Embodiment Construction
[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0037] see Figures 1 to 3 , an embodiment of the present invention provides a method for allocating downlink physical shared channel PDSCH resources, the method includes: taking the following configuration scenarios as a column:
[0038] For example, the carrier bandwidth has a total of 273 resource blocks RB (the corresponding resource block RB index is resource block RB0 ~ resource block RB272), and the partial bandwidth BWP1 is 2...

The present invention discloses a resource allocation method for the physical downlink shared channel PDSCH, comprising: obtaining the bandwidth and subband size of the partial bandwidth BWP0 and the partial bandwidth BWP1 in a carrier, and determining the resource allocation mode of the partial bandwidth BWP0 and the partial bandwidth BWP1, according to The downlink service scheduling priority calculates the number of resource blocks RB required for scheduling the user equipment UE, and divides the user equipment UE into user equipment UE with frequency selective gain and user equipment UE without frequency selective gain. Resource allocation is performed for each scheduled user equipment UE activated on the partial bandwidth BWP0, and resource allocation is performed for each scheduled user equipment UE activated on the partial bandwidth BWP1. This method can solve the existing LTE PDSCH resource allocation method It cannot be directly applied to NR, and at the same time, there is no problem in the prior art that there is a resource allocation method that effectively and fully utilizes physical resources and channel frequency selection characteristics, which improves air interface performance and system throughput.
Description
technical field [0001] The present invention relates to the technical field of downlink channel resource allocation, and more particularly to a method for allocating downlink physical shared channel PDSCH resources. Background technique [0002] In NR (New Radio, new air interface), the resource allocation mode of PDSCH (Physical Downlink Shared Channel, downlink physical shared channel) supports two modes of type0 and type1. Type 0 supports non-contiguous resource allocation in units of resource block RBGs (Resource Block Groups). A resource block RBG consists of multiple resource blocks RB. ) is related to the size of the resource block RBG, type1 only supports continuous resource allocation, and the allocation unit is one resource block RB. [0003] Compared with LTE (Long Term Evolution, long term evolution), the NR system becomes more flexible and complex, and one carrier can be configured with multiple partial bandwidth BWPs. In order to make full use of physical res...
