技术领域

背景技术
在第五代(5th Generation，5G)移动通信，根据探测参考信号(Sounding Reference Signal，SRS)的功能不同，SRS可用于波束管理(Beam management)、基于码本Codebook的传输、基于非码本non-Codebook的传输和天线切换(Antenna Switching)发送。终端UE可通过高层信令获取多个SRS资源集合，每个SRS资源集合配置中包含其用途、周期特性等配置。
5G移动通信系统中，在1个时隙内，SRS资源可占用最后6个符号，高层信令可配置SRS资源占用1/2/4个符号传输，并支持频域上的梳状comb结构为comb-2和comb-4。根据SRS资源发送周期的不同，支持周期性发送SRS资源、半持续发送SRS资源和非周期触发SRS资源。非周期SRS资源时，高层信令配置每个SRS资源触发状态对应的SRS资源集合和时隙偏移量，该偏移量指示了终端(User Equipment，UE)接收到SRS触发至实际发送之间时隙级的间隔。
由于相关技术中，支持SRS资源频域密度为comb-2和comb-4，使得SRS资源的发送功率较低。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清 楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更可选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的一种SRS资源配置方法、BWP的切换处理方法、网络设备、终端及位置服务器、网络设备、终端和位置服务器可以应用于无线通信系统中。该无线通信系统可以为采用5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
请参见图1，图1是本公开实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。上述网络设备12可以是5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者传输接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
请参见图2，图2是本公开实施例提供的一种SRS资源配置方法的流程图，该方法应用于网络设备，如图2所示，包括以下步骤：
步骤201，向终端发送第一配置信息，所述第一配置信息用于配置探测参考信号SRS资源的图样，所述SRS资源在频域等间隔分布，且间隔的子载波 的数量为M，M为大于4的整数。
本公开实施例中，上述M的大小可以根据实际需要进行设置，例如在一可选实施例中，M可以为6、8或12。具体的，所述频域等间隔分布M个子载波对应的梳状comb结构为comb-M。即当M的取值为6、8或12时，对应的comb结构为com-6、com-8或com-12。
应理解，上述第一配置信息还可以包含除了SRS资源图样信息外，还可以包括SRS资源的带宽信息、SRS资源功率控制信息、SRS资源时域配置信息、SRS资源波束配置信息和SRS资源序列配置信息等与SRS资源发送关联的配置信息。
本公开实施例通过设置SRS资源在频域等间隔分布，且间隔的子载波的数量大于4，相对于相关技术中SRS资源频域密度为comb-2和comb-4，由于增加了SRS资源在频域等间隔，因此，本公开实施例增强了SRS资源的发送功率。
需要说明的是，M的值不同，对应的SRS资源的图样可以不同，例如在可选一实施例中，当M为8时，所述SRS资源的图样由两个连续的资源块(Resource Block，RB)构成。在另一可选实施例中，当M为6或12时，所述SRS资源的图样由一个RB构成。
其中，SRS资源的图样由2个连续的RB构成可以理解为：所述SRS资源在进行时频资源映射时，在1个slot内奇数RB上资源单元(Resource element，RE)位置与SRS资源的图样的奇数RB相同，任意偶数RB上的RE位置与SRS资源图样的偶数RB相同。换句话说，2个连续的RB可以组成一个RB组(RB bundle)，是SRS资源在进行时频资源映射时的最小单元。SRS资源在整个SRS带宽范围内的RE位置以这个RB组为基准不断在频域进行重复获得。
在本公开实施例中，上述第一配置信息还可以用于配置所述SRS资源的梳状结构频域偏移comb offset。进一步的，在一可选实施例中，上述SRS资源的梳状结构频域偏移comb offset，可以由网络设备配置，也可以由协议约定。
当M为8时，所述comb offset用于指示所述SRS资源最后1个符号在 第一RB中最低的RE位置。
当M为6或12时，所述comb offset用于指示所述SRS资源最后1个符号在RB中最低的RE位置。
上述第一RB的位置可以根据实际情况进行设置，具体的，第一RB可以为SRS资源中任意奇数RB或偶数RB。在本公开实施例中，第一RB为奇数还是偶数可以由协议约定、也可以由网络设备进行指示，还可以由终端选择。当由网络设备指示时，可以通过1bit指示当前最低的RE是在奇数RB还是在偶数RB上。
在本公开实施例中，所述comb offset的取值为小于M的自然数。例如，当M为6时，comb offset的取值为小于6的自然数；当M为8时，comb offset的取值为小于8的自然数；当M为12时，comb offset的取值为小于12的自然数。具体的，以M＝8为例进行说明，当comb offset为i时，i为小于8的自然数，表示所述SRS资源的最后一个符号在RB中最低RE的位置为倒数第i+1个RE。当comb offset为0时，对应的所述SRS资源的最后一个符号在RB中最低RE的位置为最后1个RE，具体如图3和图4所示。
进一步的，在本公开实施例中，所述SRS资源占用连续的N个符号；
其中，当M＝6时，N的取值为1、2、4、6或者大于6的整数；
当M＝8时，N的取值为1、2、4、8或者大于8的整数；
当M＝12时，N的取值为1、2、4、6、8、12或者大于12的整数。
具体的，SRS资源占用的连续的N个符号可以为1个时隙slot内的前N个符号、后N个符号，或中间任意位置的N个符号，SRS资源的N个符号不能超过slot边界。
进一步的，上述第一配置信息还可以用于配置所述SRS资源的循环移位(cyclic shift)值。具体的，当comb的结构为comb-6时，该SRS资源的循环移位值可以为小于8的自然数；当comb的结构为comb-8时，该SRS资源的循环移位值可以为小于6的自然数；当comb的结构为comb-12时，该SRS资源的循环移位值可以为小于4的自然数。
进一步的，上述第一配置信息还可以用于配置所述SRS资源的重复因子(repetition factor)值。具体的，当comb的结构为comb-6时，所述重复因子 的取值为1、2、4或6；当comb的结构为comb-8时，所述重复因子的取值为1、2、4或8；当comb的结构为comb-12时，所述重复因子的取值为1、2、4、6或12。
应理解，在本公开实施例中还可以进行RE偏移(RE shift)设置，该RE偏移可以由网络设备指示，也可以由协议约定。例如在一可选实施例中，该RE偏移由网络设备指示时，可以在第一配置信息指示RE偏移。
本公开实施例中，所述RE偏移用于计算所述SRS资源的频域位置，在根据所述RE偏移计算得到所述SRS资源的频域位置超出预设频域范围的情况下，所述SRS资源的频域位置为：按照特定值对所述频域位置取模后的位置。
所述SRS资源的频域位置可以理解为：SRS资源在某个正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号的上RE的位置。
其中，当M＝6或12时，所述预设频域范围为1个RB，所述特定值为12；
当M＝8时，所述预设频域范围为2个RB，所述特定值为24。
具体的，SRS资源的频域位置为：频域位置mod特定值。以comb的结构为comb-8为例进行如下说明：
RE偏移是指SRS资源相邻的符号的RE级的偏移量(频域偏移量)，前1个符号的RE的频域位置可以通过后1个相邻的符号的RE频域位置和配置的RE shift计算获得。当奇数或偶数RB上的某个符号的RE根据RE shift计算要超出连续的2个RB的范围时，可通过取模值(mod 24)使得RE的频域位置落在该连续的2个RB范围内。RE shift可以是正向或负向的偏移。对于comb-8，RE shift的大小可以是1、2或4。例如，当RE shift为1，SRS资源的符号数为8，且comb的结构为comb-8时，对应的SRS资源的图样可以参见图3所示。
进一步的，当RE shift没有被配置时，终端应假设SRS资源所有符号的RE在频域中的位置相同。例如，当SRS资源的符号数为4，且comb的结构为comb-8时，对应的SRS资源的图样可以参见图4所示。
应当说明的是，上述SRS资源的作用可以根据实际需要进行设置，例如， 在本实施例中，上述SRS资源可以用于定位。
在一可选实施例中，当SRS资源占用的符号的数量N大于所述M时，所述SRS资源的最后第M+Y符号的频域位置与最后第Y个符号的频域位置相同，M+Y小于或等于N，且Y为正整数。
进一步的，所述SRS资源的最后第M+Y符号的频域位置的值与最后第Y个符号的频域位置的值相同。
本公开实施例中，SRS资源的可以是最后X个符号的SRS的重复。当SRS资源用作定位时，不论SRS资源的comb结构被配置为多少，SRS资源的符号数N可以大于SRS的comb size X。当SRS资源符号数量N大于SRS的comb size X时，该SRS资源的最后第X+Y≤N符号的频域位置(RE位置)可以与最后第Y个符号的频域位置(RE位置)相同。SRS资源的最后第X+Y符号的频域位置(RE位置)的值可以与最后第Y个符号的频域位置(RE位置)的值也相同。具体的，可以参照图5至10所示的SRS资源图样：
在图5中，comb结构为comb-4，SRS资源占用的符号数为8；
在图6中，comb结构为comb-4，SRS资源占用的符号数为12；
在图7中，comb结构为comb-2，SRS资源占用的符号数为6；
在图8中，comb结构为comb-2，SRS资源占用的符号数为4；
在图9中，comb结构为comb-8，SRS资源占用的符号数为12；
在图10中，comb结构为comb-8，SRS资源占用的符号数为14。
进一步的，基于上述实施例，本公开实施例中，所述方法还可以包括：
向终端发送第一指示信息，所述第一指示信息用于指示所述SRS资源的带宽信息。
本公开实施例中，上述第一指示信息可以携带在上述第一配置信息中进行发送，也可以携带在另一条配置信息进行发送。当通过另一条配置信息进行发送时，该第一指示信息可以在第一配置信息发送前或者发送后进行发送，在此不做进一步的限定。
其中，上述SRS资源的带宽信息可以包含宽带SRS(wideband SRS)或窄带SRS(narrowband SRS)的带宽相关信息。
需要说明的是，可以针对部分场景可以定义终端的部分特定行为。例如， 在所述第一配置信息满足第一预设条件时，所述第一配置信息还用于指示所述终端对执行预设操作；其中，所述第一预设条件包括以下任一项：
所述M＝6，所述SRS资源的带宽信息为8RB、16RB或32RB；
所述M＝12，所述SRS资源的带宽信息为4RB、8RB、16RB、20RB、28RB或32RB。
其中，上述预设操作可以包括：不发送所述SRS资源；
或者对所述SRS资源的生成序列进行截取(truncate)后发送。
应理解，终端的上述部分特定行为还可以由通过协议约定或者终端选择。以下针对comb结构的不同情况进行详细说明：
情况1：若网络设备配置SRS资源的comb结构为comb-12时，且宽带SRS或窄带SRS的带宽被配置为4RB、8RB、16RB、20RB、28RB或32RB时，终端不发送SRS资源。相应的，网络设备不接收SRS资源。或者，若网络设备配置SRS资源的comb结构为comb-12时，且宽带SRS或窄带SRS的带宽被配置为4RB、8RB、16RB、20RB、28RB或32RB时，终端要对SRS资源的生成序列(低峰均功率比序列(low peak to average power ratio sequence，Low-PAPR sequence)或ZC序列)进行截取(truncate)后发送。该截取可以理解为终端从一个特定长度的序列(Low-PAPR sequence或ZC序列)中取一段，或者终端取该特定长度的序列的一个子集(subset)。
相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
情况2：若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE不发送SRS。相应的，网络设备不接收SRS。或者，若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE要对SRS的生成序列(Low-PAPR sequence或ZC序列)进行截取后发送。相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
应理解在其他实施例中，若网络设备配置SRS资源的comb结构为comb-3时，且宽带SRS或窄带SRS的带宽被配置为16RB或32RB时，UE不发送 SRS。相应的，网络设备不接收SRS。或者，若网络设备配置SRS资源的comb结构为comb-3时，且宽带SRS或窄带SRS的带宽被配置为16RB或32RB时，UE要对SRS的生成序列(Low-PAPR sequence或ZC序列)进行截取后发送。相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
进一步的，在进行SRS资源带宽相关的配置时，可以采用以下任一种方法进行配置。
在实施方式1中：网络设备可以向所述终端发送第二配置信息，所述第二配置信息用于配置所述终端在上行激活带宽部分UL active BWP内发送所述SRS资源。此时，终端可以根据第二配置信息，可以在UL active BWP内发送SRS资源。
在实施方式2中：网络设备可以向所述终端发送第三配置信息，所述第三配置信息为所述第一BWP的配置信息，所述第三配置信息用于配置所述终端在所述第一BWP上发送所述SRS资源，所述第一BWP为专用于定位的上行带宽部分UL BWP。此时，终端可以根据第三配置信息在第一BWP上发送SRS资源。
在实施方式3中，上述第一配置信息与所述终端的上行带宽部分UL BWP配置无关。也就是说，UL BWP配置信息可以不包含SRS资源的配置信息。SRS资源配置信息也可以不包含UL BWP的配置信息。SRS资源可以基于小区配置。
本实施方式3中，由于第一配置信息与UL BWP配置无关，从而在SRS资源用于定位时不会由于BWP限制SRS资源的发送，避免由于SRS发送的带宽限制定位的精度。
具体的，针对上述实施方式3，所述第一配置信息与所述终端的上行带宽部分UL BWP配置无关的行为可以由协议约定、网络设备配置或者终端选择。当采用网络设备配置时，上述方法还可以包括：
向所述终端发送第二指示信息，所述第二指示信息用于指示所述第一配置信息与所述UL BWP配置无关。
上述第二指示信息可以携带在上述第一配置信息中进行发送，也可以携 带在另一条配置信息进行发送。当通过另一条配置信息进行发送时，该第二指示信息可以在第一配置信息发送前或者发送后进行发送，在此不做进一步的限定。
应理解，所述第一配置信息与所述UL BWP配置无关包括：所述SRS资源的带宽信息和基带参数numerology与所述UL BWP配置无关。
进一步地，SRS资源的最大带宽与UE能力有关。具体的，在本实施例中，上述方法还可以包括：
接收所述终端发送的能力信息，所述能力信息包括UE可支持的最大上行发送带宽；
根据所述最大上行发送带宽确定所述SRS资源的频域范围。
本公开实施例中，在确定SRS资源的频域范围后，可以将SRS资源的频域范围发送给终端，具体的，所述SRS资源的频域范围可以在上述第一配置信息中发送，也可以通过其他配置信息进行发送。
进一步的，UL BWP的切换与所述终端发送所述SRS资源无关。也就是说，当SRS资源与UL BWP无关时，UL BWP切换的行为不会影响终端发送SRS资源。
或者，即使SRS资源的配置与UL BWP配置无关，UL BWP切换时，终端也可以停止发送SRS。
进一步的，所述SRS资源的频域范围可以位于所述UL BWP配置内，也可以位于所述UL BWP配置外。应理解，终端可以被配置最多4个UL BWP，SRS资源的频域范围在UL BWP配置内是指SRS资源的频域范围不超过终端被配置的多个UL BWP一起占用的频域范围。
应当说明的是，用于定位的上行资源可不限于SRS，还可以是其他上行定位参考信号或上行定位资源，本公开实施例中，SRS资源的发送与UL BWP配置无关，在其他实施例中，终端的行为还可以为用于定位的上行定位参考信号或上行定位资源与UL BWP配置无关。
例如，终端的行为可以包括：
接收网络设备发送的目标配置信息，所述目标配置信息用于配置第一对象，所述第一对象包括用于定位的上行定位参考信号或上行定位资源，目标 配置信息与UL BWP配置无关。
进一步的，所述第一配置信息与所述UL BWP配置无关包括：所述SRS资源的带宽信息和基带参数numerology与所述UL BWP配置无关。
进一步的，目标配置信息与UL BWP配置无关可以是协议约定、网络设备配置或终端选择。
进一步的，所述第一对象的频域范围位于所述UL BWP配置内，或者所述第一对象的频域范围位于所述UL BWP配置外。
相关技术中，上行定位时，需要多个目标对象接收UE发送的SRS资源。当UE切换BWP时，依靠相关技术，邻小区完全不会获得BWP切换的信息，从而无法正确接收BWP切换后的SRS资源。上述目标对象为TRP、小区cell或基站(Base Station，BS)。参照图11，为了保证参与定位的邻小区可以获得BWP的切换信息，在本公开实施例中，还提供了一种带宽部分BWP的切换处理方法，应用于第一网络设备，所述第一网络设备为终端当服务的网络设备，所述方法包括：
步骤1101，在终端进行BWP切换时，将切换后的第一BWP的相关信息发送至第二网络设备，所述第二网络设备包括参与所述终端定位的网络设备中除所述第一网络设备之外的其他网络设备；所述第一BWP用于所述终端发送第一对象，所述第一对象包括上行定位参考信号或上行定位资源。
在本公开实施例中，上述终端进行BWP切换具体指终端进行UL BWP切换，上述第一网络设备可以是当前为终端提供服务的基站(gNodeB，gNB)或者cell，即serving gNB或者serving cell。在一可选实施例中，上述第一对象为探测参考信号SRS资源，该SRS资源comb结构设计具体可以采用相关技术中的comb-2或comb-4的设计，也可以采用本公开实施例提供的comb-6、comb-8或comb-12的设计，具体的，comb-6、comb-8或comb-12的设计可以参照上述实施例，在此不再赘述。
应理解，在向第二网络设备发送第一BWP的相关信息时，在一可选实施例中，可以直接向第二网络设备发送第一BWP的相关信息。具体的，所述将切换后的第一BWP的相关信息发送至第二目标网络设备包括：
通过Xn接口直接向所述第二网络设备发送所述第一BWP的相关信息；
在一可选实施例中，可以间接向第二网络设备发送第一BWP的相关信息。具体的，所述将切换后的第一BWP的相关信息发送至第二目标网络设备包括：
向位置服务器发送所述第一BWP的相关信息，以供位置服务器向所述第二网络设备转发所述第一BWP的相关信息。
本公开实施例通过在终端进行UL BWP切换时，由第一网络设备将切换后的第一BWP的相关信息发送至第二网络设备。这样可以保证每一用于定位的第二网络设备可以获得终端切换后的第一BWP的相关信息。因此本公开实施例，可以保证参与定位的各网络设备可以正确的接收终端在切换后的第一BWP上发送的第一对象，从而提高了定位的可靠性。
进一步的，上述第一BWP的相关信息包括所述第一BWP的时域配置信息，以及所述第一BWP配置或所述第一BWP的标识信息。
进一步的，所述第一BWP配置信息中可以包含第一对象的配置信息。
进一步的，上行定位时，第一网络设备可以将与终端关联的全部UL BWP配置信息发送给位置服务器，以供位置服务器向所述第二网络设备转发全部UL BWP配置信息。所述位置服务器，可以将与终端关联的全部UL BWP配置信息发送给第二网络设备。在终端进行UL BWP切换时，上述第一BWP相关信息可以只包含第一BWP时域配置信息及第一BWP的标识信息即可。第二网络设备，仅需获得第一BWP的标识信息，即可从储存的与终端关联的全部UL BWP配置中选出第一BWP的配置信息，用于接收BWP切换后的第一BWP上发送的第一对象。
在一可选实施例中，所述将切换后的第一BWP的相关信息发送至第二网络设备之前，所述方法还包括：
向所述终端发送第二配置信息，所述第二配置信息用于配置所述终端在上行激活带宽部分UL active BWP内发送所述第一对象。
本实施例中，可以由网络设备指示终端进行BWP的切换。此时，上述第一BWP可以为网络设备重新指示激活的UL BWP。在终端从当前UL active BWP切换到第一BWP后，终端将会在第一BWP上发送第一对象。
在另一可选实施例中，所述将切换后的第一BWP的相关信息发送至目 标网络设备之前，所述方法还包括：
向所述终端发送第三配置信息，所述第三配置信息为所述第一BWP的配置信息，所述第三配置信息用于配置所述终端在所述第一BWP上发送所述第一对象，所述第一BWP为专用于定位的上行带宽部分UL BWP。
在本公开实施例中，所述第一BWP的配置信息包括所述第一BWP的标识信息、所述第一BWP的基带参数numerology信息、所述第一BWP的带宽信息、第一BWP的频域位置信息和所述第一对象的配置信息中的至少一项。
进一步的，在不满足第二预设条件的情况下，向所述终端发送第三指示信息，所述第三指示信息用于指示所述终端进行BWP切换；
其中，所述第二预设条件包括：所述第一BWP包含于所述终端当前激活的BWP，且所述第一BWP的基带参数与所述终端当前激活的BWP的基带参数相同。
本公开实施例中，上述第三指示信息可以携带在上述第三配置信息中进行发送，也可以携带在另一条配置信息进行发送。当通过另一条配置信息进行发送时，该第三指示信息可以在第三配置信息发送前或者发送后进行发送，在此不做进一步的限定。
需要说明的是，在一可选实施例中，上述第一对象为探测参考信号SRS资源，该SRS资源comb结构设计具体可以采用相关技术中的comb-2或comb-4的设计，也可以采用本公开实施例提供的comb-6、comb-8或comb-12的设计，具体的，comb-6、comb-8或comb-12的设计可以参照上述实施例，在此不再赘述。
参照图12，本公开实施例还提供了一种SRS资源配置方法，应用于终端侧，包括：
步骤1201，接收网络设备发送的第一配置信息；其中，所述第一配置信息用于配置探测参考信号SRS资源的图样，所述SRS资源在频域等间隔分布，且间隔的子载波的数量为M，M为大于4的整数。

为例更好的理解本公开的具体实现过程，以下对本公开的具体实现方案进行详细说明：
实现方案1：
当SRS资源被配置用于定位时，网络设备可配置SRS资源的comb结构为comb-8，表示SRS资源在频域等间隔分布，间隔为8个子载波。Comb-8结构可以等效为密度3/2RE/PRB，即2个RB中等间隔分布着3个RE。当SRS资源被配置为comb-8结构时，UE应假设SRS资源的图样由连续2个RB的SRS资源构成，该UE行为可以是网络指示，协议固定。
上述SRS资源的comb offset可以为小于8的整数，表示SRS资源最后1个符号在奇数RB或偶数RB中最低的RE位置。或者，SRS资源的comb offset表示最后一个符号在某RB中最低RE的位置，网络设备另外用1bit指示当前最低的RE是在奇数RB还是在偶数RB上。
上述SRS资源占用的连续N个符号可以是1个slot内最后的N个符号，最开始的N个符号，或者是slot内任意的连续的N个符号。N可以等于8、4、2、1或者N>8的整数。
当SRS资源为comb-8结构时，网络设备还可以配置SRS资源的循环移位值和和重复因子，循环移位值为小于6的整数，重复因子的取值为1、2、4或8。
当SRS资源为comb-8结构时，网络设备还可以配置SRS资源相邻符号的RE偏移。RE偏移是指SRS资源相邻的符号的RE级的偏移量(频域偏移量)，前1个符号的RE的频域位置可以通过后1个相邻的符号的RE频域位置和配置的RE shift计算获得。当奇数或偶数RB上的某个符号的RE根据RE shift计算要超出连续的2个RB的范围时，可通过取模值(mod 24)使得RE的频域位置落在该连续的2个RB范围内。RE偏移可以是正向或负向的偏移。进一步地，对于comb-8，RE shift的大小可以是1、2或4。当RE shift没有被配置时，UE应假设该SRS资源所有符号的RE在频域中的位置相同。
进一步地，当SRS资源不用作定位时，也可以使用上述描述的中的comb-8结构的SRS资源作为其他功能。
进一步地，当SRS资源用作定位时，不论SRS comb结构被配置为多少，SRS资源的占用的连续1个或多个符号可以是1个slot内最后的1个或多个符号，最开始的1个或多个符号，或者是1个slot内中间任意的连续的1个或多个符号。
本公开实施例中，SRS资源的可以是最后X个符号的SRS的重复。当SRS资源用作定位时，不论SRS资源的comb结构被配置为多少，SRS资源的符号数N可以大于SRS的comb size X。当SRS资源符号数量N大于SRS的comb size X时，该SRS资源的最后第X+Y≤N符号的频域位置(RE位置)可以与最后第Y个符号的频域位置(RE位置)相同。SRS资源的最后第X+Y符号的频域位置(RE位置)的值可以与最后第Y个符号的频域位置(RE位置)的值也相同。具体的，可以参照图5至10所示的SRS资源图样.
进一步地，不论SRS资源有没有用作定位，若网络设备配置SRS资源的comb结构为comb-12时，且宽带SRS或窄带SRS的带宽被配置为4RB、8RB、16RB、20RB、28RB或32RB时，终端不发送SRS资源。相应的，网络设备不接收SRS资源。或者，若网络设备配置SRS资源的comb结构为comb-12时，且宽带SRS或窄带SRS的带宽被配置为4RB、8RB、16RB、 20RB、28RB或32RB时，终端要对SRS资源的生成序列(Low-PAPR sequence或ZC序列)进行截取后发送。相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE不发送SRS。相应的，网络设备不接收SRS。或者，若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE要对SRS的生成序列(Low-PAPR sequence或ZC序列)进行截取后发送。相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE不发送SRS。相应的，网络设备不接收SRS。或者，若网络设备配置SRS资源的comb结构为comb-6时，且宽带SRS或窄带SRS的带宽被配置为8RB、16RB或32RB时，UE要对SRS的生成序列(Low-PAPR sequence或ZC序列)进行截取后发送。相应的，网络设备对SRS资源进行接收。该终端行为可以是网络设备指示，协议规定或终端选择。
方案二，在进行上行定位是，与SRS资源带宽相关的配置方法包括以下三种方法：
方法1：SRS资源用作定位时，SRS资源被serving gNB(或cell)配置在UL active BWP内发送。serving gNB(或cell)向位置服务器发送的SRS配置信息中可包含SRS关联的UL BWP信息，其中，UL BWP信息可以是active UL BWP配置信息和/或所有配置给UE的UL BWPs信息。之后位置服务器可以把SRS关联的UL BWP信息通知或配置给其他参与定位的gNBs(或cells)。
当UL BWP切换时，serving gNB指示位置服务器新的UL BWP配置或新的UL BWP ID信息，以及新的BWP的时域配置信息，之后位置服务器将这些信息通知给参与定位的其他gNBs。或者，serving gNB直接通过Xn接口直接向参与定位的其他gNBs指示新的UL BWP配置或新的UL BWP ID信 息，以及新的BWP的时域配置信息。
进一步地，所述用于定位的上行资源可不限于SRS，还可以是其他上行定位参考信号或上行定位资源。
方法2：上行定位时，网络网络设备为UE配置专门的用于定位的UL BWP，可以被称为‘UL positioning BWP’。根据配置信息，UE在‘UL positioning BWP’内发送用于定位的SRS资源。
进一步地，‘UL positioning BWP’的最大带宽与UE的能力有关，网络设备可以根据UE上报的能力信息获得‘UL positioning BWP’的最大带宽，配置该‘UL positioning BWP’的频域范围。进一步地，‘UL positioning BWP’可以被配置在active UL BWP的外部。进一步地，‘UL positioning BWP’的频域范围可以在UL BWP配置内或UL BWP配置外。具体的，UE可以被配置最多4个BWP，在UL BWP配置内是指‘UL positioning BWP’的频域范围不超过这4个BWP一起占用的频域范围。
进一步地，‘UL positioning BWP’的配置信息中可以包含BWP ID、numerology信息、带宽信息、频域位置、SRS资源关联的配置信息等。网络设备需要把‘UL positioning BWP’的配置信息上报给位置服务器，位置服务器要把这些‘UL positioning BWP’关联的信息通知/配置给其他参与定位的gNBs(或cells)。
进一步地，‘UL positioning BWP’的配置信息中可以包含BWP ID、numerology信息、带宽信息、频域位置、SRS关联的配置信息等。网络设备需把‘UL positioning BWP’的配置信息上报给位置服务器，位置服务器要把这些‘UL positioning BWP’关联的信息通知/配置给其他参与定位的gNBs(或cells)。
进一步地，当网络设备配置SRS资源用于上行定位时，如果‘UL positioning BWP’被分配在当前UL BWP内且numerology与当前BWP相同，则UE无需切换到‘UL positioning BWP’；否则，网络设备指示UE切换到‘UL positioning BWP’上。当上行定位结束或终止时，如果当前BWP为‘UL positioning BWP’，网络设备指示UE切换到新的‘UL BWP’上；否则UE无需切换BWP。当BWP切换发生时，网络设备需将BWP切换信息上报给位置 服务器，之后位置服务器通知或配置给其他参与定位的gNBs(或cells)。
进一步的，所述用于定位的上行资源可不限于SRS，还可以是其他其他上行定位参考信号或上行定位资源。
方法三：上行定位时，UE假设配置给UE的用于定位的SRS配置信息与配置给UE的UL BWP(s)无关，该UE行为可以是网络指示或协议规定。进一步地，SRS资源的带宽与numerology可以不受BWP的限制。进一步地，SRS资源的最大带宽与UE能力有关，网络设备可以根据UE上报的能力信息中终端可支持的最大上行发送带宽，配置该SRS资源的频域范围。进一步地，该SRS资源的频域范围可以在UL BWP配置内或UL BWP配置外。根据网络设备配置，UE发送该用于定位的SRS资源。
进一步地，当UL BWP切换时，UE可以一直发送该SRS资源。或者，当UL BWP切换时，UE停止发送该SRS资源。
进一步地，所述用于定位的上行资源可不限于SRS资源，还可以是其他其他上行定位参考信号或上行定位资源。
