Access probe acknowledgment including collision detection to avoid oversetting initial power level

A method for supporting wireless communications, the method comprising the steps of:

• detecting that a collision occurs when two or more transmitters attempt to send messages over a first channel, a collision occurring when each of the two or more transmitters transmit messages on the first channel;
• notifying the transmitters of a collision on the first channel by sending a message to the transmitters over a feedback channel;
• adjusting a power output level of a corresponding transmitter attempting to send a message over the first channel depending on whether a collision occurs on the first channel;
• wherein at least a portion of each message transmitted in a time slot overlap, a common encoded sequence of the messages being detectable at a receiver even though there is a collision.

• adjusting a power output level of a corresponding transmitter attempting to send a message over the first channel depending on whether a collision occurs on the first channel;
• wherein a target receiver to which a corresponding message is sent over the first channel sends a feedback message over the shared channel to the transmitters indicating whether a collision occurs on the first channel, the feedback message being sent in a second time slot that is delayed a predetermined amount from a first time slot in which messages are received on the first channel.

A method for supporting wireless communications, the method comprising the steps of:

• allocating a first channel on which multiple transmitters may attempt to send a message;
• dividing the first channel into time slots in which each of the multiple transmitters may attempt to send a message;
• and
• transmitting from each of two or more transmitters a message in a time slot, one part of each message including a common encoded sequence that overlaps during transmission in a time slot so that a device monitoring the first channel can identify a common message type transmission by the two or more transmitters.
