Definitions
- the carrier aggregation technology is that the user terminal can work simultaneously on multiple cells.
- the cells can be continuous or discontinuous in the frequency domain, and the bandwidth of each cell can be the same or different.
- the maximum bandwidth limit per cell is 20 MHz.
- a user terminal aggregates a maximum of five cell formats.
- the LTE-A system also classifies the cells aggregated by the user terminal according to different cells, as follows: Primary Cell (PCell): User terminal aggregates only one cell of multiple cells is defined as PCell The PCell is selected by the base station and configured to the user terminal by using Radio Resource Control (RRC) signaling. Only the Physical Uplink Control Channel (PUCCH) is configured on the PCell.
- RRC Radio Resource Control
- SCell All cells except PCell in all cells aggregated by the user terminal are SCells.
- the LTE-A version (Release, R) 10/R 11 specifies that the User Equipment (UE) can only transmit the PUCCH on the PCell. Therefore, regardless of which carrier (or which transmitting entity) receives downlink signaling (or data) from different cells aggregated by the UE using the same (or different) duplex mode, the uplink transmit power of the UE needs to be upgraded to the macro base station to receive. The extent of the arrival. For example, in different scenarios of R10 UE carrier aggregation, different carriers aggregated by the UE belong to the same base station entity, and scheduling and uplink and downlink data transmission and reception of the UE are controlled by the same base station entity.
- the downlink of the UE can be received through the RRH entity or the repeaters entity, but due to PUCCH/uplink semi-persistent scheduling (Uplink Semi) -Persistent Scheduling, UL SPS and other uplink transmissions are only limited to the primary carrier ( Primary Component On the carrier, PCC, the uplink of the UE needs to be directly received by the base station entity.

Description
一种进行上行移动的方法、 系统和设备 本申请要求在 2012年 5月 24日提交中国专利局、 申请号为 201210163952.6、 发明名称为
"一种进行上行移动的方法、 系统和设备"的中国专利申请的优先权, 其全部内容通过 I用结合 在本申请中。 技术领域 本申请涉及无线通信技术领域, 特别涉及一种进行上行转移的方法、 系统和设备。 背景技术 目前的长期演进(Long Term Evolution, LTE ) 系统, 一个小区中只能有一个载波, 并 且最大带宽为 20Mhz。 对于增强长期演进(LTE-Advanced, LTE-A ) 系统, LTE-A系统的 峰值速率比 LTE系统有了很大的提高, LTE-A系统要求达到下行 lGbps, 上行 500Mbps。 显然, 20Mhz的带宽已经无法满足这种需求。 为了让 LTE-A系统能够符合要求, 引入载波 聚合 ( Carrier Aggregation, CA )技术。
载波聚合技术是用户终端可以在多个小区上同时工作, 这些小区在频域上可以是连续 或者非连续的, 各个小区的带宽可以相同或者不同。 为保持和 LTE系统兼容, 每个小区的 最大带宽限制为 20MHz。 目前一般认为一个用户终端聚合的小区格式最大为 5个。 此外, 基于不同小区可能支持不同功能, LTE-A系统还对用户终端聚合的小区进行了分类,如下: 主小区(Primary Cell, PCell ):用户终端聚合多个小区中只有一个小区被定义为 PCell, PCell由基站选择, 并通过无线资源控制 (Radio Resource Control, RRC )信令配置给用户 终端。只有 PCell上配置有物理层上行控制信道( Physical Uplink Control Channel , PUCCH )。
辅小区 ( Secondary Cell, SCell ): 用户终端聚合的所有小区中除了 PCell之外的小区 都是 SCell。
LTE-A版本( Release, R ) 10/ R 11规定用户设备( User Equipment, UE )仅能在 PCell 上发送 PUCCH。 所以无论 UE聚合的不同小区使用相同 (或不同)的双工方式, 通过从哪 个载波(或哪个发送实体)接收下行信令(或数据 ), 都需要 UE的上行发送功率提升至宏 基站能够接收到的程度。 比如 R10 UE载波聚合的不同场景, UE聚合的不同载波属于同一 个基站实体, UE 的调度与上下行数据收发均由同一个基站实体控制。 即使通过远端射频 头 (Remote Radio Heads, RRH )射频拉远或者使用中继器(repeaters )补充覆盖, UE的 下行可以通过 RRH实体或者 repeaters实体接收, 但由于 PUCCH/上行半持续调度( Uplink Semi-Persistent Scheduling , UL SPS 等上行传输仅限制在主载波 ( Primary Component
Carrier, PCC )上, 需要由基站实体直接接收 UE的上行。
对于 LTE R10/R11版本的 UE, 其仅能聚合同一个基站的载波资源, 因此按照目前的 测量机制, 基站可以确定 UE通过哪个小区进行数据传输, 从而减少千扰并节电。
但是 R12版本的 UE有可能同时聚合多个基站的资源, 如果本地节点处于宏覆盖下, 对 于处于本地节点覆盖下距离宏基站稍远的 UE , 仍保持其 PUCCH/UL SPS等上行传输仅在 PCC 上的限制, 会增加千扰并且不利于 UE节电。 发明内容 本申请实施例提供的一种进行上行转移的方法、 系统和设备, 用以解决现有技术中存 在的本地节点处于宏覆盖下, 对于处于本地节点覆盖下距离宏基站稍远的 UE仍保持其上 行传输仅由 PCC接收的限制, 会增加千扰并且不利于 UE节电的问题。

第二处理模块, 用于将所述用户设备的上行转移到确定的本地节点。
本申请实施例提供的一种进行上行转移的系统, 包括:

为其选择路损较小的本地节点接收 UE的上行信号, 从而降低 UE的发射功率, 减少千扰 并且节省 UE的电量。
其中, 本申请实施例中的本地节点包括但不限于下列中的至少一个:
低功率基站(Pico )小区、 家庭基站(Femto )、 RRH、 repeaters ^ 中继设备(RN )、 宏 基站(Macro基站)。
下面结合说明书附图对本申请实施例作进一步详细描述。
其中, 本申请实施例可以由网络侧设备根据路损值, 判断用户设备的上行是否需要转 移;还可以由用户设备根据路损值,判断用户设备的上行是否需要转移并上报网络侧设备, 下面分别进行介绍。
一、 网络侧设备根据路损值, 判断用户设备的上行是否需要转移。
如图 1所示, 本申请实施例第一种进行上行转移的方法包括下列步骤:
步骤 101、 网络侧设备根据用户设备与至少一个本地节点之间的路损值以及用户设备 与网络侧设备之间的路损值, 判断用户设备的上行是否需要转移;
步骤 102、 网络侧设备在确定用户设备的上行需要转移后, 将用户设备的上行转移到 本地节点上。
较佳地, 步骤 101中, 网络侧设备确定用户设备与本地节点之间的路损值的方式有很 多种, 下面列举几种:
方式一、 网络侧设备根据至少一个本地节点的参考信号功率值和用户设备上报的参考 信号接收功率值, 确定用户设备与本地节点之间的路损值。
其中, 如果只需要确定用户设备与一个本地节点之间的路损值, 则根据这个本地节点 的参考信号功率值和用户设备上报的参考信号接收功率值, 确定用户设备与这个本地节点 之间的路损值。 如果需要确定用户设备与两个或两个以上本地节点之间的路损值, 则分别 确定用户设备与每个本地节点之间的路损值; 具体的, 根据一个本地节点的参考信号功率 值和用户设备上报的针对这个本地节点的参考信号接收功率值, 确定用户设备与这个本地 节点之间的路损值。
在实施中, 网络侧设备根据至少一个本地节点的参考信号功率值和用户设备上报的参 考信号接收功率值, 确定用户设备与本地节点之间的路损值的方式有很多种。 比如网络侧 设备可以通过获取的其他节点的参考信号功率信息, 和通过 UE 的无线资源管理(Radio Resource Magagement, RRM )测量上报内容, 确定 UE与不同本地节点之间的路损值。
具体的, 网络侧设备通过获取的其他节点的参考信号接收功率信息, 得到 UE的至少 一个本地节点的参考信号功率值, 通过 UE的 RRM测量上报内容得到测量参考信号接收 功率值, 根据得到的本地节点的参考信号功率值和针对该本地节点的参考信号接收功率值 确定 UE与该本地节点之间的路损值。 本申请实施例中, 其他节点是指网络侧设备之外的
节点, 包括 UE的至少一个本地节点。
RIO UE上报的 RRM测量上报内容中可以携带多个服务小区的信号强度和 /或信号盾 量。 网络侧设备通过收到的多个服务小区的信号测量量 (信号测量量即参考信号接收功 率), 与本地节点的发射功率差异, 可以判断 UE是否距离本地节点较近, 进而判断是否将 UE的上行全部转移至本地节点以降低 UE的上行发生功率, 节省 UE电量, 具体可以参见 图 10。
网络侧设备根据至少一个本地节点的参考信号功率值和用户设备上报的参考信号接 收功率值, 确定用户设备与本地节点之间的路损值的公式可以参见 3GPP TS 36.213协议, 在此不再赘述。
较佳地, 网络侧设备可以通过操作、 管理与维护 (Operation Administration and
Maintenance, OAM )设备获取至少一个本地节点的参考信号功率值; 和 /或通过 X2或 S1 接口获取至少一个本地节点的参考信号功率值。
其中, 本申请实施例的参考信号功率值可以是小区专用参考信号 (Cell-specific reference signals, CRS )功率值, 或信道状态信息测量参考信号 ( CSI-RS )功率值。
X2接口是基站之间的接口,完成基站之间的用户数据传送、用户数据及信令的处理等
S1 接口是无线接入网节点与核心网节点间建立的逻辑接口, 具体又分为控制面接口 ( S1-MME )和用户面接口 (Sl-U )。 S1-MME是无线接入网节点与 MME之间建立的逻辑 接口, 用于传输控制面信令(信令具体内容参见 3GPP TS36.413 )。 S1-U是无线接入网节 点与 SGW之间建立的逻辑接口, 用于传输用户面数据 (用户面数据包格式参见 3GPP TS29.281 )。
方式二、 网络侧设备接收到来自用户设备的与至少一个本地节点之间的路损值。
如果需要用户设备上报路损值, 则网络侧设备获得其他节点的参考信号功率后, 将其 下发给用户设备, 使得用户设备可以获知不同本地节点的下行参考信号功率, 由于用户设 备能够测量到不同本地节点的下行参考信号接收功率 (Reference signal received power, RSRP ), 从而可以自行计算到不同本地节点的路损值。
如果有多个本地节点, 用户设备可以将这些节点按照路损值从小到大排序, 并上 4艮前 N个节点的标识信息, N是正整数。
R10 载波聚合中, UE 能够通过广播(或专用信令)接收主小区的系统信息, 以及通 过专用信令获取辅小区的系统信息, 从信息元素 (IE ) 物理下行共享信道公共配置 ( PDSCH-ConfigCommon ) 中获取主 /辅小区的 CRS 功率, 可以测量主 /辅小区的 RSRP 值并利用路损公式, 计算出 UE与各小区之间的路损。 本申请实施例中的本地节点, 由于 其与宏基站可能处于不同地理位置, 并且本地节点与宏基站所在的频点并不一致, 需要重 新计算 UE与本地节点之间的路损。
用户设备在确定路损值时 "参考信号功率" 与 "参考信号接收功率" 需要设为对同类 的参考信号的参数, 只能同时均为 CRS的, 或者均为 CSI-RS的。 所以如果网络交互的为 CSI-RS功率, UE测量的接收功率也要是 CSI-RS的。 比如使用 CSI-RS参考信号, 需要通 过 OAM或 X2/S1口通知 CSI-RS功率, 并下发给 UE, UE需要使用 CSI-RS参考信号进行 RSRP等的测量。
较佳地, 若有多个本地节点, 步骤 101和步骤 102之间还可以进一步包括: 网络侧设备选择接纳用户设备的上行的本地节点;
相应的, 步骤 102中, 网络侧设备将用户设备的上行转移到选择的本地节点上。 较佳地, 步骤 102中, 网络侧设备将用户设备的上行转移到有足够的资源接纳用户设 备的上行的本地节点上。
若只有一个本地节点, 则网络侧设备在确定用户设备的上行需要转移后, 还需要查看 该本地节点是否有足够的资源接纳用户设备的上行, 如果有, 则将用户设备的上行转移到 有足够的资源接纳用户设备的上行的本地节点上; 否则不进行转移。
若有多个本地节点, 则网络侧设备从有足够的资源接纳用户设备的上行的本地节点 中, 选择一个接纳 UE的上行的本地节点。
较佳地, 步骤 102中, 网络侧设备将用户设备与网络侧设备的路损值分别与用户设备 与至少一个本地节点之间的路损值进行比较;
若用户设备与至少一个本地节点之间的路损值中有小于用户设备与网络侧设备的路 损值, 确定用户设备的上行需要转移; 否则确定用户设备的上行不需要转移。
在实施中, 若用户设备与至少一个本地节点之间的路损值中有多个路损值小于用户设 备与网络侧设备的路损值, 则网络侧设备从对应的路损值小于用户设备与网络侧设备的路 损值的本地节点中, 选择一个本地节点。
比如用户设备与本地节点 A之间的路损值小于用户设备与网络侧设备的路损值,用户 设备与本地节点 B之间的路损值小于用户设备与网络侧设备的路损值; 则网络侧设备可以 从本地节点 A和 B中选择一个本地节点。
较佳地, 若用户设备与至少一个本地节点之间的路损值中有多个路损值小于用户设备 与网络侧设备的路损值, 则网络侧设备可以选择对应的路损值最小的本地节点。 选择对应 的路损值最小的本地节点, 即选择与用户设备之间的路损值最小的本地节点。
较佳地, 步骤 102中, 若用户设备与至少一个本地节点之间的路损值中有多个路损值 小于用户设备与网络侧设备的路损值, 网络侧设备从对应的路损值小于用户设备与网络侧 设备的路损值的本地节点中, 选择有足够的资源接纳用户设备的上行的本地节点。
比如用户设备与本地节点 A之间的路损值小于用户设备与网络侧设备的路损值,用户 设备与本地节点 B之间的路损值小于用户设备与网络侧设备的路损值,且本地节点 A有足
够资源接纳, 则网络侧设备选择本地节点 A。
较佳地, 网络侧设备可以从足够资源接纳中选择路损最小的, 或从对应的路损值小于 用户设备与网络侧设备的路损值的本地节点中, 选择足够的资源最多的本地节点。
本申请实施例中, 上行转移是指, 通过选择的本地节点接收用户设备的上行。 那么, 将用户设备的上行转移到本地节点的具体实现方式可以是, 通知该本地节点接收用户设备 的上行。
较佳地, 步骤 102中, 网络侧设备在确定用户设备的上行需要转移后, 通知选择的本 地节点接收用户设备的 PUCCH ( Physical Uplink Control Channel , 物理上行控制信道)。
较佳地, 步骤 102中, 网络侧设备在确定用户设备的上行需要转移后, 还可以向用户 设备发送配置信令, 用于通知用户设备降低上行发射功率。
用户设备降低上行发射功率的具体方式可以参见 3GPP TS 36.213协议,在此不再赘述。 其中, 本申请实施例至少一个本地节点中全部本地节点归属于网络侧设备或部分本地 节点归属于网络侧设备或全部本地节点不属于网络侧设备。
基于同一发明构思, 本申请实施例中还提供了一种网络侧设备, 由于该网络侧设备解 决问题的原理与本申请实施例第一种进行上行转移的方法相似, 因此该网络侧设备的实施 可以参见方法的实施, 重复之处不再赘述。

其中, 本申请实施例的网络侧设备可以 ^&站(比如宏基站、 家庭基站等), 也可以 是 RN (中继)设备, 还可以是其它网络侧设备。
在实施中, 本申请实施例的网络侧设备是用户设备接入的小区所属的网络侧设备。 二、 用户设备根据路损值, 判断用户设备的上行是否需要转移并上报网络侧设备。 在下面的说明过程中, 先从网络侧和用户设备侧的配合实施进行说明, 最后分别从网 络侧与用户设备侧的实施进行说明, 但这并不意味着二者必须配合实施, 实际上, 当网络 侧与用户设备侧分开实施时, 也解决了分别在网络侧、 用户设备侧所存在的问题, 只是二 者结合使用时, 会获得更好的技术效果。
如图 3所示。 本申请实施例第二种进行上行转移的方法包括下列步骤:
步骤 301、 用户设备根据用户设备与至少一个本地节点之间的路损值以及用户设备与 网络侧设备之间的路损值, 判断用户设备的上行是否需要转移;
步骤 302、 用户设备在确定上行需要转移后, 向网络侧设备发送需要转移上行的通知; 步骤 303、 网络侧设备接收到来自用户设备的需要转移上行的通知后, 确定接纳用户 设备的上行的本地节点;
步骤 304、 网络侧设备将用户设备的上行转移到确定的本地节点。
较佳地, 步骤 301中, 用户设备根据至少一个本地节点的参考信号功率值和小区参考 信号接收功率值, 确定用户设备与本地节点之间的路损值。
其中, 网络侧设备获得其他节点的参考信号功率后, 将其下发给用户设备, 使得用户 设备可以获知不同本地节点的下行参考信号功率, 由于用户设备能够测量到不同本地节点 的下行 RSRP, 从而可以自行计算到不同本地节点的路损值。
较佳地, 本申请实施例的参考信号功率值是 CRS功率值或 CSI-RS功率值
若使用 CSI-RS参考信号, 网络侧设备需要通过 OAM或 X2/S1口通知 CSI-RS功率,
并下发给 UE, UE需要使用 CSI-RS参考信号进行 RSRP等的测量。
其中, 用户设备计算到不同本地节点的路损值的方法可以参见 36.213协议, 在此不再 赘述。
步骤 301中, 用户设备判断用户设备的上行是否需要转移的方式有很多种, 下面列举 两种。
判断方式一、 用户设备将用户设备与网络侧设备的路损值分别与用户设备与至少一个 本地节点之间的路损值进行比较;
若用户设备与至少一个本地节点之间的路损值中有小于用户设备与网络侧设备的路 损值, 确定用户设备的上行需要转移; 否则确定用户设备的上行不需要转移。
相应的, 用户设备将对应的路损值中有小于用户设备与网络侧设备的路损值的本地节 点的标识通知置于需要转移上行的通知中。
如果能够通知多个本地节点, 用户设备可以将这些节点的标识按照路损值从小到大排 序, 并将前 N个节点的标识信息置于需要转移上行的通知中, N=l , 2, 3....。
判断方式二、 用户设备根据 Offset' (偏移量)在确定与至少一个本地节点之间的路损 值中有小于用户设备与网络侧设备的路损值后,触发 A3测量事件,并将 A3测量事件的测 量结果作为需要转移上行的通知;
其中, Offset' 是网络侧设备与本地节点之间的参考信号功率差值。
具体的, 判断方式二中, 利用了现有的 A3测量事件: 邻小区信号强度优于服务小区 ( PCell )信号强度。 其中服务小区只能是 PCell, 而邻小区可以是 SCell, 或者 non- serving cell (非服务小区)。
网络侧设备获得其它节点的参考信号功率值后, 与本基站的参考信号功率值做差值, 将差值下发给 UE作为触发 A3测量事件的偏移量之一或将其它节点的参考信号功率值和 本基站的参考信号功率值通知用户设备, 由用户设备自己计算差值并将差值作为触发 A3 测量事件的偏移量之一。
用户设备在满足公式一后, 确定与至少一个本地节点之间的路损值中有小于用户设备 与网络侧设备的路损值,并且触发进行 A3测量事件的上报,将 A3测量事件的测量结果作 为需要转移上行的通知。
本地节点的信号>宏基站信号 +Offset+ Offset' 公式一。
其中, Offset' 是本地节点与宏基站的参考信号功率的差值; Offset可以为频点偏移、 小区偏移、 事件本身偏移量中的一种或多种的累加。
较佳地, 步骤 303中, 网络侧设备由需要转移上行的通知确定的本地节点中选择有足 够的资源接纳用户设备的上行的本地节点。
具体的, 若釆用判断方式一, 网络侧设备可以从需要转移上行的通知中选择一个标识
对应的本地节点作为接纳用户设备的上行的本地节点。
若需要转移上行的通知中只有一个标识, 则网络侧设备还需要查看标识对应的本地节 点是否有足够的资源接纳用户设备的上行, 如果有, 则将用户设备的上行转移到有足够的 资源接纳用户设备的上行的本地节点上; 否则不进行转移。
若需要转移上行的通知中有多个本地节点, 则网络侧设备从多个标识对应的本地节点 中确定有足够的资源接纳用户设备的上行的本地节点, 并从有足够的资源接纳用户设备的 上行的本地节点中选择一个接纳 UE的上行的本地节点; 若有足够的资源接纳用户设备的 上行的本地节点, 则不进行转移。
较佳地, 网络侧设备可以从足够资源接纳中选择路损最小的, 或从对应的路损值小于 用户设备与网络侧设备的路损值的本地节点中, 选择足够的资源最多的本地节点。
具体的, 若釆用判断方式二, 由于用户设备进行 A3测量和上 4艮一次只针对一个本地 节点, 所以进行 A3上报后网络侧设备就可以确定对应的本地节点; 然后网络侧设备进一 步判断该本地节点是否有足够的资源接纳用户设备的上行, 若有, 则将用户设备的上行转 移到有足够的资源接纳用户设备的上行的本地节点上; 否则不进行转移。
具体的方式与图 1的方法类似, 在此不再赘述。
若釆用判断方式一, 步骤 301之前还包括:
网络侧设备将网络侧设备和至少一个本地节点的参考信号功率值发送给用户设备, 用 于通知用户设备根据参考信号功率值确定用户设备与至少一个本地节点之间的路损值以 及确定用户设备与网络侧设备之间的路损值。
在实施中, 网络侧设备通过 OAM设备获取至少一个本地节点的参考信号功率值; 和 / 或通过 X2或 S 1接口获取至少一个本地节点的参考信号功率值。
较佳地, 参考信号功率值是 CRS功率值或 CSI-RS功率值。
若釆用判断方式二, 步骤 301之前还包括:
网络侧设备将网络侧设备与至少一个本地节点之间的参考信号功率差值作为偏移量 Offset' 发送给用户设备, 用于通知用户设备根据 Offset' 在确定与至少一个本地节点之间 的路损值中有小于用户设备与网络侧设备的路损值后, 触发 A3测量事件。
较佳地, 步骤 304中, 网络侧设备通知选择的本地节点接收用户设备的 PUCCH。 较佳地, 步骤 304中, 网络侧设备向用户设备发送配置信令; 相应的, 用户设备根据 收到的来网络侧设备的配置信令, 降低上行发射功率。 即, 在将用户设备的上行转移到确 定的本地节点过程中后完成后, 还向用户设备发送配置信令, 用于通知用户设备降低上行 发射功率。
较佳地, 至少一个本地节点中全部本地节点归属于网络侧设备或部分本地节点归属于 网络侧设备或全部本地节点不属于网络侧设备。

较佳地, 若网络侧设备接收到来自用户设备的需要转移上行的通知是 A3测量事件的 测量结果; 确定模块 710将网络侧设备与至少一个本地节点之间的参考信号功率差值作为 偏移量 Offset' 发送给用户设备, 用于通知用户设备根据 Offset' 在确定与至少一个本地节 点之间的路损值中有小于用户设备与网络侧设备的路损值后, 触发 A3测量事件的上报; 或将网络侧设备的参考信号功率值和至少一个本地节点的参考信号功率值发送给用户设 备, 用于通知用户设备根据网络侧设备的参考信号功率值和至少一个本地节点的参考信号 功率值确定 Offset' , 并根据 Offset' 在确定与至少一个本地节点之间的路损值中有小于用 户设备与网络侧设备的路损值后, 触发 A3测量事件的上报。
