Step 202, terminal receives instruction information, is determined in the time-domain symbol where uplink reference signals according to instruction information Whether allow to carry data, and generates uplink signal to be transmitted.
Specifically, since the configuration of the uplink of instruction information instruction may include waveform, the uplink of uplink At least one of in the code rate of the transmission power of transmission, the order of modulation of uplink and uplink, correspondingly, terminal It can be according to the waveform of uplink, the transmission power of uplink, the order of modulation of uplink and the coding of uplink speed In rate at least one of come determine whether allow in the time-domain symbol where uplink reference signals carry data.For example, when described When the order of modulation of uplink is less than the first thresholding, the terminal determines in the time-domain symbol where the uplink reference signals Do not allow to carry data；Alternatively, when the code rate of the uplink is less than the second thresholding, the terminal determines on described Do not allow to carry data in time-domain symbol where row reference signal；Alternatively, the order of modulation when the uplink is less than the When one thresholding and the code rate of the uplink are less than the second thresholding, the terminal determines where the uplink reference signals Time-domain symbol in do not allow carry data；Alternatively, when the transmission power of the uplink is more than third thresholding, the end Do not allow to carry data in time-domain symbol where the determining uplink reference signals in end.First thresholding, the second thresholding and third The value of thresholding can make an appointment, alternatively, can also be to be sent to terminal by the network equipment.
Lower mask body enumerates several possible realization methods：
Mode one：Terminal determines in the time-domain symbol where uplink reference signals whether permit according to the waveform of uplink Perhaps data are carried
In 5G NR systems, uplink can support SC-FDMA waveforms and OFDM waveforms.In the embodiment of the present invention, consider There is lower PAPR compared to OFDM waveforms to SC-FDMA waveforms, therefore, SC-FDMA waveforms are more suitable in low Signal to Interference plus Noise Ratio It is used in the scene (such as covering limitation scene) of (Signal to interference and noise, SINR).In this field Under scape, higher transmission power is generally required, power amplifier is also required to higher efficiency, therefore, if where uplink reference signals Transmission data signal in time-domain symbol may then cause PAPR significantly raised, this is based on, when uplink is configured as OFDM waves When shape, allow to carry data in the time-domain symbol where uplink reference signals, when uplink is configured as SC-FDMA waveforms When, do not allow in the time-domain symbol where uplink reference signals to carry data.
In specific implementation, terminal can be stored with waveform and label (for indicating the time-domain symbol where uplink reference signals In whether allow carry data, for example, label 1 expression allow carry data, label 0 indicate do not allow carry data) correspondence Relation table, as shown in table 1, OFDM waveforms corresponding label 1, SC-FDMA waveforms corresponding label 0；If terminal determines instruction, information refers to The waveform for the uplink shown is OFDM waveforms, then can determine allows to carry number in the time-domain symbol where uplink reference signals According to；If terminal determines that the waveform of the uplink of instruction information instruction is SC-FDMA waveforms, uplink reference signals institute can determine Time-domain symbol in do not allow carry data.

Mode two：Terminal is to determine in the time-domain symbol where uplink reference signals according to the transmission power of uplink It is no to allow to carry data
In the embodiment of the present invention, it is contemplated that PAPR directly affects power amplifier, therefore, according to the transmission power of uplink come really Whether determine allows to carry data in the time-domain symbol where uplink reference signals have stronger feasibility.Terminal can be arranged one Threshold value A, if the transmission power of the uplink of instruction information instruction is more than or equal to threshold value A, terminal can determine uplink with reference to letter Do not allow to carry data in time-domain symbol where number, if the transmission power of the uplink of instruction information instruction is less than threshold value A, Then terminal, which can determine, allows to carry data in the time-domain symbol where uplink reference signals.In specific implementation, it can be stored in terminal There are transmission power and label (for indicating whether allow to carry data in the time-domain symbol where uplink reference signals, for example, mark Label 1 indicate allow carry data, label 0 indicate do not allow carry data) mapping table, as shown in table 2, the transmitting of terminal Power is more than or equal to threshold value A, and the transmission power of corresponding label 0, terminal is less than threshold value A, corresponding label 1.

Mode three：Terminal determines uplink reference signals place according to the order of modulation of uplink and/or code rate Time-domain symbol in whether allow carry data
In view of the order of modulation and code check of uplink usually can be by code modulation mode (Modulation and Coding scheme, MCS) index value uniformly indicates, therefore, determine that uplink refers to according to MCS index values below with terminal Carrying data instance whether is allowed to illustrate in time-domain symbol where signal.
In covering the scenes such as limited, higher transmission power is needed, and more sensitive to PAPR.And in these scenes In, it is directed to adaptive coding and modulating (Adaptive Modulation and Coding) mechanism, the network equipment would generally be Terminal configures lower code check and modulation system, it follows that whether MCS and PAPR is sensitive, there are certain correspondences.Cause This, can be arranged the threshold value B of a MCS index value (index) in terminal, if the MCS indexes of the last time transmission of instruction information instruction Value is more than or equal to threshold value B, then terminal, which can determine, allows to carry data in the time-domain symbol where uplink reference signals, if instruction letter The MCS index values for ceasing the uplink of instruction are less than threshold value B, then terminal can determine in the time-domain symbol where uplink reference signals Do not allow to carry data.By taking LTE as an example, MCS includes altogether a possible index values of 32 (0-31), then it is 5 that threshold value B, which can be arranged, then Correspondingly, when MCS index values are 0-4, corresponding label 0 (does not allow to carry number in the time-domain symbol where uplink reference signals According to), when MCS index values are 5-31, corresponding label 1 (allows to carry data in the time-domain symbol where uplink reference signals), such as Shown in table 3.
Table 3：MCS index values and label mapping table

In the embodiment of the present invention, threshold value B can be pre-defined, alternatively, can also be by system message etc. in systems into Row broadcast notice terminal, or, can also configuration notification terminal be carried out by high-level signaling such as RRC signaling.
Mode four：Terminal according to the waveform of uplink, the transmission power of uplink, the order of modulation of uplink and Whether allow to carry data in time-domain symbol where the determining uplink reference signals of arbitrary combination of code rate
In the embodiment of the present invention, as previously described, because the waveform of uplink, the transmission power of uplink and uplink pass Defeated MCS index values can be used as the factor of judgment for whether allowing to carry data in the time-domain symbol where uplink reference signals, Therefore, terminal can also determine in the time-domain symbol where uplink reference signals whether permit according to the arbitrary combination of above-mentioned three Perhaps data are carried.For example, terminal according to the combination of above-mentioned three come determine in the time-domain symbol where uplink reference signals whether Allow to carry data, in such cases, the configuration of uplink of instruction information instruction includes above-mentioned three, can specifically be arranged on When the waveform of row transmission is SC-FDMA waveforms, MCS index values are less than threshold value B and transmission power is more than or equal to threshold value A, uplink ginseng Examining does not allow to carry data in the time-domain symbol where signal, under remaining situation, in the time-domain symbol where uplink reference signals Allow to carry data.
Aforesaid way one is directed to various ways such as modes four, lower mask body introduces a kind of example.
In step 201, the configuration of the uplink of instruction information instruction includes that the waveform of uplink and first match confidence Breath, the first configuration information includes the transmission power of uplink and/or the MCS index values of uplink, correspondingly, in step In 202, terminal can be determined according to the waveform and the first configuration information of uplink in the time-domain symbol where uplink reference signals Whether allow to carry data.
A kind of realization method in the example is that terminal is if it is determined that the waveform of the uplink of instruction information instruction is SC- FDMA waveforms, and the first configuration information meets the first preset condition, it is determined that permit in the time-domain symbol where uplink reference signals Perhaps data are carried, otherwise, it determines the time-domain symbol where uplink reference signals does not allow to carry data.First configuration information meets First preset condition is specifically as follows：The transmission power of uplink is less than the MCS index values of first threshold and/or uplink More than or equal to second threshold.First threshold and second threshold can be set by those skilled in the art according to actual conditions and experience It sets, does not limit specifically.
In this way, SC-FDMA waveforms are directed to, if the first configuration information meets the first preset condition, uplink Allow to carry data in time-domain symbol where reference signal, i.e. uplink reference signals and data-signal can be accorded in the same time domain Multiplexing on number, it is only last in a subframe when compared to using SC-FDMA waveforms in existing LTE system uplink On one symbol send SRS mode, the embodiment of the present invention can ensure reference signal channel estimating performance on the basis of, Effectively improve the utilization rate of running time-frequency resource.
Another realization method in the example is, terminal determines that the waveform that the terminal uses is OFDM waveforms, and the One configuration information meets the second preset condition, it is determined that do not allow to carry data in the time-domain symbol where uplink reference signals, Otherwise, it determines the time-domain symbol where uplink reference signals allows to carry data.First configuration information meets the second preset condition It is specifically as follows：The transmission power of uplink is more than or equal to third threshold value and/or the MCS index values of uplink are less than the 4th Threshold value.Third threshold value and the 4th threshold value can be arranged by those skilled in the art according to actual conditions and experience, not limit specifically It is fixed.
In this way, OFDM waveforms are directed to, if the first configuration information meets the second preset condition, uplink reference Do not allow to carry data in time-domain symbol where signal, i.e., uplink reference signals and data-signal are not in the same time-domain symbol Upper multiplexing, when compared to using OFDM waveforms in existing LTE system downlink, reference signal and data-signal are always one It is multiplexed on a symbol, the embodiment of the present invention can effectively avoid the reference signal being likely to occur in the prior art from being distorted, and cause The problem of channel estimation inaccuracy.
According to above-mentioned example it is found that by carrying out careful division to different scenes in the embodiment of the present invention, and it is based on drawing Whether scene after point, determining allows to carry data in the time-domain symbol where uplink reference signals, to be multi-transceiver technology In the transmissions of uplink reference signals provide a kind of higher implementation of feasibility.
Step 203, terminal sends uplink signal to the network equipment.
In specific implementation, as shown in Figure 3a, the occupied time-domain symbol of uplink reference signals is symbol 2, symbol 5, symbol 9 With symbol 12, a kind of example, the RE in frequency domain resource can be divided into 3 groupings by terminal, i.e., the RE that number is 1 is the first RE points Group, the RE that number is 2 are the 2nd RE groupings, and the RE that number is 3 is the 3rd RE groupings.At this point, adjacent two in any RE grouping 2 RE are spaced between a RE.It can also include uplink reference letter in the embodiment of the present invention, in the configuration information of uplink reference signals The number of number occupied RE groupings, terminal can be generated according to the number (such as P) of the occupied RE groupings of uplink reference signals P group reference signals, and carried out on the RE during the arbitrary P RE that P group reference signals are respectively mapped in three RE grouping is grouped It sends, wherein the value of P can be 1,2 or 3.
Further, in order to ensure low PAPR characteristics, it can be arranged between P group reference signals and meet preset constraints, In, preset constraints can be that P group reference signals are generated based on the same ZC sequences.
A uplink for terminal is multiplexed and is not multiplexed in the case of two kinds, the formation sequence of uplink reference signals It is identical.A scheme that uplink reference signals are generated based on the same ZC sequences is given below：When multiplexing, it is assumed that generate uplink ginseng The time domain for examining the ZC sequences of signal is expressed as xj(t), the group number of uplink reference signals when wherein j is multiplexing, t is time domain samples； When not being multiplexed then, the time domain for generating the ZC sequences of i-th group of uplink reference signals is expressed as xi(t)=Cixj(t)e-(j-i)θ, wherein Ci, θ be constant.
In this way, due in LTE system downlink reference signal be generated based on full bandwidth, and generate reference signal ZC sequences Row are also based on the quantity generation of the RE of full bandwidth reference signal occupancy, therefore, when reference signal occupies fractional bandwidth transmission When, multiple good cross correlations of terminal room reference signal are cannot be satisfied, and by using above-mentioned side in the embodiment of the present invention RE on one symbol is divided into multiple groupings to carry multigroup reference signal, and met between multigroup reference signal pre- by formula If constraints, this problem can be well solved.
For example, terminal 1 occupies the first RE in symbol 2 and is grouped to send uplink reference signals, and terminal 2 occupies symbol The first RE groupings and the 2nd RE groupings in 2 send uplink reference signals, at this point, since terminal 2 is in the first RE grouping and the Uplink reference signals in two RE groupings are to be generated based on same ZC sequences, and uplink of the terminal 1 in the first RE groupings is joined It examines signal and is also based on ZC sequences generation, so that uplink reference signals and terminal 2 of the terminal 1 in the first RE groupings There is good cross correlation between uplink reference signals in the first RE groupings, effectively avoid interfering with each other.
In the embodiment of the present invention, when Fig. 3 b are a kind of when being multiplexed on same symbol of uplink reference signals and data-signal Frequency resource schematic diagram.As shown in Figure 3b, except occupied by reference signal in occupied first time-domain symbol of uplink reference signals RE other than RE be the occupied RE of the data-signal.
Fig. 3 c are a kind of running time-frequency resource schematic diagram of reference signal and data-signal not when being multiplexed on same symbol.Such as figure Shown in 3c, the RE in occupied second time-domain symbol of uplink reference signals in addition to the occupied RE of reference signal is blank RE。
It should be noted that be in above-mentioned Fig. 3 b and Fig. 3 c be multiplexed on same symbol with reference signal and data-signal with And under two kinds of situations not being multiplexed on same symbol of reference signal and data-signal, pattern (pattern) phase of reference signal It is illustrated with for, the transmission power on RE of reference signal may different from, i.e. Fig. 3 b institutes under two kinds of situations at this time The reference signal transmitting work(of reference signal on RE in the case of the transmission power on RE is less than shown in Fig. 3 c in the case of showing Rate.
In the embodiment of the present invention, reference signal and data-signal be multiplexed on same symbol and reference signal sum number it is believed that Under number two kinds of situations not being multiplexed on same symbol, the pattern of reference signal can not also be identical.Below with reference signal and For the situation that data-signal is not multiplexed on same symbol, the pattern of several possible reference signals is enumerated, respectively such as Fig. 3 d, figure Shown in 3e.Correspondingly, in reference signal and data-signal in the case of being multiplexed on same symbol, reference signal can also use Pattern shown by Fig. 3 d, does not limit specifically.A kind of example, reference signal and data-signal are adopted when being multiplexed on same symbol With the mode shown by Fig. 3 b, and Fig. 3 d or Fig. 3 e institutes do not can be used when being multiplexed on same symbol in reference signal and data-signal The mode shown.
Step 204, the network equipment receives the uplink signal that terminal is sent, and channel estimation, demodulation can be carried out according to configuration Deng.
It should be noted that：(1) time-domain symbol in the embodiment of the present invention can be OFDM symbol, or, or SC-FDMA symbols.(2) time-domain symbol where uplink reference signals can be that terminal and the network equipment are made an appointment, this In the case of kind, terminal can be according to the time-domain symbol where determining uplink reference signals of making an appointment.
Embodiment two：The mode of display
Fig. 4 is the flow diagram corresponding to a kind of communication means provided by Embodiment 2 of the present invention, as shown in figure 4, should Method includes：

Step 402, the network equipment determines the uplink of uplink with reference to letter according to power headroom and/or the SINR of terminal Number whether support and data carry out channeling.For example, when the power headroom of the terminal is less than four thresholdings, the network Equipment determines that the uplink reference signals are not supported to carry out channeling with data；Alternatively, when the Signal to Interference plus Noise Ratio of the terminal When SINR is less than five thresholdings, the network equipment determines that the uplink reference signals of the uplink are not supported to carry out with data Channeling.
Lower mask body enumerates several possible realization methods：
Mode one, the network equipment determine that the power headroom of the terminal is more than or equal to the 5th threshold value and/or the terminal SINR is more than or equal to the 6th threshold value, it is determined that and the uplink reference signals of uplink are supported and data carry out channeling, otherwise, Determine that the uplink reference signals of uplink are not supported to carry out channeling with data.
Example one under the realization method, the power headroom that the network equipment can be reported according to terminal determine the upper of uplink Whether row reference signal is supported to carry out channeling with data.For example, the network equipment can be to uplink reference signals and data-signal Power headroom when being multiplexed on the same symbol sets a deviant, such as 2dB, if the power headroom that terminal reports is 6dB, It is 6dB-2dB=that then reference signal, which is calculated, with the power headroom that data-signal is multiplexed on the same symbol in the network equipment 4dB, and according to the corrected output surplus of 4dB determine terminal uplink send reference signal whether with data-signal in the same symbol It is multiplexed on number；For example, a threshold value D (the 5th threshold value) can be arranged, if the power headroom that terminal reports is more than or equal to threshold value D, it is determined that the uplink reference signals of uplink are supported to carry out channeling with data, if the power headroom that terminal reports is less than Threshold value D, it is determined that the uplink reference signals of uplink are not supported to carry out channeling with data.Wherein, the specific of threshold value D takes Value can be arranged according to actual conditions.
Example two under the realization method, the network equipment calculate the SINR of uplink, and according to measuring and calculating according to the SRS of terminal SINR determine the uplink reference signals of uplink whether support and data carry out channeling.For example, a threshold can be arranged Value E (the 6th threshold value), if SINR is less than threshold value E, it is determined that the uplink reference signals of uplink are not supported with data into line frequency Rate is multiplexed, if SINR is more than or equal to threshold value E, it is determined that the uplink reference signals of uplink are supported multiple into line frequency with data With.Wherein, the specific value of threshold value E can be arranged according to actual conditions.
Example three under the realization method, network equipment considering power surplus and SINR, to determine uplink Whether uplink reference signals are supported to carry out channeling with data.Specifically, power headroom can be set and be more than or equal to the 5th threshold Value and when SINR is more than or equal to six threshold values, the uplink reference signals of uplink are supported to carry out channeling with data, otherwise, The uplink reference signals of uplink are not supported to carry out channeling with data.
Mode two, the network equipment is if it is determined that the power headroom of terminal is less than the 7th threshold value and/or the SINR of the terminal is small In the 8th threshold value, then the uplink reference signals of uplink are not supported to carry out channeling with data, otherwise, it determines uplink Uplink reference signals support with data carry out channeling.Particular content can the above-mentioned realization method of analogy, details are not described herein again.
It should be noted that being only the uplink reference that the network equipment determines uplink in above-mentioned steps 401 and step 402 Whether signal supports a kind of possible example with data progress channeling, and whether uplink reference signals support and data progress Channeling can also be to be made an appointment by agreement, not limit specifically.
Step 403, the network equipment to terminal send configuration information, configuration information include uplink reference signals whether support with Data carry out channeling.
In the embodiment of the present invention, the network equipment can send instruction information in several ways, for example, the network equipment can be with By physical layer signaling, i.e., uplink reference signals are indicated in DCI, alternatively, uplink reference can also be indicated by high-level signaling Signal, or, multiple candidate items of uplink reference signals are indicated by high-level signaling, and make by DCI dynamic instruction terminals With which of multiple candidate items.Concrete mode by DCI dynamic instructions includes but not limited to following several：One, in DCI The middle specific domain of addition indicates uplink reference signals, and the reference signal instructions field of 1 bit is such as added, and bit 1 indicates data-signal The same time-domain symbol can be multiplexed with reference signal, bit 0 indicates that data-signal can not be multiplexed the same time domain with reference signal Symbol.Two, the configuration information of specific domain instruction uplink reference signals is not added in DCI, and area is subject to by scrambler sequence Point.Into after coding, scrambler such as is being carried out using scrambler sequence A to DCI, it is same to indicate that data-signal can be multiplexed with reference signal Time-domain symbol carries out scrambler using scrambler sequence B and indicates that data-signal can not be multiplexed the same time-domain symbol with reference signal.Eventually End when detect DCI, according to detect the scrambler sequence used when DCI determine uplink reference signals whether support and data progress Channeling.
Step 404, terminal receives the configuration information that the network equipment is sent, if uplink reference signals are not supported to carry out with data Channeling, then the terminal, which can be given tacit consent to, does not allow to carry data in the time-domain symbol where the uplink reference signals；On if Row reference signal supports that with data progress channeling, then the time domain where the terminal can give tacit consent to the uplink reference signals accords with Allow to carry data in number.
It should be noted that if uplink reference signals are supported to carry out channeling with data, then terminal gives tacit consent to the uplink Allow to carry data in time-domain symbol where reference signal, but in the time-domain symbol where the uplink reference signals actually generated Whether carry data and has depended on whether that data need to transmit.
Step 405, terminal sends uplink signal to the network equipment.
