Description

随机接入资源配置方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域,特别涉及一种随机接入资源配置方法、装置、设备及存储介质。
背景技术
3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)在5G NR(New Radio,新空口)系统中引入了NTN(Non Terrestrial Network,非地面通信网络)技术。
NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信系统,NTN系统具有很多独特的优点。首先,NTN系统不受用户地域的限制,由于一颗卫星即可以覆盖较大的地面,且卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被NTN系统覆盖。其次,NTN系统有较大的社会价值,NTN系统在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,NTN系统距离远,且通信距离增大通讯的成本没有明显增加。最后,NTN系统的稳定性高,不受自然灾害的限制。
在NTN技术中,针对如何确定UE(User Equipment,用户设备)执行随机接入时所需要的RACH(Random Access Channel,随机接入信道)资源,还需要进一步研究。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案,并不构成对本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
请参考图1,其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括:网络设备 10和终端设备20。
网络设备10是用于为终端设备20提供无线通信服务的设备。网络设备10与终端设备20之间可以通过空口建立连接,从而通过该连接进行通信,包括信令和数据的交互。网络设备10的数量可以有多个,两个邻近的网络设备10之间也可以通过有线或者无线的方式进行通信。终端设备20可以在不同的网络设备10之间进行切换,也即与不同的网络设备10建立连接。
在一个示例中,如图2所示,以NTN网络为例,NTN网络中的网络设备10可以是卫星11。一颗卫星11可以覆盖一定范围的地面区域,为该地面区域上的终端设备20提供无线通信服务。另外,卫星11可以围绕地球做轨道运动,通过布设多个卫星11,可以实现对地球表面的不同区域的通信覆盖。
相比于地面的蜂窝通信网络,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,卫星通信距离远,且通信距离增大通讯的成本没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit,低地球轨道)卫星、MEO(Medium-Earth Orbit,中地球轨道)卫星、GEO(Geostationary Earth Orbit,地球同步轨道)卫星、HEO(High Elliptical Orbit,高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO
低轨道卫星高度范围为500km~1500km,相应轨道周期约为1.5小时~2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短,链路损耗少,对用户终端的发射功率要求不高。
2、GEO
地球同步轨道卫星,轨道高度为35786km,围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量,卫星采用多波束覆盖地面,一颗卫星可以形成几十甚至数百个波束来覆盖地面;一个卫星波束可以覆盖直径几十至上百公里的地面区域。
在另一个示例中,如图3所示,以蜂窝通信网络为例,蜂窝通信网络中的网络设备10可以是基站12。基站12是一种部署在接入网中用以为终端设备20提供无线通信功能的装置。基站12可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备网络设备功能的设备的名称可能会有所不同,例如在5G NR(New Radio,新空口)系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端设备20提供无线通信功能的装置统称为网络设备。
另外,本申请实施例中涉及的终端设备20,可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,本申请实施例中,上面提到的设备统称为终端设备。
另外,在本申请实施例中,名词“网络”和“系统”通常混用,但本领域技术人员可以理解其含义。
请参考图4,在NR Rel-15(Release 15,第15版本)中,主要支持两种随机接入方式,分别为基于竞争的随机接入方式和基于非竞争的随机接入方式。
对于图4所示的基于竞争随机接入过程分为4步,基于非竞争的随机接入过程分为2步。详细的步骤如下:
1、终端设备向网络设备发送Msg1(Message 1,消息1)。
终端设备选择PRACH(Physical Random Access Channel,物理随机接入信道)资源,并在选择的PRACH上发送选择的preamble(前导码)。如果是基于非竞争的随机接入,PRACH资源和preamble可以由网络设备指定。网络设备基于preamble可以估计上行Timing(定时),和终端传输Msg3(Message 3,消息3)所需要的grant(调度)大小。
2、网络设备发送RAR(Random Access Response,随机接入响应)给终端设备。
终端设备发送Msg1之后,开启一个随机接入响应时间窗,在该随机接入响应时间窗内监测RA-RNTI(Random Access Radio Network Temporary Identifier,随机接入无线网络临时标识)加扰的PDCCH(Physical Downlink Control Channel,物理下行控制信道)。RA-RNTI的计算如下:
RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id
即RA-RNTI跟UE发送Msg1所使用的PRACH时频资源有关。
终端设备成功接收到RA-RNTI加扰的PDCCH之后,终端设备能够获得该PDCCH调度的PDSCH,其中包含了RAR(随机接入相应),RAR具体包含以下信息:
RAR的subheader(包头)中包含BI,用于指示重传Msg1的回退时间;
RAR中的RAPID:网络设备响应收到的preamble index(前导码指示);
RAR的payload(载荷)中包含了TAG,用于调整上行定时;
UL grant(Uplink grant,上行调度):用于调度Msg3的上行资源指示;
Temporary C-RNTI(Temporary Cell Radio Network Temporary Identifier,临时小区无线网络临时标识):用于加扰Msg4的PDCCH(初始接入)。
如果终端设备接收到RAR-RNTI(Random Access Response Radio Network Temporary Identifier,随机接入响应无线网络临时标识)加扰的PDCCH,并且RAR中包含了自己发送的preamble index,则终端设备认为成功接收了随机接入响应。
对于基于非竞争的随机接入,终端设备成功接收Msg2(Message 2,消息2)后,随机接入过程结束。对于基于竞争的随机接入,终端设备成功接收Msg2后,还需要继续传输Msg3和接收Msg4(Message 4,消息4)。
3、终端设备在网络设备调度资源上传输Msg3。
Msg3主要用于通知网络设备该RACH(Random Access Channel,随机接入信道)过程是由什么事件触发。比如,如果是初始接入随机过程,则在Msg3中会携带UE标识和establishment cause(建立原因);如果是RRC重建,则会携带连接态UE标识和establishment cause。
4、网络设备向终端设备发送Msg4。
Msg4有两个作用,一个是用于竞争冲突解决,第二是网络设备向终端设备传输RRC配置消息。竞争冲突解决有以下两种方式:一种是如果UE在Msg3中携带了C-RNTI(Cell Radio Network Temporary Identifier,小区无线网络临时标识),则Msg4用C-RNTI加扰的PDCCH调度。另一种是如果UE在Msg3中没有携带C-RNTI,比如是初始接入,则Msg4用TC-RNTI(Temporary Cell Radio Network Temporary Identifier,临时小区无线网络临时标识)加扰的PDCCH调度,冲突的解决是UE接收Msg4的PDSCH(Physical Downlink Shared Channel,物理下行共享信道),通过匹配PDSCH中的CCCH SDU(通用控制信道服务数据单元)。
从以上随机接入的过程可以看出,随机接入的主要目的就是终端设备与网络设备取得上行同步。在随机接入过程中,网络设备接收终端设备的前导码,根据该前导码所使用的随机接入信道的时频资源,可以知道终端发送前导码的时刻,从而根据前导码的发送时刻和接收时刻确定该终端的初始TA(Timing Advance,定时提前)值,并通过随机接入响应中告知终端。
基于目前Rel-16(Release 16,第16版本)NTN标准化讨论,NTN中将支持两种类型的终端设备,一种是没有定位能力的终端设备,一种是有定位能力的终端设备。对于这两种类型的终端设备,初始TA的确定方法有所不同。
对于不具有定位能力的UE,网络设备会基于近地点与网络设备之间的信号传输时延广播1个公共TA,如下图5所示,对于regenerative payload(再生有效载荷),公共TA=2*d0/c;对于bent-pipe payload(弯管有效载荷),TA=2*(d0+d0_F)/c。由于随机接入响应中终端设备会获得真实的TA值,因此网络设备在调度Msg3时会考虑终端设备的真实TA值。
对于具有定位能力的终端,其随机接入过程如下图6所示。
步骤1:终端设备基于定位能力估算自己的TA,并使用自己估算的该TA发送msg1。
步骤2:网络设备在收到Msg1后确定终端设备的TA调整值,并通过Msg2指示给终端设备。由于此时网络设备并不知道终端设备确切的TA值,此时网络设备可以按照最大上行调度时延调度该终端设备的Msg3的资源。
步骤3:终端设备基于接收到的RAR的指示对TA进行调整,并在网络设备调度的上行资源上发送Msg3。
步骤4:网络设备接收到终端设备的Msg3后,就可以知道该终端设备使用的初始TA,自此网络设备和终端设备,对于该终端设备TA值的理解达成一致。
在示例性实施例中,RACH配置由网络设备通过广播形式告知终端设备。RACH配置中包含RACH时频资源配置和起始的前导码根序列配置。
RACH时域资源配置通过1个RACH配置索引指示,通过该RACH配置索引可以获知RACH资源重复周期,一个RACH资源重复周期内包含的RO个数,每个RO的持续时间等。
RACH频域资源配置包括1个RACH起始频域资源索引和同一个时刻可以频分复用的RACH资源个数(即连续的RACH频域资源个数),通过RACH频域资源配置可以确定RACH频域资源为一段连续的频 域资源。
每个小区广播1个起始的前导码根序列,基于配置的该起始前导码根序列通过循环移位可以得到本小区可用的前导码集合。
由于与传统NR所采用的蜂窝网络相比,NTN中终端设备与网络设备之间的信号传播时延大幅增加。此外,由于NTN中网络设备实现为卫星,且卫星的覆盖范围很大,对于同一个卫星覆盖范围内的不同终端设备,由于其所处的位置不同,他们与卫星之间的信号传输时延也可能存在较大差异。
对于具备TA预补偿能力的终端设备,从其随机接入的流程来看,终端设备可以自己估算TA,并使用自己估算的TA发送前导码,由于该终端设备在发送前导码之前已经调整了自己的上行定时,因此对于具有定位能力的终端设备,网络设备实际上在接收前导码时并不能获知终端设备实际的TA值,这样在调度Msg3时,由于不清楚终端设备的TA值,为了避免终端设备错过UL grant,网络设备就必须使用系统支持的最大TA值,去调度Msg3的UL grant资源位置。另一方面,对于不具备TA预补偿能力的终端设备,由于Msg2会提供终端设备真实的TA值,因此可以按照真实的TA去调度Msg3传输。但是,相关技术中网络设备并不知道终端设备是否在Msg1传输时进行了TA预补偿,即并不知道终端设备是否具备TA预补偿能力,因此无法针对不同能力的终端设备进行区别调度。由此,本申请实施例提供了一种随机接入资源配置方法,可用于解决相关技术中的问题。
下面,将结合几个示例性实施例,对本申请技术方案进行介绍说明。
请参考图7,其示出了本申请一个实施例提供的随机接入资源配置方法的流程图,该方法可应用于图1至图3所示的网络架构中,该方法可以包括如下几个步骤:
步骤710,网络设备向终端设备发送第一配置信息。
第一配置信息包括为第一类终端设备配置的第一随机接入资源池,以及为第二类终端设备配置的第二随机接入资源池。
其中,随机接入资源池中包括可用的随机接入资源。本申请实施例中,在网络设备与终端设备建立通信连接之前,网络设备需要先向终端设备分配可用的随机接入资源,以确保终端设备采用该随机接入资源可以向网络设备发送随机接入请求。可选地,随机接入资源可以是前导码,以及时频资源等,终端设备在网络设备分配的随机接入信道上向网络设备发送随机接入请求。
由于不同的终端设备在时频上是正交多址接入,即网络设备下同一个服务小区内不同终端设备的上行传输之间互不干扰,为了确保上行传输的正交性,避免小区内干扰,网络设备要求来自同一子帧但不同频域的终端设备的信号,到达网络设备的时间基本上是对齐的。在终端设备侧看来,TA(Timing Advance,定时提前)本质上是接收到下行子帧的起始时间与传输上行子帧的时间之间的一个负偏移(negative offset),网络设备通过适当地控制每个终端设备的偏移,可以控制来自不同终端设备的上行信号到达网络设备的时间,对于离网络设备较远的终端设备,因为有较大的传输延迟,就要比离网络设备较近的终端设备提前发送上行数据。可选地,TA预补偿能力是指终端设备可以对随机接入请求进行TA预补偿,即终端设备可以根据一定的TA值,提前发送随机接入请求,从而调整随机接入请求到达网络设备的时间。本申请实施例中,第一类终端设备是指具备TA预补偿能力的终端设备,第二类终端设备是指不具备TA预补偿能力的终端设备。
本申请实施例中,对于具备TA预补偿能力的终端设备,和不具备TA预补偿能力的终端设备,网络设备在调度上行资源时有不同的资源调度策略,因此,网络设备在接收到终端设备的随机接入请求时,需要对终端设备是否具备TA预补偿能力进行区分。由此,本申请实施例中,网络设备在给终端设备配置随机接入资源时,配置了两种不同的随机接入资源池,即第一随机接入资源池和第二随机接入资源池,且第一随机接入资源池和第二随机接入资源池不同,即第一随机接入资源池中的随机接入资源,不同于第二随机接入资源池中的随机接入资源。本申请实施例中,具备TA预补偿能力的第一类终端设备,可以采用第一随机接入资源池中的随机接入资源发送随机接入请求;不具备TA预补偿能力的第二类终端设备,可以采用第二随机接入资源池中的随机接入资源发送随机接入请求。网络设备接收到终端设备的随机接入请求后,即可根据该随机接入请求所采用的随机接入资源的不同,来区分终端设备是否具备TA预补偿能力,从而采用对应的资源调度策略对终端设备进行资源调度。
可选地,第一配置信息是指小区公共配置信息,即,网络设备可以通过广播的方式,在小区内向所有的终端设备广播第一配置信息。可选地,第一配置信息可以承载于系统消息中,例如,承载于SIBx(System Information Block x)中,其中,x为大于或等于1的正整数。本申请实施例通过这种方式,可以使得网络设备一次向其服务下的多个终端设备发送第一配置信息,避免网络设备多次发送第一配置信息,降低网络设备的处理开销。另外,本申请实施例中,第一配置信息可以承载在系统消息中,避免网络设备采用单独的信令来封装第一配置信息,减少了网络设备与终端设备间不必要的信令开销。此外,本申请实施例对第一配置信息的生成方式不作限定,可选地,第一配置信息可以是网络预配置的信息,也可以是协议中预先 规定的信息。
综上所述,本申请实施例提供的技术方案,通过网络设备向终端设备发送第一配置信息,第一配置信息包括为第一类终端设备配置的第一随机接入资源池,以及为第二类终端设备配置的第二类随机接入资源池,提供了一种随机接入资源的配置方法。并且,本申请实施例提供的技术方案,第一类终端设备是指具备TA预补偿能力的终端设备,第二类终端设备是指不具备TA预补偿能力的终端设备,由于网络设备针对终端设备是否具备TA预补偿能力,提供了不同的资源调度策略,通过给不同能力的终端设备配置不同的随机接入资源,可以使得网络设备在接收到终端设备的随机接入请求后,根据该随机接入请求使用的随机接入资源的不同,区分终端设备是否具备TA预补偿能力,从而采用相应的资源调度策略,有针对性地对终端设备进行资源调度,提升了网络设备进行资源调度的准确性与针对性,也提升了随机接入资源的利用率。
另外,本申请实施例提供的技术方案中,第一配置信息是指小区公共配置信息,可以避免网络设备需要多次向终端设备下发配置信息,降低了网络设备的处理开销。此外,第一配置信息可以承载在系统消息中,避免网络设备采用单独的信令来封装第一配置信息,减少了网络设备与终端设备之间不必要的信令开销。此外,第一配置信息可以是网络预配置的信息,也可以是协议中预先规定的信息,提升了第一配置信息生成的灵活性。
在一种可能的实施方式中,第一随机接入资源池包括第一时频资源,第二随机接入资源池包括第二时频资源;第一时频资源和第二时频资源没有重叠区域。由于终端设备向网络设备发送随机接入请求时需要占用一定的时频资源,本申请实施例中,可以给第一类终端设备和第二类终端设备配置不同的时频资源,即配置没有重叠区域的第一时频资源和第二时频资源,其中,第一类终端设备可以采用第一时频资源发送随机接入请求,第二类终端设备可以采用第二时频资源发送随机接入请求,网络设备接收到随机接入请求后,可以根据时频资源的不同,区分终端设备的类别。可选地,时频资源包括时域资源和频域资源,可以进一步根据时域资源的不同,和/或,频域资源的不同,来区分不同的时频资源。本申请实施例对时频资源的具体表现形式不作限定,可选地,时频资源可以分布图的形式表示,也可以表格的形式表示,在下述示例性实施例中,仅以分布图这一表现形式为例进行举例说明。
在一个示例中,第一时频资源包括第一时域资源,第二时频资源包括第二时域资源;第一时域资源和第二时域资源在时域上没有重叠区域,即,第一时域资源在时域上占用的时域单元,不同于第二时域资源在时域上占用的时域单元。可选地,时域单元可以是子帧,时隙等,本申请实施例对此不作限定。可选地,第一时频资源中包括的频域资源,可以与第二时频资源中包括的频域资源不相同,也可以与第二时频资源中包括的频域资源相同,本申请实施例对此不作限定。其中,第一时频资源中包括的频域资源与第二时频资源中包括的频域资源不相同,包括第一时频资源中包括的频域资源与第二时频资源中包括的频域资源部分不重叠,或者完全不重叠,本申请实施例对此不作限定。例如,如图8所示,其示出了一种时频资源分布图,该时频资源分布图的横坐标代表时域,纵坐标代表频域,图8示出了第一时频资源中的频域资源与第二时频资源中的频域资源相同,第一时频资源中的时域资源与第二时频资源中的时域资源不相同的情况,具体来说,第一时频资源中的时域资源与第二时频资源中的时域资源没有重叠区域,即第一时域资源与第二时域资源不重叠。
在另一个示例中,第一时频资源包括第一频域资源,第二时频资源包括第二频域资源;第一频域资源和第二频域资源在频域上没有重叠区域,即,第一频域资源在频域上占用的频域单元,不同于第二频域资源在频域上占用的频域单元。可选地,频域单元可以是载波、子载波等,本申请实施例对此不作限定。可选地,第一时频资源中包括的时域资源,可以与第二时频资源中包括的时域资源不相同,也可以与第二时频资源中包括的时域资源相同,本申请实施例对此不作限定。其中,第一时频资源中包括的时域资源与第二时频资源中包括的时域资源不相同,包括第一时频资源中包括的时域资源与第二时频资源中包括的时域资源部分不重叠,或者完全不重叠,本申请实施例对此不作限定。例如,如图9所示,其示出了一种时频资源分布图,该时频资源分布图的横坐标代表时域,纵坐标代表频域,图9示出了第一时频资源中的时域资源与第二时频资源中的时域资源相同,第一时频资源中的频域资源与第二时频资源中的频域资源不相同的情况,具体来说,第一时频资源中的频域资源与第二时频资源中的频域资源没有重叠区域,即第一频域资源与第二频域资源不重叠。
在又一个示例中,第一时频资源包括第一时域资源和第一频域资源,第二时频资源包括第二时域资源和第二频域资源;第一时域资源和第二时域资源在时域上没有重叠区域,和/或,第一频域资源和第二频域资源在频域上没有重叠区域,即,第一时频资源和第二时频资源,在时域上占用的子帧不相同,和/或,在频域上占用的带宽不相同。例如,如图10所示,其示出了一种时频资源分布图,该时频资源分布图的横坐标代表时域,纵坐标代表频域,图10示出了第一时频资源的时域资源与第二时频资源中的时域资源,在时域上没有重叠区域,且第一时频资源中的频域资源与第二时频资源中的频域资源,在频域上有重叠区 域的情况。
可选地,为了使得网络设备有足够的时间对终端设备的随机接入请求进行处理,第二时域资源中任意相邻随机接入信道机会RO的时间间隔,大于或等于网络设备的随机接入信道RACH接收窗的长度。可选地,第一时域资源中RO的时域分布密度,大于第二时域资源中RO的时域分布密度。
综上所述,本申请实施例提供的技术方案,通过网络设备给第一类终端设备配置第一时频资源,给第二类终端设备配置第二时频资源,且第一时频资源和第二时频资源没有重叠区域,从而提供了一种具体的随机接入资源配置方法。并且,本申请实施例提供了多种时频资源的配置方案,提升了网络设备对时频资源配置的灵活性。
在另一种可能的实施方式中,第一随机接入资源池包括第一前导码集合,第二随机接入资源池包括第二前导码集合;第一前导码集合和第二前导码集合中不存在相同的前导码。本申请实施例中,终端设备向网络设备发送随机接入请求,包括终端设备向网络设备发送随机接入前导码(preamble),网络设备接收到终端设备的前导码即可认为接收到终端设备的随机接入请求,然后向终端设备发送随机接入响应(Random Access Response,RAR),以通知终端设备随机接入请求成功接收。本申请实施例中,可以给第一类终端设备和第二类终端设备配置不同的前导码,即不存在相同前导码的第一前导码集合和第二前导码集合,其中,第一类终端设备可以根据第一前导码集合中前导码发送随机接入请求,第二类终端设备可以根据第二前导码集合中的前导码发送随机接入请求,网络设备接收到随机接入请求后,即可根据前导码的不同,区分终端设备的类别。本申请实施例对前导码集合的表现形式不作限定,可选地,前导码集合可以前导码索引列表的形式表示。
综上所述,本申请实施例提供的技术方案,通过网络设备给第一类终端设备配置第一前导码集合,给第二类终端设备配置第二前导码集合,且第一前导码集合和第二前导码集合中不存在相同的前导码,从而提供了一种具体的随机接入资源配置方法。并且,本申请实施例提供的技术方案,对于第一类终端设备和第二类终端设备采用前导码来区分,避免了使用时频资源来区分终端设备是否具备TA预补偿能力时,对时频资源进行分块可能带来的资源利用率较低的问题,提升了时频资源的利用效率。
在再一种可能的实施方式中,如图11所示,上述随机接入资源配置方法还可以包括如下几个步骤:
步骤720,终端设备采用第一随机接入资源池,向网络设备发送第一随机接入请求。
本申请实施例中,在终端设备属于第一类终端设备的情况下,终端设备采用第一随机接入资源池中的随机接入资源,向网络设备发送第一随机接入请求,从而网络设备在接收到终端设备的随机接入请求后,解析出该随机接入请求所使用的随机接入资源属于第一随机接入资源池,即可确定该终端设备为第一类终端设备,即该终端设备具备TA预补偿能力。
在一个示例中,上述随机接入资源配置方法还可以包括:终端设备确定TA预补偿值。其中,TA预补偿值用于在发送第一随机接入请求时进行TA预补偿。本示例中,在终端设备属于第一类终端设备,即终端设备具备TA预补偿能力的情况下,终端设备可以确定TA预补偿值,并且在发送第一随机接入请求时,使用该TA预补偿值进行TA预补偿。
可选地,在终端设备具备定位能力的情况下,TA预补偿值为终端设备根据定位能力确定的估计TA值。本示例中,在终端设备具备定位能力的情况下,终端设备可以根据自身的定位能力,估计自身与网络设备之间的距离,进一步计算出估计TA值,且将该估计TA值确定为TA预补偿值,并且在发送第一随机接入请求时使用该TA预补偿值,进行TA预补偿。
可选地,在终端设备不具备定位能力的情况下,TA预补偿值为公共TA值。本示例中,网络设备可以向其服务下的终端设备广播系统消息,公共TA值即可承载在该系统消息中。在终端设备不具备定位能力的情况下,终端设备可以将公共TA值确定为TA预补偿值,以在发送第一随机接入请求时使用该TA预补偿值,进行TA预补偿。需要说明的一点是,在终端设备具备定位能力的情况下,终端设备也可以将公共TA值确定为TA预补偿值,即终端设备不执行根据定位能力确定估计TA值的过程,本申请实施例对此不作限定。
步骤730,网络设备向终端设备发送第一随机接入响应。
网络设备接收到终端设备的随机接入请求后,即可根据该随机接入请求使用的随机接入资源,确定终端设备是否具备TA预补偿能力,即终端设备是否属于第一类终端设备,在确定终端设备属于第一类终端设备的情况下,向终端设备发送第一随机接入响应,该第一随机接入响应包括为第一类终端设备配置的相对TA值。
步骤740,终端设备根据TA预补偿值和相对TA值,确定实际TA值。
本申请实施例中,网络设备在第一随机接入响应中携带的相对TA值,是针对有TA预补偿能力的终端设备进行了TA预补偿后,终端设备与网络设备之间的偏移确定的,因此,具备TA预补偿能力的终端 设备在确定实际TA值时,需要考虑其在进行TA预补偿时确定的TA预补偿值。可选地,终端设备可以将TA预补偿值与相对TA值之和,确定为实际TA值,并使用该实际TA值,后续向网络设备传输上行信息。
综上所述,本申请实施例提供的技术方案,通过终端设备采用第一随机接入资源池,向网络设备发送第一随机接入请求,网络设备接收到随机接入请求后,确定终端设备具备TA预补偿能力的情况下,向终端设备发送第一随机接入响应,并且在该随机接入响应中携带相对TA值,终端设备根据相对TA值和进行TA预补偿时使用的TA预补偿值,确定实际TA值,从而确定了一种实际TA值的确定方法。并且,本申请实施例提供的技术方案中,针对具备TA预补偿能力的终端设备是否具备定位能力,提供了两种确定TA预补偿值的方法,在终端设备具备定位能力时,TA预补偿值可以是终端设备根据定位能力估计出的估计TA值,在终端设备不具备定位能力时,TA预补偿值可以是终端设备接收到公共TA值。通过给不同能力的终端设备设置的TA预补偿方式,提升了终端设备进行TA预补偿的灵活性。
在又一种可能的实施方式中,如图12所示,上述随机接入资源配置方法还可以包括如下几个步骤:
步骤7A0,终端设备采用第二随机接入资源池,向网络设备发送第二随机接入请求。
本申请实施例中,在终端设备属于第二类终端设备的情况下,终端设备采用第二随机接入资源池中的随机接入资源,向网络设备发送第二随机接入请求,从而网络设备在接收到终端设备的随机接入请求后,解析出该随机接入请求所使用的随机接入资源属于第二随机接入资源池,即可确定该终端设备为第二类终端设备,即该终端设备不具备TA预补偿能力。
步骤7B0,网络设备向终端设备发送第二随机接入响应。
网络设备在确定终端设备属于第二类终端设备的情况下,即可向终端设备发送第二随机接入响应,该第二随机接入响应包括为第二类终端设备配置的相对TA值。
步骤7C0,终端设备根据公共TA值和相对TA值,确定实际TA值。
本申请实施例中,由于网络设备可以向其服务下的终端设备广播系统消息,且该系统消息中携带有公共TA值,不具备TA预补偿能力的第二类终端设备也可以接收到该公共TA值,因此,网络设备向第二类终端设备发送随机接入响应以指示实际TA值时,可以将该公共TA值去除,向终端设备发送相对TA值,从而可以在一定程度上,减少随机接入响应中TA值的取值范围,从而有利于降低信令开销。终端设备接收到随机接入响应中的相对TA值之后,可以根据公共TA值和相对TA值,确定实际TA值。可选地,终端设备可以将公共TA值与相对TA值之和,确定为实际TA值,并使用该实际TA值,后续向网络设备传输上行信息。
综上所述,本申请实施例提供的技术方案,通过终端设备采用第二随机接入资源池,向网络设备发送第二随机接入请求,网络设备接收到随机接入请求后,确定终端设备不具备TA预补偿能力的情况下,向终端设备发送第二随机接入响应,并且在该随机接入响应中携带相对TA值,终端设备根据相对TA值和公共TA值,确定实际TA值,从而确定了一种实际TA值的确定方法。并且,相比于相关技术在随机接入响应中直接携带实际TA值,本申请实施例将实际TA值拆分为两部分发送给不具备TA预补偿能力的终端设备,一部分是通过在系统消息中承载公共TA值,另一部分是通过在随机接入响应中承载相对TA值,终端设备接收到随机接入响应后,根据公共TA值和相对TA值,即可确定实际TA值,从而减少了随机接入响应中TA值的取值范围,有利于降低信令开销。
需要说明的是,在上述方法实施例中,主要从网络设备和终端设备之间交互的角度,对本申请技术方案进行了介绍说明。上述有关终端设备执行的步骤,可以单独实现成为终端设备侧的随机接入资源配置方法;上述有关网络设备执行的步骤,可以单独实现成为网络设备侧的随机接入资源配置方法。
