具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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它实施例，都属于本申请保护的范围。
本申请实施例适用于无线通信系统，尤其适用于长期演进(Long Term Evolution，LTE)系统，适合处理具有低时延要求的数据传输场景。
为了进一步降低用户终端的上行传输时延，本申请实施例采用短周期SPS资源分配模式，即采用缩短SPS周期的方法，使用户终端能够在更短的时间内获得传输机会。
本申请实施例应用的系统架构如图1所示，无线通信系统100包括基站101,和用户终端102。其中，基站101负责分配上行空口资源，并将调度结果指示给用户终端102；用户终端102用于接收基站101的上行调度指示，并根据自身缓存情况发送数据。
下面将结合附图对本申请实施例提供的方法作进一步详细说明。
参阅图2所示，本申请实施例提供的方法流程如下。本申请实施例以下所述的用户终端为基站调度的任意一个用户终端。
步骤201：基站向用户终端通知半静态调度SPS周期，所述SPS周期为 短周期；
本申请实施例所述的短周期用于指示，SPS周期包含的子帧个数小于标准SPS周期配置中的最小值，现有标准中SPS周期一般最小设置为10ms，即10个子帧的长度，所以，上述短周期用于指示SPS周期中包含的子帧个数小于10。
例如，SPS周期缩短至5ms，或2ms，最短可缩短至1ms。可扩展的，SPS周期也可以更短，如0.5ms，0.2ms，0.1ms等。SPS周期的单位可以是ms，或者是子帧个数，或者是传输时间间隔(英文：Transmission Time Interval，缩写：TTI)数，或者OFDM符号个数，本发明不作限制。
不失一般性的，所述SPS周期也可以是现有技术中的10ms，20ms等值，本发明各实施例，也同样适用所述SPS周期也可以是现有技术中的10ms，20ms等值。
具体地，基站可以在向用户终端发送的无线资源控制(英文：Radio Resource Control，缩写：RRC)消息中携带SPS周期的配置信息。
步骤202：用户终端接收基站配置的SPS周期。
具体地，用户终端接收基站发送的RRC消息，通过RRC消息中携带的SPS周期配置信息确定SPS周期。
步骤203：基站为用户终端分配第一SPS资源。
为方便说明，本申请实施例中将在本步骤中基站为用户终端分配的SPS资源称为第一SPS资源。
具体地，基站通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)下发SPS激活消息，在SPS激活消息中指示SPS资源的位置。
由于本申请实施例中SPS周期缩短，假设缩短为1ms，那么用户终端在每一个上行子帧上都有传输机会。若基站分配给用户终端的单次SPS资源的大小根据用户终端单次数据量的上限设置，而用户终端并不会每次都按照最大数据量传输，这样必定会造成单次的数据传输资源浪费。
较佳的，本申请实施例中，基站为用户终端分配第一SPS资源可以但不 限于按照以下方式：用户终端在一个SPS周期中可用的第一SPS资源大小根据用户终端在一个SPS周期中发送数据量的最小值设置。
举例来说，基站为用户终端分配的在一个SPS周期可用的第一SPS资源适用于传输缓存状态报告(英文：Buffer State Report，缩写：BSR)或其他与BSR数据量相等或接近的小数据包。
步骤204：用户终端确定基站分配的第一SPS资源。
具体地，用户终端接收基站下发的SPS激活消息，通过SPS激活消息中携带的信息，确定基站分配的第一SPS资源的位置。
步骤205：用户终端按照所述SPS周期，占用第一SPS资源周期性向所述基站发送数据。
在SPS配置生效后，用户终端就可以在每个SPS周期，在第一SPS资源位置发送数据。
步骤206：基站接收用户终端基于所述SPS周期、占用第一SPS资源周期性发送的数据。
以上是本申请实施例中提供的基于半静态调度的数据传输方法的基本流程。下面结合具体的实施例进行更详细的描述。
需要统一说明的是，图3-图7中网格区域表示用户终端占用SPS资源发送数据。
以频分双工(英文：Frequency Division Duplex，缩写：FDD)模式为例，SPS周期缩短为2ms时SPS调度过程如图3所示。基站在子帧(n-2)向用户终端发送RRC消息，在RRC消息中携带SPS周期等配置；在子帧n通过PDCCH下发SPS激活消息，在SPS激活消息中指示具体的SPS频域资源位置等信息；在子帧(n+4)SPS配置生效，用户终端在子帧(n+4)以及后续每个SPS周期在相同的频域资源上发送数据，直到基站下发SPS资源释放消息为止。
若SPS周期缩短至1ms，那么用户终端就可以在每个上行子帧都有上行传输机会。这样虽然能够缩短用户终端的上行传输时延，但是若用户终端并不是在每个上行子帧上都有数据要发送，无疑会造成部分子帧空置，导致系统 资源浪费。
基于上述考虑以及通过缩短SPS周期带来的一些其他问题，较佳的，基于图2所示的方法，本申请实施例进一步提出了优化方案，用以在缩短上行传输时延的基础上解决系统资源浪费的问题。
优化方案一：
基站为所述用户终端配置激活长度参数，所述激活长度参数用于指示在一个SPS周期内的连续可用的子帧个数；
用户终端接收所述基站配置的激活长度参数，并按照所述激活长度参数，在所述SPS周期内占用连续可用的子帧发送数据。
具体来说，基站根据用户终端的业务特征，确定用户终端发送数据需要占用的时间长度，进一步确定激活长度参数。
用户终端在一个SPS周期内，占用连续可用的子帧发送数据，不用等待多个SPS周期的发送机会，能够有效的缩短上行传输时延；并且，基站可以释放SPS周期内除用户终端占用的连续的子帧外的空闲子帧，这样就可以将SPS资源中用户终端不需要使用的资源划分出来，用作他用，降低了系统资源的浪费。
举例来说，如图4所示，基站为用户终端配置的SPS周期为8ms，基站根据用户终端的业务特征，确定用户终端单次发送数据需要占用的时间长度为4ms，则通过激活长度参数向用户终端指示在一个SPS周期内可占用连续的4个子帧发送数据。
当然，上述优化方案一不仅适用于短周期SPS调度的应用场景，还适用于长周期SPS调度的应用场景。
优化方案二：用户终端占用连续的SPS周期中的第一SPS资源，向所述基站发送初传数据和针对所述初传数据的至少一次重传数据；
基站接收所述用户终端发送的初传数据和针对所述初传数据的至少一次重传数据，所述初传数据和所述至少一次重传数据占用连续的SPS周期中的所述第一SPS资源。
其中，所述至少一次重传数据与所述初传数据包含的内容相同；或，所述至少一个重传数据与所述初传数据携带不同的增量冗余信息。
较佳的，所述用户终端在占用连续的SPS周期，向所述基站发送初传数据和针对所述初传数据的至少一次重传数据的过程中，向所述基站发送连续传输次数。
具体地，现有技术中，一个混合自动请求重传(英文：Hybrid Automatic Repeat reQ用户终端st，缩写：HARQ)周期一般为8ms，用户终端在发送完初传数据后，若基站反馈了否定(英文：NACK)消息，用户终端需要向基站发送重传数据，但发送初传数据后经过8ms才能发送一次重传数据。通过本申请实施例上述优化方案二，用户终端在短周期SPS调度下，在连续SPS周期上发送初传数据和至少一次重传数据，即在发送完初传数据后，无需等待基站反馈的NACK消息，直接向基站发送重传数据，这样能够增强数据传输的可靠性，能够更快的使基站解析出正确的数据。
初传数据与重传数据可以是简单的重复，即包含相同的内容；也可以按照HARQ重传的模式，即使用不同的冗余版本，在初传数据和重传数据中携带不同的增量冗余信息。
可以是基站规定连续传输次数，并通知给用户终端；也可以是用户终端根据信道状况等信息确定任意的连续传输次数，并通知给基站，所述连续传输次数表示初传数据和重传数据传输的总次数。具体通知方式，可以通过MAC层的CE(简称为MAC CE)显示通知，也可以通过向基站发送导频信号，通过导频信号中的循环移位值直接或间接的表征连续传输次数。其中，采用循环移位值直接表征连续传输次数，例如，循环移位值3表征连续传输次数为3次；采用循环移位值间接表征连续传输次数，例如，解调参考信号(英文：Demodulation reference signal，缩写：DMRS)配置表中循环移位值3对应的索引值为2，则表征连续传输次数为2次。
下面对上述优化方案二进行举例说明。
仍以FDD模式为例，假设SPS周期为1ms。
假设用户终端待发送的数据在单个子帧的SPS资源上能发送完成。
如图5a所示，现有技术中，用户终端在子帧n的SPS资源上发送初传数据，若在子帧(n+4)收到基站反馈的NACK消息，则需要在子帧n+8发送重传数据。这样，基站接收用户终端发送的初传数据和一次重传数据需要经过9ms。
如图5b所示，本申请实施例中，用户终端在子帧n的SPS资源上发送初传数据，若连续传输次数为2次，则在子帧(n+1)的SPS资源上接着发送重传数据。基站在子帧(n+1)之后的第4个子帧即子帧(n+5)上指示ACK/NACK消息。由于基站直接接收到了用户终端发送的初传数据和重传数据，则基站能够成功接收数据的可能性大大提高，若基站成功接收数据，则在子帧(n+5)向用户终端反馈ACK消息。若基站仍旧不能成功接收数据，则在子帧(n+5)向用户终端反馈NACK消息。当用户终端接收到基站反馈的NACK消息后，在子帧(n+9)和子帧(n+10)向基站继续发送重传数据。
这样，基站接收用户终端发送的初传数据和一次重传数据需要经过6ms。
当然，若用户终端待发送的数据需要占用两个或两个以上子帧的SPS资源才能发送完成，则用户终端对每个子帧的SPS资源上发送的初传数据都按照如上所述的发送方式进行重复传输。例如，如图5c所示，用户终端待发送的数据需要占用两个子帧的SPS资源，将用户终端待发送的数据在两个子帧的SPS资源上发送的两个数据块用符号1和2表示，用户终端在子帧n上发送数据块1的初传数据，在子帧(n+1)上发送数据块1的重传数据，在子帧(n+2)上发送数据块2的初传数据，在子帧(n+3)上发送数据块2的重传数据，通过这种连续传输的方式，能够增强数据传输的可靠性，基站更能够成功接收数据。若基站仍不能成功接收到数据，则在子帧(n+5)和子帧(n+7)上分别向用户终端反馈数据块1和数据块2的NACK消息。用户终端在子帧(n+9)和子帧(n+10)上分别继续向基站发送数据块1的重传数据，在子帧(n+11)和子帧(n+12)上分别继续向基站发送数据块2的重传数据。
较佳的，上述优化方案二适用于用户终端待发送的数据需要占用的时间 长度不大于一个HARQ周期。
通过上述优选方案二提供的连续传输初传数据和重传数据的方法，能够有效减少上行传输时延，并增强传输的可靠性，能够使基站更快的成功接收到用户终端发送的数据，提高了系统的资源利用率。
优选方案三：鉴于当前LTE协议规定，对于SPS资源默认用于数据新传，尤其针对本申请实施例短周期SPS调度的场景，非自适应重传也可能发生在SPS资源上，所以SPS资源上可能出现新传和重传数据冲突，按当前协议规定，这种情况下，重传会被丢弃只会执行新传，这会降低传输可靠性。本申请实施例中，基站在为用户终端分配第一SPS资源后，在接收用户终端发送的数据之前，向用户终端指示第一传输规则，所述第一传输规则包括：当重传数据和初传数据在第一SPS资源发生冲突时，优先发送重传数据。以增强数据传输的可靠性。
所述第一传输规则可以在协议中规定，如当SPS周期小于或等于某个门限值时，该第一传输规则生效，其中所述某个门限值可以是2ms，1ms，2个子帧，1个子帧，2个OFDM符号，1个OFDM符号等，本申请中不作限制；所述第一传输规则可以在协议中规定，如当SPS周期小于或等于某个门限值时且配置或启动了上行授权忽略功能或启动了优化方案六中的第二传输规则时，该第一传输规则生效，其中所述某个门限值可以是2ms，1ms，2个子帧，1个子帧，2个OFDM符号，1个OFDM符号等，本申请中不作限制，其中所述配置或启动了上行授权忽略功能，表示用户终端在没有有效上行数据时，或者没有有效上行数据及常规MAC CE(如常规BSR，和/或PHR等)时，不在所述上行授权指示的资源上发送上行信息；或者所述传输规则可以通过RRC消息发送给用户终端。。
优选方案四：鉴于在基站为用户终端分配承载数据量较小的SPS资源的基础上，若用户终端待发送的数据较大，会占用传输时间较长的弊端，本申请实施例设计方案为：
用户终端占用所述第一SPS资源向基站发送BSR，所述BSR中携带所述 用户终端待发送的数据量；
基站接收到用户终端发送的BSR，根据所述BSR执行以下操作：为所述用户终端分配物理上行共享信道(英文：Physical Uplink Shared Channel，缩写：PUSCH)资源；或者，为所述用户终端分配第二SPS资源，所述第二SPS资源能够承载的数据量大于所述第一SPS资源能够承载的数据量。
为所述用户终端分配PUSCH资源，具体为：基站通过向用户终端发送第一指示消息来通知用户终端为其分配的PUSCH的位置，即在第一指示消息中携带为用户终端分配的PUSCH资源的信息。
考虑到用户终端在占用PUSCH资源发送完较大的数据包后，可能会有一段时间不再需要发送数据，若继续维持第一SPS资源的调度，无疑会造成资源浪费。
较佳的，本申请实施例中，在上述第一指示消息中还携带SPS冻结指示信息，所述SPS冻结指示信息用于指示所述用户终端：在占用所述PUSCH资源发送数据后，在设定的冻结时间内停止对所述第一SPS资源的占用，并在所述冻结时间结束时，恢复对所述第一SPS资源的占用。上述设定的冻结时间也可以设定为冻结次数，用于表征一定次数的SPS周期。
例如，如图6所示，用户终端在子帧n向基站发送BSR，基站在子帧n+4，通过在PDCCH上使用一个下行控制信息(英文：Downlink Control Information，缩写：DCI)指示用户终端可用的PUSCH资源，用户终端在子帧(n+8)占用基站指示的PUSCH资源发送数据，假设冻结时间为3ms，则用户终端在子帧(n+9)到子帧(n+11)停止占用第一SPS资源，在子帧(n+12)恢复占用第一SPS资源。
为所述用户终端分配第二SPS资源，具体为：基站通过重新激活一个SPS资源的方式，即基站向用户终端发送激活消息，在激活消息中携带为用户终端分配的所述第二SPS资源。
较佳的，基站根据BSR中用户终端待发送的数据量，确定为用户终端调度第二SPS资源的时长，并根据该时长，在激活消息中携带生效时间，所述 激活消息用于指示所述用户终端：在所述生效时间内允许占用所述第二SPS资源发送数据，在所述生效时间结束时，停止对所述第二SPS资源的占用，并恢复对所述第一SPS资源的占用。可选的，基站也可以通过PDCCH向用户终端发送释放命令，该释放命令用于释放第二SPS资源，并恢复第一SPS资源的占用。
例如，如图7所示，用户终端在子帧n向基站发送BSR，基站通过PDCCH为用户终端分配第二SPS资源。假设生效时间为4ms，用户终端在子帧(n+8)至子帧(n+11)占用第二SPS资源。基站提前通过PDCCH发送释放命令，用户终端根据释放命令，在子帧(n+12)停止占用第二SPS资源，并恢复占用第一SPS资源。
这样，通过上述优化方案四，针对用户终端待传输数据量较大的情况，单独调度PUSCH资源，并采用时间设置机制，使得在用户终端发送完待传输数据后，在一段时间内释放为用户终端分配的小块的第一SPS资源；或者，针对用户终端待传输数据量较大的情况，重激活大块的第二SPS资源的方式，并采用时间设置机制，使得在用户终端发送完待传输数据后，及时释放大块的第二SPS资源，恢复之前小块的第一SPS资源。这样，能够实现快速调度用户终端待传输的较大数据量的数据，并能够减少系统资源浪费和控制开销。
优化方案五、所述用户终端在确定不需要占用所述第一SPS资源时，向所述基站发送第二指示消息，所述第二指示消息用于指示所述基站释放所述第一SPS资源；或者，所述第二指示消息用于指示所述基站在预定时间段内释放所述第一SPS资源，并在所述预定时间段结束后，将所述第一SPS资源重新调度给所述用户终端；
所述基站接收所述用户终端发送的第二指示消息；若所述第二指示消息用于指示所述用户终端不需要继续占用所述第一SPS资源，则所述基站释放所述第一SPS资源；或者，若所述第二指示消息用于指示所述用户终端在预定时间段内不需要占用所述第一SPS资源，则所述基站在所述预定时间段内释放所述第一SPS资源，并在所述预定时间段结束时，重新为所述用户终端 调度所述第一SPS资源。
具体地，用户终端向基站发送第二指示消息的方式可以是，向所述基站发送导频信号，并采用导频信号中的循环移位值表征第二指示消息；也可以是，通过MAC CE向所述基站发送第二指示消息。
例如，用户终端在确定不需要占用第一SPS资源时，在导频符号上发送DMRS导频，采用预定义的循环移位值来表征第二指示消息，第二指示消息用于指示所述用户终端不需要继续占用所述第一SPS资源。如，循环移位值3代表不需要继续占用所述第一SPS资源，较佳的，第二指示消息还可以指示基站临时释放第一SPS资源；基站在收到DMRS导频信号后，按照循环移位值临时释放第一SPS资源，并可以将第一SPS资源用作他用；又如，用户终端在希望重新占用第一SPS资源时，采用循环移位值5表征希望继续占用所述第一SPS资源，基站在收到DMRS导频信号后，按照循环移位值恢复用户终端对第一SPS资源的占用。
又例如，用户终端在确定不需要占用第一SPS资源时，在导频符号上发送DMRS导频，采用预定义的循环移位值来表征第二指示消息，第二指示消息用于指示所述用户终端在预定时间段内不需要占用所述第一SPS资源。如，预定时间段的时间起点可以是当前子帧或任意一个预定义的子帧，时长可以设置与循环移位值相关的任意计算方式，如，时长为循环移位值与T的乘积，T为任意预设值或已通过RRC消息指示。基站在收到用户终端上报的消息后，在上述预设时间段内释放第一SPS资源，并用作他用，在上述预设时间段结束时，恢复用户终端对第一SPS资源的占用。
又例如，用户终端在确定不需要占用第一SPS资源时，通过MAC CE向基站上报不需要继续占用所述第一SPS资源，则基站释放所述第一SPS资源。
又例如，用户终端在确定不需要占用第一SPS资源时，通过MAC CE向基站上报在预定时间段内不需要占用第一SPS资源，预定时间段的时间起点可以是当前子帧或任意一个预定义的子帧，时长通过用户终端向基站上报的消息中携带。基站在收到用户终端上报的消息后，在上述预设时间段内释放 第一SPS资源，并用作他用，在上述预设时间段结束时，恢复用户终端对第一SPS资源的占用。
这样，通过用户终端辅助的调度方式，能够在用户终端没有数据发送时，及时释放用户终端占用的SPS资源，将释放的SPS资源用作他用，提高了资源利用率，并避免了系统资源的浪费。
优化方案六、鉴于用户终端在没有数据发送时，需要发送填充(英文：padding)数据包，尤其针对本申请实施例中在短周期的SPS应用场景下，用户终端并不是在每个SPS周期都有数据要发送，因此发送padding数据包的次数要增多，对于用户终端电量和系统资源都是浪费的。在优化方案六中，在用户终端发送数据之前，确定第二传输规则，所述第二传输规则包括：(1)用户终端在不发送MAC层的业务数据单元(英文：Service Data Unit，缩写：SDU)、且不发送特定MAC CE的子帧上，不发送padding数据包，即忽略上行授权，其中，所述特定MAC CE包括：常规BSR，周期性BSR，PHR中的一个或多个；在(1)使能的情况下，用户终端在没有MAC层的SDU(简称MAC SDU)需要发送时，不发送周期性的BSR和/或PHR。用户终端根据基站指示的第二传输规则，在没有MAC SDU和特定MAC CE发送时，不发送padding数据包，即忽略上行授权；此时，周期性的BSR和/或PHR上报需要和MAC SDU绑定发送，即只有在发送MAC SDU时，才可以发送周期BSR和/或PHR。
所述第二传输规则可以在协议中规定，或者所述传输规则可以通过RRC消息发送给用户终端。本申请中不作限制。。
通过上述优化方案六，能够节省用户终端电量，并避免系统资源浪费。
优化方案七、鉴于在用户终端不发送任何数据的时长超过时间校准计时器(英文：TA Timer)的情况下，会失去上行同步的问题，本申请实施例中，用户终端在停止使用所述第一SPS资源发送任何数据时，启动定时器；在所述定时器超时时，若确定在所述定时器的计时时间内未向所述基站发送任何数据，则向所述基站发送数据；所述定时器的计时时间小于TA计时器。
具体地，在定时器超时时，用户终端通过第一SPS资源发送任意数据，例如，可以发送Padding数据包，以保证用户终端上行同步。
优化方案八、鉴于时分双工(英文：Time Division Duplexing，缩写：TDD)LTE系统有不同的上下行子帧配比，上下行转换点周期通常为5/10ms，尤其针对本申请实施例短周期的SPS调度的场景，可能出现SPS配置的子帧不是可用的上行子帧的情况。本申请实施例中：
针对在时分双工TDD系统中，所述基站在接收所述用户终端发送的数据之前，根据第三传输规则确定SPS占用子帧；所述SPS占用子帧即用户终端按照SPS周期发送数据所占用的子帧。
所述第三传输规则包括如下三种中的任一个：1、在所有类型的子帧(包括下行子帧，上行子帧和特殊子帧)占用的时间内按照所述SPS周期确定SPS占用子帧，其中，若在任一SPS周期内确定的SPS占用子帧为上行子帧，则可以占用所述上行子帧发送数据，若在任一SPS周期内确定的SPS占用子帧为非上行子帧，即下行子帧或特殊子帧，则放弃占用所述非上行子帧；或者，2、在所有上行子帧占用的时间内按照所述SPS周期确定SPS占用子帧，并可以占用子帧发送数据；或者，3、在所有类型的子帧占用的时间内按照所述SPS周期确定SPS占用子帧，并可以占用所述SPS占用子帧发送数据，其中，在确定SPS占用子帧的过程中，若确定的SPS占用子帧为非上行子帧，则确定所述非上行子帧之后的第一个上行子帧为SPS占用子帧。后续可以该第一个上行子帧为起点计算后续SPS占用子帧，或者仍按照原周期计算SPS占用子帧。
所述第三传输规则可以在协议中规定，或者所述传输规则可以通过RRC消息发送给用户终端。本发明不作限制。
以下以SPS周期为2ms且TDD子帧配比0为例，并结合附图对上述规则中的第1、2、3种情况进行说明。
第1种情况如图8所示，D0、D1、D5、D6为下行子帧，U2、U3、U4、U7、U8、U9，为上行子帧，用户终端在所有类型的子帧占用的时间内按照 2ms的SPS周期选择待用子帧，当选择的待用子帧为不可用子帧(包括下行子帧和特殊子帧)时，放弃并继续选择下一个SPS周期中的待用子帧，如图8中，子帧D6和D0为下行子帧，则选择跳过。
第2种情况如图9所示，D0、D1、D5、D6为下行子帧，U2、U3、U4、U7、U8、U9，为上行子帧，用户终端仅在上行子帧占用的时间内按照2ms的SPS周期占用子帧发送数据，这样便不会出现待用子帧为不可用子帧的情况。
第3种情况如图10所示，D0、D1、D5、D6为下行子帧，U2、U3、U4、U7、U8、U9，为上行子帧，用户终端仍在所有类型的子帧占用的时间内按照2ms的SPS周期选择待用子帧，当碰到选择的子帧为不可用子帧时，放弃选择这个不可用子帧，而是跳到下一个可用子帧，将该下一个可用子帧选为待用子帧。例如，当碰到D6为不可用子帧时，放弃选择D6，而是选择U7为待用子帧。后续SPS子帧，如果以U7为起点，根据2ms周期计算得到的下一个SPS子帧为U9，如图10所示；可选的，也可以仍按照原周期计算SPS子帧，则下一个SPS子帧为U8。
通过上述优选方案八解决了TDD系统中，在短周期的SPS调度的场景，出现SPS配置的子帧不是可用的上行子帧的问题。
优化方案九、在优化方案六基础上，鉴于用户终端在没有数据发送时，上行探测参考信号(英文：Sounding Reference Signal，缩写：SRS)和/或周期性物理上行控制信道(Physical Uplink Control Channel，缩写：PUCCH)信号的发送，会浪费用户终端电量，并产生上行干扰。
在本优化方案九中，基站确定第四传输规则，并向用户终端指示所述第四传输规则；
所述第四传输规则包括：用户终端在确定不需要占用所述第一SPS资源发送数据时，配置或启动忽略上行授权；
在配置或启动忽略上行授权时，不发送周期性SRS和PUCCH；或者，
在配置或启动忽略上行授权后，执行忽略上行授权的次数达到第一门限 值或执行忽略上行授权的时间达到第二门限值时，不发送周期性SRS和PUCCH。
用户终端确定基站指示的第四传输规则，并按照所述第四传输规则传输数据。在配置或启动忽略上行授权时，不发送周期性SRS和PUCCH；或者忽略上行授权时，且忽略上行授权的次数达到某个门限值N时，不发送周期性SRS和PUCCH，其中所述某个门限值N为1，2，3等自然数；或者忽略上行授权时，且忽略上行授权的时间达到某个门限值K时，不发送周期性SRS和PUCCH，其中所述某个门限值K大于等于0。
所述第四传输规则可以在协议中规定，或者所述传输规则可以通过RRC消息发送给用户终端。本发明不作限制。
通过上述优化方案九，能够节省用户终端电量，并减少上行干扰。
需要说明的是，本申请实施例上述图2所示的方法、优化方案一至优化方案八可以任意结合使用。
