2 is a block diagram illustrating a configuration of an SHF / EHF band wireless transmission apparatus using a multilevel cell configuration according to an embodiment.

The SHF / EHF band wireless transmission apparatus 200 using the multilevel cell configuration utilizes an overlapping topology using a multi-stage relaying method between a terminal and a base station in an SHF / EHF band network environment, and at least one beam at most terminal locations. A multi-stage relay base station topology can be configured to secure a path, thereby creating a communication environment between the terminal and the base station.

The SHF / EHF band wireless transmitter 200 through the multilevel cell configuration may include a list manager 210, a path searcher 220, and a scheduler 230.

The list manager 210 may receive and manage a first list associated with an SHF / EHF band signal from a terminal connected to a wireless network.

The wireless network may include a first network performing a pivotal role, and a second network performing at least one of configuration / maintenance / decommission of the network by using limited assistance of the first network.

The first list may include at least one of information on a base station using a signal of the SHF / EHF band adjacent to a terminal connected to a wireless network and information on the terminal.

In addition, the first list may be periodically updated to secure a visible communication path according to the use of the SHF / EHF band.

The path search unit 220 may select a path having a communication quality value greater than or equal to a first threshold by referring to the first list.

The first threshold is a reference value for communication quality measured for at least one communication path included in the first list, and may be used for selecting a communication path.

When the selected route is unsuccessful, the route searching unit 220 may secure a visible distance by changing to another route in real time based on the first list.

However, if the path does not exist at all (the path having a communication quality value greater than the first threshold value does not exist), the path search unit 220 may switch to the cellular band frequency instead of the SHF / EHF band. Can be.

The scheduling unit 230 may schedule and allocate radio resources of an available SHF / EHF band for the selected path.

A description of the visible path search using the SHF / EHF frequency band will be described later with reference to FIG. 5.

The scheduling unit 230 may allocate a radio resource by separating a control channel and a traffic channel.

In this case, the cellular frequency band and the SHF / EHF band can be used at the same time, and the stable cellular frequency band, which basically does not require visibility, is used for the control channel, and the SHF / EHF frequency band, where the visible distance is required, is used for high-speed traffic. By allocating for a channel, it is possible to provide the maximum wireless transmission speed and the quality of service desired by the subscriber in a multi-stage relay environment where the visible distance is secured.

Table 1 shows a resource allocation scheme for a control channel and a traffic channel used between a terminal and a base station in a wireless network environment using a cellular band and a SHF / EHF band in common.

Since the UE operates in a multi-band / mode, the cellular band or the SHF / EHF band may be set to a use mode as shown in Table 1 according to a radio wave environment (including LoS) or QoS in the initial communication attempt.

Referring to Table 1, there are two methods of initial mode and mature mode, which are different frequency bands used for initial call setup and traffic allocation.

First, Initial mode uses the cellular band for initial call setup, but then allocates the SHF / EHF band for traffic allocation, or assigns cellular band for the initial super and slow traffic, and then assigns the cellular band for high speed heavy user traffic. In this case, the SHF / EHF band is additionally allocated.

According to an embodiment, the initial mode may be a method in which a common resource manager of a central base station existing in a central network is determined based on a multi-path finder with the help of a terminal.

In the mature mode, the SHF / EHF band is allocated to both initial call setup and all kinds of traffic thereafter.

The SHF / EHF band wireless transmission apparatus 200 through the multilevel cell configuration includes a 3GPP HSPA series system, such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), and the Mobile WiMax system of the IEEE. It may be partially applied to cellular systems that are constructed and new mobile communication systems after the fourth generation.

The path manager 320 may receive and combine at least one path selected based on the first list.

4 is a diagram illustrating a multi-stage cell configuration in which a central base station and a relay base station are physically overlapped in a central network wireless communication environment using an SHF / EHF band according to an embodiment.

The beamforming at the central base station 401 covers the cell indicated by cell layer 1 404, the beamforming at relay base station 402 covers the cell indicated by cell layer 2 405, and the relay base station ( Beamforming at 403 may cover the cell represented by cell layer 3 406.

Accordingly, the mobile terminal, the mobile group, or the fixed group can form a multi-beam with the central base station 401, the relay base station 1 402, and the relay base station 2 403 according to their respective positions. It can be connected to the base station through three beams at the same time.

Each cell layer of FIG. 4 may dynamically reduce or enlarge a corresponding coverage according to a communication environment such as a state of a terminal in a cell, and may be set to operate in a limited manner as needed to reduce power consumption.

FIG. 5 is a diagram illustrating an N-level topology configuration for securing one or more communication paths to enable communication between a central base station and a mobile station in a wireless communication environment using the SHF / EHF band according to an embodiment.

The topology based sight line search as shown in FIG. 5 may be performed by the following 3-steps.

First, in step 1, in order to secure a multipath, the mobile station 511 receives all pilot signals in the SHF / EHF band transmitted by adjacent base stations (the central base station 501 or the relay base station 509). Measure the signal and, together with its identification, 'measure list of received pilots' (SIR (path (i)), i = 1 ~ n, n: number of pilot signals in the received SHF / EHF bands). Report to common resource manager (CRM) 502.

Then, in step 2, the common resource manager (CRM) 502 selects paths having a communication quality (SIR (i)) equal to or above a predetermined threshold (usually up to y best paths), and then selects the selected communication paths. In this case, the radio resources of the available SHF / EHF band may be scheduled and allocated.

The measurement list generation of the received pilots and path selection having a communication quality above a certain threshold are performed by referring to Equations 1 and 2 below.

In Equation 1, n denotes the number of paths for which LoS is volunteered, and w in Equation 2 denotes the number of links constituting path (i).

Here, SIR (path (i)) corresponds to the SIR of the link having the smallest SIR value among the links constituting path (i), and the number of multipaths required for communication is generally limited to three or less. (3-Best Paths) is possible.

Radio resource allocation for the selected best paths may be determined in consideration of the quality of service to be provided (QoS, QoE, etc.) and the total path configuration cost of the radio links between the terminal and the CB to be communicated. The common resource manager (CRM) 502 may have additional functions.

The radio resource carrier frequency and bandwidth used for each link may be changed in real time according to the change of radio environment and service quality by applying the concept of Cognitive Radio System (CRS).

The terminal may report its positioning information (x, y, z) to the common resource manager in real time, so that the terminal may more easily search for neighbor base stations.

In step 3, when the communication path between the mobile station 511 and the central base station 501 is determined, the mobile station combines the selected best paths to reinforce the received signal or the seamless environment. can do.

However, the terminal and the base station should be operated so that communication disruption does not occur even in the following exceptional circumstances.

The terminal periodically searches for a pilot of a neighbor base station during communication, reports a 'receive pilot measurement list' to the common resource manager 502 of the central base station 501, and updates the list in real time, thereby providing instantaneous interference. Even if the secured visible communication path is blocked, it is possible to change to another communication path in real time.

The UE should support multi-band / mode, and neighbor base station discovery may be performed based on DRX (Discontinues Reception) or radio resource scheduling scheme.

However, in some cases, when there is no communication path between the terminal and the base station, it may be switched to the cellular band frequency in place of the SHF / EHF band.

Details of the wireless communication call setup procedure in the SHF / EHF band environment may apply a general cellular communication scheme (eg, 3GPP LTE-Advanced, etc.).

Similarly, in the case of uplink transmission from the terminal to the base station, the above scheme may be applied.

6 illustrates a radio resource allocation scheme for a control / traffic channel according to an embodiment.

Referring to FIG. 6, control information such as system control and call setup may use a cellular band, and traffic information such as ultra-high definition video transmission may use a resource allocation scheme that simultaneously utilizes a cellular band and an SHF / EHF band. .

In addition, not only the control signal but also a cellular band may be used for traffic that does not require much radio resources, and a SHF / EHF band may be used for traffic that requires a large amount of radio resources.

For example, a kind of discrete carrier that allocates cellular bands for initial call setup attempts and small traffic such as voice or general video, and additionally allocates SHF / EHF bands for heavy user traffic. A carrier aggregation method can be used.

Details of call setup procedures for SHF / EHF band resource utilization may apply to general cellular communication schemes (eg, 3GPP LTE-Advanced, etc.).

FIG. 7 is a diagram illustrating an operation for a traffic resource in a situation where a cellular band and an SHF / EHF band are used in common according to an embodiment.

As shown in FIG. 7, when the cellular band and the SHF / EHF band are commonly used, two modes, a mode 1 and a mode 2 may be operated.

Mode 1 is for using the same system irrespective of the frequency band. The mode 1 differs only in the cellular band or the SHF / EHF band depending on the radio wave environment (including the LoS environment) or the quality of service (QoS, QoE, etc.) Can switch

Mode 2 is for a case where the frequency band and the system to be used are different, and different radio transmission methods (RAT: Radio Access Technology) are used depending on the radio wave environment (including the LoS environment) and the quality of service (QoS, QoE, etc.) Switching, such as LTE systems or systems using the SHF / EHF band.
