Step 501：At least one DMRS functions that terminal needs perform are divided at least one configuration level.

And the DMRS functions that terminal needs perform are divided into the first configuration level by the embodiment of the present invention, network side equipment With the second configuration level.Wherein, a DMRS function is included at least in each configuration level.That is, based on downlink business Subframe in, in the first configuration level and the second configuration level include control channel demodulation function, Traffic Channel demodulation function, At least one of in RRM measurements function, phase noise estimation function.In the subframe based on uplink service, first configuration etc. Grade and the second configuration level kind include control channel demodulation function, instruction terminal sends Traffic Channel DMRS functions and indicates eventually End sends at least one in control channel DMRS functions.

Further, which specific DMRS function is located at which configuration level, and network side equipment can be according to the tool of DMRS Body function and demand determine so that the DMRS functions of high configuration level can aid in the execution of the DMRS functions of low configuration level, So as to further reduce DMRS expenses.

It is therefore preferred that in the subframe based on downlink business, the DMRS functions in first configuration level include control Channel demodulation function processed；DMRS functions in second configuration level include Traffic Channel demodulation function, RRM measurement functions and phase At least one of in noise estimation.For example, when the DMRS in the first configuration level includes control channel demodulation, and second configuration etc. Grade in DMRS functions include Traffic Channel demodulate when, it is contemplated that control channel will be demodulated first, and DMRS have covering requirement and Transmission reliability requirement is arranged to the first configuration level so can demodulate control channel, and can in view of Traffic Channel DMRS To indicate dynamic change according to control channel according to needed for practical business transmission, second is arranged to so Traffic Channel can be demodulated Configuration level.

In addition, in the subframe based on downlink business, DMRS functions are different, then corresponding to the configuration parameter of the DMRS functions Included particular content is different.Specifically, corresponding to each single item DMRS functions configuration parameter include antenna port group mark, At least one of in time domain density and frequency domain density.I.e. first order configuration parameter include first antenna port set mark, At least one of in first time domain density and the first frequency domain density.Wherein, the mark of first antenna port set indicates first day The running time-frequency resource that line group port occupies；First frequency domain density indicates first antenna port set in fractional bandwidth or full bandwidth or subband The interior ratio for occupying subcarrier in frequency domain；First time domain density instruction first antenna port set occupies in a Transmission Time Interval The ratio of time-domain symbol.

Accordingly, when first order configuration parameter includes the mark of first antenna port set, the first time domain density and first During this three contents of frequency domain density, network side equipment selects its own antenna port supported first；Then, according to first DMRS functions (i.e. control channel demodulation function, Traffic Channel demodulation function, RRM measurements function and the phase that configuration level includes At least one of in the noise estimation function of position) from the antenna port that network side equipment is supported, it selects to match somebody with somebody for execution first Put the first antenna port set for the DMRS functions that grade includes；Again, (such as type of service, it is according to network configuration situation System frequency) and the DMRS functions that include of the first configuration level, it determines to perform the DMRS that the first configuration level includes First time domain density of function and the first frequency domain density, so as to obtain the particular content included by the first order configuration parameter.

Furthermore it is preferred that when first order configuration parameter is sent to the terminal, it is specially：Disappeared by broadcast At least one of in breath, radio resource control signaling, the control unit of Medium Access Layer and the instruction of physical layer control message, by institute It states first order configuration parameter and is sent to the terminal.First order configuration parameter is sent the embodiment provides a variety of To the mode of terminal, first order configuration parameter is reasonably selected so as to the actual disposition according to network and operation conditions Sending method.

Step 503：In subframe based on downlink business, the of the DMRS functions that second configuration level includes is determined Two-level distribution parameter, and second level configuration parameter is sent to the terminal.

Wherein, in the subframe based on downlink business, the second configuration level includes control channel demodulation function, business letter Road demodulation function, RRM measurements function, in phase noise estimation function at least one of, then second level configuration parameter include with At least one phase in control channel demodulation function, Traffic Channel demodulation function, RRM measurements function, phase noise estimation function Corresponding configuration parameter.

In addition, in the subframe based on downlink business, DMRS functions are different, then corresponding to the configuration parameter of the DMRS functions Included particular content is different.Specifically, corresponding to each single item DMRS functions configuration parameter include antenna port group mark, At least one of in time domain density and frequency domain density.I.e. second level configuration parameter include the second antenna port group mark, At least one of in second time domain density and the second frequency domain density.Wherein, the mark of the second antenna port group indicates second day The running time-frequency resource that line group port occupies；Second frequency domain density indicates the second antenna port group in fractional bandwidth or full bandwidth or subband The interior ratio for occupying subcarrier in frequency domain；Second time domain density indicates that the second antenna port group occupies in a Transmission Time Interval The ratio of time-domain symbol.

Accordingly, when the second level, configuration parameter includes the mark of the second antenna port group, the second time domain density and second During this three contents of frequency domain density, network side equipment selects its own antenna port supported first；Then, according to second DMRS functions (i.e. control channel demodulation function, Traffic Channel demodulation function, RRM measurements function and the phase that configuration level includes At least one of in the noise estimation function of position) from the antenna port that network side equipment is supported, it selects to match somebody with somebody for execution second Put the second antenna port group of the DMRS functions that grade includes；Again, (such as type of service, it is according to network configuration situation System frequency) and the DMRS functions that include of the second configuration level, it determines to perform the DMRS that the second configuration level includes Second time domain density of function and the second frequency domain density, so as to obtain the particular content included by the second level configuration parameter.

Wherein, remaining parameter in second level configuration parameter refers to remove in second level configuration parameter and join with first order configuration Number sends jointly to the parameter outside the partial parameters of terminal.For example, when second level configuration parameter includes antenna port group It is identified as 0, time domain density 1, when frequency domain density is 1/6, matches somebody with somebody if antenna port group to be identified as to 0 this parameter with the first order Parameter is put together by broadcast message, radio resource control signaling, the control unit of Medium Access Layer and physical layer control message In instruction at least one of, be sent to terminal, then remaining parameter in second level configuration parameter include time domain density for 1, Frequency domain density is 1/6 this two parameters.

It can be seen from the above, second level configuration parameter is sent to the modes of terminal the embodiment provides a variety of, The sending method of second level configuration parameter is reasonably selected so as to the actual disposition according to network and operation conditions.Separately Outside, the rest part parameter in second level configuration parameter is made in a manner that physical layer descending control information is sent to terminal Remaining parameter obtained in second level configuration parameter is carried by physical layer descending control information, has faster information transmission speed, So as to reduce physical layer descending control information expense.

Step 504：In subframe based on uplink service, the of the DMRS functions that first configuration level includes is determined Level-one configures parameter, and first order configuration parameter is sent to the terminal.

Wherein, in the subframe based on uplink service, the first configuration level includes control channel demodulation function, instruction eventually End sends at least one in Traffic Channel DMRS functions and instruction terminal transmission control channel DMRS functions, then the first order configures Parameter includes sending Traffic Channel DMRS functions with control channel demodulation function, instruction terminal and instruction terminal sends control letter At least one corresponding configuration parameter in road DMRS functions.

In addition, in the subframe based on uplink service, DMRS functions are different, then corresponding to the configuration parameter of the DMRS functions Included particular content is different.Specifically, corresponding to each single item DMRS functions configuration parameter include antenna port group mark, At least one of in time domain density and frequency domain density.I.e. first order configuration parameter include first antenna port set mark, At least one of in first time domain density and the first frequency domain density.Wherein, the mark of first antenna port set indicates first day The running time-frequency resource that line group port occupies；First frequency domain density indicates first antenna port set in fractional bandwidth or full bandwidth or subband The interior ratio for occupying subcarrier in frequency domain；First time domain density instruction first antenna port set occupies in a Transmission Time Interval The ratio of time-domain symbol.

Accordingly, when first order configuration parameter includes the mark of first antenna port set, the first time domain density and first During this three contents of frequency domain density, network side equipment selects its own antenna port supported first；Then, according to first (i.e. control channel demodulation function, instruction terminal send Traffic Channel DMRS functions and refer to the DMRS functions that configuration level includes Show that terminal sends at least one in control channel DMRS functions) from the antenna port that network side equipment is supported, select use In the first antenna port set for performing the DMRS functions that the first configuration level includes；Again, according to network configuration situation (such as Type of service, system frequency) and the DMRS functions that include of the first configuration level, it determines to perform in the first configuration level Including DMRS functions the first time domain density and the first frequency domain density, so as to obtain included by first order configuration parameter Particular content.

Step 505：In subframe based on uplink service, the of the DMRS functions that second configuration level includes is determined Two-level distribution parameter, and second level configuration parameter is sent to the terminal.

Wherein, in the subframe based on uplink service, the second configuration level includes control channel demodulation function, instruction eventually End sends at least one in Traffic Channel DMRS functions and instruction terminal transmission control channel DMRS functions, then the second level configures Parameter includes sending Traffic Channel DMRS functions with control channel demodulation function, instruction terminal and instruction terminal sends control letter At least one corresponding configuration parameter in road DMRS functions.

In addition, in the subframe based on uplink service, DMRS functions are different, then corresponding to the configuration parameter of the DMRS functions Included particular content is different.Specifically, corresponding to each single item DMRS functions configuration parameter include antenna port group mark, At least one of in time domain density and frequency domain density.I.e. second level configuration parameter include the second antenna port group mark, At least one of in second time domain density and the second frequency domain density.Wherein, the mark of the second antenna port group indicates second day The running time-frequency resource that line group port occupies；Second frequency domain density indicates the second antenna port group in fractional bandwidth or full bandwidth or subband The interior ratio for occupying subcarrier in frequency domain；Second time domain density indicates that the second antenna port group occupies in a Transmission Time Interval The ratio of time-domain symbol.

Accordingly, when the second level, configuration parameter includes the mark of the second antenna port group, the second time domain density and second During this three contents of frequency domain density, network side equipment selects its own antenna port supported first；Then, according to second (i.e. control channel demodulation function, instruction terminal send Traffic Channel DMRS functions and refer to the DMRS functions that configuration level includes Show that terminal sends at least one in control channel DMRS functions) from the antenna port that network side equipment is supported, select use In the second antenna port group for performing the DMRS functions that the second configuration level includes；Again, according to network configuration situation (such as Type of service, system frequency) and the DMRS functions that include of the second configuration level, it determines to perform in the second configuration level Including DMRS functions the second time domain density and the second frequency domain density, so as to obtain included by second level configuration parameter Particular content.

In conclusion either in the still subframe based on uplink service of the subframe based on downlink business, as long as eventually End performs different DMRS functions, and the antenna port group applied may be different, and the Internet resources applied may also be different, The i.e. different corresponding time domain densities of DMRS functions is different with frequency domain density.And the embodiment of the present invention, either with downlink Subframe based on the business still subframe based on uplink service, can be according to actual DMRS function dynamic configuration time-frequencies Resource Density, and no longer using a kind of fixed pattern, DMRS expenses are saved, so as to increase the money for business transmission Source, and then improve system spectral efficiency.I.e. the embodiment of the present invention is applicable not only to following 5G mobile telecommunication system downs DMRS could be applicable to the transmission of uplink DMRS.In addition, the embodiment of the present invention applies also for and other kinds of reference signal (Reference Signal, RS), such as channel state information reference signals (Channel State Information Reference Signal, CSI-RS).

Further, either in the still subframe based on uplink service of the subframe based on downlink business, the second level Configure the subset for the first antenna port set that the second antenna port group in parameter is configured for the first order in parameter.That is the second antenna Port set is selected from first antenna port set, then need not can again detect other antennas outside first port group Port so as to reduce signaling consumption, further reduces DMRS expenses.

Further, either in the still subframe based on uplink service of the subframe based on downlink business, the first order There are intersections for the second time domain density in the first time domain density and second level configuration parameter in configuration parameter.Such as first configuration In grade and the second configuration level include control channel demodulation function, then the second level configuration parameter in control channel solution Power Regulation Can corresponding time domain density, can directly using in first order configuration parameter with the corresponding time domain of control channel demodulation function Density so as to be further simplified the determination process of second level configuration parameter, and then further reduces DMRS expenses.
