Methods and systems to perform collision detection (CD) in a communication network are disclosed. Methods and systems over multipacket reception (MPR)-capable physical layers are also disclosed. In one embodiment, the method for transmitting information in a network includes the steps of initiating transmission over a communication channel, monitoring a feedback channel, modifying transmission parameters for the transmission over the communication channel (where modifying includes stopping transmission and adjusting transmission parameters), if a feedback transmission is detected while monitoring the feedback channel, a duration of the feedback transmission being smaller than duration of the transmission over the communication channel, and determining whether transmission was successful, if transmission continues after modifying transmission parameters. Other embodiments of methods for transmitting and receiving information, as well as systems that implement the methods, are also disclosed.
