Detailed Description

Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless it is specifically stated otherwise.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and apparatus should be considered part of the specification.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

DMRS of NR (New Radio) protocol are of two types, type) 1 and Type2. Since the number of REs occupied by each port is different on average for Type1 and Type2, there are different applicable scenarios. Type1 is more suitable for scenes with low signal-to-noise ratio and higher frequency domain selectivity, while Type2 is more suitable for scenes with high signal-to-noise ratio and smaller delay spread.

For DMRS of single symbol, DMRS Type1 supports at most 4 orthogonal ports, and DMRS Type2 supports at most 6 orthogonal ports; for dual symbol DMRS, DMRS Type1 supports up to 8 orthogonal ports and DMRS Type2 supports up to 12 orthogonal ports.

As described above, since the above protocol defines only a maximum of 12 orthogonal demodulation reference signal DMRS ports, the user pairing capability and the total data transmission stream number are limited, thereby affecting the network transmission capability and the service performance. Especially in a Multi-TRP (multiple transmission point) joint transmission scenario, the probability of simultaneously transmitting 12 streams of data and above is greatly increased, and increasing the number of DMRS ports is an effective method.

For increasing the number of DMRS ports, two ways can be distinguished: increasing the number of non-orthogonal ports of the DMRS and increasing the number of orthogonal ports of the DMRS.

The data of more than 12 flows are processed by increasing the number of the non-orthogonal ports of the DMRS, and the transmission of the non-orthogonal ports can introduce larger interference due to stronger correlation of the DMRS sequences defined by the protocol, so that the accuracy of channel estimation is reduced. This technical problem is particularly pronounced in Multi-TRP scenarios.

The number of orthogonal ports of the DMRS can be increased by increasing the time-frequency resources occupied by the DMRS. However, this approach can significantly increase pilot overhead.

Therefore, there is a need to increase the number of DMRS orthogonal ports without adding additional DMRS symbols, and to be compatible with DMRS configurations specified by existing protocols.

Aiming at the technical problems, the present disclosure proposes a technical scheme for configuring DMRS to increase the number of DMRS orthogonal ports. That is, the present disclosure can increase the number of DMRS orthogonal ports to promote the number of data transmission streams without increasing pilot overhead and DMRS configuration compatible with existing protocols. Therefore, the network transmission rate is improved to meet the new service requirements of Rel-18 and 5G Advanced.

In some embodiments, the multiport DMRS primarily involves data channels including PUSCH and PDSCH. Since the two are similar, the following is exemplified by PDSCH DMRS, and the technical scheme is also applicable to PUSCH.

Resources in the same code division multiplexing CDM group cannot be distinguished from each other by frequency domains and time domains, and can only be distinguished by code domains, namely, OCC codes are adopted to realize distinguishing. Can be divided into frequency domain code division and time domain code division, and respectively corresponds to w _f (k') and w _t (l') parameters.

The DMRS configuration specified by the current protocol fixedly adopts an OCC code length of 2, and does not support superposition of other OCC code sequences.

For OCC code length of 2, the corresponding OCC sequence is [1,1], [1, -1]. Within the same CDM group, orthogonal transmission of 2 DMRS ports can be achieved by superposition of OCC sequences with a code length of 2. Similarly, within the same CDM group, orthogonal transmission of N DMRS ports can be achieved by superposition of OCC sequences with a code length of N.

DMRS configuration according to current protocol specification: in the time domain, the pre-DMRS configuration supporting single symbol and double symbol has at most two RE resources. Therefore, the code length of the time domain OCC is 2 at maximum, and the number of the DMRS orthogonal ports cannot be increased by increasing the code length of the time domain OCC; in the frequency domain, for the pre-Type 1 DMRS, there are two CDM groups, one CDM group has 6 RE resources, and theoretically, the frequency domain OCC code length is 6 at most, that is, 6 orthogonal DMRS ports are supported at most; for the pre-Type 2 DMRS, there are 3 CDM groups, each with 4 RE resources, and theoretically the frequency domain OCC code length is 4 at maximum, i.e. 4 orthogonal DMRS ports are supported at most.

Therefore, the number of DMRS orthogonal ports can be increased by increasing the frequency domain OCC code length. For example, the technical solution of the present disclosure may be implemented by the following embodiments.

Fig. 1 illustrates a flow chart of some embodiments of a method of configuring resources of the present disclosure.

As shown in fig. 1, in step 110, the length of the DMRS frequency domain OCC is configured according to a preset field in a preset signaling. For example, according to the preset field, the length of the OCC is increased, and the length of the increased OCC is greater than 2.

In some embodiments, the preset signaling includes at least one of RRC signaling, MAC CE, DCI, and the preset field is determined according to the length of the increased OCC indicated by the preset parameter. For example, the preset parameter may be a high-level parameter; the RRC signaling may include at least one of DMRS-Downlink Config or DMRS-Uplink Config.

Thus, the length of the OCC is flexibly configured through signaling, and further the orthogonal DMRS ports are flexibly configured. Therefore, the method can adapt to different transmission requirements and improve the communication performance.

For example, a field may be added to at least one of DMRS-downlink config or DMRS-uplink config of RRC signaling for identifying the length of OCC of DMRS in the frequency domain.

For example, the added field may be frequencyDomainOCC INTEGER (0 …-1) or frequencyDomainOCC INTEGER (0 … ->-1)。/>Andthe maximum values of the lengths of DMRS frequency domain OCCs of PDSCH and PUSCH are indicated by the higher layer parameters, respectively.

In some embodiments, the length of OCC of DMRS frequency domain of at least one of PDSCH or PUSCH is configured.

In step 120, a corresponding number of orthogonal DMRS ports are configured according to the length of the OCC.

In some embodiments, configuring a corresponding number of orthogonal DMRS ports according to the length of the OCC comprises: and determining the number of the orthogonal DMRS ports which can be supported by each CDM group according to the length of the increased OCC, wherein the number of the orthogonal DMRS ports which can be supported by each CDM group is equal to the length of the increased OCC.

For example, generating a number of OCC sequences corresponding to the length of the increased OCC; orthogonal DMRS ports supported by each CDM group are configured according to the OCC sequence.

In some embodiments, DMRS configuration related parameters in the protocol are modified. For example, the relevant parameters mainly relate to resource mapping of DMRS in the frequency domain direction. In PDSCH DMRS examples: for each CDM group, how large the OCC length in the frequency domain is, how many orthogonal DMRS ports can be supported.

For example, the OCC sequence may be generated by the following formula:

m＝0,1,...N _OCC -1

N _OCC the length of OCC is represented by a positive integer such as {1,2,3,4,5,6,7, … }. For example, N _OCC The value of (2) can be indicated by high-level parameters such as 2, 4, 6, etc.; p represents a DMRS port index in the frequency domain within a CDM group, which may range from 0,1, … N _OCC -1; m is the sequence number of OCC in the OCC sequence; w (w) _f ^p (m) is the mth OCC in the OCC sequence;generating a function.

In some embodiments of the present invention, in some embodiments,the values of (2) are shown in Table 1:

TABLE 1

For example, according to the above formula and the data in Table 1, when N _OCC When=2, i.e., the length of OCC is 2, it can be calculated that the corresponding OCC sequence includes 2 OCCs of [ +1, respectively]、[+1,-1]。

For example, according to the above formula and the data in Table 1, when N _OCC When=4, i.e., the length of OCC is 4, it can be calculated that the corresponding OCC sequence includes 4 OCCs of [ +1, respectively]、[+1,-1,+1,-1]、[+1,+1,-1,-1]、[+1,-1,-1,+1]。

In the case where the length of OCC is other value, the OCC sequence including the corresponding number of OCCs can be calculated by the above formula.

In step 130, mapping of DMRS physical resources is completed according to the configured orthogonal DMRS ports.

In some embodiments, according to the orthogonal DMRS ports, a time-frequency domain position of each DMRS RE is determined, and mapping of physical resources is performed. For example, the time-frequency domain position of each DMRS RE may be determined according to the DMRS configuration, so as to complete the physical resource mapping.

In some embodiments, the length N of the OCC is in the frequency domain _OCC For Type1, the DMRS of single symbol supports at most 8 orthogonal DMRS ports, and the DMRS of double symbol supports at most 16 orthogonal DMRS ports, =4 for example; for Type2, a single-symbol DMRS supports a maximum of 12 orthogonal DMRS ports, and a dual-symbol DMRS supports a maximum of 24 orthogonal DMRS ports. Compared with the current protocol, the number of the orthogonal ports of the DMRS is doubled, and the communication performance is improved.

For example, the orthogonal DMRS ports for Type1 and their corresponding OCCs are shown in table 2:

TABLE 2

Lambda is the offset in the expression of the mapping relationship of the DMRS on the physical resource.

For example, the orthogonal DMRS ports for Type2 and their corresponding OCCs are shown in table 3:

TABLE 3 Table 3

In some embodiments, a respective number of orthogonal DMRS ports configured according to the length of the OCC are allocated to each CDM group; in the time domain, each CDM group shares 1 symbol in the time domain; in the frequency domain, subcarriers are divided into a plurality of subcarrier groups, each subcarrier group including at least 1 subcarrier, each subcarrier group is assigned to each CDM group, and adjacent subcarrier groups are assigned to different CDM groups.

In some embodiments, subcarrier groups are alternately allocated to CDM groups in order in the frequency domain. The above technical solution can be achieved, for example, by the following embodiments.

Fig. 2 a-2 d illustrate schematic diagrams of some embodiments of a method of configuring resources of the present disclosure.

As shown in FIGS. 2 a-2 d, the OCC code length N is used in the frequency domain _OCC For example, =4, i.e. at least one of the RRC signaling DMRS-downlink config or DMRS-uplink config identifies that the OCC code length of the DMRS in the frequency domain is 4. For single symbol DMRS, 4 DMRS orthogonal ports are supported per CDM group; for a dual symbol DMRS, 8 DMRS orthogonal ports are supported per CDM group. The DMRS resource mapping is the same as that specified by the current protocol, except that the number of orthogonal ports supported by each CDM group is doubled.

As shown in fig. 2a to 2d, k represents an index of a resource in a frequency domain, and l represents an index of a symbol in a time domain; one PRB (Physical Resource Block ) is shown with 14 symbols in the time domain and 12 subcarriers in the frequency domain.

As shown in FIGS. 3 a-3 d, the length N of the OCC is in the frequency domain _OCC For DMRS Type1, type1 is more suitable for a scene with low signal-to-noise ratio and high frequency domain selectivity, for example, =4. Compared with the Type1 DMRS mapping method in the embodiments of fig. 2a to 2d, the difference is mainly that the degree of dispersion in the frequency domain is different, i.e. the frequency domain selectivity is different. For example, the frequency domain resources may be deployed according to network reality.

Compared with the Type1 DMRS mapping method in the embodiments of fig. 2a to 2d, the difference is mainly that the degree of dispersion in the frequency domain is different, i.e. the frequency domain selectivity is different. For example, the frequency domain resources may be deployed according to network reality.
