Description

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

Technical field

The present invention relates to the communications fields, and in particular to a kind of publicly-owned message method, device, publicly-owned message is connect Receiving method, device and publicly-owned message delivery system.

Background technique

Machine type communication (Machine Type Communication, referred to as MTC) user equipment (User Equipment, referred to as UE, also known as user terminal), also known as 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 it is high, more and more mobile operator select LTE/LTE-A as broadband wireless communications The evolution tendency of system.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, i.e., each subframe can be with Different control channels is transmitted, frame structure is as depicted in figs. 1 and 2.

Fig. 1 is frequency division duplex (Frequency Division Duplexing, referred to as FDD) mould according to the relevant technologies The schematic diagram of the frame structure of formula, as shown in Figure 1, the radio frames of a 10ms are 0.5ms by 20 length, number 0~19 Time slot (slot) composition, time slot 2i and 2i+1 form subframe (subframe) i that length is 1ms, and i is 0 or natural number.

Fig. 2 is time division duplex (Time Division Duplexing, referred to as TDD) mode according to the relevant technologies The schematic diagram of frame structure, as shown in Fig. 2, the radio frames of a 10ms are made of the field (half frame) of two a length of 5ms, One field includes the subframe that 5 length are 1ms, and subframe i is defined as the time slot 2i and 2i+1 of 2 a length of 0.5ms.

Defined in LTE/LTE-A Physical Downlink Control Channel (Physical Downlink Control Channel, Referred to as PDCCH).Wherein, Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, referred to as PCFICH) carrying information be used to indicate in a subframe transmit PDCCH orthogonal frequency division multiplexing The number of (Orthogonal Frequency Division Multiplexing, referred to as OFDM) symbol.Physical mixed ARQ Instruction channel (Physical Hybrid-ARQ Indicator Channel, referred to as PHICH) is for carrying uplink number According to acknowledgement/non-acknowledgement (ACK/NACK) feedback information, wherein ARQ be automatic repeat request (Automatic Repeat-reQuest abbreviation).

PDCCH is for bearing downlink control information (Downlink Control Information, referred to as DCI), packet It includes: uplink and downlink scheduling information and uplink power control information.

Usual MTC terminal can obtain DCI by demodulating PDCCH channel in each subframe, to realize to physical down Shared channel (Physical Downlink Share Channel, referred to as PDSCH) and Physical Uplink Shared Channel The demodulation of (Physical Uplink Share Channel, referred to as PUSCH).

The message carried on PDSCH is divided into publicly-owned message and the proprietary message of user, is usually one small for publicly-owned message Multiple UE can be received simultaneously in area, and the proprietary message of user is typically only capable to be that a UE is received in a cell.And And no matter PDSCH carrying be publicly-owned message or user's specific messages, require PDCCH and be scheduled instruction, i.e., terminal must It must first be properly received after PDCCH, PDSCH can be received.

The present inventor has found in the course of the research, in practical applications, have a Terminal Type due to present position or Self-characteristic is limited to be remarkably decreased so as to cause covering performance.For example, smart meter reading class MTC terminal is fixedly mounted on underground mostly Under the low covering performance environment such as room, mainly send away a parcel data, and the requirement to data rate is low, can tolerate biggish data Propagation delay time.Since such terminal log is low according to rate requirement, for data channel, lower modulating-coding can be passed through The modes such as transmission are repeated several times to guarantee the correct transmission of small bag data in rate and time domain, synchronizing channel itself is sent out What is sent is exactly identical information, the identical information that terminal is sent by receiving multiple subframes.Therefore the field limited in covering Under scape, Traffic Channel and control channel require to repeat to transmit to promote covering.For carrying the Traffic Channel weight of publicly-owned message Multiple transmission needs the control channel in publicly-owned search space to repeat to dispatch instruction, and publicly-owned search space is smaller at present, right It will lead to blocking rate in a large amount of repetition transmission to greatly promote, so that system can not work.Therefore, it is necessary to provide one kind The method of publicly-owned message how is transmitted under the scene of coverage enhancement.
