Description

Error-tolerant method and device for PHICH channel transmission information

technical field

The embodiments of the present invention relate to communication technologies, and in particular to an error-tolerant method and device for transmitting information on a PHICH channel.

Background technique

In the LTE system, during the uplink Hybrid Automatic Repeat Request (HARQ) process, the eNode B sends the UL Grant to the UE, and the UE sends data at a specific location according to the received UL grant information, and the eNode B passes the PHICH (Physical HARQ Indicator Channel) Feedback to UE whether the data sent last time is ACK or NACK, UE demodulates PHICH information at a specific position, and then judges whether to resend data at a specific position according to the demodulated ACK/NACK information.

However, in the prior art, if the PHICH actually carries an ACK, but is decoded into a NACK by the UE, a series of problems will be caused. For example, in the user access phase, the UE sends an RRC Connection Request (RRC Connection Request, MSG3 for short) to the eNode B. After receiving the information correctly, the eNode B feeds back an ACK to the UE through the PHICH, but the UE demodulates the ACK into a NACK, and then the eNode B B will send RRC connection setup (RRC Connection Setup, referred to as MSG4) to UE. At this time, because UE demodulates ACK to NACK, UE thinks that MSG3 has not been received, and will retransmit MSG3 multiple times without processing MSG4.

In the prior art, when the above situation occurs, there is a risk in how the UE handles the MSG4 received, thereby causing access failure.

Fig. 1 is the flow chart of the first embodiment of the fault-tolerant method of PHICH channel transmission information of the present invention, as shown in Fig. 1, the method of this embodiment may include:

Step 101: If the base station correctly receives the first data sent by the mobile terminal, it returns a first response message to the mobile terminal at the first moment, and the first response message includes a message indicating that the first data has been received correctly. Data success description information; the first data is not the data sent by the mobile terminal in the last HARQ retransmission; the base station does not schedule new data of the mobile terminal at the first moment.

Wherein, the first moment may be a moment 4 TTI after the base station receives the first data sent by the mobile terminal.

Step 102: The base station sends a second response message to the mobile terminal when a preset time interval arrives after the first moment, and the second response message includes the success description information.

Wherein, the preset time interval may be 8TTI.

The successful description information in the above steps can be the ACK sent by the base station to the mobile terminal through the PHICH channel to indicate that the base station has correctly received the data sent by the mobile terminal. In this embodiment, the base station feeds back two ACKs for the same data, thereby improving the correct demodulation The probability of ACK, because according to the LTE protocol, after the base station sends ACK to the mobile terminal and schedules new data, after 4TTI, the new data sent by the mobile terminal is received, and then after 4TTI, the base station feeds back ACK to the mobile terminal for the data, so set here The time interval between the base station sending the ACK twice is 8TTI, that is, the preset time interval between the first response message and the second response message can be 8TTI, so that when the mobile terminal retransmits the data to the base station with an ACK demodulation error, The base station can send an ACK again for the data, thereby improving the demodulation success rate of the mobile terminal.

In this embodiment, when the base station correctly receives the first data sent by the mobile terminal, it returns a first response message to the mobile terminal, and the first response message includes a success message indicating that the first data has been correctly received. description information, the base station sends a second response message to the mobile terminal when the preset time interval arrives after the first moment, wherein the second response message includes the success description information, realizing When the data sent by the mobile terminal is correctly received, the successful description information is sent twice for the data, so as to improve the accuracy of the mobile terminal to correctly demodulate the successful description information fed back by the base station, thereby improving the correctness of the key process signaling in the interaction process guarantee.

Fig. 2 is the flow chart of the second embodiment of the fault-tolerant method of the PHICH channel transmission information of the present invention, as shown in Fig. 2, the method of this embodiment may include:

Step 201: After sending the first data to the base station, the mobile terminal receives the first response message returned by the base station at the first moment, and the first response message includes a successful description indicating that the first data has been received correctly Information; the first data is not the data sent by the mobile terminal in the last HARQ retransmission; the base station does not schedule new data of the mobile terminal at the first moment.

The first moment may be 4 TTI moments 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 a preset time interval arrives after the first moment, and the second response message includes the success description information.

Wherein, the preset time interval may be 8TTI.

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

If the mobile terminal successfully parses out the successful description information, it does not send any new data to the base station within a preset time interval after the first moment.

Specifically, after the mobile terminal sends the first data to the base station, after 4 TTIs, it receives the first response message returned by the base station at the first moment. If the mobile terminal mistakenly parses the success description information in the first response message into failure description information, then After 4TTI, the mobile terminal retransmits the first data to the base station, and after 4TTI, 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 8TTI.

Wherein, the success description information in the first response message and the second response message may be the ACK sent by the base station through the PHICH channel received by the mobile terminal, and the corresponding failure description information may be NACK.

In this embodiment, after the mobile terminal sends the first data to the base station, it receives the first response message returned by the base station at the first moment, and the first response message includes a success message indicating that the first data has been correctly received. description information, when the mobile terminal arrives at a preset time interval after the first moment, it receives the second response message sent by the base station, and the second response message includes the success description information, realizing For the same data, the mobile terminal receives twice the successful description information of the base station for the data, thereby improving the accuracy of the mobile terminal in parsing the successful description information, and further improving the accuracy of key process signaling during the interaction process.

Fig. 3 is the flow chart of the third embodiment of the fault-tolerant method for PHICH channel transmission information of the present invention. The embodiments shown in Fig. 1 and Fig. 2 illustrate the fault-tolerant method for PHICH channel transmission information provided by the present invention from the base station side and the mobile terminal side respectively, Figure 3 is an embodiment of the interaction process between the base station and the mobile terminal, as shown in Figure 3, the method of this embodiment may include:

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

Among them, the UL Grant carries the position information and modulation mode of sending uplink data.

Step 302, the UE sends data at a specific time according to the received UL Grant information, where the specific time is 4 TTI time after the eNode B issues the UL Grant.

Step 303, the eNode B successfully receives the data sent by the UE, and feeds back ACK to the UE through the PHICH channel.

Among them, step 303 requires two prerequisites, namely (1) no new data is scheduled when the eNode B sends the ACK to the UE; (2) the ACK sent by the eNode B this time is not the last retransmission feedback from the UE to the UE ACK.

Specifically, if the eNode B schedules new data at the time when the eNode B sends the ACK to the UE, according to the agreement, the UE sends new data to the base station at the 4TTI time, and the ACK sent by the eNode B to the UE at the 8TTI time , will be considered by the UE as feedback information for new data, so the precondition (1) is set here to ensure that the ACK sent by the eNode B to the UE at 8TTI is for the retransmission of data when the UE may demodulate errors Feedback; In addition, since the eNode B feeds back ACK for the last retransmission if the UE has reached the maximum number of times, even if the UE demodulates the ACK incorrectly, the UE cannot resend 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 to NACK, it resends data to the eNode B at 4 TTIs after receiving the ACK sent by the eNode B.

Under the two prerequisites in step 303, after the end of step 303, the eNodeB in the prior art will consider that it has completed the feedback of all received data. At this time, even if the UE demodulates errors in step 304, it will resend the data to the eNodeB , the eNode B will not send feedback information for the data, but in this implementation step 305 is executed after step 304.

Step 305: In step 303, when the eNode B sends the ACK to the UE, 8 TTIs have elapsed, and the eNode B sends the ACK for the retransmitted data in step 304 to the UE again through the PHICH channel, so that the UE can re-demodulate the ACK.

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

The eNode B successfully receives the data sent by the UE and feeds back an ACK to the UE. At this time, the UE may demodulate the ACK fed back by the eNode B into a NACK. Send the ACK for the last data, so as to improve the UE demodulation success rate and ensure the correctness of key process signaling. This implementation method is especially suitable for scenarios that need to ensure the accuracy of PHICH, such as signaling delivery such as access and handover.

Fig. 4 is a flow chart of Embodiment 4 of the fault-tolerant method for transmitting information on the PHICH channel of the present invention. This embodiment uses the technical solution of Embodiment 3 and applies the solution to the user access scenario. As shown in Fig. 4 , the embodiment of this embodiment Methods can include:

Step 401, eNode B sends UL Grant to UE.

Step 402, UE sends RRC Connection Request (MSG3) to eNode B.

Step 403, eNode B feeds back ACK through PHICH after receiving the information correctly.

Step 404, the UE demodulates the ACK fed back by the eNode B into a NACK, then the UE considers that the eNode B has not received the MSG3, and retransmits the MSG3 to the eNode B.

Step 405, eNode B sends ACK to UE again after 8 TTIs after feeding back ACK to UE through PHICH for the first time.

In the prior art, if the UE receives the ACK sent by the eNode B for the MSG3 feedback and demodulates the ACK to NACK, then the UE thinks that the eNode B has not received the MSG3, then it will resend the MSG3, and the eNode B feeds back to the UE After ACK, send RRC Connection Setup (MSG4) to the UE. At this time, because the UE thinks that the eNode B has not received MSG3, the UE will not process MSG4 when it receives MSG4. Instead, it will repeatedly send MSG3, which will cause user access to fail. In the embodiment, the eNode B sends the ACK to the UE again after 8 TTIs after feeding back the ACK to the UE through the PHICH for the first time, so that even if the UE demodulates the ACK to NACK for the first time, the probability of the second demodulation being correct will be greatly increased increase, so that the success rate of the access process can be improved, the correctness of key process signaling can be ensured, and the message delay in the access process can be reduced.
