DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood that the present invention is not intended to be limited to the specific embodiments but includes all changes, equivalents, and alternatives included in the spirit and scope of the present invention.

Hereinafter, a scheduling apparatus in LTE object communication according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a configuration diagram of an LTE network according to an embodiment of the present invention, and FIGS. 2 to 6 are block diagrams for explaining FIG. 1 in detail.

Hereinafter, a scheduling apparatus in an LTE object communication according to an embodiment of the present invention will be described with reference to FIG. 1 to FIG.

First, referring to FIG. 1, an LTE network structure according to an embodiment of the present invention includes a BS and a terminal. In particular, when a macro cell and a D2D channel are separately allocated to each other, a new frequency can be allocated and used.

When the macrocell and the D2D channel are simultaneously allocated, inter-terminal communication can use at least one of the subchannel addition and the utilization of the physical channel being used in the macrocell. A channel management technique, and a duplexing method may be used.

In addition, synchronization between the terminals can be provided in the uplink, provided in the downlink, and used in at least one of uplink and downlink simultaneously.

The first terminal 110 and the third terminal 130 are located at the cellular link radius of the first base station 310 and the fourth terminal 240 and the fifth terminal 250 are located at the second base station 310. [ Lt; RTI ID = 0.0 > 320 < / RTI >

The third terminal 130 is located at a distance that allows D2D communication with the first terminal 110, the second terminal 120, and the fourth terminal 240. The D2D link between the third terminal 130 and the first terminal 110 is located in the same first base station 310 and the D2D link between the third terminal 130 and the fourth terminal 240 is located in another cellular radius, The D2D link of the third terminal 130 and the second terminal 120 includes a second terminal 120 that is not located in any cellular radius and a third terminal 130 that is located in a cellular radius of the first base station 310 have.

Here, the cellular link channel used between the first base station 310 and the third terminal 130 and the D2D link channel used by the third terminal 130 and the fourth terminal 240 may be separately allocated or allocated at the same time .

For example, when the same cellular link channel used between the first base station 310 and the third terminal 130 and the D2D link channel used by the third terminal 130 and the fourth terminal 240 use the same frequency, , PDCCH, PUSCH, and PUCCH may be separately allocated.

In particular, the first base station 310 can schedule a time slot allocation for transmission of a synchronization signal, a discovery signal, and a HARQ for the D2D link channel used by the third terminal 130 and the fourth terminal 240 have.

The synchronization signal transmitted by the first base station 310 may be used simultaneously with the information of the cellular link of the first base station 310 but may be synchronized with the synchronization signal used by the third terminal 130 and the fourth terminal 240, A discovery signal, and a time slot for transmission of HARQ can be scheduled so that a time slot does not overlap with a cell link channel used between the first base station 310 and the third terminal 130. [

Meanwhile, if the D2D link channel used by the third terminal 130 and the fourth terminal 240 uses a different frequency than the third terminal 130 and the third terminal 130, PDCCH, PUSCH and PUCCH OFDM symbols of the PDSCH, the PDCCH, the PUSCH and the PUCCH may be dedicated for scheduling by the third terminal 130 or the fourth terminal 240.

Meanwhile, during the D2D communication between the third terminal 130 and the fourth terminal 240, interference from the first base station 310 and the first terminal 110 is avoided and used. In particular, when performing the D2D communication between the third terminal 130 and the fourth terminal 240, the third terminal 130 transmits the synchronization signal received by the first base station 310 to the first base station 310, Link channel to the fourth terminal 240, to the fourth terminal 240 via the downlink channel used by the first base station 310 or to the uplink downlink channel used by the first base station 310, Channel to the fourth terminal 240 at the same time.

2 is a configuration diagram of a dual connection when the first base station 310 of FIG. 1 operates as a primary base station 101 and the second base station 320 operates independently as a secondary base station 201. FIG.

The master eNB 101 and the secondary eNB 201, which are used for the dual connection, are individually connected to the core network.

Therefore, the main base station 101 and the secondary base station 201 are independent from each other, and in particular, all of the protocols are characterized in that the base station 101 and the secondary base station 201 are not separated and combined in communication with the two base stations.

Here, the Packet Data Convergence Protocol (PDCP) is one of LTE's wireless traffic protocol stacks for performing IP header compression and decompression, transmission of user data, and sequence number maintenance for a radio bearer.

In addition, RLC (Radio Link Control) is a protocol stack for controlling wireless connection between PDCP and MAC.

And MAC (Media Access Control) is a protocol stack supporting multiple access of wireless channel.

3 illustrates a case where the first base station 310 of FIG. 1 operates as the primary base station 101 and the second base station 320 operates as the secondary base station 201 and the data is separated and combined through the primary base station 101 As shown in FIG.

That is, the main base station 101 and the secondary base station 201 used for the dual connection are connected to the core network, only the primary base station 101 is connected to the core network and the secondary base station 201 is connected to the primary base station 101 To the core network.

Therefore, the main base station 101 performs separation and combining for data communicated in the core network. That is, data separated from the main base station 101 is transmitted to the secondary base station 201 or data received from the secondary base station 201 is combined and communicated through the core network.

4 is a configuration diagram showing details of a case where the secondary base station 201 of FIG. 2 and FIG. 3 is disconnected from the terminal 301. FIG.

That is, the scheduling system in the LTE object communication includes a main base station 101, a main base station 101 for performing data communication with the terminal 301 by allocating radio resources to the terminal 301, And a terminal 301 for communicating data with the main base station 101 and the sub base station 201 at the same time and resetting the radio resource control when the link with the secondary base station 201 is disconnected.

Herein, when the terminal 301 is not normally connected to the secondary base station 201, the terminal 301 informs the primary base station 101 of the connection state information, and the primary base station 101 informs the secondary base station 201 of the connection state information And informs the link state information between the base station 201 and the terminal 301.

Similarly, when there is an abnormality in connection with the main base station 101, the terminal 301 performs radio resource control resetting and reports the report to the secondary base station 201 so that the secondary base station 201 transmits a connection abnormality .

At this time, the communication between the main base station 101 and the secondary base station 201 may add information to a frame in the X2 interface or use a broadband network, or may communicate using a wireless backhaul if not connected by wire. Frame information may use a signaling system including a link state header, a link state, a base station ID, and a terminal ID indicating a link state of the main base station 101 and the secondary base station 201.

Therefore, when there is an abnormality in the connection between the main base station 101 and the secondary base station 201, the terminal 301 reports it to either the primary base station 101 or the secondary base station 201, The base station reporting the connection informs the base station that the connection is abnormal and the connection state with the terminal 301 can be checked.

On the other hand, when both the main base station 101 and the secondary base station 201 are abnormal in connection, the terminal 301 reestablishes the radio resource control so that it can communicate through the base station.

FIG. 5 is a detailed diagram showing a case where the transmission power of the mobile station 301 is allocated to the main base station 101 or the secondary base station 201 of FIG. 2 and FIG.

That is, the scheduling system in the LTE object communication includes a main base station 101, a main base station 101 for performing data communication with the terminal 301 by allocating radio resources to the terminal 301, And sets a transmission power upper limit value ratio of the primary base station 101 and the secondary base station 201 based on a statistical analysis of power to be transmitted to the primary base station 101 and the secondary base station 201 And a terminal 301.

The statistical analysis analyzes the transmission power ratio based on the average power transmitted by the terminal 301 to the main base station 101 and the secondary base station 201. The terminal 301 analyzes the transmission power ratio based on the average power transmitted from the primary base station 101 and the secondary base station 201 ) To report the upper limit of the transmit power.

That is, the mobile station 301 transmits the maximum power to the primary base station 101 and the secondary base station 201 based on the maximum power to be transmitted from the mobile station 301 and the average value of the transmission power to be sent to the primary base station 101 and the secondary base station 201 201).

For example, the ratio of power to be transmitted to the main base station 101 and the sub-base station 201 is set to 3: 1, 2: 2, 1: 3, and the like.

As another example, in distributing the power to be transmitted, it is very important to maintain the connectivity with the main base station 101 or to transmit the control signal to the main base station 101. Therefore, And can allocate the remaining power to transmit / receive data to / from the secondary base station 201.

As another example, the available power when transmitting data to the secondary base station 201 may change dynamically. That is, the Modulation and Coding Scheme (MCS) value to be used may vary depending on the available power even if the radio channel is not changed.

At this time, if the power allocation and the MCS value are changed at the same time, it may cause a data transmission error, so that the power allocation change and the MCS value change may not be performed at the same time.

Alternatively, in order not to cause a data transmission error when the power allocation and the MCS value are simultaneously changed, the reporting period of the CQI (Channel Quality Indicator) for changing the MCS, which is a feedback signal system, can be set not to occur simultaneously with the change of the power allocation.

On the other hand, if at least one of the margins of the maximum value of the terminal, the power ratio to be used, the maximum transmission power of each base station according to the power ratio, and the maximum power that can be transmitted by each base station, ) And the secondary base station (201).

6 is a configuration diagram showing details of a case where the terminal 301 is randomly accessed by the main base station 101 or the sub-base station 201 of FIG. 2 and FIG.

That is, the scheduling system in the LTE object communication includes a main base station 101, a main base station 101 for performing data communication with the terminal 301 by allocating radio resources to the terminal 301, And at least one of the primary access point 101 and the secondary access point 201 to either of the primary access point 101 and the secondary access point 201 that performs random access by triggering or a random access without triggering And a terminal (301) for transmitting to any one of them.

Here, the triggering is performed by any one triggering command of PDCCH, MAC, and RRC, and the secondary base station 201 includes a base station that can access the primary base station 201 among the base stations that can operate as the secondary base station 201.

Here, the random access is transmitted in the form of a content preamble, an initial access, a radio resource control message, and a terminal ID.

That is, in the random access, the terminal 301 transmits the initial access, the establishment and re-establishment of the radio resource control to the main base station 101 or the secondary base station 201, It is possible to send random access to either the main base station 101 or the secondary base station 201 or to transmit the random access to the primary base station 101 or the secondary base station 201 at the same time.

At this time, random access may be transmitted through PDCCH, MAC, or radio resource control (RRC) triggering from the primary base station 101 or the secondary base station 201, but may also be transmitted through the terminal itself triggering.

In addition, random access can be transmitted using the remaining power excluding the power distributed in the uplink for random access.

Meanwhile, when the main base station 101 or the secondary base station 201 is newly turned on, peripheral terminals including the terminal 301 perform random access at the same time, thereby causing an error in data communication due to random access.

Therefore, when the main base station 101 or the sub-base station 201 is newly turned on to reduce the influence, the terminal 301 can perform random access using a random time of about 10 seconds. Here, 10 seconds is a maximum random access time that can be varied according to the number of terminals and the number of base stations, and the maximum random access time can be any value within 1 second to 60 seconds depending on the environment.

The mobile station 301 can use multiple antennas to identify the location of transmission from the main base station 101 or the secondary base station 201 and perform random access in the direction of the primary base station 101 or the secondary base station 201 Interference effects can be minimized.

Alternatively, when the positions of the main base station 101 and the secondary base station 201 are not accurate, the terminal 301 may sweep 360 degrees and perform random access.

The response by the command responds to the information held in the object communication module 100 by the command of the base station 200 by the object communication module 100. The command uses 20 bytes or less and the response uses 100 bytes or less. Second.

When an event is generated in the object communication module 100, the report by the occurrence of an event is reported to the base station 200 within 3 seconds to 5 seconds using information within 100 bytes, and the periodic report is 100 bytes And reports to the base station 200 the information within the range.

On the other hand, the object communication can be transmitted in a bandwidth of 1.4 MHz by using a single antenna without exceeding 1,000 bits.

The object communication module 100 may use 25,344 bits for the soft buffer for communication with the base station 200 and may drive the RF circuit using one oscillator.
