Description

物理层资源映射方法、装置、用户设备及基站 技术领域
本公开涉及通信技术领域，尤其涉及一种物理层资源映射方法、装置、用户设备及基站。
背景技术
在长期演进(Long Term Evolution，简称为LTE)系统中，当用户设备的上行数据的传输和上行控制信息的传输在时域上发生重合时，可以将待传输的上行控制信息作为待传输的上行数据的一部分，复用上行数据传输的时域和频域资源来实现上行控制信息的传输。在LTE中，上行混合自动重传应答消息(Hybrid Automatic Repeat reQuestAcknowledgement，简称为HARQ ACK)信息和上行数据进行复用传输时，HARQ-ACK调制符号会映射到紧邻两个解调参考信号(Demodulation Reference Signal，简称为DMRS)所在符号(symbol)的四个正交频分复用(Orthogonal Frequency Division Multiplexing，简称为OFDM)符号上，按照时域优先、频域由低到高的方式映射到相应资源元素(Resource Element，简称为RE)上。
由于在第五代移动通信技术(5th Generation，简称为5G)项目的研究讨论中，上行数据的RE映射是按照频域优先的方式映射的，而且引入了码块组(codeblock group，简称为CBG)的概念，因此在新一代网络，如5G网络中，使用LTE中的HARQ-ACK调制符号和上行数据复用的资源映射方式时，可导致被HARQ-ACK调制符号的数据RE属于可能属于同一个码块(codeblock，简称为CB)的数据，接收端可能将该码块上的数据视为误码，降低了上行数据传输的性能。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1A是根据一示例性实施例示出的一种物理层资源映射方法的流程图，图1B是根据一示例性实施例示出的一种物理层资源映射方法的场景图，图1C是根据一示例性实施例示出的一种物理层资源映射的示意图一；该物理层资源映射方法可以应用在用户设备上，如图1A所示，该物理层资源映射方法包括以下步骤101-102：
在步骤101中，在HARQ-ACK信息和上行数据复用传输时，确定HARQ-ACK调制符号映射到物理层资源上的起始位置和频域偏移值。
在一实施例中，频域偏移值为不同的HARQ-ACK调制符号所映射到的资源元素的频域偏移。
在一实施例中，可将紧邻上行数据的解调参考信号的正交频分复用符号的最低频域位置确定为起始位置，参见图1A中标记11或者12所标示的位置；在一实施例中，还可将除上行数据的解调参考信号之外的第一个正交频分复用符号的最低频域位置确定为起始位置，参见图1A中标记11所标示的位置，例如，如果解调参考信号所在正交频分复用符号前面的符号为空符号，则可将11所标示的位置确定为起始位置，如果解调参考信号所在正交频分复用符号前面的符号不为空符号，则可将标记13所标示的位置确定为起始位置。
在一实施例中，频域偏移值可以理解为不同的HARQ-ACK调制符号所映射到的资源元素的频域偏移。在一实施例中，频域偏移值可以基于HARQ-ACK调制符号可映射的正交频分复用符号的数目N、HARQ-ACK调制符号所占据的资源元素数目K，以及每一个正交频分复用符号所包含的资源元素数目M确定；在一实施例中，频域偏 移值也可以基于HARQ-ACK调制符号所占据的资源元素数目K，以及每一个正交频分复用符号所包含的资源元素数目M确定；在一实施例中，频域偏移值还可以为预设的固定值。
在步骤102中，基于起始位置和频域偏移值，将每一个HARQ-ACK调制符号映射到对应的资源元素上。
在一实施例中，由于HARQ-ACK信息和上行数据复用传输，因此在将每一个HARQ-ACK调制符号映射到对应的资源元素上时，对应资源元素上的上行数据调制符号将被取代。
在一实施例中，频域偏移值不相同，将每一个HARQ-ACK调制符号映射到对应的资源元素上的方式也不尽相同，可参见图2A-图7A所示实施例的描述，这里先不详述。
在一示例性场景中，如图1B所示，以移动网络为新一代网络，如5G网络并且基站为gNB为例进行示例性说明，在图1B所示的场景中，包括gNB10、UE20，其中，gNB10和UE20之间进行数据传输时，如果UE20侧同时有上行数据和HARQ-ACK要发送至gNB10，则可将HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上，避免了将HARQ-ACK调制符号集中分布在某一个或者几个正交频分复用符号上所导致的上行数据传输的性能降低的问题。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2A是根据一示例性实施例示出的另一种物理层资源映射方法的流程图，图2B是根据一示例性实施例示出的一种物理层资源映射的示意图二；本实施例利用本公开实施例提供的上述方法，以用户设备如何将HARQ-ACK调制符号映射到物理层资源上为例进行示例性说明，如图2A所示，包括如下步骤：
在步骤201中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置，并且基于HARQ-ACK调制符号可映射的正交频分复用符号的数目N、HARQ-ACK调制符号所占据的资源元素数目K，以及每一个正交频分复用符号所包含的资源元素数目M，确定频域偏移值。
在一实施例中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置的方式可参见图1A所示实施例的步骤101的描述，这里不再详述。
在一实施例中，可基于式(1)确定频域偏移值：
floor(M*N/K)式(1)
式(1)中，M为每一个正交频分复用符号所包含的资源元素数目，K为 HARQ-ACK调制符号所占据的资源元素数目，N为HARQ-ACK调制符号可映射的正交频分复用符号的数目。
在一实施例中，每一个正交频分复用符号所包含的资源元素数目可以为12、24等设定数目，而HARQ-ACK调制符号所占据的资源元素数目K可由用户设备根据基站侧配置和物理上行共享信道(Physical Uplink Shared Channel，简称为PUSCH)的资源分配计算得出，可基于协议约定计算得到，HARQ-ACK调制符号可映射的正交频分复用符号的数目N可以为上行数据传输使用的正交频分复用符号symbol除去DMRS以及PT-RS所占用symbol之后的剩余symbol数目。
在一实施例中，基于式(1)，假如K＝24，M＝24，N＝10，参见2B，可计算频域偏移值为floor(24×10/24)＝10，也即在一个HARQ-ACK调制符号的资源元素所在位置在频域方向上向下偏移10个资源元素后，即为下一个HARQ-ACK调制符号的资源元素所在位置。
在步骤202中，将第一个HARQ-ACK调制符号映射到起始位置所在资源元素。
在一实施例中，参见图2B，假设起始位置为标记21所指示的位置，则可将第一个HARQ-ACK调制符号映射到标记21所指示的起始位置所在资源元素。
在步骤203中，将剩余HARQ-ACK调制符号以频域优先的方式按照频域偏移值逐一映射到不同资源元素上，在频域偏移超过一个正交频分复用符号的频域范围时，顺序映射到下一个正交频分复用符号的资源元素上。
在一实施例中，将第一个HARQ-ACK调制符号映射到起始位置所在资源元素之后，可将剩余HARQ-ACK调制符号依次按照频域偏移值映射到对应的资源元素上，映射顺序可参见图2B中箭头所指示的顺序，也即在频域偏移超过一个正交频分复用符号的频域范围时，顺序映射到下一个正交频分复用符号的资源元素上。
本实施例中，公开了一种以频域优先的方式将HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上，避免了将HARQ-ACK调制符号集中分布在某一个或者几个正交频分复用符号上所导致的上行数据传输的性能降低的问题。以频域优先的方式实现了HARQ-ACK调制符号在上行数据的时频资源上的复用。
图3A是根据一示例性实施例示出的又一种物理层资源映射方法的流程图，图3B是根据一示例性实施例示出的一种物理层资源映射的示意图三；本实施例利用本公开实施例提供的上述方法，以用户设备如何将HARQ-ACK调制符号映射到物理层资源上为例进行示例性说明，如图3A所示，包括如下步骤：
在步骤301中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置， 并且基于HARQ-ACK调制符号可映射的正交频分复用符号的数目N、HARQ-ACK调制符号所占据的资源元素数目K，以及每一个正交频分复用符号所包含的资源元素数目M，确定频域偏移值。
在一实施例中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置的方式可参见图1A所示实施例的步骤101的描述，这里不再详述。
在一实施例中，可基于式(2)确定频域偏移值：
Figure PCTCN2017111350-appb-000001
式(2)中，M为每一个正交频分复用符号所包含的资源元素数目，K为HARQ-ACK调制符号所占据的资源元素数目，N为HARQ-ACK调制符号可映射的正交频分复用符号的数目。
在一实施例中，每一个正交频分复用符号所包含的资源元素数目可以为12、24等设定数目，而HARQ-ACK调制符号所占据的资源元素数目K可由用户设备根据基站侧配置和PUSCH的资源分配计算得出，可基于协议约定计算得到，HARQ-ACK调制符号可映射的正交频分复用符号的数目N可以为上行数据传输使用的正交频分复用符号symbol除去DMRS以及PT-RS所占用symbol之后的剩余symbol数目。
在一实施例中，基于式(2)，假如K＝24，M＝24，N＝10，参见3B，可计算频域偏移值为floor(24/ceil(24/10))＝8，也即在一个HARQ-ACK调制符号的资源元素所在位置在频域方向上向下偏移8个资源元素后，即为下一个HARQ-ACK调制符号的资源元素所在位置。
在步骤302中，将HARQ-ACK调制符号分割为P个符号组，每一个符号组包含最多N个HARQ-ACK调制符号。
在一实施例中，参见步骤301的示例，假设HARQ-ACK调制符号可映射的正交频分复用符号的数目为10，而HARQ-ACK调制符号的资源元素数目为24，由于每一个符号组包括最多10个HARQ-ACK调制符号，因此可将HARQ-ACK调制符号分割为3组，第一组和第二组各包括10个HARQ-ACK调制符号，第三组包括4个HARQ-ACK调制符号，或者还可以三组符号都包括8个HARQ-ACK调制符号。
在步骤303中，将第一组HARQ-ACK调制符号逐一映射到起始位置所在频域位置的不同资源元素上。
在步骤304中，基于起始位置所在频域位置和频域偏移值，确定剩余组HARQ-ACK调制符号中每一组HARQ-ACK调制符号所映射的频域位置。
在步骤305中，将剩余组HARQ-ACK调制符号以时域优先的方式映射到对应 组的频域位置的不同资源元素上。
在一实施例中，在步骤303-步骤305中，可将第一组HARQ-ACK调制符号逐一映射到起始位置所在频域位置的不同资源元素上，然后基于第一组起始位置所在频域位置和频域偏移值确定出第二组以及后续各组对应的频域位置，参见图3B，频域偏移值为8，因此可确定出后续组的频域位置分别为9、17，剩余组也以时域优先的方式映射到对应组的频域位置的不同资源元素上。
本实施例中，公开了一种以时域优先的方式将HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上，避免了将HARQ-ACK调制符号集中分布在某一个或者几个正交频分复用符号上所导致的上行数据传输的性能降低的问题。以时域优先的方式实现了HARQ-ACK调制符号在上行数据的时频资源上的复用。
图4A是根据一示例性实施例示出的又一种物理层资源映射方法的流程图，图4B是根据一示例性实施例示出的一种物理层资源映射的示意图四；本实施例利用本公开实施例提供的上述方法，以用户设备如何将HARQ-ACK调制符号映射到物理层资源上为例进行示例性说明，如图4A所示，包括如下步骤：
在步骤401中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置，并且基于HARQ-ACK调制符号所占据的资源元素数目K与每一个正交频分复用符号所包含的资源元素数目M，确定频域偏移值。
在一实施例中，确定HARQ-ACK调制符号映射到物理层资源上的起始位置的方式可参见图1A所示实施例的步骤101的描述，这里不再详述。
在一实施例中，可基于式(3)确定频域偏移值：
ceilM/K)式(3)
式(3)中，M为每一个正交频分复用符号所包含的资源元素数目，K为HARQ-ACK调制符号所占据的资源元素数目。
在步骤402中，在起始位置所在频域位置开始以时域优先的方式，将Q个HARQ-ACK调制符号映射到频域位置相同的不同资源元素上后，按照频域偏移值偏移后继续映射下一Q个HARQ-ACK调制符号到不同的资源元素上，Q基于K和M计算得到。
在一实施例中，可基于式(4)确定Q值：
ceilK/M)式(4)
式(4)中，M为每一个正交频分复用符号所包含的资源元素数目，K为HARQ-ACK调制符号所占据的资源元素数目。
在一实施例中，在步骤401-步骤402中，基于式(3)和式(4)，假如K＝24，M＝24，N＝10，参见4B，可计算频域偏移值为ceil(24/24)＝1，Q值为ceil(24/24)＝1，也即频域偏移值为1，每一个频域位置映射有ceil(24/24)＝1个HARQ-ACK调制符号。
本实施例中，公开了一种以时域优先的方式将HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上，基于每一个正交频分复用符号所包含的资源元素数目以及HARQ-ACK调制符号所占据的资源元素数目，确定出频域偏移值和每一个频域偏移值所对应的HARQ-ACK调制符号映射的资源元素数目，避免了将HARQ-ACK调制符号集中分布在某一个或者几个正交频分复用符号上所导致的上行数据传输的性能降低的问题。以时域优先的方式实现了HARQ-ACK调制符号在上行数据的时频资源上的复用。
图5A是根据一示例性实施例示出的又一种物理层资源映射方法的流程图，图5B是根据一示例性实施例示出的一种物理层资源映射的示意图五，图5C是根据一示例性实施例示出的一种物理层资源映射的示意图六；本实施例利用本公开实施例提供的上述方法，以用户设备如何将HARQ-ACK调制符号映射到物理层资源上为例进行示例性说明，如图5A所示，包括如下步骤：
在步骤501中，确定HARQ-ACK调制符号所占据的资源元素数目K是否大于每一个正交频分复用符号所包含的资源元素数目M，在K大于M时，执行步骤506，在K不大于M时，执行步骤502。
在步骤502中，采用第一算法确定前R个HARQ-ACK调制符号对应的第一频域偏移值，采用第二算法确定除前R个HARQ-ACK调制符号之外的HARQ-ACK调制符号对应的第二频域偏移值。
在一实施例中，第一算法可以通过式(3)确定第一频域偏移值，以计算每一次频域偏移需要偏移多少个资源元素，R的值可以通过式(5)计算得到：
mod(M，K)式(5)
在一实施例中，第二算法可通过式(6)计算得到第二频域偏移值：
floor(M/K)式(6)
在步骤503中，将前R个HARQ-ACK调制符号以时域优先的方式，从起始位置起按照第一频域偏移值逐一映射到不同频域位置的不同资源元素上。
在步骤504中，基于第R个HARQ-ACK调制符号所在频域位置和第二频域偏移值，确定第R+1个HARQ-ACK调制符号映射的资源元素。
在步骤505中，将除前R个HARQ-ACK调制符号之外的HARQ-ACK调制符号以时域优先的方式，从第R+1个HARQ-ACK调制符号映射的资源元素的位置起按照第二频域偏移值逐一映射到不同频域位置的不同资源元素上。
在一实施例中，在步骤503-步骤505中，参见图5B，假设K＝9，M＝12，N＝10，起始位置为解调参考信号相邻右侧符号的最低频域位置，则可确定第一频域偏移值为ceil(12/9)＝2，第二频域偏移值为floor(12/9)＝1，R值为mod(12，9)＝3，也即前3个映射资源元素的频域偏移值为2，之后的资源元素的频域偏移为1。
在步骤506中，采用第四算法确定HARQ-ACK调制符号的前S次偏移中每一个频域位置上HARQ-ACK调制符号映射到的资源元素对应的第一计数，采用第五算法确定除前S次偏移之外的HARQ-ACK调制符号偏移中每一个频域位置上HARQ-ACK调制符号映射到的资源元素对应的第二计数。
在一实施例中，第四算法可以通过式(4)确定第一计数，第五算法可以采用式(7)计算得到第二频域偏移值：
floor(K/M)式(7)
在一实施例中，S的值基于第六算法计算得到，第六算法可以采用式(8)计算得到S值：
mod(K，M)式(8)
在一实施例中，前S次偏移对应的频域偏移值为第一设定值，除前S次偏移之外的频域偏移的频域偏移值为第二设定值。
在一实施例中，第一设定值和第二设定值可以基站预先设定的值，如均为1。
在步骤507中，将前S次频域偏移中，以时域优先的方式在起始位置所在频域位置起并按照第一设定值进行频域偏移，每一个频域位置连续映射第一计数个HARQ-ACK调制符号。
在步骤508中，基于起始位置所在频域位置、第一设定值、第二设定值，确定出第S+1次偏移对应的起始位置。
在步骤509中，在执行完前S次偏移之后，以时域优先的方式在第S+1次偏移对应的起始位置所在位置起起并按照第一设定值进行频域偏移，每一个频域位置连续映射第二计数个HARQ-ACK调制符号。
在一实施例中，在步骤507-步骤509中，参见图5C，假设K＝16，M＝12，N＝10，第一设定值和第二设定值均为1，起始位置为解调参考信号相邻右侧符号的最低频域位置，则可确定第一计数为ceil(16/12)＝2，第二计数为floor(16/12)＝1，S值为 mod(16，12)＝4，也即前4次偏移对应的频域偏移中，每一个频域位置映射2个资源元素，频域偏移值为1，之后的每一个频域位置映射1个资源元素，频域偏移值为1。
本实施例中，公开了一种以时域优先的方式将HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上，基于每一个正交频分复用符号所包含的资源元素数目以及HARQ-ACK调制符号所占据的资源元素数目的大小，采用不同的映射算法确定出频域偏移值和每一个频域偏移值所对应的HARQ-ACK调制符号映射的资源元素数目，资源映射的方式更多样化。
在一实施例中，上述图2A-图5A中，以通过式(1)-式(8)等不同的算法计算频域偏移值等映射参数为例进行示例性说明，本公开还可以通过其它的算法来获取频域偏移值等参数；对于上述实施例中涉及的HARQ-ACK调制符号映射方法中的不同映射方案，还可以调整式(1)-式(8)的顺序来获取对应的映射方法中的映射参数，本公开并不对采用每一种映射方式时所使用的计算公式进行限制。

在一实施例中，在确定出HARQ-ACK调制符号可映射资源元素之后，可在HARQ-ACK调制符号可映射资源元素中基于起始位置和频域偏移值选择出将HARQ-ACK调制符号映射到哪些资源元素上。
在步骤603中，基于起始位置和频域偏移值，将HARQ-ACK调制符号映射到可映射符号中的资源元素上。
在一实施例中，参见图6B，示意了将CSI调制符号在紧邻解调参考信号的符号上均匀地分布在整个频率资源上，而在最后一个正交频分复用符号上频域连续分布在尾部的映射方式，这里只是一种映射示意，并不限定CSI调制符号映射到的资源元素，CSI调制符号具体映射到的资源元素可以由基站约定；并且将除CSI调制符号映 射到的资源元素所在正交频分复用符号之外的资源元素确定为HARQ-ACK调制符号可映射资源元素，实现的以时域优先的方式的HARQ-ACK调制符号到物理层资源的映射。
在一实施例中，可采用图2A-图5A所示意的HARQ-ACK调制符号的映射方法确定出HARQ-ACK调制符号映射到哪些资源元素上。

在一实施例中，步骤701和步骤702的描述可参见图1A所示实施例的描述方法，这里不再详述。
在步骤703中，将除HARQ-ACK调制符号映射到的资源元素之外的资源元素确定为CSI调制符号可映射资源元素。
在步骤704中，将CSI调制符号按照预设映射规则映射到CSI调制符号可映射资源元素。
在一实施例中，预设映射规则可以理解为CSI调制符号的映射规则，CSI信息可以包括两部分信息，这两部分信息可以分别以不同的方式映射到不同的资源元素上去，预设映射规则可以由基站约定。
本实施例中，公开了一种在CSI、HARQ-ACK信息和上行数据三者复用传输时，将CSI调制符号和HARQ-ACK调制符号映射到物理层资源上的实现方式，有助于用户设备将CSI调制符号和HARQ-ACK调制符号在频域上均匀地分布到尽可能多的正交频分复用符号上。
