Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a resource allocation processing method and device.
Background
With the rapid development of communication technology, people put higher and higher demands on communication quality, and therefore, research on allocation overhead and allocation flexibility of resources, which are one of important factors affecting communication quality, is receiving more and more attention.
Under the existing technical conditions, two resource allocation methods are defined in the frequency domain in the current 5G mobile communication system: type 0 and type 1. As shown in fig. 1, type 0 uses a bitmap mode, and bits 0 and 1 indicate whether a resource block group on a downlink subband is allocated to a user, where 1 represents that a certain resource block group on the downlink subband is allocated to the user, and 0 represents that a certain resource block group on the downlink subband is not allocated to the user; the type 1 only supports the continuous allocation of the resource blocks in the frequency domain, and the resource indication value RIV represents the initial position and the length of the resource blocks correspondingly allocated to the user; in addition, there is a resource allocation mode, type 2, and the type 2 mode is basically similar to the type 1 mode, except that the type 2 mode is defined based on the resource block group, and indicates the starting position of the resource block and the length of the resource block. The type 0 mode allows any combination of resource block groups to be used, and supports continuous or discontinuous allocation of the resource block groups on a frequency domain, but the required indicated bit number is more, and the overhead is larger; although the number of indicating bits required by the type 1 method and the type 2 method is the least, the flexibility is not good enough to meet the requirement of resource allocation.
Therefore, it is an important issue to be solved in the industry to provide a resource allocation method for improving the flexibility of resource allocation while ensuring low indication overhead.

However, if the resource allocation method provided by the embodiment of the present invention performs grouping twice, where the first resource partition unit is 4, and the second resource partition unit is 8, the starting position of the resource block allocated to the URLLC service may be RB4, RB8, RB12, or RB16, and when the starting position of the resource block is RB4, two second resource block groups, that is, 16 RBs (RB4, RB5, RB6, RB7, RB8, RB9, RB10, RB11 and RB12, RB13, RB14, RB15, RB16, RB17, RB18, RB19) may be occupied, so as to improve flexibility of frequency domain resource allocation and simultaneously consider resource indication overhead of the system.
