FIELD: radio engineering and communications.
SUBSTANCE: invention relates to communication, inventions provide a method and a resource allocation device. Solution includes: determining according to the network configuration information that the number of levels of the demodulation reference signal (DMRS) of the base station is N; and if 8 < N ≤ 12, the distribution of N DMRS ports corresponding to the number of DMRS levels, into three CDM groups on the resource block RB; if 12 < N ≤ 24, the distribution of N DMRS ports corresponding to the number of DMRS levels, into six CDM groups per RB; or, if N ≤ 8, the distribution of N DMRS ports corresponding to the number of DMRS levels, into two CDM groups per RB.
EFFECT: in the amount of existing pilot DMRS resource costs using the new port allocation, an orthogonal synthesis method (DMRS) is performed for 24 or less data streams.
