Abstract:
1. A method in a wireless communication system comprising: identifying a set of access preamble sequences used for transmitting a request in a wireless access channel as corresponding to a request for access to transmit an increment of data smaller than a predetermined threshold data size; causing a mobile station having data to transmit of a size smaller than the predetermined threshold size to select one of the access preamble sequences in the identified set for sending an access request, for transmission of said data, to a serving access node via an access channel; and causing the serving access node to allocate a transmission resource for connectionless transmission of said data based on the selected access preamble sequence sent from the mobile station; wherein the identified access preamble sequences are subdivided into multiple sub-groups corresponding to defined granularity in transmission characteristics of the data offered for transmission by the mobile station; wherein access preamble sequences in one of the sub-groups correspond to particular RF conditions existent at the mobile station offering the data for transmission; and wherein a subset of the RF conditions access preamble sequences is established to provide feedback from the mobile station to an access node of the wireless system in respect to RF conditions existent at the mobile station in respect to a paging message from the access node to the mobile station.
