Problems solved by technology

[0006] However, it is also considered that not all user equipments in the mobile communication system support the semi-persistent scheduling scheme (SPS)
At this time, although the allocation of radio resources is a dynamic scheduling method, in this case, it is necessary to specify radio resources one by one for each voice packet with a small amount of data that is generated periodically, and there is a concern about the above-mentioned problem of increased overhead.
[0007] In addition, there is also a concern that the number of users who can use the voice service is limited due to the increase in overhead.

Abstract

A base station of a communication system includes a quality information retrieval unit that retrieves quality information indicating a radio channel state of user equipment, a threshold value determination unit that determines, for each of the user equipment, a threshold value for at least one of a data retention amount and a data retention time period, depending on the quality information, a scheduler that calculates a scheduling coefficient for the user equipment for which at least the one of the data retention amount and the data retention time period exceeds the threshold value, and that allocates a radio resource to the user equipment at least in accordance with a magnitude of the scheduling coefficient, and a notification unit that reports to the user equipment that the radio resource is allocated.

Description

Technical field [0001] The invention relates to a base station and a scheduling method in a mobile communication system. Background technique [0002] As one of the techniques for improving the frequency utilization efficiency in the mobile communication system, there is frequency scheduling. Frequency scheduling is roughly divided into dynamic scheduling (Dynamic Scheduling) and semi-persistent scheduling (Semi-Persistent Scheduling: SPS). [0003] In the case of the dynamic scheduling method, the wireless resources are dynamically allocated to users according to the priority corresponding to the data type and the state of the wireless channel. For example, every 1ms subframe (TTI) determines which radio resource is allocated to which user. Since the allocation method of wireless resources for users changes frequently, the wireless resources can be used flexibly. [0004] On the other hand, there are various types of data exchanged by users, such as voice packet (VoIP), etc., alt...
