Receiving node, transmitting node, and methods therein for handling channel access

Abstract

A method performed by a transmitting node for handling a channel access for transmitting data to a receiving node is provided. The transmitting node and the receiving node operate in a wireless communications network. The transmitting node obtains a defer list. The defer list comprises nodes causing Signal to Interference Ratio, SIR, below a threshold at the receiver node. The defer list is based on a first defer list received from and created by the receiving node. The transmitting node senses a wireless channel in the wireless communications network. When the transmitting node intends to transmit data to the receiving node, the transmitting node defers channel access to the sensed wireless channel for the data transmission when one or more conditions are fulfilled. The one or more conditions comprise at least that one or more nodes are sensed as communicating and are on the defer list.

Dependencies are inferred from the claim text.
