Description

Fault-tolerant method and device for transmitting information on PHICH channel

The embodiments of the present invention relate to communication technologies, and in particular, to a fault tolerance method and apparatus for transmitting information on a PHICH channel. Background technique

In the LTE system, in the process of Hybrid Automatic Repeat Request (HARQ), the eNode B sends a UL Grant to the UE, and the UE sends data according to the received UL grant information at a specific location, and the eNode B passes the PHICH. (Physical HARQ indicator channel) Feed back to the UE whether the last transmitted data is ACK or NACK, the UE demodulates the PHICH information at a specific location, and then determines whether it is necessary to resend the data at a specific location according to the demodulated AC/NACK information.

However, in the prior art, if the PHICH actually carries an ACK, but the UE is decomposed into a NACK, a series of problems are caused. For example, in the user access phase, the UE sends an RRC Connection Request (MSG3) to the eNode B. After receiving the information correctly, the eNode B feeds back the ACK to the UE through the PHICH, but the UE demodulates the ACK into a NACK, and then the eNode. B will send the RRC Connection Setup (MSG4) to the UE. At this time, since the UE demodulates the ACK into a NACK, the UE considers that the MSG3 is not received, and retransmits the MSG3 multiple times without processing the MSG4.

In the prior art, when the above situation occurs, the UE receives a risk when the MSG4 is processed, and the access fails. Summary of the invention

The successfully described information in the foregoing step may be an ACK sent by the base station to the mobile terminal through the PHICH channel, to indicate that the base station correctly receives the data sent by the mobile terminal. In this embodiment, the base station feeds back two ACKs to the same data, thereby improving the correct solution. The probability of ACK is adjusted. After the base station sends an ACK to the mobile terminal and schedules new data according to the LTE protocol, after receiving the new data, the new data transmitted by the mobile terminal is received, and then the 4TTI base station feeds back the ACK to the mobile terminal for the data, so here The time interval for the eNB to send the ACK twice is 8 TTI, that is, the preset time interval between the first response message and the second response message may be 8 TTI, so that when the mobile terminal retransmits the data to the base station by using the ACK demodulation error. The base station can send an ACK again for the data, thereby improving the demodulation success rate of the mobile terminal.

Step 201: After the mobile terminal sends the first data to the base station, the first response message that is returned by the base station at the first moment is received, where the first response message includes a success message that the first data is correctly received. Descriptive information; the first data is not data sent by the last HARQ retransmission of the mobile terminal; the base station does not schedule new data of the mobile terminal at the first moment.

The first moment may be a 4TTI moment after the mobile terminal sends the first data to the base station. Step 202: The mobile terminal receives a second response message sent by the base station when the preset time interval of the mobile terminal arrives, where the second response message includes the success description information.

The preset time interval may be 8 TTI.

Further, if the mobile terminal erroneously parses the success description information into failure description information, retransmitting the first data to the base station within a preset time interval after the first time; or

Specifically, after the mobile terminal sends the first data to the base station, after receiving the first response message returned by the base station at the first moment, if the mobile terminal incorrectly parses the successful description information in the first response message into the failure description information, After the mobile terminal retransmits the first data to the base station, the mobile terminal receives the second response message sent by the base station, that is, the time interval between the first response message and the second response message is 8 ΤΤΙ.

Descriptive information, the mobile terminal receives a second response message sent by the base station when the preset time interval after the first time arrives, and the second response message includes the success description information, and implements For the same data, the mobile terminal receives the success description information of the base station for the data twice, thereby improving the correct rate of the successful description information of the mobile terminal, and further improving the accuracy of the key process signaling in the interaction process.

3 is a flowchart of a third embodiment of a fault tolerant method for transmitting PHICH channel information according to the present invention. The method shown in FIG. 1 and FIG. 2 respectively illustrates a fault tolerance method for PHICH channel transmission information provided by the present invention from a base station side and a mobile terminal side, FIG. 3 is a schematic diagram of an interaction process between a base station and a mobile terminal. As shown in FIG. 3, the method in this embodiment may include:

Step 301: A base station (eNode B) sends an uplink resource assignment signaling (UL Grant) to a mobile terminal (UE).

The UL Grant carries location information and modulation methods for transmitting uplink data.

Step 302: The UE sends data at a specific time according to the received information of the UL Grant, where the specific time is 4 TTI times after the UL Grant is sent by the eNode B.

Step 303: The eNode successfully receives data sent by the UE, and then uses the PHICH channel to

The UE feeds back an ACK.

Step 303 requires two preconditions, that is, (1) no new data is scheduled when the eNode B sends an ACK to the UE; (2) the ACK sent by the eNode B is not the last retransmission feedback of the UE to the UE. ACK.

Specifically, if the eNode B schedules new data when the eNode B sends the ACK to the UE, the UE sends the new data to the base station at the 4TTI time according to the protocol, and the ACK sent by the eNode B to the UE at the 8TTI time. It is considered by the UE to be the feedback information for the new data. Therefore, the precondition (1) is set here to ensure that the ACK sent by the eNode B to the UE at the 8TTI time is to retransmit the data when the UE is likely to demodulate the error. Feedback; in addition, since the UE has reached the maximum number of times, the eNode B feeds back an ACK for the last retransmission, thus The UE is caused to demodulate the ACK, and the UE cannot resend the data to the eNode B, so the precondition (2) is set here.

Step 304: The UE demodulates the PHICH information sent by the eNode B. When the UE demodulates the ACK into a NACK, the UE resends the data to the eNode B at the four TTI times after the eNode B receives the ACK.

Under the two preconditions in step 303, after the end of step 303, the eNode B in the prior art considers that the feedback of all the received data is completed, and then the UE demodulates the error in step 304, and then re-sends to the eNode B. The data is sent, the eNode B does not send feedback information to the data, and the implementation performs step 305 after step 304.

Step 305: In step 303, the eNode B sends an ACK to the UE for 8 TTIs, and the eNode B sends an ACK for the retransmitted data in step 304 to the UE through the PHICH channel, so that the UE re-demodulates the ACK. .

That is, through the above steps, the eNode B sends two ACKs to the UE for the same data to improve the UE demodulation success rate.

The eNode B successfully receives the data sent by the UE, and feeds back the ACK to the UE. At this time, the UE may demodulate the ACK fed back by the eNode B into a NACK. In this embodiment, the UE re-transmits the UE through 8 TTIs when the ACK is sent to the UE by the eNode B. The ACK for the previous data is sent, so that the UE demodulation success rate is improved, and the correctness of the key process signaling is ensured. The method of the present embodiment is particularly applicable to a scenario in which PHICH accuracy is required, such as access, handover, and the like.

4 is a flowchart of Embodiment 4 of a fault tolerant method for transmitting PHICH channel information according to the present invention. This embodiment uses the technical solution of the third embodiment to apply the solution to a user access scenario. As shown in FIG. 4, the embodiment is as shown in FIG. Methods can include:

Step 401: The eNode B sends a UL Grant to the UE.

Step 402: The UE sends an RRC Connection Request (MSG3) to the eNode B. Step 403: After the eNode B receives the information correctly, the ACK is fed back through the PHICH. Step 404: The UE demodulates the ACK fed back by the eNode B into a NACK, and the UE considers that the eNode B does not receive the MSG3, and then retransmits the MSG3 to the eNode B.

Step 405: After the ACK is fed back to the UE through the PHICH for the first time, the eNode B sends an ACK to the UE again after 8 TTIs.

In the prior art, if the UE receives the MSG3 feedback sent by the eNode B for it, ACK, demodulate the ACK into a NACK, if the UE considers that the eNode B does not receive the MSG3, it will resend the MSG3, and the eNode B sends an RRC Connection Setu (MSG4) to the UE after the ACK is fed back to the UE. If the eNode B does not receive the MSG3, the UE does not process the MSG4, and the MSG3 is not sent. The user access fails. In this embodiment, the eNode B passes the PHICH to the UE for the first time. The TTI sends an ACK to the UE again, so that even if the UE demodulates the ACK into a NACK for the first time, the probability of correcting the second demodulation is greatly increased, thereby improving the success rate of the access procedure and ensuring key process signaling. Correctness and reduced message delay during access.
