Description
本发明涉及通信技术领域,特别涉及一种传输方法、传输装置、网络设备及用户设备。
长期演进(Long Term Evolution,LTE)系统中,上行常规数据传输是基于动态调度的。对于处于连接态并且上行同步的用户设备(User Equipment,UE)来说,如果有上行数据需要发送,UE需要向基站在物理上行控制信道(Physical Uplink Control Channel,PUCCH)信道发送上行调度请求(Scheduling Request,SR),基站在物理下行控制信道(Physical Downlink Control Channel,PDCCH)信道发送上行调度授权(UL-Grant)为UE分配PUSCH资源。
但是,随着UE传输需求的增多,PUCCH资源和PUSCH资源受限。尤其对于物联网或多UE实时游戏业务等较小数据包且要求低时延的传输场景,传统动态调度的方式不仅会造成信令开销大,且调度过程繁琐;而现有的半静态调度(Semi Persistent Scheduling,SPS)或预调度的资源分配方式,当调度的竞争资源上存在至少两个UE时,也无法避免冲突问题,从而造成资源浪费,传输时延增大。

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。
鉴于现有技术在上行数据传输过程中,调度UE信令开销较大,调度时延较长,且当大量UE需要传输上行数据时,PUCCH资源和PUSCH资源等传输资源受限的问题,本申请中提出一种方案,基站为UE配置资源请求参数,并通知UE可以使用的发送资源请求信息的PUSCH资源,其中,基站可以为UE分配任意一个与所述UE同时调度的其他UE用于发送数据的PUSCH资源,当UE需要发送数据时,先根据基站配置的资源请求参数,在基站分配的用于发送资源请求信息的PUSCH资源上,向基站发送资源请求信息,并且在基站为其分配的用于发送数据的PUSCH资源上发送数据,这样,本申请中,将用于UE发送资源请求信息的资源扩展到任意PUSCH资源上,扩大了UE发送资源请求信息的可用资源,并且基站在接收到UE发送的资源请求信息后,当判断有其他UE也所述UE请求相同的资源时,能机动的为所述UE分配与所述其他UE不同的用于发送数据的PUSCH资源,可以有效避免多个UE使用共同PUSCH资源时的冲突问题。总之,本申请中提供的方案能够有效缓解上行传输过程中传输资源受限的问题,提高资源使用效率,提升系统容量。
本申请可以适用于LTE系统,尤其适用于处理大量的、具有低时延要求
的、小数据包传输的场景。当然本申请的方案也可以应用于5G或其他网络。本申请应用的系统架构的一种示例如图1所示,系统10包括基站11和UE12。基站11用于配置UE12所用的资源请求参数以及PUSCH资源等。UE12用于根据基站11的配置发送资源请求,以及传输上行数据。
以下将结合具体实施例对本申请提供的一种传输方法、传输装置、网络设备及用户设备进行详细说明。
实施例一、
参阅图2所示,本申请中实施例一提供的传输方法流程如下所述。其中,实施例一以基站调度第一UE为例进行说明,且本申请中实施例一提供的方法适用于任意调度场景。
例如,一种可能的调度场景为基站已经为第一UE分配了SPS资源,且所述SPS资源可以是所述第一UE与其他UE共同使用的竞争资源。假设与所述第一UE共同使用竞争用的SPS资源的UE称为竞争UE。
步骤201:基站为第一UE配置资源请求参数,并将所述资源请求参数发送给所述第一UE。
其中,基站向所述第一UE发送PDCCH信息,并且基站指明发送的PDCCH信息为申请资源指示信息,所述申请资源指示信息中包含资源请求参数,用于指示所述第一UE根据资源请求参数发送资源请求信息;
所述资源请求参数包括循环移位值、时频资源位置、资源请求周期、正交覆盖码(Orthogonal Cover Code,OCC)中的一种或多种。
所述循环移位值用于当所述第一UE与其他UE共同占用PUSCH资源时,将所述第一UE与其他UE的信道估计结果在时域上进行区分。
所述时频资源位置用于指示所述第一UE发送资源请求信息时占用的时频资源位置,其中,较佳的一种方式是,基站为第一UE配置:发送资源请求信息时占用PUSCH资源的一个导频符号。
基站在调度所述第一UE时,也可能向非竞争UE发送调度信息。
步骤202:所述第一UE接收基站配置的所述资源请求参数。
步骤203:基站为所述第一UE分配第一PUSCH资源,所述第一PUSCH资源用于所述第一UE发送资源请求信息。
具体地,所述第一PUSCH资源的导频符号用于所述第一UE发送资源请求信息。
若基站已经为所述第一UE分配了竞争用的SPS资源,则基站为所述第一UE分配的用于发送资源请求信息的第一PUSCH资源可以是所述SPS资源,也可以是非竞争UE使用的PUSCH资源。
其中,基站可以采用但不限于以下两种方式向所述第一UE分配第一PUSCH资源。
第一种方式:
基站向所述第一UE发送UL-Grant消息,为便于描述,将这里的UL-Grant消息称为第一UL-Grant消息;所述第一UL-Grant消息中包含为所述第一UE分配的第一PUSCH资源的信息。
第二种方式:
基站向所述第一UE通知第二UE的PUSCH调度信息,所述第二UE的PUSCH调度信息中包含基站为所述第二UE分配的用于发送数据的第三PUSCH资源的信息,并指示所述第一UE,将所述第三PUSCH资源作为用于所述第一UE发送资源请求信息的所述第一PUSCH资源。
如步骤201中所述,基站在向所述第一UE发送包含资源请求参数的调度信息的同时,也可能调度非竞争UE,为方便描述,将这里的非竞争UE称为第二UE。
那么,在基站向所述第一UE分配第一PUSCH资源时,可以向所述第一UE发送所述第二UE所用的用于搜索PDCCH信息的无线网络临时标识(Radio Network Tempory Identity,RNTI)的值,用于所述第一UE根据所述第二UE所用的RNTI获取所述第二UE的PUSCH调度信息,即,所述第一UE可以获得所述第二UE的第三PUSCH的时频资源位置、OCC码、循环移位值等调度信息。其中,RNTI可以但不限于C-RNTI,Semi-Persistent
Scheduling C-RNTI,Temporary C-RNTI。当然,基站也可以通过向所述第一UE发送的资源请求参数,直接将所述第二UE的第三PUSCH的时频资源位置通知给所述第一UE。
较佳的,基站通知所述第一UE占用所述第二UE的第三PUSCH资源的导频符号发送资源请求信息。
并且,基站为所述第一UE和所述第二UE配置不同的循环移位值,用于所述第一UE和所述第二UE通过不同的循环移位值在不同的时间占用所述第三PUSCH资源。
步骤204:所述第一UE确定基站分配的第一PUSCH资源,并在所述第一PUSCH资源上,根据所述资源请求参数向基站发送资源请求信息。
具体地,所述第一UE在所述第一PUSCH资源的导频符号上,根据所述资源请求参数向基站发送资源请求信息。
所述第一UE根据接收到的基站发送的第一上行调度授权UL-Grant消息,确定基站分配的所述第一PUSCH资源;或者,
所述第一UE根据基站通知的第二UE的PUSCH调度信息,将所述第二UE的PUSCH调度信息中包含的基站为所述第二UE分配的用于发送数据的第三PUSCH资源,确定为基站分配的第一PUSCH资源。具体地,所述第一UE根据接收到的基站发送的所述第二UE所用的无线网络临时标识RNTI,获取所述第二UE的PUSCH调度信息
若所述第一UE需要发送数据,则所述第一UE在发送数据之前,在基站分配的第一PUSCH资源上,根据所述资源请求参数,向基站发送资源请求信息。
若所述第一UE将所述第三PUSCH资源确定为所述第一PUSCH资源,则所述第一UE在所述第三PUSCH资源上,根据基站为其配置的循环移位值,向基站发送资源请求信息。
步骤205:基站在所述第一PUSCH资源上,检测到所述第一UE根据所述资源请求参数发送的资源请求信息,则为所述第一UE分配用于发送数据的
第二PUSCH资源。
若所述第一UE在所述第二UE的PUSCH资源的导频符号上发送的资源请求信息,则基站根据为所述第一UE和所述第二UE分配的不同的循环移位值,检测所述第一UE发送的资源请求信息。当检测到所述第一UE发送的资源请求信息之后,确定所述第一UE需要发送数据,则为所述第一UE分配用于发送数据的第二PUSCH资源。这里,为所述第一UE分配第二PUSCH资源可以包括但不限于以下几种情况。
1、若基站预先为所述第一UE和至少一个第三UE分配了共同的上行SPS资源、且检测到所述第一UE和所述至少一个第三UE分别发送的资源请求信息,确定所述第一UE和所述至少一个第三UE均需要在所述共同的上行SPS资源上发送数据,则为所述第一UE分配一个与所述至少一个第三UE使用的PUSCH资源不同的PUSCH资源,作为所述第一UE用于发送数据的所述第二PUSCH资源。
上述上行SPS资源即竞争资源,上述第三UE也就是与所述第一UE共同使用竞争资源的竞争UE,基站已经为所述第一UE和至少一个第三UE分配了竞争资源,若基站检测到所述第一UE和所述至少一个第三UE均发送了资源请求信息,则确定所述第一UE和所述至少一个第三UE均需要在所述竞争资源上发送数据,显然,若不处理,则所述第一UE和所述至少一个第三UE就会发生冲突,导致竞争资源的浪费。本申请中,在这种情况下,为所述第一UE与所述至少一个第三UE分配不同的PUSCH资源,包括:向所述至少一个第三UE发送专用调度,使得所述至少一个第三UE在专用调度资源上发送数据,这样,所述第一UE可以继续使用竞争资源发送数据;或者,向所述第一UE发送专用调度,使得所述第一UE在专用调度资源上发送数据。总之,基站为所述第一UE分配与所述至少一个第三UE不同的PUSCH资源,有效避免所述第一UE与所述至少一个第三UE在发送数据时产生冲突的问题。
2、若基站预先为所述第一UE和至少一个第三UE分配了共同的上行SPS资源、且检测到所述第一UE和所述至少一个第三UE分别发送的资源请求信
息,确定所述第一UE和所述至少一个第三UE均需要在所述共同的上行SPS资源上发送数据,则指示所述第一UE和所述至少一个第三UE分别占用所述上行SPS资源的时间资源,所述基站将所述第一UE在指示的时间资源上占用的所述上行SPS作为为所述第一UE分配的用于发送数据的第二PUSCH资源。
除上述第1种调度方法外,本申请中提供了第2种避免竞争UE产生冲突的方法。基本思想是,所述第一UE和所述至少一个第三UE均使用竞争资源发送数据,但是占用所述竞争资源上的不同时间资源,例如占用不同的数据符号,这样,可以完全避免多个竞争UE的冲突问题。
具体地,基站向所述第一UE发送第二UL-Grant消息,在所述第二UL-Grant消息中携带指示信息,所述指示信息用于指示所述第一UE占用所述上行SPS的时间资源;当然,基站同时向所述至少一个第三UE发送UL-Grant消息来指示占用所述上行SPS资源的时间资源,第一UE与所述至少一个第三UE占用的时间资源显然不同。
其中,基站可以在所述第二UL-Grant消息中的可复用比特中,根据所述可复用比特与所述上行SPS资源的时间资源的映射关系,在为所述第一UE分配的时间资源对应的比特中标记指示信息。
3、若基站预先为所述第一UE和至少一个第三UE分配了共同的上行SPS资源、且只检测到所述第一UE发送的资源请求信息,而未检测到所述至少一个第三UE发送的资源请求信息,则表明所述第一UE在下一个发送子帧上不存在竞争用户,那么基站可以不向所述第一UE发送重新分配第二PUSCH资源的信息,所述第一UE会在下一个发送子帧上占用所述上行SPS资源发送数据。
步骤206:所述第一UE确定基站分配的用于发送数据的第二PUSCH资源,并在所述第二PUSCH资源上发送数据。
具体的,所述第一UE根据接收到的基站发送的指令,确定所述指令中包含第二PUSCH资源的信息;并
根据所述指令,在所述第二PUSCH资源上发送数据。
其中,若所述第一UE已知基站为其分配的用于发送数据的上行SPS资源,则所述第一UE接收基站发送的第二UL-Grant消息,根据所述第二UL-Grant消息中的可复用的比特,与所述上行SPS资源上的时间资源的映射关系,以及所述可复用的比特中标记的指示信息,确定基站为所述第一UE分配的在所述上行SPS资源上所占用的时间资源;并在所述上行SPS资源上所占用的时间资源上发送数据。
若所述第一UE已知基站为其分配的用于发送数据的上行SPS资源,在向基站发送资源请求信息后,未接收到基站分配的用于发送数据的第二PUSCH资源的信息,则在所述上行SPS资源上发送数据。
下面结合具体的应用场景对本申请实施例一提供的方法作进一步详细说明。以下“用户”在概念上与“UE”等同。
参阅图3所示,假设基站已为包括用户M的至少一个用户分配了竞争用的SPS资源,SPS周期为T。假设用户M在子帧n中的SPS资源称为第一SPS资源,在子帧n+T中的SPS资源称为第二SPS资源。
基站在子帧n-T,向用户M和用户A发送调度信息,其中用户A为任意一个非竞争用户,即不与用户M竞争所述SPS资源。
基站在用户A的PDCCH信息中携带用户A将在子帧n中使用的PUSCH资源信息,且基站为用户A配置的PUSCH资源的参数为{频域位置:RB10到RB20;OCC=NULL;循环移位值=0}。
基站在用户M的PDCCH信息中,指示用户M该PDCCH信息为申请资源指示信息,且在该PDCCH信息中携带资源请求参数,至少包括以下任意一项:OCC码、循环移位值,所用的时频资源位置。可选的,用户A的RNTI也可以包含在该PDCCH信息中。例如,基站在用户M的PDCCH中携带的资源请求参数为{OCC=NULL;循环移位值=6;所用的导频符号为10}。
这样,用户M可以根据用户A的RNTI去网络侧获取到用户A的PUSCH资源信息,得知用户A的PUSCH频域资源为RB10到RB20,则用户M在子
帧n上发送资源请求信息时的资源请求参数为{频域位置:RB10到RB20;OCC=NULL;循环移位值=6;所用的导频符号为10},也就是说,用户M在子帧n的导频符号10上,在用户A的PUSCH频域资源RB10到RB20上,按照自身的循环移位值通过码分的方式发送一个参考信号,作为资源请求信息。
同理,基站在子帧n-T+1上,也可以向用户M和用户B发送调度信息,其中用户B为任意一个非竞争用户。用户M可以在子帧n+1上,在用户B的PUSCH资源上,按照自身的循环移位值通过码分的方式发送一个参考信号,作为资源请求信息。相同之处不再赘述。
基站在子帧n上,在用户A的PUSCH资源上,检测用户M是否发送了资源请求信息,具体地,根据用户A和用户M不同的循环移位值进行检测,若检测到了用户M发送了资源请求信息,则确定用户M将要在子帧n+T上,在为其分配的后续第一个SPS资源上(也就是第二SPS资源上)发送数据。
基站若同时检测到与用户A共同使用竞争资源的其他用户也发送了资源请求消息,请求在第二SPS资源上发送数据,则为用户A和与其竞争的其他用户分配不同的传输资源,具体分配方法如上述实施例一种描述,在此不再赘述。
通过本申请提供的上述实施例一,基站为第一UE分配用于发送资源请求信息的第一PUSCH资源,并在接收到第一UE的资源请求信息后,为第一UE分配用于发送数据的第二PUSCH资源,这样,使得第一UE可以占用为任意UE分配的PUSCH资源发送资源请求信息,有效缓解了PUCCH容量受限的问题,并且可以实现更多的UE发送资源请求;同时,还可以解决基于竞争的半静态调度的过程中,UE产生冲突的问题,从而实现更加有效的利用PUSCH资源,减少了上行传输时延;总之,可以提高上行传输过程中资源使用效率,增大系统容量。
实施例二、
鉴于现有的基于竞争的上行传输方案中,多个UE使用竞争资源时会产生
冲突,基站无法检测出任何一个UE的信息,导致传输资源浪费且传输时延增大的问题,基于上述实施例一同一种发明构思,本申请实施例二将上述实施例一的方法应用于具体的竞争场景中,对上述实施例一提供的方法作更进一步详细的说明。主要思想是,提前判断是否会在竞争资源上产生冲突,若判定会产生冲突,则为冲突的UE分配不同的传输资源,可以完全避免在竞争资源上产生冲突,以及避免了由冲突导致的资源浪费和增大时延等一系列问题。
以下将结合附图对本申请实施例二提供的传输方法进行详细说明。
参阅图4所示,本申请提供的传输方法的具体流程如下。
步骤400:基站为N个UE分配相同的物理上行共享信道PUSCH资源,其中,N≥2,N为正整数。
本申请实施例二中,基站通过SPS的方式,周期地为若干个UE分配相同的PUSCH资源,这里假设为N个,该相同的PUSCH资源即N个UE传输上行数据所用的竞争资源。也就是,N个UE均可以在该相同的PUSCH资源上发送上行数据。
基站在与调度的各个UE建立RRC连接过程中,通过RRC消息完成SPS配置,所述SPS配置包括SPS周期;通过PDCCH发送SPS激活消息,以激活SPS配置,在所述SPS激活消息中指示为UE分配的PUSCH资源位置。为了将N个UE配置在相同的PUSCH资源上,可以为N个UE中的每个UE分配单独的PDCCH资源,在所述单独的PDCCH资源中指示相同的PUSCH资源;或者,也可以为N个UE配置一个组RNTI,即CB-RNTI,N个UE基于同一个CB-RNTI搜索PDCCH消息,以此来获得相同的PUSCH资源。
基于SPS周期,基站分配间隔性的PUSCH资源,在一个子帧上,可能只有一个UE将要发送数据,也可能没有UE发送数据,也可能有至少两个UE将要发送数据,当有至少两个UE将要发送数据时,在这个子帧上就会产生冲突,本申请实施例二中,在这个子帧到来之前,需要判断将要在这个子帧上发送数据的UE的数目。
基于这个构思,本申请实施例二中将子帧的一个符号用作指示符号,所
述指示符号用于UE发送参考信号,所述参考信号用于通知基站UE需要在下一个子帧上发送数据,所述下一个子帧与发送参考信号的子帧之间的间隔为SPS周期。
需要说明的是,本申请实施例二中,SPS周期可能是固定周期,也可能是非固定周期。
优选地,指示符号为一个导频符号。
参阅图5所示为PUSCH资源周期性分配示意图以及指示符号分配示意图,以常规CP下的子帧结构为例,一个子帧有14个符号,其中时隙slot0中符号3和slot1中符号10为导频符号,其余符号为数据符号。本申请中,选取其中一个导频符号作为指示符号,例如,选取符号10作为指示符号,用于UE发送指示需要在下一个子帧发送数据的参考信号;符号3仍用作导频符号,用于信道估计。
符号10作为指示符号时可以单独发送,也就是,UE在当前子帧的数据符号上不发送数据时,也可以在指示符号上单独发送参考信号,当有多个UE在当前子帧上同时发送参考信号时,为了检测出多个参考信号,本申请实施例二中,为N个UE中的每一个UE分配了循环移位值。
基站在调度各个UE的过程中,需要分别向N个UE中的各个UE通知相应的循环移位值,以及,通知所述指示符号在子帧上的位置。
具体地,基站通过RRC消息分别向各个UE通知相应的循环移位值,和指示符号在子帧上的位置。其中,基站可以直接通知各个UE相应的循环移位值,也可以,按照3GPP TS36.211协议5.5.2.1.1-1表格所示通知UE一个索引值,通过索引值获得最终使用的循环移位值;基站通知指示符号在子帧上的位置,可以通知UE指示符号所在的时隙位置,slot0或slot1,也可以用符号索引表示,例如常规CP中,通知UE指示符号为符号3或符号10,扩展CP中,通知UE指示符号为符号2或符号8。
步骤401:UE确定用于发送数据的PUSCH资源,其中,在所述PUSCH资源上复用至少两个UE。
具体地,所述UE为基站调度的N个UE中的任意一个UE,根据步骤400中基站的分配,UE确定用于发送上行数据的PUSCH资源,所述PUSCH资源即N个UE发送数据的竞争资源。并且,根据步骤400中基站的分配,UE确定指示符号在子帧中的位置以及UE对应的循环移位值。
步骤402:UE在第一子帧的指示符号上向基站发送参考信号,所述参考信号用于向基站通知所述UE需要在所述第一子帧之后的第二子帧上发送数据。
以PUSCH资源上,相邻的两个发送子帧为例进行说明,分别称作第一子帧和第二子帧,第一子帧和第二子帧之间的间隔为SPS周期,SPS周期为固定周期或非固定周期。所述指示符号用于UE发送通知基站UE需要在第二子帧上发送数据的参考信号。所述指示符号为第一子帧上的一个导频符号。
具体地,UE根据其对应的循环移位值,在第一子帧的导频符号上,向基站发送参考信号。
步骤403:基站在所述PUSCH资源的第一子帧上,依据所述N个UE分别对应的循环移位值,对所述第一子帧上的指示符号进行检测,得到所述N个UE分别对应的检测结果。
具体地,基站在第一子帧上的一个导频符号的位置上,分别根据N个UE对应的循环移位值进行检测,获得N个UE分别对应的信道估计结果。
基站为N个UE分配了不通的循环移位值后,在进行信道估计时,不同的循环移位值代表了信道估计结果在时域上的时间偏移,所以N个UE的信道估计结果在时域上互不重叠。如图6所示为基站获得信道估计结果的示意图。图6中,以N=4为例。基站为4个UE:UE1、UE2、UE3、UE4分配了相同的参考信号的传输资源和不同的循环移位值,假设UE1、UE2、UE3、UE4的循环移位值分别为0、3、6、9,当4个UE都在第一子帧的指示符号上发送参考信号时,由于4个UE的循环移位值不同,所以4个UE的信道估计结果在时域上显示不同,也就是信道的功率时延谱是散开的。基站在各个UE的循环移位值对应的检测窗口,进行信道估计结果的能量检测,能够分别
得到各个UE的检测结果,即各个UE是否在指示符号上发送的参考信号。
步骤404:基站根据所述检测结果,确定有n个UE在所述第一子帧上发送了参考信号,在所述第二子帧到来之前,分别为所述n个UE分配不同的传输资源,2≤n≤N,n为正整数。
基站根据各个UE的循环移位值对应的检测窗口的信道估计结果,确定有哪些UE在第一子帧的指示符号上发送了参考信号,假设有n个,n为正整数,当然当n=1时,即在第一子帧的指示符号上只有一个UE发送的参考信号,表明在第一子帧之后的第二子帧上将会只有一个UE发送数据,也就是说不会产生冲突,本申请实施例二中,若n=1,则基站不作后续处理。针对2≤n≤N这种情况,即在第一子帧的指示符号上有至少两个UE发送了参考信号,表明第一子帧之后的第二子帧上将会有至少两个UE发送数据,也就是说会产生冲突,本申请实施例二中,基站会在第二子帧到来之前,分别为n个UE分配不同的传输资源。
具体分配不同的传输资源的方法可以但不限于包括以下两种。
第一种、
在第二子帧到来之前,在n个UE中,选择n-1个UE,分别为所述n-1个UE分配与所述PUSCH资源不同的其他PUSCH资源。
在第一种分配方法中,基站在n个UE中选择一个UE继续使用预先分配的相同的PUSCH资源(也就是竞争资源)传输数据,而为其余的n-1个UE发送专用调度,例如向其余n-1个UE发送UL-Grant,在UL-Grant中指示UE专用的PUSCH资源位置,所述专用的PUSCH资源位置与所述相同的PUSCH资源位置不同。
第二种、
在第二子帧到来之前,分别向n个UE发送指示信息,所述指示信息用于指示UE在所述PUSCH资源上,在第二子帧上发送数据时占用的数据符号;
其中,1个UE至少占用1个数据符号,所述n个UE占用的总的数据符号的数目不大于第二子帧可用的数据符号的总数。
基站在确定在第二子帧上将会有n个UE发送冲突后,也可以不分配其他的PUSCH资源,而是在所述相同的PUSCH资源上,在第二子帧内将时域的符号资源细分给各个用户使用,这样虽然各UE仍在同一个子帧内传输数据,但由于在时域上分开了,因此也就避免了冲突问题。
具体地,基站将第二子帧内可用的数据符号划分给n个UE使用,可以平均分配给各个UE,也可以根据UE的测量上报,根据UE的传输需求分配给各个UE使用。
基站向所述n个UE中的任意一个UE发送指示信息,可以但不限于采用以下方式:
基站向任意一个UE发送上行调度授权UL-Grant消息,在所述UL-Grant消息中的可复用的比特中,根据所述可复用的比特与所述第二子帧的数据符号的映射关系,选择为所述任意一个UE分配的数据符号对应的比特,并在所选择的比特中标记指示信息。
例如,UL-Grant消息结构为:跳频标识(Hopping flag)占用1bit、资源块分配指示(Fixed size resource block assignment)占用10bits、调制解调方案指示(Truncated modulation and coding scheme)占用4bits、功控指示(TPC command for scheduled PUSCH)占用3bits、上行延迟发送指示(UL delay)占用1bit、信道状态信息请求指示(CSI request)占用1bit;
由于在SPS场景中,PUSCH资源的资源块位置对于UE来说是已知的,所以资源块分配指示所占用的10个比特可以复用,由于跳频标识、上行延迟发送指示、信道状态信息请求指示为非必需指示,因此可选择任意2个比特复用。
这样,在UL-Grant消息中可以选择12个比特分别代表12个数据符号索引,在这12个比特中标记所映射的数据符号是否可用的指示信息,假设用1代表数据符号可用,0代表数据符号不可用。例如,12个比特用0、1、2……11标号,分别映射常规CP帧结构中数据符号0、1、2、4~9、11、12、13,若比特2的位置标记的指示信息为0,则代表数据符号2不可用,若比特5的位置标记的指示信息为1,则代表数据符号6可用。
这样,基站通过向UE发送UL-Grant消息,来指示UE在第二子帧上用来传输数据可占用的数据符号。
步骤405:在所述第二子帧到来之前,所述UE若接收到基站发送的分配传输资源的指令,则在所述第二子帧到来时,依据所述指令,在分配的传输资源上发送数据。
若在步骤404中基站为n个UE分配不同的传输资源,则UE在本步骤中,会接收到基站发送的分配传输资源的指令。
具体地,根据步骤404中所述的基站分配不同的传输的资源的两种方式,在本步骤中:
在第二子帧到来之前,UE若接收到基站发送的调度到与所述PUSCH资源不同的其他PUSCH资源的指令,则在所述第二子帧到来时,依据所述指令,在所述其他PUSCH资源上发送数据;或
在第二子帧到来之前,UE若接收到基站发送的指示信息,则在第二子帧到来时,依据指示信息,在所述PUSCH资源上,在第二子帧的该UE对应的数据符号上发送数据。
其中,UE接收基站发送的上行调度授权UL-Grant消息,根据所述UL-Grant消息中的可复用的比特与所述第二子帧的数据符号的映射关系,以及所述可复用的比特中标记的指示信息,确定所述UE对应的数据符号,并在所述PUSCH资源上,在第二子帧的所确定的数据符号上发送数据。
下面结合具体的应用场景对图4提供的传输方法做进一步详细的说明。以上述第一种分配不同传输资源的方法为例。
如图7所示,在SPS场景下,假设SPS周期固定,为4s。SPS调度的四个UE分别为UE1、UE2、UE3和UE4。在SPS配置被激活以后,UE1在子帧n上单独发送了数据,UE2和UE3需要在下一个子帧n+4上发送数据,而UE1不需要在子帧n+4上发送数据,则在子帧n上,UE2和UE3在指示符号上发送参考信号,通知基站需要在子帧n+4上发送数据。基站在子帧n上,根据各个UE分别对应的循环移位值对指示符号进行检测,确定UE2和UE3发送了参考信号,就可以
确定在子帧n+4上将会产生冲突,则基站在子帧n+2上向UE2发送UL-Grant消息,指示UE2的专用调度资源,UE2收到UL-Grant消息后,在基站指示的专用调度资源上发送数据,这样,可以完全避免了UE2和UE3在子帧n+4上发送数据时的冲突问题。
至此,本申请实施例二提供的通信方法介绍完毕,图4所示的传输方法适用于SPS场景,基站周期性地为多个UE分配相同的PUSCH资源,并在当前子帧上的指示符号上监测需要在下一个子帧上发送数据的UE的数目,一旦判定在下一个子帧上会产生冲突,提前为产生冲突的UE分配不同的传输资源,从而有效避免了多个UE同时使用PUSCH资源而产生冲突的问题,提高了资源利用效率,并解决了由于冲突造成的传输时延增大的问题。UE需要在下一个子帧上发送数据时,在当前子帧的指示符号上发送参考信号,通知基站其需要在下一个子帧上发送数据,若在下一个子帧到来之前,收到基站发送的专用调度,或者收到基站发送的用于指示UE在下一个子帧的某几个数据符号上发送数据的指示信息,则根据基站的指示,在下一个子帧上发送数据,这样,可以避免与其他UE共同使用同一个传输资源时产生的冲突问题,提高了上行传输的有效性和效率,减少了传输时延。
实施例三、
基于上述实施例一和实施例二相同的发明构思,本申请实施例三中,还提供另一种传输方法,不仅适用于SPS场景,也适用于预调度的场景。本申请实施例三的方法的核心思想是,将PUSCH资源上的时间资源进行划分,分别分配给调度的多个UE,UE只能在PUSCH资源上指定的时间资源上发送数据,并且为多个UE分别分配不同的循环移位值,当多个UE在相同的PUSCH资源上发送数据时,可以根据不同的循环移位值对多个UE的数据进行检测,从而可以有效避免多个UE同时使用相同的PUSCH资源时发生的冲突问题。
参阅图8所示,本申请实施例三提出的传输方法具体流程如下。
步骤801:基站为第一UE分配用于发送数据的PUSCH资源,并且,基站为所述第一UE配置资源请求参数以及在所述PUSCH资源上发送数据时占
用的时间资源,并通知给所述第一UE;其中,所述第一UE与所述至少一个第二UE共同使用所述PUSCH资源。
所述资源请求参数包括循环移位值、时频资源位置;
所述第一UE的循环移位值、在所述PUSCH资源上发送数据时占用的时间资源,均与所述至少一个第二UE的不同。
所述基站通过无线资源控制RRC消息或上行调度授权UL-Grant消息向所述第一UE通知资源请求参数和在所述PUSCH资源上发送数据时占用的时间资源。
步骤802:若基站在所述PUSCH资源上,根据为第一UE配置的资源请求参数,检测到所述第一UE发送的资源请求信息,则基站在所述PUSCH资源上所述第一UE占用的时间资源上,对所述第一UE发送的数据进行处理。
实施例四、
本申请中提供的实施例四与实施例三构思相同,对实施例三的方法应用于具体场景中,并作详细说明。
参阅图9所示,本申请实施例四提供的传输方法的流程如下。
步骤900:基站为N个UE分配相同的物理上行共享信道PUSCH资源,其中,N≥2,N为正整数。
分配相同的PUSCH资源的方法同图2所示的通信方法中所述,在此不再赘述。
在SPS场景中,基站通过RRC消息完成SPS配置,并通过RRC消息通知各个UE相应的循环移位值和相应的可用的数据符号;也可以通过PDCCH发送SPS激活消息,以激活SPS配置,在所述SPS激活消息中通知UE相应的循环移位值和相应的可用的数据符号。
在预调度场景中,基站可以通过RRC消息通知各个UE相应的循环移位值和相应的可用的数据符号,然后通过竞争专用的CB-RNTI对应的PDCCH消息同时各个UE开启竞争传输模式,在单独的预调度消息中携带使能标识,开启
只使用部分数据符号的功能。也可以通过扩展UL-Grant消息的内容,使其包含UE相应的循环移位值和相应的可用的数据符号。
其中,一个UE占用至少一个数据符号,所述N个UE占用的总的数据符号的数目不大于当前子帧上可用的数据符号的总数。
以上通知方式仅是举例,本申请实施例四不作具体限制。
步骤910:UE确定用于发送数据的物理上行共享信道PUSCH资源;并确定在所述PUSCH资源上所述UE对应的发送数据时可占用的数据符号,以及所述UE对应的循环移位值;其中,在所述PUSCH资源上复用至少两个UE。
UE在发送数据之前,接收基站通知的PUSCH资源、UE对应的循环移位值和UE对应的可占用的数据符号。
步骤920:UE根据UE对应的循环移位值,在当前子帧的所述UE对应的可占用的数据符号上发送数据。
UE需要发送数据时,直接在最近的一次可用的传输资源上,根据UE对应的循环移位值,在当前子帧上其对应的可占用的数据符号上发送数据。
步骤930:基站在PUSCH资源的当前子帧上,依据N个UE分别对应的循环移位值,对当前子帧上的导频符号进行检测,得到N个UE分别对应的检测结果。
其中,由于N个UE的循环移位值不同,因此当有多个UE都发送数据时,基站也能够区分出各个UE的信道估计结果,判断各个UE是否发送了数据。
步骤940:基站根据所述检测结果,在确定所述N个UE中的至少一个UE在所述当前子帧上发送数据时,在所述至少一个UE分别对应的发送数据时占用的数据符号上,分别对所述至少一个UE发送的数据进行处理。
在确定出哪些UE发送了数据,在这些发送数据的UE分别对应的占用的数据符号上进行解调和译码。
这样,通过本申请实施例三和实施例四的方法,多个UE虽然在相同的PUSCH资源上发送数据,但由于占用的数据符号不同,因此可以完全避免冲
突,又因为各个UE的循环移位值不同,因此可以对各个UE发送数据进行准确检测,再在UE对应的数据符号上进行解调和译码,完全避免了多个UE使用相同的PUSCH资源时的冲突,提高了上行数据传输的有效性和传输效率,避免了因冲突导致的传输时延增大的问题。
下面结合具体的应用场景对图9所示的传输方法作进一步详细的说明。
假设应用于SPS场景,如图10所示,仍以常规CP的子帧为例,一个子帧中包含14个符号,符号3和符号10用作导频符号,其余符号为数据符号。
为SPS调度的三个UE(假设为UE1、UE2、UE3)分配不同的循环移位值,和不同的可用数据符号,为UE1分配的循环移位值为0,可用的数据符号为0-2;为UE2分配的循环移位值为6,可用的数据符号为4-9;为UE3分配的循环移位值为9,可用的数据符号为11-13。
如图11所示,在SPS场景下,假设SPS周期固定,为4s。在SPS配置被激活以后,UE1有数据需要发送时,直接在最近一次子帧n上UE1对应的可用的数据符号上发送数据,也就是在数据符号0-2上发送数据。基站根据各个UE不同的循环移位值对导频符号进行检测,确定UE1发送了数据,则在UE1对应的数据符号0-2上进行解调和译码。
若在下一个发送子帧n+4上,UE1、UE2、UE3都需要发送数据,则UE1在其对应的数据符号0-2上发送数据、则UE2在其对应的数据符号4-9上发送数据、UE3在其对应的数据符号11-13上发送数据,基站根据各个UE不同的循环移位值对导频符号进行检测,确定3个UE都发送了数据,则在3个UE分别对应的数据符号上进行解调和译码。
同样,在子帧n+8上,UE3单独发送数据,在子帧n+12上UE2和UE3发送数据的原理相同,在此不再赘述。
