The embodiment of the invention provides an information configuration method, an information configuration device, network equipment and terminal equipment, which solve the problem that the current DMRS configuration mode has larger influence on channel estimation performance when SCS is larger.

The method, the corresponding device, the corresponding network device or the terminal device are based on the same application conception, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be mutually referred to, and the repetition is not repeated.

As shown in fig. 3, an embodiment of the present invention provides an information configuration method, including:

step 31: the network device transmits DCI including first indication information to the terminal device.

The first indication information is used for indicating the FD-OCC switch state of the DMRS.

Optionally, the FD-OCC switch states include: the FD-OCC switch is turned on and the FD-OCC switch is turned off.

In this embodiment, the network device sends DCI including first indication information for indicating an FD-OCC switching state of the DMRS to the network device, so as to implement a function of system support FD-OCC switching off, so that the terminal device may switch off the FD-OCC when SCS is higher according to the DC, the terminal device may determine that no other terminal device multiplexes resources, and may independently estimate a channel for each Resource Element (RE), and may increase the density of the DMRS when detecting, thereby improving channel estimation performance under SCS. And when the number of users in the system is large, the FD-OCC can be flexibly started through the scheme so as to start multi-user frequency domain resource multiplexing and avoid the limitation of the system capacity.

Optionally, before the network device sends the DCI including the first indication information to the terminal device, the method further includes:

Alternatively, the terminal device (UE) may report to the network device whether it has the capability to dynamically switch FD-OCC. If the UE supports dynamic switching FD-OCC, the network device may turn on the function of the dynamic switching FD-OCC, as indicated by the new port allocation table (e.g., table 3-1, table 3-2, table 4-1, table 4-2, etc.). If the UE does not support dynamic switching FD-OCC or the network device side does not turn on the function although the UE supports the capability of dynamic start FD-OCC, the indication is according to the original port allocation table (e.g. table 1-1, table 1-2, table 2-1, table 2-2, etc. as described above).

For example: the network device may determine whether the DMRS RE is required to turn on the FD-OCC according to SCS configuration of the current system and user traffic conditions in the system. And determining DCI comprising the first indication information according to the determined result of whether the DMRS RE is required to turn on the FD-OCC so as to indicate the FD-OCC on-off state of the DMRS through the first indication information.

For example: the network device configures whether PDSCH DMRS RE of the user turns on the FD-OCC through the Antenna port field of DCI format1-1 or 1-2.

For example: the network device configures whether the PUSCH DMRS RE of the user starts the FD-OCC or not through the Antenna port field of DCI formats 0-1 or 0-2.

For example: the network device may configure the FD-OCC switch state configuration table for the terminal device in advance, so that the network device may implement the FD-OCC switch state for indicating the DMRS by carrying the related information of the index in the DCI (for example, the indication index may be displayed or the implicit indication index may be displayed). Or the FD-OCC switch state configuration table may be predetermined by a protocol, so that the network device may implement the FD-OCC switch state indicating the DMRS by carrying the related information of the index in the DCI (e.g., may display the indication index or the implicit indication index).

FD-OCC switch state configuration table of DMRS of the dual-symbol first type;

FD-OCC switch state configuration table of DMRS of single symbol second type;

FD-OCC switch state configuration table for DMRS of the two-symbol second type.

The first Type of DMRS is Type1-DMRS; the second Type of DMRS is Type2-DMRS.

For example: for single symbol Type1-DMRS, index, DMRS CDM group number without data, DMRS port, FD-OCC switch state (FD-OCC ON) configuration may be indicated by 4 bits as shown in table 3-1.

Table 3-1: antenna port (1000+dmrs port), dmrs-type=1, longest length=1;

For the dual symbol Type1-DMRS, the index, DMRS CDM group number without data, DMRS port, preamble symbol number, FD-OCC switch state configuration may be indicated by 6 bits as shown in table 3-2.

Table 3-2: antenna port (1000+dmrs port), dmrs-type=1, longest length=2;

For single symbol Type2-DMRS, index, DMRS CDM group number without data, DMRS port, FD-OCC switch state configuration may be indicated by 5 bits as shown in table 4-1.

Table 4-1: antenna port (1000+dmrs port), dmrs-type=2, longest length=1;

For the dual symbol Type2-DMRS, the index, the DMRS CDM group number without data, the DMRS port, the number of preamble symbols, and the FD-OCC switch state configuration may be indicated by 6 bits as shown in table 4-2.

Table 4-2: antenna port (1000+dmrs port), dmrs-type=2, longest length=2;

Specifically, taking the above table 4-2 as an example, the index 0 corresponding to one codeword may represent DMRS CDM group number 1 without data corresponding to DMRS port 0, the number of front load symbols is 1, and the fd-OCC switch state is on; an index 58 corresponding to one codeword indicates that DMRS CDM group number 1 without data corresponds to DMRS port 0, the number of front carriers is 1, and the fd-OCC switch state is off. Other configuration tables may also be used in a similar manner as described above, and will not be described in detail herein.
