Abstract:
1. A method relating to uplink communications from a wireless terminal to a network over a radio interface, the method implemented in the wireless terminal comprising: detecting data to be transmitted by the wireless terminal to the network to trigger a scheduling request to the network for an uplink transmission; determining a priority associated with the detected data; transmitting an uplink transmission scheduling request to the network if the determined priority is a first priority; delaying transmission or not transmitting an uplink transmission scheduling request to the network if the determined priority is a second different priority, wherein the second priority data corresponds to a data flow configured not to send a scheduling request; determining that a future uplink radio resource is scheduled for use by the wireless terminal, transmitting the data using the future uplink radio resource when the determined priority is the second priority; starting a timer having a predetermined timer value associated with the second priority when the time remaining to the future uplink radio resource equals the predetermined timer value; determining if the timer times out; if the timer times out prior to the data being transmitted, transmitting the uplink transmission scheduling request to the network.
