Logical channel (LCH) may be multiplexed together based on one or more latency requirements. Mapping of LCH(s) to spectrum operating mode(s) (SOM(s)) may be based on SOM capability and/or LCH requirements. A WTRU may determine mapping based on one or more pre-defined rules. The mapping may be based on one or more requirements for the various type of traffic and/or SOM capabilities. A radio bearer may be mapped to one or more SOMs. The WTRU may be configured with a set of SOMs, for one or more, or each, radio bearer. The WTRU may dynamically determine, for example based on radio conditions, buffer status and/or other parameters, the SOM to use. Incompatible multiplexing of LCH may be reduced and/or avoided, perhaps based on using one or more transport blocks (TBs) mapped to the same physical layer (PHY). Traffic may be prioritized based on one or more latency requirements.
