Description

一种窗口调整方法及装置、网络设备、终端 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种窗口调整方法及装置、网络设备、终端。
背景技术
对于非授权频段的随机接入过程,用户设备(UE,User Equipment)监听Msg2的时间窗口(称为RAR window)里,如果基站针对Msg2的发送做先听后说(LBT,Listen Before Talk)时持续侦听失败,则UE会由于在随机接入响应窗口(RAR window)内没有收到Msg2而导致随机接入失败,此时UE需要重新发起随机接入过程,而这个重新发起的随机接入过程会引入更多的LBT操作,带来较大的随机接入时延和不确定性。
此外,上述问题在基站收到Msg3后准备回复Msg4时同样存在,比如基站针对Msg4的发送做LBT时连续侦听失败,则UE会由于在竞争解决定时器有效时间内没有收到Msg4而导致随机接入失败,此时UE需要重新发起随机接入过程,而这个过程的重新发起涉及到整个Msg1、Msg2、Msg3、Msg4的重新LBT和发送,带来更大的随机接入时延和不确定性。

为便于理解本申请实施例的技术方案,以下对本申请实施例涉及到的相关技术进行说明。
1)授权频段随机接入工作机制
参照图2(a),授权频段的竞争随机接入过程包括如下步骤:
(1)UE发送Msg1,并在RRC信令配置的时间窗口内监听Msg;
(2)基站收到Msg1后,反馈Msg2;
(3)UE收到Msg2后获得上行授权,继而基于上行授权发送Msg3,并在竞争解决定时器失效前监听Msg4;
(4)基站收到Msg3后,反馈Msg4。
参照图2(b),授权频段的非竞争随机接入过程包括如下步骤:
(0)基站向UE发送Msg0,通过Msg0给UE做非竞争随机接入所必须的参数配置,例如随机接入前导码配置;
(1)UE基于基站的配置发送Msg1,并在RRC信令配置的时间窗口内监听Msg2;
(2)基站收到Msg1后,反馈Msg2。
2)长期演进授权辅助接入(LTE LAA,Long Term Evolution Licensed Assisted Aceess)和新空口非授权(NR-U,New Radio-Unlicensed)频谱
针对非授权频谱的利用,终端在非授权频谱上传输数据需要满足一些非授权频谱规范的要求的,比如LBT,即终端或者网络在传输数据之前需要侦听信道,如果检测到的能量低于某个门限值,则认为终端可以在该信道上传输数据。
LTE支持载波聚合(CA,Carrier Aggregation)的方式使用非授权频谱,即主小区(PCell,Primary Cell)工作在授权频谱上,提供基本的接入功能,以及数据传输功能,辅小区(SCell,Secondary Cell)工作在非授权频谱上作为数据boosting的目的使用。在LTE LAA工作方式中,随机接入(RA,Random Access)过程在PCell,因此RA功能没有针对非授权(unlicensed)频谱做优化;
NR-U频谱需要支持LAA的方式,同时还有独立组网(stand-alone)的工作方式;对于stand-alone,RA过程也需要在unlicensed频谱上完成,因此,RA需要针对unlicensed频谱的要求做进一步优化,同时也需要满足unlicensed频谱接入的要求,比如LBT。
3)非授权频段下的随机接入过程中的问题
首先,对于非授权频段,在随机接入过程中,在UE监听Msg2的时间窗口(称为RAR window)里,如果基站针对Msg2的发送做LBT时持续侦听失败,则UE会由于在RAR window内没有收Msg2而导致随机接入失败,此时UE需要重新发起随机接入过程,而这个重新发起的随机接入过程会引入更多的LBT操作,带来较大的随机接入时延和不确定性。
其次,为了解决上述问题,如果通过无线资源控制(RRC,Radio Resource Control)信令直接配置更大的RAR window长度,这种方法虽然可以保证基站有更多的LBT机会,但也有弊端。当直接配置较长的RAR window时,如果UE发送的Msg1没有被基站收到,或者基站不期望回复该UE的Msg1时,UE仍然会在所配置较长的RAR window内做Msg2的持续监听,而这种监听是没必要的,且是不利于UE能耗节省的。
此外,上述问题在基站收到Msg3后准备回复Msg4时同样存在,比如基站针对Msg4的发送做LBT时连续侦听失败,则UE会由于在竞争解决定时器有效时间内没有收到Msg4而导致随机接入失败,此时UE需要重新发起随机接入过程,而这个过程的重新发起涉及到整个Msg1、Msg2、Msg3、Msg4的重新LBT和发送,带来更大的随机接入时延和不确定性。同样地,如果采用更大的固定长度竞争解决定时器,则会带来UE的能耗开销问题。
在本申请实施例的技术方案中,上述描述相关的RAR window、竞争解决定时器等监测窗口的相关参数只在有需求的情况下才基于基站指示做出调整,这种方法一定程度上规避了上述弊端。
