Methods and apparatus for switching between bandwidth parts

An apparatus comprising:

• a processor;
• and
• a non-transitory processor-readable storage medium storing instructions for execution by the processor, the instructions causing the processor to perform a method comprising:
• receiving control signaling in a scheduling slot of a scheduling bandwidth part (BWP), wherein the control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the apparatus,
• wherein the control signaling aligns with a time unit boundary associated with the scheduling BWP,
• wherein the control signaling indicates a plurality of slots scheduled for data transmission or reception in the second active BWP or the second active BWP pair,
• wherein the control signaling indicates an earliest slot in the plurality of slots using a non-negative integer K0, and wherein K0=0 corresponds to a slot of the second active BWP or the second active BWP pair which includes a control signaling monitoring occasion based on a control signaling monitoring periodicity of the second active BWP or the second active BWP pair and is on or after a boundary of the scheduling slot plus a transition time from the first active BWP to the second active BWP or from the first active BWP pair to the second active BWP pair.

A method comprising:

• transmitting, by a network equipment, control signaling to a user equipment (UE) in a scheduling slot of a scheduling bandwidth part (BWP), wherein the control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE,
• wherein the control signaling aligns with a time unit boundary associated with the scheduling BWP,
• wherein the control signaling indicates a plurality of slots scheduled for data transmission or reception in the second active BWP or the second active BWP pair,
• wherein the control signaling indicates an earliest slot in the plurality of slots using a non-negative integer K0, and
• wherein K0=0 corresponds to a slot of the second active BWP or the second active BWP pair which includes a control signaling monitoring occasion based on a control signaling monitoring periodicity of the second active BWP or the second active BWP pair and is on or after a boundary of the scheduling slot plus a transition time from the first active BWP to the second active BWP or from the first active BWP pair to the second active BWP pair.
