The present invention selects the logical channels related to the UL grant among logical channels not related to a suspended radio link control (RLC) entity among RLC entities configured in the communication or processing device. ## Claims ### Claim 1 A communication device for transmitting uplink (UL) data in a wireless communication system, the communication device comprising: a transceiver, and a processor configured to control the transceiver, the processor configured to: select logical channels related to an UL grant; allocate resources of the UL grant to the selected logical channels; and control the transceiver to transmit UL data of the selected logical channels on the UL grant, wherein the processor is configured to select the logical channels related to the UL grant among logical channels not related to a suspended radio link control (RLC) entity among RLC entities configured in the communication device. ### Claim 2 (depends on 1) The communication device according to claim 1, wherein the processor is configured to: allocate the resources of the UL grant to the selected logical channels in a predefined order of priority. ### Claim 3 (depends on 1) The communication device according to claim 1, wherein the processor is configured to: perform selecting of the logical channels related to the UL grant and allocating of the resources of the UL grant at a medium access control (MAC) entity configured in the processor. ### Claim 4 (depends on 1) The communication device according to claim 1, wherein a logical channel related to the suspended RLC entity comprises a logical channel related to a suspended radio bearer, a logical channel related to an RLC entity in which a maximum number of retransmissions has been reached, a logical channel related to an RLC entity perform RLC re-establishment, or a logical channel related to a packet data convergence protocol (PDCP) entity performing PDCP re-establishment. ### Claim 5 A processing device comprising: at least one processor; and at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising: selecting logical channels related to an uplink (UL) grant; allocating resources of the UL grant to the selected logical channels; and transmitting UL data of the selected logical channels on the UL grant, wherein the operations select the logical channels related to the UL grant among logical channels not related to a suspended radio link control (RLC) entity among RLC entities configured in the processing device. ### Claim 6 (depends on 5) The processing device according to claim 5, wherein the operations comprises: allocating the resources of the UL grant to the selected logical channels in a predefined order of priority. ### Claim 7 (depends on 5) The processing device according to claim 5, wherein the operations comprises: performing selecting of the logical channels related to the UL grant and allocating of the resources of the UL grant at a medium access control (MAC) entity configured in the processing device. ### Claim 8 (depends on 5) The processing device according to claim 5, wherein a logical channel related to the suspended RLC entity comprises a logical channel related to a suspended radio bearer, a logical channel related to an RLC entity in which a maximum number of retransmissions has been reached, a logical channel related to an RLC entity perform RLC re-establishment, or a logical channel related to a packet data convergence protocol (PDCP) entity performing PDCP re-establishment. ### Claim 9 A method for transmitting, by a communication device, uplink (UL) data in a wireless communication system, the method comprising: selecting logical channels related to an UL grant; allocating resources of the UL grant to the selected logical channels; and transmitting UL data of the selected logical channels on the UL grant, wherein the logical channels related to the UL grant are selected among logical channels not related to a suspended radio link control (RLC) entity among RLC entities configured in the communication device. ### Claim 10 (depends on 9) The method according to claim 9, wherein the resources of the UL grant are allocated to the selected logical channels in a predefined order of priority. ### Claim 11 (depends on 9) The method according to claim 9, wherein selecting the logical channels related to the UL grant and allocating the resources of the UL grant is performed at a medium access control (MAC) entity configured in the communication device. ### Claim 12 (depends on 9) The method according to claim 9, wherein a logical channel related to the suspended RLC entity comprises a logical channel related to a suspended radio bearer, a logical channel related to an RLC entity in which a maximum number of retransmissions has been reached, a logical channel related to an RLC entity perform RLC re-establishment, or a logical channel related to a packet data convergence protocol (PDCP) entity performing PDCP re-establishment.
