Method and apparatus for determining output transmit power for an access channel in a wireless communication network

A method, comprising:

• obtaining historical information, stored at a wireless device, for a prior access attempt initiated by the wireless device to access a communication network, wherein the historical information for the prior access attempt is determined based on measurements performed only by the wireless device and is not based on measurements sent by the communication network for prior access attempts by the wireless device, and the historical information for the prior access attempt includes a number of access probes sent for the prior access attempt initiated by the wireless device;
• determining a power value based on the historical information for the prior access attempt;
• and
• using the power value for transmission by the wireless device on an access channel for a current access attempt to access the communication network.

A non-transitory processor-readable media storing instructions operable in a wireless device, that when executed, cause the wireless device to:

• obtain historical information, stored at the wireless device, for a prior access attempt initiated by the wireless device to access a communication network, wherein the historical information for the prior access attempt is determined based on measurements performed only by the wireless device and is not based on measurements sent by the communication network for prior access attempts by the wireless device, and the historical information for the prior access attempt includes a number of access probes sent for the prior access attempt initiated by the wireless device;
• determine a power value based on the historical information for the prior access attempt;
• and
• use the power value for transmission by the wireless device on an access channel for a current access attempt to access the communication network.
