A user equipment device (UE) may transmit, in a packet to a base station, information associated with resource configuration/resource requirement corresponding to wireless uplink communications of the wireless communication device. The base station may assign resources to the UE based on the received information. The UE may receive an uplink grant from the base station, with the uplink grant specifying resources for use by the wireless communication device during the uplink communications based on the information previously transmitted to the base station by the wireless communication device. The UE may send the packet at the time a voice call with the UE is initiated, and/or the UE may transmit the information during voice calls in response the UE changing one or more resource configuration parameters during the voice call. The UE may use Robust Header Compression packets of various types to transmit the resource configuration information.
