Abstract

Disclosed are a data transmission method and device, mainly comprising: determining downlink data scheduled by a downlink hybrid automatic repeat request (HARQ) process corresponding to the uplink feedback message sent by a terminal device based on a first cell device receiving an uplink feedback message sent by a second cell device, and according to the time information associated with the uplink feedback message and determined by the second cell device contained in the received uplink feedback message. As a result, for the uplink feedback message sent by the terminal device, the first cell device accurately determines the downlink data scheduled by the HARQ process corresponding to the uplink feedback message sent by the terminal device by receiving the time information associated with the uplink feedback message and determined by the second cell device and the time relationship with the second cell device, thus overcoming the difficulty in determining for which downlink data scheduled by the HARQ process the received uplink feedback message is fed back, and improving scheduling capability of the downlink data.

Description

Data transmission method and device
A kind of data transmission method and equipment technical field
The present invention relates to wireless communication technology field, more particularly to a kind of data transmission method and equipment.Background technology
With the development of mobile communication technology, user's request more and more higher.By introducing Microcell in existing grand net（That is Small Cell), the quantity of system cell is exponentially improved, in the case where each cell throughput keeps constant, exponentially lifting system capacity.Generally, formation Hetnet networks after Microcell are introduced in macrocell（Heterogeneous Network, heterogeneous network）.Wherein, microcell base station at least includes Home eNodeB, femtocell, Femto base stations, AP (Access Point, access point in Hetnet networks）, Pico femto base stations, Mico micro-base stations and LPN (Low Power Node, low power base station）Deng.
At present, the form of macrocell and the Microcell formation Hetnet network architectures includes but is not limited to following three kinds：
The first framework：Macrocell and Microcell share RNC (a Radio Network Controller, radio network controller）.
In this framework, Microcell is directly interacted by Iub interface with RNC.
Second of framework：The RNC for managing macrocell and the RNC for managing Microcell are separate.
In this framework, Microcell is connected with managing the RNC of the Microcell by Iub interface, and the RNC for managing Microcell is connected by existing Iur interfaces with managing the RNC of macrocell.
The third framework：Microcell is connected by Iuh interfaces or Iurh interfaces with the base-station gateway with aggregation feature, and is connected by the base-station gateway by Iur interfaces with managing the RNC of macrocell.
In this framework, the information exchange between Microcell and the RNC for managing macrocell is forwarded by base-station gateway.
In addition, to ensure to introduce HSDPA (High Speed Downlink Packet Access, high-speed slender body theory in heterogeneous network system capacity, R5 agreements）Technology, realizes downlink data high-speed transfer. But, soft handover can not be carried out using the terminal device of HSDPA technologies, and then by introducing MF (Mulit-Flow, multiple stream transmission）Technology.So, terminal device is when carrying out soft handover, and network side is given carries out data transmission using the terminal equipment configuration multilink of HSDPA technologies, and terminal device can obtain downlink data dispatching from multiple cellular links simultaneously.Wherein, to be that terminal device service is small divide into main serving cell（Serving HS-DSCH cell, the also referred to as main plot of terminal device or main serving cell）And auxiliary serving cell（Assisting serving HS-DSCH cell, also referred to as the assistant service cell of terminal device or assisted cell or assistance cell）；Terminal device sends uplink feedback data after the downlink data of multiple cells is obtained by the way of combined coding.Applying MP-HSDPA (Multipoint Processor, multipoint processor）After characteristic, improve the descending throughput performance of the terminal device using HSDPA technologies, while lifting network resource utilization.
However, in heterogeneous network system, when Microcell and macrocell, which are used, does not use multiple stream transmission technology with frequency cloth net mode and UE, i.e. UE can only receive downlink data from a cell.For in the Zone switched terminal device of grand Microsoft, now the serving cell of terminal device is macrocell, and Microcell is concentrated in UE activation, belongs to the non-service cell of terminal.But, because the path loss of the up-link between terminal device and Microcell is smaller, because power control Microcell can reduce the transmission power of terminal, cause macrocell can not receive the upward signal of the terminal, including the uplink feedback data of terminal, this, which allows for macrocell, can not receive the uplink feedback data of the terminal device.Current settling mode is the communication interface by being set up between macrocell and microcell base station so that the uplink feedback data of terminal device feedback passes through non-service cell（That is Microcell) it is transferred to serving cell（That is main plot）.
When Microcell and macrocell use alien frequencies cloth net mode, terminal device is retrieved as the downlink data that the main plot of its service and secondary cell are sent by above-mentioned MF modes, terminal device uses combined coding mode to main plot and secondary cell feeding back uplink feedback data, but working frequency points of the uplink feedback data of terminal device feedback only in main plot base station are sent, so that secondary cell base station can not receiving terminal apparatus feeds back directly in the working frequency points of itself uplink feedback data, it is necessary to transmit relevant information by communication interface between two cell base stations.
Either in common-frequency network, or in alien frequencies network, the propagation delay time of communication interface between macrocell and microcell base station, cause serving cell receive non-service cell transmission uplink feedback after/ Or secondary cell is after the uplink feedback information of main plot transmission is received, it is impossible to which it is the feedback for which downlink data to judge the uplink feedback information, influences the scheduling of downlink data.The content of the invention
