具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
为了支持超高可靠性和超低时延传输，需要以较短传输时间传输低时延高可靠业务，同时在其他具有较长传输时间的业务尚未传输或正在传输的过程中，可以抢占部分资源传输。由于上行传输的不同用户间并不清楚被抢占传输，为了尽可能降低对具有高可靠低时延业务的性能影响，需要将抢占资源相关的指示信息通知给被抢占传输的用户，此时具有较长传输时间间隔的业务或具有较低可靠性业务的上行传输将取消传输或停止传输，进而避免与低时延高可靠业务在相同的资源上同时传输导致性能降低。目前，对于下行业务抢占传输是在配置的参考下行资源中以{M，N}＝{14，1}或{7，2}划分出14个分块并且通过 位图(bitmap)通知每个分块是否被抢占，其中M表示时域划分的分块数，N表示频域划分出的分块数。而对于上行业务的抢占传输，并没有有效的指示方式。
上行传输包含两种类型：授权(Grant Based)上行传输与免授权上行传输，其中，Grant Based上行传输指用户根据服务节点的上行授权进行的上行业务传输，其传输资源是确定的；而Grant Free上行传输指用户在半静态配置的一组Grant Free资源上自主选择进行的上行业务传输。对于这一类传输，服务节点无法预先确定具体传输发生在哪个候选资源上。因此，当Grant Free上行传输与其他低优先级的传输资源出现交叠时，基站无法提前通知被抢占用户，这种基于抢占指示的共存解决方式不再适用。本实施例将功率控制作为一种可行的方案，基本思路是当其他低优先级的传输资源与Grant Free上行传输资源交叠的情况下，动态控制Grant Free上行传输的发射功率，提供了实现功率控制的流程和信令格式，从而提高Grant Free传输的性能。
图1为一实施例提供的一种上行传输方法的流程图。如图1所示，本实施例提供的上行传输方法应用于用户终端，包括S110和S120。
在S110中，接收下行控制信息，所述下行控制信息包括资源指示域。
本实施例中，下行控制信息由服务节点发送至用户终端，设置为指示动态授权(Dynamic grant)业务的传输资源，作为确定配置授权(Configured Grant，CG)业务上行传输机制的依据。用户终端根据下行控制信息所指示的指示资源与CG资源的交叠情况，选择上行业务的传输资源，当所选择的传输资源与所述指示资源存在交叠时，进行基于速率匹配或功率控制的上行传输。其中，所述下行控制信息中指示的指示资源与动态授权业务的传输资源也可以不完全等同，例如，由于资源指示开销的原因，所述下行控制信息对指示资源的指示粒度大于上行授权中对动态授权业务传输资源的指示粒度；或者，资源指示方式的不同造成指示的资源不完全相同。服务节点为基站。
在S120中，根据所述资源指示域所指示的指示资源确定上行传输机制。
在一实施例中，下行控制信息包括至少一个资源指示域，每个资源指示域用于指示一组指示资源，不同组指示资源对应不同的功率控制参数。指示资源与功率控制参数之间的映射关系可以由协议预定义，也可以通过广播消息、用 户专用无线资源控制(User Equipment Specific Radio Resource Control)信令等配置。示例性的，每个资源指示域用于指示一组指示资源，每个资源指示域对应于一个资源组，资源组的编号与资源指示域对应。例如，第N个资源指示域对应于资源组N，即在第N个资源指示域内指示的被占用的传输资源属于资源组N，资源组N对应于一套功率控制参数。
在一实施例中，确定上行传输机制包含以下至少之一：在与指示资源交叠的CG资源有至少两个的情况下，从至少两个CG资源中确定用于传输上行数据的目标资源；提升在目标资源上传输上行数据的发射功率；在所述目标资源内进行基于所述指示资源的速率匹配的上行数据传输。

图2为一实施例提供的指示资源与配置授权资源交叠的示意图。如图2所示，在预定义的参考上行资源(Reference Uplink Resource，RUR)内，DCI中的指示资源(实线框内的斜线区域)与CG资源(虚线框内的区域)交叠。用户终端根据DCI的指示资源确定上行传输机制，上行传输机制包括速率匹配和功率控制两种方式，其中，速率匹配是指利用CG资源与指示资源的非交叠部分传输上行数据，而对于交叠部分不映射上行数据，从而减少传输资源、提高上行传输的码率；功率控制是根据DCI中的指示资源对应的控制功率参数，提高在CG资源上传输所述上行业务的发射功率，从而实现对优先级较高的业务的可靠传输。
在一实施例中，所述根据所述资源指示域所指示的指示资源确定上行传输机制，包括：根据调制编码机制(Modulation and Coding Scheme，MCS)等级与第一门限值的关系，基于所述指示资源确定配置授权资源的上行传输机制。本实施例中，用户终端根据配置的MCS等级确定采用的上行传输机制，即采用 速率匹配的上行传输机制还是采用功率控制的上行传输机制。
在一实施例中，在MCS等级大于或等于第一门限值的情况下，在CG资源内进行对指示资源速率匹配的上行数据传输，交叠区域不映射上行数据；在MCS等级小于第一门限值的情况下，根据与CG资源存在交叠的指示资源对应的功率控制参数，提升在CG资源上的上行传输的发射功率。
本实施例中，第一门限值是可以由协议预定义，也可以由服务节点通知给用户终端。示例性的，第一门限值为MCS 8，如果用户终端在CG资源内进行上行传输所配置的MCS等级为MCS 6，小于第一门限值，则根据该指示资源对应的功率控制参数提升该CG资源的上行传输的发射功率；如果用户终端在CG资源内进行上行传输所配置的MCS等级为MCS 10，则对该CG资源进行速率匹配的上行数据传输，即，在指示资源与CG资源的非交叠区域传输上行数据，这种情况下，交叠区域不能映射上行数据，传输资源减少，从而提高上行传输的码率。本实施例中，在MCS等级等于第一门限值的情况下，采用速率匹配的上行传输机制。
在一实施例中，在MCS等级大于第一门限值的情况下，在CG资源内进行对指示资源速率匹配的上行数据传输，交叠区域不映射上行数据；在MCS等级小于或等于第一门限值的情况下，根据与CG资源存在交叠的指示资源对应的功率控制参数，提升在CG资源上的上行传输的发射功率。本实施例中，在MCS等级等于第一门限值的情况下，采用功率控制的上行传输机制。

本实施例中，在CG资源与指示资源交叠的情况下，首先计算在采用速率匹配的上行传输机制的情况下所需采用的第一码率，在第一码率大于或等于第二 门限值的情况下，根据与配置授权资源存在交叠的指示资源对应的功率控制参数提升在CG资源上的上行传输的发射功率，避免由于采用速率匹配的上行传输机制的码率过高而导致的传输可靠性不满足需求的问题；在第一码率小于第二门限值的情况下，进行速率匹配的上行数据传输，交叠区域不映射上行数据，以减少传输资源、提高码率。本实施例中，第一码率等于第二门限值的情况下，采用功率控制的上行传输机制。
在一实施例中，在第一码率大于第二门限值的情况下，根据与CG资源存在交叠的指示资源对应的功率控制参数，提升在该CG资源上的上行传输的发射功率；在第一码率小于或等于第二门限值的情况下，在该CG资源内进行对指示资源速率匹配的上行数据传输，交叠区域不映射上行数据。本实施例中，第一码率等于第二门限值的情况下，采用速率匹配的上行传输机制。

在一实施例中，根据资源指示域所指示的指示资源确定上行传输机制，包括：在配置授权资源与至少两组指示资源存在交叠的情况下，根据至少两组指示资源对应的功率控制参数中的最大功率调整量提升在配置授权资源上的上行传输的发射功率。本实施例中，用户终端确定的上行传输机制为基于功率控制的机制，指示资源有两组，分别对应于不同的功率控制参数。
在一实施例中，用户终端根据至少两组指示资源对应的功率控制参数中的最大功率调整量提升在CG权资源上的上行传输的发射功率，例如，第一组指示资源对应的功率控制参数中的功率调整量为P1，第二组指示资源对应的功率控制参数中的功率调整量为P2，P2大于P1，则根据第二组指示资源对应的功率控制参数提升在CG资源上的上行传输的发射功率，将在CG资源上的上行传输的发射功率提升P2。
在一实施例中，所述根据所述资源指示域所指示的指示资源确定配置授权资源的上行传输机制，包括：在CG资源与至少一组指示资源交叠的情况下，且在所述CG资源为至少两个的情况下，根据所述指示资源在所述CG资源中确定目标资源；确定在所述目标资源上的上行传输机制。

本实施例中，第三门限值是协议预定义的，或者由服务节点通知给用户终端的。如果用户终端在目标资源内进行上行传输所配置的MCS等级小于第三门限值，则根据该指示资源对应的功率控制参数提升该目标资源的上行传输的发射功率；如果用户终端在目标资源内进行上行传输所配置的MCS等级大于或等于第三门限值，则在目标资源内对所述指示资源进行速率匹配的上行传输，即，在指示资源与目标资源的非交叠区域传输上行数据，这种情况下，交叠区域不映射上行数据，传输资源减少，从而提高上行传输的码率。本实施例中，在MCS等级等于第三门限值的情况下，采用速率匹配的上行传输机制。

本实施例中，用户终端确定的上行传输机制为基于功率控制的机制，指示资源有两组，分别对应于不同的功率控制参数。
在一实施例中，用户终端根据至少两组指示资源对应的功率控制参数中的最大功率调整量提升在配置授权资源上的上行传输的发射功率，例如，调整到第一组指示资源对应的功率控制参数，所需的功率调整量为P3，调整到第二组指示资源对应的功率控制参数，所需的功率调整量为P4，P4大于P3，则根据P4提升目标资源的发射功率，将目标资源的发射功率提升P4。

资源指示域1 资源组1
资源指示域2 资源组2
资源指示域3 资源组3
资源指示域4 资源组4
表1为资源指示域与资源组编号的映射关系表。如表1所示，每个资源指示域对应于一个资源组。
本实施例中资源指示域的数量与资源组的数量相关。例如，系统预定义了4个资源组，或者，基站通过高层信令为用户终端配置了4个资源组，则DCI中的资源指示域的数量也定义为4，DCI内信息比特的开销确定为每个资源指示域的比特数乘以4。
图9为一实施例提供的待指示的时频域资源的示意图。如图9所示，虚线方框的区域为DCI所指示的目标时频资源范围，也可以称为参考上行资源(Reference Uplink Resource，RUR)，其中，黑色方框所示的区域(图9中有两个黑色方框区域)为资源组1内的资源，斜线方框所示的区域为资源组2内的资源，点状方框所示的区域为资源组4内的资源，上述资源为RUR内待指示的时频域资源。
在一实施例中，在每个资源指示域内指示对应的资源组内包含的时频域资源，例如，利用时域资源分配与频域资源分配联合指示资源组内的一个或多个资源。以图9中的待指示资源为例，DCI中的资源指示域1、资源指示域2、资源指示域4分别用于指示资源组1内的资源、资源组2内的资源、资源组4内的资源。在图9中的RUR内，不存在属于资源组3内的资源，示例性的，资源指示域3的所有比特可以置为预先定义的取值，例如全置为0，表示RUR内不存在资源组3内的资源。
在一实施例中，所述资源指示域用于基于位图指示对应的资源组内所包含的指示资源。本实施例中，预先对RUR内的资源编号，在每个资源指示域内指示对应的资源组内所包含的资源编号。
图10为一实施例提供的待指示资源编号的示意图。如图10所示，RUR内包含8个待指示资源，基于位图指示对应的资源组内所包含的指示资源。
例如，资源指示域1的位图为10010000，每一比特代表对应资源是否属于资源组1，其中，1代表属于，0代表不属于，则本实例中的资源1和资源4属于资源组1；资源指示域2的位图为00001000，说明资源5属于资源组2；资源指示域3的位图为01100001，说明资源2、资源3、资源8属于资源组3；资源指示域4的位图为00000000，说明当前RUR内没有资源属于资源组4。本实施例中，RUR区域内不属于任何资源组的资源，可以理解为不需要进行功率控制的上行传输资源。
在一实施例中，所述资源组与功率控制参数之间具有映射关系，其中，所述功率控制参数包括以下至少之一：开环功控参数和闭环功控参数。
本实施例中，每个资源组对应一套功率控制参数，在用户终端的CG资源与服务节点所指示的资源组中的资源交叠的情况下，用户终端根据该资源组对应 的功率控制参数确定上行传输机制。功率控制参数包括以下至少之一：开环功控参数(如目标接收功率P0、路损补偿系数α等)和闭环功控参数(如闭环功率调整量等)。
表2为资源组与功率控制参数的映射关系表。如表2所示，每个资源组对应于一套功率控制参数，功率控制参数以开环工控参数为例。本实施例中，资源组通过资源组编号区分，资源组与功率控制参数的映射关系即为资源组编号与功率控制参数的映射关系。在下行控制信息中指示了每个资源组内包含的具体资源。
表2资源组与功率控制参数的映射关系表
资源组编号 功率控制参数
资源组1 P0＝-106dBm，α＝1
资源组2 P0＝-100dBm，α＝1
资源组3 P0＝-94dBm，α＝1
资源组4 P0＝-88dBm，α＝1
在一实施例中，资源组与功率控制参数的映射关系通过协议预定义，例如，通过协议预定义如表2所示的映射关系，这种情况下，每个资源组编号所对应的功率控制参数的取值是固定的，且对于所有的用户终端，上述映射关系是相同的。
在一实施例中，资源组与功率控制参数的映射关系通过广播消息配置。这种情况下，对于所有的用户终端，上述映射关系也是相同的，但功率控制参数的取值可以配置，例如，与资源组1对应的功率控制参数P0可以配置为-106dBm以外的其他数值。
在一实施例中，资源组与功率控制参数的映射关系通过用户专用无线资源控制信令(User Equipment Specific Radio Resource Control)或用户组专用无线资源控制(User Equipment Group Specific Radio Resource Control)信令配置。本实施例中，无线资源控制(Radio Resource Control，RRC)信令可以是面向一个用户终端(User Equipment，UE)的，不同的UE，资源组编号与功率控制参数之间的映射关系可以不同；RRC信令也可以是面向一组UE的，属于不同组的 UE，资源组编号与功率控制参数之间的映射关系可以不同。
表3为资源组与功率控制参数的另一映射关系表。以RRC信令面向UE为例，对于UE1，配置了如表2所示的映射关系表，对于UE2，配置了如表3所示的映射关系表，两个UE所配置的映射关系不同。

资源组1 P0＝-100dBm，α＝1
资源组2 P0＝-97dBm，α＝1
资源组3 P0＝-94dBm，α＝1
资源组4 P0＝-91dBm，α＝1
在一实施例中，在采用用户组专用无线资源控制信令配置映射关系的情况下，依据一定的特性将UE分组，例如，根据UE上行传输所配置的MCS对UE分组，在同一MCS等级区间的UE可以定义在同一个用户组内。其中，MCS等级区间可以是协议预定义的。例如，MCS 0-3为同一个MCS等级区间，MCS 4～8为一个MCS等级区间，MCS 9～12为一个MCS等级区间，MCS13及以上定义为一个MCS等级区间。
在一实施例中资源组与功率控制参数的映射关系由RRC信令和介质访问控制(Media Access Control，MAC)层信令联合配置，其中，RRC信令设置为配置功率控制参数池，MAC层信令设置为配置所述功率控制参数与所述资源组的映射关系，所述功率控制参数为在所述功率控制参数池中选定的子集。
表4资源组与功率控制参数的另一映射关系表
资源组编号 功率控制参数
资源组1 功率控制参数2
资源组2 功率控制参数5
资源组3 功率控制参数9
资源组4 功率控制参数13
表4为资源组与功率控制参数的另一映射关系表。本实施例中，通过RRC 信令配置一个功率控制参数池，通过MAC层信令在功率控制参数池内选择一个子集作为可配置的功率控制参数，并与资源组建立映射关系。例如，功率控制参数池包含16组功率控制参数，分别编号为功率控制参数1～16；MAC层信令在这16组功率控制参数中选择可配置的功率控制参数，例如，通过16bit的bitmap选择4组功率控制参数：0100 1000 1000 1000，即功率控制参数2、5、9、13，则资源组与功率控制参数的映射关系如表4所示。
上述实施例通过定义资源组与功率控制参数之间的映射关系，并通过下行控制信息向用户终端指示资源，有效地支持了通过功率控制或速率匹配的方式实现用户终端间上行传输资源的复用，从而有效保证了高优先级的业务上行传输业务的传输效率，提高了通信效率和可靠性。
