用於在一上鏈上傳輸短長度的資料。更細部而言，RACH 係在當該UE取得初始上鏈同步化時使用。RACH係在當 該UE於一開始開機或由一長時間待機模式切換到一啟用 模式時使用，使得該上鏈同步化再次設定，並可在未建立 時間同步化或頻率同步化之下使用。該RACH基本上支援 多個使用者。每個UE在當存取該RACH時傳輸一特定前 言序列，該節點B識別該前言序列，並傳輸一信號到一下 鏈，且該UE使用該資訊更新其本身的時間同步化資訊。 此時，如果頻率同步化資訊一起被傳輸，則該頻率同步化 資訊可用於該UE的資訊中。 該RACH為該輸送通道，其對映到該實體隨機存取通 道（PRACH，Physical Random Access Channel)。 第3圖所示為一習用PRACH傳輸。 如第3圖所示’該PRACH區分成一前言部份及一訊 息部份。該刖言部份貫施一功率提升功能，用於適當地控 制用於訊息傳輸之傳輸功率，以及一用於避免數個UE之 間的碰撞之功能。該訊息部份實施用於傳輸由該MAC傳 輸到該實體通道之一 MAC協定資料單元（以下簡稱為 PDU，Protocol Data Unit)之功能。 7 200836503 當該UE的MAC指示一 praCH傳輸到該UE的實體 層時，該UE的實體層先選擇一存取槽與一簽章，並在該 PRACH上傳輸該前言到一上鏈。該前言於長度1331118之 存取槽持續時間内傳輸，且一簽章由在該存取槽之第一特 定長度内16個簽章中選出並傳輸。當該υΕ傳輸該前言 時，該節點B經由為一下鏈實體通道之一取得指標通道 (AICH，Acquisition Indicator* Channel)傳輸一回應信號。 回應於該前言，該AICH傳輪該簽章，其由該前言選出， 並係在對應於用於傳輸該前言之存取槽的該存取槽之第一 特定長度内。此時，該節點B經由該a IC H傳輸的該簽章 傳輸一確認（ACK)回應或一未確認（NACK)回應到該UE。 當該UE接收該ACK回應時，該UE使用對應於所傳 輸的簽章的一正交可變展開係數（〇VSF，〇rth〇g〇nal Variable Spreading Factor)傳輸長度為 1〇 ms 或 20 ms 之訊 息部份。 當該UE接收該NACK回應時，該ue的MAC在某一 特定時段之後指示一 PRACH重新傳輸到該UE的實體層。 相反地，如果該UE並未接收到對應於所傳輸的前言之 AICH，則該UE在一預定存取槽之後利用高於先前前言之 功率傳輸一新前言。 第4圖所示為一習用下鏈實體通道之一 AICH之範例 性結構。Used to transmit short lengths of data on an upper chain. In more detail, the RACH is used when the UE obtains initial uplink synchronization. The RACH is used when the UE is initially turned on or switched from a long standby mode to an enabled mode, so that the uplink synchronization is set again and can be used without establishing time synchronization or frequency synchronization. The RACH basically supports multiple users. Each UE transmits a particular preamble sequence when accessing the RACH, the Node B identifies the preamble sequence, and transmits a signal to the next chain, and the UE uses the information to update its own time synchronization information. At this time, if the frequency synchronization information is transmitted together, the frequency synchronization information can be used in the information of the UE. The RACH is the transport channel, which is mapped to the physical random access channel (PRACH). Figure 3 shows a conventional PRACH transmission. As shown in Figure 3, the PRACH is divided into a preamble and a message section. The rumor partially implements a power boost function for appropriately controlling the transmission power for message transmission and a function for avoiding collision between several UEs. The message is implemented in part for transmitting a MAC protocol data unit (hereinafter referred to as a PDU, Protocol Data Unit) transmitted by the MAC to the physical channel. 7 200836503 When the MAC of the UE indicates that a praCH is transmitted to the physical layer of the UE, the physical layer of the UE first selects an access slot and a signature, and transmits the preamble to an uplink on the PRACH. The preamble is transmitted for the duration of the access slot of length 1331118, and a signature is selected and transmitted by 16 signatures within the first specific length of the access slot. When the υΕ transmits the preamble, the Node B transmits a response signal via an AICH (Acquisition Indicator* Channel) for one of the linked physical channels. In response to the preamble, the AICH passes the signature, which is selected by the preamble and is within a first particular length of the access slot corresponding to the access slot for transmitting the preamble. At this time, the Node B transmits an acknowledgement (ACK) response or an unacknowledged (NACK) response to the UE via the signature transmitted by the a IC H. When the UE receives the ACK response, the UE transmits a length of 1 〇 or 20 ms using an orthogonal variable expansion coefficient (〇VSF, 〇rth〇g〇nal Variable Spreading Factor) corresponding to the transmitted signature. The message part. When the UE receives the NACK response, the MAC of the ue indicates that a PRACH is retransmitted to the physical layer of the UE after a certain period of time. Conversely, if the UE does not receive an AICH corresponding to the transmitted preamble, the UE transmits a new preamble after a predetermined access slot with a higher power than the previous preamble. Figure 4 shows an exemplary structure of AICH, one of the traditional downlink physical channels.

在本發明一具體實施例中，為了有效率地使用一無線 電資源，——無線電使用者設備（UE)包括該下鏈通道的品質 測量資訊於傳輸到一上鏈的該RACH訊息之第二層L2的 標頭中。一無線電網路使用包括在第二層 L2之標頭中的 品質測量資訊控制該 RACH訊息的一回應訊息之傳輸功 率，並傳輸該回應訊息到該UE。 在本發明另一具體實施例中，為了有效率地使用一無 線電資源，UE包括該下鏈通道的品質測量資訊於鄰接傳輸 到一上鏈的該RACH訊息之第二層L2的標頭之有效負載 中。該無線電網路使用包括在該有效負載中的品質測量資 訊控制該RACH訊息的一回應訊息之傳輸功率，並傳輸該 回應訊息到該UE。在此例中，該無線電UE可用一負載方 式包括該品質測量資訊於一 L2-PDU中，並傳輸該RACH 訊息到該無線電網路。 此具體實施例將參照第6圖說明如下。 14 200836503 UE 5 10可在一 RACH前言傳輸步驟及回應該RAC Η前 言的一步驟之後傳輸該RACH訊息，如第6圖所示。因此， UE 510先傳輸該RAch的前言到節點B 520(61 0)。 接著，當該前言被正確地接收時，節點B 520傳輸該 RACH前言之ACK回應到UE 510(620)。相反地，當該前 言並未被接收或未正確地接收時，節點B 520傳輸該RACH 前言之一 NACK回應到UE 5 1 0 (620)。In an embodiment of the present invention, in order to efficiently use a radio resource, a radio user equipment (UE) includes quality measurement information of the downlink channel on a second layer of the RACH message transmitted to an uplink. In the header of L2. A radio network controls the transmission power of a response message of the RACH message using quality measurement information included in the header of the second layer L2, and transmits the response message to the UE. In another embodiment of the present invention, in order to efficiently use a radio resource, the UE includes the quality measurement information of the downlink channel validly adjacent to the header of the second layer L2 of the RACH message transmitted to an uplink. In the load. The radio network controls the transmission power of a response message of the RACH message using quality measurement information included in the payload, and transmits the response message to the UE. In this example, the radio UE may include the quality measurement information in an L2-PDU in a load mode and transmit the RACH message to the radio network. This specific embodiment will be explained below with reference to Fig. 6. 14 200836503 UE 5 10 may transmit the RACH message after a RACH preamble transmission step and a step back to the RAC Η preamble, as shown in FIG. Therefore, the UE 510 first transmits the preamble of the RAch to the Node B 520 (61 0). Next, when the preamble is correctly received, Node B 520 transmits an ACK response to the RACH preamble to UE 510 (620). Conversely, when the preamble is not received or not received correctly, Node B 520 transmits one of the RACH preambles to the UE 5 1 0 (620).
接著，U E 5 1 0傳輸節點B 5 2 0之下鏈通道的品質測量 資訊到節點B 520(630)，例如該RACH訊息包括一通道品 質指示（CQI， Channel Quality Indication)。此時，該 RACH 訊息可包括至少一 L2-PDU。如果L2-PDU包括該品質測量 資訊，則該L2-PDU之標頭，也就是L2標頭，可通知該品 質測量資訊是否包括在L2標頭中或L2-PDU包括該L2之 標頭。例如，L2標頭可為設置該MAC PDU之一 MAC標 頭。更詳細而言，指示CQI是否包括在該MAC PDU中的 資訊可以儲存在該MAC標頭的一目標通道種類攔位（TCTF) 中。 該MAC PDU可包括傳輸到一共用控制通道（CCCH)、 一專屬控制通道（DCCH)或一專屬交通通道（DTCH)的一 RRC訊息，其所有皆為該等邏輯通道。 當該UE被開機然後先存取一新單元時，該UE建立下 鏈同步化及接收要被存取之單元的系統資訊。在接收該系 統資訊之後，該UE傳輸一存取請求訊息做RRC連接。但 是，由於該UE並未與一目前網路建立時間同步化，且並 15Next, U E 5 1 0 transmits the quality measurement information of the link channel below the node B 5 2 0 to the Node B 520 (630), for example, the RACH message includes a Channel Quality Indication (CQI). At this time, the RACH message may include at least one L2-PDU. If the L2-PDU includes the quality measurement information, the header of the L2-PDU, that is, the L2 header, can inform whether the quality measurement information is included in the L2 header or the L2-PDU includes the header of the L2. For example, the L2 header can be a MAC header that sets one of the MAC PDUs. In more detail, information indicating whether the CQI is included in the MAC PDU may be stored in a target channel type intercept (TCTF) of the MAC header. The MAC PDU may include an RRC message transmitted to a Common Control Channel (CCCH), a Dedicated Control Channel (DCCH), or a Dedicated Traffic Channel (DTCH), all of which are such logical channels. When the UE is powered on and then accesses a new unit, the UE establishes downlink synchronization and receives system information of the unit to be accessed. After receiving the system information, the UE transmits an access request message for an RRC connection. However, since the UE is not synchronized with a current network setup time, and
200836503 未保證一上鏈無線電資源，因此可使用該RAC Η。 說，該UE請求該無線電資源，該資源用於使用該 來傳輸連接請求訊息到該網路。接收該無線電資源 之節點Β配置一適當的無線電資源予該UE。然後 可經由該無線電資源傳輸一 RRC連接請求訊息到安 在該UE做RRC連接於該網路的狀態中，為 連接模式的UE可使用該RACH。在此例中，該UE 據該網路的無線電資源排程配置的無線電資源，並 配置的無線電資源傳輸資料到該網路。但是，如果 輸的資料不再留在該UE的緩衝器中，則該網路不 該上鏈無線電資源予該UE。這是因為配置該上鏈無 源予不具有要傳輸的資料之UE並沒有效率。如果 發生在不具有該無線電資源的 UE之缓衝器中，貝 可使用該 RACH，因為該上鏈無線電資源並未配 UE。也就是說，該UE可進行請求該無線電資源， 用該RACH傳輸資料到該網路所需要。 也就是說，一些RRC訊息，例如一 RRC連接 息、一單元更新訊息及一 URA更新訊息，其亦可 RACH 傳輸。此時，該 CCCH、DCCH 及 DTCH，士 等邏輯通道，其可對映到為該輸送通道之RACH。 該下鏈通道之品質測量資訊可被包括在L2 i 例如MAC標頭，或可包括在一 MAC有效負載的-份中，或是以一負載方式包括在鄰接於L2標頭的 效負載之一後端部份。 也就是 RACH 的請求 ，該UE 餐網路。 該 RRC 接收根 經由所 要被傳 再配置 線電資 新資料 丨J該 UE 置給該 其為使 請求訊 經由該 皆為該 :頭中， 前端部 MAC有 16 200836503 接著，節點B 5 2 0使用該下鏈通道之品質測量資 行可適化調變控制（AMC)或功率控制（64〇)。此時，該 層，也就是節點B 520之MAC層接收該rach訊息之 PDU，k查該MAC標頭，並檢查該下鏈通道之品質測 訊是否包括在該MAC PDU中。此時，如果該MAC標 知並未包括該下鏈通道之品質測量資訊，節點B 5 2 〇 連結該傳輸功率的控制於該品質測量資訊。 袁後’節點B 5 2 0使用根據該下鏈通道之品質測 訊所控制的傳輸功率傳輸一 rach回應訊息到 510(650)。200836503 An uplink radio resource is not guaranteed, so the RAC can be used. Said UE requests the radio resource for use in transmitting the connection request message to the network. The node receiving the radio resource configures an appropriate radio resource to the UE. The RRC Connection Request message can then be transmitted via the radio resource to a state in which the UE is RRC connected to the network, and the RACH can be used by the UE in the connected mode. In this example, the UE transmits radio data to the network according to the radio resources of the network's radio resource scheduling configuration and the configured radio resources. However, if the data to be transmitted is no longer left in the buffer of the UE, then the network does not have uplink radio resources to the UE. This is because configuring the uplink is not efficient for UEs that do not have the data to transmit. If it occurs in a buffer of a UE that does not have the radio resource, the RACH can be used because the uplink radio resource does not have a UE. That is, the UE may request the radio resource to use the RACH to transmit data to the network. That is, some RRC messages, such as an RRC connection message, a unit update message, and a URA update message, may also be transmitted by RACH. At this time, the CCCH, DCCH, DTCH, and other logical channels can be mapped to the RACH of the transport channel. The quality measurement information of the downlink channel may be included in L2i, such as a MAC header, or may be included in a share of a MAC payload, or included in a load mode in one of the payloads adjacent to the L2 header. The back end part. That is, the RACH request, the UE meal network. The RRC receiving root sends the new data via the to-be-re-configured line, and the UE sets the message to the UE for the request message: the header, the front-end MAC has 16 200836503, and then the node B 5 2 0 is used. The quality measurement of the downlink channel can be adapted to the modulation control (AMC) or power control (64〇). At this time, the layer, that is, the MAC layer of the Node B 520 receives the PDU of the rach message, k checks the MAC header, and checks whether the quality test of the downlink channel is included in the MAC PDU. At this time, if the MAC flag does not include the quality measurement information of the downlink channel, the node B 5 2 连结 controls the transmission power to control the quality measurement information. Yuan Hou's Node B 5 2 0 transmits a rach response message to 510 (650) using the transmission power controlled by the quality measurement of the downlink channel.
UE 510可包括L3資訊以及L2資訊於該RACH 中，其被傳輸到該上鏈，並包括該下鏈通道之品質測 訊於L2資訊中。此時’該L3資訊可為該rrc訊息 外，該L2資訊可通知節點b 52〇該品質測量資訊被 在該L2資訊中。尤其是，該L2資訊可為以負載方式 在該MAC標頭或MAC PDU中的MAC控制資訊，並 包括在該MAC PDU之有效負載中的MAC控制資訊。 在此步驟6 5 0中，三個以下的實例可根據該乙3 是否被包含或是該品質測量資訊是否包括在該L2資 來實施。The UE 510 may include L3 information and L2 information in the RACH, which is transmitted to the uplink and includes quality information of the downlink channel in the L2 information. At this time, the L3 information may be outside the rrc message, and the L2 information may notify the node b 52 that the quality measurement information is included in the L2 information. In particular, the L2 information may be MAC control information in the MAC header or MAC PDU in a load manner and include MAC control information in the payload of the MAC PDU. In this step 650, three or less instances may be implemented based on whether the B3 is included or whether the quality measurement information is included in the L2 asset.
首先，如果該上層資訊被包括在該MAC PDU中 該MAC標頭通知該下鏈通道的品質測量資訊被包括 則節點B 520自該MAC PDU移除該品質測量資訊， 新設置該M A C P D U。節點B 5 2 0傳送重新設置的μ A CFirst, if the upper layer information is included in the MAC PDU, the MAC header notifies that the quality measurement information of the downlink channel is included, then the Node B 520 removes the quality measurement information from the MAC PDU, and the M A C P D U is newly set. Node B 5 2 0 transmits the reset μ A C
訊執 第二 MAC 量資 頭通 即不 量資 UE 訊息 量資 〇此 包括 包括 可為 資訊 訊中 ，且 時， 並重 PDU 17 200836503 到該RNC的MAC。此外，節點B 520傳輸自UE 5 10接收 的該RACH訊息的一回應訊息到UE 5 1 〇。The second MAC measurement header is not used to fund the UE message. This includes including the information that can be used for information, and then PDU 17 200836503 to the RNC. In addition, Node B 520 transmits a response message from the RACH message received by UE 5 10 to UE 5 1 〇.
其次，如果該上層資訊並未包括在該MAC PDU中， 且該 MAC標頭通知該下鏈通道的品質測量資訊被包括 時，節點B 520即不傳送該MAC PDU到該RNC。在此例 中，節點B 520僅傳輸該RACH訊息的回應訊息到UE 5 1 0。此時，該回應訊息包括該A C K回應，以通知該R A C Η 訊息被成功地接收’與該NACK回應用於通知該RACH訊 息並未被成功接收。該回應訊息包括指示該RACH前言之 資訊或是指示該RACH訊息之資訊。此時，包括在該回應 訊息中的指示資訊可為編碼資訊，用於該訊息或該前言之 簽章的傳輸。 第三，如果該MAC標頭並未通知該下鏈通道的品質 測量資訊被包括，則節點B 520僅傳送該MAC PDU到該 RNC的MAC ’並傳輸該回應訊息到該UE 5 1 0。 節點B 520之RACH回應訊息可經由L2-PDU傳輸， 例如該MAC PDU可經由一實體層控制信號傳輸。如果該 回應訊息經由該MAC PDU傳輸，則包括該回應訊息之 MAC PDU的標頭通知UE 5 1 0該回應訊息被包括在該MAC PDU中。特別是’該UE可被通知該回應訊息包括在該MAC PDU中’其使用該MAC PDU之標頭的TCTF。 第7圖為第6圖所示之隨機存取程序的一範例。 在該RACH前言的傳輸（ Ap)及該raCH前言的回應 (AICH)之後’ UE 5 10測量節點b 520之下鏈通道，包括該 18 200836503 品質測量資訊於該MAC有效負載中或於MAC PDU之MAC 標頭中，並傳輸該RACH訊息到該上鏈。 該 RACH 訊息的節點 B 520 之回應訊息 MSG-ACK/NACK為該ACK信號，用於通知該RACH訊息 被成功接收，或為該NACK信號用於通知該RACH訊息並 未被成功接收。Secondly, if the upper layer information is not included in the MAC PDU, and the MAC header notifies that the quality measurement information of the downlink channel is included, the Node B 520 does not transmit the MAC PDU to the RNC. In this example, Node B 520 transmits only the response message of the RACH message to UE 5 1 0. At this time, the response message includes the A C K response to notify the R A C 讯息 message that the message was successfully received 'and the NACK response is used to notify that the RACH message has not been successfully received. The response message includes information indicating the RACH preamble or information indicating the RACH message. At this time, the indication information included in the response message may be coded information for transmission of the message or the signature of the preamble. Third, if the MAC header does not inform the quality measurement information of the downlink channel to be included, the Node B 520 transmits only the MAC PDU to the MAC ' of the RNC and transmits the response message to the UE 5 1 0. The RACH echo message of Node B 520 may be transmitted via the L2-PDU, for example, the MAC PDU may be transmitted via a physical layer control signal. If the response message is transmitted via the MAC PDU, the header of the MAC PDU including the response message notifies the UE 5 that the response message is included in the MAC PDU. In particular, the UE can be notified that the response message is included in the MAC PDU, which uses the TCTF of the header of the MAC PDU. Figure 7 is an example of the random access procedure shown in Figure 6. After the transmission of the RACH preamble (Ap) and the response of the raCH preamble (AICH), the UE 5 10 measures the downlink channel of the node b 520, including the 18 200836503 quality measurement information in the MAC payload or in the MAC PDU. The MAC header is transmitted and the RACH message is transmitted to the uplink. The response message MSG-ACK/NACK of the Node B 520 of the RACH message is the ACK signal, which is used to notify the RACH message that the RACH message is successfully received, or is used to notify the RACH message that the RACH message has not been successfully received.
同時，當UE 51 0自節點B 520接收該MAC PDU，並 檢查該回應訊息MSG-ACK/NACK透過該MAC PDU之標頭 包括在該 MAC PDU 中時，UE 520根據該回應訊息 MSG-ACK/NACK可重新傳輸該RACH訊息到節點B 520。 特別是，UE 510如果自節點 B 520接收的回應訊息 MSG-ACK/NACK為該ACK回應時並不重新傳輪該RACH 訊息，而如果該回應訊息為該NACK回應時則重新傳輸該 RACH訊息到節點B 520。 第8圖為根據本發明一具體實施例設置的該 MAC PDU之範例。 在第8圖中，該TCTF包括在該MAC標頭中。該TCTF 可通知該品質測量資訊（即CQI)是否被包括在該MAC PDU 中，如上所述。該MAC PDU可進一步包括其它資訊，例 如UE-Id，C/T，一 MAC服務資料單元（SDU)。 在本發明中，該行動通訊終端包括該下鏈通道的品質 測量資訊於傳輸到該上鏈的該RACH訊息之L2標頭或有 效負载中，且該無線電網路使用包括在該L2標頭或有效 負载中該品質測量資訊控制該RACH訊息的該回應訊息之 19 200836503 傳輸功率’並傳輸該回應訊息到該UE ^因此，其可能有 率地使用該無線電資源。 對於本技藝專業人士將可瞭解到可在不背離本發明 精神或範疇之下在本發明中進行多種修正及變化。因此 其係要本發明涵蓋此發明的修正及變化，如果它們在所 申請專利範圍及它們的同等範_之内。 產業應用性 根據本發明，其有可能提供一種根據用於使用一上 通道傳輪資料之一行動通訊終端的一通道測量結果用於 制一 RACH回應訊息之傳輪功率的方法。此方法可應用 一行動通訊系統之一隨機存取程序的一演算法，及用於 援它的一使用者設備及基地台。 【圖式簡單說明】 所附圖面與解說係被包含來提供對本發明更暸解， 明本發明的具體貫施例以及解釋本發明的原理。 在圖面當中’· 第1圖所示為一通用行動電信系統（UMTS)之網路 構； 第2圖為基於3 GPP無線電存取網路標準之UMTS 面無線電存取網路（UTRAN)與一使用者設備之間一無線 介面協定的結構； 第3圖為〆習用實體隨機存取通道（PRACH)傳輪； 效 之 ， 附 鏈 控 到 支 說 結 地 電 20Meanwhile, when the UE 51 0 receives the MAC PDU from the Node B 520 and checks that the response message MSG-ACK/NACK is included in the MAC PDU through the header of the MAC PDU, the UE 520 according to the response message MSG-ACK/ The NACK can retransmit the RACH message to Node B 520. In particular, the UE 510 does not retransmit the RACH message if the response message MSG-ACK/NACK received from the Node B 520 is the ACK response, and retransmits the RACH message if the response message is the NACK response. Node B 520. Figure 8 is an illustration of the MAC PDU set up in accordance with an embodiment of the present invention. In Figure 8, the TCTF is included in the MAC header. The TCTF can inform the quality measurement information (i.e., CQI) whether it is included in the MAC PDU, as described above. The MAC PDU may further include other information such as UE-Id, C/T, and a MAC Service Data Unit (SDU). In the present invention, the mobile communication terminal includes quality measurement information of the downlink channel in the L2 header or payload of the RACH message transmitted to the uplink, and the radio network usage is included in the L2 header or The quality measurement information in the payload controls the response message of the RACH message, and transmits the response message to the UE. Therefore, it may use the radio resource in a probabilistic manner. It will be apparent to those skilled in the art that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention. Therefore, it is intended that the present invention cover the modifications and variations of the invention, if they are within the scope of the claims and their equivalents.
