图 2示出了根据本发明的一个具体实施方式的***流程图。 Figure 2 illustrates a system flow diagram in accordance with an embodiment of the present invention.
首先, 在步骤 S20 中, 基站 1生成与每个分量载波相对应的资 源分配指示信息, 该资源分配指示信息用于指示分配给用户终端 2 的资源的相关信息, 也即, 每个分量载波上均对应一个资源分配指 示信息, 也即 UL grant或 DL assignment, UL grant中包括为用户终 端 2向基站 1传输上行数据所分配的资源信息, 例如分配的起始资 源块的序号和终止的资源块的序号, 以及与该分配的资源块所对应 的调制和编码方式。 DL assignment中包括为基站 1向用户终端 2传 输下行数据所分配的资源信息, 例如分配的起始资源块的序号和终 止的资源块的序号, 以及与该分配的资源块所对应的调制和编码方 式。 First, in step S20, the base station 1 generates resource allocation indication information corresponding to each component carrier, where the resource allocation indication information is used to indicate related information of resources allocated to the user terminal 2, that is, on each component carrier. Each of the UL grants includes a resource allocation indication information, that is, a UL grant or a DL assignment, and the UL grant includes resource information allocated for transmitting the uplink data to the base station 1 by the user terminal 2, for example, the sequence number of the allocated initial resource block and the terminated resource block. The sequence number, and the modulation and coding method corresponding to the allocated resource block. The DL assignment includes resource information allocated for transmitting downlink data to the user terminal 2 by the base station 1, such as the sequence number of the allocated start resource block and the sequence number of the terminated resource block, and the modulation and coding corresponding to the allocated resource block. the way.
对于下行数据传输, 基站 1 为了有效地将数据封装在由资源分 配指示信息所指示的传输块(Transport Block, TB ) 中, 基站 1需要 对资源分配指示信息进行编号, 也即, 获取资源分配指示信息的次 序标识, 并按照预定规则将数据依次封装在由各个具有不同的次序 标识的资源分配指示信息所指示的传输块中。 同样地, 对于来自用 户终端 2的上行数据, 当基站 1接收到来自用户终端 2的多个传输
块时, 基站 1也需要知道各个传输块的次序标识, 并按照预定规则, 对来自用户终端 2的数据进行解封装。 For the downlink data transmission, in order to effectively encapsulate the data in the transport block (TB) indicated by the resource allocation indication information, the base station 1 needs to number the resource allocation indication information, that is, obtain the resource allocation indication. The order of the information is identified, and the data is sequentially encapsulated in a transport block indicated by each of the resource allocation indication information identified by the different order according to a predetermined rule. Similarly, for uplink data from the user terminal 2, when the base station 1 receives multiple transmissions from the user terminal 2 At the time of the block, the base station 1 also needs to know the order identification of each transport block, and decapsulate the data from the user terminal 2 according to a predetermined rule.
因此, 在步骤 S21 中, 基站 1根据每个资源分配指示信息, 确 定每个资源分配指示信息的次序标识。 以下, 分别通过两个具体的 实施方式, 对基站 1 为资源分配指示信息进行编号的方法进行具体 的描述。 Therefore, in step S21, the base station 1 determines the order identification of each resource allocation indication information based on each resource allocation indication information. In the following, the method for numbering the resource allocation indication information by the base station 1 is specifically described by using two specific implementation manners.
> 静态或半静态方式 > static or semi-static
基站 1 可以根据分量载波的次序标识, 确定与每个分量载波相 对应的每个资源分配指示信息的次序标识, 也即, 资源分配指示信 息的编号。 例如, CC1所对应的资源分配指示信息的编号为 1 , CC2 所对应的资源分配指示信息的编号为 2, CC3所对应的资源分配指示 信息的编号为 3 , CC4所对应的资源分配指示信息的编号为 4。 在另 一个实施方式中, 如果用户终端 2被配置了 3 个 CC, 例如分别为 CC1 , CC3和 CC5 , 则与 CC1所对应的资源分配指示信息的编号为 1 , 与 CC3所对应的资源分配指示信息的编号为 2, 与 CC5所对应的 资源分配指示信息的编号为 3。 当然, 上述的方式仅为示例, 本领域 技术人员可以理解, 也可以釆用 CC1所对应的资源分配指示信息的 编号为 4, CC2所对应的资源分配指示信息的编号为 3 , CC3所对应 的资源分配指示信息的编号为 2, CC4所对应的资源分配指示信息的 编号为 1 的方式确定资源分配指示信息的编号。 因为分量载波与资 源分配指示信息是——对应的, 因此, 采用这种方式可以方便地确 定资源分配指示信息的次序标识。 The base station 1 may determine the order identifier of each resource allocation indication information corresponding to each component carrier according to the order identification of the component carriers, that is, the number of the resource allocation indication information. For example, the number of resource allocation indication information corresponding to CC1 is 1, the number of resource allocation indication information corresponding to CC2 is 2, and the number of resource allocation indication information corresponding to CC3 is 3, and resource allocation indication information corresponding to CC4 The number is 4. In another embodiment, if the user terminal 2 is configured with 3 CCs, for example, CC1, CC3, and CC5, respectively, the resource allocation indication information corresponding to the CC1 is 1 and the resource allocation indication corresponding to the CC3. The number of the information is 2, and the number of resource allocation indication information corresponding to CC5 is 3. Certainly, the foregoing manner is only an example, and those skilled in the art may understand that the number of resource allocation indication information corresponding to CC1 may be 4, and the number of resource allocation indication information corresponding to CC2 is 3, corresponding to CC3. The number of the resource allocation indication information is 2, and the number of the resource allocation indication information corresponding to the CC4 is 1 to determine the number of the resource allocation indication information. Since the component carrier and the resource allocation indication information are - corresponding, the order identification of the resource allocation indication information can be conveniently determined in this manner.
> 动态方式 > Dynamic mode
除了上述的根据分量载波的次序标识信息确定资源分配指示信 息的次序标识的方式外, 还可以根据资源分配指示信息所指示的资 源的本身的性质, 确定资源分配指示信息的次序标识。 In addition to the manner of determining the order identifier of the resource allocation indication information according to the order identification information of the component carrier, the order identifier of the resource allocation indication information may be determined according to the nature of the resource indicated by the resource allocation indication information.
因为在资源分配指示信息中包含分配给用户终端的资源块的大 小信息和调制和编码方式, 因此, 基站 1 还可以根据资源块的大小 和 /或调制和编码方式对资源分配指示信息进行排序。 例如, 如果基
站 1按照资源块的大小进行排序时, 可以将指示为用户终端 2分配 最大的资源块的资源分配指示信息编号为 1 ,将指示为用户终端 2分 配次大的资源块的资源分配指示信息编号为 2, 以此类推。 如果基站 1 按照资源块所采用的调制和编码方式为资源分配指示信息进行排 序时, 例如, 基站 1 可以将指示对资源块采用高阶调制编码方式的 资源分配指示信息编号为 1 , 阶数越低, 编号越大。 例如, 对于分别 指示采用 64QAM, 16QAM和 QPSK的资源分配指示信息, 基站 1 将指示调制和编码方式为 64QAM的资源分配指示信息编号为 1 , 将 指示调制和编码方式为 16QAM的资源分配指示信息编号为 2, 将指 示调制和编码方式为 QPSK的资源分配指示信息编号为 3。 其中, 一 个 64QAM星座点能同时承载 6bit信息, 一个 16QAM星座点能同时 承载 4bit信息, 而一个 QPSK星座点能同时承载 2bit信息。 Since the resource allocation indication information includes the size information of the resource block allocated to the user terminal and the modulation and coding mode, the base station 1 may also sort the resource allocation indication information according to the size of the resource block and/or the modulation and coding manner. For example, if the base When the station 1 sorts the size of the resource block, the resource allocation indication information indicating that the user terminal 2 is allocated the largest resource block may be numbered 1, and the resource allocation indication information number indicating that the user terminal 2 is allocated the next largest resource block. 2, and so on. If the base station 1 sorts the resource allocation indication information according to the modulation and coding mode adopted by the resource block, for example, the base station 1 may number the resource allocation indication information indicating that the resource block adopts the high-order modulation and coding mode to 1, and the order is higher. Low, the number is larger. For example, for the resource allocation indication information indicating that 64QAM, 16QAM, and QPSK are respectively used, the base station 1 numbers the resource allocation indication information indicating that the modulation and coding mode is 64QAM to 1, and the resource allocation indication information number indicating that the modulation and coding mode is 16QAM. 2, the resource allocation indication information indicating that the modulation and coding mode is QPSK is numbered 3. Among them, a 64QAM constellation point can carry 6bit information at the same time, a 16QAM constellation point can carry 4bit information at the same time, and a QPSK constellation point can carry 2bit information at the same time.
当然, 基站 1 可以结合资源分配指示信息中的分配的资源块大 小和调制和编码方式对资源分配指示信息进行排序。 例如, 先按照 资源块大小对资源分配指示信息进行排序, 如果各个资源分配指示 信息所指示的资源块大小均相同, 则按照调制和编码方式的阶数顺 序对资源分配指示信息进行排序。 当然, 也可以先按照调制和编码 方式的阶数顺序, 再按照资源块大小对资源分配指示信息进行排序。 这种动态的方式, 不需要额外的信令开销, 节省了带宽资源。 但是, 可能存在这种情况, 即各个资源分配指示信息所指示的资源块大小 相同, 且所采用的调制和编码方式也相同, 因此, 此时需要采用静 态或半静态方式, 也即基站 1 根据分量载波的次序标识, 确定与每 个分量载波相对应的每个资源分配指示信息的次序标识。 Of course, the base station 1 can sort the resource allocation indication information in combination with the allocated resource block size and the modulation and coding manner in the resource allocation indication information. For example, the resource allocation indication information is first sorted according to the resource block size. If the resource block sizes indicated by the respective resource allocation indication information are the same, the resource allocation indication information is sorted according to the order of the modulation and coding modes. Of course, the resource allocation indication information may also be sorted according to the resource block size according to the order of the modulation and coding modes. This dynamic approach eliminates the need for additional signaling overhead and saves bandwidth resources. However, there may be a case where the resource block size indicated by each resource allocation indication information is the same, and the modulation and coding methods used are also the same. Therefore, the static or semi-static mode is required, that is, the base station 1 is based on The order identification of the component carriers determines the order identification of each resource allocation indication information corresponding to each component carrier.
当然, 基站 1 需要将如何确定资源分配信息的次序标识的规则 通知用户终端 2,从而用户终端 2可以知道是根据资源块的大小信息 还是根据调制和编码方式或两者的结合确定资源分配信息的次序标 识。 Of course, the base station 1 needs to notify the user terminal 2 of the rule of how to determine the order identification of the resource allocation information, so that the user terminal 2 can know whether the resource allocation information is determined according to the size information of the resource block or according to the modulation and coding mode or a combination of the two. Order identification.
因为基站 1 生成这些资源分配信息, 因此, 基站 1知道这些资 源分配指示信息的次序标识。
然后, 在步骤 S22 中, 基站 1根据每个资源分配指示信息的次 序标识、 按照预定规则将用户数据封装在与每个资源分配指示信息 相对应的每个传输块中并发送给用户终端 2。首先以下行数据为例进 行说明。 对于下行数据, 例如, 当基站 1 有多个业务需要发送给用 户终端 2, 其中的每个业务包括最低发送数据量, 该最低发送数据量 表示传送该业务的数据量的下限, 因此, 该预定规则包括: 基站 1 先将各个业务的最低发送数据量均封装在编号为 1的 DL assignment 所指示的传输块中, 如果该传输块还有剩余的资源, 则将优先级最 高的业务的剩余的数据再封装到该传输块中, 然后, 如果编号为 1 的 DL assignment所指示的传输块已经被占满, 则将优先级最高的业 务的剩余的数据再封装到编号为 2的 DL assignment所指示的传输块 中, 依次类推, 从而优化了逻辑信道优先级的流程。 当然, 可选地, 该预定规则也可以是: 基站 1 先将各个业务的最低发送数据量均封 装在编号为 4的 DL assignment所指示的传输块中, 如果该传输块还 有剩余的资源, 则将优先级最高的业务的剩余的数据再封装到该传 输块中, 然后, 如果编号为 4的 DL assignment所指示的传输块已经 被占满, 则将优先级最高的业务的剩余的数据再封装到编号为 3 的 DL assignment所指示的传输块中, 依次类推, 从而优化了逻辑信道 优先级的流程。 Since the base station 1 generates these resource allocation information, the base station 1 knows the order identification of these resource allocation indication information. Then, in step S22, the base station 1 identifies the user data in accordance with the order of each resource allocation indication information, encapsulates the user data in each transport block corresponding to each resource allocation indication information, and transmits it to the user terminal 2. First, the following line data is taken as an example for explanation. For downlink data, for example, when the base station 1 has multiple services that need to be sent to the user terminal 2, each of the services includes a minimum transmitted data amount, and the minimum transmitted data amount represents a lower limit of the amount of data for transmitting the service, and therefore, the predetermined The rules include: The base station 1 first encapsulates the minimum transmission data amount of each service in the transport block indicated by the DL assignment numbered 1, and if the transport block has remaining resources, the remaining service of the highest priority service Data is repackaged into the transport block, and then, if the transport block indicated by the DL assignment numbered 1 is already full, the remaining data of the highest priority service is repackaged to the DL assignment numbered 2 In the transport block, and so on, the flow of the logical channel priority is optimized. Of course, the predetermined rule may also be: The base station 1 first encapsulates the lowest transmission data amount of each service in the transport block indicated by the DL assignment numbered 4, if the transport block has remaining resources, Transmitting the remaining data of the highest priority service into the transport block, and then, if the transport block indicated by the DL assignment number 4 is already full, the remaining data of the service with the highest priority is re Encapsulation into the transport block indicated by the DL assignment numbered 3, and so on, optimizes the flow of the logical channel priority.
然后, 在步骤 S23 中, 基站 1将资源分配指示信息通知用户终 端 2。 基站 1 通过物理下行控制信道 (Physical Downlink Control Channel, PDCCH )将 UL grant或 DL assignment消息通知给用户终端 2。 本领域技术人员可以理解, 步骤 S22与步骤 S23之间没有明显的 先后次序。 Then, in step S23, the base station 1 notifies the user terminal 2 of the resource allocation indication information. The base station 1 notifies the user terminal 2 of the UL grant or DL assignment message through a Physical Downlink Control Channel (PDCCH). Those skilled in the art can understand that there is no obvious order between step S22 and step S23.
在另一个实施方式中, 基站 1 还需要将每个分量载波的次序标 识, 也即 CC Index通知用户终端 2, 例如, CC1 , CC2 , CC3和 CC4。 基站 1可以利用广播信道,例如物理下行共享信道( Physical Downlink Shared CHannel , PDSCH ) 或者物理广播信道 (Physical Broadcast Channel, PBCH )发送该 CC index信息, 或者利用专用信道, 例如
采用高层控制信息,例如无线资源控制消息( Radio Resource Control, RRC ) 或者媒体接入控制层控制消息进行传输。 In another embodiment, the base station 1 also needs to identify the order of each component carrier, that is, the CC Index, to notify the user terminal 2, for example, CC1, CC2, CC3, and CC4. The base station 1 may transmit the CC index information by using a broadcast channel, such as a Physical Downlink Shared CHannel (PDSCH) or a Physical Broadcast Channel (PBCH), or use a dedicated channel, for example The high-level control information, such as a Radio Resource Control (RRC) or a medium access control layer control message, is used for transmission.
在另一个实施方式中, 基站 1 将每个分量载波的次序标识和分 量载波与频点之间的对应关系通知给用户终端 2。基站 1可以利用广 播信道, 例如物理下行共享信道或者物理广播信道发送该 CC index 信息和对应关系, 或者基站 1 利用专用信道, 例如采用高层控制信 息, 例如无线资源控制消息或者媒体接入控制层控制消息进行传输 CC index信息和对应关系。 In another embodiment, the base station 1 notifies the user terminal 2 of the order identification of each component carrier and the correspondence between the component carrier and the frequency point. The base station 1 may transmit the CC index information and the corresponding relationship by using a broadcast channel, such as a physical downlink shared channel or a physical broadcast channel, or the base station 1 may use a dedicated channel, for example, using high layer control information, such as a radio resource control message or a medium access control layer. The message transmits CC index information and correspondence.
在步驟 S24中, 用户终端 2接收来自基站 1 的与每个分量载波 相对应的资源分配指示信息, 该资源分配指示信息用于指示分配给 所述用户终端的资源的相关信息。 In step S24, the user terminal 2 receives resource allocation indication information corresponding to each component carrier from the base station 1, and the resource allocation indication information is used to indicate related information of resources allocated to the user terminal.
然后, 在步骤 S25中, 用户终端 2根据每个资源分配指示信息, 确定每个资源分配指示信息的次序标识。 Then, in step S25, the user terminal 2 determines the order identification of each resource allocation indication information based on each resource allocation indication information.
例如, 基站 1在 PDCCH信道的 DL CC上发送 UL grant消息, 则用户终端根据该 DL CC 以及***信息块 2 ( System Information Block, SIB2 ), 该 SIB2中包含了上行链路与下行链路之间的对应关 系, 用户终端 2能够获取该 UL grant所作用的分量载波; 此外, 当 PDCCH中包含载波指示域 ( Carrier Indication Field, CIF ) 时, 用户 终端 2根据 CIF中的信息, 也可以获取 PDCCH中的 UL grant或者 DL assignment所作用的分量载波。 For example, the base station 1 transmits a UL grant message on the DL CC of the PDCCH channel, and the user terminal according to the DL CC and the System Information Block 2 (SIB2), the SIB2 includes the uplink and the downlink. For the corresponding relationship, the user terminal 2 can obtain the component carrier to which the UL grant is applied. In addition, when the PDCCH includes a carrier indication field (CIF), the user terminal 2 can also acquire the PDCCH according to the information in the CIF. The component carrier to which the UL grant or DL assignment acts.
此外, 用户终端 2 预先知道是采用静态的方式还是动态的方式 获取资源分配指示信息的次序标识, 例如, 基站 1 通过高层的配置 信息通知用户终端 2 釆用何种方式, 当然, 采用静态或者动态的方 式也可以是***预先已经配置好, 因此, 不需要基站 1 通过信令通 知用户终端 2。 In addition, the user terminal 2 knows in advance whether to obtain the order identifier of the resource allocation indication information in a static manner or in a dynamic manner. For example, the base station 1 notifies the user terminal 2 by using the configuration information of the upper layer, and of course, adopts static or dynamic The method may also be that the system has been configured in advance, and therefore, the base station 1 is not required to notify the user terminal 2 by signaling.
当用户终端 2知道采用静态的方式与基站 1 同步资源分配指示 信息的次序标识时, 用户终端根据在 PDCCH 信道上接收到的 UL grant或 DL assignment中的分配的资源所对应的分量载波的频率信 息, 并且根据来自基站 1的广播信道或者专用信道获得 CC index信
息以及 CC index 与频率之间的映射关系, 获取与 UL grant或 DL assignment中所分配的频率资源相对应的 CC index,又因为 CC index 与 UL grant或 DL assignment之间具有一定的对应关系, 因此, 根据 CC index, 用户终端 1可以确定 UL grant或者 DL assignment的次序 标识。 当然 CC index与 UL grant或者 DL assignment次序之间的对 应关系可以根据不同的无线通信***进行配置, 并且基站 1 需要将 该配置信息提前通知用户终端 2。 When the user terminal 2 knows that the sequence identification of the resource allocation indication information is synchronized with the base station 1 in a static manner, the frequency information of the component carrier corresponding to the allocated resource in the UL grant or the DL assignment received by the user terminal on the PDCCH channel is used. And obtaining a CC index letter based on a broadcast channel or a dedicated channel from the base station 1. And the mapping between the CC index and the frequency, obtaining the CC index corresponding to the frequency resource allocated in the UL grant or the DL assignment, and because the CC index has a certain correspondence with the UL grant or the DL assignment, According to the CC index, the user terminal 1 can determine the order identifier of the UL grant or the DL assignment. Of course, the correspondence between the CC index and the UL grant or the DL assignment order can be configured according to different wireless communication systems, and the base station 1 needs to notify the user terminal 2 of the configuration information in advance.
当基站 1 与用户终端 2之间采用动态的方式确定资源分配指示 信息的次序标识时, 也即, 此时, 用户终端 2 已经知道是釆用根据 资源块的大小信息还是根据调制和编码方式或两者的结合确定资源 分配信息的次序标识, 因此, 相应地, 用户终端 2采用相应的方式, 确定资源分配指示信息的次序标识。 该确定的过程与基站 1 端釆用 的确定方式是一致的, 因此, 在此不予赘述。 When the base station 1 and the user terminal 2 determine the order identifier of the resource allocation indication information in a dynamic manner, that is, at this time, the user terminal 2 already knows whether to use the size information according to the resource block or according to the modulation and coding mode or The combination of the two determines the order identification of the resource allocation information, and accordingly, the user terminal 2 determines the order identification of the resource allocation indication information in a corresponding manner. The process of determining is consistent with the determination of the use of the base station 1 and, therefore, will not be described herein.
然后, 先以下行数据为例, 对用户终端 2使用该资源分配指示 信息的次序信息进行具体的描述。 Then, the following line data is taken as an example to specifically describe the order information of the resource allocation indication information by the user terminal 2.
在步骤 S26中, 用户终端 2根据每个资源分配指示信息的次序 标识按照预定规则对接收的来自基站 1 的每个传输块中的数据进行 解封装。 例如, 用户终端 2知道基站 1按照先将业务数据封装在编 号最小的 DL assignment所指示的传输块中, 例如 DL assignment 1 所指示的 TB 1, 然后再将剩余的业务数据封装在编号次小的 DL assignment所指示的传输块中,例如, DL assignment 2所指示的 TB 2 中的顺序对业务数据进行封装, 因此, 用户终端 2 按照该顺序, 对 各个传输块中的数据进行解封装, 例如, 先解封装 DL assignment 1 所指示的 TB 1 , 再解封装 DL assignment 2所指示的 TB 2。 当然, 以 上的解封装的顺序仅为示例, 本领域技术人员可以理解, 对于多个 TB , 也可以并行地解封装, 或者按照其他次序顺序地解封装。 如果 一个高层数据包, 例如 RRC PDU被分别封装在至少两个 TB中, 例 如, 一个 RRC PDU被分段在 TBI和 TB2中, 则因为用户终端 2根 据 DL assignment中的信息,用户终端 2中的接收机知道 TBI和 TB2
的顺序, 因此, 用户终端 2可以将 TBI 的最后一个分段 (如果存在) 和 TB2的第一个分段(如果存在) 进行联合处理, 以获得原始的数 据包。 上述方式对于一个 R C PDU被分别封装在两个以上的 TB的 情形同样适用。 In step S26, the user terminal 2 identifies that the received data in each transport block from the base station 1 is decapsulated according to a predetermined rule according to the order of each resource allocation indication information. For example, the user terminal 2 knows that the base station 1 first encapsulates the service data in the transport block indicated by the DL assignment with the lowest number, for example, TB1 indicated by DL assignment 1, and then encapsulates the remaining service data in the second smallest number. In the transport block indicated by the DL assignment, for example, the order in the TB 2 indicated by the DL assignment 2 encapsulates the service data, and therefore, the user terminal 2 decapsulates the data in each transport block in this order, for example, First, TB 1 indicated by DL assignment 1 is decapsulated, and TB 2 indicated by DL assignment 2 is decapsulated. Of course, the order of the above decapsulation is only an example, and those skilled in the art can understand that for multiple TBs, they can also be decapsulated in parallel, or sequentially decapsulated in other orders. If a higher layer data packet, for example, an RRC PDU, is separately encapsulated in at least two TBs, for example, one RRC PDU is segmented in TBI and TB2, because the user terminal 2 is in the user terminal 2 according to the information in the DL assignment The receiver knows TBI and TB2 The order, therefore, user terminal 2 can jointly process the last segment of the TBI (if present) and the first segment of TB2 (if present) to obtain the original packet. The above method is also applicable to the case where one RC PDU is separately packaged in two or more TBs.
以上以下行数据为例对基站 1 和用户终端 2之间对资源分配指 示信息的次序信息的同步进行说明, 以下, 以上行数据传输为例对 基站 1 和用户终端 2之间对资源分配指示信息的次序信息的同步进 行简要的说明。 在另一个实施方式中, 对于上行数据, 在步驟 S25 中用户终端 2根据每个资源分配指示信息, 确定每个资源分配指示 信息的次序标识之后, 在步驟 S27中, 用户终端 2根据每个资源分 配指示信息的次序标识按照预定规则将用户数据封装在与每个资源 分配指示信息相对应的每个传输块中, 该封装的过程与基站 1 端的 步驟 S22类似, 在此不予赘述, 然后, 用户终端 2将该封装后的传 输块发送给基站 1。 The following line data is used as an example to describe the synchronization of the order information of the resource allocation indication information between the base station 1 and the user terminal 2. Hereinafter, the above data transmission is used as an example to allocate resource indication information between the base station 1 and the user terminal 2. The synchronization of the order information is briefly explained. In another embodiment, for the uplink data, after the user terminal 2 determines the order identifier of each resource allocation indication information according to each resource allocation indication information in step S25, the user terminal 2 according to each resource in step S27. The order of the allocation indication information is to encapsulate the user data in each of the transport blocks corresponding to each of the resource allocation indication information according to a predetermined rule. The process of the encapsulation is similar to the step S22 of the base station 1 and is not described herein. The user terminal 2 transmits the encapsulated transport block to the base station 1.
然后, 在步骤 S28 中, 基站 1根据每个资源分配指示信息的次 序标识、 按照预定规则对接收的来自用户终端 2 的每个传输块中的 数据进行解封装。 因为资源分配指示信息是基站 1 生成的, 所以基 站 1知道 UL grant的次序标识, 因此, 基站 1直接按照该次序标识, 对接收到的来自用户终端 2的上行数据进行解封装。 Then, in step S28, the base station 1 decapsulates the received data in each transport block from the user terminal 2 according to a predetermined rule according to the secondary identification of each resource allocation indication information. Since the resource allocation indication information is generated by the base station 1, the base station 1 knows the order identifier of the UL grant. Therefore, the base station 1 directly identifies the received uplink data from the user terminal 2 according to the order identification.
在上述实施方式中, 为了便于说明, 先对下行的数据传输进行 描述, 也即步骤 S26; 然后再对上行数据传输进行描述, 也即步骤 S27和步骤 S28。 本领域技术人员可以理解, 上行数据传输与下行数 据传输之间没有明显的先后顺序, 因此上述的步骤的序号并不表示 实际执行时的先后顺序。 In the above embodiment, for convenience of explanation, the downlink data transmission is first described, that is, step S26; and then the uplink data transmission is described, that is, step S27 and step S28. Those skilled in the art can understand that there is no obvious sequence between the uplink data transmission and the downlink data transmission, and therefore the sequence numbers of the above steps do not indicate the order of actual execution.
