数据发送和指示数据发送的方法及设备
相关申请的交叉引用
本申请要求在2019年1月11日提交中国专利局、申请号为201910028831.2、发明名称为“一种数据发送和指示数据发送的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种数据发送和指示数据发送的方法及设备。
背景技术
在下一代无线(New radio，NR)系统中，网络侧会预先配置一些上行(Uplink，UL)资源，方便一些对传输数据时延要求高的业务(比如，高可靠低时延通信(Ultra Reliable Low Latency Communications，URLLC)或业务格式比较规则的业务(比如基于IP的语音传输(Voice over Internet Protocol，VoIP)业务))在这些配置的UL资源上传输。
在终端设备(User Equipment，UE)发送数据时，需要利用网络侧为UE配置授权的资源，利用上行调度请求(Scheduling Request，SR)机制动态授权的资源发送数据，且在UE利用上述资源发送数据时，需要优先发送URLLC数据。但是UE利用配置授权资源和动态授权资源发送数据时，存在以下场景，UE发送URLLC数据时延增加的问题：
1)配置授权与动态授权资源碰撞导致URLLC数据时延增加
如图1所示，当预配置授权资源与动态授权调度的资源相重叠或碰撞时，优先利用动态授权资源发送动态调度数据。但是，动态授权中承载的是增强移动宽带(Enhance Mobile Broadband，eMBB)的数据，即对传输时延要求不高的数据，而在预配置授权中承载的是URLLC数据，即对传输时延要求较高的数据(需要很低的传输时延)。这时候动态授权数据的发送使得预配置授权数据无法发送，导致对传输时延要求较高业务的URLLC数据的时延增加。
2)SR发送资源与上下行共享信道(如物理上行共享信道(physical uplink shared channel，PUSCH))资源相碰撞，导致URLLC数据的发送延迟
由于eMBB业务或增强型机器类型通信(enhanced machine type of communication，eMTC)业务对时延要求较低，所以网络侧会配置较长的PUSCH持续长度。而URLLC对时延要求较高，所以网络侧会给配置较短的PUSCH持续长度。
存在这样一种情况，即对应URLLC逻辑信道的数据到达，触发了缓存状态(Buffer Status Report，BSR)报告，而此时没有UL授权，那么会触发URLLC逻辑信道对应的SR。在触发SR后，UE被分配了UL授权，此时UE可以在对应的UL授权，即图2中的PUSCH上发送BSR。UE会取消URLLC逻辑信道对应的SR，而在UL授权上发送携带URLLC数据量大小的BSR。
但是由于此时的PUSCH是针对非URLLC业务分配的，因此网络的处理时延较长，从而导致URLLC的发送延迟问题。
3)MAC CE复用优先级问题导致URLLC数据被延迟
如图3所示，由于BSR的优先级要高于任何来自数据逻辑信道的优先级，那么当BSR包含的数据量是非URLLC业务时，而发送的UL授权大小又不足以发送URLLC数据时，会导致URLLC数据被延迟。
4)混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈，导致URLLC数据时延增加问题
如图4所示，HARQ反馈与PUSCH资源相碰撞，或PUSCH资源不够用时，会优先发送PUSCH数据，但是当HARQ反馈为URLLC数据的反馈，这样会造成URLLC数据反馈时延增加，进而增加URLLC传输时延。
综上所述，终端设备利用配置授权资源和动态授权资源发送数据时很多下场景下存在高可靠低时延数据发送时延增加的问题，即终端设备在传输或接收不同类型的数据，发生资源碰撞冲突时，不能优先发送对资源或时延等有特殊要求的数据。

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份实施例，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。
本申请实施例描述的应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着新应用场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
其中，上述5G NR系统主要支持以下三类业务：
1)增强型宽带通信(enhanced Mobile Broadband,eMBB)；
2)大量机器类型通信(massive Machine Type Communications，mMTC)；
3)高可靠低时延(Ultra-Reliable and Low Latency Communications，URLLC)。
其中，URLLC主要是指高可靠、低时延业务。主要应用场景包括：工业自动化、智能城市、增强现实(Augmented Reality，AR)或虚拟现实(Virtual Reality，VR)等。其中低时延要求低至0.5ms，高可靠性丢包率低至1E-6。
目前UE利用配置授权资源和动态授权资源发送数据时，以下场景下，存在UE不能优先发送URLLC数据的问题：

3)MAC CE复用优先级问题导致URLLC数据被延迟发送；
4)HARQ反馈与PUSCH资源相碰撞，或PUSCH资源不够用时，会优先发送PUSCH 数据，进而增加URLLC传输时延。
为解决针对上述场景中类似URLLC数据被延迟传输的问题，本申请实施例提供一种数据发送和指示数据发送的方法及设备。
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。
针对上述场景，下面结合说明书附图对本申请实施例做进一步详细描述。
如图5所示，本实施例提供一种适用于终端设备UE的数据发送的方法，具体包括以下步骤：
步骤501，接收网络侧指示的与第一信道相关的至少一个优先级门限，并根据上述至少一个优先级门限确定第一优先级门限Pth。
作为一种可选的实施方式，网络侧根据以下任一一个内容或任意多个内容指示上述先级门限：终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、核心网配置信息。
上述第一优先级门限Pth与第一信道相关且用于第一信道上数据可能会被延迟的场景，不同的延迟场景对应不同的第一优先级门限Pth。
步骤502，当上述第一信道和第二信道重叠时，根据上述第一信道的第一优先级P1和第一优先级门限Pth，确定是否传输或获取第一数据。
其中，上述第一信道用于传输或获取第一数据，上述第二信道用于传输或获取第二数据。
上述第一数据和第二数据是不同的数据，上述第一数据为有特殊要求需要被优先传输的数据。
上述方法中，通过上述第一信道的第一优先级P1和第一优先级门限Pth决定是否优先传输第一数据，避免了传输数据的过程中，用来传输或获取第一数据的第一信道和第二信道冲突时，有特定需求的第一数据被延迟的现象，保证了能优先传输或获取第一数据。
在一种可能的实现方式中，上述第一数据为高可靠低时延数据或高可靠低时延数据的反馈。
在上述步骤501的一种可能的实现方式中，终端设备接收网络侧指示的以下任一一个或多个优先级门限：配置授权优先级门限、SR传输优先级门限、HARQ反馈优先级门限、MAC CE(media access control element，媒体接入控制控制单元)传输优先级门限。
根据第一信道和第二信道发生重叠对应的场景和上述优先级门限，确定第一优先级门限Pth，确定当前场景下第一信道对应的第一优先级门限。
当上述第一数据为高可靠低时延数据或高可靠低时延数据的反馈信息时，上述第一信道传输或获取第一数据，包括操作中的以下任一一个或多个组合：
利用第一信道传输或获取配置授权的数据；
利用第一信道传输或获取SR数据；
利用第一信道接收HARQ反馈；
利用上行授权信道传输高可靠低时延数据。
在上述步骤502的一种可能的实现方式中，当上述第一数据为高可靠低时延数据或可 靠低时延数据的反馈信息时，上述第一信道和第二信道重叠的场景可以但不局限于包括以下任一一个或多个组合：
1)配置授权资源与动态授权资源碰撞；
2)SR发送资源与PUSCH资源相碰撞；
3)HARQ反馈占用资源与PUSCH资源相碰撞，或PUSCH资源不够用时(此时默认的数据传输方式会优先发送PUSCH数据时)；
4)MAC CE复用优先级问题导致URLLC数据被延迟发送。
在上述步骤502的一种可能的实现方式中，根据上述第一优先级P1和第一优先级门限Pth，确定是否传输或获取第一数据，包括以下几种情况：
情况1：当P1>Pth时，传输或获取第一数据。其中，P1>Pth表示第一信道的第一优先级P1高于第一优先级门限Pth。
情况2：当P1>Pth且P1>P2时，传输或获取第一数据，上述P2为第二数据对应的所有逻辑信道优先级的最大值。其中，P1>P2表示第一信道的第一优先级P1高于第二数据对应的所有逻辑信道优先级中的最高优先级。
情况3：当P1>Pth且P1≤P2时，传输或获取第二数据。其中，P1≤P2表示第一信道的第一优先级P1低于或等于第二数据对应的所有逻辑信道优先级中的最高优先级。
上述第一优先级门限Pth为配置授权优先级门限时，第二数据为复用到动态授权的数据。
基于相同的发明构思，如图6所示，本实施例还提供一种适用于网络侧的指示数据发送的方法，具体包括：
步骤601，确定与第一信道相关的至少一个优先级门限；
步骤602，将上述确定的至少一个优先级门限指示给终端设备，以使上述终端设备确定上述第一信道和第二信道重叠时，根据上述第一信道的第一优先级P1和所述至少一个优先级门限中的第一优先级门限Pth，确定是否传输或获取第一数据。
其中，上述第一信道用于传输或获取第一数据，上述第二信道用于传输或获取第二数据。
上述第一数据为高可靠低时延数据或高可靠低时延数据的反馈。
作为一种可选的实施方式，网络侧可以但不局限于根据以下任一一个或多个内容，确定与第一信道相关的至少一个优先级门限：终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、核心网配置信息。
上述第一优先级门限Pth为：配置授权优先级门限；或SR传输优先级门限；或HARQ反馈优先级门限；或MAC CE传输优先级门限。
本实施例提供一种数据发送的方法，适用于配置授权资源与动态授权资源碰撞的场景。
在下一代无线NR中，网络侧会预先配置一些上行UL资源，方便一些对传输数据时延要求高的业务(比如，高可靠低时延通信URLLC或业务格式比较规则的业务(比如VoIP))在这些配置的UL资源上传输。
目前调度UL资源的调度方式有配置授权类型1和配置授权类型2两种，上述两种调度方式的相同点是基站会预先给终端设备UE分配周期性的资源位置，UE会按照基站分配的资源位置发送数据。
上述两种调度方式的区别点在于：
配置授权类型1通过无限资源控制(Radio Resource Control，RRC)信令配置资源位置、调制编码(Modulation Coding Scheme，MCS)方式、无线资源块(Radio Block，RB)大小、HARQ个数，分配资源位置的周期，且在RRC配置后即生效，不需要物理层激活、去激活的过程；
配置授权类型2，通过RRC信令配置资源位置、HARQ个数、分配资源位置的周期，但不会配置MCS方式、RB大小；且需要物理层发送下行控制信息(Downlink control information，DCI)对资源进行激活和去激活操作，上述配置才生效。
上述配置授权类型1和配置授权类型2中，数据的发送过程分别如图7和图8所示。其中，图7表示配置授权类型1的特征是：网络侧通过RRC配置了资源后，资源即可使用。图8中，在网络侧通过RRC配置之后，需要网络侧再激活资源，UE才能使用配置授权。图7和图8的区别在于是否需要物理层激活过程。
如前所述，预配置授权资源可能会与动态授权调度的资源相重叠或碰撞，针对该场景，本实施例中的第一信道是指复用URLLC数据的配置授权信道，第二信道是指复用动态调度数据对应的逻辑信道，第一数据为复用到配置授权的数据，第二数据为动态授权的数据。
在实施中，网络侧根据终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、核心网配置信息配置相应的配置授权优先级门限PriorityThreshold_cg并指示给终端设备，终端设备接收网络侧指示的配置授权优先级门限，在发生上述冲突场景时确定第一优先级门限Pth为配置授权优先级门限，并根据第一信道的第一优先级P1和第一优先级门限Pth，确定是否传输或获取第一数据。
可选地，确定第一信道中的逻辑信道优先级的最大值为P1，第二信道中逻辑信道优先级的最大值为P2。
当P1>PriorityThreshold_cg时，发送预配置授权的URLLC数据；或者，当P1≤PriorityThreshold_cg且P1>P2时，发送预配置授权的URLLC数据；或者，当P1≤PriorityThreshold_cg且P1≤P2时，发送动态调度的数据。
当UE执行动态调度数据重传时，上述P2表示复用到传输块(Transport Block，TB)执行重传的第二信道的逻辑信道优先级的最大值；当UE执行动态调度数据新传时，则表示复用到动态授权上的第二信道中逻辑信道优先级得的最大值，上述方法的实现效果如图9所示。这里的P1是指配置授权的逻辑信道优先级的最高值。图9中，P1的优先级大于PriorityThreshold_cg，所以优先传输了配置授权，这里停止了动态调度的传输。
本实施例提供一种数据发送的方法，适用于SR发送资源与PUSCH资源相碰撞的场景。
在UE进行数据传输时，若UE没有上行数据要传输，网络侧并不需要为该UE分配上行资源，否则会造成资源的浪费，为避免不必要的资源浪费，UE需要告诉网络侧自己是否有上行数据需要传输，以便网络侧决定是否给UE分配上行资源，为此NR提供了一个上行调度请求SR机制。
UE通过SR信息告诉网络侧是否需要上行资源以便用于上行共享通信(Uplink-Shared Channel，UL-SCH)传输，但UE并不会告诉网络侧需要发送的上行数据的数量(上述需要发送的上行数据的数量通过BSR报告)。网络侧收到UE发送的SR后，根据网络侧的实现方式给UE分配一定量的上行资源，通常是至少为UE分配足够发送BSR的资源。
网络侧不知道UE发送上行数据的时间，因此，网络侧需要在已经分配的资源上检测是否有SR信息上报。
MAC实体可以被配置0个、1个或多个SR配置；一个SR配置包括多个带宽片段(Bandwidth part，BWP)和对应的小区上的一系列物理层上行控制信道(Physical Uplink Control Channel，PUCCH)资源，对于一个逻辑信道，每个BWP上最多只能配置一个PUCCH资源。
上述每一个SR配置对应1个或多个逻辑信道，每个逻辑信道可以对应0个或1个SR，这些由RRC信令配置。其中，触发BSR的SR为等待pending SR。UE因为无上行PUSCH资源，故而发送SR，因此UE只能在物理层上行控制信道(Physical Uplink Control Channel，PUCCH)上发送SR。
网络侧可以为每个UE分配一个专用的SR资源用于发送SR，该资源时周期性的，每间隔固定数量子帧/时隙/符号分配一个上述SR资源。
如图10，为SR传输的一个例子，其中，UE在数据到达后，触发了一个SR，并在下一个最近的SR资源上发送了SR，随后，UE收到了UL授权，并在UL授权指示的PUSCH(UL-SCH)上发送数据，上述数据一般是指包含BSR的数据包。
但是在上述传输SR时，会出现SR发送资源与PUSCH资源(可以是发送BSR的资源)相碰撞的情况，进而导致SR被延时发送。
本实施例中，第一信道为SR的SR配置所对应的逻辑信道，第二信道为上行授权PUSCH信道；第一数据为URLLC类型的SR，第二数据为PUSCH数据。
为了解决上述问题，在本实施例中，网络侧根据终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、网络侧配置相应的SR传输优先级门限PriorityThreshold_SR并指示给终端设备；终端设备接收网络侧指示的SR传输优先级门限，在发生上述冲突场景时确定第一优先级门限Pth为SR传输优先级门限，根据第一信道的第一优先级P1和第一优先级门限Pth，确定是否传输或获取SR(第一数据)。
本实施例中，将第一信道中的逻辑信道优先级的最大值记为P1，将第二信道中逻辑信道优先级的最大值记为P2。
当P1>PriorityThreshold_SR时，在物理层发送URLLC数据的SR；或者，当P1≤PriorityThreshold_SR1且P1>P2时，在物理层发送URLLC数据的SR；或者，当P1≤PriorityThreshold_SR1且P1≤P2时，发送PUSCH数据。
如图11所示为采用本实施例上述数据发送方法对应的SR与PUSCH数据传输时序图。
本实施例提供一种数据发送的方法，适用于HARQ反馈与PUSCH资源相碰撞，或PUSCH资源不够用的场景。
在终端设备传输HARQ反馈，出现HARQ反馈与PUSCH资源相碰撞，或PUSCH资源不够用时，会优先发送PUSCH数据，进而增加URLLC传输时延的情况。
本实施例中第一信道为传输或获取HARQ反馈对应的逻辑信道，第二信道为上行授权PUSCH的逻辑信道；第一数据为HARQ反馈，第二数据为PUSCH数据。
为了解决上述问题，在本实施例的方案中，网络侧根据终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、核心网配置信息配置相应的HARQ反馈优先级门限PriorityThreshold_HARQ_feedback并指示给终端设备；终端设备接收网络侧发送的HARQ反馈优先级门限，在发生上述冲突场景时，确定第一优先级门限Pth为HARQ反馈优先级门限，并根据第一信道的第一优先级P1和第一优先级门限Pth，确定是否传输或获取HARQ反馈。
本实施例中，确定当前第一信道对应的优先级为P1，记第二信道中逻辑信道优先级的最大值为P2。
当P1>PriorityThreshold_HARQ_feedback时，发送URLLC数据的HARQ反馈；或者，当P1≤PriorityThreshold_HARQ_feedback且P1>P2时，发送PUSCH数据；或者，当P1≤PriorityThreshold_HARQ_feedback且P1≤P2时，发送动态调度的数据。
上述方法中，物理上行共享信道PUSCH数据与URLLC数据的混合自动重传请求HARQ反馈碰撞时，根据优先级门限的比较结果决定是否优先传输URLLC数据的HARQ反馈，使URLLC数据的HARQ反馈及时传输。
本实施例提供一种数据发送的方法，适用于MAC CE复用优先级问题导致URLLC数据被延迟发送的场景。
MAC层逻辑信道复用优先级顺序如下所示：
1)C-RNTI MAC CE或者是从UL公共控制信道中获取的数据；
2)配置授权确认MAC CE；
3)除了填充BSR以外的，其他BSR，比如常规BSR(regular BSR)，周期BSR；
4)PHR；
5)除了从UL公共控制信道以外其他数据信道获取的数据；
6)推荐比特率请求MAC CE；
7)Padding BSR。
BSR的优先级要高于任何来自数据逻辑信道的优先级，那么当BSR包含的数据量是非URLLC业务时，而发送的UL授权大小又不足以发送URLLC数据时，会导致URLLC数据被延迟。
本实施例中，第一信道为上行授权对应的逻辑信道，第二信道为MAC CE复用的逻辑信道；第一数据为上行授权数据，第二数据为MAC CE复用的数据。
为了解决上述问题，在本实施例的方案中，网络侧根据终端设备传输业务特征、网络侧信道资源状态、终端设备信道状态、核心网配置信息配置相应的MAC CE传输优先级门限PriorityThreshold_MACCE并指示给终端设备，终端设备接收网络侧指示的MAC CE传输优先级门限，并在发生上述冲突时确定第一优先级门限Pth为MAC CE传输优先级门限，并根据第一信道的第一优先级P1和第一优先级门限Pth，确定是否传输或获取上行授权数据。
本实施例中，将复用到第一信道中逻辑信道优先级的最大值作为P1，将MAC CE复用的第二信道对应的优先级为P2。
当P2>PriorityThreshold_MAC CE时，复用MAC CE；或者，当P2≤PriorityThreshold_MAC CE且P1>P2时，优先复用MAC CE；或者，当P2≤PriorityThreshold_MAC CE且P1≤P2时，优先复用上行授权数据逻辑信道上的数据。

上述处理器用于接收网络侧指示的与第一信道相关的至少一个优先级门限，所述至少一个优先级门限中包括第一优先级门限；
