Description

在载波聚合中上行数据的调度方法和装置 Method and device for scheduling uplink data in carrier aggregation

技术领域 Technical field

本发明属于通信领域，尤其涉及在载波聚合中上行数据的调度方法和装置。背景技术 The present invention belongs to the field of communications, and in particular, to a method and apparatus for scheduling uplink data in carrier aggregation. Background technique

长期演进***（ Long Term Evolution 筒称 LTE )需要在低移动性下峰值速率达到 IGbit/s, 高移动性下峰值速率达到 100Mbit/s。为了支持这样的峰值速率，需要更大的带宽，而更大带宽的频谱很难找到。为了高峰值速率和每个小区的平均吞吐量，需要更宽的带宽。现有技术中，第三代合作伙伴项目提出了载波聚合技术，来满足更大带宽的需求。截止到 LTE协议 Rel-11版本，只支持同基站下的 CA(intra-eNB CA),即主小区和辅小区属于相同的基站。未来，为了对热点区域提供更好的覆盖，很可能会采用基站间的 CA(inter-eNB CA) 部署，即实现 MSA (多流聚合）。在这种部署场景下， pico (小站点）用来和 macro (宏基站）协同为 UE提供服务， macro下的 Pcell (主服务小区）提供广覆盖， Pico下的 Scdl (辅服务小区）用来进行热点区域的数据增强， Pico 更多承担用户面的业务数据传输， macro则负责传输控制信令。 Pico可能承担部分或全部的用户数据业务，实现控制面 /数据面分离（CP/UP分离）。 Pico 包含但不限于 HeNB ( Home eNB , 家庭基站）、 RRH ( Radio remote head, 射频拉远 ) 、 NCT小区（ New Carrier Type )基站等。 The Long Term Evolution (LTE) requires a peak rate of IGbit/s at low mobility and a peak rate of 100 Mbit/s at high mobility. To support such peak rates, more bandwidth is needed, and a larger bandwidth spectrum is hard to find. For high peak rates and average throughput per cell, a wider bandwidth is required. In the prior art, the third generation partner project proposed carrier aggregation technology to meet the needs of greater bandwidth. As of the Rel-11 version of the LTE protocol, only the CA (intra-eNB CA) under the same base station is supported, that is, the primary cell and the secondary cell belong to the same base station. In the future, in order to provide better coverage for hotspots, it is likely to use inter-base station CA (inter-eNB CA) deployment, which is to achieve MSA (multi-stream aggregation). In this deployment scenario, pico (small site) is used to cooperate with the macro (macro base station) to provide services for the UE, and the Pcell (primary serving cell) under the macro provides wide coverage, and the Scdl (secondary serving cell) under the Pico is used. For data enhancement in hotspot areas, Pico is responsible for the transmission of business data on the user side, and macro is responsible for transmitting control signaling. Pico may be responsible for some or all of the user data services, enabling control plane/data plane separation (CP/UP separation). Pico includes but is not limited to HeNB (Home eNB, Home Base Station), RRH (Radio Remote Head), NCT Cell (New Carrier Type) base station, and the like.

在现有的载波聚合技术中，当用户设备需要进行上行数据发送时，由于只有宏基站配置了物理上行控制信道，所以只能通过宏基站配置的物理上行链路 — — 控制信道将调度请求发送到所述宏基站，而宏基站在接收到所述调度请求后，并不能分辨出触发所述上行数据发送的基站是自身还是小基站，上行数据会全部发送到所述宏基站，宏基站再根据预先设定的分配策略，将部分上行数据发送到小基站。如果触发上行数据发送的为小基站，则会造成网络负载增加以及信号路损增加。发明内容 In the existing carrier aggregation technology, when the user equipment needs to perform uplink data transmission, since only the macro base station configures the physical uplink control channel, only the physical uplink configured by the macro base station can be configured. The control channel sends a scheduling request to the macro base station, and after receiving the scheduling request, the macro base station cannot distinguish whether the base station that triggered the uplink data transmission is itself or a small base station, and the uplink data is all sent to The macro base station and the macro base station further transmit part of the uplink data to the small base station according to a preset allocation policy. If the small data base that triggers the uplink data transmission is triggered, the network load increases and the signal path loss increases. Summary of the invention
