Description

用于请求上行传输资源的方法、终端和网络设备 技术领域
本申请涉及通信领域，并且更具体地，涉及用于请求上行传输资源的方法、终端和网络设备。
背景技术
随着智能城市、大数据时代的来临，无线通信将实现万物连接。目前已经出现了大量物与物的联接，这些物与物之间的联接大多通过蓝牙、Wi-Fi等短距通信技术承载，并非是通过运营商移动网络。为了满足不同物联网(Internet of things，IoT)业务的传输需求，第三代合作伙伴计划(the 3rd Generation Partnership Project，3GPP)基于物联网业务特性和移动通信网络特点，开展了增强移动通信网络功能的技术研究以适应蓬勃发展的物联网业务需求。
基于蜂窝网络的窄带物联网(Narrow Band-IoT，NB-IoT)成为万物互联网络的一个重要分支。NB-IoT构建于蜂窝网络，只消耗大约180KHz的带宽，可直接部署于全球移动通信系统(Global System for Mobile Communication，GSM)网络、通用移动通信系统(Universal Mobile Telecommunications System，UMTS)网络或长期演进(Long Term Evolution，LTE)网络，以降低NB-IoT的部署成本、实现平滑升级。
然而，在目前的NB-IoT中，终端有上行数据需要发送，但是没有上行传输资源时，该终端只能通过向网络设备发起随机接入过程，向网络设备请求用于传输上行数据的上行传输资源，也就是说，即使终端已经通过随机接入过程接入网络设备，该终端需要向网络设备请求上行传输资源时，只能重新发起随机接入过程，向网络设备请求上行传输资源。因此，上述通过随机接入过程向网络设备请求上行传输资源的方式不够灵活。
发明内容

第一方面，提供一种用于请求上行传输资源的方法，包括：终端确定向网络设备发送第一请求时存在冲突，其中，所述第一请求用于请求所述网络设备给所述终端调度上行传输资源；所述终端根据预设规则，调整所述第一请求的发送方式。
在本申请实施例中，终端可以通过第一请求向网络设备请求上行传输资源，避免了现有技术中，终端只能通过发起随机接入流程向网络设备请求上行传输资源，以提高终端向网络设备请求上行传输资源的灵活性。
进一步地，终端通过第一请求向网络设备请求上行传输资源，在一定程度上减少了终端通过随机接入过程请求上行传输资源产生的时延，并且避免了终端由于发起随机接入过程失败，导致的请求上行传输资源失败，有利于提高终端请求上行传输资源的效率。

在NB-IoT中，为了提高终端请求上行传输资源的灵活性，避免现有技术中终端只能通过重新向网络设备发起随机接入过程请求上行传输资源，为终端引入调度请求(Scheduling Request，SR)机制。也就是说，类似于现有的LTE通信系统中终端基于SR机制向网络设备请求上行传输资源的方法，在NB-IoT中，终端也可以通过SR机制向网络设备请求上行传输资源。下文结合图2详细介绍终端基于SR机制的请求上行传输资源的方法。
图2是本申请实施例的请求上行传输资源的方法的示意性流程图。图2所示的方法包括：
210，终端向网络设备发送SR。
具体地，当终端有待传输的上行数据需要向网络设备传输时，终端可以向网络设备发送SR，该SR用于指示所述终端有待传输的上行数据需要传输。
220，网络设备向终端发送第一上行授权(Uplink Grant，UL Grant)信息。
具体地，该第一上行授权信息用于指示终端传输缓冲状态报告(Buffer Status Report，BSR)所使用的传输资源。
需要说明的是，网络设备可以通过NPDCCH向终端发送第一上行授权信息，上述第一上行授权信息指示的用于传输BSR的传输资源可以是窄带物理上行共享信道(Narrowband Physical Uplink Shared Channel，NPUSCH)对应的传输资源。
230，终端向网络设备发送BSR。
具体地，终端可以在上述第一上行授权信息指示的传输资源上向网络设备发送BSR，该BSR用于指示终端待传输的上行数据的数据量。
240，网络设备向终端发送第二上行授权信息。
具体地，网络设备向终端发送第二上行授权信息，第二上行授权信息用于指示传输待传输的上行数据所使用的传输资源(可以称为“上行传输资源”)。
需要说明的是，网络设备可以通过窄带物理上行控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)向终端发送第二上行授权信息，上述第二上行授权信息指示的用于传输待传输的上行数据的传输资源可以是NPUSCH对应的传输资源。
250，终端向网络设备发送待传输的上行数据。
具体地，终端在第二上行授权信息指示的传输资源上向网络设备发送待传输的上行数据。
从图2所示的流程图中可以看出，在NB-IoT中，为终端引入SR机制后，终端可以通过SR机制向网络设备请求上行传输资源，无需再通过发起随机接入过程向网络设备请求上行传输资源，一方面，节省了终端请求上行传输资源的时间。另一方面，避免了该终端在发起随机接入的过程中和其他终端发起的随机接入过程产生冲突，导致该终端通过随机接入请求上行传输资源失败。降低终端由于随机接入过程失败，而导致请求上行传输资源失败的可能性，有利于提高终端请求上行传输资源成功的可能性。
然而，在NB-IoT中，终端通常是一种低功耗低成本的终端设备，该终端的能力通常是受限的：
(1)终端不能同时进行上行数据和下行数据的传输。终端采用半双工的通信方式，待传输的数据可以在一个信号载体的两个方向上传输，但是不能同时传输，也就是说，终端在接收NPDSCH的同时没有剩余的带宽发送NPUSCH。
(2)终端在通过搜索空间(Search Space)检测NPDCCH的时候，不能够发送NPUSCH。
(3)终端在上行方向上采用单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)技术，所以不能同时向网络设备发送SR和NPUSCH。
通常为了使得终端在发送NPUSCH时，具有较低的峰值平均功率比(Peak-to-Average Power Ratio，PAPR)，并延长终端的电池的使用寿命，通常在上行方向上采用SC-FDMA技术。
也就是说，在NB-IoT中，为终端引入SR机制后，由于终端的能力有限，如果终端周期性的传输SR时，会存在终端发送SR和终端待执行的其他终端行为之间冲突的情况，例如，终端发送SR和终端检测搜索空间之间冲突，终端发送SR和终端接收NPDSCH之间冲突，终端发送SR和终端发送NPUSCH之间冲突等。
为了减少终端发送SR和终端待执行的其他终端行为之间的冲突，下文结合图3，详细描述本申请实施例的用于请求上行传输资源的方法。
图3是本申请实施例的用于请求上行传输资源的方法的示意性流程图。应理解，图3示出了通信方法的详细的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作，或者图3中各操作的变形。此外，图3中的各个步骤可以按照与图3呈现的不同顺序来执行，并且有可能并非要执行图3中的全部操作。下面具体描述图3所示的方法步骤。
310，终端确定向网络设备发送第一请求时存在冲突，其中，所述第一请求用于请求所述网络设备给所述终端调度上行传输资源。
需要说明的是，上述第一请求用于终端向网络设备请求上行传输资源，例如，可以是调度请求SR或缓存状态报告BSR。其中，SR携带在控制信令中传输，BSR可以携带在数据中传输。
可选地，作为一个实施例，所述终端确定向网络设备发送第一请求时存在冲突，包括：所述终端确定拟发送所述第一请求时，所述终端正在接收或发送所述终端的其他数据。
具体地，上述终端确定拟发送第一请求时，终端正在接收或发送终端的其他数据，还可以包括终端确定准备发送第一请求时，终端被网络设备调度进行该终端的其他数据的传输，也就是说，终端进行其他数据的传输在时间上与终端发送第一请求冲突。
上述终端确定拟发送第一请求时，终端正在接收或发送终端的其他数据，可以包括终端准备发送第一请求时，终端发送第一请求时的传输资源被调度准备用于传输该终端的其他数据；还可以包括终端准备发送第一请求时，终端发送第一请求时的传输资源被调度正在用于传输该终端的其他数据。也就是说，此时，传输第一请求的传输资源被该终端占用。
可选地，所述终端确定拟发送所述第一请求时，所述终端正在接收或发送所述终端的其他数据，包括：所述终端确定拟发送所述第一请求时，所述终端检测搜索空间，或者所述终端确定拟发送所述第一请求时，所述终端向所述网络设备发送窄带物理上行共享信道NPUSCH；或者所述终端确定拟发送所述第一请求时，所述终端接收所述网络设备发送的窄带物理下行共享信道NPDSCH；或者所述终端确定拟发送所述第一请求时，所述终端向所述网络设备发送随机接入信号。
具体地，上述搜索空间可以包括公共搜索空间和终端的专用搜索空间，其中，公共搜索空间是指所有终端都需要监测的空间，通常用来发送寻呼、随机接入响应(Random Access Response，RAR)、系统消息和终端的上行功率控制消息等。也可以说，将这些信息的调度信息映射到公共搜索空间，终端的专用搜索空间是指针对某个终端的信息，不需要所有终端监听。也可以说，将这些信息的调度信息映射至终端的专用搜索空间；所述专用搜索空间映射有至少一个终端设备的调度信息。多个终端设备的调度信息可以重叠使用该专用搜索空间中的资源。所述专用搜索空间可以包括多个控制信道元素 (Control Channel element)CCE，所述多个CCE用于承载所述至少一个终端设备的控制信息或调度信息，当有多个终端设备时，承载至少两个终端设备的控制信息或调度信息的CCE可以相同或不同。
上述向网络设备发送NPUSCH，可以指通过NPUSCH向网络设备发送上行信号(例如，上行数据)。
上述接收网络设备发送的NPDSCH，可以指通过NPDSCH接收网络设备发送下行信号(例如，下行数据)。
上述向网络设备发送随机接入信号，可以指终端通过窄带物理随机接入信道(Narrowband Physical Random Access Channel，NPRACH)向网络设备发送随机接入信号。
320，所述终端根据预设规则，调整所述第一请求的发送方式。
具体地，终端确定向网络设备发送第一请求存在冲突时，终端可以根据预设规则，调整第一请求的发送方式，以避免终端在发送第一请求时存在的冲突，上述预设规则可以指示第一请求的发送方式。
需要说明的是，上述第一请求的发送方式可以包括第一请求的编码方式，第一请求的发送时间，第一请求的传输资源等，本申请实施例对此不作具体限定。
可选地，预设规则可以指示第一请求的发送时间。
例如，上述预设规则可以通过为终端配置执行不同指令的优先级，以调整第一请求的发送时间。预设规则可以指示终端检测搜索空间的优先级高于终端发送第一请求的优先级，若终端确定检测搜索空间与终端向网络设备发送第一请求冲突，终端可以先检测搜索空间，再向网络设备发送第一请求；预设规则可以指示终端向网络设备发送NPUSCH的优先级高于终端发送第一请求的优先级，若终端确定发送NPUSCH与终端向网络设备发送第一请求冲突，终端可以先发送NPUSCH，再向网络设备发送第一请求；预设规则可以指示终端接收网络设备发送的NPDSCH的优先级高于终端发送第一请求的优先级，若终端确定接收NPDSCH与终端向网络设备发送第一请求冲突，终端可以先接收NPDSCH，再向网络设备发送第一请求；预设规则可以指示终端向网络设备发送随机接入信号的优先级高于终端发送第一请求的优先级，若终端确定发送随机接入信号与终端向网络设备发送第一请求冲突，终端可以先发送随机接入信号，再向网络设备发送第一请求。
在本申请实施例中，终端可以通过第一请求向网络设备请求上行传输资源，避免了现有技术中，终端只能通过发起随机接入流程向网络设备请求上行传输资源，以提高终端向网络设备请求上行传输资源的灵活性。
进一步地，终端通过第一请求向网络设备请求上行传输资源，在一定程度上减少了终端通过随机接入过程请求上行传输资源产生的时延，并且避免了终端由于发起随机接入过程失败，导致的请求上行传输资源失败，有利于提高终端请求上行传输资源的效率。
最后，终端基于预设规则调整第一请求的发送方式，以避免终端发送第一请求时存在的冲突。
可选地，若所述终端确定拟发送所述第一请求时，所述终端检测搜索空间，所述终端根据预设规则，调整所述第一请求的发送方式，包括：在第一时间段，所述终端检测所述搜索空间；在第二时间段，所述终端向所述网络设备发送所述第一请求，所述第一 时间段为所述第二时间段之前的时间段。
具体地，第一时间段为第二时间段之前的时间段，终端可以先检测搜索空间，在该搜索空间检测完成后，再向网络设备发送第一请求。也就是说，终端可以在搜索空间之后的用于传输第一请求的传输资源发送第一请求。
例如，如果终端向网络设备指示SR和终端检测公共搜索空间(Common search space，CSS)获取上行同步信息(Msg2)冲突，则终端检测CSS的优先级高于终端向网络设备指示SR，BSR可以在随机接入过程中的第三消息(Msg3)中发送。
可选地，终端可以选择在时域上位于搜索空间检测的传输资源之后，且离搜索空间结束时间段最近的用于传输第一请求的传输资源上，向网络设备发送第一请求。
终端选择离搜索空间结束时间段最近的用于传输第一请求的传输资源，作为传输第一请求的传输资源。在一定程度上，节约了终端通过第一请求向网络设备请求上行传输资源的时间。
可选地，所述第一时间段为所述第二时间段之前的时间段，所述终端检测所述搜索空间，包括下列情况中的任一种：所述终端在所述搜索空间内检测到下行授权DL Grant，所述终端在所述搜索空间内未检测到控制信息，所述终端在所述搜索空间内检测到上行授权UL Grant。
具体地，无论终端在搜索空间中是否检测到控制信息(例如，DL Grant或UL Grant)，终端都可以在搜索空间结束之后的传输资源上向网络设备发送第一请求。
可选地，作为一个实施例，所述在第一时间段，所述终端检测所述搜索空间，包括：所述终端在所述搜索空间内检测到下行授权DL Grant；所述在第二时间段，所述终端向所述网络设备发送所述第一请求，包括：在所述第二时间段，所述终端在第一传输资源上向所述网络设备发送ACK/NACK和所述SR，所述第一传输资源为所述DL Grant指示的用于传输所述ACK/NACK的传输资源。
具体地，终端可以在DL Grant指示的传输ACK/NACK的传输资源上传输第一请求。
需要说明的是，上述终端可以是支持单进程(例如，HARQ进程)的终端；还可以是支持双进程的终端，其中，支持双进程可以指终端可以并行在两个进程中进行数据的传输；还可以是支持多进程的终端，也就是说，下文描述的两个进程可以是终端支持的多个进程中的任意两个。下面以终端支持的两个进程为例，描述终端向网络设备发送第一请求与终端检测搜索空间冲突的情况下，本申请实施例的用于请求上行传输资源的方法。
可选地，作为一个实施例，若所述终端支持第一进程中下行数据的传输和第二进程中下行数据的传输，且第一DL Grant用于调度所述第一进程中的下行数据的传输，第二DL Grant用于调度所述第二进程中的下行数据的传输，所述在第一时间段，所述终端检测所述搜索空间，包括：在所述第一时间段，所述终端在所述搜索空间内检测到所述第一DL Grant和所述第二DL Grant；所述在第二时间段，所述终端向所述网络设备发送所述第一请求，包括：在所述第二时间段，所述终端在所述第二传输资源向所述网络设备发送ACK/NACK和所述第一请求，所述第二传输资源为所述第一DL Grant指示的用于传输所述第一进程中的所述ACK/NACK的传输资源；所述方法还包括：在所述第三时间段，所述终端在第三传输资源上向所述网络设备发送ACK/NACK和所述第一请求，所述第三传输资源为所述第二DL Grant指示的用于传输所述第二进程中的所述ACK/NACK 的传输资源，所述第三时间段为所述第一时间段之后的时间段。
具体地，终端在搜索空间内检测到用于调度两个进程的下行授权(第一DL Grant和第二DL Grant)，则终端可以分别在两个DL Grant指示的传输两个进程的ACK/NACK的传输资源上都发送第一请求。
终端在搜索空间检内测到用于调度两个进程的下行授权时，终端可以在两个DL Grant指示的传输两个进程的ACK/NACK的传输资源上都发送第一请求，以提高传输第一请求的可靠性。
可选地，作为一个实施例，若所述终端支持第一进程中下行数据的传输和第二进程中下行数据的传输，且第一DL Grant用于调度所述第一进程中的下行数据的传输，第二DL Grant用于调度所述第二进程中的下行数据的传输，所述在第一时间段，所述终端检测所述搜索空间，包括：在所述第一时间段，所述终端在所述搜索空间内检测到所述第一DL Grant和所述第二DL Grant；所述终端向所述网络设备发送所述第一请求，包括：所述终端在所述第一DL Grant指示的用于传输所述第一进程中的所述ACK/NACK的传输资源上，向所述网络设备发送ACK/NACK和所述第一请求。
具体地，若终端在搜索空间内检测到用于调度两个进程的DL Grant(第一DL Grant和第二DL Grant)，终端可以在上述两个进程中的任意一个进程(例如可以是上文中第一进程)中的ACK/NACK的传输资源上发送第一请求。
可选地，第一DL Grant指示的第一进程中的用于传输ACK/NACK的传输资源的时域位置在第二DL Grant指示的第二进程中的用于传输ACK/NACK的传输资源的时域位置之前，因此，终端可以在第一进程中的用于传输ACK/NACK的传输资源上发送第一请求。
通过选择离终端在搜索空间内检测下行授权后时间最近的传输ACK/NACK的传输资源，作为传输第一请求的传输资源，在一定程度上，节约了终端通过第一请求向网络设备请求上行传输资源的时间。
例如，图4是本申请实施例的用于请求上行传输资源的方法的示意图。从图4所示的方法中可以出，终端支持在第一进程中接收网络设备发送的NPDSCH，并且在第二进程中接收网络设备发送的NPDSCH。当终端在检测搜索空间时，同时检测到用于调度第一进程中NPDCH传输的第一DL Grant，以及用于调度第二进程中NPDCH传输的第二DL Grant时，终端可以根据第一DL Grant确定第一进程中用于向网络设备反馈ACK/NACK的传输资源，终端还可以根据第二DL Grant确定第二进程中用于向网络设备反馈ACK/NACK的传输资源，终端可以选择第一进程和第二进程中反馈ACK/NACK的传输资源靠前的传输资源，即图4所示的第一进程中用于反馈ACK/NACK的传输资源，作为终端发送SR的传输资源。
可选地，预先约定所述第一DL Grant指示的所述第一进程中的用于传输ACK/NACK的传输资源用于传输所述第一请求。
具体地，上述第一DL Grant调度的第一进程中的用于传输ACK/NACK的传输资源还可以是终端和网络设备预先约定的可以传输第一请求的传输资源，也就是说，只有在第一DL Grant调度的第一进程中传输ACK/NACK的传输资源上可以传输第一请求。
需要说明的是，上述终端和网络设备预先约定可以指网络设备和终端之间通过协议预先约定，还可以指网络设备和终端之间通过信令预先约定，本申请实施例对此不作具 体限定。
通过终端和网络设备预先约定可以传输第一请求的传输资源是第一进程中的用于传输ACK/NACK的传输资源，有利于减少传输第一请求引起的开销。

需要说明的是，对于支持第三进程中下行数据的传输和第四进程中下行数据的传输的终端而言，该终端在搜索空间中检测到第三进程和第四进程中任意一个进程的下行授权(可以是上文提到的第三DL Grant)，则该终端可以在该下行授权(第三DL Grant)指示的用于传输ACK/NACK的传输资源上发送第一请求。
可选地，预先约定所述第三DL Grant指示的所述第三进程中用于传输ACK/NACK的传输资源用于传输所述第一请求。

可选地，作为一个实施例，若所述终端支持第五进程中NPDSCH的接收，和第六进程中NPDSCH的接收，所述在第五时间段，所述终端接收所述网络设备发送的所述NPDSCH，包括：在所述第五时间段，所述终端接收所述网络设备发送的所述NPDSCH为在所述第五进程中接收的NPDSCH，所述在第六时间段，所述终端向所述网络设备发送所述第一请求，包括：在所述第六时间段，所述终端在第十传输资源上向所述网络设备发送ACK/NACK和所述第一请求，所述第十传输资源为传输用于指示所述终端是否接收到所述第五进程中传输的NPDSCH的所述ACK/NACK的传输资源。
可选地，作为一个实施例，预先约定用于指示所述终端是否接收到所述第五进程中传输的NPDSCH的所述ACK/NACK的传输资源用于传输所述第一请求。
具体地，上述第五进程还可以是终端和网络设备预先约定的可以传输第一请求的进 程，也就是说，只有在第五进程中的传输ACK/NACK的传输资源上可以传输第一请求。
需要说明的是，上述终端和网络设备预先约定可以指网络设备和终端之间通过协议预先约定，还可以指网络设备和终端之间通过信令预选约定，本申请实施例对此不作具体限定。
通过终端和网络设备预先约定可以传输第一请求的传输资源是第五进程中的用于传输ACK/NACK的传输资源，有利于减少传输第一请求引起的开销。
可选地，作为一个实施例，若所述终端支持第五进程中NPDSCH的接收，第六进程中NPDSCH的接收，所述在第五时间段，所述终端接收所述网络设备发送的所述NPDSCH，包括：在所述第五时间段，所述终端接收所述网络设备发送的所述NPDSCH为在所述第六进程中接收的NPDSCH；所述在第六时间段，所述终端向所述网络设备发送所述第一请求，包括：所述终端在传输ACK/NACK的目标传输资源上，向所述网络设备发送所述ACK/NACK和所述第一请求，所述ACK/NACK的目标传输资源为所述第五进程中用于指示所述终端是否接收到NPDSCH的ACK/NACK的传输资源的时域位置与所述第六进程中用于指示所述终端是否接收到NPDSCH的ACK/NACK的传输资源的时域位置最早的传输资源。
具体地，终端可以在第五进程中用于ACK/NACK的传输资源和第六进程中用于ACK/NACK的传输资源中选择离终端准备发送第一请求的时间段最近的传输资源作为目标传输资源，在传输ACK/NACK的同时传输第一请求。
终端可以在第五进程中用于ACK/NACK的传输资源和第六进程中用于ACK/NACK的传输资源中选择离终端准备发送第一请求的时间段最近的传输资源作为目标传输资源，在传输ACK/NACK的同时传输第一请求，在一定程度上，节约了终端通过第一请求向网络设备请求上行传输资源的时间。
可选地，所述ACK/NACK和所述第一请求经过
Figure PCTCN2017083353-appb-000002
进行调制。
具体地，在ACK/NACK的传输资源上传输ACK/NACK和第一请求时，ACK/NACK和第一请求经过
Figure PCTCN2017083353-appb-000003
进行调制。
需要说明的是，终端可以通过第一请求机制向网络设备请求上行传输资源(例如，SR机制使能)之后，终端可以采用QPSK的调制方式发送ACK/NACK，此时，基站可以用QPSK的方式接收终端发送的ACK/NACK。避免了SR使能之后，终端需要发送SR和ACK/NACK时用QPSK的调制方式，只发送ACK/NACK时采用BPSK的调制方式，使得网络设备需要同时使用BPSK和QPSK的方式进行盲检，降低网络设备的检测复杂度。
上文中主要描述了终端接收NPDSCH与终端向网络设备指示第一请求冲突的情况下，本申请实施例的用于请求上行传输资源的方法，下文主要描述终端发起随机接入过程与终端向网络设备指示第一请求冲突的情况下，本申请实施例的用于请求上行传输资源的方法。
可选地，作为一个实施例，所述终端确定拟发送所述第一请求时，所述终端向所述网络设备发送随机接入信号，所述终端根据预设规则，调整所述第一请求的发送方式，包括：在第七时间段，所述终端向所述网络设备发送所述随机接入信号；在第八时间段，所述终端向所述网络设备发送所述第一请求，所述第七时间段为所述第八时间段之前的时间段，或所述第七时间段和所述第八时间段为同一时间段。
可选地，所述终端确定拟发送所述第一请求时，所述终端向所述网络设备发送随机接入信号，所述终端根据预设规则，调整所述第一请求的发送方式，包括：所述终端向所述网络设备发送所述随机接入信号，所述随机信号携带所述第一请求。
可选地，所述终端向所述网络设备发送所述随机接入信号，所述随机信号携带所述第一请求，包括：通过码分复用的方式传输所述随机信号和所述第一请求。
可选地，作为一个实施例，所述终端确定拟发送所述第一请求时，所述终端向所述网络设备发送随机接入信号，所述终端根据预设规则，调整所述第一请求的发送方式，包括：所述终端在第一区域或第二区域中的传输资源上向所述网络设备发送所述随机接入信号，其中，在所述第一区域中的传输资源上发送所述随机接入信号用于指示所述终端向所述网络设备发送所述第一请求，在所述第二区域中的传输资源上发送所述随机接入信号用于指示所述终端不向所述网络设备发送所述第一请求。
具体地，上述在第一区域中的传输资源上发送所述随机接入信号用于指示所述终端向所述网络设备发送所述第一请求，可以指终端有待传输的上行数据需要传输；上述在第二区域中的传输资源上发送所述随机接入信号用于指示所述终端向所述网络设备发送所述第一请求，可以指终端没有待传输的上行数据需要传输。
终端通过在不同的区域上向网络设备发送随机接入信号，隐式的指示终端是否有待传输的上行数据需要传输，在一定程度上，可以减少终端发送第一请求产生的信令开销。
为了减少终端发送第一请求和终端待执行的其他终端行为之间的冲突，除了上文结合图3描述的本申请实施例的用于请求上行传输资源的方法，下文结合图6详细描述本申请另一实施例的用于请求上行传输资源的方法。
图6是本申请另一实施例的用于请求上行传输资源的方法的示意性流程图。图6所示的方法包括：
610，终端确定用于传输调度请求SR的专用的传输资源。
具体地，上述专用的传输资源可以是专门用于传输SR的传输资源，换句话说，SR可以不在用于传输其他信息的传输资源上传输。例如，SR可以不在传输ACK/NACK的传输资源上与ACK/NACK一起传输。
620，所述终端在所述专用的传输资源上向网络设备发送所述SR。
具体地，终端在专用的传输资源上向网络设备发送SR，以向网络设备请求传输待传输的上行数据的上行传输资源。
在本申请实施例中，终端在传输SR的专用的传输资源上，向网络设备发送SR以请求上行传输资源，避免了现有技术中，终端只能通过发起随机接入流程向网络设备请求上行传输资源，以提高终端向网络设备请求上行传输资源的灵活性。
进一步地，终端通过向网络设备发送SR请求上行传输资源，在一定程度上减少了终端通过随机接入过程请求上行传输资源产生的时延，并且避免了终端由于发起随机接入过程失败，导致的请求上行传输资源失败，有利于提高终端请求上行传输资源的效率。
最后，终端在传输SR的专用的传输资源上，向网络设备发送SR，避免了终端向网络设备发送SR和终端待执行的其他终端行为之间产生冲突。
可选地，作为一个实施例，所述方法还包括：所述终端根据待传输的数据量确定目标信道编码方式；所述终端对所述SR的以所述目标信道编码方式进行信道编码。
可选地，作为一个实施例，所述目标信道编码方式包括正交编码方式，所述终端对 所述SR以所述目标信道编码方式进行信道编码，包括：所述终端对所述SR以所述正交编码的方式进行信道编码。
具体地，所述终端对所述SR以所述正交编码的方式进行信道编码，可以指终端对SR以正交码的方式进行传输。
可选地，作为一个实施例，所述终端根据待传输的数据量确定目标信道编码方式，包括：所述终端确定所述待传输的数据量所在的数据量范围；所述终端根据所述待传输的数据量所在的数据量范围，以及数据量范围与信道编码方式的映射关系确定所述目标信道编码方式。
通过SR的信道编码方式指示终端待传输的数据的数据量的数据量范围，使得终端在通过SR指示网络设备终端有待传输的上行数据的同时，还指示了待传输的上行数据的数据量的数据量范围，在一定程度上，简化了终端请求上行传输资源的流程。
可选地，作为一个实施例，所述数据量范围与信道编码方式的映射关系中不同的数据量范围对应的信道编码方式不同。
具体地，不同的数据量范围可以对应不同的信道编码方式，终端可以通过向网络设备发送以目标信道编码方式进行信道编码后的SR，在向网络设备指示终端有待传输的上行数据需要传输的同时还可以通过目标信道编码方式向网络设备指示终端待传输的数据的数据量所在的数据量范围。
需要说明的是，网络设备可以对SR进行盲检，以确定对SR进行信道编码的目标信道编码方式。
下面以BSR作为待传输的上行数据的数据量为例，通过表1至表10分别列出了10种数据量范围与信道编码方式的映射关系。需要说明的是，通过不同的信道编码方式生成的SR，在传输性能(例如，覆盖范围、错检率、漏检率等)方面的优劣性不同，可以根据信号的传输需求选择不同类信道编码方式。
还应理解，表1至表10仅示出了部分可能的信道编码方式与BSR范围的映射关系，本申请实施例对此不作具体限定。
