具体实施方式
下面将结合附图，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的一部分实施例，而不是全部的实施例。可以理解，在不会产生歧义或矛盾的前提下，本领域普通技术人员通过将实施例中或实施例之间的技术特征结合而获得的其它实施例，也属于本发明保护的范围。
本发明实施例所提出的技术方案是基于如图1所示的通信系统100。该通信系统100可以支持上行竞争的传输模式。该通信系统100包括至少一个基站(base station，BS)和至少两个终端设备。在上行竞争传输模式下，基站采用准静态的 方式为终端设备分配上行资源池。该上行资源池由若干上行资源组成，多个终端设备共享该上行资源池中的资源。对于任一终端设备，当其有上行数据传输需求时，可以从上行资源池中选择一份可用的上行资源，并采用该份上行资源将数据传输给基站。基站在接收到终端设备发送的上行数据后，根据终端设备传输数据所使用的上行资源位置，确定向终端设备发送反馈信息所使用的下行资源位置，从而利用确定的下行资源将反馈信息发送给终端设备。基站利用该反馈信息通知终端设备是否已经将发送的数据正确接收。所述反馈信息可以例如包括肯定应答信息(ACKnowledgement，ACK)，或否定应答信息(Negative ACKnowledgement，NACK)。
在如图1所示的通信系统100中，例如包含采用上行竞争传输模式的两个终端设备，分别为终端设备20和终端设备21。基站10根据终端设备20、21传输数据所使用的上行资源位置，确定为终端设备20、21的反馈信息分配的下行资源位置。当终端设备20、21同时采用相同的上行资源进行数据传输，即冲突传输时，基站10能够对终端设备20、21发送的互相干扰的上行数据正确解码，并采用相同的下行资源向终端设备20、21发送反馈信息。
应理解，本发明实施例中，所述通信系统100可以为全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)，及其他应用正交频分(OFDM)技术的无线通信系统等。此外，所述通信系统100还可以适用于面向未来的通信技术，只要采用新通信技术的通信系统支持上行竞争传输，都适用于本发明实施例提供的技术方案。本发明实施例描述的系统架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
还应理解，在本发明实施例中，终端设备也可称之为用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
在本发明实施例中，基站10可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或e-NodeB)。本发明实施例对基站和终端设备不作具体限定。
需要说明的是，图1所示的通信系统100中所包含终端设备的数量仅仅是一种例举，本发明实施例也并不限制于此。例如，还可以包括更多与基站进行通信的终端设备，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统100中，尽管示出了基站10和终端设备20、21，但所述通信系统100可以并不限于包括所述基站和终端设备，例如还可以包括核心网设备或用于承载虚拟化网络功能的设备等，这些对于本领域普通技术人员而言是显而易见的，在此不一一详述。
在冲突传输情况下，例如，当两个终端设备的上行数据都被正确解码或都未被正确解码时，基站可以使用相同的下行资源发送反馈信息。但是当一个终端设备的数据被正确解码而另一个终端设备的数据未被正确解码时，基站需要使用相同的下行资源向两个终端设备发送不同的反馈信息，例如ACK和NACK。但无论基站在相同的下行资源上反馈ACK或NACK，都将造成一个终端设备接收错误的应答信息，从而导致逻辑错误。
在本发明实施例的方案中，基站接收终端设备发送的上行数据并进行解码，所述基站根据对所述上行数据的解码情况，发送所述上行数据的反馈信息，所述反馈信息携带标识的信息，所述标识包含所述终端设备的身份标识或所述上行数据的标识。从而，根据本发明实施例提供的方法，当多个终端设备存在冲突传输时，各终端设备可以根据标识的信息获得正确的反馈信息，有效避免了冲突传输所导致的信息反馈中的逻辑错误。
需要说明的是，在本发明实施例中，基站和终端设备之间发送数据所使用的上行资源和下行资源，均为时频资源。
图2示出了本发明一个实施例提供的通信方法的示意图。下面结合图2，对本实施例提供的方法进行详细说明。
S201，终端设备向基站发送上行数据。
所述终端设备利用在上行资源池中所选择的上行资源向所述基站发送所述上行数据。
可选的，当终端设备为多个时，多个所述终端设备可以采用不同的上行资源向所述基站发送上行数据，也可以采用相同的上行资源向所述基站发送上行数据。
S202，所述基站接收所述终端设备发送的上行数据，并对所述上行数据进行解码。
所述基站在接收到所述终端设备发送的所述上行数据后，将对所述上行数据进行解码，从而获取所述上行数据携带的信息。
S203，所述基站发送所述上行数据的反馈信息。
其中，所述反馈信息用于指示所述上行数据的解码情况，且所述反馈信息携带标识的信息，所述标识包含所述终端设备的身份标识或所述上行数据的标识。
所述基站可以识别发送所述上行数据的终端设备的身份标识，并将所述终端设备的身份标识的信息携带在所述反馈信息中，从而所述终端设备可以通过所述 终端设备的身份标识的信息确定所述反馈信息，避免冲突传输导致的接收反馈信息的逻辑错误。
所述基站也可以识别所述上行数据的标识，并将所述上行数据的标识的信息携带在所述反馈信息中，从而所述终端设备通过识别所述上行数据的标识信息，同样可以获得正确的反馈信息。
在本实施例中，所述基站在接收到所述终端设备发送的所述上行数据后，根据对所述上行数据的解码情况，确定需要发送的反馈信息，并为所述反馈信息分配下行资源。
可选的，当所述基站接收到至少一个所述终端设备发送的上行数据时，所述基站为所述终端设备的所述上行数据的反馈信息分配下行资源；当所述基站未接收到所述终端设备的上行数据时，基站无上行数据反馈信息的传输需求，则不分配下行资源。
所述基站还可以根据对所述上行数据的解码情况，确定发送所述上行数据的反馈信息的下行资源。具体为，当所述基站正确解码至少一个所述上行数据时，所述基站为所述上行数据的反馈信息分配下行资源；当所述基站对所有接收到的上行数据都未能正确解码时，基站不为所述上行数据的反馈信息分配下行资源。
可选的，当多个所述终端设备采用相同的上行资源向所述基站发送上行数据时，所述基站为所述上行数据的反馈信息分配相同的下行资源。
所述标识的信息可以直接地携带在所述反馈信息中，也可以间接地携带在所述反馈信息中。下面将对可能的不同实现方式做具体说明。
在一种可能的实现方式中，所述基站将所述标识的信息直接地携带在所述反馈信息中。即，所述反馈信息包含所述终端设备的身份标识或所述上行数据的标识。
其中，所述终端设备的身份标识可以是现有系统中的已有字段，例如，国际移动用户标志(International Mobile Subscriber Identity，IMSI)，该标志可以在全球范围内标识一个移动终端设备。所述终端设备的身份标识也可以是新定义的字段，用于唯一标识所述终端设备。
所述上行数据的标识可以是现有系统中的已有的标识，例如，上行解调参考信号(Demodulation Reference Signal，DM-RS)的循环移位标识。所述上行数据的标识也可以是新定义的标识，用于标识所述上行数据。
可选的，所述反馈信息还包含应答信息。所述应答信息可以是具有至少一个比特位的字段。例如，当应答信息为一个比特位的字段时，可以用“0”标识肯定应答信息ACK，“1”标识否定应答信息NACK。
所述基站可以采用显式的方式发送所述反馈信息。例如，当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息ACK和所述终端设备的身份标识，或者包含所述肯定应答信息ACK和所述上行数据的标识；当基站接收到但未能正确解码所述上行数据时，所述反馈信息包含否定应答信息NACK和所述终端设备的身份标识，或者包含所述否定应答信息NACK和所述 上行数据的标识。如此，所述基站通过通过在反馈信息中包含所述终端设备的身份标识或所述上行数据的标识，可以使所述终端设备识别出与自己发送的上行数据相对应的应答信息，避免了由于冲突传输所导致的信息反馈中的逻辑错误。
所述基站也可以采用半显式的方式发送所述反馈信息。当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息ACK和所述终端设备的身份标识，或者所述反馈信息包含肯定应答信息ACK和所述上行数据的标识；当所述基站接收到但未能正确解码所述上行数据时，所述反馈信息仅包含所述终端设备的身份标识或所述上行数据的标识。如此，不但可以避免由于冲突传输所导致的信息反馈中的逻辑错误，还节省了系统传输资源。
所述基站可以将所述反馈信息的编码信息块在下行控制信道或下行数据信道上传输。例如，所述反馈信息可以在物理下行共享信道(Physical downlink shared channel，PDSCH)上传输。
可选的，所述基站将所述终端设备的身份标识和所述应答信息(肯定应答信息或否定应答信息)，或所述上行数据的标识和所述应答信息联合编码。例如图3A所示，将终端设备20的身份标识和应答信息编码为一个信息块，将终端设备21的身份标识和应答信息编码为另一个信息块，在一个下行传输资源块上传输；或者将终端设备20发送的上行数据的标识和应答信息编码为一个信息块，将终端设备21发送的上行数据的标识和应答信息编码为另一个信息块，在一个下行传输资源块上传输。
可选的，所述基站将所述终端设备的身份标识和所述应答信息，或所述上行数据的标识和所述应答信息分别编码。例如图3B所示，将终端设备20的身份标识或上行数据的标识，与应答信息编码为不同的信息块；将终端设备21的身份标识或上行数据的标识，与应答信息编码也编码为不同的信息块，在一个下行传输资源块上传输。在图3B所示的编码方式下，基站可以采用相同的调制方法对所述终端设备的身份标识或上行数据的标识的编码后比特和应答信息的编码后比特进行调制，也可以采用不同的调制方法对所述终端设备的身份标识或上行数据的标识的编码后比特和应答信息的编码后比特进行调制。
可选的，针对不同终端设备的反馈信息，基站对它们进行联合编码。例如图4A所示，将终端设备20和终端设备21的反馈信息编码为一个信息块进行传输。
可选的，所述基站分别对每个终端设备的反馈信息进行编码。例如图4B所示，将终端设备20和终端设备21的反馈信息编码为不同的信息块进行传输。
在另一种可能的实现方式中，所述基站将所述标识的信息间接地携带在所述反馈信息中。
所述基站可以采用显式的方式发送所述反馈信息。当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息。所述基站先将所述肯定应答信息进行编码，之后采用所述终端设备的身份标识或上行信号的标识作为扰码，对编码后的所述肯定应答信息进行加扰；当所述基站接收到但未正确解码所述上行数据时，所述反馈信息包含否定应答信息。所述基站先将所述否定应答信 息进行编码，之后采用所述终端设备的身份标识或上行信号的标识作为扰码，对编码后的所述否定应答信息进行加扰。
可选的，当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息。所述基站先将所述肯定应答信息进行编码，然后根据所述终端设备的身份标识或上行数据的标识按照预定义的规则确定传输所述肯定应答信息的资源位置，并在确定的所述资源位置传输编码后的所述肯定应答信息。当所述基站接收到但未正确解码所述上行数据时，所述反馈信息包含否定应答信息。所述基站先将所述否定应答信息进行编码，然后根据所述终端设备的身份标识或上行数据的标识按照预定义的规则确定传输所述否定应答信息的资源位置，并在确定的所述资源位置传输编码后的所述否定应答信息。
所述基站也可以采用半显式的方式发送所述反馈信息。当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息。所述基站先将所述肯定应答信息进行编码，之后采用所述终端设备的身份标识或上行信号的标识作为扰码，对编码后的所述肯定应答信息进行加扰。当所述基站接收到但未正确解码所述上行数据时，不发送所述反馈信息。
可选的，当所述基站接收到并正确解码所述上行数据时，所述反馈信息包含肯定应答信息。所述基站先将所述肯定应答信息进行编码，然后根据所述终端设备的身份标识或上行数据的标识按照预定义的规则确定传输所述肯定应答信息的资源位置，并在确定的所述资源位置传输编码后的所述肯定应答信息。当所述基站接收到但未正确解码所述上行数据时，不发送所述反馈信息。
本实现方式中，通过在所述反馈信息中间接的携带标识的信息，可以在保证所述反馈信息被正确接收的情况下，减少了传输所述反馈信息占用的系统资源，从而有效减少了资源的消耗。
可选的，在本实施例的步骤S203之前，还包括步骤S2031，所述基站发送所述反馈信息的指示信息。
相应的，所述终端设备接收所述反馈信息的指示信息。
在S2031中，所述基站将所述反馈信息的指示信息发送给小区内所有处于竞争传输模式的终端设备，以便所述终端设备能够根据预先发送的所述反馈信息的指示信息接收所述反馈信息。所述基站可以通过广播信令、或无线资源控制(Radio Resource Control，RRC)信令、或媒体接入控制(Media Access Control，MAC)层信令、或物理层信令将所述指示信息通知给所述终端设备。基站向终端设备的通知方式可以是半静态的，也可以是动态的。
可选的，所述反馈信息的指示信息携带在下行控制信息(Downlink Control Information，DCI)中从基站发送至所述终端设备，DCI可以在物理下行控制信道(Physical Downlink Control Channel，PDCCH)上传输。所述反馈信息的指示信息也可以通过广播信令，或RRC信令，或MAC层信令，或其他物理层信令由基站发送给所述终端设备。
所述反馈信息的指示信息可以包括反馈信息的编码和调制方式的指示信息， 还可以包括基站为所述反馈信息所分配的下行资源的指示信息。
可选的，为了使所述终端设备能够识别DCI是否携带了反馈信息的指示信息，基站可以采用一个特定的标识对PDCCH的循环冗余码校验(Cyclical Redundancy Check，CRC)进行加扰。该标识可以是新定义一个用于指示终端设备上行数据反馈信息的无线网络临时标识，也可以是现有LTE系统中已有的标识。基站预先通过广播信令、或RRC信令、或MAC层信令、或物理层信令，将该标识或者标识的指示信息通知给小区内所有处于竞争传输模式的终端设备。
相应的，所述终端设备根据所述基站预先发送的所述指示信息的配置信息，接收PDCCH，当所述终端设备已向所述基站发送上行数据且并未接收到基站的反馈信息时，所述终端设备判别所接收的PDCCH是否携带所述反馈信息的指示信息。例如，所述终端设备可以根据PDCCH的所述CRC扰码信息进行判别。当所述终端设备判别PDCCH的CRC扰码信息指明该PDCCH携带所述反馈信息的指示信息时，所述终端设备对该PDCCH进行解码，获取相应的DCI；当所述终端设备未向所述基站发送上行数据时，所述终端设备不进行上述判别操作。
S204，所述终端设备接收所述上行数据的反馈信息。
其中，所述反馈信息携带标识的信息，所述标识包含所述终端设备的身份标识或所述上行数据的标识。
可选的，所述终端设备可以根据获取到的所述反馈信息的指示信息，确定发送所述反馈信息的下行资源位置，以及所述反馈信息的编码和调制方式。之后，所述终端设备在该下行资源位置上接收所述反馈信息，并根据所述编码和调制方式对所述反馈信息进行解调解码。
S205，所述终端设备根据所述反馈信息确定所述基站对所述上行数据的解码情况。
可选的，当所述终端设备成功获取标识的信息时，则继续获取上行数据的应答信息；若所述终端设备未能获取到标识的信息，则不进行后续应答信息的获取。
在一种可能的实现方式中，与步骤S203相对应，所述反馈信息中直接携带所述标识的信息。即，所述反馈信息包含所述终端设备的身份标识或所述上行数据的标识。
可选的，所述反馈信息还包含应答信息。
所述终端设备可以通过显式的反馈信息确定所述基站对所述上行数据的解码情况。例如，当所述反馈信息包含肯定应答信息ACK和所述终端设备的身份标识，或者包含所述肯定应答信息ACK和所述上行数据的标识时，所述终端设备确定所述基站接收到并正确解码所述上行数据；当所述反馈信息包含否定应答信息NACK和所述终端设备的身份标识，或者包含所述否定应答信息NACK和所述上行数据的标识时，所述终端设备确定所述基站接收到但未能正确解码所述上行数据。
所述终端设备也可以通过半显式的反馈信息确定所述基站对所述上行数据的解码情况。例如，当所述反馈信息包含肯定应答信息ACK和所述终端设备的 身份标识，或者包含所述肯定应答信息ACK和所述上行数据的标识时，所述终端设备确定所述基站接收到并正确解码所述上行数据；当所述反馈信息仅包含所述终端设备的身份标识或所述上行数据的标识时，所述终端设备确定所述基站接收到但未能正确解码所述上行数据。
在另一种可能的实现方式中，与步骤S203相对应，所述反馈信息中间接地携带所述标识的信息。
可选的，所述反馈信息包含肯定或否定应答信息。所述终端设备可以利用所述终端设备的身份标识或所述上行数据的标识解扰所述反馈信息，获得与发送的所述上行数据相关联的应答信息。
可选的，所述终端设备可以根据所述终端设备的身份标识或上行数据的标识按照预定义的规则确定接收所述应答信息的资源位置，并在确定的所述资源位置接收所述应答信息。
通过本实施例提供的通信方法，可以使终端设备接收正确的上行数据的反馈信息，有效避免冲突传输所导致的信息反馈中的逻辑错误。
