Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of state of carrier aggregation and issue the method and apparatus of serving capable measuring reference signals.
Background technology
(Sounding Reference Signal is to be used for measuring radio channel information (channel state information, signal CSI) between a kind of terminal equipment and base station SRS) to measuring reference signals.(Long Term Evolution, LTE) in the system, (User Equipment is UE) according to base station (e-node-B, eNB) Zhi Shi bandwidth, frequency domain position, parameters such as cycle and sub-frame offset, timed sending uplink SRS for subscriber equipment at Long Term Evolution.ENB judges the up CSI of UE according to the SRS signal that receives, and carries out operations such as frequency domain selection scheduling, closed-loop power control according to the CSI that obtains.
In the LTE system, the SRS signal that UE sends is by to YITIAOGEN sequence r
U, v(n) carrying out cyclic shift α obtains.Just can access different SRS sequences to carry out different cyclic shift α with the YITIAOGEN sequence, and mutually orthogonal between these SRS sequences that obtain, so can use to different UE these SRS sequence allocation.In LTE, the SRS sequence definition 8 cyclic shifts, be respectively: 0,1,2,3,4,5,6,7, with the indication of 3bit signaling.That is to say that under same running time-frequency resource, the UE in the sub-district has 8 available sign indicating number resources, eNB can dispose 8 UE at most and send SRS simultaneously.
In the LTE system, SRS signal frequency-domain bandwidth adopts tree to prepare.The corresponding tree of each SRS bandwidth preparation (being SRS bandwidth configuration), the maximum bandwidth (or being called the SRS bandwidth range) of this SRS bandwidth preparation that top SRS bandwidth (SRS-Bandwidth) is corresponding.Table 1~table 4 has provided the SRS bandwidth preparation in the different upstream bandwidth scopes.With SRS bandwidth preparation 1 in the table is example, and b=0 is 0 layer, is the top of tree, and the pairing SRS bandwidth of this one deck is that (Resource Block, RB) pairing bandwidth are the maximum SRS bandwidth of this SRS bandwidth preparation to 32 Resource Block; B=1 is 1 layer, and this one deck SRS bandwidth is the bandwidth of 16 RB correspondences, and a SRS bandwidth of last layer splits into 21 layer SRS bandwidth; B=2 is 2 layers, and this one deck SRS bandwidth is the bandwidth of 8 RB correspondences, and a SRS bandwidth of last layer splits into 22 layers SRS bandwidth; B=3 is 3 layers, and the SRS bandwidth of this one deck is the bandwidth of 4 RB correspondences, and a SRS bandwidth of last layer splits into 23 layers SRS bandwidth, and its structure as shown in Figure 1.
In addition, the subcarrier of SRS signal is to place at interval in same SRS frequency band, that is to say, pectinate texture is adopted in the transmission of SRS, and wherein the number of frequency comb (frequency comb) is 2.As shown in Figure 2, when each UE sends SRS, only use one (comb=0 or comb=1) in two frequency comb, only use the frequency domain index to send SRS as the subcarrier (sub-carrier) of even number or odd number corresponding to UE.This pectinate texture allows more user to send the SRS signal in same SRS bandwidth.
In the LTE system, the base station at first is that all UE in the sub-district distribute a SRS bandwidth formulatory indices C
SRS, according to the current pairing RB number of up-link bandwidth (N
RB UL) can determine which table in use table 1~table 4, and then according to C
SRSJust can determine the SRS bandwidth preparation that current area is used.For certain UE, a SRS bandwidth index B also can be distributed for it in the base station
SRSThe index of place layer (or be called).According to preparation of the SRS bandwidth in the sub-district and bandwidth index B
SRS, UE just can obtain the SRS bandwidth that it uses.For example, current area SRS bandwidth formulatory indices C
SRS=1,
Then the SRS bandwidth of current area is formulated as the row of second in the table 2.If current area is 1 for the bandwidth index that certain UE distributes, then the SRS bandwidth of this UE accounts for 16 RB, and the position of the SRS bandwidth of this UE (being the scope of maximum SRS bandwidth, is 48 RB) in the scope of SRS bandwidth.
After UE obtains the SRS bandwidth of oneself, the top signaling n that will send according to eNB
RRCDetermine that oneself sends the initial position of SRS.As shown in Figure 3, different n have been distributed
RRCThe UE of signaling will send SRS in the zones of different of sub-district SRS bandwidth.
When having disposed the frequency hopping of UE, the UE different frequency bands in the SRS of system bandwidth in time sends SRS.When frequency hopping, the base station can be with signaling b
HopThe frequency hopping bandwidth of notice UE.UE frequency hopping mode is the different branches according to SRS bandwidth tree structure, and zones different in the frequency hopping bandwidth send SRS.With the system SRS band width configuration shown in Fig. 1 is example, supposes the band width configuration index B that UE is proprietary
SRS=3, then the bandwidth of UE transmission SRS is 4 RB.The original position of supposing UE transmission SRS again is n
RRC=0 frequency domain position.So, as shown in Figure 4, the base station can be by the different b of configuration
HopWith the different frequency hopping bandwidth of indication UE.

Table 4
In LTE, on time domain, only multiplexing (SingleCarrier Frequency Division Multiple Access SC-FDMA) sends SRS to UE on the symbol at last single carrier frequency division of subframe.UE sends configuration and four relating to parameters of SRS in time domain: the cycle (T of cell-specific (cell-specific)
SFC) and sub-frame offset (Δ
SFC), and the cycle (T of UE special use (UE-specific)
SRS) and sub-frame offset (T
Offset).Table 5,6 provided respectively Frequency Division Duplexing (FDD) (Frequency Division Duplex, FDD) and time division duplex (Time Division Duplex, TDD) cycle of cell-specific and sub-frame offset in the system.The cycle of cell-specific and sub-frame offset have provided the time domain subframe position that all UE in the sub-district may send SRS, and on other subframes, the use of last SC-FDMA symbol and the transmission of SRS are irrelevant.With srsSubframeConfiguration=7 in the table 5 is example, T
SFC=5, Δ
SFC=0, and 1}, as Fig. 5, on behalf of the base station, S in this sub-frame configuration the SRS resource is arranged among the figure, and then cell-specific SRS transmission cycle is 5 subframes in the sub-district, and subframe 0 and subframe 1 position in each cycle can be used for sending SRS by UE.
