Managing release of resources for uplink grant-free transmissions on bandwidth part deactivation

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a bandwidth part configuration for a plurality of bandwidth parts, wherein a first bandwidth part of the plurality of bandwidth parts is identified as being activated and is associated with first resources allocated for uplink grant-free transmissions by the UE on the first bandwidth part;
• receiving a first message to deactivate the first bandwidth part;
• and
• receiving a second message to reactivate the first bandwidth part, wherein the second message excludes an indication of second resources allocated for uplink grant-free transmissions on the reactivated first bandwidth part.

A base station for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• transmit, to a user equipment (UE), a bandwidth part configuration for a plurality of bandwidth parts, wherein a first bandwidth part of the plurality of bandwidth parts is identified as being activated and is associated with first resources allocated for uplink grant-free transmissions by the UE on the first bandwidth part;
• transmit a first message to deactivate the first bandwidth part;
• manage the first resources of the deactivated first bandwidth part based at least in part on the bandwidth part configuration, wherein managing the first resources comprises maintaining the first resources for use with the UE;
• and
• transmit a second message to reactivate the first bandwidth part, wherein the second message excludes an indication to the UE of second resources allocated for uplink grant-free transmissions on the reactivated first bandwidth part.
