It is a kind of schematic flow diagram of retransfer scheduling method provided in an embodiment of the present invention referring to Fig. 1, as shown, should Method can include:

101, base station determines the re-transmission data for needing to retransmit；

Above-mentioned re-transmission data can be the re-transmission data that above-mentioned base station is retransmitted to terminal, be also possible to above-mentioned base station instruction The re-transmission data that above-mentioned terminal is retransmitted to above-mentioned base station.

102, above-mentioned base station generates control information according to above-mentioned re-transmission data, and above-mentioned control information includes resource instruction letter Breath, above-mentioned resource indication information indicate the target sub-band that above-mentioned re-transmission data occupy and above-mentioned re-transmission data in above-mentioned target The resource block group RBG occupied in subband；

Above-mentioned resource indication information can indicate the target sub-band that the re-transmission data that above-mentioned base station retransmits to terminal occupy with And the RBG occupied in above-mentioned target sub-band；It can also indicate that the target that the re-transmission data that terminal needs to retransmit to base station occupy Subband and the RBG occupied in above-mentioned target sub-band.

In an optional implementation manner, above-mentioned re-transmission data are the re-transmission number that above-mentioned base station is retransmitted to above-mentioned terminal According to above-mentioned resource indication information includes the first field and the second field, and above-mentioned first field is used to indicate above-mentioned re-transmission data and accounts for Above-mentioned target sub-band, above-mentioned second field are used to indicate the RBG that above-mentioned re-transmission data occupy in above-mentioned target sub-band.

Above-mentioned re-transmission data can be the re-transmission data that above-mentioned base station is sent according to the feedback information from above-mentioned terminal. For example, terminal sends feedback information to base station, which indicates the CBG that the base station needs to retransmit；The base station according to The feedback information is sent to the terminal retransmits data, which includes the CBG retransmitted.Referring to Fig. 2, Fig. 2 is the knot of TB Structure schematic diagram, as shown in Fig. 2, may include 5 CBG in a TB, according to position arrangement be respectively CBG0, CBG1, CBG2, CBG3, CBG4, i.e. first CBG to the 5th CBG, each CBG can be located at the position in TB according to it and distinguish.Again For example, it after terminal is decoded the first data from base station, determines in the object transmission block TB in first data First CBG and third CBG decoding failure；The terminal sends feedback information to the base station, which indicates the base Stand first CBG and third CBG retransmitted in target TB；Base station is sent to the terminal comprising being somebody's turn to do according to the feedback information The re-transmission data of first CBG and third CBG in target TB.

It can indicate to retransmit the subband that data occupy by the way of bitmap (bitmap).Above-mentioned first field can be with Occupy at least one bit in above-mentioned control information.Such as first field can occupy control information on it is continuous 4 ratio Special position.The system bandwidth in homologous ray and number of sub-bands may be not different.For example, system bandwidth 20MHz includes 4 The subband of 5MHz, i.e. subband 0, subband 1, subband 2, subband 3 can indicate this 4 subbands, i.e. 4 bits with 4 bits Position successively indicates subband 0, subband 1, subband 2, subband 3 according to sequencing, when the CBG of re-transmission occupies the first two subband, the One field is 1100.Again for example, system bandwidth 60MHz, the subband comprising 6 10MHz, i.e. subband 0, subband 1, son Band 2, subband 3, subband 4, subband 5 can indicate this 6 subbands with 6 bits, i.e. 6 bits according to sequencing according to Secondary expression subband 0, subband 1, subband 2, subband 3, subband 4, subband 5, when the CBG of re-transmission occupies subband 2, subband 4, first Field is 001010.The subband that the CBG retransmitted is occupied can be accurately indicated by the first field, the bit of occupancy is few, with The CBG of re-transmission is rapidly received convenient for terminal.

It is also possible to indicate to retransmit the RBG that data occupy in subband by the way of bitmap.Above-mentioned second field At least two bits in above-mentioned control information can be occupied.Such as continuous 15 bits.One in not homologous ray Physical Resource Block that resource block group (Resource Block Group, RBG) includes (Physical Resource Block, PRB quantity) is different, such as a RBG may include 4 PRB, also may include 5 PRB.Above-mentioned second field can The RBG occupied in above-mentioned target sub-band with the CBG retransmitted by multiple continuous bit instructions.For example, base station connects It after the feedback information for receiving terminal transmission, is retransmitted as unit of CBG, is that CBG0 and CBG3 is distributed in first subband RBG0-RBG5, the second field are 111111000000000, and the CBG that second field instruction retransmits is occupied in first subband RBG0-RBG5；The bit of second field can be corresponding with the RBG in subband；The front portion bit of second field Position can be corresponding with the RBG in the first subband, and rear portion bit can be some invalid bits.Citing comes again It says, after base station receives the feedback information of terminal transmission, is retransmitted as unit of CBG, before CBG0, CBG1, CBG4 distribution RBG0-RBG14 in three subbands, the second field are 111111111111111000, the CBG that second field instruction retransmits Occupy the RBG0-RBG14 in first three subband；RBG in the bit of second field and the target sub-band of the first field instruction Corresponding, the number for the bit that the second field occupies can be greater than or equal to the subband that the CBG retransmitted is occupied and be included The quantity of RBG, it is assumed that include 6 RBG in each subband, 6 most preceding bits can indicate 6 RBG in the first subband Occupancy situation, 6 intermediate bits can indicate the occupancy situation of 6 RBG in the second subband, 6 last bits Position can indicate the occupancy situation of 6 RBG in third subband.If in each subband including 5 RBG, the second field In 111111111111111000, first 15 indicate that retransmitting data occupies the first subband to third subband for 1 bit RBG0-RBG14, latter three can be invalid for 0 bit.

That is, the second field can occupy more bit in the case where controlling the enough situations of resource, at this time Two fields can carry out the instruction of full bandwidth.For example, full bandwidth includes 6 re-transmission subbands, each re-transmission subband includes 5 RBG, in order to carry out the instruction of full bandwidth, then the second field at least needs 30 bits, the corresponding instruction one of every 5 bits RBG resource in a re-transmission subband.In this case, the first field then can be omitted.

However, in the case where controlling resource anxiety, possibly resource that can not be more to the second field distribution.Meanwhile weight Pass the re-transmission subband that data tend not to occupy full bandwidth, can only occupy it is part of retransmit subband, the second field can be at this time Occupy the RBG occupation condition that less bit only indicates the re-transmission subband of the first field instruction.For example, full bandwidth packet 6 re-transmission subbands are included, each re-transmission subband includes 5 RBG, and the second field can occupy 15 bits, wherein if the first word The subband that section instruction retransmits is subband 1, subband 2 and subband 3, then RBG is accounted in the 1-5 bit indication subband 1 in the second field With situation, RBG occupancy situation in the 6-10 bit indication subband 2, RBG occupies feelings in the 11-15 bit indication subband 3 Condition.If the subband that the instruction of the first field retransmits is subband 1, subband 3 and subband 4, the 1-5 bit indication in the second field RBG occupancy situation in subband 1, RBG occupancy situation in the 6-10 bit indication subband 3, the 11-15 bit indication subband 4 Middle RBG occupancy situation.In this way, can occupy less control resource overhead by the combination of the first field and the second field and reach To the purpose of accurate instruction retransfer scheduling resource.

In the embodiment of the present invention, can resource that accurately instruction terminal re-transmission data to be received occupy, control resource Expense it is few.
