Grant based and configured grant based pusch transmissions in an unlicensed spectrum

A method, comprising:

• receiving, by a user equipment (UE) and from a source device associated with a source cell, configuration data;
• determining, by the UE and based on the configuration data, a starting position for transmitting data in multiple slots in a Physical Uplink Shared Channel (PUSCH) within a shared channel occupancy time (COT), wherein the starting position depends on a first listen before talk (LBT) outcome;
• performing, by the UE, the first LBT;
• and
• transmitting, by the UE, the data at the starting position in an available slot of the COT.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a user equipment (UE), cause the UE to perform operations, the operations comprising:

• receiving, from a source device associated with a source cell, configuration data;
• determining, based on the configuration data, a starting position and ending position for transmitting data in multiple slots in a Physical Uplink Shared Channel (PUSCH) within a shared channel occupancy time (COT), wherein the starting position depends on a first listen before talk (LBT) outcome;
• performing the first LBT at a first symbol of an available slot of the shared COT;
• and
• transmitting the data at the starting position in the available slot of the shared COT.
