multiplex the BSR with data of at least one logical traffic channel or data of at least one logical control channel onto a transport block (TB) according to a priority associated with the at least one logical traffic channel or a priority associated with the at least one logical control channel; and
deliver, based on the uplink scheduling allocation, the TB to a physical layer entity of the UE on a transport channel for transmission to a base station.

11. One or more non-transitory computer readable media (CRM) including instructions, wherein execution of the instructions by one or more processors of a base station (BS) is to cause a Media Access Control (MAC) entity of the BS to:
obtain, from a physical layer entity of the BS, a transport block (TB) provided by a user equipment (UE) according to an uplink scheduling allocation;
demultiplex the TB to obtain a Buffer Status Report (BSR) and data of at least one logical transport channel or data of at least one logical control channel, wherein the BSR indicates an amount of data for transmission in an uplink buffer of the UE; and
deliver the demultiplexed BSR and the data of the at least one logical transport channel or the data of the at least one logical control channel to a higher layer entity that is above the MAC entity.
12. The one or more non-transitory CRM of claim 11 , wherein execution of the instructions, is cause the physical layer entity to:
control transmission of an instruction to the UE to transmit the BSR to the BS.
