Communication apparatus, information processing apparatus, control method, and storage medium

A control method executed by a communication apparatus that executes communication compliant with IEEE 802.11, the control method comprising:

• receiving, as first receiving, at least part of a first communication frame including information indicating that Special Reuse (SR) is allowed, the first communication frame having been transmitted by a first different communication apparatus;
• detecting a second communication frame that interferes with reception of the first communication frame, the second communication frame having been transmitted by a second different communication apparatus;
• and
• notifying the first different communication apparatus of an error in reception of the first communication frame, based on a signal strength of the signal received by the first receiving and a signal strength of the second communication frame detected by the detecting.

A non-transitory computer-readable storage medium that stores a program that causes, when the program is executed, a communication apparatus to perform:

• receiving, as first receiving, at least part of a first communication frame that includes information indicating that Special Reuse (SR) is allowed, the first communication frame having been transmitted by a first different communication apparatus;
• detecting a second communication frame that interferes with reception of the first communication frame, the second communication frame having been transmitted by a second different communication apparatus;
• and
• notifying the first different communication apparatus of an error in reception of the first communication frame, based on a signal strength of the signal received by the first receiving and a signal strength of the second communication frame detected by the detecting.
