Abstract:
1. A node of a radio access network comprising: a transceiver configured to facilitate communication with wireless terminals over a radio interface including transmissions on an uplink from the wireless terminals to the node and transmissions on a downlink from the node to the wireless terminals; and a radio resource control unit configured to perform radio resource control functionality including layer three (L3) signaling between the node and the wireless terminals wherein the radio resource control unit comprises: an uplink scheduler configured to make a prediction of a transmission of an uplink L3 message from the wireless terminals to the node and, for a particular wireless terminal for which the prediction is made, to generate, for transmission on the downlink, a grant message which in accordance with the prediction prioritizes a predicted L3 message of the particular wireless terminal relative to messages of others of the wireless terminals, wherein the uplink scheduler is configured to make the prediction based on at least one of a transmission of an evocative downlink L3 message, and a pending buffer size estimation for a buffer of the particular wireless terminal.
