Problems solved by technology

[0012] However, it is a problem in the following Patent Document 1, and there is a problem that when a common channel is used as a reservation area, collisions of reservation packets frequently occur, and the data transfer efficiency decreases.
[0015] In the technologies proposed in the following patent documents 2 to 3, although the occurrence of conflicts in reservation groups can be reduced, the occurrence of conflicts cannot be eliminated
Therefore, a reduction in data transfer efficiency cannot be avoided

Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0048] FIG. 1 is a block diagram showing the configuration of main parts of a wireless communication system as an embodiment of the present invention. The wireless communication system shown in FIG. The base station 2 to be visited performs access from the wireless terminal 1 to the base station 2 (uplink) through the "reserved random access method", that is, a plurality of terminals 1 randomly transmit data to the base station 2 using the wireless resource ( communication channel) reservation request.

[0049] Moreover, as shown in FIG. 1 , when focusing on its main parts for description, the wireless terminal 1 is configured to include a transmitting unit 11, a receiving unit 12, a wireless resource management unit 13, a terminal state management unit 14, a buffer 15, a reserved area application 16, transmission reservation control unit 17, and data transmission cont...

Abstract

The invention provides a radio communication system, a base station and terminals used in the system. In the radio communication system, a plurality of terminals (1) which perform reservation request for radio resources (6) which are necessary for data transmission to the base station (2) at random, wherein terminals (1) are allocated with inherent radio resources (5) for reservation request which are necessary for the terminals (1) to perform the reservation request to the base station (2). As a result, the collision occurrence of reservation requests is eliminated.

Description

technical field [0001] The present invention relates to a wireless communication system, a base station and a terminal used in the system, and particularly relates to a technology suitable for packet communication, especially packet communication using wireless from a terminal to a base station (uplink). Background technique [0002] In a wireless communication system, when performing communication in the direction (uplink) from a mobile terminal (MS: Mobile Station) to a base station (BS: Base Station) A method of performing communication using an occupied wireless resource (communication based on an independent channel), and a method of communicating using the same wireless resource shared by all terminals (communication based on a common channel). [0003] When communication is performed using an independent channel, since resources occupied by each terminal are secured, it is not affected by other terminals. [0004] However, when the amount of data to be communicated i...
