As known to those of ordinary skill in the art, with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions proposed in the embodiments of the present disclosure are equally applicable to similar technical problems.

[0030] The following embodiments of the present disclosure can be applied to Figure 1 the communication system 100 shown in the figure, or some of the main bodies, but not limited thereto. Figure 1 The main bodies shown in the figure are illustrative. The communication system may include Figure 1 all or some of the main bodies in the figure, or may also include Figure 1 other main bodies outside the figure. The number and form of each main body are arbitrary. The connection relationship between each main body is illustrative. Each main body may or may not be connected, and its connection can be in any way, either directly connected or indirectly connected, either wired or wirelessly connected.

[0031] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems extended based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) and applied.

[0032] In the related art, if a network device determines that a terminal fails to successfully decode a Physical Downlink Shared Channel (PDSCH) based on the ACK information fed back by the terminal, the network device will continue to retransmit the PDSCH, and the terminal will continue to feed back ACK information to the network device. Since the terminal will continue to use the transmit power specified by the protocol to feed back ACK information during the process of continuously feeding back ACK information, in this way, since the terminal uses the transmit power specified by the protocol each time it feeds back ACK information, there is a high probability that the network device still cannot decode the information fed back by the terminal, resulting in low decoding accuracy of the information fed back by the network device for the terminal.

[0033] In the embodiments of the present disclosure, in order to solve the above technical problems, by receiving a Physical Downlink Shared Channel (PDSCH) and determining whether the PDSCH is a retransmitted PDSCH to obtain a reference result, determining a target transmit power according to the reference result, and using the target transmit power to send a first piece of information, where the first piece of information is used for the network device to determine whether the terminal correctly decodes the PDSCH. Thus, according to whether the received PDSCH is a retransmitted PDSCH, information can be fed back to the network device using a flexibly configured transmit power, and the network device can determine whether the terminal correctly decodes the PDSCH based on this information, thereby improving the decoding accuracy of the information fed back by the network device for the terminal.

[0034] In the embodiments of the present disclosure, the transmit power can also be referred to as the emission power.

[0035] The following describes the information sending method, apparatus, electronic device, terminal, chip, and storage medium of the embodiments of the present disclosure with reference to the accompanying drawings.

[0036] The information sending method provided in the embodiments of the present disclosure can be applied to a terminal without limitation.

[0037] Figure 2 It is a schematic flowchart of an information sending method provided by the embodiments of the present disclosure.

[0038] As Figure 2 shown, the information sending method includes:

[0039] Step S201: Receive a Physical Downlink Shared Channel (PDSCH).

[0040] Among them, the network device can send the PDSCH to the terminal, the terminal can receive the PDSCH, and after receiving the PDSCH, the terminal can decode the PDSCH.

[0041] Step S202: Determine whether the PDSCH is a retransmitted PDSCH to obtain a reference result.

[0042] Among them, the retransmitted PDSCH indicates that the PDSCH is repeatedly sent by the network device. If the network device repeatedly sends the same PDSCH, it means that the network device determines that the terminal has not correctly decoded the PDSCH. The network device's determination that the terminal has not correctly decoded the PDSCH includes two cases: one is that the terminal has indeed not correctly decoded the PDSCH, and the other is that the terminal has correctly decoded the PDSCH, but the network device has not correctly decoded the information fed back by the terminal.

[0043] In some embodiments, after receiving the PDSCH sent by the network device, the terminal may determine whether the PDSCH is a retransmitted PDSCH to obtain a reference result, which can be used to indicate that the PDSCH is a retransmitted PDSCH or indicate that the PDSCH is not a retransmitted PDSCH.

[0044] Step S203: Determine the target transmission power according to the reference result.

[0045] Among them, the target transmission power refers to the transmission power that can ensure the correct decoding of the information fed back by the terminal by the network device.

[0046] In some embodiments, the terminal may select an appropriate target transmission power with reference to whether the received PDSCH is a retransmitted PDSCH, and the selected target transmission power can be used to send the first information.

[0047] In some embodiments, the terminal may appropriately adjust the transmission power specified by the protocol according to the reference result and use the adjusted transmission power as the target transmission power.

[0048] In some embodiments, any possible power control method may be referred to to determine the target transmission power according to the reference result, or the communication process between the terminal and the network device may be modeled, and the target transmission power may be determined according to the modeling result, or any other possible method may be adopted to determine the target transmission power according to the reference result, which is not limited herein.

[0049] Step S204: Send the first information using the target transmission power, where the first information is used for the network device to determine whether the terminal has correctly decoded the PDSCH.

[0050] Among them, the first information is used for the network device to determine whether the terminal has correctly decoded the PDSCH.

[0051] After the above-mentioned target transmission power, the first information may be sent using the target transmission power.

[0052] In this embodiment, by receiving a Physical Downlink Shared Channel (PDSCH) and determining whether the PDSCH is a retransmitted PDSCH, a reference result is obtained. According to the reference result, a target transmission power is determined, and the first information is transmitted using the target transmission power, where the first information is used by the network device to determine whether the terminal correctly decodes the PDSCH. Thus, according to whether the received PDSCH is a retransmitted PDSCH, information can be fed back to the network device using a flexibly configured transmission power, and the network device can determine whether the terminal correctly decodes the PDSCH based on this information, thereby improving the decoding accuracy of the information fed back by the network device to the terminal.

[0053] Figure 3 It is a schematic flowchart of another information transmission method provided by an embodiment of the present disclosure.

[0054] As Figure 3 shown, the information transmission method includes:

[0055] Step S301: Receive a Physical Downlink Shared Channel (PDSCH).

[0056] For the description of step S301, reference can be specifically made to the above embodiment, which will not be elaborated here.

[0057] Step S302: Determine a first Hybrid Automatic Repeat reQuest (HARQ) identifier associated with the PDSCH.

[0058] Among them, the HARQ identifier is usually used in a wireless communication system to identify and track the status and related information of each HARQ process. The PDSCH can be transmitted based on the HARQ process. If the PDSCHs transmitted by two HARQ processes with the same HARQ identifier are both transmitted, then the PDSCHs transmitted in these two HARQ processes are retransmitted PDSCHs. Thus, in the embodiment of the present disclosure, the Hybrid Automatic Repeat reQuest (HARQ) identifier associated with the currently received PDSCH can be used to analyze whether the currently received PDSCH is a retransmitted PDSCH.

[0059] Among them, the HARQ identifier associated with the currently received PDSCH can be referred to as the first HARQ identifier. This HARQ identifier can be used to uniquely identify the currently transmitted PDSCH.

[0060] Step S303: Obtain a second HARQ identifier associated with the previously received PDSCH.

[0061] In some embodiments, the HARQ identifier associated with the previously received PDSCH can be referred to as the second HARQ identifier.

[0062] Step S304: Determine whether the PDSCH is a retransmitted PDSCH according to the first HARQ identifier and the second HARQ identifier.

[0063] In the embodiments of the present disclosure, the first HARQ identifier associated with the currently received PDSCH and the second HARQ identifier associated with the previously received PDSCH can be compared and analyzed to determine whether the currently received PDSCH is a retransmitted PDSCH, thereby ensuring the determination efficiency and accuracy of the retransmitted PDSCH.

[0064] In some embodiments, in the process of implementing the determination of whether the PDSCH is a retransmitted PDSCH according to the first HARQ identifier and the second HARQ identifier, it can be determined that the PDSCH is a retransmitted PDSCH when the first HARQ identifier and the second HARQ identifier are the same, or it can be determined that the PDSCH is not a retransmitted PDSCH when the first HARQ identifier and the second HARQ identifier are different, thereby effectively and accurately determining whether the currently received PDSCH is a retransmitted PDSCH.

[0065] Step S305: Determine the target transmission power according to the reference result.

[0066] Step S306: Transmit the first information using the target transmission power, where the first information is used for the network device to determine whether the terminal correctly decodes the PDSCH.

[0067] For the descriptions of steps S305 - S306, reference can be specifically made to the above embodiments, which will not be elaborated here.

[0068] In this embodiment, by receiving the physical downlink shared channel PDSCH, determining whether the PDSCH is a retransmitted PDSCH, obtaining a reference result, determining the target transmission power according to the reference result, and transmitting the first information using the target transmission power, where the first information is used for the network device to determine whether the terminal correctly decodes the PDSCH. Thus, according to whether the received PDSCH is a retransmitted PDSCH, information can be fed back to the network device using a flexibly configured transmission power, and the network device can determine whether the terminal correctly decodes the PDSCH based on this information, thereby improving the decoding accuracy of the network device for the terminal feedback information. The first HARQ identifier associated with the currently received PDSCH and the second HARQ identifier associated with the previously received PDSCH can be compared and analyzed to determine whether the currently received PDSCH is a retransmitted PDSCH, thereby ensuring the determination efficiency and accuracy of the retransmitted PDSCH.

[0069] Figure 4Schematic flowchart of another information sending method provided by an embodiment of the present disclosure.

[0070] As Figure 4 shown, the information sending method includes:

[0071] Step S401: Receive a Physical Downlink Shared Channel (PDSCH).

[0072] Step S402: Determine whether the PDSCH is a retransmitted PDSCH to obtain a reference result.

[0073] For the descriptions of steps S401 - S402, reference can be specifically made to the above embodiments and will not be elaborated here.

[0074] Step S403: When the reference result indicates that the PDSCH is a retransmitted PDSCH, process the set transmission power to obtain a target transmission power.

[0075] That is to say, if it is determined that the PDSCH is a retransmitted PDSCH, the set transmission power specified by the protocol can be adjusted accordingly to obtain the target transmission power.

[0076] In some embodiments, in the process of implementing the processing of the set transmission power to obtain the target transmission power, the set transmission power can be increased to obtain the target transmission power. That is to say, the set transmission power can be increased to obtain the target transmission power, so as to ensure to a large extent that the network device correctly decodes the information fed back by the terminal.

[0077] In some embodiments, in the process of implementing the processing of the set transmission power to obtain the target transmission power, the sum value between the set transmission power and the target power value can be determined, and the sum value can be used as the target transmission power. Thus, the flexibility and effectiveness of the transmission power adjustment can be effectively improved, and it is supported for personalized communication scenarios.

[0078] In some embodiments, the target power value is greater than 0 dBm and less than or equal to 2 dBm. When feeding back information based on the adjusted target transmission power, it can ensure to improve the probability of successful decoding of the information fed back by the network device by the terminal, and at the same time, it can effectively avoid interference caused by the transmission of the first information to the transmission of other information by the terminal.

[0079] Step S404: When the reference result indicates that the PDSCH is not a retransmitted PDSCH, use the set transmission power as the target transmission power.

[0080] That is to say, if it is determined that the PDSCH is not a retransmitted PDSCH, the set transmission power specified by the protocol can be directly used as the target transmission power. That is, there is no need to adjust the set transmission power specified by the protocol.

[0081] Step S405: Transmit the first information using the target transmission power, where the first information is used for the network device to determine whether the terminal correctly decodes the PDSCH.

[0082] For the description of step S405, reference can be specifically made to the above embodiments, which will not be elaborated here.

[0083] In this embodiment, by receiving the Physical Downlink Shared Channel (PDSCH) and determining whether the PDSCH is a retransmitted PDSCH, a reference result is obtained. According to the reference result, the target transmission power is determined, and the first information is transmitted using the target transmission power, where the first information is used for the network device to determine whether the terminal correctly decodes the PDSCH. Thus, according to whether the received PDSCH is a retransmitted PDSCH, information can be fed back to the network device using a flexibly configured transmission power. The network device can determine whether the terminal correctly decodes the PDSCH based on this information, thereby improving the decoding accuracy of the information fed back by the terminal to the network device. By processing the set transmission power to obtain the target transmission power when the reference result indicates that the PDSCH is a retransmitted PDSCH, or using the set transmission power as the target transmission power when the reference result indicates that the PDSCH is not a retransmitted PDSCH, excessive computing resources can be avoided. And in the process of implementing the processing of the set transmission power to obtain the target transmission power, the target transmission power can be obtained by increasing the set transmission power. Thus, it can be ensured to a large extent that the network device correctly decodes the information fed back by the terminal. Or in the process of implementing the processing of the set transmission power to obtain the target transmission power, the sum value between the set transmission power and the target power value can be determined and used as the target transmission power. Thus, the flexibility and effectiveness of the transmission power adjustment can be effectively improved, supporting personalized communication scenarios. In addition, since the target power value is greater than 0 dBm and less than or equal to 2 dBm. When feeding back information based on the adjusted target transmission power, while ensuring an increase in the probability of successful decoding of the information fed back by the terminal to the network device, it can also effectively avoid interference caused by the transmission of the first information to the transmission of other information by the terminal.

[0084] In some embodiments of the present disclosure, after parsing the currently received PDSCH and feeding back the first information, the terminal can save the first HARQ identifier associated with the PDSCH. This enables the first HARQ identifier to be used to determine whether the next received PDSCH is a retransmitted PDSCH, thereby supporting a significant improvement in the decoding success rate of the information fed back by the terminal to the network device.

[0085] An example for the above embodiments can be as follows:

[0086] As Figure 5 shown,Figure 5 This is an interaction schematic diagram in an embodiment of the present disclosure. Taking the network device as a base station and the HARQ identifier as Harqid A as an example, the base station can send relevant configuration information of ACK feedback to the terminal. After the terminal correctly decodes the PDSCH in the downlink, it will feedback the corresponding ACK information to the base station. After the ACK information is fed back, if the terminal receives a retransmission of the PDSCH with the same harqId (Harqid A), the transmission power will be increased by N dBm (decibel milliwatt) compared with the normal situation when sending the next ACK information, where 0 < N ≤ 2. When the terminal sends ACK information and the base station decodes the ACK information incorrectly, the base station will continue to schedule the PDSCH with the same harqId. At this time, increasing the transmission power of the ACK information sent by the terminal can increase the probability of correct decoding by the base station.
