A wire stripper has a blade handle, a gripper handle, a blade jaw and a gripper jaw all pivotally connected at a main pivot pin that is offset from the mating faces of the jaws.

A blade hold down spring urges the blades into alignment. The jaws are angled with respect to the handle axis so the throat of the cutting blades aligns with a user's line of sight. Individual handle springs have differential springs rates and are arranged so that the handles springs do no resist opening of the jaws.

Aspects are provided allowing for selective monitoring of uplink cancellation indication (ULCI) occasions by UEs and allowing UEs to determine from ULCI whether canceled uplink transmission are carried on non-supplementary uplink (NUL) carriers or supplementary uplink (SUL) carriers.

The base station may configure blocks in downlink control information to indicate the UE should apply ULCI to SUL and / or NUL. The base station may configure the UE to perform different behaviors after receiving a ULCI depending on whether the portion of the uplink transmission to be canceled is on SUL or NUL.
