Description

  The present invention relates to communication technology, and more particularly, to an uplink data transmission confirmation apparatus, device, and method.

  Currently, the Long Term Evolution (LTE for short) project of the 3rd Generation Partnership Project (hereinafter 3GPP for short) is related to special application scenarios for terminals. Advocates research theme of coverage extension. That is, this project provides coverage extension assistance to allow terminals to access the network and obtain services for terminals with relatively high losses, such as terminals located underground. Signal repetition is one way to implement coverage extension. Different terminals are located in different environments and require different degrees of coverage extension. That is, different terminals have different coverage extension requirements. Using signal repetition as an example, different terminals also require different amounts of signal repetition. After the terminal transmits the uplink data to the base station, the terminal needs to know whether the uplink data has been successfully transmitted, that is, whether the base station has correctly received the uplink data. According to the existing protocol, the base station transmits a physical hybrid automatic repeat request ARQ indication channel (Physical Hybrid ARQ Indicator Channel, hereinafter abbreviated as PHICH) signaling to the terminal, which allows the terminal to transmit uplink data. Know the transmission status. In the coverage extension scenario, the base station needs to repeatedly transmit PHICH signaling. As a result, the UE needs to correctly receive the PHICH signaling, determine whether the base station correctly received the previous uplink data according to the PHICH signaling, and retransmit the previous uplink data to the base station. You can decide whether there is.

  In the prior art, in order to reduce resource consumption due to repeated transmission of PHICH (a relatively large amount of resources is consumed by repeated transmission of PHICH signaling), a physical downlink control channel (hereinafter referred to as “physical downlink control channel”) Uplink data confirmation can be instructed using a new data indicator (abbreviated as PDCCH) signaling new data indicator (New Data Indicator, hereinafter abbreviated as NDI) field. If NDI indicates that PDCCH signaling schedules transmission of new data, it indicates that the previously transmitted data of the terminal has been successfully received, or NDI schedules transmission of old data by PDCCH signaling Indicates that the previously transmitted data of the terminal is not normally received, and that the terminal needs to retransmit the previous uplink data to the base station.

  However, in the prior art, when the uplink data transmitted by the terminal is confirmed, the uplink data is a non-random access response message (Message3, hereinafter referred to as Msg3 for short) and is scheduled by PDCCH signaling. The base station still needs to send PDCCH signaling to the terminal if it is successfully received by the base station, so that the terminal It can be confirmed that the data has been received normally. In addition, in the coverage extension scenario, PDCCH signaling also needs to be transmitted repeatedly to the terminal, causing resource waste. If the uplink data is Msg3 transmitted without being scheduled by PDCCH signaling, the prior art cannot confirm whether Msg3 is transmitted correctly.

  Embodiments of the present invention provide an apparatus, a device and a method for confirming uplink data transmission, which causes a waste of resources when the terminal confirms whether the transmitted uplink data is successfully transmitted, And it is used in order to solve the technical problem in the prior art that the prior art cannot confirm whether the Msg3 message has been transmitted normally.

  Embodiments of the present invention relate to a scenario of processing for confirming whether uplink data transmitted by a terminal has been normally transmitted without extending the PHICH channel by the terminal in the scenario of coverage extension.

  FIG. 1 is a schematic structural diagram of a first embodiment of an uplink data transmission confirmation apparatus according to the present invention. The device may be a terminal or may be integrated into the terminal. As shown in FIG. 1, the confirmation device 50 includes a transceiver module 10 configured to transmit uplink data to the base station, and whether the first physical downlink control channel signaling transmitted by the base station has been received. Detection module 11 configured to detect the first preset time period and obtain a detection result, and a determination configured to determine whether uplink data has been successfully transmitted according to the detection result Module 12 is included.

  Specifically, the transceiver module 10 knows uplink resources allocated by the base station to transmit uplink data according to the scheduling by the base station, and the transceiver module 10 performs uplink data on these uplink resources. To the base station, where the uplink data herein may be non-Msg3 or Msg3. In addition, when the uplink data transmitted by the transceiver module 10 is non-Msg3, the base station needs to perform scheduling using PDCCH signaling. Or, when the uplink data transmitted by the transceiver module 10 is Msg3, the base station does not need to perform scheduling using PDCCH signaling, but instead, Random Access Response (hereinafter referred to as RAR for short) ) Schedule using messages. Thereafter, the uplink data transmission confirmation device 50 starts the first timer. The first timer corresponds to the first preset period. Optionally, the length of the first preset period may be configured by the base station or determined according to rules predefined by the verification device 50 and the base station. The length of the first preset period is related to the coverage extension requirement of the terminal.

  The detection module 11 detects whether the first physical downlink control channel signaling transmitted by the base station within the second preset period has been received within the first preset period and obtains the detection result, Thus, the first physical downlink control channel may be PDCCH signaling or ePDCCH (enhanced PDCCH, enhanced PDCCH) signaling, and is not limited in this embodiment of the present invention. In the second preset period in this specification, specifically, for non-Msg3, the base station starts the second timer after scheduling device 50 and transmits uplink data, or for Msg3 The base station starts the second timer after transmitting the RAR message to the confirmation device 50. The corresponding second preset period is set for all the second timers mentioned in this document, and the base station controls the first physical downlink control regardless of whether the uplink data is non-Msg3 or Msg3. As long as the channel signaling is transmitted, the second preset period is set. This is to ensure that the confirmation device 50 can correctly receive the first physical downlink control channel signaling before the first preset period expires. Optionally, the second preset period may be configured by the base station or may be configured by the base station according to rules predefined by the base station and the verification device 50. Optionally, the second preset period is configured by the base station according to the coverage extension requirement level of the confirmation device 50, or the coverage extension requirement level and the second preset period predefined by the base station and the confirmation device 50 Is determined by the base station in accordance with the mapping relationship. The coverage extension requirement level of the confirmation apparatus 50 in this specification may be a coverage extension requirement of the terminal, or may be a coverage extension requirement of a message transmitted between the terminal and the base station. It should be noted. For example, if the terminal coverage extension requirements are different, or if the coverage extension requirements for messages transmitted between the terminal and the base station are different, the amount of time required for signal repetition is different to meet the extension requirements. Therefore, the difference is that, after transmitting uplink data, after scheduling the terminal to transmit uplink data for the time it takes for the terminal to wait for the first physical downlink control channel signaling, the terminal transmits Time it takes to wait for the received uplink data or the first physical downlink control channel signaling to reach the terminal after the base station sends the first physical downlink control channel signaling May exist in time. Accordingly, the first preset period or the second preset period is related to the coverage extension requirement.

  Finally, the determination module 12 may determine whether the uplink data has been normally transmitted according to the detection result obtained by the detection module 11.

  According to the uplink data transmission confirmation apparatus provided in this embodiment of the present invention, after the transmission / reception module transmits uplink data to the base station, the detection module transmits the first physical downlink control channel transmitted by the base station. -Detect whether the signaling has been received and obtain the detection result, and the determination module determines whether the uplink data has been transmitted normally according to the detection result of the detection module. According to this embodiment of the invention, the detection module determines whether a first physical downlink control channel signaling has been received within a first preset time period, after which the decision module determines whether the uplink data According to the detection result, so that if uplink data is successfully received, the base station sends a physical downlink control channel signaling specially, and the uplink data is There is no need to allow the verification device to verify whether the transmission was successful. Therefore, the overhead of physical downlink control channel signaling is reduced, and the confirmation device can confirm whether Msg3 is transmitted normally using the first physical downlink control channel signaling.

  Further, based on the embodiment shown in FIG. 1, the transceiver module 10 is further configured to receive the second physical downlink control channel signaling transmitted by the base station before transmitting the uplink data, wherein Thus, the second physical downlink control channel signaling is used to instruct the transceiver module 10 to transmit uplink data.

  Specifically, when the transceiver module 10 transmits uplink data to a base station, the uplink data generally needs to be transmitted on uplink resources allocated by the base station. Therefore, the base station uses the second physical downlink control channel signaling to notify the confirmation device 50 of the resource that needs to transmit uplink data, and thus the base station transmits the transmission / reception module 10 Uplink data can be received on such resources.

  Based on the embodiment of FIG. 1, as a possible implementation of this embodiment of the present invention, this embodiment confirms whether the uplink data was successfully transmitted when the uplink data is non-Msg3. It relates to processing to be confirmed by the device 50. Further, the first physical downlink control channel signaling is used to instruct the transceiver module 10 to retransmit uplink data. Specifically, the determination module 12 indicates that the detection result indicates that the detection module 11 has not detected the first physical downlink control channel signaling transmitted by the base station within the first preset period. The uplink module has successfully transmitted or the detection result indicates that the detection module 11 has detected the first physical downlink control channel signaling transmitted by the base station within the first preset period. If so, it is configured to determine that the uplink data is not transmitted normally.

  Specifically, when uplink data transmitted from the transceiver module 10 to the base station is normally transmitted, in the prior art, the base station transmits PDCCH signaling and the base station receives the uplink data normally. The confirmation device 50 is notified of this. However, in the present embodiment, the base station does not need to specifically transmit PDCCH signaling to the confirmation device 50. Instead, the detection module 11 in the confirmation device 50 receives the first physical downlink control channel signaling. Detected within a first preset period, where the first physical downlink control channel signaling is used to instruct the transceiver module 10 to retransmit previously transmitted uplink data . If the detection result is that the first physical downlink control channel signaling is detected, the determination module 12 determines that the base station has not received the uplink data normally, i.e., the uplink data. Confirms that the transmission is not normally transmitted, the transceiver module 10 retransmits the previously transmitted uplink data to the base station according to the first physical downlink control channel signaling. If the detection result indicates that the first physical downlink control channel signaling has not been detected, the determination module 12 determines that the base station has successfully received the uplink data. Therefore, when uplink data is normally received, the base station does not need to specifically send PDCCH signaling or ePDCCH signaling to the confirmation device 50 to notify that the base station has successfully received uplink data. This reduces the physical downlink control channel signaling overhead.

  Based on the embodiment shown in FIG. 1, as another possible implementation of this embodiment of the present invention, the present embodiment determines whether the uplink data has been successfully transmitted when the uplink data is Msg3. This is related to the process of confirming by the confirmation device 50. Further, the first physical downlink control channel signaling is used to instruct the transmission / reception module 10 to receive a random access contention resolution message (Message4, hereinafter abbreviated as Msg4) transmitted by the base station. If the detection module 11 detects that the detection module 11 has detected the first physical downlink control channel signaling transmitted by the base station within the first preset period, the uplink data is normal. Or the detection result indicates that the detection module 11 has not detected the first physical downlink control channel signaling transmitted by the base station within the first preset period. , Further configured to determine that uplink data is not being transmitted normally.

  Specifically, in the random access response process, the confirmation device 50 may access the base station randomly. That is, when the transceiver module 10 transmits uplink data, the base station does not need to perform scheduling using PDCCH signaling, but instead performs scheduling using RAR messages.

  When the uplink data is Msg3, it cannot be confirmed by the prior art whether the uplink data is correctly transmitted. However, in this embodiment, when the uplink data transmitted by the transceiver module 10 is normally transmitted, the base station transmits the first physical downlink control channel signaling to the confirmation device 50, where Physical downlink control channel signaling is used to instruct the transceiver module 10 to receive Msg4 transmitted by the base station on the corresponding resource. That is, the detection module 11 in the confirmation device 50 detects whether the first physical downlink control channel signaling is received within the first preset period, and the first physical downlink control channel signaling is detected. The determination module 12 determines that the base station has successfully received the uplink data, and in this case, the transceiver module 10 receives the Msg4 transmitted by the base station according to the first physical downlink control channel signaling. To do.

  Further, the first preset period is configured by the base station according to the coverage extension requirement level of the confirmation device 50, or the first preset period is defined as the coverage extension requirement level predefined by the confirmation device 50 and the base station. It is determined by the confirmation device 50 according to the mapping relationship with the first preset period.

  According to the uplink data transmission confirmation apparatus provided in this embodiment of the present invention, the transmission / reception module transmits Msg3 to the base station, and the detection module receives the first physical downlink control channel signaling transmitted by the base station. The detection module obtains a detection result by detecting whether it has been received, and the determination module determines whether the uplink data has been normally transmitted according to the detection result of the detection module.

  Specifically, when a terminal transmits uplink data, it is necessary to transmit the uplink data on a corresponding resource. Therefore, the confirmation device 60 needs to notify the terminal to allocate the corresponding resource to the terminal and to transmit the uplink data on such resource. That is, the first transmission module 22 in the confirmation device 60 transmits the second physical downlink control channel signaling to the terminal, where the second physical downlink control channel signaling transmits the uplink data to the terminal. Used to command

Further, the first physical downlink control channel signaling is used to instruct the terminal to transmit uplink data. Specifically, the determination module 21 determines that the first physical downlink control when the detection result indicates that the detection and reception module 20 has received the uplink data transmitted by the terminal within the second preset period. Instructs the first transmission module 22 not to transmit channel signaling to the terminal, so that the terminal determines that the uplink data has been successfully transmitted or the detection result is the uplink transmitted by the terminal. Instructs the first transmission module 22 to transmit the first physical downlink control channel signaling to the terminal if the detection and reception module 20 has not received within the second preset period. Thus, the terminal is configured to determine that the uplink data was not successfully transmitted.

  Specifically, when the confirmation device 60 does not normally receive the uplink data transmitted by the terminal, in the present embodiment, the first physical down link used to instruct the terminal to retransmit the uplink data. Link control channel signaling is sent to the terminal, as is the prior art. However, if the confirmation device 60 normally receives the uplink data transmitted by the terminal, the prior art indicates that the confirmation device 60 has transmitted PDCCH signaling and the confirmation device 60 has successfully received the uplink data. And in the scenario of coverage extension, PDCCH signaling is repeatedly transmitted. However, in this embodiment, the confirmation device 60 does not need to send PDCCH signaling specifically to the terminal, but instead the terminal determines whether the first physical downlink control channel signaling has been received in the first pre- Detect within a set period, where the first physical downlink control channel signaling is used to instruct the terminal to retransmit previously transmitted uplink data. If the terminal detects the first physical downlink control channel signaling within the first preset period, the terminal determines that the verification device 60 has not successfully received the uplink data, ie, uplink data Confirms that is not transmitted normally, the terminal retransmits the previously transmitted uplink data to the confirmation device 60 according to the first physical downlink control channel signaling.

And a processor 31 configured to determine in accordance with the detection result whether or not the uplink data has been successfully transmitted.

  Specifically, the confirmation device 70 knows the uplink resources allocated to the confirmation device by the base station to transmit uplink data according to the scheduling by the base station, and the transceiver 30 can receive on these uplink resources. Uplink data is transmitted to the base station, where the uplink data herein may be non-Msg3 or Msg3.

Therefore, the confirmation device 80 needs to notify the terminal to allocate the corresponding resource to the terminal and transmit uplink data on such resource. That is, the transmitter 41 in the confirmation device 80 further transmits the second physical downlink control channel signaling to the terminal, where the second physical downlink control channel signaling transmits the uplink data to the terminal. Used to command.

  Based on the embodiment shown in FIG. 7, as a possible implementation of this embodiment of the present invention, this embodiment determines whether the uplink data was successfully transmitted when the uplink data is non-Msg3. Further, the present invention relates to a process of confirming by the terminal together with the confirmation device 80. Further, the first physical downlink control channel signaling is used to instruct the terminal to transmit uplink data. Specifically, the processor 40 does not transmit the first physical downlink control channel signaling to the terminal when the detection result indicates that the uplink data transmitted by the terminal has been received within the second preset period. So that the terminal is configured to determine that the uplink data has been successfully transmitted, or the detection result indicates that the uplink data transmitted by the terminal is second pre- If it is not received within the set time period, it instructs the transmitter 41 to send the first physical downlink control channel signaling to the terminal, which causes the terminal It is configured to determine that it has not been transmitted.

  Specifically, when the confirmation device 80 does not normally receive the uplink data transmitted by the terminal, in the present embodiment, the first physical down link used to instruct the terminal to retransmit the uplink data. Link control channel signaling is sent to the terminal, as is the prior art. However, if the confirmation device 80 normally receives the uplink data transmitted by the terminal, the prior art indicates that the confirmation device 80 has transmitted PDCCH signaling and the confirmation device 80 has successfully received the uplink data. And in the scenario of coverage extension, PDCCH signaling is repeatedly transmitted. However, in this embodiment, the confirmation device 80 does not need to specifically send PDCCH signaling to the terminal; instead, the terminal determines whether the first physical downlink control channel signaling has been received in the first pre- Detect within a set period, where the first physical downlink control channel signaling is used to instruct the terminal to retransmit previously transmitted uplink data. If the terminal detects the first physical downlink control channel signaling transmitted by the transmitter 41 within the first preset period, the terminal determines that the confirmation device 80 has not successfully received the uplink data. That is, confirming that the uplink data is not transmitted normally, the terminal retransmits the previously transmitted uplink data to the confirmation device 80 according to the first physical downlink control channel signaling. If the terminal has not detected the first physical downlink control channel signaling, the terminal determines that the confirmation device 80 has successfully received the uplink data, and in this case, the confirmation device 80 has PDCCH signaling or ePDCCH signaling. To the terminal to notify that the base station has successfully received the uplink data, thereby reducing the physical downlink control channel signaling overhead.

  According to the uplink data transmission confirmation device provided in this embodiment of the present invention, the processor of the confirmation device detects whether the non-Msg3 transmitted by the terminal is received, obtains the detection result, and obtains the first physical According to the detection result, whether or not to instruct the transmitter to transmit the downlink control channel signaling to the terminal, and if the uplink data is successfully received, the confirming device can control the physical downlink control There is no need to send channel signaling specifically, instead, the terminal itself checks whether uplink data has been successfully transmitted, thus reducing the physical downlink control channel signaling overhead.

  Based on the embodiment shown in FIG. 7, as another possible implementation of this embodiment of the present invention, this embodiment determines whether the uplink data was successfully transmitted when the uplink data is Msg3. This is related to the process of confirming the information together with the confirmation device 80 by the terminal. The transmitter of this embodiment may be shared as the transmitter 41 of the embodiment of FIG. However, note that if the uplink data is Msg3, transmitter 41 does not need to send the second physical downlink control channel signaling to the terminal (since Msg3 is scheduled using the RAR message) Should. Further, the first physical downlink control channel signaling is used to instruct the terminal to receive Msg4 transmitted by the base station. Further, the processor 40 is configured to transmit the first physical downlink control channel signaling to the terminal if the detection result is that the uplink data transmitted by the terminal is received within the second preset period. Instructs the transmitter 41 so that the terminal is configured to determine that the uplink data has been successfully transmitted or the detection result indicates that the uplink data transmitted by the terminal is in the second preset period The transmitter 41 is instructed not to transmit the first physical downlink control channel signaling to the terminal, which causes the terminal to transmit uplink data normally. Configured to determine that there was no.

  Specifically, in the random access response process, the confirmation device 80 generally does not need to perform scheduling using PDCCH signaling, but instead performs scheduling using a RAR message. Therefore, the terminal may access the confirmation device 80 at random.

  In this embodiment, when the confirmation device 80 normally receives the uplink data transmitted by the terminal, the transmitter 41 directly transmits the first physical downlink control channel signaling to the terminal, where the first physical downlink Downlink control channel signaling is used to instruct the terminal to receive Msg4 transmitted by the confirmation device 80 on the corresponding resource. That is, the terminal detects whether the first physical downlink control channel signaling has been received within the first preset period, and if the first physical downlink control channel signaling is detected, the confirmation device 80 is up. It is determined that the link data has been normally received. In this case, Msg4 transmitted by the terminal base station is received.

  If the confirmation device 80 has not successfully received the uplink data sent by the terminal, the confirmation device 80 does not send the first physical downlink control channel signaling to the terminal, instead, the terminal If the physical downlink control channel signaling has been received within the first preset period and if the first physical downlink control channel signaling has not been detected within the first preset period, the confirmation device 80 Is determined not to receive uplink data normally.

  Further, the second preset period is configured by the confirmation device 80 according to the coverage extension requirement level of the terminal, or the mapping relationship between the coverage extension requirement level predefined by the confirmation device 80 and the terminal and the second preset period According to the verification device 80.

  According to the uplink data transmission confirmation device provided in this embodiment of the present invention, the processor of the confirmation device detects whether Msg3 transmitted by the terminal is received and obtains the detection result, Determine whether to send the first physical downlink control channel signaling to the terminal according to the detection result, so that the terminal has successfully transmitted Msg3 using the first physical downlink control channel signaling You can check whether.
