Specific embodiment

Since NR-V2X stage antenna port number purpose increases, the case where for different port numbers, can generate different The mapping mode of reference signal, the reference signal, such as DMRS/ channel state information reference signals (alternatively referred to as detection ginseng Examine signal) (Channel State Information Reference Signal, CSI-RS).When port number increases, reach After certain number, it may be necessary to more OFDM symbols are occupied, so fixed resource impact mode is obviously not suitable for.

In addition, NR-V2X needs receiving end to carry out the feedback of relevant information under certain scenes (unicast mode), these are anti- The information of feedback also needs to carry out resource impact, however LTE-V2X fixed resource impact mode is not these specific letters Reserved mapping position is ceased, therefore can not support feedback function.

Technical solution provided by the embodiments of the present application is using more flexible controllable resource mapping method, to cope with NR- Different situations in V2X select specific region in the region of legacy data mapping and distribute to each specific information, such as DMRS, CSI-RS, channel quality indicate (Channel Quality Indicator, CQI), pre-coding matrix instruction (Precoding Matrix Indicator, PMI), order instruction (Rank Indication, RI), positive acknowledgment (ACK) it is no Fixed confirmation (NACK) etc..

As shown in Figure 1, including 14 OFDM symbols with a RB, and has in a RB and carry out for 4 column DMRS symbols Explanation, it should be noted that feedback information here can be any information for needing receiving end to feed back, and be not limited only to channel shape State information is only for feeding back CSI information herein；The resource mapping position of each information can be, but not limited to position in Fig. 1, Can be more flexible and changeable, specific mapping mode can be controlled by the dispatch that transmitting terminal is sent to receiving end, The columns of DMRS can also carry out adjustment appropriate according to specific scene condition in one RB.When dispatch indicates to need When mapping a certain specific information (such as reference signal and/or feedback information), then advance reservation is just needed to go out resource appropriate Corresponding resource impact is carried out, this section of resource location should be skipped when mapping data at this time.

It should be noted that resource described in the embodiment of the present application, can be time-domain resource, e.g. OFDM symbol is provided Source.Transmitting terminal described in the embodiment of the present application can be network side equipment and be also possible to terminal, described in the embodiment of the present application Receiving end, be also possible to network side equipment or terminal, i.e. transmitting terminal described in the embodiment of the present application and receiving end, be not limited to It is network side equipment or terminal side equipment, technical solution provided by the embodiments of the present application can be applied between network side equipment Transmitting scene, the transmitting scene between terminal, the transmitting scene between network side equipment and terminal.

For NR-V2X system, due to needing to consider that the factor of relative velocity and different frequency range, the application are implemented In example, adaptive adjustment reference signal can be changed according to concrete scene parameter (such as speed and carrier frequency of terminal movement) Density, i.e. OFDM symbol number shared by reference signal.The frequency range that can mainly refer at present has 5.9GHz, 30GHz, 60GHz, It is 30km/h, 120km/h, 280km/h than more typical relative velocity；Since high band transmission range is limited, while frequency deviation It is very big, therefore relatively it is suitble to the scene of relative velocity lower (30km/h).Assuming that in 60GHz frequency range, two user equipmenies (UE) Relative velocity be 30km/h, can calculate channel coherency time at this time is about 253.8us；Assuming that frequency range is 5.9GHz, phase Belong to when being 280km/h to speed than more typical extreme case, channel coherency time at this time is about 276.5us；Each The duration that OFDM symbol occupies is about 60-70us, is at most spaced 4 symbols between two column DMRS, so that it may guarantee estimation letter The accuracy in road；In conclusion at most only needing 4 column DMRS to ensure that the channel under a variety of different scenes in each RB Estimate performance.In practical applications, flexible DMRS density can be configured according to specific circumstances, can both guarantee that channel is estimated The accuracy of meter, and can reduce the expense that reference signal occupies data.

The dispatch provided in the embodiment of the present application can indicate to need different port number in NR-V2X different Reference signal mapping mode etc. further also can indicate that and need the correlations such as receiving end feedback information under specific transmission mode Content.

For example, the dispatch provided in the embodiment of the present application may include as follows by taking feeding back channel state information as an example One or more information field:

1) CSI-RS status signaling: it is used to refer to whether current subframe needs to send CSI-RS；

2) reference signal maps indication signaling: for example, indicating the resource impact position of DMRS and/or CSI-RS according to port number It sets.Wherein the resource mapping position information of CSI-RS only (needs to send CSI-RS's in CSI-RS status signaling open state In the case of) under just effectively；

3) it CSI-request signaling (i.e. the request of feedback information): is used to indicate receiving end and carries out channel state information Feedback；

4) channel state information (Channel State Information, CSI) dispatch (the i.e. tune of feedback information Degree instruction): for when receiving end feeding back channel state information, indicating how scheduling tri- information of CQI, RI, PMI etc.；Wherein, For CSI dispatch, if tri- information of CQI, PMI, RI of feedback are mapped in data symbol with fixed position, So this mode can reduce the expense of CSI dispatch, only need to indicate respectively whether feed back these types of information i.e. at this time Can, do not need the information such as instruction mapping position；In addition, CSI dispatch can also be by the way of on-fixed mapping position, this When need to indicate the information of specific resource mapping position, but this mode for signaling scheduling more flexibly.

In addition, it is necessary to explanation, port described in the embodiment of the present application refers both to antenna port (port).

The illustration of several specific embodiments is given below.

Embodiment 1:

Functional block diagram in embodiment 1 carries out scheme explanation, the present embodiment master for including 3 column DMRS in a RB Illustrate reference signal caused by NR-V2X antenna port number increases using different resource impact mode and is likely to occur Situation, wherein DMRS is mapped in OFDM symbol in the form of pectination, and CSI-RS is interspersed to be mapped to the vacant resource location of DMRS. The port number that CSI-RS is occupied is greater than or equal to DMRS port number.The present embodiment is by taking the DMRS maximum port number supported is 8 as an example.

In addition, needing to guarantee that the density of resource impact is at least each PORT and at least reflects on each RB for CSI-RS Penetrate a RE；Due to the port number that the CSI-RS port number occupied would generally be occupied more than DMRS, successively using CSI-RS It is mapped to the mapping mode of the vacant resource outside the resource of DMRS occupancy, the port number requirement for needing to occupy until meeting CSI-RS , in order to facilitate the control of CSI-RS resource mapping position, the port number that CSI-RS is occupied can choose 2 power number；

Being left rest resource for DMRS pectinate texture can choose transmission data, or carries out interference using it and disappear Except promotion receiver performance；

It both can be in such a way that the period have sent or using aperiodic sending method for CSI-RS；

The case where for not needing mapping CSI-RS resource, give the following pattern3 and pattern4 for supporting to retract Both of which can save the expense of dispatch using the pattern of this fixation.

The signal transmitted between pattern described in the embodiment of the present application, i.e. transmitting terminal and receiving end is in every RB Resource impact mode or resource mapping method embody the transmission money that the signal transmitted between transmitting terminal and receiving end needs to occupy Source.

The various pattern provided in the embodiment of the present application, can be by the way of protocol conventions, in transmitting terminal and reception It pre-sets, can also be arranged by network side and is notified to terminal in end, specific set-up mode does not limit.

Alternatively, various pattern can not also be preset in the embodiment of the present application in transmitting terminal and receiving end, but One or more calculation formula are previously provided with, transmitting terminal is determined in conjunction with calculation formula by the information carried in dispatch The signal transmitted between receiving end needs the transfer resource occupied.Specific calculation formula, in the embodiment of the present application without It limits, can be decided according to the actual requirements.In the embodiment of the present application, is mainly sent and be used to indicate to receiving end by transmitting terminal Receiving end determines the dispatch for the transfer resource that the signal transmitted between transmitting terminal and receiving end needs to occupy, to realize flexibly Resource impact instruction, specifically, how transmitting terminal determines what the signal that transmits between transmitting terminal and receiving end needed to occupy How transfer resource and receiving end, which pass through dispatch, determines what the signal transmitted between transmitting terminal and receiving end needed to occupy Transfer resource can according to need there are many implementation, and the application is without limiting.

Above scheme does not represent final NR-V2X reference signal mapping scheme, only carries out scheme explanation as example.This Shen Please embodiment provide specific pattern be described below:

Pattern1: referring to fig. 2, it is 1 that each column DMRS, which occupies OFDM symbol number: it uses 2-FD-OCC (adjacent frequency domain RE), Maximum is supported to the DMRS for occupying 2 ports.CSI-RS uses 2-FD-OCC (adjacent frequency domain RE), can support to occupy over 2 The channel measurement of a port.

Pattern2: referring to Fig. 3, it is 2 that each column DMRS, which occupies OFDM symbol number: using combination (Combination, comb) + cyclic shift (cyclic shifts, CS) 2 modes (or 2-FD-OCC)+TD-OCC ({ 1,1 } and { 1, -1 }), maximum are supported to arrive Occupy the DMRS of 8 ports；CSI can support the channel measurement more than 8 ports using 2-TD-OCC (adjacent time domain RE)；It is right In more than the channel measurement of 8 ports the case where, the gap resource that need to only continue in the resource for occupying secondary series DMRS is whole The channel measurement of 16 ports can be supported by being mapped to CSI-RS signal；Wherein, TD-OCC ({ 1,1 } and { 1, -1 }) indicates two It is multiplexed between port using time domain orthogonal overlay code (TD-OCC), { 1,1 } { 1, -1 } is the multiplexing coefficient of two ports respectively.

Wherein, wherein comb be exactly between frequency domain multiplexing, such as port 0 and 2 comb2 multiplexing relationship.CS2 is port Between sequence be multiplexed using cyclic shift mode (cyclic shifts), for example be exactly answering for CS2 between port 0 and 1 With relationship.

Wherein, TD-OCC is time domain orthogonal overlay code (Orthogonal Cover Code, OCC) multiplexing.

Pattern3: referring to fig. 4, existing due in certain scenes, still will use single port or transmission diversity (TxD) etc. Some V2X transmission modes, only need to send DMRS at this time, and no need to send CSI-RS, therefore retain the resource of existing DMRS Mapped mode, DMRS symbolic number is 1, and by the way of CS2, maximum supports that occupying port number is 2；

Pattern4: referring to Fig. 5, port number is more in order to cope with, and the open loop for not needing feeding back channel state information passes Defeated mode, DMRS symbolic number is 2 at this time, maximum using comb+CS2 (or 2-FD-OCC)+TD-OCC ({ 1,1 } and { 1, -1 }) The DMRS for occupying 8 ports is supported (to be equivalent to the mapping that pattern2 eliminates CSI-RS, whole resources are used to be mapped to DMRS sequence).

The embodiment that the embodiment of the present application is enumerated is to carry out proof explanation for having 3 column reference signals in a RB, Actual conditions should can be with flexible configuration；1 port is wherein schematically illustrated respectively, the case where 2 ports, 4 ports and 8 port.
