Communication Efficiency

Method, comprising:

• detecting, by a second transmit node of a second basic service set, a transmission permission message transmitted from a receive node of a first basic service set to a first transmit node of the first basic service set, wherein the transmission permission message indicates an upcoming data transmission from the first transmit node to the receive node;
• acquiring, based on the transmission permission message, an indication of a basic service set, which is allowed to reuse the same channel as the first transmit node during the data transmission;
• determining, based on the indication, whether the second basic service set is allowed to reuse the same channel as the first transmit node during the data transmission;
• and
• as a response to the determination result, deciding whether or not to attempt transmission on same channel as the first transmit node during the data transmission.

An apparatus, comprising:

• at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause a receive node to perform operations comprising:
• receiving a transmission request message for data transmission from a transmit node of a first basic service set, wherein the transmission request message comprises an indication of a modulation and coding scheme to-be-used in the data transmission;
• detecting signal strength of the transmission request message;
• determining, based on the signal strength and the indicated modulation and coding scheme, a maximum tolerable interference level during the data transmission;
• and
• in response to the transmission request message, generating and sending, to the transmit node, a transmission permission message comprising an indication of the maximum tolerable interference level.
