Description

資訊指示方法、使用者設備及基地台 Information instruction method, user equipment and base station

本發明屬於通信技術領域，尤其是關於一種資訊指示方法、使用者設備及基地台。 The invention belongs to the field of communication technology, and particularly relates to an information indication method, user equipment and base station.

在LTE(Long Term Evolution，長期演進)系統中，MAC RAR PDU(Media Access Control Random Access Response Protocol Data Unit，媒體存取控制隨機存取回應協定資料單元)由MAC頭(MAC header)與MAC負荷(MAC payload)組成。當調度資源的大小大於MAC頭以及MAC負荷所需資源的大小時，剩下的部分需要填入填充位元(即padding)。使用者設備(User Equipment，UE)接收到MAC RAR PDU後可以獲取MAC頭以及MAC負荷的大小，然後根據MAC RAR PDU大小減去MAC頭加MAC負荷(MAC payload)的和，即得到padding大小。 In LTE (Long Term Evolution, Long Term Evolution) system, MAC RAR PDU (Media Access Control Random Access Response Protocol Data Unit) consists of MAC header (MAC header) and MAC load ( MAC payload). When the size of the scheduling resource is greater than the size of the MAC header and the resources required by the MAC load, the remaining part needs to be filled with padding bits (ie padding). After receiving the MAC RAR PDU, the user equipment (UE) can obtain the size of the MAC header and the MAC load, and then subtract the sum of the MAC header and the MAC payload according to the size of the MAC RAR PDU to obtain the padding size.

下一代移動通信系統中，MAC RAR PDU(Media Access Control Random Access Response Protocol Data Unit，媒體存取控制隨機存取回應協定資料單元)由多個MAC subPDU(MAC子PDU)構成，每個MAC subPDU具有獨立的指示功能。然而，由於上述MAC RAR PDU結構，使用者設備無法確定MAC RAR PDU中的padding，舉例而言，假設padding 為全1，使用者設備解析時將其當作一種MAC子PDU並遵照執行，容易發生錯誤且增加使用者設備的耗電量。 In the next generation mobile communication system, MAC RAR PDU (Media Access Control Random Access Response Protocol Data Unit) is composed of multiple MAC subPDUs (MAC sub PDUs), each of which has Independent indication function. However, due to the above-mentioned MAC RAR PDU structure, the user equipment cannot determine the padding in the MAC RAR PDU. For example, assuming that padding is all 1, the user equipment interprets it as a MAC sub-PDU and executes it in compliance, which is easy to occur Error and increase the power consumption of user equipment.

可見，下一代移動通信系統中，使用者設備無法確定MAC RAR PDU中的padding，遇到MAC RAR PDU中的padding部分會進行不必要的解析，增加了使用者設備的耗電量。 It can be seen that in the next generation mobile communication system, the user equipment cannot determine the padding in the MAC RAR PDU, and the padding portion of the MAC RAR PDU will be analyzed unnecessarily, which increases the power consumption of the user equipment.

As shown in FIG. 1, it includes a user equipment (User Equipment, UE) 11 and a base station 12, wherein the user equipment 11 may be a mobile phone , Tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital assistant, PDA for short), mobile Internet device (Mobile Internet Device, MID) or wearable device (Wearable Device), etc. It should be noted that the terminal-side device does not limit the specific type of the user device 11 in the embodiment of the present invention. The base station 12 may be, for example, a macro station, LTE eNB, 5G NR NB (fifth generation mobile communication system base station), etc. It should be noted that the specific type of the base station 12 is not limited in the embodiment of the present invention.

LTE系統的競爭隨機存取用於以下目的：使用者設備初始存取；RRC(Radio Resource Control，無線資源控制)連接重建或切換；非同步狀態下RRC連接態時下行資料到達；RRC連接態時上行資料到達；RRC連接態時的定位。下一代移動通信系統(NR)中還引入系統消息請求、inactive UE(非啟動態使用者設備)恢復連接等目的。 Competitive random access in the LTE system is used for the following purposes: user equipment initial access; RRC (Radio Resource Control, radio resource control) connection re-establishment or handover; downlink data arrives in the RRC connection state in the asynchronous state; when the RRC connection state Upstream data arrives; location when RRC is connected. The next-generation mobile communication system (NR) also introduces the purposes of system message request, inactive UE (non-active user equipment) restoration of connection, etc.

請參閱圖2，圖2是一種競爭隨機存取過程示意圖，如圖2所示，競爭隨機存取過程主要包括： Msg201、使用者設備選擇隨機存取前導碼(Random Access Preamble)以及PRACH(Physical Random Access Channel，物理隨機存取通道)，並在選擇的PRACH資源上向基地台發送所選的隨機存取前導碼。在NR中，可以為基於Msg201系統消息請求(Msg201 based SI request)預留特定的隨機存取前導碼和/或PRACH資源。 Please refer to FIG. 2. FIG. 2 is a schematic diagram of a contention random access process. As shown in FIG. 2, the contention random access process mainly includes: Msg201, user equipment selection random access preamble (Random Access Preamble) and PRACH (Physical Random Access Channel, physical random access channel), and send the selected random access preamble to the base station on the selected PRACH resource. In the NR, a specific random access preamble and/or PRACH resource may be reserved for Msg201 based SI request.

Msg202、基地台接收到使用者設備發送的隨機存取請求(即Msg201)，向使用者設備發送隨機存取回應。隨機存取回應中可以包含上行定時提前量、為上行調度傳輸分配的上行資源調度信令(UL grant)、網路側為使用者設備分配的臨時C-RNTI(Cell Radio Network Temporary Identifier，小區無線網路臨時標識)。承載該Msg202的調度消息的PDCCH(Physical Downlink Control Channel，物理下行控制通道)可以用RA-RNTI(Random Access Radio Network TemporaryIdentifier，隨機存取無線網路臨時標識)加擾。Msg202還可以攜帶前導序列(preamble ID)，使用者設備可以通過RA-RNTI及preamble ID確定該Msg202是否與其發送的Msg201對應。 Msg202, the base station receives the random access request (ie, Msg201) sent by the user equipment, and sends a random access response to the user equipment. The random access response may include uplink timing advance, uplink resource scheduling signaling (UL grant) allocated for uplink scheduled transmission, and temporary C-RNTI (Cell Radio Network Temporary Identifier) allocated to user equipment on the network side. Road temporary signs). The PDCCH (Physical Downlink Control Channel) carrying the scheduling message of the Msg202 can be scrambled with RA-RNTI (Random Access Radio Network Temporary Identifier, random access wireless network temporary identifier). The Msg202 may also carry a preamble ID (preamble ID), and the user equipment may determine whether the Msg202 corresponds to the Msg201 sent by the RA-RNTI and the preamble ID.

在NR中，針對基於Msg201的系統消息請求，Msg202可以只包含與Msg201對應的preamble ID資訊，而不包括其他內容。此外，在NR中，對於基於Msg201的系統消息請求場景，隨機存取過程到Msg202結束，即如果接收到的Msg202中包含與Msg201發送的preamble對應的preamble ID，則認為基於Msg201的系統消息請求過程完成。 In NR, for the system message request based on Msg201, Msg202 may only contain preamble ID information corresponding to Msg201, but not other content. In addition, in the NR, for the system message request scenario based on Msg201, the random access process ends at Msg202, that is, if the received Msg202 contains a preamble ID corresponding to the preamble sent by Msg201, the system message request process based on Msg201 is considered carry out.

Msg203、使用者設備在Msg202指定的UL grant上發送上行傳輸，不同隨機存取原因Msg203上行傳輸的內容不同，例如對於初始存取，Msg203傳輸的是RRC連接建立請求。 Msg203. The user equipment sends an uplink transmission on the UL grant specified by Msg202. The contents of the uplink transmission are different for different random access reasons. For example, for initial access, Msg203 transmits an RRC connection establishment request.

Msg204、競爭解決消息(Contention Resolution)，使用者設備根據Msg204可以判斷隨機存取是否成功，對於初始存取的使用者設備，競爭解決成功後其在小區的臨時C-RNTI自動轉化為使用者設備在該小區的唯一使用者設備標識C-RNTI。 Msg204, contention resolution message (Contention Resolution), the user equipment can determine whether the random access is successful according to Msg204. For the initial access user equipment, the temporary C-RNTI in the cell is automatically converted into user equipment after the contention resolution is successful The unique user equipment identity in the cell is C-RNTI.

非競爭隨機存取用於切換、下行資料到達、定位以及獲取上行定時。參閱圖3，圖3是一種非競爭隨機存取過程的示意圖，如圖3所示，非競爭隨機存取過程主要包括：Msg301、基地台向使用者設備發送隨機存取前導序列分配(RA Preamble assignment)消息，該隨機存取前導序列分配消息包含基地台為使用者設備分配的用於非競爭隨機存取的專用preamble以及隨機存取使用的PRACH資源； Msg302、使用者設備根據Msg301的指示，在指定的PRACH資源上向基地台發送指定的專用preamble。基地台接收到Msg302後可以根據Msg302計算上行定時提前量TA；Msg303、基地台向使用者設備發送隨機存取回應，隨機存取回應中包含定時提前量資訊、後續上行傳輸資源配置UL grant，定時提前量用於使用者設備確定後續上行傳輸的定時關係。 Non-contention random access is used for handover, downlink data arrival, positioning, and acquisition of uplink timing. Referring to FIG. 3, FIG. 3 is a schematic diagram of a non-contention random access process. As shown in FIG. 3, the non-contention random access process mainly includes: Msg301, the base station sends a random access preamble sequence allocation to the user equipment (RA Preamble assignment) message, the random access preamble assignment message includes a dedicated preamble for non-contention random access allocated by the base station to the user equipment and PRACH resources used for random access; Msg302, the user equipment according to the instructions of Msg301, Send the designated dedicated preamble to the base station on the designated PRACH resource. After receiving the Msg302, the base station can calculate the uplink timing advance TA according to the Msg302; The advance is used by the user equipment to determine the timing relationship of subsequent uplink transmission.

在LTE系統中，MAC RAR PDU包括一個MAC頭，該MAC RAR PDU還可以包括MAC負荷和/或padding，其中MA負荷包括一個或多個MAC RAR(Media Access Control Random Access Response，媒體存取控制隨機存取回應)。參見圖4，圖4是LTE系統中的一種的MAC RAR PDU結構示意圖，如圖4所示，MAC頭包括一個或多個MAC子頭，一個MAC RAR PDU中至多可以包括一個攜帶BI(Backoff Indicator回退指示)的MAC子頭，即如圖4所示的BI subheader。攜帶BI的MAC子頭不與MAC RAR對應，其他MAC子頭分別對應一個MAC RAR。當調度資源的大小等於MAC頭以及MAC RAR所需資源的大小時，MAC RAR PDU不需要填充；當調度資源的大小大於MAC頭以及MAC RAR所需資源的大小時，剩下的部分需要填入填充位元，即padding。也就是說，一個MAC RAR PDU中可以包括padding，也可以不包括padding，即圖4中的padding為可選的(opt)。 In the LTE system, the MAC RAR PDU includes a MAC header, and the MAC RAR PDU may also include MAC load and/or padding, where the MA load includes one or more MAC RAR (Media Access Control Random Access Response, media access control random Access response). Referring to FIG. 4, FIG. 4 is a schematic diagram of a MAC RAR PDU structure in an LTE system. As shown in FIG. 4, the MAC header includes one or more MAC sub-headers, and at most one MAC RAR PDU may include a BI (Backoff Indicator). The MAC subheader of the back-off indication), that is, the BI subheader shown in FIG. 4. The MAC subheader carrying BI does not correspond to the MAC RAR, and the other MAC subheaders each correspond to a MAC RAR. When the size of the scheduling resource is equal to the size of the MAC header and the resources required by the MAC RAR, the MAC RAR PDU does not need to be filled; when the size of the scheduling resource is larger than the size of the MAC header and the resources required by the MAC RAR, the remaining part needs to be filled in Fill bits, padding. In other words, a MAC RAR PDU may or may not include padding, that is, padding in FIG. 4 is optional (opt).

LTE系統中的MAC子頭格式包括兩種，一種是攜帶BI的MAC子頭，一種是攜帶RAPID(Random Access preamble ID，隨機存取前導序列)的MAC子頭，例如圖4中的RAPID subheader，攜帶RAPID的子頭總是和一個MAC RAR對應。 The MAC subheader format in the LTE system includes two types, one is a MAC subheader carrying BI, and the other is a MAC subheader carrying RAPID (Random Access preamble ID), such as the RAPID subheader in FIG. 4, The subheader carrying RAPID always corresponds to a MAC RAR.

攜帶RAPID的MAC子頭為E/T/RAPID subheader，即包含E域、T域以及RAPID，攜帶RAPID的MAC子頭的結構請參閱圖5。攜帶BI的MAC子頭為E/T/R/R/BI subheader，即包含E域、T域、保留位元R以及BI。攜帶BI的MAC子頭的結構請參閱圖6。 The MAC subheader carrying RAPID is an E/T/RAPID subheader, which includes the E domain, T domain, and RAPID. For the structure of the MAC subheader carrying RAPID, see FIG. 5. The MAC subheader carrying BI is E/T/R/R/BI subheader, that is, it contains the E domain, T domain, reserved bits R and BI. Refer to Figure 6 for the structure of the MAC subheader carrying BI.

參閱圖7，圖7是LTE系統中的一種MAC RAR結構示意圖，如圖7所示，MAC RAR的各域含義分別為：R：預留位元；Timing Advance Command：定時提前命令，用於指示使用者設備發送上行資料的時間調整量，佔用11bit；UL Grant：資源配置域，用於指示上行資源配置，佔用20bit；Temporary C-RNTI：臨時C-RNTI，只對競爭隨機存取有用。 Referring to FIG. 7, FIG. 7 is a schematic diagram of a MAC RAR structure in an LTE system. As shown in FIG. 7, the meanings of the MAC RAR fields are as follows: R: reserved bits; Timing Advance Command: timing advance command, used to indicate The amount of time to adjust the uplink data sent by the user equipment occupies 11 bits; UL Grant: resource configuration field, used to indicate uplink resource configuration, occupies 20 bits; Temporary C-RNTI: temporary C-RNTI, only useful for contention random access.

其中，在LTE系統中，一個MAC子頭中各域含義分別為：E：指示該MAC子頭的後續資訊的類型，即指示該MAC子頭的後續資訊為MAC子頭還是MAC payload；T：指示該MAC子頭為BI子頭還是RAR子頭；RAPID：與隨機存取請求中的preamble ID對應；BI：回退指示。 Among them, in the LTE system, the meanings of each field in a MAC subheader are as follows: E: indicates the type of subsequent information of the MAC subheader, that is, indicates whether the subsequent information of the MAC subheader is the MAC subheader or the MAC payload; T: Indicates whether the MAC sub-header is a BI sub-header or a RAR sub-header; RAPID: corresponds to the preamble ID in the random access request; BI: back-off indication.

LTE中，使用者設備接收到MAC RAR PDU後，可以解析MAC頭，獲取MAC頭以及MA負荷的大小，然後根據MAC RAR PDU大小減去MAC頭加MAC負荷(MAC payload)的和，即得到padding大小。 In LTE, after receiving the MAC RAR PDU, the user equipment can parse the MAC header to obtain the size of the MAC header and the MA load, and then subtract the sum of the MAC header plus the MAC payload according to the size of the MAC RAR PDU to obtain padding. size.

在下一代移動通信系統(例如5G NR，第五代移動通信系統)中，MAC RAR PDU的結構改為包括多個MAC subPDU(MAC子PDU)，如圖8所示，每個MAC subPDU具有獨立的指示功能。 In the next-generation mobile communication system (for example, 5G NR, fifth-generation mobile communication system), the structure of the MAC RAR PDU is changed to include multiple MAC subPDUs (MAC sub-PDUs), as shown in FIG. 8, each MAC subPDU has an independent Indication function.

MAC subPDU包括以下三種類型：指示BI的MAC subPDU，該類MAC subPDU只有一個MAC子頭；指示MAC RAR的MAC subPDU，該類MAC subPDU包括一個MAC子頭以及一個MAC RAR；指示系統消息請求回應的MAC subPDU，該類MAC subPDU只有一個MAC子頭。 MAC subPDUs include the following three types: MAC subPDUs indicating BI, which has only one MAC subheader; MAC subPDUs indicating MAC RAR, which includes a MAC subheader and a MAC RAR; indicating system message request responses The MAC subPDU has only one MAC subheader.

然而，由於5G NR的MAC RAR PDU包括一個或多個MAC subPDU，使用者終端不能從MAC subPDU中推導出padding部分的大小。基於上述問題，本發明實施例提供一種資訊指示方法，以下將結合具體實施例對本發明進行詳細描述。 However, since the MAC RAR PDU of 5G NR includes one or more MAC subPDUs, the user terminal cannot derive the size of the padding part from the MAC subPDU. Based on the above problems, embodiments of the present invention provide an information indication method. The present invention will be described in detail in conjunction with specific embodiments below.

請參見圖9，圖9是本發明實施例提供的一種資訊指示方法的流程圖，該方法應用於使用者設備中，如圖9所示，該方法包括：步驟901、接收基地台發送的MAC RAR PDU，該MAC RAR PDU中攜帶有padding指示資訊；步驟902、根據該MAC RAR PDU中的padding指示資訊，確定該MAC RAR PDU中的padding。 Please refer to FIG. 9. FIG. 9 is a flowchart of an information indication method provided by an embodiment of the present invention. The method is applied to user equipment. As shown in FIG. 9, the method includes: Step 901: Receive a MAC sent by a base station RAR PDU, the MAC RAR PDU carries padding indication information; Step 902, according to the padding indication information in the MAC RAR PDU, determine the padding in the MAC RAR PDU.

本發明實施例中，使用者設備向基地台發送隨機存取請求後，該基地台根據待發送資料的大小以及調度資源的大小構造攜帶有padding指示資訊的MAC RAR PDU，並向該使用者設備發送。該使用者設備接收基地台發送的MAC RAR PDU，並根據該MAC RAR PDU中的padding指示資訊，確定該MAC RAR PDU中的padding。 In the embodiment of the present invention, after the user equipment sends a random access request to the base station, the base station constructs a MAC RAR PDU carrying padding indication information according to the size of the data to be sent and the size of the scheduling resource, and sends it to the user equipment send. The user equipment receives the MAC RAR PDU sent by the base station, and determines the padding in the MAC RAR PDU according to the padding indication information in the MAC RAR PDU.

該MAC RAR PDU包括一個或多個MAC subPDU，該padding指示資訊可以攜帶在MAC subPDU的MAC子頭中，MAC子頭中攜帶的padding指示資訊可以指示當前MAC subPDU之後是否為padding，也可以指示當前MAC subPDU是否為padding。該當前MAC subPDU之後指緊隨該當前MAC subPDU，即從當前MAC subPDU結束之後的下一個位元組開始計算。如果當前MAC subPDU之後為padding，則表示從當前MAC subPDU結束後的下一個位元組開始都是padding。 The MAC RAR PDU includes one or more MAC subPDUs, and the padding indication information can be carried in the MAC subheader of the MAC subPDU, and the padding indication information carried in the MAC subheader can indicate whether the current MAC subPDU is padding after, or can also indicate the current Whether the MAC subPDU is padding. The current MAC subPDU refers to the current MAC subPDU immediately after it is calculated from the next byte after the current MAC subPDU ends. If the current MAC subPDU is followed by padding, it means that padding will begin from the next byte after the end of the current MAC subPDU.

該基地台可以將padding指示攜帶在非padding的MAC subPDU的MAC子頭，也可以引入MAC padding子頭，並在MAC子頭中引入區分指示位用於指示padding子頭。 The base station may carry the padding indication in the MAC subheader of the non-padding MAC subPDU, or introduce a MAC padding subheader, and introduce a distinguishing indicator bit in the MAC subheader to indicate the padding subheader.

可選地，該MAC RAR PDU包括一個或多個MAC subPDU，該MAC subPDU至少包括非padding的MAC subPDU，每個非padding的MAC subPDU含有MAC子頭，每個MAC子頭中攜帶用於指示當前MAC subPDU之後是否為padding的padding指示資訊。 Optionally, the MAC RAR PDU includes one or more MAC subPDUs, the MAC subPDU includes at least non-padding MAC subPDUs, each non-padding MAC subPDU contains a MAC subheader, and each MAC subheader carries a After the MAC subPDU, it indicates whether the padding is padding.

該實施例中，padding指示資訊攜帶在非padding的MAC subPDU的MAC子頭中，MAC子頭中攜帶的padding指示資訊指示當前MAC subPDU之後是否為padding。 In this embodiment, the padding indication information is carried in the MAC subheader of the non-padding MAC subPDU, and the padding indication information carried in the MAC subheader indicates whether the current MAC subPDU is padding after.

參見圖10，圖10是本發明實施例提供的一種MAC RAR PDU的結構示意圖，如圖10所示，該MAC RAR PDU包括一個或多個MAC subPDU，該MAC subPDU至少包括非padding的MAC subPDU，每個非padding的MAC subPDU含有MAC子頭，其中，每個MAC子頭中攜帶padding指示資訊。需要說明的是，如圖10所示，該實施例中將padding作為一個特殊的MAC subPDU，padding部分沒有對應的MAC子頭。 Referring to FIG. 10, FIG. 10 is a schematic structural diagram of a MAC RAR PDU provided by an embodiment of the present invention. As shown in FIG. 10, the MAC RAR PDU includes one or more MAC subPDUs, and the MAC subPDU includes at least non-padding MAC subPDUs. Each non-padding MAC subPDU contains a MAC sub-header, where each MAC sub-header carries padding indication information. It should be noted that, as shown in FIG. 10, in this embodiment, padding is used as a special MAC subPDU, and the padding part does not have a corresponding MAC subheader.

可選地，利用每個MAC子頭中的佔用1位元的E域指示當前MAC subPDU之後是否為padding。 Optionally, the E field occupying 1 bit in each MAC subheader is used to indicate whether the current MAC subPDU is padding after.

當padding指示資訊攜帶在非padding的MAC subPDU的MAC子頭中，且該padding指示資訊用於指示當前MAC subPDU之後是否為padding時，該方法可以利用每個MAC子頭中佔用1位元的E域指示當前MAC subPDU之後是否為padding。 When the padding indication information is carried in the MAC sub-header of the non-padding MAC subPDU, and the padding indication information is used to indicate whether the current MAC subPDU is padding afterwards, the method can use E that occupies 1 bit in each MAC sub-header The field indicates whether the current MAC subPDU is padding.

該方法可以複用LTE系統中的MAC子頭格式，具體地，由於MAC RAR PDU的結構變更為包括多個MAC subPDU，LTE系統中MAC子頭的E域的作用不再需要，因此可以利用MAC子頭中的E域指示下一個MAC subPDU是否為padding，即複用MAC子頭中的E域指示下一個MAC subPDU是否為padding，例如使用第一預設值的E域指示下一個MAC subPDU為padding。該實施例中，指示RAPID的MAC子頭與LTE系統中指示RAPID的MAC子頭格式相同，如圖5所示；指示BI的MAC子頭與LTE系統中指示BI的MAC子頭格式相同，如圖6所示。 This method can reuse the MAC subheader format in the LTE system. Specifically, since the structure of the MAC RAR PDU is changed to include multiple MAC subPDUs, the role of the E domain of the MAC subheader in the LTE system is no longer needed, so the MAC can be used The E field in the subheader indicates whether the next MAC subPDU is padding, that is, the E field in the multiplexed MAC subheader indicates whether the next MAC subPDU is padding, for example, the E field using the first preset value indicates the next MAC subPDU is padding. In this embodiment, the format of the MAC subheader indicating RAPID is the same as the format of the MAC subheader indicating RAPID in the LTE system, as shown in FIG. 5; the format of the MAC subheader indicating BI is the same as the format of the MAC subheader indicating BI in the LTE system, such as Figure 6 shows.

可選地，前述根據該MAC RAR PDU中的padding指示資訊，確定該MAC RAR PDU中的padding，包括：解析每個MAC subPDU的MAC子頭中的E域；若目標MAC subPDU的MAC子頭中的E域為第一預設值，確定該目標MAC subPDU之後為padding。 Optionally, determining the padding in the MAC RAR PDU according to the padding indication information in the MAC RAR PDU includes: parsing the E field in the MAC subheader of each MAC subPDU; if the target MAC subPDU has the MAC subheader The E field of is the first preset value, and the padding is determined after the target MAC subPDU.

該實施例中，該方法利用MAC子頭中第一預設值的E域指示下一個MAC subPDU為padding。具體地，該使用者設備解析每個MAC subPDU的MAC子頭中的E域，並判斷每個MAC subPDU的MAC子頭中的E域是否為第一預設值；若目標MAC subPDU的MAC子頭中的E域為該第一預設值，該使用者設備確定該目標MAC subPDU之後為padding。若目標MAC subPDU的MAC子頭中的E域不為該第一預設值，該使用者設備確定該目標MAC subPDU之後不為padding。 In this embodiment, the method uses the E field of the first preset value in the MAC subheader to indicate that the next MAC subPDU is padding. Specifically, the user equipment parses the E field in the MAC sub-header of each MAC subPDU, and determines whether the E field in the MAC sub-header of each MAC subPDU is the first preset value; The E field in the header is the first preset value, and the user equipment determines that the target MAC subPDU is padding. If the E field in the MAC subheader of the target MAC subPDU is not the first preset value, the user equipment determines that the target MAC subPDU is not padding afterwards.

該第一預設值可以為1，也可以為0，本發明實施例對此不作限定。以該第一預設值為1為例，若目標MAC subPDU的MAC子頭中的E域為1，該使用者設備確定該目標MAC subPDU之後為padding；若目標MAC subPDU的MAC子頭中的E域為0，該使用者設備確定該目標MAC subPDU之後不為padding。 The first preset value may be 1 or 0, which is not limited in this embodiment of the present invention. Taking the first preset value of 1 as an example, if the E field in the MAC sub-header of the target MAC subPDU is 1, the user equipment determines that the target MAC subPDU is padding; if the When the E field is 0, the user equipment determines that the target MAC subPDU is not padding.

可以理解的是，該實施例中，當基地台構造該攜帶有padding指示資訊的MAC RAR PDU時，若目標MAC subPDU之後為padding，該基地台將該目標MAC subPDU的MAC子頭中的E域設置為該第一預設值，例如1；若目標MAC subPDU之後不為padding，該基地台將該目標MAC subPDU的MAC子頭中的E域設置為不等於該第一預設值，例如0。 It can be understood that in this embodiment, when the base station constructs the MAC RAR PDU carrying the padding indication information, if the target MAC subPDU is followed by padding, the base station uses the E field in the MAC subheader of the target MAC subPDU Set to the first preset value, for example 1; if the target MAC subPDU is not followed by padding, the base station sets the E field in the MAC subheader of the target MAC subPDU to be not equal to the first preset value, for example 0 .

可選地，該MAC RAR PDU包括一個或多個MAC subPDU，每個MAC subPDU含有MAC子頭，每個MAC子頭中攜帶用於指示當前MAC subPDU是否為padding的padding指示資訊。 Optionally, the MAC RAR PDU includes one or more MAC subPDUs, each MAC subPDU contains a MAC subheader, and each MAC subheader carries padding indication information indicating whether the current MAC subPDU is padding.

該實施例中的MAC RAR PDU結構如圖11所示，該方法引入MAC padding子頭(圖11所示的padding subheader)，即將MAC padding子頭與padding組成一個特殊的MAC subPDU，每個MAC子頭中攜帶的padding指示資訊用於指示當前MAC subPDU是否為padding。 The structure of the MAC RAR PDU in this embodiment is shown in FIG. 11, and this method introduces a MAC padding subheader (padding subheader shown in FIG. 11), that is, a special MAC subPDU is formed by the MAC padding subheader and padding. The padding indication information carried in the header is used to indicate whether the current MAC subPDU is padding.

具體地，每個MAC子頭中攜帶的padding指示資訊用於指示當前MAC子頭是否為MAC padding子頭，若當前MAC子頭為MAC padding子頭，則當前MAC subPDU為padding；若當前MAC子頭不為MAC padding子頭，則當前MAC subPDU不為padding。 Specifically, the padding indication information carried in each MAC subheader is used to indicate whether the current MAC subheader is a MAC padding subheader. If the current MAC subheader is a MAC padding subheader, the current MAC subPDU is padding; if the current MAC subheader If the header is not a MAC padding sub-header, the current MAC subPDU is not padding.

可選地，利用該每個MAC子頭中的佔用1位元的E域指示當前MAC subPDU是否為padding。 Optionally, the E field occupying 1 bit in each MAC subheader is used to indicate whether the current MAC subPDU is padding.

當MAC子頭中的padding指示資訊用於指示當前MAC subPDU是否為padding時，該方法可以利用該每個MAC子頭中佔用1位元的E域指示當前MAC subPDU是否為padding。 When the padding indication information in the MAC subheader is used to indicate whether the current MAC subPDU is padding, the method can use the E field occupying 1 bit in each MAC subheader to indicate whether the current MAC subPDU is padding.

該方法可以複用LTE系統中的MAC子頭格式，具體地，由於MAC RAR PDU的結構變更為包括多個MAC subPDU，LTE系統中MAC子頭的E域的作用不再需要，因此可以利用MAC子頭中的E域指示當前MAC subPDU是否為padding，即複用MAC子頭中的E域指示當前MAC subPDU是否為padding，例如使用第二預設值的E域指示當前MAC subPDU為padding。該實施例中，指示RAPID的MAC子頭與LTE系統中指示RAPID的MAC子頭格式相同，如圖5所示；指示BI的MAC子頭與LTE系統中指示BI的MAC子頭格式相同，如圖6所示；指示padding的MAC padding子頭的格式如圖12所示，其中，圖12所示的格式中LCID為邏輯通道標識(logical channel identify)。 This method can reuse the MAC subheader format in the LTE system. Specifically, since the structure of the MAC RAR PDU is changed to include multiple MAC subPDUs, the role of the E domain of the MAC subheader in the LTE system is no longer needed, so the MAC can be used The E field in the subheader indicates whether the current MAC subPDU is padding, that is, the E field in the multiplexed MAC subheader indicates whether the current MAC subPDU is padding, for example, the E field using the second preset value indicates that the current MAC subPDU is padding. In this embodiment, the format of the MAC subheader indicating RAPID is the same as the format of the MAC subheader indicating RAPID in the LTE system, as shown in FIG. 5; the format of the MAC subheader indicating BI is the same as the format of the MAC subheader indicating BI in the LTE system, such as Figure 6; the format of the MAC padding subheader indicating padding is shown in Figure 12, where the LCID in the format shown in Figure 12 is a logical channel identifier.

可選地，前述根據該MAC RAR PDU中的padding指示資訊，確定該MAC RAR PDU中的padding，包括：解析每個MAC subPDU的MAC子頭中的E域；若目標MAC subPDU的MAC子頭中的E域為第二預設值，確定該目標MAC subPDU為padding。 Optionally, determining the padding in the MAC RAR PDU according to the padding indication information in the MAC RAR PDU includes: parsing the E field in the MAC subheader of each MAC subPDU; if the target MAC subPDU has the MAC subheader The E field of is the second preset value, and it is determined that the target MAC subPDU is padding.

該實施例中，該方法利用MAC子頭中第二預設值的E域指示當前MAC subPDU為padding。具體地，該使用者設備解析每個MAC subPDU的MAC子頭中的E域，並判斷每個MAC subPDU的MAC子頭中的E域是否為第二預設值；若目標MAC subPDU的MAC子頭中的E域為該第二預設值，該使用者設備確定該目標MAC subPDU為padding。若目標MAC subPDU的MAC子頭中的E域不為該第二預設值，該使用者設備確定該目標MAC subPDU不為padding。 In this embodiment, the method uses the second preset value E field in the MAC subheader to indicate that the current MAC subPDU is padding. Specifically, the user equipment parses the E field in the MAC sub-header of each MAC subPDU and determines whether the E field in the MAC sub-header of each MAC subPDU is the second preset value; if the MAC sub-target MAC subPDU The E field in the header is the second preset value, and the user equipment determines that the target MAC subPDU is padding. If the E field in the MAC subheader of the target MAC subPDU is not the second preset value, the user equipment determines that the target MAC subPDU is not padding.

該第二預設值可以為1，也可以為0，本發明實施例對此不作限定。以該第二預設值為1為例，若目標MAC subPDU的MAC子頭中的E域為1，該使用者設備確定該目標MAC subPDU為padding；若目標MAC subPDU的MAC子頭中的E域為0，該使用者設備確定該目標MAC subPDU不為padding。 The second preset value may be 1 or 0, which is not limited in this embodiment of the present invention. Taking the second preset value as an example, if the E field in the MAC subheader of the target MAC subPDU is 1, the user equipment determines that the target MAC subPDU is padding; if the E in the MAC subheader of the target MAC subPDU The field is 0, and the user equipment determines that the target MAC subPDU is not padding.

可以理解的是，該實施例中，當基地台構造該攜帶有padding指示資訊的MAC RAR PDU時，若目標MAC subPDU為padding，該基地台將該目標MAC subPDU的MAC子頭中的E域設置為該第二預設值，例如1；若目標MAC subPDU不為padding，該基地台將該目標MAC subPDU的MAC子頭中的E域設置為不等於該第二預設值，例如0。 It can be understood that, in this embodiment, when the base station constructs the MAC RAR PDU carrying the padding indication information, if the target MAC subPDU is padding, the base station sets the E field in the MAC subheader of the target MAC subPDU Is the second preset value, for example 1; if the target MAC subPDU is not padding, the base station sets the E field in the MAC subheader of the target MAC subPDU to be not equal to the second preset value, for example 0.

可選地，利用該每個MAC子頭中攜帶隨機存取前導序列RAPID的情況指示當前MAC subPDU是否為padding。 Optionally, the situation that each MAC subheader carries a random access preamble sequence RAPID is used to indicate whether the current MAC subPDU is padding.

當MAC子頭中的padding指示資訊用於指示當前MAC subPDU是否為padding時，該方法可以利用該每個MAC子頭中攜帶RAPID的情況指示當前MAC subPDU是否為padding。 When the padding indication information in the MAC subheader is used to indicate whether the current MAC subPDU is padding, the method can use the condition that each MAC subheader carries RAPID to indicate whether the current MAC subPDU is padding.

該方法可以複用LTE系統中指示RAR的MAC子頭格式指示padding，並且不再使用MAC子頭中的E域，即將MAC子頭中的E域設置為R域，即保留位元。該實施例中，指示RAR的MAC子頭格式如圖13所示，指示BI的MAC子頭格式如圖14所示。該方法可以利用第三預設值的RAPID指示當前MAC subPDU為padding。 This method can reuse the MAC subheader format indication padding indicating RAR in the LTE system, and the E domain in the MAC subheader is no longer used, that is, the E domain in the MAC subheader is set to the R domain, that is, reserved bits. In this embodiment, the format of the MAC subheader indicating RAR is shown in FIG. 13, and the format of the MAC subheader indicating BI is shown in FIG. 14. This method can use the third preset value of RAPID to indicate that the current MAC subPDU is padding.

可選地，前述根據該MAC RAR PDU中的padding指示資訊，確定該MAC RAR PDU中的padding，包括：解析每個MAC subPDU的MAC子頭，並判斷每個MAC子頭中是否攜帶RAPID；若目標MAC subPDU的MAC子頭中攜帶RAPID，判斷該目標MAC subPDU的MAC子頭中攜帶的RAPID是否為第三預設值；若該目標MAC subPDU的MAC子頭中攜帶的RAPID為該第三預設值，確定該目標MAC subPDU為padding。 Optionally, determining the padding in the MAC RAR PDU according to the padding indication information in the MAC RAR PDU includes: parsing the MAC subheader of each MAC subPDU, and determining whether each MAC subheader carries RAPID; if The MAC subheader of the target MAC subPDU carries the RAPID, and determines whether the RAPID carried in the MAC subheader of the target MAC subPDU is the third preset value; if the RAPID carried in the MAC subheader of the target MAC subPDU is the third Set the value to determine that the target MAC subPDU is padding.

該實施例中，該方法利用MAC子頭中第三預設值(例如全0)的RAPID指示當前MAC subPDU為padding。具體地，該使用者設備解析每個MAC subPDU的MAC子頭，並判斷每個MAC子頭中是否攜帶RAPID；若目標MAC subPDU的MAC子頭中攜帶RAPID，說明該目標MAC subPDU的MAC子頭為帶RAR的MAC子頭或者MAC padding子頭；該使用者設備進一步判斷該目標MAC subPDU的MAC子頭中攜帶的RAPID是否為第三預設值，若該目標MAC subPDU的MAC子頭中攜帶的RAPID為該第三預設值，該使用者設備確定該目標MAC subPDU為padding；若該目標MAC subPDU的MAC子頭中攜帶的RAPID不為該第三預設值，該使用者設備確定該目標MAC subPDU的MAC子頭中攜帶的RAPID與隨機存取請求消息中的隨機存取前導序列對應，該MAC子頭後續跟隨的是MAC RAR。 In this embodiment, the method uses RAPID of the third preset value (for example, all 0s) in the MAC subheader to indicate that the current MAC subPDU is padding. Specifically, the user equipment parses the MAC subheader of each MAC subPDU, and determines whether each MAC subheader carries RAPID; if the MAC subheader of the target MAC subPDU carries RAPID, it indicates the MAC subheader of the target MAC subPDU Is a MAC sub-header with RAR or a MAC padding sub-header; the user equipment further determines whether the RAPID carried in the MAC sub-header of the target MAC subPDU is a third preset value, if the MAC sub-header of the target MAC subPDU carries RAPID is the third preset value, and the user equipment determines that the target MAC subPDU is padding; if the RAPID carried in the MAC subheader of the target MAC subPDU is not the third preset value, the user equipment determines the The RAPID carried in the MAC subheader of the target MAC subPDU corresponds to the random access preamble sequence in the random access request message. The MAC subheader is followed by the MAC RAR.
