如图1所示，本公开实施例提供的一种传输保护时间间隔信息的方法可应用于无线通信系统100，该无线通信系统可以包括但不限于网络设备101和用户设备102。用户设备102被配置为支持载波聚合，用户设备102可连接至网络设备101的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景，也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th-Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。

其中，用户设备102可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理personal digital assistant， PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备101可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备具体可包括基站(base station，BS)设备，或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备可以是可穿戴设备或车载设备。网络设备也可以是具有通信模块的通信芯片。

在一些可能的实施方式中，用于SRS资源切换的SRS资源间的切换保护间隔采用整数个字符(symbol)的形式的设置。根据不同的载波支持的子载波间隔(SubcarrierSpacing，SCS)，对应不同的字符个数。然而，在更高的频率段(例如毫米波频段，甚至太赫兹频段)，终端支持的SCS不断增大，例如可以达到480kHz，960kHz等，相应的保护间隔也需要相应的增大，相应的造成逐渐增大的资源开销。
如果网络设备可以获知每个用户设备的切换能力，便可以根据不同的用户设备的不同的切换能力，为具有不同切换能力的用户设备进行更合理的配置。
在一组SRS资源集中，配置多个SRS资源，不同的SRS资源对应于不同的终端天线端口以进行不同终端天线到达基站的路径评估，因此在SRS资源切换的时候，终端需要进行终端天线的物理切换，在完成切换之前，终端无法进行SRS资源的传输，需要根据终端的能力配置相应的保护间隔。
