INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Various solutions for skipping uplink transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine whether a padding buffer status report (BSR) is included in a protocol data unit (PDU). The apparatus may skip transmission of the PDU when the padding BSR is included in the PDU. The PDU may comprise a medium access control (MAC) PDU. The MAC PDU may comprise no MAC service data unit (SDU). ## Claims ### Claim 1 A method, comprising: determining, by a processor of an apparatus, whether a periodic BSR is included in a PDU; determining, by the processor, whether data is available for a logical channel group (LCG); and skipping, by the processor, transmission of the PDU when the periodic BSR is included in the PDU and no data is available for the LCG. ### Claim 2 (depends on 1) The method of claim 1, wherein the PDU comprises a medium access control (MAC) PDU, and wherein the MAC PDU comprises no MAC service data unit (SDU). ### Claim 3 (depends on 1) The method of claim 1, further comprising: receiving, by the processor, a configured grant; and skipping, by the processor, transmission of the PDU on the configured grant. ### Claim 4 (depends on 1) The method of claim 1, further comprising: transmitting, by the processor, the PDU when the periodic BSR is included in the PDU and the data is available for the LCG, wherein the PDU comprises solely the periodic BSR. ### Claim 5 (depends on 4) The method of claim 4, further comprising: receiving, by the processor, a configured grant; and transmitting, by the processor, the PDU on the configured grant. ### Claim 6 (depends on 1) The method of claim 1, further comprising: receiving, by the processor, a logical channel restriction; determining, by the processor, a restricted logical channel according to the logical channel restriction; determining, by the processor, that data is available in the restricted logical channel; and skipping, by the processor, transmission of the PDU when no data is included in the PDU. ### Claim 7 (depends on 1) The method of claim 1, further comprising: receiving, by the processor, a configuration to enable uplink transmission skipping. ### Claim 8 (depends on 7) The method of claim 7, wherein the configuration is received via a radio resource control (RRC) signaling or a layer 1 (L1) signaling. ### Claim 9 (depends on 1) The method of claim 1, wherein the skipping comprises not generating the PDU. ### Claim 10 An apparatus, comprising: a transceiver capable of wirelessly communicating with a plurality of nodes of a wireless network; and a processor communicatively coupled to the transceiver, the processor capable of: determining whether a periodic BSR is included in a PDU; determining whether data is available for a logical channel group (LCG); and skipping transmission of the PDU when the periodic BSR is included in the PDU and no data is available for the LCG. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the PDU comprises a medium access control (MAC) PDU, and wherein the MAC PDU comprises no MAC service data unit (SDU). ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the processor is further capable of: receiving, via the transceiver, a configured grant; and skipping transmission of the PDU on the configured grant. ### Claim 13 (depends on 10) The apparatus of claim 10, wherein the processor is further capable of: transmitting, via the transceiver, the PDU when the periodic BSR is included in the second PDU and the data is available for the LCG, wherein the PDU comprises solely the periodic BSR. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the processor is further capable of: receiving, via the transceiver, a configured grant; and transmitting, via the transceiver, the PDU on the configured grant. ### Claim 15 (depends on 10) The apparatus of claim 10, wherein the processor is further capable of: receiving, via the transceiver, a logical channel restriction; determining a restricted logical channel according to the logical channel restriction; determining that data is available in the restricted logical channel; and skipping transmission of the PDU when no data is included in the PDU. ### Claim 16 (depends on 10) The apparatus of claim 10, wherein the processor is further capable of: receiving, via the transceiver, a configuration to enable uplink transmission skipping. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein the configuration is received via a radio resource control (RRC) signaling or a layer 1 (L1) signaling. ### Claim 18 (depends on 10) The apparatus of claim 10, wherein, in skipping transmission of the PDU, the processor is capable of not generating the PDU.
