI format 0,1,1A, 1B, 1C, 1D, 2,2A, 3,3A etc..
SRS is for measuring radio channel information (Channel State between a kind of terminal unit and base station
Information, CSI) signal.In long evolving system, bandwidth that UE indicates according to eNB, frequency domain position, sequence loops
The parameters such as displacement, cycle and sub-frame offset, timing sends uplink SRS on last data symbol sending subframe.ENB root
Judge the up CSI of UE according to the SRS received, and carry out the behaviour such as frequency domain selection scheduling, close-loop power control according to the CSI obtained
Make.
In LTE system, the SRS sequence that UE sends is by Glycine tomentella sequenceIt is circulated displacement in time domain
α obtains.Same root sequence is carried out different cyclic shifts α, it becomes possible to obtain different SRS sequences, and obtain
Between these SRS sequences mutually orthogonal, therefore, it can to distribute to these SRS sequences different UE and use, to realize between UE
CDMA.In LTE system, 8 cyclic shifts α of SRS sequence definition, be given by equation below (1):
Wherein,Indicated by the signaling of 3bit, respectively 0,1,2,3,4,5,6 and 7.It is to say, with for the moment
Frequently under resource, the UE in community has 8 available code resources, and it is same on identical running time-frequency resource that eNB at most can configure 8 UE
Time send SRS.Formula (1) is considered as in time domain, SRS sequence is divided into 8 parts at equal intervals, but owing to SRS sequence length is 12
Multiple, so the minimum length of SRS sequence is 24.
In LTE system, the frequency domain bandwidth of SRS uses tree to configure.Each SRS band width configuration (SRS
Bandwidth configuration) a corresponding tree structure, the SRS bandwidth (SRS-of top (or referred to as ground floor)
Bandwidth) to should the maximum SRS bandwidth of SRS band width configuration, or referred to as SRS bandwidth range.UE refers to according to the signaling of base station
Show, after being calculated the SRS bandwidth of self, the top signaling frequency domain position n sent further according to eNBRRCDetermine that self sends
The frequency domain initial position of SRS.Fig. 1 is distribution difference n of prior artRRCUE send SRS frequency domain initial position schematic diagram,
As it is shown in figure 1, be assigned with different nRRCUE by community SRS bandwidth zones of different send SRS, wherein, UE1 is according to nRRC=
0 determines the frequency initial position sending SRS, and UE2 is according to nRRC=3 determine the frequency initial position sending SRS, and UE3 is according to nRRC
=4 determine the frequency initial position sending SRS, and UE4 is according to nRRC=6 determine the frequency initial position sending SRS.
The sequence that SRS is used is selected from demodulation pilot frequency sequence group, when the SRS of UE carries a width of 4 Resource Block
Time (Resource Block, RB), the computer of a length of 2 RB is used to generate the sequence of (Computer Generated, CG);
When the SRS band of UE is wider than 4 RB, use the Zadoff-Chu sequence of corresponding length.
It addition, in same SRS bandwidth, the subcarrier (sub-carrier) of SRS is spaced apart, say, that
The transmission of SRS uses pectinate texture, and the quantity of the frequency comb (frequency comb) in LTE system is 2, also corresponds to time domain
Repeat factor value (RePetition Factor, RPF) be 2.Fig. 2 is the pectinate texture schematic diagram of the SRS of prior art, as
Shown in Fig. 2, when each UE sends SRS, only use in two frequency comb, comb=0 or comb=1.So, UE according to
The frequency comb comb position instruction of the top signaling of 1 bit, the subcarrier only using frequency domain index to be even number or odd number sends
SRS.This pectinate texture allows more UE to send SRS in same SRS bandwidth.
In same SRS bandwidth, multiple UE can use different cyclic shifts in same frequency comb, then passes through
Code division multiplexing sends SRS, it is also possible to two UE, in different frequency comb, send SRS by frequency division multiplexing.For example, exist
In LTE system, in certain SRS bandwidth (4 RB) send SRS UE, it is possible to use cyclic shift have 8, it is possible to use
Frequency comb be 2, a total of 16 resources that can be used to send SRS of UE thus, say, that in this SRS bandwidth,
At most can send 16 SRS simultaneously.Owing to not supporting uplink single user multiple-input and multiple-output (Single in LTE system
User Multiple Input Multiple Output, SU-MI MO), UE can only have an antenna to send in each moment
SRS, so a UE has only to a SRS resource, therefore, in above-mentioned SRS bandwidth, system at most can be with concurrent multiplexing 16
UE。
Senior LTE (LTE-Advanced, LTE-A) system is the evolution system of future generation of LTE system, in up support
SU-MIMO, and 4 antennas at most can be used as up transmitting antenna.It is to say, UE can be many at synchronization
Send SRS on root antenna simultaneously, and eNB needs to estimate the state on every channel according to the SRS received on every antenna.
The research of existing LTE-A proposes: send SRS except retaining LTE original cycle (periodic), in order to
Improve the utilization rate of SRS resource, improve the motility of scheduling of resource, it is also possible to joined by Downlink Control Information or high-level signaling
Put UE aperiodic (aperiodic) and send SRS.Therefore SRS has the triggering type (trigger type) of two kinds, believes based on high level
The triggering type 0 of order is cycle SRS, and Class1 based on DCI format is SRS aperiodic.When configuration UE multiple antennas sends SRS
Time, how to determine the SRS parameter of every antenna, signaling consumption can be saved, can guarantee that again the motility of configuration, be one and wait to solve
Problem certainly.
