Embodiment Construction

[0058] Dynamic scheduling can flexibly handle real-time services and non-real-time services, and semi-static scheduling can handle Voip services and services that generate small data packets and are periodically generated. The combination of the two scheduling and multiplexing processing mechanisms will realize downlink for the base station A method is provided.

[0059] The present invention is a joint processing mechanism based on multiplexing and downlink scheduling in the MAC layer of the LTE system. Different services adopt different scheduling processes. After the processing is completed, the scheduling results are sent to the multiplexing, and the multiplexing performs grouping and other processing. , for the uplink multiplexing of the UE, since the uplink scheduling is in the base station (eNODEB), calculate according to the buffer status report (BSR) indication and inform the base station of the resource block (RB) number of each UE that needs uplink scheduling and st...

Abstract

The invention relates to the technical field of wireless communication and provides an appropriate cooperative handling mechanism and a new base station downlink method in order to achieve joint scheduling in LTE and provide key technical support for improvement of implementation efficiency of an LTE base station. Thus, according to the technical scheme, the method for jointly handling multiplexing and scheduling in a media access control layer of a long-term evolution system includes the step that UE allocates resources to all services through a token bucket algorithm according to a base station uplink scheduling instruction and is characterized in that the method further includes the process of joint handling of dynamic and semi-static scheduling in downlink scheduling and downlink multiplexing and the process of secondary allocation of resources in downlink scheduling, and the handling process relates to a downlink dynamic scheduling module, a semi-static module and a multiplexing module. The method is mainly applied to wireless communication occasions.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and relates to a multiplexing and scheduling joint processing method and a scheduling secondary allocation method in a long-term evolution (LTE) system, specifically, to a multiplexing and scheduling joint processing method in a medium access control layer of a long-term evolution system. technical background [0002] The main goals of LTE include: reducing time delay, increasing user data rate, improving system capacity and coverage, and reducing operator costs. Due to the complexity of spectrum allocation, LTE needs to be able to flexibly allocate spectrum and efficiently transmit data on the allocated spectrum. The flexibility of LTE spectrum can be seen from the supported bandwidth allocation methods (6 methods from 1.4MHz to 20MHz are supported). The LTE physical layer uses new technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input M...
