Description

用于载波聚合系统中的上下行分量载波链接的方法和设备 技术领域
[01] 本发明涉及移动通信领域, 特别涉及一种用于载波聚合系统中的上行分 量载波和下行分量载波链接的方法和设备。 背景技术
[02] 随着由第三代合作伙伴计划 ( 3rd Generation Partnership Project , 3GPP ) 启动的通用移动通信系统 ( Universal Mobile Telecommunications System , UMTS )技术长期演进 ( Long Term Evolution, LTE )项目的冻结, 3GPP组织 已经开始了对第四代移动通信系统高级长期演进 (LTE-Advanced, LTE-A)技术 的研究。 为了满足国际电信联盟( International Telecommunication Union, ITU ) 提出的针对 4G系统的下行 lGbps、 上行 500Mbps的高数据速率要求, 3GPP 在 LTE-A 中提出了载波聚合技术以支持能够提供该速率要求的带宽值。 载波 聚合技术可以把不同频段的多个载波聚合起来组成最大 100M 的带宽, 使 LTE-A的用户设备 ( User Equipment, UE ) 可以在多个载波上接收和 /或发送 数据, 从而使发送或接收数据的带宽大于 20M。 在载波聚合技术中, 每个聚 合的载波称为一个分量载波 ( component carrier, CC )。
[03] 在载波聚合系统中基站端将部署多个载波, 而终端也将支持同时在多个 载波上进行数据的发送和接收。这为载波聚合的研究提出了许多新的问题。如 何建立上下行分量载波的链接关系是其中一个需要解决的问题。 在 LTE 系统 中只有一对上下行载波,因此其链接关系是唯一的。通过这种唯一的链接关系, 可以确定:
[04] 1.用户设备接收到下行数据后用来进行反馈确认的上行载波;
[05] 2.基站接收到数据后用来进行反馈确认的下行载波;
[06] 3.基站接收到用户设备的随机接入信息后用来发送响应的下行载波;以及 [07] 4.用户设备接收到上行资源分配信息后,该上行资源分配信息所对应的上 行载波。
[08] 在载波聚合系统中, 由于同时存在多对上下行分量载波, 因此, 在为用 户设备配置分量载波时,需要显式地通知用户设备所配置的上下行分量载波针 对上述四种情况的链接关系。 目前在 LTE-A系统中关于载波聚合方面的讨论 已经给出了以下结论:
[09] 协定 1 : 用户设备收到下行数据后, 对来自任何下行载波的数据的反馈 确认只会通过一个主分量载波进行反馈。
[10] 协定 2: 基站对用户上行数据的反馈确认只会通过传输该上行数据资源 分配信息的下行分量载波进行反馈。例如,如果基站通过下行分量载波 CC1 为 用户设备在上行载波 CC1上分配上行资源, 则在收到用户设备来自上行分量 载波 CC1的数据时, 基站会通过下行分量载波 CC1对该上行数据进行反馈确 认。
[11] 协定 3: 在某些情况下, 基站对用户设备可以进行跨分量载波调度。 例 如,基站可以通过下行分量载波 CC1为用户设备在上行分量载波 CC2 上分配 上行资源。 这时, 基站会在资源分配信息中包含上行分量载波 CC2的载波索 引 ( Carrier Index, CI )值, 通过该载波索引值, 用户设备可以知道该资源分 配信息所对应的上行载波为 CC2。
[12] 通过上述三个结论可以发现:
[13] · 不需要建立传输下行数据的下行分量载波和传输上行反馈确认的上行 分量载波的链接关系。
[14] · 不需要建立传输上行数据的上行分量载波和传输下行反馈确认的下行 分量载波的链接关系。
[15] · 基站为用户配置了跨载波调度时, 不需要建立传输上行资源分配信息 的下行分量载波和该上行资源分配信息所对应的上行分量载波的链接关系。
[16] 因此, 只需要针对下面两种情况建立上下行分量载波之间的链接关系:
[17] (1)基站接收到用户设备通过上行分量载波发送的随机接入信息后根据上 下行分量载波的链接关系确定用来发送响应的下行分量载波 (以下筒称为上- 下链接关系) 。
[18] (2)在没有配置跨载波调度的情况下, 用户设备在下行分量载波上接收到 上行资源分配信息后,根据上下行分量载波之间的链接关系确定该上行资源分 配信息所对应的上行分量载波(以下筒称为下-上链接关系) 。
[19] 针对上述两种情况如何建立上下行载波分量的链接关系, 目前已经给出 了一种方法, 即利用目前 LTE系统的下行广播信息 SIB2(System Information Block 2)。在下行载波传输的 SIB2中会包含其所链接的上行载波的频率和带宽 信息。 当基站为用户设备配置或移除成对的上下行载波时, 该方法可以建立上 下行分量载波之间的链接关系。然而,当基站为用户设备单独配置或移除上 (或 下)行分量载波时, 该方法并不能有效解决上下行分量载波之间的链接关系。 例如:
[20] 场景一:
[21] 如图 1所示,在初始时刻基站为 UE1和 UE2均配置了载波对 {DL #1 , UL#1 } 和 {DL#2, UL#2}。 在此后某一时刻, 基站为 UE1增加配置了载波对 {DL#3 , UL#3 } , 但只为 UE2增加配置了下行载波 {DL#3 }。 对于 UEl , DL#3和 UL#3 可以根据 SIB2建立链接关系, 但对于 UE2, DL#3需要与 UL#1或 UL#2建立 链接关系。 因此如果仍然按照 SIB2的内容, UE2将无法正确得到与 DL#3链 接的上行载波。
[22] 场景二:
[23] 如图 2所示, 在初始时刻基站为 UE1和 UE2均配置了载波对 {DL #1 , UL#1 } , {DL#2, UL#2}和 {DL#3 , UL#3}。 在此后某一时刻, UE2 的 UL#3 发生了链路故障, 无法使用。 这时, 基站会将 UL#3从 UE2的载波集合中移 除。 如果仍然按照 SIB2的内容, UE2将无法正确得到与 DL#3的链接的上行 载波。 因此需要重新为 UE2建立 DL#3的链接关系。
[24] 为了解决类似上述上行载波或下行载波单独配置时 (包括增加、 移除或 替换) 出现的上下行载波之间的链接关系的问题, 提出了本发明。 发明内容

[52] 图 3是示出根据本发明实施例的用于载波聚合系统中的上行分量载波和 下行分量载波链接的设备 100的框图。
[53] 如图 3所示, 根据本发明的设备 100包括载波索引配置装置 110和信令 发送装置 120。 [54] 载波索引配置装置 110 用于向成对的上行分量载波和下行分量载波或者 单独的上行分量载波或下行分量载波分配载波索引,将载波索引与成对的上行 分量载波和下行分量载波或者单独的上行分量载波或下行分量载波进行绑定, 以确定载波索引与成对的上行分量载波和下行分量载波或者单独的上行分量 载波或下行分量载波之间的映射关系。
[55] 信令发送装置 120用于在同时增加、 移除或替换一对上行分量载波和下 行分量载波或者增加、移除或替换单独的下行分量载波或上行分量载波的情况 下, 将载波增加信令、 载波移除信令或载波替换信令发送到用户设备, 从而有 效建立上下行分量载波之间的链接关系。
[56] 针对同时增加、 移除或替换一对上行分量载波和下行分量载波或者增加、 移除或替换单独的下行分量载波或上行分量载波的情况,可以分为以下九种场 景:
[57] · 同时增加一对上下行分量载波
[58] · 增加单独的下行分量载波
[59] · 增加单独的上行分量载波
[60] · 同时移除一对上下行分量载波
[61] · 移除单独的下行分量载波
[62] · 移除单独的上行分量载波
[63] · 同时替换一对上下行分量载波
[64] · 替换单独下行分量载波
[65] · 替换单独上行分量载波
[66] 下面分别针对上述 9种场景对本发明的实施例进行说明。
(1 )同时增加一对上下行分量载波
[67] 图 4 ( a ) -4 ( c )是示出根据本发明实施例的同时增加一对上下行分量载 波的场景的示意图。
[68] 如图 4 ( a )所示, 在初始时刻基站为用户设备 UE配置了分量载波对 {DL #0, UL#0}。 在此后某一时刻, 由于例如基站和 UE之间的上下行数据量增加 等等的原因, 基站为 UE增加配置分量载波对 {DL#1 , UL#1 }。 在这种情况下, 在根据本发明的方法中, 向分量载波对 {DL#1, UL#1}分配载波索引 CI, 将 CI与 {DL#1, UL#1}进行绑定, 以确定 CI与 {DL#1, UL#1 }之间的映射关系。 该映射关系可以是用户设备专用的 ( UE-specific ), 也可以是小区专用的 ( cell-specific )。 这可以由根据本发明的设备 100 中的载波索引配置装置 110 来实现。
[69] 在根据本发明的方法中, 将载波增加信令发送到 UE, 以同时增加一对分 别建立了下 -上和上-下链接关系的上行分量载波和下行分量载波 {DL#1, UL#1}。 在载波增加信令中需要包含如下内容:
- CarrierFreq: {dl-carrierFreq; ul-CarrierFreq} - CarrierB andwidth: {dl-bandwidth; ul-bandwidth }
- Carrier Index(CI)
[70] 其中, 在载波频率 CarrierFreq域中需要包含下行分量载波 DL#1 的载波 频率 dl-carrierFreq和上行分量载波 UL # 1的载波频率 ul-CarrierFreq, 在载波 带宽 CarrierBandwidth 域中需要包含下行分量载波 DL#1 的载波带宽 dl-bandwidth和上行分量载波 UL # 1的载波带宽 ul-bandwidth, 并且在载波索 引 Carrier Index(CI)中需要包含向分量载波对 {DL#1 , UL#1}分配的载波索引 CL
[71] 载波增加信令的发送可以由根据本发明的设备 100中的信令发送装置 110 来完成。 UE在接收到上述载波增加信令之后, 即可在基站与 UE之间有效建 立上行分量载波 UL# 1和下行分量载波 DL#1之间的下-上和上-下链接关系。
[72] 如图 4(b)所示,在初始时刻基站为 UE配置了分量载波对 {DL#0,UL#0}, 另外下行分量载波 DL # 1还与上行分量载波 UL # 0建立了下 -上链接关系。在 此后某一时刻, 基站为 UE增加配置了分量载波对 {DL#2, UL#2}。 如图 4(c) 所示, 在初始时刻基站为 UE配置了分量载波对 {DL#0, UL#0}, 另外上行分 量载波 UL # 1还与下行分量载波 DL # 0建立了上-下链接关系。在此后某一时 刻, 基站为 UE增加配置了分量载波对 {DL#2, UL#2}。
[73] 对于如图 4 (b)和 4 (c)所示的同时增加一对上下行分量载波的两种情 况, 针对载波进行配置的方式与对于如图 4 (a)所示的情况类似, 不同之处 仅在于将图 4 (a) 中的上行分量载波 UL#1和下行分量载波 DL#1分别替换 为图 4 (b)和 4 (c) 中的上行分量载波 UL#2和下行分量载波 DL#2, 故此 不再赘述。
(2 )增加单独的下行分量载波
[74] 图 5 (a) -5 (c)是示出根据本发明实施例的增加单独的下行分量载波的 场景的示意图。
[75] 如图 5 (a)所示, 在初始时刻基站为用户设备 UE配置了分量载波对 {DL #0, UL#0}。 在此后某一时刻, 由于例如从基站发送到 UE的下行数据量增加 等等的原因, 基站决定将下行分量载波 DL#1与一个已经与下行分量载波建 立一对一链接关系的上行分量载波(亦即已经与 DL#0建立一对一链接关系 的 UL#0)建立链接关系。 在这种情况下, 在根据本发明的方法中, 向单独的 下行分量载波 DL# 1分配载波索引 CI。 这可以由根据本发明的设备 100中的 载波索引配置装置 110来实现。
[76] 在根据本发明的方法中, 将载波增加信令发送到 UE, 以增加仅建立与单 独的下行分量载波 DL#1的下-上链接关系的下行分量载波 DL#1。 在载波增 加信令中需要包含如下内容:

[79] 根据上述内容, 新增加的下行分量载波 DL#1可以与 Linkage中指示的 上行分量载波(亦即 UL#0)建立下-上链接关系, 而 Linkage 中指示的上行 分量载波(亦即 UL # 0 )继续与之前的下行分量载波(亦即 DL # 0 )保持上- 下链接关系。
[80] 载波增加信令或载波激活信令的发送可以由根据本发明的设备 100 中的 信令发送装置 110来完成。 UE在接收到上述载波增加信令或载波激活信令之 后, 即可在基站与 UE之间有效建立下行分量载波 DL#1 和上行分量载波 UL#0之间的下-上链接关系。
[81] 如图 5(b)所示,在初始时刻基站为 UE配置了分量载波对 {DL#0,UL#0} 和 {DL #1, UL#1}。 在此后某一时刻, 基站决定将下行分量载波 DL# 2与一 个已经与下行分量载波建立一对一链接关系的上行分量载波(亦即已经与 DL # 1建立一对一链接关系的 UL # 1 )建立链接关系。
[82] 对于如图 5 (b)所示的增加单独的下行分量载波的情况, 针对载波进行 配置的方式与对于如图 5 (a)所示的情况类似, 不同之处仅在于将图 5 (a) 中的上行分量载波 UL#0和下行分量载波 DL#1分别替换为图 5 (b) 中的上 行分量载波 UL # 1和下行分量载波 DL#2, 故此不再赘述。
[83] 如图 5(c)所示,在初始时刻基站为 UE配置了分量载波对 {DL#0,UL#0}, 另外上行分量载波 UL # 1还与下行分量载波 DL # 0建立了上-下链接关系。在 此后某一时刻, 基站决定将下行分量载波 DL#1与一个已经与下行分量载波 建立多对一链接关系的上行分量载波(亦即已经与 DL#0建立多对一链接关 系的 UL # 1 )建立链接关系。
[84] 在这种情况下, 在根据本发明的方法中, 将载波增加信令发送到 UE, 以 增加分别建立与单独的上行分量载波 UL#1 的下-上和上 -下链接关系的下行 分量载波 DL#1。 在载波增加信令中需要包含如下内容:
- CarrierFreq: {dl-carrierFreq }
- CarrierB andwidth: { dl-bandwidth }
[85] 其中, 在载波频率 CarrierFreq域中需要包含单独的下行分量载波 DL#1 的载波频率 dl-carrierFreq , 并且在载波带宽 CarrierBandwidth域中需要包含单 独的下行分量载波 DL#1的载波带宽 dl-bandwidth。
[86] 而以下内容可以在下行载波增加信令中包含, 也可以在下行载波激活信 令中包含:
- Linkage: 连接的上行分量载波的 CI值 [87] 根据上述内容, 新增加的下行分量载波 DL # 1可以与 Linkage中指示的 上行分量载波(亦即 UL # 1 )分别建立下 -上链接关系和上-下链接关系。
[88] 载波增加信令或载波激活信令的发送可以由根据本发明的设备 100 中的 信令发送装置 110来完成。 UE在接收到上述载波增加信令或载波激活信令之 后, 即可在基站与 UE之间有效建立下行分量载波 DL # 1 和上行分量载波 UL#1之间的下-上链接关系和上 -下链接关系。

[95] 载波增加信令的发送可以由根据本发明的设备 100中的信令发送装置 110 来完成。 UE在接收到上述载波增加信令之后, 即可在基站与 UE之间有效建 立上行分量载波 UL# 1和下行分量载波 DL#0之间的上-下链接关系。
[96] 如图 6(b)所示,在初始时刻基站为 UE配置了分量载波对 {DL#0,UL#0} 和 {DL #1, UL#1}。 在此后某一时刻, 基站决定将上行分量载波 UL# 2与一 个已经与上行分量载波建立一对一链接关系的下行分量载波(亦即已经与 UL # 1建立一对一链接关系的 DL # 1 )建立链接关系。
[97] 对于如图 6 (b)所示的增加单独的上行分量载波的情况, 针对载波进行 配置的方式与对于如图 6 (a)所示的情况类似, 不同之处仅在于将图 6 (a) 中的下行分量载波 DL#0和上行分量载波 UL#1分别替换为图 6 (b) 中的下 行分量载波 DL # 1和上行分量载波 UL#2, 故此不再赘述。
