Description

检测窗的获取方法、装置及终端
相关申请的交叉引用
本申请主张在2020年8月7日在中国提交的中国专利申请号No.202010791656.5的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域,具体涉及一种检测窗的获取方法、装置及终端。
背景技术
长期演进(Long Term Evolution,LTE)系统支持旁链路(sidelink)传输,即终端(也称为用户设备User Equipment,UE)之间直接在物理层上进行数据传输。LTE sidelink是基于广播进行通讯的,虽然可用于支持车联网(vehicle to everything,V2X)的基本安全类通信,但不适用于其他更高级的V2X业务。5G新空口(New Radio,NR)系统将支持更加先进的sidelink传输设计,例如,单播,多播或组播等,从而可以支持更全面的业务类型。
在LTE中,部分检测主要是为了省电而设计的,是为了支持行人和车(Pedestrian to Vehicle,P2V)之间的通信。终端支持两种模式的资源选择方式。一种为随机的资源选择,另一种为先进行部分检测,基于部分检测的结果选择资源,进行半静态的资源预留。其中终端选择哪种模式的资源选择方式是无线资源控制(Radio Resource Control,RRC)配置的,当RRC配置为支持两种模式的资源选择时,终端决定采用哪种资源选择方式。
在实现本申请过程中,发明人发现现有技术中至少存在如下问题:
在LTE sidelink中,sidelink资源池中部分检测的步长固定为100ms,对于LTE中的周期配置来说,k*100ms获取的检测窗基本可以检测出资源池中其他UE的资源预留情况。但是,在NR中,检测周期可选值并不规律,若以100ms为步长获取检测窗,会导致无法检测到选择窗口内其他终端(例如预留周期为[1:99]的终端)的资源预留情况,导致该检测终端在进行资源选择时, 选择的资源会与其他终端预留的资源碰撞。
发明内容

若该资源池中支持部分检测,则终端在该资源池中进行部分检测时,采用步长P1=80,和步长P2=100获取资源检测窗口的位置。
示例三
预定义终端根据资源池中配置周期的量化结果获取检测步长。预定义量化粒度为10ms,且量化方法采用四舍五入获取量化值。预定义存在100*k的周期值时,一个步长值P=100。若存在周期值属于[1:99]的周期值时,根据周期值的量化值取最小公倍数,为另一个步长值。

若该资源池中终端支持部分检测,则所述终端采用步长P1=80,和步长P2=100获取资源检测窗口的位置。
示例四
预定义若资源池配置的非零周期值中存在小于高层配置的周期门限值,则在该资源池中,终端采用第二资源检测窗口检测资源。否则,终端根据资源池中的配置的周期值获取步长P,根据步长P确定资源检测窗口进行资源检测。
