Description

一种下行数据传输的缓存方法、终端及基站
相关申请的交叉引用
本申请主张在2017年9月8日在中国提交的中国专利申请No.201710807988.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域,特别涉及一种下行数据传输的缓存方法、终端及基站。
背景技术
在LTE(Long Term Evolution,长期演进技术)系统中,终端在一个TTI(Transmission Time Interval,传输时间间隔)内最多只能接收一个PDSCH(Physical Downlink Shared Channel,物理下行共享信道)或者发送一个PUSCH(Physical Uplink Shared Channel,物理上行共享信道)。因此在一个TTI中只能接收到对应一个HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)进程编号的一个PDSCH,PDSCH传输的HARQ进程对于终端来说是明晰的。当终端没有正确接收下行数据时,可以根据DCI(Downlink Control Information,下行控制信息)中携带的HARQ进程ID,识别不同的HARQ进程,不同的HARQ进程对应不同的缓冲buffer存储位置,终端可以根据HARQ进程编号确定buffer存储位置,从而在buffer中进行数据存储和重传合并。
但是在5G系统中,终端在同一个TTI内可以同时接收两个PDSCH。两个PDSCH可以来自不同的TRP(Transmission Receiving Point,传输接收点),承载不同的TB(Transport Block,传输块)信息,因此可以对应两个独立的HARQ进程。当不同TRP对HARQ进程ID的编号范围相同时(例如都是从0到7),两个PDSCH可能对应相同的HARQ进程ID,此时,终端在一个TTI中接收到两个对应同一个HARQ进程编号的PDSCH,终端无法确定如何缓存来自两个TRP的PDSCH,从而可能导致与不对应的数据进行合并,导 致重传失败。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
在本公开的一些实施例中,参照图1所示,提供了一种下行数据传输的缓存方法,包括:
步骤101,获取下行传输相关的参数的分组信息。
这里,通过获取下行传输相关的参数的分组信息,为后续确定PDSCH的缓存位置提供了支持。
其中,可通过基站将下行传输相关的参数进行分组,并将分组信息发送给终端。
进一步的,基站可通过高层信令将分组信息发送给终端。此时,上述步骤101包括:
接收基站通过高层信令发送的下行传输相关的参数的分组信息。
步骤102,根据所述分组信息,确定接收到的物理下行共享信道PDSCH对应的缓存位置。
这里,根据分组信息,确定接收到的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
本公开实施例的下行数据传输的缓存方法,根据下行传输相关的参数的分组信息,确定PDSCH对应的缓存位置,可以保证当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。
可选地,上述步骤101包括:
步骤1011,获取与用于调度PDSCH的下行控制信道PDCCH相关的参数的分组信息。
这里,通过获取与用于调度PDSCH的PDCCH相关的参数的分组信息,可基于与PDCCH相关的参数的分组信息,确定PDCCH调度的PDSCH对应的缓存位置。
其中,可通过基站将与用于调度PDSCH的PDCCH相关的参数进行分组,并将分组信息发送给终端。
或者步骤1012,获取与PDSCH相关的参数的分组信息。
这里,通过获取与PDSCH相关的参数的分组信息,可基于与PDSCH相关的参数的分组信息,确定PDSCH对应的缓存位置。
其中,可通过基站将与PDSCH相关的参数进行分组,并将分组信息发 送给终端。
其中,所述分组信息包括对同一种参数分组得到的至少一个小组,每个小组包含至少一个参数,不同小组包含的参数的参数值不同。
这里,可通过基站将与PDCCH相关的一种参数或者与PDSCH相关的一种参数进行分组,得到至少一个小组,每个小组包含至少一个参数,不同小组包含的参数的参数值不同。
由于不同小组包含的参数的参数值不同,因此可基于接收到的PDCCH或者PDSCH相关的参数的参数值,准确确定出接收到的PDCCH或者PDSCH相关的参数所归属的小组,进而确定PDSCH对应的缓存位置。
其中,归属于不同小组的参数对应不同的缓存位置。
需要说明的是,通过基站将与PDCCH或者PDSCH相关的一种参数进行分组时,对于一个终端,可将与PDCCH或者PDSCH相关的参数的所有参数值进行分组,以避免由于分组时遗漏某个参数导致无法确定其对应的小组。
作为一种可选的实现方式,上述步骤1011包括:
获取与用于调度PDSCH的PDCCH相关的准共站址QCL、波束或者波束对链接BPL的分组信息。
这里,通过获取与用于调度PDSCH的PDCCH相关的,QCL(Quasi Co Located,准共站址)、波束或者BPL(Beam Pair Link,波束对链接)的分组信息,可基于PDCCH相关的QCL、波束或者BPL的分组信息,确定PDCCH调用的PDSCH对应的缓存位置。
其中,可通过基站将与用于调度PDSCH的PDCCH相关的QCL、波束或者BPL分为至少一个小组,每个小组中包含至少一个QCL、波束或者BPL参数,且不同小组包含的QCL、波束或者BPL参数的参数值均不相同。
下面对基于QCL、波束或者BPL的分组信息,确定PDCCH调用的PDSCH对应的缓存位置进行详细介绍。
可选地,所述分组信息包括与用于调度PDSCH的PDCCH相关的QCL的分组信息。
这里,可通过基站将与用于调度PDSCH的PDCCH相关的QCL分为至少一个小组,每个小组包含至少一个QCL,且不同小组包含的QCL不同。
其中,对于一个终端,可将基站配置的PDCCH传输时相关的所有QCL进行分组。例如,假设对于一个终端,其PDCCH传输时相关的QCL共有N个,可通过基站将N个QCL分为至少一个小组。N为正整数。
上述步骤102包括:
步骤1021,确定接收到的PDCCH对应的QCL。
这里,首先确定接收到的PDCCH对应的QCL,以便于后续基于该QCL确定归属的小组。
其中,终端在确定接收PDCCH时,需要根据基站配置的QCL信息,在每个QCL确定的波束上尝试接收PDCCH。其中QCL可以对应不同的CORESET(Control Resource Set,控制资源集合)或者不同的CORESET组,也可以分别对应同一个CORESET内的不同PDCCH候选位置candidate,本实施例中并不做限制。
步骤1022,根据QCL的分组信息,确定所述PDCCH对应的QCL归属的小组。
这里,由于QCL的分组信息包括至少一个小组,每个小组包含至少一个QCL,且每个小组包含的QCL不同,因此根据QCL的分组信息,能够准确确定PDCCH对应的QCL归属的小组。
步骤1023,根据所述PDCCH对应的QCL归属的小组,确定所述PDCCH调度的PDSCH对应的缓存位置。
这里,根据PDCCH对应的QCL归属的小组,确定PDCCH调度的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
其中,归属于不同小组的参数对应不同的缓存位置。
例如,假设波束由QCL参数确定。假设对于一个终端,其PDCCH传输时相关的QCL共有N个,假设N=6。可通过基站将6个QCL分为两个小组,小组A为{QCL1,QCL2,QCL3},小组B为{QCL4,QCL5,QCL6}。
假设基站为终端配置了6个CORESET,不同的CORESET对应于不同的QCL,也即不同的CORESET对应于不同的波束方向。终端需要在不同的CORESET内按照对应的QCL确定的波束,确定接收PDCCH。
假设终端在CORESET1上确定接收到调度PDSCH1的PDCCH,且其对应的QCL为QCL1。同时,终端在CORESET5上确定接收到调度PDSCH2的PDCCH,且其对应的QCL为QCL4。同时假设PDSCH1和PDSCH2对应的HARQ process ID均为1,且均没有正确接收,终端需要对PDSCH1以及PDSCH2承载的数据进行缓存,以便与重传数据进行合并。此时,终端根据调度PDSCH的PDCCH对应的QCL所归属的小组,确定如何缓存没有正确接收的数据。
终端根据调度PDSCH1的PDCCH对应的QCL1,确定该QCL1归属于小组A,则将数据缓存至HARQ buffer1,并与后续采用相同HARQ process ID传输且调度PDCCH相关的QCL归属于小组A的数据进行合并。当然,如果后续采用相同HARQ process ID传输且调度PDCCH相关的QCL归属于小组A的数据仍然没有成功接收,则继续将数据存储至HARQ buffer1。同时终端根据调度PDSCH2的PDCCH对应的QCL4,确定QCL4归属于小组B,则将数据缓存至HARQ buffer2,并与后续采用相同HARQ process ID(HARQ过程ID)传输且调度PDCCH对应的QCL归属于小组B的数据进行合并。当然,如果后续采用相同HARQ process ID且调度PDCCH对应的QCL归属于小组B的数据仍然没有成功接收,则继续将数据存储至HARQ buffer2。
其中,HARQ buffer为终端在内存空间内根据一定规则(例如,支持的HARQ process个数、传输模式、终端硬件支持的最大存储容量等因素)划分的虚拟存储空间,不同的HARQ buffer占有不同的存储空间位置。本实施例中对于HARQ buffer的数量、如何划分、资源如何分配并不做具体限制。
一个简单的例子,如图2所示,PDSCH1和PDSCH2来自于两个不同的TRP,且具有相同的HARQ process ID,例如均为1。初传时,调度PDSCH1的PDCCH1在QCL1确定的波束1上传输,调度PDSCH2的PDCCH2在QCL4确定的波束2上传输。由于两者均没有成功接收,因此需要进行重传。重传时,调度PDSCH1重传的PDCCH1在QCL2确定的波束3上传输,调度PDSCH2重传的PDCCH仍然在QCL4确定的波束2上传输。终端可以根据调度PDCCH对应的QCL归属的QCL分组的不同,确定每个PDSCH对应的HARQ buffer。当然,PDSCH1和PDSCH2的重传可能发生在不同的TTI上, 本实施例中并不做限定。
进一步的,具有相同HARQ进程编号的PDSCH1和PDSCH2的初传并不限定在同一个TTI内。
至此,根据用于调度PDSCH的PDCCH相关的QCL的分组信息,确定PDCCH对应的QCL归属的小组,进而确定PDCCH调度的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。
可选地,所述分组信息包括与用于调度PDSCH的PDCCH相关的波束的分组信息。
这里,可通过基站将与用于调度PDSCH的PDCCH相关的波束分为至少一个小组,每个小组包含至少一个波束,且不同小组包含的波束不同。
其中,对于一个终端,可将基站配置的PDCCH传输时相关的所有波束进行分组。
上述步骤102包括:
步骤1024,确定接收到的PDCCH对应的波束。
这里,首先确定接收到的PDCCH对应的波束,以便于后续基于该QCL确定归属的小组。
步骤1025,根据波束的分组信息,确定所述PDCCH对应的波束归属的小组。
这里,由于波束的分组信息包括至少一个小组,每个小组包含至少一个波束,且每个小组包含的波束不同,因此根据波束的分组信息,能够准确确定PDCCH对应的波束归属的小组。
步骤1026,根据所述PDCCH对应的波束归属的小组,确定所述PDCCH调度的PDSCH对应的缓存位置。
这里,根据PDCCH对应的波束归属的小组,确定PDCCH调度的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
其中,归属于不同小组的参数对应不同的缓存位置。
此时,根据用于调度PDSCH的PDCCH相关的波束的分组信息,确定PDCCH对应的波束归属的小组,进而确定PDCCH调度的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。

上述步骤102包括:
步骤1027,确定接收到的PDCCH对应的BPL。
这里,首先确定接收到的PDCCH对应的BPL,以便于后续基于该BPL确定归属的小组。
步骤1028,根据BPL的分组信息,确定所述PDCCH对应的BPL归属的小组。
这里,由于BPL的分组信息包括至少一个小组,每个小组包含至少一个BPL,且每个小组包含的BPL不同,因此根据BPL的分组信息,能够准确确定PDCCH对应的BPL归属的小组。

作为一种可选的实现方式,上述步骤1012包括:

其中,对于一个终端,可将基站配置的PDSCH传输时相关的所有QCL进行分组。例如,假设对于一个终端,其PDSCH传输时相关的QCL共有M个,可通过基站将M个QCL分为至少一个小组。M为正整数。
上述步骤102包括:
步骤10210,获取下行控制信息DCI中携带的PDSCH对应的QCL信息。
这里,首先获取DCI中携带的PDSCH对应的QCL信息,以便于后续基于该QCL确定归属的小组。
步骤10211,根据QCL的分组信息,确定所述PDSCH对应的QCL归属的小组。
这里,由于QCL的分组信息包括至少一个小组,每个小组包含至少一个QCL,且每个小组包含的QCL不同,因此根据QCL的分组信息,能够准确确定PDSCH对应的QCL归属的小组。
步骤10212,根据所述PDSCH对应的QCL归属的小组,确定所述PDSCH对应的缓存位置。
这里,根据PDSCH对应的QCL归属的小组,确定PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
其中,归属于不同小组的参数对应不同的缓存位置。
例如,假设对于一个终端,其PDSCH传输时相关的QCL共有M个,假设M=10。可通过基站将10个QCL分为两个小组,小组C为{QCL1 QCL2 QCL3 QCL4 QCL5},小组D为{QCL6 QCL7 QCL8 QCL9 QCL10}。PDSCH对应的QCL参数由调度该PDSCH的DCI中携带。
假设终端可以同时接收两个独立的PDSCH,且两个PDSCH具有独立的HARQ进程,且HARQ进程的编号范围一致,例如均为1-8。当两个PDSCH的相同HARQ process ID的数据需要重传时,终端根据调度两个终端的DCI中携带的QCL参数归属的小组,确定PDSCH数据缓存的HARQ buffer。
假设PDSCH1和PDSCH2的HARQ process ID均为2。当终端没有正确接收PDSCH1时,终端需要根据PDSCH1对应的QCL4,确定QCL4归属于小组C,进而确定将数据存储至对应的HARQ buffer X1,以便在HARQ process2上与PDSCH1后续的重传数据进行合并。当终端没有正确接收PDSCH2时,终端需要根据PDSCH2对应的QCL8,确定QCL8归属于小组D,进而确定将数据存储至对应的HARQ buffer Y1,以便在HARQ process2上与PDSCH2后续的重传数据进行合并。HARQ buffer X1与HARQ buffer Y1是相互不重叠的存储区域,即使终端同时接收到两个具有相同HARQ进程编号的PDSCH,也不能存储到相同的位置,因为这两个PDSCH承载的原始信息不同,虽然HARQ进程编号相同,但是属于来自不同TRP的不同的两个HARQ进程。
当然,初传PDSCH对应的QCL和重传PDSCH对应的QCL可以不同。如上文中所述,在此不再赘述。
至此,根据PDSCH相关的QCL的分组信息,确定PDSCH对应的QCL归属的小组,进而确定PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。

这里,根据PDCCH传输波束对应的参考信号端口归属的小组,确定PDCCH调度的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
其中,归属于不同小组的参考信号端口对应不同的缓存位置。
例如,假设对于一个终端,基站为其配置了W个用于波束管理或者测量的CSI-RS端口,W=6。可通过基站将6个CSI-RS端口分为两个小组,小组E为{P1,P2,P3},小组F为{P4,P5,P6}。并通过高层信令将分组信息发送给终端。终端确定接收到PDCCH后,根据该PDCCH所在的波束,确定该波束对应的CSI-RS端口,从而确定PDCCH调度的PDSCH对应的HARQ buffer。
假设终端可以同时接收两个独立的PDSCH,且两个PDSCH具有独立的 HARQ进程,且HARQ进程的编号范围一致,例如均为1-8。当两个PDSCH的相同HARQ process ID的数据需要重传时,终端根据调度两个终端的PDCCH传输波束对应的CSI-RS端口归属的小组,确定PDSCH数据缓存的HARQ buffer。
假设PDSCH1和PDSCH2的HARQ process ID均为1。当终端没有正确接收PDSCH1时,终端需要根据调度PDSCH1的PDCCH传输波束对应的CSI-RS端口P1,确定P1归属于小组E,进而确定将数据存储至对应的HARQ buffer X2,以便在HARQ process1上与PDSCH1后续的重传数据进行合并。当终端没有正确接收PDSCH2时,终端需要根据调度PDSCH2的PDCCH传输波束对应的CSI-RS端口P6,确定P6归属于小组F,进而确定将数据存储至对应的HARQ buffer Y2,以便在HARQ process1上与PDSCH2后续的重传数据进行合并。HARQ buffer X2与HARQ buffer Y2是相互独立的存储区域。
当然,调度初传PDSCH的PDCCH传输波束对应的CSI-RS端口和调度重传PDSCH的PDCCH传输波束对应的CSI-RS端口可以不同。如上文中所述,在此不再赘述。
至此,根据PDCCH传输波束相关的波束管理或测量使用的参考信号端口的分组信息,确定PDCCH对应的参考信号端口归属的小组,进而确定PDCCH调用的PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。

其中,可通过基站,将与PDSCH传输波束相关的波束管理或测量使用的参考信号端口分为至少一个小组,每个小组中包含至少一个参考信号端口,且不同小组包含的参考信号端口均不相同。
其中,波束管理或测量使用的参考信号端口如可以是CSI-RS端口,但不限于此。
其中,对于一个终端,可将基站配置的PDSCH传输波束相关的所有参考信号端口进行分组。例如,假设对于一个终端,其PDSCH传输波束相关的CSI-RS端口共有M个,可通过基站将M个CSI-RS端口分为至少一个小组。M为正整数。
可选地,上述步骤102包括:
步骤10222,确定PDSCH传输波束对应的参考信号端口。
这里,首先确定PDSCH传输波束对应的参考信号端口,以便于后续基于该参考信号端口确定归属的小组。
步骤10223,根据参考信号端口的分组信息,确定所述PDSCH传输波束对应的参考信号端口归属的小组。
这里,由于参考信号端口的分组信息包括至少一个小组,每个小组包含至少一个参考信号端口,且每个小组包含的参考信号端口不同,因此根据参考信号端口的分组信息,能够准确确定PDSCH对应的参考信号端口归属的小组。
步骤10224,根据所述PDSCH传输波束对应的参考信号端口归属的小组,确定所述PDSCH对应的缓存位置。
这里,根据PDSCH传输波束对应的参考信号端口归属的小组,确定PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突。
其中,归属于不同小组的参考信号端口对应不同的缓存位置。
例如,假设对于一个终端,基站为其配置了M个用于波束管理或者测量的CSI-RS端口,M=6。可通过基站将6个CSI-RS端口分为两个小组,小组G为{P1,P2,P3},小组H为{P4,P5,P6}。并通过高层信令将分组信息发送给终端。终端接收到PDSCH后,根据该PDSCH所在的波束,确定该波束对应的CSI-RS端口,从而确定PDSCH对应的HARQ buffer。
假设终端可以同时接收两个独立的PDSCH,且两个PDSCH具有独立的HARQ进程,且HARQ进程的编号范围一致,例如均为1-8。当两个PDSCH 的相同HARQ process ID的数据需要重传时,终端根据调度两个PDSCH传输所在的波束对应的CSI-RS端口归属的小组,确定PDSCH数据缓存的HARQ buffer。
假设PDSCH1和PDSCH2的HARQ process ID均为2。当终端没有正确接收PDSCH1时,终端需要根据PDSCH1传输所在波束对应的CSI-RS端口P2,确定P2归属于小组G,进而确定将数据存储至对应的HARQ buffer X3,以便在HARQ process2上与PDSCH1后续的重传数据进行合并。当终端没有正确接收PDSCH2时,终端需要根据PDSCH2传输所在波束对应的CSI-RS端口P5,确定P5归属于小组H,进而确定将数据存储至对应的HARQ buffer Y3,以便在HARQ process2上与PDSCH2后续的重传数据进行合并。HARQ buffer X3与HARQ buffer Y3是相互独立的存储区域。
当然,初传PDSCH传输波束和重传PDSCH波束可以不同,对应的CSI-RS端口也可以不同。如上文中所述,在此不再赘述。
至此,根据PDCCH传输波束相关的波束管理或测量使用的参考信号端口的分组信息,确定PDCCH对应的参考信号端口归属的小组,进而确定PDSCH对应的缓存位置,保证了当终端同时接收到两个PDSCH时,具有相同HARQ进程号的下行数据缓存时不会出现冲突,同时避免了在DCI中引入额外的指示位指示HARQ进程号。
