Fig. 1 is the schematic flow sheet of the embodiment of data transmission method one of the present invention.
11 :Base station receives the data block that controller is sent；
12:The base station determines the priority of each data block, is handled according to the priority of each data block, and the processing includes：
The base station, according to the priority of each data block, sends data block from high to low when the data block is the data block on same logic channel or same transmission channel；Or,
The base station is when sending data block, if the priority of the data block belongs to the high priority of setting, using the transmission power of normal sub-frames, sends the data block.Accordingly, opposite side can perform following flow：
Controller generates data block, and determines the priority of each data block；
The controller sends the data block to base station, and notifies the priority of each data block, and so that the base station is handled according to the priority of each data block, the processing includes：
When the data block is the data block on same logic channel or same transmission channel, according to the priority of each data block, data block is sent from high to low；Or,
When sending data block, if the priority of the data block belongs to the high priority of setting, using the transmission power of normal sub-frames, the data block is sent.
Optionally, can also again judge after priority is judged further whether weakon frame, you can choosing, the processing includes：The base station is when sending the data block of weakon frame in, if the priority of the data block of the weakon frame in belongs to the high priority of setting, using the transmission power of normal sub-frames, sends the data block of the weakon frame in. Optionally, in different systems, base station can have different titles, for example, in 2G systems, base station refers to base station transmitting-receiving station（Base Transceiver Station, BTS), in 3G systems, base station refers to NodeB, and in Long Term Evolution（Long Term Evolution, LTE) in system, base station refers to evolution base station（evolved NodeB, eNB ).
With the difference of system, base station can determine above-mentioned priority in different ways, for example, when base station is BTS or NodeB, base station can be the configured information for receiving controller transmission, priority is determined according to configured information, controller now can be respectively base station controller (Base Station Controller, BSC) and radio network controller（ Radio Network Controller, RNC ) .Or, when base station is eNB, because eNB has control function, eNB can be configured with itself, priority is determined according to setting, or, the controller different from eNB can also be included in LTE system, eNB can also receive the configured information of the controller, and priority is determined according to configured information.
Optionally, above-mentioned configured information can include same logic channel or transmission channel（It is abbreviated as logic channel/transmission channel）The priority of upper all data blocks, or, above-mentioned configured information can be corresponding with each data block, i.e., base station often receives a data block, a configured information corresponding with the data block can be received simultaneously, the configured information includes the priority of the data block.
In addition, above-mentioned configured information can also be limited to the instruction of the data block to same logic channel/transmission channel, the instruction of the data block of different logic channel/transmission channels can be used for.
Above-mentioned is by indicating mode so that base station determines the priority of each data block, optionally, transmission carrying that base station can also be mapped to according to data block, media access control flow（MAC-d flow) or queue determination.
For example, can be a transmission channel (Dedicated Channel, DCH multiple transmission carryings) are set up, different transmission carryings have different priority, afterwards in transmission of data blocks, different data blocks may map to be transmitted in different transmission carryings, now, the data block of transmission has different priority in different transmission carryings, the priority as the priority of the transmission carrying where data block can be defined as to the data block.
The number of the transmission carrying of above-mentioned foundation and the priority of each transmission carrying can be set, such as, it is that same transmission channel sets up two transmission carryings, the priority for setting first transmission carrying is N, the priority for setting second transmission carrying is M, it is assumed that M>N, then the priority of first transmission carrying of the priority ratio of second transmission carrying is high.
In another example, multiple queues can be configured for logic channel, different queues has different excellent First level, afterwards in transmission of data blocks, different data blocks may map to be transmitted in different queues, now, the data block transmitted in different queue has different priority, it is possible to which the priority of the queue where data block is defined as to the priority of the data block.Wherein, the information of correspondence queue can be carried in transmission by being mapped to the data block of different queue, so as to recipient according to the information of queue determine data block from queue, and according to from queue determine the priority of data block.Individual logic channel configures 2 queues, and the priority for setting first queue is N, and the priority for setting second queue is M, ^ M>N, then the priority of first queue of the priority ratio of second queue is high.
For another example medium education（Media Access Control, MAC) entity can include a variety of, a kind of MAC (MAC-hs) entity for correspondence high speed descending sharing channel, now, can be the multiple MAC-d flow of a MAC-hs entity configuration, different MAC-d flow are mapped to the queue with different priorities, afterwards in transmission of data blocks, different data blocks may map to be transmitted in different MAC-d flow, and different MAC-d flow are mapped to the queue of different priorities.Wherein, data block is first mapped to MAC-d flow and re-mapped when being transmitted in queue, MAC-d flow information can be carried in data block, recipient, which receives, can obtain MAC-d flow information after data block, according to MAC-d flow information can determine data block from MAC-d flow.Because MAC-d flow and queue have corresponding relation, corresponding queue is also assured that, then just the blunt priority according to corresponding queue is assured that the priority of data block.Individual logic channel configures 2 queues, and the priority for setting first queue is N, and the priority for setting second queue is M, ^ M>N, then the priority of first queue of the priority ratio of second queue is high.
In addition, the priority of data block all in above-mentioned same logic channel/Traffic Channel, can be that each data block has different priority, or, multiple data blocks have identical priority.
Furthermore, in the embodiment of the present invention, data block is to refer to data of message, order, signaling or bearer service information etc..
The present embodiment can determine the priority of each data block, according to the priority transmission data block, the priority using data block as granularity can be determined, therefore the priority of different pieces of information block on same logic channel or transmission channel can be distinguished, dispatch deal is made a distinction to different pieces of information block；When data block is During significant data, its priority is higher, the preferential transmission of significant data is ensured that when being sent according to priority, it is ensured that the Successful transmissions of significant data, or reduces the propagation delay time of significant data.Or, the present embodiment can also indicate that the priority of data block, the data block is not limited to the data block of same transmission channel/logic channel, can also can be sent according to the instruction when data block is in weakon frame in using the transmission power of normal sub-frames, it is ensured that significant data is sent.
Subsequent embodiment will be described with RNC, NodeB, user equipment (User Equipment, UE), it is to be understood that be referred to perform when being applied to other systems.In addition, subsequent embodiment is so that the data block on same logic channel has different priorities as an example, it would however also be possible to employ similar fashion is handled the different pieces of information block on same transmission channel.
Fig. 2 is the schematic flow sheet of another embodiment of data transmission method of the present invention, in the present embodiment, and RNC sends configured information to NodeB, and the configured information includes the priority of all data blocks on same logic channel, and the present embodiment includes：
21 :RNC is sent to NodeB includes configured information in the first data frame, first data frame, the configured information includes the priority of all data blocks on same logic channel.
For example, the sum of the data block on same logic channel is N, then pl, p2 N can be included in the configured information, wherein, pl, p2 pN represent the priority of each data block respectively.
Optionally, the priority of corresponding each data block can be indicated by the way of bit map, one data block of-individual bit correspondence.For example, above-mentioned pi, p2 pN is respectively 1 bit, when for " it is high priority to show corresponding data block during Γ, shows that corresponding data block is low priority when for " 0 ".
22:NodeB is scheduled processing to data block according to the priority of data block.
For example, NodeB dispatches data block successively according to the order of priority from high to low, priority such as 3 data blocks is respectively 1,2,3, so can successively dispatching priority be 3 data block, dispatching priority is 2 data block again, and last dispatching priority is 1 data block；Or, NodeB, even if the subframe where the data block is weakon frame, also sends the data block when the priority of data block belongs to high priority set in advance using the power of normal sub-frames.
For example, the priority of data block can be divided into two-stage in advance, respectively high priority and low priority, high priority is shown to be when the corresponding bit of data block is " 1 ", if instead being then shown to be low priority for " 0 ", then NodeB corresponding bits in the configured information received are " 1 " When, it is possible to determine that the priority of corresponding data block belongs to high priority set in advance.And it is " 1 " or " 0 " that RNC can determine to be sent to corresponding bit in NodeB configured information according to the type of data block, for example, when data block is switching command, bit shared by the corresponding priority of switching command in configured information this data block can be set to " 1 " by RNC, it is on the contrary, for other data blocks, the bit shared by the corresponding priority of other data blocks can be set to " 0 " by RNC.
Wherein, base station determines the position of weakon frame according to the configuration of controller；Or determine that the subframe that data are sent is weakon frame according to the instruction of data frame.
Downlink data dispatching can be completed by 21 22, NodeB.Further, since data block, which is RNC, is sent to NodeB, therefore, optionally, this method can also include before 21：
