Abstract
Embodiments of the present invention provide a resource allocation method and apparatus, and relate to the communications field. On the premise of existing DMRS pilot overheads, an orthogonal DMRS design method for up to 24 data streams is implemented by means of new port mapping. The solution includes: determining, according to network configuration information, that a quantity of demodulation reference signal DMRS layers of a base station is N; and if 8<N≤12, mapping N DMRS ports corresponding to the quantity of DMRS layers onto three CDM groups on a resource block RB; if 12<N≤24, mapping N DMRS ports corresponding to the quantity of DMRS layers onto six CDM groups on an RB; or if N≤8, mapping N DMRS ports corresponding to the quantity of DMRS layers onto two CDM groups on an RB.
