Description
本發明有關於一種資源調控方法以及令設備可執行該方法之非揮發性設備可讀媒體，尤其是一種應用於授權輔助接入網路之小細胞設備上以調控傳輸時間的技術。 The present invention relates to a resource control method and a non-volatile device readable medium for enabling a device to perform the method, and more particularly to a technique for applying to a small cell device authorized to access an access network to regulate transmission time.
今日行動裝置蓬勃發展所帶來的網路傳輸需求，使得LTE(Long Term Evolution)技術不斷朝提升頻譜使用效率及頻段整合演進，其中的LTE授權輔助接入(License-assisted Access,LAA)技術亦是一極具潛力之技術。 The LTE (Long Term Evolution) technology continues to improve spectrum utilization efficiency and frequency band integration evolution, and the LTE License-assisted Access (LAA) technology also It is a technology with great potential.
授權輔助接入主要係利用既有LTE技術的載波聚合(Carrier Aggregation)技術框架，以將載波聚合延伸至免執照頻段，主要可應用於小細胞(Small Cell)設備上以增加與小細胞設備連結之用戶的傳輸速度。 Authorized auxiliary access mainly utilizes the Carrier Aggregation technology framework of the existing LTE technology to extend the carrier aggregation to the license-free frequency band, and is mainly applied to small cell (Small Cell) devices to increase connection with small cell devices. The user's transmission speed.
然而，目前LAA僅係一概念性的技術，其主要係透過先聽後送(Listen Before Talk)程序中來適當地操作授權輔助接入技術，即係小細胞設備在進行資料傳輸前會先聽取範圍內的用戶設備是否亦在進行資料傳輸，以避免封包碰撞之情形。 However, at present, LAA is only a conceptual technology, which mainly operates the authorized auxiliary access technology through the Listen Before Talk program, that is, the small cell device will listen to the data before transmitting it. Whether the user equipment in the range is also transmitting data to avoid the collision of packets.
而這種先聽後送的技術雖然有很高的發展性，但 實施於場域時，小細胞設備之間的聽取和傳輸範圍可能有所重疊，但小細胞設備彼此間用以聽取的能量偵測範圍不同，仍可能在傳輸資料時產生封包碰撞；抑或是，小細胞設備有可能使用相鄰頻道進行資料傳輸，若用戶設備濾波器不佳，亦可能產生封包碰撞。 Although this technology of listening and sending is highly developed, it is highly developed. When implemented in the field, the listening and transmission range between small cell devices may overlap, but the range of energy detection that small cell devices use to listen to each other may still cause packet collision when transmitting data; or Small cell devices may use adjacent channels for data transmission. If the user device filter is not good, packet collision may occur.
由此，若能發展出一種技術以解決授權輔助接入技術中小細胞設備之間的封包碰撞，應可提升整體系統之效能，使授權輔助接入技術能發揮其效能。 Therefore, if a technology can be developed to solve the packet collision between small cell devices in the authorized auxiliary access technology, the overall system performance should be improved, and the authorized auxiliary access technology can exert its performance.
本發明提供了一種授權輔助接入網路(License Assisted Access,LAA)之資源調控方法，其中，LAA係為長期演進技術(Long Term Evolution,LTE)家族中的一種技術。 The present invention provides a resource control method for a licensed Assisted Access (LAA) system, wherein the LAA is a technology in the Long Term Evolution (LTE) family.
該方法主要係透過授權輔助接入網路系統中的一無線基地設備來執行，該無線基地設備設置於一場域中，因授權輔助接入技術具有先聽後送之機制，其具有用以收聽的一能量偵測範圍，該方法至少包含下列步驟：於該無線基地設備預備傳輸資料至能量偵測範圍內的一行動裝置前，先根據該無線基地設備與該行動裝置之間的通道干擾狀態，以動態地決定一資料傳輸時間，該資料傳輸時間可表示為t+Bias TX (t)，該資料傳輸時間之調整可用以對該無線基地設備時頻資源進行管控，以使該無線基地設備操作授權輔助接入技術之效能提升。 The method is mainly implemented by a wireless base station in an authorized auxiliary access network system, and the wireless base station is set in a field, because the authorized auxiliary access technology has a mechanism of listening and sending, and has a mechanism for listening. An energy detection range, the method comprising at least the following steps: before the wireless base device prepares to transmit data to a mobile device within the energy detection range, according to a channel interference state between the wireless base device and the mobile device To dynamically determine a data transmission time, the data transmission time can be expressed as t + Bias TX ( t ), and the data transmission time adjustment can be used to control the time-frequency resource of the wireless base device, so that the wireless base device Operational authorization assisted access technology performance improvement.
其中，該行動裝置將持續地或離散地對該無線基地設備回饋其所接收資料是否正確，而在該無線基地設備預備傳輸資料至該行動裝置前(該時點為t)，若該時點該行動裝 置回饋的即時資料接收正確率(C i,t )大於行動裝置回請其在先前一定時間(T)內的近期資料接收正確率(C i,t-T )，則代表該無線基地設備與該行動裝置之間的通道干擾應較先前為低，故需減少該資料傳輸時間，即係將Bias TX (t)設為-△ T ，△ T 係為一預設時間值，以減少資源浪費。 Wherein, the mobile device will continuously or discretely feed back to the wireless base device whether the received data is correct, and before the wireless base device prepares to transmit the data to the mobile device (the point is t ), if the action is taken at the time The real-time data receiving correct rate ( C i,t ) of the device feedback is greater than the recent data receiving correct rate ( C i,tT ) of the mobile device in the previous certain time ( T ), which represents the wireless base device and the action co-channel interference between the devices should be lower than previously, so the need to reduce the data transmission time, i.e., the line Bias TX (t) is set to - △ T, △ T is a predetermined time-based values, in order to reduce waste of resources.
其中，若該時點該行動裝置回饋的即時資料接收正確率(C i,t )小於行動裝置回饋其在先前一定時間(T)內的近期資料接收正確率(C i,t-T )，則代表該無線基地設備與該行動裝置之間的通道干擾應較先前為高，故需增加該資料傳輸時間，即係將Bias TX (t)設為+△ T ，以有效利用時頻資源。 Wherein, if the real-time data receiving correct rate ( C i,t ) fed back by the mobile device at this time is less than the recent data receiving correct rate ( C i,tT ) of the mobile device feeding back within a certain certain time ( T ), The channel interference between the wireless base device and the mobile device should be higher than before, so the data transmission time needs to be increased, that is, the Bias TX ( t ) is set to +Δ T to effectively utilize the time-frequency resources.
其中，若該時點該行動裝置回饋的即時資料接收正確率(C i,t )已高於預設的一理想閾值(S TH )，表示目前該無線基地設備的時頻資源係處於操作授權輔助接入技術的最佳範圍中，或是先前一定時間(T)內並無資料傳輸，此時則維持該資料傳輸時間。 Wherein, if the real-time data receiving correct rate ( C i,t ) fed back by the mobile device is higher than a preset ideal threshold ( S TH ), it indicates that the current time-frequency resource of the wireless base device is in operation authorization assistance. In the best range of access technology, or no data transmission in the previous certain time ( T ), the data transmission time is maintained.
其中，於該資料傳輸時間係增加或維持時，則該無線基地設備在該資料傳輸時間內可透過免執照頻段對該行動裝置進行資料傳輸，藉此，可增加該無線基地設備的免執照頻段時頻資源使用率。 Wherein, when the data transmission time is increased or maintained, the wireless base device can transmit the data to the mobile device through the unlicensed frequency band during the data transmission time, thereby increasing the license-free frequency band of the wireless base device Time-frequency resource usage.
其中，於該資料傳輸時間減少時，則該無線基地設備在該資料傳輸時間內僅透過執照頻段對該行動裝置進行保證位元速率(Guaranteed Bit Rate,GBR)之資料傳輸，另外，非保證位元速率(non-Guaranteed Bit Rate,non-GBR)之資料則透過免執照頻段傳輸，藉此，可增加該無線基地設備的免執照頻段時頻資源使用率。 Wherein, when the data transmission time is reduced, the wireless base station transmits the data of the Guaranteed Bit Rate (GBR) to the mobile device through the license band only during the data transmission time, and the non-guaranteed bit The non-Guaranteed Bit Rate (non-GBR) data is transmitted through the license-free frequency band, thereby increasing the time-frequency resource usage rate of the unlicensed band of the wireless base device.
本發明更包含一種儲存有設備可執行指令之非 揮發性設備可讀媒體，其係設置於授權輔助接入授權輔助接入網路系統的一無線基地設備，所述指令使該無線基地設備可執行上述的授權輔助接入網路之資源調控方法。 The invention further comprises a non-stored device executable instruction a volatile device readable medium, which is disposed in a wireless base device that authorizes an auxiliary access authorization access network system, and the instructions enable the wireless base device to perform the resource control method of the authorized auxiliary access network .

以下將以實施例結合圖式對本發明進行進一步說明，圖1係為授權輔助接入網路的系統可能干擾問題之示意圖，圖中由左至右可見三個近似圓之範圍，其由左至右分別代表第三方無線網路(Wi-Fi)基地台A、第一小細胞(Small Cell SC)B以及第二小細胞C的資料傳輸範圍，其中，使用者設備(User Equipment)1、使用者設備2以及使用者設備3皆依附(attach)於第一小細胞B上進行資料傳輸，而使用者設備4 則依附在第二小細胞C上進行資料傳輸，其中，先將使用者設備1以及使用者設備4定義為已處於理想傳輸狀態。 The present invention will be further described by way of embodiments with reference to the accompanying drawings. FIG. 1 is a schematic diagram of a possible interference problem of a system for authorizing an auxiliary access network. The range of three approximate circles is visible from left to right in the figure, from left to right. The right represents the data transmission range of the third-party wireless network (Wi-Fi) base station A, the first small cell (Small Cell SC) B, and the second small cell C, respectively, wherein the user equipment (User Equipment) 1, used Both the device 2 and the user device 3 are attached to the first small cell B for data transmission, and the user device 4 Then, the second small cell C is attached to the data transmission, wherein the user equipment 1 and the user equipment 4 are first defined as being in an ideal transmission state.
若根據傳統技術實施，各基地台與小細胞操作先聽後送時使用的能量偵測範圍可能有所不同，或各基地台與小細胞可能透過鄰頻傳輸資料，此時將可能有兩種問題產生：首先，若第一小細胞B操作先聽後送的能量偵測時，其偵測到範圍內無其他設備使用相同傳輸通道，故其便開始資料傳輸，然而，因為第一小細胞B與第二小細胞C所使用的能量偵測臨界值不同，當第一小細胞B的偵測範圍較小時，其並無法偵測到第二小細胞C的即時傳輸狀態，此時，傳輸之封包將可能發生碰撞；或是，當第一小細胞B操作先聽後送的能量偵測時，其偵測到範圍內無其他設備使用相同傳輸通道，故其便開始傳輸資料，然而，因為第三方無線網路基地台A或是第二小細胞C正透過第一小細胞B傳輸頻道的鄰近頻道傳輸資料，若使用者設備2以及使用者設備3的濾波器不理想時，其接收到的資料封包就有可能發生錯誤。 According to the traditional technology implementation, the range of energy detection used by each base station and small cell operation may be different when the first base station is operated, and the base stations and small cells may transmit data through the adjacent frequency. The problem arises: First, if the first small cell B operates the energy detection after the first listening, it detects that no other device uses the same transmission channel, so it starts data transmission, however, because the first small cell B is different from the energy detection threshold used by the second small cell C. When the detection range of the first small cell B is small, it cannot detect the instantaneous transmission state of the second small cell C. The transmitted packet may collide; or, when the first small cell B operates the energy detection after the first listening, it detects that no other device uses the same transmission channel, so it starts to transmit data, however Because the third-party wireless network base station A or the second small cell C is transmitting data through the adjacent channel of the first small cell B transmission channel, if the filters of the user device 2 and the user device 3 are not ideal, Connect The data packets have errors may occur.
圖2為本發明授權輔助接入網路之資源調控方法的主要步驟示意圖，其主要係透過可動態調整的資料傳輸時間，以根據潛在的干擾來源調整時頻資源，使得基地設備操作授權輔助接入技術的效能提升。其第一步驟S201主要係將基地設備可進行資料傳輸之時間設為一動態值，其為t+Bias TX (t)，其中的Bias TX (t)即係預設的一調整參數用以決定基地設備操作授權輔助接入技術可進行傳輸之時間，而此Bias TX (t)係根據與基地設備通訊連結的接收設備所回饋的資料接收正確率來動態調整的。第二步驟S202係根據接收設備回報資訊來調整基地設備可進行資料傳輸之時間，其中，當 基地設備欲開始傳輸資訊前，若接收設備回報其即時的資料接收正確率高於先前的接收資料正確率時，則可能代表傳輸通道的干擾較低，此時，將t時間的調整參數Bias TX (t)設為-△ T ，其中，-△ T 為時間微調值，其係一正值，如此，基地設備的資料傳輸時間將減少，以妥善利用系統資源；相反地，當接收設備回報其即時的資料接收正確率低於先前的接收資料正確率時，則可能代表傳輸通道干擾較高，故須將t時間的調整參數Bias TX (t)設為+△ T ，以增加更多傳輸時間；另外，若接收設備回報其即時資料接收正確率在高於一理想閾值S TH 的範圍內，則Bias TX (t)將被設為0，因其代表此時基地設備係處於操作授權輔助接入技術的最佳範圍中。 2 is a schematic diagram of main steps of a resource control method for authorizing an auxiliary access network according to the present invention, which mainly adjusts time-frequency resources according to potential interference sources through dynamically adjustable data transmission time, so that base device operation authorization auxiliary connection The efficiency of the technology is improved. The first step S201 is mainly to set the time when the base device can perform data transmission to a dynamic value, which is t + Bias TX ( t ), wherein the Bias TX ( t ) is a preset adjustment parameter used to determine The base device operates to authorize the access control technology to transmit time, and the Bias TX ( t ) is dynamically adjusted according to the data receiving correct rate fed back by the receiving device connected to the base device. The second step S202 is to adjust the time when the base device can perform data transmission according to the feedback information of the receiving device. Before the base device wants to start transmitting information, if the receiving device returns its immediate data, the correct rate of receiving data is higher than the previous received data. At the time rate, it may represent that the interference of the transmission channel is low. At this time, the adjustment parameter Bias TX ( t ) of t time is set to -Δ T , where -Δ T is the time trimming value, which is a positive value, so The data transmission time of the base equipment will be reduced to properly utilize the system resources; conversely, when the receiving equipment returns its immediate data receiving accuracy rate is lower than the previous receiving data correct rate, it may represent that the transmission channel interference is high, so The adjustment parameter Bias TX ( t ) of t time must be set to +Δ T to increase more transmission time; in addition, if the receiving device reports that the real data receiving accuracy rate is within a range higher than an ideal threshold S TH , then Bias TX ( t ) will be set to 0 because it represents that the base equipment is in the best range of operational authorization access technologies.
圖3為本發明授權輔助接入網路之資源調控方法的細部步驟示意圖，步驟S301為在基地設備欲傳輸資料的時刻(t)，計算接收設備i的即時的資料接收正確率C i,T ，其中，C i,T 之計算方式為將統計時間T內接收設備i成功傳輸資料的次數除以統計時間T內設備i的所有傳輸次數。再進入步驟S302進行判斷，若t-T時間內基地設備沒有傳輸資料，則進入步驟S303將t時間的調整參數Bias TX (t)之值設為0。若t-T時間內基地設備有進行資料傳輸，則進入步驟S304，以將即時的資料接收正確率C i,T 之值與理想閾值S TH 作比較，其中，S TH 係為一種調整門檻，其值界於0至1之間。 FIG. 3 is a schematic diagram showing the detailed steps of the method for controlling the resource of the auxiliary access network according to the present invention. Step S301 is to calculate the instantaneous data receiving accuracy rate C i,T of the receiving device i at the time ( t ) of the base device to transmit data. where, C i, T, is calculated as the number of the receiving device i successful transmission of information within the time T divided by the total number of transfers within the time T i of the device. Going to step S302 again, if the base device does not transmit data in tT , the process proceeds to step S303 to set the value of the adjustment parameter Bias TX ( t ) of t time to zero. If the base device has data transmission in the tT time, the process proceeds to step S304 to compare the instantaneous data receiving accuracy rate C i,T with the ideal threshold S TH , wherein the S TH is an adjustment threshold, and the value thereof The boundary is between 0 and 1.
接續圖3，倘若C i,T 值大於理想閾值S TH ，則進入步驟S303將t時間的調整參數Bias TX (t)設為0。倘若t-T時間內基地設備有進行資料傳輸，且傳輸狀況資料接收正確率C i,T 值小於理想閾值S TH ，則進入步驟S305以判斷C i,T 值是否大於近期的資料接收正確率C i,t-T 值，若C i,T 值大於或等於C i,T 之值，代 表即時的資料接收正確率較高，此時進入步驟S306將t時間的調整參數Bias TX (t)設為t-T時間的調整參數Bias TX (t-T)再加上一負時間微調值-△ T ，以降低資料傳輸時間；相反的，若C i,T 值小於C i,T 之值，代表即時的資料接收正確率較低，則進入步驟S307將Bias TX (t)設為t-T時間的調整參數Bias TX (t-T)再加上一正時間微調值+△ T 。 Next, in FIG. 3, if the value of C i, T is greater than the ideal threshold S TH , the process proceeds to step S303 to set the adjustment parameter Bias TX ( t ) of t time to zero. If the base device has data transmission in the tT time, and the transmission status data receiving correct rate C i, the T value is less than the ideal threshold S TH , then the process proceeds to step S305 to determine whether the C i , T value is greater than the recent data reception accuracy rate C i , tT value, if C i, T value is greater than or equal to the value of C i, T , which means that the instantaneous data receiving accuracy rate is high, then proceeds to step S306 to set the t time adjustment parameter Bias TX ( t ) to tT time. adjustment parameters Bias TX (tT) plus the value of a negative time spinner - △ T, in order to reduce the data transmission time; the contrary, if C i, T value of less than C i, the value of T, representative of the correct instant data rate of the received is low, the process proceeds to step S307 Bias TX (t) to adjust the parameters Bias tT time TX (tT) plus a positive time trim value + △ T.
仍請參照圖3，其中，接續步驟S306的係為步驟S308，其係判斷t時間的調整參數Bias TX (t)是否大於等於零，若Bias TX (t)大於等於零，進入步驟S309，在資料傳輸時間t+Bias TX (t)內，基地設備將使用免執照頻段進行設備i的資料傳輸，而步驟S303的Bias TX (t)=0，故其亦將接續至此步驟S309。另外，接續步驟S307的係為步驟S310，在資料傳輸時間t+Bias TX (t)內，基地設備將使用執照頻段進行設備i的保證位元速率(GBR)資料傳輸，並使用免執照頻段進行設備i的非保證位元速率(non-GBR)資料傳輸。此方法步驟可反覆實施以持續調整基地設備的資料傳輸時間，以使其能處於操作授權輔助接入技術的最佳範圍中。 Still referring to FIG. 3, wherein the step S308 is followed by step S308, which determines whether the adjustment parameter Bias TX ( t ) of t time is greater than or equal to zero, and if Bias TX ( t ) is greater than or equal to zero, proceeds to step S309, where data is transmitted. During time t + Bias TX ( t ), the base device will use the unlicensed band for data transmission of device i , and Bias TX ( t )=0 in step S303, so it will also continue to step S309. In addition, the step S307 is followed by step S310. During the data transmission time t + Bias TX ( t ), the base device uses the licensed frequency band to perform the guaranteed bit rate (GBR) data transmission of the device i , and uses the license-free frequency band. Non-guaranteed bit rate (non-GBR) data transfer for device i . This method step can be repeated to continuously adjust the data transmission time of the base device so that it can be in the optimal range of operational authorization access technology.
最後，請復參照圖1，在該可能干擾問題之示意圖情境中，若實施本發明授權輔助接入網路之資源調控方法，問題可如同後述的得到解決，其中，透過將儲存有設備可執行指令之非揮發性設備可讀媒體設置於第一小細胞B上，第一小細胞B可執行本發明授權輔助接入網路之資源調控方法。其中，在此使用場域中，當第一小細胞B收到使用者設備2回饋的即時資料接收正確率後，第一小細胞B若判定使用者設備2的資料傳輸正確率較以往為低，可能代表通道干擾較多，此時，其將Bias TX (t)設為+△ T ，藉此，第一小細胞B可增 加資料傳輸時間以避免傳輸的資料封包發生碰撞並流失；隨後，若第一小細胞B接收到使用者設備3回饋的即時資料接收正確率時，發現使用者設備3的傳輸資料正確率較高，則其可將Bias TX (t)設為-△ T ，以減少資料傳輸時間，即可避免傳輸資源的浪費，將能有效提升整體系統之效能。 Finally, please refer to FIG. 1. In the schematic scenario of the possible interference problem, if the resource control method for granting the auxiliary access network of the present invention is implemented, the problem can be solved as described later, wherein the device can be executed by storing the device. The commanded non-volatile device readable medium is disposed on the first small cell B, and the first small cell B can perform the resource control method of the authorized access network of the present invention. Wherein, in the field of use, when the first small cell B receives the real data receiving correct rate fed back by the user equipment 2, the first small cell B determines that the data transmission correct rate of the user equipment 2 is lower than before. It may represent more channel interference. At this time, it sets Bias TX ( t ) to +Δ T , whereby the first small cell B can increase the data transmission time to avoid collision and loss of the transmitted data packet; If the first small cell B receives instant feedback data user apparatus 3 receives the correct rate, the user device transmits the information found in the 3 high accuracy, it may be Bias TX (t) is set to - △ T, in order to By reducing the data transmission time, the waste of transmission resources can be avoided, and the overall system performance can be effectively improved.
