附图说明
为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示意性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干个接入网设备120。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。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，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G新空口(New Radio，NR)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。为方便本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
终端13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他处理设备，以及各种形式的终端(User Equipment，UE)，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
在本公开实施例中，终端13包括：车辆131、其它车辆132、基础设施133和行人134。
车辆对车辆(Vehicle to Vehicle，V2V)是指车辆131与其它车辆132之间的通信，本方车辆将本方的相关信息发送给对方车辆，相关信息包括行驶速度、地理位置、行驶方向和行驶状态等。
车辆对基础设施(Vehicle to Infrastructure，V2I)是指车辆131与基础设施133之间的通信，基础设施133包括车辆行驶过程中遇到的所有基础设施，包括红绿灯、公交站、大楼和隧道等建筑设施。
车辆对行人(Vehicle to Pedestrian，V2P)是指车辆131与行人134之间的通信。行人(Pedestrian)泛指行人携带的具有移动通信能力的电子设备，比如，手机和可穿戴设备，其中，可穿戴设备包括智能手环、智能手表和智能戒指等。
在本公开实施例中，将车辆131称为第一终端，将其它车辆132、基础设施133和行人134称为第二终端来举例说明，但是两者也可以互换角色，对此不加以限定。
可选地，上述第一终端和第二终端为支持直连通信的终端，上述通信系统可以是NR系统及后续演进系统。
在NR系统中，由于NR系统的工作频率较高，如：FR2频率范围的28GHz或39GHz，然而，伴随着工作频率较高，无线信道不可避免的受到更高的路径损耗，从而对小区的覆盖质量和服务质量产生了较大的挑战。
在对不同信道的覆盖情况进行评估的过程中，通常在发送端发送数据的同 时，在其中穿插导频序列，从而接收端根据接收到的导频序列和已知的发送序列确定信道情况，进而确定系统或者数据部分的信道情况，以及，从而能够得到发送的数据内容。其中，根据导频序列进行信道估计时，将接收到的导频序列与已知的发送序列相除，得到信道估计值H，通过H进行信道评估。
在NR系统中，通过设计解调参考信号(Demodulation Reference Signal，DMRS)辅助系统获得信道估计值，DMRS还用于上行控制信道和上行数据信道的相关解调。可选地，
当前的NR系统中，支持两种DMRS类型，type1 DMRS和type2 DMRS，其中，每种类型的DMRS又包括单符号DMRS(包括1个OFDM符号)或双符号DMRS(包括2个OFDM符号)，其中，通过高层信令配置DMRS类型。可选地，UE根据高层配置参数dmrs-Type来确定DMRS向物理资源的映射。可选地，DMRS序列映射公式映射到资源元素(Resource Element，RE)上。
RE即资源元素，或资源粒子，是LTE物理资源中最小的资源单位；在时域上占用1个OFDM符号(1/14ms)，频域上为1个子载波(15KHz)。平常所说的符号，即调制后的数据符号，是映射到RE上的，与OFDM符号是两个不同的概念。
针对上述两种DMRS类型分别进行说明，其中，type1 DMRS和type2 DMRS的复用方式和配置方式如下所示：
type1 DMRS：示意性的，请参考图2，对于单符号DMRS201，一个OFDM符号内的子载波被分为两组频分的梳妆资源，其中每组梳妆资源构成一个码分复用(Code Division Multiplexing，CDM)组。CDM组内部通过2个正交覆盖码(Orthogonal Cover Code，OCC)支持两端口复用，最多支持4个端口。双符号DMRS202在单符号结构的基础上增加时域OCC，每组梳妆资源占用连续的两个OFDM符号，每个CDM组通过4个时频域的OCC实现四个正交端口，因此最多支持8个正交端口。
type2 DMRS：示意性的，请参考图3，对于单符号DMRS301，一个OFDM符号内的子载波被分为3个CDM组，每个CDM组由两对相邻的两个子载波构成，CDM组内通过2个OCC支持2端口复用，组间支持频分复用(Frequency Division Multiplexing，FDM)，因此最多支持6端口；双符号DMRS302在单符号DMR301结构的基础上增加了时域正交覆盖码(Time Domain-Orthogonal  Cover Code，TD-OCC)，每个CDM组占用连续的两个OFDM端口，3个CDM组中最多支持12个端口。
即两个端口在同一个子载波上两个相邻的符号上采用不同的正交覆盖码，例如端口0对应码字为{1，1}，端口1对应码字为{1，-1}，这样当两个端口同时发送时，由于任何一个端口上在同一个子载波相邻两个符号上信道增益可以认为相同，接收端可以利用对应的正交码字将端口上叠加的信道分开。
对于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)而言，仅支持type1 DMRS的配置。
在现有的NR系统中，下行控制信息(Downlink Control Information，DCI)中包含PUSCH可以用的端口数集合，以及其调度资源上不用于数据传输的CDM组数量。若在向第一UE分配的天线端口所对应的CDM组以外，还存在其他CDM组不用于数据传输，则不用于数据传输的CDM组中的天线端口可能是属于其他被调度的第二UE，则第一UE的数据不映射到这些CDM组占用的RE上。
基于上述情况，处于覆盖边缘的UE，当存在不能映射的资源时，对UE的编码效率和性能存在较大的影响。
针对上述情况，本公开实施例中提供了一种覆盖增强中，上行业务信道资源映射的方法，图4是本公开一个示例性实施例提供的资源映射方法的流程图，以该方法应用于第一终端中为例，如图4所示，该方法包括：
步骤401，接收第一配置信令，第一配置信令中包括第一信息字段，第一信息字段用于指示第一终端扩展业务信道资源映射。
该第一配置信令包括无线资源控制(Radio Resource Control，RRC)信令、媒体访问控制控制单元(Media Access Control Element，MAC CE)或物理层信令中的至少一种。
第一配置信令用于指示第一终端以扩展映射样式扩展业务信道资源映射。
可选地，以本公开实施例中的接入网设备实现为基站为例，第一终端为基站覆盖边缘的终端。首先，基站根据UE的信号质量、发送功率、信道比等参数确定UE是否为基站覆盖边缘的终端。也即，UE向基站上行传输数据时，基站获取UE的信号质量、发送功率、信道比等参数，响应于信号质量低于质量阈值、 发送功率大于功率阈值或信道比在要求信道比范围内，则确定该UE为基站覆盖边缘的终端。
而针对基站覆盖边缘的UE(即本实施例中的第一终端)，当存在终端与该UE频分复用DMRS符号时，存在不能映射的资源，从而影响编码效率，降低通信性能。从而影响了基站的覆盖能力。故本公开实施例中，由基站向处于覆盖边缘的第一终端发送第一配置指令，该第一配置指令中的第一信息字段用于指示第一终端扩展资源映射，可选地，第一信息字段例如通过1个或多个bit来指示第一终端进行资源映射(可选地，以预配置或预定义的扩展映射样式进行资源映射，例如该扩展映射样式是预先约定好的和/或存储在第一终端中)；或，第一信息字段仅指示扩展映射样式，只要终端收到了该扩展映射样式，即相当于指示第一终端以第一信息字段所指示的扩展映射样式扩展业务信道资源映射；或，第一配置信令中包括第二信息字段，第一信息字段用于指示第一终端以第二信息字段所指示的扩展映射方式扩展业务信道资源映射。
也即，本实施例中，基站通知覆盖边缘UE，允许该覆盖边缘UE扩展数据映射，和/或，扩展映射的扩展映射方式(pattern)。
可选地，基站同时通知与该第一终端采用频分复用方式复用DMRS符号的其他终端，在第一终端(边缘UE)采用扩展映射样式进行资源映射的DMRS符号内，初始映射DMRS的RE内不进行映射。
也即，第一终端与第二终端频分复用DMRS符号，第一终端占用DMRS符号内的第一资源元素位置，第二终端占用DMRS符号内的第二资源元素位置，则基站向第二终端发送第二配置信令，该第二配置信令用于指示第二终端取消在第二资源元素位置上进行资源映射。从而，第一终端在进行资源映射时，能够在第一资源元素位置和第二资源元素位置上，通过全部或者部分资源元素位置进行资源映射。
步骤402，根据第一配置信令扩展资源映射。
第一终端根据第一配置信令，以扩展映射样式(pattern)进行扩展资源映射。
可选地，第一终端还用于以扩展映射样式完成数据速率匹配。
也即，第一终端在接收到第一配置指令后，在进行速率匹配操作以及资源映射操作时，按照扩展映射样式进行速率匹配以及资源映射。
可选地，该扩展映射样式为预配置的；或，扩展映射样式为预定义的；或，扩展映射样式为根据第一配置信令确定的。
响应于扩展映射样式为预配置的，即基站预先向UE发送配置信令，该配置信令中包括扩展映射样式的配置信息，当UE接收到第一配置信令时，根据扩展映射样式的配置信息确定扩展映射样式，并以扩展映射样式进行资源映射。
响应于扩展映射样式为预定义的，即通信协议中预先定义了扩展映射样式，从而当UE接收到第一配置信令时，根据扩展映射样式进行资源映射。
响应于扩展映射样式为根据第一配置信令确定的，则包括如下情况中的任意一种：1、第一配置信令中包括第二信息字段，该第二信息字段用于指示扩展映射样式，如：第二信息字段中包括扩展位置的编号信息。2、第一信息字段还用于指示扩展映射样式，示意性的，当第一信息字段取第一取值时，则对应第一扩展映射样式，如：对应第一扩展位置的编号；当第一信息字段取第二取值时，则对应第二扩展映射样式，如：对应第二扩展位置的编号。
可选地，第一终端根据第一配置指令，在指定时隙slot或符号内扩展资源映射。
其中，该指定时隙slot或符号为预配置的，或，该指定时隙slot或符号为预定义的，或，该指定时隙slot或符号为根据第一配置信令确定的。
响应于指定时隙slot或符号为预配置的，即基站向第一终端发送配置信令，该配置信令向第一终端配置有接收到第一配置指令后，扩展映射样式对应的时隙slot或符号的数量，也即，在接收到第一配置信令后，在该数量内的slot或符号即为指定时隙slot或符号；或，基站向第一终端发送配置信令，该配置信令向第一终端配置有接收到第一配置指令后，扩展映射样式对应的时隙slot或符号排布，也即，在接收到第一配置信令后，在该排布方案内的时隙slot或符号即为指定时隙slot或符号。
响应于指定时隙slot或符号为预定义的，即协议中预先定义了在UE接收到第一配置指令后，指定时隙slot或符号的确定方式，UE在接收到第一配置指令后，根据协议预定义的指定时隙或指定符号，进行资源映射的扩展。
响应于指定时隙slot或符号为根据第一配置指令确定的，则该第一配置指令中包括第三信息字段，该第三信息字段用于指示指定时隙slot或符号。UE在接收到第一配置指令中，根据第一信息字段确定需要进行业务信道资源映射的扩展，并根据第三信息字段确定需要扩展业务信道资源映射的时隙范围。
示意性的，第三信息字段用于指示第一终端在后续N个slot上进行业务信道资源映射的扩展，则第一终端在接收到第一配置信令后，在后续N个slot上， 以扩展映射样式进行资源映射，N为正整数。
示意性的，本公开实施例中涉及的DMRS映射类型为type1，位于基站覆盖边缘的第一终端为UE1，与UE1频分复用DMRS符号的第二终端为UE2，也即UE1和UE2频分复用DMRS符号。一个资源数据块(Resource Block，RB)在频域上包括12个子载波，时域上为1个slot(包括14个symbol)，RE映射到频域上的子载波时，UE1占用的参考信号RE编号为0、2、4、6、8、10；UE2占用的参考信号RE编号为1、3、5、7、9、11。
初始时候，UE1仅在自身占用的参考信号RE上映射，也即，仅在0、2、4、6、8、10的RE位置上进行映射，而RE位置1、3、5、7、9、11空着，为RE2所占用，当基站向UE1发送第一配置信令，即指示UE1以扩展映射样式进行资源映射时，UE扩展参考信号RE的映射，且允许其他后续N个slot上占用UE2的参考信号RE进行扩展数据映射。则，UE在计算可以承载的物理资源时，结合UE1和UE2的参考信号RE位置进行考虑，将数据映射到相应的位置上。
基站在向UE1发送第一配置信令时，向UE2发送第二配置信令，该第二配置信令用于指示UE2取消在初始参考信号RE位置上进行资源映射。UE2在接收到第二配置信令后，停止在编号为1、3、5、7、9、11的RE位置上进行资源映射。
值得注意的是，上述实施例中以UE1和UE2两个终端频分复用DMRS符号为例进行说明，在一些实施例中，与UE1频分复用DMRS符号的终端还可以更多，本公开实施例对此不加以限定。
综上所述，本公开实施例提供的资源映射方法，通过第一配置信令向第一终端扩展业务信道的资源映射，从而第一终端能够以扩展映射样式进行资源映射，在无法占用的RE位置上进行数据传输，从而降低码率、提高数据传输的可靠性以及提高了基站的覆盖能力。
在一个可选的实施例中，由接入网设备向第一终端发送第一配置信令，以及向第二终端发送第二配置信令，且第一终端和第二终端为频分复用DMRS符号的两个终端。

可选地，第一终端位于基站覆盖边缘，基站根据UE的信号质量、发送功率、信道比等参数确定UE是否为基站覆盖边缘的终端。
针对基站覆盖边缘的UE(即本实施例中的第一终端)，当存在终端与该UE频分复用DMRS符号时，存在不能映射的资源，从而影响编码效率，降低通信性能。从而影响了基站的覆盖能力。故本公开实施例中，由基站向处于覆盖边缘的第一终端发送第一配置指令，该第一配置指令中的第一信息字段用于指示第一终端以扩展映射样式扩展业务信道资源映射。
本实施例中，以第一终端和第二终端频分复用DMRS符号为例进行说明。其中，第一终端占用符号内的第一资源元素位置，第二终端占用符号内的第二资源元素位置，该符号用于指示DMRS符号。

其中，取消资源映射的RE位置为预配置的，或，取消资源映射的RE位置为预定义的，或，取消资源映射的RE位置为通过第二配置信令确定的。
示意性的，第二终端在第二资源元素位置上进行资源映射，则第二配置信令指示第二终端取消在第二资源元素位置上的资源映射。其中，第二配置信令指示第二终端取消在完整第二资源元素位置上的资源映射；或，第二配置信令指示第二终端取消第二资源元素位置中部分RE位置上的资源映射。
示意性的，第二终端占用的参考信号RE编号为1、3、5、7、9、11，则第二配置信令指示第二终端取消在1、3、5、7、9、11的RE位置上的资源映射；或，第二配置信令指示第二终端取消在1、3、5、7的RE位置上的资源映射。
