Description

A kind of transmission method of Downlink Control Information, base station, terminal and storage medium

Technical field

The present invention relates to field of communication technology, particularly relate to the transmission method of Downlink Control Information a kind of, base station, terminal and Computer readable storage medium.

Background technique

Extensive antenna system MU-MIMO (Multi-User Multiple-Input Multiple-Output, Multi-user multiple input multiple output technology) in the data fluxion of simultaneous transmission can greatly improve.Currently, user can lead in LTE system It crosses dedicated DMRS (DeModulation Reference Signal, demodulated reference signal) and carries out channel estimation, wherein DMRS Signal executes pre-encode operation identical with data-signal.To DCI (the Downlink Control of terminal notification Information, Downlink Control Information) pass through PDCCH (Physical Downlink Control Channel, physical down Control channel) it transmits, DCI is not need shared DCI between different user based on user.

After 5G newly eats dishes without rice or wine (NR:New Radio) project initiation, in order to reduce processing delay, lifting system performance, weight Newly DMRS pilot tone pattern is designed and defined.In new DMRS pilot tone pattern, there are many different pilot tone patterns.Tool Body configuration is as follows:

Configuration (configuration) 1:

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

(1) see Fig. 1 (could support up 4 antenna port antenna port), wherein comb2 is frequency domain multiplexing, for example is held It is exactly the multiplexing relationship of comb2 between mouth 0 and 2.Sequence of the CS2 between port uses cyclic shift mode (cyclic Shifts it) is multiplexed, for example is exactly the multiplexing relationship of CS2 between port 0 and 1.

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

(2) see Fig. 2 (could support up 8 antenna ports), TD-OCC be time domain OCC (Orthogonal Cover Code, Orthogonal code) multiplexing, for example be multiplexed between port 0/1 and 4/5 using time domain OCC.

Configuration 2

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

(1) see Fig. 3 (could support up 6 antenna ports), 2-FD-OCC, i.e. frequency domain OCC multiplexing, such as between port 0 and 1 It is exactly frequency domain OCC multiplexing.In addition using FDM (Frequency Division Multiplexing, frequency between other ports Division multiplexing) FDM mode is used between mode, such as 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 Fig. 4 (could support up 12 antenna ports), TD-OCC is time domain OCC (Orthogonal Cover Code) Multiplexing, for example be multiplexed between port 0/1 and 6/7 using time domain OCC.

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. 1, if it exceeds 4, but 8 are no more than, it can be with Fig. 2's Pattern is configured；The case where configuration2, can be with Fig. 3'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. 4.Port number in this is Refer to the port number summation for all users being multiplexed on the resource location.

In order to support correct demodulation of the user at MU-MIMO, need useful to institute in each scheduling resource of terminal notification The total port number information in family.The information is all identical for the user of all MU-MIMO in the scheduling resource, so if Information transmission is carried out based on the PDCCH of user, the user to all MU-MIMO is needed all to transmit by respective PDCCH, It will lead to the waste of system resource.

That is, for the pattern of the determining various configurations of DMRS, in MU-MIMO, on different running time-frequency resources, The number of users of multiplexing is different, then the DMRS port number that there is concurrent multiplexing in different resources is different, according to existing DMRS configuration information, different port numbers may use different DMRS pilot tone patterns.But the information (pilot tone pattern) is right It for the user of all MU-MIMO is all identical in the scheduling resource, so if carrying out information based on the PDCCH of user Transmission, needs the user to all MU-MIMO all to transmit by respective PDCCH, will lead to the waste of system resource.

Be directed to Downlink Control Information includes situation, and the embodiment of the present invention provides two schemes for step 61:

The first, it is described when the Downlink Control Information includes partial information needed for this terminal receives and solves adjusting data It include: by organizing public object by the step of organizing public Physical Downlink Control Channel, receiving the Downlink Control Information that base station issues Down control channel is managed, the periodical information in the Downlink Control Information that the base station issues is received；Wherein, the periodically letter Breath include the first preset time period in multiple-input, multiple-output multiplexing total port number the first average value or with total port number pair Second average value of the demodulated reference signal configuration information answered；First average value and the second average value are for number Average value.

Specifically, it is described by organizing public Physical Downlink Control Channel, receive the Downlink Control Information that the base station issues In periodical information the step of include: that institute is received according to the first public Physical Downlink Control Channel of preset time period monitoring group State the periodical information in the Downlink Control Information that base station issues；Alternatively, passing through the public physical down control letter of lasting blind examination group Road receives the periodical information in the Downlink Control Information that the base station issues.

Further, the transmission method further include: by dedicated Physical Downlink Control Channel corresponding with this terminal, connect Receive the deviation information that the base station issues；Wherein, the deviation information be prompting message when this terminal dispatches resource every time with Deviation information between the periodical information.

Wherein, described the step of carrying out data receiver and demodulation according to the Downlink Control Information includes: according to described the One average value and the deviation information, obtain this terminal it is corresponding it is each scheduling resource when multiple-input, multiple-output multiplexing total port number； Or according to second average value and the deviation information, demodulation reference when the corresponding each scheduling resource of this terminal is obtained Signal configuration information；According to total port number or demodulated reference signal configuration information, data receiver and demodulation are carried out.

It is second, described when the Downlink Control Information includes all information needed for this terminal receives and solves adjusting data It include: by organizing public object by the step of organizing public Physical Downlink Control Channel, receiving the Downlink Control Information that base station issues Manage down control channel, receive in the Downlink Control Information that issues of base station total port number of multiple-input, multiple-output multiplexing or with it is described total The corresponding demodulated reference signal configuration information of port number (it can be real-time reception, be also possible to based on instruction or demand etc. receives, It is not limited thereto；Received information can substantially be the index of total port number or demodulated reference signal configuration information).

Specifically, it is described by organizing public Physical Downlink Control Channel, it receives more in the Downlink Control Information that base station issues The step of entering to have more the total port number or demodulated reference signal configuration information corresponding with the total port number of multiplexing includes: logical The persistently public Physical Downlink Control Channel of blind examination group is crossed, multiple-input, multiple-output multiplexing is total in the Downlink Control Information that reception base station issues Port number or demodulated reference signal configuration information corresponding with the total port number.

Further, it by the public Physical Downlink Control Channel of group, receives more in the Downlink Control Information that base station issues Before the total port number or demodulated reference signal configuration information corresponding with the total port number that enter to have more multiplexing, the transmission Method further include: receive the monitoring instruction that base station issues；

It is corresponding, it is described by organizing public Physical Downlink Control Channel, it receives more in the Downlink Control Information that base station issues The step of entering to have more the total port number or demodulated reference signal configuration information corresponding with the total port number of multiplexing includes: root Public Physical Downlink Control Channel is monitored in the second preset time period according to monitoring instruction, receives the downlink control that base station issues The total port number or demodulated reference signal configuration information corresponding with the total port number that multiple-input, multiple-output are multiplexed in information processed.

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 current 5G newly eats dishes without rice or wine under (NR:New Radio), it is available that there are two types of PDCCH, and one is organize public PDCCH (group common PDCCH), one is the dedicated PDCCH of user (UE specific PDCCH).User is based on certain by NR Principle is divided into multiple groups, for example is based on wave beam forming direction, and every group can send the public PDCCH of group, organize at present public PDCCH only supports the period can be with transmission.The public PDCCH of UE periodicity monitoring group.The PDCCH of user dedicated PDCCH and LTE system Sending method is identical, is needed that PDCCH can be sent at any time according to scheduling.

Need PDCCH transmit related DMRS configuration DCI information include multiple RBG (Resource Block Group, Resource block group) port number in resource or DMRS configuration information and this user matched based on the DMRS in each scheduling resource Confidence breath.

Wherein DMRS configuration information can define an allocation list, configure the various of DMRS to terminal by lookup table mode Configuration information, for example include port number, port numbering, FDM (frequency division multiplex), CS (cyclic shift), OCC and total Port number (or the total port number range that can be supported), power offset (power bias) etc..

If in DMRS allocation list, the value of total port number of a certain MU-MIMO multiplexing, corresponding DMRS configuration index Index, then terminal can be allowed to obtain the information by way of to the total port number of terminal notification (can from Fig. 1 to Fig. 4 Out, in the case where different total port numbers, corresponding DMRS configuration is different, and the resource for referring specifically to DMRS configuration occupancy is different, than As occupied one or two OFDM symbols).

If in DMRS allocation list, the value of total port number of a certain MU-MIMO multiplexing, corresponding multiple DMRS configurations Index then cannot allow terminal to obtain the information by way of to the total port number of terminal notification, can be by giving terminal notification Total port number obtains corresponding DMRS and configures index, which is notified to terminal.

In conjunction with the above content, in view of the above technical problems, the embodiment of the invention provides a kind of biographies of Downlink Control Information Transmission method can specifically include that (information transmitted in example can configure following several examples for total port number or DMRS Index can support that difference is exactly overhead bit difference):

Example one:

Periodical information is transmitted using public PDCCH (Physical Downlink Control Channel) is organized, is indicated as the first order, such as Total port number (total port number of multiple-input, multiple-output multiplexing) of a period of time or the average value of its corresponding DMRS configuration information, make With the prompting message dispatched every time of the dedicated PDCCH of user (the corresponding dedicated Physical Downlink Control Channel of terminal) transmission opposite the The DMRS configuration information of the difference of level-one beacon information, the i.e. second level mark and this user.For example, the first order is denoted as P0, The second level is denoted as deltaP, and wherein P0 is the average information in cycle T, and deltaP is each thread time in cycle T Information and P0 difference.

Since the public PDCCH of group is while can notify to compare to multiple terminals with dedicated PDCCH, cost reduction, also It is that the scheme of example one transmits a mean information by using public PDCCH is organized, dedicated PDCCH provides difference, relative to DMRS configuration information is directly transmitted, transport overhead can be reduced.

Example two:

Total port number or its corresponding DMRS configuration information are transmitted using public PDCCH is organized, uses the dedicated PDCCH of user Transmit the DMRS configuration information (the DMRS configuration information of this user) of this user actual schedule.Only due to existing group of public PDCCH Periodicity sending mode is supported, so can pass through if total port number or its corresponding DMRS configuration information change The mode of event triggering triggers the base station public PDCCH of transmission group, i.e., by total port number or its corresponding DMRS with confidence Whether breath changes as trigger condition, to trigger the base station public PDCCH of transmission group (event are as follows: total port number or its correspondence DMRS configuration information change, whether base station oneself changes according to the information, to determine whether sending dedicated PDCCH).And Terminal can have following two to the listening mode for organizing public PDCCH:

The first, the function that can be indicated by increasing 1bit on the dedicated PDCCH of user, Lai Tongzhi terminal needs to receive The public PDCCH of group is (when determination needs the public PDCCH of transmission group, it is necessary to whether providing for dedicated PDCCH sent the last The information of 1bits indicates, terminal is told to need the public PDCCH of horse back monitoring group)；If information is 1: then public in group The public PDCCH of reception group is searched in PDCCH resource, if information is 0: not needing except the group public PDCCH period receives Time receives the public PDCCH of group；

It second, allows the terminal public PDCCH of blind examination group always, is not by the dedicated public PDCCH of PDCCH key group of user No transmission.
