摘要:
A method for controlling delay tolerant access of a Machine-Type Communication (MTC) device based on a backoff mechanism is provided. The method includes receiving, at a terminal, a paging message including an access barring information update indicator from a base station, and receiving a System Information Block (SIB) including updated access barring information, the SIB being received regardless of modification periods. The terminal receives the SIB including the updated access barring information immediately without waiting for the arrival of next modification period, resulting in improvement of access barring efficiency.

A method of receiving data by a terminal which supports a Multimedia Broadcast Multicast Service "MBMS" is presented. The method comprises detecting (510), if the terminal is in transmission mode TM 9, a Physical Downlink Control Channel "PDCCH" in a subframe reserved for Multicast/Broadcast over a Single Frequency Network "MBSFN". The method comprises decoding a Physical Downlink Shared CHannel "PDSCH" corresponding to the PDCCH in the subframe (530), wherein the subframe is not indicated by higher layers to decode Physical Multicast CHannel "PMCH", and wherein the subframe is not configured by higher layers to be part of a Positioning Reference Signal "PRS" occasion, and the PRS occasion is only configured within MBSFN subframes (525). Cyclic prefix length used in subframe #0 can be normal cyclic prefix.
