[0046] figure 1 The structure of the communication device in the first embodiment is shown.

[0047] The communication device 100 uses a plurality of radio resources. In this specification, a group of wireless resources including a plurality of wireless resources used by the communication device 100 is referred to as a wireless resource group. Here, these wireless resources may be wireless resources having at least a predetermined frequency bandwidth. For example, radio resources may be resource blocks divided into time domain and frequency domain. Radio resources may also be resource blocks with a three-dimensional structure including time, frequency and space domains (eg, antenna selection). Furthermore, resource blocks having this three-dimensional structure are implemented by multiple-input multiple-output (MIMO). In addition, a resource block may also be a radio resource having a three-dimensional structure including time, frequency, and code. The radio resource hav...

[0054] figure 2 The structure of the communication device in the second embodiment is shown.

[0055] The communication device 200 uses a plurality of radio resources. A group of wireless resources including a plurality of wireless resources used by the communication device 200 is called a wireless resource group.

[0056] The communication device 200 has at least a comparison unit 10 , a determination unit 20 , and an assignment unit 30 . The comparing section 10 and the judging section 20 are as described in the first embodiment. The judging section 20 in this embodiment outputs information indicating whether or not interference has occurred at the radio resource compared by the comparing section 10 as a judgment result. The assignment section 30 inputs the judgment results, and assigns wireless resources to other communication devices based on these judgment results.

[0057] Next, the operation of the communication device 200 in this embodiment will be described.

[0064] image 3 A communication device in the third embodiment is shown.

[0065] The communication device 300 uses multiple radio resources. A group of wireless resources including a plurality of wireless resources used by the communication device 300 is called a wireless resource group.

[0066] The communication device 300 has at least a comparison unit 10 , a determination unit 20 , a calculation unit 25 , and a distribution unit 35 . The comparing section 10 and the judging section 20 are as described in the first embodiment. The judging section 20 in this embodiment outputs information indicating whether interference occurs at the radio resource compared by the comparing section 10 and information indicating a value of interference occurring at the compared radio resource as a judgment result. The calculation unit 25 calculates an average value of the interference power of a plurality of radio resources included in the radio resource group based on the determination r...

Abstract

Provided is a more appropriate determination method in determining radio resources with which interference has occurred. According to an aspect of the invention, a communication apparatus, which uses a radio resource group including a plurality of radio resources, comprises: a comparison means that makes mutual comparison of the interference powers of at least two of a plurality of radio resources; and a determination means that determines, on the basis of a result of the comparison made by the comparison means, whether interference has occurred with the radio resources compared by the comparison means.

Description

technical field [0001] The present invention relates to a communication device, a communication system, a control method, and a storage medium for storing a communication program for appropriately judging a wireless resource in which interference has occurred. Background technique [0002] Generally, a radio base station allocates radio resources to a radio terminal and performs radio communication with the radio terminal. Radio waves are used in wireless communications, which may cause interference. Interference is a state in which multiple radio waves overlap and these radio waves become different when transmitted individually. For example, in a case where two different radio base stations each use the same radio resource in radio communication, interference may occur at the radio resource. [0003] An example of a method for judging whether or not interference occurs at a specific wireless resource in wireless communication is the judging method described in Patent Docu...
