S101: the symbolic number according to shared by mini-slot determines the configuration of the corresponding demodulated reference signal DMRS of the mini-slot Type；The corresponding configuration parameter of the Configuration Type include in following at least one of: the cyclic shift of comb teeth (Comb), DMRS Symbol shared by (cyclic shift, CS) and DMRS, the number of at least one configuration parameter in different Configuration Types Amount is different.

It has been stored in advance in base station default between the symbolic number of mini-slot and the Configuration Type of demodulated reference signal DMRS Corresponding relationship, base station is according to the default corresponding relationship between the symbolic number of mini-slot and the Configuration Type of DMRS, and currently quilt Symbolic number shared by the mini-slot of scheduling determines the Configuration Type of the corresponding demodulated reference signal DMRS of the mini-slot.DMRS's The corresponding configuration parameter of Configuration Type includes at least one in following: shared by comb teeth, the cyclic shift of DMRS and DMRS Symbol.

The cyclic shift of DMRS is used to distinguish different user devices (User Equipment, UE) or antenna port is used DMRS sequence, DMRS sequence is a kind of sequence made an appointment between base station and user equipment.

Symbol shared by DMRS includes the quantity of symbol shared by the time-domain position and DMRS of symbol shared by DMRS. The time-domain position of symbol shared by DMRS can be the position where first symbol of mini-slot, can also be the of mini-slot Position where one symbol and the position where the n-th symbol of mini-slot, N are the positive integer greater than 2.Shared by DMRS The position of symbol when being the position where first symbol of mini-slot, indicate that the DMRS is preposition DMRS；Shared by DMRS The position of symbol when being the position where the n-th symbol of mini-slot, indicate that the DMRS is dynamic DMRS.

The quantity of at least one configuration parameter is different in different Configuration Types.For example, comb teeth in different Configuration Types Quantity it is different, the quantity of the cyclic shift of DMRS is different or DMRS shared by symbol quantity it is different.The number of comb teeth comb Amount can be 1, be also possible to 2；The quantity of the cyclic shift of DMRS can be 2, be also possible to 2 or more, DMRS institute The quantity of the symbol accounted for can be 1, be also possible to 2.

Further, in embodiments of the present invention, if symbolic number shared by the mini-slot is the first number, it is determined that institute The Configuration Type for stating the corresponding DMRS of mini-slot is the first Configuration Type；First Configuration Type corresponds to a comb teeth and two Cyclic shift, and the DMRS is preposition DMRS, the preposition DMRS maps to first symbol of the mini-slot.

In the present embodiment, the first number is 2 or 4.Since 2 symbol lengths or 4 meet the mini-slot needle of length Pair mainly low time delay business, meet length to the of less demanding of data rate, therefore for 2 symbol lengths or 4 Mini-slot can could support up 2 stream multiple-input, multiple-output (Multiple-Input Multiple-Output, MIMO), that is, support 2 Two user equipment (UE) multiplexings, the mini- of 2 symbol lengths or 4 symbol lengths are supported in a antenna port multiplexing in other words The DMRS sequence of 2 ports can be mapped in the first symbol of slot.

The corresponding comb teeth of first Configuration Type and two cyclic shifts, and DMRS is preposition DMRS, preposition DMRS mapping To first symbol of mini-slot.In other words, the mini-slot of 2 or 4 symbols can only include the preposition of a symbol DMRS does not include dynamic demodulation reference signal.Wherein, a comb teeth and two cyclic shifts are for indicating in identical scheduling In bandwidth, at most allowing two user equipmenies, (UE is multiplexed, and two corresponding DMRS of user equipment (UE) are moved by circulation Position reaches orthogonal；Or two different ports of the same user equipment (UE) are multiplexed, the corresponding DMRS of different port Reach orthogonal by the value of different cyclic shifts.

Further, in embodiments of the present invention, if symbolic number shared by the mini-slot is the second number, letter is obtained Road time-varying speed.

In embodiments of the present invention, the second number is 7, that is, the mini-slot of 7 symbols.Base station is available to be arrived The channel time-varying speed tested by detection reference signal, and the channel time-varying speed that will acquire and it is preset when speed change Degree threshold value is compared, and preset time-varying speed threshold value can be configured according to the parameter of channel each in practical application, herein With no restrictions.

If the channel time-varying speed is less than or equal to preset time-varying speed threshold value, it is determined that the mini-slot is corresponding The Configuration Type of demodulated reference signal DMRS is the second Configuration Type, and corresponding 2 comb teeth of second Configuration Type and two follow Ring displacement, and the DMRS is preposition DMRS, the preposition DMRS maps to first symbol of the mini-slot.

Corresponding 2 comb teeth of second Configuration Type and 2 cyclic shifts, and DMRS is preposition DMRS, preposition DMRS is mapped to First symbol of mini-slot.2 comb teeth and 2 cyclic shifts indicate in identical scheduling bandwidth, at most allow four UE Carry out with multi-user's multiple-input, multiple-output (Multi-User Multiple-Input Multiple-Output, MU-MIMO) multiplexing or Four ports of the same UE of person carry out single user multiple-input, multiple-output (SU-MIMO) multiplexing.

If the channel time-varying speed is greater than preset time-varying speed threshold value, it is determined that the corresponding demodulation of the mini-slot is joined The Configuration Type for examining signal DMRS is third Configuration Type；Corresponding 2 comb teeth of the third Configuration Type and two cyclic shifts, And the DMRS includes that preposition DMRS and dynamic DMRS, the preposition DMRS map to first symbol of the mini-slot, institute State the n-th symbol that dynamic DMRS maps to the mini-slot, wherein N is the positive integer greater than 2.

Corresponding 2 comb teeth of third Configuration Type and 2 cyclic shifts, and DMRS includes preposition DMRS and dynamic DMRS, it is preceding First symbol that DMRS maps to mini-slot is set, dynamic DMRS maps to the n-th symbol of mini-slot, wherein N is greater than 2 Positive integer.

Further, in embodiments of the present invention, the value of N is 5.

Referring to Figure 2 together, Fig. 2 is a kind of data for frame structure based on self-contained formula that one embodiment of the invention provides Scheduling instance figure.Wherein, the frame structure of self-contained (self-contained) formula, i.e., under including simultaneously inside the same subframe Row symbol DL, protection interval (Guard Period, GP) and uplink symbol UL.As shown in Fig. 2, in the subframe of a self-contained formula Data area include a symbol lengths be 7 mini-slot.Preposition DMRS is mapped in first symbol of mini-slot, dynamic DMRS is mapped in the 5th symbol of mini-slot.Wherein, first symbol of mini-slot corresponds to the 3rd symbol of the subframe Number, the 5th symbol of mini-slot corresponds to the 7th symbol of the subframe.

In Fig. 2, between mapping between the symbol of preposition DMRS and the symbol for mapping dynamic DMRS in mini-slot Every 4 symbols, in other embodiments, between the symbol for mapping the symbol of preposition DMRS and for mapping dynamic DMRS, 5 symbols can also be spaced.

S102: according to the Configuration Type determine at least one user equipment for being dispatched in the mini-slot and it is described extremely The value of few corresponding configuration parameter of a user equipment.

Base station can determine at least one that uplink scheduling or descending scheduling are carried out in the mini-slot according to Configuration Type User equipment.For example, if the symbol lengths of mini-slot are 2 or 4, it is determined that its Configuration Type is the first Configuration Type, In the mini-slot, under the same scheduling bandwidth, two user equipment (UE)s can be at most dispatched simultaneously.Uplink scheduling refers to user Equipment sends data and DMRS in the mini-slot, and descending scheduling refers to that base station sends data and DMRS in the mini-slot.

It is respectively right that the value of the configuration parameter of the corresponding DMRS of UE can be the configuration parameter for determining that the Configuration Type is included The value answered.Wherein, configuration parameter described in S102 can be comb teeth and cyclic shift CS, and the symbolic number that DMRS is occupied And position can be determined by the Configuration Type of DMRS.

For example, 0 expression odd subcarriers can be selected to carry when the collection of the value of comb teeth Comb is combined into { 0,1 } in Configuration Type DMRS selects 1 expression even subcarriers to carry DMRS；Or 1 expression odd subcarriers can be selected to carry DMRS, select 0 expression even number Subcarrier carries DMRS.

When 2 UE are dispatched in base station in the mini-slot, and two UE are multiplexed, if the quantity of comb teeth Comb is in Configuration Type 1, then the value of the Comb of 2 UE is identical, can be 0 or is 1.Assuming that the CS value collection of DMRS is combined into { 0,3,6,9 }, it is multiple Two UE reach orthogonal by choosing different values respectively.

That is, if when the Configuration Type that base station determines is the first Configuration Type, if scheduling and only takes up one UE One antenna port, then, base station is only it needs to be determined that the value of comb teeth；If dispatching two antenna ports of a UE and multiplexing, that Base station it needs to be determined that the CS of the DMRS of the value of comb teeth and two antenna ports value.If dispatching 2 UE, base station is needed Determine the value of the value of comb teeth and the CS of two corresponding DMRS of UE.

Show also referring to the DMRS that Fig. 3 and Fig. 4, Fig. 3 are the mini-slot of 2 symbol lengths provided in an embodiment of the present invention It is intended to；Fig. 4 is the DMRS schematic diagram of the mini-slot of 4 symbol lengths provided in an embodiment of the present invention.In Fig. 3 or Fig. 4, base station is true The value of fixed comb teeth is 0, indicates DMRS sequence mapping to odd subcarriers, carries DMRS by odd subcarriers.

Please refer to fig. 5, Fig. 5 be another embodiment of the present invention provides a kind of frame structure based on self-contained formula number According to scheduling instance figure.As shown in figure 5, data area in the subframe of a self-contained formula include the first mini-slot, second it is micro- when Gap and third mini-slot.The symbol lengths of first mini-slot and the second mini-slot are 2, and the symbol lengths of third mini-slot are 4.UE1 is scheduled in the first mini-slot, and UE2 and UE3 are scheduled in third mini-slot, and number is sent by way of MU-MIMO According to.

For UE1, preposition demodulated reference signal is located on the 1st symbol of the first mini-slot, occupies odd subcarriers；It is right In UE2 and UE3, preposition demodulated reference signal is located on the 1st symbol of third mini-slot, occupy odd subcarriers, UE2 and The DMRS of UE3 on frequency domain by using the value of different CS to keep orthogonal.The value of CS can specifically be set according to the actual situation It sets, herein with no restrictions.

Further, however, it is determined that Configuration Type be the second Configuration Type when, or determine Configuration Type match for third When setting type, if scheduling at least two UE, base station is it needs to be determined that the value of comb teeth and the corresponding DMRS of each UE The value of CS.

Since the mini-slot of 7 symbol lengths needs synthesis to take into account time delay and data-rate requirements, for 7 The mini-slot for meeting length could support up 4 stream MIMO, support 4 antenna port multiplexings, the mini-slot of 7 symbol lengths The DMRS sequence of 4 ports can be mapped.

The DMRS sequence of different antenna ports is distinguished by shared in a frequency domain comb teeth and CS.Any two antenna The value of the corresponding comb teeth in port may be the same or different.

If the quantity of comb teeth is 1, it is 0 or 1 that the value of the comb teeth for the UE being multiplexed is identical, occupies identical sub- load Wave, i.e. multiplexing odd subcarriers or even subcarriers；If the quantity of comb teeth is 2, two UE can occupy different sons Carrier wave, one value are 0, another value is 1.

For example, the value of the corresponding comb teeth of the first UE indicates that odd subcarriers carry DMRS；2nd UE and the 3rd UE is corresponding The value of comb teeth indicate that even subcarriers carry DMRS, and the DMRS sequence of the DMRS sequence of the 2nd UE and the 3rd UE pass through the area CS Point.

For example, the value of the corresponding comb teeth of the 2nd UE indicates the even subcarriers carrying in first symbol of mini-slot DMRS；The value of the corresponding comb teeth of 3rd UE indicates that the even subcarriers in first symbol of mini-slot carry DMRS.2nd UE Using the 3rd DMRS sequence, the 3rd UE use the 4th DMRS sequence, the 3rd DMRS sequence and the 4th DMRS sequence by CS into Row is distinguished.

Referring to Fig. 6, Fig. 6 be another embodiment of the present invention provides demodulated reference signal sending method implementation process Figure.The present embodiment and the difference of a upper embodiment are: the data-handling efficiency in order to promote base station and UE, when this is micro- When at least one user equipment of gap scheduling is only configured a comb teeth, the sending method of demodulated reference signal further includes S204. Wherein, S201~S203 is identical as S101~S103 in a upper embodiment in this example, referring specifically in a upper embodiment The associated description of S101~S103, does not repeat herein.

S204: in the symbol shared by the DMRS, subcarrier other than the subcarrier shared by the DMRS send or Receive data.

Referring to Fig. 4, as shown in figure 4, data area in the subframe of a self-contained formula include the first mini-slot, Second mini-slot and third mini-slot.The symbol lengths of first mini-slot and the second mini-slot are 2, the symbol of third mini-slot Number length is 4.UE1 is scheduled in the first mini-slot, and UE2 and UE3 are scheduled in third mini-slot, and is entered by multi-user more more The mode of (Multi-User Multiple-Input Multiple-Output, MU-MIMO) sends data out.

For UE1, preposition DMRS is located on the 1st symbol of the first mini-slot, occupies odd subcarriers, even subcarriers It can be used for mapping data；For UE2 and UE3, preposition DMRS is located on the 1st symbol of the second mini-slot, occupies odd number By using the value of different CS to keep orthogonal on frequency domain, even subcarriers can be used for reflecting the DMRS of carrier wave, UE2 and UE3 Penetrate data.The value of CS can be specifically configured according to the actual situation, herein with no restrictions.

Base station passes through the Configuration Type that different DMRS is arranged, and the symbol according to shared by mini-slot in embodiments of the present invention Number determines the Configuration Type of its corresponding DMRS, guarantees the real-time for carrying out channel estimation by DMRS, guarantees channel estimation Performance.

In addition, increasing dynamic DMRS when channel time-varying speed is greater than preset time-varying speed threshold value to guarantee that channel is estimated Performance is counted, avoids carrying out new estimation only with preposition DMRS and the channel estimation errors of several symbols behind mini-slot being caused to become Greatly；Increase by a column dynamic DMRS, only to reduce pilot-frequency expense.

Referring to Fig. 7, Fig. 7 is the implementation flow chart of the method for reseptance of demodulated reference signal provided in an embodiment of the present invention, In the corresponding embodiment of Fig. 7, the executing subject of process is user equipment (User Equipment, UE).The user equipment is The terminal device that can be communicated with the network side equipment, the user equipment can be mobile phone, tablet computer, notebook electricity Brain, palm PC, mobile internet device (mobile internet device, MID), wearable device (such as intelligent hand Table (such as iWatch), Intelligent bracelet, pedometer etc.), etc..

When the Configuration Type of DMRS is third Configuration Type, the value of comb teeth is 0 in third Configuration Type, the value of CS is 0, When the quantity of symbol shared by DMRS is 2, the position of symbol shared by DMRS is first symbol and the 5th symbol, UE is obtained The sequence of the corresponding preposition DMRS of third Configuration Type and the sequence of dynamic DMRS are taken, and according to the value of comb teeth and the value of CS The subcarrier of the sequence of preposition DMRS to be mapped is determined from the subcarrier that first symbol of the mini-slot is included, it is micro- from this The subcarrier of the sequence of dynamic DMRS to be mapped is determined in the subcarrier that 5th symbol of time slot is included.

S704: the sequence of the DMRS is mapped into the subcarrier of the determination or in the subcarrier demodulation of the determination The sequence of the DMRS.

When the Configuration Type of DMRS is the first Configuration Type, and the subcarrier determined is odd subcarriers, passed in uplink In defeated, the sequence of preposition DMRS is mapped to the odd subcarriers in first symbol of the mini-slot by UE；Alternatively, being passed in downlink It, will be in the preposition DMRS of the odd subcarriers demodulation odd subcarriers carrying of the first of the mini-slot symbol in defeated.

When the Configuration Type of DMRS is third Configuration Type, determining subcarrier is symbol shared by odd subcarriers and DMRS Number position when being first symbol and the 5th symbol, in uplink, it is micro- that the sequence of preposition DMRS is mapped to this by UE Odd subcarriers in first symbol of time slot, and the sequence of dynamic DMRS is mapped to the 5th symbol of the mini-slot In odd subcarriers；Alternatively, in downlink transfer odd number will be demodulated in the odd subcarriers of the first of the mini-slot symbol The preposition DMRS of subcarrier carrying, and the odd subcarriers demodulation odd subcarriers carrying of the 5th symbol in the mini-slot Dynamic DMRS.

UE obtains the sequence of the corresponding preposition DMRS of third Configuration Type and the sequence of dynamic DMRS, and according to comb teeth Value and the value of CS determine the sequence of preposition DMRS to be mapped from the subcarrier that first symbol of the mini-slot is included Subcarrier determines that the son of the sequence of dynamic DMRS to be mapped is carried from the subcarrier that the 5th symbol of the mini-slot is included Wave.

Wherein, in uplink, DMRS does channel estimation for base station.In downlink transfer, DMRS does channel for UE and estimates Meter.
