请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
以多TTI的PDSCH传输调度为例，如图2示意，一个DCI调度了4个PDSCH传输，分别是PDSCH1、 PDSCH2、PDSCH3和PDSCH4。4个PDSCH传输分属于不同的时隙。图2中显示的是4个PDSCH所在的时隙是相邻的情况，但是也不排除存在各个PDSCH传输所在的时隙并不相邻的情况，例如，前后2个PDSCH传输之间间隔2个时隙。该场景下，多个TTI调度的PDSCH可用于数据的重复传输，也可分别传输不同的下行数据，也即不同的传输块(Transport Block，TB)。
对于单个PDSCH/PUSCH调度的情况，DCI中会指示用于传输的PDSCH/PUSCH的频域资源。例如，终端被半静态配置的带宽部分(bandwidth part，BWP)的资源块(Resource Block，RB)编号为RB0-RB49。如果采用集中式的频域资源分配方式，DCI在调度PDSCH时可以指定集中式的频域资源分配方式，例如指定分配RB10至RB19。如果采用比特位图(bitmap)指示RB组(group)的方式。例如，RB0-RB49总共被分成7组，分别为RB0-7、RB8-15、RB16-23、RB24-31、RB32-39、RB40-48及RB48-49，一共需要7个比特来指示，例如指示为0101000时，表示分配给UE的频域RB为RB8-15及24-31。
为了提高频域分集增益，在本公开实施例中提供一种方法，针对多TTI调度的多个传输，若是由集中式的频域资源分配方式进行资源分配，则采用跳频传输。
如图1所示，本公开实施例提供一种无线通信方法，应用于终端中，所述方法包括：
S110：跳频传输多传输时间间隔TTI传输。
在本公开实施例中该终端可为各种类型的终端，例如，手机、平板电脑或者车载终端等；该终端还可以是物联网终端。该物联网终端包括但不限于：智能水表和/或智能电表等。
该终端可为宽带终端或者窄带终端等。
例如，多TTI传输，可以理解为多TTI调度的传输是在一端集中式的频域资源传输，则采用跳频传输时，多TTI传输在时域上相邻的两个TTI传输采用跳频传输时则使用的是不同的频域资源，如此，提升了多TTI传输的频域分集增益。
例如，这多TTI传输的可是一个TB的多次重复传输，则通过跳频传输即便最终该多TTI传输使用了集中式的频域资源传输，但是时域上相邻两次TTI传输使用的是不同频域资源，从而提升了频域分集增益，提升了传输质量。
跳频传输的方式有多种，具体使用哪一种跳频传输方式，在本公开实施例中不做任何限定。以下提供两种可选的跳频传输方式：
方式一：
DCI指示跳频传输带传输的起始频域资源位置，在进行跳频传输时，间隔预设带宽进行跳频传输，该预设带宽可为1/N的系统带宽；该N可为任意大于或等于2的正整数；
方式二：
将虚拟资源块(Vitual Resource Block，VRB)映射到不同时隙的不同物理资源块(Physical Resource Block，PRB)，这种跳频传输是基于PRB和VRB之间的资源映射关系进行的。
当然以上仅是对跳频传输进行举例说明，具体实现跳频传输的方式有很多种，不局限于上述任意一种。
在一个实施例中，根据所述多TTI传输所使用的传输信道，可以分为：多TTI的PUSCH传输和多 TTI的PDSCH传输。
在一个实施例中，如图3所示，本公开实施例提供一种无线通信方法，应用于终端中，所述方法包括：
S210：跳频发送多TTI的物理上行共享信道PUSCH传输。
多TTI的PUSCH传输为：在PUSCH上的多TTI传输。
在本公开实施例中，该多TTI的PUSCH传输之间采用跳频传输，如此多TTI的PUSCH传输是在不同的频带资源上进行的，从而提升了终端发射的频域分集增益。
在一个实施例中，如图4所示，本公开实施例提供一种无线通信方法，应用于终端中，所述方法包括：
S310：跳频接收多TTI的物理下行共享信道PDSCH传输。
在本公开实施例中，该多TTI的PDSCH传输之间采用跳频传输，如此多个TTI的PDSCH传输是在不同的频带资源上进行的，从而提升了终端接收的频域分集增益。
如图5所示，本公开实施例提供一种无线通信方法，应用于终端中，所述方法包括：
S410：接收所述多TTI传输的跳频传输指示，其中，所述跳频传输指示，至少指示是否跳频传输所述多TTI传输。
在本公开实施例中，基站会发送多TTI传输的跳频传输指示。如此，终端接收到跳频传输指示，就可以确定出基站会对多TTI传输进行跳频传输。
在另一个实施例中，基站也可以不下发跳频传输指示，例如，在通信协议或者预先预定中对某一类业务默认使用多TTI传输的跳频传输。
可以理解地，该多TTI传输的跳频传输指示，可以是在跳频传输多TTI传输之前接收的。
该跳频传输指示的携带信令可为基站下发的任意信令。
在一个实施例中，所述S410，包括：接收携带有所述跳频传输指示的高层信令.
此处的高层信令可为任意物理层以上的信令，典型的物理层信令可包括：DCI。举例来说，所述高层信令包括但不限于：无线资源控制(Radio Resource Control，RRC)信令，还可包括媒体访问控制(Media Access Control，MAC)信令。
在一个实施例中，所述S410还可包括：接收携带有所述跳频传输指示的物理下行控制信息DCI。
利用DCI携带所述跳频传输指示，具有传输效率高的特点。例如，DCI中的一个或多个比特携带有所述跳频传输指示。
在一个实施例中，若多TTI传输的跳频传输方式就默认仅有一种或者预设为了特定种，则基站和终端之间无需协商使用哪种跳频传输，则此时跳频传输指示可以单纯的指示是否进行跳频传输的控制指示。
在一个实施例中，响应于所述跳频传输具有多种跳频方式，所述跳频传输指示还指示所述多TTI传输的跳频方式。
例如，跳频方式有很多种，具体使用哪一种也可以由跳频传输指示来指示。
在一个实施例中，跳频传输指示中指示是否跳频传输的比特和指示跳频方式的比特可以是不同的比 特；在另一个实施例中，跳频传输指示中指示是否跳频传输的比特和指示跳频传输方式的比特是相同的比特。
例如，跳频传输指示具有两个比特，若两个比特的取值均为“0”则指示不进行跳频传输；若这两个比特的取值不全为“0”则指示进行跳频传输，并根据两个比特的取值具体确定跳频传输方式。例如，跳频传输方式有三种，若当前这两个比特的取值为“01”，则可认为指示进行多TTI传输的跳频传输，且采用跳频传输方式中的方式一。
各种跳频传输的跳频方式可以预先约定在协议中，也可以通过高层协议的接收，与基站事先协商。
在一个实施例中，携带有所述跳频传输指示的DCI为：调度所述多TTI传输的DCI。
在一个实施例中，发送所述跳频传输指示的DCI和所述调度所述多TTI传输的DCI可以不相同，在本公开实施例中一方面为了减少DCI的个数，减少终端盲解DCI所产生的功耗；另一方面，多TTI传输的调度和跳频传输指示用同一个DCI来完成，减少了终端将多TTI传输与对应跳频传输指示对应的过程，简化了终端操作。
本公开实施例提供一种无线通信方法，适用于终端中，包括：
S510：接收进行所述多TTI传输的物理下行控制信息DCI；
其中，所述DCI携带有频域资源分配信息，其中，所述频域资源分配信息，用于确定所述跳频传输的频域资源。
该频域资源分配信息的信息内容有多种，总之能够指示跳频传输的频域资源。
在一个实施例中，该频域资源分配信息包括：
频域资源信息，指示多TTI传输使用的频带；
跳频间隔，指示相邻两个TTI传输之间差异的频域带宽。
在另一个实施例中，，该频域资源分配信息包括：
频域资源索引序列；该序列内包括多个频域资源索引，相邻两个频域资源索引指示的频域资源在频域不相邻，进行跳频传输时，依次轮询使用频域资源索引序列中的各个频域资源索引指示的频域资源。
当然以上是对频域资源分配信息的举例，具体实现时不局限于此。
在一个实施例中，所述频域资源分配信息包括：
起始频域资源信息，指示所述跳频传输的首个TTI传输频域资源位置；
跳频方式信息，用于确定跳频传输的相邻两个TTI传输之间的频域偏移量或所述跳频传输的跳频图样。
不同的跳频方式可以有跳频方式信息指示。
示例性地，频域资源分配信息可指示起始频域资源位置，且直接携带指示跳频方式的跳频方式信息，供终端结合首个TTI传输的频域资源位置，确定出多TTI传输中每一个TTI所使用的跳频传输的频域资源位置。
在本公开实施例中，所述DCI携带了频域资源配置信息，则可以不用携带其他的指示多TTI传输所使用频域资源范围等信息，这样可以节省DCI的比特开销。在另一个实施例中，当然也可以携带多TTI传输所使用的频域资源范围的信息，这样减少跳频传输到预设带宽外的频域资源上。
如图7所示，本公开实施例提供一种无线通信方法，应用于基站中，所述方法包括：
S610：跳频传输多传输时间间隔TTI传输。
该无线通信方法应用于基站中，基站可以跳频发送多TTI传输和/或跳频接收多TTI传输。通过跳频传输多TTI传输，可以提高频域分集增益。
在一个实施例中，所述S610可包括：跳频接收多TTI的物理上行共享信道PUSCH传输；和/或，跳频发送多TTI的物理下行共享信道PDSCH传输。
在一个实施例中，所述方法还包括：
发送跳频传输指示，其中，所述跳频传输指示，至少指示是否跳频传输所述多TTI传输。
该跳频传输指示可以在进行调度多TTI传输之前进行，也可以是在调度多TTI传输之时同步进行。
在一个实施例中，所述发送跳频传输指示，包括：
通过高层信令下发所述跳频传输指示；此处的高层信令包括但不限于：RRC信令和/或MAC信令，此处的MAC信令包括但不限于MAC控制单元(Control Element，CE)；
或者，
通过下行控制信息DCI下发所述跳频传输指示。
示例性地，下发跳频传输指示的DCI和调度多TTI传输的DCI可以为同一个DCI也可以是不同的DCI，具体是否为同一个DCI可以根据当前的调度场景确定。
在一个实施例中，所述发送跳频传输指示，包括：
根据所述多TTI传输使用的频域资源，发送所述跳频传输指示。
若分配给多TTI传输使用的频域资源本身就是梳状的交织资源等分散频域资源，这种频域资源本身就具有提升频域增益的效果，则可以不用指示终端进行多TTI传输的跳频；若分配给这多TTI传输的频域资源为频域内一段连续分布的频域资源(即集中式频域资源)则可以通过跳频传输指示告知终端进行多TTI传输的跳频。
示例性地，所述根据所述多TTI传输使用的频域资源类型，发送所述跳频传输指示，包括：
响应于所述多TTI传输使用的频域资源为频域内的交织资源，发送指示不跳频传输的所述跳频传输指示；
和/或，
响应于所述多TTI传输使用的频域资源为集中式分布的频域资源，发送指示跳频传输的所述跳频传输指示。
在一个实施例中，响应于所述跳频传输的方式有多种，所述跳频传输指示还指示跳频传输的跳频方式；所述跳频传输指示所对应指示比特的取值，需要综合考虑是否跳频传输及在跳频传输时所使用的跳频方式，通过跳频传输指示，完成是否进行跳频传输和在跳频传输时所使用的跳频方式，具有比特开销小的特点。
在一个实施例中，如图8所示，所述方法还包括：
S600：发送所述多TTI传输的物理下行控制信息DCI；其中，所述DCI携带有频域资源分配信息，其中，所述频域资源分配信息，用于确定所述跳频传输的频域资源。
多TTI传输的调度信令是DCI，如此，在执行TTI传输之前下发DCI，在本公开实施例中，多TTI传输的DCI还携带有频域资源分配信息，该频域资源分配信息，可用于供终端确定出多TTI传输中每一个TTI传输所使用的频域资源。
示例性地，所述频域资源分配信息包括：
起始频域资源信息，指示所述跳频传输的首个TTI传输的频域资源位置；
跳频方式信息，用于确定跳频传输的相邻两个TTI传输之间的频域偏移量或所述跳频传输的跳频图样。
本公开实施例提出了为multi-TTI PDSCH调度下进行频域资源分配的方法。在该方法中，多个TTI之间的频域资源进行跳频，以获得频率分集增益。
多个TTI之间的跳频图样可以是协议固定的一种或者多种方案:例如在相邻的TTI之间进行BWP/4或者BWP/2跳频。
基站可以通过高层信令配置多个TTI之间进行跳频或者其他类型频域分配方式(其他类型的频域分配方式意味着不进行跳频，例如interlacing(交织)的频域资源分配方式)。
如果基站配置不进行跳频，在multi–TTI的PDSCH/PUSCH传输将占用相同的频域资源。如果基站配置了一种跳频方式，则在multi-TTI传输的调度中，可以直接应用该调度方式。如果基站配置了多种跳频方式，则可以在调度DCI中指示本次multi-TTI传输的调度究竟采用哪种跳频方式。
DCI中的频域资源分配信息域仅指示一种频域资源分配。
第一个TTI传输的频域资源按照DCI中指示的频域资源分配来占用，第二个及之后的TTI传输的频域资源，以DCI中指示的频域资源分配为基础，按照跳频图样进行跳频。
如图9所示，本公开实施例提供一种无线通信装置，应用于终端中，所述方法包括：
第一传输模块110，被配置为跳频传输多传输时间间隔TTI传输。
在一个实施例中，所述第一传输模块110可为程序模块；所述程序模块被被处理器执行后，能够实现跳频传输所述多TTI传输。
在另一个实施例中，所述第一传输模块110可为软硬结合模块；所述软硬结合模块包括但不限于各种可编程阵列；所述可编程阵列包括但不限于：现场可编程阵列和/或复杂可编程阵列。
在还有一些实施例中，所述第一传输模块110还包括：纯硬件模块；所述纯硬件模块包括但不限于：专用集成电路。
在一个实施例中，所述第一传输模块110，被配置为跳频发送多TTI的物理上行共享信道PUSCH传输；和/或，跳频接收多TTI的物理下行共享信道PDSCH传输。
在一个实施例中，所述装置还包括：
第一接收模块，被配置为接收所述多TTI传输的跳频传输指示，其中，所述跳频传输指示，至少指示是否跳频传输所述多TTI传输。
在一个实施例中，所述第一接收模块，被配置为接收携带有所述跳频传输指示的高层信令；或者，接收携带有所述跳频传输指示的物理下行控制信息DCI。
在一个实施例中，多种跳频方式响应于所述跳频传输具有多种跳频方式，所述跳频传输指示还指示 所述多TTI传输的跳频方式。
在一个实施例中，携带有所述跳频传输指示的DCI为：调度所述多个TTI传输的DCI。
在一个实施例中，所述装置还包括：
