Method and device for information indication and resource determination and computer storage medium

A method for resource determination, comprising:

• receiving indication information of one or more demodulation reference signal (DMRS) ports resources to be occupied by a terminal from a network side device;
• and
• determining the one or more DMRS ports resources to be occupied by the terminal according to a preset configuration table and the indication information, wherein the configuration table comprises DMRS group information and DMRS port information;
• wherein a DMRS ports designation principle of the configuration table comprises:
• when designating one or more DMRS ports resources to the terminal, setting indexes of respective DMRS ports and respective DMRS groups, respectively, to numbers starting from 0 in an order from least to greatest, and when an index of a DMRS group including one of the one or more DMRS ports to be occupied by the terminal is greater than 0, then defaulting that any DMRS group having an index smaller than the index of the DMRS group including the DMRS port designated to the terminal is to be occupied by the terminal;
• wherein when a DMRS comprises one orthogonal frequency division multiplexing (OFDM) symbol, the maximum number of supported ports is N1, when a DMRS comprises two OFDM symbols, the maximum number of supported ports is N2, and the indexes of the respective DMRS ports and the respective DMRS groups are set to the numbers starting from 0 in the order from the least to the greatest, respectively, then the configuration table comprises one or a combination of following cases:
• case 1:
• when one index of indexes of DMRS ports designated to the terminal is greater than N1−1, then the total number of DMRS ports configured for multi-user multiple-input multiple output (MU-MIMO) transmission is greater than N1, and a DMRS comprises two OFDM symbols;
• case 2:
• when the number of the DMRS ports designated to the terminal is greater than two and no index of the designated DMRS ports is greater than N1−1, then the total number of DMRS ports configured for the MU-MIMO transmission is smaller than or equal to N1 and the DMRS comprises one OFDM symbol.

A device for information indication, comprising:

• a memory configured to store program instructions;
• and
• a processor configured to read the program instructions to perform operations of:
• determining indication information of one or more demodulation reference signal (DMRS) ports resources to be occupied by a terminal according to a preset configuration table, wherein the configuration table comprises DMRS group information and DMRS port information;
• and
• transmitting the indication information to the terminal;
• wherein a DMRS ports designation principle of the configuration table comprises:
• when designating one or more DMRS ports resources to the terminal, setting indexes of respective DMRS ports and respective DMRS groups, respectively, to numbers starting from 0 in an order from least to greatest, and when an index of a DMRS group including one of the one or more DMRS ports to be occupied by the terminal is greater than 0, then defaulting that any DMRS group having an index smaller than the index of the DMRS group including the DMRS port designated to the terminal is to be occupied by the terminal;
• wherein when a DMRS comprises one orthogonal frequency division multiplexing (OFDM) symbol, the maximum number of supported ports is N1, when a DMRS comprises two OFDM symbols, the maximum number of supported ports is N2, and the indexes of the respective DMRS ports and the respective DMRS groups are set to the numbers starting from 0 in the order from the least to the greatest, respectively, then the configuration table comprises one or a combination of following cases:
• case 1:
• when one index of indexes of DMRS ports designated to the terminal is greater than N1−1, then the total number of DMRS ports configured for multi-user multiple-input multiple output (MU-MIMO) transmission is greater than N1, and a DMRS comprises two OFDM symbols;
• case 2:
• when the number of the DMRS ports designated to the terminal is greater than two and no index of the designated DMRS ports is greater than N1−1, then the total number of DMRS ports configured for the MU-MIMO transmission is smaller than or equal to N1 and the DMRS comprises one OFDM symbol.
