Problems solved by technology

[0006] It can be seen from the above scheme that the biggest problem of this scheme is that it supports a single PRB resource allocation method, which can only support the calculation when the user's BWP is full bandwidth, which seriously hinders the flexibility of resource allocation TYPE-0 scheduling; and based on Therefore, the value of RBG_size is also fixed to 16 PRB sizes. The fixing of multiple parameters causes the base station to only implement a certain fixed scheduling form; in addition, in order to ensure the correct calculation, it is necessary to judge each cycle Whether the PRB index exceeds the limit, which increases the code running time

Embodiment Construction

[0069] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0070] refer to figure 2 , which shows a flow chart of the steps of an embodiment of an index mapping method for a physical resource block PRB according to the present invention, which may specifically include the following steps:

[0071] Step 201, acquire the UE resource status of the user, and determine the parameters of the partial bandwidth BWP of the UE;

[0072] The newly proposed concept of BWP (Bandwidth Part, partial bandwidth) in the communication protocol of the NR system makes RBG (Resource Block Group, resource block group) change from a cell-level parameter to a user-level parameter, which is convenient for UE (User Experience, user experience) Flexible scheduling.

[0073] Specifically, when performing resource ...

Abstract

The embodiment of the invention provides an index mapping method and device for a physical resource block PRB, and the method comprises the steps: obtaining the resource condition of user UE, and determining the parameters of a part of bandwidth BWP of the UE; determining parameters of a resource block group RBG according to the parameters of the BWP; determining a relative index of the RBG and the BWP according to the UE resource condition; and mapping the absolute index of the PRB segment by segment by adopting the parameters of the RBG and the relative index. According to the method, the conversion from the RBG index to the PRB index and the conversion from the PRB index to the absolute PRB index are completed through segmentation mapping, so that a resource mapping error caused by a PRB index calculation error when a service BWP is flexibly configured in a TYPE0 distribution mode is prevented.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an index mapping method of a physical resource block PRB and an index mapping method and device of a physical resource block PRB. Background technique [0002] With the development of the fifth-generation wireless communication technology, 5G will be able to provide users and applications with access to information and data sharing anytime, anywhere, connect all content wirelessly, and provide fast and rich content and services, thereby enriching the people's lives. [0003] At present, the user BWP (Bandwidth Part, partial bandwidth) configured by the MAC layer (Medium Access Control, media access control layer) is all in the form of full bandwidth, so the RBG (ResourceBlock Group, resource block group) index is an absolute index, and the calculation scheme It is relatively simple to implement. It only needs to traverse each RBG according to the RBG index a...
