Description

裝置間通訊的控制方法、中控裝置與行動裝置 Control method for communication between devices, central control device and mobile device

本揭露是有關於一種裝置間通訊的控制方法、中控裝置與行動裝置。 The disclosure relates to a method for controlling communication between devices, a central control device and a mobile device.

圖1是習知的長程演進技術(Long Term Evolution，LTE)頻分雙工(Frequency-Division Duplexing，FDD)系統其中的行動裝置上傳資料的示意圖。圖1繪示五個子訊框(subframe)，例如子訊框110。每個子訊框包括一個實體下行控制通道(Physical Downlink Control Channel，PDCCH)和一個共用通道，例如PDCCH 112以及共用通道114。共用通道包括一個實體下行共用通道(Physical Downlink Shared Channel，PDSCH)和一個實體上行共用通道(Physical Uplink Shared Channel，PUSCH)。在圖1的範例中，基地台(eNB)會在PDCCH傳送一個下行控制資訊(Downlink Control Information，DCI)120以告知行動裝置可上傳資料。DCI 120包括多個控制參數，例如可告知行動裝置使用哪一個無線資源和使用哪一種調變編碼方案(modulation coding scheme，MCS)來上傳資料。 FIG. 1 is a schematic diagram of a mobile device uploading data in a conventional Long Term Evolution (LTE) Frequency-Division Duplexing (FDD) system. FIG. 1 illustrates five sub-frames, such as sub-frame 110. Each subframe includes a physical downlink control channel (PDCCH) and a shared channel, such as a PDCCH 112 and a shared channel 114. The shared channel includes a physical downlink shared channel (PDSCH) and a physical uplink shared channel (PUSCH). In the example of FIG. 1, the base station (eNB) transmits a Downlink Control Information (DCI) 120 on the PDCCH to inform the mobile device that the data can be uploaded. DCI 120 includes A plurality of control parameters, for example, can inform the mobile device which radio resource to use and which modulation coding scheme (MCS) to use to upload the data.

每一個行動裝置在連接基地台時，基地台會分配一個基地台無線電網路暫時身分(Cell Radio Network Temporary Identifier，C-RNTI)給該行動裝置。一個PDCCH可能包含多個DCI，這些DCI是由基地台傳送給不同的行動裝置。基地台使用對應的行動裝置的C-RNTI擾亂(scramble)每一個DCI，行動裝置必須用自己的C-RNTI在PDCCH當中搜索屬於自己的DCI，搜索的方法是用行動裝置自己的C-RNTI去解碼每一個DCI，看解碼結果是否正確。結果正確的DCI就是基地台傳送給該行動裝置的DCI。 When each mobile device is connected to the base station, the base station allocates a Cell Radio Network Temporary Identifier (C-RNTI) to the mobile device. One PDCCH may contain multiple DCIs that are transmitted by the base station to different mobile devices. The base station scrambles each DCI using the C-RNTI of the corresponding mobile device, and the mobile device must search its own DCI in the PDCCH with its own C-RNTI. The search method is to use the mobile device's own C-RNTI. Decode each DCI and see if the decoding result is correct. The correct DCI is the DCI that the base station transmits to the mobile device.

由於行動裝置需要一段時間準備上傳的資料130，所以行動裝置在接收上述的DCI之後，必須經過LTE規範的標準處理延遲140之後，才能在PUSCH上傳資料130。例如頻分雙工(Frequency-Division Duplexing，FDD)系統的標準處理延遲是四個子訊框，如圖1的標準處理延遲140所示。 Since the mobile device needs to prepare the uploaded data 130 for a period of time, after receiving the DCI described above, the mobile device must pass the standard processing delay 140 of the LTE specification before uploading the data 130 on the PUSCH. For example, the standard processing delay of a Frequency-Division Duplexing (FDD) system is four sub-frames, as shown by the standard processing delay 140 of FIG.

圖2是習知的長程演進技術頻分雙工系統其中的行動裝置接收資料的示意圖。當基地台有資料230需要行動裝置接收時，會在PDCCH傳送一個DCI 220給行動裝置。DCI 220也包括多個控制參數，例如可告知行動裝置使用哪一個無線資源來接收資料230。由於行動裝置接收資料不需要準備時間，所以行動裝置可在同一個子訊框的PDSCH接收資料230。 2 is a schematic diagram of a mobile device receiving data in a conventional long-range evolution technology frequency division duplex system. When the base station has the data 230 requiring the mobile device to receive, a DCI 220 is transmitted to the mobile device on the PDCCH. The DCI 220 also includes a plurality of control parameters, such as which wireless resource the mobile device can use to receive the data 230. Since the mobile device does not need preparation time to receive the data, the mobile device can The PDSCH of the same subframe receives the data 230.

隨著行動寬頻應用成長以及行動裝置龐大的數據傳輸需求，無線電頻譜資源(以下簡稱為無線資源)的分配已日趨匱乏，從空間域增加可用頻寬的技術趨勢已逐漸成形。因此，第三代合作夥伴計畫(3rd Generation Partnership Project，3GPP)已開始研究在先進長程演進技術(Long Term Evolution-Advanced，LTE-A)裡支援裝置間通訊(device-to-device communication，D2D通訊)的可行性及制定系統需求。這種D2D通訊是在無線通訊系統的控制下，允許行動裝置之間在經由鄰近區域探索(proximity discovery)後，使用需執照頻帶(licensed band)或是結合異質型網路(heterogeneous network)使用免執照頻帶(unlicensed band)如無線區域網路(Wireless Local Area Networks，WLAN)以直接進行通訊的新型技術。它能夠增加系統頻譜效率，降低行動裝置發射功率，在一定程度上解決無線通訊系統頻譜資源匱乏的問題。除此之外，D2D通訊技術的實現也能滿足一些商務應用和災難救援上的鄰近區域通訊需求，例如商店的電子促銷傳單，以及區域警報與通話系統等等。 With the growth of mobile broadband applications and the huge data transmission requirements of mobile devices, the allocation of radio spectrum resources (hereinafter referred to as radio resources) has become increasingly scarce, and the trend of increasing the available bandwidth from the spatial domain has gradually taken shape. Therefore, the 3rd Generation Partnership Project (3GPP) has begun to study device-to-device communication (D2D) in Advanced Term Evolution-Advanced (LTE-A). Communication) and the development of system requirements. This D2D communication is under the control of the wireless communication system, allowing the mobile device to use the licensed band or the heterogeneous network after the proximity discovery through proximity discovery. Unlicensed bands, such as Wireless Local Area Networks (WLANs), are new technologies for direct communication. It can increase the spectrum efficiency of the system, reduce the transmission power of the mobile device, and solve the problem of lack of spectrum resources of the wireless communication system to a certain extent. In addition, the implementation of D2D communication technology can also meet the needs of some business applications and neighborhood communication on disaster relief, such as electronic promotional flyers in stores, as well as regional alarm and call systems.

D2D通訊的應用情境之一如圖3和圖4所示。圖3繪示行動裝置301與302、基地台310與320、以及核心網路330。行動裝置301與302之間原本透過網路端(基地台310、320以及核心網路330)所建立的上下行通訊連線進行通訊，如圖3所示，行動裝置301與302分別由基地台310與320控制。此時的上下行通訊的資料上傳與接收分別如圖1與圖2所示。隨著行動裝置301與302慢慢接近，行動裝置301與302進入同一基地台320的控制之下，如圖4所示，網路端將行動裝置301與302的通訊連線切換成D2D通訊以降低網路負載。然後，隨著行動裝置301與302慢慢的遠離，網路端判斷D2D通訊已無法維持後，又將通訊切換成圖3所示的一般上下行通訊。 One of the application scenarios of D2D communication is shown in Figures 3 and 4. 3 illustrates mobile devices 301 and 302, base stations 310 and 320, and core network 330. The mobile devices 301 and 302 communicate with each other through the uplink and downlink communication lines established by the network terminals (the base stations 310 and 320 and the core network 330). As shown in FIG. 3, the mobile devices 301 and 302 are respectively used by the base station. 310 and 320 controls. Up and down at this time The data upload and reception of the communication are shown in Figure 1 and Figure 2, respectively. As the mobile devices 301 and 302 slowly approach, the mobile devices 301 and 302 enter the control of the same base station 320. As shown in FIG. 4, the network end switches the communication connections of the mobile devices 301 and 302 to D2D communication. Reduce network load. Then, as the mobile devices 301 and 302 slowly move away, the network determines that the D2D communication cannot be maintained, and then switches the communication to the general uplink and downlink communication shown in FIG.

D2D通訊的一個重要的議題是：如何在傳統的上下行通訊連線切換成D2D通訊的情況下仍然維持行動裝置之間的通訊品質。在傳統的上下行通訊中，基地台與行動裝置必須先對它們之間的無線鏈路進行量測，包括通道品質(channel quality)、路徑損耗(pathloss)和提前時序(timing advance)等。通道品質的量測結果可以讓基地台在分配無線資源時最佳化系統的無線頻譜使用效率。路徑損耗的量測結果可以讓行動裝置計算該用多大的傳輸功率才能將資料傳送至基地台。提前時序的校正可以讓行動裝置所傳送的資料在經過傳播延遲(propagation delay)後仍能在基地台端於正確的時間點所接收。 An important topic of D2D communication is how to maintain the communication quality between mobile devices in the case of traditional uplink and downlink communication connections to D2D communication. In traditional uplink and downlink communications, base stations and mobile devices must first measure the wireless link between them, including channel quality, path loss, and timing advance. Channel quality measurements allow the base station to optimize the system's wireless spectrum usage efficiency when allocating radio resources. The measurement of the path loss allows the mobile device to calculate how much transmission power to use to transmit the data to the base station. The correction of the advance timing allows the data transmitted by the mobile device to be received at the correct time point on the base station after the propagation delay.

完成無線鏈路的量測後，基地台根據量測結果為行動裝置配置適當的無線資源，並透過PDCCH其中的DCI將無線資源配置的結果及一些控制參數傳送給行動裝置，就如圖1與圖2所示。由於通道的狀況可能因傳輸環境和行動裝置的移動速度等因素隨時間快速變化，所以LTE裡PDCCH的出現頻率高達每毫秒(1ms)一次，也就是說基地台可以透過PDCCH動態地且快速地配置資源給行動裝置以適應無線鏈路的狀況變化。為了維持行動裝置在D2D通訊下的通訊品質和降低通訊連線切換的複雜度及成本，D2D通訊也需要對應的控制方法，也就是以下的本揭露實施例所提供的D2D通訊的控制方法。 After the measurement of the wireless link is completed, the base station configures the appropriate radio resource for the mobile device according to the measurement result, and transmits the radio resource through the DCI of the PDCCH. The result of the configuration and some control parameters are transmitted to the mobile device as shown in Figures 1 and 2. Since the condition of the channel may change rapidly with time due to factors such as the transmission environment and the moving speed of the mobile device, the frequency of occurrence of the PDCCH in LTE is as high as once every millisecond (1 ms), that is, the base station can be dynamically and quickly configured through the PDCCH. Resources are provided to mobile devices to accommodate changes in the status of the wireless link. In order to maintain the communication quality of the mobile device under D2D communication and reduce the complexity and cost of the communication connection switching, the D2D communication also needs a corresponding control method, that is, the D2D communication control method provided by the following embodiments.

First, in step 531, the central control device 500 assigns a measurement information to the mobile devices 510 and 520. The mobile devices 510 and 520 receive the above measurement information. The central control device 500 can allocate the above measurement information by using a Radio Resource Control (RRC) message. The measurement information may include a reference signal, such as a Sounding Reference Signal (SRS) defined by LTE.

上述量測資訊也可包括一個D2D識別碼，行動裝置510和520可用此D2D識別碼搜索中控裝置500為行動裝置510和520之間的D2D通訊所傳送的資源配置訊息。上述的資源配置訊息可以是LTE其中的DCI。 The measurement information may also include a D2D identification code, and the mobile devices 510 and 520 may use the D2D identification code to search the resource configuration message transmitted by the central control device 500 for D2D communication between the mobile devices 510 and 520. The resource configuration message described above may be a DCI in LTE.

上述量測資訊也可包括上述參考訊號的傳輸功率。或者，此傳輸功率可以不包括在上述量測資訊中，而是預設於行動裝置510和520之中1。 The above measurement information may also include the transmission power of the above reference signal. Alternatively, the transmission power may not be included in the above measurement information, but is preset to 1 among the mobile devices 510 and 520.

在步驟532，行動裝置510根據上述量測資訊傳送上述參考訊號給行動裝置520。更詳細的說，行動裝置510以上述的傳輸功率傳送上述參考訊號給行動裝置520。同樣在步驟532，行動裝置520根據上述量測資訊接收從行動裝置510傳來的參考訊號，並根據接收的參考訊號決定上述量測程序的量測結果。 At step 532, the mobile device 510 transmits the reference signal to the mobile device 520 according to the measurement information. In more detail, the mobile device 510 transmits the reference signal to the mobile device 520 at the transmission power described above. Also in step 532, the mobile device 520 receives the reference signal transmitted from the mobile device 510 according to the measurement information, and determines the measurement result of the measurement program according to the received reference signal.

上述量測結果可包括行動裝置510和520之間的通道品質、路徑損耗、以及提前時序。行動裝置520可比對接收的參考訊號和中控裝置500分配的量測資訊其中的參考訊號以量測通道品質。行動裝置520可比對接收的參考訊號的功率和上述量測資訊其中的或預設的傳輸功率以量測路徑損耗。至於上述提前時序如何量測，可參照LTE其中的基地台與行動裝置之間的提前時序的量測。 The above measurement results may include channel quality, path loss, and advance timing between the mobile devices 510 and 520. The mobile device 520 can compare the reference signal received by the received reference signal and the measurement information allocated by the central control device 500 to measure the channel quality. The mobile device 520 can measure the path loss by comparing the power of the received reference signal with the above-mentioned measurement information or the preset transmission power. As for how to measure the above advance timing, refer to the advance timing between the base station and the mobile device in LTE. Measurement.

在步驟533，行動裝置520回報上述量測結果給中控裝置500，中控裝置500接收行動裝置520回報的量測結果。行動裝置520可用RRC訊息回報上述量測結果。 At step 533, the mobile device 520 reports the above measurement result to the central control device 500, and the central control device 500 receives the measurement result reported by the mobile device 520. The mobile device 520 can report the above measurement result by using the RRC message.

在步驟534，中控裝置500傳送一個RRC訊息以告知行動裝置510與520中控裝置500即將傳送資源配置訊息，行動裝置510與520接收上述的RRC訊息。上述的資源配置訊息可以是LTE其中的DCI。上述的D2D識別碼可藉由步驟531或步驟534的RRC訊息傳送給行動裝置510和520。 In step 534, the central control device 500 transmits an RRC message to inform the mobile devices 510 and 520 that the central control device 500 is about to transmit a resource configuration message, and the mobile devices 510 and 520 receive the RRC message. The resource configuration message described above may be a DCI in LTE. The D2D identification code described above may be transmitted to the mobile devices 510 and 520 by the RRC message of step 531 or step 534.

在中控裝置500傳送資源配置訊息之前，中控裝置500必須先建立行動裝置510和520之間的D2D連線。而D2D連線的建立時點是視行動裝置520在步驟533回報的量測結果與中控裝置500的資源排程(scheduling)而定。步驟534的用意之一是在建立D2D連線需時較長時避免行動裝置510和520徒勞地搜索資源配置訊息。如果建立D2D連線需時較短，而且步驟531的量測資訊已包括上述的D2D識別碼，則可以省略步驟534。 Before the central control device 500 transmits the resource configuration message, the central control device 500 must first establish a D2D connection between the mobile devices 510 and 520. The establishment time of the D2D connection is determined by the measurement result reported by the mobile device 520 in step 533 and the resource scheduling of the central control device 500. One of the intents of step 534 is to prevent mobile devices 510 and 520 from vainly searching for resource configuration messages when it takes longer to establish a D2D connection. If the D2D connection is set to take a shorter time and the measurement information of step 531 already includes the D2D identification code described above, step 534 may be omitted.

在步驟535，中控裝置500為行動裝置510和520之間的D2D通訊配置無線資源，然後透過一個控制通道使用上述的D2D識別碼傳送一個資源配置訊息，行動裝置510和520使用上述D2D識別碼在上述控制通道搜索上述資源配置訊息，行動裝置510根據上述資源配置訊息傳送資料給行動裝置520以進行D2D通訊。中控裝置500根據行動裝置520在步驟533回報的量測結果決定上述資源配置訊息所配置的無線資源。上述控制通道可以是LTE其中的PDCCH，上述資源配置訊息可以是LTE其中的DCI。 In step 535, the central control device 500 configures radio resources for D2D communication between the mobile devices 510 and 520, and then transmits a resource configuration message using the D2D identification code through a control channel, and the mobile devices 510 and 520 use the D2D identification code. Searching for the resource configuration message in the control channel, the mobile device 510 transmits the data to the mobile device 520 according to the resource configuration message for D2D communication. The central control device 500 determines according to the measurement result reported by the mobile device 520 at step 533. The radio resource configured by the above resource configuration message. The foregoing control channel may be a PDCCH in the LTE, and the resource configuration message may be a DCI in the LTE.

圖7是本揭露的一實施例的步驟535的示意圖，其中的傳送端就是行動裝置510，接收端就是行動裝置520。圖7繪示五個子訊框，例如子訊框710。在傳統的上下行通訊中，基地台用兩個DCI以分別傳送資料的傳送端與接收端的控制參數；而在本實施例中，中控裝置500僅使用一個資源配置訊息720以傳送傳送端510和接收端520的控制參數。 FIG. 7 is a schematic diagram of step 535 of an embodiment of the present disclosure, wherein the transmitting end is the mobile device 510 and the receiving end is the mobile device 520. FIG. 7 illustrates five sub-frames, such as subframe 710. In the conventional uplink and downlink communication, the base station uses two DCIs to respectively transmit the control parameters of the transmitting end and the receiving end of the data; in the embodiment, the central control device 500 uses only one resource configuration message 720 to transmit the transmitting end 510. And the control parameters of the receiving end 520.

如上所述，行動裝置510和520可以從步驟531或534的RRC訊息中取得D2D識別碼。此D2D識別碼是由中控裝置500決定。此D2D識別碼可以是行動裝置510或520的識別碼，或是另一個特地為此D2D通訊而配置的識別碼。上述的行動裝置510的識別碼、行動裝置520的識別碼、以及D2D識別碼都可以是LTE其中的C-RNTI。就像圖1和圖2的行動裝置使用C-RNTI在PDCCH當中搜索DCI，行動裝置510和520可用上述D2D識別碼在控制通道712搜索中控裝置500傳送的資源配置訊息720。 As described above, mobile devices 510 and 520 can retrieve the D2D identification code from the RRC message of step 531 or 534. This D2D identification code is determined by the central control unit 500. The D2D identification code may be an identification code of the mobile device 510 or 520 or another identification code specifically configured for this D2D communication. The identification code of the mobile device 510, the identification code of the mobile device 520, and the D2D identification code may all be C-RNTIs in LTE. Just as the mobile devices of FIGS. 1 and 2 use the C-RNTI to search for DCI among the PDCCHs, the mobile devices 510 and 520 can search the control channel 712 for the resource configuration message 720 transmitted by the central control device 500 using the D2D identification code described above.

行動裝置510和520除了和對方進行D2D通訊，也可能和基地台500進行一般上下行通訊。在此情況下，行動裝置510和520必須在控制通道搜索D2D通訊的資源配置訊息以及一般上下行通訊的資源配置訊息。 The mobile devices 510 and 520 may perform general uplink and downlink communication with the base station 500 in addition to D2D communication with the other party. In this case, the mobile devices 510 and 520 must search for the resource configuration message of the D2D communication and the resource configuration message of the general uplink and downlink communication in the control channel.

如果上述的D2D識別碼就是行動裝置510的識別碼，則行動裝置510只需要用自己的識別碼搜尋資源配置訊息，而行動裝置520則需要用自己的識別碼和D2D識別碼搜尋資源配置訊息。為了讓行動裝置510和520分辨D2D通訊和一般上下行通訊的資源配置訊息，中控裝置500傳送的資源配置訊息可包括一個指示符(indicator)以指出該資源配置訊息是針對D2D通訊的資源配置或是一般上下行通訊的資源配置。 If the D2D identification code is the identification code of the mobile device 510, the mobile device 510 only needs to search for the resource configuration message with its own identification code, and the action The device 520 needs to search for the resource configuration message with its own identification code and D2D identification code. In order for the mobile devices 510 and 520 to distinguish the resource configuration information of the D2D communication and the general uplink and downlink communication, the resource configuration message transmitted by the central control device 500 may include an indicator to indicate that the resource configuration message is a resource configuration for the D2D communication. Or the resource configuration of general uplink and downlink communication.

如果上述的D2D識別碼就是行動裝置520的識別碼，則行動裝置510需要用自己的識別碼和D2D識別碼搜尋資源配置訊息，而行動裝置520只需要用自己的識別碼搜尋資源配置訊息。為了讓行動裝置510和520分辨D2D通訊和一般上下行通訊的資源配置訊息，中控裝置500傳送的資源配置訊息同樣可包括上述的指示符以指出該資源配置訊息是針對D2D通訊的資源配置或是一般上下行通訊的資源配置。 If the D2D identification code is the identification code of the mobile device 520, the mobile device 510 needs to search for the resource configuration message with its own identification code and D2D identification code, and the mobile device 520 only needs to search for the resource configuration message with its own identification code. In order for the mobile devices 510 and 520 to distinguish the resource configuration information of the D2D communication and the general uplink and downlink communication, the resource configuration message transmitted by the central control device 500 may also include the above indicator to indicate that the resource configuration message is a resource configuration for D2D communication or It is the resource configuration of general uplink and downlink communication.

如果上述的D2D識別碼是另一個特別配置的識別碼，則行動裝置510需要用自己的識別碼和D2D識別碼搜尋資源配置訊息，行動裝置520同樣需要用自己的識別碼和D2D識別碼搜尋資源配置訊息。不過在此情況中控裝置500傳送的資源配置訊息不需要包括上述的指示符。 If the D2D identification code is another specially configured identification code, the mobile device 510 needs to search for the resource configuration message with its own identification code and D2D identification code, and the mobile device 520 also needs to search for resources with its own identification code and D2D identification code. Configure the message. However, in this case, the resource configuration message transmitted by the central control device 500 does not need to include the above indicator.

如圖7所示，搜索到D2D通訊的資源配置訊息720之後，行動裝置510根據資源配置訊息720直接傳送資料730給行動裝置520，而不經由中控裝置500。資源配置訊息720可包括多個控制參數，例如可告知行動裝置510使用哪一個無線資源和使用哪一種調變編碼方案(MCS)來傳送資料730。上述控制參數也可包括行動裝置520在步驟532量測的提前時序與路徑損耗。行動裝置510可根據以上控制參數直接傳送資料730給行動裝置520。行動裝置510可根據上述路徑損耗計算傳送資料730所需的傳輸功率。 As shown in FIG. 7, after searching for the resource configuration message 720 of the D2D communication, the mobile device 510 directly transmits the data 730 to the mobile device 520 according to the resource configuration message 720 without passing through the central control device 500. The resource configuration message 720 can include a plurality of control parameters, such as which wireless resource can be communicated to the mobile device 510 and which modulation coding scheme (MCS) is used to transmit the data 730. The above control parameters may also include The advance timing and path loss measured by the mobile device 520 at step 532. The mobile device 510 can directly transmit the data 730 to the mobile device 520 according to the above control parameters. The mobile device 510 can calculate the transmission power required to transmit the data 730 based on the path loss described above.

或者，資源配置訊息720可以不包括上述路徑損耗而直接包括上述傳輸功率。在此情況的傳輸功率是由中控裝置500根據路徑損耗計算產生。上述的路徑損耗與傳輸功率可合稱為功率參數。 Alternatively, the resource configuration message 720 may directly include the above transmission power without including the path loss described above. The transmission power in this case is generated by the central control unit 500 based on the path loss calculation. The above path loss and transmission power can be collectively referred to as a power parameter.

行動裝置520可根據資源配置訊息720其中的上述控制參數接收直接從行動裝置510傳來的資料730。圖7的實施例是在LTE系統中操作，所以行動裝置520在發現資源配置訊息720是指示進行D2D通訊時，必須先等待行動裝置510的標準處理延遲740，然後才根據資源配置訊息720接收直接從行動裝置510傳來的資料730。 Mobile device 520 can receive material 730 directly from mobile device 510 based on the aforementioned control parameters of resource configuration message 720. The embodiment of FIG. 7 is operated in the LTE system, so the mobile device 520 must wait for the standard processing delay 740 of the mobile device 510 before the discovery resource configuration message 720 indicates that the D2D communication is to be performed, and then receive the direct response according to the resource configuration message 720. Data 730 from the mobile device 510.

如果上述的D2D識別碼是行動裝置510或520的識別碼，除了在資源配置訊息包括指示符之外，也可以採用隱含的指示方法。例如可事前規定D2D通訊的資源配置訊息所配置的無線資源只能是上行子訊框(uplink subframe)或上行頻帶裡的無線資源。如此，當資源配置訊息是要求行動裝置520在下行子訊框或下行頻帶的無線資源接收資料，表示該資源配置訊息是指示行動裝置520進行一般下行通訊，因此行動裝置520依照指示進行一般下行通訊。當資源配置訊息是要求行動裝置520在上行子訊框或上行頻帶的無線資源接收資料，表示該資源配置訊息是指示行動裝置520進行D2D通訊，因此行動裝置520依照指示進行D2D通訊。 If the D2D identification code described above is the identification code of the mobile device 510 or 520, an implicit indication method may be employed in addition to the resource configuration message including the indicator. For example, the radio resource configured by the resource configuration message of the D2D communication may be the uplink subframe or the radio resource in the uplink frequency band. In this manner, when the resource configuration message is required to receive data from the mobile device in the downlink subframe or the downlink frequency band, indicating that the resource configuration message is to instruct the mobile device 520 to perform general downlink communication, the mobile device 520 performs general downlink communication according to the indication. . When the resource configuration message is that the mobile device 520 requests the mobile device to receive data in the uplink subframe or the uplink frequency band, indicating that the resource configuration message is an indication line. The mobile device 520 performs D2D communication, so the mobile device 520 performs D2D communication in accordance with the instruction.

比對圖7與圖2可知，行動裝置520在進行D2D通訊時需要等待行動裝置510的標準處理延遲740以接收資料，在進行一般上下行通訊時則不需等待。所以圖7的實施例中的行動裝置520需要分辨資源配置訊息是針對D2D通訊還是針對一般上下行通訊。而比對圖7與圖1可知，行動裝置510在進行D2D通訊和進行一般上下行通訊時都需要等待標準處理延遲740以傳送資料。所以圖7的實施例中的行動裝置510其實不需要分辨D2D通訊和一般上下行通訊的資源配置訊息。 Comparing FIG. 7 with FIG. 2, the mobile device 520 needs to wait for the standard processing delay 740 of the mobile device 510 to receive data when performing D2D communication, and does not need to wait for general uplink and downlink communication. Therefore, the mobile device 520 in the embodiment of FIG. 7 needs to distinguish whether the resource configuration message is for D2D communication or for general uplink and downlink communication. As can be seen from FIG. 7 and FIG. 1, the mobile device 510 needs to wait for the standard processing delay 740 to transmit data when performing D2D communication and performing general uplink and downlink communication. Therefore, the mobile device 510 in the embodiment of FIG. 7 does not need to distinguish the resource configuration information of the D2D communication and the general uplink and downlink communication.

圖8是依照本揭露的另一實施例的步驟535的示意圖。圖8繪示五個子訊框，例如子訊框810。本實施例的中控裝置500先使用行動裝置510的識別碼傳送資源配置訊息821給行動裝置510。經過行動裝置510的標準處理延遲840之後，再使用行動裝置520的識別碼傳送資源配置訊息822給行動裝置520。在最後一個子訊框，行動裝置510直接傳送資料830給行動裝置520。在本實施例中，不需要為D2D通訊特別配置額外的識別碼，不需要在資源配置訊息加入指示符，行動裝置510和520都不需要分辨資源配置訊息是針對D2D通訊還是針對一般上下行通訊。 FIG. 8 is a schematic diagram of step 535 in accordance with another embodiment of the present disclosure. FIG. 8 illustrates five sub-frames, such as subframe 810. The central control device 500 of the present embodiment first transmits the resource configuration message 821 to the mobile device 510 using the identification code of the mobile device 510. After the standard processing delay 840 of the mobile device 510, the resource configuration message 822 is transmitted to the mobile device 520 using the identification code of the mobile device 520. In the last subframe, the mobile device 510 transmits the data 830 directly to the mobile device 520. In this embodiment, there is no need to specially configure an additional identifier for the D2D communication, and there is no need to add an indicator to the resource configuration message, and the mobile devices 510 and 520 do not need to distinguish whether the resource configuration message is for D2D communication or for general uplink and downlink communication. .

綜上所述，本揭露提供一種D2D通訊的控制方法、中控裝置與行動裝置，可適應無線鏈路的狀況而動態控制D2D通訊，以使無線資源的使用最佳化。本揭露的實施例可以只用行動裝置本身的識別碼並且只使用一個資源配置訊息做D2D通訊的資源給予(resource grant)，可節省識別碼的資源以及控制通道的無線資源。 In summary, the disclosure provides a D2D communication control method, a central control device and a mobile device, which can dynamically control D2D communication according to the condition of the wireless link, so as to optimize the use of the wireless resource. Embodiments of the present disclosure may use only mobile devices The own identification code and only one resource configuration message is used for resource grant of D2D communication, which can save the resources of the identification code and the radio resources of the control channel.

雖然本揭露已以實施例揭露如上，然其並非用以限定本揭露，任何所屬技術領域中具有通常知識者，在不脫離本揭露的精神和範圍內，當可作些許的更動與潤飾，故本揭露的保護範圍當視後附的申請專利範圍所界定者為準。 The present disclosure has been disclosed in the above embodiments, but it is not intended to limit the disclosure, and any person skilled in the art can make some changes and refinements without departing from the spirit and scope of the disclosure.
