Description

Data transmission method and device

The present invention relates to the field of wireless communication technologies, and in particular, to a data transmission method and device. Background technique

With the development of mobile communication technology, user demand is getting higher and higher. By introducing a micro cell (i.e., Small Cell) into the existing macro network, the number of system cells is doubled, and the system capacity is doubled while the throughput of each cell remains unchanged. Generally, a Hetnet network (heterogeneous network) is formed after the micro cell is introduced in the macro cell. The micro cell base station in the Hetnet network includes at least a home base station, a femto cell base station, a Femto base station, an AP (Access Point, an access point), a Pico pico base station, a Mico micro base station, and an LPN (Low Power Node). Wait.

Currently, macro cells and micro cells form the Hetnet network architecture, including but not limited to the following three types:

The first architecture: The macro cell and the micro cell share a RNC (Radio Network Controller).

In this architecture, the microcell interacts with the RNC directly through the Iub interface.

The second architecture: The RNC that manages the macro cell is independent of the RNC that manages the micro cell.

In this architecture, the micro cell and the RNC managing the micro cell are connected through the Iub interface, and the RNC managing the micro cell is connected to the RNC managing the macro cell through the existing Iur interface.

The third architecture: The micro cell is connected to the base station gateway with the aggregation function through the Iuh interface or the Iurh interface, and the base station gateway is connected to the RNC managing the macro cell through the Iur interface.

In this architecture, the information exchange between the microcell and the RNC managing the macrocell is forwarded by the base station gateway.

In addition, in order to ensure the capacity of the heterogeneous network system, HSDPA (High Speed Downlink Packet Access) technology is introduced into the R5 protocol to realize high-speed downlink data transmission. However, the terminal equipment using the HSDPA technology cannot perform soft handover, and is further introduced by the MF (Mulplex-Flow) technology. In this way, when the terminal device performs the soft handover, the network side configures multiple links for the terminal device that uses the HSDPA technology to perform data transmission, and the terminal device can obtain downlink data scheduling from multiple cell links at the same time. The serving cell for the terminal device is divided into a primary serving cell (Serving HS-DSCH cell, also referred to as a primary cell or a primary serving cell of the terminal device) and an Assisting serving HS-DSCH cell (also referred to as a terminal device). The auxiliary serving cell or the auxiliary cell or the assisting cell); after acquiring the downlink data of the multiple cells, the terminal device sends the uplink feedback data by using the joint coding manner. After the application of the MP-HSDPA (Multipoint Processor) feature, the downlink throughput performance of the terminal device adopting the HSDPA technology is improved, and the network resource utilization rate is improved.

However, in a heterogeneous network system, when the micro cell and the macro cell adopt the same-frequency network deployment mode, and the UE does not adopt the multi-stream transmission technology, the UE can only receive downlink data from one cell. For the terminal device in the macro-soft handover area, the serving cell of the terminal device is the macro cell, and the micro cell belongs to the non-serving cell of the terminal in the active set of the UE. However, since the path loss of the uplink between the terminal device and the micro cell is small, the macro cell can reduce the uplink power of the terminal, and the macro cell cannot receive the uplink signal of the terminal, including the uplink feedback data of the terminal. This makes the macro cell unable to receive the uplink feedback data of the terminal device. The current solution is that the uplink feedback data fed back by the terminal device is transmitted to the serving cell (ie, the primary cell) through the non-serving cell (ie, the micro cell) through the communication interface established between the macro cell and the micro cell base station.

When the micro cell and the macro cell use the inter-frequency network, the terminal device obtains the downlink data sent by the primary cell and the secondary cell served by the terminal device by using the MF mode, and the terminal device uses the joint coding mode to feed back the uplink feedback data to the primary cell and the secondary cell. However, the uplink feedback data fed back by the terminal device is only sent at the working frequency of the primary cell base station, so that the secondary cell base station cannot directly receive the uplink feedback data fed back by the terminal device at its own working frequency point, and needs to pass between the two cell base stations. The communication interface conveys relevant information.

Whether in the same-frequency network or in the inter-frequency network, the transmission delay of the communication interface between the macro cell and the micro cell base station causes the serving cell to receive the uplink feedback sent by the non-serving cell/ After receiving the uplink feedback information sent by the primary cell, the secondary cell cannot determine the downlink data feedback for the downlink data, and affect the scheduling of the downlink data.

Among them, HSDPA technology adopts HARQ scheduling mechanism.

As shown in Figure 2, it is the schematic diagram of the HARQ scheduling mechanism. The so-called HARQ scheduling mechanism is that the network side schedules downlink data of a terminal device in a certain HARQ process, and receives uplink feedback information sent by the terminal device. The uplink feedback information includes HS-DPCCH (High Speed Dedicated Physical Control Channel). Physical control channel), HARQ-ACK (Hybrid-ARQ Acknowledgement hybrid automatic repeat request acknowledgement) (wherein the HARQ-ACK indicates whether a downlink data terminal device scheduled by a certain HARQ process is correctly received), PCK Precoding Control Indication, Encoding control indication) (where PCI is only used when configuring MIMO (Multiple Input Multiple Output) mode).

Since the network side adopts asynchronous HARQ for the downlink data transmission, and establishes a strict timing relationship between the downlink data transmission channel and the uplink data transmission channel, the network side can infer that the uplink feedback message is based on the time of the received uplink feedback message. Which HARQ process is scheduled for. In the HSDPA scheduling, each TTI (Transmission Time Interval) is 2 ms, and the HS-SCCH (High Speed Shared Channel) is used for the network side to carry the demodulation HS-PDSCH (High Speed Physical). Downlink Shared Channel, the modulation mode of the high-speed physical downlink shared channel, and the identifier of the terminal device are also used by the terminal device to determine whether the information sent on the HS-PDSCH is sent to itself and how to demodulate the channel.

In another embodiment of the present invention, when the network side decides to schedule a certain UE, the network first transmits related information of scheduling downlink data on the HS-SCCH channel, and after transmitting the HS-SCCH, is greater than 15.5slot. (slot) (ie, 2+3+7.5+3 as shown in FIG. 2) receives the uplink feedback information of the UE, and the network side determines the timing relationship between the downlink data transmission channel and the uplink data transmission channel.

The system frame number (SF) is the basic concept of system time in the cell, where SF adds a count value every 10ms, ranging from 0 to 4095.
