Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the embodiments of the present invention is given with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Embodiment one:

in an NR (New Radio) system, the configuration of the demodulation reference signal is flexible, and the configuration of the demodulation reference signal may be different in different scenarios. For example, in some scenarios where the user is low speed, the configuration of the demodulation reference signal in the data channel may occupy a smaller number of time domain symbols in the configuration of one transmission subframe or non-subframe structure. In some high-speed mobile scenarios, more time domain symbols may be required to transmit the demodulation reference signal in the data channel, so as to effectively reduce the problem of inaccurate demodulation caused by high-speed mobile, which necessarily results in an increase of the overhead of the demodulation reference signal.

Based on this, the embodiment of the invention provides a demodulation reference signal processing method, which improves the accuracy of channel demodulation under the condition of ensuring that the overhead of the demodulation reference signal is not increased. Referring to fig. 1, the demodulation reference signal processing method mainly includes the following steps:

s101, obtaining physical resources to be configured, wherein the physical resources to be configured comprise first-type channel resources and second-type channel resources.

S102, configuring M first demodulation reference signal ports for first-class channel resources, and configuring N second demodulation reference signal ports for second-class channel resources; the first demodulation reference signal is used for demodulating the first type of channel resources, the second demodulation reference signal is used for demodulating the second type of channel resources, and the first demodulation reference signal port and the second demodulation reference signal port have an association relation.

Optionally, the physical resources to be configured include RBs (Resource blocks), and allocated bandwidths.

Optionally, the first type of channel resources include time-frequency domain resources where the data channel is located, and the second type of channel resources include time-frequency domain resources where the control channel is located. The control channels include PSCCH (Physical Sidelink Control Channel physical direct link control channel), PUCCH (Physical Uplink Control Channel, physical layer uplink control channel), PDCCH (Physical Downlink Control Channel, physical layer downlink control channel), and the like, and the data channels include PSSCH (Physical Sidelink Shared Channel physical direct link shared channel), PUSCH (Physical Uplink Shared Channel, physical layer uplink shared channel), PDSCH (Physical Downlink Shared Channel, physical layer downlink shared channel), and the like.

Optionally, when the first type of channel resources are time-frequency domain resources where the data channel is located, and the second type of channel resources are time-frequency domain resources where the control channel is located, the first demodulation reference signal is a demodulation reference signal for demodulating the data channel, and the second demodulation reference signal is a demodulation reference signal for demodulating the control channel.

In the embodiment of the invention, M is greater than or equal to 0, N is greater than or equal to 0, and both are integers. For example, m=1, 2, 3, … …, n=1, 2, 3, 4, … ….

Optionally, the configuration M is equal to N, that is, the number of the first demodulation reference signal ports is equal to the number of the second demodulation reference signal ports. For example, m=1, n=1; or m=2, n=2.

In the embodiment of the invention, the first demodulation reference signal port and the second demodulation reference signal port have an association relationship. Wherein the association relationship includes at least one of: quasi Co-Located (QCL for short), identical sequences, identical precoding matrix, identical orthogonal cover codes (Orthogonal Cover Code, OCC for short). For example, if the first demodulation reference signal port and the second demodulation reference signal port are configured to have quasi co-location, it is indicated that the first demodulation reference signal port and the second demodulation reference signal port have association relation; or the first demodulation reference signal port and the second demodulation reference signal port are configured to have the same sequence, and the association relation between the first demodulation reference signal port and the second demodulation reference signal port can be also illustrated; or the first demodulation reference signal port and the second demodulation reference signal port are configured to have the same precoding matrix, and the association relationship between the first demodulation reference signal port and the second demodulation reference signal port can also be illustrated; or the first demodulation reference signal port and the second demodulation reference signal port are configured to have the same OCC code, which can also indicate that the association relationship exists between the first demodulation reference signal port and the second demodulation reference signal port.

The first demodulation reference signal and the second demodulation reference signal are identical, which can be expressed as that the port sequences associated with the two are intercepted or generated in the same way, or the base sequences are identical, or the sequence of the first demodulation reference signal is regarded as the continuation of the second demodulation reference signal on the subcarrier where the first demodulation reference signal is located.

Optionally, the association relationship may be indicated by indication information, where the indication information includes at least one of: quasi co-location relationship of the first demodulation reference signal port and the second demodulation reference signal port, sounding reference signal resource identifier (Sounding reference signal Resource Indicator, abbreviated as SRI), and transmission precoding matrix identifier (Transmission Precoding Patrix Indicator, abbreviated as TPMI).

Taking configuration of 2 first demodulation reference signal ports and 2 second demodulation reference signal ports as an example, it is assumed that these 2 first demodulation reference signal ports are respectively ports _1，0 、port _1，1 The 2 second demodulation reference signal ports are respectively ports _2，0 、port _2，1 . First demodulation reference signal port _1，0 And a second demodulation reference signal port _2，0 An association relationship exists, and the two have quasi-co-location relationship; further, the first demodulation reference signal port can be configured _1，1 And a second demodulation reference signal port _2，1 There is an association relationship, and the two have quasi co-positional relationship.

Optionally, the first demodulation reference signal port P _1i And a second demodulation reference signal port P _2j There is an association, i.e. one of the demodulation reference signals configuring the channel resources of the first type (first demodulation reference signal port P _1i ) With one of the demodulation reference signals of the second type of channel resources (second demodulation reference signal port P _2j ) There is an association relationship.

Optionally, the default configuration i is equal to the j, that is, the default configuration port identifiers (i and j) have an association relationship between two identical demodulation reference signals (one of the first demodulation reference signal ports and one of the second demodulation reference signal ports).

Optionally, the plurality of ports of the first demodulation reference signal are configured as frequency division multiplexing or code division multiplexing.

Optionally, the plurality of ports of the second demodulation reference signal are configured as frequency division multiplexing or code division multiplexing.

Optionally, the indication information indicates that the enabling relationship between the first demodulation reference signal port and the second demodulation reference signal port is configured at one time domain symbol position, and the indication information includes at least one of the following: quasi co-location relation of the first demodulation reference signal port and the second demodulation reference signal port, high-layer signaling and dynamic signaling, wherein the first demodulation reference signal and the second demodulation reference signal use the same transmission precoding matrix identification. The enabling relationship refers to whether or not there is a presence, here whether or not two DMRS are supported to be simultaneously configured on the same time domain symbol.

In the NR system, no matter a single carrier is used or OFDM (Orthogonal Frequency Division Multiplexing ) is used, only control channel related information is transmitted on time domain symbol bits occupied by a control channel, and no data service related content is transmitted. And thus is a low utilization of resources for the transmission efficiency of data traffic.

Optionally, at least one first demodulation reference signal port is configured to be located within the second type of channel resources. The empty resources in the second type of channel resources are effectively utilized, the resource utilization rate is improved, and the demodulation accuracy of the first type of channel resources is improved.

In other examples of the present invention, at least one first demodulation reference signal port may be configured to be located at a frequency domain position on a time domain symbol where a second demodulation reference signal is located in the second type of channel resource. Alignment of demodulation reference signals in the second type of frequency domain resources is achieved.

Optionally, the first demodulation reference signal port located in the second type of channel resource selects its sequence based on the frequency domain bandwidth of the second type of channel resource.

Optionally, the sequence generating manner of the first demodulation reference signal port located in the second type of channel resource is the same as the sequence generating manner of the second demodulation reference signal port.

Optionally, at least one first demodulation reference signal port is configured to be located in the first type of channel resources, and the first reference signal port located in the first type of channel resources is selected to be the sequence based on the frequency domain bandwidth of the first type of channel resources.

Optionally, before configuring M first demodulation reference signal ports for the first type of channel resources, a current position movement rate of the second communication node is obtained, and it is determined that the current movement rate is greater than a preset movement rate. The second communication node is a communication node serving as a receiving end, and includes, but is not limited to, a vehicle-mounted terminal, a user terminal, roadside equipment, a base station and the like.

Optionally, after the physical resource to be configured is configured, a configured physical resource is formed, and the configured physical resource is sent to the second communication node.

Embodiment two:

in the current physical layer structure of NR, the control channel occupies only part of the frequency domain position, and the time-frequency domain resources of the scheduled data service available for V2X are relatively less, so that the method is an effective method for improving the frequency domain efficiency of the system by supporting the control channel and the data channel for frequency division multiplexing, and at this time, in order to accurately demodulate the frequency division multiplexed data, a new configuration is required for demodulating the demodulation reference signal of the data channel.

In the V2X scenario, the uplink (direct link) communication mainly adopts an uplink physical layer structure, while in the current uplink communication system physical layer structure, the control channel generally does not occupy the whole allocated bandwidth at the time domain symbol position, and in the current NR technology and the previous Release protocol, there is no good support for transmitting data services on the time domain symbol where the control channel is located, and how to demodulate the data services. Due to the existence of control channel, GP (gap), reference signal, etc., the configurable time-frequency resource location of data traffic is further compressed. In order to meet different mobile rate requirements, flexible demodulation reference signal configuration is supported in an NR system, and the frequency spectrum efficiency can be maximized by utilizing the flexible demodulation reference signal configuration besides meeting different mobile speed requirements.

In order to improve the spectrum efficiency of the NR system, the embodiment of the present invention mainly configures the vacant time-frequency resource for transmission of the data service, for example, uses the unoccupied frequency domain resource on the time domain symbol bit where the control channel is located for transmission of the data service, and meanwhile, because there is transmission of the data service, how to demodulate the data at the time-frequency position? And how does the overhead of demodulating reference signals in the data channel be reduced without significantly affecting demodulation performance?

Referring to fig. 2, m is equal to 1, n is equal to 1, the first demodulation reference signal port and the second demodulation reference signal port are frequency division multiplexed, and there is an association relationship between the first demodulation reference signal port and the second demodulation reference signal port. That is, the DMRS of the data channel is configured as a single port, and the DMRS of the control channel is also configured as a single port.

The first communication node indicates a parameter configuration of a demodulation reference signal in a data channel through a QCL (Quasi Co-Located) relationship of a control channel and the data channel, wherein the parameter of the demodulation reference signal at least comprises one of the following: the association relation between the port number and the control channel demodulation reference signal port, the sequence, the frequency domain resource position and the precoding mode.

The control channel and the data channel have frequency division multiplexing, and demodulation reference signals for data channel demodulation are configured on empty frequency domain resources of time domain symbol bits where the control channel is located. As shown in fig. 2, the control channel occupies the 3 rd, 4 th and 5 th time domain symbol positions, and on these time domain symbols, the control channel occupies only part of the frequency domain positions (the upper eight subcarriers of the ordinate in fig. 1), and other frequency domain positions are configured to transmit data traffic in order to improve the utilization rate of resources.

The first communication node configures demodulation reference signal information of the control channel, and indicates relevant configuration of part or all demodulation reference signals in the data channel through the QCL relation. If the demodulation reference signals of the control channel and the data channel are both configured with one port, as shown in fig. 2, the data channel (four subcarriers below the ordinate of the 3 rd, 4 th and 5 th time domain symbol bits) is also configured on the time domain symbol bits occupied by the control channel, and for the accuracy of demodulation of the data channel, the demodulation reference signal for data demodulation is also configured. Since the control channel and the data channel have QCL relationship, the channels of the control channel and the data channel can be considered to have high similarity, so that the demodulation of the data service can be performed through the estimation result of the demodulation reference signal of the control channel. The precoding of the demodulation reference signal of the control channel and the precoding of the data channel are the same at this time.

Embodiment III:

referring to fig. 3, m is equal to 2, n is equal to 1, two ports of the first demodulation reference signal are frequency division multiplexed, and one of the two ports of the first demodulation reference signal has an association relationship with the second demodulation reference signal port. Namely, two ports of a data channel DRMS and a single port of a DMRS of a control channel. The DMRS of the data channel is frequency division multiplexed.

The first communication node configures 2 demodulation reference signal ports in the first type of channel resources and 1 demodulation reference signal port in the second type of channel resources, wherein the 2 demodulation reference signal ports in the first type of channel resources and the 1 demodulation reference signal port in the second type of channel resources occupy the same time domain resources.

The control channel is configured by a single-port demodulation reference signal, the data channel is configured by a multi-port demodulation reference signal, and two demodulation reference signal ports are configured by the data channel in fig. 3. At this time, the control channel is configured with 1 demodulation reference signal port _2,0 The data channel is configured with two ports _1,0 And port _1,1 . The partial bandwidth of the time domain symbol position of the control channel is used for transmitting data service, in order to ensure the demodulation accuracy of the data channel, according to the current moving speed of the user (including the receiving end), a demodulation reference signal used for data demodulation is configured on a certain time domain symbol of the time domain symbol position of the control channel, and the default time domain position is the time domain position of the demodulation reference signal in the control channel.

The control channel DMRS and the data channel DMRS have a QCL relationship, so that demodulation of the data channel can be assisted by the DMRS in the control channel, and the overhead of the reference signal in the data channel can be reduced under the condition of ensuring the demodulation accuracy of the data channel. But since only 1 DMRS port is configured in the control channel _2,0 DMRS port for enabling use of the control channel _2,0 Demodulating the data channel, the DMRS port in the control channel is required _2,0 Associated with one DMRS port in a data channel，port _1,0 Or port _1,1 . For example control channel port by default _2,0 And DMRS port with lowest identification in data channel _1,0 Has an association relationship, and the two have the same precoding information.

DMRS port of data channel at this time _1,1 Without DMRS port association in control channel, data channel DMRS port _1,1 May be transmitted over a scheduled bandwidth. To avoid DMRS port of data channel _1,1 Occupied frequency domain resource and control channel DMRS port _2,0 Collision of occupied frequency domain resources occurs, and DMRS port of control channel at the moment is predefined _2,0 DMRS port of associated data channel _1,0 The same physical resource position configuration rule is needed at the same time domain symbol position, and the rule mainly refers to the configuration of the same multiplexing mode and occupied frequency domain resource for two DMRS ports. If the occupied physical resource position multiplexing modes of the two ports are different, the first communication node needs to indicate that the control channel related information and signals are not configured in the control channel, namely the unused physical resource positions. DMRS port in the data channel at this time _1,0 And port _1,1 For frequency division multiplexing, if the control channel and the data channel are the same time-frequency domain resource allocation rule, the DMRS port _1,1 The time-frequency domain resources of (a) may occupy the entire allocated bandwidth, including a portion of the frequency domain resources on the time-domain symbol where the control channel is located. As shown in fig. 3, the data channel DMRS port _1,1 Also, the time domain symbol bit (4 th time domain symbol) where the DMRS is located in the control channel is transmitted.

Embodiment four:

referring to fig. 4, the embodiment of the present invention is different from the third embodiment in pattern, and because the DMRS has a configurable time-frequency domain pattern, even for different DMRS patterns, if two DMRS ports where a data channel exists are frequency division multiplexed, the method described above is equally applicable. Taking fig. 4 as an example, when the DMRS pattern of the data channel is type2 in NR, if two DMRS ports are frequency division multiplexed, the DMRS port por may be configured as followst _1,0 And DMRS port _1,2 Wherein DMRS port _1,0 And DMRS port of control channel _2,0 Associated, DMRS port of data channel _1,2 Occupying part of the time-frequency domain resources of the control channel.

As shown in fig. 3 and 4, for a single carrier system, the DMRS ports of the two data channels are frequency division, and the DMRS ports of the data channels not associated with the DMRS ports of the control channels, i.e., the DMRS ports in fig. 3 _1,1 And DMRS port in fig. 4 _1,2 The DMRS sequences of both are generated throughout the allocated bandwidth at this time. Unlike DMRS port in fig. 3 _1,1 And DMRS ports port1,2 in fig. 4, DMRS port of data channel _1,0 The occupied bandwidth is different from the bandwidths of the two ports, so that the sequence of DMRS port 0 is different from other DMRS ports in the same symbol bit, i.e., DMRS port1 in fig. 1 and DMRS port 2 in fig. 2.

The first communication node indicates the enabling relation of simultaneously configuring the first demodulation reference signal and the second demodulation reference signal at one time domain symbol position, and the indication information is at least one of the following: quasi co-location relationship of the first demodulation reference signal port and the second demodulation reference signal, high-layer signaling and dynamic signaling.

I.e., if there is a QCL relationship between the two, demodulation reference signals for demodulating the data channel can be configured on the time domain symbols of the data channel and the control channel frequency division multiplexing. The first communication node may indicate whether the demodulation reference signals of the control channel and the data channel are configured on the same time domain symbol by higher layer signaling, for example, by RRC (Radio Resource Control ) signaling, MAC CE (Media Access Control control element, medium access control element) signaling, or whether frequency division multiplexing of the demodulation reference signals of the data channel and the control channel is present.

The first communication node indicates the enabling relation of the data channel demodulation reference signal port in the time domain symbol position which is frequency division multiplexed with the control channel demodulation reference signal port through the quasi-co-position relation of the control channel demodulation reference signal port and the data channel demodulation reference signal port. I.e., if there is a QCL relationship between the two, demodulation reference signals for demodulating the data channel can be configured on the time domain symbols of the data channel and the control channel frequency division multiplexing.

The first communication node indicates the enabling relation of the data channel demodulation reference signal port at the time domain symbol position which is frequency division multiplexed with the control channel through signaling, wherein the signaling can be high-layer signaling or dynamic signaling, and the dynamic signaling comprises SCI (Sidelink Control Information, through link control information), DCI (Downlink Control Information ).

The first communication node indicates the enabling relation of the demodulation reference signal port of the data channel in the time-frequency domain resource where the control channel is located through signaling, namely, part or all of demodulation reference signals are configured on the time-frequency domain resource position occupied by the control channel.

Fifth embodiment:

referring to fig. 5, m is equal to 2, n is equal to 1, two ports of the first demodulation reference signal are code division multiplexed, one of the two ports of the first demodulation reference signal and the second demodulation reference signal port are configured as code division multiplexed, and the second demodulation reference signal port has an association relationship with the other of the two ports of the first demodulation reference signal. I.e. one of the ports of the first demodulation reference signal is not associated with a port of the second demodulation reference signal. Corresponding to two ports of a data channel DRMS, and a control channel DMRS single port. The DMRS of the data channel is code division multiplexing.

The control channel configures 1 DMRS port, and the data channel configures a plurality of DMRS ports. And at this time, there is a frequency domain OCC (Orthogonal Cover Code ) between DMRS ports of the data channel.

As shown in fig. 5, DMRS port of data channel at this time _1,0 And DMRS port _1,1 And both ports have a frequency domain OCC, e.g. port _1,0 By orthogonal codes [1,1 ]]To demodulate, port _1,1 By [1, -1 ]]To demodulate. At this time, by default, the control channel DMRS port _2,0 And data channelsDMRS port of (a) _1,0 Has an association relationship or is associated by an OCC code used. DMRS of 1 port is configured in the control channel, but the DMRS ports _2,0 Also adopt [1,1 ]]Is demodulated by the frequency domain OCC code of (c). Also, because of DMRS port of data channel _1,0 And port _1,1 The DMRS of the control channel and the DMRS of the data channel occupy the same time-frequency domain resources, and the mapping rule of the DMRS of the control channel and the DMRS of the data channel is the same at this time, so that the association relationship between the DMRS ports of the control channel and the DMRS ports of the data channel can be indicated by the frequency domain OCC codes, that is, the DMRS ports of the associated control channel and the DMRS ports of the data channel have the same OCC codes.

DMRS port in data channel _1,0 And DMRS port in control channel _2,0 Having a QCL relationship, the channel estimation results of the control channel can be used to assist in demodulating DMRS port of the data channel _1,0 . At this time, in order to ensure the demodulation effect of the data channel, the DMRS port of the data channel _1,1 It is desirable to configure the control channel in the frequency domain where the time domain symbol positions of the control channel are used to transmit data traffic (e.g., the lower 4 subcarriers of the 3 rd-5 th time domain symbol in fig. 5), and also to configure the control channel (e.g., the upper 8 subcarriers of the 3 rd-5 th time domain symbol in fig. 5). DMRS port of data channel at this time _1,0 And port _1,1 Has OCC function, occupies the same time-frequency resource, and demodulates reference signal port of data channel _1,0 And control channel demodulation reference signal port _2,0 The physical resource mapping rules of (a) are the same, and at the moment, the DMRS port of the data channel _1,1 Mapping into control channel, the control channel port will appear _2,0 And data channel port _1,1 Occupying the same time-frequency resources as shown in fig. 5.

In order to ensure the accuracy of control channel demodulation, the DMRS port of the data channel is completely removed when the control channel demodulation is performed _1,1 Interference to the control channel. Using OCC characteristics, e.g. DMRS port of control channel at this time _2,0 By using [1,1 ]]Is an OCC code of a data channel DMRS portport _1,1 By using [1, -1 ]]When demodulating, adding the subcarriers demodulated by OCC, and removing the DMRS port of the data channel _1,1 Impact on control channel. Correspondingly, to ensure the DMRS port of the data channel _1,1 When demodulating the data channel, it needs to demodulate the control channel DMRS once, and subtracts the subcarrier demodulated by OCC to remove the port of the control channel DMRS _2,0 Influence on data channel, guarantee data channel DMSR port _1,1 Is effective in demodulation.

To guarantee control channel DMRS port _2,0 And data channel DMRS port _1,1 The orthogonality between demodulation requires a certain modification of the DMRS sequence generation method of the data channel. Wherein this can be solved in two ways:

1) DMRS port of data channel _1,0 Port port _1,1 Using and controlling channel DMRS port _2,0 The same sequence generation mode.

2) The DMRS of the data channel in the frequency domain position (e.g., the lower four subcarriers of the 3 rd-5 th time domain symbol in fig. 5) of the control channel in the time domain symbol position is generated according to the DMRS sequence of the data channel, while the DMRS port of the control channel in the frequency domain position (e.g., the upper eight subcarriers of the 3 rd-5 th time domain symbol in fig. 5) is generated _1,1 And performing sequence generation according to a sequence generation rule of the control channel. I.e. DMRS port _1,1 In fig. 5, the sequence generation method at the 4 th time domain symbol position is different between the frequency domain position (the upper eight subcarriers of the 4 th time domain symbol) of the control channel and the frequency domain position (the lower 4 subcarriers of the 4 th time domain symbol) of the data channel.

Both of the above-described sequence generation methods can be used when the system is configured as an OFDM waveform, and do not affect the use of OCC. But in the single carrier waveform, the DMRS port of the data channel is due to the data channel as shown in fig. 5 _0,1 And port _1,1 Since modulation and demodulation are performed using the OCC, the two ports need to have the same frequency domain RB number when generating the DMRS sequence, so that the characteristics of the OCC can be ensured, at this time, becauseDMRS port of data channel _1,0 And port _1,1 The occupied frequency domain resources are different in position, so that in order to ensure the OCC function between two DMRS ports of a data channel, the two DMRS ports can be modulated and demodulated by utilizing OCC only through the method 2 under the single carrier wave waveform. DMRS port in the frequency domain of control channel _1,1 Is a control channel port _2,0 Is identical, so that the DMRS port of the data channel can be eliminated by the characteristics of the OCC when demodulating the control channel _1,1 In demodulating a data channel, a control channel port can be utilized according to OCC characteristics _2,0 To aid demodulation of data channel DMRS port _1,1 。

According to the control channel DMRS port introduced above _2,0 And DMRS port of data channel _1,0 With QCL association, the control channel DMRS port can be utilized _2,0 Demodulating data channel DMRS port _1,0 And can utilize OCC characteristic to assist in carrying out DMRS port of data channel _1,1 Is performed in the same manner as the demodulation of the signal.

Example six:

referring to fig. 6, m is equal to 6, n is equal to 1, the data channel DMRS is multiport, and the control channel DMRS is single-port.

For the data channels of the DMRS multiport, if there is a control channel of the corresponding port, then the association relationship between the DMRS port of the control channel and each DMRS port of the data channel can be configured, that is, the channel estimation result of the DMRS port of the control channel can be used to assist in demodulating the DMRS port of the data channel.

For the data channels of the multiple DMRS ports, in order to ensure the demodulation characteristic of a single port of the control channel, only 1 port of control channel DMRS is configured at this time. DMRS port for data channels _1,2 、port _1,2 And port _1,4 、port _1,5 DMRS port for control channel _2,0 For frequency division multiplexing, the ports of the data channels are configured to the frequency domain position of the control channel, the sequence of the DMRS and other time domain symbolsThe locations are generated in accordance with the entire allocated bandwidth. For OFDM waveforms, DMRS port of data channel _1,0 And port _1,1 The same sequence may also be configured for OCC multiplexing. For single carrier systems, as in the above embodiments, to guarantee port _1,0 And port _1,1 So that the bandwidth parameter in the sequence generation of DMRS of the data channel at the fourth time domain symbol position is truncated according to the data bandwidth of the current symbol schedule, while the data channel DRMS port in the time domain symbol portion where the control channel is located _1,1 And configuring according to the sequence generation and interception mode of the control channel. The DMRS ports of the data channels on the time domain symbols of the control channel and the data channel frequency division multiplexing may be generated and truncated differently, as in fig. 6, at the fourth time domain symbol position, the DMRS sequence of the data channels, ports _1,0 And port _1,1 Is the same, port _1,2 、port _1,3 And port _1,4 、port _1,5 Is identical but port is the same as the sequence generation and interception of (a) _1,0 、port _1,1 The sequence generation and interception rules are different from those of other ports.

Embodiment seven:

referring to fig. 7, m is equal to 2, n is equal to 2, two ports of the first demodulation reference signal are frequency division multiplexed, two ports of the second demodulation reference signal are frequency division multiplexed, one of the ports of the first demodulation reference signal and one of the ports of the second demodulation reference signal are configured to have an association relationship, and the other port of the first demodulation reference signal and the other port of the second demodulation reference signal have an association relationship.

For the data channels of multiple DMRS ports, the number of ports of DMRS configured by a control channel and a data channel is generally different, and then the channel of each layer of all the data channels cannot be estimated by using the estimation result of the DMRS in the control channel. Taking the data channels of two ports of DMRS as an example, the control channel supports the design of demodulation reference signals of two ports. Control messages by defaultMultiplexing modes among different ports of demodulation reference signals of the channel and the data channel are the same, and meanwhile, the association relation of the ports of the control channel and the data channel is the same as default, namely, the port of the demodulation reference signal of the control channel is associated _2,0 Demodulation reference signal port with data channel _1,0 Associated, demodulation reference signal port of control channel _2,1 Demodulation reference signal port with data channel _1,1 Associated as shown in fig. 7.

In addition to the default information, the association relationship between the control channel demodulation reference signal and the data channel demodulation reference signal may also be indicated by SRI (Sounding reference signal Resource Indicator, sounding reference signal resource indication), TPMI (Transmission Precoding Patrix Indicator, transmission precoding matrix) information. Each demodulation reference signal port in the data channel has the same precoding as the demodulation reference signal port of the associated control channel, so that the association relationship of the demodulation reference signal port of the control channel and the demodulation reference signal port of the data channel can be indicated by the TPMI information.

In addition to the above indication, the first communication node may further indicate an association relationship of the DMRS ports of the control channel and the data channel through signaling, where the signaling includes at least one of: high-layer signaling and dynamic signaling.

Example eight:

referring to fig. 8, m is equal to 2, n is equal to 2, two ports of the first demodulation reference signal are code division multiplexed, two ports of the second demodulation reference signal are also code division multiplexed, one of the ports of the first demodulation reference signal is configured to have an association with one of the ports of the second demodulation reference signal, and the other port of the first demodulation reference signal has an association with the other port of the second demodulation reference signal.

If the DMRS ports of two data channels are OCC, e.g. data channels are configured with DMRS port _1,0 And port _1,1 And these two ports occupy the same time-frequency resource, demodulated by orthogonal code OCC, as shown in fig. 8.

At this time, the two ports of the control channel and the data channel have QCL relations, and the two ports of the control channel support the frequency domain OCC. By default, port of control channel _2,0 DMRS port associated with data channel _1,0 DMRS port of control channel _2,1 DMRS port associated with data channel _1,1 . Or the association relation between the control signal DMRS port and the data signal DMRS port is indicated through the SRI or the TPMI of the respective ports.

Example nine:

referring to fig. 9,M, n is equal to 2, two ports of the first demodulation reference signal are code division multiplexed, frequency division multiplexing is configured between two ports of the second demodulation reference signal, a load of 1 second demodulation reference signal port is configured to transmit information of two ports of the second demodulation reference signal, one port of the first demodulation reference signal has an association relationship with one port of the second demodulation reference signal, and the other port of the first demodulation reference signal has an association relationship with the other port of the second demodulation reference signal.

And configuring the control channel DMRS multiports, wherein the load of the physical resource position is the physical resources of 1 DMRS. Different DMRSs occupy different frequency domain resource transmissions. Taking 4 subcarriers as an example of physical resources corresponding to one DMRS port, two ports of a control channel DMRS are configured, and then the two DMRS ports share the 4 subcarriers resources. Optionally, the first two subcarriers are allocated to one of the two DMRS ports, and the second two subcarriers are allocated to the other port. Optionally, physical resources are flexibly configured according to information to be sent by the port, and the configuration is indicated through high-level signaling or dynamic signaling.

As shown in fig. 9, a control channel DMRS with two ports is designed, and the frequency domain resource position occupied on the same time domain symbol bit is port _2,0 Is a resource location of (a). At this time, the data channel is two DMRS ports, and as can be seen from fig. 9, these two ports are _1,0 、port _1,1 The multiplexing mode of the frequency domain OCC is adopted. Part of the control channel used to transmit the data channel at the time domain symbol positionTwo DMRS ports are also configured. Different DMRS ports in the control channel adopt a frequency division multiplexing mode, and the load of physical resources is 1 port. In the case where there is no transmission of multiple ports of the control channel, only 4 subcarriers are allocated at the position where DMRS is allocated in the control channel, i.e., DMRS port of 1 control channel is shown in fig. 9 _2,0 If the 4 subcarrier positions are configured, the load of the DMRS in the control channel is 4 subcarriers, and the time-frequency domain position of the frequency domain position is configured to be compared with the DMRS port in the data channel by default _1,0 Is allocated to the physical resource of the mobile station.

If there are multiple DMRS ports configured in the control channel. DMRS of multiple ports are transmitted on payload of 1 DMRS. DMRS port in control channel in fig. 9 _2,0 Occupies part of time-frequency domain resources and DMRS port _2,1 The two ports perform 'hop port' transmission according to a certain rule by occupying part of time-frequency domain resource positions, wherein the 'hop port' transmission is to use physical resources of 1 port, and select different ports for transmission at different time-frequency domain resource positions. For example, at DMRS port _2,0 Transmitting DMRS port on load of (a) DMRS port _2,0 And DMRS port _2,1 Information on DMRS port _2,1 Transmitting DMRS port on load of (a) DMRS port _2,0 And DMRS port _2,1 Is a piece of information of (a). Wherein DMRS port of data channel _1,0 Port associated with control channel _2,0 DMRS port of data channel _1,1 DMRS port associated with control channel _2,1 . The information for configuring transmission of two or more DMRS ports with respect to whether there is a payload using 1 DMRS port may be indicated by higher layer signaling.

The above-mentioned code division multiplexing between DMRS ports of the data channel is an example, and if the DMRS ports are frequency division multiplexing, the DMRS ports can be supported without affecting the configuration of the DMRS ports of the control channel.
