Description

一种通信方法及装置

技术领域
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
在无线信号的传输过程中,需要保证数据在传输过程中足够的可靠性以及终端设备与基站在收发信号过程中的可管可控,因此在长期演进(Long Term Evolution,LTE)系统中,需要使用调度信令来对终端设备的上行传输进行调度,并且还会使用相应的应答消息对发送的消息进行是否成功接收的确认。
现有技术的通信方式,虽然在一定程度上提高了通信的可靠性,然而也增加了调度的时延,因此,基于免调度的上行传输方式成为目前第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的研究热点。这种传输方式,使终端设备可以在不需要上行调度的条件下,直接发送数据,从而减少了传输时延。然而在获得减少传输时延的条件下,会潜在地增加终端设备的上行传输的冲突。进一步地,基站需要对不同的免调度的上行传输进行应答消息的反馈,然而因为上行传输没有调度信息,基站如何反馈这些免调度传输的应答消息以不增加额外的传输时延和反馈开销是亟需解决的问题。

具体实施方式
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。
本申请提供一种通信方法及装置,用以解决现有技术中存在的免调度上行传输容易出现冲突的问题。其中,方法和装置是基于同一发明构思的,由于方法及装置解决问题的原理相似,因此装置与方法的实施可以相互参见,重复之处不再赘述。
本申请中所涉及的多个,是指两个或两个以上。
另外,需要理解的是,在本申请的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。
本申请实施例涉及的通信方法,主要针对终端设备与无线接入网中的网络设备进行数据传输的过程。所述终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile station,MS),终端设备(Terminal Equipment)、中继设备等等。所述网络设备可以包括各种在无线接入网中为终端设备提供通信功能的装置,例如可以是基站,该基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,基站的名称可能会有所不同,例如在长期演进(Long Term Evolution,LTE)网络中,称为演进的节点B(evolved NodeB,简称:eNB或者eNodeB),在第三代3G网络中,称为节点B(Node B)等等。
本申请实施例描述的技术可以适用于LTE系统,或其他采用各种无线接入技术的无线通信系统,例如采用码分多址,频分多址,时分多址,正交频分多址,单载波频分多址等接入技术的系统。此外,还可以适用于使用LTE系统后续的演进系统,如第五代5G系统等。为清楚起见,本申请实施例以下仅以LTE系统为例进行说明,所述终端设备为UE,所述网络设备为eNB。
需要说明的是,本申请实施例中的第一设备可以是终端设备,第二设备可以是网络设备或中继设备。
目前,基于免调度的上行传输方式使终端设备可以在不需要上行调度的条件下,直接发送数据,从而减少传输时延,然而在获得减少传输时延的条件下,会潜在地增加终端设备的上行传输的冲突,增加终端设备进行上行传输时资源选择的难度,因此,本申请实施例设计一种通信方法使用应答消息组对一组终端设备发送的数据进行是否成功接收的确认,这样能够减少终端设备上行传输的冲突概率、减少整个传输的时延以及应答消息的反馈开销。
下面结合附图对本申请提供的通信方案进行具体说明。
参见图1,为本申请提供的第一种通信方法的流程图。该方法包括:
步骤10:第二设备接收第一设备发送的数据。
需要说明的是,所述第一设备发送给所述第二设备的数据是所述第一设备采用免调度 的传输资源发送的。
一种可能的设计中,所述第一设备发送给所述第二设备的数据的帧结构中包括:参考信号和数据,具体的,图2A所示为传输方式为TDM时的帧结构示意图,图2B为传输方式为FDM时的帧结构示意图。
在上述图2A、图2B中,横轴方向表示时间,纵轴方向表示频域,参考信号(reference Signal,RS)在数据之前。
另一种可能的设计中,所述第一设备发送给所述第二设备的数据的帧结构中包括:参考信号、控制信息和数据。具体的,图2C所示为传输方式TDM时的帧结构示意图,图2D为传输方式FDM时的帧结构示意图。
在上述图2C、图2D中,横轴方向表示时间,纵轴方向表示频域,参考信号在数据和控制信息之前,数据和控制信息可以是在不同的时域资源上,如图2C所示,也可以是在相同的时域资源上,如图2D所示。
控制信息和数据可以在同一个信道中传输,也可以在不同的信道中传输。其中,控制信息中承载的信息包括:传输数据时占用的时频资源位置、传输数据时的MCS、当前传输的数据是新传还是重传、当前传输的数据的重传次数、以及一些其他可选的信令中的至少一种,例如:
1)功率余量指示信息,该信令可以用于指示第一设备当前是否还有预留功率,进一步可选的,如使用1比特,为“1”时表示还有预留功率,为“0”时表示无预留功率。其中,是否有预留功率是相对于第二设备发生的发射功率控制(Transmit Power Control,TPC)的调整值对应的步长而言的。有预留功率,表示剩余的功率不小于功率调整的步长,无预留功率,则表示剩余的功率小于功率调整的步长。这样,当第一设备的路损发生较大变化时,第一设备功率余量指示信息给第二设备,以便于第二设备能够根据这个功率余量指示信息值来确定相应的TPC的调整值。
2)是否有数据的指示信息,此时通过控制信息指示给第二设备,当前基于免调度的传输中是否有数据在发送。
可选的,第一设备在特定的传输区域内,可以只发送RS、控制与数据中的一种。例如,当第一设备可以只发送RS向第二设备指示它的数据传输结束或当前无数据传输。又如,第一设备可以使用RS和控制来向第二设备发送相应的控制或请求信息。又如,第一设备的上行传输资源与参数与上一次传输相同时,只发RS和数据。
这里RS可以用来供第二设备做第一设备是否存在的检测,以及可选的,用来标识不同的UE,或用来做信道估计使用。
可选的,上述各种例子中,每次传输的RS可以不同。这样可以减少第一设备侧不必要的消息传输,减少功率消耗,并使用不同的RS以便第二设备能够识别第一设备对应传输时的的各种配置信息。例如,使用不同的RS来指示:当前的免调度的传输中是否包含有上行控制信息,是否包含有上行数据信息,是否为初传等等。
步骤11:第二设备针对所述第一设备发送的数据生成应答消息组,所述应答消息组包含所述第二设备对所述至少一个第一设备发送的数据的应答消息。
其中,所述第二设备对所述第一设备发送数据的应答消息包括对所述第一设备所发送的控制信息或数据的检测的肯定或否定的应答信息。可选的,第二设备对所述第一设备发送数据的应答消息还包括:所述第一设备发送数据的传输资源或第一设备是否冲突的指示 信息,和/或,所述第一设备发送数据的传输资源或第一设备是否空闲的指示信息。
进一步的,一种可能的实施例中,根据第二设备对RS、控制信息、数据的检测状态可以定义第一设备发送的免调度的数据的可检测状态,具体的,可参阅表1所示。表1
RS的检测状态 控制信息的检测状态 数据的检测状态 应答消息
有效检测 正确检测 正确检测 确认(ACK)
有效检测 正确检测 不能正确检测 否认(NACK)
有效检测 不能正确检测 不能正确检测 冲突(collision)
不能检测 不能正确检测 不能正确检测 空闲(Idle)
需要说明的是,对数据和控制信息的“正确检测”意味着对数据或控制信息译码后循环冗余校验(Cyclic Redundancy Check CRC)校验正确。
对数据和控制信息的“不能正确检测”意味着对数据和/或控制信息译码后的CRC校验不正确。
对RS的“有效检测”是指检测到RS的能量超过预设阈值。
对RS的“不能检测”是指检测到RS的能量低于预设阈值。
通过使用上行免调度传输中的RS、控制信息和数据来精确地定义第二设备检测第一设备的状态,以便于第一设备收到相应状态后做出相应的传输调整,减少潜在地冲突。
可选的,对RS的检测还可以使用对控制信息和/或数据所在资源的能量值来指示,例如,可以用参考信号接收功率(Reference signal received power,RSRP),接收信号强度指示(Received Signal Strength Indicator,RSSI),参考信号接收质量(Reference Signal Received Quality,RSRQ)/信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)或信噪比(Signal Noise Ratiosnr,SNR)或干扰噪声比(Interference to Noise Ratio,INR)来表征能量值,具体的,可参阅表2所示。表2
能量检测状态 控制信息的检测状态 数据的检测状态 应答消息
有效检测 正确检测 正确检测 确认(ACK)
有效检测 正确检测 不能正确检测 否认(NACK)
有效检测 不能正确检测 不能正确检测 冲突(collision)
不能检测 不能正确检测 不能正确检测 空闲(Idle)
通过使用上行免调度传输中的RS、控制信息和数据来精确地定义第二设备检测第一设备的状态,以便于第一设备收到相应状态后做出相应的传输调整,减少潜在地冲突,同时使用检测的能量代替参考信号,便于第一设备侧做相应的测量。
一种可能的实施方式中,第二设备针对第一设备发送的免调度的数据的检测状态,还可以根据控制信息和数据的检测状态来指示。例如,各种具体的状态可参阅表3所示。表3
控制信息检测状态 数据的检测状态 应答消息
正确检测 正确检测 确认(ACK)
正确检测 不能正确检测 否认(NACK)
不能正确检测 不能正确检测 空闲(Idle)
这样,在第一设备没有传输RS时,使用上行免调度的控制信息和数据来精确地定义第二设备检测第一设备的状态,以便于第一设备收到相应状态后做出相应的传输调整,减少潜在地冲突。
步骤12:第二设备将所述应答消息组发送至所述第一设备。
其中,所述应答消息组包括所述第二设备接收到至少一个第一设备的数据的应答消息,所述应答消息组中的每个应答消息是针对至少一个第一设备发送的数据的应答,所述应答消息组中的每个应答消息由针对至少一个第一设备做出的应答消息使用逻辑与的方式生成的。
可选的,所述使用逻辑与的方式生成的所述应答消息对应相同的第一参数。
具体的,第二设备针对一组第一设备的应答消息发给一组第一设备,然后需要根据各个第一设备在做上行免调度传输时的传输参数来确定各个第一设备的应答消息在这个应答消息组内的位置。
进一步的,所述应答消息还包括第一设备发送的参考信号、控制信息、数据中的至少一种传输资源的索引信息。
步骤13:第一设备获取第一参数,所述第一参数用于确定所述第一设备发送的数据的应答消息。
一种可能的实施方式中,所述第一参数包括:所述第一设备发送的数据的应答消息在所述应答消息组中的位置的指示信息。
一种可能的实施方式中,所述第一参数包括:所述第一设备发送的数据的传输资源的指示信息,其中,所述传输资源包括以下资源中的至少一种:时域资源,频域资源,码域资源,空域资源。其中,码域资源包括序列的指示信息(如序列的根序列号),序列的循环移位的指示信息,序列的正交覆盖掩码的指示信息;空域资源包括使用的波束资源,预编码向量,空间所在的层或流。
图3所示为第二设备使用一组下行控制信息(Downlink Control Information,DCI)信令来向一组第一设备指示上行数据的应答消息。
如图3所示,第二设备为基站,第一设备为UE时,第二设备使用DCI信令来对一组第一设备来发送应答消息。如应答消息共包括对N个第一设备分别做应答的字段(N为不小于1的正整数),每个字段对应M比特的上行数据的应答消息(M为不小于1的正整数)。如图3所示,ACK/NACK 1为UE 1的应答消息,ACK/NACK 2为UE 2的应答消息,…,ACK/NACK N为UE N的应答消息。
进一步地,基站需要为第一设备确定DCI信令中的哪一部分是用来给哪个UE的上行数据的应答,下面给出几种可选的实施方式。
实施方式一:每个UE的ACK/NACK应答消息在整个DCI中的字段可以是基站通过RRC信令提前指示给UE的。例如指示DCI中的第1个位置是给UE1的应答消息,又如指示DCI中的第3个位置是给UE2的应答消息。这样,第二设备可以使用一个DCI对一组UE进行反馈,提前用信令明确地指示出各个UE的应答消息在应答消息组中的位置,从而减少了物理层信令的开销且能让UE一一对应到自己的应答消息。
实施方式二:每个UE的ACK/NACK应答消息在整个DCI中的字段的位置与UE的 上行传输资源相关联。例如:可以是与免调度的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)所使用的传输资源的资源索引来关联。如使用数据信道(如PUSCH)所使用的传输资源的最小索引、最大索引、最中间资源的索引或其他某个预定义传输位置的索引。同时还可以使用指示免调度的数据的控制信息所在的资源的索引来指示。例如,在免调度的传输资源中,共有N个子信道,每个子信道在频域上可以是一个物理资源块(Physical Resource Block,PRB),也可以是多个PRB,在时域上占用至少一个符号;每个子信道可以给不同的UE使用,或者说不同的UE可以在选择资源的时候必须以子信道为单位进行选择。图4所示为,使用不同的资源位置来关联应答消息在应答消息组内的位置。
如图4所示,UE1在子信道1上发送数据,UE2在子信道3上发送数据,UE3在子信道5、6、7上发送数据。而在基站侧检测到情况是:在子信道1上成功检测到数据,在子信道3上检测到有UE到达,但不能检测到数据,在子信道5上、6、7上检测到数据,但是译码发生错误,因此,基站将上述3个应答消息分别对应到子信道1,子信道3,子信道5,而其他的子信道因为基站没有检测到可靠的消息,则不做应答。
可选的,上述实施例中的子信道可以是UE发送数据的子信道,也可以是UE发送的控制信息或参考信号所在的子信道。
可选的,上述子信道可以是同一个时域资源上的不同频域子信道,还可以是不同时域资源上的频域子信道。
可选的,子信道与应答消息的指示信息可以在基站配置的信息中指示给UE。
这样,基站可以使用一个DCI对一组UE进行反馈,而且反馈时不需要指示每个UE的ID,不需要提前发送高层信令给UE来指示UE的应答消息在DCI应答消息组内的位置,从而减少了信令开销且能让UE一一对应到自己的应答消息。
在实施方式二下,存在第一设备的传输资源完全重叠或部分重叠的场景,图5所示为上述举例中出现UE3和UE4有部分资源重叠时的指示方法示意图。
如图5所示,UE3和UE4的传输资源在子信道5和子信道6上完全重叠,此时,若按实施方式二中的方法,单纯使用子信道5来指示应答消息时,UE3和UE4不能正确的区分出哪个应答消息是给自己的;或者基站都不能给UE3和UE4有区分地指示出对应的2个应答消息,进一步的,下面给出3中可能的解决上述冲突的实施方式:
第一种可能的实施方式中,在基站给出针对每个UE应答消息的字段中,同时包括传输资源的索引和参考信号的参数,这个参数包括序列的根序列号和/或序列的循环移位值和/或序列的正交覆盖掩码(OCC)。例如使用2比特指示ACK/NACK,使用另外的2比特来指示序列的循环移位值。这样,可以使用多种传输参数来联合地指示不重叠UE的应答消息的位置。
例如,UE3使用循环移位是4种中的第1种,UE3使用循环移位是4种中的第2种,则基站可以分别使用00指示对UE3的应答,01是对UE2的应答。
同样地,例如,UE3使用4种预定义的根序列号的序列中的第1种,UE3使用循环移位是4种预定义的根序列号中的第2种,则基站可以分别使用00指示对UE3的应答,01是对UE2的应答。
第二种可能的实施方式中,联合使用数据的位置索引和控制信息的位置索引来指示应答消息对应的UE。这样,可以使用多种传输参数来联合地指示不重叠UE的应答消息的位 置。
可选地,为了减少反馈消息的开销,可以将控制消息在资源池中的位置分成M个部分,如4、8、10个部分。基站可以使用log 2(M)比特来指示控制消息所在的频域位置。例如M=4时,基站可以再使用2比特可以指示不同控制信道以及不同数据信道位置对应的应答消息。
进一步的,上述在解决用户资源重叠时的方法使用的DCI格式与无重叠的DCI格式不同。即不重叠时使用DCI格式1,重叠时使用DCI格式2。这里DCI的格式包括:DCI类型,DCI大小,DCI使用的CRC掩码(如使用的无线网络临时标识(RNTI Radio Network Tempory Identity,RNTI)),DCI使用的解调参考信号。
第三种可能的实施方式中:使用一个应答消息来给多个UE做免调度传输的应答。例如一个应答消息对M个UE同时做ACK/NACK应答。
进一步可选的,当使用一个应答消息来给多个UE做应答的反馈时,这里的多个UE的第一参数的取值相同。即相当于,多个UE的传输资源不能相互区分或有部分的重叠,使用多一个应答消息来给多个UE做应答的反馈,不仅可以减少反馈开销,还能解决多个UE的资源冲突或部分重叠的问题。
如上面的举例中,有2个UE重叠时(相当于M=2),如果这2个UE都被成功的检测,则发送ACK,如果这2个UE有任意一个或者两个都没有成功被检测到,则发送NACK。UE3和UE4在收到ACK时,则可以继续发送新的包;UE3和UE4在同时收到NACK,则2个UE选择与初重不一样的资源重新发送。采用上述方法,能够减少反馈开销,对用户数量多且时延不敏感的业务有很大帮助。
实施方式三:每个UE的ACK/NACK在整个DCI中字段的位置仅与UE的参考信号的参数相关联。例如,与实施方式二类似,可以只使用参考信号的参数(根序列号、循环移位值(CS)、正交覆盖掩码(OCC))等来关联指示不同UE的应答消息在应答消息组内的位置。这样,可以使用多种传输参数来联合地指示不重叠UE的应答消息的位置。
进一步可选的,使用共用的(common)或组相关的无线网络临时标识(RNTI Radio Network Tempory Identity,RNTI)或是common或是组相关的DCI的搜索空间来传输ACK/NACK的应答消息,此时,上述ACK/NACK的应答消息对应一组UE,使用一个与这一组UE相关联的RNTI来指示。这种方式中通过使用组相关的公共的RNTI或搜索空间,能够减少UE的盲检次数,降低UE检测的复杂度。
由此而知,把一组UE的应答消息放在一个DCI消息中,使用传输资源位置、参考信号参数来对应不同UE传输的ACK/NACK的应答消息在这个DCI应答消息组内的位置,从而可以一一地对各个UE的数据传输做出相应的应答。
步骤14:第一设备根据所述第一参数从所述应答消息组中确定所述第一设备发送的数据的应答消息。
需要说明的是,所述应答消息组在公共的控制信息中传输,当所述第一设备在所述公共的控制信息中没有检测到所述应该消息时,所述第一设备在第一设备特定的控制信息中检测所述应答消息。
进一步的,所述应答消息中还包括传输模式指示信息,传输资源指示信息中的至少一种。
参见图6,为本申请提供的第二种通信方法的流程图。该方法包括:
步骤61:第一设备获取第一控制信息,所述第一控制信息包括:传输模式指示信息,传输资源指示信息中的至少一种。
其中,所述传输模式包括:基于调度的传输模式或免调度的传输模式,基于竞争的免调度的传输模式或基于预配置的免调度的传输模式,基于单个资源的传输模式或基于多个资源的传输模式。
进一步的,第一设备在执行步骤61之前,第一设备向第二设备发送第二数据和/或第二控制信息,所述第二控制信息用于指示所述第二数据的传输格式。
此时,所述传输资源指示信息用于:指示所述第一数据发送时使用的传输资源是否在第二数据发送时仍可以使用;或者指示所述第二数据发送时使用的传输资源是否与第一数据发送时的传输资源相同。
可选的,第二控制信息与所述第二数据在同一个信道中传输,或在不同的信道中传输。
其中,所述第二控制信息包括以下信息中的至少一种:当前的传输次数;所述第一设备是否收到应答的指示信息或第一设备当前的重传类型,如基于NACK的重传,或基于未收到任何响应的重传;所述第一设备的发射功率是否可以减少的指示信息。
在高可靠低时延(URLLC)的场景下,对下行应答和上行传输都有很高的可靠性的要求;如果基站发了ACK,但是UE没有收到,仍在发重传,如果基站没有意识到是这种传输场景,基站且对这个消息检测发生了错误,则基站会发NACK。反之如果基站知道了当前的传输是UE没有收到任何应答的重传,则基站就不用去检测后面的数据包,而是直接去检查上一次UE发的重传包是否接收正确。如果是,则基站直接反馈ACK,图7A所示为基站与UE间的应答过程示意图。
如图7A所示,UE1在发重传1的时候,基站收到后发一个ACK,但是UE可能并未收到这个ACK消息,所以继续发重传2并向基站指示当前的重传是未收到任何应答的重传,基站在控制信息中检测到了这个信息,基站则不用去检测重传2的数据,直接通过检查上次的重传1是否正确接收便可以直接回复ACK。这样减少了处理时延,可潜在的减少不必要的信息传输。
可选的,所述第二控制信息还包括:传输模式的请求信息,用于直接请求某种传输模式,或者请求进行传输模式的切换。
具体的,传输模式包括以下传输模式中的任意两种:
基于调度的传输模式和基于免调度的传输模式,或者
基于竞争的免调度的传输模式和基于预配置的免调度的传输模式,或者
基于多个资源的传输模式和基于单个资源的传输模式。
多个资源的传输模式和单个资源传输模式之间进行切换的请求信息。
可选的,第一设备可以根据自己的业务类型或业务类型的变化向第二设备发送传输模式的请求信息。
这样,当第一设备的业务类型发生变化时,可以主动请求相应的传输模式,以便于传输模式与业务更好地匹配,提高了数据传输的效率。
进一步的,当所述第一设备的业务的优先级高于特定的门限时,第一设备发送所述传输模式的请求信息。
具体的,所述第一设备获取第一控制信息时,根据不同的控制信息格式或者控制信息传输参数来获取所述第一控制信息。
其中,所述控制信息传输参数包括以下信息中的任意一种:控制信息传输时使用的CRC掩码、加扰序列的生成参数,如生成序列的初始值、解调参考信号(DMRS)的生成参数,如序列标识、序列循环移位值、序列的正交覆盖掩码(Orthogonal Cover Code,OCC)、控制信道的格式,如一级调度的控制信道,或二级调度的控制信道。
步骤62:第一设备根据所述第一控制信息确定第一数据的传输资源。
具体的,所述根据所述第一控制信息确定第一数据的传输资源时,根据所述传输模式指示信息确定所述第一数据的传输资源,其中,不同的传输模式对应不同的传输资源或传输资源池,需要说明的是,这里的资源池为一组传输资源的集合。
当所述确定的传输资源为多个资源的传输模式配置的资源时,所述第一设备还需要获取多个资源传输模式的传输参数指示信息。
其中,所述多个资源传输模式的传输参数指示信息包括以下中的至少一种:每组多资源传输中子资源的数量、每组多资源传输中每个子资源上的跳频参数、每组多资源传输中子资源的调制方式、每组多资源传输中子资源的编码方式、每组多资源传输中每个子资源上参考信号配置参数。这里的参考信号配置参数包括以下中的至少一种:生成的参考信号序列的初始值、生成的参考信号序列的标识、生成的参考信号序列循环移位值、生成的参考信号序列的OCC。
可选的,当所述确定的传输资源为多个资源的传输模式配置的资源时,可以进行以多个资源的传输模式的重传。
进一步可选的,当所述确定的传输资源为多个资源的传输模式配置的资源时,多个资源传输模式的初传时的传输参数与重传时的传输参数配置不同。多资源的传输模式,是指在第一数据的某次传输时,至少使用2个子传输资源。其中每个子传输资源的传输参数,如:跳频参数、调制方式、编码方式、参考信号配置参数、所占用的时频资源等,是可以独立配置的。
如图7B所示,第一数据的初传、第一次重传和第二次重传时使用的多资源中各个子资源的数量分别为2,3,4。进一步的,多个资源传输模式的新传与重传或不同的重传间的传输参数可以配置成不同。这样能够使不同的多个资源传输模式的传输参数获得在不同的重传间的分集增益,从而提高系统的性能。
步骤63:第一设备在所述确定的传输资源上发送所述第一数据。
需要说明的是,第二种通信方法可以与第一种通信方法中的第二设备使用共用的DCI来反馈应答消息进行联合使用。比如,在第一设备进行数据初传时使用第一种通信方法中的用户共用的DCI来反馈应答消息,在第一设备进行数据重传时使用用户特定的DCI来反馈应答消息。或者对没有冲突的第一设备,第二设备使用第一种通信方法的用户共用的DCI来反馈应答消息;对有冲突的第一设备,第二设备使用用户特定的DCI来反馈应答消息。对于第一设备而言,需要先检测共用的DCI,如果在共用的DCI中没有检测到自己的应答消息,则需要在用户特定的DCI中检测自己的应答消息。
或者,可选的,对应于第一设备侧,第二设备侧有:开始只配置了第一设备公共的资源和第一设备共用的RNTI,当第一设备一直没有收到应答消息时,第一设备可以发起基于调度的连接,请求特定的RNTI。第二设备则基于第一设备特定的RNTI向第一设备发送应答消息,一旦第一设备获得特定的RNTI,则第一设备需要先检测共用的RNTI,然后再检测第一设备特定的RNTI。
这样,第一设备可以在不同的DCI类型之间进行切换,尽可能同时获得两种DCI的好处,使得系统性能达到最优。
当使用第二设备使用特定的RNTI来对每个第一设备的上行数据做应答时,应答消息包括以下信息中的一种或多种组合:
1)应答消息ACK/NACK;
2)第一设备的ID或第一设备特定的RNTI;
3)调制与编码方案(Modulation and Coding Scheme,MCS)或MCS的调整值;
4)TPC或TPC的调整值;
5)定时(Timing Advance,TA)值或定时提前调整值;
6)传输模式指示信息。针对不同的业务、不同的第一设备的类型和不同的第一设备的能力使用不同的传输模式,有利于系统为不同的需求提供差异化的服务,更好地满足各类业务的需求。
具体的,传输模式包括以下传输模式中的任意两种:
基于调度的传输模式和基于免调度的传输模式,或者
基于竞争的免调度的传输模式和基于预配置的免调度的传输模式,或者
基于多个资源的传输模式和基于单个资源的传输模式。
此外,传输模式指示信息可以使用显式的信息来指示,如在DCI中定义的字段;可选的,也可以使用隐式的信息来指示,例如DCI使用的DMRS的参数,与模式相关的RNTI等信息来指示。
对于不同的传输模式,不同的grant-free的传输模式可以使用不同类型的资源或资源池。
可选的,对于不同的传输模式,第一设备在上行免调度传输时使用的RS可以不同。或者第一设备按不同的业务的优先级,选择使用基于免竞争的传输模式或者使用基于预配置的传输模式。
7)传输资源指示信息。当第一设备上次传输数据使用的传输资源不够好时,可以让第一设备有机会了解使用的传输资源的状态,及时调整传输资源,提高系统性能。
传输资源指示信息可以通过以下信息进行指示:
指派的资源位置(Resource allocation,RA),此时,第二设备用信令从资源池中指示哪些时、频资源可以使用。
或者在资源池中限制的RA,此时,第二设备用信令从资源池中指示哪些时、频资源不可以使用。
或者指示当前资源是否可用,例如:使用1比特来指示,“1”建议使用上次的传输资源;“0”建议更换上次的传输资源。
或者指示是否使用跳频的指示信息,即指示下次传输的频域资源与上次传输的频域资源是否相同;或者是跳频方式的指示信息,例如,使用1比特来指示,“1”表示使用跳频方式一,“0”表示使用跳频方式二。
采用上述通信方法,利用第一控制信息能够精确地对第一设备的传输参数进行指示,提高通信的效率和性能,特别是对有传输冲突的第一设备能够进行更有效的反馈和调度。
参见图8,为本申请提供的第三种通信方法的流程图。该方法包括:

其中,所述停止使用免调度的资源进行传输的指示信息中包括:停止当前传输的配置参数,其中所述配置参数包括以下信息中的任意一种:中止传输的定时器的起止时间;中止传输的时间间隔。
进一步的,第一设备在步骤81执行之前,还需要执行:向第二设备发送第二控制信息,所述第二控制信息用于指示所述第一设备的业务的优先级或业务类型。

具体的,第二设备预定义了一部分用于免调度的传输发生异常时的预留资源;可选的,这个预留资源可以是在系统定义的预留资源中;正常传输时,第一设备在grant-free的传输资源上传输数据,当数据传输发生异常时,第一设备则在预留资源上传输。
可选的,第一设备通过上行控制信道向第一设二比指示它的grant-free的数据传输使用了grant-free的预留资源,需要说明的是,业务优先级高的第一设备或处于切换状态下的第一设备可以使用grant-free的预留资源。

可选的,所述第一设备接收所述第二设备发送的从预留资源切换到免调度资源的指示信息。
采用上述通信方法,第一设备在免调度传输发生异常时,进行数据传输方式或传输资源的切换,以便于提高第一设备在异常情况下针对数据传输的处理能力,减少异常条件下的数据传输时延。
参见图11,为本申请提供的第六种通信方法的流程图。该方法包括:
步骤111:第一设备获取第一控制信息。
可选的,所述第一控制信息是上行控制信息(Uplink Control Information,UCI)。
步骤112:所述第一设备使用免调度的传输资源向基站发送所述第一控制信息。
进一步的,在步骤112执行之前,即所述第一设备使用免调度的传输资源向基站发送所述第一控制信息之前,所述第一设备还需要执行:接收所述基站发送的上报所述第一控制信息的指示信息。
这个指示信息可以承载于下行的控制信息中,或者也可以承载于对上行免调度的数据的应答消息中。
具体的,所述第一控制信息包括以下中的至少一种:信道状态信息(Channel State  Information,CSI);混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)应答信息;调度请求(Scheduling Request,SR)。
其中,所述信道状态信息包括以下中的至少一种:
信号质量信息,如:SNR,SINR,CQI,RSSI,RSRP,RSRQ、预编码指示信息(Precoding Matrix Indicaton,PMI)、波束指示信息(Beam Indicaton,BI)、秩指示信息(Rank Indication,RI)。
具体的,所述使用免调度的传输资源向基站发送所述第一控制信息包括以下两种情形:
情形一:使用免调度的上行数据信道向基站发送所述第一控制信息。

具体地,当第一设备通过上行免调度的上行控制信道发送CSI时,CSI的全部或一部分消息承载于上行控制信道,并且使用上行控制信道的预留字段或者当上行控制信道中在当前传输时无效或不使用的字段中传输,如重传时,如果MCS没变且传输资源也没变,则第一设备只需要在上行控制信道中指示重传次数,而其他字段如:指示MCS、传输时使用的时频资源的字段则可以用来承载CSI,在这种实施方式下,第一设备需要向基站指示此时的部分字段用于承载CSI,由于使用控制信道来传输CSI,提高了资源的利用率和传输效率,降低了CSI的反馈时延。
这样,能够减少第一控制信息在反馈时的不必要的基于调度的传输,充分利用免调度的传输,提高传输效率。
情形三:使用基于调度的资源向基站发送第一控制信息的第一部分,如HARQ应答消息和/或SR,使用免调度的资源向基站发送第一控制信息的第二部分,如第一控制信息中的其他信息。
情形四:使用免调度的上行载波发送所述基于调度的上行载波对应的下行载波的第一控制信息,或者,使用基于调度的上行载波发送所述免调度上行载波对应的下行载波的第一控制信息。
具体的,一种可能的实施方式中,可以使用免调度的资源(载波,载波上的各种信道)发送上行调度载波对应的下行载波的CSI。可选的,当有多个蜂窝链路的载波时,第一设备接收基站发送的CSI的请求消息,并且基站向第一设备指示用于发送CSI的基于免调度的上行载波的索引。可选的,第一设备在基于免调度的载波上发送基于调度载波上的CSI 的消息,并指示所测量的CSI所在载波的索引。这里使用基于多载波连接的CSI反馈方法,提供载波间的资源共用,提高某种类型载波上的传输效率,降低了CSI的反馈时延。
具体的,另一种可能的实施方式中,可以用调度资源(载波,载波上的各种信道)发送上行免调度载波对应的下行载波的CSI。当有多个蜂窝链路的载波时,在免调度的载波上,第一设备接收基站发送CSI的请求消息,并且基站向第一设备指示用于发送CSI的基于调度的上行载波的索引。可选的,第一设备在基于调度的载波上发送免调度载波上的CSI的消息,并指示所测量的CSI所在载波的索引。这里使用基于多载波连接的CSI反馈方法,提供载波间的资源共用,提高某种类型载波上的传输效率,降低了CSI的反馈时延。
可选的,在通过免调度的资源发送上行CSI时,需要关闭基于调度的上行控制信道的传输。此时,所述第一设备使用免调度的上行数据信道向基站发送所述第一控制信息时,接收基站发送的所述第一设备关闭基于调度的上行控制信道传输的指示信息。
可选的,第一设备在通过免调度的资源发送上行CSI时,没有基于调度的上行传输和/或没有基于调度的下行传输。
可选的,对于下行数据传输的应答ACK/NACK使用基于调度的资源传输,而对下行CSI的反馈则使用免调度的资源传输,这里免调度的资源包括:控制信道,数据信道,载波。
可选的,使用调度资源传输免调度的CSI,或者使用免调度的资源传输调度的CSI。
采用上述通信方法,可以只使用一种调度方式把各种不同类型的载波上的第一控制信息反馈给第一设备,从而减少了并行同时存在的反馈信道数,减少了系统开销以及第一设备侧的发射功率。
需要说明的是,上述实施例中的通信方法可以单独应用,也可以组合使用。第二设备(或基站)发送的消息可以组合使用;第一设备(或终端设备)发送的消息可以组合使用。
