SYSTEMS AND METHODS FOR TRIGGERING MAC CE FOR MEASUREMENT GAP

Systems and methods for triggering Medium Access Control (MAC) Control Element (CE) for measurement gap are provided. In some embodiments, a method performed by a User Equipment (UE) for requesting gap status change includes: generating a MAC CE that indicates a preference for a Measurement Gap (MG) state; receiving an indication from base station granting permission to the UE to trigger a scheduling request; acquiring an uplink grant by triggering a scheduling request; and after acquiring the uplink grant, transmitting the MAC CE that indicates a preference for a MG state. In this way, the UE can dispatch the MG activation/deactivation with a very low latency; i.e., as soon as the MAC CE are available; the availability of MG MAC CE can also trigger transmission; sending SR and obtaining grant to send the MAC CE. A 0 common MAC CE design for measurement gap activation/deactivation and BSR saves latency and reduces overhead.
