Embodiment two:
The physical layer architecture of current NR, where control channel on time-domain symbol position, control channel has usually only taken up part Frequency domain position, the time-frequency domain resources of the available scheduling data traffic of V2X are relatively less, pass through and support control channel and data Channel carry out frequency division multiplexing, be an effective method of raising system spectral efficiency, at this time in order to the data of frequency division multiplexing into Row accurately demodulates, and the demodulated reference signal for demodulating data channel needs new configuration.
In the scene of V2X, sidelink (straight-through link) communication mainly uses the physical layer architecture of uplink, and current In ascending communication system physical layer architecture, control channel will not usually occupy the whole bands distributed in place time-domain symbol position Width, and current NR technology and before Release agreement in, do not support the time-domain symbol where control channel well Upper transmission data service, and the technology how these data services demodulated.Due to control channel, GP (gap) and The presence of reference signal etc. further has compressed the configurable running time-frequency resource position of data service.In order to meet different movements Rate requirement supports the configuration of flexible demodulated reference signal in NR system, utilizes this flexible demodulated reference signal Configuration can also make spectrum efficiency maximize in addition to meeting different movement speeds and requiring.
In order to improve the spectrum efficiency of NR system, the embodiment of the present invention is mainly by the way that vacant running time-frequency resource to be configured to The transmission of data service, such as by unappropriated frequency domain resource is used for the biography of data service on time-domain symbol position where control channel It is defeated, simultaneously because there are the transmission of data service, then how to demodulate at this time to the data of the time-frequency location and how In the case where not making a big impact to demodulation performance, the expense of demodulated reference signal in data channel is reduced
Fig. 2 is referred to, M is equal to 1, N and is equal to 1, and the first demodulated reference signal port is with the second demodulated reference signal port Frequency division multiplexing, there are incidence relations with the second demodulated reference signal port for the first demodulated reference signal port.Namely data channel DMRS be configured to single port, the DMRS of control channel is also configured as single port.
First communication node is closed by the QCL (Quasi Co-Located, the total position of standard) of control channel and data channel System, the parameter configuration of demodulated reference signal in designation date channel, wherein the parameter of demodulated reference signal include at least it is following it One: port number, the incidence relation with control channel demodulated reference signal port, sequence, frequency domain resource position, precoding mode.
Control channel and data channel are there are frequency division multiplexing, the vacant frequency domain resource of time-domain symbol position where control channel On, it is configured to the demodulated reference signal of data channel demodulation.As shown in Fig. 2, when control channel occupies the 3rd, 4,5 at this time Domain sign bit, control channel has only taken up part frequency domain position (eight sons of the upper surface of ordinate in Fig. 1 in these time-domain symbols Carrier wave), in order to improve the utilization rate of resource, other frequency domain positions are configured to transmitting data service.
First communication node configures the demodulated reference signal information of control channel, by QCL relationship designation date channel The relevant configuration of some or all of demodulated reference signal.If the demodulated reference signal of control channel and data channel all configures A port is as shown in Figure 2 equally configured with data channel on the occupied time-domain symbol position of control channel at this time (the 3rd, 4,5 time-domain symbol position ordinate following four subcarrier), it is same to configure for the accuracy of the data channel demodulation Demodulated reference signal for data demodulation.Since there are QCL relationships for control channel and data channel, then it is considered that two The channel of person have very high similarity, so at this time can by the estimated result of the demodulated reference signal of control channel come into The demodulation of row data service.So the precoding of the demodulated reference signal of control channel at this time and the precoding of data channel are phases With.
Embodiment three:
Fig. 3 is referred to, M is equal to 2, N and is equal to 1, and two ports of the first demodulated reference signal are frequency division multiplexing, the first demodulation There are incidence relations with the second demodulated reference signal port for one of port in two ports of reference signal.Namely data Channel DRMS two-port, the DMRS single port of control channel.The DMRS of data channel is frequency division multiplexing.
First communication node configures 2 demodulated reference signal ports in first kind channel resource, 1 in the second class channel resource A demodulated reference signal port, wherein 2 demodulated reference signal ports and the second class channel resource in the first kind channel resource Interior 1 demodulated reference signal port occupies identical time-domain resource.
Control channel is configured using the demodulated reference signal of single port, and data channel uses the demodulated reference signal of multiport Configuration, by taking data channel in Fig. 3 is configured with two demodulated reference signal ports as an example.Control channel is configured with 1 demodulation at this time Reference signal port port2,0, data channel is configured with two port port1,0And port1,1.Time-domain symbol where control channel Position fractional bandwidth is for sending data service, in order to guarantee the accuracy of data channel demodulation, according to current user (including Receiving end) movement speed be configured to data demodulation in some time-domain symbol of time-domain symbol position where control channel Demodulated reference signal, default time-domain position are time-domain position where demodulated reference signal in control channel.
Control channel DMRS and data channel DMRS has the relationship of QCL, then at this time can be in control channel DMRS come assist carry out data channel demodulation, guarantee data channel demodulation accuracy in the case where, can reduce data letter The expense of reference signal in road.But due to being only configured with 1 DMRS port port in control channel2,0, should in order to utilize The DMRS port port of control channel2,0Data channel is demodulated, so needing the DMRS port port in control channel2,0Association A DMRS port, port in data channel1,0Or port1,1.Such as control channel port port under default situations2,0Sum number It is believed that identifying minimum DMRS port port in road1,0With incidence relation, the two precoding information having the same.
The DMRS port port of data channel at this time1,1There is no the DMRS port in control channel associated, data channel DMRS port port1,1It can be sent in the bandwidth of scheduling.In order to avoid data channel DMRS port port1,1Occupied frequency Domain resource, with control channel DMRS port port2,0The frequency domain resource of occupancy collides, and predefines control channel DMRS at this time Port port2,0With the DMRS port port of associated data channel1,0Identical object is needed in identical time-domain symbol position Manage resource location configuration rule, the rule both refers mainly to two kinds of DMRS ports and configures identical multiplex mode and occupied Frequency domain resource configuration.If the differences such as the physical resource position multiplex mode of the occupancy of two kinds of ports, need by first Communication node indicates that control channel relevant information and signal are not configured in control channel, i.e., not used physical resource position. DMRS port port in data channel at this time1,0With port port1,1For frequency division multiplexing, if control channel and data channel are Identical time-frequency domain resources configuration rule, at this time DMRS port port1,1Time-frequency domain resources can occupy entire bandwidth allocation, Including the part frequency domain resource in time-domain symbol where control channel.As shown in Figure 3, data channel DMRS port port1,1Time-domain symbol position (the 4th time-domain symbol) equally in control channel where DMRS is sent.
Example IV:
Fig. 4 is referred to, the embodiment of the present invention has differences on pattern with above-described embodiment three, since DMRS presence can match The time-frequency domain pattern set, it is multiple for frequency division if there is two DMRS ports of data channel even if being directed to different DMRS patterns With then above-mentioned method is equally applicable.By taking Fig. 4 as an example, the DMRS pattern of data channel is the type2 in NR at this time, if Two DMRS ports are frequency division multiplexing, are configurable to DMRS port port1,0With DMRS port port1,2, wherein DMRS port port1,0With the DMRS port port of control channel2,0It is associated, the DMRS port port of data channel1,2Occupy part control letter The time-frequency domain resources in road.
As shown in Figures 3 and 4, for single-carrier system, the DMRS port of two data channels is frequency division, and control at this time The unrelated data channel DMRS port of channel DMRS port processed, i.e. DMRS port port in Fig. 31,1With the DMRS in Fig. 4 Port port1,2, the DMRS sequence of the two generates in entire bandwidth allocation at this time.Different from the DMRS port port in Fig. 31,1 With the DMRS port port1,2, the DMRS port port of data channel in Fig. 41,0The band of occupied bandwidth and above-mentioned two port It is wide different, therefore the sequence of DMRS port 0 is different from other DMRS ports in the same sign bit, the i.e. end DMRS in Fig. 1 DMRS port 2 in 1 and Fig. 2 of mouth.

Embodiment five:
Fig. 5 is referred to, M is equal to 2, N and is equal to 1, and two ports of the first demodulated reference signal are code division multiplexing, the first demodulation One of port and the second demodulated reference signal port in two ports of reference signal are configured to code division multiplexing, the second solution Adjusting reference signal port with another port in two ports of the first demodulated reference signal, there are incidence relations.Namely this One of port of one demodulated reference signal is unrelated to the port of second demodulated reference signal.It is equivalent to data channel DRMS two-port, control channel DMRS single port.The DMRS of data channel is code division multiplexing.
Control channel configures 1 DMRS port, and data channel configures multiple DMRS ports.And the DMRS of data channel at this time There are frequency domain OCC (Orthogonal Cover Code, orthogonal covering codes) between port.
As shown in figure 5, the DMRS port port of data channel at this time1,0With DMRS port port1,1, and the two ports are deposited In frequency domain OCC, such as port port1,0It is demodulated with orthogonal code [1,1], port port1,1It is demodulated with [1, -1].At this time Under default situations, control channel DMRS port port2,0With the DMRS port port of data channel1,0With incidence relation, or By using OCC code be associated.The DMRS of 1 port of configuration in control channel, but DMRS port port2,0Together Sample is demodulated using the frequency domain OCC code of [1,1].Likewise, because the DMRS port port of data channel1,0The port and port1,1Identical time-frequency domain resources are occupied, and the DMRS of control channel is identical with the mapping ruler of data channel DMRS at this time, So the incidence relation of the DMRS port of the DMRS port and data channel of control channel, again may be by frequency domain OCC code Instruction, i.e., the DMRS port of associated control channel and the DMRS port of data channel OCC code having the same.
DMRS port port in data channel1,0With the DMRS port port in control channel2,0With QCL relationship, two Person is associated, then the channel estimation results of control channel can be used to the DMRS port of aid demodulation data channel at this time port1,0.At this time in order to guarantee the demodulation effect of data channel, data channel DMRS port port1,1It needs in control channel institute Configured in the frequency domain that time-domain symbol position is used to send data business (such as in Fig. 54 below 3-5 time-domain symbol A subcarrier), (such as in Fig. 5 3-5 time-domain symbol the upper surface of 8 subcarriers) can also be configured in control channel.At this time The DMRS port port of data channel1,0With port port1,1Has the function of OCC, the two occupies identical running time-frequency resource, and number It is believed that road demodulated reference signal port port1,0With control channel demodulated reference signal port port2,0Physical resource map rule It is then identical, data channel DMRS port port at this time1,1It is mapped in control channel, just will appear control channel port port2,0 With data channel port port1,1Identical running time-frequency resource is occupied, as shown in Figure 5.
In order to guarantee the accuracy of control channel demodulation first, data will be completely removed when carrying out control channel demodulation Channel DMRS port port1,1Interference to control channel.Using OCC characteristic, such as the DMRS port of control channel at this time port2,0Using the OCC code of [1,1], data channel DMRS port port1,1It will be adopted using the OCC code of [1, -1] in demodulation It is added with the subcarrier of OCC demodulation, so that it may remove data channel DMRS port port1,1Influence to control channel.It is corresponding , in order to guarantee data channel DMRS port port1,1Demodulation need to be control channel DMRS when demodulating data channel Primary demodulation will be subtracted each other using the subcarrier of OCC demodulation, remove control channel DMRS port port2,0To the shadow of data channel It rings, guarantees data channel DMSR port port1,1Demodulation effect.
In order to guarantee control channel DMRS port port2,0With data channel DMRS port port1,1Between demodulate it is orthogonal Property, it needs to carry out certain modification to the DMRS sequence producing method of data channel.Wherein can by following two mode come It solves:
1) the DMRS port port of data channel1,0, port port1,1Using with control channel DMRS port port2,0It is identical Sequence producing method.
2) (such as the 3-5 time-domain symbol in Fig. 5 of the data channel frequency domain position where control channel on time-domain symbol position Below four subcarriers) DMRS according to data channel DMRS sequence generate, and control channel where frequency domain position (such as Eight subcarriers of the upper surface of 3-5 time-domain symbol in Fig. 5) DMRS port port1,1Sequence, according to the sequence of control channel Create-rule carries out sequence generation.That is DMRS port port1,1In Fig. 5 on the 4th time-domain symbol position control channel frequency Frequency domain position is (under the 4th time-domain symbol where domain position (eight subcarriers of the upper surface of the 4th time-domain symbol) and data channel 4, face subcarrier) sequence generating mode be different.
Two kinds of sequence generating modes recited above all can be used when system configuration is the waveform of OFDM, have no effect on The use of OCC.But under single carrier waveform, as according to shown in Fig. 5, data channel DMRS port port0,1The port and port1,1It is to be modulated demodulation using OCC, so two ports need identical frequency domain RB when generating DMRS sequence Number, just can guarantee the characteristic of OCC, at this time due to the DMRS port port of data channel in this way1,0With port port1,1The frequency of occupancy Domain resource location is of different sizes, in order to guarantee the OCC function between two DMRS ports of data channel, so in single carrier waveform Under, can only just can guarantee in data channel frequency domain by the above method 2, two DMRS ports can using OCC come into Row modulation and demodulation.DMRS port port in the frequency domain of control channel1,1Sequence and control channel port port2,0It is phase With, so data channel DMRS port port can be eliminated by the characteristic of OCC when demodulating control channel1,1Shadow It rings, when demodulating data channel, control channel port port can be utilized according to OCC characteristic2,0Carry out aid demodulation data channel DMRS port port1,1。
According to previously described control channel DMRS port port2,0With the DMRS port port of data channel1,0With QCL Incidence relation can use control channel DMRS port port2,0To demodulate data channel DMRS port port1,0, and can benefit Data channel DMRS port port is carried out with OCC characteristic auxiliary1,1Demodulation.
