Step 102: for terminal distribution for feeding back the feedback resources of described first data block demodulation result, and be Described transmission data block distribution data transmission resources.
For enabling to the terminal feedback demodulation result to the first data block, in the present embodiment, base station needs for eventually The feedback resources (such as ACK/NACK resource) that end distribution is corresponding, in order to will transmission data block such as industry Business transmission of data blocks is to terminal, and in the present embodiment, base station also needs to as transmission data block distribution data transmission resources.
In view of the feedback resources making terminal can obtain correspondence after to the first data block demodulation, this enforcement First example method can determine the position of feedback resources, is determined by the position of suitable feedback resources, permissible Terminal is made to obtain corresponding feedback resources after to the first data block demodulation in time；Therefore, the present embodiment Described in for terminal distribution for the described terminal process to the feedback resources of described first data block demodulation result May include that
Determine the described terminal position to the feedback resources of described first data block demodulation result；
It is feedback resources described in described terminal distribution according to defined location.
Preferentially, this example determining, described terminal is to the feedback resources of described first data block demodulation result The process of position may include that

Specifically, base station, can be according to reception after the detectable signal receiving terminal transmission or access signal Propagation delay between the detectable signal or access Signal estimation base station and the terminal that arrive；Base station can also receive end The demodulation process ability of the terminal log evidence that end reports.The demodulation process ability bag of terminal to report in the present embodiment Include: terminal demodulates demodulation overhead time and the demodulation result group bag (such as ACK/NACK group bag) of the first data block Time overhead.
In actual applications, the propagation delay being in connected state terminal, terminal to report demodulation process are known in base station Ability, base station demodulation process based on propagation delay and terminal ability determine reference data bag complete demodulation time Between, it is that it distributes the resource location for transmitting reference data bag corresponding A CK/NACK according to this time, as Shown in Fig. 2, base station receives the demodulation ability grade of terminal feedback, signal that base station sends or letter according to terminal Road determines the propagation delay of base station and terminal room, and base station demodulation ability based on terminal feedback grade determines (to be estimated Calculate) terminal demodulates the first data block required time, and base station demodulates the first data block according to propagation delay and terminal Required time determines the preferred opportunity of terminal to report the first data block demodulation result, is used for for terminal distribution accordingly The resource of feedback；In fig. 2 business datum schedule information (i.e. the instruction information of data transmission resources) and The instruction information of feedback resources is all carried on high frequency carrier.
Step 103: by described data transmission resources successively by described first data block in a scheduling unit It is sent to described terminal with described second data block.
Specifically, when data transmission resources is positioned at high band carrier wave, according to described data transmission resources pair Transmission data block is sent to described terminal by the high frequency carrier answered.
Specifically, in the present embodiment, in a scheduling unit, data block transmission timing is: first send out the first data Then block is sending the second data block.
Preferentially, scheduling unit described in the present embodiment is 1 subframe or micro-frame or several symbols in time Number persistent period, frequency domain is the integral multiple of a subcarrier.
In order to make terminal know this transmission data block be divided into the first data in the present embodiment method Block and the second data block, it is to avoid terminal uses traditional feedback mechanisms to carry out feedback demodulation result；In step 101 and Between step 103, also include: notify described in described terminal transmit data block be divided into the first data block and Second data block.
Such as by broadcast, control channel, high-level signaling or can come by described terminal by the way of agreement Described transmission data block is divided into the first data block and the second data block.
The broadcast of the present embodiment can be carried on low-frequency range carrier wave (the most traditional 3G, 4G carrier wave), or It is carried on high band carrier wave.
It addition, the present embodiment can also be between step 101 and step 103, it is also possible to including: notice institute State terminal when the first data block demodulation failure, the data transmission mechanism of base station side or strategy；Such as when During one data block demodulation failure, resume defeated subsequent data blocks at this scheduling unit relaying, dispatch at the next one Described transmission data block is retransmitted by unit.Specifically, can be by broadcast, control channel, high-rise letter Order or agreement mode notify described terminal when the first data demodulate unsuccessfully, the data-set of side of standing System or strategy.
In the present embodiment, for terminal can be made to may determine that the first data block demodulation failure or success, Mode except above-mentioned employing CRC, it is also possible to by the way of repeating to send the first data block Make terminal may determine that the first data and demodulate unsuccessfully or success, end side, first to multiple repetitions Data block is demodulated, and then contrast demodulation result judges whether to demodulate successfully or failure.
Step 104: receive the demodulation to described first data block that described terminal is fed back by described feedback resources Result.
After the first data block is demodulated by terminal, the feedback resources distributed by base station feeds back the first data The demodulation result (success or failure are i.e. represented by transmission ACK/NACK and demodulate successfully or failure) of block. The present embodiment method can receive during sending transmission data block terminal feedback to the first data block Demodulation result；Such as base station is first sent out the first data block and is sent out the second data block the most again, is sending the first data During sending the second data block after block, the demodulation to the first data block of terminal feedback will be received Result；
