Embodiment Construction

[0047] Next, the best mode for carrying out the present invention will be described based on the following examples with reference to the drawings.

[0048] In addition, in all the drawings for explaining the embodiments, components having the same function are assigned the same reference numerals, and repeated descriptions are omitted.

[0049] refer to figure 2 A communication system in an embodiment of the present invention will be described.

[0050] The communication system (wireless access network) assumed in this embodiment consists of a plurality of transmission devices 100 (100 1 、100 2 、100 3 ), the radio network controller 200 connected with the sending device 100, the receiving device 300 (300 1 、300 2 、300 3 、300 4 、300 5 、300 6 )constitute. The transmitting device 100 has a channel allocation device.

[0051] The communication system forms a service area (a cell in the case of wireless communication) so that information can be exchanged between the tr...

Abstract

A logical channel is configured by a control logical channel and a data transmission logical channel. A radio physical channel can be shared by a plurality of logical channels. One logical channel corresponds to one radio physical channel. A channel allocation device includes traffic monitoring detection means for detecting occurrence of a traffic of the logical channel and logical channel allocation means for successively allocating necessary resources on the radio physical channel in accordance with occurrence of the traffic of the logical channel.

Description

technical field [0001] The present invention relates to a channel allocation device and a channel allocation method, in particular to a technology for dynamically allocating required resources on the wireless physical channel under the condition that the logical channel and the wireless channel have a corresponding relationship. Background technique [0002] A channel allocation method in W-CDMA will be described (for example, refer to Non-Patent Documents 1 and 2). [0003] In W-CDMA, such as figure 1 As shown, three functional channels are prepared: the functional channel defined between RLC-MAC is the logical channel (Logical Channel), the functional channel defined between MAC-Physical is the transport channel (Transport Channel), and the functional channel defined between the Physical The physical channel (Physical Channel) of the functional channel defined by the layer. [0004] Logical channels are composed of BCCH, PCCH, CCCH, MCCH, DCCH, MSCH, MTCH, DTCH, etc. CCH...
