Publicly-owned message sending, receiving method, Apparatus and system

Technical field

The present invention relates to the communications field, in particular to the publicly-owned message method of one, device, publicly-owned message receival method, device and publicly-owned message delivery system.

Background technology

Machine type communication (Machine Type Communication, referred to as MTC) subscriber equipment (User Equipment, referred to as UE, be also called user terminal), be also called machine to machine (Machine to Machine, referred to as M2M) user communication device is the main application form of current Internet of Things.In recent years, due to Long Term Evolution (Long-Term Evolution, referred to as LTE)/advanced long-term evolution system (Long-Term Evolution Advance, referred to as LTE-Advance or LTE-A) spectrum efficiency high, increasing mobile operator selects LTE/LTE-A as the evolution tendency of system of broadband wireless communication.MTC multiple types data service based on LTE/LTE-A also will be more attractive.

Existing LTE/LTE-A system is transmitted based on each subframe dynamic dispatching, and namely each subframe all can transmit different control channels, and its frame structure as depicted in figs. 1 and 2.

Fig. 1 is Frequency Division Duplexing (FDD) (the Frequency Division Duplexing according to correlation technique, referred to as FDD) schematic diagram of the frame structure of pattern, as shown in Figure 1, the radio frames of a 10ms is 0.5ms by 20 length, time slot (slot) composition of numbering 0 ~ 19, time slot 2i and 2i+1 forms length, and to be subframe (subframe) i, the i of 1ms be 0 or natural number.

Fig. 2 is time division duplex (the Time Division Duplexing according to correlation technique, referred to as TDD) schematic diagram of the frame structure of pattern, as shown in Figure 2, the radio frames of a 10ms is made up of two long fields (half frame) for 5ms, it is the subframe of 1ms that a field comprises 5 length, and subframe i is defined as 2 long time slot 2i and 2i+1 for 0.5ms.

Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) is defined in LTE/LTE-A.Wherein, Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, referred to as PCFICH) information that carries is used to indicate the number of OFDM (OrthogonalFrequency Division Multiplexing, referred to as the OFDM) symbol transmitting PDCCH in a subframe.Physical mixed ARQ indicating channel (PhysicalHybrid-ARQ Indicator Channel, referred to as PHICH) for carrying acknowledgement/non-acknowledgement (ACK/NACK) feedback information of uplink transmission data, wherein, ARQ is the abbreviation of HARQ (Automatic Repeat-reQuest).
