Abstract:
1. A method in a wireless terminal relating to uplink communications from the wireless terminal to a network over a radio interface, wherein the wireless terminal stores data to be transmitted to the network in a buffer, the method comprising: detecting data to be transmitted by the wireless terminal to the network; determining a priority associated with the detected data; determining that a future uplink radio resource is scheduled for use by the wireless terminal; transmitting an uplink transmission scheduling request to the network if the determined priority is a first priority; transmitting the data using the future uplink radio resource when the determined priority is the second priority; detecting that the buffer is empty; thereafter, detecting that the buffer has received data for transmission; if the detected data is associated with the first priority, transmitting a scheduling request, generating a buffer status report, receiving an uplink scheduling grant from the network, and transmitting the data with the first priority and the buffer status report to a the network; and if the detected data is associated with the second priority, not transmitting a scheduling request, a buffer status report is not transmitted to the network until an uplink resource is available to transmit the detected data associated with the second priority.
