A method for information indication, said method being performed by a network device and comprising: determining (S101) 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 (S102) the indication information to the terminal; the method being characterized in that the configuration table comprises five columns, wherein a first column indicates DMRS configuration indexes, a second column indicates quantities of DMRS configuration layers of the terminal under configurations corresponding to the DMRS configuration indexes, a third column indicates DMRS port indexes corresponding to the quantities of DMRS configuration layers of the terminal, a fourth column indicates DMRS group indexes of DMRS groups including DMRS ports of all terminals in a MU-MIMO system comprising the terminal, and a fifth column indicates the number of allocated DMRS symbols; or the configuration table comprises four columns, wherein a first column indicates DMRS configuration indexes, a second column indicates quantities of DMRS configuration layers of the terminal under configurations corresponding to the DMRS configuration indexes, a third column indicates DMRS port indexes corresponding to the quantities of DMRS configuration layers of the terminal, a fourth column indicates DMRS group indexes of DMRS groups including DMRS ports of all terminals in a MU-MIMO system comprising the terminal, and different DMRS group indexes correspond to different numbers of DMRS symbols. determining (S101) 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 (S102) the indication information to the terminal; the method being characterized in that the configuration table comprises five columns, wherein a first column indicates DMRS configuration indexes, a second column indicates quantities of DMRS configuration layers of the terminal under configurations corresponding to the DMRS configuration indexes, a third column indicates DMRS port indexes corresponding to the quantities of DMRS configuration layers of the terminal, a fourth column indicates DMRS group indexes of DMRS groups including DMRS ports of all terminals in a MU-MIMO system comprising the terminal, and a fifth column indicates the number of allocated DMRS symbols; or the configuration table comprises four columns, wherein a first column indicates DMRS configuration indexes, a second column indicates quantities of DMRS configuration layers of the terminal under configurations corresponding to the DMRS configuration indexes, a third column indicates DMRS port indexes corresponding to the quantities of DMRS configuration layers of the terminal, a fourth column indicates DMRS group indexes of DMRS groups including DMRS ports of all terminals in a MU-MIMO system comprising the terminal, and different DMRS group indexes correspond to different numbers of DMRS symbols. <EOS>
