Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment is as follows:

in an NR (New Radio, New Radio technology) system, the configuration of demodulation reference signals is flexible, and the configuration of demodulation reference signals may be different in different scenarios. For example, in some scenarios where users are slow, the configuration for the demodulation reference signal in the data channel may occupy a smaller number of time domain symbols in a configuration of one transmission subframe or a non-subframe structure. In some high-speed moving scenarios, more time domain symbols may be needed to transmit demodulation reference signals in the data channel, so as to effectively reduce the problem of inaccurate demodulation caused by high-speed moving, which inevitably leads to an increase in the overhead of the demodulation reference signals.

Accordingly, embodiments of the present invention provide a demodulation reference signal processing method, which improves channel demodulation accuracy while ensuring that overhead of demodulation reference signals is not increased. Referring to fig. 1, the demodulation reference signal processing method mainly includes the following steps:

s101, physical resources to be allocated are obtained, and the physical resources to be allocated comprise first-class channel resources and second-class channel resources.

S102, configuring M first demodulation reference signal ports aiming at first-class channel resources, and configuring N second demodulation reference signal ports aiming at 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 Resource to be allocated includes a Resource Block (RB) and an allocated bandwidth.

Optionally, the first type of channel resources includes time-frequency domain resources where the data channel is located, and the second type of channel resources includes time-frequency domain resources where the control channel is located. The Control Channel includes a PSCCH (Physical Downlink Control Channel), a PUCCH (Physical Uplink Control Channel), a PDCCH (Physical Downlink Control Channel), and the like, and the data Channel includes a PSCCH (Physical Downlink Shared Channel), a PUSCH (Physical Uplink Shared Channel), a PDSCH (Physical 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 used for demodulating the data channel, and the second demodulation reference signal is a demodulation reference signal used 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 is an integer. For example, M is 1,2, 3, … …, and N is 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 and 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 comprises at least one of the following: quasi Co-Located (QCL), identical sequences, identical precoding matrices, and identical Orthogonal Cover Codes (OCC). For example, if the first demodulation reference signal port and the second demodulation reference signal port are configured to have a quasi-common position, it indicates that the first demodulation reference signal port and the second demodulation reference signal port have an association relationship; or the first demodulation reference signal port and the second demodulation reference signal port are configured to have the same sequence, which also can indicate that the first demodulation reference signal port and the second demodulation reference signal port have an association relationship; or configuring the first demodulation reference signal port and the second demodulation reference signal port to have the same precoding matrix, which may also indicate that the first demodulation reference signal port and the second demodulation reference signal port have an association relationship; or the first demodulation reference signal port and the second demodulation reference signal port are configured to have the same OCC code, which may also indicate that the first demodulation reference signal port and the second demodulation reference signal port have an association relationship.

The first demodulation reference signal and the second demodulation reference signal are identical, which may also be represented by that the port sequences associated with the first demodulation reference signal and the second demodulation reference signal are intercepted or generated in the same manner, or the base sequences are identical, or the sequence of the first demodulation reference signal is regarded as a 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 the following: a quasi-co-location relationship between the first demodulation reference signal port and the second demodulation reference signal port, a Sounding reference Signal Resource Indicator (SRI), and a Transmission Precoding Matrix Indicator (TPMI).

Taking the configuration of 2 first demodulation reference signal ports and 2 second demodulation reference signal ports as an example, it is assumed that the 2 first demodulation reference signal ports are respectively ports_1，0、port_1，1The 2 second demodulation reference signal ports are ports respectively_2，0、port_2，1. First demodulation reference signal port_1，0And port of second demodulation reference signal port_2，0An association relationship exists, and the two have a quasi-co-location relationship; further, a first demodulation reference signal port can be configured_1，1And port of second demodulation reference signal port_2，1There is an association relationship, and the two have a quasi-co-location relationship.

Optionally, the first demodulation reference signal port P_1iAnd a second demodulation reference signal port P_2jThere is an association relationship, that is, one of the demodulation reference signals (the first demodulation reference signal port P) configuring the first type of channel resources_1i) And one demodulation reference signal (second demodulation reference signal port P) of the second type channel resources_2j) There is an association relationship.

Optionally, the default configuration i is equal to the default configuration j, that is, the default configuration port identifies two demodulation reference signals (one first demodulation reference signal port and one second demodulation reference signal port) that are the same as (i and j) in association.

Optionally, the multiple ports of the first demodulation reference signal are configured to be frequency division multiplexed or code division multiplexed.

Optionally, the multiple ports of the second demodulation reference signal are configured to be frequency division multiplexed or code division multiplexed.

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: the quasi-co-location relation between the first demodulation reference signal port and the second demodulation reference signal port, high-level signaling and dynamic signaling, wherein the first demodulation reference signal and the second demodulation reference signal use the same transmission precoding matrix identifier. The enabling relationship is whether the two DMRSs are configured on the same time domain symbol or not.

In the NR system, whether a single carrier is used or OFDM (Orthogonal Frequency Division Multiplexing) is used, only the transmission of the information related to the control channel is performed on the time domain symbol bit occupied by the control channel, and no content related to the data service is transmitted. And therefore 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 in the second type of channel resources. The vacant 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 a second type of channel resource. And realizing the alignment of the demodulation reference signals in the second type of frequency domain resources.

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, a sequence generation manner of the first demodulation reference signal port located in the second type of channel resource is the same as a sequence generation 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 sequence of the first demodulation reference signal port located in the first type of channel resources is selected 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, the current position moving rate of the second communication node is obtained, and it is determined that the current moving rate is greater than the preset moving rate. The second communication node is also a communication node serving as a receiving end, and includes, but is not limited to, a vehicle-mounted terminal, a user terminal, a roadside device, 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.

Example two:

in the current NR physical layer structure, the control channel usually occupies only a part of the frequency domain position on the time domain symbol position where the control channel is located, the time-frequency domain resources of the scheduling data service available to V2X are relatively less, frequency division multiplexing is performed by supporting the control channel and the data channel, which is an effective method for improving the frequency domain efficiency of the system.

In the scenario of V2X, sidelink (direct link) communication mainly adopts an uplink physical layer structure, while in the physical layer structure of the current uplink communication system, the time domain symbol position where the control channel is located usually does not occupy the entire allocated bandwidth, and in the current NR technology and the previous Release protocol, there is no good support for transmitting data traffic on the time domain symbol where the control channel is located, and how to demodulate the data traffic. Due to the existence of the control channel, GP (gap), a reference signal and the like, the configurable time frequency resource position of the data service is further compressed. In order to meet different moving speed requirements, flexible demodulation reference signal configuration is supported in the NR system, and the flexible demodulation reference signal configuration can be utilized to meet different moving speed requirements and maximize the spectrum efficiency.

In order to improve the spectrum efficiency of the NR system, the embodiments of the present invention mainly configure the vacant time-frequency resources for data service transmission, for example, the unoccupied frequency-domain resources on the time-domain symbol bit of the control channel are used for data service transmission, and at the same time, because of the data service transmission, how to demodulate? the data at the time-frequency position and how to reduce the overhead? of the demodulation reference signal in the data channel without greatly affecting the 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 the first demodulation reference signal port and the second demodulation reference signal port have an association relationship. 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 parameter configuration of a demodulation reference signal in the data channel through a QCL (Quasi Co-Located) relationship of the control channel and the data channel, wherein the parameter of the demodulation reference signal at least comprises one of the following parameters: the number of ports, the incidence relation with the control channel demodulation reference signal port, the sequence, the frequency domain resource position and the pre-coding mode.

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

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

Example three:

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 is associated with the second demodulation reference signal port. Namely two ports of a data channel DRMS and a single DMRS port 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 with a single-port demodulation reference signal, the data channel is configured with a multi-port demodulation reference signal, and the data channel is configured with two demodulation reference signal ports in fig. 3 as an example. At this time, the control channel is configured with 1 port of demodulation reference signal ports_2,0The data channel is configured with two port ports_1,0And port_1,1. The bandwidth of the time domain symbol position part where the control channel is located is used for sending data service, and in order to ensure the accuracy of data channel demodulation, the control channel is controlled according to the moving speed of the current user (including the receiving end)And configuring a demodulation reference signal for data demodulation on a certain time domain symbol of the time domain symbol position of the control channel, wherein 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 the QCL relationship, so that the data channel can be demodulated by the DMRS in the control channel in an auxiliary mode, and the overhead of a reference signal in the data channel can be reduced under the condition that the demodulation precision of the data channel is guaranteed. But only 1 DMRS port is configured in the control channel_2,0To be able to utilize the DMRS port of the control channel_2,0Demodulate the data channel, so the DMRS port in the control channel is needed_2,0Associated with one DMRS port, in a data channel_1,0Or port_1,1. E.g., control channel port by default_2,0And DMRS port with lowest identification in data channel_1,0Have an association relationship, and both have the same precoding information.

DMRS port of data channel at this time_1,1There is no DMRS port association in the control channel, data channel DMRS port_1,1May be transmitted over a scheduled bandwidth. Avoiding data channel DMRS port_1,1Occupied frequency domain resources, and control channel DMRS port_2,0And (3) the occupied frequency domain resources are collided, and the port of the DMRS (demodulation reference signal) port of the control channel at the moment is predefined_2,0DMRS port with associated data channel_1,0The 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 the occupied frequency domain resource for the two DMRS ports. If the physical resource location multiplexing modes occupied by the two ports are different, the first communication node needs to indicate that the control channel is not configured with the relevant information and signals of the control channel, that is, the unused physical resource location. DMRS port in data channel at this time_1,0And port_1,1For frequency division multiplexing, if the control channel and the data channel are the same time-frequency domain resource allocation rule, at this time, the DMRS port_1,1May occupy the time-frequency domain resourceThe whole allocated bandwidth includes the part of the frequency domain resources on the time domain symbol where the control channel is located. As shown in FIG. 3, a data channel DMRS port_1,1And the time domain symbol bit (4 th time domain symbol) where the DMRS is located in the control channel is also transmitted.

Example four:

referring to fig. 4, the embodiment of the present invention differs from the third embodiment in pattern, and since there is a configurable time-frequency domain pattern for DMRSs, even for different DMRSs, the method described above is also applicable if there are two DMRS ports of a data channel that are frequency division multiplexed. 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 can be configured as a port_1,0And DMRS port_1,2Of DMRS port_1,0And DMRS port of control channel_2,0DMRS port of associated, data channel_1,2And occupying the time-frequency domain resources of part of the control channels.

As shown in fig. 3 and 4, for a single carrier system, the DMRS ports of the two data channels are frequency-divided at this time, and the DMRS ports of the data channels that are not associated with the DMRS ports of the control channel, i.e., the DMRS port ports in fig. 3_1,1And DMRS port in fig. 4_1,2At this time, DMRS sequences for both are generated within the entire allocated bandwidth. Different from the DMRS port in fig. 3_1,1And DMRS port1,2 in fig. 4, DMRS port for data channel_1,0The occupied bandwidth is different from the bandwidths of the two ports, so the sequence of the DMRS port 0 is different from other DMRS ports in the same symbol bit, that is, the DMRS port1 in fig. 1 and the DMRS port 2 in fig. 2.

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

I.e., if there is a QCL relationship between the two, then the demodulation reference signals for demodulating the data channel can be configured on the time domain symbols frequency-division multiplexed by the data channel and the control channel. The first communication node may indicate, through a high-level signaling, for example, through a Radio Resource Control (RRC) signaling or a Media Access Control (MAC CE) signaling, whether to configure a demodulation reference signal of a Control channel and a data channel on the same time domain symbol, or may indicate whether there is frequency division multiplexing of the demodulation reference signals of the data channel and the Control channel in the foregoing manner.

The first communication node indicates the enabling relation of the data channel demodulation reference signal port and the time domain symbol position of the control channel demodulation reference signal port in frequency division multiplexing through the quasi co-location 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, then the demodulation reference signals for demodulating the data channel can be configured on the time domain symbols frequency-division multiplexed by the data channel and the control channel.

The first communication node indicates an enabling relationship of a data channel demodulation reference signal port at a time domain symbol position frequency division multiplexed with a Control channel through signaling, where the signaling may be higher layer signaling or dynamic signaling, where the dynamic signaling includes SCI (Sidelink Control Information) and DCI (Downlink Control Information).

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

Example five:

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 port of the two ports of the first demodulation reference signal and the second demodulation reference signal port are configured to be code division multiplexed, and the second demodulation reference signal port is associated with the other port of the two ports of the first demodulation reference signal. That is, one of the ports of the first demodulation reference signal is not associated with the port of the second demodulation reference signal. The data channel DRMS is equivalent to two ports of a data channel DRMS, and the control channel DMRS is a single port. The DMRS of the data channel is code division multiplexed.

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

As shown in fig. 5, at this time, DMRS port of data channel_1,0And DMRS port_1,1And the two ports have frequency domain OCCs, e.g., port_1,0Using orthogonal codes [1,1 ]]To demodulate, port_1,1With [ 1-1 ]]To demodulate. At this time, under the default condition, the control channel DMRS port_2,0DMRS port for and data channel_1,0Have an association relationship or are associated by the OCC code used. DMRS with 1 port configured in control channel, but the DMRS port_2,0Likewise using [1,1 ]]The frequency domain OCC code of (1) for demodulation. Likewise, because of the DMRS port of the data channel_1,0And port_1,1The same time-frequency domain resources are occupied, and at the moment, the DMRS of the control channel and the DMRS of the data channel have the same mapping rule, so the incidence relation between the DMRS port of the control channel and the DMRS port of the data channel can be indicated by the frequency domain OCC code, namely the associated DMRS port of the control channel and the associated DMRS port of the data channel have the same OCC code.

DMRS port in data channel_1,0And DMRS port in control channel_2,0Have a QCL relationship, and the two are related, then the channel estimation result of the control channel can be used to assist the DMRS port of the demodulation 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_1,1It needs to be configured in the frequency domain where the time domain symbol position of the control channel is used to transmit data service (e.g. the lower 4 subcarriers of the 3 rd to 5 th time domain symbols in fig. 5), and also configured in the control channel (e.g. the upper 8 subcarriers of the 3 rd to 5 th time domain symbols in fig. 5). DMRS port of data channel at this time_1,0And port_1,1Has the functions of an OCC (optical chip carrier) and a chip carrier,both occupy the same time-frequency resource and the port of the demodulation reference signal port of the data channel_1,0And control channel demodulation reference signal port_2,0The mapping rules of the physical resources are the same, and at the moment, the port of the DMRS (demodulation reference signal) port of the data channel_1,1Mapping into a control channel, a control channel port will appear_2,0And data channel port_1,1Occupy the same time-frequency resources as shown in fig. 5.

In order to firstly ensure the accuracy of control channel demodulation, a port of a DMRS (demodulation reference signal) port of a data channel is completely removed when the control channel demodulation is carried out_1,1Interference to the control channel. Using OCC characteristics, e.g. DMRS port of control channel at the time_2,0Using [1,1 ]]OCC code, data channel DMRS port_1,1Using [ 1-1 ]]When in demodulation, the OCC code adds the subcarriers demodulated by the OCC so as to remove a port of a DMRS (demodulation reference signal) port of a data channel_1,1The impact on the control channel. Correspondingly, in order to guarantee the port of DMRS (demodulation reference signal) port of data channel_1,1When demodulating a data channel, the DMRS of the control channel needs to be demodulated once, subcarriers demodulated by using OCC are subtracted, and a port of a DMRS port of the control channel is removed_2,0Influence on data channel, ensuring data channel DMSR port_1,1The demodulation effect of (1).

To guarantee control channel DMRS port_2,0And data channel DMRS port_1,1The orthogonality of demodulation requires some modification to the DMRS sequence generation manner of the data channel. This can be solved in two ways:

1) DMRS port for data channel_1,0Port, port_1,1DMRS port with control channel_2,0The same sequence generation.

2) The DMRS of the data channel frequency domain location (e.g., the lower four subcarriers of the 3 rd-5 th time domain symbol in FIG. 5) at the time domain symbol location of the control channel is generated according to the DMRS sequence of the data channel, and the DMRS port of the frequency domain location (e.g., the upper eight subcarriers of the 3 rd-5 th time domain symbol in FIG. 5) at the control channel is generated according to the DMRS sequence of the data channel_1,1According to the sequence of the control channelAnd generating a sequence in a regular way. I.e. DMRS port_1,1In fig. 5, the sequence generation manner at the 4 th time domain symbol position is different between the frequency domain position of the control channel (the upper eight subcarriers of the 4 th time domain symbol) and the frequency domain position of the data channel (the lower 4 subcarriers of the 4 th time domain symbol).

The two sequence generation modes can be used when the system is configured to be an OFDM waveform, and the use of OCC is not influenced. But under single carrier waveform, since as shown in fig. 5, the data channel DMRS port_0,1And port_1,1The modulation and demodulation are carried out by using the OCC, so that the two ports need to have the same frequency domain RB number when generating the DMRS sequences, and the characteristic of the OCC can be ensured at the moment, because the DMRS port of the data channel_1,0And port_1,1The occupied frequency domain resource positions are different in size, and in order to ensure the OCC function between the two DMRS ports of the data channel, under the single carrier waveform, the two DMRS ports can be ensured to be modulated and demodulated by using the OCC only by the method 2. DMRS port in frequency domain of control channel_1,1Sequence of (2) and control channel port_2,0Are identical, so when demodulating the control channel, the data channel DMRS port can be eliminated by the characteristics of the OCC_1,1Can utilize the control channel port according to the OCC characteristics when demodulating the data channel_2,0To assist demodulation of DMRS port of data channel_1,1。

DMRS port according to the control channel introduced above_2,0DMRS port for and data channel_1,0Having QCL association, DMRS port can be utilized for control channel_2,0To demodulate a data channel DMRS port_1,0And data channel DMRS port can be assisted by using OCC characteristics_1,1And (4) demodulating.

Example six:

referring to fig. 6, M is equal to 6, N is equal to 1, a data channel DMRS is multi-ported, and a control channel DMRS is single-ported.

For a data channel with multiple ports for DMRS, if a control channel of a corresponding port exists, the association relationship between the DMRS port for the control channel and each DMRS port for the data channel can be configured, that is, the channel estimation result of the DMRS port for the control channel can be used for assisting in demodulating the DMRS port for the data channel.

For a data channel with multiple DMRS ports, only the DMRS of 1 port is configured at the time in order to ensure the demodulation characteristic of a single port of a control channel. DMRS port for data channel_1,2、port_1,2And port_1,4、port_1,5DMRS port with control channel_2,0For frequency division multiplexing, the ports of the data channels are configured to the frequency domain position of the control channel, and the sequences of the DMRS and other time domain symbol positions are generated according to the whole allocated bandwidth. For OFDM waveforms, DMRS port of data channel_1,0And port_1,1It can also be configured with the same sequence for OCC multiplexing. For single carrier systems, as shown in the above embodiments, to guarantee port_1,0And port_1,1The bandwidth parameter in the DMRS sequence generation for the data channel at the fourth time-domain symbol position is truncated according to the data bandwidth scheduled by the current symbol, and the DRMS port for the data channel in the time-domain symbol portion where the control channel is located_1,1The sequence generation and interception of (2) is configured according to the sequence generation and interception mode of the control channel. Therefore, the DMRS port of the data channel may be generated and intercepted in different ways on the time domain symbols of the frequency division multiplexing of the control channel and the data channel, e.g., in fig. 6, at the fourth time domain symbol position, the DMRS sequence of the data channel, and the port_1,0And port_1,1Are identical, port_1,2、port_1,3And port_1,4、port_1,5Is identical, but port_1,0、port_1,1The sequence generation and interception rules are different from those of other ports.

Example 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, and one port of the first demodulation reference signal and one port 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 a data channel with multiple DMRS ports, normally, the number of DMRS ports configured for a control channel and the data channel is different, and at this time, the channel of each layer of all the data channels cannot be estimated using the estimation result of the DMRS in the control channel. Taking the data channel of two ports of DMRS as an example, the control channel supports the design of demodulation reference signals of two ports at this time. The multiplexing modes of different ports of demodulation reference signals of the control channel and the data channel are the same under default conditions, and the association relationship of the ports of the control channel and the data channel is the same as default, namely the port numbers of the demodulation reference signals of the control channel are associated, namely the port of the demodulation reference signal port of the control channel_2,0Demodulation reference signal port with data channel_1,0Associated, demodulation reference signal port of control channel_2,1Demodulation reference signal port with data channel_1,1Correlated as shown in fig. 7.

Besides 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) and TPMI (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 the association relationship between 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 DMRS ports of a control channel and a data channel through signaling, wherein the signaling includes at least one of: high layer signaling, 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, and it is configured that one port of the first demodulation reference signal is associated with one port of the second demodulation reference signal, and the other port of the first demodulation reference signal is associated with the other port of the second demodulation reference signal.

If the DMRS ports of two data channels are OCC, e.g., the data channels are configured with DMRS port_1,0And port_1,1And the two ports occupy the same time-frequency resource and are 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 relationship, respectively, and the two ports of the control channel support the frequency domain OCC. By default, control channel port_2,0DMRS port associated with data channel_1,0DMRS port for control channel_2,1DMRS port associated with data channel_1,1. Or indicating the association relation of the control signal DMRS port and the data signal DMRS port through the SRI or TPMI of the respective ports.

Example nine:

referring to fig. 9, M is equal to 2, 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, 1 load of the second demodulation reference signal ports is configured to send information of two ports of the second demodulation reference signal, one port of the first demodulation reference signal is associated with one port of the second demodulation reference signal, and the other port of the first demodulation reference signal is associated with the other port of the second demodulation reference signal.

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

As shown in fig. 9, two-port DMRSs are designed, and the occupied frequency domain resource location on the same time domain symbol bit is a port_2,0The resource location of (2). The data channel is now two DMRS ports, and as can be seen in fig. 9, these two port ports_1,0、port_1,1And a multiplexing mode of frequency domain OCC is adopted. Two DMRS ports are also configured at the part of the time domain symbol position where the control channel is located for transmitting the data channel. Different DMRS ports in the control channel adopt a frequency division multiplexing mode, and the load of physical resources is the load of 1 port. In the case that there is no control channel with multiple port transmission, only 4 subcarriers are configured at the position where DMRS is configured in the control channel, i.e., DMRS port of 1 control channel as shown in fig. 9_2,0If 4 subcarrier positions are originally 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 match the port of the DMRS port in the data channel under the default condition_1,0The physical resource configuration of (1).

If there is a configuration of multiple DMRS ports in the control channel. DMRSs for multiple ports are transmitted on payload of 1 DMRS. DMRS port in control channel in FIG. 9_2,0Occupies partial time-frequency domain resources, DMRS port_2,1The method is characterized in that the positions of partial time-frequency domain resources are occupied, two ports carry out 'hop port' sending according to a certain rule, the 'hop port' sending is that physical resources of 1 port are used, and different ports are selected to carry out sending at different time-frequency domain resource positions. E.g. at DMRS port_2,0On-load sending of DMRS port_2,0And DMRS port_2,1Information of (3), port at DMRS port_2,1On-load sending of DMRS port_2,0And DMRS port_2,1The information of (1). Wherein the dataDMRS port for a channel_1,0Port port associated with control channel_2,0DMRS port for data channel_1,1DMRS port associated with control channel_2,1. Information configuring the transmission of two or more DMRS ports for whether there is payload with 1 DMRS port may be indicated by higher layer signaling.

The above-mentioned code division multiplexing among the 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.
