LTE中继回程的上行链路控制方法和设备 Uplink control method and device for LTE relay backhaul

技术领域 Technical field

本发明的实施例设计长期演进（LTE)***，具体涉及一种在 LTE-Advanced 中继回程的上行链路控制方法和设备。背景技术 Embodiments of the present invention design a Long Term Evolution (LTE) system, and in particular, an uplink control method and apparatus for LTE-Advanced relay backhaul. Background technique

在 LTE-Advanced中继***中，中继节点（RN) 经由 Un接口（回程链路）连接至 eNB并经由 Uu接口（访问链路）连接至其 UE。 In an LTE-Advanced relay system, a relay node (RN) is connected to an eNB via an Un interface (backhaul link) and to its UE via a Uu interface (access link).

在 Uu接口上，由 UE来执行上行链路速率控制，以管理 RB之间对上行链路资源的共享。上行链路速率控制是通过执行逻辑信道（即，无线承载（RB)) 优先处理来实现的。例如，可以利用参数，包括优先级别、优先处理比特率（PBR) 和漏桶大小持续时间（BSD), 基于令牌漏桶算法来控制每一个 RB 的上行链路速率。 On the Uu interface, uplink rate control is performed by the UE to manage the sharing of uplink resources between the RBs. Uplink rate control is achieved by performing logical channel (i.e., radio bearer (RB)) prioritization. For example, parameters can be utilized, including priority level, priority processing bit rate (PBR), and leaky bucket size duration (BSD), based on the token leaky bucket algorithm to control the uplink rate of each RB.

同样，在 Un接口上， RN也需要上行链路速率控制并执行优先处理操作。 Un接口具有不同的业务行为，例如，在 Un接口上聚集了来自不同 UE的大量 RB, 这些 RB承载着不同的业务类型，语音、数据、视频等等。 Similarly, on the Un interface, the RN also needs uplink rate control and performs priority processing operations. The Un interface has different service behaviors. For example, a large number of RBs from different UEs are aggregated on the Un interface. These RBs carry different service types, voice, data, video, and so on.

图 1示出了 LTE-Advanced中继***中在中继回程上的现有上行链路速率控制的示意框图。 Figure 1 shows a schematic block diagram of an existing uplink rate control on a relay backhaul in an LTE-Advanced relay system.

如图 1所示，在现有的 LTE-Advanced中继***中，访问链路（Uu接口）上的 Uu RB (来自 UE3的 RB3-2、 RB3-1 , 来自 UE2的 RB2-3、 RB2-2、 RB2-1 , 以及来自 UE1的 RBl-2、 RB1-1 ) 经过 RN映像（复用）成回程链路（Un接口）上的 Un RB (例如，针对 UE3的 Un RB3、针对 UE2的 Un RB2、针对 UE1的 Un RBl ), RN仅针对这些 Un RB来分配上行链路资源， SP , 管理 Un RB之间对上行链路资源的共享，而并没有考虑各个 Uu RB之间的资源调度，即如何在 Uu RB之间分配 Un RB的资源， Uu RB的业务只是采用先到先服务的原则复用到 Un RB上。这种仅一级优先处理方式不能保证各 Uu RB在回程链路上得到高的服务质量（QoS )。发明内容 As shown in FIG. 1, in the existing LTE-Advanced relay system, Uu RBs on the access link (Uu interface) (RB3-2, RB3-1 from UE3, RB2-3, RB2- from UE2) 2. RB2-1, and RBl-2, RB1-1 from UE1 are RN mapped (multiplexed) into Un RB on the backhaul link (Un interface) (for example, Un RB3 for UE3, Un for UE2) RB2, for Un RB1 of UE1, the RN allocates uplink resources only for these Un RBs, SP, manages the sharing of uplink resources between Un RBs, and does not consider resource scheduling between each Uu RB. That is, how to allocate Un RB resources between Uu RBs, and Uu RB services are multiplexed onto Un RBs on a first-come, first-served basis. This first-level priority only approach does not guarantee that each Uu RB gets a high quality of service (QoS) on the backhaul link. Summary of the invention

The following description provides detailed details of a comprehensive understanding of these embodiments. However, it will be understood by those skilled in the art that the present invention may be practiced without some of the details. In addition, some well-known structures or functions may not be shown or described in detail to avoid unnecessarily obscuring the description of various embodiments of the invention. The basic idea of the embodiment of the present invention is to implement uplink rate control on the backhaul link by performing two-level priority processing on the uplink of the backhaul link, thereby overcoming the prior art to adopt only the first-level priority processing.

For example, RB3-1 indicates an RB of QoS class 1 belonging to UE3.

第一实施例 First embodiment

图 2 示出了根据本发明第一实施例的回程链路上的上行链路速率控制的示意性框图。在本实施例中， ***采用按照 QoS映像。在这种情况下，对回程链路无线承载（Un RB ) 执行第一级优先处理，所述 Un RB是由至少一个用户设备（UE) 的访问链路无线承载（Uu RB ) 按照服务质量 QoS映像成的 RB组；以及对每一个 Un RB所汇聚的 Uu RB执行第二级优先处理。 Fig. 2 shows a schematic block diagram of uplink rate control on a backhaul link in accordance with a first embodiment of the present invention. In this embodiment, the system is based on a QoS image. In this case, the first-level priority processing is performed on the backhaul link radio bearer (Un RB ), which is the access link radio bearer (Uu RB ) of at least one user equipment (UE) according to the quality of service QoS. The mapped RB group; and performing a second level of priority processing on the Uu RBs aggregated by each Un RB.

如图 2所示，在按照 QoS映像的情况下，至少一个 UE的 Uu RB按照服务质量 QoS映像成的 RB组， SP Un RB。例如， Uu RB按照 QoS等级来分类，相同或相似 QoS等级的 Uu RB分为一组。例如， QoS等级为 3的 Uu RB2-3> Uu RBI -3映像（复用）成 Un RB3 , QoS等级为 2的 Uu RB3-2 Uu RB2-2和 Uu RB1-2 映像（复用）成 Un RB2, QoS等级为 1的 Uu RB3-1、 Uu RB2-1和 Uu RB1-1 映像（复用）成 Un RBl。 As shown in FIG. 2, in the case of QoS mapping, the Uu RB of at least one UE is mapped into an RB group, SP Un RB according to the quality of service QoS. For example, Uu RBs are classified according to QoS class, and Uu RBs of the same or similar QoS class are grouped. For example, Uu RB2-3 with QoS level 3 > Uu RBI -3 image (multiplexed) into Un RB3, Uu RB3-2 Uu RB2-2 with QoS level 2 and Uu RB1-2 image (multiplexed) into Un RB2, Uu RB3-1, Uu RB2-1, and Uu RB1-1 image with QoS class 1 (multiplexed) into Un RB1.

The uplink rate control on the backhaul link is thus achieved by these two levels of priority processing.

第二实施例 Second embodiment

图 3 示出了根据本发明第二实施例的回程链路上的上行链路速率控制的示意性框图。在本实施例中， ***采用按照 UE映像，在这种情况下，对 Un RB 执行第一级优先处理，所述 Un RB是由至少一个 UE的 Uu RB按照 UE映像成的 RB组；以及对每一个 Un RB所汇聚的 Uu RB执行第二级优先处理。 FIG. 3 shows a schematic block diagram of uplink rate control on a backhaul link in accordance with a second embodiment of the present invention. In this embodiment, the system adopts a UE image, in this case, for Un RB The first level of priority processing is performed, where the Un RB is an RB group that is mapped by the Uu RB of the at least one UE according to the UE; and the second level of priority processing is performed on the Uu RB that is aggregated by each Un RB.

如图 3所示，在按照 UE映像的情况下，至少一个 UE的 UuRB按照 UE映像成的 RB组，即 UnRB, 例如，属于 UE3的 Uu RB3-2、 UuRB3-l映像（复用）成 UnRB3，属于 UE2的 UuRB2-3、 Uu RB2-2和 Uu RB2-1映像（复用）成 Un RB2, 属于 UE1的 UuRBl-3、 Uu RB1-2禾 Π Uu RB1-1映像（复用）成 UnRBl。 As shown in FIG. 3, in the case of the UE mapping, the UuRB of at least one UE is in accordance with the RB group formed by the UE, that is, the UnRB, for example, the Uu RB3-2 and the UuRB3-l belonging to the UE3 are mapped (multiplexed) into the UnRB3. , UuRB2-3, Uu RB2-2 and Uu RB2-1 belonging to UE2 are mapped (multiplexed) into Un RB2, UuRBl-3, Uu RB1-2 and Uu RB1-1 images belonging to UE1 (multiplexed) into UnRBl .

根据本发明实施例，对 UnRB 3、 UnRB2和 UnRBl执行第一级优先处理，即，管理 RB组之间对上行链路资源的共享；并分别地，对 Un RB 3所汇聚的 UuRB3-l、 UuRB3-2执行第二级优先处理，对 Un RB2所汇聚的 Uu RB2-3、 Uu RB2-2和 Uu RB2-1执行第二级优先处理，对 Un RBI所汇聚的 Uu RBl-3、 Uu RB1-2和 Uu RBl-1执行第二级优先处理，即，管理 Uu RB之间对这些 Uu RB 所属的 Un RB资源的共享。从而通过这两级优先处理而实现了回程链路上的上行链路速率控制。 According to the embodiment of the present invention, the first level priority processing is performed on the UnRB 3, the UnRB2, and the UnRB1, that is, the sharing of the uplink resources between the RB groups is managed; and the UuRB3-l aggregated by the Un RB 3, respectively. The UuRB3-2 performs the second-level priority processing, and performs the second-level priority processing on the Uu RB2-3, Uu RB2-2, and Uu RB2-1 aggregated by the Un RB2, and the Uu RBl-3 and Uu RB1 aggregated by the Un RBI. -2 and Uu RBl-1 perform second-level prioritization, that is, manage sharing of Un RB resources to which these Uu RBs belong between Uu RBs. The uplink rate control on the backhaul link is thus achieved by these two levels of priority processing.

图 4 示出了根据本发明第三实施例的回程链路上的上行链路速率控制的示意性框图。在本实施例中，采用所有对一映像。在这种情况下，对至少一个 UE 的 Uu RB按照特定规则而对应的 Uu RB组执行第一级优先处理；以及对每一个 Uu RB组中的 UuRB执行第二级优先处理。 4 is a schematic block diagram showing uplink rate control on a backhaul link in accordance with a third embodiment of the present invention. In this embodiment, all pairs of images are employed. In this case, the first level of priority processing is performed on the Uu RB group corresponding to the specific rule of the Uu RB of at least one UE; and the second level priority processing is performed on the Uu RB in each Uu RB group.

在所有对一映像下，所有的 Uu RB映像成一个 Un RB，由于只有一个 Un RB，所以不需要对 UnRB执行优先处理，然而在复用之前己然需要优先处理。因此，按照某一规则（例如，按照所属 UE、 QoS等级等）虚拟地将 UuRB分组。 Under all one-to-one mapping, all Uu RBs are mapped into one Un RB. Since there is only one Un RB, there is no need to perform priority processing on UnRB, but prior to multiplexing, priority processing is required. Therefore, UuRBs are virtually grouped according to a certain rule (e.g., according to the UE to which they belong, QoS class, etc.).

例如，如图 4所示，认为属于相同 UE的 Uu RB为一组。从而，根据本发明实施例，可以对以下 UuRB组进行第一级优先处理：由 UuRB3-2和 UuRB3-l 构成的 UuRB组，由 UuRB2-3、 UuRB2-2和 UuRB2-l构成的 UuRB组，以及由 UuRBl-3、 UuRBl-2和 UuRBl-1构成的 UuRB组，即，管理 UuRB组之间对上行链路资源的共享；并分别地，对每一个 UuRB组中的 UuRB执行第二级优先处理，即，管理 UuRB之间对这些 UuRB所属的 UuRB组资源的共享。从而通过执行两级优先处理，实现了回程链路上的上行链路速率控制。 For example, as shown in FIG. 4, Uu RBs belonging to the same UE are considered to be a group. Therefore, according to the embodiment of the present invention, the following priority processing may be performed on the following UuRB groups: a UuRB group composed of UuRB3-2 and UuRB3-l, and a UuRB group composed of UuRB2-3, UuRB2-2, and UuRB2-l, And a UuRB group consisting of UuRBl-3, UuRBl-2, and UuRBl-1, that is, managing sharing of uplink resources between UuRB groups; and separately performing second-level priority on UuRBs in each UuRB group Processing, that is, managing the sharing of UuRB group resources to which these UuRBs belong to the UuRB. The uplink rate control on the backhaul link is achieved by performing two levels of prioritization.

第四实施例 Fourth embodiment

图 5 示出了根据本发明第四实施例的回程链路上的上行链路速率控制的示意性框图。在本实施例中，采用一对一映像。在这种情况下，对至少一个 UE 的 Uu RB一对一映像成的 Un RB按照特定规则而对应的 Un RB组执行第一级优先处理；以及对每一个 Un RB组中的 Un RB执行第二级优先处理。 FIG. 5 shows an indication of uplink rate control on a backhaul link according to a fourth embodiment of the present invention. Intentional block diagram. In this embodiment, a one-to-one image is employed. In this case, the Un RB that is one-to-one mapped to the Uu RB of the at least one UE performs the first-level priority processing according to the Un RB group corresponding to the specific rule; and performs the execution of the Un RB in each Un RB group. Second-level priority processing.

如图 5所示，在一对一映像的情况下，每一个 Uu RB映像成相应的一个 Un RB。在这种情况下，虚拟地认为 Un RB按照某一规则（例如，按照所属的 UE 或按照 QoS等级）而属于一组，例如在本实施例中，认为属于相同 UE的 Un RB 为一组。那么根据本发明实施例，对属于 UE3的 Un RB (Un RB3-2和 Un RB3-l ) 所构成的 Un RB组、属于 UE2的 Un RB (Un RB2-3、 Un RB2-2和 Un RB2-1 ) 所构成的 Un RB组、以及属于 UE1的 Un RB(Un RBl-3、Un RB1-2和 Un RBl-1 ) 所构成的 Un RB组执行第一级优先处理， SP，管理 Un RB组之间对上行链路资源的共享；并分别地，对每一个 Un RB组中的 Un RB执行第二级优先处理，即，管理 Un RB之间对上行链路资源的共享。从而通过执行两级优先处理，实现了回程链路上的上行链路速率控制。 As shown in FIG. 5, in the case of a one-to-one mapping, each Uu RB is mapped into a corresponding Un RB. In this case, the Un RBs are considered to belong to a group according to a certain rule (for example, according to the UE to which they belong or according to the QoS class). For example, in the present embodiment, the Un RBs belonging to the same UE are considered as a group. Then, according to an embodiment of the present invention, an Un RB group composed of Un RBs (Un RB3-2 and Un RB3-l ) belonging to UE3 and Un RBs belonging to UE2 (Un RB2-3, Un RB2-2, and Un RB2-) 1) The Un RB group formed by the Un RB group and the Un RB (Un RBl-3, Un RB1-2, and Un RBl-1) belonging to UE1 performs the first-level priority processing, SP, and manages the Un RB group. Sharing of uplink resources between them; and separately performing second-level priority processing on Un RBs in each Un RB group, that is, managing sharing of uplink resources between Un RBs. Thus, uplink rate control on the backhaul link is achieved by performing two levels of priority processing.

上述第一至第四实施例中，通过采用两级优先处理，进一步细化了资源调度，从而提高了服务质量。如图 2至图 5所示，所有 RB组最终被 RN复用成上行链路共享信道（UL-SCH) 后发往 eNB。 In the above first to fourth embodiments, the resource scheduling is further refined by adopting two-level priority processing, thereby improving the quality of service. As shown in Figure 2 to Figure 5, all RB groups are finally multiplexed into the uplink shared channel (UL-SCH) by the RN and sent to the eNB.

此外，有利地，还可以在执行第一级优先处理之前，为每一个要执行第二级优先处理的 RB设置静态优先级和动态优先级，并根据各个 RB的静态优先级和动态优先级来分别计算出相应的、要执行第一级优先处理的 RB组的静态优先级和动态优先级。其中， RB的动态优先级的初始值被设置为该 RB的静态优先级值， RB的动态优先级在该 RB经历延迟的情况下提高，在该 RB获得传输资源的情况下降低，并且不低于该 RB的静态优先级； RB组的动态优先级根据该 RB 组中的 RB的动态优先级的变化而相应地变化；并且所述第一级优先处理是根据 RB组的动态优先级来执行的，所述第二级优先处理是根据 RB的动态优先级来执行的。通过这种动态优先级维持机制，使得在接入链路上发生延迟的业务可以优先地在回程链路上传输，从而补偿现由于重传等原因而造成的延迟。 In addition, advantageously, static priority and dynamic priority may be set for each RB to perform the second-level priority processing before performing the first-level priority processing, and according to the static priority and dynamic priority of each RB. The static priority and dynamic priority of the corresponding RB group to perform the first-level priority processing are respectively calculated. The initial value of the dynamic priority of the RB is set to the static priority value of the RB, and the dynamic priority of the RB is increased when the RB experiences a delay, and is reduced when the RB obtains the transmission resource, and is not low. The static priority of the RB; the dynamic priority of the RB group changes correspondingly according to the change of the dynamic priority of the RB in the RB group; and the first level priority processing is performed according to the dynamic priority of the RB group The second level priority processing is performed according to the dynamic priority of the RB. Through this dynamic priority maintenance mechanism, services that are delayed on the access link can be preferentially transmitted on the backhaul link, thereby compensating for delays due to retransmissions and the like.

图 6示出了根据本发明实施例的回程链路上的上行链路控制方法的流程图。如图 6所示，在步骤 601 , 为每一个要执行第二级优先处理的 RB设置静态参数。在本实施例中，所示静态参数可以包括静态优先级、优先处理比特率（PBR) 和漏桶大小持续时间（BSD)。静态优先级在 RB的整个生存期内是固定的，其值可以是例如整数 1到 16。在本实施例中假定 1代表最高优先级 16代表最低优先级。 6 shows a flow chart of an uplink control method on a backhaul link in accordance with an embodiment of the present invention. As shown in FIG. 6, in step 601, static parameters are set for each RB that is to perform the second level of priority processing. In this embodiment, the static parameters shown may include static priority, priority processing bit rate (PBR), and leaky bucket size duration (BSD). The static priority is fixed throughout the lifetime of the RB, and its value can be, for example, an integer of 1 to 16. It is assumed in the present embodiment that 1 represents the highest priority 16 represents the lowest priority.

在步骤 602，将每一个 RB的动态优先级设置为该 RB的静态优先级。 In step 602, the dynamic priority of each RB is set to the static priority of the RB.

动态优先级是临时值，其与静态优先级值具有相同的值范围（例如， 1到 16)。在步骤 603 , 可以通过对 RB组中的所有 RB的 PBR求和，来得到该 RB组的组优先处理比特率（GPBR), 并且类似地，可以通过对 RB组中的所有 RB的所有 RB的 BSD求和，来得到该 RB组的组漏桶大小持续时间（GBSD)。 Dynamic priority is a temporary value that has the same range of values as the static priority value (for example, 1 to 16). In step 603, the group priority processing bit rate (GPBR) of the RB group can be obtained by summing the PBRs of all the RBs in the RB group, and similarly, all the RBs of all the RBs in the RB group can be obtained. The BSD is summed to obtain the group leak bucket size duration (GBSD) of the RB group.

在步骤 604,根据各个 RB的静态优先级和动态优先级来分别计算出相应的、要执行第一级优先处理的 RB组的静态优先级和动态优先级。 In step 604, the static priority and the dynamic priority of the corresponding RB group to be processed in the first level are respectively calculated according to the static priority and the dynamic priority of each RB.

在本实施例中，例如可以通过对 RB组中的所有 RB的静态优先级求平均，来得到该 RB组的静态优先级，类似地，可以通过对 RB组中的所有 RB的动态优先级求平均，来得到该 RB组的动态优先级。 In this embodiment, the static priority of the RB group can be obtained by averaging the static priorities of all the RBs in the RB group. Similarly, the dynamic priority of all the RBs in the RB group can be obtained. On average, to get the dynamic priority of the RB group.

在步骤 605, 确定当前传输块（TB )是上行链路访问 TB还是上行链路回程 TB, 如果是上行链路访问 TB, 则执行步骤 606, 如果是上行链路回程 TB，则执行步骤 611。 In step 605, it is determined whether the current transport block (TB) is an uplink access TB or an uplink backhaul TB. If it is an uplink access TB, step 606 is performed, and if it is an uplink backhaul TB, step 611 is performed.

在步骤 606，对所有 Uu RB进行解复用。 At step 606, all Uu RBs are demultiplexed.

在步骤 607，确定 TB是否经历重传，如果是，则执行步骤 608，否则执行步骤 609。 At step 607, it is determined whether the TB is subjected to retransmission, and if so, step 608 is performed, otherwise step 609 is performed.

在步骤 608，将当前 TB中每个 RB的动态优先级提高。应注意，在本步骤中，要确保 RB的优先级被提高之后不能超过最高优先级，例如 RB的动态优先级值不能超过最高值 1。 At step 608, the dynamic priority of each RB in the current TB is increased. It should be noted that in this step, it is ensured that the priority of the RB cannot be increased beyond the highest priority. For example, the dynamic priority value of the RB cannot exceed the highest value of 1.

在步骤 609中，确定是否所有 RB都经过了上述处理，如果是，则执行步骤 610，否则返回步骤 607。 In step 609, it is determined whether all of the RBs have undergone the above processing, and if so, step 610 is performed, otherwise returning to step 607.

在步骤 610，重新计算每个 RB组的动态优先级，返回步骤 605。 At step 610, the dynamic priority of each RB group is recalculated, and the process returns to step 605.

在本步骤中，由于 RB的优先级可能以内重传而被改变，从而导致该 RB所属的 RB组的优先级也发生变化，因此需要重新计算 RB组的优先级，以确保第一优先处理和第二优先处理都是根据新的优先级来进行的。在步骤 611，根据 RB组的动态优先级来对所有 RB组执行第一级优先处理。例如，可以釆用相关参数（如，组优先级、组优先处理比特率（GPBR) 以及组漏桶大小持续时间（BGSD) )基于令牌漏桶算法在 RB组之间共享上行链路资源。 In this step, since the priority of the RB may be changed by the internal retransmission, the priority of the RB group to which the RB belongs also changes. Therefore, the priority of the RB group needs to be recalculated to ensure the first priority processing and The second priority processing is based on the new priority. At step 611, a first level of priority processing is performed on all RB groups based on the dynamic priority of the RB group. For example, related parameters (eg, group priority, group priority processing bit rate (GPBR), and group leaky bucket size duration (BGSD)) may be used to share uplink resources between RB groups based on a token leaky bucket algorithm.

在步骤 612, 确定一个 RB组是否获得传输资源，如果是，则执行步骤 613，否则执行步骤 616。 At step 612, it is determined whether an RB group obtains transmission resources, and if so, step 613 is performed, otherwise step 616 is performed.

在步骤 613，基于 RB的动态优先级来执行第二级优先处理。例如，可以通过令牌漏桶算法来实现第二级优先处理。 At step 613, the second level of priority processing is performed based on the dynamic priority of the RB. For example, the second level of priority processing can be implemented by the token leaky bucket algorithm.

例如，可以采用相关参数（如，优先级、优先处理比特率（PBR)和漏桶大小持续时间（BSD) ) 基于令牌漏桶算法在 RB之间共享 RB组资源。这些参数可以是由上层来配置的。可以根据 RB参数通过一些规则来计算 RB组控制参数，例如，组优先级可以是其 RB优先级的平均值， GPBR是其 RB PBR之和， GBSD 是其 RB BSD之和。此外， RB组的相关参数也可以由上层来配置。 For example, related parameters (e.g., priority, priority processing bit rate (PBR), and leaky bucket size duration (BSD)) may be used to share RB group resources between RBs based on the token leaky bucket algorithm. These parameters can be configured by the upper layer. The RB group control parameters may be calculated according to the RB parameters by some rules. For example, the group priority may be the average of its RB priorities, the GPBR is the sum of its RB PBRs, and the GBSD is the sum of its RB BSDs. In addition, the relevant parameters of the RB group can also be configured by the upper layer.

在步骤 614，将获得传输资源的每一个 RB的动态优先级降低。应注意，在本步骤中，应当确保 RB的动态优先级不能低于该 RB的静态优先级。例如，如果获得传输资源的 RB的动态优先级被降低将低于其静态优先级，则将该 RB的动态优先级强行设置为该 RB的静态优先级。 At step 614, the dynamic priority of each RB that obtained the transmission resource is reduced. It should be noted that in this step, it should be ensured that the dynamic priority of the RB cannot be lower than the static priority of the RB. For example, if the dynamic priority of the RB that obtained the transmission resource is lowered below its static priority, the dynamic priority of the RB is forcibly set to the static priority of the RB.

在步骤 615, 针对下一个 RB组执行步骤 612至步骤 614。 At step 615, steps 612 through 614 are performed for the next RB group.

在步骤 616，确定是否所有 RB组都经过了上述步骤 602至步骤 615的处理，如果是，则执行步骤 617, 否则返回步骤 612。 At step 616, it is determined whether all of the RB groups have undergone the processing of steps 602 through 615 above, and if so, step 617 is performed, otherwise step 612 is returned.

在步骤 617，将相关 RB复用成 TB。 At step 617, the associated RBs are multiplexed into TBs.

在步骤 608，重新计算每一个 RB组的动态优先级，返回步骤 605。 At step 608, the dynamic priority of each RB group is recalculated, and the process returns to step 605.

类似于步骤 610，由于 RB的优先级可能因为获得传输资源而降低，从而导致该 RB所属的 RB组的优先级也发生变化，因此需要重新计算 RB组的优先级，以确保第一优先处理和第二优先处理都是根据新的优先级来进行的。 Similar to the step 610, since the priority of the RB may be lowered due to the acquisition of the transmission resource, the priority of the RB group to which the RB belongs also changes. Therefore, the priority of the RB group needs to be recalculated to ensure the first priority processing and The second priority processing is based on the new priority.

图 7 示出了采用本发明的回程链路上的上行链路速率控制方案与现有技术的回程链路的上行链路速率控制方案的结果的对比图。如图 7所示，假定 UE之间的静态优先级关系为： UE3〉UE2=UE1。来自 UE1的业务因重传而发生延迟，在这种情况下根据本发明实施例其动态优先级提高，从而该延迟的业务可以被优先传输。因此，从图 7中可以看出，与现有技术相比，本发明实施例通过引入了动态优先级机制，使得可以有效地补偿由于重传或调用等原因而发生的延迟。由此可以看出，采用本发明实施例所提供的方法，通过执行两级优先处理而不是一级优先处理，使得服务质量可以得到提高。同时，由于引入了动态优先级，使得可以补偿由于重传或调用等原因而造成的延迟。 Figure 7 shows a comparison of the results of an uplink rate control scheme on a backhaul link employing the present invention and an uplink rate control scheme of a prior art backhaul link. As shown in FIG. 7, it is assumed that the static priority relationship between UEs is: UE3>UE2=UE1. The traffic from UE1 is delayed due to retransmission, in which case its dynamic priority is increased according to an embodiment of the present invention, so that the delayed traffic can be preferentially transmitted. Therefore, it can be seen from FIG. 7 that the embodiment of the present invention is introduced by comparison with the prior art. The dynamic priority mechanism makes it possible to effectively compensate for delays due to retransmissions or calls. It can be seen that the quality of service can be improved by performing two-level priority processing instead of first-level priority processing by using the method provided by the embodiment of the present invention. At the same time, due to the introduction of dynamic priority, it is possible to compensate for delays caused by retransmissions or calls.
