Method for sending information, detection method and its device, systems technology field

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

Machine and machine communication（Machine to machine, M2M) it is also referred to as machine type communication（Machine-type Communication, MTC), 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 wireless user device for collecting metrical information and 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..

In Long Term Evolution (Long Term Evolution, LTE) Release 11,3GPP RAN have been had been started up on the enhanced conceptual phases of the RAN of MTC communication（Study Item, SI), and most achievement in research is exported in TR 37. 868 at last.37. 868 mainly have studied the business characteristic i.e. model under different M2M application scenarios and concentrate analyze due to a large amount of MTC UE RACH（Physical Random Access Channel, PRACH) caused by RAN lateral loads it is overweight the problem of.In TR 37. 868, two kinds of MTC UE business model is defined：One kind is that MTC UE reach and are scattered in equally distributed business model, and a kind of is the business model that MTC UE reach into Beta distributions.Second of business model be more applicable a large amount of MTC UE almost simultaneously access network special emergency scene, for example, when powering off, many MTC UE, which are triggered, is linked into this network, and reported data.In addition, 3GPP RAN1 also start the research on inexpensive MTC (low-cost MTC), various reduction cost technologies are analyzed, and summarize into TR36. 888.At the same time, inexpensive MTC UE two kinds of business models are given from RAN1 angles, shown in following Tables 1 and 2.Table 1:The business model feature that inexpensive MTC UE upward cycle is reported

Fig. 1 is the method for sending information flow chart of the embodiment of the present invention 1.As shown in figure 1, in network side, this method includes：

Step 101, to machine type communication user equipment（MTC UE) it is grouped；

In the present embodiment, network side can be grouped according to MTC UE application scenarios or based on geographical position, for example, it is one group that application scenarios identical MTC UE, which are divided, it is one group by UE points similar of MTC of geographical position；But above-mentioned packet mode is not limited to, can be grouped according to actual needs, here is omitted.

Step 102, the schedule information that upstream data transmission or downlink data are received is carried out by the way that every group of MTC UE of signaling dynamic instruction is corresponding；

In the present embodiment, when upstream data is sent, for example, MTC UE, MTC for triggering type

UE is based on network side, and such as transmission one command messages in base station, which report upstream data, gives the base station；Or MTC UE are judged when needing reported data, upstream data is sent to network side.Before upstream data is sent, the MTC UE need to obtain the information of the above-mentioned data transmission of progress of distribution.In addition, when downlink data is received, the MTC UE also need to obtain the information of the progress downlink data reception distributed.The information can give the MTC UE by signaling dynamic instruction. In the present embodiment, the corresponding schedule informations of every group of MTC UE include the corresponding schedule informations of each MTC UE in every group of MTC UE；

For example, the form of the schedule information can be：

In the above-described embodiments, this method may also include：To every group of MTC UE distribution group mark and each MTC UE user label, by this group of identification notification MTC UE, and by each MTC UE label in the MTC UE groups（UE index) notify each MTC UE;

In the present embodiment, identified using group（Group ID) distinguish different MTC UE groups, distributing identical group for same group of MTC UE identifies；For example, group is designated a group Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Group-C- NTI, Group-Cell-Radio Network Temporary Identifier);

In addition, in this case, the CRC that network side can be using group mark to the signaling（Cyclic

Redundancy Check, C C) scrambled, and public search space is mapped to, but can also be scrambled using existing mark, such as use Radio Network Temporary Identifier（RNTI) scrambled, the R TI have many kinds, such as cell NTE (C-R TI), system message RNTI (SI-R TI) and paging RNTI (P-R TI) etc..

In the present embodiment, above-mentioned group of mark and MTC UE label can be passed through the special wireless heterogeneous networks (RRC of user, Radio Resource Control) message or paging (Paging) message informing MTC UE, but above- mentioned information is not limited to, other message informings MTC UE can be also used.

From above-described embodiment, the above-mentioned schedule information of mode dynamic notification based on group can save signaling consumption.In the present embodiment, it is contemplated that one of MTC UE is static the characteristics of important or low speed movement.The MTC UE of many types, are such as used for the MTC UE for monitoring measurement, are in inactive state, i.e. position once starting shooting and determining in the case of placement location, long-time and fix.Utilize this characteristic, this kind of MTC UE to network side, such as base station（ENB channel circumstance) is usually slowly varying, so, can allocate the information such as the resource of uplink/downlink in advance, such as will be used for MTC UE Physical Downlink Shared Channels in advance（Physical Downlink Shared Channel, PDSCH) receive or Physical Uplink Shared Channel（Physical Uplink Shared Channel, PUSCH) used resource allocation is sent to each MTC UE in identical group, for example, resource block used in the up transmission of distribution or downlink reception (Resource Block, RB), the information such as modulation coding mode (Modulation and Code Scheme, MCS).Then using new DCI dynamic dispatchings, each MTC UE carries out upstream data transmission or downlink data reception.Signaling consumption so can be not only reduced, information, the content of simplified signaling of signaling carrying can be also reduced.

Step 203, it is each MTC UE configuration resource informations in every group of MTC UE；

The resource information includes carrying out the partial information in upstream data transmission or the required relevant information of downlink data reception；

And the schedule information is included in the relevant information except the information of the resource information；

In the present embodiment, network side be each MTC UE configurations in every group of MTC UE resource information can identical or part it is identical or entirely different；

Wherein, it can be configured by high-level signaling, for example, when upstream data is sent, can be by public RRC (common RRC) signal deployment to each MTC UE resource informations configured（MTC UE are notified by RRC signaling), so, the resource information of each MTC UE in the MTC UE groups can be with identical；Or by special RRC (dedicated RRC) signal deployment, so, the possible part of resource information of each MTC UE in the MTC UE groups is identical or entirely different；

For example, when downlink data is received, the resource information to each MTC UE distribution in group can use the configuration of common RRC signalings, or using the configuration of dedicated RRC signalings；

But aforesaid way is not limited to, network side can also notify the MTC UE resource informations using other existing any message or newly-built message.

Step 204, the schedule information that upstream data transmission or downlink data are received is carried out by the way that every group of MTC UE of signaling dynamic instruction is corresponding.

In the above-described embodiments, step 201 and 202, can be any with 203,204 orders performed, above are only the embodiment of the present invention. From above-described embodiment, the characteristics of based on MTC UE, the partial information for carrying out upstream data transmission or downlink data reception needs can be pre-configured with, another part information passes through DCI signaling schedulings, signaling consumption is so not only reduced, information, the content of simplified signaling that signaling is carried also is reduced.

In the present embodiment, network side can be also updated to the resource information being pre-configured with, and resource information of renewal is signaled into MTC UE by other.For example, by Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell-Radio Network Temporary Identifier, C-RNTI) scrambling CRC's and user's dedicated search space can be mapped to by existing（UE-Specific Search Space, USS) uplink scheduling DCI information, such as DCI forms 0 indicate.

From above-described embodiment, network side is grouped to MTC UE, and distributes corresponding group mark, is each MTC UE distributing user labels, by group mark and the MTC UE place group user label（UE index) notify MTC UE;The characteristics of based on MTC UE, allocate corresponding resource information in advance, and other information for carrying out up transmission/downlink reception so, can reduce DCI expense by new DCI dynamic instructions, and simplify the field information that DCI is carried, content；From unlike existing DCI, the CRC of the new DCI can be scrambled and be mapped in public search space using group mark；In addition, network side can also update resource information, and it can be indicated by existing DCI.

The embodiment of the present invention 3 provides a kind of method for sending information.

In the present embodiment, illustrated exemplified by sending upstream data for network side dynamic dispatching MTC UE.For example, the MTC UE for triggering type, have two kinds of application scenarios, as described in the background art, here is omitted at present.

For intelligent measure（Smart metering) and be placed on exemplified by the MTC UE of residential building, for example, the MTC UE monitored for fire alarm.It is such to belong to event triggering（Event-triggered type of service), only when occurring emergency, MTC UE need to send upstream data to eNB.Because customer location is fixed, MTC UE group can be divided in units of residential building, the MTC UEs in same residential building are classified as one group.Information similar eNB distribution Group-ID, such as identical Group-C-R TI give the MTC UEs of same residential building, and to each MTC UE distribution label in group（UE-index), corresponding UE-index and group mark are passed through into each MTC UE in RRC signaling group of notifications.

In the present embodiment, when network side dynamic dispatching MTC UE send upstream data, for above-mentioned static or low-speed motion MTC UE, because of its slowly varying channel circumstance, and generally MTC UE upstream traffic very little, therefore, some information can be omitted, and simplify the content of schedule information.

For example, the upstream data amount very little sent due to the MTC UE that dispatch every time, the i.e. data transfer of parcel, With resource block（RB) for unit resource allocation ratio with resource block group（RBG it is) more effective for the resource allocation of unit, do not result in the wasting of resources.The ascending resource distribution type that therefore, it can fix MTC UE is resource allocation type 0.

It is the inexpensive MTC UE with low bandwidth in view of the object that 3GPP RAN1 are being studied at this stage, low bandwidth shows the bandwidth very little supported in this MTC UE, 6 Physical Resource Block (Physical Resource Block of maximum can only such as be supported, PRB) etc., for the MTC UE of this type, frequency domain saltus step（Frequency Hopping) the frequency diversity gain that brings is obvious, therefore, it can consider the transmitting uplink data without frequency domain saltus step.

MTC UE aperiodic channel condition information need not be triggered（CSI) measurement report and aperiodic detection reference signal（SRS) send.

From above-described embodiment, the characteristics of based on MTC UE, above- mentioned information, such as resource allocation type（Resource

Allocation Type), frequency domain saltus step indicate（Frequency Hopping Flag), whether trigger aperiodic channel condition information（CSI) and whether detection reference signal is triggered（SRS information) can be omitted.

Therefore, the These characteristics based on MTC UE, carrying out the relevant information of upstream data transmission may include：The resource block used（RB), modulation coding mode（MCS), cyclic shift（) and orthogonal mask label CS（OCC Index), new data indicates (beautiful）;Wherein, in step 203, network side can allocate a part of information in the relevant information in advance according to actual conditions, for example, the resource block used（RB), modulation coding mode（MCS), cyclic shift（) and orthogonal mask label CS（OCC Index) in one or more.Other information in the relevant information is by DCI dynamic instructions.Citing is illustrated below：

Example 1, such as network side, base station（ENB) allocating the RB resource blocks in group used in each MTC UE transmissions upstream data in advance includes RB original positions and RB number of resources, and MTC UE send PUSCH modulation coding mode（) and corresponding CS/OCC labels MCS.

Based on pre-assigned ascending resource information, in dynamic dispatching, network side, such as base station（ENB the upstream data for) sending multiple MTC UE in a new up DCI format scheduling group is sent.Wherein, in new up DCI forms, following two classes field informations are carried：

1) instruction whether is dispatched（flag) :1 bit；

2) new data is indicated（NDI):1 bit；

The new up DCI format is as follows：

Schedulnfo 1, Schedulnfo 2, Schedulnfo j .., Schedulnfo Ν.

It is embodied as, Flag 1, NDI 1, flag 2, NDI 2, flagj, NDI j, flag N, NDI N.Wherein, Schedulnfoj represents the schedule information that user label is j；J is 1 integer for arriving N, and N is positive integer；Schedulnfo j are indicated comprising 1 bit flag and 1 bit NDI is indicated.

In the present embodiment, the field information entrained by the new up DCI format can be with as shown in table 3 below：The new up DCI format of table 3

Compared with the DCI in existing LTE, when network side dynamic dispatching UE sends upstream data, the field information entrained by new up DCI signalings shown in table 3 is fairly simple, simplifies the content of DCI signalings.In table 3, for same user, the order that above-mentioned scheduling instruction and new data are indicated is any, is not limited to the order shown in table 3.

As an example, table 4 below lists the content of the relevant ascending resource information that DCI format 0 is carried in the prior art, with specific reference to LTE protocol TS36.212.The associate uplink resource allocation field information bit of DCI forms 0 in the existing LTE of table 4（Bit) physical significance

In the above-described embodiments, the network side dynamic dispatching MTC UE situations for sending upstream data are described.The situation of docking receipts downlink data is illustrated below.

The embodiment of the present invention 4 provides a kind of method for sending information.In embodiment 4, for network side dynamic dispatching

MTC UE are illustrated exemplified by receiving downlink data.It is similar to Example 3, similar processing method can also be used when downlink data is received.

By taking the MTC UE business models of order-response modes as an example.Work as network side, such as eNB need to obtain MTC UE groups partially or fully MTC UE upstream data when, the eNB can send one group of MTC UE of command instruction notifications and send upstream data to obtain the information status that respective MTC UE are monitored.Command instructions can be sent in Physical Downlink Shared Channel, i.e. sent on PDSCH, and for one group of MTC UE, content can be identical, also can be different.Now, the downlink data reception that a new DCI format dispatches this group of MTC UE is sent.For example, one group of MTC UE quantity is N, and the information detected at subframe n moment, the eNB by wherein M MTC UE of acquisition, into group, the M MTC UE sends command instructions.
