Description

INFORMATION TRANSMISSION METHOD, DETECTION METHOD AND DEVICE THEREOF

Method for sending information, detection method and its engineering device technique field

The present invention relates to the communications field, more particularly to a kind of method for sending information, detection method and its device.Background technology

Machine and machine communication（The Μ of Machine to machine, Μ 2) machine type communication (Machine-type Communication, MTC) is also referred to as, refer to without the data communication between the machine that manually participate in.For example, the device of machine type（This piece unitedly calls MTC UE) can be for collecting metrical information and wireless user device in certain special time by this information reporting to server（User Equipment , UE).MTC UE can be used for various application scenarios, such as remote sensing monitoring, intelligent measure, and speed tracking etc..

3GPP RAN1 start the research on inexpensive MTC (low-cost MTC), and mainly analyzing 6 kinds reduces the technology of cost, and summarizes into TR36. 888.6 kinds of inexpensive technologies refer to：

1) reduction of maximum bandwidth, represents that the maximum bandwidth that MTC UE are supported is reduced to a relatively low bandwidth, such as 1. 4fflz, 3 Willing z or 5fflz.2) single received antenna；3) peak rate（Peak rate) reduction；4) reduction of transmit power；5) semiduplex mode；6) supported transmission mode（Transmission Modes) reduction.

Wherein, the technology for reducing cost of greatest concern is the reduction of maximum bandwidth, represents the reduction for the maximum bandwidth that MTC UE are supported.For example, if MTC UE are present in the LTE system that system bandwidth is 20 Willing z, conventional user devices can support 20 Willing z system bandwidth, and the maximum bandwidth that MTC UE are supported is compared to bandwidth lower for 20 Willing z, e.g. 1. 4fflz, 3 Willing z or 5fflz.

The MTC UE for supporting low bandwidth a kind of at present method is exactly it is coexisted in existing LTE system.MTC UE coexist in LTE system, it is meant that possess and support the MTC UE of low bandwidth ability to need the normal work in the LTE system of big bandwidth, and this needs the support standardized.One of them main problem is that：Possess and support the MTC UE of low bandwidth ability can not demodulate traditional Physical Downlink Control Channel sent in whole system bandwidth（Physical Downl ink Control Channel, PDCCH).

Fig. 1 is the LTE system schematic diagram that MTC UE coexist in 20 Willing z.As shown in figure 1, the maximum bandwidth of MTC UE work is 6, LTE system center Physical Resource Block（Physical Resource Blocks, PRBs), i.e. 1. 4MHz.Traditional PDCCH takes wide 3 OFDM before a frame（Orthogonal Frequency Division Multiplexing, OFDM) symbol is to take whole system bandwidth on frequency domain.MTC UE are due to limited bandwidth of operation, it is impossible to demodulate PDCCH.

Further, since the maximum bandwidth of operation of reduction, MTC UE can only in the bandwidth of restriction transceiving data, for the angle of supported MTC UE quantity, the reduction of maximum bandwidth also defines supported MTC UE capacity.But if to supporting the different MTC UE of low bandwidth ability to configure different frequency domain positions, very big influence will not be caused to MTC UE capacity to a certain extent.

Fig. 2 is the schematic diagram for the low bandwidth that different MTC UE have different frequency domain position configurations.As shown in Fig. 2 the maximum bandwidth that MTC UEK UE2, UE3 and UE4 are supported is 1. 4MHz, but MTC UE1 are identical with the low bandwidth frequency domain position that UE2 works, and the frequency domain position of MTC UE3 and UE4 low bandwidth is in other region.

Fig. 1 and Fig. 2 are that the MTC UE of low bandwidth and common user are coexisted in the LTE system of big bandwidth, difference is in Fig. 1 that all MTC UE are operated in the frequency domain position difference of its low bandwidth supported of difference MTC UE in identical low bandwidth, Fig. 2 to support more MTC UE.Because traditional PDCCH is sent in whole system bandwidth all the time, no matter the PDCCH is to be mapped to public search space（Common Search Space, CSS) still it is mapped to user's dedicated search space（UE-specific Search Space, USS), the low bandwidth MTC UE of above two type can not demodulate this traditional PDCCH.

The content that traditional PDCCH is carried is referred to as Downlink Control Information（Downlink Control Information, DCI), the DCI can carry special schedule information to some specific user equipment, can also carry public schedule information or public information to all user equipmenies in certain user's equipment or cell.

For carrying public schedule information to all user equipmenies in certain user's equipment or cell with the DCI of resource location where indicating public information, for example, dispatch System information block（System Information Blocks, SIBs)/paging（Paging the) (Message2 of message/message 2, msg2 DCI), the DCI is by corresponding system message Radio Network Temporary Identifier (System Information RNTI, SI-RNTI)/Paging messaging wireless network temporary marks（Paging RNTI, P-RNTI)/random access radio network temporary mark（Random Access RNTI, RA-RNTI) scrambling, and it is mapped to public search space i.e. CSS;For directly carrying public information such as transmit power control instruction (Transmit Power Control Command, TPC command) give certain user's equipment DCI, the Downlink Control Information directly carries TPC command, and this DCI controls Radio Network Temporary Identifier by corresponding transmit power（Transmit Power Control RNTI, TPC-RNTI) scrambling, and it is mapped to public search space.

DCI for being mapped to CSS, current solution to the problems described above is exactly by schedule information and corresponding PDSCH Information replicates transmission in the low bandwidth that each MTC UE is supported.Now, the frequency domain position region of each low bandwidth has a DCI (to be carried by PDCCH carryings or ePDCCH）To dispatch public information, what the frequency domain position of each low bandwidth was sent is the copy of public information.

Inventor has found during the present invention is realized, when schedule information and corresponding PDSCH information to be replicated to transmission in the low bandwidth that each MTC UE is supported, can consume substantial amounts of control signaling expense to dispatch public information;Simultaneously because the frequency domain position of each low bandwidth needs to send the copy of public information, it can also consume substantial amounts of PDSCH resources to transmit identical information, so as to cause insufficient resource utilization and limited performance.There is presently no the method for effectively obtaining above-mentioned schedule information and PDSCH information.

It should be noted that the introduction to technical background is intended merely to the convenient explanation clear, complete to technical scheme progress above, and facilitates the understanding of those skilled in the art and illustrate.Can not be merely because these schemes be set forth in the background section of the present invention and think that above-mentioned technical proposal is known to those skilled in the art.The content of the invention
