本发明的实施例提供一种资源分配方法及装置，涉及通信领域，在现有DMRS导频开销前提下，通过全新端口映射实现多至24数据流的正交DMRS设计方法。该方案包括：根据网络配置信息确定基站的解调参考信号DMRS层数为N；若8＜N《12,则在资源块RB上将与所述DMRS层数对应的N个DMRS端口映射为3个CDM组；若12＜N＜24,则在RB上将与所述DMRS层数对应的N个DMRS端口映射为6个CDM组；若N《8,则在RB上将与所述DMRS层数对应的N个DMRS端口映射为2个CDM组。 The present invention relates to the field of communications. Provided in an embodiment of the present invention are a resource allocation method and device, achieving realizing an orthogonal DMRS design method of up to 24 data streams via a new port mapping, considering thetaking into account existing DMRS pilot overheads. The solution comprises: according to network configuration information, determining as N the number of demodulation reference signal (DMRS) layers of a base station is N; if 8<N≤12, then mapping N DMRS ports corresponding to the number of DMRS layers into 3 code division multiplexing (CDM) groups on a resource block (RB); if 12<N<24, then mapping N DMRS ports corresponding to the number of DMRS layers into 6 CDM groups on the RB; and if N≤8, then mapping N DMRS ports corresponding to the number of DMRS layers into 2 CDM groups on the RB. |
