Abstract
Method, apparatus, and computer program product example embodiments enable contention for access to a wireless communications medium. In example embodiments, a method comprises initiating a channel access procedure by an apparatus; performing, by the apparatus, in response to the channel access procedure initiation, a random draw for permission to start contention with other member apparatuses of a group in which the apparatus belongs, the random draw being based on how many member apparatuses of the group are expected to compete for the wireless communications medium; and starting, by the apparatus, contention for access to the wireless communications medium, if the apparatus wins the random draw.
