Problems solved by technology

[0017] The purpose of the present invention is to at least solve one of the above-mentioned technical defects. In particular, the base station determines whether the UE has data to be sent by analyzing the received data packets, and solves the problem caused by the base station side and the UE in the uplink scheduling algorithm in the prior art. The problem of data loss caused by the unsynchronized update of the side BO is no longer scheduled for the UE with data

Embodiment Construction

[0034] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention.

[0035] The present invention provides a solution to the problem of no longer scheduling UEs that still have data to be transmitted due to the unsynchronized BO update between the base station side and the UE side in the existing uplink scheduling algorithm. When the BO information maintained by the base station side is not zero, resources are allocated to the UE according to the maintained BO information. When the BO for a certain UE is updated to 0, it is judged whether to continue ...

Abstract

The embodiment of the present invention proposes a method for allocating uplink shared channel resources, including the following steps: the base station receives the buffer status report BSR information sent by the user equipment UE, allocates resources for the UE and receives the service data sent by the UE, and Update the BO value; when the BO maintained by the base station side is 0, the base station judges whether the UE has data to be sent according to the state of the received data block; when judging that the UE also has data to be sent , the base station continues to allocate resources for the UE. The technical solution proposed by the present invention is that the base station analyzes the received data packets to determine whether the UE has data to be sent, and solves the problem of the uplink scheduling algorithm in the prior art due to the out-of-synchronization of BO updates on the base station side and the UE side. The UE of the data is no longer scheduled to cause the problem of data loss.

Description

technical field [0001] The present invention relates to the field of digital communication, and in particular, the present invention relates to a method and device for allocation of uplink shared channel resources. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of 3G systems. The goal is to develop 3GPP wireless access technology towards high data rates, low latency and optimized packet data. Application direction evolution. 3GPP introduced a shared channel mechanism in the LTE (Long Term Evolution) system, and realized the resource sharing of each user and each service in the cell through dynamic resource allocation, so as to realize flexible and efficient use of the system's time domain, frequency domain, airspace resources. [0003] In a mobile communication system, in order to schedule and allocate resources for the user'...
