[0014] In order to solve the problems of the prior art, the embodiments of the present invention provide a method for configuring channel quality indication information, a corresponding device and a storage medium. The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0015] In the following description, prefixes such as “first”, “second”, etc. used to distinguish elements are only used to facilitate the description of the embodiments of the present invention, and have no specific meaning by themselves.

[0016] Embodiment 1

[0017] like Figure 1 As shown, an embodiment of the present invention provides a method for configuring channel quality indication information, the method comprising:

[0018] S101, selecting P CQI tables from pre-configured channel quality indicator CQI tables according to the terminal type of the terminal; wherein P is an integer of 2 or greater than 2;

[0019] S102: Indicate a CQI table from the selected P CQI tables to the terminal.

[0020] The embodiment of the present invention is executed in a transmitting end, wherein the transmitting end includes equipment such as a base station, a terminal, a relay, and a transmitting point.

[0021] In an embodiment of the present invention, P CQI tables are selected from a pre-configured channel quality indication CQI table according to the terminal type of the terminal, and a CQI table is indicated to the terminal from the P CQI tables. Such processing can effectively save signaling overhead, indicate CQI table configuration information for different types of terminals, and can cover all CQI modulation modes and coding efficiencies, thereby ensuring the stability of data transmission.

[0022] Based on the above embodiment, modifications of the above embodiment are proposed.

[0023] The following takes P being 2 as an example to illustrate various variant embodiments.

[0024] In the embodiment of the present invention, optionally, indicating one CQI table from two CQI tables to the terminal specifically includes:

[0025] A high-layer configuration signaling is sent to the terminal, where the high-layer configuration signaling is used to indicate a CQI table to the terminal.

[0026] Wherein, before selecting two CQI tables from a pre-configured channel quality indicator CQI table according to the terminal type of the terminal, the method further comprises:

[0027] According to the terminal type, a maximum modulation mode supported by the terminal is determined.

[0028] For example, according to the modulation mode, the terminal types include 64QAM (Quadrature Amplitude Modulation) terminal type, 256QAM terminal type, and 1024QAM terminal type, etc. Among them, the maximum modulation mode corresponding to the 64QAM terminal type is 64QAM, the maximum modulation mode corresponding to the 256QAM terminal type is 256QAM, and the maximum modulation mode corresponding to the 1024QAM terminal type is 1024QAM.

[0029] In the embodiment of the present invention, optionally, the selected two CQI tables include at least a first CQI table, and the maximum modulation mode of the first CQI table is 64QAM.

[0030] In the embodiment of the present invention, optionally, the selected two CQI tables include at least a second CQI table, and the maximum modulation mode of the second CQI table is the maximum modulation mode corresponding to the terminal type or the maximum modulation mode supported by the transmitter.

[0031] Among them, the smaller modulation mode of the maximum modulation mode corresponding to the terminal type and the maximum modulation mode supported by the transmitting end is the maximum modulation mode of the second CQI table.

[0032] Specifically, when the maximum modulation mode supported by the transmitting end is greater than or equal to the maximum modulation mode corresponding to the terminal type, the maximum modulation mode supported between the transmitting end and the terminal is the maximum modulation mode supported by the terminal. At this time, the maximum modulation mode of the second CQI table is the maximum modulation mode corresponding to the terminal type;

[0033] When the maximum modulation mode supported by the transmitting end is less than the maximum modulation mode corresponding to the terminal type, the maximum modulation mode supported between the transmitting end and the terminal is the maximum modulation mode supported by the transmitting end. At this time, the maximum modulation mode of the second CQI table is the maximum modulation mode supported by the transmitting end.

[0034] The embodiment of the present invention selects 2 CQI tables from all pre-configured CQI tables. Although the number of available CQI tables is reduced, the 2 CQI tables include at least a CQI table (first CQI table) with a maximum modulation mode of 64QAM and a CQI table (second CQI table) with a maximum modulation mode of the maximum modulation mode supported by the terminal, thereby covering all CQI modulation modes and coding efficiencies and ensuring the stability of data transmission.

[0035] In the embodiment of the present invention, optionally, the number of the pre-configured channel quality indication CQI tables is an integer not less than 3, and the high-level configuration signaling is 1-bit information.

[0036] That is to say, optionally, when the transmitting end is configured with 3 or more CQI tables, 2 CQI tables are selected, and a 1-bit high-layer configuration signaling is used to instruct the terminal to use one of the 2 CQI tables.

[0037] In the embodiment of the present invention, optionally, the high-level configuration signaling is used to indicate a CQI table to the terminal, including:

[0038] When the maximum modulation mode corresponding to the terminal type is 1024QAM, the high-layer configuration signaling indicates a CQI table with a maximum modulation mode of 64QAM or a CQI table with a maximum modulation mode of 1024QAM to the terminal.

[0039] That is, in an embodiment of the present invention, when the maximum modulation mode of the terminal type is 1024QAM modulation, the 1-bit high-level configuration signaling instructs the terminal to use a CQI table with a maximum modulation mode of 64QAM, or to use a CQI table with a maximum modulation mode of 1024QAM.

[0040] In an embodiment of the present invention, the high-level configuration signaling may be a CQI table that directly or indirectly indicates the terminal. For example, the high-level configuration signaling may indicate other information (preset configuration information) to the terminal, but the other information indirectly corresponds to the CQI table of the terminal. For example, for a 1024QAM type terminal, the high-level configuration signaling may indicate whether the terminal enables 1024QAM. If the terminal is indicated to enable 1024QAM, the corresponding terminal uses a CQI table with a maximum modulation mode of 1024QAM. If the terminal is indicated not to enable 1024QAM, the corresponding terminal uses a CQI table with a maximum modulation mode of 64QAM.

[0041] That is to say, optionally, the high-level configuration signaling indicates a CQI table to the terminal, including:

[0042] According to the preset correspondence between the configuration information and the CQI table, the high-layer configuration signaling carrying the configuration information indicates to the terminal the CQI table corresponding to the carried configuration information.

[0043] In the embodiment of the present invention, the MCS table can be configured according to the CQI table, that is, there is a certain correspondence between the MCS table and the CQI table, so that when the high-level configuration signaling indicates a CQI table, it corresponds to an MCS table.

[0044] Based on the above-mentioned embodiments of the present invention and various modified embodiments, a specific embodiment is listed below.

[0045] The method for configuring channel quality indication information in this specific embodiment includes:

[0046] Step 1: The terminal is a 1024QAM terminal type, and the transmitting end selects 2 CQI tables from 3 CQI tables according to the 1024QAM terminal type;

[0047] For example, the transmitting end includes three CQI tables: a CQI table with a maximum modulation mode of 64QAM, a CQI table with a maximum modulation mode of 256QAM, and a CQI table with a maximum modulation mode of 1024QAM.

[0048] The 1024QAM terminal type refers to a terminal whose maximum modulation mode is 1024QAM.

[0049] For another example, for a 1024QAM terminal type, the transmitting end selects a CQI table with a maximum modulation mode of 64QAM and a CQI table with a maximum modulation mode of 1024QAM from three CQI tables.

[0050] In addition, if it is for a 256QAM terminal type, the transmitting end selects a CQI table with a maximum modulation mode of 64QAM and a CQI table with a maximum modulation mode of 256QAM from the three CQI tables.

[0051] Step 2: The transmitting end sends a high-level configuration signaling to the terminal, where the high-level configuration signaling instructs the terminal to use one of the two selected CQI tables.

[0052] Optionally, the high-layer configuration signaling indicating the CQI table for the 1024QAM terminal is 1-bit information, wherein the 1-bit information indicates that the terminal uses the CQI table with a maximum modulation mode of 64QAM or uses the CQI table with a maximum modulation mode of 1024QAM.

[0053] Optionally, the MCS table is configured according to the CQI table, and the MCS table corresponds to the CQI table one by one. For example, when the high-level configuration signaling indicates that the terminal uses a CQI table with a maximum modulation mode of 64QAM, the terminal uses an MCS table with a maximum modulation mode of 64QAM accordingly; when the high-level configuration signaling indicates that the terminal uses a CQI table with a maximum modulation mode of 1024QAM, the terminal uses an MCS table with a maximum modulation mode of 1024QAM accordingly.

[0054] The high-layer configuration signaling may directly or indirectly indicate the CQI table of the terminal. For example, the high-layer configuration signaling may indicate other information to the terminal, but the other information indirectly corresponds to the CQI table of the terminal.

[0065] Wherein, before selecting two CQI tables from a pre-configured channel quality indicator CQI table according to the terminal type of the terminal, the method further comprises:

[0066] According to the terminal type, a maximum modulation mode supported by the terminal is determined.

[0067] In the embodiment of the present invention, optionally, the selected two CQI tables include at least a first CQI table, and a maximum modulation mode of the first CQI table is 64 quadrature amplitude modulation QAM.
