Description
技术领域
本发明有关无线多信元通信系统。更特别是,本发明是有关通过使用方向性波束及全向波型测量被接收自信元的信号选择及再选择信元的方法及装置。
背景技术
与无线通信相关的最重要议题之一是如何改良促进通信的无线多信元通信系统容量。被开发的一新领域是使用方向性波束天线来改良基地台及无线传送/接收单元(WTRUs)间的正向及反向链路的链路边际。方向性天线对传统全向天线的增加增益是增加无线传送/接收单元及基地台处的被接收信号增益。
当无线传送/接收单元被赋予电源时,无线传送/接收单元是执行起始信元搜寻程序,其期间无线传送/接收单元测量被接收自多个信元的多个信号并选择具有最强信号位准的信元之一。例如,码分多路访问(CDMA)系统中,无线传送/接收单元是获得来自信元的前导信号并接着同步化该信元。为了获得前导信号,无线传送/接收单元搜寻所有已知前导编码的可能性,并选择具有最强前导信号的信元。信元被选择之后且当无线传送/接收单元从一位置移动至另一位置时,无线传送/接收单元可找到一个登录的较佳信元(也就是具有较佳品质测量的信元)。再评价该被选择信元的程序是被称为信元再选择或闲置交递。
切换波束系统是为若干固定方向性波束被定义且收发器选择提供最佳信号品质及最少干扰的方向性波束的系统。无线传送/接收单元处的方向性天线使用须对各方向性波束测量信号位准来选择天线的最佳方向性模式。无线传送/接收单元必须继续监视各方向性模式中的被接收信号位准,并定期再选择最佳方向性模式来适应环境改变及无线传送/接收单元的移动。被接收于无线传送/接收单元的信号位准是因多路传送而经常改变。
起始信元选择及信元再选择程序中,无线传送/接收单元可利用被切换波束系统。为被装设被切换波束天线的无线传送/接收单元设计信元选择及信元再选择程序时,执行选择及再选择程序所花费时间及该被选择或被再选择信元/波束效能之间具有置换关系。
发明内容
本发明有关选择及再选择基于使用多个方向性波束及/或全向波型完成测量无线通信系统中的信元的方法及装置。该系统包含多个信元及至少一无线传送/接收单元。各信元是被至少一基地台服务。无线传送/接收单元包含于多个方向性波束及全向波型间产生及切换一波束的切换波束(也就是智能)天线。
依据本发明第一实施例,无线传送/接收单元是使用全向波型测量被接收自多个信元的信号。无线传送/接收单元是基于使用全向波型完成测量被接收自多个信元的信号结果来选择具有最强信号的信元。无线传送/接收单元登录该被选择信元并接着使用各多个方向性波束测量被接收自该被选择信元的信号。无线传送/接收单元是基于使用方向性波束测量被接收自该被选择信元的信号结果来选择具有最强信号的方向性波束作为与该被选择信元通信的主动波束。
依据本发明第二实施例,无线传送/接收单元是使用多个方向性波束或全向波型测量被接收自多个信元的信号。无线传送/接收单元是基于使用多个方向性波束或全向波型测量被接收自多个信元的信号结果来选择具有最强信号的信元/波束组合。无线传送/接收单元是使用该被选择波束作为通常被用来与被选择信元通信的主动波束来登录该被选择信元。
依据本发明第三实施例,无线传送/接收单元是使用全向波型测量被接收自多个信元的信号。无线传送/接收单元是基于使用全向波型完成测量被接收自多个信元的信号结果来选择具有一信元子组。无线传送/接收单元接着使用各多个方向性波束测量被接收自各该信元的信号。无线传送/接收单元是基于使用各多个方向性波束测量被接收自该子组中的各信元的信号结果来选择具有最强信号的信元/波束组合。无线传送/接收单元是使用该被选择波束作为通常被用来与被选择信元通信的主动波束来登录该被选择信元。
依据本发明第四实施例,无线传送/接收单元是使用通常被用来与被选择信元通信的主动波束来登录该被选择信元及测量被接收自多个邻接信元的信号。无线传送/接收单元是基于使用该主动波束测量被接收自该多个邻接信元的信号结果来选择该邻接信元的子组。无线传送/接收单元是使用多个方向性波束或全向波型测量被接收自邻接信元的信号。若无线传送/接收单元决定被接收自该子组中的邻接信元的信号最强测量结果是高于被接收自该被选择信元的信号最佳测量结果,则无线传送/接收单元激活从被选择信元至具有最强测量结果的子组中的邻接信元的信元交递。
依据本发明第五实施例,无线传送/接收单元是使用通常被用来与被选择信元通信的主动波束来登录该被选择信元及测量被接收自多个邻接信元的信号。无线传送/接收单元是基于使用该主动波束测量被接收自该多个邻接信元的信号结果来选择该邻接信元的第一子组。无线传送/接收单元是使用全向波型测量被接收自该第一子组中的邻接信元的信号。无线传送/接收单元是基于测量被接收自该第一子组中的多个邻接信元的信号结果来选择该邻接信元的第一子组的第二子组。无线传送/接收单元是使用各多个方向性波束测量被接收自该第二子组中的邻接信元的信号。若无线传送/接收单元决定被接收自第二子组中的邻接信元的信号最强测量结果是高于被接收自该被选择信元的信号最佳测量结果,则无线传送/接收单元激活从被选择信元至具有最强测量结果的第二子组中的邻接信元的信元交递。
依据本发明第六实施例,无线传送/接收单元是使用通常全向波型来登录该被选择信元及测量被接收自多个邻接信元的信号。无线传送/接收单元是基于使用该全向波型测量被接收自该多个邻接信元的信号结果来选择该邻接信元的子组。无线传送/接收单元是使用多个方向性波束测量被接收自该子组中的各邻接信元的信号。若无线传送/接收单元决定被接收自该子组中的邻接信元的信号最强测量结果是高于被接收自该被选择信元的信号最佳测量结果,则无线传送/接收单元激活从被选择信元至具有最强测量结果的子组中的邻接信元的信元交递。

具体实施方式
此后,″无线传输/接收单元″名词是包括但不受限于用户设备(UE),移动站,固定或移动用户单元,呼叫器或任何可操作于无线环境中的其它类型装置。这些项在此可被交递使用。此后当被称为″基地台″名词者,是包括但不受限于B节点,地址控制器,访问点(AP)或无线环境中的任何其它类型接介装置。
本发明特性可被并入集成电路(IC)或被配置于包含多个互连组件的电路中。
图1显示依据本发明操作的无线通信系统100。无线通信系统100包含多个基地台104及多个无线传输/接收单元102。各基地台104是服务多个信元106至少之一。各无线传输/接收单元102是被登录至少一信元106,并包含被用来产生多个方向性波束或全向波型的一切换波束天线108。无线传输/接收单元102是于多个方向性波束或全向波型间切换波束以便与信元106的基地台104通信。
当无线传输/接收单元102被打开时,起始信元搜寻程序被激活。起始信元搜寻程序期间,无线传输/接收单元102接收来自无线传输/接收单元102附近的多个信元106的信号,并依据预定准则选择一信元106。使用切换波束天线108的起始信元搜寻程序期间,无线传输/接收单元102是使用全向波型或方向性波束。一旦被与信元106登录的无线传输/接收单元102被选择,则无线传输/接收单元102定期监视来自邻接信元的信号,并经由信元再选择程序执行信元交递。
图2是依据本发明第一实施例包含使用无线传送/接收单元102的切换波束天线108选择信元106的方法步骤处理200流程图。当无线传送/接收单元102被开启时,无线传送/接收单元102是进入预设模式,借此全向波型是从无线传送/接收单元102的切换波束天线108被发射出。步骤202中,无线传送/接收单元102是使用全向波型来测量被接收自多个信元106的信号。步骤204中,无线传送/接收单元是基于被执行于步骤202的测量结果来选择具有最强信号的信元106。步骤206中,无线传送/接收单元登录该被选择信元106(步骤206)。第一实施例的优点是该信元选择程序可被快速执行。
一旦无线传送/接收单元102被登录该被选择信元106,则波束选择程序被执行。最佳波束是通过评估所有被定义波束(或可替代为被定义波束子组),及决定被无线传送/接收单元102的切换波束天线108用来传送及接收的最佳波束来选择。波束选择程序可于步骤204的信元选择之后或无线传送/接收单元102被指派至该被选择信元106所提供与该被选择信元106的基地台104通信的专用频道的登录步骤206之后被执行。任一例中,当切换被发射自天线108的波束为各多个方向性波束时,无线传送/接收单元102是测量被接收自该被选择信元106的信号(步骤208)。无线传送/接收单元102接着基于被执行于步骤208中的测量结果来选择具有最强信号的方向性波束作为与该被选择信元106通信的主动波束(步骤210)。无线传送/接收单元102维持与该被选择信元106的登录直到另一信元106经由信元选择程序被选择为止,当参考图5至图7时其将被详细解释。
图3是依据本发明第二实施例包含使用无线传送/接收单元102的切换波束天线108选择信元106的方法步骤处理300流程图。当无线传送/接收单元102被开启时,无线传送/接收单元102是通过将被发射自天线108的波束切换为各多个方向性波束或全向波型来测量被接收自多个信元106的信号(步骤302)。此实施例中,无线传送/接收单元102不仅选择信元106来登录,还选择波束当作与该被选择信元通信的主动波束。步骤304中,无线传送/接收单元是基于被执行于步骤302的测量结果来选择具有最强信号的信元/波束组合。步骤306中,无线传送/接收单元是使用该被选择波束作为通常被用来与该被选择信元通信的主动波束来登录该被选择信元106。无线传送/接收单元102维持与目前信元106的登录直到另一信元106经由信元选择程序被选择为止。
处理300中,使用全向波型来执行起始信元搜寻程序的优先性可被指定,借此若被选择波束非全向波型,则标示最佳方向性波束/信元组合的测量结果是被与标示最佳全向波型/信元组合的测量结果做比较。因此,方向性波束仅若与方向性波束相关的测量结果超过与全向波型相关的测量结果有一预定门槛才被选择。否则,全向波型是被选择。该门槛可被设定为零,该例中全向波型并不具有优先性。
图4是依据本发明第三实施例包含使用无线传送/接收单元102的切换波束天线108选择信元的方法步骤处理400流程图。当无线传送/接收单元102被开启时,无线传送/接收单元102是使用发射自无线传送/接收单元102的切换波束天线108的全向波型来测量被接收自多个信元106的信号(步骤402)。无线传送/接收单元102接着基于被执行于步骤402的测量结果来选择信元的子组(步骤404)。选择信元子组时,无线传送/接收单元102可基于使用全向波型的测量结果,具有预定门槛以上的测量结果的信元,或使用某些其它准则来降低不需被测量的信元数来选择最佳信元。此降低信元选择或再选择程序中的时间花费。
无线传送/接收单元102是使用被发射自无线传送/接收单元102的切换波束天线108的多个方向性波束来测量子组中各信元的信号(步骤406)。无线传送/接收单元102基于被执行于步骤406的测量结果来选择具有最强信号的信元/波束组合(步骤408)。无线传送/接收单元102是使用该被选择波束作为与该被选择信元通信的主动波束来登录该被选择信元106(步骤410)。无线传送/接收单元102维持与目前信元106的登录直到另一信元106经由信元选择程序被选择为止。
处理400中,使用全向波型来执行起始信元搜寻程序的优先性可被指定,借此若被选择波束非全向波型,则标示最佳方向性波束/信元组合的测量结果是被与标示最佳全向波型/信元组合的测量结果做比较。因此,方向性波束仅若与方向性波束相关的测量结果超过与全向波型相关的测量结果有一预定门槛才被选择。否则,全向波型是被选择。该门槛可被设定为零,该例中全向波型并不具有优先性。
图5是依据本发明第四实施例包含使用无线传送/接收单元102的切换波束天线108再选择信元106的方法步骤处理500流程图。起始信元搜寻程序被完成且无线传送/接收单元102被登录该被选择信元106之后,无线传送/接收单元102定期或不定期使用被用来与该被选择信元106通信的主动波束来测量被接收自多个邻接信元的信号(步骤502)。无线传送/接收单元102基于被执行于步骤502的测量结果来选择邻接信元的子组(步骤504)。选择邻接信元子组时,无线传送/接收单元102可基于例如其测量结果,具有预定门槛以上的测量结果的信元,或具有超过被选择信元测量有一预定门槛的测量结果的信元来选择最佳信元。可选择是,信元子组可包含所有被测量信元。
无线传送/接收单元102是使用被发射自无线传送/接收单元102的切换波束天线108的多个方向性波束或全向波型来测量被接收自子组中的各邻接信元的信号(步骤506)。无线传送/接收单元102接着决定被接收自子组中的邻接信元的信号最强测量结果是否较被接收自该被选择信元106的信号最佳测量结果为高(可被设定为零的某些门槛)(步骤508)。若步骤508的决定为负,则无线传送/接收单元102是维持与该被选择信元106的登录且处理500结束。若步骤508的决定为正,则无线传送/接收单元102激活从该被选择信元至具有最强测量结果的子组中的邻接信元的信元交递(也就是执行信元再选择处理)(步骤510)。
图6是依据本发明第五实施例包含使用无线传送/接收单元102的切换波束天线108再选择信元106的方法步骤处理600流程图。起始信元搜寻程序被完成且无线传送/接收单元102被登录该被选择信元106之后,无线传送/接收单元102定期或不定期使用被用来与该被选择信元106通信的主动波束来测量被接收自多个邻接信元的信号(步骤602)。无线传送/接收单元102基于被执行于步骤602的测量结果来选择邻接信元的第一子组(步骤604)。选择邻接信元的第一子组时,无线传送/接收单元102可基于例如使用其测量结果,具有预定门槛以上的测量结果的信元,或具有超过被选择信元测量有一预定门槛的测量结果的信元来选择最佳信元。可选择是,信元子组可包含所有被测量信元。
无线传送/接收单元102是使用被发射自无线传送/接收单元102的切换波束天线108的全向波型来测量被接收自第一子组中的邻接信元的信号(步骤606)。无线传送/接收单元102接着基于被执行于步骤606的测量结果来选择邻接信元的第一子组的第二子组(步骤608)。选择邻接信元的第二子组时,无线传送/接收单元102可基于例如其测量结果,具有预定门槛以上的测量结果的信元,或具有超过被选择信元测量有一预定门槛的测量结果的信元来选择最佳信元。可选择是,该子组可包含所有属于第一子组的信元。
无线传送/接收单元102是使用被发射自无线传送/接收单元102的切换波束天线108的各多个方向性波束来测量被接收自第二子组中的邻接信元的信号(步骤610)。无线传送/接收单元102接着决定被接收自第二子组中的邻接信元的信号最强测量结果是否较被接收自该被选择信元106的信号最佳测量结果为高(可被设定为零的某些门槛)(步骤612)。若步骤612的决定为负,则无线传送/接收单元102是维持与该被选择信元106的登录且处理600结束。若步骤612的决定为正,则无线传送/接收单元102激活从该被选择信元至具有最强测量结果的第二子组中的邻接信元的信元交递(也就是执行信元再选择处理)(步骤614)。
图7是依据本发明第六实施例包含使用无线传送/接收单元102的切换波束天线108再选择信元106的方法步骤处理700流程图。起始信元搜寻程序被完成且无线传送/接收单元102被登录该被选择信元106之后,无线传送/接收单元102定期或不定期使用被发射自无线传送/接收单元102的切换波束天线108的全向波型来测量被接收自多个邻接信元的信号(步骤702)。无线传送/接收单元102基于被执行于步骤702的测量结果来选择邻接信元的子组(步骤704)。选择邻接信元的子组时,无线传送/接收单元102可基于例如使用其测量结果,具有预定门槛以上的测量结果的信元,或具有超过被选择信元测量有一预定门槛的测量结果的信元来选择最佳信元。可选择是,信元的第一子组可包含所有被测量信元。
无线传送/接收单元102是使用被发射自无线传送/接收单元102的切换波束天线108的各多个方向性波束来测量被接收自子组中的各邻接信元的信号(步骤706)。无线传送/接收单元102接着决定被接收自子组中的邻接信元的信号最强测量结果是否较被接收自该被选择信元106的信号最佳测量结果为高(可被设定为零的某些门槛)(步骤708)。若步骤708的决定为负,则无线传送/接收单元102是维持与该被选择信元的登录且处理700结束。若步骤708的决定为正,则无线传送/接收单元102激活从该被选择信元至具有最强测量结果的子组中的邻接信元的信元交递(也就是执行信元再选择处理)(步骤710)。
