[0036] 本发明涉及在所谓的长期演进(LTE)系统中的基站与移动终端之间交换数据。 [0036] The present invention relates to a so-called long term between Evolution (LTE) system, a base station and a mobile terminal to exchange data. 具体地说,在从各个逻辑信道接收到数据时构造MAC rou(或者诸如传输块的其它类型的数据单元)的MAC实体中,当MAC PDU中的填充空间可用时,移动终端利用MAC PDU的这种填充区域有效地发送缓冲区状态信息,从而使不必要的无线资源浪费最小化。 Specifically, the MAC entity configured MAC rou (or other types of transmission such as a data block unit) when data is received from each logical channel, the MAC PDU when filling the space available in the mobile terminal by using the MAC PDU which seed filling region efficiently transmit buffer status information, so that an unnecessary radio resource waste can be minimized.

[0037] 图1示出作为一种移动通信系统的E-UMTS(演进通用移动通信系统)100的示例性网络架构。 [0037] FIG 1 shows a mobile communication system as an E-UMTS (Evolved Universal Mobile Telecommunications System) 100 of exemplary network architecture.

[0040] 以下,将分别描述图2中的无线协议的控制面和图3中的无线协议的用户面。 [0040] Hereinafter, will be described separately in the user plane of the radio protocol 3 2 radio protocol control plane and FIG. FIG.

[0041] 在层1中,物理层225-245、325-345使用一个或者更多个物理信道来提供信息传送服务。 [0041] In Layer 1, the physical layer 225-245,325-345 using one or more physical channels to provide information transfer service. 物理层经由一个或者更多个传输信道连接到位于物理层上方的MAC (介质访问控制)层224-244、324-344,并且通过传输信道在MAC层和物理层之间传送数据。 The physical layer is connected via one or more transport channels to the physical layer positioned above the MAC (Media Access Control) layer 224-244,324-344, and transmitting data through the transmission channel between the MAC layer and the physical layer. 并且,在各个不同的物理层之间(诸如发射机(发送端)中的物理层和接收机(接收端)中的物理层),经由一个或者更多个物理信道来传送数据。 And, between the respective different physical layers (such as a transmitter (transmitting side) and the physical layer in the receiver (receive physical layer) side), via one or more physical channels to transmit data.

[0042] 在层2中,MAC层经由一个或者更多个逻辑信道来向作为高层的RLC (无线链路控制)层223-243、323-343提供服务。 [0042] In the layer 2, MAC layer via one or more logical channels to provide service to a high-level RLC (Radio Link Control) layer 223-243,323-343. RLC层支持可靠的数据传输。 The RLC layer supports reliable data transfer. 层2中的H)CP (分组数据汇聚协议)层322-342执行报头压缩功能,以便减小包含有相对较大且不必要的控制信息的互联网协议(IP :Internet Protocol)分组的报头尺寸,从而可以在带宽相对较小的无线接口上有效发送IP分组(诸如IPv4、IPv6等的IP分组)。 The layer 2 H) CP (Packet Data Convergence Protocol) layer 322-342 performs a header compression function to reduce an internet protocol comprising relatively large and unnecessary control information (IP: header size Internet Protocol) packet, It can be effectively transmitted over a relatively small bandwidth wireless interface IP packets (such as IPv4, IPv6 IP packets, etc.). 并且,PDCP层用于执行对控制面(C-plane :control plane)数据(诸如RRC消息)的编码。 And, PDCP layer for performing a control plane (C-plane: control plane) encoded data (such as a RRC message). PDCP层还执行对用户面(U-plane : user plane)数据的编码。 The PDCP layer also performs the user plane: encoding (U-plane user plane) data.

[0043] 位于层3最上部分的RRC (无线资源控制:Radio Resource Control)层222-242 仅定义在控制面中,并且RRC层负责与无线承载(RB)的配置、重新配置和释放相关联地对逻辑信道、传输信道和物理信道进行控制。 RRC (RRC: Radio Resource Control) [0043] 3 located on the uppermost portion of the layer 222-242 is only defined in the control plane, and the RRC layer is responsible for the radio bearer (RB) configuration, reconfiguration and release of association of logical channels, transport channels and the physical control channel. 此处,"无线承载"是由层2提供的、用来在移动终端和E-UTRAN之间传送数据的服务。 Here, "radio bearer" is provided by the layer 2, the service for communicating data between a mobile terminal and E-UTRAN.

[0044] 以下,将解释RACH (随机接入信道)的各个方面。 [0044] Hereinafter, will be explained various aspects of the RACH (Random Access Channel). RACH信道用来经由上行链路发送长度相对短的数据。 RACH channel for transmitting relatively short length data via the uplink. 具体地说,当存在要由没有接收到专用无线资源分配的移动终端通过上行链路而发送的信令消息或者用户数据时,使用RACH,或者,当基站应当指示移动终端执行RACH过程时,也使用RACH。 More specifically, when there is to be made when the signaling message is not received dedicated resource allocation of the mobile radio terminal transmits the uplink user data, or using RACH, or when the base station should instruct the mobile terminal to perform a RACH procedure when also use RACH.

[0045] 如上所述,构成E-UTRAN的两个主要部件是基站和移动终端。 [0045] As described above, two major components constituting the E-UTRAN are the base station and the mobile terminal. 单个小区的无线资源包括上行链路无线资源和下行链路无线资源。 Radio resources of a single cell include uplink radio resources and downlink radio resources. 基站负责分配和控制小区的上行链路无线资源和下行链路无线资源。 The base station responsible for the allocation and control of uplink radio resource of a cell, and downlink radio resources. 也就是说,基站确定由哪个移动终端在某时刻使用哪种无线资源。 In other words, the base station determines what radio resources by the mobile terminal which at some point. 例如,基站确定从现在开始的3. 2秒时,将从100MHz至101MHz的频率分配给用户1,持续0. 2秒,以用于下行数据传输。 For example, the base station determines that 3.2 seconds from now from the frequency from 100MHz to 101MHz is assigned to user 1 for 0.2 seconds, for downlink data transmission. 并且,在基站作出这种确定之后,可以将这些情况告知对应的移动终端,使得该移动终端接收下行数据。 Then, the base station after making such determination, these may inform the corresponding mobile terminal such that this mobile terminal receives downlink data. 类似地,基站可以确定某移动终端应当何时使用多少量的哪种无线资源来通过上行链路进行数据传输,并且基站将其确定告知移动终端,从而使得移动终端在所确定的时间段利用所确定的无线资源发送数据。 Similarly, the base station may determine whether a mobile terminal should be transmitted through the uplink data what amount of which radio resources when to use, and to inform the base station determines the mobile terminal, so that the mobile terminal using the determined period of time in determined radio resources to send data.

[0046] 如果基站以动态方式管理无线资源,则可以高效使用无线资源。 [0046] If the base station manages radio resources in a dynamic manner, efficient use of radio resources can. 通常,单个移动终端在呼叫连接期间连续使用单个无线资源。 Typically, a single mobile terminal continuously uses a single radio resource during a call connection. 考虑到最近的业务是基于IP分组的,这并不是优选的。 Taking into account recent business is based on IP packet, this is not preferred. 原因在于,多数分组业务在呼叫连接期间并不连续地生成分组,并且在呼叫期间很多时间段中不进行任何发送。 The reason is that most packet services do not continuously generate packets during a call connection, and does not perform any transmission period much during a call. 此外,将无线资源连续分配给单个移动终端是低效的。 In addition, radio resources are allocated to a continuous single mobile terminal is inefficient. 为解决该问题,E-UTRAN系统的移动终端使用了仅当存在业务数据时才向移动终端分配无线资源的方法。 To solve this problem, the mobile terminal E-UTRAN system uses a method when there is traffic data radio resources are allocated only to the mobile terminal.

[0047] 更详细地说,为了在LTE系统中高效使用无线资源,基站应当知道各个用户希望发送的数据类型和数据量。 [0047] More specifically, in order to efficiently use radio resources in the LTE system, each base station should know the type of data the user desires and amount of data transmitted. 下行数据是从接入网关传送给基站。 Downlink data from the access gateway to the base station. 因此,基站知道需要通过下行链路向各个用户传送多少数据。 Thus, the base station knows how much data needs to be transmitted to each user via the downlink. 相反,对于上行数据,如果移动终端本身并不将与通过上行链路传送的数据相关的信息告知基站,则基站不能得知各个移动终端需要多少无线资源。 Conversely, for uplink data, if the mobile terminal itself does not inform the base station through the uplink transmission data-related information, the base station can not know how radio resources of each mobile terminal needs. 因此,为了使基站将上行链路无线资源适当地分配给移动终端,各个移动终端应当向基站提供用于使得基站执行无线资源调度的必要信息。 Therefore, in order for the base station to appropriately uplink radio resource allocated to the mobile terminal, each mobile terminal should provide the necessary information for a base station that performs radio resource scheduling to the base station.

[0048] 为此,当移动终端有数据要发送时,将此情况告知基站,并且基站基于这种信息来向移动终端传送资源分配消息(或者使用一些其它的通知手段)。 [0048] For this reason, when the mobile terminal has data to send, inform this base station and the base station transmits information to the mobile terminal based on such a resource allocation message (or using some other notification means).

[0049] 在以上过程中,即,当移动终端有数据要发送时,当将这种情况告知基站时,移动终端将它的缓冲区中存储的数据量告知基站。 [0049] In the above process, i.e., when the mobile terminal has data to send, when such a base station inform the mobile terminal of the amount of data stored in the buffer it informs the base station. 这是通过缓冲区状态报告(BSR)或者一些其它缓冲区状态(或者状况(state))信息的方式来实现。 This is achieved through a buffer status report (BSR) or some other buffer status (or condition (state)) how the information.

[0050] 然而,以MAC控制元素(CE :control element)的形式生成缓冲区状态报告,该MAC 控制元素包含在MAC rou (协议数据单元)(或者一些其它类型的数据单元或传输块)中,并从移动终端发送到基站。 [0050] However, in a MAC control element (CE: control element) generated in the form of buffer status report, the MAC control element is included in the MAC ROU (Protocol Data Unit) (or some other type of a data unit or transport block), and transmitted from the base station to the mobile terminal. 也就是说,需要上行链路无线资源来发送缓冲区状态报告(BSR)。 In other words, we need to uplink radio resources to send the buffer status report (BSR). 这意味着需要发送针对发送BSR的上行链路无线资源分配请求信息。 This implies the need to send a request for information sent BSR uplink radio resource allocation. 当已经生成BSR时, 如果存在已经分配的上行链路无线资源,则移动终端立即使用该上行链路无线资源来发送BSR。 When a BSR has been generated, if the uplink radio resources already allocated exists, the mobile terminal immediately transmits the BSR to use uplink radio resource. 将这种从移动终端向基站发送BSR的过程称为"BSR过程"。 This process of transmitting the BSR from the mobile terminal to the base station is called "BSR procedure."

[0051] 以下,将参照图4至图8来解释MAC PDU结构,其中,图4至图8示出了由MAC实体(诸如图2中的224和244或者图3中的324、344)使用的各种示例MAC PDU格式。 [0051] Hereinafter, with reference to FIGS. 4 to 8 explain the structure of MAC PDU, in which FIG. 4 to FIG. 8 shows a MAC entity (such as 224 and 244 in FIG. 2 or 324, 344 in FIG. 3) using various examples of MAC PDU formats.

[0052] 图4示出由MAC实体使用的示例PDU格式。 [0052] FIG 4 illustrates an exemplary PDU format used by the MAC entity. LCID字段指示MAC SDU或者MAC控制元素(CE)是否与此相关。 LCID field indicates the MAC SDU or MAC control element (CE) is associated with this. 如果与MAC SDU有关,则这指示MAC SDU是属于哪个逻辑信道, 而如果与MAC CE相关,则这指示MAC CE的种类或类型。 If the related MAC SDU, this indicates that the logical channel is a MAC SDU belongs, and if the related MAC CE, the MAC CE indicates which kind or type. L字段告知关于MAC SDU的MAC SDU的大小。 L field informed about the size of a MAC SDU MAC SDU. E字段告知是否存在任何其它的MAC子报头。 E field informing whether there are any other MAC sub-header. 在上述过程中,如果对应的MAC SDU或者MAC CE的大小是127或者更小,则使用7比特的L字段,否则使用15比特的L字段(如图5所示)。 In the above process, if the corresponding MAC CE or MAC SDU size is 127 or less, using 7-bit L field, or using the L-bit field 15 (FIG. 5). 并且,MAC PDU中包含的MAC SDU位于MAC PDU中包含的数据字段的最后,并且使用如图6所示的相关MAC子报头。 And, MAC SDUs included in the MAC PDU on the last data field included in the MAC PDU, as shown in FIG. 6 and using the related MAC sub-header. 另选地,针对大小固定的MAC CE,则使用如图6所示的MAC子报头。 Alternatively, for a fixed size of the CE MAC, as shown in FIG. 6 using a MAC sub-header. 在其它情况中,使用如图5所示的MAC子报头。 In other cases, a MAC sub-header as shown in FIG. 5.

[0053] 图7和图8示出BSR报告的示例格式。 [0053] FIG. 7 and FIG. 8 shows an example format BSR reporting. 取决于具有数据的逻辑信道组的数量并且取决于MAC PDU中的可用空间大小,可以使用短BSR或长BSR。 It depends on the number of data having a logical channel group depends on the available space and the MAC PDU may use the short BSR or long BSR. 此处,短BSR和长BSR是指BSR的相对长度。 Here, the long and short BSR BSR is the relative length of the BSR. 因此,可以使用其它类似的术语来表示这种类型的BSR。 Thus, other similar terms to refer to this type of BSR. 例如,短BSR可以称为"截短的或缩短的BSR",长BSR可以称为"扩展的或延长的BSR"。 For example, the short BSR may be referred to as "truncated or shortened BSR" long BSR can be called "an extended or prolonged BSR."

[0054] 再次参照图4至图6,将解释图中使用的各个字段。 [0054] Referring again to FIG. 4 to FIG. 6, each field will be explained using FIG.

[0055] MAC报头具有可变大小,并由如下多个字段组成: [0055] MAC header having a variable size, by more of the following fields:

[0056] -LCID :逻辑信道ID字段,其针对DL-SCH和UL-SCH分别识别出对应的MAC SDU的逻辑信道实例、对应的MAC控制元素的类型、或者填充,如在表1和表2 (以下示出)中说明。 [0056] -LCID: Logical Channel ID field, which for the DL-SCH and UL-SCH are identified logical channel corresponding to the MAC SDU example, the type of the corresponding MAC control element or padding, as described in Table 1 and Table 2 (shown below) is described. 对于MAC PDU中包含的各个MAC SDU、MAC控制元素或者填充,都有1个LCID字段。 For each MAC SDU MAC PDU included, the MAC control element or padding, has a LCID field. 此外, 当需要单个字节或者两个字节的填充、但是不能通过在MAC PDU的结束处进行填充来实现时,MAC PDU中包含一个或者两个附加LCID字段。 Further, when a single byte or two bytes of padding required, but can not be filled at the end of the MAC PDU is achieved, MAC PDU contains one or two additional LCID field. LCID字段的大小是5比特; LCID field size is 5 bits;

[0057] -L:长度字段按照字节来指示对应的MAC SDU或MAC控制元素的长度。 [0057] -L: a length field indicating in bytes to the corresponding MAC SDU or MAC control element length. 除了最后一个子报头和与大小固定的MAC控制元素对应的子报头之外,针对每个MAC PDU子报头存在1个L字段。 Except for the last sub-header and a size of the MAC control element corresponding to the fixed sub-header addition, the presence of an L field for each MAC PDU subheader. 由F字段指示L字段的大小; L field size indicated by the field F;

[0058] -F :格式字段指示长度字段的大小。 [0058] -F: Size Format field indicates the length of the field. 除了最后一个子报头和与大小固定的MAC控制元素对应的子报头之外,针对每个MAC PDU子报头存在1个F字段。 Except for the last sub-header and a size of the MAC control element corresponding to the fixed sub-header addition, the presence of an F field for each MAC PDU subheader. F字段的大小是1比特。 Size F field is 1 bit. 如果MAC SDU或者MAC控制元素的大小小于128个字节,则UE应当将F字段的值设置为0,否则,UE应当将其设置为1 ; If the MAC SDU or MAC control element size is less than 128 bytes, the UE shall the value of the F field is set to 0, otherwise, the UE should be set to 1;

[0059] -E :扩展字段是指示MAC报头是否存在更多字段的标记。 [0059] -E: an extension field indicating whether or not MAC header exists more flag field. 将E字段设置为"1"来表示其它一组至少R/R/E/LCID字段。 The E field is set to "1" to indicate another set of at least R / R / E / LCID field. 将E字段设置为"0"来表示在下一个字节开始MAC SDU、MAC控制元素或者填充; The E field is set to "0" to indicate the next byte MAC SDU, MAC control element or padding;

[0060] -R:保留比特,设置为"0"。 [0060] -R: reserved bits set to "0."

[0069] 以下,将解释MAC实体构造MAC PDU的示例方法。 [0069] Hereinafter, will be explained an example constructed on MAC entity of the MAC PDU.

[0070] 当将多个无线承载(RB)复用到单个传输信道并进行发送时,(能够支持LTE的)移动终端中的MAC层使用关于针对各个传输时间给出的无线资源的如下规则,以便确定要发送的数据量。 [0070] When a plurality of radio bearer (RB) multiplexed in a single transport channel and transmitted, (LTE-capable) the MAC layer of the mobile terminal using the radio resources on the following rules for each given transmission time, and in order to determine the amount of data to be transmitted.

[0071] 1)首先,针对复用后的传输信道,基于各个逻辑信道的逻辑信道优先级(LCP: Logical Channel Priority)按照降序来确定传输数据量,并且根据所确定的数据量,利用逻辑信道的数据来构造MAC rou。 [0071] 1) First, the transport channels multiplexed, each based on logical channel priorities (LCP: Logical Channel Priority) is determined in descending order of data transfer amount, and the amount of data determined by the logical channel data to construct MAC rou.

[0072] 2)如果剩余了任何无线资源,则重复进行以上步骤1),使得对于所复用的传输信道,基于各个逻辑信道的逻辑信道优先级(LCP)按照降序来确定传输数据量。 [0072] 2) If any of the remaining radio resources, the above procedure is repeated 1), so that for the transport channel multiplexed based on a logical channel in descending order of each logical channel to determine the amount of data transmission priority (LCP).

[0073] 此处,当前讨论的LCP定义为从1到8,1是最高级而8是最低级。 [0073] Here, LCP define the current discussion is from 1 to 8,1 and 8 is the highest level is the lowest level. 然而,在将来讨论中可能改变具体的定义。 However, the specific definition may change in the future discussions. 并且,在上述过程中,如果需要发送任何MAC CE(控制元素),则首先将这种MAC CE包含在MAC PDU中。 In the above process, if any need to send MAC CE (Control Element), that the first MAC CE included in the MAC PDU.

[0074] 在以下多种情形中的至少一种中,移动终端可以执行对BSR过程的触发: [0074] at least one of the following in a variety of situations, the mobile terminal may perform the BSR procedure triggered:

[0075] a)初始时,全部缓冲区都不包含任何数据,但是当数据新近到达特定缓冲区时(常规的BSR); [0075] a) Initially, the entire buffer does not contain any data, but when the newly arrived data specific buffer (regular the BSR);

[0076] b)当数据到达空缓冲区,并且,与该缓冲区相关的逻辑信道的优先级高于之前在该缓冲区中具有数据的逻辑信道的优先级时(常规的BSR); When [0076] b) When data arrives empty buffer, and the buffer associated with the previous priority logical channel having a higher priority logical channel data in the buffer (the BSR normal);

[0077] c)当小区改变时(常规的BSR); [0077] c) when a cell change (normal the BSR);

[0078] d)在BSR的最后一次传输之后过去了特定时间时(周期性的BSR);以及 [0078] d) when a certain time elapsed (periodic BSR after the last transmission of a BSR); and

[0079] e)如果在所构造的MAC PDU中剩余了任何可用的空间(填充式BSR)。 [0079] e) If any of the remaining available space (filled BSR) in the constructed MAC PDU.

[0080] 在上述触发情况中,如果由于最后一种情形导致触发BSR,则将这样的BSR称为填充式BSR。 [0080] In the case triggered, if the last scenario due to the BSR triggering cause, this will be referred to as a BSR BSR filled. 移动终端根据从基站分配的无线资源量,即,根据MAC PDU的大小来构造MAC rou。 The wireless mobile terminal resource allocation from the base station, i.e., depending on the size of the MAC PDU constructed MAC rou. 此处,针对为移动终端建立的各个逻辑信道,移动终端的MAC实体将在逻辑信道的(多个)缓冲区中存储的数据依次包含(或者插入)到MAC PDU中。 Here, for each logical channel established by the mobile terminal, the MAC entity of the mobile terminal in turn comprises a MAC PDU (or inserted) in the data (s) stored in the buffer of the logical channel. 如果即使已经包含(插入)了关于各个逻辑信道存储的全部数据,MAC PDU中仍然剩余了任何可用空间时,则触发BSR过程,并且,将因此触发的填充式BSR包含到MAC PDU中用于进行构造,并将其发送给基站。 Even if already contains (inserted) on the entire data stored in each logical channel, the MAC PDU is still any remaining available space, the BSR procedure is triggered, and the thus-filled triggered BSR included for the MAC PDU configuration, and transmits it to the base station.

[0081] 然而,在某些情形中,由于填充而产生的BSR位于MAC PDU的最后部分。 [0081] However, in some cases, since filling the BSR is generated on the last portion of the MAC PDU. 也就是说, 在MAC实体利用各个逻辑信道的数据构造了MAC PDU之后,如果MAC PDU中剩余了任何空间,则在MAC PDU后部另外包含(插入)BSR。 That is, after the MAC entity data of each logical channel is configured using the MAC PDU, the MAC PDU if any remaining space, additionally comprising (insertion) at the rear of the BSR MAC PDU. 这在图9中示出。 This is illustrated in FIG.

[0082] 在图9中,假设移动终端从基站接收到用来构造大小为X+N个字节的MAC PDU的无线资源分配。 [0082] In FIG. 9, it is assumed the mobile terminal receives from the base station to allocate a radio resource configuration X + N bytes of the MAC PDU size. 此处,基于关于各个逻辑信道存储的数据,MAC实体开始填充MAC PDU用于进行构造。 Here, based on the data stored in each logical channel, the MAC entity begins to fill the MAC PDU used for construction. 在图9中,图9 (a)示出当由MAC实体利用其缓冲区中存储的全部数据来构造MAC PDU时发生填充的情况。 In FIG. 9, FIG. 9 (a) shows a case where the filling occurs when the MAC entity with its entire data stored in the buffer to construct MAC PDU. 如果填充的大小大于BSR的大小,则MAC实体将BSR加入填充区域。 If the size is larger than the size of padding BSR, the BSR MAC entity adding stuffing region.

[0083] 此处,从图9可见,由于没有向接收MAC PDU的接收机告知由于进行填充而包含了填充式BSR这一情况,所以该接收机不能有效使用BSR信息。 [0083] Here, seen from FIG. 9, since the received MAC PDU does not inform the receiver as a result of the filling includes filling the formula BSR this situation, so that the receiver can not effectively use the BSR information. 也就是说,该接收机不能得知已经接收到图9中的(a)或(b)的MAC PDU格式中的哪一个,因而即使MAC PDU包含BSR, 基站也不能利用该BSR信息来执行适当的无线资源分配。 That is, the receiver has not received that in FIG. 9 (a) or (b) a MAC PDU format in which, even if the MAC PDU contains the BSR, the BSR the base station can not use the information to perform the appropriate the radio resource allocation.

[0084] 并且,在某些情形中,为了发送填充式BSR,针对MAC PDU中包含的用户数据量的缩减,可能存在一些问题。 [0084] and, in some cases, in order to transmit the BSR filled, for reducing the amount of user data included in the MAC PDU, there may be some problems.

[0085] 图10示出移动终端接收到构造大小为L+M+3个字节的MAC PDU的指令的示例。 [0085] FIG. 10 shows the mobile terminal receiving a sample whose size is L + M + 3 bytes of the MAC PDU command. 在图10中,指示为剩余空间的部分是填充区域,并且示出其长度为2个字节。 In FIG. 10, indicated as part of the remaining space is filled region, and shows a length of 2 bytes. 此处,由于短BSR是1个字节,所以移动终端确定能够将短BSR插入到剩余空间中,因此,触发填充式BSR。 Here, since the short BSR is one byte, the mobile terminal determines that the short BSR can be inserted into the remaining space, therefore, fill-triggered BSR. 然而,当MAC实体试图插入短填充式BSR时,出现问题。 However, when the MAC entity trying to insert the BSR filled short, a problem occurs. 例如,从图10可见,RLC H)UN的MAC子报头中不包含L字段。 For example, seen from FIG. 10, RLC H) UN a MAC sub-header does not include the L field. 但是,如果在上述过程中当要插入填充式BSR时,则RLC H)UN将不再是MAC PDU中包含的最后一个元素。 However, if the above-described process when filled to insert the BSR, the RLC H) UN last element will no longer be included in the MAC PDU. 因此,在某些情形中,在不是最后一个元素的MAC SDU的MAC子报头中必须包含L字段。 Thus, in some cases, the MAC subheader of MAC SDU is not the last element must be included in the L field. 因此,由于强制插入填充式BSR,可能发生如下错误。 Thus, the forced insertion BSR filled, the following error may occur.

[0086] 也就是说,从图11可见,在剩余空间的2个字节中,1个字节用于填充式BSR,而MAC子报头仅有1个字节用于附加用途。 [0086] That is, seen from FIG. 11, the remaining space in the 2 bytes, one byte for the BSR filled, but only one MAC sub-header bytes for additional uses. 然而,如果RLC H)UN需要2个字节的L字段,则发生错误。 However, if the RLC H) UN requires 2 bytes L field, an error occurs. 因此,为了构造合适的MAC子报头,需要去除RLC PDU的1个字节部分。 Accordingly, in order to construct the appropriate MAC sub-header, one byte is necessary to remove part of the RLC PDU.

[0087] 本发明提供了当触发填充式BSR时由MAC实体用来以有效的方式将填充式BSR包含或插入到MAC PDU中的具体过程和规则。 [0087] The present invention provides a BSR when a triggering filled type used by the MAC entity in an efficient manner comprising BSR filled or inserted into specific rules and processes the MAC PDU. 以下将描述本发明的各种示例实施方式。 Various exemplary embodiments of the present invention will be described below.

[0088] 第一实施方式 [0088] First Embodiment

[0089] 将填充式BSR包含(或插入)到并非MAC PDU的最后部分的位置处。 [0089] The filled BSR comprises (or inserted) to a position not the last portion of the MAC PDU. 当触发填充BSR过程时,可将填充式BSR插入到在MAD PDU的MAC SDU或MAC CE之中的最后一个位置的前一位置处。 When triggering a padding BSR procedure, the filled BSR may be inserted into a position preceding the last position in the MAD PDU or MAC SDU in the MAC CE. 因此,可以按照同样的次序来设置与MAC SDU、MAC CE和填充式BSR相关的MAC子报头。 Thus, in the same order, to be provided with MAC SDU, MAC CE, and filled associated BSR MAC sub-header. 当触发填充BSR过程时,可将填充式BSR包含(或者插入)到MAC PDU的其它MAC SDU的前面。 When triggering a padding BSR procedure, the filled BSR may be included (or inserted) in front of the other MAC SDU is a MAC PDU. 因此,还可以按照同样的次序来设置与填充式BSR相关的MAC子报头。 Thus, also in the same order, to be arranged associated with the filled BSR MAC sub-header. 当触发填充BSR过程时,可将填充式BSR包含(或者插入)到MAC PDU的其它MAC SDU的后面。 When triggering a padding BSR procedure, the filled BSR may be included (or inserted) into the MAC PDU behind the other MAC SDU. 因此,还可以按照同样的次序来设置与填充式BSR相关的MAC子报头。 Thus, also in the same order, to be arranged associated with the filled BSR MAC sub-header.

[0090] 当构造MAC PDU时,在使用MAC SDU、MAC CE以及它们相关的MAC子报头填入MAC PDU之后,如果存在大小至少等于短BSR、长BSR和它们的MAC子报头的总和的任何剩余空间,则将短BSR、长BSR和它们的MAC子报头包含(或者插入)到MAC H)U。 [0090] When the configured MAC PDU, after use MAC SDU, MAC CE and their associated MAC sub-header filled MAC PDU, if the size of the presence of at least equal to the short BSR, any remaining sum of the long BSR, and their MAC sub-header space, then the short BSR, long BSR, and their MAC subheader containing (or inserted) into the MAC H) U. 在此过程中,可将MAC填充式BSR包含在MAC PDU的MAC SDU或者MAC CE的前面。 In this process, MAC-filled BSR may be included in front of the MAC PDU in the MAC SDU or MAC CE. 可将与MAC填充式BSR相关的MAC子报头包含在MAC PDU的全部MAC子报头的最前面。 It may be associated with the type of the BSR MAC padding MAC subheader included in the MAC sub-header entire front of the MAC PDU.

[0091] 本发明提出,在触发填充式BSR时,MAC实体考虑与其相关的MAC子报头的大小。 [0091] The present invention provides, upon triggering the BSR filled, consider the size of the MAC entity associated with a MAC sub-header. 也就是说,在构造MAC PDU时,MAC实体考虑MAC PDU是否有任何填充空间,以考虑到BSR的大小和它的相关子报头的大小。 That is, when constructing the MAC PDU, the MAC entity to consider whether there is any MAC PDU filling space, in order to take into account the size of the BSR and the size of its associated sub-header. 例如,如果短BSR大小是1个字节、且其相关子报头大小也是1个字节,则也考虑此子报头的大小,从而仅当MAC PDU的剩余空间是2个字节或者更多个字节时才触发BSR过程(短BSR)。 For example, if the short BSR size is 1 byte, and its associated sub-header size is 1 byte, it is also considered the size of this sub-header, so that only when the remaining space of the MAC PDU is 2 bytes or more BSR procedure is triggered when byte (short BSR). 并且,在此情况中,仅当能够适当构造其它MAC SDU和MAC CE的子报头时,才触发填充式BSR。 And, in this case, only when the other can be suitably configured MAC SDU and the MAC CE subheader triggered only filled BSR. 此处,"适当的构造"是指以下情况:包括针对不需要L字段的MAC CE而言并不具有F/L字段的MAC子报头;包括针对除了MAC CE之外的其余MAC SDU而言或针对要求L字段的最后一个MAC SDU而言具有F/L字段的MAC子报头; 以及包括针对最后一个MAC SDU而言并不具有F/L字段的MAC子报头。 Here, "proper structure" refers to the following: L need not include fields for MAC CE in terms of not having a MAC subheader F / L field; include MAC SDU except for the remaining terms or MAC CE for the L field required for the last MAC SDU MAC sub-header having a F / L field; and including for the purposes of the last MAC SDU does not have a F / L field in the MAC sub-header.

[0092] 在上述过程中,在构造了MAC PDU之后,并且在当存在特定剩余空间时触发了填充式BSR之后,将BSR包含(插入)到MAC PDU中,并且认为这种BSR是常规的BSR。 After [0092] In the above process, after the construction of the MAC PDU, and the BSR triggered filled when there are certain free space, comprising the BSR (inserted) into the MAC PDU, and that this is a conventional BSR BSR . 因此,以与处理常规的BSR相同的方式来处理填充式BSR。 Therefore, in the conventional BSR treated in the same manner to handle the filled BSR. 也就是说,在此情况中,填充式BSR的位置构造限制与常规的BSR位置构造限制相同。 That is, in this case, the position filled configured to limit the BSR BSR is identical to the conventional configuration limit position.

[0093] 在上述过程中,当由于填充而触发填充BSR过程时,具体地说,当由于填充式BSR 而将短BSR包含在MAC PDU中时,短BSR包括与在针对该移动终端所建立的逻辑信道(具有缓冲数据)中具有最高优先级的逻辑信道相关的逻辑信道组的缓冲区信息。 [0093] In the above process, when the padding BSR is triggered due to the filling process, in particular, when filled due to the short BSR BSR is included in the MAC PDU, including in the short BSR for the mobile terminal to establish logical channel (having buffered data) buffer information having the highest priority logical channel to logical channel group.

[0094] 第二实施方式 [0094] Second Embodiment

[0095] 本发明提出,在由于填充而导致BSR触发时,LCID字段用来直接(或明确)告知包含在MAC PDU中的BSR,从而接收机能够方便地确定并得知BSR包含在MACPDU中这一情况(尤其当由于填充而导致将BSR包含在MAC PDU中时)。 [0095] The present invention proposes, in the result due to filling BSR triggering, the LCID field is used directly (or explicitly) contains the BSR inform the MAC PDU, so that the receiver can be easily included in the BSR determined and that in this MACPDU a case (particularly when filled due to the result contained in the BSR when the MAC PDU). 更具体地说,提出了使用MAC子报头来指示是否已经包含了BSR。 More specifically, it proposed to use a MAC sub-header contains an indication whether BSR.

[0096] 参照图12,图12 (a)示出当MAC PDU包含填充时,基于填充的大小,接收机能够知道已经包含了填充式BSR。 [0096] Referring to FIG. 12, FIG. 12 (a) shows when a MAC PDU comprising a padding, padding based on the size of the receiver can know that already contains filled BSR. 在图12 (b)中,即使由于填充而导致将BSR包含在MACPDU中时,将具有与所包含的BSR相关的一组LCID字段的MAC子报头插入到MAC PDU中,从而直接(或明确)告知存在BSR。 MAC subheader in FIG. 12 (b), even if the filling and cause the BSR included in when a MAC PDU, having a set of LCID field associated with BSR included inserted into the MAC PDU, so as to directly (or explicitly) BSR inform exist.

[0097] 根据本发明的其它方法,当BSR被包含在MAC PDU中时并且当对于MAC PDU存在填充时,接收机认为BSR是填充式BSR。 [0097] According to another method of the present invention, when a BSR is included in the MAC PDU and when padding exists for MAC PDU, the receiver that is filled BSR BSR.

[0098] 在上述过程中,当由于填充过程而导致填充式BSR触发时,并且结果,当将BSR包含在MAC PDU中时,可以将与所分配的LCID不同的单独的LCID指定为指示出是短BSR还是长BSR。 [0098] In the above process, when due to the filling process resulting filled BSR is triggered, and as a result, when a BSR is included in when MAC PDU, may be the LCID assigned different individual LCID assigned to indicate that a short or long BSR BSR. 也就是说,如果当由于填充而导致填充式BSR触发时将BSR包含在MAC PDU中, 则移动终端在与BSR相关的MAC子报头中设置LCID字段(该LCID字段是单独指定的)。 That is, if the result when filled since filling triggered BSR BSR is included in the MAC PDU, the mobile terminal sets LCID field (LCID field which is specified separately) associated with the BSR in a MAC sub-header.

[0100] 参照包括图13 (a)、(b)和(c)的图13,当根据本发明构造MAC PDU时,发送方(或者发送端)的MAC实体得到从各个逻辑信道传送来的数据以及MAC控制元素,将它们包含(填入或者插入)到MAC PDU中,并且,如果MAC PDU剩余了2个字节的空间,则这剩余空间用于处理填充式BSR。 [0100] Referring to FIG comprising 13 (a), (b) and FIG. (C) 13, when constructing the MAC PDU according to the present invention, a sender (or the sending end) obtained MAC entity data for each logical channel transmitted from the and a MAC control element, they contain (filled or inserted) into the MAC PDU, and if the remaining MAC PDU two bytes of space, which is used to process the remaining space filled BSR. 以下说明利用此概念的各种应用。 The following illustrates the use of various applications of this concept.

[0101] 在本发明中,当构造MAC PDU时,发送方的MAC实体得到从各个逻辑信道传送来的数据以及MAC控制元素(CE),将它们包含(填入或者插入)到MAC PDU中,并且,如果MAC H)U 剩余了2个字节的空间,则包含多个填充报头(各个填充报头长度为1个字节)来填入MAC PDU的剩余空间。 [0101] In the present invention, when constructing the MAC PDU, the MAC entity sender from the data obtained for each logical channel and transmitted to the MAC control element (the CE), which contains the (filled or inserted) into the MAC PDU, and, if the MAC H) U remaining two bytes of space, comprising a plurality of filling the header (header length of the individual packing 1 byte) to fill the remaining space of the MAC PDU.

[0102] 在本发明中,当构造MAC PDU时,发送方的MAC实体得到从各个逻辑信道传送来的数据以及MAC控制元素(CE),将它们包含(填入或者插入)到MAC PDU中,并且,如果MAC H)U 剩余了2个字节的空间,则填入这2个字节空间,使得将L字段包含在最后一个MAC子报头中。 [0102] In the present invention, when constructing the MAC PDU, the MAC entity sender from the data obtained for each logical channel and transmitted to the MAC control element (the CE), which contains the (filled or inserted) into the MAC PDU, and, if the MAC H) U remaining two bytes of space, it is filled with the two-byte space, so that the L field is included in the last MAC sub-header.

[0103] 在本发明中,当构造MAC PDU时,发送方的MAC实体得到从各个逻辑信道传送来的数据以及MAC控制元素(CE),将它们包含(填入或者插入)到MAC PDU中,并且,如果MAC PDU剩余了2个字节的空间,则包含填充式BSR (即,针对MAC子报头的1个字节的BSR)和1个字节的短BSR以便填入MAC PDU的剩余空间。 [0103] In the present invention, when constructing the MAC PDU, the MAC entity sender from the data obtained for each logical channel and transmitted to the MAC control element (the CE), which contains the (filled or inserted) into the MAC PDU, and, if the MAC PDU remaining two bytes of space, filled contains the BSR (i.e., for a byte MAC sub-header BSR) and the BSR 1 byte short to fill the remaining space of the MAC PDU .

[0104] 应当注意,还可以按照类似的方式针对任意数量字节(不仅具有2个字节而且具有诸如4个字节)的剩余空间的MAC PDU来执行上述过程。 MAC PDU [0104] It should be noted that, also for any number of bytes (2 bytes and not only has advantages such as 4 bytes) in a similar manner the remaining space to perform the above-described procedure.

[0106] 当基站构造MAC PDU并向移动终端发送MAC PDU时,如果在构造了MAC PDU之后生成填充空间,贝lj可在MAC PDU中包含定时对准的命令(即,TAC(timing alignment command) 命令)。 [0106] When the base station to the mobile terminal configured to transmit MAC PDU MAC PDU, if the configuration after the MAC PDU generation filling space lj shell may include timing alignment command in the MAC PDU (i.e., TAC (timing alignment command) command). 可由移动终端使用这种TAC命令来调整它在上行链路上的传输定时。 The mobile terminal may use the TAC command to adjust such that transmission on the uplink timing. 例如,当在构造了MAC PDU之后MAC PDU中剩余了2个字节,则基站可针对TAC命令的子报头分配1个字节,并针对TAC命令本身(TAC命令向移动终端提供定时指令以调整它在上行链路上的传输)分配另1个字节。 For example, when the remaining MAC PDU constructed in the MAC PDU after two bytes, then the base station may allocate a sub-header for a byte command TAC and TAC for the command itself (TAC command to the mobile terminal to provide the timing command to adjust the it is transmitted on the uplink) assignment another 1 byte. 并且,即使剩余了1个字节的填充空间,则基站并不包含相关的MAC 子报头,但是将TAC命令包含在MAC PDU中并进行发送。 Further, even if the remaining filling space of one byte, the base station does not include the associated MAC sub-header, it will be included in the TAC command and transmits a MAC PDU.

[0108] 如果移动终端确定了存在填充空间,并试图触发填充式BSR,则提供更准确的规贝1J,使得如果实际上不能将填充式BSR包含在MAC PDU中,则防止触发填充式BSR。 [0108] If the mobile terminal determines the presence of the filling space, and tries to trigger the BSR filled, provides a more accurate regulation 1J shell, so that if not actually contained in the filled BSR MAC PDU, filled triggered BSR is prevented. 因此在本发明中,当移动终端使用MAC CE和MAC SDU来构造MAC PDU时,移动终端通过获取填充字节的大小来检查剩余空间,其中,填充字节的大小是MAC PDU的大小减去MAC SDU、MAC CE 及它们的MAC子报头的大小总和。 Therefore, in the present invention, when the mobile terminal using the MAC SDU and the MAC CE to construct MAC PDU, the mobile terminal checks the remaining space by obtaining the size of padding bytes, wherein the stuffing byte size of the MAC PDU size minus MAC SDU, MAC CE, and the total size of their MAC sub-header. 在此计算中,针对MAC PDU中包含的最后一个元素(即, 最后一个MAC SDU),移动终端假设L字段包含在与该MAC SDU相关的MAC子报头中。 In this calculation, for the last element included in the MAC PDU (i.e., a last MAC SDU), the mobile terminal is assumed that L field included in the MAC sub-header is associated with the MAC SDU. 如果最后一个元素是MAC CE,并且如果这种MAC CE具有可变的大小,则移动终端假设L字段包含在与该MAC CE相关的MAC子报头中,并执行这种计算。 If the last element is a MAC CE, and if such MAC CE has a variable size, the mobile terminal is assumed that L field included in the MAC sub-header associated with the MAC CE, and performs this calculation. 也就是说,假设针对最后一个元素的MAC子报头是"R/R/E/LCID/F/L",并且计算针对该MAC PDU的填充比特的大小。 That is, assuming MAC sub-header for the last element is "R / R / E / LCID / F / L", and for calculating the size of the padding bits of the MAC PDU. 并且, 仅当填充字节大小等于或大于BSR的大小与它的相关MAC子报头的大小总和时,才触发填充式BSR。 And, only when the sum of the relevant MAC sub-header size stuffing byte size or larger than the size of the BSR and it is triggered only filled BSR.

[0109] 也就是说,当计算填充字节量时,在此计算中包含与MAC PDU中包含的全部MAC SDU相关的(多个)MAC子报头中的(多个)F/L字段。 [0109] That is, when calculating the amount of stuffing bytes, is included in this calculation (s) of the MAC subheader (s) F / L field associated with all the MAC PDUs containing SDUs of the MAC in. 此处,即使对于具有可变大小的MAC CE,也通过在计算中包含与MAC CE相关的MAC子报头中的F/L字段来进行计算。 Here, even for MAC CE has a variable size, but also by including related MAC sub-header in the MAC CE F / L field to be calculated in the calculation. 因此,仅当填充字节数等于或大于BSR及与其相关的MAC子报头之和时,才触发填充式BSR。 Thus, only when the number of stuffing bytes equal to or greater and associated BSR MAC subheader sum filled only triggered BSR.

[0111] 参照包括图14 (a)和(b)的图14及包括图15 (a)、(b)和(c)的图15,当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果MAC PDU中有2个字节的剩余空间,并且如果MAC PDU中已经包含了短BSR,则本发明提出,利用长BSR来替换短BSR。 [0111] Referring to FIG comprising 14 (a) and FIG. (B) of FIG. 14 and 15 comprising (A), (b) and (c) of FIG. 15, when the configuration of MAC PDUs, the transmitter (transmitting side) of the MAC entity in the MAC PDU of each logical channel is filled from the data and the MAC CE, the MAC PDU if there is space remaining 2 bytes, and if the MAC PDU has been included short BSR, the present invention proposes to use long BSR replace short BSR. 因此如图14所示,在MAC PDU中包含长BSR而不是短BSR。 14 Thus, in the long BSR MAC PDU contains not short BSR.

[0112] 并且,当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果MAC PDU中有4个字节的剩余空间,这4个字节的剩余空间用于填充式BSR,具体地说,使用长BSR。 [0112] Further, when the MAC PDU is configured, the transmitter (transmitting side) and a MAC entity MAC CE fill data from each logical channel, if 4 bytes remaining space of the MAC PDU in the MAC PDU, which 4 bytes of the remaining space filled for the BSR, specifically, a long BSR. 此处,这4个字节包括1个字节MAC子报头、1 个字节短BSR以及2个字节用于填充。 Here, 4 bytes including 1-byte MAC sub-header, 1-byte and 2-byte short BSR for filling.

[0113] 当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果MAC PDU已经包含BSR,则如果MAC PDU中还有任何剩余空间, 还可将一个或者更多个其它BSR插入到MAC PDU中。 [0113] When the MAC PDU is configured, the transmitter (transmitting side) of the fill data from the MAC entity and a MAC CE for each logical channel in the MAC PDU, if already contains the BSR MAC PDU, the MAC PDU if there are any remaining space, one or more may also be inserted into other BSR MAC PDU.

[0114] 并且,当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果MAC PDU已经包含BSR,并且如果MAC PDU中还有任何剩余空间,则不触发填充式BSR。 [0114] Further, when the MAC PDU is configured, the transmitter (transmitting side) of the fill data from the MAC entity and a MAC CE for each logical channel in the MAC PDU, if already contains the BSR MAC PDU, and the MAC PDU if there any remaining space filled BSR is not triggered.

[0115] 此外,当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果MAC PDU中还有任何剩余空间,并且如果已经触发周期性的BSR或常规的BSR,则在最大尺寸的填充式BSR和已经触发的BSR中,仅插入最大的BSR。 [0115] Further, when constructing a MAC PDU, the transmitter (transmitting side) from the MAC entity data of each logical channel is filled, and the MAC PDU in the MAC CE, the MAC PDU if there is any space left, and if the trigger has been the regular BSR or periodic BSR, then the maximum size of the filled and BSR has been triggered BSR, the BSR is inserted into only the largest.

[0116] 此外,当构造MAC PDU时,发射机(发送端)的MAC实体在MAC PDU中填入来自各个逻辑信道的数据以及MAC CE,如果已经触发周期性的BSR或常规的BSR,则不触发填充式BSR〇 [0116] Further, when constructing a MAC PDU, the transmitter (transmitting side) is filled MAC entity in the MAC PDU of each logical channel data from the MAC and the CE, if a periodic BSR has been triggered BSR or conventional, not trigger filled BSR〇

[0117] 关于本发明的效果,当移动终端构造MAC PDU时,如果MAC PDU中存在任何剩余空间,则提供一种有效使用这种剩余空间的方法,以便提高无线资源的可用性和效率。 [0117] With regard to the effect of the present invention, when the mobile terminal is configured MAC PDU, if there is any space remaining in the MAC PDU, provides an effective method for using such a free space, in order to improve the availability and efficiency of radio resources.

[0118] 以下将解释有关本发明的概念和特征的更多细节。 [0118] Here will be explained more details about the concepts and features of the present invention.

[0119] 细节1 [0119] Details 1

[0120] 可以在MAC的最后一个子报头之前的其它地方(位置)包含填充式BSR。 [0120] Other places possible before header (position) comprises a filled BSR MAC in the last sub. 也就是说, 在传输块(TB)中填入了子报头以及相关MAC SDU或者其它MAC控制元素之后,当填充具有2个字节大小时,包含2个字节的短BSR。 That is to say, populated short BSR and subheader other related MAC SDU or MAC control element after, when the filling with two bytes in size, contains 2 bytes in the transport block (TB) in. 例如,如果可以恰好地去除填充,则第一子报头是短BSR。 For example, if the filler can be precisely removed, the first sub-header is a short BSR.

[0121] 也就是说,在TB中填入了子报头以及相关MAC SDU或者其它MAC控制元素之后, 当填充具有2个字节长度时,MAC SDU的最后一个子报头可包括2个字节的"L"字段。 After [0121] That is to say, populated subheader other related MAC SDU or MAC control element in the TB, when the filling has a length of 2 bytes, the last MAC SDU subheader may include a 2-byte "L" field. 也就是说,可使用指示"长L"字段和" 15个比特L字段"的F字段。 That is, using the indicated "length L" field and the "15-bit L field," the F field. 在每次对MAC子报头解码时,当子报头大小和相关MAC控制元素或者相关MAC SDU的大小的总和正好等于TB时(假设排除拖尾的1-7个比特),接收MAC实体认为不再有子报头。 When each of the MAC sub-header decoding, when the sub-header size and MAC control element associated or related to the total size of the MAC SDU exactly equal to the TB (assuming negative trailing bits 1-7), no longer receives a MAC entity that there are sub-header. 并不将此情况视为错误的情况。 This situation is not regarded as error. 也就是说,如果无需填充字节/LCID即可正好适配TB,则最后一个MAC子报头包括"L" 字段。 That is, if without the stuffing byte / LCID exactly adapted to TB, the last MAC sub-header includes a "L" field.

[0122] 细节2 [0122] Details 2

[0123] 除了要求单个字节或者两个字节的填充、但是不能通过在MAC PDU的结束处进行填充来实现时之外,在MAC PDU的结束处进行填充。 Addition [0123] In addition to a single byte or two bytes of padding required, but can not be filled at the end of the MAC PDU is achieved when, at the end of filling the MAC PDU.

[0124] 当需要单个字节或者两个字节的填充、但是不能通过在MAC PDU的结束处进行填充来实现时,在与MAC SDU相对应的第一个MAC PDU子报头之前插入与填充相对应的一个或者两个MAC PDU子报头;或者,如果不存在这种子报头,则在与MAC控制元素相对应的最后一个MAC PDU子报头之前插入与填充相对应的一个或者两个MAC PDU子报头。 When [0124] When filling a single byte or two bytes required, but can not be filled at the end of the MAC PDU is achieved, before the insertion filled with the first MAC SDU corresponding to a MAC PDU subheader one or both of the corresponding MAC PDU subheader; or, if such sub-header does not exist, is inserted before the last one MAC PDU sub-headers and MAC control element corresponding to the one or two MAC PDU sub-header filling corresponding .

[0125] 对于FDD,当数据加上报头的大小小于或等于由UE选择的E-TFC的TB大小减去24比特(这是由于能够被支持的传输块大小中的量化或者调度信息的触发而导致)时,应当在MAC-e报头的结束处附加DDI值[111 111],并且应当将调度信息串接到该MAC-e PDU中, 其中,DDI值[111111]表示该MAC-e PDU中串接了调度信息。 [0125] For FDD, the data plus header when the size is less than or equal to the TB size selected by the UE E-TFC subtracting 24 bits (This is because the transport block size that can be supported in the quantization of the trigger information or scheduling when lead), should additional DDI value in the MAC-e header at the end of [111 111], and it should be concatenated scheduling information to the MAC-e PDU in which, DDI value [111111] indicates the MAC-e PDU in series with the scheduling information. 否则,如果该数据加上报头的大小小于或等于由UE选择的E-TFC的TB大小减去18比特时,应当将调度信息串接到该MAC-e PDU中。 Otherwise, if the data is the header plus the size equal to or smaller than selected by the UE E-TFC size minus the 18 bits of the TB, it should be concatenated scheduling information to the MAC-e PDU in. 在任何其它情况中,认为其它MAC-es PDU或者调度信息不适配,因此,不需要在传输块中为额外的DDI字段保留空间。 In any other case, that other MAC-es PDU or not adapted to the scheduling information, there is no need for the additional DDI field reserves space in the transport block.

[0126] 也就是说,在HSUPA的情况下,为了确定包含什么内容或者何时停止填入MAC TB, 发射机持续对MAC报头加上MAC数据的大小与可用的传输块大小进行比较,这样,在一些情况中,可加入调度信息而无需指示存在调度信息的任何字段。 [0126] That is, in the case of HSUPA, comprising in order to determine when to stop the fill or what the TB MAC, the MAC transmitter Length header plus the size of the MAC data is compared with the available transport block sizes, so that, in some cases, the scheduling information may be added without any field indicates the presence of the scheduling information. 因此,可以省略诸如DDI的一些报头字段,从而提高效率。 Accordingly, such a number may be omitted DDI header field, thereby improving efficiency.

[0127] 但是,当前的LTE MAC规范并没有说明这类操作。 [0127] However, the current LTE MAC specification does not specify such operations. 因此,针对是否禁止HSUPA操作, 出现了问题。 Therefore, whether the prohibition against HSUPA operation, there is a problem. 图13示出了该问题。 FIG 13 illustrates this problem.

[0128] 在图13 (a)中,由于包含2个填充子报头而耗尽了剩余的两个字节。 [0128] In FIG. 13 (a), because it contains two padding subheader depleted remaining two bytes. 在图13 (b) 中,用"F"和"L"字段来替代这两个字节。 In FIG 13 (b), with "F" and "L" field instead of two bytes. 因此,最后一个子报头还包括"F"和"L"字段。 Thus, the last subheader further comprises a "F" and "L" field. HSUPA中也采用类似方法。 HSUPA is also similar method. 也就是说,通过对子报头加上数据字段的总和与传输块(TB)的大小进行比较,接收机能够得知没有填充。 That is, the header plus sub-data field is the sum of the size of the transport block (TB) are compared, the receiver can know not filled. 在图13 (c)中,用短BSR替代这两个字节。 In FIG 13 (c), an alternative two-byte short BSR. 实际上,短BSR不是空的缓冲区状态报告。 In fact, the short BSR is not empty buffer status report. 在图16中示出对于图13 (c)有用的情形。 Shown in FIG. 16 to FIG useful in the case of 13 (c).

[0129] 如图16所示,填充LCID的存在不对UE的缓冲区中是否仍有数据进行区分。 As shown in [0129] 16, whether or not filled LCID still present in the data buffers of the UE to distinguish. 为了高效地辅助eNB调度器,认为图13中的方法(c)比方法(a)更好。 In order to efficiently assist the eNB scheduler, a method that in FIG. 13 (c) is better than the method (a). 也就是说,不是通过填充LCID而浪费2个字节,将这2个字节用于短BSR更有意义。 In other words, not wasting 2 bytes by padding LCID, these two bytes for more meaningful short BSR.

[0130] 再次参照图4至图6,将提供对MAC H)U (DL-SCH和UL-SCH)的解释。 [0130] Referring again to FIGS. 4 to 6, explanation will be provided to the MAC H) U (DL-SCH and UL-SCH) is.

[0131] MAC PDU包括MAC报头、零个或者更多个MAC业务数据单元(MAC SDU)、零个或者更多个MAC控制元素,并且可选地包括填充;如图4所示。 [0131] MAC PDU includes a MAC header, zero or more MAC service data units (MAC SDUs), zero or more MAC control elements, and optionally padding; 4. MAC报头和MAC SDU这两者都具有可变的大小。 Both the MAC header and the MAC SDU has a variable size. MAC PDU报头包括一个或者更多个MAC PDU子报头;各个子报头分别对应于MAC SDU、MAC控制元素或者填充。 MAC PDU header includes one or more MAC PDU sub-headers; each sub-header corresponding to a MAC SDU, MAC control element or padding. 在一些实施方式中,针对填充的MAC PDU子报头在MAC PDU中出现不应当多于一次。 In some embodiments, for filling the MAC PDU subheader in the MAC PDU should not be more than once.

[0132] 除了MAC PDU中的最后一个子报头和大小固定的MAC控制元素之外,MAC PDU子报头包括六个报头字段R/R/E/LCID/F/L。 [0132] except the last subheader in the MAC PDU size and a fixed MAC control element, MAC PDU subheader includes six header fields R / R / E / LCID / F / L. MAC PDU中的最后一个子报头和大小固定的MAC 控制元素的子报头仅包括四个报头字段R/R/E/LCID。 And last subheader in the MAC PDU size fixed MAC Control element includes only four sub-header header fields R / R / E / LCID. 随后,与填充相对应的MAC PDU子报头包括四个报头字段R/R/E/LCID。 Subsequently, the filling of the corresponding MAC PDU sub-header comprises four header fields R / R / E / LCID.

[0133] MAC PDU子报头具有与对应的MAC SDU、MAC控制元素和填充相同的次序。 [0133] MAC PDU sub-header having a sequence of elements corresponding to the same filling MAC SDU, MAC control. 除了填充式BSR之外,MAC控制元素始终设置在任何MAC SDU之前。 In addition to the filled BSR, MAC control element is always provided before any MAC SDU. 在MAC PDU的结束处进行填充式BSR。 BSR be filled at the end of the MAC PDU. 除了当要求单个字节、但是不能通过在MAC PDU的结束处进行填充来实现时,在MAC PDU的结束处进行填充。 Except when required single byte, but can not be filled at the end of the MAC PDU is achieved, at the end of filling the MAC PDU. 当要求单个字节、但是不能通过在MAC PDU的结束处进行填充来实现时,在与MAC SDU相对应的第一个MAC PDU子报头之前插入与填充相对应的一个MAC PDU子报头;或者,如果不存在这种子报头,则在与MAC控制元素相对应的最后一个MAC PDU子报头之前插入与填充相对应的一个MAC PDU子报头。 When you require a single byte, but can not be filled at the end of the MAC PDU is achieved, inserting the filling corresponding to one MAC PDU sub-header before the MAC SDU corresponding to the first MAC PDU subheader; or If such sub-header is not present, then the last MAC inserted prior to filling head corresponding PDU sub-header and a MAC control element corresponding to the MAC PDU sub-header. 在MAC PDU中填入MAC SDU或者MAC控制元素(除了BSR之外)之后当剩余两个字节时,则包含短BSR。 Fill MAC SDU in the MAC PDU or the MAC control elements (except BSR) Later, when the remaining two bytes, comprises a short BSR.

[0134] 在一些实施方式中,可以每UE每TB最多发送一个MAC H)U。 [0134] In some embodiments, it can send a MAC H) U Up per UE per TB. 并且,取决于物理层类别,可以每UE每TTI发送一个或者两个TB。 And, depending on the physical layer category can be transmitted per TTI of one or two TB per UE.

[0135] 应当注意,该MAC PDU仅适用于DL/UL SCH或者还适用于其它传输信道是FFS。 [0135] It should be noted that the MAC PDU only for DL ​​/ UL SCH or also applicable to other transmission channel is FFS.

[0136] 细节3 [0136] Details 3

[0137] 当MAC PDU中存在的特定剩余空间等于或者大于BSR的大小,则包含填充式BSR。 [0137] When the specific MAC PDU in the remaining space is equal to or greater than the present size of the BSR, the BSR comprising filled. 如果分配了上行链路(UL)资源并且填充比特数大于缓冲区状态报告MAC控制元素,则以下将这种BSR称为"填充式BSR"。 If (UL) resource allocation and uplink filler bits is greater than the buffer status report MAC control element, the BSR hereinafter this is called "BSR-filled." 但是,针对怎样表述填充式BSR,需要解决如下问题:MAC控制元素(除了填充式BSR之外)始终位于任何MAC SDU之前。 But for how expressions filled BSR, need to address the following issues: MAC control elements (except filled BSR) is always located before any MAC SDU. 除了当要求单个字节或者两个字节填充、但是不能通过在MAC PDU的结束处进行填充来实现时之外,在MAC PDU的结束处进行填充式BSR,并且在MAC PDU的结束处进行填充。 In addition to the single byte or two bytes when filled requirements, but can not be filled at the end of the MAC PDU is achieved when filling the formula BSR at the end of the MAC PDU, and is filled at the end of the MAC PDU . 填充式BSR和填充这两者都在MAC PDU的结束处进行。 BSR filled and the filling are carried out both at the end of the MAC PDU. 然而,是由BSR LCID明确地指示出填充式BSR还是由填充LCID隐含地指示出填充式BSR,或者是填充式BSR位于填充之后还是填充位于填充式BSR之后,这些都是通过本发明解决的一些问题。 However, by clearly BSR LCID indicating padding BSR formula or implicitly indicated by the LCID filled BSR-filled, or filled after the BSR is located after the filling or padding BSR located filled, which are solved by the present invention some problems.

[0138] 怎样指示填充式BSR (4个提议) [0138] indicating how filled BSR (4 a suggestion)

[0139] 图17示出如何指示出存在填充式BSR的两种可能的实现(参照图17 (a)和图17 (b))〇 [0139] FIG. 17 shows how indicates two possible implementations exist filled BSR (see FIGS. 17 (a) and 17 (B)) square

[0140] 在图17 (a)中,取决于填充区的大小,可包含短BSR或长BSR而无需相关子报头。 [0140] In FIG. 17 (a), depending on the size of the filled region, may comprise a short or long BSR BSR without the associated subheader. 在图17 (a)中,只要填充的大小等于或大于2个字节,即可包含BSR。 In FIG 17 (a), as long as the size of padding is greater than or equal to 2 bytes, it can contain BSR. 在此方法中,如果在MAC PDU中填入了(多个)其它子报头或MAC SDU/CE之后还剩余3个字节,则可包含BSR。 In this method, after it filled in if (s) in the MAC PDU sub-headers, or other MAC SDU / CE further remaining 3 bytes, can contain BSR.

[0141] 在图17(b)中,最后2个MAC子报头是BSR子报头和填充子报头,从而明确指不出填充式BSR。 [0141] In FIG. 17 (b), the last two sub-header is a MAC sub-header and padding BSR sub-header, so that no means clear filled BSR. 在图17 (b)的方法中,当在MAC PDU中填入了(多个)其它子报头或MAC SDU/ CE之后还剩余4个字节时,则可包含BSR。 In the method of FIG. 17 (b), when filled in after (s) in the MAC PDU sub-headers, or other MAC SDU / CE further remaining four bytes, it can contain BSR.

[0142] 也就是说,图17 (a)和图17 (b)两种方法之间的差异在于用于包含BSR的最小剩余字节数是多少。 [0142] That is, the difference between the two methods in FIG. 17 (a) and 17 (b) that a minimum number of remaining bytes contain the BSR is.

[0143] 提议1 [0143] 1 proposal

[0144] 提出了确定是使用明确的方法还是隐含的方法来指示填充式BSR,并且考虑填充式BSR和填充之间的次序。 [0144] proposed a method of determining whether to use explicit or implicit method to indicate a filled BSR, and considering the order filled between the BSR and padding.

[0145] 图17示出在如图12 (a)所示使用隐含指示的情况下关于填充式BSR的定位的两种可能的实现。 [0145] FIG. 17 shows a case where (a) indicates implicitly used as shown in FIG. 12 positioned on two kinds of filled BSR possible implementation. 任何一种方法都是有效的。 Either method is valid. 在图17中,可以理解,BSR可以设置在用于填充的字节之前或者之后。 In Figure 17, it is understood, the BSR can be set before or after the byte for filling.

[0146] 图18示出在如图12 (b)所示使用明确指示的情况下关于填充式BSR的定位的两种可能的实现。 [0146] FIG. 18 shows the case of FIG. 12 (b) using an explicit indication shown positioned on both the BSR filled possible implementation. 这两种解决方案都基于"E"字段。 Both solutions are based on the "E" field. 如果"E"字段指示其它MAC子报头,则接收机仅对下一个字节解码,以得知随后的是什么。 If the "E" field indicates other MAC sub-header, the receiver decodes the next byte only to know what a subsequent Yes. 但是,在方法(b)中,在检测到填充LCID 之后的BSR LCID时,eNB中的MAC接收机能够立即对最后一个字节解码,以得知UE的缓冲区状态。 However, in the method (b), when the BSR LCID LCID after detecting the filling, the eNB MAC receiver is able to immediately decode the last byte to know the buffer status of the UE. 另一方面,在方法(a)中,在检测到BSR LCID时,eNB中的MAC接收机在对BSR的第一个字节解码之前首先需要计算BSR的起始位置。 On the other hand, in the method (a), when the detected BSR LCID, MAC in eNB receiver before the first byte of a first BSR decoding start position needs to be calculated BSR.

[0147] 提议2 [0147] Proposal 2

[0148] 提出了确定在MAC PDU中填入BSR是最后一个还是填充是最后一个。 [0148] proposed fill BSR determined in the MAC PDU is the last one or the last one filled.

[0149] 提议3 [0149] Proposal 3

[0150] 当在MAC PDU中填入除了BSR的MAC SDU或者MAC CE之后还剩余2个字节时,应当使用这2个字节来传送短BSR。 [0150] In addition, when filled in after the BSR MAC SDU or MAC CE also remaining 2 bytes in the MAC PDU, it should be used to transmit the two-byte short BSR.

[0151] 同时,如果在已将BSR包含在MAC PDU中之后剩余了两个字节,则可以考虑图19 (在包含了短BSR之后剩余2个字节的情况)中的情形以及图20 (在明确的填充式BSR指示的情况中,在包含了长BSR之后剩余2个字节的情况)中的情形。 [0151] Meanwhile, if, after the BSR has been included in the MAC PDU remaining two bytes, consider FIG. 19 (remaining 2 bytes in the case of comprising after short BSR) in the case of FIG. 20 and ( in the case of explicit indication of filled BSR, long BSR comprises after the remaining cases 2 bytes) of the case.

[0152] 图19 (a)示出在已经将短BSR包含到MAC PDU中之后剩余2个字节的情况。 [0152] FIG. 19 (a) shows a case where the remaining 2 bytes after having been incorporated into the short BSR MAC PDU. 这种情况意味着在仅填入了来自各个逻辑信道的数据之后MAC PDU中最初剩余了4个字节。 This situation means that after only populated with data from the MAC PDU of each logical channel initially remaining 4 bytes. 换言之,在MAC PDU中填入了RCL PDU之后,在包含短BSR之前还有4个字节可用。 Other words, after filled in the RCL PDU in the MAC PDU, prior to short BSR comprises 4 bytes also available. 无论RLC实体中是否存在其它数据,这4个字节是初始填充字节。 Whether there are other data in the RLC entity, the initial four-byte stuffing bytes. 然后,应当包含长BSR而不是短BSR。 Then, it should contain long rather than short BSR BSR. 因此,应当使用图19 (b)而不是使用图19 (a)。 Thus, it should be used in FIG. 19 (b) instead of FIG. 19 (a).

[0153] 图20 (a)示出在已经包含长BSR之后剩余2个字节的情况。 [0153] FIG. 20 (a) shows a case where the remaining two bytes long after it has been comprising BSR. 这意味着在填入了来自各个逻辑信道的数据之后MAC PDU中最初剩余了6个字节。 This means that after each populated with data from the first logical channel of the MAC PDU remaining six bytes. 换言之,在MAC PDU中仅填入了来自上层的RCL PDU之后,还有6个字节可用。 Other words, after the MAC PDU only populated RCL PDU from the upper layer, there are six bytes available. 针对此情况,有三种情形: For this situation, there are three scenarios:

[0154] 1.如果各个RLC实体中没有剩余数据,则这6个字节是初始填充字节,应当取消该BSR,或者应当包含正常的填充式BSR。 [0154] 1. If the respective RLC entity no remaining data, then this is the initial six bytes of stuff bytes, the BSR should be canceled, or filled should contain normal BSR. 在此情况中,如果针对填充式BSR使用明确指示,则将采用图4中的(b)和(c)而不是(a)。 In this case, if an explicit indication for the BSR filled, then employed in FIG. 4 (b) and (c) but not (a). 如果针对填充式BSR使用隐含指示,则将采用图5 中的(b)和(c)而不是(a)。 If implicit indication for filled BSR, will be employed in FIG. 5 (b) and (c) but not (a).

[0155] 2.如果在填入了MAC PDU之后仅有一个逻辑信道具有数据,则必定已经触发了短BSR,并且剩余的4个字节必定用来包含该逻辑信道的数据。 [0155] 2. If there is only one logical channel data after having filled in the MAC PDU, it must have been triggered short BSR, and the remaining four bytes of data must be used to contain the logical channel.

[0156] 3.如果在填入了MAC PDU之后超过一个逻辑信道具有数据,则无论如何应当包含长BSR。 [0156] 3. If more than one logical channel is filled with data after the MAC PDU, it should include in any case the long BSR. 但是这种情形显得有些怪异,因为,在针对填充式BSR使用明确指示的情况下将采用图20 (b)和图20 (c)。 But this situation looks a little weird, because, in the case of clear instructions for the fill-in will use the BSR Figure 20 (b) and 20 (c). 并且,在针对填充式BSR使用隐含指示的情况下,将采用图21 (b)和图21 (c)(在隐含的填充式BSR指示的情况下,在包含长BSR之后剩余2个字节的情况)。 And, in the case where an implicit indication for the filled BSR, will be used in FIG. 21 (b) and 21 (c) (in the case of implicit filled BSR instruction, after the remaining words contain a long BSR 2 case section).

[0157] 因此,两个字节填充子报头的情况可能并不明显,并且并非始终有用。 [0157] Thus, where two sub-header bytes of padding may not be obvious, and not always helpful. 并且因为当前的MAC结构能够避免两个字节的填充,所以不应当存在两个字节的填充子报头。 And since the current MAC structure can prevent the filling of two bytes, so there should be no two-byte padding subheader.

[0158] 提议4 [0158] Proposal 4

[0159] 应当避免MAC报头内部的两个字节的填充子报头。 [0159] should be avoided in the interior of the two-byte MAC header padding subheader.

[0161] 对于该网络,可以按照如下方式描述本发明的一些概念: [0161] For the network, some concepts of the invention as follows:

[0162] eNB通过利用RLC/roCP缓冲区中对于一个UE可用的数据并且通过另外利用MAC 控制元素,来组成mac rou。 [0162] eNB by using mac rou RLC / roCP a buffer for data available to the UE and the control element by additionally using MAC, to the composition.

[0163] 在利用MAC SDU/MAC CE 填入了MAC PDU 之后: [0163] In use MAC SDU / MAC CE of the MAC PDU is filled after:

[0164] -如果在填入MAC PDU之后剩余两个字节, [0164] - If the remaining MAC PDU after fill two bytes,

[0165] -则eNB将定时对准命令(ΤΑ CMD)包含到MAC PDU中,替代该两个字节。 [0165] - then the eNB will Timing Alignment Command (ΤΑ CMD) included in the MAC PDU, instead of the two bytes.

[0166] 在此情况中,使用一个字节来包含TA CMD的子报头,以及 [0166] In this case, a sub-header comprising a TA CMD byte, and

[0167] --使用一个字节来包含定时命令的实际值。 [0167] - the use of a timing command byte contains the actual value.

[0168] -如果在填入MAC PDU之后剩余了超过两个字节, [0168] - If more than two bytes remaining after fill MAC PDU,

[0169] -贝lj eNB将TA CMD包含到MAC PDU中,替代该至少两个字节。 [0169] - the TA CMD shell lj eNB included in the MAC PDU, in place of the at least two bytes.

[0170] 在此情况中,使用一个字节来包含ΤΑ CMD的子报头,以及 [0170] In this case, the use of a sub-header byte containing ΤΑ CMD, and

[0171] --使用一个字节来包含定时命令的实际值。 [0171] - the use of a timing command byte contains the actual value.

[0172] -----并且使用至少一个字节作为针对填充的子报头。 [0172] ----- and using at least one byte as a sub-header for filling.

[0173] -或者,如果在填入MAC PDU之后剩余了超过两个字节, [0173] - or, if more than two bytes remaining after fill MAC PDU,

[0174] -贝lj eNB将TA CMD包含到MAC PDU中,替代该至少两个字节。 [0174] - the TA CMD shell lj eNB included in the MAC PDU, in place of the at least two bytes.

[0177] -----并且使用其它多个字节作为填充。 [0177] ----- and other filler as a plurality of bytes.

[0178] 或者,用TA CMD替换一个字节的填充。 [0178] or, alternatively filled with a byte TA CMD.

[0179] 对于该移动终端,可以按照如下方式描述本发明的特定概念: [0179] for the mobile terminal, the present invention may describe a particular concept is as follows:

[0180] UE将所接收的MAC PDU解码/重新打包为MAC SDU和/或MAC CE。 [0180] UE will decode the received MAC PDU / repackage the MAC SDU and / or a MAC CE.

[0181] -UE对各个子报头以及与该子报头相关联的MAC SDU/CE解码 [0181] -UE of each MAC SDU and the sub-header and associated subheader / CE decoding

[0182] -UE计算子报头和MAC SDU/CE的大小总和 [0182] -UE calculation sub-header and MAC SDU / CE the sum of the size of

[0183] -UE将该大小总和与MAC PDU的大小相比较 [0183] -UE compared with the total size of the MAC PDU size

[0184] -如果指示出填充并且填充的大小(除了填充子报头之外)等于或大于1个字节, [0184] - indicates that the filling and filling if the size (outside except padding subheader) is equal to or greater than 1 byte,

[0185] -则UE认为TA CMD包含在填充部分之中。 [0185] - the UE considers TA CMD included in the filling portion.

[0186] 细节5 [0186] Details 5

[0187] 针对上行方向,当前的MAC规范要求,如果填充空间允许包含BSR,则UE应当包含BSR。 [0187] For the upstream direction, the current MAC specification requirements, if space permits filling comprises the BSR, the UE shall comprise BSR. 考虑到需要两个字节来包含短BSR,则只要剩余填充空间为两个字节,就将BSR包含在MAC PDU 中。 Considering the need to include two bytes short BSR, as long as the remaining filling space of two bytes, it will be included in the BSR MAC PDU.

[0188] 在图22中,由于2个字节足够包含短BSR,将不会发生图22 (a)的情形。 [0188] In FIG. 22, since 2 bytes short enough to contain the BSR, will not be the case in FIG. 22 (a) occurs. 如果我们遵照当前规范的意图,则UE应当发送图22 (b)的格式。 If we follow the current intent specification, the UE should send Figure 22 (b) format.

[0189] 因此,不需要根据以下说明的对两个字节的填充进行特殊处理: [0189] Thus, no special treatment in accordance with the filling of two bytes described below:

[0190] 除了要求单个字节或者两个字节的填充、但是不能通过在MAC PDU的结束处进行填充来实现时之外,在MAC PDU的结束处进行填充。 Addition [0190] In addition to a single byte or two bytes of padding required, but can not be filled at the end of the MAC PDU is achieved when, at the end of filling the MAC PDU. 当需要单个字节或者两个字节的填充、 但是不能通过在MAC PDU的结束处进行填充来实现时,在与MAC SDU相对应的第一个MAC PDU子报头之前插入与填充相对应的一个或者两个MAC PDU子报头;或者,如果不存在这种子报头,则在与MAC控制元素相对应的最后一个MAC PDU子报头之前插入与填充相对应的一个或者两个MAC PDU子报头。 When a single byte or two bytes of padding required, but can not be filled at the end of the MAC PDU is achieved, corresponding to the filling inserted before a MAC SDU corresponding to the first MAC PDU subheader or two MAC PDU sub-header; or, if such sub-header is not present, then a MAC control element corresponding to the last MAC inserted padding corresponding previous header PDU subheader one or two MAC PDU sub-header.

[0191] 顺便提到,图22 (b)中的BSR可以称为填充式BSR,因为该BSR是由于填充空间而被包含。 [0191] Incidentally, FIG. 22 BSR (b) may be referred to as a filled BSR, the BSR is because due to the filling space is included. 因为BSR不位于MAC PDU的结束处,可能会有争议,这与填充式BSR的当前定义不一致。 Because the BSR is not located at the end of the MAC PDU may be controversial, it is inconsistent with the current definition filled BSR. 然而,填充式BSR不必是MAC PDU中的最后一个元素。 However, not necessarily filled BSR is the last element in the MAC PDU. 此外,利用明确的LCID来指示填充式BSR。 In addition, the use of explicit LCID to indicate filled BSR. 因此,填充式BSR可以位于MAC PDU内部的任何位置处。 Thus, fill-in BSR can be located at any position within the MAC PDU.

[0192] 在下行方向中,不需要BSR,DL中的情形不同于UL。 [0192] In the downstream direction, no BSR, DL is different from the case of UL. 因此,在DL方向中仍然要求对2个字节填充的特殊处理。 Thus, in the DL still require special handling in the direction of two-byte padding. 因为定时提前命令的大小是2个字节,所以可能会有争议,只要MAC PDU中剩余2个字节就可以包含TA CMD。 Since the size of the timing advance command is 2 bytes, it may be controversial, as long as the remaining MAC PDU can comprise 2 bytes TA CMD. 发送更多个TA CMD是有益的,因为,这能够更久地将UE保持在同步状态中,但是这不必要地限制了eNB的动作。 Send more TA CMD is beneficial because it can longer be kept in sync the UE state, but this is unnecessarily restrict the movement of the eNB.

[0193] 关于进一步分析,为了安全起见,我们还需要考虑针对已经包含了BSR的MAC H)U 剩余2个字节的情况。 [0193] For further analysis, for safety reasons, we also need to consider for already contains the BSR MAC H) U where the remaining 2 bytes. 以下图23中针对短BSR示出这种情况,图24中针对长BSR示出这种情况。 The following Figure 23 shows for this case the short BSR, long BSR in FIG. 24 for the case shown.

[0194] 也就是说,如果对于已经包含了短BSR的MAC PDU还剩余2个字节,则这意味着对于BSR有4个字节可用。 [0194] That is, if for already contains short BSR MAC PDU is also remaining 2 bytes, then this means that there are four bytes available BSR. 那么,长BSR将取代短BSR。 So long BSR will replace the short BSR. 因此,将采用图23 (b)而不是图23 (a)〇 Thus, the use of FIG. 23 (b) instead of FIG. 23 (a) square

[0195] 也就是说,如果对于已经包含了长BSR的MAC PDU还剩余2个字节,则这意味着对于BSR有6个字节可用。 [0195] That is, if for long BSR already contains the MAC PDU further remaining 2 bytes, this means that for the BSR six bytes available. 那么,4个字节将用于长BSR,而其它2个字节将用于针对最后一个MAC SDU或者填充LCID的L字段。 Then, 4 bytes long for the BSR, and the other 2 bytes for the L field for the last MAC SDU or a filling of LCID. 因此,将使用图24 (b)或图24 (c)的格式而不是图24 (a)的格式。 Thus, using the format of FIG. 24 (b) or FIG. 24 (c) rather than the format of FIG. 24 (a) of.

[0196] 细节6 [0196] Details 6

[0197] 还将如下表述本发明的特征: [0197] The expression also features of the invention as follows:

[0198] 对于填充式BSR: [0198] For filling the formula BSR:

[0199] -如果填充比特数等于或大于短BSR的大小、但小于长BSR的大小,则报告包含最高优先级的逻辑信道(具有缓冲数据)的LCG的短BSR ; [0199] - If the number of padding bits is equal to or greater than the size of the short BSR, long BSR but smaller than the size of the report contains the highest priority logical channel the LCG short BSR (buffered data);

[0200]-否则,如果填充比特数等于或者大于长BSR的大小,则报告长BSR。 [0200] - Otherwise, if the number of padding bits is equal to or larger than the size of the long BSR, long BSR is reported.

[0201] 填充式BSR的定位 [0201] positioned BSR filled

[0202] 图22(b)中的BSR是填充式BSR,因为该BSR是由于填充空间而被包含。 [0202] BSR (b) in FIG. 22 is filled BSR, the BSR is because due to the filling space is included. 但是,由于该BSR不位于MAC PDU的结束处,所以,可能会有争议,这与填充式BSR的当前定义不一致。 However, since the BSR is not located at the end of the MAC PDU, it may be controversial, it is inconsistent with the current definition filled BSR. 然而,填充式BSR不必是MAC PDU中的最后一个元素。 However, not necessarily filled BSR is the last element in the MAC PDU. 此外,利用明确的LCID来指示填充式BSR。 In addition, the use of explicit LCID to indicate filled BSR. 因此,填充式BSR可以位于MAC PDU内部的任何位置处。 Thus, fill-in BSR can be located at any position within the MAC PDU.

[0203] 图25示出TB的2个字节剩余空间(填充式BSR是最后一个)的使用情况。 [0203] FIG. 25 shows two bytes of the remaining spaces (the last one is filled BSR) usage of TB.

[0204] 如果仍然强制要求填充式BSR应当是MAC PDU中除了填充之外的最后一个元素, 则这意味着应当使用图25 (b)。 [0204] If the still be mandatory filled BSR MAC PDU is the last element in addition to filling, this means that it should be used in FIG. 25 (b).

[0205] 在图25 (b)中,第二个MAC子报头没有"L"字段。 [0205] In FIG. 25 (b), the second MAC sub-header is not "L" field. 但是,由于其不是MAC PDU中的最后一个MAC子报头,图25 (b)可能不正确。 However, since it is not the last MAC PDU in a MAC sub-header, FIG. 25 (b) may be incorrect.

[0206] 很明显,具有BSR比不具有BSR更好。 [0206] It is clear, has a BSR BSR better than not have. 因此,应当使用图22 (b)而不是使用图25 (a)或图25 (b)。 Thus, it should be used in FIG. 22 (b) instead of FIG. 25 (a) or FIG. 25 (b). 因此,不应该限制BSR在MAC PDU内部的位置。 Thus, the location should not be limited within the MAC PDU BSR.

[0207] MAC控制元素(除了填充式BSR之外)始终位于任何MAC SDU之前。 [0207] MAC control elements (except filled BSR) is always located before any MAC SDU. 在MAC PDU的结束处进行填充式BSR。 BSR be filled at the end of the MAC PDU.

[0208] 除了MAC PDU中的最后一个子报头和大小固定的MAC控制元素之外,MAC PDU子报头包括六个报头字段R/R/E/LCID/F/L。 [0208] except the last subheader in the MAC PDU size and a fixed MAC control element, MAC PDU subheader includes six header fields R / R / E / LCID / F / L. MAC PDU中的最后一个子报头和大小固定的MAC 控制元素的子报头仅包括四个报头字段R/R/E/LCID。 And last subheader in the MAC PDU size fixed MAC Control element includes only four sub-header header fields R / R / E / LCID. 随后,与填充相对应的MAC PDU子报头包括四个报头字段R/R/E/LCID。 Subsequently, the filling of the corresponding MAC PDU sub-header comprises four header fields R / R / E / LCID.

[0209] 很明显,具有BSR比不具有BSR更好。 [0209] It is clear, has a BSR BSR better than not have. 就这方面而言,应当使用图22 (b)而不是图25 (a)或者图25 (b)。 In this regard, it should be used in FIG. 22 (b) instead of FIG. 25 (a) or FIG. 25 (b). 一种避免图25 (b)的方法是允许将填充式BSR设置在MAC H)U 内部的任何位置处。 One way to avoid FIG. 25 (b) of the method is to allow filled BSR disposed at any position MAC H) inside the U. 如果允许这样,则填充式BSR的触发条件将可以确保,只要有2个字节的填充空间可用就发送图22 (b)。 If this is allowed, the BSR trigger condition will be filled to ensure that, as long as the two bytes of space available to fill the transmission of FIG. 22 (b).

[0210] MAC PDU是在长度上按照字节对准(即,8个比特的倍数)的比特串。 [0210] MAC PDU is aligned on byte in length (i.e., a multiple of 8 bits) of the bit string. 可以用表(或列)来表示该比特串,其中,最高有效比特是该表的第一行的最左边的比特,最低有效比特是该表的最后一行的最右边的比特,更一般地,从左到右然后按照行的读取次序来读取该比特串。 Table can be (or column) to represent the bit string, wherein the most significant bit of the first row of the table is the leftmost bit, the least significant bit is the rightmost bit of the last row of the table, more generally, reading from left to right and then follow the order of the rows to read the bit string. 按照第一且最高有效比特位于最左比特、并且最后且最低有效比特位于最右比特, 来表示MAC PDU内部的各个参数字段的比特次序。 According to the first and the most significant bit is located in the left most bit, and the least significant bits and the last located rightmost bits to represent each bit order parameter field inside the MAC PDU.

[0211] MAC SDU是在长度上按照字节对准(即,8个比特的倍数)的比特串。 [0211] MAC SDU is byte-aligned in accordance with the length (i.e., a multiple of 8 bits) of the bit string. 从第一个比特开始向前将SDU包含到MAC PDU中。 Beginning from the first bit to forward the SDU included in the MAC PDU.

[0212] MAC PDU子报头具有与对应的MAC SDU、MAC控制元素和填充相同的次序。 [0212] MAC PDU sub-header having a sequence of elements corresponding to the same filling MAC SDU, MAC control.

[0213] 除了填充式BSR之外,MAC控制元素始终设置在任何MAC SDU之前。 [0213] In addition to the filled BSR, MAC control element is always provided before any MAC SDU. 填充式BSR可以设置在任何MAC SDU之前或者任何MAC SDU之后。 Filled BSR may be provided before any MAC SDU or MAC SDU after any.

[0214] 在上行方向中,除了当要求单个字节、但是不能通过在MAC PDU的结束处进行填充来实现时之外,在MAC PDU的结束处进行填充。 Addition to [0214], except when a single byte requirements, but can not be filled at the end of the MAC PDU in the upstream direction is achieved when filling at the end of the MAC PDU.

[0215] 在下行方向中,除了当需要单个字节或者两个字节的填充、但是不能通过在MAC PDU的结束处进行填充来实现时之外,在MAC PDU的结束处进行填充。 Addition to [0215], except when filling a single byte or two bytes required, but can not be filled at the end of the MAC PDU on the downlink is achieved when, at the end of filling the MAC PDU.

[0220] MAC PDU报头包括一个或者更多个MAC PDU子报头;各个子报头分别对应于MAC SDU、MAC控制元素或者填充。 [0220] MAC PDU header includes one or more MAC PDU sub-headers; each sub-header corresponding to a MAC SDU, MAC control element or padding. 用于填充的MAC PDU子报头在MAC PDU中出现不应当多于一次。 MAC PDU sub-header for filling occurs in the MAC PDU should not be more than once.

[0221] MAC PDU子报头具有与对应的MAC SDU、MAC控制元素和填充相同的次序。 [0221] MAC PDU sub-header having a sequence of elements corresponding to the same filling MAC SDU, MAC control.

[0222] 除了填充式BSR之外,MAC控制元素始终设置在任何MAC SDU之前。 [0222] In addition to the filled BSR, MAC control element is always provided before any MAC SDU. 在MAC PDU的结束处进行填充式BSR。 BSR be filled at the end of the MAC PDU.

[0227] 细节8 [0227] Details 8

[0228] 除了MAC PDU中的最后一个子报头和大小固定的MAC控制元素之外,MAC PDU子报头包括六个报头字段R/R/E/LCID/F/L。 [0228] except the last subheader in the MAC PDU size and a fixed MAC control element, MAC PDU subheader includes six header fields R / R / E / LCID / F / L. MAC PDU中的最后一个子报头和大小固定的MAC 控制元素的子报头仅包括四个报头字段R/R/E/LCID。 And last subheader in the MAC PDU size fixed MAC Control element includes only four sub-header header fields R / R / E / LCID. 随后,与填充相对应的MAC PDU子报头包括四个报头字段R/R/E/LCID。 Subsequently, the filling of the corresponding MAC PDU sub-header comprises four header fields R / R / E / LCID.

[0229] 填充比特数等于TB的大小减去MAC SDU或者MAC CE的大小、再减去它们相关的MAC子报头的大小。 [0229] the number of padding bits is equal to the TB size minus the size of the MAC SDU or MAC CE, and then subtracting the size of their associated MAC sub-header. 在此计算中,假设最后一个MAC SDU的MAC子报头具有"R/R/E/LCID/ F/L',。 In this calculation, it is assumed the last MAC SDU of MAC sub-header having a "R / R / E / LCID / F / L ',.

[0230] 除了填充式BSR之外,MAC控制元素始终设置在任何MAC SDU之前。 [0230] In addition to the filled BSR, MAC control element is always provided before any MAC SDU. 填充式BSR可以位于MAC PDU内部的任何位置处。 Filled BSR can be located at any position within the MAC PDU.

[0242] 对于填充式BSR : [0242] For filling the formula BSR:

[0243] -如果填充比特数等于或大于长BSR的大小,并且如果针对MAC PDU内部的MAC SDU的全部MAC子报头可以包括F和L字段,则报告长BSR。 [0243] - If the number of padding bits is equal to or greater than the size of the long BSR, and for the MAC SDU if the MAC PDU all internal MAC sub-header may include a field F and L, the report long BSR.

[0244] -否则,如果填充比特数等于或大于短BSR的大小,并且如果针对MAC PDU内部的MAC SDU的全部MAC子报头可以包括F和L字段,则报告包含最高优先级的逻辑信道(具有缓冲数据)的LCG的短BSR。 [0244] - Otherwise, if padding bits is equal to or greater than the size of the short BSR, and if for a MAC SDU inside the MAC PDU all the MAC subheader may include F and L field, the report contains the highest priority logical channel (with buffered data) of the LCG short BSR.

[0245] 以下,将说明可能的意义不明确的问题及其解决方案。 [0245] The following will illustrate possible equivocal problems and their solutions.

[0246] 图26 (a)示出剩余空间足够包含长BSR。 [0246] FIG. 26 (a) shows a remaining space long enough to contain the BSR. 但是,MAC PDU已经包含短BSR。 However, MAC PDU already comprises a short BSR. 根据当前的规范,当触发多个BSR时,仅将一个BSR包含到MAC PDU中。 According to the current specification, when a plurality of BSR is triggered, only one BSR included in the MAC PDU. 因此,在图26中,允许"短"且"常规的"BSR、或者"长"且"填充的" BSR这两种BSR中的一种。 Thus, in FIG. 26, allowing the "short" and "regular" BSR, or "long" and "filling" a, two BSR in the BSR. 图26 (b)和图26 (c)中示出类似的问题。 FIG. 26 (b) and 26 (c) shows a similar problem.

[0247] 因此,不清楚应当包含哪个BSR。 [0247] Thus, it is unclear which BSR should be included. 也就是说,"常规的"或"周期性的"BSR是否比"填充式"BSR具有更高的优先级。 That is, "conventional" or "periodic" whether the BSR than the "fill-in" the BSR has higher priority. 可能应该尽量选择长BSR。 You should probably try to choose long BSR. 或者,可能应该用长的填充式BSR来代替短的常规的BSR。 Alternatively, it may be filled with a long BSR instead of conventional short BSR. 另一方面,为了减轻实现复杂度,还可以提出允许在一个MAC PDU中出现多个BSR。 On the other hand, in order to reduce the implementation complexity, but also can make allowed in a plurality of BSR MAC PDU. 这是消除这种不明确性的另一种方法。 This is another way to eliminate this kind of ambiguity.

[0248] 因此,作为对上述多个BSR情形的一种可能的解决方案,可以在一个MAC PDU中包含多个BSR,图27的格式将替代图26的格式。 [0248] Accordingly, as a plurality of the above-described situation BSR possible solutions, the BSR may comprise a plurality of MAC PDU in the format of FIG. 27 will replace the format of FIG. 26.

[0249] 作为另一种可能解决方案,UE可包括一个长BSR。 [0249] As another possible solution, UE may include a long BSR. 也就是说,当UE构成MACPDU时, UE将剩余空间和已经分配给"常规的"和"周期性的" BSR的空间进行合并,以包含长BSR。 That is, when the UE constituting a MAC PDU, the UE and the remaining space has been allocated to "normal" and "periodic" BSR space are combined, to include a long BSR. 图28示出当将此解决方案应用于图26所示的问题时的MAC PDU的情况。 FIG 28 shows a case when a MAC PDU when this solution 26 applied to the problem shown in FIG.

[0250] 细节10 [0250] Details 10

[0251] 重要的是,调度器能够将填充式BSR与常规的BSR区分开。 [0251] Importantly, the scheduler can be separately filled with conventional BSR BSR region. 如果取消了位置限制, 则应当使用针对填充式BSR的单独LCID。 If the restriction cancel position, it should be used for a single LCID filled BSR. 此处,应当用填充子报头来明确指示出填充式BSR〇 Here, it should be filled with sub-header clearly indicates filled BSR〇

[0252] -如果填充比特数等于或大于短BSR加上它的子报头的大小、但小于长BSR加上它的子报头的大小,则报告包含最高优先级的逻辑信道(具有缓冲数据)的LCG的短BSR ; [0252] - If the number of padding bits is equal to or greater than the size of the short BSR plus its sub-header, but smaller than the size of the long BSR plus its sub-header, the report contains the highest priority logical channel (buffered data) LCG short the BSR;

[0253] -否则,如果填充比特数等于或者大于长BSR加上它的子报头的大小,则报告长BSR〇 [0253] - Otherwise, if the number of padding bits is equal to or greater than the size of the long BSR plus its sub-header, the report long BSR〇

[0254] 具有处理填充的通用规则可能比引入例外情况更简单:与是否包含常规的BSR无关,UE始终应用相同的规则来包含填充式BSR。 [0254] having a general rule the filling process may be simpler than in the case of introducing an exception: regardless of whether the BSR contain conventional, the same rules apply to contain the UE always filled BSR.

[0255] 如果BSR已经包含在MAC PDU中,则不需要其它BSR。 [0255] If a BSR has been included in the MAC PDU, then no additional BSR. 其它BSR可能增大MAC处理。 Other BSR MAC processing may be increased. 在构造了PDU之后重复(populate)BSR字段,因此,这两个BSR可能是同样的拷贝。 Repeating (the populate) after construction of the BSR field PDUs, and therefore, two copies of the same may be BSR.

[0256] 如果使用短BSR,则这意味着其它三个没有报告的组没有缓冲数据。 [0256] If the short BSR, this means that there is no other three groups reported no buffered data. 因此,短BSR ("常规的"或者"周期性的")可能暗示了全部组的缓冲区状态。 Thus, the BSR short ( "conventional" or "periodic") may imply the buffer status of all groups. 另一方面,如果使用长BSR, 则还可以报告全部组的缓冲区状态。 On the other hand, if the length of the BSR, then the entire buffer status report can also be set.

[0257] 细节11 [0257] Details 11

[0258] 需要考虑当触发多个BSR时应当包含的BSR的类型。 [0258] need to be considered when the plurality of BSR is triggered type that should be included in the BSR.

[0259] 即使在能够发送BSR的时候出现多个事件,也仅有1个BSR能够包含在MAC H)U 中。 [0259] Even if a plurality of events occur when the BSR can be transmitted, but also only one BSR can be included in the MAC H) U in.

[0260] 例如,当由于周期性定时器到期而触发短BSR、并且剩余填充空间足够包含长BSR 时,应当确定将要包含的BSR的类型。 [0260] For example, when the periodic timer expires since the short BSR is triggered, and the remaining filling space long enough to contain the BSR, will be the type contained in the BSR determined. 当触发了常规的短BSR并且填充空间仅允许短BSR 时,可以合并两个短BSR来生成长BSR。 When the trigger of a conventional short BSR and fill the space only allows a short BSR, BSR can merge two short afterlife grow BSR. 针对上述情形可能存在多种解决方案: There may be multiple solutions for the above scenario:

[0261] 选项A :当已经触发常规的BSR或者周期性的BSR时,不触发填充式BSR。 [0261] Option A: When the conventional BSR has been triggered or periodic BSR, filled BSR is not triggered. 这样,可以避免触发不同大小的多个BSR。 This avoids triggering multiple BSR different sizes.

[0262] 选项B:在MAC PDU中,最多可以包含常规的BSR或周期性的BSR中的一个,并且最多可以包含一个填充式BSR。 [0262] Option B: in the MAC PDU can contain up to a regular or periodic BSR in the BSR, and can contain a padding BSR formula.

[0263] 选项C :如果触发了常规的BSR或周期性的BSR,并且如果还触发了填充式BSR,则包含适配到MAC PDU中的最大BSR。 [0263] Option C: If the regular BSR is triggered or periodic BSR, and if it is filled triggered BSR, the MAC PDU fits into comprising the largest BSR.

[0264] 由于其简单性,上述选项A是最实用的。 [0264] Because of its simplicity, the above A is the most practical option.

[0265] 应当注意,有几种不同类型的BSR。 [0265] It should be noted that there are several different types of BSR. 当触发多个BSR时,仅包含一个BSR。 When the trigger multiple BSR, contains only one BSR.

[0266] 然而,针对当触发多个BSR时应当包含哪一种BSR方面,仍然存在问题。 [0266] However, when the trigger for multiple BSR BSR aspects which should be included, there are still problems. 当已经触发常规的BSR或者周期性的BSR时,不再触发填充式BSR。 When regular BSR has been triggered or periodic BSR, no BSR is triggered filled. MAC实体不能确定当触发多个BSR时包含哪一个BSR。 When the MAC entity can not determine which of a plurality of triggering a BSR BSR comprises.
