Problems solved by technology

At this time, the base station can determine the direction of the mobile station if it receives a signal from the mobile station, but the timing at which the mobile station under DRX control transmits a signal is uncertain, so the base station cannot determine the direction of the mobile station under DRX control. direction

Embodiment approach 1

[0032] figure 1 It is a diagram showing the configuration of the mobile communication system according to Embodiment 1 of the present invention. The mobile communication system 100 includes a base station 1 and a mobile station 5 . The mobile communication system 100 is a wireless communication system based on communication standards for mobile communication. The base station 1 is capable of wireless communication with the mobile station 5 , and is capable of communicating with other not-shown base stations, higher-level devices, and the like, and the base station 1 relays data transmitted from the mobile station 5 to other devices. The mobile station 5 is a mobile phone, a tablet terminal, or the like, and is a portable information processing terminal that a user carries and can move. figure 1 One mobile station 5 is shown in , however, the present invention is not limited to this example, and the base station 1 can communicate with a plurality of mobile stations 5 . The n...

Embodiment approach 2

[0065] Figure 7 It is a diagram showing the operation of the mobile communication system according to Embodiment 2 of the present invention. The configuration of the mobile communication system 100 of Embodiment 2, the configuration of the base station 1, and the configuration of the mobile station 5 are related to Figure 1~3 The structure of Embodiment 1 shown is the same, and therefore description thereof will be omitted here. Hereinafter, differences from Embodiment 1 will be mainly described.

[0066] The operation of generating transmission data (step S101), and distributing the preamble 11 to the mobile station 5 by the distributing unit 107 (step S102) is the same as that of the first embodiment. The start request signal generation unit 111 generates a start request signal 15 including timing information indicating the timing at which the mobile station 5 transmits the preamble 11 to the base station 1 in addition to the preamble information indicating the assigned ...

Embodiment approach 3

[0073] In the above second embodiment, the base station 1 transmits the start request signal 15 to a specific mobile station 5, however, in this embodiment 3, it is possible to perform non-contact with a plurality of mobile stations 5 with one start request signal. Competing synchronization processing.

[0074] The configuration of the mobile communication system 100 of Embodiment 3, the configuration of the base station 1, and the configuration of the mobile station 5 are the same as those of Embodiments 1 and 2, and operations such as setting the direction of the directional beam 2 are the same as those of Embodiment 2, so descriptions thereof are omitted here. . Hereinafter, the configuration of the start request signal, which is a point of difference from Embodiment 2, will be mainly described.

[0075] Figure 10 It is a diagram showing the structure of a start request signal transmitted from the base station 1 to the mobile station according to the third embodiment. ...

Abstract

A base station (1) that communicates with a mobile station (5) that intermittently performs a reception operation during a periodic reception period is characterized in that it has: an allocation unit (107) that allocates a preamble to the mobile station (5); a request signal generating section (111) that generates a start request signal including a preamble assigned to a mobile station (5) and requesting to start a synchronization process between the mobile station and the base station; and a beam control section (105), It transmits the start request signal in a plurality of directions while switching the direction of the directional beam (2) that transmits the start request signal during the reception period, and upon receiving the preamble transmitted by the mobile station (5) that has received the start request signal The direction of the directional beam determines the direction of the directional beam when communicating with the mobile station (5).

Description

technical field [0001] The present invention relates to a base station, a mobile station and a communication method for communicating using directional beams. Background technique [0002] In the 5th generation mobile communication system, in order to expand the frequency band to be used, it is assumed to use high-frequency radio waves called millimeter waves. Radio waves in the high frequency band are prone to attenuation. Therefore, a method has been proposed that uses a directional antenna to form a high-gain directional beam to compensate for radio wave attenuation and improve communication quality between a base station and a mobile station. In such a system, since the range in which communication can be performed with one directional beam is narrow, communication is performed by directing the direction of the directional beam toward the direction in which the mobile station is located. Hereinafter, the range in which communication can be performed with one directiona...
