Abstract:
A scheme for Medium Access Control (MAC) Protocol Data Unit (PDU) signaling includes the steps of receiving, from a Machine-Type Communication (MTC) device, a random access preamble; sending, to the MTC device, a random access response that includes a MAC PDU having a MAC header that includes information for MTC support; receiving, from the MTC device, a scheduled transmission; and performing contention resolution with the MTC device. The information for MTC support can be achieved by: (1) the MAC PDU structure being modified to include a new section used for MTC devices to identify the congestion status of MTC family; (2) providing the backoff control (BOC) with a new sequence of a large-scale backoff interval (BI); (3) changing the random access (RA) procedure for MTC devices; or (4) performing toggling or switching between access class barring (ACB) and backoff control (BOC).
