M288010 四、創作說明（1) 技術領域 本創作是關於一種無線通訊，本創作尤其是關於一種使用 智慧天線以建立回程網路的裝置及系統。 先前技術 在無線通訊系統中最重要的一個議題便是藉由降低干擾來 增加系統容量，陣列天線（亦稱作智慧天線）已經被發展出 來以改善容量並且降低干擾。智慧天線使用複數個天線元 件以產生指向性的電波，其僅向一特定方位發送信號。藉 智慧天線，因為信號在涵蓋區域内發送至一狹窄區域， 無線通訊系統便可增加容量並減少干擾。由於傳輸器可增 加指向電波的傳輸功率等級，而不會造成對其他傳輸器或 接收器的過份干擾，例如無線傳輸/接收單元（以下簡稱 WTRU)及基地台，因此增加了整體系統容量。 一無線通訊系統通常包含複數個節點，例如基地台及無線 網路控制器等等，節點典型地互相以有線方式連接，例如 網狀網路或是蜂巢式網路，節點間互相通訊並傳輸訊息， 例如回程訊息。 然而，有線連接在建立回程網路上的缺點便是太過昂貴、 時間消耗、以及網路的變型或修改沒有彈性。尤其是網狀 網路必須要求節點互相連結，當新節點加入至網狀網路 時，為回程建立新連接至該新節點就是很大的負荷（在成M288010 IV. Creation Notes (1) Technical Field This creation is about wireless communication. This creation is especially about a device and system that uses a smart antenna to establish a backhaul network. Prior Art One of the most important issues in wireless communication systems is to increase system capacity by reducing interference. Array antennas (also known as smart antennas) have been developed to improve capacity and reduce interference. Smart antennas use a plurality of antenna elements to produce directional electrical waves that only transmit signals to a particular orientation. With smart antennas, wireless communication systems increase capacity and reduce interference because signals are sent to a narrow area within the coverage area. Since the transmitter can increase the transmission power level directed to the radio waves without causing excessive interference to other transmitters or receivers, such as WTRUs and base stations, the overall system capacity is increased. A wireless communication system usually includes a plurality of nodes, such as a base station and a wireless network controller, etc., and the nodes are typically connected to each other in a wired manner, such as a mesh network or a cellular network, and nodes communicate with each other and transmit messages. , such as a backhaul message. However, the disadvantage of wired connections in establishing backhaul networks is that they are too expensive, time consuming, and inflexible or modified by the network. In particular, the mesh network must require nodes to be connected to each other. When a new node joins the mesh network, it is a big load to establish a new connection to the new node for the backhaul.

Creation Instructions (4) The data can be transmitted to different nodes by another route at different times, especially in the mesh network. Since the backhaul link can change over time, the smart antenna can be adjusted so that it can be connected to different It is important that nodes do not interfere excessively with other nodes. At least a portion of the nodes 1 0 2a-η provide at least one smart antenna (described in detail later), and in addition to the general download transmission to and from the WTRUs, the smart antenna is used to transmit the backhaul data to other nodes 1 0 2 a - η, these nodes 1 Ο 2 a - η have the ability to generate a plurality of pointing radio waves, and I direct the radio waves to the azimuth direction. Network 100 is expected to include nodes with wired connections, as well as nodes that use smart antennas for wireless backhaul connections, which can be reconfigured and point to different nodes because of the connections established using smart antennas, thus increasing system resiliency. However, at least one node will have a wired connection to the core network 110 and a wireless connection to other nodes to provide a connection between the wireless node group and the substantially wired core network, at least a portion of the node 1 0 2a-η also provides the ability to transmit backhaul information over wired or private links. Nodes with wired and wireless backhaul connections (shown as 1 0 2 η on the picture, hereafter referred to as the hybrid node) Θ Connected to the wired core network 1 1 0. In other words, when the node wirelessly transmits the backhaul information via the help of the smart antenna, the backhaul information will eventually be routed to the core network through the hybrid node 1 0 2 η, so the hybrid node 1 0 2 η can connect through the wireless backhaul. Receiving and sending backhaul information to the node, and receiving and sending backhaul information to the core network 110, thereby forming a bridge.

M288010 四、創作說明（5) 在一實施方式中，節點1 02a-η具有複數個如同第4圖所示 的預設電波1 0 9 a - h，且在複數個電波1 0 9 a - h間選擇一個以 便指向一傳輸或接收。第4圖所示八個方為電波，其皆可 由每一節點1 02a-η產生，值得注意的是第4圖所示的電波 只是一個範例，任何數量的電波、電波模式或是任何形式 的模式皆可執行。 在另一個實施方式中，每一電波109a-h可即時產生和指 ，而不需要從預設的位置集合中挑出。 節點1 02a-η可動態地或從複數個有效位置中選擇電波 109a-h方向，這在系統容量、資料生產量、干擾等等方面 提供了最佳的效能。節點102a-η通常固定於一特定位置， 因此一旦兩節點1 02a-η設定好一電波1 09a-h及組態，指向 和組態便會儲存且之後不需修改變可使用。因為無線環境 及流量負載長期下可能會有所改變，每一節點1 02a-η需有 能力提供超過一個電波1 09a-h以連結至其他節點1 02a-η， 因此每一節點1 02a-η監控接收自其他節點1 02a-η的信號， #便判定無線環境，並動態地調整該電波指向及信號組態 以達到系統效能最佳化。 該系統運作之一實施方式如下：一第一選擇節點，例如節 點1 0 2 a，產生一電波並引導其朝向其他選擇節點，例如M288010 IV. Creation Description (5) In an embodiment, the nodes 1 02a-η have a plurality of preset electric waves 1 0 9 a - h as shown in Fig. 4, and at a plurality of electric waves 1 0 9 a - h Choose one to point to a transmission or reception. The eight squares shown in Fig. 4 are radio waves, which can be generated by each node 102a-η. It is worth noting that the radio waves shown in Fig. 4 are only an example, any number of radio waves, radio wave patterns or any form. The modes are all executable. In another embodiment, each of the waves 109a-h can be generated and indexed instantaneously without the need to pick from a predetermined set of locations. Nodes 1 02a-η can select the wave 109a-h direction dynamically or from a plurality of effective positions, which provides optimum performance in terms of system capacity, data throughput, interference, and the like. The nodes 102a-n are typically fixed at a particular location, so once the two nodes 102a-n have set a radio wave 109a-h and configuration, the pointing and configuration are stored and can be used without modification. Because the wireless environment and traffic load may change in the long term, each node 102a-η needs to be able to provide more than one radio wave 1 09a-h to connect to other nodes 102a-η, so each node 1 02a-η Monitor the signals received from other nodes 1 02a-η, # determine the wireless environment, and dynamically adjust the radio pointer and signal configuration to achieve system performance optimization. One embodiment of the operation of the system is as follows: a first selection node, such as node 1 0 2 a, generates an electric wave and directs it toward other selection nodes, for example

Creation Note (6) 10 2b, which can be achieved by adjusting the composite weights for the antenna array elements, as is typically done by radio waves forming an antenna array. At the same time, node 1 0 2 a measures the quality of link A to node 1 0 21 b. The quality of link A can be determined by signal noise ratio, bit or frame error rate, or other measurement quality indicator. measuring. The transmitting node 1 0 2 a finds the best antenna radio wave pointing, the optimal weight combination to maximize the link quality, and stores the link quality measurement and the corresponding radio wave direction (weight). The transmitting node 1 0 2 a does these things for all neighboring nodes and stores the corresponding quality and radio wave information. f. Nodes 02a-n can be flexibly and wirelessly connected or disconnected from other nodes 102a-n by selecting one or more of the other nodes 102a-n. In FIG. 1, the first node 102a transmits a message to the second node 1 0 2 b using the pointing wave A, and transmits the message to the fourth node 1 0 2 d using the pointing wave B, pointing to the wave A and the pointing wave. B is independently controlled and can be transmitted at the same time. Since each of the pointing wave A and the pointing wave B are transmitted only to a specific direction, it does not cause excessive interference to other nodes 102a-n or WTRUs. Figure 2 shows a block diagram of node 2 0 2 according to this creation. The node 202 includes a smart antenna 2 0 4, a controller 2 0 6 , a memory 2 0 8 and a non-linear wired link 2 1 0. The wired link 210 can be linked to the core network 1 10 or other nodes. The node 202 performs a signal processing algorithm to accommodate user mobility, changes in the radio frequency environment, and multipath of common channel interference. A Radio Resource Management (RRM) function is performed by the controller 206 to determine how the radio resource should be configured in the node 202.

第11頁 M288010 四、創作說明（7) 智慧天線2 0 4包含複數個天線元件（圖上未示），以在控制 器2 0 6的控制下產生複數個指向電波，每一電波作為介於 該節點2 0 2及其他節點之間的無線連結，如同上文所述， 因為節點2 0 2典型地為固定在一特定位置，因此兩節點間 的電波指向和組態便可預先設定並儲存於記憶體2 0 8中。 記憶體2 0 8維護一個包含其他節點、電波指向及每一其他 節點的組態資訊的表，當該節點2 0 2需要傳輸訊息至其他 節點，例如回程資料，該控制器2 0 6便會由該記憶體2 0 8中 取對應的電波指向和組悲資訊’並產生一指向電波引導 至一特定方向，且使用該電波傳輸該訊息。 在混合節點1 0 2 η方面，此程序在該智慧天線2 0 4幫助下建 立與其他節點的無線連結之後。當混合節點1 〇 2 η建立回程 連結至該核心網路1 1 0或其他節點時，並不需要組態資訊 或是電波選擇，因為有線鍊結2 1 0實體上是固定的，且總 是提供兩節點之間的連結。 根據本創作，智慧天線2 0 4較佳地具有多電波濘力，其中 一電波可獨立使用，一節點2 0 2產生超過一個的指向電 波以同時傳輸回程資料至複數個其他節點。因為超過一 個指向電波可能在相同的涵蓋區域使用相同的頻率，因此 系統容量實質上也有所增加。Page 11 M288010 IV. Creation Instructions (7) Smart Antenna 2 0 4 contains a plurality of antenna elements (not shown) to generate a plurality of pointing waves under the control of controller 206, each of which acts as a The wireless connection between the node 2 0 2 and other nodes, as described above, because the node 2 0 2 is typically fixed at a specific location, the radio wave pointing and configuration between the two nodes can be pre-set and stored. In memory 2 0 8 . Memory 2 0 8 maintains a table containing configuration information of other nodes, radio pointers, and each of the other nodes. When the node 2 0 2 needs to transmit a message to other nodes, such as backhaul data, the controller 2 0 6 will The corresponding radio wave pointing and group sadness information is taken from the memory 202 and a pointing radio wave is directed to a specific direction, and the information is transmitted using the radio wave. In the case of the hybrid node 1 0 2 η, this procedure is followed by the wireless connection with other nodes with the help of the smart antenna 204. When the hybrid node 1 〇 2 η establishes a backhaul connection to the core network 1 10 or other nodes, no configuration information or radio wave selection is required, because the wired link 2 1 0 is physically fixed and always Provide a link between the two nodes. According to the present invention, the smart antenna 204 preferably has multiple radio waves, one of which can be used independently, and one node 2 0 2 generates more than one directed wave to simultaneously transmit backhaul data to a plurality of other nodes. Since more than one pointing wave may use the same frequency in the same coverage area, the system capacity is substantially increased.

Creation Description (8) Several nodes with several electric waves can be coupled together, which makes changing connections and dynamic adaptations in the wireless environment become very important. For example, two waves may be provided between two nodes for connection. If a wave is excessively interfered, the node may switch to another wave to transmit a message. The use of smart antennas makes the backhaul link between nodes flexible, because each node is configured to generate a plurality of pointing waves and can direct the pointing wave to any azimuth direction, so when a new node is added to the network 1 0 0 At that time, the existing node can establish a connection to the new node by simply setting a new radio wave direction and configuring the new ¥ point, in addition, when the existing node is removed by the network 1 0 0 The node can also easily remove the radio wave pointing and configuration information of the removed node from the memory of the memory. This creation makes it possible to create or remove links between nodes without the need for additional setup or removal of devices. It is worth noting that this creation can be performed on a mesh or cellular network. One of the strengths of mesh networks is their ability to generate new links and remove other links between nodes, relying on a number of factors, including traffic load, interference, and individual node performance. As shown in Fig. 1, a plurality of nodes 102a-η are coupled to each other using smart antennas, and line # between nodes 102a-n in Fig. 1 shows possible links AF, and control can be concentrated, thereby at least one The nodes act as control nodes to control the connections between the nodes, and the control can also be dispersed, whereby the control can be distributed over several nodes or all nodes. If a node is designated as a control node, the control node collects information about the traffic status and the performance of each node, and determines the traffic path for optimal transmission of information from one node to another.

At least one A portion of the nodes provides at least one smart antenna configured to generate a plurality of directed waves, and then independently direct the orientation (step 302). Each of the waves is used in addition to the traffic typically downloaded to the WTRUs and the traffic uploaded by the WTRUs. As a wireless link to other nodes, each node maintains a table containing other nodes and radio waves pointing and configuration information for transmission to other nodes (step 3 0 4 ). It must be noted that step 3 2 0 And 3 0 4 are typically executed according to the set system or reconfigured to perform actions to accept or delete nodes, and typically will not need to be formed under normal operation. When the source node needs to be transmitted to the target node, the source node extracts the radio wave pointing and configuration information of the target node from the memory, and uses the radio wave pointing and configuration information to generate a pointing wave (step 306). The node is selected to transmit backhaul data, and based on the quality of the link and other considerations such as traffic density, the transmitting node selects the radio wave (weight) from the table and will use it on the antenna. Because the environment may change, The procedure for measuring link quality and storing relevant information may require periodic execution, and the radio wave pointing adjustment is also necessary. The source node then transmits the generated directional wave to the target node (step 308). In a non-essential step, network changes may occur, whereby a new node may be added to the network, and an existing node may be in the network.
