Traffic or control messages for downlink multicast or broadcast services (MBMS, Multimedia Broadcasting and Multicast Service; multimedia broadcast and multicast services) can be transmitted via the DL-SCH or a multicast channel (MCH). Meanwhile, an example of transmitting data from a user device to an uplink transmission channel of a network includes a random access channel (Zheng VIII (311, 1^11 (1〇111人(:06 55(311&111^ 1), it can transmit initial control messages, and an uplink shared channel (UL-SCH, uplink shared channel), which can transmit user traffic or control messages' _ _
以下將說明在WCDMA系統中的RACH。RACH用於 傳送短長度的資料到一上鍵，且一些rrc訊息’例如RRC 200835366 連接請求訊息、細胞更新訊息及URA更新訊息，皆可經由 RACH傳送。再者，一共用控制通道（CCCH， Common Control Channel)、一 專屬控制通道（DCCH，Dedicated Control Channel)、或一專屬交通通道（D TC Η， Dedicated Traffic Channel·)，其為邏輯通道之一，可對映到傳輸通道 之一的RACH。再者，為傳輸通道之一的RACH再次地對 映於實體通道之一的一實體隨機存取通道（PRACH， Physical Random Access Channel) ° 如果一使用者設備的一媒體存取控制（MAC， Medium access control)層命令該使用者設備的一實體層去執行 PRACH傳輸，貝該使用者設備的實體層選擇一存取槽及一 簽章，並根據所選擇之結果傳送PRACH前言到上鏈。該 前言在一長度為1.33ms的存取槽時段被傳送，及在16種 簽章中選出一個簽章，並在該存取槽的一第一特定長度時 段傳送該簽章。 如果該使用者設備傳送該前言，則一基地台經由為一 下鏈實體通道之一取得指標通道（AICH， Acquisition Indicator Channel)傳送一回應信號。回應於該前言所傳送 的AICH將傳送由在一存取槽的一第一特定時段的前言所 選擇的簽章，該存取槽為對應於該前言所要傳送到的該存 取槽。此時，該基地台經由傳送自AICH的簽章傳送知會 (ACK)或未知會（NACK)。如果該使用者設備接收到ACK， 則該使用者設備藉由使用對應於所傳送的簽章之一正交可 變展開因子（0VSF， Orthogonal Variable Spreading Fact〇r) 6 200835366 收 層 用 者 率 之 由 者 來 用 大 中 傳 暫 ， 備 請 置 可 無 該 碼傳送10ms或20ms之訊息部份。如果該使用者設備接 NACK，則該UE的MAC再次命令該使用者設備的實體 在一適當時間之後執行PRAC Η傳輸。同時，如果該使 者設備並不接收對應於所傳送前言的 AICH，則該使用 設備在一给定存取槽之後以高於先前刖言一個位準之功 傳送一新的前言。The RACH in a WCDMA system will be explained below. RACH is used to transmit short length data to an up key, and some rrc messages such as RRC 200835366 connection request message, cell update message and URA update message can be transmitted via RACH. Furthermore, a Common Control Channel (CCCH), a Dedicated Control Channel (DCCH), or a Dedicated Traffic Channel (D TC Η, Dedicated Traffic Channel) is one of the logical channels. RACH that can be mapped to one of the transmission channels. Furthermore, the RACH for one of the transmission channels is again mapped to a physical random access channel (PRACH) of one of the physical channels. ° If a user device has a media access control (MAC, Medium) The access control layer commands a physical layer of the user equipment to perform PRACH transmission, and the physical layer of the user equipment selects an access slot and a signature, and transmits the PRACH preamble to the uplink according to the selected result. The preamble is transmitted during an access slot period of length 1.33 ms, and a signature is selected among the 16 signatures, and the signature is transmitted during a first specific length of the access slot. If the user equipment transmits the preamble, a base station transmits a response signal by acquiring an indicator channel (AICH, Acquisition Indicator Channel) for one of the downlink physical channels. The AICH transmitted in response to the preamble will transmit the signature selected by the preamble of a first specific time period in an access slot, which is the access slot to which the preamble is to be transmitted. At this time, the base station transmits an informed (ACK) or an unknown (NACK) via a signature transmitted from the AICH. If the user equipment receives the ACK, the user equipment uses the layered user rate corresponding to one of the transmitted signatures (0VSF, Orthogonal Variable Spreading Fact〇r) 6 200835366 If you want to use the medium and large transmission, please leave the message part of the message for 10ms or 20ms. If the user equipment receives a NACK, the MAC of the UE again commands the entity of the user equipment to perform a PRAC Η transmission after an appropriate time. Meanwhile, if the messenger device does not receive the AICH corresponding to the transmitted preamble, the use device transmits a new preamble after a given access slot with a higher level than the previous rumor.
以下將說明該使用者設備藉由使用WCDMA系統中 RACH傳送訊息之範例。 對於該第一範例，處於待機模式的使用者設備經 RACH傳送一初始控制訊息到一網路。概言之，該使用 設備在當其暫時同步於該網路及其想要取得無線電資源 傳送資料到一上鏈時即使用該RACH。例如，如果該使 者設備被開機，並首次存取一新細胞，則該使用者設備 致同步於一下鏈，並在該使用者設備想要存取的一細胞 接收系統資訊。在接收到系統資訊之後，該使用者設備 送一 RRC連接存取請求訊息。但是，由於該使用者設備 時並未同步於該網路，且尚未取得該上鍵的無線電資源 因此該使用者設備使用該RACH。換言之，該使用者設 凊求該網路提供無線電資源，以經由RACH傳輸一連接 求訊息。已被請求來提供對應的無線電資源的基地台配 適當的無線電資源給該使用者設備，使得該使用者設備 傳送RRC連接請求訊息。然後，該—使—用者設備可經由該 線電資源傳送RRC連接請求訊息到該網路。 對於該第二範例，在該使用者設備以一種RRC連接 200835366 網路的狀態下，在一 RRC連接的模式中的該使用者設備使 用該RACH。在此例中，該使用者設備根據該網路的無線 電資源排程配置予無線電資源，並經由所配置的無線電資 源傳送資料到該網路。但是，如果要傳送的資料不再維持 在該使用者設備的一緩衝器中，則該網路將不會再配置該 上鏈的無線電資源。此係因為配置該上鏈的無線電資源給 無資料要傳送的使用者設備係沒有效率。An example of the user equipment transmitting a message by using RACH in a WCDMA system will be described below. For the first example, the user equipment in standby mode transmits an initial control message to a network via RACH. In summary, the device uses the RACH when it is temporarily synchronized to the network and it wants to obtain radio resources to transmit data to an uplink. For example, if the messenger device is turned on and a new cell is accessed for the first time, the user device synchronizes to the chain and receives system information at a cell that the user device wants to access. After receiving the system information, the user equipment sends an RRC connection access request message. However, since the user equipment is not synchronized to the network and the radio resource of the up key has not been obtained, the user equipment uses the RACH. In other words, the user is hoping that the network provides radio resources to transmit a connection request message via the RACH. The base station that has been requested to provide the corresponding radio resource is provided with the appropriate radio resources to the user equipment such that the user equipment transmits an RRC Connection Request message. Then, the user device can transmit an RRC Connection Request message to the network via the line resource. For the second example, the user equipment uses the RACH in an RRC connected mode in a state in which the user equipment connects to the 200835366 network. In this example, the user equipment is configured to radio resources based on the radio resource schedule of the network and transmits data to the network via the configured radio resources. However, if the data to be transmitted is no longer maintained in a buffer of the user equipment, the network will no longer configure the uplink radio resources. This is because the configuration of the uplink radio resources is inefficient for user equipment that has no data to transmit.
該使用者設備的緩衝器狀態定期性或每當發生一特定 事件時即回報給該網路。如果新的資料，發生在不具有無線 電資源之使用者設備的缓衝器中時，由於該上鏈無線電資 源並未配置給該使用者設備，因此該使用者設備使用該 RACH。換言之，該使用者設備請求該網路經由該 RACH 提供資料傳輸所需要的無線電資源。 該RACH為一上鏈共用通道，且為所有想要嘗試初始 存取到該網路之使用者設備可用到的一通道。因此，如果 同時兩個或以上的使用者設備使用該 RACH，將發生碰 撞。如果由於兩個或以上的使用者設備而發生碰撞，則該 網路應該選擇該等使用者設備之一來執行一正常程序，且 在解決由該碰撞造成的一問題之後應該執行另外其它使用 者設備之接下來程序。在此例中，在所選擇的使用者設備 之隨機存取之後，其必須定義一程序來避免程序中的延 遲，並解決了由於另外其它使用者設備的碰撞所產生的問The buffer status of the user device is reported to the network periodically or whenever a particular event occurs. If the new data occurs in a buffer of the user device that does not have the radio resource, the user equipment uses the RACH since the uplink radio resource is not configured for the user equipment. In other words, the user equipment requests the network to provide radio resources required for data transmission via the RACH. The RACH is an uplink shared channel and is available to all user devices that wish to attempt initial access to the network. Therefore, if two or more user devices use the RACH at the same time, a collision will occur. If a collision occurs due to two or more user devices, the network should select one of the user devices to perform a normal procedure, and another user should be executed after resolving a problem caused by the collision. The next program of the device. In this example, after random access by the selected user device, it must define a procedure to avoid delays in the program and resolve problems arising from collisions with other user devices.

Three floors). Providing information transfer services to the physical layer of the first layer to an upper layer using the physical channel. A physical layer (PHY) is connected to a medium access control (hereinafter abbreviated as MAC) layer above the solid layer via a transport channel. Data is transmitted between the media access control layer and the physical layer through the transport channels. Furthermore, the data is transferred between different physical layers, more specifically through a physical channel between a physical layer on one transmitting side and another physical layer on a receiving side. The physical channel of the E-UMTS is modulated according to an Orthogonal Frequency Division Multiplexing (OFDM) mode, and time and frequency are used as radio resources. The second layer of media access control (hereinafter abbreviated as mac) layer provides a service to one of the MAC layer and above radio link control (hereinafter referred to as RLC) via a logical channel. The second layer of the RLC layer supports reliable data transfer. In order to efficiently transmit IP packets (such as IPv4 or IP-v6) in a radio communication cycle with a narrow bandwidth, the PDCP layer of the second layer (L2) implements header compression to reduce the inclusion of unnecessary control information. The size of a fairly large IP packet header. 12 200835366 A radio resource control (hereinafter referred to as RRC) layer on the lowest part of the second layer is defined only in the control plane and is related to configuration, reconfiguration and control logic, transport and physical channels.

Traffic or Control Messages ^ Traffic or control messages for a chain-down multicast or broadcast service can be transmitted via the down button SCH or an additional down-key multicast channel (MCH). At the same time, because the uplink transport channel carries UE-to-network data, it provides a random access channel (RACH) carrying an initial control message, and an uplink shared channel (UL-SCH) carries user traffic or control information. When the logical channel is located above the transport channel and is mapped to the transport channel, it provides a broadcast channel (BCCH, broadcasting channel), a paging control channel (PCCH), and a shared control channel ( CCCH), a multicast control channel (MCCH), and a multicast traffic channel (MTCH), in an E-UMTS system, an OFDM is used for the downlink, and a single carrier is divided. Multiple carrier frequency division multiple access (SC-FDMA) is used for the uplink. The OFDM method using multiple carriers is configured by using a unit of multiple subcarriers including a carrier group. The 200835366 resource is used as an access method by using an orthogonal frequency division multiple access (OFDMA). A physical layer using OFDM or OFDMA schemes differentiates the enabled carriers into complex groups and transmits individual groups to different receiving sides. The radio resources of each UE configured by a time-frequency region defined on a two-dimensional sphere contain consecutive subcarriers. One of the time-frequency regions in the OFDM or OFDMA mode is a rectangular form segmented by time and subcarrier coordinates. In other words, a time-frequency region can be in the form of a rectangle on a time axis to ^ one symbol and the last carrier segment on a frequency axis. The time_frequency region may be configured to be uplinked to one of the specific UEs, or the eNB may transmit the time/frequency region to a specific one in the chain. In order to define such a time-frequency region on the two-dimensional secret surface, the number of OFDM symbols and the number of consecutive subcarriers starting from one of the discs from the disc_fighting to the reference point must be given.目月丨J Π" j/r Only when the E-UMTS uses 20 sub-frames, l〇nis 益绿带~t once', ', , , , , and the message frame.

Referring to FIG. 5, the user equipment transmits a random access base station eNB [S51]. In other words, the user equipment selects a particular signature through a plurality of signatures and transmits the selected base station. At this time, the random access preamble may include uplink information channel measurement information, so the base station can implement the uplink information transmission configuration. In this example, a collision occurs if at least two user devices simultaneously perform a random access pre-chain transmission with the same radio resource, e.g., the same signature. The base station transmits a random message to the user equipment in response to the random access preamble [S52]. The random access response packet transmits a signature of the user equipment, the random access preamble transmission information, the temporary cellular radio time identification item (temporary C-RNTI) configured for the user equipment, and the RRC Connect the control information of the request message. The information about the transmission of the RRC Connection Request message includes radio resource configuration information, a message size, and radio parameters (modulation and coding information ARQ information) for receiving the transmission of the request message. The base station transmits the signaling information for controlling the random access response message to the user equipment via L1/L2. The transmitting resource is a random access radio network temporary identification item (RA-RNTI), the transmission of the proxy access response message, and the transmission parameter regarding the random access response signal. Because the RA-RNTI was previously forwarded to the base station by the user equipment information, etc., the user equipment borrows the foreword to the access slot signature to the information or the resource is received from the usage statement and is included in the network. The information of the RC and the composite channel of the escrow control includes the transmission of the information, and the transmission of the information is obtained by using the L1/L2 control channel. The message receives the random access response message. If the signature of the signature and signature transmission transmitted from the user equipment is included in the random access response message, the user equipment transmits the RRC connection request message to the base station [S53]. At this time, the user equipment transmits the RRC connection request message to the base station by using the uplink radio resource configuration information, the message size, and the radio parameter, and is included in the random access response message. The rrC connection request message includes a user equipment identification item for identifying one of the user equipments. Examples of the user equipment identification item include a broadband UE identification item, such as an International Mobile Subscriber Identity (IMSI) or a Temporary Mobile Subscriber Identity (TMSI), if transmitted from the user equipment. The signature of the signature and the rejection information of the signature transmission are included in the random access response message, or if the signature transmitted from the user device is not included in the random access response message, the user equipment is The random access preamble is retransmitted after a certain time without transmitting the RRC connection request message. If the RRC connection request message is received from the user equipment, the RRC layer of the base station transmits the RRC connection setup message or the RRC contention resolution message to the user equipment. What is more, the RRC layer transmits an RRC message including the RRC connection setup message and the RRC contention-response message. In another example, after transmitting the connection setup message to the user equipment, the base station may transmit the RRC competition resolution message. If an RRC message including the RRC connection setup message and the rrc contention resolution message is transmitted, the extension included in the message can be reduced, whereby the radio resource can be used efficiently. The RRC message includes a user equipment identification of a user device that has successfully implemented random access. Preferably, the user equipment identifier is a user equipment identifier, such as IMSI and TMSI, included in the RRC connection request message.

In this example, the success of the user device that has successfully implemented random access represents that the random access preamble transmitted from the user has been successfully received by the base station. Then the RRC connection request has been successfully implemented. As described above, the rrc connection setting message included in the RRC message includes the broadband user equipment identifier, such as the IMSI and TMSI of the user equipment that has successfully implemented the random access. The user equipment receives control information needed to receive the rrc message via the L1/L2 control channel using its temporary C-RNTI. For example, the user equipment can identify, according to the result of the cyclic redundancy code (CRC) test of the specific channel by using the temporary C-RNTI, whether to transmit to a specific channel of one of the control channels. Yourself. For another example, if the temporary C_RNTI is received via the L1/L2 control channel, the user equipment receives a message represented by the temporary C-RNTI, and transmits it to the use from a^a 17 200835366. The device device receives the RRC message transmitted to the downlink channel of a data area, for example by using a downlink shared channel (DL-SCH) of control information transmitted via the specific channel.

At this time, the user equipment uses the temporary user equipment identification item (temporary C-RNTI) as a private c-RNTI for later communication with a network. If the broadband user equipment identification transmitted via the RRC connection request message is not included in the RRC message, the user equipment can know that the random access has failed. Meanwhile, if the RRC message including the broadband user equipment identification item is not received at a certain time, the user equipment knows that the random access has failed. At this time, the user equipment starts a random access procedure again by retransmitting the random access preamble to the base station after a certain time. The foregoing specific embodiments of the present invention may apply a random access procedure for initial access implemented after a radio link failure or delivery. Figure 6 illustrates a flow diagram of a procedure in accordance with another embodiment of the present invention. In the specific embodiment of Fig. 6, the technical feature of the present invention is applied to a random access procedure of a user equipment in an RRC connected mode. For example, if the radio resource of the material to be transmitted to the base station is not configured to the user equipment, the user equipment can transmit the material via the random access procedure via the RAC. The specific embodiment described below can be applied to the base station without being uplinked to the user equipment, even if it has downlink information to be transmitted to the user equipment in the RRc connection mode. same. Referring to FIG. 6, the user equipment transmits a random access preamble to the base station eNB [S61], and receives a random access response message from the base station in response to the random access preamble [S62]. Since steps S61 and S62 are the same as S51 and S52 of Fig. 5, detailed description thereof will be omitted.

At this time, the user equipment transmits the MAC scheduling request message to the base station by using the uplink radio resource configuration information, the message size, and the radio parameter, and is included in the random access response message. Preferably, the MAC scheduling request message includes a broadband user equipment identification item for identifying the user equipment. Examples of the user equipment identification include broadband UE identification items such as International Mobile Subscriber Identity (IMSI) or Temporary Mobile Subscriber Identity (TMSI). The specific embodiment of Figure 6 differs from Figure 5 in that the scheduling request and the contention resolution procedure are implemented by the mac layer. If the signature transmitted from the user device and the rejection information transmitted by the signature are included in the random access response message, or if the signature transmitted from the user commission is not included in the random access response message If the user equipment retransmits the random access preamble after a certain time, the MAC scheduling request message is not transmitted. If the MAC scheduling request message 19 200835366 is received from the user equipment, the MAC layer of the base station transmits a resource giving message and a MAC contention resolution message to the user equipment [S64]. The base station may simultaneously transmit the resource giving message and the MAC contention resolution message, or may transmit the MAC contention resolution message after transmitting the resource to give the message.

(RGCH, Relative Grant Channel). Conversely, the MAC contention resolution message can be transmitted in the MAC Control PDU. In addition, the base station can transmit the resource giving message and the MAC contention resolution message by combining the two in a MAC Control PDU. Furthermore, a method of transmitting the resource giving message and the MAC contention resolution message to the user equipment via the L1/L2 control channel can be considered. The MAC Control PDU includes a header and a payload, wherein the header may include information representing the MAC Control PDU, and an indicator that is included in the MAC Control PDU on behalf of the resource giving message or the MAC contention resolution message . The payload may include the content of the resource giving message or the MAC contention resolution message.

Since the user equipment in the RRC connected mode knows its private C-RNTI in advance before the attempt, the base station transmits a message including the 4 C-RNTI that has been set by the competing user. If the resource gives a message to the user via the L1, the source device gives the message as the message when the resource is given via the resource configuration channel or the L1/L2 control packet, including the private C-RNTI. . However, when the resource grant message (which does not have the private C_RNTI of the packet device) is received via the resource allocation L 1 /L2 control channel, the user device does not recognize the message as its message. If the resource gives a message to a MAC Control PDU, the control information included in the L1/L2 control channel includes the private C-RNTI of the standby to indicate that the MAC control PDU is transmitted by the user equipment only when the private The C-RNTI receives the resource giving message when it is included in the channel. The transmission from the base station via the L1/L2 control channel indicates that the transmission of the MAC contention resolution message includes the temporary. Therefore, the user equipment only receives the temporary C-RNTI when it is in the L1/L2 control channel. The MAC contention resolution message C-RNTI identifies the item from the base station user equipment via the random access response message.

In the case where the resource giving message via the L1/L2 control channel multiplexer device and the MAC contention resolution message via the data area of the user device, the operation of the user device will be clear. If the temporary C-RNTI of the user equipment receives the MAC contention indicated by the temporary C-RNTI via the L1/L2 control channel before receiving the resource information of the user equipment, the user equipment identifies the MAC contention. Resolve whether the message is the private C-RNTI of the packet device. If the user sets 1 C-RNTI to be included in the MAC contention resolution message, the user should be aware that they have successfully implemented the random access and monitor the receipt of the message via the resource of the control channel, including the enablement Private C-RNTI. If the resource is given a message at a certain time period previously set, the user device starts the program again. If the resource is received within the certain time period, the user equipment gives the non-transported uplink data configured by the message to the base station via the resource. If the user equipment receives the resource granting message via the L1/L2 control channel after receiving the MAC contention resolution, the C-RNTI, the user equipment, can be resolved to have successfully accessed the machine. Regardless of whether the MAC contention resolution message is received or not, the resource is assigned to the radio resource transmission by the resource, and the uplink device is sent to the domain for transmission to the following to receive from the base, and the message: The user device does not receive the random access message in the L1/L2 user device, and the line resource message previously includes the private implementation and is sent to the base 22 200835366. If the user equipment receives its temporary C-RNTI via the L1/L2 control channel after receiving the resource giving message, the user equipment ignores the packet data represented by the temporary C-RNTI.
