A method for wireless random access, the method comprising: generating a first random number to determine a probability to contend for random access in a wideband communications network using uplink orthogonal frequency division multiple access, hereinafter uplink OFDMA, by a wireless communications device (201, 301); receiving a first frame specifying a second allocated number of resource units, hereinafter RUs, for random access, wherein the first frame carries timing and duration information for the random access RUs; determining whether the device is allowed to contend for random access based on the first random number upon receiving the first frame; updating the first random number and increasing the probability to contend for random access if contention is not allowed, wherein the device waits for subsequent random access; and selecting an RU in accordance with a predetermined rule and transmitting an second frame via the selected RU if contention is allowed, wherein the device (201, 301) re-generates the first random number for subsequent random access; wherein the step of determining whether the device (201, 301) is allowed to contend for random access comprises: comparing the first random number with the second allocated number multiplied by a weighting factor; and characterized in that: the step of updating the first random number thereby increasing the probability to contend for random access if contention is not allowed comprises: subtracting the first random number by the second allocated number multiplied by a weighting factor. generating a first random number to determine a probability to contend for random access in a wideband communications network using uplink orthogonal frequency division multiple access, hereinafter uplink OFDMA, by a wireless communications device (201, 301); receiving a first frame specifying a second allocated number of resource units, hereinafter RUs, for random access, wherein the first frame carries timing and duration information for the random access RUs; determining whether the device is allowed to contend for random access based on the first random number upon receiving the first frame; updating the first random number and increasing the probability to contend for random access if contention is not allowed, wherein the device waits for subsequent random access; and selecting an RU in accordance with a predetermined rule and transmitting an second frame via the selected RU if contention is allowed, wherein the device (201, 301) re-generates the first random number for subsequent random access; wherein the step of determining whether the device (201, 301) is allowed to contend for random access comprises: comparing the first random number with the second allocated number multiplied by a weighting factor; and characterized in that: the step of updating the first random number thereby increasing the probability to contend for random access if contention is not allowed comprises: subtracting the first random number by the second allocated number multiplied by a weighting factor. comparing the first random number with the second allocated number multiplied by a weighting factor; and characterized in that: the step of updating the first random number thereby increasing the probability to contend for random access if contention is not allowed comprises: subtracting the first random number by the second allocated number multiplied by a weighting factor. the step of updating the first random number thereby increasing the probability to contend for random access if contention is not allowed comprises: subtracting the first random number by the second allocated number multiplied by a weighting factor. subtracting the first random number by the second allocated number multiplied by a weighting factor.
