WIRELESS COMMUNICATION CONTROL METHOD AND WIRELESS COMMUNICATION DEVICE

Abstract

The purpose of the present disclosure is to provide a wireless communication control method and a wireless communication device which make it possible to efficiently avoid noise influence. The wireless communication control method according to the present disclosure comprises: a first step for acquiring reception electric field intensity of a preamble signal received through wireless communication; and a second step for calculating a reception-sensitivity estimated value which is an estimated value for reception sensitivity, on the basis of a reception-sensitivity deterioration amount which is a deterioration amount of reception sensitivity resulting from operation of at least one interface and a wireless frequency for use in the wireless communication; and a third step for controlling operations of interfaces in operation, on the basis of the reception electric field intensity acquired in the first step and the reception-sensitivity estimated value calculated in the second step.

Specification

WE CLAIM:
[Claim 1] A radio communication control method, comprising:
a first process of obtaining a received field strength of a preamble signal received
through radio communication;
5 a second process of calculating a receiving sensitivity estimated value, based on
an amount of receiving sensitivity degradation and a radio frequency to be used in the radio
communication, the receiving sensitivity estimated value being an estimated value of a
receiving sensitivity, the amount of receiving sensitivity degradation being an amount of
degradation in the receiving sensitivity, the degradation being caused by an operation of at
10 least one interface; and
a third process of controlling the operation of the at least one interface being
activated, based on the received field strength obtained in the first process and the receiving
sensitivity estimated value calculated in the second process.
15 [Claim 2] The radio communication control method according to claim 1,
wherein the third process includes deactivating an operation of an interface whose
amount of receiving sensitivity degradation is largest when the receiving sensitivity
estimated value is higher than the received field strength, the interface being included in
the at least one interface being activated.
20
[Claim 3] The radio communication control method according to claim 1,
wherein the third process includes deactivating an operation of an interface whose
priority is lowest when the receiving sensitivity estimated value is higher than the received
field strength, the interface being included in the at least one interface being activated.
25
[Claim 4] The radio communication control method according to any one of claims
1 to 3,
wherein the first process includes obtaining the radio frequency to be used in the
radio communication, and
30 the second process includes calculating the receiving sensitivity estimated value,
based on the radio frequency obtained in the first process and the amount of receiving
sensitivity degradation held in advance.
[Claim 5] The radio communication control method according to any one of claims
1 to 4, comprising
a fourth process of calculating the amount of receiving sensitivity degradation
5 based on a difference between a measurement receiving sensitivity value and a receiving
sensitivity actual value before the first process, the measurement receiving sensitivity value
indicating a receiving sensitivity measured at a varying radio frequency when the at least
one interface is activated, the receiving sensitivity actual value indicating a receiving
sensitivity corresponding to the radio frequency when the at least one interface is not
10 activated.
[Claim 6] The radio communication control method according to any one of claims
1 to 5,
wherein the first process includes estimating the received field strength based on
15 a bit error rate or a packet error rate of the preamble signal received in the first process
after a payload signal is received.
[Claim 7] The radio communication control method according to any one of claims
1 to 6,
20 wherein the third process is executed after completion of receiving a payload
signal.
[Claim 8] A radio communication control method, comprising:
a first process of obtaining a received field strength of a preamble signal received
25 through radio communication; and
a second process of deactivating an operation of an interface whose amount of
receiving sensitivity degradation is largest, based on a received field strength class
determined according to the received field strength obtained in the first process, the amount
of receiving sensitivity degradation being an amount of degradation in a receiving
30 sensitivity, the degradation being caused by the operation of the interface, the interface
being included in interfaces being activated.
[Claim 9] The radio communication control method according to claim 8,
comprising
a third process of calculating the amount of receiving sensitivity degradation based
on a difference between a measurement receiving sensitivity value and a receiving
5 sensitivity actual value before the first process, the measurement receiving sensitivity value
indicating a receiving sensitivity measured at a varying radio frequency when the interface
is activated, the receiving sensitivity actual value indicating a receiving sensitivity
corresponding to the radio frequency when the interface is not activated.
10 [Claim 10] The radio communication control method according to claim 8 or 9,
wherein the second process includes determining the received field strength class
based on the received field strength of the preamble signal received in the first process after
a payload signal is received.
