Abstract
A system, method and apparatus for mobile communications including time sensitive communications is provided. A user equipment (UE) receives a medium access control (MAC) control element comprising a value for calculating a propagation delay (PD) compensation. The UE determines a first timing advance (TA) based on matching a value associated with the first TA with one or more first defined values. The UE determines a PD compensation based on the value. The UE performs a timing synchronization based on the PD compensation and determines an uplink timing based on the first TA. The UE then transmits at least one of an uplink signal or an uplink channel based on the determined timing synchronization and the determined uplink timing.

1-53. (canceled)
A method of time sensitive networking (TSN) communications, comprising:
- receiving, by a user equipment (UE), a medium access control (MAC) control element (CE) comprising a value for calculating a propagation delay (PD) compensation;
- determining a first timing advance (TA) based on the value matching with one or more first values;
- determining a PD compensation based on the value;
- performing a timing synchronization based on the PD compensation;
- determining an uplink timing based on the first TA;
- and
- transmitting at least one of an uplink signal or an uplink channel based on the timing synchronization and the uplink timing.
A method of time sensitive networking (TSN) communications, comprising:
- receiving, by a user equipment (UE), a timing advance (TA) command media access control (MAC) control element (CE) comprising a TA command;
- receiving a signaling message comprising a first value associated with a propagation delay (PD);
- determining a PD compensation based on the TA command and the first value associated with the PD;
- performing a timing synchronization based on the PD compensation;
- determining an uplink timing based on the TA command;
- and
- transmitting at least one of an uplink signal or an uplink channel based on the timing synchronization and the determined uplink timing.
A method of wireless communications, comprising:
- receiving, by a user equipment (UE), a timing advance (TA) command media access control (MAC) control element (CE) with one of a first format or a second format, wherein:
- the TA command MAC CE comprises a TA command;
- the TA command MAC CE is formed with a first format where the TA command has one or more first values;
- and
- the TA command MAC CE is formed with a second format where the TA command has one or more second values;
- determining an uplink timing based on the TA command;
- and
- transmitting at least one of an uplink signal or an uplink channel based on the determined uplink timing.
