Description

一种数据处理方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种数据处理方法及装置。
背景技术
无线保真(Wireless Fidelity，WiFi)是一种基于电气和电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)的IEEE802.11标准的无线局域网技术，实现将个人电脑(PersonalComputer，PC)、用户设备(User Equipment，UE)等终端以无线方式组成计算机网络。WiFi设备可包括接入点(Access Point，AP)和用户站点(简称：站点(Station，STA))，接入点与站点之间的通信链路称为非直连链路。为了提高带宽的使用效率，IEEE802.11标准规定了直连链路技术，即站点与站点之间的通信链路之间不需要通过接入点，但是在同一时间内仅允许一对直连链路站点进行通信。示例的，如图1所示，典型的直连链路与非直连链路的应用场景包括第一站点1、第二站点2、第三站点3、第四站点4、第五站点5、第六站点6和接入点AP1。第一站点1与第二站点2之间为直连链路；第三站点3与第四站点4之间为直连链路；第五站点5与第六站点6分别与接入点建立非直连链路。其中第一站点与第二站点虽然连接到AP1接受接入点的控制，但它们通信时通过直连链路进行，不需要经接入点转发。而第五站点和第六站点通信时则因为未建立直连链路而必须经接入点转发。
面向未来的高密集场景，IEEE拟建立新一代IEEE802.11增补标准，将引入OFDMA(Orthogonal Frequency-Division Multiple Access)技术，该OFDMA技术的使用可以提升带宽资源使用效率。OFDMA技术将传输带宽划分成正交的互不重叠的一系列子载波集，将不同的子载波集分配给不同的站点使用，从而实现接入点可以同时与多个站点进行通信。同时，OFDMA技术可动态地把可用带宽资 源分配给需要的站点，实现***资源的优化利用。根据数据传输方向的不同，又可分为接入点向站点传输数据为DL-OFDMA(Downlink-OFDMA，下行OFDMA)技术，站点向接入点传输数据为UL-OFDMA(Uplink-OFDMA，上行OFDMA)技术。DL-OFDMA技术可通过占用互不重叠的子载波集实现接入点向多个站点同时发送数据。同样，UL-OFDMA可实现多个站点向接入点同时发送数据。由于子载波等链路资源将实现动态分配，所以在建立基于OFDMA的非直连链路之前，接入点需要事先告知站点所分配的资源信息才能进行通信。资源分配信息可以通过物理头(PHY Header)和媒体接入控制(Media Access Control，MAC)层部分携带。
IEEE拟建立的新一代IEEE802.11增补标准或将对原有直连链路部分进行增强，以进一步适应未来高密集场景。目前一种直连链路的增强方案提出在DL-OFDMA或UL-OFDMA的非直连链路调度周期内同时调度直连链路，实现直连链路与非直连链路共存，同时尽可能减少直连链路对非直连链路的影响。而且也需要接入点事先发送直连链路资源分配记录，以便直连链路站点能够按照分配的资源进行直连通信。资源分配信息中使用站点的标识(例如关联标识)和直连链路的标识来指示资源分配对象。但是，为了减少资源分配信息的长度，资源分配信息中站点的标识和直连链路的标识会通过截短的方法来表示，例如IEEE802.11ac标准中资源分配信息仅分配8个比特的字段来表示原为16个比特的站点标识，因而一条资源分配信息是属于一个非直连的站点还是直连通信的站点就容易发生歧义，而增加额外的字段或信息位来指示这个信息势必增加开销，与尽可能减少资源分配信息的长度相违背。

具体实施方式
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，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
现有技术提供一种非直连链路资源分配记录结构示意图，如图2所示，包括物理层前导序列11(PHY Preamble)、站点标识字段12(STA ID)、正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)子载波资源字段13和数据传输速率字段14。所述数据传输速率字段可以是调制编码方案(Modulation and Coding Scheme，MCS)字段。每一种调制编码方案实质上都对应一种数据传输速率。非直连链路资源分配记录中，某些字段可能存在保留取值空间，例如，数据传输速率字段，IEEE802.11ac中数据传输速率字段为4比特，该4比特的数据传输速率字段可指示16种数据传输速率，但实际上仅使用10种数据传输速率。
本发明实施例提供一种数据处理方法，应用于接入点，如图3所示，包括：
步骤101、接入点生成资源分配信息。
所述资源分配信息包含多条资源分配记录，每条所述资源分配记录包含链路类型识别信息、链路标识信息和信道资源信息。
其中，当一条资源分配记录中的所述链路类型识别信息取第一范围值时，所述资源分配记录中所述链路标识信息包含一个非直连链路站点的站点标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述非直连链路站点与所述接入点通信时的数据传输速率，所述资源分配记录中所述信道资源信息用于指示所述非直连链路站点与所述接入点通信所需的信道资源，
当一条资源分配记录中的所述链路类型识别信息取第二范围值时，所述资源分配记录中所述链路标识信息包含一个直连链路标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述资源分配记录是直连链路站点进行直连通信的资源分配记录，所述资源分配记录中所述信道资源信息用于指示所述直连链路站点进行直连通信所需的信道资源；
所述第二范围值的取值空间在所述第一范围值以外，其可以是一个值，即此时所述链路类型识别信息的取值可以是一个固定的值。所述第二范围值也可以是一个取值区间，即此时所述链路类型识别信息的取值可以不是一个固定的值，可以是该取值区间内的任一个值。
步骤102、向站点发送所述资源分配信息，以便于所述非直连链路站点的站点标识指示的站点进行非直连通信或所述直连链路标识指示的站点进行直连通信。
一个站点可以是直连链路站点或非直连链路站点，直连链路站点可根据所述资源分配记录进行直连通信和/或非直连通信。非直连链路站点在本实施例场景中只根据所述资源分配记录进行非直连通信。
这样一来，所述直连链路的资源分配记录在格式上复用所述非直连链路的资源分配记录格式，通过资源分配记录中的链路类型识别信息取第一范围值或第二范围值来指示资源分配记录是直连链路资源分配记录还是非直连链路资源分配记录，同时还将链路类型识别信息的第一范围值用于指示非直连通信所必需的传输速率信息，避免额外增加一个字段作为链路类型的识别信息，有效地降低了资源分配信息的长度，提高了带宽的使用率。
本发明实施例提供一种数据处理方法，应用于直连链路站点，所述直连链路站点是指已经建立直连链路的站点，所述直连链路站点也可以同时与接入点建立非直连链路，如图4所示，包括：
步骤201、接收接入点发送的资源分配信息。
所述资源分配信息包含多条资源分配记录，每条所述资源分配记录包含链路类型识别信息、链路标识信息和信道资源信息。
其中，当一条资源分配记录中的所述链路类型识别信息取第一范围值时，所述资源分配记录中所述链路标识信息包含一个非直连链路站点的站点标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述非直连链路站点与所述接入点通信时的数据传输速率，所述资源分配记录中所述信道资源信息用于指示所述非直连链路站点与所述接入点建立通信所需的信道资源。
当一条资源分配记录中的所述链路类型识别信息取第二范围值时，所述资源分配记录中所述链路标识信息包含一个直连链路的链路标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述资源分配记录是直连链路站点进行直连通信的资源分配记录，所述资源分配记录中所述信道资源信息用于指示所述直连链路站点进行直连通信所需的信道资源。
所述第二范围值可以是一个值。
步骤202、处理所述资源分配信息。
需要说明的是，接收到所述资源分配信息后，在所述资源分配信息中查找链路类型识别信息取第一范围值且所述链路标识信息取 值为所述直连链路站点的站点标识的资源分配记录，若找到链路类型识别信息取第一范围值且所述链路标识信息取值为所述直连链路站点的站点标识的资源分配记录，使用所述资源分配记录中的所述信道资源信息与接入点进行非直连通信。以及，接收到所述资源分配信息后，在所述资源分配信息中查找链路类型识别信息取第二范围值且所述链路标识信息取值为所述直连链路站点所在直连链路的链路标识的资源分配记录，若找到链路类型识别信息取第二范围值且所述链路标识信息取值为所述直连链路站点所在直连链路的链路标识的资源分配记录，使用所述资源分配记录中的所述信道资源信息与所述直连链路的直连链路标识指示的直连链路对端站点进行直连通信。
这样一来，所述直连链路的资源分配记录在格式上复用所述非直连链路的资源分配记录格式，通过资源分配记录中的链路类型识别信息取第一范围值或第二范围值来指示资源分配记录是直连链路资源分配记录还是非直连链路资源分配记录，同时还将链路类型识别信息的第一范围值用于指示非直连通信所必需的传输速率信息，避免额外增加一个字段作为链路类型的识别信息，有效地降低了资源分配信息的长度，提高了带宽的使用率。
特别的，本发明不关注站点在接收到资源分配信息后，既查找直连链路资源分配记录又查找非直连链路资源分配记录两种链路类型的资源分配记录，还是只查找直连链路资源分配记录和非直连链路资源分配记录中一种链路类型的资源分配记录。例如站点预先知道该站点本次被调度的是直连通信还是非直连通信就可以只查找一种链路类型的资源分配记录。站点若找不到与该站点相关的资源分配记录，说明本次所接收的资源分配信息不涉及本站点所在的直连链路与非直连链路。
本发明实施例提供一种数据处理方法，假设应用于如图1所示的WiFi场景，所述WiFi场景中的站点与接入点运用OFDMA技术，如图5所示，包括：
步骤301、接入点生成资源分配信息。
为同时发起基于OFDMA的非直连通信及直连通信，接入点生成资源分配信息。所述资源分配信息用于指示直连链路进行直连通信或非直连链路进行非直连通信所需的物理层资源，可以包括直连链路资源分配记录和非直连链路资源分配记录。
非直连链路指接入点与站点之间的通信链路。基于OFDMA的非直连链路是指采用OFDMA机制接入点同时与多个站点进行数据传输的通信链路。
非直连链路资源分配记录用于指示所述接入点为非直连链路站点与所述接入点之间的非直连链路进行非直连通信所分配的资源。所述非直连链路资源分配记录包括链路标识信息、数据传输速率信息和信道资源信息等。
其中，所述链路标识信息包含一个非直连链路站点的站点标识。所述数据传输速率信息用于指示所述非直连链路站点与接入点之间通信所采用的数据传输速率。所述信道资源信息用于指示所述非直连链路站点与所述接入点通信所需的信道资源。
需要说明的是，由于***所支持的非直连链路的数据传输速率的数量通常小于所述非直连链路资源分配记录中所述数据传输速率信息取值空间的大小，因此在所述数据传输速率信息的取值空间中存在第一范围值与第二范围值。所述第一范围值指所述数据传输速率信息中用于指示数据传输速率的取值空间，所述第二范围值可以是所述数据传输速率信息的取值空间中除所述第一范围值外的剩余取值空间，也可以是所述剩余取值空间的子空间，也可以是所述剩余取值空间中的一个值。例如，IEEE802.11ac中数据传输速率信息字段为4比特可指示16种数据传输速率，其取值空间为0～15，但实际***仅支持10种数据传输速率，因此在IEEE802.11ac中数据传输速率信息字段仅使用0～9的取值空间用于指示数据传输速率，即为所述第一范围值，那么所述第二范围值可以是10～15组成的取值空间，也可以是10～15组成的取值空间的子空间，也可以是10～15 中的任一取值。
直连链路资源分配记录用于指示接入点为直连链路站点之间进行直连通信所分配的资源。所述直连链路资源分配记录包括链路标识信息、链路类型识别信息和信道资源信息。该直连链路资源分配记录在格式上复用所述非直连链路资源分配记录。所述直连链路指站点与站点之间直接通信的链路。
其中，所述链路标识信息包含用于标识一个直连链路的直连链路标识。实际上，所述直连链路标识信息字段复用非直连链路资源分配记录格式中链路标识信息字段，统一称为链路标识信息字段。对于所述直连链路标识，可以使用所述直连链路中的一个站点的站点标识作为所述直连链路的标识，也可以在与站点标识并行的取值空间中由接入点另行分配，具体的直连链路标识信息如何取值本发明不关注。只是单独从链路标识的取值来看，将无法区分相关的资源分配记录是分配给一个直连链路还是非直连链路，因此所述直连链路资源分配记录需要加入所述链路类型识别信息。
所述链路类型识别信息用于识别该资源分配记录是所述直连链路资源分配记录还是所述非直连链路资源分配记录。例如，所述链路类型识别信息复用所述非直连链路资源分配记录中所述数据传输速率信息字段，所述数据传输速率信息字段的第二范围值用于指示所述资源分配记录是直连链路站点进行直连通信的资源分配记录。
由于直连链路资源分配记录可复用非直连链路资源分配信息的格式，因此，资源分配记录具有统一格式，至少包括链路标识信息字段21和数据传输速率/链路类型识别信息字段22，如图6所示。其中，通过所述数据传输速率/链路类型识别信息字段识别该资源分配记录是直连链路资源分配记录还是非直连链路资源分配记录。若数据传输速率/链路类型识别信息的取值处于所述第二范围值，则判定对应的所述资源分配信息是所述直连链路资源分配记录；若数据传输速率/链路类型识别信息的取值处于所述第一范围值，则判定对应的所述资源分配信息是所述非直连链路资源分配记录，且数据传 输速率/链路类型识别信息仍用于指示非直连链路的数据传输速率。
步骤302、接入点向站点发送所述资源分配信息。
使得所述资源分配信息所述涉及的站点根据所述资源分配记录进行直连通信或非直连通信。
步骤303、直连链路站点在所述资源分配信息中查找链路类型识别信息取第一范围值且所述链路标识信息取值为所述直连链路站点的站点标识的资源分配记录。
所述直连链路站点是指已经建立直连链路的站点，该直连链路站点也可以同时与接入点建立非直连链路。
若查找到链路类型识别信息取第一范围值且所述链路标识信息取值为所述直连链路站点的站点标识的资源分配记录，执行步骤304。
若没有查找到链路类型识别信息取第一范围值且所述链路标识信息取值为所述直连链路站点的站点标识的资源分配记录，执行步骤305。
步骤304、所述直连链路站点使用步骤303所找到的资源分配记录中的所述信道资源信息与接入点进行非直连通信。
步骤305、所述直连链路站点在所述资源分配信息中查找链路类型识别信息取第二范围值且所述链路标识信息取值为所述直连链路站点所在的直连链路的直连链路标识的资源分配记录。
若查找到链路类型识别信息取第二范围值且所述链路标识信息取值为所述直连链路站点所在的直连链路的直连链路标识的资源分配记录，执行步骤306。
若没有查找到链路类型识别信息取第二范围值且所述链路标识信息取值为所述直连链路站点所在的直连链路的直连链路标识的资源分配记录，执行步骤307。
步骤306、所述直连链路站点使用步骤305所找到的资源分配记录中的所述信道资源信息与所述直连链路标识指示的直连链路对端进行直连通信。
步骤307、所述直连链路站点判定所述资源分配信息不涉及该直连链路站点所在的直连链路与非直连链路。
本发明实施例所述的数据处理方法，首先，通过资源分配记录中的数据传输速率/链路类型识别信息字段取第一范围值或第二范围值来指示资源分配记录是直连链路资源分配记录还是非直连链路资源分配记录，即直连链路资源分配记录在格式上复用非直连链路资源分配记录格式，将非直连链路资源分配记录中必须包含的传输速率信息字段复用为链路类型识别信息字段，将传输速率信息字段中未使用的取值空间作为链路类型识别信息字段的取值空间，用于指示资源分配记录为直连链路资源分配记录，从而避免额外增加一个字段作为链路类型识别信息，有效地降低了资源分配信息的长度，提高了带宽的使用率。
具体的，检查所述资源分配信息中是否包括链路标识信息字段的取值为所述站点标识或直连链路标识的资源分配记录；若所述资源分配信息中包括链路标识信息字段的取值为所述站点标识或直连链路标识的资源分配记录，检查所述资源分配记录中所述链路类型识别信息的取值范围；若所述资源分配信息中不包括链路标识信息字段的取值为所述站点标识或直连链路标识的资源分配记录，判定所述资源分配信息不涉及与所述站点所在的直连链路与非直连链路。
当所述资源分配信息中包括链路标识信息字段的取值为所述站点标识的资源分配记录时，若所述资源分配记录中所述链路类型识别信息的取值属于第一范围值，使用所述资源分配记录中的信道资源信息与接入点进行非直连通信；若所述资源分配记录中所述链路类型识别信息的取值属于第二范围值，使用所述资源分配记录中的信道资源信息与所述站点指示的进行直连通信的站点进行直连通信。
当所述资源分配信息中包括链路标识信息字段的取值为直连链路标识的资源分配记录时，所述资源分配记录中所述链路类型识别 信息的取值属于第二范围值，使用所述资源分配记录中的信道资源信息与所述直连链路标识指示的直连链路对端进行直连通信。
需要说明的是，在生成资源分配信息之前，向所述直连链路站点发送直连链路标识消息，所述直连链路标识消息包括直连链路标识，所述直连链路标识用于标识所述直连链路站点所在的直连链路。

其中，当一条资源分配记录中的所述链路类型识别信息取第一范围值时，所述资源分配记录中所述链路标识信息包含一个非直连链路站点的站点标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述非直连链路站点与所述接入点通信时的数据传输速率，所述资源分配记录中所述信道资源信息用于指示所述非直连链路站点与所述接入点通信所需的信道资源，
当一条资源分配记录中的所述链路类型识别信息取第二范围值时，所述资源分配记录中所述链路标识信息包含一个直连链路标识，所述资源分配记录中所述链路类型识别信息的取值用于指示所述资源分配记录是直连链路站点进行直连通信的资源分配记录，所述资源分配记录中所述信道资源信息用于指示所述直连链路站点进行直连通信所需的信道资源；
发送单元402，用于向站点发送所述资源分配信息，以便于所述非直连链路站点的站点标识指示的站点进行非直连通信或所述直连链路标识指示的站点进行直连通信。

可选的，所述发送单元402还用于在所述生成单元401生成资源分配信息之前，向所述直连链路站点发送直连链路标识消息，所述直连链路标识消息包括直连链路标识，所述直连链路标识用于标识所述直连链路站点所在的直连链路。
