Abstract: A method is provided for a UE to determine the start time of the downlink control channel for M2M communication in LTE systems. The method comprises a UE receiving a parameter set to determine the start time of the (E)PDCCH from the eNB; calculating the start time based on the received parameter set from the eNB; combining/decoding the repetitive (E)PDCCHs; and sending the feedback information to confirm/reject the reception of the (E)PDCCH.

Abstract: The invention provides a method of pattern-based message transmission. The method can predetermine a transmission pattern for the message transmission between a base station and a user equipment according to a service type, an equipment identifier, and etc., of the equipment and can hereby determine a transmission process of signaling and data and thus can handle the remaining transmission of either signaling or data to be performed in the predetermined pattern, which means that scheduling resources can be greatly saved and thus signaling overheads and the resource consumption can be greatly reduced. With an optimized design of a pattern, an acknowledgement message and subsequent signalings and/or data could be encapsulated in a same data packet for transmission and reception, thereby resources are further saved. This improves the efficiency of utilizing signaling greatly in general, reduces signaling overheads, and also facilitates various communication between other users in the cell, improves the efficiency of economy and saves cost.
