Abstract: Method, apparatus and computer program product are configured to operate an electronic device in a wireless communications system to communicate with other electronic devices operative in the wireless communications system; and to establish a radio frame, the radio frame further comprising a radio sub-frame to be used by other electronic devices operating in the wireless communications network, the radio sub-frame having a variable uplink time transmission interval and variable downlink time transmission interval, the variable transmission time intervals implemented with a variable switch point between uplink and downlink timeslots.

Abstract: A radio resource control in an HSUPA system is provided. The control procedure includes: communicating data blocks between user equipment and a network infrastructure over a physical High Speed Uplink Packet Access channel; communicating block acknowledgement messages between the user equipment and the network infrastructure, each block acknowledgement message indicating whether or not a data block was received successfully; and controlling transmission power of the physical HSUPA channel on the basis of at least one block acknowledgement message.
