Problems solved by technology

[0009] To sum up, the existing eNodeB MAC layer scheduling algorithm adopts RB-based time-domain priority sorting, and the processing of the cross-layer merging algorithm is performed inside the frequency-domain scheduling module, which involves the processing of two priority queues of RB and UE Operations such as pre-estimation of the total number of RBs participating in frequency-domain scheduling increase the processing complexity of the frequency-domain scheduling module, and the efficiency of resource allocation is low, which is not conducive to the realization of MAC layer products of eNodeB

Abstract

The invention discloses a resource allocation method and device, which are used to reduce the calculation amount required for resource allocation, thereby improving resource allocation efficiency. A resource allocation method provided by the present invention includes: determining the UE that currently needs to allocate frequency domain resources according to the priority weight of each user equipment UE, wherein the priority weight of the UE is based on the radio bearer corresponding to the UE The priority value of the RB is determined; the frequency domain resources are allocated to UEs that currently need to allocate frequency domain resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and device. Background technique [0002] In the Long Term Evolution (LTE) system, the Media Access Control (Multiple Access Control, MAC) layer of the evolved NodeB (eNodeB) needs to perform scheduling for the User Equipment (UE) in each subframe and resource allocation operations, so for the implementation of eNodeB products, there is an increasingly prominent contradiction between the limited computing power of the MAC layer scheduler and the huge computing requirements. [0003] The LTE standard stipulates that the MAC layer of the eNodeB implements the scheduling function, and defines two scheduling algorithms: dynamic scheduling and semi-persistent scheduling. Currently, the standard only defines the signaling used for air interface transmission. degree of freedom; on the other hand, it also puts forward higher requirements on ...
