    摘要: A wireless device may receive a message indicating that it is to switch cells, such as in a handover process, and the wireless device may take steps to switch cells. The time needed for making the switch can depend on, for example, the time it takes the wireless device to process that message, and different types of messages (e.g., messages at a media access control—MAC—layer) may be processed more quickly than others. A wireless device may quickly cancel a triggered power headroom report (PHR) procedure for an old cell, and trigger a PHR for a new cell, based on receiving such a message. The canceling and/or triggering may be performed even without resetting a MAC entity of the wireless device.
