Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a data processing method, a base station, and a user equipment.
  • Long-term evolution (English term: Long Term Evolution, English abbreviation: LTE) is gradually developing from one independent site to the other.
  • Common technologies include: joint transmission of two cells (English name: joint transmission, English abbreviation: JT), single frequency network (English name: Single Frequency Network, English abbreviation: SFN), dynamic node selection (English full name: Dynamic Point Selection, English abbreviation: DPS), carrier aggregation (English full name: Carrier Aggregation, English abbreviation: CA), coordinated scheduling power control (English full name: Coordinated Scheduling-based Power Control, English abbreviation: CSPC).
  • inter-station interconnection An important basis for inter-station coordination is inter-station interconnection.
  • the commonly used methods include optical fiber interconnection and common Internet protocol (English full name: Internet Protocol, English abbreviation: IP) network interconnection.
  • IP Internet Protocol
  • the advantage of fiber optic interconnection is that the delay is small (for example, can reach 100 nanoseconds or less), but the engineering cost is high, and the operator who needs to lay the fiber in advance needs to re-lay the fiber.
  • IP interconnection is that the cost is low, and the existing transmission network can be utilized without special modification, but the delay of data transmission is large, and usually has a delay of 2 to 8 milliseconds.
  • the hybrid automatic repeat request English full name: Hybrid Automatic Repeat reQuest, English abbreviation: HARQ
  • Figure 1-a is a schematic diagram of the processing flow of delaying a HARQ process when inter-station transmission is not considered in the prior art.
  • the main steps may include the following steps:
  • Step 1 The secondary carrier cell (English full name: Secondary Carrier Cell, English abbreviation: SCC) delivers the downlink authorization to the user equipment (English name: User Equipment, English abbreviation: UE).
  • Authorization is the downlink authorization for HARQ process 0.
  • the UE demodulates the corresponding data in the frequency domain location of the authorization, and performs cyclic redundancy check (English full name: Cyclic Redundancy Check, English abbreviation: CRC) to obtain the test result.
  • cyclic redundancy check English full name: Cyclic Redundancy Check, English abbreviation: CRC
  • Step 2 After receiving the downlink grant from the UE for 4 milliseconds, the UE needs to feed back the downlink grant reception result of the HARQ process 0 corresponding to the 0 time to the base station.
  • Step 3 The base station receives the feedback of the HARQ process 0 through the primary carrier cell (English name: Primary Carrier Cell, English abbreviation: PCC), and performs demodulation processing.
  • PCC Primary Carrier Cell
  • Step 4 Since the inter-station transmission delay is not considered, after the demodulation is completed, the base station transmits the feedback of the HARQ process 0 to the SCC through the PCC at the same time. For example, the base station demodulates at 7 o'clock, and the base station sends feedback of HARQ process 0 to the SCC at time 7.
  • Step 5 At the new downlink scheduling moment, the SCC finds that the HARQ process 0 is available, and continues to use the HARQ process 0 to complete a downlink authorization.
  • Figure 1-b is a schematic diagram of the processing flow of delaying eight HARQ processes in the prior art without considering inter-station transmission. Among them, different arrow symbols indicate different HARQ processes.
  • Figure 1-b when there is no inter-station transmission delay, the feedback of each HARQ process can be timely fed back to the SCC, in the SCC.
  • the side can be scheduled to be scheduled every millisecond, and each HARQ process has a multiplexing gain.
  • the first three steps are similar to steps 1, 2, and 3 shown in Figure 1-a.
  • Step 4 Since the inter-station transmission delay is 4 milliseconds, the feedback information requires a delay of 4 milliseconds to feed back to the SCC. In the 8th, 9th, and 10th milliseconds, the SCC cannot be scheduled because there is no available HARQ process. Therefore, in the existing technical solution, as the transmission delay between stations increases, the waiting time of the HARQ process becomes longer, and the time that the user cannot be scheduled becomes longer, which causes waste of air interface resources.

Description

一种数据的处理方法和基站以及用户设备
本申请要求于2015年10月26日提交中国专利局、申请号为201510700640.8、发明名称为“一种数据的处理方法和基站以及用户设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种数据的处理方法和基站以及用户设备。
背景技术
长期演进(英文全称：Long Term Evolution，英文简称：LTE)网络正逐步从一个一个的独立站点，向站点之间相互协作快速发展。常见的技术有：两个小区联合发送(英文全称：joint transmission，英文简称：JT)、单频组网(英文全称：Single Frequency Network，英文简称：SFN)、动态节点选择(英文全称：Dynamic Point Selection，英文简称：DPS)、载波聚合(英文全称：Carrier Aggregation，英文简称：CA)、协调调度功率控制(英文全称：Coordinated Scheduling-based Power Control，英文简称：CSPC)等。
站间协同一个重要的基础是站间互联。目前常用的方法有光纤互联以及普通的互联网协议(英文全称：Internet Protocol，英文简称：IP)网络互联。其中，光纤互联的优点是时延小(例如可以达到100纳秒以下)，但是工程造价高，对于预先没有铺设光纤的运营商就需要重新铺光纤。IP互联的优点是成本低，可利用现有的传输网络，无需特殊改造，但是数据传输的时延大，通常有2～8毫秒的时延。当时延过大时会导致混合自动重传请求(英文全称：Hybrid Automatic Repeat reQuest，英文简称：HARQ)反馈不及时，从而会造成无法获得HARQ复用增益的问题。
在不考虑站间传输时延的情况下，一个HARQ进程的处理流程如图1-a所示，图1-a为现有技术中不考虑站间传输时延时一个HARQ进程的处理流程示意图，主要可包括如下步骤：
步骤1：辅载波小区(英文全称：Secondary Carrier Cell，英文简称：SCC)下发下行授权给用户设备(英文全称：User Equipment，英文简称：UE)，此 授权为HARQ进程0的下行授权。UE收到此授权后，在该授权中的频域位置去解调相应的数据，并进行循环冗余校验(英文全称：Cyclic Redundancy Check，英文简称：CRC)处理，得到检验结果。
步骤2：从UE接收到下行授权的4毫秒之后，UE需要将对应于0时刻的HARQ进程0的下行授权接收结果反馈给基站。
步骤3：基站通过主载波小区(英文全称：Primary Carrier Cell，英文简称：PCC)接收HARQ进程0的反馈，并进行解调处理。
步骤4：由于不考虑站间传输时延，基站在解调完成之后，基站在同一时刻通过PCC将HARQ进程0的反馈发送到SCC。例如基站在7时刻解调完成，基站在7时刻将HARQ进程0的反馈发送到SCC。
步骤5：在新的一次下行调度时刻，SCC发现HARQ进程0可用，继续使用HARQ进程0完成一次下行授权。
将上述流程扩展到全部8个HARQ进程的理想回传下，如图1-b所示，图1-b为现有技术中不考虑站间传输时延时8个HARQ进程的处理流程示意图，其中，不同箭头符号指示的是不同的HARQ进程，从图1-b可以看出，当不存在站间传输时延的情况下，每一个HARQ进程的反馈都能够及时的反馈到SCC，在SCC侧能满足每个毫秒都被调度，以及每个HARQ进程都有复用增益。
本发明的发明人在实现本发明的过程中发现，上述的现有技术只能应用于不存在站间传输时延的情况，而在实际的应用场景中，站间传输时延通常都会存在。当站间传输时延为非理想情况时，比如为4毫秒，处理流程如图1-c所示，图1-c为现有技术中考虑站间传输时延时8个HARQ进程的处理流程示意图，主要可包括如下步骤：
前3个步骤与图1-a所示的步骤1、步骤2、步骤3相类似。
步骤4：由于站间传输时延为4毫秒，导致反馈的信息需要4毫秒的延迟才能反馈到SCC，在第8、9、10毫秒，由于没有可用的HARQ进程，SCC无法调度。因此，在现有的技术方案中，随着站间传输时延的增大，HARQ进程的等待时间会变长，用户无法被调度的时间也会变长，这会造成空口资源的浪费。

具体实施方式
本发明实施例提供了一种数据的处理方法和基站以及用户设备，用于基站 之间存在站间传输时延时既能实现UE的满调度，又能实现HARQ进程的复用增益。
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本发明一部分实施例，而非全部实施例。基于本发明中的实施例，本领域的技术人员所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本发明的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
以下分别进行详细说明。
本发明数据的处理方法的一个实施例，可应用于基站侧使用HARQ进程向UE发送数据的场景中，请参阅图2所示，本发明一个实施例提供的数据的处理方法，可以包括：
201、第一基站在第一传输时间间隔(英文全称：Transmission Time Interval，英文简称：TTI)使用第一HARQ进程向UE发送第一下行授权和第一下行数据，第一下行数据携带有包括第一状态的第一新数据指示(英文全称：New Data Indicator，英文简称：NDI)。
在本发明实施例中，第一基站在一个TTI使用一个HARQ进程向UE发送下行授权以及下行数据。其中，为了区分不同的TTI，将本发明实施例中后续出现的不同TTI分别定义为：第一TTI、第二TTI、第三TTI、第四TTI、第五TTI、第六TTI等等，另外将第一基站在不同个TTI发送的各个下行授权也分别定义为：第一下行授权、第二下行授权、第三下行授权、第四下行授权、第五下行授权、第六下行授权等等。为了区别不同的下行数据，将本发明实施例中后续出现的不同下行数据分别定义为：第一下行数据、第二下行数据、第三下行数据、第四下行数据等等。同样的，本发明实施例中将不同的HARQ 进程对应的NDI也分别采用不同的定义方式，例如，将第一HARQ进程对应的NDI定义为第一NDI，将第二HARQ进程对应的NDI定义为第二NDI。
在本发明实施例中，第一基站将HARQ进程分为两类进程：第一HARQ进程和第二HARQ进程，第一HARQ进程在HARQ进程不够用时仅做HARQ进程的初传使用，用于保证UE的满调度，该第一HARQ进程也称之为普通HARQ进程。其中，满调度指的是UE在每一个TTI都收到一个下行授权，因此HARQ进程可以用于实现UE的满调度。第二HARQ进程在任何情况都保留HARQ复用增益，该第二HARQ进程也称之为复用HARQ进程。本发明实施例中利用两类HARQ进程的组合，达到既能满足满调度，又能获得HARQ复用增益的效果。举例说明如下，协议规定一共有8个HARQ进程，分别为0号、1号、2号、…、7号HARQ进程。其中，8个HARQ进程分成两类，0号HARQ进程是第一HARQ进程，1～7号是第二HARQ进程，1～7号HARQ进程会等待初传调度的反馈信息来决定是否重传，这样当1～7号HARQ进程出现初传失败时，可以实现重传，因此1～7号的第二HARQ进程有重传增益。由于站间传输时延的存在会导致1～7号HARQ进程从一个站反馈到另外一个站时有一定的时间差，这会导致UE在一定时间内没有可用的调度资源，在这种情况下，0号HARQ进程可以满足用户的满调度。不限定的是，在本发明的另一些实施例中，还可以将0号和1号HARQ进程作为第一HARQ进程，而将2～7号作为第二HARQ进程，还可以将0号、1号、2号HARQ进程作为第一HARQ进程，而将3～7号作为第二HARQ进程，具体实现方式可以根据应用场景来确定，此处仅作说明。
在本发明实施例中，每个HARQ进程有一个独自的NDI，在使用HARQ进程发送的下行数据都携带有一个NDI，该NDI可以包括两个状态，例如第一NDI包括：第一状态和第三状态，第二NDI包括：第二状态和第四状态。举例说明如下，NDI为1个比特，每个HARQ进程有一个独自的NDI，当本HARQ进程是初传的时候，HARQ翻转(例如从0翻转到1，或者从1翻转到0)，当本HARQ进程是重传的时候，NDI保持不变，不进行翻转。
需要说明的是，在本发明实施例中，第一基站使用第一HARQ进程向UE发送第一下行授权和第一下行数据可以是第一基站使用第一HARQ进程向UE发送第一下行授权，然后在第一下行授权指示的频域位置向UE发送第一下行 数据，则UE可以根据确定的第一下行授权来接收第一基站发送的第一下行数据。另外，第一基站发送第二下行授权、第三下行授权、第四下行授权、第五下行授权、第六下行授权来发送下行数据的情况与此相类似，不再逐一描述。
202、第一基站在第二TTI使用第二HARQ进程向UE发送第二下行授权和第二下行数据，第二下行数据携带有包括第二状态的第二NDI。
在本发明实施例中，前述步骤201中第一基站在第一TTI使用第一HARQ进程向UE发送第一下行授权和第一下行数据，步骤202中基站在不同于第一TTI的另一个时刻(定义为第二TTI)使用本发明实施例提供的第二HARQ进程向UE发送第二下行授权和第二下行数据，该第二下行数据携带有包括第二状态的第二NDI。其中，第二下行数据携带的第二NDI包括两种状态：第二状态和第四状态，在第二NDI中第二状态翻转可以得到第四状态，第四状态翻转可以得到第二状态。第二NDI用于指示UE本次HARQ进程的数据是初传还是重传，如果此值和第二HARQ进程对应的缓冲中保存的下行数据不一致，UE认为这是一次初传，否则认为是一次重传，若UE认为是一次重传，UE可以进行HARQ合并，获得HARQ进程的复用增益。在本发明实施例中，由前述内容描述可知，第一HARQ进程用于实现UE的满调度，第二HARQ进程用于实现HARQ进程的复用增益。因此通过步骤201和步骤202的描述可知，UE可以在两个不同的TTI分别使用两种不同的HARQ进程，则两类HARQ进程均可以用于向UE发送下行数据，通过两类HARQ进程既能保证满调度，又能获得HARQ复用增益。
203、第一基站在第三TTI使用第一HARQ进程向UE发送第三下行授权和第三下行数据，第三下行数据携带有包括第三状态的第一NDI，第一NDI的第一状态翻转后得到第三状态。
在本发明实施例中，由前述步骤201和步骤202可知，第一基站分别向UE发送了第一下行数据和第二下行数据，对于站间协作的实现场景中，例如载波聚合场景中，第一基站为SCC的基站，第二基站为PCC的基站。UE对第一下行数据进行接收，UE向第二基站发送第一下行数据对应的第一反馈结果，由第二基站再向第一基站发送该第一反馈结果。同样的，UE对第二下行数据进行接收，UE向第二基站发送第二下行数据对应的第二反馈结果，由第二基站再向第一基站发送该第二反馈结果。在两个基站的站间协作场景下，从 第二基站到第一基站之间必然会存在站间传输时延。因此当第一基站在第一TTI向UE发送第一下行数据之后，在第一基站未接收到第一反馈结果之前，第一基站没有可用的HARQ进程，为了实现UE的满调度，第一基站可以仍使用第一HARQ进程向UE发送下行数据。例如，第三TTI为第一TTI之后的一个TTI，在第三TTI假设第一基站还没有接收到第一反馈结果，第一基站为了满足UE的满调度，第一基站再使用第一HARQ进程向UE发送第三下行授权和第三下行数据。由步骤201可知，第一HARQ进程对应的第一NDI包括第一状态，在第一TTI之后的第三TTI再使用第一HARQ进程发送不同于第一下行数据的第三下行数据时，需要将第一HARQ进程对应的第一NDI进行状态翻转，即需要在第三下行数据携带有包括第三状态的第一NDI，第一NDI的第一状态翻转后得到第三状态。
在本发明的一些实施例中，第一基站在第一TTI向UE发送了第一下行数据，第一基站在第五TTI接收到第二基站发送的第一下行数据对应的第一反馈结果，其中第五TTI位于第一TTI之后，第五TTI也位于第三TTI之后，本发明实施例提供的数据的处理方法还可以包括如下步骤：
A1、第一基站在第五TTI接收第二基站发送的第一下行数据对应的第一反馈结果，第一基站根据第一反馈结果包括的否认(英文全称：Negative ACKnowledgment，英文简称：NACK)信息在第五TTI使用第一HARQ进程向UE发送第五下行授权和重传的第一下行数据，重传的第一下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态，第四TTI和第二TTI之间的时间差等于第五TTI和第一TTI之间的时间差。
其中，第一基站在第一TTI发送了第一下行数据之后，第一基站在第五TTI接收到第一反馈结果之前，第一基站为了满足UE的满调度，第一基站在第三TTI发送了第三下行数据，当第一基站在第五TTI接收到第一反馈结果之后，第一基站可以获取到UE对第一反馈结果的接收情况，即UE是否正确接收到第一下行数据，若UE正确接收到第一下行数据，第一反馈结果包括确认(英文名称：ACKnowledgment，英文简称：ACK)信息，若UE接收第一下行数据错误，第一反馈结果包括NACK信息，当第一反馈结果包括NACK信息时，第一基站需要向UE重传第一下行数据，即需要执行步骤A1，第一基站在第五TTI使用第一HARQ进程向UE发送第五下行授权和重传的第一下 行数据，重传的第一下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态。由步骤203可知，在第三TTI第一HARQ进程对应的第一NDI为第三状态，若执行步骤A1，则还需要对在第三TTI第一HARQ进程对应的第一NDI进行翻转，此时第一NDI翻转为第一状态。
需要说明的是，在本发明实施例中，第一HARQ进程用于实现UE的满调度，因此当第一基站没有收到第二基站发送的第一反馈结果之前，第一基站可以多次使用第一HARQ进行向UE发送新的下行数据，以实现UE的满调度。例如，在本发明的一些实施例中，步骤203第一基站在第三TTI使用第一HARQ进程向UE发送第三下行授权和第三下行数据之后，本发明实施例提供的数据的处理方法，还可以包括如下步骤：
B1、第一基站在第六TTI使用第一HARQ进程向UE发送第六下行授权和第四下行数据，第四下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态。
其中，在第一TTI之后除了存在第三TTI之外，还存在一个第六TTI，第六TTI为第三TTI之后的一个TTI，在第六TTI假设第一基站还没有接收到第一反馈结果，第一基站为了满足UE的满调度，第一基站再使用第一HARQ进程向UE发送第六下行授权和第四下行数据。由步骤203可知，在第三TTI，第一HARQ进程对应的第一NDI包括第三状态，在第三TTI之后的第六TTI再使用第一HARQ进程发送不同于第三下行数据的第四下行数据时，需要将第一HARQ进程对应的第一NDI进行状态翻转，即需要在第四下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态。
需要说明的是，在本发明实施例中，第一基站使用第一HARQ进程向UE发送了第一下行数据之后，在第一基站接收到第一下行数据对应的第一反馈结果之前，第一基站为了满足UE的满调度，可以多次使用第一HARQ进程向UE发送新的下行数据。
在本发明的一些实施例中，步骤203第一基站在第三TTI使用第一HARQ进程向UE发送第三下行授权和第三下行数据，具体可以包括如下步骤：
C1、若第一基站在第三TTI确定没有可用的HARQ进程时，第一基站在第三TTI使用虚拟HARQ进程向UE发送第三下行授权和第三下行数据，虚拟HARQ进程和第一HARQ进程相对应。
其中，由步骤201和步骤202可知，第一基站使用第一HARQ进程和第二HARQ进程分别发送了第一下行数据和第二下行数据，第一基站在第三TTI确定没有可用的HARQ进程，此时第一基站在第三TTI使用虚拟HARQ进程向UE发送第三下行授权和第三下行数据，虚拟HARQ进程和第一HARQ进程相对应。举例说明如下，在本发明实施例中，当站间传输时延导致第一基站的下行调度不满时，会虚拟出多个(以8个为例)HARQ进程，当第一基站的调度器发现没有可用的真实0～7HARQ进程后，会从虚拟的8～15HARQ进程中申请一个HARQ进程，然后按照一定的映射关系(例如取模的方式)映射到空口的真实HARQ进程。
204、第一基站在第四TTI接收第二基站发送的第二下行数据对应的第二反馈结果，第一基站根据第二反馈结果包括的NACK信息在第四TTI使用第二HARQ进程向UE发送第四下行授权和重传的第二下行数据，重传的第二下行数据携带有包括第二状态的第二NDI。
其中，第二基站和第一基站之间存在站间传输时延。
在本发明实施例中，第一基站在第二TTI向UE发送了第二下行数据，第一基站在第四TTI接收到第二基站发送的第二下行数据对应的第二反馈结果，其中第四TTI位于第二TTI之后，第四TTI位于第三TTI之后。第一基站在第二TTI发送了第二下行数据之后，第一基站在第四TTI接收到第二反馈结果之前，第一基站为了满足UE的满调度，第一基站在第三TTI发送了第三下行数据，当第一基站在第四TTI接收到第二反馈结果之后，第一基站可以获取到UE对第二反馈结果的接收情况，即UE是否正确接收到第二下行数据，若UE正确接收到第二下行数据，第二反馈结果包括ACK信息，若UE接收第二下行数据错误，第二反馈结果包括NACK信息，当第二反馈结果包括NACK信息时，第一基站需要向UE重传第二下行数据，即需要执行步骤204，第一基站在第四TTI使用第二HARQ进程向UE发送第四下行授权和重传的第二下行数据，重传的第二下行数据携带有包括第二状态的第二NDI，第二NDI的状态在第二TTI时为第二状态，由于在第四TTI第二HARQ进程需要重传第二下行数据，因此第二HARQ进程对应的第二NDI仍维持第二状态，UE根据在第四TTI时第二HARQ进程对应的第二NDI使用第二状态，UE可以确定第一基站向UE重传了第二下行数据。
在本发明的一些实施例中，步骤204中描述了第一基站接收到的第二反馈结果为NACK信息时第一基站的实现方式，那么当第二反馈结果为ACK信息时，本发明实施例提供的数据的处理方法还可以包括如下步骤：
D1、第一基站在第四TTI接收第二基站发送的第二下行数据对应的第二反馈结果之后，第一基站根据第二反馈结果包括的确认ACK信息在第四TTI使用第二HARQ进程向UE发送第四下行授权和第五下行数据，第五下行数据携带有包括第四状态的第二NDI，第二NDI的第二状态翻转后得到第四状态。
其中，若UE接收第二下行数据正确，第二反馈结果包括ACK信息，当第二反馈结果包括ACK信息时，第一基站可以向UE发送的新的下行数据，即需要执行步骤D1，第一基站在第四TTI使用第二HARQ进程向UE发送第四下行授权和第五下行数据，第五下行数据携带有包括第四状态的第二NDI，在第二TTI时第二HARQ进程对应的第二NDI为第二状态，在第四TTI传了新的下行数据，第二NDI的第二状态翻转后得到第四状态。
通过前述实施例对本发明的举例说明可知，第一基站在第一TTI使用第一HARQ进程向UE发送第一下行授权和第一下行数据，第一下行数据携带有包括第一状态的第一NDI；第一基站在第二TTI使用第二HARQ进程向UE发送第二下行授权和第二下行数据，第二下行数据携带有包括第二状态的第二NDI；第一基站在第三TTI使用第一HARQ进程向UE发送第三下行授权和第三下行数据，第三下行数据携带有包括第三状态的第一NDI，第一NDI的第一状态翻转后得到第三状态；第一基站在第四TTI接收第二基站发送的第二下行数据对应的第二反馈结果，第一基站根据第二反馈结果包括的否认NACK信息在第四TTI使用第二HARQ进程向UE发送第四下行授权和重传的第二下行数据，重传的第二下行数据携带有包括第二状态的第二NDI，第二基站和第一基站之间存在的站间传输时延为第四TTI和第一TTI之间的时间差。本发明实施例中，第一基站将HARQ进程分为两类进程：第一HARQ进程和第二HARQ进程，第一HARQ进程可以用于第一基站在第一TTI和第三TTI向UE发送下行数据，可以实现UE的满调度，因此可以提供对空口资源的利用率。在第一基站和第二基站之间存在站间传输时延的情况下，第一基站在第四TTI接收到第二反馈结果，第一基站使用第二HARQ进程对第二下行数据进行重 传，由于重传的第二下行数据中携带的第二NDI的状态并没有翻转(即第二NDI仍包括第二状态)，因此UE可以根据包括第二状态的第二NDI对第一基站在第二TTI发送的第二下行数据和第四TTI发送的重传的第二下行数据进行共同解码，因此第二HARQ进程可以实现HARQ进程的复用增益。
前述实施例从第一基站侧描述了本发明实施例提供的数据的处理方法，接下来从与第一基站交互的UE侧来描述本发明实施例提供的数据的处理方法，请参阅如图3所示，为本发明实施例提供的另一种数据的处理方法，具体可以包括如下步骤：
301、UE在第一TTI使用第一HARQ进程接收第一基站发送的第一下行授权，以及根据第一下行授权解调第一基站发送的第一下行数据，向第二基站发送与第一下行数据对应的第一反馈结果，第二基站和第一基站之间存在站间传输时延，第一下行数据携带有包括第一状态的第一NDI。
在本发明实施例中，第一基站在第一TTI使用第一HARQ进程向UE发送了第一下行授权，UE在第一TTI使用第一HARQ进程接收第一下行授权，UE从第一下行授权确定第一基站发送第一下行数据的频域位置，然后UE根据第一下行授权解调第一下行数据，UE根据对第一下行数据的接收情况生成第一反馈结果，然后向第二基站发送与第一下行数据对应的第一反馈结果。举例说明如下，若UE正确接收到第一下行数据，第一反馈结果包括ACK信息，若UE接收第一下行数据错误，第一反馈结果包括NACK信息。另外UE可以根据第一下行数据中携带的第一NDI的状态来确定第一基站是初传第一下行数据还是重传第一下行数据。
在本发明实施例中，第一基站将HARQ进程分为两类进程：第一HARQ进程和第二HARQ进程，第一HARQ进程在HARQ进程不够用时仅做HARQ进程的初传使用，用于保证UE的满调度，该第一HARQ进程也称之为普通HARQ进程。其中，满调度指的是UE在每一个TTI都收到一个下行授权，因此HARQ进程可以用于实现UE的满调度。第二HARQ进程在任何情况都保留HARQ复用增益，该第二HARQ进程也称之为复用HARQ进程。本发明实施例中利用两类HARQ进程的组合，达到既能满足满调度，又能获得HARQ复用增益的效果。举例说明如下，协议规定一共有8个HARQ进程，分别为0号、1号、2号、…、7号HARQ进程。其中，8个HARQ进程分成两类，0 号HARQ进程是第一HARQ进程，1～7号是第二HARQ进程，1～7号HARQ进程会等待初传调度的反馈信息来决定是否重传，这样当1～7号HARQ进程出现初传失败时，可以实现重传，因此1～7号的第二HARQ进程有重传增益。由于站间传输时延的存在会导致1～7号HARQ进程从一个站反馈到另外一个站时有一定的时间差，这会导致UE在一定时间内没有可用的调度资源，在这种情况下，0号HARQ进程可以满足用户的满调度。
302、UE在第二TTI使用第二HARQ进程接收第一基站发送的第二下行授权，以及根据第二下行授权解调第一基站发送的第二下行数据，向第二基站发送与第二下行数据对应的第二反馈结果，第二下行数据携带有包括第二状态的第二NDI。
在本发明实施例中，第一基站在第二TTI使用第二HARQ进程向UE发送了第二下行授权，UE在第二TTI使用第二HARQ进程接收第二下行授权，UE从第二下行授权确定第一基站发送第二下行数据的频域位置，然后UE根据第二下行授权解调第二下行数据，UE根据对第二下行数据的接收情况生成第二反馈结果，然后向第一基站发送与第二下行数据对应的第二反馈结果。举例说明如下，若UE正确接收到第二下行数据，第二反馈结果包括ACK信息，若UE接收第二下行数据错误，第二反馈结果包括NACK信息。另外UE可以根据第二下行数据中携带的第二NDI的状态来确定第一基站是初传第二下行数据还是重传第二下行数据。
其中，第二下行数据携带的第二NDI包括两种状态：第二状态和第四状态，在第二NDI中第二状态翻转可以得到第四状态，第四状态翻转可以得到第二状态。第二NDI用于指示UE本次HARQ进程的数据是初传还是重传，如果此值和第二HARQ进程对应的缓冲中保存的下行数据不一致，UE认为这是一次初传，否则认为是一次重传，若UE认为是一次重传，UE可以进行HARQ合并，获得HARQ进程的复用增益。在本发明实施例中，由前述内容描述可知，第一HARQ进程用于实现UE的满调度，第二HARQ进程用于实现HARQ进程的复用增益。因此通过步骤301和步骤302的描述可知，UE可以在两个不同的TTI分别使用两种不同的HARQ进程，则两类HARQ进程均可以用于向UE发送下行数据，通过两类HARQ进程既能保证满调度，又能获得HARQ复用增益。
303、UE在第三TTI使用第一HARQ进程接收第一基站发送的第三下行授权，以及根据第三下行授权解调第一基站发送的第三下行数据，向第二基站发送与第三下行数据对应的第三反馈结果，第三下行数据携带有包括第三状态的第一NDI。
在本发明实施例中，UE对第一下行数据进行接收，UE向第二基站发送第一下行数据对应的第一反馈结果，由第二基站再向第一基站发送该第一反馈结果。同样的，UE对第二下行数据进行接收，UE向第二基站发送第二下行数据对应的第二反馈结果，由第二基站再向第一基站发送该第二反馈结果。在两个基站的站间协作场景下，从第二基站到第一基站之间必然会存在站间传输时延。因此当第一基站在第一TTI向UE发送第一下行数据之后，在第一基站未接收到第一反馈结果之前，第一基站没有可用的HARQ进程，为了实现UE的满调度，第一基站可以仍使用第一HARQ进程向UE发送下行数据。例如，第三TTI为第一TTI之后的一个TTI，在第三TTI假设第一基站还没有接收到第一反馈结果，第一基站为了满足UE的满调度，第一基站再使用第一HARQ进程向UE发送第三下行授权和第三下行数据。在第一TTI第一HARQ进程对应的第一NDI包括第一状态，在第一TTI之后的第三TTI再使用第一HARQ进程发送不同于第一下行数据的第三下行数据时，需要将第一HARQ进程对应的第一NDI进行状态翻转，即需要在第三下行数据携带有包括第三状态的第一NDI，第一NDI的第一状态翻转后得到第三状态。
在本发明实施例中，第一基站在第三TTI再次使用第一HARQ进程向UE发送了第三下行授权，UE在第三TTI使用第一HARQ进程接收第三下行授权，UE从第三下行授权确定第一基站发送第三下行数据的频域位置，然后UE根据第三下行授权解调第三下行数据，UE根据对第三下行数据的接收情况生成第三反馈结果，然后向第一基站发送与第三下行数据对应的第三反馈结果。
在本发明的一些实施例中，步骤302执行之后，本发明实施例提供的数据的处理方法还包括如下步骤：
D1、UE在第五TTI使用第一HARQ进程接收第一基站发送的第五下行授权，以及根据第五下行授权解调第一基站发送的重传的第一下行数据，重传的第一下行数据携带有包括第一状态的第一NDI。
其中，第一基站在第一TTI发送了第一下行数据之后，第一基站在第五 TTI接收到第一反馈结果之前，第一基站为了满足UE的满调度，第一基站在第三TTI发送了第三下行数据，当第一基站在第五TTI接收到第一反馈结果之后，第一基站可以获取到UE对第一反馈结果的接收情况，即UE是否正确接收到第一下行数据，若UE正确接收到第一下行数据，第一反馈结果包括确认(英文名称：ACKnowledgment，英文简称：ACK)信息，若UE接收第一下行数据错误，第一反馈结果包括NACK信息，当第一反馈结果包括NACK信息时，第一基站需要向UE重传第一下行数据，即需要执行步骤A1，第一基站在第五TTI使用第一HARQ进程向UE发送第五下行授权和重传的第一下行数据，重传的第一下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态。由步骤203可知，在第三TTI第一HARQ进程对应的第一NDI为第三状态，若执行步骤A1，则还需要对在第三TTI第一HARQ进程对应的第一NDI进行翻转，此时第一NDI翻转为第一状态。
在本发明的一些实施例中，步骤303UE在第三TTI使用第一HARQ进程接收第一基站发送的第三下行授权，具体可以包括如下步骤：
E1、UE在第三TTI使用虚拟HARQ进程接收第一基站发送的第三下行授权，虚拟HARQ进程和第一HARQ进程相对应。
其中，第一基站使用第一HARQ进程和第二HARQ进程分别发送了第一下行数据和第二下行数据，第一基站在第三TTI确定没有可用的HARQ进程，此时第一基站在第三TTI使用虚拟HARQ进程向UE发送第三下行授权和第三下行数据，虚拟HARQ进程和第一HARQ进程相对应。举例说明如下，在本发明实施例中，当站间传输时延导致第一基站的下行调度不满时，会虚拟出多个(以8个为例)HARQ进程，当第一基站的调度器发现没有可用的真实0～7HARQ进程后，会从虚拟的8～15HARQ进程中申请一个HARQ进程，然后按照一定的映射关系(例如取模的方式)映射到空口的真实HARQ进程。
在本发明的一些实施例中，步骤303中的根据第三下行授权解调第一基站发送的第三下行数据，可包括如下实现方式：
UE根据第三下行授权指示的空口资源接收第三下行数据；
UE根据第三下行数据携带的包括第三状态的第一NDI将第一HARQ进程对应的缓存中存储的第一下行数据清空，并将第三下行数据写入第一HARQ进程对应的缓存。
其中，UE在第三TTI使用第一HARQ进程接收第三下行授权，UE获取第三下行授权指示的空口资源，通过该空口资源可以确定第三下行数据发送的频域位置，然后UE根据第三下行授权解调第三下行数据，在第一TTI时，第一HARQ进程对应的第一NDI的状态为第一状态，若第三下行数据携带有包括第三状态的第一NDI。则说明在第三TTI时第一HARQ进程对应的第一NDI的状态已经翻转，UE确定此时第一基站发送的是新的下行数据，因此第一HARQ进程对应的缓存中存储的第一下行数据清空。
304、UE在第四TTI使用第二HARQ进程接收第一基站发送的第四下行授权，以及根据第四下行授权解调第一基站发送的重传的第二下行数据，向第二基站发送与重传的第二下行数据对应的第四反馈结果，重传的第二下行数据携带有包括第二状态的第二NDI。
在本发明实施例中，第四TTI位于第二TTI之后，并且第四TTI位于第三TTI之后。第一基站在第二TTI发送了第二下行数据之后，第一基站在第四TTI接收到第二反馈结果之前，第一基站为了满足UE的满调度，第一基站在第三TTI发送了第三下行数据。步骤302中UE向第二基站发送了第二下行数据对应的第二反馈结果，则第二基站接收该第二反馈结果，第二基站向第一基站转发第二反馈结果，由于第二基站和第一基站之间存在站间传输时延，当第一基站在第四TTI接收到第二反馈结果之后，第一基站根据第二反馈结果为NACK在第四TTI向UE发送重传的第二下行数据。UE在第四TTI使用第二HARQ进程接收第一基站发送的第四下行授权，以及根据第四下行授权解调第一基站发送的重传的第二下行数据，向第二基站发送与重传的第二下行数据对应的第四反馈结果，重传的第二下行数据携带有包括第二状态的第二NDI。第二NDI的状态在第二TTI时为第二状态，由于在第四TTI第二HARQ进程需要重传第二下行数据，因此第二HARQ进程对应的第二NDI仍维持第二状态，UE根据在第四TTI时第二HARQ进程对应的第二NDI使用第二状态，UE可以确定第一基站向UE重传了第二下行数据。
在本发明的一些实施例中，步骤304UE在第四TTI使用第二HARQ进程接收第一基站发送的第四下行授权之前，本发明实施例提供的数据的处理方法还包括如下步骤：
F1、UE在第六TTI使用第一HARQ进程接收第一基站发送的第六下行授 权，以及根据第六下行授权解调第一基站发送的第四下行数据，第四下行数据携带有包括第一状态的第一NDI。
其中，在第一TTI之后除了存在第三TTI之外，还存在一个第六TTI，第六TTI为第三TTI之后的一个TTI，在第六TTI假设第一基站还没有接收到第一反馈结果，第一基站为了满足UE的满调度，第一基站再使用第一HARQ进程向UE发送第六下行授权和第四下行数据，UE在第六TTI使用第一HARQ进程接收第一基站发送的第六下行授权，以及根据第六下行授权解调第一基站发送的第四下行数据。在第三TTI，第一HARQ进程对应的第一NDI包括第三状态，在第三TTI之后的第六TTI再使用第一HARQ进程发送不同于第三下行数据的第四下行数据时，需要将第一HARQ进程对应的第一NDI进行状态翻转，即需要在第四下行数据携带有包括第一状态的第一NDI，第一NDI的第三状态翻转后得到第一状态。
需要说明的是，在本发明实施例中，第一基站使用第一HARQ进程向UE发送了第一下行数据之后，在第一基站接收到第一下行数据对应的第一反馈结果之前，第一基站为了满足UE的满调度，可以多次使用第一HARQ进程向UE发送新的下行数据。
在本发明的一些实施例中，步骤304中描述了UE发送的第二反馈结果为NACK时UE在第四TTI接收重传的第二下行数据的实现方式，那么当第二反馈结果为ACK信息时，本发明实施例提供的数据的处理方法还可以包括如下步骤：
G1、UE在第四TTI使用第二HARQ进程接收第一基站发送的第四下行授权之后，UE根据第四下行授权解调第一基站发送的第五下行数据，第五下行数据携带有包括第四状态的第二NDI。
其中，若UE接收第二下行数据正确，第二反馈结果包括ACK信息，当第二反馈结果包括ACK信息时，第一基站可以向UE发送的新的下行数据(即第五下行数据)，此时需要执行步骤G1，UE在第四TTI使用第二HARQ进程接收第一基站发送的第四下行授权之后，UE根据第四下行授权解调第一基站发送的第五下行数据，第五下行数据携带有包括第四状态的第二NDI，在第二TTI时第二HARQ进程对应的第二NDI为第二状态，在第四TTI传了新的下行数据，第二NDI的第二状态翻转后得到第四状态。
在本发明的一些实施例中，步骤304中的根据第四下行授权解调第一基站发送的重传的第二下行数据，可包括如下实现方式：
UE根据第四下行授权指示的空口资源接收重传的第二下行数据；
UE根据重传的第二下行数据携带的包括第二状态的第二NDI，将第二HARQ进程对应的缓存中存储的第二下行数据和重传的下行数据进行合并，并将合并后的结果写入第一HARQ进程对应的缓存。
其中，UE在第四TTI使用第二HARQ进程接收第四下行授权，UE获取第四下行授权指示的空口资源，通过该空口资源可以确定重传的第二下行数据发送的频域位置，然后UE根据第四下行授权解调重传的第二下行数据，在第二TTI时，第二HARQ进程对应的第二NDI的状态为第二状态，若重传的第二下行数据携带有包括第二状态的第二NDI，则说明在第四TTI时第二HARQ进程对应的第二NDI的状态没有翻转，UE确定此时第一基站发送的是重传的第二下行数据，因此将第二HARQ进程对应的缓存中存储的第二下行数据和重传的第二下行数据进行合并，从而可以取得HARQ进程的复用增益。
通过前述实施例对本发明的举例说明可知，本发明实施例中，第一基站将HARQ进程分为两类进程：第一HARQ进程和第二HARQ进程，第一HARQ进程可以用于第一基站在第一TTI和第三TTI向UE发送下行数据，可以实现UE的满调度，因此可以提供对空口资源的利用率。在第一基站和第二基站之间存在站间传输时延的情况下，第一基站在第四TTI接收到第二反馈结果，第一基站使用第二HARQ进程对第二下行数据进行重传，由于重传的第二下行数据中携带的第二NDI的状态并没有翻转(即第二NDI仍包括第二状态)，因此UE可以根据包括第二状态的第二NDI对第一基站在第二TTI发送的第二下行数据和第四TTI发送的重传的第二下行数据进行共同解码，因此第二HARQ进程可以实现HARQ进程的复用增益。
为便于更好的理解和实施本发明实施例的上述方案，下面举例相应的应用场景来进行具体说明。
接下来以CA场景中两个基站之间进行站间协作传输为了进行说明，其中，第一基站为SCC所在的基站，第二基站为PCC所在的基站。请参阅如图4所示，为本发明实施例中考虑站间传输时延时一个HARQ进程的处理流程示 意图。本发明实施例采用一种新的HARQ分配方案。本发明实施例应用于在站间时延大的需要协作的场景，既可以做到满调度，又可以保证获得HARQ复用增益，本发明实施例既能保证满调度，又能获得HARQ复用增益，接下来进行举例说明。
本发明实施例中将HARQ进程分为两类：第一HARQ进程和第二HARQ进程，第一HARQ进程为普通HARQ进行，用来保证能进行满调度，第二HARQ进程为复用HARQ进程，用来获得HARQ复用增益。普通HARQ的用途是当SCC的L2调度器发现无法申请到复用HARQ时使用，用于维持UE满调度，复用HARQ的用途是根据反馈的ACK/NACK信息，进行重传或初传，获取复用增益用，复用HARQ进程一定有重传增益。
接下来以共有0-7号共8个HARQ进程为例，具体的，对其中的HARQ进程0和1进行说明，进程0为普通HARQ进程，进程1为复用HARQ进行，其他的HARQ进程均为等待反馈状态，是不可用的进程。
如图4所示，主要包括如下步骤：
步骤1：在TTI 0，SCC L2调度器申请HARQ进程0成功，并调度UE。UE收到此数据并解调。
步骤2：在TTI 1，SCC L2调度器申请HARQ进程1成功，并调度UE。UE收到此数据并解调。
步骤3：在TTI 4，UE发送HARQ进程0的反馈结果到PCC，PCC收到并开始解调。
步骤4：在TTI 5，UE发送HARQ进程1的反馈结果到PCC，PCC收到并开始解调。
步骤5：在TTI 7，PCC解调出HARQ进程0的结果，这里假设为NACK，同时将此结果发往SCC。
步骤6：在TTI 8，SCC L2调度器申请HARQ进程，但是所有的HARQ进程都被使用，无空闲的资源可用，SCC L2调度器申请普通HARQ进程0，对应虚拟HARQ进程8，用来满足满调度，同时NDI翻转。UE在此刻收到此调度后，清空HARQ进程0上的缓冲，使用新的数据替代，从图4可以看出之前HARQ进程0号在0毫秒的数据被新的进程0号在8毫秒的数据替代。
步骤7：在TTI8，PCC解调出HARQ进程1的反馈结果，这里假设为 NACK，同时将此结果发往SCC。
步骤8：在TTI 9，SCC L2调度器申请HARQ进程，但是所有的HARQ进程都被使用，无空闲的资源可用，于是SCC L2调度器申请普通HARQ进程0，对应虚拟HARQ进程9，用来满足满调度，同时NDI翻转。UE在此刻收到此调度后，清空HARQ进程0上的缓冲，使用新的数据替代，从图4可以看出HARQ进程0号在8毫秒的数据被新的进程0号在9毫秒的数据替代。
步骤9：在TTI 10，SCC L2调度器申请HARQ进程，但是所有的HARQ进程都被使用，无空闲的资源可用，于是SCC L2调度器申请普通HARQ进程0，对应虚拟HARQ进程10，用来满足满调度，同时NDI翻转。UE在此刻收到此调度后，清空HARQ进程0上的缓冲，使用新的数据替代，从图4可以看出HARQ进程0号在9毫秒的数据被新的进程0号在10毫秒的数据替代。
步骤10：在TTI11，SCC L2收到PCC反馈的0号HARQ进程在TTI 0时刻的解调信息，由于此时反馈的值为NACK，SCC L2调度器需要进行重传，由于HARQ进程0已经无法重传了，因此，此次重转仅能当做初传来处理，翻转NDI，丢失了重传增益。
步骤11：在TTI12，SCC L2收到PCC反馈的1号HARQ进程在TTI 1时刻的解调信息，由于此时反馈的值为NACK，SCC L2调度器需要进行重传，此时，按照HARQ复用增益方案，申请HARQ进程1，同时NDI不翻转，UE收到此数据后，会同在TTI1时刻收到的数据进行合并，这样，HARQ进程1获得了复用增益。
通过前述对本发明的举例说明可知，针对现有技术不能同时保证满调度和HARQ复用增益的问题，本发明实施例灵活的将HARQ进程分类，根据两类HARQ进程不同的作用，从而实现了既能满调度，又能获得HARQ复用增益的方法。对于普通HARQ进程和复用HARQ进程，可以分别设置初传误码率(英文全称：Initial Block Error Rate，英文简称：IBLER)。普通HARQ进程可以设置为1％的IBLER，以增加第一次传输正确的几率，复用HARQ进程设置同现有的默认参数一致，保留HARQ复用增益。普通HARQ进程的IBLER设置为1％的目的是为了保证99％的情况下初传都传输正确。需要说明的是，上述普通HARQ进程的IBLER是灵活可配，例如普通HARQ进程的IBLER 还是可以设置为5％、10％等多种情况，具体此处不做限定。
需要说明的是，在本发明的前述举例说明以跨站CA的场景为例，可以理解的是，只要两个基站或者更多的基站之间存在站间传输时延，都可以使用本发明实施例前述的数据的处理方法，例如也可以用于DPS、JT、SFN等需要站间交互ACK/NACK的特性。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
