相关申请的交叉引用
本申请基于申请号为201710313330.X、申请日为2017年5月5日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本发明涉及无线通信技术领域，尤其涉及的是一种半持续调度的混合自动重传请求的传输方法及装置。
背景技术
在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)无线接入网技术中，引入了一种半持续调度(SPS，Semi Persistent Scheduling)的调度方法，在SPS技术中，接入网网络侧网元(例如长期演进(LTE，Long Term Evolution)的演进的节点B(eNB，evolved Node B)，第五代移动通信技术(5G，fifth-generation，)/下一代无线系统(NR，New Radio)中的gNB)通过无线资源控制(RRC，Radio Resource Control)消息为用户设备(UE，User Equipment)配置SPS间隔(interval)，以及用于SPS控制的SPS小区无线网络临时标识(C-RNTI，Cell-Radio Network Temporary Identifier)。接入网网络侧网元在物理下行控制信道(PDCCH，Physical Downlink Control Channel)发送使用SPS C-RNTI加扰的下行控制信息(DCI，Downlink Control Information)，用来控制SPS调度的激活、去激活以及混合自动重传请求(HARQ，Hybrid Automatic Repeat Request)的重传。
相关技术中，如果上述SPS C-RNTI加扰的DCI中的信元新数据指示(NDI，New Data Indicator)设置为0，且该DCI中信元release(释放)设置为0，则UE初始化或重新初始化SPS调度资源，此时，SPS调度资源为：以SPS间隔(SPS interval)为周期重复配置的所述DCI指示的下行指配(DL assignment)或上行授权(UL grant)。所述的上行SPS调度资源又称为配置的上行授权(configured uplink grant)，所述的下行SPS调度资源又称为配置的下行指配(configured downlink assignment)。以图1所示上行SPS资源为例，配置的上行授权以SPS间隔重复出现，也即当SPS间隔是10个子帧时，相邻的配置的上行授权之间间隔10个子帧。
如果上述SPS C-RNTI加扰的DCI中的信元NDI设置为0，且该DCI 中信元release(释放)设置为1，则UE释放配置的SPS资源，针对上行SPS资源，UE释放配置的上行授权(configured uplink grant)，针对下行SPS，UE释放配置的下行指配(downlink assignment)。
对上行SPS资源，UE通过免调度的方式使用所述配置的上行授权，即UE在上述配置的上行授权资源中直接发送上行数据，而不需要接入网网络侧网元另行发送上行授权信息。对下行SPS，UE直接在配置的下行指配资源中接收下行物理下行共享信道(PDSCH，Physical Downlink Shared Channel)信道。
对上行SPS资源，在HARQ为异步重传模式(asynchronous HARQ)时,如果上述的DCI中信元NDI设置为1，则该DCI为一个HARQ重传指示，该DCI中的进程标识(PID，Process ID)指示了需要进行HARQ重传的HARQ进程标识，以及用于HARQ重传的上行授权信息。UE接收到该指示HARQ重传的DCI，在所述的上行授权指示的上行资源中，重传所述HARQ进程标识所对应的HARQ进程的缓冲区(buffer)中的数据传输块(TB，Transport Block)。
对下行SPS资源，在HARQ为asynchronous HARQ时，如果上述的DCI中信元NDI指示为1，则该DCI指示一个下行HARQ重传，此时DCI中信元PID指示了需要进行重传的HARQ进程标识。
在现有3GPP技术中，一个小区或载波只有一个HARQ实体(HARQ entity)，即在小区或载波上的HARQ进程均归属于同一个HARQ实体管理，不同的上行HARQ进程或下行HARQ进程通过HARQ实体内唯一的HARQ标识进行区别。
在相关技术中，如果HARQ为异步重传模式，一种确定上行HARQ进程标识或下行HARQ进程标识的方法如下：
对于上行HARQ：
UE和接入网网络侧网元通过下述公式(1-1)确定使用配置的上行授权的上行HARQ进程的标识HARQ_PID：
Figure PCTCN2018085700-appb-000001
在上述公式中，T是SPS间隔；m是上行HARQ进程数量；
Figure PCTCN2018085700-appb-000002
是向下取整运算符号；MOD是取模运算符号；t＝n_SFN*M+n_Sub；n_SFN为上行HARQ进程使用配置的上行授权对应的系统帧号，M为一个无线帧中包含的无线子帧的数量，n_Sub为上行HARQ进程使用的配置的上行授权对应的无线子帧号。
对于下行HARQ：
UE和接入网网络侧网元确定使用配置的下行指配的下行HARQ进程的标识的方式与上行HARQ类似，也采用上述公式(1-1)；其中，T是SPS间隔，m是下行HARQ进程数量；t＝n_SFN*M+n_Sub；n_SFN为下行HARQ 进程使用的配置的下行指配对应的系统帧号，M为一个无线帧中包含的无线子帧的数量，n_Sub为下行HARQ进程使用的配置的下行指配对应的无线子帧号。
图2为相关技术中计算上行SPS HARQ进程ID的一个例子，在该例子中，配置的上行SPS进程数为2，SPS间隔为10个无线子帧，第一个配置的上行授权的起始子帧是子帧2，则在系统帧号(SFN，System Frame Number)为0的无线帧的无线子帧2的配置的上行授权上进行上行传输时，上行SPS HARQ进程ID为0，在SFN为1的无线帧的无线子帧2的配置的上行授权上进行上行传输时，上行SPS HARQ进程ID为1，在SFN为2的无线帧的无线子帧2的配置的上行授权上进行上行传输时，上行SPS HARQ进程ID为0，以此类推。
在5G/NR接入技术或LTE中，如果一个UE在一个小区或载波中配置多套SPS配置(configuration)，不同的SPS配置的间隔、上行授权资源或下行指配资源不同，且其HARQ为异步重传模式时，如果使用现有技术中的方法计算使用不同SPS配置的不同HARQ进程的标识，将会出现HARQ进程标识的冲突，即不同的HARQ进程的标识相同。

示例1
下面通过一个示例说明接入网网络侧网元为用户设备配置上行HARQ进程的标识偏移，根据所述上行HARQ进程的标识偏移确定所述上行HARQ进程的标识，进行上行HARQ的传输。
在接入网网络侧网元为UE配置多个SPS配置(SPS configuration)时，每个SPS配置至少包含上行SPS间隔和上行SPS进程数量。对某个配置的上行授权(configured uplink grant)，与之关联(associated)的上行HARQ进程的标识通过如下方式确定：
HARQ_PID＝Offset+{[floor(CURRENT_TTI/T_SPS)]modulo(n_P)}      (2-1)
在上述公式(2-1)中，Offset是上行授权所属的SPS配置所对应的上行HARQ进程标识偏移值(简称偏移)；floor为取整数运算(下取整)；modulo为取余数运算；T_SPS为所述SPS配置的上行SPS间隔；n_P为所述SPS配置的上行HAQR进程数量；其中，所述的HARQ进程标识偏移offset通 过RRC消息发送到UE。
如果所述SPS配置的无线资源(配置的上行授权)的时域单位为无线子帧(subframe)，则：CURRENT_TTI＝n_SFN*T+n_Sub；(2-2)
在上述公式(2-2)中，n_SFN为配置的上行授权的系统帧号(system frame number，SFN)，n_Sub为配置的上行授权的无线子帧号,T为无线帧包含的无线子帧的个数。
如果所述SPS配置的无线资源(配置的上行授权)的时域单位为时隙(slot)，则：
CURRENT_TTI＝(n_SFN*T+n_Sub)*N_slot+n_slot；     (2-3)
在上述公式(2-3)中，N_slot是一个子帧包含的时隙数量，n_slot是配置的上行授权的时隙序号。
在一种可选的实施方式中，接入网网络侧网元在配置上述SPS进程标识偏移值offset时，根据UE在一个载波或小区上配置的多个SPS配置的上行SPS进程数量进行配置的。
例如，对某个UE，在某个载波中配置3套SPS配置，其中SPS配置1配置的上行SPS HARQ进程数为N1，SPS配置2配置的上行SPS HARQ进程数为N2，SPS配置3的上行SPS HARQ进程数为N3。则接入网网络侧网元为SPS配置1配置的offset为M1，为SPS配置2配置的offset为M2＝M1+N1，为SPS配置3配置offset为M3＝M2+N2。
在确定了上行HARQ进程标识后，进一步的通过如下方法进行上行HARQ的传输：如图7所示，接入网网络侧网元在某个SPS配置对应的上行授权上接收到UE的上行传输，如果接入网网络侧网元需要UE重新发送所述的上行传输，则向UE发送用于重传的上行授权(UL grant)，并在相应的PDCCH信令DCI中指示需要重传的上行HARQ进程的标识。
UE接收到所述用于重传的上行授权根据相应的DCI指示的上行HARQ进程标识，可知道哪个HARQ进程需要重传。并根据所述用于重传的上行授权重新发送所述的上行传输。
示例2
下面通过一个示例说明接入网网络侧网元和用户设备按照约定的方式确定上行HARQ进程的标识偏移，根据所述上行HARQ进程的标识偏移确定所述上行HARQ进程的标识，进行上行HARQ的传输。
对某个配置的上行授权(configured uplink grant)，与之关联(associated)的上行HARQ进程的标识通过如下方式确定：
HARQ_PID＝Offset+{[floor(CURRENT_TTI/T_SPS)]modulo(n_P)}     (2-1)
在上述公式(2-1)中，Offset是上行授权所属的SPS配置所对应的上行HARQ进程标识偏移值(简称偏移)；floor为取整数运算(下取整)；modulo为取余数运算；T_SPS为所述SPS配置的上行SPS间隔；n_P为所述SPS配 置的上行HAQR进程数量；
如果所述SPS配置的无线资源(配置的上行授权)的时域单位为无线子帧(subframe)，则：CURRENT_TTI＝n_SFN*T+n_Sub；(2-2)
在上述公式(2-2)中，n_SFN为配置的上行授权的系统帧号(system frame number，SFN)，n_Sub为配置的上行授权的无线子帧号，T为无线帧包含的无线子帧的个数。
如果所述SPS配置的无线资源(配置的上行授权)的时域单位为时隙(slot)，则：
CURRENT_TTI＝(n_SFN*T+n_Sub)*N_slot+n_slot；(2-3)
在上述公式(2-3)中，N_slot是一个子帧包含的时隙数量，n_slot是配置的上行授权的时隙序号。
上述公式(2-1)中的offset可以通过如下方法确定：
第一步：确定所述SPS配置在用户设备的各种SPS配置中的排序位置，比如采用以下任意一种方式确定SPS配置的顺序：1)根据SPS配置在RRC配置消息中出现的顺序进行排序；2)根据SPS配置所使用无线资源的时域单位，或TTI长度(TTI duration)的大小进行排序；3)根据SPS配置第一次激活的时间顺序进行排序；4)根据配置消息中指定的SPS配置的序号进行排序；
第二步：根据所述SPS配置的排序位置确定该种SPS配置对应的HARQ进程的标识偏移，比如：确定某个SPS配置的上行SPS进程标识偏移为在排序处理后位于该SPS配置之前的所有SPS配置的上行SPS进程数之和，再加上排序在第一位的SPS配置的上行SPS进程数(比如，N0)，所述N0的值可以为0，或者通过RRC消息配置为一个正整数。
例如，为某个UE，在小区A中配置3套SPS配置，每个SPS配置对应的上行SPS进程数分别为N1，N2，N3。假设SPS配置的排序结果从前往后依次是：SPS配置1，SPS配置3，SPS配置2，则：SPS配置1的上行SPS HARQ进程标识偏移offset1＝N0；SPS配置3的上行SPS HARQ进程标识偏移offset3＝N0+N1；SPS配置2的上行SPS HARQ进程标识偏移offset2＝N0+N1+N3。
接入网网络侧网元在某个SPS配置对应的上行授权上接收到UE的上行传输，如果接入网网络侧网元需要UE重新发送所述的上行传输，则向UE发送用于重传的上行授权(UL grant)，并在相应的PDCCH信令DCI中指示需要重传的上行HARQ进程的标识。
UE接收到所述用于重传的上行授权根据相应的DCI指示的上行HARQ进程标识，可知道哪个HARQ进程需要重传。并根据所述用于重传的上行授权重新发送所述的上行传输。
示例3
下面通过一个示例说明接入网网络侧网元为用户设备配置下行HARQ 进程的标识偏移，根据所述下行HARQ进程的标识偏移确定所述下行HARQ进程的标识，进行下行HARQ的传输。
在接入网网络侧网元为UE配置多个SPS配置(SPS configuration)时，每个SPS配置至少包含下行SPS间隔和下行SPS进程数量。
对某个配置的下行指配(configured downlink assignment)，与之关联(associated)的下行HARQ进程的标识HARQ_PID通过如下方式确定：
HARQ_PID＝Offset+{[floor(CURRENT_TTI/T_SPS)]modulo(n_P)}      (2-1)
在上述公式(2-1)中，Offset是配置的下行指配所属的SPS配置所对应的下行HARQ进程标识偏移值(简称偏移)；floor为取整数运算(下取整)；modulo为取余数运算；T_SPS为所述SPS配置的下行SPS间隔；n_P为所述SPS配置的下行HAQR进程数量；
其中，所述的HARQ进程标识偏移offset通过RRC消息发送到UE。
如果所述SPS配置的无线资源(配置的下行指配)的时域单位为无线子帧(subframe)，则：CURRENT_TTI＝n_SFN*T+n_Sub；(2-2)
在上述公式(2-2)中，n_SFN为配置的下行指配的系统帧号(SFN，System Frame Number)，n_Sub为配置的下行指配的无线子帧号，T为一个系统帧包含的无线子帧的个数。
如果所述SPS配置的无线资源(上行授权)的时域单位为时隙(slot)，则：CURRENT_TTI＝(n_SFN*T+n_Sub)*N_slot+n_slot；(2-3)
在上述公式(2-3)中，N_slot是一个子帧包含的时隙数量，n_slot是配置的下行指配的时隙序号。
在一种可选的实施方式中，接入网网络侧网元在配置上述SPS进程标识偏移值offset时，根据UE在一个载波或小区上配置的多个SPS配置的下行SPS进程数量进行配置的。
例如，对某个UE，在某个载波中配置3套SPS配置，其中SPS配置1配置的下行SPS HARQ进程数为N1，SPS配置2配置的下行SPS HARQ进程数为N2，SPS配置3的下行SPS HARQ进程数为N3。则接入网网络侧网元为SPS配置1配置的offset为M1，为SPS配置2配置的offset为M2＝M1+N1，为SPS配置3配置offset为M3＝M2+N2。
接入网网络侧网元与用户设备之间进行下行HARQ传输：如图8所示，接入网网络侧网元通过某个SPS配置对应的下行指配发送下行传输。如果UE反馈了NACK，接入网网络侧网元进一步重新发送所述的下行传输，并在相应的PDCCH DCI中指示重传所对应的下行HARQ进程标识。UE接收到上述的DCI，从DCI中指示的HARQ进程标识可知此次下行传输所对应的HARQ进程。
示例4
下面通过一个示例说明接入网网络侧网元和用户设备按照约定的方式 确定下行HARQ进程的标识偏移，根据所述下行HARQ进程的标识偏移确定所述下行HARQ进程的标识，进行下行HARQ的传输。
对某个配置的下行指配(configured downlink assignment)，与之关联(associated)的下行HARQ进程的标识通过如下方式确定：
HARQ_PID＝Offset+{[floor(CURRENT_TTI/T_SPS)]modulo(n_P)}   (2-1)
在上述公式(2-1)中，Offset是配置的下行指配所属的SPS配置所对应的下行HARQ进程标识偏移值(简称偏移)；floor为取整数运算(下取整)；modulo为取余数运算；T_SPS为所述SPS配置的下行SPS间隔；n_P为所述SPS配置的下行HAQR进程数量；
如果所述SPS配置的无线资源(配置的下行指配)的时域单位为无线子帧(subframe)，则：CURRENT_TTI＝n_SFN*T+n_Sub；(2-2)
在上述公式(2-2)中，n_SFN为配置的下行指配的SFN，n_Sub为配置的下行指配的无线子帧号，T为一个系统帧包含的无线子帧的个数。
如果所述SPS配置的无线资源(配置的上行授权)的时域单位为时隙(slot)，则：CURRENT_TTI＝(n_SFN*T+n_Sub)*N_slot+n_slot；(2-3)
在上述公式(2-3)中，N_slot是一个子帧包含的时隙数量，n_slot是配置的下行指配的时隙序号。
上述公式(2-1)中的offset可以通过如下方法确定：
第一步：确定所述SPS配置在用户设备的各种SPS配置中的排序位置，比如采用以下任意一种方式确定SPS配置的顺序：1)根据SPS配置在RRC配置消息中出现的顺序进行排序；2)根据SPS配置所使用无线资源的时域单位，或TTI长度(TTI duration)的大小进行排序；3)根据SPS配置第一次激活的时间顺序进行排序；4)根据配置消息中指定的SPS配置的序号进行排序；
第二步：根据所述SPS配置的排序位置确定该种SPS配置对应的HARQ进程的标识偏移，比如：确定某个SPS配置的下行SPS进程标识偏移为在排序处理后位于该SPS配置之前的所有SPS配置的下行SPS进程数之和，再加上排序在第一位的SPS配置的下行SPS进程数(比如，N0)，所述N0的值可以为0，或者通过RRC消息配置为一个正整数。
例如，为某个UE，在小区A中配置3套SPS配置，每个SPS配置对应的下行SPS进程数分别为N1，N2，N3。假设SPS配置的排序结果从前往后依次是：SPS配置1，SPS配置3，SPS配置2，则：SPS配置1的下行SPS HARQ进程标识偏移offset1＝N0；SPS配置3的下行SPS HARQ进程标识偏移offset 3＝N0+N1；SPS配置2的下行SPS HARQ进程标识偏移offset 2＝N0+N1+N3。
接入网网络侧网元通过某个SPS配置对应的下行指配发送下行传输。如果UE反馈了NACK，接入网网络侧网元进一步重新发送所述的下行传 输，并在相应的PDCCH DCI中指示重传所对应的下行HARQ进程标识。UE接收到上述的DCI，从DCI中指示的HARQ进程标识可知此次下行传输所对应的HARQ进程。
本发明实施例提供的方法为UE配置多个SPS configuration的场景提供了接入网网络侧网元和UE确定使用SPS配置的无线资源的HARQ进程的标识的方法，避免了不同HARQ进程之间的标识冲突，使得异步HARQ传输和重传得以实现。
