A method for communicating in a communication network, the method comprising: Determining, at a communication device and in connection with a prior uplink multi-user, UL MU, communication in which the communication device participated, whether the communication device is to use i) one or more first channel access parameters or ii) one or more second channel access parameters for accessing a communication medium for a single user, SU, transmission by the communication device, wherein using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters; in response to determining that the communication device is to use the one or more first channel access parameters, using, at the communication device, the one or more first channel access parameters to attempt to access the communication medium; in response to determining that the communication device is to use the one or more second channel access parameters, using, at the communication device, the one or more second channel access parameters to attempt to access the communication medium; and in response to accessing the communication medium, transmitting, with the communication device, the SU transmission via the communication medium; wherein determining whether the communication device is to use i) the one or more first channel access parameters, or ii) the one or more second channel access parameters includes: using, at the communication device, a counter to measure a time period associated with the prior UL MU communication in which the communication device participated; responsive to determining, using the counter, that the time period has not expired, determining that the first communication device is to use the one or more second channel access parameters; and responsive to determining, using the counter, that the time period has expired, determining that the first communication device is to use the one or more first channel access parameters associated with the greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters.
