Description

 Information transmitting method, detecting method and device thereof, system

 The present invention relates to the field of communications, and in particular, to an information sending method, a detecting method, an apparatus, and a system thereof. Background technique

 Machine to machine (M2M) is also called Machine-type Communication (MTC), which refers to data communication between machines without human intervention. For example, a device of the machine type (referred to as MTC UE in this section) may be a wireless user device (User Equipment, UE) for collecting measurement information and reporting this information to the server at a specific time. The MTC UE can be used in various application scenarios such as remote sensing monitoring, intelligent measurement, and speed tracking.

 In Long Term Evolution (LTE) Release 11, the 3GPP RAN has initiated a RAN-enhanced research phase (Study Item, SI) on MTC communication, and finally outputs the research results in TR 37.868. 37. 868 mainly studied the service characteristics of different M2M application scenarios, namely the model, and analyzed the problem of excessive load on the RAN side due to the random access channel (PRACH) of a large number of MTC UEs. In TR 37. 868, two MTC UE service models are defined: one is that the MTC UEs are distributed to a uniformly distributed service model, and the other is that the MTC UEs reach a beta-distributed service model. The second service model is more suitable for a special emergency scenario where a large number of MTC UEs access the network at the same time. For example, when a power outage occurs, many MTC UEs are triggered to access the network and report data. In addition, 3GPP RAN1 also initiated research on low-cost MTC (low-cost MTC), analyzed various low-cost technologies, and summarized it in TR36.888. At the same time, two business models of low-cost MTC UEs are given from the perspective of RAN1, as shown in Table 1 and Table 2 below.

基于上述内容， MTC UE 一般是周期性或者触发性质的发送上行信号。 对于触发 类型的 MTC UE, 目前有两种应用场景。

Based on the above, the MTC UE generally transmits the uplink signal in a periodic or triggering nature. For the trigger type MTC UE, there are currently two application scenarios.

 One application scenario is the report of the command-response mode. For example, for the MTC UE used for remote sensing monitoring, the network side, for example, the base station may send a command message to the MTC UE in order to obtain data monitored by the MTC UE; after receiving the command message from the base station, the MTC UE passes the uplink. The channel reports the monitored data to the base station.

 Another application scenario is an event-triggered type of MTC UE. For example, the MTC UE for detecting the water level sends an alarm message to the network side, such as the base station, once the detected water level exceeds a predefined threshold. Before uplink transmission, the MTC UE must obtain the allocated uplink resources to be able to send uplink signals on the allocated uplink resources. The uplink resource is allocated by the base station to the MTC UE. For this type of MTC UE, since the base station does not know the time when the uplink service arrives, dynamic scheduling is required. When multiple MTC UEs are triggered to send uplink data, the downlink control channel overhead needs to be consumed for uplink scheduling to allocate resources. In addition, based on the existing 3GPP research on MTC, an important feature of MTC is that there are a large number of MTC UEs in existing wireless systems. Due to the existence of a large number of MTC UEs, once many MTC UEs are triggered to transmit signals, a large amount of downlink control signaling overhead is consumed for resource allocation of these MTC UEs.

Currently, there is no effective way to save a lot of signaling overhead. It should be noted that the above description of the technical background is only for the purpose of facilitating the clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art.

 Various embodiments of the present invention will be described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not limiting of the invention.

 The embodiment provides an information sending method, which classifies device type user equipments (MTC UEs), and uses dynamic signaling to indicate scheduling information of uplink data transmission or downlink data reception corresponding to each group of MTC UEs. Since the MTC UE is scheduled based on the group, signaling overhead can be saved. In addition, related resource information can be pre-configured so that the content of the scheduling information can be simplified.

 The information transmitting method and detecting method according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a flow chart showing a method of transmitting information according to a first embodiment of the present invention. As shown in Figure 1, on the network side, the method includes:

 Step 101: Group machine type communication user equipments (MTC UEs);

 In this embodiment, the network side may perform grouping according to the application scenario of the MTC UE or the geographic location, for example, grouping the MTC UEs with the same application scenario into one group, and grouping the MTC UEs with similar geographical locations into one group; It is not limited to the above grouping method, and may be grouped according to actual needs, and details are not described herein again.

 Step 102: Dynamically indicate, by using signaling, scheduling information corresponding to each group of MTC UEs for performing uplink data transmission or downlink data reception.

 In this embodiment, for the case of uplink data transmission, for example, for the trigger type MTC UE, MTC

The UE is based on the network side, for example, the base station sends a command message to report the uplink data to the base station; or when the MTC UE determines that the data needs to be reported, the uplink data is sent to the network side. Before transmitting the uplink data, the MTC UE needs to obtain the allocated information for performing the above data transmission. In addition, for the case of downlink data reception, the MTC UE also needs to obtain the allocated information for downlink data reception. This information can be dynamically indicated to the MTC UE by signaling. In this embodiment, the scheduling information corresponding to each group of MTC UEs includes scheduling information corresponding to each MTC UE in each group of MTC UEs;

 For example, the format of the scheduling information can be:

 Schedulnfo 1 , Schedulnfo 2 , , Schedulnfo j, , Schedulnfo N

 The Schedulnfo j' indicates that the user equipment label in the scheduling group is the scheduling information of the UE_index=j. In this embodiment, the signaling may be a downlink control indicator (DSI), and is performed on multiple MTC UEs. The scheduling of uplink transmission or downlink reception is different from the existing DCI format, and the DCI can be transmitted on a physical downlink control channel (PDCCH) or an enhanced PDCCH.

 In the above embodiment, the method may further include: assigning a group identifier and a user label of each MTC UE to each group of MTC UEs, notifying the MTC UE of the group identifier, and labeling each MTC UE in the MTC UE group. (UE index) notifying each MTC UE;

 In this embodiment, a group ID is used to distinguish different MTC UE groups, and the same group identifier is assigned to the same group of MTC UEs; for example, the group identifier is a group cell radio network temporary identifier (Group-C-NTI) , Group-Cell-Radio Network Temporary Identifier) ;

 In addition, in this case, the network side can use the group identity to verify the cyclic redundancy of the signaling (Cyclic

Redundancy Check (CC) performs scrambling and maps to the common search space, but can also be scrambled with existing identifiers. For example, using the Radio Network Temporary Identity (RNTI) for scrambling, there are many types of R TI, such as cell NTE. (CR TI), system message RNTI (SI-R TI) and paging RNTI (PR TI).

 In this embodiment, the group identifier and the label of the MTC UE may be notified to the MTC UE by using a user-specific RRC (Radio Resource Control) message or a paging (Paging) message, but the information is not limited to the foregoing information. The MTC UE is notified by other messages.

It can be seen from the above embodiment that the scheduling information is dynamically notified in a group-based manner, which can save signaling overhead. In this embodiment, it is considered that an important feature of the MTC UE is stationary or low speed movement. Many types of MTC UEs, such as the MTC UEs used for monitoring measurements, once turned on and determine the placement position, are in a static state for a long time, that is, the position is fixed. With this feature, the channel environment of the MTC UE to the network side, such as the base station (eNB), is generally changed slowly, so that information such as uplink/downlink resources can be allocated in advance, such as the physical downlink shared channel used for the MTC UE in advance ( Physical Downlink Shared Channel, PDSCH) The resources used for the physical uplink shared channel (PUSCH) transmission are allocated to each MTC UE in the same group, for example, the resource block used for uplink transmission or downlink reception is allocated. (Resource Block, RB), Modulation and Code Scheme (MCS) and other information. Then, the new DCI is used to dynamically schedule each MTC UE for uplink data transmission or downlink data reception. This not only reduces the signaling overhead, but also reduces the information carried by the signaling and simplifies the content of the signaling.

 The above embodiments will be described below with reference to the accompanying drawings.

 Fig. 2 is a flow chart showing the method of transmitting information according to the second embodiment of the present invention. As shown in Figure 2, on the network side, the method includes:

 Step 201: Group machine type communication user equipments (MTC UEs);

 Step 202: Assign a group identifier to each group of MTC UEs, notify the MTC UE of the group identifier, and assign a user label to each MTC UE in each group, and notify each user label of each MTC UE in each group of MTC UEs MTC UEs;

 Step 203: Configure resource information for each MTC UE in each group of MTC UEs.

 The resource information includes part of information related to performing uplink data transmission or downlink data reception;

 And the scheduling information includes information of the related information except the resource information;

 In this embodiment, the resource information configured by the network side for each MTC UE in each group of MTC UEs may be completely the same, or partially the same, or completely different;

 The resource information configured for each MTC UE may be configured by common RRC signaling (ie, the MTC UE is notified by RRC signaling), for example, in the case of uplink data transmission. The resource information of each MTC UE in the MTC UE group may be identical; or configured by dedicated RRC signaling, so that the resource information of each MTC UE in the MTC UE group may be partially the same or completely Different

 For example, for the case of downlink data reception, the resource information allocated to each MTC UE in the group may be configured by common RRC signaling, or configured by dedicated RRC signaling;

 However, the network side may also use any other existing message or newly created message to notify the MTC UE of the resource information.

 Step 204: Dynamically indicate, by using signaling, scheduling information corresponding to each group of MTC UEs for performing uplink data transmission or downlink data reception.

In the above embodiment, the order of steps 201 and 202, and 203, 204 may be arbitrary, and the above is only the embodiment of the present invention. It can be seen that, according to the characteristics of the MTC UE, part of the information required for uplink data transmission or downlink data reception may be pre-configured, and another part of information is scheduled by DCI signaling, thereby reducing signaling overhead and reducing signaling carrying. The information, simplifying the content of the signaling.

 In this embodiment, the network side may also update the pre-configured resource information, and notify the MTC UE of the updated resource information by other signaling. For example, the uplink scheduling DCI can be scrambled by the existing Cell-Radio Network Temporary Identifier (C-RNTI) and mapped to the UE-Specific Search Space (USS). Information, as indicated by DCI format 0.

 As shown in the foregoing embodiment, the network side groups the MTC UEs, allocates corresponding group identifiers, assigns a user label to each MTC UE, and notifies the MTC UE of the group identifier and the user index (UE index) of the group in the group. According to the characteristics of the MTC UE, the corresponding resource information is pre-allocated, and other information for performing uplink/downlink reception is dynamically indicated by the new DCI, so that the DCI overhead can be reduced, and the field information and content carried by the DCI are simplified; Different from the existing DCI, the CRC of the new DCI can be scrambled and mapped into the common search space by using the group identifier; in addition, the network side can also update the resource information and can be indicated by the existing DCI.

 Embodiment 3 of the present invention provides a method for transmitting information.

 In this embodiment, an example is described in which the network side dynamically scheduling the MTC UE to send uplink data. For example, for the MTC UE of the trigger type, there are currently two application scenarios, as described in the background art, and details are not described herein again.

 For example, an MTC UE for smart metering and placed in a residential building, for example, an MTC UE for fire alarm monitoring. This type of event-triggered service type requires the MTC UE to send uplink data to the eNB only in the event of an emergency. Because the user's location is fixed, the MTC UE group can be divided into residential units, and the MTC UEs in the same residential building are grouped together. The eNB allocates information similar to the Group-ID, such as the same Group-CR TI to the MTC UEs of the same residential building, and assigns a label (UE-index) to each MTC UE in the group, and passes the corresponding UE-index and group identifier through the RRC. Signaling each MTC UE within the group.

 In this embodiment, when the network side dynamically schedules the MTC UE to send uplink data, for the above-mentioned static or low-speed motion MTC UE, due to its slowly changing channel environment, and generally, the uplink traffic of the MTC UE is small. Therefore, some information can be omitted to simplify the content of the scheduling information.

For example, since the amount of uplink data sent by each scheduled MTC UE is small, that is, data transmission of the packet, Resource allocation in resource block (RB) units is more efficient than resource allocation in resource block group (RBG) units, and does not waste resources. Therefore, the uplink resource allocation type of the fixed MTC UE is the resource allocation type 0.

 Considering that the current 3GPP RAN1 is researching a low-cost MTC UE with low bandwidth, the low bandwidth performance of this MTC UE supports a small bandwidth, such as only supporting up to 6 physical resource blocks (Physical Resource Block, PRB), etc. For this type of MTC UE, the frequency domain diversity gain caused by frequency hopping is not obvious. Therefore, uplink data transmission without frequency domain hopping can be considered.

 There is no need to trigger the aperiodic channel state information (CSI) measurement report and the aperiodic sounding reference signal (SRS) transmission of the MTC UE.

 According to the foregoing embodiment, based on the characteristics of the MTC UE, the foregoing information, such as a resource allocation type (Resource)

Allocation Type), Frequency Hopping Flag, whether to trigger aperiodic channel state information (CSI) and whether to trigger the sounding reference signal (SRS) can be omitted.

 Therefore, based on the foregoing features of the MTC UE, the related information for performing uplink data transmission may include: a resource block (RB), a modulation and coding scheme (MCS), a cyclic shift (CS), and an orthogonal mask label (OCC Index) used. The new data indicates (Li); wherein, in step 203, the network side may pre-allocate a part of the related information according to an actual situation, for example, a used resource block (RB), a modulation and coding scheme (MCS), and a cyclic shift. One or more of bit (CS) and orthogonal mask number (OCC Index). The other information in this related information is dynamically indicated by the DCI. The following examples are given:

 Example 1, the network side, as the base station (eNB) pre-allocates the RB resource blocks used by each MTC UE in the group to transmit uplink data, including the RB start position and the RB resource number, and the MTC UE transmits the modulation coding mode (MCS) of the PUSCH and corresponding CS/OCC label.

 Based on the pre-allocated uplink resource information, the network side, such as a base station (eNB), transmits uplink data transmissions of multiple MTC UEs in a new uplink DCI format scheduling group. Among them, the new uplink DCI format carries the following two types of field information:

 1) Whether to schedule the flag (flag): 1 bit;

 2) New Data Indication (NDI): 1 bit;

 The new upstream DCI format is as follows:

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

Specifically expressed as Flag 1 , NDI 1 , flag 2, NDI 2, , flagj, NDI j, , flag N, NDI N. Wherein, Schedulnfoj represents scheduling information of the user label j; j is an integer from 1 to N, and N is a positive integer; Schedulnfo j includes a 1-bit flag indication and a 1-bit NDI indication.

 In this embodiment, the field information carried in the new uplink DCI format can be as shown in Table 3 below: Table 3 New uplink DCI format

与现有 LTE中的 DCI相比， 网络侧动态调度 UE发送上行数据时， 表 3所示的 新的上行 DCI信令所携带的字段信息比较简单， 简化了 DCI信令的内容。在表 3中， 对于同一个用户， 上述调度指示和新数据指示的顺序任意， 不限于表 3所示的顺序。

Compared with the DCI in the existing LTE, when the network side dynamically schedules the UE to send the uplink data, the field information carried by the new uplink DCI signaling shown in Table 3 is relatively simple, and the content of the DCI signaling is simplified. In Table 3, for the same user, the order of the above-mentioned scheduling indication and new data indication is arbitrary, and is not limited to the order shown in Table 3.

 As an example, Table 4 below lists the contents of the uplink resource information carried by the DCI format 0 in the prior art, with specific reference to the LTE protocol TS36.212.

The resource allocation type 0 indicates a set of consecutive resource blocks allocated to the scheduled UE. This type of resource allocation allocates resources in units of RBs, and combines resource block assignment and hopping resource allocation. The start position of the contiguous resource block allocated to the scheduled UE and the number of allocated RBs can be known; the resource allocation type 1 represents two sets of resource blocks allocated to the scheduled UE, and each set of resource blocks includes one or more consecutive resources. Resource Block Group (BG), this type of resource allocation allocates resources in units of RBGs, and the RBG resources allocated to the scheduled UEs can be obtained by combining the field resource block allocations.

 As shown in Table 3, similar to DCB/3A, the load size of the new DCI format is equal to the load of DCI format 0, and the field information of the new DCI format scheduling for each MTC UE occupies 2 bits, so format 0

Based on the pre-allocated uplink resource information, during dynamic scheduling, the network side, such as a base station (eNB), transmits uplink data transmissions of multiple MTC UEs in a new DCI format scheduling group. Among them, the new uplink DCI format carries the following three types of field information:

 1) Whether to schedule the flag (flag): 1 bit;

 2) New Data Indication (NDI): 1 bit;

In Table 5, the order of the above-mentioned scheduling indication, new data indication, cyclic shift, and orthogonal mask label is arbitrary for the same user, and is not limited to the order shown in Table 5.

The MTC UE receives downlink data as an example for description. Similar to Embodiment 3, a similar processing method can be employed for the case of downlink data reception.

 Take the MTC UE service model in command-response mode as an example. When the network side, for example, the eNB needs to obtain uplink data of some or all MTC UEs in the MTC UE group, the eNB may send a command command to notify a group of MTC UEs to send uplink data to obtain information status monitored by the respective MTC UE. The command command can be sent on the physical downlink shared channel, that is, on the PDSCH, and the content may be the same or different for a group of MTC UEs. At this time, a new DCI format is sent to schedule downlink data reception of the group of MTC UEs. For example, the number of MTC UEs is N. In the subframe n, the eNB sends a command command to the M MTC UEs in the group to obtain information detected by the M MTC UEs.

Similar to Embodiment 3, for a fixed-position MTC UE, due to its slowly changing channel environment, In general, the downlink traffic of the MTC UE is smaller than the uplink traffic. Therefore, some information can be omitted, simplifying the content of the scheduling information.

 For example, since the amount of downlink data received by each scheduled MTC UE is small, that is, data transmission of packets, resource allocation in units of resource blocks (RBs) is more effective than resource allocation in units of resource block groups (RBGs). , will not cause waste of resources. Therefore, the downlink resource allocation type of the fixed MTC UE is resource allocation type 1. Thus, the Resource Allocation Type can be omitted.

 In this embodiment, the related information for performing downlink data reception according to the characteristics of the MTC UE includes: a used resource block (RB), a modulation and coding scheme (MCS), and a hybrid adaptive repeat request (HARQ). Process label, new data indicator surface), redundancy version (RV).

 In this embodiment, similar to the embodiment 3, in step 203, the network side may pre-allocate a part of the related information, that is, resource information, for example, the used resource block (RB), modulation and coding mode, according to actual conditions. (MCS). Other information in this related information is dynamically indicated by the DCI. The following examples are given.

 For example, when the downlink data sent by the network side to each MTC UE in the group is different, the dedicated RRC information may be used to configure the resource information. In dynamic scheduling, the network side, such as the base station (eNB), sends a new downlink DCI format scheduling. Downlink data reception of multiple MTC UEs in the group. The new downlink DCI format schedules multiple PDSCH transmissions, and the MTC UE may receive the new downlink DCI format scheduling to the PDSCH of the MTC UE at a pre-allocated resource location.

 For example, when the resource information includes the RB and the MCS, the new downlink DCI format carries the following field information: 1) whether a scheduling indication (flag): 1 bit;

 2) New data indication: 1 bit;

 3) Hybrid Automatic Repeat Request (HARQ) process label:

 3 bits (FDD), 4 bits (TDD);

 4) Redundancy version: 2 bits;

 Similar to Embodiment 3, the new downlink DCI format is as follows:

 Flag 1 , NDl 1 , HARQ process number 1 , RV 1 , flag 2, NDl 2, HARQ process number 2, RV 2, .. ·, flagj, NDl j , HARQ process number j, RVj, .. ·, flag N , NDl N, HARQ process number N, RV N.

 For the above symbols, the contents of Embodiment 3 and Embodiment 4 can be referred to.

Thus, as shown in Table 7, the field information "TPC command" is also included, occupying 2 bits, and the new DCI format scheduling is performed at this time.

It can also be indicated by other signaling dynamic indications, such as the existing DCI format 3/3A.

The load situation in the TDD system is similar to the load situation in the FDD system, and is not described here. Example 2: On the network side, if the downlink data sent by the eNB to each MTC UE in the group is the same, The resource information is configured by common RRC signaling. Based on the pre-allocated downlink resource information, the network side, such as a base station (eNB), transmits downlink data reception of multiple MTC UEs in a new downlink DCI format scheduling group. The new downlink DCI format schedules one PDSCH transmission, and the multiple MTC UEs receive the PDSCH scheduled by the new downlink DCI format at the same resource location.

The load size of the new downlink DCI format shown in Table 8 is equal to the load of DCI format 1, and the new DCI format schedules user-specific field information for each MTC UE to occupy 1 bit, which is scheduled to be common to each MTC UE. The field information (NDI, HARQ process label, redundancy version) occupies 6 bits (under the FDD system), and the user-specific field information scheduled for each MTC UE occupies 1 bit, so = ^^^-6. That is, the number of MTC UEs that can receive the downlink data that can be scheduled at one time in the DCI format is at most N = _f . _{Mat l} -6, where. _{Mat l} represents the load size before the Cyclic Redundancy Check (CC) check when the DCI format 1 is mapped to the UE-specific Search Space (USS).

In this embodiment, the related information may further include a closed loop power control instruction (TPC command) when the MTC UE scheduled to receive the downlink data sends the PUCCH, where the closed loop control instruction may be included in the scheduling information. Dynamic indication via this new DCI. In this way, as shown in Table 8, the field information "TPC command" is also included, which occupies 2 bits. At this time, the new DCI format schedules user-specific field information for each MTC UE to occupy 3 bits, and is scheduled for each MTC UE. Common field information occupies 6 bits (under FDD system), so W format]

 In addition, the closed loop control command can also be dynamically indicated by other signaling, such as the existing DCI format 3/3A. In summary, for the downlink data reception, the network side may determine the MTC included in each group of MTC UEs according to the load size of the new downlink DCI signaling and the field information carried by the signaling.

 The two methods of receiving downlink data by multiple MTC UEs in the group mode scheduling group in the above example may be applied to the MTC UE of the command-response service model. Similar to the uplink DCI designed in the embodiment in which the uplink data is sent by multiple MTC UEs in the group-based scheduling group, the new downlink DCI signaling designed in the above example may be different according to the load size and the combination of the carried field information. The number of MTC UEs in one MTC Group when the eNB is grouping the MTC UEs may be determined.

 Compared with the downlink DCI in the existing LTE, when the network side dynamically schedules the UE to receive the downlink data, the field information carried by the new uplink DCI signaling shown in Table 7 and Table 8 is relatively simple, and the content of the DCI signaling is simplified. . In Table 7, for the same user, the order of the above-mentioned scheduling indication and new data indication is arbitrary, and is not limited to the order shown in Table 7. In Table 8, the field information is not limited to the order of Table 8.

 As an example, Table 10 below lists the contents of the uplink resource information carried by the DCI format 1 of the Scheduling Single Codeword PDSCH transmission in the prior art, with specific reference to the LTE protocol TS36.212. Take DCI format 1 as an example. Table 10 Existing DCI format 1

 Physical uplink control channel 2 bits Fast closed loop power control adjusts the user's (PUCCH) power control command PUCCH transmission power In Table 10, the downlink resource allocation type is divided into resource allocation type 0, resource allocation type 1 and resource allocation type 2. The resource allocation type 1 can achieve the resource allocation in units of RBs. For an MTC UE with a small downlink traffic, the fixed downlink resource allocation type can be 1.

 It can be seen from the foregoing embodiments 2, 3, and 4 that the network side pre-allocates corresponding resource information based on the characteristics of the MTC UE, and other information for performing uplink transmission/downlink reception is dynamically indicated by the new DCI, thereby reducing DCI. The overhead, and simplifying the field information and content carried by the DCI; unlike the existing DCI, the CRC of the new DCI can be scrambled and mapped into the common search space by using the group identifier;

 In addition, the network side can also update the resource information and can be indicated by the existing DCI.

 More broadly, when there is only one MTC UE in a group, the above method still applies. Fig. 3 is a flow chart showing the detecting method of the embodiment 5 of the present invention. As shown in FIG. 3, on the UE side, the method includes: Step 301: The MTC UE detects, by the network side, the scheduling information of the MTC UE group to which the MTC UE belongs, which is dynamically indicated by the network, where the scheduling information of the MTC UE group includes the Scheduling information for uplink data transmission or downlink data reception corresponding to each MTC UE in the group;

 Step 302: Obtain scheduling information corresponding to the MTC UE according to the user identifier of the MTC UE.

 It can be seen from the foregoing embodiment that the MTC UE can obtain corresponding scheduling information by detecting the signaling.

 In this embodiment, on the network side, if the signaling is mapped to the common search space, on the UE side, in step 301, the MTC UE detects the scheduling information of the MTC UE group in the common search space.

 In addition, on the network side, if the CRC of the DCI signaling is scrambled by using the group identifier, on the UE side, in the process of detecting in step 301, the signaling is descrambled by using the group identifier to obtain the group. Scheduling information.

 And the scheduling information includes information of the related information other than the resource information.

 In this embodiment, the method further includes: the MTC UE transmitting uplink data or receiving downlink data according to the scheduling information corresponding to the MTC UE and the received resource information.

 In this embodiment, when the related information includes the closed loop power control instruction, if the network side includes the closed loop power control instruction in the scheduling information, the scheduling information detected by the MTC UE further includes a closed loop power control instruction;

 If the network side uses the existing DCI, such as DCI format 0 to indicate a closed loop power control command, the MTC UE will detect in the user-specific search space to obtain the closed loop power control instruction, which is similar to the prior art. I won't go into details here.

 In this case, the MTC UE transmits the uplink data according to the scheduling information corresponding to the MTC UE, the received resource information, and the closed loop power control command to adjust the transmission power.

 In the foregoing embodiment, the network side may dynamically indicate the scheduling information by using a new DCI. The format of the DCI is as described in Embodiment 2-4, and details are not described herein again.

 In this embodiment, the network side may also update the resource information and indicate by existing signaling. In this way, the MTC UE detects the new DCI in the common search space, and also detects the existing signaling to acquire new resource information. For example, the resource information of the update is detected in a UE-specific Search Space (USS).

 In this case, the method further includes: receiving resource information notified by the network side; and updating the obtained resource information of the network side configuration using the received resource information.

 It can be seen that the MTC UE can detect the signaling sent by the network side to obtain the scheduling information corresponding to the MTC UE. In addition, the updated resource information can be obtained by detecting the existing information.

 It will be understood by those skilled in the art that all or part of the steps in the foregoing embodiments may be implemented by a program to instruct related hardware, and the program may be stored in a computer readable storage medium, and the program is executed. All or part of the steps in the foregoing embodiment may be included. The storage medium may include: ROM, RAM, magnetic disk, optical disk, and the like.

The embodiment 13 of the present invention further provides a network system, where the network system includes the base station according to Embodiment 8 and the user equipment described in Embodiment 12.

 Figure 9 is a block diagram showing the construction of a network system in accordance with Embodiment 13 of the present invention. As shown in FIG. 9, the base station (eNB) and the MTC UE are included. As shown in FIG. 9, only two MTC UEs, namely, MTC UE1 and MTC UE2, are illustrated, but in actual networks, the number of MTC UEs may be arbitrary, assuming that the two MTC UEs belong to one group. The two-dot chain line indicates that downlink data is received; the dotted line indicates that uplink data is transmitted; the solid line indicates signaling and resource information and identification information delivered by the base station.

 For example, the same group of MTC UEs may be MTC UEs for smart metering and placed in a residential home, such as MTC UEs in the same residential building.

 On the network side:

 The base station (eNB) is an MTC UE packet, and determines the number of MTC UEs included in each group of MTC UEs according to the load size of the dynamic signaling and the field information carried by the signaling, and allocates a group identifier and each of each group of MTC UEs. a user label of the MTC UE; the base station configures resource information for each MTC UE in each group of MTC UEs in advance for the MTC UE, as shown in Embodiment 2-4;

 The base station notifies the MTC UE of the group identifier and the user label and the configured resource information by using RRC signaling; the base station passes the DCI of the new format, Table 3, Table 5, Table 7, Table 8, and Table 9, and other related information. That is, the scheduling information dynamically indicates the MTC UE. The CRC of the new format is scrambled using the group identifier and mapped to the common search space.

 If the configured resource information needs to be updated, the base station side configures the updated resource information, and notifies the MTC UE through the existing DCI signaling, such as DCI format 0/4.

 On the user device side:

 The DCI signaling is carried by a legacy PDCCH or an enhanced PDCCH (ePDCCH), and the search space appears as a set of a series of PDCCH candidates (or ePDCCH candidates), and the physical meaning represents a set of locations where the PDCCH (or ePDCCH) may occur.

 The user detection process is as follows:

 Each MTC UE (such as MTC UE1 and MTC UE2) receives a group ID (Group ID) from the eNB and a user label (UE-index) of the MTC UE in the group; and each MTC UE receives the eNB from the eNB. Pre-configured resource information carried by RRC signaling.

The above data transmission is taken as an example, and the MTC UE listens to the new uplink DCI format sent by the base station. The MTC UE monitors the new uplink DCI format, and the detection process is as follows: On the subframe of the DCI signaling sent by the intercepting eNB, the MTC UE with the group identifier blindly detects the DCI signaling of the format in the corresponding common search space by using the group identifier, and uses the group identifier to the DCI signaling. The CRC is descrambled, and then performs cyclic redundancy check on the DCI signaling according to the CRC, to obtain scheduling information corresponding to the MTC UE group, and then the MTC UE searches for the user in the corresponding scheduling information according to the user label. The scheduling information corresponding to the label.

 If the Transmitter Power Control Command (TPC command) of the scheduled MTC UE is transmitted by the DCI 3/3A, the CRC will use the identifier, for example, when the DCI 3/3A is sent on the network side. The TPC-PUSCH-RNTI performs scrambling. Therefore, the MTC UE uses the TPC-PUSCH-RNTI for blind detection in the corresponding common search space to obtain the TPC commando.

 The MTC UE can also perform blind detection using the user identity C-RNTI in a user-specific search space to obtain updated configuration information. For example, a dynamic uplink scheduling DCI format 0 (or DCI format 4) is detected, and the content of the corresponding field information covers the pre-configured resource information. For example, the resource location and quantity information indicated by the resource allocation block field is different from the pre-configured value of the eNB, and the scheduled MTC UE sends the uplink data on the dynamically notified RB resource location.

 In addition, the case of receiving downlink data is similar to the above, and details are not described herein again.

 Embodiments of the present invention also provide a computer readable program, wherein when the program is executed in an information transmitting apparatus or a base station, the program causes a computer to execute in the information transmitting apparatus or base station as in Embodiment 1 and an embodiment 2 The method of transmitting information.
