Abstract

The invention discloses a PDSCH resource allocation method, which comprises the following steps of: acquiring bandwidths and sub-band sizes of a part of bandwidth BWP0 and a part of bandwidth BWP1 in a carrier, determining a resource allocation mode of the part of bandwidth BWP0 and the part of bandwidth BWP1, calculating the number of RBs required for scheduling UE according to a downlink service scheduling priority, and dividing the UE into the UE with the frequency selection gain and the UE without the frequency selection gain. According to the resource allocation method, resource allocation is carried out on each piece of scheduled user equipment UE activated on a part of bandwidth BWP0, and resource allocation is carried out on each piece of scheduled user equipment UE activated on a part of bandwidth BWP1. The resource allocation method can solve the problem that an existing resource allocation method of PDSCH of LTE cannot be directly applied to NR; meanwhile, the problem that a resource allocation method for effectively and fully utilizing physical resources and fully utilizing channel frequency selection characteristics does not exist in the prior art is solved, the air interface performance is improved, and the system throughput is further improved.

Description

technical field [0001] The present invention relates to the technical field of allocation of downlink channel resources, and more specifically relates to a resource allocation method of a physical downlink shared channel PDSCH. Background technique [0002] In NR (New Radio, new air interface), the resource allocation mode of PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) supports two modes of type0 and type1. Type 0 supports discontinuous resource allocation in units of resource block RBG (Resource Block Groups, resource block group). A resource block RBG is composed of multiple resource block RBs. The number of resource block RBs is related to the partial bandwidth (bandwidth part, partial bandwidth BWP ) is related to the size of resource block RBG, type1 only supports continuous resource allocation, and the allocation unit is 1 resource block RB. [0003] Compared with LTE (Long Term Evolution, long-term evolution), the NR system has become m...
