Background technique

In LTE system, user can pass through dedicated DMRS (DeModulation Reference Signal, demodulation Reference signal) channel estimation is carried out, wherein DMRS signal executes pre-encode operation identical with data-signal.LTE Rel-10 with Upper version can support that 8 (utilize orthogonal covering codes OCC-Orthogonal Cover Code) or frequency division side in such a way that code divides The orthogonal DMRS port of formula --- port 7 to 14, (l in Fig. 1 indicates each slot s lot in LTE subframe structure as shown in Figure 1 Notation index, 7 symbols of each time slot, from 0-6)；Port 7,8,11,13 is multiplexed the identical RE on one group of subcarrier (Resource Element, resource unit), is distinguished by OCC；Port 9,10,12,14 is multiplexed the phase on another group of subcarrier Same RE, is distinguished also by OCC.

In order to realize transparent transmission and save the expense that DMRS occupies running time-frequency resource (RE), the MU- in LTE Rel-10 Transmission mode is only by MIMO (Multi-User Multiple-Input Multiple-Output, multi-user multiple input multiple output technology) Using port 7,8, i.e., only 2 DMRSs orthogonal by OCC, while can be by quasi- orthogonal (identical with data channel pre- Coding/wave beam forming and different DMRS scramble sequences) mode distinguishes, distribute to the DMRS of multiple data flows.There is only ends When mouth 7,8, OCC length is 2.Downlink Control Information (DCI, Downlink Control Information) includes for user point NSCID (scrambling identity, scrambling code mark) instruction of the DMRS port and description DMRS scramble sequence matched.? Prior art of the 3GPP standard as extensive antenna --- Quan Wei-MIMO's (FD-MIMO, Full Dimension-MIMO) In discussion, propose the extended mode of DMRS to support to increase a certain number of numbers of users, for example, using port 7,8,11, 13, OCC length are 4, increase the quantity of orthogonal DMRS.

But in LTE system, no matter how increasing the orthogonal port number of DMRS, the pilot tone pattern of DMRS is fixed, As long as this user knows the port resource of oneself distribution, so that it may carry out infomation detection reconciliation according to fixed DMRS pilot tone pattern It adjusts.

In addition, after 5G newly eats dishes without rice or wine (NR:New Radio) project initiation, in order to reduce processing delay, lifting system Can, DMRS pilot tone pattern is designed and defined again.In new DMRS pilot tone pattern, there are many different pilot patterns Sample, concrete configuration are as follows:

Configuration (configuration) 1:

1.DMRS symbolic number is 1: using comb2+CS2, maximum is supported to 4 ports.

(1) see Fig. 2, wherein comb2 is exactly the multiplexing relationship of comb2 between frequency domain multiplexing, such as port 0 and 2.CS2 Sequence between port is multiplexed using cyclic shift mode (cyclic shifts), for example is exactly between port 0 and 1 The multiplexing relationship of CS2.

2.DMRS symbolic number is 2: being used comb2+CS2+TD-OCC ({ 11 } and { 1-1 }), maximum is supported to 8 ports.

(2) see that Fig. 3, TD-OCC are time domain OCC (Orthogonal Cover Code, orthogonal code) multiplexing, such as port 0/ It is multiplexed between 1 and 4/5 using time domain OCC.

Configuration 2

1.DMRS symbolic number is 1: being used 2-FD-OCC (adjacent frequency domain RE), maximum is supported to 6 ports.

(1) see Fig. 4,2-FD-OCC, i.e. frequency domain OCC multiplexing, for example be exactly frequency domain OCC multiplexing between port 0 and 1.In addition FDM (Frequency Division Multiplexing, frequency division multiplex) mode is used between other ports, such as FDM mode is used between port 0/1 and 2/3.

2.DMRS symbolic number is 2: using 2-FD-OCC (adjacent frequency domain RE)+TD-OCC ({ 11 } and { 1-1 }), maximum branch It holds to 12 ports.

(1) see that Fig. 5, TD-OCC are time domain OCC (Orthogonal Cover Code) multiplexing, such as port 0/1 and 6/7 Between using time domain OCC be multiplexed.

The case where can be seen that configuration1 from the various pattern of above-mentioned DMRS (mode), if supported most Large port number is no more than 4, then can be configured with the pattern of Fig. 2, if it exceeds 4, but 8 are no more than, it can be with Fig. 3's Pattern is configured；The case where configuration2, can be with Fig. 4's if the maximum port number supported is no more than 6 Pattern is configured, if it exceeds 6, but 12 are no more than, it can be configured with the pattern of Fig. 5.Port number in this is Refer to the port number summation for all users being multiplexed on the resource location.

Further, in NR, basic confirmation needs the content for the DCI information for including as follows:

(1) resource information: including carrier information and time-frequency resource allocating；

(2) MCS (Modulation and Coding Scheme, modulation and coding strategy) information；

(3) HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat-request) relevant information: packet It is indicated containing new data, RV (Redundancy Version, redundancy versions), HARQ process etc.；

(4) the related letter of PUCCH (Physical Uplink Control CHannel, physical uplink control channel) Breath: including power and resource information；

(5) multiple antennas relevant information: include antenna port, scrambling code ID and number of plies etc.；

(6) CSI (Channel State Information, channel state information) relevant information: comprising in CSI measurement Report mechanism；

(7) SRS (Sounding Reference Signal, detection reference signal) relevant information；

(8) RNTI (Radio Network Tempory Identity, radio network temporary identifier).

Wherein multiple antennas information includes the content that DMRS configuration needs, and there is presently no determinations.And for determining DMRS The pattern of various configurations, in MU-MIMO, on different running time-frequency resources, the number of users of multiplexing is different, then there is difference Resource on concurrent multiplexing DMRS port number it is different, according to existing DMRS configuration information, different port numbers may make With different DMRS pilot tone patterns.In order to need to the DMRS pilot tone drawing information applied on terminal notification difference running time-frequency resource A kind of multiple antennas configuration information is included in DCI information, is notified to terminal UE, and still, in the prior art and there is no about this The scheme of DMRS multiple antennas configuration, so that DCI information can not normal transmission.

It is second, described according to the scheduling divided number of resource, determine the occupied signaling of the Downlink Control Information The step of bit length includes: the divided number of scheduling resource for receiving base station and predetermined bit signaling being used to send；According to institute The scheduling divided number of resource is stated, determines the occupied signaling bit length of the Downlink Control Information.

Such mode is that the occupied signaling bit length of Downlink Control Information is directly informed by base station.Terminal is in addition to knowing It dispatches outside the divided number of resource, bit length needed for can also knowing predetermined bit signaling (can be base station and terminal It makes an appointment).The actually determined signaling bit length in addition to occupancy needed for Downlink Control Information of terminal is outside one's consideration herein, further includes The signaling bit length occupied needed for predetermined bit signaling.

It is also understood that determining that the Downlink Control Information is occupied according to the scheduling divided number of resource Before signaling bit length, the transmission method further include: receive the scheduling resource quilt that base station uses predetermined bit signaling to send The number of segmentation.

Below with reference to base station and terminal two sides to the transmission method of the Downlink Control Information provided in an embodiment of the present invention It is further described.

In view of 5G newly eats dishes without rice or wine under (NR), big band width configuration, PRB (Physical Resource Block object are needed support Manage resource block) quantity is very big, in order to reduce processing complexity, new resource allocation unit RBG (Resource is defined in NR Block Group, resource set of blocks), each RBG includes x PRB, and specific x value passes through high-rise configuration.

When MU-MIMO, base station distributes respective occupancy resource according to the traffic needs of different user, and thus having can The number of users being multiplexed in different RBG resources difference can occur, total port number is different.But optional port under normal circumstances Number ratio RBG resource number is few, so can have each port number corresponds to multiple RBG index.Port number cited below is just The total port number of all users in the resource referred to.

For in NR, different port numbers is possible to using different DMRS pattern, correct in order to enable the terminals to Identification DMRS pilot tone occupy resource location, to carry out correct data receiver and demodulation, thus this gives The scheme for how giving the total port number of terminal notification, both considers signaling overheads, it is contemplated that accuracy.

At present from the DMRS of Fig. 1 to Fig. 4 configuration it can be seen that, need to notify to the possible port number of terminal, Fig. 1 and Possible port number is { 1,2,3,4,5,6,7,8 } when Fig. 2, when Fig. 3 and Fig. 4 possible port number be 1 to 12 ports 1,2,3, 4,5,6,7,8,9,10,11,12}.If notifying all possible port numbers, the signaling overheads of 4 bits is needed, expense compares Greatly, several processing examples are given below, can reduce signaling overheads and (notify all users of concurrent multiplexing in scheduling resource Total port number information).

Example one:

In conjunction in Fig. 1 to Fig. 4 it is considered that DMRS configuration in, each resource units are at least multiplexed 2 DMRS ports, also It is to say, if total port number of MU-MIMO multiplexing is odd-numbered port, is provided with the occupied DMRS pilot tone of even port after adding 1 Source is identical, therefore can only notify even port, is notified by DCI information to terminal.

For Fig. 1 and Fig. 2, i.e. DMRS configuration 1, one shares 4 possible port numbers { 2,4,6,8 }, can be refered in particular to by 2 ratios Show；

For Fig. 3 and Fig. 4, i.e. DMRS configuration 2, one shares 6 possible port numbers { 2,4,6,8,10,12 }, can be by 3 Bit indication.

In addition, if total port number of MU-MIMO multiplexing is even port, it is occupied with the odd-numbered port after subtracting 1 DMRS pilot resources are also identical, therefore can also only notify odd-numbered port, notified by DCI information to terminal.

For Fig. 1 and Fig. 2, i.e. DMRS configuration 1, one shares 4 possible port numbers { 1,3,5,7 }, can be refered in particular to by 2 ratios Show；

For Fig. 3 and Fig. 4, i.e. DMRS configuration 2, one shares 6 possible port numbers { 1,3,5,8,9,11 }, can be by 3 Bit indication.

Port number in the present embodiment can be transmitted by index.

Example two:

In conjunction in Fig. 1 to Fig. 4 it is considered that same DMRS configuration in there are the differences of DMRS symbol numbers, it is possible to The difference of total port number is obtained according to the difference of symbolic number by the symbolic number that DCI information notifies DMRS to occupy to terminal.It should Information is notified by DCI information to terminal.It can be indicated by 1 bit.

It can make an appointment between base station and terminal: if indication bit is 0, represent DMRS and configure 1 or DMRS configuration 2 DMRS symbolic number is 1, while indicating that total port number of multiplexing is no more than 4 (DMRS configurations 1) or is no more than 6 (DMRS configurations 2).

If indication bit is 1, representing DMRS and configuring the DMRS symbolic number of 1 or DMRS configuration 2 is 2, while indicating multiple Total port number is no more than 8 (DMRS configurations 1) simultaneously not less than 4 or is no more than 12 (DMRS configurations 2) simultaneously not less than 6.

It is also assumed that the lower port set indicated of two kinds of DMRS configurations is respectively { 4,8 } and { 6,12 }.With 1 bit table Show.

Between certain base station and terminal make an appointment can also (the corresponding relationship of indication bit and symbolic number) with it is upper It is opposite to state description；Be exactly such as indication bit be 0, represent DMRS configure 1 or DMRS configuration 2 DMRS symbolic number be 2, other Analogize.

Due to having certain deviation according to the indicative port number of this method and actual port number, terminal can be above-mentioned Further blind examination on the basis of information, judges the port number being actually multiplexed, and then carries out subsequent data reception and demodulation (cannot Direct blind examination influences terminal reception because blind examination has error).

Example three:

Example two provide shared by the instruction DMRS by way of signed number, total port number for being multiplexed to terminal notification Information is a kind of relatively coarse method, needs to improve accuracy by the blind examination ability of terminal.This example on this basis, Total port number of notice is encrypted on the basis of example two and (increases packing density), the complexity of terminal blind examination is reduced. It can be by 2 bit indications.

Such as: for Fig. 1 and Fig. 2, i.e. DMRS configuration 1, one shares 4 possible port numbers { 2,4,6,8 }, can be by 2 Bit indication；

For Fig. 3 and Fig. 4, i.e. DMRS configuration 2, one share 4 possible port numbers { 4,6,8,12 } or 4,6,10, It 12 }, can be by 2 bit indications.

Due to still having certain deviation according to the indicative port number of this example and actual port number, terminal can be upper Further blind examination on the basis of information is stated, judges the port number being actually multiplexed, then carries out subsequent data reception and demodulation.Below An example for providing the signaling indexical relation of port number set, is shown in Tables 1 and 2.

The mapping relations of table 1DMRS configuration 1

Instruction	Port number
		0	2
1	4
		2	6

This example is also possible to open based on the data reduction operation carried out on the basis of example one to further decrease signaling Pin, detailed content can be found in foregoing description, and details are not described herein.

In three of the above example (total port number information that base station is multiplexed to users all in the terminal notification scheduling resource), Regardless of how many bit of the port number of terminal notification given, signaling overheads can be brought after all, in the feelings that existing DCI signaling bit is limited Under condition, reduction signaling overheads few as far as possible is needed, so this programme is proposed by MAC-CE (Medium Access Control- Control element, media access control-control unit) carry out semi-static DMRS occupancy symbol numbers notice (also It is to be sent by high-level signaling).There is no the notice signaling expense of total port number in DCI.

If base station has updated DMRS configuration symbols number in scheduling process, relevant information is updated by MAC-CE. There is certain deviation due to operating indicative port number and actual port number according to this, terminal can be in the base of above- mentioned information Further blind examination on plinth, judges the port number being actually multiplexed, and then carries out subsequent data reception and demodulation.

Certainly, in three of the above example, total port number that base station is multiplexed to users all in the terminal notification scheduling resource Information can also be carried out by dedicated Physical Downlink Control Channel, is not limited thereto.

Illustrate herein, in above scheme, as long as the port number indicated with indication signaling, can be taken with signaling bit information The mode that value is incremented by or successively decreases carries out the expression of port number, can also carry out in such a way that any one is appointed；

Such as: the port number for needing to notify be 2,4,6,8 in one of, using 2 bits indicate, then can be with bit 00 It can indicate 2, bit 01 can indicate 4, and bit 10 can indicate 6, and bit 11 can indicate 8, can also be with other sequence lists Show, as long as base station and terminal are appointed in advance.

Furthermore, it is contemplated that in 5G NR system, in order to improve the peak rate of UE, can using multiple transmission point (TRP, Tx/Rx Point), each UE can transmit PDSCH in multiple transmission point simultaneously, and multiple transmission point can be one with simultaneous transmission PDSCH, different transfer points distribute section ports therein, and the port between transfer point does not repeat；In the present embodiment, if currently To the single transmission point that is scheduling to of UE, then according to embodiments of the present invention in scheme described above obtain total port number, if worked as The preceding multiple transmission point that is scheduling to UE, and transmit a PDSCH, then it is obtained respectively according to the port number that multiple transmission point is distributed Respective port number is obtained, acquisition pattern is identical as single scheme of transfer point, is then added the port number of all transfer points, obtains The total port number notified to UE is needed when currently dispatching to UE.

Further, in practical application, base station distributes respective occupancy resource according to the traffic needs of different user, Be possible in this way the port number for occurring being multiplexed in different scheduling resources it is different (for example entire scheduling resource is 100 RBG, Wherein total port number of all user's multiplexings is 6 on preceding 50 RBG, and total port number of all user's multiplexings is on rear 50 RBG 8, then it is different to be just different the port number being multiplexed in scheduling resource), it may be configured using different DMRS.If using whole The mode that a total port number is uniformly notified in a scheduling resource will lead to terminal and be connect using the DMRS configuration progress data of mistake It receives and demodulates；For this problem, following measures are present embodiments provided:

In above scheme description, it is determined that the denoting signaling mode of total port number of multiplexing, and the bit number occupied, This assumes that the bit number occupied is M, and total scheduling resource is divided into X section (the scheduling divided number of resource is X), and there are two types of X Optional Configuration Values { X1, X2 }, each section can notify the corresponding port number of partial scheduling resource；It is accounted for for signaling With the calculation method (and bit indication method) of bit length, it is given below that there are two types of examples, to solve different scheduling resources The port number different problems of multiplexing；

Specific: assuming that M=2, X1=2, X2=3, then the signaling bit length for needing to reserve is 3 × 2=6 bit.

Terminal can independently obtain ratio shared by Downlink Control Information after receiving the Downlink Control Information that base station issues Bit length (determines) according to the rule made an appointment with base station.

Example two:

Base station is chosen from Configuration Values according to the signaling bit length of the actually required occupancy of Downlink Control Information, then accuses Know terminal, can be by increasing by 1 bit signalling, the selection of Lai Tongzhi X:

Such as 1 bit signalling be 0, then represent X=X1,1 bit signalling is 1, then X=X2 is represented, according to the result of practical X It provides actual port number notice and needs reserved signaling bit length.

Specific: assuming that M=2, X1=2, X2=3, if X=X1, the signaling bit length for needing to reserve is 1+2 × 2=5 bit.If X=X2, the signaling bit length for needing to reserve is 1+3 × 2=7 bit.

Terminal can then determine the value of X by directly receiving bit signalling, to carry out subsequent operation.

It is, counterpart terminal side, can pass through implicit indication in example one, such as 6 bits of total bit number, M 2 Bit, then X is exactly 3.It can also be given in advance by the value of 1 bit notification X direct in example two, the eligible value of X.
