Abstract
The present invention relates to a method for requesting access to a resource, said method comprising a secondary station transmitting an access preamble to a primary station, upon failure of correct transmission of the access preamble, the secondary station starting a first power ramping scheme for transmitting the access preamble, upon failure of correct transmission of the access preamble with the first power ramping scheme, the secondary station transmitting a second access preamble with a second power ramping scheme being different from the first power ramping scheme.
Claims7
A method for requesting access to a resource,
- said method comprising a secondary station transmitting an access preamble to a primary station,
- upon failure of correct transmission of the access preamble, the secondary station starting a first power ramping scheme for transmitting the access preamble,
- upon failure of correct transmission of the access preamble with the first power ramping scheme,
- the secondary station transmitting a second access preamble with a second power ramping scheme being different from the first power ramping scheme.
A secondary station comprising requesting means for requesting access to a resource, said requesting means comprising means for transmitting an access preamble to a primary station, said requesting means being arranged for, upon failure of correct transmission of the access preamble, starting a first power ramping scheme for transmitting the access preamble, and for, upon failure of correct transmission of the access preamble with the first power ramping scheme, transmitting a second access preamble with a second power ramping scheme being different from the first power ramping scheme.
