It referring to fig. 2, is that the embodiment of the present invention provides a kind of schematic flow diagram of data transmission method, side as shown in Figure 2 Method may include that step is implemented as follows:
Step S201, base station determines the first PRB binding ginseng according to system bandwidth, for the transmission bandwidth of user equipment (UE) distribution Number.
According to the specification of 3GPP, it is together united that the pilot resource element in different PRB can bind (bundling) Channel estimation is executed, to improve the quality of channel estimation.Multiple (2 or more) are if neighbouring PRB has correlation, example Such as, it is scheduled to the same user equipment (UE), then identical pre-coding matrix can be used in multiple neighbouring PRB, to join Share the data channel for carrying out estimated data resource element, herein neighbouring can refer between PRB particular range (such as: it is special Fixed distance range) in, which can be rationally arranged by those skilled in the art according to specific communication system.
In some embodiments, base station can be bound according to Physical Resource Block (Physical Resource Block, PRB) Configuration information, system bandwidth and the transmission bandwidth for UE distribution determine that the first PRB binds parameter.The PRB binding configuration information Including the mapping relations between the system bandwidth, the transmission bandwidth and the first PRB binding parameter.Here PRB is tied up Determine configuration information and can be in agreement to provide, base station and UE, which default, to be known；It can also be base station to be supported according to system bandwidth and UE The business datum amount configuration of transmission, the PRB binding configuration information of configuration can be sent to the UE by the base station at this time, so as to The UE knows the first PRB binding parameter, and for details, reference can be made to be detailed below.
In some embodiments, the first PRB binding parameter is alternatively referred to as benchmark PRB binding parameter, the first PRB Binding parameter can be used for indicating the size of PRB binding, that is, mark is bound to resource block (Resource Block, RB) together Number.In some embodiments, the continuous RB that quantity can be met to the first PRB binding parameter is known as a RB group. The first PRB binding parameter can also be used in when data are transmitted to the transmission data carried in same RB group using same (i.e. identical) pre-coding matrix carries out precoding.
The transmission bandwidth can refer to that base station is the uplink bandwidth or downstream transmission bandwidth of UE distribution, this Inventive embodiments are without limitation.The transmission bandwidth also can refer to scheduling resource (the i.e. scheduling band that the base station is UE distribution Width dispatches frequency domain resource).
Step S202, information is assessed according to the up channel of the UE in the described base station, and determination is corresponding with the transmission bandwidth Incrementation parameter.
In some embodiments, the up channel assessment information can include but is not limited to last channel detection reference Signal (Sounding Reference Signal, SRS) channel assessment information, last demodulated reference signal (De Modulation Reference Signal, DM-RS) channel assessment information etc., or institute is detected using other reference signals The assessment information of channel quality corresponding to transmission bandwidth is stated, the embodiment of the present invention is without limitation.
In some embodiments, last SRS channel assessment information can refer to last or the last time in system band When transmitting data in width, the corresponding channel quality of the system bandwidth estimated using SRS.
In TDD system, the base station can be passed through upper using the reciprocity (i.e. symmetry) of uplink and downlink channel The estimation of row channel to obtain the estimation of down channel indirectly.It that is to say, heretofore described base station can be fed back by the UE Up channel assess information, come determine down channel assess information.
In some embodiments, since a current base station and UE do not have started in the system bandwidth or transmission bandwidth Data are transmitted, are not known when previous uplink/downlink channel assessment information.Therefore the base station can refer to described in the last time The up channel of UE feedback assesses parameter (such as last time SRS channel assessment information) to determine the corresponding increment of the transmission bandwidth Parameter, i.e., the described base station bind parameter in view of the channel quality or channel condition of the transmission bandwidth to adjust PRB, obtain institute State corresponding increment PRB binding parameter (the i.e. described incrementation parameter) of transmission bandwidth.
In some embodiments, the transmission bandwidth is the fractional bandwidth in the system bandwidth or whole bandwidth.It is described Transmission bandwidth can indicate in the form of granularity is PRB, such as transmission bandwidth is 1800KHz, is represented by 10PRB, i.e. 10*12* 15KHz=1800KHz.
Step S203, parameter and the incrementation parameter are bound according to the first PRB in the described base station, determine that the 2nd PRB is tied up Determine parameter；Wherein, the 2nd PRB binding parameter is used for each RB at least one the RB group for including to the transmission bandwidth Transmission data in group carry out precoding using each corresponding pre-coding matrix of RB group, and the RB group includes quantity Meet the continuous RB of the 2nd PRB binding parameter.
In some embodiments, the 2nd PRB binding parameter can be used for indicating the size of PRB binding, i.e. mark binding The number of RB together.The 2nd PRB binding parameter can also be used in the one or more for including in the transmission bandwidth The transmission data in each RB group in RB group carry out precoding using each corresponding pre-coding matrix of RB group.One The corresponding pre-coding matrix of a RB group, a pre-coding matrix can correspond to one or more RB groups.Namely it is different RB group In transmission data same or different pre-coding matrix can be used carry out precoding, the embodiment of the present invention is without limitation.But Transmission data in same RB group need to carry out precoding using identical/same pre-coding matrix.Here transmission data can be with Including upstream data or downlink data.
For example, for example, base station be UE distribution downstream transmission bandwidth be 20PRB, determine the 2nd PRB bind parameter For 5PRB, then when reality sends downlink data to the UE by the downstream transmission bandwidth, the base station can for the base station Continuous 5 resource block RB are bound together according to using 5PRB as granularity, form a RB group.Correspondingly, each data pass When defeated, the quantity that the downstream transmission bandwidth can carry the RB group of transmission is 4, i.e. 20/5=4.The line number under the actual transmissions of base station According to when, the base station can using 4 pre-coding matrixes respectively in this 4 RB groups downlink data carry out precoding, will be pre- Downlink data after coding is sent to UE.
In addition, the 2nd PRB binding parameter is greater than the first PRB binding ginseng when the incrementation parameter is positive number Number, then when transmitting the data of same data volume size, the RB group quantity for being bound formation is less, and precoding number is less, simultaneously Also reduce the complexity of transmitting terminal precoding processing.Such as quoting above-mentioned example, it is assumed that it is 2PRB that the first PRB, which binds parameter, It is then granularity according to 2PRB, the quantity that the downstream transmission bandwidth can carry the RB group of transmission is 10, i.e. 20/2=10.Accordingly Ground, in actual transmissions data, if need to be carried out using 10 pre-coding matrixes according to original the first PRB binding parameter 2PRB 10 precodings；However the 2nd PRB adjusted binding parameter 5PRB is used using 4 pre-coding matrixes need to prelist for 4 times Code, hence it is evident that reduce the complexity of transmitting terminal precoding processing.
Step S204, the described base station sends instruction information to the UE, and the instruction information is for described in UE determination 2nd PRB binds parameter, and the instruction information includes the transmission bandwidth and the incrementation parameter, or including the transmission belt Wide and described 2nd PRB binds parameter.Correspondingly, the UE receives the instruction information.
The base station can send instruction information to the UE, and the instruction information determines the 2nd PRB for the UE Bind parameter.The instruction information may include the transmission bandwidth and the incrementation parameter or the instruction information may include The transmission bandwidth and the 2nd PRB bind parameter.
In some embodiments, the instruction information may particularly include the index of the transmission bandwidth (the i.e. described UE can Dispatch the running time-frequency resource that uses, such as 20PRB), the index (such as numerical value " 2 ") of the incrementation parameter or the 2nd PRB binding The index (such as numerical value " 5 ") of parameter, optionally, the instruction information may also include the tune that the base station is UE distribution The information such as system/demodulation mode, the embodiment of the present invention is without limitation.
In some embodiments, the instruction information can be carried on Downlink Control Information (Downlink Control Information, DCI) instruction and/or wireless heterogeneous networks (Radio Resource Control, RRC) instruction in, so as to The instruction information is sent to the UE by the base station.
Before step S201, the base station can support transmission according to UE in the system bandwidth and serving cell of the base station Business data volume, the system bandwidth is divided at least one scheduling bandwidth, and be at least one described scheduling bandwidth In each self-configuring of each scheduling bandwidth corresponding benchmark PRB binding parameter (i.e. the first PRB binds parameter).
If the UE supports the data volume of the business of transmission more, the scheduling bandwidth divided is larger, the tune The number for spending bandwidth is less.Correspondingly, if the UE supports the data volume of the business of transmission less, the scheduling divided Bandwidth is smaller, and the number of the scheduling bandwidth is more.The scheduling bandwidth, which can refer to, can support to dispatch when the UE transmission services/ The range of the data bandwidth of occupancy, such as 0-20PRB.The base station can configure corresponding benchmark PRB for each scheduling bandwidth and tie up Determine parameter (i.e. the first PRB bind parameter), the benchmark PRB binding parameter that configures here can be to be provided in agreement, can also It is base station side oneself configuration, the embodiment of the present invention is without limitation.
For example, a kind of table including PRB binding configuration information is provided referring to such as the following table 1.
Table 1
Table 1 shows base station cell when establishing, and base station is schedulable according to bandwidth of cell (i.e. system bandwidth) and user equipment Bandwidth range (i.e. scheduling bandwidth) is that each scheduling bandwidth configures corresponding benchmark PRB binding parameter, i.e. the first PRB binding ginseng Number.Can table 1 it is found that for same system bandwidth, different scheduling bandwidths corresponds to different the first PRB binding parameters.
In step s 201, the base station in the system bandwidth for learning the base station and is the transmission bandwidth of UE distribution Afterwards, the base station can be determined and the transmission according to PRB binding configuration information, the system bandwidth and the transmission bandwidth Corresponding first PRB of bandwidth binds parameter.For example, the PRB binding configuration information shown in reference list 1, it is assumed that the system band of base station Width is 10Mhz, be UE distribution transmission bandwidth be 20PRB, since 20PRB is located at 10~30PRB range, it is determined that out with it is described The corresponding first PRB binding parameter of transmission bandwidth is 3PRB.
In some embodiments, the PRB binding configuration information may include the system bandwidth, the scheduling bandwidth (such as The transmission bandwidth) and the first PRB binding parameter between mapping relations.
In some embodiments, every PRB or RB refers to a time/frequency source block.An every PRB or every RB, in the time domain It may include 7 symbols (symbol), may include 12 subcarriers on frequency domain, each subcarrier or subcarrier spacing are 15Khz.
In some embodiments, the transmission bandwidth or system bandwidth may include multiple PRB, may include multiple on frequency domain Subcarrier.
In step S202, the base station can assess information (such as last time SRS channel estimating according to the up channel of the UE Information), the corresponding destination channel running parameter M of the transmission bandwidth is calculated, is then determined according to the object variations parameter M Corresponding incrementation parameter out.
Change specifically, the base station can be calculated using following calculation formula to the corresponding destination channel of the transmission bandwidth Parameter M:

Wherein, HSRS,iIt indicates the up channel assessment information on i-th of subcarrier, such as can specifically indicate i-th of subcarrier On last SRS channel assessment information etc..HSRS,i+LIndicate that the up channel on the i-th+L subcarriers assesses information.I-th Subcarrier and the i-th+L subcarriers are the subcarrier on the transmission bandwidth, and i and L are natural number, M0Indicate i-th of son The channel variation parameter of band channels corresponding to carrier wave to the i-th+L subcarriers.
L PRB binding parameter threshold corresponding with the system bandwidth is related.The corresponding PRB binding ginseng of the system bandwidth Number threshold value can be specified in agreement, can also be base station side configuration, the embodiment of the present invention is not construed as limiting.
For example, if system bandwidth is 10MHz, the corresponding PRB binding parameter upper-lower door of 10MHz is defined in agreement Limit value (i.e. threshold interval) is respectively 2PRB and 6PRB, then L is the number for the subcarrier that j PRB pair is answered, and wherein j is more than or equal to 2, and it is less than or equal to 6, and j is integer.It is optional that j can be base station side, if j is 3, L 36, i.e. 3*12=36. Assuming that L value is 3PRB (i.e. L=36) by the base station, calculated using above-mentioned formula (1) less than normal (i.e. lower than default threshold to A value Value, such as 0.1), then L value can be also that 4PRB, 5PRB or 6PRB recalculate to obtain new A value, this hair by the base station Bright embodiment is without limitation.
