值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址 (Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结果示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的信号传输方法200的流 程示意图，该方法200可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，根据第一子带的资源类型，确定所述第一子带为可用资源或不可用资源。
其中，所述第一子带的资源类型包括上行(Up，U)、下行(Down，D)或灵活(Flexible，F)。需要注意，网络侧按一定的频域宽度进行频域资源方向的指示，该频域宽度在本申请实施例中可称为子带、资源块集(Resource Block set，RB set)或资源单元集(Resource Element set，RE set)。也就是说，子带在本申请中也可以理解为RB set或RE set。
一种实现方式中，所述第一子带的资源类型可通过第一指示信息进行指示；其中，所述第一指示信息包括高层信令(如RRC等)、媒体访问控制控制单元(Medium Access Control-Control Element，MAC CE)、下行控制信息(Downlink Control Information，DCI)中的至少一个。本实施例中，位于不同时间单元(如时隙、子时隙、符号、帧等)上的所述第一子带的资源类型可以不同，也可以相同，在此不做限制。
另一种实现方式中，所述第一指示信息的发送时间早于所述第一信号的发送时间，且所述第一指示信息的发送时间与所述第一信号的发送时间之间具有第一时间差；换言之，以第一信号为SRS为例，网络侧可在SRS发送时刻之前的T时刻发送第一指示信息，以指示所述第一子带的资源类型，进而使得所述终端可以基于第一子带的资源类型确定所述第一子带是可用资源或不可用资源。
另外需要理解，所述可用资源是指能够用于第一信号传输的资源，相应的，所述不可用资源是指不能够用于第一信号传输的资源。
S220，在所述第一子带为可用资源的情况下，基于所述第一子带进行第一信号的传输。
其中，所述第一信号包括但不限于SRS和/或CSI-RS等。相应的，根据第一信号的不同，所述终端可以基于第一子带进行信号的接收、发送等。
本实施例中，终端根据网络配置或指示的子带的资源类型(如资源方向)，确定是否在该子带上进行信号的传输，由此，能够解决对于全双工网络或灵活双工网络中存在的，只能在部分频率资源上进行SRS和/或CSI-RS等信号传输而导致信号传输效率低的问题，确保无线通信性能。
如图3所示，为本申请一示例性实施例提供的信号传输方法300的流程示意图，该方法300可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，根据第一子带的资源类型，确定所述第一子带为可用资源或不可用资源。
可以理解，S310的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，S310中所述的“根据第一子带的资源类型，确定所述第一子带为可用资源”的实现过程，可以包括但不限于以下方式一、方式二中的至少一项。
方式一：在所述第一信号包括SRS、且所述第一子带的资源类型为上行和/或灵活的情况下，确定所述第一子带为可用资源。
例如，假设所述第一子带为可用资源、且资源类型为上行，所述终端可在资源类型为上行的第一子带上进行SRS的发送，也就是，所述终端不在资源类型为下行或灵活的第一子带上进行SRS的发送。
又例如，假设所述第一子带为可用资源、且资源类型为灵活，所述终端可在资源类型为灵活的第一子带上进行SRS的发送，也就是，所述终端不在资源类型为下行的第一子带上进行SRS的发送。
方式二：在所述第一信号包括CSI-RS、且所述第一子带的资源类型为下行和/或灵活的情况下，确定所述第一子带为可用资源。
例如，假设所述第一子带为可用资源、且资源类型为下行，那么，所述终端可在资源类型为下行的第一子带上进行CSI-RS的接收，也就是，所述终端不在资源类型为上行或灵活的第一子带上进行CSI-RS的接收。
又例如，假设所述第一子带为可用资源、且资源类型为灵活，那么， 所述终端可在资源类型为灵活的第一子带上进行CSI-RS的接收，也就是，所述终端不在资源类型为上行的第一子带上进行CSI-RS的接收。
S320，在所述第一信号包括SRS、且配置有至少一组SRS配置的情况下，基于被确定为可用资源的所述第一子带，从至少一组所述SRS配置中选取目标SRS配置。
其中，至少一组所述SRS配置可以由网络侧配置，使得终端可基于被确定为可用资源的子带，确定发送SRS所使用的目标SRS配置。本实施例中，所述目标SRS配置满足以下(1)-(3)中至少一项。
(1)所述目标SRS配置中的SRS资源均位于被确定为可用资源的第一子带内。
(2)所述目标SRS配置中的SRS资源占用的资源数是至少一组所述SRS配置中最大的SRS配置。
其中，所述资源数可以为子带数、RB数、RE数中的任一项。本实施例中，SRS配置中包括的资源数最大也可以理解为SRS配置中的SRS资源占用的带宽最大。
需要注意，假设用于确定各组所述SRS配置中的SRS资源占用的资源数的子带为第三子带，那么，所述第三子带中可以包括连续的多个子带，且该连续的多个子带中不包括被确定为不可用资源的子带。换言之，在进行目标SRS配置选取时，仅考虑连续子带，且该连续子带中不包含被确定为不可用资源的子带。
(3)所述目标SRS配置是至少一组所述SRS配置中具有第二指定索引值的SRS配置。
其中，所述第二指定索引值包括各所述SRS配置分别具有的索引中的最大索引值或最小索引值，本实施例中，所述第二指定索引值可由协议约定或高层信令配置等，在此不做限制。
S330，在所述第一子带为可用资源的情况下，基于所述第一子带进行第一信号的传输。
其中，所述第一信号包括SRS和/或CSI-RS。
可以理解，S330的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，S330中所述的“基于所述第一子带进行第一信号的传输”的实现过程可以包括：在确定有多个第一子带为可用资源的情况下，基于第二子带进行所述第一信号的传输。
其中，所述第二子带为以下(1)-(2)中至少一项。
(1)所述第二子带为多个所述第一子带中的连续子带。在此情况下，所述终端在连续子带上发送SRS。应注意，多个连续子带中不包含被确定为不可用资源的子带。此外，所述连续子带中包括的子带的数量在此不做限制。
(2)多个所述第一子带中具有第一指定索引值的子带。其中，所述第一指定索引值包括多个所述第一子带的索引值中的最大索引值或最小索引值。在此情况下，终端在具有索引最小值的子带上进行SRS的发送。可以理解，具有第一指定索引值的子带可以有一个或多个，在此不做限制。
基于对前述方法实施例300的描述，为了便于理解，下面进一步结合图3b、图3c对本实施例中给出的信号传输流程进行说明，内容如下。
假设网络侧配置了用于终端发送SRS的多组SRS配置，在该时间单元(如符号)上，有部分的子带被指示为不可用资源，所述不可用资源可以是因为网络指示该子带的资源类型为下行或者灵活(如图3b、图3c中的“D”)，则终端不在该子带上进行SRS的发送。
在此情况下，再次参阅图3b所示，终端从配置的多组SRS配置中目标SRS配置，行SRS的发送，如索引最小(也可以理解为索引最低)的SRS配置；又如，对应两个连续子带的SRS配置。可以理解，由于图3b所示的跨多子带的SRS配置中包括不可用资源，因此，不能作为目标SRS配置。
或者，另一种实现方式中，网络侧预先配置用于SRS发送的多组SRS配置，终端进一步根据网络对子带的资源类型的配置或者指示，确定用于SRS发送的目标SRS配置。
例如，请结合参阅3c，假设网络侧配置了3个SRS配置(config)在不同的频域资源上传输，但传输的时域资源(如图3c中所示的时间单元)是相同的，即周期和偏移值相同。假设使用SRS config#1进行SRS发送存在不可用资源(如图3c中所示“D”)的子带的情况下，终端可以选取其他SRS config进行SRS的发送。如选取索引值最小的SRS config，例如SRS config#2，其中，该SRS config#2为不包含不可用资源的SRS config；或者，终端使用连续传输的子带最多的SRS config，例如SRS config#3可以在2个子带上进行SRS传输，而SRS config#2只能在1个subband上进行SRS传输，则终端选择SRS config#3进行SRS传输。
本实施例中，终端在部分资源不可用的情况下，可以确定可用的频域资源进行SRS的发送，由此实现SRS信号的有效传输。
如图4所示，为本申请一示例性实施例提供的信号传输方法400的流程示意图，该方法400可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法400至少可以包括如下步骤。
S410，根据第一子带的资源类型，确定所述第一子带为可用资源或不可用资源。
其中，S410的实现过程可参照前述方法实施例200和/或300中的相关描述，为避免重复，在此不再赘述。
S420，在所述第一信号包括所述SRS、且配置有至少一组SRS配置的情况下，根据第一SRS配置或者所述第一SRS配置的带宽，确定用于所述SRS传输时的目标发送功率。
其中，所述第一SRS配置属于至少一组所述SRS配置。本实施例中，所述第一SRS配置，可以理解为：终端可以以第一SRS配置对应的功率进行SRS的发送。可选地，所述第一SRS配置可以包括以下(1)-(3)中之一。
(1)由协议约定或网络指示的参考SRS配置。
(2)带宽为指定值的SRS配置；其中，所述指定值可由协议约定或网 络侧配置，在此不做限制。
(3)索引值为第三指定索引值的SRS配置。其中，所述第三索引值可由协议约定或网络侧配置，在此不做限制。
一种实现方式中，S420中所述的“根据所述第一SRS配置或者所述第一SRS配置的带宽，确定目标发送功率”的实现过程可以包括以下方式一或方式二。
方式一：在被确定为可用资源的第一子带中包括的资源数小于所述第一SRS配置中的SRS占用的资源数的情况下，确定所述第一SRS配置对应的发送功率为所述目标发送功率。其中，所述资源数为子带数、RB数、RE数中的任一项。
例如，如果第一SRS配置或者第一SRS配置的带宽占用4个subband，实际发送的带宽的发送带宽只占用2个subband，那么，终端可在2个Subband上的SRS发送功率与根据第一SRS配置在4个subband上发送的总发送功率相同。也就是，每个资源单元的能量(Energy per resource element，EPRE)是原先的2倍。
在本方式一中，由于终端发送SRS时实际占用的频域资源变小，则终端发送的SRS的EPRE(每个资源单元的能量)相比于第一SRS配置变大。也就是，终端可以用更大的EPRE进行SRS的发送，在部分子带的SRS无法发送的情况下，在被确定为可用资源的子带上的发送SRS的EPRE提高，可以保证网络可以获得更精确的上行测量结果、信道质量判断结果等。
方式二：在被确定为可用资源的第一子带中包括的资源数小于所述第一SRS配置中的SRS占用的资源数的情况下，按照预定比例对所述第一SRS配置对应的总发送功率进行缩放，得到所述目标发送功率，其中，所述预定比例根据被确定为可用资源的第一子带中包括的资源数以及所述第一SRS配置中的SRS占用的资源数确定。其中，所述资源数为子带数、RB数、RE数中的任一项。
例如，如果被确定为可用资源的子带中包括的资源数小于第一SRS配 置中包括的资源数，或者被确定为可用资源的子带的带宽小于第一SRS配置的带宽，那么，所述终端对第一SRS配置对应的总发送功率进行缩放，保证发送的EPRE相同。
在本方式二中，由于终端发送SRS时实际占用的频域资源变小，则终端在该时间单元上的总发送功率变小。也就是说，终端保持SRS的EPRE恒定，无论终端发送的子带的带宽大小，网络侧接收该SRS时，无需根据带宽的大小，对接收功率进行转换，再进行测量和信道质量判断等。
S430，在所述第一子带为可用资源的情况下，基于所述第一子带进行第一信号的传输。
其中，所述第一信号包括SRS和/或CSI-RS。
可以理解，S430的实现过程除了可参照前述方法实施例200和/或300中的相关描述之外，作为一种可能的实现方式，S430中所述的“基于所述第一子带进行第一信号的传输”的实现过程可以包括图4所示的S431，内容如下。
S431，基于所述第一子带，以所述目标发送功率进行所述第一信号的传输。
本实施例中，终端对发送SRS所采用的发送功率进行控制，由此，能够进一步实现SRS信号的高效传输，同时，使得网络侧可根据终端采用的不同的功率控制方式，实现更加精确的上行测量、信道质量判断等，确保了无线通信性能。
如图5a所示，为本申请一示例性实施例提供的信号传输方法500的流程示意图，该方法500可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法500至少可以包括如下步骤。
S510，根据第一子带的资源类型，确定所述第一子带为可用资源或不可用资源；
S520，在所述第一子带为可用资源的情况下，基于所述第一子带进行第一信号的传输。
其中，所述第一信号包括SRS和/或CSI-RS。
可以理解，S510和S520的实现过程可参照前述方法实施例200-400中的至少一个的相关描述，为避免重复，在此不再赘述。
S530，所述终端在第一时间单元上接收所述CSI-RS、但所述第一时间单元上的时域资源中存在部分频域资源是不可用资源的情况下，执行预定操作。
其中，第一时间单元可以是时隙、符号、子帧等，且所述第一时间单元可通过协议约定或网络配置，在此不做限制。
所述部分频域资源中包括至少一个子带和/或位于子带之间的保护带。可以理解，在网络全双工或者灵活双工的情况下，为了避免上下行之间的干扰，会在上行和下行的频域资源之间引入保护带，以避免上下行之间的干扰。例如，对于成对频谱之间的保护带，是上行载波和下行载波之间的保护间隔。又例如对于非成对频谱，在相同的时间单元内，不同的子带的传输方向不同，在子带内也需要引入保护间隔，即引入载波内的子带之间的保护带。
一种可能的实现方式中，所述不可用资源包括以下(1)-(3)至少之一。
(1)资源类型为上行或灵活的子带。
(2)保护带。
(3)包括的资源数小于预定值的子带，所述资源数为RB数或RE数。所述预定值可通过协议约定或网络侧配置，例如某个子带包括的资源数小于预定值，则该子带为不可用资源。
在此情况下，如果用于CSI-RS接收的第一时间单元上，存在部分频域资源不可用，那么，所述终端可以执行所述预定操作，本实施例中，所述预定操作包括以下(1)-(4)中至少一项。
(1)不上报所述CSI-RS对应的CSI报告。也就是说，在存在部分频域资源不可用的情况下，所述终端不进行CSI报告上报。
(2)上报第一CSI-RS对应的第一CSI报告，所述第一CSI-RS是通过所述第一时间单元上的、被确定为可用资源的第一子带接收到的CSI-RS。也就是说，所述终端只上报在基于被确定为可用资源的子带上接收的CSI-RS确定的CSI报告。
(3)上报所述CSI-RS对应的CSI报告中的超出预定范围的参数值(也就是，out-of-range，OOR)。本实施例中，所述预定范围可以是但不限于信道质量指示(Channel quality indicator，CQI)的范围，例如，OOR可以是CQI＝0。
(4)上报第二CSI报告，所述第二CSI报告是所述终端上一次上报的CSI报告。换言之，终端不更新CSI报告，并再次上报未更新的上一次上报的CSI报告。
需要注意，前述的CSI-RS包括宽带CSI-RS、子带CSI-RS中的至少之一。所述子带CSI-RS可以包括最优的X个子带和最差的Y个子带。
另外，前述CSI报告上报中，如上报宽带CSI-RS对应的CSI报告，那么，可通过被确认为可用资源的第一子带上报所述CSI报告。例如，对于不考虑不可用资源的情况，假设有4个子带，就基于4个子带确定CSI报告；相反，对于考虑不可用资源的情况下，假设4个子带中至少有3个子带为可用资源，那么，可基于可用资源的子带确定CSI报告。其中关于CSI报告的确定过程在此不再赘述。
前述实现方式中，用于CSI报告上报的子带，可以与基于网络频域资源划分的子带相同，也可以不同，在此不做限制。
为便于理解，下面以CSI-RS的接收、CSI报告的上报为例，对本实施例给出的信号传输过程进行说明，内容如下。
终端基于被确定为可用资源的子带(即前述的第一子带)进行CSI-RS的接收、或者进行相应的CSI report的发送。具体的，如图5b所示，由于部分频域资源被网络侧配置(或指示)为上行(如图5b中的“U”)或者灵活(如图5b中的“F”)，因此，网络侧为CSI-RS资源配置宽带配置，如图 5b中所示的跨多个子带(RB set)的BWP，在此情况下，终端只接收多个子带中被确定为可用资源的子带上传输的CSI-RS，并基于接收CSI-RS的子带进行CSI报告的上报。
其中，假设终端在第一时间单元接收CSI-RS，那么，如果第一时间单元上的所有子带都可用，例如资源类型都是下行或者灵活(如图5c中所示的第一时间单元#2)，则终端可基于所有的子带上的CSI-RS资源进行宽带CSI的测量和上报，终端在CSI测量和上报时，排除保护带中的CSI-RS对应的RE资源。
如果第一时间单元对应的频域资源中存在至少有一个子带为不可用资源(如图5c中所示的第一时间单元#1)，则终端不进行CSI上报，或者，终端上报OOR，或者，终端基于被确定为可用资源的subband内接收的CSI-RS进行CSI测量和上报。
如果网络侧同时配置了终端进行子带CSI的上报，如果子带CSI对应的频域资源中，至少有一个RE为不可用资源或者位于保护带中，则终端不在该子带上进行CSI上报，即只上报可用的CSI-RS资源对应的CSI报告。例如CSI子带1、2、x中，子带x不可用，则上报宽带的CSI报告和除第x个子带之外的其他子带的CSI报告；或者，所述终端仍然进行CSI上报，但是对应的子带CSI中包括OOR。
对于子带CSI的上报，由于CSI上报的子带的划分，和网络侧进行频域资源方向(也即资源类型)配置或者指示的颗粒度RB set的宽度不同，则有可能部分子带CSI上报对应的CSI-RS的资源全部或者部分为有效的CSI-RS，即在下行或者灵活的subband内，另一部分为不可用的CSI-RS资源，即在不可用RB set内或者在guardband内，则终端认为该子带的CSI-RS资源不是子带CSI上报的可用测量资源。
如果可用的CSI-RS的RE、RB数占比超过预定值，则认为是子带CSI上报的可用测量资源。
需要说明的是，OOR对应为CSI的上报量中的CQI＝0；对于其他的上 报值，例如秩指示(Rank indicator，RI)、预编码矩阵指示(Precoding matrix indicator，PMI)、CSI-RS资源指示(CSI-RS Resource Indicator，CRI)、L1参考信号接收功率(Layer 1reference signal received power，L1-RSRP)、L1信号与干扰加噪声比(Layer 1 signal-to-noise and interference ratio，L1-SINR)，也可以定义预定值，当CSI-RS资源不可用时，对应的CSI上报中的相应的上报值采用该预定值。
由于网络侧可能通过动态信令(例如通过PDCCH指示)指示部分subband为不可用资源，即取消了对应的频域资源上的CSI-RS的发送，部分的CSI-RS对应的CSI测量值无法获取。由于一个CSI上报中包含多个subband CSI上报，或者一个PUCCH/PUSCH中包含了多个CSI report。
如果终端不上报对应的(子带)CSI报告，而网络侧不清楚终端是否接收到该动态信令，那么终端在收到该信令或者没有收到该信令的情况下，发送的CSI的比特数不同，则网络侧无法获知终端实际发送的比特数，在这种情况下，通过发送OOR或者其他预设信息的情况下，通过仍然发送这些无效CSI-RS资源对应的上报，可以简化网络侧的接收CSI报告的复杂度。
或者，终端只发送其中的有效的CSI-RS资源对应的CSI report并显示(CSI report中携带额外的信令比特)或隐式(发送CSI report所使用的时域/频域/DMRS的资源不同)的告知基站发送的CSI report对应的是哪些有效的CSI-RS资源，则可以降低上行发送的开销，提升CSI接收的性能。
本实施例中，终端进一步在部分资源不可用的情况下，确定CSI-RS接收流程、CSI报告的上报方式，以进行确保CSI-RS、CSI报告的有效传输。
