Embodiment
Embodiment of the present invention technical scheme main realized principle, embodiment and the beneficial effect that should be able to reach is at length set forth below in conjunction with each accompanying drawing.
As shown in Figure 1, in the embodiment of the present invention, SRS sending method flow chart, its concrete processing procedure is as follows:
In the LTE-A system, terminal exists a plurality of SRS ports to send simultaneously SRS to the base station, and at this moment, a plurality of SRS ports take identical time-domain resource, carries out yard territory resource multiplex or carry out frequency domain resource by different Comb information multiplexing by different CS information.
For CS information and the Comb information of indicating terminal to each SRS port is configured, the base station can be at high-level signaling or Physical Downlink Control Channel (PDCCH, Physical Downlink ControlChannel) carry SRS configuration indication information in signaling, carry the CS configuration indication information of 3 bits and the Comb configuration indication information of 1 bit in SRS configuration indication information, terminal is determined CS information and the Comb information of each SRS port by these configuration indication informations.
Wherein according to CS configuration indication information determine each SRS port CS information can but be not limited to comprise following three kinds of execution modes, be respectively:
the first execution mode, set in advance the corresponding relation of SRS port number and CS spacing, after receiving SRS configuration indication information, terminal is according to the CS configuration indication information that comprises in SRS configuration indication information, determine the CS information of first SRS port, the CS that is about to comprise in SRS configuration indication information configures indication information as the CS information of first SRS port, then according to the quantity of SRS port, in the corresponding relation of SRS port number and CS spacing, determine the CS spacing between the SRS port, again according to the CS information of first SRS port and the CS spacing between the SRS port, determine the CS information of other SRS ports,
For example, the corresponding relation of default SRS port number and CS spacing is: 2 CS spacings corresponding to SRS port are 4,4 CS spacings corresponding to SRS port are 2, the CS configuration indication information that comprises in the SRS configuration indication information that terminal receives is 0, terminal is defined as 0 with the CS information of first SRS port, if the quantity of SRS port is 1, the CS information of this SRS port is 0; If the quantity of SRS port is 2, according to the corresponding relation of default SRS port number and CS spacing as can be known, the spacing between the CS information of first SRS port and the CS information of second SRS port is 4, so the CS information of second SRS port should be 4; If the quantity of SRS port is 4, according to the corresponding relation of default SRS port number and CS spacing as can be known, spacing between the CS information of the spacing between the CS information of the spacing between the CS information of first SRS port and the CS information of second SRS port, the CS information of second SRS port and the 3rd SRS port and the CS information of the 3rd SRS port and the 4th SRS port is 2, therefore the CS information of second SRS port should be 2, the CS information that the CS information of the 3rd SRS port should be 4, the four SRS ports should be 6.
the second execution mode, after receiving SRS configuration indication information, terminal is according to the CS configuration indication information that comprises in SRS configuration indication information, determine the CS information of first SRS port, the CS that is about to comprise in SRS configuration indication information configures indication information as the CS information of first SRS port, then determine CS spacing between the SRS port by other indication informations, again according to the CS information of first SRS port and the CS spacing of determining, determine the CS information of other SRS ports, wherein the base station can arrange the CS spacing for terminal separately, the base station will send to terminal for the CS spacing of terminal setting separately by PDCCH signaling or high-level signaling this moment, also identical CS spacing can be set for all terminals in the residential quarter in addition, this moment, terminal can be determined CS spacing between the SRS port by the CS spacing configuration information of affiliated subdistrict,
For example, the CS configuration indication information that comprises in the SRS configuration indication information that terminal receives is 0, terminal is defined as 0 with the CS information of first SRS port, the CS spacing that terminal is determined between adjacent SRS port by other indication informations is 2, and the quantity of SRS port is 2, and the CS information of second SRS port should be 2.
The third execution mode, after receiving SRS configuration indication information, terminal configures with SRS the CS index information that the CS configuration indication information that comprises in indication information is defined as each SRS port, then according to the CS index information of determining, in corresponding relation between the CS of CS index information and each transmit port information, search the CS information of each SRS port.
For example, set up in advance the corresponding relation between the CS information of CS index information and each transmit port, this corresponding relation can but be not limited to as shown in table 1 or table 2, wherein can based on maximizing the principle of the CS spacing between each SRS port under the prerequisite that guarantees nested structure, set up above-mentioned corresponding relation.If the CS configuration indication information that comprises in the SRS that terminal receives configuration indication information is 4, and the quantity of SRS port is 4, the above-mentioned corresponding relation of setting up is as shown in table 1, terminal is by tabling look-up 1 as can be known, the CS information of first SRS port (port 0) is 4, the CS information of second SRS port (port one) is that the CS information of 0, the three SRS port (port 2) is that the CS information of 6, the four SRS ports (port 3) is 2; If the above-mentioned corresponding relation that terminal is set up is as shown in table 2, terminal is by tabling look-up 2 as can be known, the CS information of first SRS port (port 0) is 4, the CS information of second SRS port (port one) is 0, the CS information of the 3rd SRS port (port 2) is 2,, the CS information of the 4th SRS port (port 3) is 6.
