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，所描述的实施例是本发明的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：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)通信系统等。
本发明实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的网元。例如，LTE和LTE-A中无线接入网络的网元包括eNB(eNodeB，演进型基站)，WCDMA中无线接入网络的网元包括RNC(Radio Network Controller，无线网络控制器)和NodeB，类似地，WiMax(Worldwide Interoperability for Microwave Access，全球微波互联接入)等其它无线网络也可以使用与本发明实施例类似的方案，只是基站系统中的相关模块可能有所不同，本发明实施例并不限定。
还应理解，在本发明实施例中，基站，可以是GSM或CDMA中的基站(简称BTS，英文Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(简称eNB或e-NodeB，英文evolved Node B)，本发明并不限定。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(RAN，Radio Access Network)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户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。
还应理解，本文中的物理资源块是一个广义的概念，在实际应用中，可以为物理资源块(Physical Resource Block，PRB)，也可以为物理资源块对PRB-pair，下文中仅以物理资源块为PRB为例进行说明。本发明实施例并不限于此。
图1A是根据本发明一个实施例的数据传输的方法的示意流程图，图1所示的方法可以由基站执行，具体地，该方法可以包括：
130，基站向用户设备发送资源指示信息，资源指示信息用于指示基站与用户设备间的目标传输资源，目标传输资源为多个传输资源中的一个，其中多个传输资源中的最小传输资源小于一个物理资源块PRB；
具体地，基站通过资源指示信息指示用户设备与基站之间的承载业务数据的目标传输资源，换句话说基站通过资源指示信息通知用户设备基于目标传输资源上接收或发送业务数据。
小于一个PRB的最小分配资源可以是1/4PRB、1/8PRB或1/2PRB等，本发明实施例并不限于此。
140，基站基于目标传输资源与用户设备进行数据传输。
具体地，基站基于目标传输资源与用户设备可以进行上行数据的传输也可以进行下行数据的传输。
具体而言，基站调度时，会分配当前信道条件下可以传输该业务数据量的最少RB资源，由于现有TBS表格的最小资源粒度为1个PRB，因此基站至少要为用户设备分配一个PRB资源用于数据传输。现有技术在当业务的数据量少于一个PRB资源时，为了满足现有资源传输要求，经常需要在物理层的传输块中增加填充比特(padding bit)，影响网络性能，然而本发明实施例中的最小分配资源小于一个PRB，因此，本发明实施例中的资源分配中的最小分配资源可以小于一个PRB，能够减少或者避免填充比特，减少资源浪费。
在本发明实施例中，由于传输资源中的最小传输资源小于一个PRB，因此，本发明实施例能够避免最小传输资源为1个PRB的限制，减少资源浪费，提升网络性能。
可选地，作为另一实施例，目标传输资源承载的传输数据量为128比特、216比特或232比特等。
应理解，多个传输资源中的至少一个传输资源能够承载的传输数据量包括128比特、216比特和232比特中的至少一种。目标传输资源具体可以为该至少一个传输资源中的一个。目标传输资源承载的传输数据量还可以为其他比特，本发明实施例并不限于此。
换句话说，多个传输资源可以包括传输数据量大小为128比特的传输资源、传输数据量大小为216比特的传输资源、传输数据量大小为232比特的传输资源中的至少一种。
应理解，每一个传输资源在不同的信道质量或者不同的网络性能下承载的传输数据量可以不同，例如，同一个传输资源在某一信道质量下的传输数据量可以为128比特，在另一信道质量下的传输数据量为216比特等。例如，如表1所示当传输资源为2/4PRB时，ITBS为5时，承载的传输数据量为128比，ITBS为20时，承载的传输数据量为216比特。还应理解，两个不同的传输资源在两个不同的信道质量或网络性能下可以承载相同的传输数据量，例如，两个不同的传输资源承载的传输数据量都可以为128比特、216比特或232比特等，本发明实施例并不对此做限定。例如，如表1所示，当传输资源为2/4PRB，且ITBS为4时，承载的传输数据量为24比特；当传输资源为3/4PRB，且ITBS为2时，承载的传输数据量同样为24比特。
例如，本发明实施例中的业务可以为EVS；如表1所示，多个传输资源包括1/4PRB-3PRB，当传输资源为2/4PRB，ITBS为5时，该传输资源承载的传输数据量为128比特；当传输资源为2/4PRB，ITBS为20时，该传输资源承载的传输数据量为216比特；当传输资源为1PRB，ITBS为6时，该传输资源承载的传输数据量为232比特，等。由于EVS业务传输块(传输数据量)的大小通常为128比特、216比特或232比特等，因此，当多个传输资源包括上述传输资源时，使用上述传输资源进行EVS数据(大小为128比特、216比特或232比特等)传输能够减少或者避免填充比特，减少资源浪费，提升网络性能。
可选地，作为另一实施例，在130之前，本发明实施例还可以包括：
基站确定用户设备支持分数个物理资源块F-PRB的资源分配方式，其中，F-PRB的资源分配方式中分配的传输资源中的最小传输资源小于一个PRB；
基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索 引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源。
具体地，如图1B所示，图1B是根据本发明另一实施例的数据传输的方法的示意流程图，图1所示的方法可以由基站执行，具体地，该方法可以包括：
110，基站确定用户设备支持分数个物理资源块(Fraction-Physical Resource Block，F-PRB)的资源分配方式，其中，F-PRB的资源分配方式中分配的传输资源中的最小传输资源小于一个物理资源块PRB。
换句话说，基站确定用户设备具有支持F-PRB的资源分配方式的能力。例如，基站可以根据高层配置信息确定用户设备支持F-PRB的资源分配方式，或者基站可以根据用户设备上报的能力信息确定用户设备具有支持F-PRB的资源分配方式的能力等，本发明实施例并不对此做限定，其中，高层可以是无线资源控制(Radio Resource Control，RRC)层。
应理解，F-PRB的资源分配方式中的分配资源可以包括分数个PRB和整数个PRB，最小分配资源小于一个PRB，换一种说法最小分配资源为分数个PRB，即最小分配资源为F-PRB，例如，最小分配资源为1/8PRB、1/6PRB、1/4PRB、1/3PRB、1/2PRB或3/4PRB等，本发明实施例并不对此做限定。还应理解，F-PRB的资源分配方式中的分配资源中的次小分配资源也可以小于1个PRB，例如，F-PRB的资源分配方式中的分配资源可以包括最小分配资源的整数倍，例如，最小分配资源为1/4PRB，那么F-PRB的资源分配方式中的分配资源可以包括1/4PRB、1/2PRB、3/4PRB、1PRB、5/4PRB、3/4PRB、7/4PRB和2PRB等。
120，基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源。
其中，该业务可以是小包业务，例如可以是语音业务、语音增强业务EVS或者网页浏览业务等，本发明实施例并不对此做限定。
应理解，索引号可以包括从小到大排列的数字，不同的索引号可以对应不同的信道质量或者不同的网络性能等，例如，检索号的数字越大对应信道质量越好或者网络性能越好，检索号的数字越小对应信道质量越差或者网络性能越差，本发明实施例并不对此做限定。具体地，索引号可以为传输块大 小TBS索引号ITBS。
例如，预设的在不同的索引号下传输资源与传输数据量的对应关系可以为预定义的TBS表格，该TBS表格中包括与信道质量对应的取值为0-26的TBS的索引号ITBS，并包括与取值为0-26的ITBS对应的资源NPRB中传输块的大小(传输数据量)的数值，其中，传输资源中的最小传输资源小于一个PRB。例如，小于一个PRB的最小分配资源可以是1/4PRB、1/8PRB或1/2PRB等，NPRB可以包括最小分配资源的整数倍，例如，最小分配资源为1/4PRB，那么F-PRB的资源分配方式中的分配资源可以包括1/4PRB、1/2PRB、3/4PRB、1PRB、5/4PRB、3/4PRB、7/4PRB和2PRB等，本发明实施例并不对此做限定。
应理解，预设的在不同的索引号下传输资源与传输数据量的对应关系可以是预先设置好的，也可以是基站预先获取或存储的，本发明实施例并不对此做限定。
130，基站向用户设备发送资源指示信息，资源指示信息用于指示基站与用户设备间目标传输资源，目标传输资源为多个传输资源中的一个，其中多个传输资源中的最小传输资源小于一个物理资源块PRB。
具体地，基站通过资源指示信息指示用户设备与基站之间的承载业务数据的目标传输资源，换句话说基站通过资源指示信息通知用户设备基于目标传输资源上接收或发送业务数据。
140，基站基于目标传输资源与用户设备进行数据传输。
具体地，基站基于目标传输资源与用户设备可以进行上行数据的传输也可以进行下行数据的传输。
具体而言，基站调度时，会根据当前传输的业务的数据量，以及可用的RB资源为用户设备分配传输资源，基站会根据预设的在不同的索引号下传输资源与传输数据量的对应关系，例如预定义的TBS表格，分配当前信道条件下可以传输该业务数据量的最少RB资源，由于现有TBS表格的最小资源粒度为1个PRB，因此基站至少要为用户设备分配一个PRB资源用于数据传输。现有技术在当业务的数据量少于一个PRB资源时，为了满足现有资源传输要求，经常需要在物理层的传输块中增加填充比特(padding bit)，影响网络性能，然而本发明实施例中F-PRB的资源分配方式中的最小分配资源小于一个PRB，因此，本发明实施例中的资源分配中的最小分配资源可以 小于一个PRB，能够减少或者避免填充比特，减少资源浪费。
因此，本发明实施例通过预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，由于传输资源中的最小传输资源小于一个PRB，因此，本发明实施例能够避免最小传输资源为1个PRB的限制，减少资源浪费，提升网络性能。
需要说明的是，预定义的预设的在不同的索引号下传输资源与传输数据量的对应关系中的最小分配粒度(资源)可以为1/2PRB或1/4PRB等。例如，该业务可以是语音增强业务EVS，预设的在不同的索引号下传输资源与传输数据量的对应关系为预定义的TBS表格，如表一所示的基于EVS的TBS表格中，最小分配粒度为1/4PRB，其中，传输块所占用的资源NPRB包括1/4PRB、1/2PRB、3/4PRB、1PRB、5/4PRB、3/4PRB、7/4PRB、2PRB、9/4PRB、5/2PRB、11/4PRB和3PRB。
表一，基于EVS的TBS表格
Figure PCTCN2015097004-appb-000001
具体地，EVS是第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)下一代语音编码方案，通过语音编码技术的增强，只需要5.9比特率(kilo bits per second，kbps)的传输速率就可以达到和传统 12.2kbps速率的语音业务相同的语音质量。因此，EVS业务每20ms产生的语音帧对应的MAC PDU大小(假设没有填充比特的情况)要远小于传统AMR语音业务对应的媒体接入控制包数据单元(Medium Access Control Protocal Data Unit，MAC PDU)大小。例如，传统的MAC PDU的大小为320或328比特，本发明实施中的EVS的MAC PDU大小可以为128,216,23或264比特等。因此，表一中的TBS表格中包括大小为128,216,232,264比特的传输数据量。ITBS的取值从0到26,其中，ITBS的取值越大，所对应的信道质量越好。相应的，信道质量越好(ITBS的取值越大)对应同一NPRB中传输的传输块(传输数据量)越大。其中，表一中的资源NPRB中传输的传输块的大小可以是预设的值，也可以根据经验设定的值。
应注意，表一中的TBS表格中仅给出了最小传输资源为1/4PRB的情形，当然，本发明实施例中的小于一个PRB的最小传输资源还可以是1/3PRB、1/6PRB、1/8PRB或1/2PRB等，本发明实施例并不对此做限定。
可选地，作为另一实施例，在120之前，还包括：基站根据业务的业务信息确定使用F-PRB的资源分配方式，其中，业务信息包括业务类型、业务的数据量和无线链路控制RLC缓存量中的至少一种。
具体地，如图2所示的数据传输的方法包括：
210，基站确定用户设备支持F-PRB的资源分配方式，其中，F-PRB的资源分配方式中分配的传输资源中的最小传输资源小于一个物理资源块PRB。
250，基站根据业务的业务信息确定使用F-PRB的资源分配方式，其中，业务信息包括业务类型、业务的数据量和无线链路控制RLC缓存量中的至少一种。
220，基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源。
230，基站向用户设备发送资源指示信息，资源指示信息用于指示基站与用户设备间的目标传输资源，目标传输资源为多个传输资源中的一个，其中多个传输资源中的最小传输资源小于一个物理资源块PRB。
240，基站基于目标传输资源与用户设备进行数据传输。
应理解，210至240分别与图1中的110至140对应，为避免重复，不 再赘述。
因此，本发明实施例根据预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，由于传输资源中的最小传输资源小于一个PRB，因此，本发明实施例能够避免最小传输资源为1个PRB的限制，减少资源浪费，提升网络性能。
具体地，基站首先确定用户设备支持F-PRB的资源分配方式，然后基站再根据业务的业务信息确定使用F-PRB的资源分配方式。之后，基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，基站向用户设备发送资源指示信息，最后，基站基于目标传输资源与用户设备进行数据传输。
具体地，作为另一实施例，业务信息包括业务的业务类型，在250中，当业务的业务类型符合预定义的业务类型时，基站确定使用F-PRB的资源分配方式，其中预定义的业务类型包括能够使用F-PRB的资源分配方式进行数据传输的业务的类型。
具体地，基站首先确定用户设备支持分数个物理资源块F-PRB的资源分配方式，然后基站再根据业务的业务类型符合预定义的业务类型时，确定使用F-PRB的资源分配方式；基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，并基于目标传输资源与用户设备进行数据传输。
其中，预定义的业务类型可以是预先设置好的业务类型，预先设置好的业务类型能够使用F-PRB的资源分配方式进行数据传输。例如，预定义的业务类型可以包括可以是语音业务、语音增强业务EVS或者网页浏览业务等，本发明实施例并不对此做限定。
例如，当前传输的业务为EVS时，EVS业务类型符合预定义的业务类型，基站就可以选择F-PRB的资源分配方式进行资源分配。
可替代地，作为另一实施例，业务信息包括业务的业务量(数据量)或者RLC缓存量，在250中，在业务的业务量或者无线链路控制RLC缓存量小于相应预设阈值时,基站确定使用F-PRB的资源分配方式。
具体地，基站根据业务的业务量小于第一阈值或者RLC缓存量小于第 二阈值确定使用F-PRB的资源分配方式。
换句话说，如果当前业务的业务量小于第一阈值或RLC缓存量小于第二阈值，或在当前信道条件下，当前业务的业务量或RLC层缓存数据量使用F-PRB的资源分配方式相对于传统资源分配方式可以节省PRB资源,基站选择F-PRB的资源分配方式使用本发明实施例中的TBS表格确定与用户设备间业务的传输资源。否则，如果当前时刻待传输的业务量大于第一阈值或RLC缓存量大于第二阈值，或在当前信道条件下，当前时刻待传输的业务量或RLC层缓存数据量使用F-PRB的资源分配方式相对于传统资源分配方式不能够节省PRB资源,基站使用传统的PRB资源分配方式和传统TBS表格确定与用户设备间业务的传输资源。
其中，第一阈值和第二阈值可以根据经验预先设置，也可以根据实际应用来设置，例如，第一阈值为320比特或480比特等，第二阈值为232比特、320比特或480比特等，本发明实施例并不对此做限定。
例如，当前业务为EVS时，结合表一，在ITBS为4时，当前传输的业务量(业务的数据量)为24比特时，结合表一可知仅需要1/2个PRB就可以承载该业务，然而按照传统的资源分配方式至少要分配一个PRB，因此，传输当前业务时，使用F-PRB的资源分配方式相对于传统资源分配方式可以节省PRB资源，在这种情况下基站选择F-PRB的资源分配方式使用本发明实施例中的TBS表格确定与用户设备间业务的传输资源。
可替代地，作为另一实施例，业务信息包括业务的业务类型，和业务的业务量(数据量)或者RLC缓存量，在250中，在业务的业务类型符合预定义的业务类型，且业务的数据量或者RLC缓存量小于相应预设阈值时，基站确定使用F-PRB的资源分配方式。
具体地，基站首先根据高层配置信息确定基站和用户设备支持F-PRB的资源分配方式，然后基站再根据业务的业务类型符合预定义的业务类型时，并且基站根据业务的业务量小于第一阈值或者RLC缓存量小于第二阈值确定使用F-PRB的资源分配方式后，基站确定使用F-PRB的资源分配方式；最后基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，并且基站向用户设备发送资源指示信息，资源指示信息用于指示基站与用户设备间目标传输资源；最后基于目标传输资源与用户 设备进行数据传输。
应理解，根据本发明是实例，基站确定用户设备支持F-PRB的资源分配方式之后，可以不需确定是否使用F-PRB的资源分配方式，基站可以直接根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源。换句话说，基站确定用户设备支持F-PRB的资源分配方式之后，可以不需确定是否使用F-PRB的资源分配方式，基站可以直接采用F-PRB的资源分配方式确定与用户设备间业务的传输资源。
可选地，作为另一实施例，在130中，资源指示信息包括下行控制信息DCI。
可选地，作为另一实施例，基站与用户设备间的业务为上行业务，在120中，基站根据承载上行业务的信道的信道质量确定与信道质量对应的传输块大小TBS索引号ITBS；基站根据业务的数据量和预设的在不同的索引号下传输资源与传输数据量的对应关系，将ITBS下能够承载业务的数据量的最小传输资源确定为目标传输资源。
应理解，本发明实施例中，可以ITBS下能够承载业务的数据量的最小传输资源确定为目标传输资源。也可以将ITBS下能够承载业务的数据量的传输资源确定为目标传输资源，在这种情况下目标传输资源可以为ITBS下能够承载业务的数据量的最小传输资源，也可以为大于ITBS下能够承载业务的数据量的最小传输资源的传输资源。
可选地，作为另一实施例，在140中，基站基于目标传输资源接收用户设备发送的上行业务的数据。
具体地，在基站与用户设备间的业务为上行业务时，基站确定用户设备支持F-PRB的资源分配方式，然后基站根据业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资源，例如，基站根据承载上行业务的信道的信道质量,从TBS信息中确定与信道质量对应的传输数据量索引号ITBS；基站根据业务的数据量为用户设备分配当前ITBS下能够承载数据量的最小资源，最后，基站基于最小资源接收上行业务数据。
可替代地，作为另一实施例，基站与用户设备间的业务可以为下行业务，本发明实施例方法还可以包括：基站接收用户设备发送的承载下行业务的信 道的信道质量，在120中，基站根据信道质量确定与信息质量对应的索引号ITBS；基站根据业务的数据量和预设的传输数据量与传输资源的对应关系，将ITBS下能够承载业务的最小资源确定为目标传输资源。
应理解，本发明实施例中，可以ITBS下能够承载业务的数据量的最小传输资源确定为目标传输资源。也可以将ITBS下能够承载业务的数据量的传输资源确定为目标传输资源，在这种情况下目标传输资源可以为ITBS下能够承载业务的数据量的最小传输资源，也可以为大于ITBS下能够承载业务的数据量的最小传输资源的传输资源。
进一步地，作为另一实施例，在140中，基站基于目标传输资源向用户设备发送下行业务的数据。
具体地，在基站与用户设备间的业务为下行业务时，基站首先确定用户设备支持F-PRB的资源分配方式，基站接收用户设备发送的承载下行业务的信道的信道质量，然后根据业务的数据量，和预设的在不同的信道质量下的传输资源与传输数据量的对应关系确定基站与用户设备间承载业务的目标传输资，例如，基站根据信道质量，从TBS信息中确定与信息质量对应的传输数据量索引号ITBS；基站根据据缓存中的业务的数据量为用户设备分配当前ITBS下能够承载数据量的最小资源；最后，基站基于最小资源发送下行业务数据。
可选地，作为另一实施例，F-PRB的资源分配方式中所对应的传输块包括大小为128比特、216比特和232比特中的至少一种。
进一步地，在较佳实施例中，本发明实施例中的业务为EVS；预设的在不同的信道质量下的传输资源与传输数据量的对应关系为TBS表格，其中，TBS表格中包括至少一个不大于一个PRB的资源在ITBS小于或等于9时传输数据的大小为128比特、216比特或232比特。这样能够增加EVS业务的重传次数，提供更多的时间分集增益。并且EVS业务传输块的大小通常为128比特、216比特或232比特，因此，能够减少或者避免填充比特，减少资源浪费，提升网络性能。
应理解，本发明实施例中的用户设备可以是支持F-PRB的资源分配方式的设备。
需要说明的一点是，本发明实施例中基站还可以根据高层配置信息确定使用本发明实施例的F-PRB的资源分配方式还是使用传统PRB资源分配方 式，例如基站可以根据RRC的配置信息确定用户设备支持F-PRB的资源分配方式，那么基站可以使用F-PRB的资源分配方式进行资源分配。对于基站根据RRC的配置信息确定用户设备不支持F-PRB的资源分配方式的，基站可以使用传统的PRB资源分配方式和传统TBS表格进行资源分配，因此，本发明实施例可以根据用户设备的能力选择传输表格进行资源分配，避免对传统用户设备的影响。
应注意，在本发明实施例中，如果基站选择了F-PRB的资源分配方式，但是传输数据需要的PRB的个数大于本发明实施例中预定义的TBS表格中的最大PRB个数时，基站恢复使用传统的TBS表格进行资源分配。因此，本发明实施例中基站可以灵活的选择使用本发明实施例中的预定的TBS表格或者传统的TBS表格进行资源分配。
上文中，结合图1A、图1B和图2从基站侧描述了根据本发明实施例的用于数据传输的方法。下面结合图3从用户设备侧对本发明实施例的用于数据传输的方法进行详细描述。
图3是根据本发明另一实施例的用于数据传输的方法的示意流程图，图2所示的方法可以由用户设备执行，具体地，该方法包括：
310，用户设备接收基站发送的资源指示信息，资源指示信息用于指示基站与用户设备间的目标传输资源，其中，目标传输资源由基站根据基站与用户设备间传输的业务的数据量，和预设的在不同的索引号下传输资源与传输数据量的对应关系确定的，其中传输资源中的最小传输资源小于一个PRB。
320，用户设备基于目标传输资源与基站进行数据传输。
因此，本发明实施例通过用户设备接收基站发送的资源指示信息，资源指示信息用于指示基站与用户设备间的目标传输资源，并基于目标传输资源与基站进行数据传输，由于传输资源中的最小传输资源小于一个PRB，因此，本发明实施例能够避免最小传输资源为1个PRB的限制，减少资源浪费，提升网络性能。
可选地，作为另一实施例，业务为下行业务，方法还包括：用户设备向基站发送承载下行业务的信道的信道质量，以使得基站根据信道质量确定基站与用户设备间的目标传输资源,其中，在320中，用户设备基于目标传输资源接收基站发送的下行业务的数据。
可替代地，作为另一实施例，业务为上行业务，在320中，用户设备基于目标传输资源向基站发送上行业务的数据。
具体而言，当该业务为上行业务时，用户设备向基站发送用户设备缓存中的数据量(业务的数据量)，以使得基站根据承载业务的信道的信道质量、用户设备缓存中的数据量和预设的在不同的索引号下传输资源与传输数据量的对应关系确定目标传输资源。或者，该业务为下行业务，用户设备向基站发送信道质量信息，基站根据用户设备上报的信道质量、业务的数据量和预设的在不同的索引号下传输资源与传输数据量的对应关系确定目标传输资源。
其中，用户设备和基站间的业务可以是小包业务，例如可以是语音业务、语音增强业务EVS或者网页浏览业务等，本发明实施例并不对此做限定。

应理解，预设的在不同的索引号下传输资源与传输数据量的对应关系可以是预先设置好的，也可以是基站预先获取或存储的，本发明实施例并不对此做限定。
可选的，作为另一实施例，资源指示信息包括下行控制信息DCI。
可选的，作为另一实施例，最小传输资源包括1/8PRB、1/6PRB、1/4PRB、1/3PRB、或1/2PRB等。
可选地，作为另一实施例，目标传输资源承载的传输数据量为128比特、216比特或232比特。
换句话说，目标传输资源承载的基站与用户设备间传输的业务的数据量为128比特、216比特或232比特。
例如，本发明实施例中的用户设备与基站间的业务为EVS，预设的在不同的索引号下传输资源与传输数据量的对应关系为TBS表格，其中，TBS表格中包括至少一个不大于一个PRB的资源在ITBS小于或等于9时传输数据的大小为128比特、216比特或232比特。这样能够增加EVS业务的重传 次数，提供更多的时间分集增益。并且EVS业务传输块的大小通常为128比特、216比特或232比特，因此，能够减少或者避免填充比特，减少资源浪费，提升网络性能。
应理解，图3的方法与图1A、图1B和图2的方法相对应，图3中所示的用户设备能够实现图1A、图1B和图2方法中涉及用户设备的各个过程，为避免重复，不再赘述。
