無線通訊系統及其中繼通訊裝置與無線通訊裝置 Wireless communication system, relay communication device and wireless communication device

本揭露是有關於一種無線通訊系統及其中繼通訊裝置與無線通訊裝置。 The disclosure relates to a wireless communication system, a relay communication device thereof and a wireless communication device.

目前無線通訊技術逐漸採用中繼轉傳(relay)技術來改善高傳輸速率的無線通訊涵蓋面積、群體移動性(group mobility)、基地台邊際傳輸量(cell-edge throughput)以及提供臨時的網路佈建方式。中繼通訊裝置(relay station)通常藉由無線傳輸方式連接至基地台，進而連接至無線接取網路(radio access network)。中繼通訊裝置所採用的連接方式可以分為：同頻段(inband)與異頻段(outband)。所述的同頻段連接方式即為在無線接取網路至中繼通訊裝置的鏈結(link)與無線接取網路至無線通訊裝置(或無線終端通訊裝置)的鏈結都使用相同的頻段或相同的載波。相反地，異頻段連接方式則為在無線接取網路至中繼通訊裝置的鏈結(link)，並沒有與無線接取網路直接至無線通訊裝置(或無線終端通訊裝置)的鏈結相同的頻段或相同的載波。 At present, wireless communication technology gradually adopts relay relay technology to improve high transmission rate wireless communication coverage area, group mobility, cell-edge throughput, and provision of temporary networks. Construction method. The relay station is usually connected to the base station by wireless transmission, and then connected to a radio access network. The connection methods used by the relay communication device can be divided into: inband and outband. The same-band connection mode is the same as the link between the wireless access network to the relay communication device link and the wireless access network to the wireless communication device (or the wireless terminal communication device). Band or the same carrier. Conversely, the inter-band connection method is a link between the wireless access network and the relay communication device, and there is no link between the wireless access network and the wireless communication device (or the wireless terminal communication device). The same frequency band or the same carrier.

另外，中繼通訊裝置的鏈結又可分為透明的(transparent)以及非透明的(non-transparent)。透明的中繼轉傳方式中，無線通訊裝置(或稱為UE)並不知道其與無線接取網路之間的溝通是否藉由中繼通訊裝置所進行的。相反的，非透明的中繼轉傳方式中，無線通訊裝置(UE)知道其 與無線接取網路之間的溝通是否藉由中繼通訊裝置所進行的。目前有IEEE 802.16j為主要採用中繼轉傳的無線通訊系統標準，但仍有其他通訊系統標準可使用中繼通訊裝置，例如：IEEE 802.16m標準與第三代通訊系統夥伴專案的先進長程演進(Third Generation Partnership Project Long Term Evolution Advanded，簡稱為3GPP LTE-Advanced)標準。 In addition, the links of the relay communication device can be further divided into transparent and non-transparent. In the transparent relay transfer mode, the wireless communication device (or UE) does not know whether the communication between the wireless communication device and the wireless access network is performed by the relay communication device. Conversely, in a non-transparent relay transfer mode, the wireless communication device (UE) knows its Whether communication with the wireless access network is performed by the relay communication device. Currently, IEEE 802.16j is a wireless communication system standard that mainly uses relay transfer, but there are still other communication system standards that can use relay communication devices, such as the advanced long-range evolution of the IEEE 802.16m standard and the third generation communication system partner project. (Third Generation Partnership Project Long Term Evolution Advanded, abbreviated as 3GPP LTE-Advanced) standard.

圖1A是一種習知的具有第一類中繼通訊裝置(Type 1 relay)的無線通訊系統10的示意圖。無線通訊系統10包括基地台101、第一類中繼通訊裝置102與無線通訊裝置103。第一類中繼通訊裝置102運作非透明的中繼轉傳方式，其控制本身所涵蓋的細胞範圍，還可控制一或多個細胞，並且具有一獨特的實體層細胞身份(physical layer cell identity)。從無線通訊裝置103看來，第一類中繼通訊裝置102與基地台101的無線資源管理(radio resource management，簡稱為RRM)方式是相同的。第3層中繼(layer 3 relay)通訊裝置，例如：實現自我回傳(self-backhauling)功能的第一類中繼通訊節點即類似於第一類中繼通訊裝置102。 1A is a schematic diagram of a conventional wireless communication system 10 having a first type of relay communication device (Type 1 relay). The wireless communication system 10 includes a base station 101, a first type of relay communication device 102, and a wireless communication device 103. The first type of relay communication device 102 operates a non-transparent relay transfer mode that controls the range of cells covered by itself, can also control one or more cells, and has a unique physical layer cell identity (physical layer cell identity). ). From the perspective of the wireless communication device 103, the first type of relay communication device 102 and the base station 101 have the same radio resource management (RRM) method. A layer 3 relay communication device, such as a first type of relay communication node that implements a self-backhauling function, is similar to the first type of relay communication device 102.

3GPP LTE-Advanced標準支援第一類中繼通訊裝置。例如，在3GPP第8版(Release 8)標準中，定義第一類中繼通訊裝置可傳送自己的一或多個同步通道(synchronization channel)與一或多個參考符號(reference symbols)。在單一細胞運作狀況下，無線通訊裝置103會 接收到由第一類中繼通訊裝置102發出的排程資訊與混合行自動重傳(HARQ)回授信號，並且無線通訊裝置103會傳送自己的控制信號資料或控制通道(例如：SR/CQI/ACK)回覆給第一類中繼通訊裝置102。在運作上，假若無線通訊裝置103是一個符合3GPP Release 8的使用者裝置(簡稱為UE)，第一類中繼通訊裝置102就像是一個符合3GPP Release 8的先進基地台(簡稱為eNodeB)。 The 3GPP LTE-Advanced standard supports the first type of relay communication device. For example, in the 3GPP Release 8 standard, a first type of relay communication device is defined to transmit one or more of its own synchronization channel and one or more reference symbols. In a single cell operating condition, the wireless communication device 103 will Receiving schedule information and hybrid line automatic retransmission (HARQ) feedback signals sent by the first type of relay communication device 102, and the wireless communication device 103 transmits its own control signal data or control channel (for example: SR/CQI) /ACK) Reply to the first type of relay communication device 102. In operation, if the wireless communication device 103 is a user device (referred to as UE) conforming to 3GPP Release 8, the first type of relay communication device 102 is like an advanced base station (referred to as eNodeB) conforming to 3GPP Release 8. .

圖1B是圖1A的無線通訊系統的下行鏈結從基地台101經過中繼裝置102到無線通訊裝置103傳送接收方式的示意圖。請同時參照圖1A與圖1B，在無線通訊系統10的下行鏈結(包括第一類中繼通訊裝置102下行至無線通訊裝置103，以及基地台101下行至第一類中繼通訊裝置102)，皆採用分時多工(time division multiplexing，簡稱為TDM)模式。圖1B將時間分成兩區，時間槽1與時間槽2，時間槽1為第一類中繼通訊裝置102的下行鏈結而時間槽2為無線通訊裝置103的下行鏈結。因為採用TDM模式來結合兩個鏈結於同一載波上或者第一類中繼通訊裝置102為同頻中繼通訊裝置，因此最高傳輸率由於分時多工的關係而降低。 FIG. 1B is a schematic diagram showing the manner in which the downlink link of the wireless communication system of FIG. 1A is transmitted from the base station 101 through the relay device 102 to the wireless communication device 103. Referring to FIG. 1A and FIG. 1B simultaneously, the downlink link of the wireless communication system 10 (including the first type of relay communication device 102 descending to the wireless communication device 103, and the base station 101 descending to the first type of relay communication device 102) Both use time division multiplexing (TDM) mode. 1B divides the time into two zones, time slot 1 and time slot 2, time slot 1 is the downlink link of the first type of relay communication device 102 and time slot 2 is the downlink link of the wireless communication device 103. Since the TDM mode is used to combine the two links on the same carrier or the first type of relay communication device 102 is a co-frequency relay communication device, the highest transmission rate is reduced due to the time division multiplexing relationship.

上行鏈結的部分也可能為第一類中繼通訊裝置102上行至基地台101的鏈結與無線通訊裝置103上行至第一類中繼通訊裝置102使用相同載波。如果是分頻雙工(frequency division duplex，簡稱為FDD)，上行鏈結亦會類似下行鏈結以TDM的方式分時使用此載波。如果是分時 雙工(time division duplex，簡稱為TDD)，此載波會再切割出兩個時槽給各自的上行鏈結。 The portion of the uplink link may also be that the first type of relay communication device 102 uplinks to the base station 101 and the wireless communication device 103 uplinks to the first type of relay communication device 102 using the same carrier. If it is frequency division duplex (FDD), the uplink link will use this carrier in a TDM manner similar to the downlink link. If it is time sharing For time division duplex (TDD), this carrier will cut two time slots for their respective uplinks.

圖2A是一種習知的具有第二類中繼通訊裝置(Type 2 relay)的無線通訊系統20的示意圖。無線通訊系統20包括基地台201、第二類中繼通訊裝置202與無線通訊裝置(或無線終端通訊裝置)203。第二類中繼通訊裝置202運作透明的與同頻段的中繼轉傳方式，其並不具獨特的實體層細胞身份(但仍可有一中繼身份)。從無線通訊裝置203看來，基地台201為無線通訊系統20的細胞施予者(donor cell)具有主控權，且具有至少部份無線資源管理(簡稱為RRM)並直接控制無線通訊裝置203。但仍有一部份無線資源管理是在第二類中繼通訊裝置202上運作的。例如，智慧型中繼(smart repeater)通訊裝置、解碼與轉傳(decode-and-forward)通訊裝置以及第2層中繼(layer 3 relay)通訊裝置即類似於第二類中繼通訊裝置202。 2A is a schematic diagram of a conventional wireless communication system 20 having a second type of relay communication device (Type 2 relay). The wireless communication system 20 includes a base station 201, a second type of relay communication device 202, and a wireless communication device (or wireless terminal communication device) 203. The second type of relay communication device 202 operates a transparent and same-band relay transfer mode, which does not have a unique physical layer cell identity (but can still have a relay identity). From the perspective of the wireless communication device 203, the base station 201 has master control for the donor cell of the wireless communication system 20, and has at least partial radio resource management (abbreviated as RRM) and directly controls the wireless communication device 203. . However, some of the radio resource management still operates on the second type of relay communication device 202. For example, a smart repeater communication device, a decode-and-forward communication device, and a layer 3 relay communication device are similar to the second type relay communication device 202. .

圖2B是圖2A的無線通訊系統的傳送接收方式的示意圖。請同時參照圖2A與圖2B，在無線通訊系統20的下行鏈結(包括第二類中繼通訊裝置202下行至無線通訊裝置203，以及基地台201下行至第二類中繼通訊裝置202，以及基地台201下行至無線通訊裝置203)，皆採用TDM模式。無線通訊裝置203的下行鏈結與第二類中繼通訊裝置202的下行鏈結由於共用一個載波。因此，無線通訊裝置203僅能使用時間槽2去接收，導致於無線通訊裝置203無法達到最高傳輸率。 2B is a schematic diagram of a transmission and reception mode of the wireless communication system of FIG. 2A. Please refer to FIG. 2A and FIG. 2B simultaneously, in the downlink link of the wireless communication system 20 (including the second type of relay communication device 202 descending to the wireless communication device 203, and the base station 201 descending to the second type of relay communication device 202, And the base station 201 goes down to the wireless communication device 203), and both adopt the TDM mode. The downlink link of the wireless communication device 203 and the downlink link of the second type of relay communication device 202 share one carrier. Therefore, the wireless communication device 203 can only receive using the time slot 2, resulting in the wireless communication device 203 failing to reach the highest transmission rate.

上行鏈結的部分也可能為第二類中繼通訊裝置202上行至基地台201的鏈結與無線通訊裝置203上行至第二類中繼通訊裝置202使用相同載波。如果是分頻雙工(frequency division duplex，簡稱為FDD)，上行鏈結亦會類似下行鏈結以TDM的方式分時使用此載波。如果是分時雙工(time division duplex，簡稱為TDD)，此載波會額外再被分出兩個時槽給上行鏈結。 The portion of the uplink link may also be the same carrier used by the second type of relay communication device 202 to uplink to the base station 201 and the wireless communication device 203 to the second type of relay communication device 202. If it is frequency division duplex (FDD), the uplink link will use this carrier in a TDM manner similar to the downlink link. In the case of time division duplex (TDD), this carrier will be additionally divided into two time slots for the uplink link.

3GPP LTE-Advanced標準支援第二類中繼通訊裝置。例如，在3GPP Release 8標準中，一個細胞中的基地台201至第二類中繼通訊裝置202的介面為Un介面，而第二類中繼通訊裝置202至無線通訊裝置203的介面為Uu介面，且Un介面與Uu介面為同頻段運作。在單一細胞運作狀況下，因為第二類中繼通訊裝置202沒有實體層細胞身份，不會產生新的細胞。對於無線通訊裝置203來說，其並不知道第二類中繼通訊裝置202運作在細胞中。然而，在3GPP Release 8標準中，第二類中繼通訊裝置202可傳送實體層下行共用通道(Physical Downlink Shared Channel，簡稱為PDSCH)，不過至少不會發送共同參考信號(Common Reference Signal，簡稱為CRS)與實體層下行控制通道(Physical Downlink Control Channel，簡稱為PDCCH)。 The 3GPP LTE-Advanced standard supports a second type of relay communication device. For example, in the 3GPP Release 8 standard, the interface of the base station 201 to the second type relay communication device 202 in one cell is the Un interface, and the interface of the second type relay communication device 202 to the wireless communication device 203 is the Uu interface. And the Un interface and the Uu interface operate in the same frequency band. In a single cell operating condition, since the second type of relay communication device 202 has no physical layer cell identity, no new cells are produced. For the wireless communication device 203, it is not known that the second type of relay communication device 202 operates in the cell. However, in the 3GPP Release 8 standard, the second type of relay communication device 202 can transmit a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH for short), but at least does not transmit a common reference signal (Common Reference Signal, referred to as The CRS is associated with a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short).

圖3是一種因中繼通訊裝置造成轉換時間間隔的示意圖。所述的轉換時間間隔，例如為：傳送轉換間隔(transmit transition gap，簡稱為TTG)以及接收轉換間隔(receive transition gap，簡稱為RTG)。由圖3可知，中繼通訊裝置在時間槽1接收資料或控制信號之後，並無法直接中繼轉傳此資料或控制信號至無線通訊裝置。在時間槽1與時間槽2之間，需要有一個接收至傳送的轉換時間間隔，這樣無線通訊裝置才能在時間槽2由中繼通訊裝置接收資料或控制信號。相類似地，在上行鏈結中也會有一個傳送至接收的轉換時間間隔。這些轉換時間間隔會造成無線資源的浪費。 Figure 3 is a schematic illustration of the transition time interval due to the relay communication device. The conversion time interval is, for example, a transmit transition gap (TTG) and a receive transition interval (receive). Transition gap, referred to as RTG). As can be seen from FIG. 3, after receiving the data or control signal in the time slot 1, the relay communication device cannot directly relay the data or control signal to the wireless communication device. Between time slot 1 and time slot 2, a receive time interval for reception to transmission is required so that the wireless communication device can receive data or control signals from the relay communication device in time slot 2. Similarly, there will also be a transition time interval for transmission to reception in the uplink link. These conversion time intervals can cause waste of wireless resources.

另外中繼通訊裝置在傳送流程與接收流程皆使用相同頻段，因此無線通訊裝置無法在傳送流程與接收流程使用全部的時間。由圖1B與圖2B的對應描述可知，在時間槽1的階段，無線通訊裝置並沒有接收任何資料或控制信號，因此使用者會覺得傳輸速率變慢。即使無線通訊裝置可以處理大的頻寬(例如：20MHz)，由於在部份時間內無法接收資料，無線通訊裝置將無法達到最高傳輸速率。進一步說明，由上述圖1A至圖2B的對應描述可知，無線通訊裝置的接收傳輸量(reception throughput)是受限於下行鏈結的載波數目與下行鏈結的運作時間。因此，如何降低使用中繼通訊裝置的無線通訊系統的轉換時間間隔與無線資源浪費，以提高運用中繼通訊方式的資料傳輸效率是一個重要的課題。 In addition, the relay communication device uses the same frequency band in both the transmission process and the receiving process, so the wireless communication device cannot use the entire time in the transmission process and the receiving process. As can be seen from the corresponding description of FIG. 1B and FIG. 2B, during the phase slot 1, the wireless communication device does not receive any data or control signals, so the user may feel that the transmission rate is slow. Even if the wireless communication device can handle a large bandwidth (for example, 20 MHz), the wireless communication device cannot reach the highest transmission rate because the data cannot be received for a part of the time. Further, it can be seen from the corresponding description of FIG. 1A to FIG. 2B that the reception throughput of the wireless communication device is limited by the number of carriers of the downlink node and the operation time of the downlink link. Therefore, how to reduce the conversion time interval and wireless resource waste of the wireless communication system using the relay communication device to improve the data transmission efficiency using the relay communication method is an important issue.

為讓本揭露之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。 The above described features and advantages of the present invention will be more apparent from the following description.

本揭露的多個示範實施例的基本原理主要將基地台到中繼通訊裝置的一下行鏈結與中繼通訊裝置到無線通訊裝置(UE)的另一下行鏈結分開到不同的載波，以致於中繼通訊裝置到無線通訊裝置(UE)的介面不與基地台到中繼通訊裝置的介面共用載波。如此一來，無線通訊裝置在部份狀況下可以完全使用中繼通訊裝置到無線通訊裝置的介面的載波，並同時可不需要傳送與接收流程之間的轉換時間間隔。另外，中繼通訊裝置到基地台的一上行鏈結，則與無線通訊裝置到中繼通訊裝置的另一上行鏈結共用相同的 載波或無線資源。根據上述對上行鏈結與下行鏈結不同的載波配置與運作方式，相對於圖1A與圖2A的傳統做法，如要避免降低下行最高傳輸速率與降低無線通訊裝置之使用者的經驗，則需要至少4個載波，本揭露的多個示範實施例可減少至僅須3個載波，並可有效地維持中繼通訊裝置與無線通訊裝置的最高傳輸速率。本揭露的多個示範實施例中的無線通訊裝置可以為例如：數位電視、數位機上盒、筆記型電腦、平板電腦、行動電話以及智慧型手機。 The basic principle of the exemplary embodiments of the present disclosure mainly separates the downlink link of the base station to the relay communication device and another downlink link of the relay communication device to the wireless communication device (UE) to different carriers, so that The interface between the relay communication device and the wireless communication device (UE) does not share a carrier with the interface of the base station to the relay communication device. In this way, the wireless communication device can completely use the carrier of the relay communication device to the interface of the wireless communication device under some conditions, and at the same time, the conversion time interval between the transmission and reception processes is not required.

圖4A是根據第一示範實施例所繪示一種具有第二類中繼通訊裝置的無線通訊系統40的示意圖。無線通訊系統40包括基地台401(例如為一eNodeB)、第二類中繼通訊裝置402與無線通訊裝置403。圖4B是圖4A的無線通訊系統40的傳送接收方式的載波與時序的示意圖。請同時參照圖4A與圖4B，在無線通訊系統40中，基地台401與第二類中繼通訊裝置402之間的傳輸方式採用FDD模式。此即，如圖4A所示，第二類中繼通訊裝置402與基地台401之間的下行鏈結使用第一頻段f1，而上行鏈結使用第三頻段f3。另外，第二類中繼通訊裝置402與無線通訊裝置403之間的傳輸方式也採用FDD模式。此即，如圖4A所示，第二類中繼通訊裝置402與無線通訊裝置403之間的下行鏈結使用第二頻段f2。此外，基地台401與無線通訊裝置403之間的傳輸方式也採用FDD模式。此即，如圖4A所示，基地台401與無線通訊裝置403之間的下行鏈結使用第二頻段f2，而上行鏈結使用第三頻段f3。 FIG. 4A is a schematic diagram of a wireless communication system 40 having a second type of relay communication device according to the first exemplary embodiment.
