INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Systems, methods, apparatuses, and computer program products for skipping TB transmission depending on UCI transmission are provided. One method includes receiving, by a UE, a configuration message from a network node. The configuration message may indicate to the UE a configuration of skipping uplink (UL) transmission when there is no uplink data. The method may then include determining whether the UE is requested for uplink control information (UCI) transmission for a subframe with UL grant. If it is determined that the UE is requested for UCI transmission, then the method may include generating and transmitting a transport block containing padding buffer status report (BSR). ## Claims ### Claim at position 1 -28. (canceled) ### Claim 29 A method, comprising: receiving, by a user equipment, a configuration message from a network node, wherein the configuration message indicates to the user equipment a configuration of skipping uplink transmission when there is no uplink data;
