Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0035] figure 2 It is a diagram for explaining a radio resource allocation method according to an embodiment of the present invention.

[0036] exist figure 2 In the example of , the period during which fixed scheduling is performed (fixed scheduling period) is set to "20ms". That is, it is assumed that voice traffic such as VoIP packets exists every 20 ms.

[0037] One radio section (fixed scheduling period) of fixed scheduling is composed of a plurality of subframes. exist figure 2 In the example of , the size of the subframe is "0.5 ms", and one wireless section (fixed scheduling period) of fixed scheduling is composed of 40 subframes.

[0038] Subframes 11 shown with oblique lines are radio resources for initial transmission that are fixedly allocated by fixed scheduling.

[0039] Seven frames including three subframes before and after the subfram...

Abstract

A radio resource allocation method includes: a step in which a radio base station (10) fixedly allocates a radio resource used when transmitting downlink data to a mobile station by persistent scheduling; and a step B in which the radio base station (10) modifies the radio resource to be allocated to the mobile station by dynamic scheduling during a period while the persistence scheduling is applied.

Description

technical field [0001] The present invention broadly relates to radio communication control technology, and particularly relates to a radio resource allocation method and a radio base station when both persistent scheduling (Persistent Scheduling: fixed allocation scheduling) and dynamic scheduling (Dynamic Scheduling: dynamic allocation scheduling) are used together. Background technique [0002] In a conventional communication system such as High Speed ​​Downlink Packet Access (HSDPA: High Speed ​​Downlink Packet Access), a downlink shared control channel (HS-SCCH: High Speed-Shared Control Channel) is used at every predetermined transmission time interval (TTI: Transmission Time Interval), which transmits allocation information on downlink data transmission opportunities to the mobile station. [0003] However, in some services such as voice communication, it is predetermined that downlink data is sent once every tens of ms, so when using a signaling channel (downlink con...
