Abstract:
1. A method of initiating communication between a mobile communication device and a second communication device, comprising: (i) transmitting from the mobile communication device at least a first probe signal on a random access channel by only a first transmit path of the mobile communication device, said first transmit path including a low power amplifier; (ii) determining that acknowledgement is not received from the second communication device in response to said first probe signal; (iii) assessing a power counter to determine when other power settings should be attempted; (iv) determining that a maximum value of the power counter has not been reached; (v) increasing the power counter; and (vi) transmitting from the mobile communication device at least a second probe signal on a random access channel by only a second transmit path of the mobile communication device, said second transmit path including a high power amplifier and said second probe having a power corresponding to the value of the power counter; and (vii) determining that acknowledgement is received from the second communication device and when acknowledgement is not received from the second communication device, repeating steps (iii) through (vi).
