The mapping mode of first reference signal.
S216, the receiving terminal determine the Secondary resource according to the described second instruction information.
Transmitting terminal can be directly at least two mapping modes a kind of mapping mode determine Secondary resource, and to connecing
Receiving end sends the second instruction information, the mapping mode of the first reference signal of instruction transmitting terminal selection, for example, when first resource
When position is overlapped with the position of the resource corresponding to the first mapping mode of the first reference signal, transmitting terminal can select second to reflect
Mode is penetrated, and Secondary resource is determined according to the second mapping mode, at this point, the second instruction information indicates the second mapping mode;When
When the position of resource corresponding to first mapping mode of the position of one resource and the first reference signal is misaligned, transmitting terminal can be with
The first mapping mode is selected, and Secondary resource is determined according to the first mapping mode, at this point, second instruction information the first mapping of instruction
Mode.Above-mentioned second instruction information can be DCI or others indicate information, such as RRC signaling.
For another example after transmitting terminal determines the mapping mode of Secondary resource according to offset, can be sent to receiving terminal
Second instruction information, the second instruction information are used to indicate the mapping mode of Secondary resource.
Therefore, the method for transmission of reference signals provided by the embodiments of the present application, transmitting terminal send the second instruction to receiving terminal
Information, receiving terminal directly determine the mapping mode of Secondary resource according to the second instruction information.
Optionally, the first resource is used for transmission the reference signal of LTE system and the reference signal packet of the LTE system
Include CRS.
When communication system configuration first resource, first resource can be used for transmitting the reference signal of LTE system, the LTE

Fig. 5 A show a kind of schematic diagram of the method for determining Secondary resource.Fig. 5 A and it is following each shown in figure when
Frequency resource is by taking the 15kHz subcarrier spacings of normal cyclic prefix as an example.If (numerology refers to wrap other parameters
Include { subcarrier spacing, cyclic prefix, frame/subframe/time slot/mini-slot (mini-slot)/symbol, bandwidth } set or its
In subset), relationship between different numerology can with and so on.Pattern shown in Fig. 5 A represents that a subframe is wrapped
The running time-frequency resource included, on frequency domain by taking 12 subcarriers as an example, wherein, each lattice represents to occupy symbol, a frequency in time domain
The RE of a subcarrier is occupied on domain, does not have the few time-frequency money that reference signal is distributed in tagged light gray RE expressions in Fig. 5 A
Source, the RE in bold box represent reserved resource (that is, first resource), due to reserving resource and distributing to the part RE of reference signal
It overlaps, therefore, it is necessary to redefine the mapping position of reference signal.Optionally, as shown by arrows in FIG., according to reserved resource
The RE that location determination is located at the symbol of i=4 in even timeslots is used for transmission reference signal, so as to when being used for transmission reference signal
RE be reserved resource occupation after, reference signal can be transmitted by other RE, and the position of reference signal transmission is at this time
It is identified as R0RE.
Fig. 5 B show the schematic diagram of the method for another determining Secondary resource.Pattern shown in Fig. 5 B represents a subframe
Included running time-frequency resource, wherein, each lattice represents to occupy a symbol in time domain, subcarrier is occupied on frequency domain
Do not have the portion of time frequency resources that reference signal is distributed in tagged light gray RE expression in RE, Fig. 5 B, the RE in bold box is represented
Reserved resource (that is, first resource), since reserved resource partially overlaps with distributing to the RE of reference signal, therefore, it is necessary to again
Determine the mapping position of reference signal.Optionally, as shown by arrows in FIG., it is located at k=7's according to the location determination of reserved resource
The RE of subcarrier is used for transmission reference signal, so as to after the RE for being used for transmission reference signal is reserved resource occupation, with reference to letter
It number can be transmitted by other RE, the position of reference signal transmission is is identified as R at this time0RE.
Method shown in Fig. 5 A and Fig. 5 B is merely illustrative of, and offset can also be that the symbol of other quantity or son carry
Wave, such as the offset method shown in Fig. 5 C do not have the portion of time frequency resources that reference signal is distributed in tagged light gray RE expressions,
RE in bold box represents reserved resource, wherein, reserved resource occupies two symbols, then offset can be two symbols, scheme
Arrow represents to determine to be used for transmission the resource of reference signal according to the position and offset of reserved resource in 5C, at this time reference signal
The position of transmission is is identified as R0RE;Offset method as shown in Figure 5 D again does not have tagged grey RE expressions to distribute to ginseng
The portion of time frequency resources of signal is examined, the RE for distributing to reference signal occupies two symbols, and the RE in bold box represents reserved resource,
Reserved resource is overlapped with distributing to the resource of reference signal, it may be determined that offset is two symbols.Arrow represents root in Fig. 5 D
Determine to be used for transmission the resource of reference signal according to the position and offset of reserved resource, the position of reference signal transmission is mark at this time
Know for R7RE.RE so as to avoid transmission of reference signals is overlapped with the occupied RE of reserved resource.
In addition, in the method for determining Secondary resource shown in Fig. 5 A to Fig. 5 D, can also determine to be used for from reserved resource
The Secondary resource of transmission of reference signals.
Fig. 6 shows that another determines the schematic diagram of the method for Secondary resource.As shown in fig. 6, first antenna sends first
RS, the running time-frequency resource for distributing to the first RS is the RE of grey (without grid), and the second antenna emits the 2nd RS, distributes to the 2nd RS
Running time-frequency resource be grey (with grid) RE, the RE in bold box is reserved resource, since reserved resource is with being used for transmission the
The RE of one RS is overlapped, it is therefore desirable to be redefined the RE for being used for transmission the first RS, determined to be reassigned to the according to offset
During the RE of one RS, since the RE (that is, information resources) having on the character position of i=4 is already allocated to the 2nd RS, offset
Amount cannot be equal to 4 symbols, that is, transmitting terminal is needed according to reserving resource in position of the first resource in running time-frequency resource and the
Location determination offset of three resources in system time frequency resource.Arrow is represented according to R in Fig. 61Position and offset it is true
Fixed first RS transmits the position of the first RS to be identified as R at this time0RE.Above-described embodiment is merely illustrative of, and the application is implemented
