Abstract

本申请提供上行控制信息处理方法及传输点、终端。一种上行控制信息处理方法可以通过第一传输点为终端确定待增加的第二传输点，进而由第一传输点向终端发送指示信息，指示信息用以指示第二传输点的上行控制信息在第二传输点的物理上行控制信道上传输。通过本发明实施例，为终端提供下行传输的传输点的上行控制信息不再需要通过这两个传输点之间的路径传递给为终端提供下行传输的传输点，而是，直接由终端传递给为终端提供下行传输的传输点，从而降低了上行控制信息的传输开销和传输时延。

Description

上行控制信息处理方法及传输点、 终端
技术领域
本申请涉及通信技术， 尤其涉及上行控制信息处理方法及传输点、 终端。 背景技术
在无线通信系统例如： 长期演进（ Long Term Evolution, LTE )系统中， 用户设备（ User Equipment, UE )上报给演进型基站（ Evolved NodeB, eNB ) 的上行控制信息（Uplink Control Information, UCI )是由物理上行控制信道 ( Physical Uplink Control Channel, PUCCH )物理上行信道承载的。 UCI 可以包括下行数据的反馈信息（即下行数据被正确接收的 ACK信息或没有被 正确接收的 NACK信息）、上行数据的调度请求（ Scheduling Request, SR ) 信息和信道状态信息 ( Channel Status Information , CSI )等中的至少一项。 由于协作多点 （ Coordinated Multiple Points, CoMP ) 、 载波聚合（ Carrier Aggregation, CA )等技术的引入， 终端可能会有多个传输点（ Transmission Point, TP )同时为其服务。 此时， 终端需要上报针对每个传输点的上行控制 信息。
在某些网络部署场景例如，异构网络（ Heterogeneous Network, Hetnet ) 部署场景中， 越来越多的微基站按需被布放到原来只有宏基站实现全覆盖的 网络中， 由于每个传输点即宏基站或微基站与终端的距离不同， 以及每个传 输点的发射功率不同， 因此， 为终端提供上行传输的传输点与为终端提供下 行传输的传输点可能会不一致。 例如， 如果终端与啟基站的距离小于该终端 与宏基站的距离， 那么， 该终端则可以通过微基站进行上行传输； 虽然终端 与微基站的距离小于该终端与宏基站的距离， 但是， 由于宏基站的发射功率 比 基站的发射功率大的多， 因此， 该终端则可以通过宏基站进行下行传输。 这样， 可能会有多个传输点同时为终端进行数据传输的情况。
例如， 在载波聚合（Carrier Aggregation, CA ) 的场景下， 宏基站和微 基站的小区分别部署在不同的载波。 终端进入微基站的信号覆盖范围， 同时 终端也在宏基站的信号覆盖范围内， 这样宏基站和微基站两个基站就可以同 时为终端提供服务。 但是根据现有机制， 上行控制信息的传输开销和时延较 高。 发明内容

图 2为本申请另一实施例提供的上行控制信息处理方法的流程示意图， 如图 2所示。
201、终端接收第一传输点发送的指示信息，所述指示信息用以指示所述 第二传输点的上行控制信息在所述第二传输点的物理上行控制信道上传输。
202、所述终端根据所述指示信息，在所述第二传输点的物理上行控制信 道上发送所述第二传输点的上行控制信息。

为使得本申请实施例提供的方法更加清楚， 下面将以具有载波聚合特性 的 LTE系统作为举例。在具有 CA特性的 LTE系统中， 用户设备可以通过多 个小区与该多个小区所属的 eNodeB 进行通信。 其中， 一个小区是主小区 ( Primary Cell, PCell ) , 其他小区是辅小区 ( Secondary Cell, SCell ) 。 —般来说， UE的全部上行控制信息都是在主小区所属的 eNodeB的 PUCCH 上进行传输的。 当主小区所属的 eNodeB (即宏基站 eNodeB A )与辅小区所 属的 eNodeB (即微基站 eNodeB B ) 不为同一个 eNodeB时， UE则会将 eNodeB A的上行控制信息发送给 eNodeB A, 由 eNodeB A通过 eNodeB A 与 eNodeB B之间的路径 (即回程 backhaul )再传递给 eNodeB B, 这样， 导致了上行控制信息的传输开销的增加和传输时延的增加， 甚至传输时延会 超过一些上行控制信息的传输时延要求， 例如， ACK信息或 NACK信息的传 输时延要求。 eNodeB A具体可以在增加辅小区的流程中， 釆用本申请提供 的技术方案， 以指示 eNodeB B的上行控制信息在所述 eNodeB B的物理上 行控制信道上传输。 需要说明的是， 其中涉及的增加辅小区的概念， 可以理 解为增加一个小区作为辅小区， 可以根据现有技术实现， 在本申请中不做赘 述。
图 3为本申请另一实施例提供的上行控制信息处理方法的流程示意图， 如图 3所示。
301、 eNodeB A 为 UE 确定待增加的辅小区， 以及该辅小区所属的 eNodeB B。
具体地， eNodeB A具体可以根据 UE上报的测量结果， 例如， A4测量 事件，决定将所述 A4测量事件所指示的邻区增加为所述 UE的辅小区。其中， A4测量事件是邻区信号强度高于一个阈值（ A4的定义具体请参见 3GPP TS 36.331 )。 其中， 基站具体则可以根据网络部署， 例如， 参考信号接收功率 ( Reference Signal Received Power , RSRP ) 或参考信号接收质量 ( Reference Signal Received Quality, RSRQ )等参数获取该阈值。 然后， eNodeB A则可以才艮据所述辅小区的小区标识，确定该辅小区所属的 eNodeB B。
302、 eNodeB A向 eNodeB B发送请求消息， 该请求消息用于请求配置 所述辅小区， 所述请求消息中包含第一指示信息， 所述第一指示信息用以指 示所述 eNodeB B的上行控制信息在所述 eNodeB B的 PUCCH上传输。
例如， 所述第一指示信息可以为直接的指示信息， 用以直接指示所述第 二传输点的上行控制信息在所述第二传输点的物理上行控制信道上传输。 其 中， 所述直接的指示信息可以为所述第二传输点的上行控制信息与所述第二 传输点的物理上行控制信道的关联关系。
