Apparatus, system and method of communicating an authentication request frame
First Claim
1. An apparatus comprising:
- a memory; and
a processor configured to cause a wireless station to;
set a maximum transmission interval value;
initialize a transmission interval to a minimum transmission interval value;
select a first random number with an upper limit based on the transmission interval;
select a beacon interval based on the selected first random number;
select a second random number with an upper limit based on a number of slots in the beacon interval;
select a slot within the selected beacon interval based on the selected second random number;
trigger transmission of an authentication request frame within the selected slot of the selected beacon interval; and
increase the transmission interval based at least on an unsuccessful transmission of the authentication request frame.

Abstract
Improved collision-avoidance techniques for a wireless communications system are described. In various embodiments, for example, an apparatus may comprise a processor circuit, a determination component for execution by the processor circuit to determine a current transmission interval comprising a series of beacon intervals, each of the series of beacon intervals comprising a plurality of time slots, randomly select one of the series of beacon intervals, and randomly select one of the plurality of time slots within the selected beacon interval, and a communications component for execution by the processor circuit to send a join request during the selected time slot. Other embodiments are described and claimed.

19. An apparatus comprising:
-
a memory; and a processor configured to cause an Access Point (AP) to; access an authentication request frame received within a slot of a beacon interval, the slot is based on a first random number bounded by an upper limit of a number of slots in the beacon interval, the beacon interval is based on a second random number bounded by an upper limit of a transmission interval; trigger transmission of an acknowledgement to a wireless station (STA) to indicate receipt of the authentication request frame in response to receipt of the authentication request frame; access another authentication request frame from another wireless station; and trigger transmission of another acknowledgement to the another wireless station. - View Dependent Claims (20, 21, 22)
