Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The correspondence between DMRS (Demodulation Reference Signal, demodulation reference signal) CDM group (CodeDivision Multiplexing Group, code division multiplexing group) and DMRS port is as follows:

DM-RS configuration (configuration) type (type) 1.

DMRS configuration type 2.

The DMRS base sequence of the UE in the existing first communication mode is:

The DMRS base sequence of the UE in the existing second communication mode is:

where

n' _SCID (λ=0)=n _SCID

n' _SCID (λ=1)=1-n _SCID

n' _SCID (λ=2)=n _SCID

Among them, nSCID is a parameter indicated by DCI (Downlink Control Information, downlink control information), the value is 0 or 1; λ represents CDM Group, and the value is 0, 1, 2.

By comparison, it can be found that

When λ=0, the base sequence of the second communication mode is the same as the base sequence of the first communication mode;

When λ=1, the base sequence of the second communication mode and the base sequence of the first communication mode are only different in nSCID;

When λ=2, the base sequence of the second communication mode is 217 more than the base sequence of the first communication mode.

The difference in the base sequence of the first communication mode and the second communication mode brings the following problems:

When using MU-MIMO (Multi-User Multiple-Input Multiple-Output) in the first communication mode and the second communication mode, if Configuration Type 1 is used:

As shown in Table 1: if the port (port) of the UE (User Equipment) in the second communication mode and the UE in the first communication mode comes from CDM group 0, for example, port 0 is used in the first communication mode, and port 0 is used in the second communication mode. If port1 is used, the base sequence of the UE in the second communication mode is the same as that of the UE in the first communication mode, and there is no problem with MU-MIMO demodulation;

If the port between the UE in the second communication mode and the UE in the first communication mode comes from CDM group 1, for example, port 2 is used in the first communication mode and port 3 is used in the second communication mode, then the UE in the second communication mode and the first communication mode The UE base sequences of different UEs are different, and each other does not know each other's sequence during MU-MIMO, and cannot demodulate;

When using MU-MIMO in the first communication mode and the second communication mode, if Configuration Type 2 is used:

If the port between the UE in the second communication mode and the UE in the first communication mode comes from CDM group 0, for example, port 0 is used in the first communication mode and port 1 is used in the second communication mode, then the UE in the second communication mode and the first communication mode UE base sequence is the same, MU-MIMO demodulation is no problem;

If the port between the UE in the second communication mode and the UE in the first communication mode comes from CDM group 1, for example, port 2 is used in the first communication mode and port 3 is used in the second communication mode, then the UE in the second communication mode and the first communication mode The UE base sequences of different UEs are different, and each other does not know each other's sequence during MU-MIMO, and cannot demodulate;

As shown in Table 2: if the port between the UE in the second communication mode and the UE in the first communication mode is from CDM group2, for example, port 4 is used in the first communication mode and port 5 is used in the second communication mode, the UE in the second communication mode Different from the UE base sequence in the first communication mode, in MU-MIMO, each other does not know the sequence of the other party and cannot demodulate.

Table 1

Table 2

The base sequences of the first communication mode and the second communication mode are different, so when the first communication mode and the second communication mode do MU-MIMO, they cannot complete the correct demodulation because they do not know each other’s base sequence, which brings the first communication mode and the compatibility issue of the second communication mode UE. This problem is mainly caused by the change of the DMRS base sequence by the UE in the second communication mode.

In order to solve the above problems, the embodiments of the present invention provide a reference signal configuration method and device, and communication equipment, which can allow a terminal in the first communication mode to communicate between the DMRS base sequence of the first communication mode and the DMRS base sequence of the second communication mode Switch flexibly.

The technical scheme of the present invention is further introduced below:

When there are many UEs in the first communication mode in the network (that is, terminals that comply with the first communication mode protocol), the network can directly configure UEs in the second communication mode in the cell (that is, terminals that follow the second communication mode protocol) to use the first communication mode. The DMRS base sequence of the communication mode is convenient to do MU (Multi-User, multi-user) pairing with the UE of the first communication mode;

When there are many UEs in the second communication mode in the network, most of the UEs in the second communication mode can be configured to use the DMRS base sequence of the second communication mode, and only a small number of UEs in the second communication mode can use the first communication mode. mode DMRS base sequence, and let these UEs perform MU pairing with UEs in the first communication mode.

However, the number of UEs in the first communication mode and the second communication mode in the network is almost the same. At this time, the UE configured by the network in the second communication mode can use both the DMRS base sequence of the first communication mode and the DMRS base sequence of the second communication mode. sequence, and through DCI (Downlink Control Information, downlink control information), the UE in the second communication mode can flexibly switch between the first communication mode and the second communication mode DMRS base sequence.

In the technical solution of this embodiment, according to the proportion of UE types in the network, through RRC (Radio Resource Control, radio resource control) + DCI indication, the UE in the second communication mode can flexibly operate between the first communication mode and the second communication mode. Switch between two communication modes DMRS base sequences.

First, the network side can configure the DMRS base sequence through the RRC message to be selected from {the first communication mode DMRS base sequence, the second communication mode DMRS base sequence, the first communication mode or the second communication mode DMRS base sequence};

When the proportion of UEs in the second communication mode in the network is less than 20%, the RRC message configures the UEs in the second communication mode to use the DMRS base sequence of the first communication mode, without DCI activation, and the UE can directly select the base sequence according to the RRC configuration;

When the proportion of UEs in the second communication mode in the network is greater than 80%, RRC configures that most of the UEs in the second communication mode use the DMRS base sequence of the second communication mode, and a small part of the UEs in the second communication mode use the DMRS in the first communication mode. The base sequence does not require DCI activation, and the UE can directly select the base sequence according to the RRC configuration;

When the proportion of UEs in the second communication mode in the network is between 20% and 80%, RRC configures the UEs in the second communication mode to use the DMRS base sequence of the first communication mode or the second communication mode, and the UE needs to combine DCI activation to determine itself base sequence:

When the UE in the second communication mode and the first communication mode do In MU-MIMO, the DCI indicates 0, so that the CDM group 1 of the UE in the second communication mode adopts the DMRS base sequence of the first communication mode, as shown in Table 3:

table 3

DCI DMRS base sequence 0 The first communication mode DMRS base sequence 1 Second communication mode DMRS base sequence

For DMRS Configuration Type 2:

CDM group 0: The DMRS base sequence of the second communication mode is the same as the DMRS base sequence of the first communication mode, and no switching is required;

CDM group 1 and CDM group 2: 1bit DCI is required to indicate whether CDM group 1 and CDM group 2 adopt the DMRS base sequence of the first communication mode or the DMRS base sequence of the second communication mode, as shown in Table 4:

Table 4

Or CDM group 1 and CDM group 2: 2bit DCI is required to jointly indicate whether CDM group 1 and CDM group 2 adopt the DMRS base sequence of the first communication mode or the DMRS base sequence of the second communication mode, as shown in Table 5:

table 5
