Abstract:
1. A method for managing transmissions in a wireless communication network, the wireless communication network comprising a plurality of nodes, the method at a first node of the plurality of nodes comprising: transmitting a data frame to a second node of the plurality of nodes using a first transmit power level, wherein the first transmit power level belongs to a set of one or more transmit power levels; determining whether an acknowledgement for the data frame is received from the second node, wherein the acknowledgement for the data frame indicates successful transmission of the data frame to the second node; determining a cause of unsuccessful transmission when the acknowledgement is not received from the second node, wherein the cause of unsuccessful transmission is determined based on a configuration frame received from the second node and wherein the configuration frame is received subsequent to transmitting the data frame; re-transmitting the data frame to the second node using a second transmit power level when the cause of unsuccessful transmission is determined as a collision, wherein the second transmit power level belongs to the set of one or more transmit power levels; and setting a transmit power level to a third transmit power level, wherein the third transmit power level belongs to the set of one or more transmit power levels.
