此外,当前的RRM测量机制中,用户设备对测量结果的上报触发判断也没有考虑到上述的小区动态特性,从而在用户设备侧可能会例如漏报一些适合作为候选小区的邻小区,因此基站基于用户设备的测量报告结果所进行的例如切换等资源管理决策可能是不合理的。

<第一实施例>
图1示出了根据本申请的一个实施例的用于无线通信的用户设备侧的装置100的结构框图,装置100包括:信息获取单元101,被配置为获取用户设备的服务小区以及/或者相邻小区的用于无线资源管理的小区专用动态偏移信息,其中,小区专用动态偏移与相应小区的传输能力有关,传输能力包括小区多天线传输性能增益、负载情况中至少之一;测量单元102,被配置为测量服务小区和相邻小区的参考信号;以及小区重选/测量报告单元103,被配置为根据用户设备的连接状态,基于小区专用动态偏移以及对服务小区和相邻小区的测量结果进行小区重选或测量报告。在现有的LTE***中,由于用户设备用于小区切换等无线资源管理操作的测量上报值仅针对单个天线端口所对应的信道,小区基站的多天线传输性能增益被忽略,因此可能造成例如用户设备没有接入由于多天线传输性能增益较大而实际性能较好的小区而接入了由于多天线传输性能增益较小而实际性能较差的小区的情形。
在装置100中,信息获取单元101获取用户设备的服务小区以及/或者相邻小区的用于无线资源管理的小区专用动态偏移信息,并且小区重选/测量报告单元103在进行小区重选或测量报告时利用小区专用动态偏移的信息,从而能够更为准确地确定实际性能较好的小区。其中,小区专用动态偏移是特定于小区的而可能动态变化的,不同的小区通常具有不同的动态偏移值。
具体地,信息获取单元101可以获取服务小区(本小区)和相邻小区两者的小区专用动态偏移信息,也可以仅获取二者之一。例如,在用于小
区切换的测量报告事件配置中,可以仅获取相邻小区的小区专用动态偏移,这是因为本基站自然知悉本小区的具体情况而在进行无线资源管理决策时予以考虑;在进行小区重选时,信息获取单元101可以例如仅获取本小区的小区专用动态偏移,例如小区重选/测量报告单元103可以将本小区的测量结果与小区专用动态偏移相加并且与其他小区的测量结果相比较以确定要接入的小区,这样可以避免频繁的小区重选。
小区重选/测量报告单元103根据用户设备的连接状态比如是否处于无线资源控制(RRC)已连接的状态,来基于小区专用动态偏移和测量单元102的测量结果来进行小区重选或测量报告。例如,在处于RRC已连接的状态时,进行测量报告,而处于RRC未连接(idle)的状态时,进行小区重选。
在一个示例中,测量单元102的测量结果包括与参考信号接收功率(RSRP)和参考信号接收质量(RSRQ)中的至少一个相关的测量值。
例如,小区重选/测量报告单元103可以被配置为基于小区专用动态偏移信息和上述测量结果来对所测量的小区进行排序,并且基于排序结果确定要接入的小区。作为示例,小区重选/测量报告单元103可以结合每一个小区的小区专用动态偏移信息和测量结果来获得该小区的传输性能,并且将传输性能最好的小区确定为要接入的小区。或者,小区重选/测量报告单元103可以将传输性能最好且信令传输能够得到保证的小区确定为要接入的小区,此示例适用于有些信令例如PDCCH信令等控制信令不会经过多天线处理从而不能享受多天线增益的情形,因此需要要求用户设备对信令的接收质量达到一定程度,例如,可以要求测量结果本身达到一定阈值。
例如,在进行小区重选时,用户设备可以基于所获取的小区专用动态偏移信息和测量结果来对测量的小区排序,并且选择传输性能最好的小区来接入。可以理解,在本发明的小区重选思想的基础上可以进一步结合现有的小区重选规则,本发明并不意图进行限制。
在一个具体的示例中,用户设备对服务小区以及相邻小区的参考信号进行测量并且分别得到以RSRP计量的测量值Qmeas,s以及Qmeas,n,基于基站通知的包括小区专用动态偏移的小区重选参数根据下式进行小区排序:
Rs’=Qmeas,s+QHyst-Qoffsettemp+Qoffsetdyn,s (1)
Rn’=Qmeas,n-Qoffset-Qoffsettemp+Qoffsetdyn,n (2)
其中,Rs’代表服务小区用于参与小区排序的R参考值,Rn’代表相邻小区用于参与小区排序的R参考值,Qoffsetdyn,s代表服务小区的小区专用动态偏移,Qoffsetdyn,n代表邻小区的小区专用动态偏移,此外,如3GPP的技术标准TS36.331及TS25.331所规定的,QHyst代表排序准则的迟滞值,Qoffset基于服务小区与相应邻小区是同频还是异频分别代表OAM静态配置的两小区间的偏移或者频率专用偏移,Qoffsettemp代表各小区共用的临时偏移值。用户设备根据上述方式计算得到的R参考值,对满足S准则的所有小区进行排序,在一些示例中选择排在首位的最佳小区执行小区重选操作。
在另一个可选的示例中,用户设备首先根据现有标准中的R准则计算参考值Rs和Rn,例如根据下式计算:
Rs=Qmeas,s+QHyst-Qoffsettemp (3)
Rn=Qmeas,n-Qoffset–Qoffsettemp (4)
其中,式(3)和(4)中相同的符号代表与式(1)和(2)中相同的含义。之后,用户设备筛选出参考值Rn大于服务小区的Rs的多个候选邻小区,针对这多个候选邻小区再分别计算Rn’并进行小区排序,将其中Rn’值最大的邻小区作为重选对象从而重选到实际传输性能最佳的小区。在这个示例中,用户设备不需使用服务小区的小区专用动态偏移Qoffsetdyn,s,因而可以不设置该值而减小信令消耗。
本领域技术人员根据现有技术以及上述示例可以设计出其他的组合或变形方式,例如用户设备仅从基站接收Qoffsetdyn,s与Qoffsetdyn,n的差值作为相应邻小区的小区专用动态偏移,并且在计算Rn’时使用Qoffsetdyn,s与Qoffsetdyn,n的差值,而配合Rs来进行小区排序,本发明不在此一一例举。
其中,信息获取单元101可以通过***信息或用户设备中记录的历史信息来获取小区专用动态偏移信息。其中,***信息例如通过广播信道(例如BCCH)来获取,而历史信息例如为在该用户设备之前接入某一个小区时从其获得的该小区与邻小区的小区专用动态偏移信息。或者,历史信息可以为每一次该用户设备接入一个小区时所记录的该小区的小区专用动态偏移信息。信息获取单元101例如在用户设备处于RRC idle时将这些***信息或历史信息作为相邻小区的小区专用动态偏移信息以进行例如小区重选。
此外,信息获取单元101还可以通过从服务小区的基站接收RRC信
令来获取服务小区和相邻小区的小区专用动态偏移信息。例如,信息获取单元101在用户设备与服务小区建立RRC连接时获取相邻小区的ID和相应的动态偏移信息,例如,在RRC消息的信息单元SystemInformationBlockType4以及/或者SystemInformationBlockType5中获取各小区的动态偏移信息。而在RRC idle状态下使用之前记录的邻小区动态偏移信息和所获得的邻小区ID来确定当前测量的邻小区的动态偏移信息。
上文中的多天线传输性能增益例如可以包括小区预编码增益以及/或者波束赋型增益。此外,在一个示例中,小区专用动态偏移还与小区负载有关,其中,负载越大,偏移值越小。
<第二实施例>
下面将描述根据本申请的用于无线通信的用户设备侧的装置用于测量报告的示例。通常,基站通过高层信令对用户设备进行无线资源管理(RRM)测量配置,并且基于用户设备按照该配置反馈的对于邻小区和本小区的RRM测量结果作出无线资源管理决策,例如小区切换、双连接启动或调整、载波聚合启动或载波组合调整等。
在本实施例中,信息获取单元101被配置为在用户设备的无线资源控制(RRC)连接状态为已连接的情况下,获取来自用户设备的服务小区的测量配置信息,其中,测量配置信息例如包含动态偏移以及关于考虑了动态偏移的报告触发事件的测量报告配置。
注意,该报告触发事件是本申请新定义的考虑了动态偏移的因素的事件,在后文中将进行详细描述。换言之,信息获取单元101从服务小区(基站)获取包含考虑了动态偏移的报告触发事件的触发条件等的测量报告配置的信息以及相关的动态偏移的信息。例如,包含有小区专用动态偏移信息的上述测量配置信息可以包括在RRC信令中,具体可以包括在RRC信令的MeasObjectEUTRA(比如CellsToAddMod中)中,而有关测量报告配置的信息例如可以包括在measconfig IE中。
作为一个示例,小区重选/测量报告单元103可以包括:测量报告触发模块,被配置为至少基于小区专用动态偏移、测量结果以及测量报告配置来触发测量报告。例如,测量报告触发模块在某一个或多个小区的小区专用动态偏移和测量结果满足测量报告配置中定义的测量上报事件时,将
该小区的ID加入到测量报告中并触发测量报告,例如通过该测量报告向基站报告传输性能最好的相邻小区以被切换到该相邻小区。
作为另一个示例,小区重选/测量报告单元103可以包括:测量报告生成模块,被配置为将满足考虑了小区专用动态偏移的报告触发事件的相邻小区的测量结果包含于测量报告中。在这种情况下,用户设备侧不进行目标小区的判断,而是将测量结果上报给基站,例如由基站来选择目标小区以进行小区切换、双连接、载波聚合等管理操作。
<第三实施例>
下面将描述根据本申请的用于无线通信的用户设备侧的装置用于小区重选的示例。在该示例中,用户设备处于RRC idle的状态,信息获取单元101例如可以通过如上所述的***信息或者历史信息来获取小区专用动态偏移信息,小区重选/测量报告单元103例如可以基于该小区专用动态偏移信息和测量单元102的测量结果来确定传输性能最好的小区作为要接入的小区,例如通过第一实施例中的小区排序方式来进行确定。
此外,如图2所示,根据该实施例的装置200除了包括参照图1所述的装置100的部件之外,还可以包括:能力标记发送单元201,被配置为在完成小区重选之后,向小区重选的目标小区发送表示在确定时考虑了小区动态偏移的设备能力标记。这样,目标小区可以例如优先为该用户设备配置多天线传输方案。
例如,能力标记发送单元201可以被配置为在RRC信令中发送设备能力标记。又例如能力标记发送单元201可以被配置为在随机接入请求信令中发送设备能力标记。
上述装置100和200通过在进行小区重选或测量报告时将小区专用动态偏移信息考虑在内,可以准确地反映小区的实际性能从而有利于更准确的决策。
<第四实施例>
图3示出了根据本申请的一个实施例的用于无线通信的基站侧的装置300的结构框图,装置300包括:指示生成单元301,被配置为生成包含基站的服务小区以及/或者相邻小区的用于无线资源管理的小区专用动
态偏移的指示信息,以用于指示基站服务的用户设备,其中,小区专用动态偏移与相应小区的传输能力有关,传输能力包括小区多天线传输性能增益、负载情况中至少之一;以及无线资源管理单元302,被配置为基于小区专用动态偏移进行对用户设备的无线资源管理。
如上所述,多天线传输性能增益可以包括小区预编码增益以及/或者波束赋型增益。小区专用动态偏移还可以与小区负载有关,其中,负载越大,偏移值越小。其中,小区的多天线传输性能增益和小区负载根据相应小区的工作状态是动态变化的,例如部署有多天线的小区的多天线传输性能可能随当前服务的用户数量而变化。
在装置300中,指示生成单元301生成包含小区专用动态偏移的指示信息,并且无线资源管理单元302基于该动态偏移来进行无线资源管理比如小区切换、双连接、载波聚合等操作。
如图3中的虚线框所示,装置300还可以包括通信单元303,被配置为向基站服务的用户设备发送指示信息,以及接收来自用户设备的接入请求或测量报告。
在一个示例中,指示生成单元301将小区专用动态偏移包含于***信息中,并且通信单元303通过广播信道发送包含小区专用动态偏移的***信息。例如,***信息为SIB,可以在SystemInformationBlockType3中的cellReselectionInfoCommon内增加本小区动态偏移项(q-OffsetDyn),在SystemInformationBlockType4中的IntraFreqNeighCellInfo中增加同频邻小区的动态偏移项(q-OffsetDyn),在SystemInformationBlockType5中的InterFreqNeighCellInfo中增加异频邻小区的动态偏移项(q-OffsetDyn)。例如在用户设备处于RRC idle的情况下,可以通过接收该***信息来执行小区重选等操作。
在另一个示例中,例如在用户设备处于RRC已连接的状态下时,指示生成单元301将小区专用动态偏移包含于RRC信令中,并且通信单元303通过数据信道发送包含小区专用动态偏移的RRC信令。如前所述,动态偏移信息例如可以包括在RRC信令的MeasObjectEUTRA(比如CellsToAddMod中)中,此外,也可以包括在RRC的***信息块中,具体地,例如包含于上述的SystemInformationBlockType3、SystemInformationBlockType4、SystemInformationBlockType5中。
此外,指示生成单元301还可以将小区专用动态偏移以及关于考虑了
小区专用动态偏移的报告触发事件的测量报告配置包含于RRC信令的测量配置信息中,以用于用户设备的测量报告。即,所发送的RRC信令中还包括用于用户设备的测量报告配置。如前所述,测量报告配置的信息例如可以包括在measconfig IE中。此外,measconfig中还可以包括基站希望用户设备进行测量的小区的列表、各个测量报告事件的参数等。当用户设备按照测量配置的要求对各个小区完成了测量,基于事件参数确定测量结果是否满足相应的报告触发事件,如果满足则报告小区ID、满足的报告触发事件ID以及/或者具体测量结果等内容。
作为示例,无线资源管理单元302确定来自用户设备的测量报告中包含的相邻小区的测量结果,基于相邻小区的测量结果以及相应的小区专用动态偏移,确定用于用户设备的目标接入小区。在该示例中,由基站侧来进行目标接入小区的确定。此外,无线资源管理单元302可以基于该测量结果对应的报告触发事件,确定目标接入小区为用户设备的切换目标小区、双连接目标小区或载波聚合目标小区中至少之一。例如,可以设置考虑了小区专用动态偏移的针对切换、双连接、载波聚合的新的报告触发事件并为其分配唯一ID。
注意,这里所述的报告触发事件是本申请新定义的考虑了小区专用动态偏移的事件。例如,可以定义新的事件A7和A8,其中,A7包括两个进入条件:
Mn+Ofn+Ocn+Odn-Hys>Mp+Ofp+Ocp+Ods+Off (5)
Mn+Ofn+Ocn-Hys>第一阈值 (6)
其中,Mn为不考虑偏移的邻小区测量结果,Ofn为邻小区频率的频率专用偏移,Ocn为通过OAM赋值的静态邻小区专用偏移,Odn为本发明中引入的相邻小区的小区专用动态偏移,Hys为该事件的滞后参数,Mp为不考虑偏移的主小区的测量结果,Ofp为主频的频率专用偏移,Ocp为通过OAM赋值的静态主小区专用偏移,Ods为本发明中引入的服务小区的小区专用动态偏移,Off为针对该事件的偏移参数,而第一阈值例如可以在measconfig中设置。换言之,当小区满足事件A7的两个条件时,可以报告该小区的ID、A7的事件ID以及/或者测量结果。其中,条件(6)保证了邻小区的例如不经过多天线处理而无法享受多天线传输性能增益的传输的信号质量。
此外,在优选的示例中还基于本发明的思想设置A7事件的离开条件:
Mn+Ofn+Ocn+Odn-Hys<Mp+Ofp+Ocp+Ods+Off (7)
Mn+Ofn+Ocn-Hys<0 (8)借此,用户设备根据上述测量报告触发事件A7配置进行相应的测量结果上报,基站根据该事件下的测量报告确定是否进行主小区Pcell/PScell的切换及切换目标小区选择。
事件A8包括如下两个进入条件:
Mn+Ocn+Odn-Hys>Ms+Ocs+Ods+Off (9)
Mn+Ocn-Hys>第二阈值 (10)
此外,在优选的示例中还基于本发明的思想设置A8事件的离开条件:
Mn+Ocn+Odn-Hys<Ms+Ocs+Ods+Off (11)
Mn+Ocn-Hys<0 (12)
其中,相同的符号与式(5)和(6)中具有相同的含义,第二阈值例如也可以在measconfig中设置。类似地,用户设备根据上述测量报告触发事件A8配置进行相应的测量结果上报,例如可以报告该小区的ID、A8的事件ID以及/或者测量结果,而基站根据该事件下的测量报告确定是否进行辅小区Scell的添加、删除或者替换。
本领域技术人员根据现有技术以及上述示例可以设计出其他的组合或变形方式,例如用户设备仅从基站接收Qdn与Ods的差值作为相应邻小区的小区专用动态偏移,本发明不在此一一例举。
此外,在装置300工作为用户设备的目标接入基站的情况下,通信单元303还可以被配置为从用户设备接收表示该用户设备考虑了小区专用动态偏移的设备能力标记,在设备能力标记表明接入请求考虑了小区专用动态偏移的情况下,无线资源管理单元302被配置为优先为该用户设备确定多天线传输方案。
例如,在用户设备完成小区重选之后,向选中的小区的通信单元303发送上述设备能力标记,在随后的传输中,无线资源管理单元302优先为该用户设备确定多天线传输方案,这是因为该设备能力标记表明在选择该小区时考虑了其多天线传输性能增益。
根据该实施例的装置300实现了基于小区专用动态偏移的无线资源管理,提高了资源利用效率。
<第五实施例>
图4示出了根据本申请的一个实施例的用于无线通信的基站侧的装置400的结构框图,装置400包括:通信单元401,被配置为与相邻基站交互各自的服务小区的用于无线资源管理的小区专用动态偏移信息,其中,小区专用动态偏移与相应小区的传输能力有关,传输能力包括小区多天线增益、负载情况中至少之一;以及无线资源管理单元402,被配置为基于基站以及相邻基站的服务小区的小区专用动态偏移信息对基站的用户设备进行无线资源管理。
在该装置400中,通信单元401使得相邻基站之间能够交互各自服务小区的动态偏移信息,从而使得基站可以将自身以及相邻基站的小区的动态偏移信息提供给其服务小区的用户设备或者基站本身使用该动态偏移信息进行无线资源管理。例如,本发明中各个小区的小区专用动态偏移是根据该小区的工作情况动态变化的,例如多天线传输性能增益可根据服务的用户数目不同而变化,当用户数目较少时可以采用波束赋形来提高传输质量,当用户数目较多时则无法提供波束赋形的传输服务,小区负载也是根据具体的小区传输业务状态而变化,因此,本发明中设计在相邻基站之间直接交互小区专用动态偏移信息,能够保证该信息的实时性,这与当前通过OAM配置获取邻小区静态特性的方式相比,能够提升无线资源管理的准确性。
在本发明的一个示例中,基站不向用户设备通知小区专用动态偏移信息,而是在从用户设备接收到测量结果后,在基站内部叠加动态偏移来执行比如小区切换等的无线资源管理操作。
在一个示例中,通信单元401对应于X2通信接口,通信单元401通过在X2消息的Cell Information Item中的信息位来交互小区专用动态偏移信息。
根据该实施例的装置400能够实现基于小区专用动态偏移的无线资源管理,提高资源利用效率。
<第六实施例>
在上文的实施方式中描述用于无线通信的用户设备侧和基站侧的装置的过程中,显然还公开了一些处理或方法。下文中,在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要,但是应当注意,虽然这
些方法在描述用于无线通信的用户设备侧和基站侧的装置的过程中公开,但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如,用于无线通信的用户设备侧和基站侧的装置的实施方式可以部分地或完全地使用硬件和/或固件来实现,而下面讨论的用于无线通信的用户设备侧和基站侧的方法可以完全由计算机可执行的程序来实现,尽管这些方法也可以采用用于无线通信的用户设备侧和基站侧的装置的硬件和/或固件。
图5示出了根据本申请的一个实施例的用于无线通信的用户设备侧的方法的流程图,该方法包括如下步骤:获取用户设备的服务小区以及/或者相邻小区的用于无线资源管理的小区专用动态偏移信息(S11),其中,小区专用动态偏移与相应小区的传输能力有关,传输能力包括小区多天线增益、负载情况中至少之一;测量服务小区和相邻小区的参考信号(S12);以及根据用户设备的连接状态,基于小区专用动态偏移以及对服务小区和相邻小区的测量结果进行小区重选或测量报告(S13)。
其中,多天线传输性能增益包括小区预编码增益以及/或者波束赋型增益。小区专用动态偏移还可以与小区负载有关,其中,负载越大,偏移值越小。
在步骤S11中,可以通过***信息或用户设备中记录的历史信息来获取小区专用动态偏移信息。此外,也可以通过从服务小区的基站接收RRC信令来获取服务小区以及相邻小区的小区专用动态偏移信息。
步骤S12中获得的测量结果可以包括与参考信号接收功率和参考信号接收质量中的至少一个相关的测量值。
在步骤S13中,可以基于小区专用动态偏移信息和测量结果来对所测量的小区进行排序,并基于排序结果确定要接入的小区。
在用户设备的无线资源控制连接状态为已连接的情况下,在步骤S11中获取来自用户设备的服务小区的测量配置信息,其中,测量配置信息包含动态偏移以及关于考虑了动态偏移的报告触发事件的测量报告配置。如上所述,可以定义考虑了动态偏移的多个新的报告触发事件。
作为一个示例,包含有小区专用动态偏移信息的测量配置信息包括在RRC指令中。
在步骤S13中,可以至少基于小区专用动态偏移、测量结果以及测量报告配置来触发测量报告。也可以将满足考虑了小区专用动态偏移的报告
触发事件的相邻小区的测量结果包含于测量报告中。
如果在步骤S13中进行的是小区重选,则如图5中的虚线框所示,上述方法还包括步骤S14:在完成小区重选之后,向小区重选的目标小区发送表示在确定时考虑了小区动态偏移的设备能力标记。例如,可以在RRC信令中发送该设备能力标记。
图6示出了根据本申请的一个实施例的用于无线通信的基站侧的方法的流程图,该方法包括如下步骤:生成包含基站的服务小区以及/或者相邻小区的用于无线资源管理的小区专用动态偏移的指示信息(S21),以用于指示基站服务的用户设备,其中,小区专用动态偏移与相应小区的传输能力有关,传输能力包括小区多天线增益、负载情况中至少之一;以及基于小区专用动态偏移进行对用户设备的无线资源管理(S25)。
其中,多天线传输性能增益包括小区预编码增益以及/或者波束赋型增益。小区专用动态偏移还可以与小区负载有关,其中,负载越大,偏移值越小。
