Description

时隙格式指示方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种时隙格式指示方法及装置。
背景技术
时隙格式用以指示如何使用单个时隙中的每个符号，比如定义哪些符号用于上行链路，哪些符号用于下行链路；通过应用时隙格式或按顺序组合不同的时隙格式，可以实现对多个时隙的各种不同类型的调度。
在新的无线技术(NR，New Radio)授权频谱中，时隙格式支持无线资源控制(RRC，Radio Resource Control)信令+下行控制信息(DCI，Downlink Control Information)信令配置。RRC信令给出多个时隙格式组合标识(slotformatcombinationID)与其相对应的时隙格式组合(slot format combination)，比如slotformatcombinationID为#0时，表示这个时隙格式组合里面包含了X个时隙格式(slot format)，即这X个时隙格式中每个时隙格式对应的编号；比如X为3，这3个时隙格式对应的编号分别为format#1，format#3，format#6。目前规定X的值最大为256个，而slotformatcombinationID最大值511，基站使用RRC信令告知终端多个slotformatcombinationID与之对应的slot format combination之后，再使用DCI信令来指示其中的slotformatcombinationID，从而终端就获知了多个时隙的时隙格式。

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。
相关技术中，在LAA中，时隙格式指示(SFI，slot format indication)的DCI信令是通过主小区(PCell，primary cell)的用户群(Group common)DCI来发送的；DCI信令中有多个slotformatcombinationID域，每个域对应基站的一个成员载波(CC，Component Carrier)，即某个用户设备(UE)对应的一个服务小区(serving cell)，例如，假设基站一共有5个CC，UE#1被配置有CC#0即SCell#0，CC#1即SCell#1；UE#2被配置有CC#3即SCell#0，CC#4即SCell#1；那么基站发送的用于指示SFI的一共有五个slotformatcombinationID，每个域对应一个CC，基站需要告知UE#1，SCell#0的SFI对应第一个slotformatcombinationID域的指示，SCell#1的SFI对应第二个slotformatcombinationID域的指示；基站需要告知UE#2，SCell#0的SFI对应第四个slotformatcombinationID域的指示，SCell#1的SFI对应第五个slotformatcombinationID域的指示；基站通过一个groupcommon DCI最多可发送所有CC的SFI，各UE根据被配置的SCell去相应位置获取自身Scell的SFI信息；在LAA中每个CC的最大带宽为20MHz，而先听后说(LBT，Listen Before Talk)的带宽单元(BW unit)正好为20MHz，所以一个CC上只有一个LBT BW unit。然而，在NR中，一个CC例如可以为400MHz，而每个UE在每个CC上被配置多个部分带宽(BWP，Bandwidth Part)，不同的BWP包含的带宽或频域位置至少有一样不同。目前，每个UE在每个CC上只有一个激活(active)BWP，然后基站在该BWP上进行LBT后，再在LBT检测信道空闲的该激活BWP的带宽上的一部分或全部进行下行发送，而LBT的信道检测带宽单元也可以为20MHz，是可以小于BWP带宽的。那么，基站在LBT检测之后，需要告知UE哪些LBT的信道检测带宽单元上信道空闲，且其SFI格式指示如何定义及实现是亟待解决的技术问题。
为了解决上述问题，本发明实施例提供了一种时隙格式指示方法，应用于基站，方法包括：在与终端对应的目标服务小区上的激活BWP上进行LBT之后，确定激活BWP所包括的各个LBT BW unit中对应的信道空闲的目标LBT BW unit；向终端发送DCI，其中，DCI中包括 目标LBT BW unit的SFI。本发明实施例提供的时隙格式指示方法，通过基于LBT信道检测带宽单元来指示SFI，并告知终端哪些LBT BW unit对应的信道空闲，使终端获得明确的SFI与适用的LBT BW unit，实现时隙格式的明确指示，能够提高系统的可靠性。
参见图1示出的本发明实施例中时隙格式指示方法的一个可选的应用场景；图1所示的应用场景中涉及：终端11、终端12、蜂窝网络的基站13、及核心网14；其中，蜂窝网络可以是4G或5G网络等；终端11和终端12均与基站13建立通信连接，终端11、终端12例如可以包括智能手机、平板电脑、台式机、笔记本电脑、无人机或穿戴式设备(如手环、智能眼镜等)等。图1中示出的应用场景仅是本发明实施例记载的技术方案的一个可能的应用场景示例，其他应用场景可以包括图1未涉及的设备和网络。基于上述分析，提出以下各具体实施例。
图2是根据一示例性实施例示出的一种时隙格式指示方法的流程图。本发明实施例中时隙格式指示方法的执行主体可以为基站。如图2所示，该方法包括以下步骤201-202：
在步骤201中，在与终端对应的目标服务小区上的激活BWP上进行LBT之后，确定激活BWP所包括的各个LBT BW unit中对应的信道空闲的目标LBT BW unit。
示例的，基站将与终端对应的目标服务小区上的带宽分为N个LBT信道检测带宽单元，比如目标服务小区带宽为100MHz，LBT信道检测带宽单元为20MHz，则分为五个LBT BW Unit，这五个LBT BW Unit的编号分别为LBT BW unit#0，LBT BW unit#1，LBT BW unit#2，LBT BW unit#3，LBT BW unit#4。基站通过给终端配置BWP，使得终端能够获知自己的激活BWP是包含哪些LBT BW unit的，比如UE#1的激活BWP包含LBT BW unit#0、LBT BW unit#1及LBT BW unit#2，UE#2的激活BWP包含LBT BW unit#2、LBT BW unit#3及LBT BW unit#4。
基站在与终端对应的目标服务小区上的激活BWP上进行LBT之后，将激活BWP所包括的各个LBT BW unit中对应的信道空闲的LBT BW unit，确定为目标LBT BW unit。
在步骤202中，向终端发送DCI，其中，DCI中包括目标LBT BW unit的SFI。
示例的，基站在与终端对应的目标服务小区上的激活BWP上进行LBT之后，告知终端哪些LBT BW unit对应的信道空闲，以及信道空闲的LBT BW unit的SFI。终端接收到基站发送的DCI之后，根据DCI确定目标LBT BW unit的编号和SFI。随后，基站在一个或多个信道空闲的LBT BW unit上向终端发送下行数据；终端通过激活BWP中的信道空闲的LBT BW unit，接收下行数据。
示例的，基站在与终端对应的目标服务小区上的激活BWP上进行LBT之前，向终端发送指示消息；指示消息用于表征在与终端对应的目标服务小区上的激活BWP所包括的各个LBT BW unit的带宽位置和编号。可选的，该指示消息可以是基站给终端配置BWP的BWP配置消息。
采用本发明实施例提供的技术方案，通过基于LBT信道检测带宽单元来指示SFI，并告知终端哪些LBT BW unit对应的信道空闲，使终端获得明确的SFI与适用的LBT BW unit，实现时隙格式的明确指示，能够提高系统的可靠性。
图3是根据一示例性实施例示出的一种时隙格式指示方法的流程图。本发明实施例中时 隙格式指示方法的执行主体可以为基站和终端。如图3所示，该方法包括以下步骤301-304，其中，本实施例没有详细说明的部分可以参照图2实施例的对应说明：
在步骤301中，基站在与终端对应的目标服务小区上的激活BWP上进行LBT之后，确定激活BWP所包括的各个LBT BW unit中对应的信道空闲的目标LBT BW unit。
在步骤302中，基站在目标LBT BW unit所包括的至少一个LBT BW unit上向终端重复发送DCI；其中，DCI中包括信道空闲指示信息和目标服务小区上所有信道空闲的LBT BW unit的SFI，信道空闲指示信息用于表征目标服务小区上所有LBT BW unit各自对应的信道是否空闲。
示例的，所有信道空闲的LBT BWU上的SFI可以相同或者不同。在目标服务小区上的所有LBT BW unit上的SFI格式一样时，则目标服务小区的slotformatcombinationID域只需要指示一种SFI，同时，再占用一些bit，所占用的bit数为目标服务小区上所有LBT BW unit的个数，即每个LBT BW unit对应一个bit；例如，若该bit显示1，则表示该LBT BW unit对应的信道空闲，且SFI同slotformatcombinationID指示；若该bit显示0，则表示该LBT BW unit对应的信道忙。在目标服务小区上的所有LBT BW unit上的SFI格式不一样时，则目标服务小区的slotformatcombinationID域需要指示N种SFI，N为目标服务小区上所有信道空闲的LBT BW unit的数目。即每个信道空闲的LBT BW unit对应一种SFI，比如N个信道空闲的LBT BW unit中的第M个LBT BW unit对应N个SFI中的第M个SFI。同时，再占用一些bit，所占用的bit数为目标服务小区上所有LBT BW unit的个数，即每个LBT BW unit对应一个bit；例如，若该bit显示1，则表示该LBT BW unit对应的信道空闲；若该bit显示0，则表示该LBT BW unit对应的信道忙。
基站向终端发送的DCI指示了目标服务小区上所有信道空闲的LBT BW unit的SFI，DCI可以在所有信道检测空闲的LBT BW unit上发，或者，只在所有信道检测空闲的LBT BW unit中的一部分LBT BW unit上发送；在各LBT BW unit上预先配置了发送DCI的控制资源集合(CORESET，control resource set)。这种情况下，终端只要检测到其中一个LBT BW unit上的DCI即可获知目标服务小区上所有LBT BW unit的信道空闲情况以及SFI。
在步骤303中，终端在与终端对应的目标服务小区上的激活BWP所包括的至少一个LBT BW unit上检测DCI。
在步骤304中，终端当在激活BWP所包括的任一个LBT BW unit上检测到DCI时，根据DCI中包括的信道空闲指示信息和所述目标服务小区上所有信道空闲的LBT BW unit的SFI，确定所述激活BWP所包括的各个LBT BW unit中对应的信道空闲的LBT BW unit的编号和SFI为所述目标LBT BW Unit的编号和SFI。
示例的，这种情况下，终端可以不需要再去检测其它LBT BW unit上发送的所述DCI了。
采用本发明实施例提供的技术方案，通过基站在一个或多个信道检测空闲的LBT信道检测带宽单元上发送指示SFI的DCI信令，该DCI信令上携带用于表征目标服务小区上所有LBT BW unit各自对应的信道是否空闲的信道空闲指示信息，使终端获得明确的SFI与适用的LBT  BW unit，实现时隙格式的明确指示，能够提高系统的可靠性。
图4是根据一示例性实施例示出的一种时隙格式指示方法的流程图。本发明实施例中时隙格式指示方法的执行主体可以为基站和终端。如图4所示，该方法包括以下步骤401-404，其中，本实施例没有详细说明的部分可以参照图2实施例的对应说明：
在步骤401中，基站在与终端对应的目标服务小区上的激活BWP上进行LBT之后，确定激活BWP所包括的各个LBT BW unit中对应的信道空闲的目标LBT BW unit。
在步骤402中，基站在目标LBT BW unit所包括的每个LBT BW unit上分别向终端发送与对应的所述DCI；其中，所述对应的所述DCI中包括承载该对应的所述DCI的LBT BW unit的SFI。
示例的，所有信道空闲的LBT BWU上的SFI可以相同或者不同。由于所述DCI只需要指示承载该DCI的LBT BW unit上的SFI，所以在目标服务小区上的所有LBT BW unit上只需要指示一种SFI，则所述DCI中只需要指示SFI，可以不指示目标服务小区上哪些LBT BW unit对应的信道空闲，因为在这个LBT BW unit上发送了DCI即表示该LBT BW unit信道空闲，且使用该LBT BW unit检测到的DCI所指示的SFI。DCI必须在所有信道检测空闲的LBT BW unit上发送；在各LBT BW unit上预先配置了发送DCI的CORESET。这种情况下，终端只要能够检测到该DCI，则终端获知该LBT BW unit被检测到信道空闲，同时也能获得DCI中指示的该LBT BW unit的SFI。
在步骤403中，终端在与终端对应的目标服务小区上的激活BWP所包括的每一个LBT BW unit上检测DCI。
在步骤404中，终端当在激活BWP所包括的任一个LBT BW unit上检测到DCI时，确定检测到DCI的LBT BW unit的编号为所述目标LBT BW Unit的编号，确定所述DCI中包括的SFI为所述目标LBT BW Unit的SFI；其中，DCI中包括检测到DCI的LBT BW unit的SFI。
这种情况下，由于每个LBT BW unit上只发送了自身带宽上的SFI，所以终端需要继续检测其它LBT BW unit上的所述DCI，进一步获取其它LBT BW unit的SFI。
采用本发明实施例提供的技术方案，通过基站在与终端对应的目标服务小区上的激活BWP所包括的每个信道检测空闲的LBT信道检测带宽单元上发送指示SFI的DCI信令，终端若在激活BWP所包括的某个LBT信道检测带宽单元上检测到DCI时，则检测到DCI的LBT BW unit对应的信道空闲，否则不空闲，从而使得终端获得明确的SFI与适用的LBT BW unit，实现时隙格式的明确指示，能够提高系统的可靠性。
在一种实施例中，当目标服务小区上所有LBT BW unit的SFI不完全相同时，DCI中包括目标LBT BW unit所包括的至少一个LBT BW unit的SFI；基站在目标LBT BW unit所包括的每一个LBT BW unit上向终端重复发送DCI。终端在与终端对应的目标服务小区上的激活BWP所包括的至少一个LBT BW unit上检测DCI；当在激活BWP所包括的任一个LBT BW unit上检测到DCI时，根据DCI中包括的信道空闲指示信息和所述目标服务小区上所有信道空闲的LBT BW unit的SFI，确定所述激活BWP所包括的各个LBT BW unit中对应的信道空闲的 LBT BW unit的编号和SFI为所述目标LBT BW Unit的编号和SFI。
图5是根据一示例性实施例示出的一种时隙格式指示方法的流程图。本发明实施例中时隙格式指示方法的执行主体可以为终端。如图5所示，该方法包括以下步骤501-502：
在步骤501中，接收基站发送的DCI，其中，DCI中包括目标LBT BW unit的SFI，目标LBT BW unit包括与终端对应的目标服务小区上的激活BWP所包括的各个LBT BW unit中对应的信道空闲的LBT BW unit。
示例的，基站在与终端对应的目标服务小区上的激活BWP上进行LBT之后，确定激活BWP所包括的各个LBT BW unit中对应的信道空闲的目标LBT BW unit；基站向终端发送下行控制信息DCI，其中，DCI中包括目标LBT BW unit的时隙格式指示SFI。终端接收基站发送的DCI。
在步骤502中，根据DCI，确定目标LBT BW unit的编号和SFI。
示例的，终端接收到基站发送的DCI之后，根据DCI确定目标LBT BW unit的编号和SFI。随后，基站在一个或多个信道空闲的LBT BW unit上向终端发送下行数据；终端通过激活BWP中的信道空闲的LBT BW unit，接收下行数据。
采用本发明实施例提供的技术方案，通过基站基于LBT信道检测带宽单元来指示SFI，并告知终端哪些LBT BW unit对应的信道空闲，使终端获得明确的SFI与适用的LBT BW unit，实现时隙格式的明确指示，能够提高系统的可靠性。

在一个实施例中，第一发送模块602在目标LBT BW unit所包括的至少一个LBT BW unit上向终端重复发送DCI；其中，DCI中包括信道空闲指示信息和目标服务小区上所有信道空闲的LBT BW unit的SFI，信道空闲指示信息用于表征目标服务小区上所有LBT BW unit各自对应的信道是否空闲。
