Abstract
Methods for controlling uplink transmission of data to a network node of a communications system a user equipment node are disclosed. The methods include receiving parameters to configure enhanced uplink in CELL_FACH state, determining whether the user equipment node is able to communicate on an E-DCH in CELL_FACH state and determining whether additional defined conditions have been satisfied, and performing a cell update operation to obtain an E-RNTI value responsive to determining that the user equipment node is not able to communicate on an E-DCH in CELL_FACH state. The methods may also include transmitting uplink data on an E-DCH transport channel to the network node responsive to determining that the user equipment node is able to communicate on an E-DCH in CELL_FACH state and determining that the additional defined conditions have been satisfied. Related user equipment nodes are also disclosed.
