FIG. 1 is a schematic flowchart diagram of an embodiment of a data transmission method according to the present invention.

11: The base station receives the data block sent by the controller;

12: The base station determines a priority of each data block, and performs processing according to a priority of each data block, where the processing includes:

And when the data block is a data block on the same logical channel or the same transport channel, the base station sends the data block according to the priority of each data block from high to low; or

When the base station transmits the data block, if the priority of the data block belongs to the set high priority, the data block is transmitted by using the transmit power of the normal subframe. Correspondingly, the other side can perform the following process:

The controller generates data blocks and determines the priority of each data block;

The controller sends the data block to the base station, and notifies the priority of each data block, so that the base station performs processing according to the priority of each data block, where the processing includes:

When the data block is a data block on the same logical channel or the same transport channel, the data block is sent from high to low according to the priority of each data block; or

When the data block is transmitted, if the priority of the data block belongs to the set high priority, the data block is transmitted using the transmission power of the normal subframe.

Optionally, after determining the priority, determining whether the subframe is further weak, that is, optional, the processing includes: when the base station sends the data block in the weak subframe, if the weak subframe The priority of the data block belongs to the set high priority, and the data block in the weak subframe is transmitted by using the transmit power of the normal subframe. Optionally, in different systems, the base station may have different names. For example, in a 2G system, a base station refers to a Base Transceiver Station (BTS). In a 3G system, a base station refers to a NodeB, and In a Long Term Evolution (LTE) system, a base station refers to an evolved NodeB (eNB).

The base station may determine the priority according to different manners, for example, when the base station is a BTS or a NodeB, the base station may receive the indication information sent by the controller, and determine the priority according to the indication information. The controllers can be a Base Station Controller (BSC) and a Radio Network Controller (RNC). Alternatively, when the eNB is an eNB, the eNB may perform the setting by itself, and the eNB may determine the priority according to the setting. Alternatively, the LTE system may also include a controller different from the eNB, and the eNB may also receive the indication of the controller. Information, based on the indication information to determine the priority.

Optionally, the foregoing indication information may include a priority of all data blocks on the same logical channel or transport channel (abbreviated as a logical channel/transport channel), or the indication information may be corresponding to each data block. That is, each time the base station receives a data block, it also receives an indication information corresponding to the data block, and the indication information includes the priority of the data block.

In addition, the above indication information may also be limited to the indication of the data block of the same logical channel/transport channel, and may also be used for the indication of the data block of the different logical channel/transport channel.

In the foregoing, the base station determines the priority of each data block by using an indication manner. Optionally, the base station may also determine according to the transmission bearer, the MAC-d flow, or the queue to which the data block is mapped.

For example, multiple transport bearers may be established for one Dedicated Channel (DCH), and different transport bearers have different priorities. After the data block is transmitted, different data blocks may be mapped to different transport bearers for transmission. At this time, the data blocks transmitted in different transport bearers have different priorities, for example, the priority of the transport bearer where the data block is located may be determined as the priority of the data block.

The number of the transport bearers established and the priority of each transport bearer may be set, for example, two transport bearers are established for the same transport channel, and the first transport bearer has a priority of N, and the second transport bearer is set. The priority is M. Assuming M>N, the priority of the second transport bearer is higher than the priority of the first transport bearer.

For another example, multiple queues can be configured for one logical channel, and different queues have different advantages. Pre-stage, then when the data block is transmitted, different data blocks can be mapped to different queues for transmission. At this time, the data blocks transmitted in different queues have different priorities, and the queue of the data block can be The priority is determined as the priority of the data block. The data block mapped to different queues carries the information of the corresponding queue when transmitting, so that the receiver determines the queue from which the data block comes according to the information of the queue, and determines the priority of the data block according to the queue from the queue. Two logical queues are configured with two queues. The priority of the first queue is set to N, and the priority of the second queue is set to M, ^3⁄4 M>N, then the priority of the second queue is higher than that of the first queue. The priority is high.

For example, a Media Access Control (MAC) entity may include multiple types, one is a MAC (MAC-hs) entity corresponding to a high speed downlink shared channel, and at this time, multiple MAC-hs entities may be configured. MAC-d flow, different MAC-d flows are mapped to queues with different priorities. After the data block is transmitted, different data blocks can be mapped to different MAC-d flows for transmission. Different MAC-d flows Map to queues of different priorities. When the data block is first mapped to the MAC-d flow and then mapped to the queue for transmission, the data block carries the information of the MAC-d flow, and the receiver can obtain the MAC-d flow information after receiving the data block, according to the MAC- The information of d flow can determine the MAC-d flow from which the data block comes from. Since the MAC-d flow has a corresponding relationship with the queue, the corresponding queue can be determined, and the priority of the data block can be determined according to the priority of the corresponding queue. Two logical queues are configured with two queues. The priority of the first queue is set to N, and the priority of the second queue is set to M, ^3⁄4 M>N, then the priority of the second queue is higher than that of the first queue. The priority is high.

In addition, the priority of all the data blocks in the same logical channel/traffic channel may be that each data block has a different priority, or multiple data blocks have the same priority.

Furthermore, in the embodiment of the present invention, the data block refers to a message, a command, a signaling, or data carrying service information.

In this embodiment, the priority of each data block may be determined, and according to the priority data block, the priority of the data block may be determined, so that the priority of different data blocks on the same logical channel or transport channel may be distinguished. Level, distinguishing between different data blocks; when the data block is When important data is used, its priority is higher. When sending according to priority, it can ensure the priority transmission of important data, ensure the successful transmission of important data, or reduce the transmission delay of important data. Or, the embodiment may also indicate a priority of the data block, where the data block is not limited to the data block of the same transport channel/logical channel, and according to the indication, the normal subframe may be used when the data block is in a weak subframe. The transmit power is sent to ensure important data is sent.

The subsequent embodiments will be described by RNC, NodeB, and User Equipment (UE). It can be understood that the implementation can be referred to when applied to other systems. In addition, the subsequent embodiments take the case that the data blocks on the same logical channel have different priorities, and different data blocks on the same transport channel can also be processed in a similar manner.

2 is a schematic flowchart of another embodiment of a data transmission method according to the present invention. In this embodiment, the RNC sends the indication information to the NodeB, and the indication information includes the priority of all the data blocks on the same logical channel. This embodiment includes :

21: The RNC sends a first data frame to the NodeB, where the first data frame includes indication information, where the indication information includes priorities of all data blocks on the same logical channel.

For example, if the total number of data blocks on the same logical channel is N, then the indication information may include pl, p2 N, where pl, p2 pN respectively indicate the priority of each data block.

Optionally, the priority of each corresponding data block may be indicated by using a bitmap, and the “bit” corresponds to one data block. For example, the above pi, p2 pN are 1 bit respectively. When it is "Γ, it indicates that the corresponding data block is high priority, and when it is "0", it indicates that the corresponding data block is low priority.

22: The NodeB performs scheduling processing on the data block according to the priority of the data block.

For example, the NodeB sequentially schedules data blocks according to the order of priority from high to low. For example, if the priority of the three data blocks is 1, 2, and 3, respectively, the data blocks with the priority level 3 may be scheduled in sequence, and the priority of the scheduling is a data block of 2, last scheduling a data block with a priority of 1; or, when the priority of the data block belongs to a preset high priority, the NodeB uses the subframe even if the data block is a weak subframe. The power of the normal subframe transmits the data block.

For example, the priority of the data block can be divided into two levels in advance, which are high priority and low priority respectively. When the bit corresponding to the data block is "1", it indicates high priority, and if it is "0". Indicated as low priority, then the corresponding bit in the received indication information of the NodeB is "1". At this time, it can be determined that the priority of the corresponding data block belongs to a preset high priority. The RNC may determine, according to the type of the data block, that the corresponding bit in the indication information sent to the NodeB is "1" or "0". For example, when the data block is a handover command, the RNC may switch the command in the indication information. The bit occupied by the priority corresponding to the data block is set to "1". Conversely, for other data blocks, the RNC can set the bit occupied by the priority corresponding to the other data block to "0".

The base station determines the location of the weak subframe according to the configuration of the controller; or determines that the subframe in which the data is transmitted is a weak subframe according to the indication of the data frame.

Through 21~22, NodeB can complete downlink data scheduling. In addition, since the data block is sent by the RNC to the NodeB, therefore, the method may further include:

The RNC determines the priority of each data block. For example, the RNC determines the type of the data block, for example, when the data block is a handover command, it is determined as a high priority data block. Then, when the RNC sends the indication information, the corresponding indication information may be carried according to the determined priority of the data block. For example, when the data block is a handover command, the RNC may set the bit occupied by the priority corresponding to the data block of the handover command in the indication information to "1", and conversely, for other data blocks, the RNC may use other data blocks. The bit occupied by the corresponding priority is set to "0".

The RNC sends the data block to the NodeB.

Optionally, when the RNC sends the data block to the NodeB, the radio link control (RLC) layer can cascade the sub-blocks sent by the upper layer according to the amount of data that can be transmitted by the bottom layer, for example, RLC. The layer may cascade multiple sub-blocks sent by the Packet Data Convergence Protocol (PDCP) layer into one data block and then send it to the Media Access Control (MAC) layer. In this embodiment, in order to make the priority of the data blocks obtained by the concatenation accurate, sub-blocks having the same priority may be cascaded together at the time of cascading, and sub-blocks of different priorities may not be cascaded.

Optionally, after 22, the method may further include: the UE supports the out-of-order transmission on the received data block.

Specifically, the reception of data can be divided into an acknowledgement mode and a non-confirmation mode, and the prior art only supports sequential delivery when confirming the mode. In this embodiment, both the confirmation mode and the non-confirmation module support the out-of-order delivery.

For example, after the RLC layer of the UE receives the out-of-order data block, if the data block is a high-priority data block, the UE continues to deliver the data block to the upper layer. Specifically, assume that the UE is transmitted in order. The 4th data block should be received, but when the UE receives the 5th data block, if the 5th data block is a high priority data block, if the data block is a handover command, the RLC layer of the UE is still submitted upward. The data block. This can reduce the transmission delay of important data, and can also send feedback information to the sender in time.

In this embodiment, the RNC sends the indication information to the NodeB, so that the NodeB can learn the priority of each data block, and then, according to the priority scheduling data, the high priority data can be preferentially transmitted, and the success rate of the important data is improved. Or reducing the transmission delay; this embodiment simultaneously indicating the priority of multiple data blocks can reduce the overhead.

FIG. 3 is a schematic flowchart of another embodiment of a data transmission method according to the present invention. In this embodiment, the RNC sends the indication information to the NodeB, and the indication information corresponds to the data block, and the embodiment includes:

31: The RNC sends a second data frame to the NodeB, where the second data frame includes a data block and indication information corresponding to the data block, where the indication information is a priority.

For example, the second data frame contains D and p, D is a data block, and p is the priority of the data block. Optionally, the priority of each data block can be represented by 1 bit. For example, when it is "1", it indicates that the corresponding data block is high priority, and when it is "0", it indicates that the corresponding data block is low priority. Level, and vice versa. The RNC can determine the corresponding priority according to the data type. For example, when the data block is a handover command, the RNC can set the bit occupied by the priority corresponding to the data block of the handover command to "1", and vice versa, for other data. Block, the RNC can set the bit occupied by the priority corresponding to other data blocks to "0".

By prioritizing the data block by transmitting one data block, the NodeB can be made to prioritize each data block.

32: The NodeB performs scheduling processing on the data block according to the priority of the data block.

For example, the NodeB sequentially schedules data blocks according to the order of priority from high to low. For example, if the priority of the three data blocks is 1, 2, and 3, respectively, the data blocks with the priority level 3 may be scheduled in sequence, and the priority of the scheduling is 2 data block, last scheduling data block with priority 1; or

When the priority of the data block belongs to a preset high priority, for example, when the corresponding bit is "1", even if the subframe in which the data block is located is a weak subframe, the power transmission of the normal subframe is used. The data block. For details, refer to the previous embodiment, and details are not described herein.

Optionally, similar to the previous embodiment, the RNC may also first determine the priority of the data block to send corresponding indication information. In addition, optionally, when the RNC sends the data block to the NodeB, the RLC layer of the RNC does not cascade the sub-blocks of the same priority when cascading.

In addition, the UE may, when receiving the data block, support the out-of-order delivery according to the priority, that is, when the UE receives the out-of-order data block, if the priority of the data block is higher, the UE still goes to the upper layer. submit.

For the above specific details, refer to the description of the embodiment shown in FIG. 2.

In this embodiment, the RNC sends the indication information to the NodeB, so that the NodeB can learn the priority of each data block, and then, according to the priority scheduling data, the high priority data can be preferentially transmitted, and the success rate of the important data is improved. Or reduce the transmission delay; in this embodiment, the corresponding priority is transmitted simultaneously with the data block, and additional overhead can be avoided.

FIG. 4 is a schematic flowchart of another embodiment of a data transmission method according to the present invention. In this embodiment, a NodeB determines a priority according to a transmission bearer from which a data block is derived.

41: The RNC and the NodeB establish multiple transport bearers for each transport channel, and each transport bearer has a different priority.

For example, the RNC may indicate that the NodeB completes the transmission bearer setup and the priority setting, or the RNC and the NodeB pre-agreed the priority of each transport bearer.

42: The RNC sends the data blocks to the NodeB in their respective transport bearers.

For example, the RNC can determine the priority of each data block, and then send the high priority data block in the high priority transport bearer and the low priority data block in the low priority transport bearer.

43: The NodeB determines the priority of the data block according to the transport bearer from which the data block is derived.

For example, when a data block comes from a high-priority transport bearer, it is determined that the data block is high-priority, and when the data block comes from a low-priority transport bearer, it is determined that the data block is low-priority.

44: The NodeB performs scheduling processing on the data block according to the priority of the data block.

When the priority of the data block belongs to a preset high priority, for example, when the corresponding bit is "1", even if the subframe in which the data block is located is a weak subframe, the power transmission of the normal subframe is used. The data block. For details, refer to the previous embodiment, and details are not described herein. Optionally, when the RNC sends the data block to the NodeB, the RLC layer of the RNC does not cascade the sub-blocks of the same priority when cascading.

Optionally, when receiving the data block, the UE may support the out-of-order delivery according to the priority, that is, when the UE receives the out-of-order data block, if the priority of the data block is higher, the UE still submits the upper layer.

In addition, in this embodiment, the transmission bearers to which the data blocks are mapped have different priorities as an example. Optionally, different priorities may be set for the MAC-d flow stream or the queue to which the data block is mapped, and the priority of the data block is determined according to the MAC-d flow flow from the data block or the priority of the queue.

In this embodiment, the priority of the data block is determined by the bearer from the data block, and the priority of the data block can be determined without additional indication. After the data can be scheduled according to the priority, the high priority data can be preferentially transmitted and improved. The success rate of important data transmission or the transmission delay.

FIG. 5 is a schematic flowchart of another embodiment of a data transmission method according to the present invention. The difference from the foregoing embodiment is that the uplink transmission is an example. This embodiment includes:

51: The UE determines a priority of each of the plurality of transport bearers.

For example, the RNC may indicate the priority of each transport bearer of the UE, or the RNC and the UE pre-agreed the priority of each transport bearer.

52: The UE determines the priority of each data block, and sends the high priority data block to the NodeB on the high priority transmission bearer.

For example, the UE may determine according to the type of the data block, for example, when the data block is a handover command, it is determined as a high priority data block.

Afterwards, the UE sends the handover command to the NodeB on the high priority transmission bearer. Optionally, when the UE sends the data block to the NodeB, the RLC layer may cascade the sub-blocks sent by the upper layer according to the amount of data that can be transmitted by the bottom layer. For example, the RLC layer may send multiple sub-data sent by the PDCP layer. The block is cascaded into one data block and then sent to the MAC layer. In this embodiment, in order to make the priority of the data blocks obtained by the concatenation accurate, sub-blocks having the same priority may be cascaded together at the time of cascading, and sub-blocks of different priorities may not be cascaded.

Optionally, the NodeB supports out-of-order delivery of the received data block.

For example, when the RLC layer of the NodeB receives the out-of-order data block, if the data block is a high-priority data block, the NodeB continues to deliver the data block to the upper layer. Specifically, it is assumed that the UE in the order of transmission should receive the 4th data block, but if the UE receives the 5th data block, if the 5th data block The data block is a high priority data block. If the data block is a handover command, the RLC layer of the NodeB still delivers the data block upward. This can reduce the transmission delay of important data, and can also send feedback information to the sender in time.

In addition, in this embodiment, the transmission bearers to which the data blocks are mapped have different priorities as an example. Optionally, the MAC-d flow stream or the queue to which the data block is mapped may also be set with different priorities, and the UE maps the high priority data block to the high priority MAC-d flow flow or the high priority queue. Send in.

In this embodiment, according to the priority of the data block, the high-priority data block is carried on the high-priority transmission bearer, and the high-priority data transmission can be preferentially ensured, and the transmission success rate of the important data is improved or the transmission time is reduced. Delay.

It can be understood that, in the foregoing embodiment, a data block indicating the same transport channel/logical channel is taken as an example, but for a scenario in which data in a weak subframe is transmitted by using a transmit power of a normal subframe, the data block is not limited to the same. A transport channel/logical channel, which may be a data block of a different transport channel/logical channel.

Optionally, the present invention further provides an embodiment, when the UE determines that a high priority data packet is sent, indicating that the base station has high priority data transmission. For example, an indication of adding a high priority packet through Scheduling Information (SI) or other MAC packets, or adding a MAC packet indicates that a high priority packet is sent.

That is, the present invention also gives the following embodiments:

The terminal determines that the first data is to be sent, and the first data belongs to the set high priority data.

Scheduling authorization;

The terminal receives a scheduling grant of a normal subframe sent by the base station, and sends the first data according to a scheduling grant of the normal subframe.

Optionally, the indication information may be that the terminal sends after the first data is determined to be high priority data, and the first data belongs to the data sent during the uplink weak subframe.

Or, perform the following process for the base station:

The base station receives the indication information sent by the terminal, where the indication information is used to indicate that the base station sends a scheduling authorization of a normal subframe to the terminal, where the indication information is sent by the terminal when determining that the first data is to be sent. The first data belongs to the set high priority data; The base station sends a scheduling grant of the normal subframe to the terminal according to the indication, so that the terminal sends the first data according to the scheduling authorization of the normal subframe.

Optionally, after determining the priority, whether the weak subframe is determined, that is, after the base station receives the indication information, if the data of the UE is determined to be high priority data, and the high priority data belongs to the uplink weak subframe. The transmitted base station ignores the transmission behavior of the weakened subframe, and sends a scheduling grant for the normal subframe to the UE. Optionally, the UE may determine, according to the type of the data, whether the corresponding data belongs to the set high priority data. For example, when the data is a measurement report, or an acknowledgement message of the handover command, the UE may determine that the data belongs to the set high. Priority, that is, the data is the first data described above.

Optionally, after receiving the indication that the high-priority data packet is not received by the base station, if the data of the UE is determined to be sent during the uplink weak subframe, the base station resumes the weak subframe transmission behavior, and sends the UE lower than the normal subframe. Scheduling authorization.
