Further, when the quantity of base station is at least two, the mark of at least two carrier waves is sent to terminal by the master base station at least two base stations.Wherein, master base station is to establish the base station communicated with terminal at first.
Specifically, the mark of at least two carrier waves can carry in the message of communications protocol layers, the communications protocol layers are physical layer, medium access control (Media Access Control, abbreviation MAC) layer, Packet Data Convergence Protocol (Packet Data Convergence Protocol, abbreviation PDCP) layer, wireless spread-spectrum technology (Radio Link Control, abbreviation RLC) layer and wireless heterogeneous networks (Radio Resource Control, one of abbreviation RRC) layer, to realize the transmission of the mark of at least two carrier waves.
Step 302: base station sends the data of terminal device at least two carrier waves.
In the present embodiment, the data of terminal device include data information and control information.
In practical applications, it is sent after being handled by the data that physical layer receiving mac layer issues.MAC layer can be issued with the one-to-one data of at least two carrier waves to physical layer to physical layer, and a data can also be only issued to physical layer.When MAC layer is issued with the one-to-one data of at least two carrier waves to physical layer to physical layer, physical layer respectively can successively be handled as follows each part data: increase cyclic redundancy check code (Cyclic Redundancy Check, abbreviation CRC), segmentation, channel coding, rate-matched, modulation, scrambling, antenna mapping.When MAC layer only issues a data to physical layer, the number of data can be copied into equal with the quantity of at least two carrier waves by physical layer, and then each part data are successively handled as follows respectively: increase CRC, segmentation, channel coding, rate-matched, modulation, scrambling, antenna mapping；First this part of data can also successively be carried out with increase CRC, segmentation, the processing of channel coding, then the number of the data after channel coding is copied into equal with the quantity of at least two carrier waves, rate-matched, modulation, scrambling, the processing of antenna mapping is successively finally carried out to each part data again.
It should be noted that, when the channel coding method for carrying out channel coding use to each part data is identical, the unlimited redundancy versions for determining to use in rate-matched of the present embodiment are also identical, i.e., the redundancy versions for carrying out rate-matched use to each part data may be the same or different.
Step 303: terminal obtains the mark of at least two carrier waves.
As previously mentioned, at least one base station is obtaining resource allocation information by way of accessing the memory of itself, terminal is obtaining resource allocation information by way of receiving the resource allocation information of at least one base station transmission.
Step 304: the data of terminal receiving terminal apparatus at least two carrier waves.
In practical applications, if different modules, which is arranged, in terminal receives data on each carrier wave, then interface can be set between the module of carrier wave for receiving the identical data information of transferring content or control information, so that the identical data information of content and control information are merged decoding.
Step 305: terminal log evidence is decoded.
In a kind of implementation of the present embodiment, which may include:
The identical information of content received at least two carrier waves is merged, which is control information or data information；
Information after merging is decoded.
In practical applications, merge and refer to that the factor is combined according to a certain percentage by the bit stream carried at least two carrier waves.Since the bit stream transmitted on each carrier wave can contain certain information mistake
Amount, and the identical probability in position for the bit stream appearance mistake transmitted on each carrier wave is too low, therefore can be obtained after merging than merging preceding better performance, and decoded accuracy rate is higher at this time.
It should be noted that, it is that will be decoded after information superposition due to merging decoding, therefore the control information at least two carrier waves is merged decoding needs the position of running time-frequency resource of the foundation where controlling information identical, or the running time-frequency resource where control information position it is known on the basis of, be decoded to control after information is accurately superimposed.In addition, interface can be arranged between the module of the identical information of reception content if receiving end is arranged different modules and receives data on each carrier wave, so that the identical information of content is merged decoding.
Optionally, which can also include:
If the received information decoding failure at least two carrier waves, the identical information of reception content at least two carrier waves again；
It will again received on at least two carrier waves and received information merging at least two carrier waves before reception again；
Information after merging is decoded.
It is decoded into power using retransmitting to improve, in the case where not considering delay, it can be ensured that communication reliability.
In practical applications, terminal can send confirmation signal to base station after receiving and being successfully decoded to obtain data information；After receiving and data information is not successfully decoded out, it can be sent to base station and deny signal.If therefore base station does not receive the response signal (confirmation signal or denying signal) of terminal transmission within the set time, determines to control information decoding failure, retransmit control information；If receive terminal transmission within the set time denies signal, determines data information decoding failure, retransmit data information.
In another implementation of the present embodiment, which may include:
Received information on one carrier wave is decoded, which is control information or data information.
It is readily apparent that, does not on the one hand need to be modified existing decoding process, cost of implementation is low；On the other hand received information on other carrier waves is not decoded when received information successfully decoded on to a carrier wave, reduces blind examination process (for control information) and merging process.
Optionally, which can also include:
Fail if being decoded to information received on a carrier wave, the identical information of content received at least two carrier waves is merged, which is control information or data information；
Information after merging is decoded.
Preferably, which can also include:
If received information decoding failure, receives at least two carrier waves again at least two carrier waves
The identical information of content；
It will again received on at least two carrier waves and received information merging at least two carrier waves before reception again；
Information after merging is decoded.
