[0034] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, but should not be construed as limiting the present disclosure.

[0035] In the NR mode, the terminal side can send an acknowledgement ACK message or a non-acknowledgement NACK message to the network device through the PUCCH signal, so that the network device can determine whether the terminal has received the relevant information sent by the network device. When the network device receives the non-acknowledgement NACK message, it will re-schedule the transmission of the PDSCH signal to the terminal to re-transmit the relevant information, that is, the transmitting device needs to obtain an indication from the peer device to achieve signal re-transmission.

[0036] For example Figure 1 As shown, when the terminal determines that there is an ACK / non-acknowledgement NACK message to be transmitted to the network device, the terminal will send a PUCCH signal to the network device, where the PUCCH signal carries the ACK / non-acknowledgement NACK message; after the network device receives the PUCCH signal, it calculates the PUCCH signal. If the calculation result indicates that there is a non-acknowledgement NACK message in the PUCCH signal, the network device will re-schedule the transmission of the PDSCH signal to the terminal.

[0037] In the solution of the above background art, the network device needs to obtain the indication information (i.e., the non-acknowledgment NACK information) of the terminal to retransmit the PDSCH signal, which will increase the power consumption of the terminal to a certain extent.

[0038] Therefore, to solve the problems existing in the related art, the present disclosure proposes a communication solution. The first device detects whether the first information and the second information exist in the first signal, and determines whether to send the first signal to the second device based on this, so that the second device decides whether to retransmit the second signal. This method enables the second device to independently schedule the retransmission behavior of the second signal, not only reducing the power consumption of the first device, but also effectively avoiding the waste of communication resources.

[0039] Figure 2 It is a schematic diagram of the architecture of a communication system shown according to an embodiment of the present disclosure. As Figure 2 shown, the communication system may include at least one of the first device 101 and the second device 102.

[0040] In some embodiments, the first device 101 may be a terminal, such as including at least one of a mobile phone, a wearable device, an Internet of Things device, an automobile with communication function, a smart automobile, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, and a wireless terminal device in smart home, but not limited thereto.

[0041] In an embodiment of the present disclosure, the first device may be a chip, and the chip includes a processing circuit, and the processing circuit may execute the method shown in the present disclosure.

[0042] In some embodiments, the second device 102 may be a network device, for example, a node or device that connects a terminal to a wireless network. The access network device may include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a NodeB (NB), a home NodeB (HNB), a home evolved NodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an Open Radio Access Network (OpenRAN), a Cloud Radio Access Network (Cloud RAN), a base station in other communication systems, and an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0043] Figure 3 The interaction diagram of a communication method provided by an embodiment of the present disclosure is as follows. Figure 3 As shown, the communication method may include the following steps.

[0044] Step 301, the first device 101 determines whether there is first information and second information in the first signal.

[0045] In some embodiments, the first signal may be used to carry the first information and the second information, where the first information is used to indicate that the first device 101 has not received the second signal sent by the second device 102 or has not successfully parsed a data packet from the second signal.

[0046] In some embodiments, the second signal is used by the second device 102 to send a data packet to the first device 101.

[0047] In some embodiments, the first signal is, for example, a Physical Uplink Control Channel (PUCCH) signal, and the second signal is, for example, a Physical Downlink Shared Channel (PDSCH) signal, etc.

[0048] In some embodiments, the first information includes a Negative Acknowledgement (NACK) message; the second information includes at least one of an Acknowledgement (ACK) message, Channel State Information (CSI), and a Scheduling Request (SR).

[0049] Among them, the ACK information is used to indicate that the first device 101 has successfully received the second signal sent by the second device 102 and has successfully parsed the data packet from the second signal; NACK is used to indicate that the first device 101 fails to successfully receive the second signal sent by the second device 102, or the first device 101 fails to successfully parse the data packet from the second signal; the channel state information CSI can be used to indicate the channel state of channels such as PDSCH; the scheduling request SR can be used to request the second device 102 to allocate uplink resources for the first device 101.

[0050] In some embodiments, the first device 101 can determine whether there is a first piece of information and a second piece of information in the first signal by detecting and calculating the first signal that the first device 101 is about to send, but it is not limited thereto. The present disclosure does not limit the method for confirming whether there is a first piece of information and a second piece of information in the first signal.

[0051] Step 302, in the case where there is a first piece of information and no second piece of information in the first signal, the first device 101 does not send the first signal to the second device 102.

[0052] In some embodiments, in the case where there is a first piece of information and no second piece of information in the first signal, that is, when the first signal is used to indicate to the second device 102 that the first device 101 has not received the second signal sent by the second device 102, or has not successfully parsed the data packet from the second signal, the first device 101 may not send the first signal to the second device 102.

[0053] Exemplarily, when the PUCCH signal that the first device 101 is about to send contains the unacknowledged NACK information and does not contain any one of the acknowledged ACK information, the channel state information CSI, and the scheduling request SR, the first device 101 may not send the first signal.

[0054] Step 303, in the case where the second device 102 does not receive the first signal sent by the first device 101 at a preset time point, the second device 102 retransmits the second signal to the first device 101.

[0055] In some embodiments, in the case where the second device 102 does not receive the first signal sent by the first device 101 at a preset time point, the second device 102 may default that the first device 101 has not received the second signal sent by the second device 102, or has not successfully parsed the data packet from the second signal. At this time, the second device 102 may retransmit the second signal to the first device 101, so that the second device 102 can achieve autonomous scheduling of the second signal without the need for the first device 101 to send indication information, thereby reducing the power consumption of the first device 101.

[0056] In some embodiments, the preset time point may be set periodically or aperiodically, and the present disclosure does not limit this.

[0057] It should be understood that when setting the preset time point, the time required for the first device 101 to parse the second signal should be referred to, so as to avoid the second device 102 determining that the first device 101 has not received the second signal sent by the second device or has not successfully parsed the data packet from the second signal when the first device 101 is still parsing the second signal, and then retransmitting the second signal to the first device 101.

[0058] For example, after 10 s when the second device 102 sends the PDSCH signal to the first device 101 and the second device 102 does not receive the PUCCH signal sent by the first device 101, the second device 102 retransmits the PDSCH signal to the first device 101.

[0059] Step 304, when there is no first information or there is second information in the first signal, the first device 101 sends the first signal to the second device 102.

[0060] In some embodiments, when there is no first information or there is second information in the first signal that the first device 101 is about to send, it indicates that the first device 101 has successfully received the second signal sent by the second device 102 and has successfully parsed the data packet from the second signal. At this time, the first device 101 can send the first signal to the second device 102 to indicate to the second device 102 that the first device 101 has successfully parsed the data packet in the second signal, and the second device 102 does not need to retransmit the second signal to avoid wasting the communication resources of the second device 102.

[0061] For example, when the first device 101 determines that there is no negative acknowledgment NACK information in the PUCCH signal to be sent, the first device 101 sends the PUCCH signal to the second device 102.

[0062] For example, when the first device 101 determines that the PUCCH signal to be sent has any one of the acknowledgment ACK information, the channel state information CSI, and the scheduling request SR, the first device 101 sends the PUCCH signal to the second device 102.

[0063] It should be understood that when the first signal contains the acknowledgment ACK information, it indicates that the first device 101 is about to inform the second device 102 that the first device 101 has successfully parsed the second signal sent by the second device 102. Therefore, the first signal can be sent to the second device 102.

[0064] When the first signal includes channel state information (CSI), since CSI can be used to indicate the channel state of channels such as PDSCH, in order for the second device 102 to obtain the state of each channel in a timely manner to facilitate subsequent signal transmission, the first signal can be sent to the second device 102 at this time;

[0065] When the first signal includes a scheduling request (SR), since SR can be used to request the second device 102 to allocate uplink resources for the first device 101, in order for the first device 101 to obtain uplink resources in a timely manner, the first signal can be sent to the second device 102 at this time.

[0066] In summary, according to the communication method proposed in the present disclosure, it includes: the first device 101 determines whether there is first information and second information in the first signal; in the case where there is first information and no second information in the first signal, the first signal is not sent to the second device 102; when the second device 102 does not receive the first signal sent by the first device 101 at a preset time point, the second signal is retransmitted to the first device 101; when there is no first information or there is second information in the first signal, the first device 101 sends the first signal to the second device 102. The method of the present disclosure enables the first device 101 to detect whether there is first information and second information in the first signal, and based on this, determines whether to send the first signal to the second device 102, so that the second device 102 decides whether to retransmit the second signal. This method enables the second device 102 to autonomously schedule the retransmission behavior of the second signal, not only reducing the power consumption of the first device 101, but also effectively avoiding waste of communication resources.
