Description

资源指示方法、装置和设备 技术领域
本发明实施例涉及通信技术，特别涉及一种资源指示方法、装置和设备。
背景技术
随着802.11ac标准中下行MU-MIMO(Multi-User Multiple Input Multiple Output；简称：多用户多输入多输出)的引入，一个接入点(Access Point；简称：AP)可以利用不同的时空流同时向多个站点(Station；简称：STA)发送互相独立的数据。多用户传输会提高系统效率，但同时也需要为每个站点来提供各种参数及所占据资源的位置的指示。
现有技术中，通常按照逐个站点或者站点组进行资源的指示。表一为现有技术中单个站点的资源指示结构示意图，表二为现有技术中MU-MIMO站点组的资源指示结构示意图。
表一
Figure PCTCN2015078140-appb-000001
表二
Figure PCTCN2015078140-appb-000002
其中，对于站点的资源指示，如表一所示，部分关联标识(Partial Associate ID；简称：PAID)用于标识接收端，并承载关联标识的部分信息，下行/上行类型(Downlink/Uplink type；简称：DL/UL type)用于指示资源块属于下行帧还是上行帧，调制与编码策略(Modulation and Coding Scheme；简称：MCS)用于指示调制与编码策略，时空流数(Number of Space-Time Stream；简称：NSTS)用于指示使用的时空流个数，资源单元分配(Resource Unit Allocation，简称：RU alloc)和时间分配(Time allocation，简称：Time alloc)分别在频率上和时间上指示占据的资源块的位置指引，低密度奇偶校验码 (Low Density Parity Check；简称LDPC)用于指示是否使用LDPC编码方式；空时分组编码(Space Time Block Coding；简称：STBC)为用来指示是否采用STBC，循环冗余码(Cyclic Redundancy Code；简称：CRC)用来保存CRC校验比特；尾部比特(Tail)用来存放二进制循环卷积码(Binary Convolution Code；简称：BCC)的6个比特的尾部。对于MU-MIMO站点组的资源指示，如表二所示，组标识(Group ID；简称：GID)用来指示MU-MIMO站点组的标识；此外，对于站点组内的每个站点，要分别指示其MCS以及NSTS等参数。
另外，还可以采用按照逐个资源块进行资源指示的方式，其中包括站点或者站点组字段，用于指示该资源块是用于传输站点的数据还是用于传输站点组的数据；资源块的大小、站点标识(Stations ID；简称：STA ID)/GID用来指示单个站点或者站点组的标识。
然而，现有技术中，对单个站点进行资源指示时，需要占用60bit的空间，对站点组进行资源指示时，则需要占用84bit的空间，这样会使得信令开销较大，造成系统资源的浪费。

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做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。
图1为本发明提供的资源指示方法的系统结构示意图，如图1所示，在 该系统结构中，STA 12通常指的是各种终端设备，例如可以是pad、上网本、手机等。AP 11将各个STA 12连接到一起，AP11通过向STA12发送包含资源指示信息的数据帧，使STA12根据该资源指示信息确定传输数据的目的站点，所传输数据的位置及传输参数，以进行数据的传输。通常，一台AP下面要接入多台STA，因此，在AP同时对多台STA进行资源指示时，如何降低信令的开销，减少系统资源的浪费，是一个非常重要的问题。
图2为本发明一实施例的资源指示方法的流程示意图，本实施例的执行主体可以是AP，也可以是具有AP功能的其他设备。在上述图1所示系统结构的基础上，如图2所示，本实施例的方法可以包括：
步骤201、接入点AP生成资源指示信息，所述资源指示信息用于指示被调度的站点或者站点组，以及，所述被调度的站点或者站点组需要使用的通信资源，所述资源指示信息中包含资源指示方式字段；所述资源指示方式字段包含：针对所述被调度的站点或者站点组的每一个，明示的指示所述需要使用的通信资源，或者，缺省的指示所述需要使用的通信资源。
在本实施例中，明示的指示需要使用的通信资源是指AP将完整的指示出被调度的站点或者站点组需要使用的通信资源；而缺省的指示需要使用的通信资源是指AP不需要完整的指示出被调度的站点或者站点组需要使用的通信资源，被调度的站点或者站点组可以根据上一帧中其所使用的通信资源，确定传输本帧数据需要使用的通信资源，或者根据传输本帧数据时其所使用的通信资源，确定传输下一帧数据时需要使用的通信资源。当STA或者站点组在传输本帧数据时采用与在上一帧中采用完全相同或者部分相同的通信资源，或者在传输下一帧数据时采用与在本帧中采用完全相同或者部分相同的通信资源时，可以采用缺省的方式进行通信资源的指示，反之，则采用明示的方式进行通信资源的指示。其中，通信资源包括站点标识信息、资源位置信息和资源参数信息。
步骤202、发送所述资源指示信息，以便于所述被调度的站点或者站点组根据所述资源指示信息通过所述指示的通信资源进行通信。
具体的，可以有多种具体的资源指示方式字段，下面详细说明之：
实施例一
在本实施例中，参考图3a、3b，图3a为资源指示信息的结构示意图一，图3b为资源指示信息的结构示意图二，AP在信令字段(Signal Field；简称SIG)B或者trigger frame中，可以采用1比特的第一指示，第一指示例如可以为压缩模式指示字段，其用来指示本次调度中是否需要明示的指示所述被调度的站点或者站点组需要使用的通信资源，也就是说，用于指示本次调度中进行资源指示时，是否需要指示完整的通信资源，例如针对每一个被调度的STA或者站点组，是否均需要指示出站点标识信息、资源位置信息和资源参数信息。例如：将第一指示置0，则针对每一个被调度的STA或者站点组，均需要指示出完整的通信资源，若将第一指示置1，则采用不完整的通信资源进行资源指示，例如可以指示出通信资源中的站点标识信息、资源位置信息和资源参数信息中的至少一个。当然，也可以在第一指示为1时，指示完整的通信资源，第一指示为0时，采用不完整的通信资源进行资源指示，本发明对此不作特别限制。
其中，站点标识信息用于标识STA或站点组；资源位置信息用于指示在频率上和/或在时间上占据的资源块的指引，例如：用于指示以下参数中的至少一个：资源块的起始位置、资源块的大小、MU MIMO传输时所占据时空流的指引等；资源参数信息包括以下之一或其任意组合：数据传输的调制与编码策略MCS、低密度奇偶校验码LDPC、空时分组编码STBC等。
参考图3a、3b，资源指示方式字段可以为第二指示和/或第三指示；第二指示用于指示所有被调度的STA或者站点组在传输本帧数据时是否均采用与在上一帧中采用完全相同或者部分相同的通信资源，或者第三指示用于指示所有被调度的STA或者站点组在传输下一帧数据时是否均采用与在本帧中采用完全相同或者部分相同的通信资源。
具体地，在传输本帧数据时采用与在上一帧中采用完全相同或者部分相同的通信资源的STA或站点组的类型包括以下三种：(1)传输本帧数据时所使用资源的资源位置信息与传输上一帧数据时所使用资源的资源位置信息相同的STA或者站点组；(2)传输本帧数据时所使用资源的资源参数信息与传输上一帧数据时所使用资源的资源参数信息相同的STA或站点组；(3)传输本帧数据时所使用资源的资源位置信息和资源参数信息均与传输上一帧数据时所使用资源的资源位置信息和资源参数信息相同的STA或者站点组。
需要进行说明的是，对于第一种类型，在对STA或者站点组进行资源指示时只需要指示资源参数信息即可，对于第二种类型，在对STA或者站点组进行资源指示时只需要指示资源位置信息即可，而对于第三种类型，则不需要对STA或者站点组进行资源指示。
在资源指示信息中设置第二指示，以指示传输本帧数据时所有被调度的STA或者站点组在传输本帧数据时是否均采用与在上一帧中所采用的完全相同或者部分相同的通信资源，或者第三指示用于指示所有被调度的STA或者站点组在传输下一帧数据时是否均采用与在本帧中所采用的完全相同或者部分相同的通信资源。需要进行说明的是，若所有STA或者站点组在传输本帧数据时采用的通信资源均与传输上一帧数据时采用的通信资源完全相同时，则不对站点或者站点组进行资源指示；若所有STA或者站点组在传输本帧数据时采用的通信资源与传输上一帧数据时采用的通信资源部分相同时，则根据上一帧中被缺省指示通信资源的STA或者站点组的排列顺序，进行逐个站点或者站点组的资源指示，以确定站点或者站点组在传输本帧数据所使用的通信资源。对于所有STA或者站点组在传输下一帧数据时均采用与在本帧中采用完全相同或者部分相同的通信资源时的情况，与所有STA或者站点组在传输本帧数据时均采用与在上一帧中采用完全相同或者部分相同的通信资源时类似，此处不再赘述。
举例来讲，在802.11ax中引入了上行多用户传输，可以通过触发帧向多个用户同时索取信道探测信息，然后通过多个触发帧，向同一批用户多次索取信道探测信息，因此在这种场景，所有用户均为被缺省指示通信资源的STA或者站点组，故可以通过第二指示来指示本次传输与上一次传输采用完全相同或部分相同的通信资源。例如：AP向所有STA或站点组广播空数据分组声明和空数据分组触发帧之后，各STA或站点组会同时向AP反馈多用户信道状态信息，此时，AP会将第二指示的值置为1，并向各STA或站点组发送携带有第二指示的波束成形报告轮询触发帧，各STA或站点组接收到携带有第二指示的波束成形报告轮询触发帧之后，即可获知此时所有的STA或站点组均为被缺省指示通信资源的STA或者站点组。
进一步地，对于包含资源指示信息的触发帧，可能会存在多种类型，如：索取信道探测信息的触发帧，索取节能轮询帧的触发帧，索取确认信息的触 发帧等，因此，本实施例中还可以通过将第二指示与触发帧的类型相结合来指示所有的STA或站点组是否均为被缺省指示通信资源的STA或者站点组，具体地，若STA或站点组接收到某种类型的触发帧，则可默认第二指示为1，也即指示所有的STA或站点组均为被缺省指示通信资源的STA或者站点组。例如，若STA或站点组接收到波束成型报告轮询类型的触发帧，则可默认该触发帧中携带有第二指示，而且该第二指示的值为1，即所有STA或站点组在传输本帧数据时采用与上一帧采用的完全相同或部分相同的通信资源。值得注意的是，也可以将第二指示与其他类型的触发帧相结合，对于触发帧的具体类型，本发明对此不作限制。第三指示的指示方式与第二指示类似，此处不再赘述。
需要说明的是，资源指示信息中可以同时包含上述第一指示、第二指示和第三指示，也可以只包含其中的一种。
本发明实施例提供的资源指示方法，通过在资源指示信息中设置第二指示和/或第三指示，当确定所有STA或者站点组均为被缺省指示通信资源的STA或者站点组时，可以直接通过传输上一帧或本帧数据所使用的通信资源，确定出传输本帧或下一帧数据所使用的通信资源，由此避免了现有技术中每一次进行资源指示时，资源指示信息中都需要明示的指示被调度的STA或者站点组需要使用的通信资源的现象，从而有效地降低了资源指示信息的开销，减少了系统资源的浪费。
实施例二
参考图3c，或者图5，图3c为第十指示的结构示意图一，图5为第十指示的结构示意图二，在一个可选的实施方式中，资源指示信息为物理层信令或者媒体接入控制层(Medium Access Control；简称：MAC)帧；该资源指示信息或该MAC帧包括第九指示或第十指示，第九指示例如可以为资源重用比特，第十指示例如可以为资源重用位图，该第九指示或第十指示中的每一位比特用于指示该比特相对应的STA或者站点组在传输下一帧数据时是否采用与在本帧中采用完全相同或者部分相同的通信资源。
具体地，第九指示或第十指示可以存储在资源指示信息中，也可以存储在MAC帧中，以指示STA或者站点组在传输下一帧数据时是否采用与在本 帧中采用完全相同或者部分相同的通信资源，以起到提前通知STA或者站点组的作用。在实际应用中，当第九指示或第十指示存储在资源指示信息中时，对于第九指示的指示方式，可以通过对每个STA或者站点组进行资源指示时，在资源指示信息中添加一个新的比特位，用于指示该STA或者站点组在传输下一帧数据时是否采用与在本帧中采用完全相同或者部分相同的通信资源；对于第十指示的指示方式，可以通过集中采用一个N位的第十指示来对所有的STA或者站点组中的每一个STA或者站点组进行指示，其中，N为正整数。STA或者站点组通过对第九指示或第十指示进行解析，即可提前获知自身在传输下一帧数据时是否采用与在本帧中采用完全相同或者部分相同的通信资源。例如：如图3c所示，若第十指示为1110100，则说明STA1、STA2、STA5和STA6在传输下一帧数据时采用的通信资源与本帧中所采用的通信资源不同，而站点组(Multi-User Group；简称：MUG)1、STA3和STA8在传输下一帧数据时采用与在本帧中采用完全相同或者部分相同的通信资源。当第九指示或第十指示存储在MAC帧中时，可以采用某个STA或站点组数据的MAC帧帧头中的一个比特来指示该STA或站点组在传输下一帧数据时是否为被缺省指示通信资源的STA或站点组，也可以通过在某个STA或站点组数据的MAC帧中，采用一个N位的第十指示来指示该STA或站点组在传输下一帧数据时是否采用与在本帧中采用完全相同或者部分相同的通信资源，以起到提前通知STA或站点组的作用。
参考图4，图4为资源位置信息指示示意图，在又一个可选的实施方式中，资源指示方式字段为第四指示；该第四指示用于指示以下之一或其任意组合：被明示指示通信资源的STA或站点组的数量，被缺省指示通信资源的STA或站点组的数量，被明示指示通信资源的STA或站点组以及被缺省指示通信资源的STA或站点组的数量之和。
在本实施例中，假设某个STA或站点组的资源位置信息不需要依赖于其他站点或站点组的资源位置信息，即每个STA或站点组的资源位置信息均相互独立，也就是说，对于某个STA或站点组，已明确指示出其所使用的资源块的起始位置和资源块的大小时，AP在对其进行资源位置信息的指引时，并不依赖于其他STA或站点组的资源位置信息。例如，如图4所示，对于由 STA5、STA6、STA7和STA8组成的MU-MIMO站点组，已明确指示其所使用的资源块的起始位置为5，资源块大小为4，则AP在对其进行资源位置信息的指引时，不需要依赖于其他STA或站点组的资源位置信息。在这种情况下，在每一次进行资源指示时，需要先统计被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量。需要进行说明的是，若需要对被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组进行资源指示时，则需要统计被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组的数量，若只需要对被明示指示通信资源的STA或站点组进行资源指示时，则仅统计被明示指示通信资源的STA或站点组的数量即可。
进一步地，STA或站点组根据上一帧数据中携带的第九指示或第十指示，会获知自身在传输本帧数据时为被缺省指示通信资源的STA或站点组，即在传输本帧数据时采用与在上一帧中采用完全相同或者部分相同的通信资源，则STA或站点组在得到被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量之后，会先遍历所有的被明示指示通信资源的STA或站点组接收到的资源指示信息，以获取本次新分配的通信资源。遍历完成之后，再结合上一帧的第九指示或第十指示，获得其在所有STA或站点组中的位置信息，例如：其在所有的STA或站点组中的排列顺序，以根据该排列顺序确定传输上一帧数据所使用的通信资源。具体地，AP会将STA或站点组进行排序，在实际应用中，首先排列被明示指示通信资源的STA或站点组，将被缺省指示通信资源的STA或站点组排列在被明示指示通信资源的STA或站点组的后面，而对于被缺省指示通信资源的STA或站点组的相对顺序，则按照上一帧中指示的顺序进行排列。例如，如图5所示，对于第二帧数据来说，假设MUG3、STA4、STA11为被明示指示通信资源的STA或站点组，而STA1、STA2、STA5和STA6为上一帧中指示的被缺省指示通信资源的STA，其中4个被缺省指示通信资源的STA的顺序则按照上一帧中的相对顺序进行排序，则在进行资源指示时，会先进行3个被明示指示通信资源的STA或站点组的资源指示，再进行4个被缺省指示通信资源的STA的资源指示。当被缺省指示通信资源的STA知道其在所有STA中的排列位置之后，即可获知哪一个资源指示信息是指向自己的，由此可确定出传输上一帧数据 时其所使用的通信资源。由此可见，每次STA或站点组在读取第九指示或第十指示时，都需要保存自身在所有站点或站点组中的排列位置。
如果STA或站点组获知自身为被明示指示通信资源的STA或站点组，在获取到被明示指示通信资源的STA或站点组的数量之后，会遍历所有被明示指示通信资源的STA或站点组接收到的资源指示信息，以在所有的资源指示信息中搜寻其自身的站点标识信息，以确定是否有数据传给自己，若有，则根据资源指示信息确定出传输本帧数据需要使用的通信资源。
本发明实施例提供的资源指示方法，通过第四指示获知被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量，并根据被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量以及上一帧数据中携带的第九指示或第十指示获知在传输本帧数据时STA或站点为被缺省指示通信资源的STA或站点组还是被明示指示通信资源的STA或站点组，由此可以分别指示被调度的STA或者站点组需要使用的通信资源，避免了现有技术中每一次进行资源指示时，资源指示信息中都需要包含完整的通信资源的现象，有效地降低了资源指示信息的开销，减少了系统资源的浪费。
需要进行说明的是，对于被缺省指示通信资源的STA或站点组的资源指示，除了采取现有技术中的指示，也可以采取增量指示。例如对于MCS，前后两次的信道不会发生明显的变化，即使变化了，MCS也不会变很多，因此利用2比特指示MCS的变化量即可，而不需要利用3比特进行完整的指示。也可以采取几种相对固定的模式，比如00代表信道质量更好，采取速率更好的资源参数；01代表信道质量不变，无需更改资源参数；10代表信道质量变差，采取速率更差的资源参数。对于某一个格式具体的资源参数指示，本发明方案不作具体限制。
实施例三
可替换的，参考图6，图6为第五指示的结构示意图，在又一个可选的实施方式中，资源指示方式字段为X比特的第五指示；该第五指示中的每一个比特分别用于指示所述比特对应的STA或者站点组在传输本帧数据时是否采用与在上一帧中采用完全相同或部分相同的通信资源。
在本实施例中，假设某个STA或站点组的资源位置信息不需要依赖于其他站点或站点组的资源位置信息，即每个STA或站点组的资源位置信息均相互独立。在这种情况下，在每一次进行资源指示时，需要先统计被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量。在具体的实现过程中，除利用第四指示获得被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量之外，还可以通过第四指示获得被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组的数量之和，再结合第五指示来获得被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量。例如：如图6所示，首先通过第四指示可以获知共有7个STA和站点组，而且第五指示为1101011，则说明在传输本帧数据时STA1、STA2、MUG1、STA 3和STA8为被明示指示通信资源的STA或站点组，而STA5和STA6为传输本帧数据时被缺省指示通信资源的STA，进而可以得知在传输本帧数据时被明示指示通信资源的STA或站点组的数量为5，被缺省指示通信资源的STA的数量为2。
进一步地，资源指示信息可以同时包含图5所示的第十指示，和图6所示的第五指示。这时，STA或站点组根据上一帧的第十指示，获知其自身为被缺省指示通信资源的STA或站点组时，再通过第四指示获知被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组的数量之和，然后结合本帧的第五指示，获得该STA或站点组在传输本帧数据时在所有STA或站点组中的位置信息，当被缺省指示通信资源的STA或站点组知道其在所有STA或站点组中的排列位置之后，即可获知哪一个资源指示信息是指向自己的，由此即可确定出传输上一帧数据时其所使用的通信资源。
如果STA或者站点组根据上一帧的第十指示，获知其自身为被明示指示通信资源的STA或站点组时，可以通过第四指示获知被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组的数量之和，然后结合本帧的第五指示，遍历所有被明示指示通信资源的STA或站点组接收到的资源指示信息，以在所有的资源指示信息中搜寻自身的站点标识信息，以确定是否有数据传给自己，若有，则根据资源指示信息确定出传输本帧数据所需要的通信资源。
实施例四
假设每个STA或站点组的资源位置信息需要依赖于其他STA或站点组的资源位置信息，即AP在对某一个STA或站点组进行资源位置信息的指引时，为了节省开销，只给出其所使用的资源块的大小，而不给出资源块的起始位置，此时，该STA或站点组需要对排在它前边的所有STA或站点组的资源块大小进行累加，从而得知其所在资源块位置的起始值。继续参考图4，如果只指示资源块的大小，则对于STA4来讲，其通过对STA1、STA2和STA3的资源块大小进行累加，得到资源块的起始位置0+1+2+1＝4，然后结合其本身资源块的大小信息，从而得知其在频率上的资源位置信息。对于这种情形，由于被明示指示通信资源的STA或站点组需要依赖于被缺省指示通信资源的STA或站点组的资源位置信息，因此，在进行资源指示时，需要对被缺省指示通信资源的STA或站点组的资源位置信息进行指示，这样，对于被明示指示通信资源的STA或站点组，便可以通过被缺省指示通信资源的STA或站点组的资源位置信息计算出自身所占资源块的位置信息。
参考图7，图7为对被缺省指示通信资源的STA或站点组进行资源位置信息指示的示意图，图7与图5或者图6所示实施方式不同的是，在图7所示的帧中，还包含被缺省指示通信资源的STA或站点组的资源位置信息的指示。具体地，对于被缺省指示通信资源的STA或站点组来说，其可以通过对资源位置信息的计算，判断出某个资源指示信息是否是来指示自己的。例如，若某个被缺省指示通信资源的STA或站点组在传输上一帧数据时所占用的资源块的起始位置为3，资源块的大小为4，当在传输本帧数据时，其根据资源指示信息获知某个被缺省指示通信资源的STA或站点组的资源位置信息中资源块的起始位置为3，资源块的大小为4，与其自身在传输上一帧数据时所占用的资源块的起始位置与资源块大小均相同，则该被缺省指示通信资源的STA或站点组即可得知该被缺省指示通信资源的STA或站点组为自己，由此可以判断出该资源指示信息是用来指示自己的。
另外，该被缺省指示通信资源的STA或站点组也可以通过结合第九指示或第十指示来确定资源位置信息，在实际应用中，被缺省指示通信资源的STA或站点组可以结合上一帧数据中携带的第九指示或第十指示，确定其在第十 指示中的位置，由此获知自身在传输本帧数据时是第几个被缺省指示通信资源的STA或站点组，以此确定资源位置信息。举例来说，如图7所示，在第一帧数据中，第十指示为1110100，则对于STA6来说，其得知在传输下一帧数据时一共会有4个被缺省指示通信资源的STA或站点组，而它排在最后一个。而在第二帧数据中，第五指示为1110010，STA6会知道代表它的是第四个“1”，其排在所有站点的第6个，此时，其可根据该位置得知哪个资源指示信息是用来指示自己的，以确定出传输数据所使用的资源。
需要进行说明的是，也可以采用比特的方式来实现第五指示的功能，即采用逐个比特对每个STA或站点组进行指示，以指示比特对应的STA或站点组在传输本帧数据时是否采用与在上一帧中采用完全相同或者部分相同的通信资源。
前述图3c-图7所示的资源指示方法，通过所有STA或者站点组的总数量及第五指示可获知被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量，并根据被缺省指示通信资源的STA或站点组和/或被明示指示通信资源的STA或站点组的数量以及上一帧数据中携带的第十指示或者上一帧和本帧的位置信息是否相同获知在传输本帧数据时STA或站点组的类型，由此可以分别指示STA或者站点组需要使用的通信资源，避免了现有技术中每一次进行资源指示时，资源指示信息中都需要包含完整的通信资源的现象，有效地降低了资源指示信息的开销，减少了系统资源的浪费。
实施例五
参考图3b，在又一个可选的实施方式中，资源指示方式字段为Z比特的第六指示；该第六指示用于指示被缺省指示STA区域和被明示指示STA区域的大小，例如该区域包含的最小资源块的数量。被缺省指示STA区域内的STA或站点组在传输本帧数据时均采用与在上一帧中采用完全相同或者部分相同的通信资源，被明示指示STA区域内至少有一个STA或站点组在传输本帧数据时采用与在上一帧中采用不同的通信资源；Z为正整数。
另外，资源指示方式字段为X比特的第七指示，该第七指示中每个比特 用于指示所述比特对应的STA或站点组所属区域是否为被缺省指示STA区域。
具体地，在本实施例中，假设每个STA或站点组的资源位置信息均需要依赖于其他STA或站点组的资源位置信息，对于这种情形，由于被明示指示通信资源的STA或站点组需要依赖于被缺省指示通信资源的STA或站点组的资源位置信息，因此，在进行资源指示时，不能任意省略对被缺省指示通信资源的STA或站点组的资源位置信息的指示。对于这个问题，本发明中可以采用将带宽进行划分的方式来指示被缺省指示STA区域和被明示指示STA区域，在具体的实现过程中，可以将整个带宽按照预设模式划分为若干个部分，每一个部分均为一个区域。例如：若整个带宽为80M，需要平均分配成4个部分，以形成4个区域，则每个区域为20M。另外，也可以采用其他方式进行划分，比如上述4个区域，可以再对其中某一个20M的区域按照资源单元分成9个子部分，其中，资源单元为最小资源块，则可以将该20M内每3个资源单元当作一个区域，这样总共有3+1+1+1＝6个区域。对于区域的划分方式，可以根据实际情况进行选取，而对于每个区域的大小，可以在传输每一帧数据时进行指示，也可以采取预置的规则进行设计，本发明对区域的具体的划分方式和指示方式不做限制。
将带宽进行划分之后，在进行资源指示时，采用第七指示来指示哪些区域内的所有STA或站点组均为被缺省指示通信资源的STA或站点组，哪些区域内至少有一个被明示指示通信资源的STA或站点组。举例来讲，图8为第七指示的结构示意图，如图8所示，假设整个带宽为20M，根据预设模式将带宽划分为3个区域，若以1代表某个区域内至少存在一个被明示指示通信资源的STA或站点组，以0代表某个区域内的STA或站点组均为被缺省指示通信资源的STA或站点组，因此，第一个下行帧的指示为111，则说明3个区域内均至少存在一个被明示指示通信资源的STA或站点组，而第二个下行帧的指示位100，说明第一个区域内存在至少一个被明示指示通信资源的STA或站点组，而第二个区域和第三个区域内的STA或站点组则均为被缺省指示通信资源的STA或站点组。值得注意的是，这里的1和0是相对值，也可以1代表该区域内的STA或站点组均为被缺省指示通信资源的STA或站点组，以0代表该区域内至少存在一个被明示指示通信资源的STA或站点组。值得 注意的是，此时的被缺省指示通信资源的STA或站点组为传输本帧数据时所使用资源的资源位置信息与传输上一帧数据时所使用资源的资源位置信息相同的STA或站点组。
当STA或站点组根据第七指示确定出在传输本帧数据时该STA或站点组所属区域为被缺省指示STA区域时，需要根据第四指示获知在每个区域内所包含的被缺省指示通信资源的STA或站点组的数量，由于被缺省指示STA区域内的所有STA或站点组都属于被缺省指示通信资源的STA或站点组，因此，STA根据每个区域内所包含的STA或站点组的数量以及上一帧中其所在被缺省指示STA区域内的排列顺序，即可获知该STA或站点组在传输本帧数据时自身在被缺省指示STA区域内的位置信息，由此可判断出哪一个资源指示信息是指向自己的，以确定本次新分配的通信资源，以及传输上一帧数据所使用的通信资源。
当STA或站点组在根据第七指示获知在传输本帧数据时该STA或站点组所属区域为被明示指示STA区域时，则会根据被明示指示STA区域的大小，遍历所有被明示指示STA区域接收到的资源指示信息，在资源指示信息所包含的标识信息中搜寻自身的站点标识信息，以确定是否有数据传给自己，若有，则根据资源指示信息确定传输本帧数据所需要的通信资源。
需要进行说明的是，对于某一个站点或站点组，若其使用的部分通信资源与传输上一帧数据所使用的通信资源相同，而部分通信资源是本次新分配的，此时，该STA或站点组可能既在被缺省指示STA区域内，又在被明示指示STA区域内。在这种情况下，该站点或站点组首先需要在被明示指示站点区域内读取新的资源指示信息，同时还需要在被缺省指示站点区域内结合上一帧的通信资源读取重用部分的资源指示信息。
另外，在进行资源指示时，AP针对第七指示指示为0的区域和指示为1的区域分别指示。在实际应用中，可将所有指示的被明示指示STA区域联合在一起进行资源指示，因为每个站点或站点组清楚的知道每个区域资源块位置的起始值，因此即使缺失了被缺省指示站点区域内站点的位置信息，每个STA或站点组依然可以知道自己所在的资源位置。例如，图9为对被缺省指示通信资源的STA或站点组和被明示指示通信资源的STA或站点组进行资源指示的示意图，如图9所示，对于下行帧2的资源指示，当第七指示为101 时，说明区域1和区域3为被明示指示STA区域，区域2为被缺省指示STA区域。则首先对区域1和区域3内的站点进行资源指示，这样，当整个带宽内存在被缺省指示通信资源的STA或站点组，而且在被缺省指示通信资源的STA或站点组的资源块大小等资源位置信息缺失时，即使仅指示每个站点或站点组的资源块大小，对于被明示指示通信资源的STA或站点组来说，其依然可以知道自己的资源块位置。举例来讲，对于STA9，当其对排在它前边的被明示指示通信资源的STA4、STA2、STA7所占资源块大小的累加(1+1+1＝3)后，会发现第一个区域已经排完，因此当其在第四个位置发现自己的站点标识时，会得知AP将在第三个区域继续进行资源分配，所以STA9会知道自己的起始位置为6，而不是按照连续排列时的3，而对于其后的站点或站点组，也会在6的基础上继续累加排在其前边站点的资源块大小，从而得知自己资源块的起始位置。
需要进行说明的是，也可以采用比特的方式来实现第七指示的功能，即采用逐个比特对每个STA所属的区域进行指示。
本发明实施例提供的资源指示方法，通过第六指示和第七指示区分在传输本帧数据时STA所属是否为被缺省指示STA区域，由此分别指示STA或者站点组需要使用的通信资源，避免了现有技术中每一次进行资源指示时，资源指示信息中都需要包含完整的通信资源的现象，有效地降低了资源指示信息的开销，减少了系统资源的浪费。
进一步地，在上述实施例的基础上，当AP没有接收到某个区域内的某个STA或站点组发送的确认消息或块确认消息时，即AP发现该STA或站点组错过了某一个帧时，则对于该STA或站点组所在的区域来说，即使在下一帧时将会成为被缺省指示STA区域，也要将该区域指示为被明示指示STA区域，因为AP无法保证该STA或站点组在当前帧正确接收了资源指示信息。举例来讲，图10为某个STA或站点组没有正确接收数据时在下一帧的资源指示信息中第七指示的处理规则示意图，如图10所示，对于下行帧2的STA3，在进行下行帧2的传输时，若AP没有收到STA3的确认信息，因此在进行下行帧3的传输时，即使区域2为被缺省指示STA区域，也指示区域2为被明示指示STA区域，对区域2的站点重新进行资源指示。
实施例六
在又一个可选的实施方式中，资源指示方式字段为M比特的第八指示；该第八指示用于指示本帧数据的传输序列；M为正整数。
具体地，在资源指示信息中还可以增加2比特或者3比特的第八指示，以指示本次数据帧的传输序列，以防止STA或者站点组将数据帧漏传。例如：假设第一帧数据的第八指示为00、第二帧为01、第三帧为10，第四帧为11，若某个STA或站点组在传输第一帧数据时，根据第十指示得知其在传输第二帧数据时为被缺省指示通信资源的STA或站点组，但是由于碰撞等原因，该STA或站点组根据第八指示发现其没有收到第二帧数据，而收到的是第三帧数据或第四帧数据时，会发现自己错过了第二帧数据，因此不再认定自己是被缺省指示通信资源的STA或站点组。值得注意的是，若第八指示只有2比特，则对于第五帧数据，则重新利用00进行指引。需要进行说明的是，由于上行及下行的业务普遍不同，因此可以针对上行帧和下行帧分别进行指引，当然，也可以在一起进行指引，对于第八指示的具体指引方式，本发明在此不作特别限制。
本发明实施例提供的资源指示方法，通过在资源指示信息中设置第八指示，以指示本次数据帧的传输序列，避免出现数据帧的漏传现象，提高了系统的可靠性。
