Description

定时参量确定方法、装置、设备和存储介质
本申请要求在2020年04月02日提交中国专利局、申请号为202010256349.7的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信网络领域，例如涉及一种定时参量确定方法、装置、设备和存储介质。
背景技术
随着无线电技术的不断进步，各种各样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，传统的商业通信主要使用的300兆赫兹(MHz)-3吉赫兹(GHz)之间频谱资源表现出极为紧张的局面，已经无法满足未来无线通信的需求。
在新一代无线通信系统中，例如在新空口(New Radio，NR)系统或第五代移动通信(the 5th Generation Mobile Communication，5G)系统，5G之后的新一代无线通信系统中，将会采用比第四代移动通信(the 4th Generation Mobile Communication，4G)系统所采用的载波频率更高的载波频率进行通信，例如采用28GHz、45GHz、70GHz等等。这种高频信道具有自由传播损耗较大，容易被氧气吸收，受雨衰影响大等缺点，严重影响了高频通信系统的覆盖性能。
由于高频通信对应的载波频率具有更短的波长，可以保证单位面积上能容纳更多的天线元素，而更多的天线元素意味着可以采用波束赋形的方法来提高天线增益，从而保证高频通信的覆盖性能。其中，密集小区是越来越主要的应用场景，而密集小区将需要更多的网络部署成本，引入无线回程传输可以很容易地进行部署网络，并且大幅降低网络部署成本。此外NR系统包括高频频段，所以高频载波物理特性决定，其覆盖范围是非常大的挑战，无线回程传输也可以解决这个问题。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在NR系统中，已经针对统一的接入和回程(Integrated Access and Backhaul，IAB)进行了立项。为了便于描述，定义了几种标记(L P,DL，L P,UL)，(L C,DL，L C,UL)，(L A,DL，L A,UL)。其中，(L P,DL，L P,UL)表示节点和父节点之间的下行链路和上行链路，该链路可看作是回程链路(Backhaul link，BL)，所述节点可看作是所述父节点的子节点。(L C,DL，L C,UL)表示节点和子节点之间的下行链路和上行链路，该链路可看作是BL，所述节点可看作是所述子节点的父节点。(L A,DL，L A,UL)表示节点和用户设备之间的下行链路和上行链路，该链路可看作是接入链路(Access link，AL)。其中，父节点也可为施主节点(Donor Node，DN，包括Donor gNB)。同时为了克服半双工中继节点在带内(in-band)场景下带来的收发自干扰问题，提出BL和AL之间采用如下复用方式：时分复用 (Time Division Multiplexing，TDM)、频分复用(Frequency Division Multiplexing，FDM)、空分复用(Spatial Division Multiplexing，SDM)，其中，TDM表示BL和AL之间采用不同的时间资源，SDM表示BL和AL之间采用不同的波束资源，FDM表示BL和AL之间采用不同的频率资源。还针对中继节点(Relay Node，RN也称为IAB Node)定义了两种功能，即IAB Node移动终端((Mobile Terminal，MT)和IAB Node分布单元(Distributed Unit，DU)。
为了保持网络同步，从而减少节点间相互干扰，要求各个节点间需要保持下行发射定时(Downlink Transmit Timing，DL Tx Timing，DTT)对齐。原则上只要子节点基于子节点下行接收定时(DL Receive Timing，DL Rx Timing，DRT)向前提前TA/2，其中，TA可以是时间提前量(Timing Advance)。即可获取子节点DTT＝DRT-TA/2，则可以保持节点间DTT对齐。但由于父节点侧实现等原因，导致父节点上行接收定时(Uplink Rx Timing，UL Rx Timing，URT)和父节点DTT之间存在偏移，所以子节点不能简单地认为子节点DTT＝DRT-TA/2是实际的子节点DTT，合理的应该是子节点通过计算(TA/2+T delta)获取父节点DTT和子节点DRT之间的时间差，则合理的子节点DTT＝DRT-(TA/2+T delta)。其中，父节点上行接收和下行发射对齐可以参考图1a，父节点上行接收和下行发射不对齐可以参考图1b。
在一个示例性的实施方式中，图1c是本申请实施例提供的一种定时参量确定方法流程图，该方法可以由定时参量确定装置来执行，所述装置可以由软件和/或硬件来实现，所述装置可以集成在节点设备上。

在一个示例性的实施方式中，可以通过配置的方式确定子载波间隔。
例如，直接配置子载波间隔，配置的子载波间隔作为确定的子载波间隔， 或，例如，间接配置子载波间隔，配置上行链路部分宽带标识(Uplink Bandwidth Part Identifier，UL BWPID)为“01”，则“01”对应的UL BWP的子载波间隔作为确定的子载波间隔，或，例如，间接配置子载波间隔，配置下行链路(Downlink，DL)载波(carrier)ID为“00001”，则“00001”对应的DL carrier的子载波间隔作为确定的子载波间隔。
使用上述确定的子载波间隔进行定时参量的计算或查表。
在一个示例性的实施方式中，可以通过默认的方式确定子载波间隔。
例如，定时参量索引对应信令承载在DL BWP ID为“01”的DL BWP上，“01”对应的DL BWP的子载波间隔作为确定的子载波间隔，或，例如，定时参量索引对应信令承载在DL carrier ID为“00001”的DL carrier上，“00001”对应的DL carrier的子载波间隔作为确定的子载波间隔，或，例如，存在2个激活的UL BWP ID为“01”和UL BWP ID为“10”，这两个UL BWP可以属于相同UL carrier，也可以属于不同UL carrier，“01”对应的UL BWP的子载波间隔和“10”对应的UL BWP的子载波间隔中最小值作为确定的子载波间隔，或，例如，存在2个激活的UL carrier ID为“00001”和UL carrier ID为“00010”，“00001”对应的UL carrier的子载波间隔和“00010”对应的UL carrier的子载波间隔中最小值作为确定的子载波间隔。
使用上述确定的子载波间隔进行定时参量的计算或查表。
在一个示例性的实施方式中，可以通过默认的方式确定频率范围。
如果确定的子载波间隔对应的频率范围不同，则确定频率范围为频率范围1或频率范围2。
例如，在IAB node MT或IAB node DU侧，如果有多个激活的UL BWP，且这些BWP具有相同的子载波间隔(例如为60kHz)，且该子载波间隔是所有激活的UL BWP的子载波间隔的最大或者最小值，但这些BWP对应多个不同的频率范围，则确定频率范围为频率范围1或频率范围2。
所述多个激活的UL BWP可以属于同一个小区，如发射定时参量索引对应信令的服务小区，也可以属于不同的小区，例如一个TAG中的多个小区。
使用上述确定的子载波间隔、确定的频率范围进行定时参量的计算或查表。

其中，L表示定时参量范围的下界，U表示定时参量范围的上界。L Δf表示Δf对应的除-N TA,offset/2分量之外的定时参量范围的下界，U Δf表示Δf对应的除-N TA,offset/2分量之外的定时参量范围的上界。

在一个示例性的实施方式中，不同子载波间隔对应不同定时参量索引信令开销。
每个Δf对应的T D的信令开销O B＝log 2((U Δf-L Δf)/N G)，例如，Δf为15kHz的L 15＝-128T c，U 15＝128T c，N G＝64T c；Δf为30kHz的L 30＝-64T c，U 30＝64T c，N G＝64T c；则，Δf为15kHz对应的T D的信令开销O B＝log 2((U Δf-L Δf)/N G)＝log 2((128-(-128))/64)＝2比特；Δf为30kHz对应的T D的信令开销O B＝log 2((U Δf-L Δf)/N G)＝log 2((64-(-64))/64)＝1比特。
在一个示例性的实施方式中，不同子载波间隔对应相同定时参量索引信令开销。
每个Δf对应的T D的信令开销O B＝max(log 2((U Δf-L Δf)/N G))，其中，max表示取最大值，例如，Δf为15kHz的L 15＝-128T c，U 15＝128T c，N G’＝64T c；Δf为30kHz的L 30＝-64T c，U 30＝64T c，N G＝64T c；则，Δf为15kHz、30kHz对应的T D的信令开销O B＝max(log 2((U Δf-L Δf)/N G))＝max(log 2((128-(-128))/64),log 2((64-(-64))/64))＝max(2,1)＝2比特。
在一个示例性的实施方式中，可以是统一的定时参量索引信令开销。
所有Δf对应的T D的信令开销O B＝log 2((U Δf-L Δf)/N G)，例如，L 15＝L 30＝L 60＝L 120＝0T c，U 15＝U 30＝U 60＝U 120＝65535·N G，N G＝32T c；则，所有Δf对应的T D的信令开销O B＝log 2((U Δf-L Δf)/N G)＝log 2((65535·32-0)/32)＝16比特。
在一个示例性的实施方式中，子载波间隔决定的定时提前量颗粒度为16·64T c/2 μ。

节点不对12·64T c就定时提前值的集合set_0内的定时提前值就近取定时提前量颗粒度16·64T c的整数倍，即节点不对12·64T c向下或向上调整到接近定时提前值的集合set_0内的定时提前值为0·64T c、16·64T c，即节点仍然保持定时提前量为12·64T c。
