Description
Technical field
The present invention relates to the communications field, the transmission of particularly a kind of SRS and cycle CSI and indicating means thereof, Apparatus and system.
Background technology
Advanced Long Term Evolution (Long Term Evolution-Advanced LTE-Advanced) in the system, is called for short the LTE-A system, is to support the system bandwidth wideer than LTE system, like 100MHz, normally adopts following two kinds of spectrum allocation may modes:
A kind of is to adopt the mode of single-frequency spectral directly to distribute the frequency spectrum of 100M bandwidth, specifically as shown in Figure 1.
Another kind is the mode that adopts spectrum aggregating, becomes 100M bandwidth confession system to use the spectrum aggregating of distributing to existing system, and is specifically as shown in Figure 2.Consult shown in Figure 2ly, when adopting the spectrum aggregating mode, the up-downgoing carrier wave can asymmetricly dispose in the LTE-A system, and promptly user terminal can take N >=1 carrier wave and carries out downlink transfer, takies M >=1 carrier wave and carries out uplink.
At present; Formulated following scheme among the agreement Rel-8 of the LTE system that standardization effort has been accomplished basically; Ascending control information (Uplink Control Information; UCI) can on Physical Uplink Control Channel (PUCCH), transmit, also can be in Physical Uplink Shared Channel (PUSCH) and data multiplex transmission.So-called UCI information comprises channel condition information (CSI), dispatch request information (SR) and response message (ACK/NACK), and wherein, CSI comprises channel quality quality (CQI), pre-coding matrix index (PMI) and order indication (RI) again.
In the practical application, aperiodic the reporting in PUSCH and transmit of CSI, the CQI solicited message (CQI request) through 1bit in the uplink scheduling signaling (UL grant) triggers.Cycle CSI newspaper then transmits in PUCCH according to pre-configured report cycle, and adoptable channel format is any one among PUCCHformat 2, PUCCH format 2a and the PUCCH format 2b.
In addition; In order to make the base station in time obtain the channel conditions of up-link carrier; In a sub-frame of uplink, also possibly exist periodic spy reference signal (Sounding Reference Symbol, SRS), parameters such as the cycle of SRS transmission and bandwidth are that UE is exclusive; And by the semi-static configuration in base station, SRS can only send on last symbol of the sub-frame of uplink that has disposed the SRS transmission.For the ease of describing, the sub-frame of uplink that below will dispose the SRS transmission abbreviates the SRS of system subframe as.
On PUSCH, the CSI of feedback, ACK/NACK information, SR and SRS can be in same sub-frame of uplink transmission simultaneously, last symbol of PUSCH is reserved and is used for transmitting SRS, data message according to SRS transmission carry out rate-matched.
On PUCCH, whether support SRS, can pass through the semi-static configuration of parameter ackNackSRS-SimultaneousTransimission with ACK/NACK and/or SR transmission simultaneously in same sub-frame of uplink.If this parameter is False, then when the PUCCH of transferring ACK/NACK and/or SR and SRS need transmit in same subframe, SRS will be dropped, and UE at PUCCH feeding back ACK/NACK and/or SR.If this parameter is True; SRS then; Can in a sub-frame, transmit simultaneously with the PUCCH of loading ACK/NACK and/or SR, adoptable channel format can be any one among shortened PUCCH format 1, shortened PUCCH format 1a and the shortened PUCCH format 1b; So-called shortened PUCCH i.e. not transferring ACK/NACK and/or SR on the symbol of last in sub-frame of uplink, and SRS will transmit (this SRS information possibly be the SRS information of any UE) according to predetermined configuration on this symbol.
In the agreement Rel-8 of LTE system, stipulate, do not support that the cycle CSI on SRS and the PUCCH transmits simultaneously, when there is the cycle CSI on the PUCCH to be feedback simultaneously in UE in the SRS of system subframe, the SRS transmission will be dropped, and UE is only at PUCCH report cycle CSI.
And for the LTE-A system; Can support at most that at present 5 carrier waves carry out polymerization, promptly in same sub-frame of uplink, for the ease of descending scheduling; UE will feed back the cycle CSI of corresponding a plurality of descending carriers in a sub-frame of uplink; The feedback quantity of CSI is bigger, and the CSI of a plurality of descending carriers can dispose different feedback cycles respectively, thereby has increased the feedback density of cycle CSI; Like this, on PUCCH, the collision probability that cycle CSI and SRS feed back in same sub-frame of uplink is bigger; If the LTE-A system still continues to use the SRS feedback mechanism of LTE system; So, the probability that SRS is dropped is bigger, like this; The base station can't in time obtain the channel conditions of up-link carrier, thereby influence the accuracy of uplink scheduling.
In view of this, need to be directed against the feedback mechanism that SRS is decided in the recasting of LTE-A system, to overcome above-mentioned defective.

In the practical application, when execution in step 510, the configuration information of confirming can be sent to UE through high-level signaling in the base station, also can pass through Physical Downlink Control Channel (PDCCH) signaling and send the configuration information of confirming to UE; Wherein, The base station is configuration information (Cell specific) or other configuration information of UE level (UE specific) of cell level through the configuration information that high-level signaling sends; And the high-level signaling that adopt the base station can be layer 3 (L3) and layer 2 (L2) signaling, as, Radio Resource control (RRC) signaling.
On the other hand, when execution in step 510, UE can be indicated in the base station; If the configuration information according to receiving is confirmed transmitting SRS; Then on last symbol in having the sub-frame of uplink of SRS transmission, according to the preset configuration transmitting SRS of SRS, and transmission cycle CSI in this sub-frame of uplink not; If the configuration information according to receiving is confirmed transmission cycle CSI, then in the sub-frame of uplink that has the SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this up son not; Wherein, Base station indication UE; During through PUCCH transmission cycle CSI; The PUCCH channel format that adopts can be any one (the consulting shown in Figure 6) among PUCCH format 2, PUCCH format 2a and the PUCCH format 2b, also can be the channel format (consulting shown in Figure 7) based on the OFDM (DFT-S-OFDM) of DFT expansion.
For example, the base station adopts high-level signaling to send configuration information to UE, when UE is carried out semi-static configuration, can in high-level signaling, adopt the different conditions of A bit information to represent the corresponding operating that UE should carry out.
More excellent, A=1.The base station can be provided with: when the value of A bit data was " 0 ", expression indication UE transmitting SRS was promptly on last symbol in the sub-frame of uplink that has the SRS transmission; According to the preset configuration transmitting SRS of SRS, and transmission cycle CSI in this sub-frame of uplink not, when the value of A bit data is " 1 "; Expression indication UE transmission cycle CSI; Promptly in having the sub-frame of uplink of SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this up son not; Certainly, the base station also can be provided with, when the value of A bit data is " 1 "; Expression indication UE transmitting SRS is promptly on last symbol in the sub-frame of uplink that has the SRS transmission, according to the preset configuration transmitting SRS of SRS; And transmission cycle CSI in this sub-frame of uplink not, when the value of A bit data is " 0 ", expression indication UE transmission cycle CSI; Promptly in having the sub-frame of uplink of SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this up son not.
Again for example, the base station adopts the PDCCH signaling to send configuration information to UE, and UE is carried out dynamic-configuration when dynamic, can in the DCI information field in the PDCCH signaling, adopt the different conditions of B bit information to represent the corresponding operating that UE should carry out.
More excellent, B=1.The base station can be provided with: when the value of B bit data was " 0 ", expression indication UE transmitting SRS was promptly on last symbol in the sub-frame of uplink that has the SRS transmission; According to the preset configuration transmitting SRS of SRS, and transmission cycle CSI in this sub-frame of uplink not, when the value of B bit data is " 1 "; Expression indication UE transmission cycle CSI; Promptly in having the sub-frame of uplink of SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this up son not; Certainly, the base station also can be provided with, when the value of B bit data is " 1 "; Expression indication UE transmitting SRS is promptly on last symbol in the sub-frame of uplink that has the SRS transmission, according to the preset configuration transmitting SRS of SRS; And transmission cycle CSI in this sub-frame of uplink not, when the value of B bit data is " 0 ", expression indication UE transmission cycle CSI; Promptly in having the sub-frame of uplink of SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this up son not.
Based on the foregoing description, to consult shown in Figure 7ly, in the embodiment of the invention, the detailed process of UE transmitting SRS and cycle CSI is following:
Step 800:UE receives the configuration information that send the base station, and this configuration information is used for disposing this UE at the sub-frame of uplink transmitting SRS or the transmission cycle CSI that have the SRS transmission.
In the practical application, the UE station can receive the configuration information that send the base station through high-level signaling, also can receive the configuration information that send the base station through the PDCCH signaling; Wherein, UE is configuration information (Cell specific) or other configuration information of UE level (UEspecific) of cell level through the configuration information that high-level signaling receives; And high-level signaling can be layer 3 (L3) and layer 2 (L2) signaling, as, Radio Resource control (RRC) signaling.
Step 810:UE is according to the configuration information that receives, in the sub-frame of uplink that has the SRS transmission, and transmitting SRS or transmission cycle CSI.
In the practical application, when execution in step 810, UE is if confirm transmitting SRS according to the configuration information that receives; Then on last symbol in having the sub-frame of uplink of SRS transmission, according to the preset configuration transmitting SRS of SRS, and transmission cycle CSI in this sub-frame of uplink not; UE is if confirm transmission cycle CSI according to the configuration information that receives; Then in having the sub-frame of uplink of SRS transmission, through PUCCH transmission cycle CSI, and transmitting SRS in this sub-frame of uplink not; When UE passes through PUCCH transmission cycle CSI; The PUCCH channel format that adopts can be any one (the consulting shown in Figure 6) among PUCCH format 2, PUCCH format 2a and the PUCCHformat 2b, also can be the channel format (consulting shown in Figure 7) based on DFT-S-OFDM.
For example; The base station adopts 1bit to carry configuration information in the RRC signaling; Perhaps, extra increase 1bit carries configuration information in the PDCCH signaling of bearing downlink mandate indication (DL grant), and indication UE is when existing the cycle CSI that passes through the PUCCH transmission in the sub-frame of uplink that has the SRS transmission simultaneously; According to this configuration information transmitting SRS or transmission cycle CSI; With " 0 " expression indication UE transmitting SRS, through PUCCH transmission cycle CSI, above-mentioned RRC signaling is configured to other configuration information of UE level with " 1 " expression indication UE.So; After current UE receives above-mentioned RRC signaling or carries the PDCCH signaling of DL grant, be " 0 ", then be informed in the sub-frame of uplink that has the SRS transmission if detect above-mentioned 1bit configuration information; If there is the cycle CSI that needs through the PUCCH transmission simultaneously; Then abandon this cycle CSI, and according to the preset configuration of SRS, transmitting SRS on last symbol in above-mentioned sub-frame of uplink; In like manner; After UE receives above-mentioned RRC signaling or carries the PDCCH signaling of DL grant, be " 1 ", then be informed in the sub-frame of uplink that has the SRS transmission if detect above-mentioned 1bit configuration information; If there is the cycle CSI that needs through the PUCCH transmission simultaneously; Then abandon this SRS, and, adopt Fig. 6 or PUCCH channel format transmission cycle CSI shown in Figure 7 at this sub-frame of uplink.
