[0067] To facilitate understanding, we first explain the terms referred to in this disclosure. 1. Downlink control information (DCI) The DCI is carried by the physical downlink control channel (PDCCH), and the DCI may include uplink and downlink data scheduling, hybrid automatic repeat request (HARQ) information, power control, etc. The PDCCH is a physical channel for carrying downlink scheduling information.

[0068] 2. Scramble Scrambling is a processing method of a digital signal, in which a scrambling code and an original signal are XORed to obtain a new signal. Usually, the role of scrambling an uplink physical channel is to distinguish different terminal devices, while scrambling a downlink channel can distinguish cells and channels. A scrambling code can be used to scramble and descramble an original signal. For example, a scrambling code can scramble downlink control information (DCI), or may be referred to as scrambling for a PDCCH. Scrambling a DCI may specifically refer to scrambling a cyclic redundancy check (CRC) field of the DCI. Accordingly, descrambling a received DCI by a terminal device specifically refers to the terminal device descrambling the CRC field of the DCI using a corresponding type of scrambling code to determine the format or type of the DCI, etc.

[0069] The scrambling code may include, but is not limited to, a cell radio network temporary identifier (C-RNTI), a temporary cell radio network temporary identifier (TC-RNTI) and a random access radio network temporary identifier (RA-RNTI).

[0070] a) C-RNTI and TC-RNTI When a terminal device is in a radio resource control connected (RRC-connected) state, it indicates that a C-RNTI has been assigned to the terminal device, and the terminal device must carry the C-RNTI when initiating a random access request to a network side device. When a terminal device is in an RRC idle state or an RRC inactive state, it indicates that a C-RNTI has not yet been assigned to the terminal device. When a terminal device requests an RRC connection, the network side device may assign a temporary C-RNTI to the terminal device in subsequent response information, which is recorded as a TC-RNTI. After the random access of the terminal device is successful, the TC-RNTI can be converted to a C-RNTI.

[0071] b) RA-RNTI In the random access process, the generation of the RA-RNTI is related to the time-frequency resource that the terminal device uses to transmit the preamble. For example, if terminal device A and terminal device B use the same random access channel time-frequency resource to initiate random access, the corresponding RA-RNTI is the same.

[0072] In order to better understand the feedback processing method and apparatus disclosed in the embodiments of the present disclosure, a communication system to which the embodiments of the present disclosure can be applied will first be described below.

[0080] In step S201, a control command transmitted from a network side device is received. In an embodiment of the present disclosure, a control command is used to indicate whether the scheduled data supports the function of HARQ feedback or not.

[0081] In step S202, it is determined whether the scheduled data supports a HARQ feedback function. In the embodiment of the present disclosure, the scheduled data is data scheduled after receiving a control command, or data scheduled by a control command.

[0082] For example, the terminal device receives a control command, and determines based on the control command whether data scheduling after receiving the control command supports a HARQ feedback function, or the terminal device analyzes the control command to obtain data that needs to be scheduled by the control command, and determines whether the data scheduled by the control command supports a HARQ feedback function.

[0083] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled data supports a HARQ feedback function based on the received control command, and then determine whether to enable the HARQ feedback function for the scheduled data, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0084] In the implementation of the present disclosure, the control command may be a scheduling command, so that the terminal device can further enable and / or disable a HARQ feedback function for current data scheduling according to the control command. As an example, refer to FIG. 3, which is a schematic flowchart of another feedback processing method provided by an embodiment of the present disclosure.

As shown in FIG. 3, the method may include, but is not limited to, the following steps S301 and S302.

[0085] In step S301, a control command sent from a network side device is received, and the control command includes a first physical layer control signaling.

[0088] As yet another example, a control command sent from a network side device is received, the control command including first physical layer control signaling instructing enabling and disabling of HARQ. In some embodiments of the present disclosure, the first physical layer control signaling may be DCI.

[0089] In step S302, determine based on the first physical layer control signaling whether the current data scheduling of the first physical layer control signaling supports a HARQ feedback function.

[0090] As an example, take the case where the first physical layer control signaling indicates enabling HARQ, after receiving the control command, the terminal device enables the HARQ feedback function for data scheduled by the control command.

[0091] As another example, take the first physical layer control signaling as an example to indicate disabling HARQ, and after receiving the control command, the terminal device disables the HARQ feedback function for the data scheduled by the control command.

[0092] As yet another example, take the first physical layer control signaling as an example to indicate enabling and disabling of HARQ, after receiving the control command, the terminal device enables a feedback function for the data HARQ scheduled by the control command, and disables the HARQ feedback function after the transmission of the data scheduled by the control command is completed.

[0093] Referring to Figure 4, Figure 4 is a schematic diagram of a hybrid automatic repeat feedback provided by an embodiment of the present disclosure. As shown in Figure 4, when the received control command includes information for enabling scheduling HARQ, the terminal device enables a HARQ feedback function to perform HARQ feedback. When the received control command includes information for disabling scheduling HARQ, the terminal device does not perform HARQ feedback and disables the HARQ feedback function. This avoids the problem of HARQ blocking caused by too many HARQ processes.

[0094] By implementing an embodiment of the present disclosure, the terminal device can determine, based on the first physical layer control signaling included in the received control command, whether the data that needs to be scheduled by the control command supports a HARQ feedback function, and then determine whether to enable the HARQ feedback function, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0095] In the implementation of the present disclosure, the control command may be a control command for instructing the enabling or disabling of HARQ and a period. Thereby, the terminal device can further enable or disable the HARQ feedback function within the period based on the control command. As an example, refer to FIG. 5, which is a schematic flowchart of another feedback processing method provided by an embodiment of the present disclosure. The feedback processing method includes a second physical layer control signaling, and the second physical layer control signaling is used to indicate the enabling or disabling of HARQ and the first period. As shown in FIG. 5, the method may include, but is not limited to, the following steps S501 and S502.

[0096] In step S501, a control command sent from a network side device is received, and the control command includes a second physical layer control signaling. In an embodiment of the present disclosure, the second physical layer control signaling is used to indicate the enabling or disabling of HARQ and the first time period, where the first time period is a time period for enabling or disabling HARQ indicated by the second physical layer control signaling.

[0097] As an example, a control command sent from a network side device is received, the control command includes second physical layer control signaling, and the second physical layer control signaling is used to instruct enabling HARQ within a first period.

[0098] As another example, the control instruction includes second physical layer control signaling, and the second physical layer control signaling is used to instruct disabling HARQ within the first period of time.

[0099] In step S502, determine whether the data scheduling in the first period supports a HARQ feedback function according to the second physical layer control signaling.

[0100] As an example, taking the second physical layer control signaling as an indication of enabling HARQ, the terminal device enables the HARQ feedback function within a first period of time after receiving the control command.

[0101] As another example, taking the second physical layer control signaling as an example to indicate disabling HARQ, the terminal device disables the HARQ feedback function within a first period of time after receiving the control command.

[0102] By implementing an embodiment of the present disclosure, the terminal device can enable or disable HARQ within a first period based on a control command included in the second physical layer control signaling, thereby avoiding too many HARQ processes, preventing a decrease in the effectiveness of data transmission caused by insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0103] In the implementation of the present disclosure, the control command may be a control command for instructing the enabling or disabling of HARQ. Thus, the terminal device can directly enable or disable the HARQ feedback function based on the control command. Referring to FIG. 6, FIG. 6 is a schematic flowchart of another feedback processing method provided by an embodiment of the present disclosure. The feedback processing method includes a third physical layer control signaling, and the third physical layer control signaling is used to instruct the enabling or disabling of HARQ. As shown in FIG. 6, the method may include, but is not limited to, the following steps S601 and S602.

[0104] In step S601, a control command sent from a network side device is received, and the control command includes a third physical layer control signaling. In an embodiment of the present disclosure, a third physical layer control signaling is used to indicate enabling or disabling of HARQ.

[0105] As an example, a control command sent from a network side device is received, and the control command includes a third physical layer control signaling instructing the enabling of HARQ.

[0106] As another example, a control command sent from a network side device is received, the control command including a third physical layer control signaling instructing to disable HARQ.

[0107] In step S602, determine whether the data scheduling in the second period supports a HARQ feedback function according to a third physical layer control signaling.

[0108] The second period is a period from receiving a third physical layer control signaling for instructing enabling of HARQ to receiving a third physical layer control signaling for instructing disabling of HARQ, or the second period is a period from receiving a third physical layer control signaling for instructing disabling of HARQ to receiving a third physical layer control signaling for instructing enabling of HARQ.

[0109] As an example, refer to FIG. 7, which is a schematic diagram of another hybrid automatic repeat feedback provided by an embodiment of the present disclosure. As shown in FIG. 7, after the terminal device receives a control command including a third physical layer control signaling instructing HARQ to be enabled, the terminal device enables the HARQ feedback function until it receives a control command including a third physical layer control signaling instructing HARQ to be disabled. After the terminal device receives a control command including a third physical layer control signaling instructing HARQ to be disabled, the terminal device disables the HARQ feedback function until it receives a control command including a second physical layer control signaling instructing HARQ to be enabled.

[0110] In addition, the HARQ enable period shown in FIG. 7 indicates period information during which the terminal supports HARQ feedback. The period information can be instructed to the terminal device by the network side device via a predefined HARQ enabling pattern. The HARQ disable period shown in FIG. 7 indicates a period during which the terminal device disables the HARQ feedback function, and the HARQ enable period indicates a period during which the terminal device enables the HARQ feedback function, and the time length information of the above period can be instructed to the terminal device by the network side device via a predefined HARQ pattern. For example, the terminal device can receive a HARQ pattern transmitted from the network side device, and the HARQ pattern includes time information for enabling HARQ and / or time information for disabling HARQ. The time information for enabling HARQ is used to instruct the terminal device to enable the HARQ feedback function within one period, and the time information for enabling HARQ includes any one or more of a time start position, a time end position, and time length information, and indicates a specific period for which the terminal device enables the HARQ feedback function. The time information for disabling HARQ is used to instruct the terminal device to disable the HARQ feedback function within one period, and can also instruct the terminal device to enable the HARQ feedback function within other periods except the above-mentioned one period, and the time information for disabling HARQ includes any one or more of a time start position, a time end position, and time length information, and can also indicate a specific period for which the terminal device disables the HARQ feedback function.

[0111] By implementing an embodiment of the present disclosure, the terminal device can enable or disable HARQ based on the received control command including the second physical layer control, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing a decrease in the effectiveness of data transmission caused by insufficient HARQ processes in the terminal device, and improving the data transmission efficiency of the terminal device.

[0112] It should be noted that the feedback processing method in the embodiment of the present disclosure is applied to the scenarios of uplink transmission and downlink transmission of a terminal device. For the scenario of uplink transmission of a terminal device, in one implementation of the present disclosure, a control command for uplink transmission can be a control command, so that the terminal device can enable or disable a HARQ feedback function for scheduled uplink data based on the control command. As an example, refer to FIG. 8, which is a schematic flowchart of another feedback processing method provided by the embodiment of the present disclosure. The control command of the feedback processing method is a control command for uplink transmission. As shown in FIG. 8, the method may include, but is not limited to, the following steps S801 to S803.

[0113] In step S801, a control command sent from a network side device is received. In an embodiment of the present disclosure, the control command is a control command for uplink transmission. In the embodiments of the present disclosure, step S801 can be implemented in any one of the forms in each embodiment of the present disclosure, and the embodiments of the present disclosure are not limited thereto, and a repeated description will be omitted.

[0114] In step S802, it is determined according to the control command whether the scheduled data supports a HARQ feedback function. In the embodiment of the present disclosure, step S802 can be implemented in any one of the forms in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and a repeated description will be omitted.

[0115] In step S803, after the terminal device sends the uplink data, wait for a scheduling command or HARQ feedback further sent by the network side device, and determine whether to retransmit the uplink data according to the scheduling command or HARQ feedback further sent by the network side device, where the control command is a control command for downlink transmission and the scheduled data supports the HARQ feedback function, or clear a data cache in the HARQ process corresponding to the uplink data after the terminal device sends the uplink data, where the control command is a control command for downlink transmission and the scheduled data does not support the HARQ feedback function.

[0116] As an example, when the data scheduled by the control command for uplink transmission supports the HARQ feedback function, the terminal device waits for a scheduling command further transmitted by the network side device after transmitting the data scheduled by the control command for uplink transmission, and if the scheduling command further transmitted by the network side device indicates that the terminal device needs to retransmit the data scheduled by the uplink scheduling command, the terminal device needs to retransmit the data to the network side device. Or, if the scheduling command further transmitted by the network side device indicates that the terminal device does not need to retransmit the uplink data, the terminal device does not need to retransmit the data to the network side device.

[0117] As another example, if the data scheduled by the control command for uplink transmission supports a HARQ feedback function, the terminal device waits for HARQ feedback transmitted from the network side device after transmitting the data scheduled by the control command for uplink transmission, and if the HARQ feedback transmitted from the network side device indicates that the terminal device needs to retransmit the data scheduled by the control command for uplink transmission, the terminal device needs to retransmit the data to the network side device. Alternatively, if the HARQ feedback transmitted from the network side device indicates that the terminal device does not need to retransmit the data scheduled by the control command for uplink transmission, the terminal device does not need to retransmit the data to the network side device.

[0118] As yet another example, if the data of the control command for uplink transmission does not support the HARQ feedback function, after the terminal device transmits the data scheduled by the control command for uplink transmission, it clears the data cache in the HARQ process corresponding to the data.

[0119] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled uplink data supports a HARQ feedback function based on the received control command for uplink transmission, and if the scheduled data does not support the HARQ feedback function, clear the data cache in the HARQ process corresponding to the scheduled data, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0120] For a scenario of downlink transmission of a terminal device, in the implementation of the present disclosure, the control command for downlink transmission can be the control command, so that the terminal device can enable or disable the HARQ feedback function for scheduled downlink data according to the control command. As an example, refer to FIG. 9, which is a schematic flowchart of another feedback processing method provided by an embodiment of the present disclosure. The control command of the feedback processing method is a control command for downlink transmission. As shown in FIG. 9, the method may include, but is not limited to, the following steps S901 to S903.

[0121] In step S901, a control command sent from a network side device is received. In the embodiments of the present disclosure, step S901 can be implemented in any one of the forms in each embodiment of the present disclosure, and the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0122] In step S902, determine whether the scheduled data supports a HARQ feedback function according to the control command. In the embodiments of the present disclosure, step S902 can be implemented in any one of the forms in each embodiment of the present disclosure, and the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0123] In step S903, after the terminal device receives downlink data, feed back HARQ feedback information of the downlink data at a specified position, where the control command is a control command for downlink transmission and the scheduled data supports the HARQ feedback function; or, after the terminal device receives downlink data, disable HARQ feedback and clear a data cache in a HARQ process corresponding to the downlink data, where the control command is a control command for downlink transmission and the scheduled data does not support the HARQ feedback function.

[0124] As an example, if the data scheduled by the control command for downlink transmission supports a HARQ feedback function, after receiving the downlink data transmitted from the network side device, the terminal device feeds back HARQ feedback information of the received downlink data at a position indicated by the control command for downlink transmission.

[0125] As another example, if the data scheduled by the downlink scheduling command does not support the HARQ feedback function, after receiving the downlink data transmitted from the network side device, the terminal device invalidates its own HARQ feedback and clears the data cache in the HARQ process corresponding to the received downlink data.

[0126] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled downlink data supports a HARQ feedback function based on the received control command for downlink transmission, and if the scheduled data does not support the HARQ feedback function, clear the data cache in the HARQ process corresponding to the scheduled data, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0127] However, the disclosed embodiment can indicate whether the scheduled data supports the HARQ feedback function in an explicit manner. In some embodiments of the disclosed embodiment, the control command in the disclosed embodiment may include a predetermined information field, so that the terminal device can determine whether the scheduled data supports the HARQ feedback function according to the predetermined information field in the control command.

[0128] In an embodiment of the present disclosure, the length and / or location of a given information field is agreed upon by a protocol or the length and / or location of a given information field is pre-configured.

[0129] As an example, the length of a given information field and the location of a given information field may be agreed upon by a protocol. As another example, the length of a given information field and the location of a given information field may be preset.

[0130] As yet another example, the length of a given information field may be agreed upon by a protocol, or the location of a given information field may be preset. As yet another example, the length of a given information field may be preset and the location of a given information field may be agreed upon by a protocol.

[0131] It should be noted that in the embodiment of the present disclosure, the predetermined information field may be a new information field that has been introduced, or the predetermined information field may be an existing information field.

[0132] As an example, an information field called “HARQ disabling flag” can be introduced into the control command, where the information field has 1-bit length information, where “1” indicates that the scheduled data supports the HARQ feedback function, and “0” indicates that the scheduled data does not support the HARQ feedback function.

[0133] As another example, a value (e.g., RNTI value) in the corresponding information is carried as an indication target value through an existing information field in a control command (e.g., DCI) to indicate whether the scheduled data supports the HARQ feedback function. For example, if the indication value of a certain information field is a pre-agreed value, it is deemed that the scheduled data transmission supports the HARQ feedback function; if it is another value, it is deemed that the scheduled data transmission does not support the HARQ feedback function. A specific implementation of the above technical solution is shown in other embodiments and will not be described in detail here.

[0134] In addition, the embodiment of the present disclosure may indicate whether the scheduled data supports the HARQ feedback function in an implicit manner. In some embodiments of the present disclosure, the control command may be a scheduling command, and the scheduling command may be an existing communication command. In this way, the terminal device can acquire information on whether the scheduled data supports the HARQ feedback function in an implicit manner. For example, in the implementation of the present disclosure, whether the scheduled data supports the HARQ feedback function may be indicated by an RNTI (Radio Network Temporary Identity) value. As an example, referring to FIG. 10, FIG. 10 is a schematic flowchart of yet another feedback processing method provided by the embodiment of the present disclosure. The feedback processing method may set a correspondence relationship between the RNTI value and supporting the HARQ feedback function in advance, and thus the terminal device can determine whether the scheduled data supports the HARQ feedback function by the RNTI. As shown in FIG. 10, the method may include, but is not limited to, the following steps S1001 to S1004.

[0135] In step S1001, a scheduling command sent from a network side device is received, and the scheduling command includes an RNTI. In step S1002, a correspondence relationship between the RNTI value and whether or not the HARQ feedback function is supported is determined.

[0136] In the embodiment of the present disclosure, the network side device can notify the terminal device of the correspondence relationship between the RNTI value and supporting the HARQ feedback function in advance. Or, the network side device and the terminal device can agree on the correspondence relationship between the RNTI value and supporting the HARQ feedback function in advance.

[0137] For example, the RNTI value range can be divided into two parts, a first value range and a second value range, and the network side device can notify the terminal device in advance of the correspondence relationship between the RNTI value in the first value range and supporting the HARQ feedback function and the correspondence relationship between the RNTI value in the second value range and supporting the HARQ feedback function by communicating in advance. Alternatively, the network side device can agree in advance with the terminal device on the correspondence relationship between the RNTI value in the first value range and supporting the HARQ feedback function and the correspondence relationship between the RNTI value in the second value range and supporting the HARQ feedback function.

[0138] As an example, if the hexadecimal value of the RNTI value is expressed as 0001-003C, 0001-001E is a first value range, which corresponds to the scheduled data supporting the HARQ feedback function, and 001F-003C is a second value range, which corresponds to the scheduled data not supporting the HARQ feedback function. The network side device can notify the terminal device of the above correspondence in advance by performing proactive communication.

[0139] As another example, taking the hexadecimal value of the RNTI value as being represented as 0001-003C, the network side device may agree in advance with the terminal device that 0001-001E is a first value range, corresponding to the scheduled data supporting the HARQ feedback function, and 001F-003C is a second value range, corresponding to the scheduled data not supporting the HARQ feedback function.

[0140] In step S1003, the scheduling command is parsed to obtain the target RNTI value in the scheduling command. In step S1004, based on the corresponding relationship and the target RNTI value, determine whether the data scheduled by the control command supports a HARQ feedback function.

[0141] As an example, take the hexadecimal value range of RNTI as being represented as 0001-003C, 0001-001E is a first value range, corresponding to the scheduled data supporting the HARQ feedback function, and 001F-003C is a second value range, corresponding to the scheduled data not supporting the HARQ feedback function. If the target RNTI value is 0010, the target RNTI value is within the first value range, so that it can be determined that the scheduled data supports the HARQ feedback function by the control command.

[0142] By implementing an embodiment of the present disclosure, the terminal device can determine whether the scheduled data supports a HARQ feedback function based on the RNTI value in the received scheduling command, and then decide to enable or disable HARQ, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes in the terminal device, and improving the data transmission efficiency of the terminal device.

[0143] In some embodiments of the present disclosure, the terminal device can further determine whether the data scheduled by the control command supports the HARQ feedback function according to the scrambling sequence. As an example, refer to FIG. 11, which is a schematic flowchart of another feedback processing method provided by the embodiments of the present disclosure. The feedback processing method can set a correspondence relationship between the scrambling sequence and supporting the HARQ feedback function in advance, so that the terminal device can determine whether the data scheduled by the control command supports the HARQ feedback function according to the scrambling sequence. As shown in FIG. 11, the method may include, but is not limited to, the following steps S1101 to S1104.

[0144] In step S1101, a scheduling command sent from a network side device is received, and the scheduling command includes a scrambling sequence. In step S1102, a correspondence relationship between the scrambling sequence and whether or not the HARQ feedback function is supported is determined.

[0145] For example, two orthogonal scrambling sequences (e.g., a first scrambling sequence and a second scrambling sequence) may be predefined, and the presence of the first scrambling sequence is used to indicate that the scheduled data supports the HARQ feedback function, and the absence of the second scrambling sequence is used to indicate that the scheduled data does not support the HARQ feedback function.

[0146] In step S1103, the scheduling command is parsed to obtain the target scrambling sequence in the command. In step S1104, determine whether the data scheduled by the control command supports a HARQ feedback function based on the corresponding relationship and the target scrambling sequence.

[0147] As an example, taking the presence of the above-mentioned first scrambling sequence as an example to indicate that the scheduled data supports the HARQ feedback function, and the absence of the second scrambling sequence as an example to indicate that the scheduled data does not support the HARQ feedback function, if the scrambling sequence acquired by the terminal device includes the first scrambling sequence, the terminal device can determine that the scheduled data supports the HARQ feedback function, and if the scrambling sequence acquired by the terminal device includes the second scrambling sequence, the terminal device can determine that the scheduled data does not support the HARQ feedback function.

[0148] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled data supports a HARQ feedback function based on the scrambling sequence in the received scheduling command, and then decide to enable or disable HARQ, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the effectiveness of data transmission from being reduced due to insufficient HARQ processes of the terminal device, and improving the data transmission efficiency of the terminal device.

[0149] In the above embodiment of the present disclosure, the method provided by the embodiment of the present disclosure is described from the perspective of a terminal device. Hereinafter, the feedback processing method provided by the embodiment of the present disclosure will be further described from the perspective of a network side device.

[0150] Referring to Fig. 12, Fig. 12 is a schematic flowchart of a feedback processing method provided by an embodiment of the present disclosure. The method is executed by a network side device. As shown in Fig. 12, the method may include, but is not limited to, the following step S1201:

[0151] In step S1201, send a control command to a terminal device, where the control command is used to instruct the terminal device to determine whether the scheduled data supports a HARQ feedback function. The target scheduled data is data scheduled after the terminal device receives a control command, or is data scheduled by the control command.

[0152] For example, by sending a control command to a terminal device, the terminal device determines according to the control command whether the data scheduling after receiving the control command supports the HARQ feedback function; or, by sending a control command to a terminal device, the terminal device analyzes the control command to obtain the data that needs to be scheduled by the control command, and determines whether the data scheduled by the control command supports the HARQ feedback function.

[0153] In one implementation, the control command is a first physical layer control signaling including enabling and / or disabling HARQ, and the first physical layer control signaling is used to indicate whether the current data scheduling supports the HARQ feedback function or not.

[0154] As an example, a control command is sent to a terminal device, the control command including first physical layer control signaling, the first physical layer control signaling being used to instruct the terminal device to enable a HARQ feedback function for data scheduled by the control command.

[0155] As another example, a control command is sent to a terminal device, the control command including first physical layer control signaling, the first physical layer control signaling being used to instruct the terminal device to disable a HARQ feedback function for data scheduled by the control command.

[0156] As yet another example, a control command is sent to a terminal device, the control command including first physical layer control signaling, the first physical layer control signaling being used to instruct the terminal device to enable a HARQ feedback function for data scheduled by the control command, and to disable the HARQ feedback function after transmission of the data scheduled by the control command is completed.

[0157] In one implementation, the control instructions include second physical layer control signaling for indicating enabling or disabling HARQ and the first period, and the second physical layer control signaling is used to indicate whether data scheduling in the first period supports a HARQ feedback function or not.

[0158] As an example, a control command is sent to a terminal device, the control command including second physical layer control signaling, the second physical layer control signaling being used to instruct the terminal device to enable a HARQ feedback function within a first period after receiving the control command.

[0159] As another example, a control command is sent to a terminal device, the control command including second physical layer control signaling, the second physical layer control signaling being used to instruct the terminal device to disable the HARQ feedback function within a first period after receiving the control command.

[0160] In one implementation, the control instruction includes a third physical layer control signaling for instructing enabling or disabling of HARQ, the third physical layer control signaling is used to indicate whether data scheduling in the second period supports a HARQ feedback function or not, and the second period is a period from receiving the third physical layer control signaling for instructing enabling of HARQ to receiving the third physical layer control signaling for instructing disabling of HARQ, or the second period is a period from receiving the third physical layer control signaling for instructing disabling of HARQ to receiving the third physical layer control signaling for instructing enabling of HARQ.

[0161] As an example, a control command is sent to a terminal device, and the control command includes third physical layer control signaling, which is used to instruct the terminal device to disable HARQ after receiving the control command until a control command instructing the terminal device to enable HARQ is received.

[0162] As another example, a control command is sent to a terminal device, the control command including third physical layer control signaling, which is used to instruct the terminal device to enable HARQ after receiving the control command until a control command instructing the terminal device to disable HARQ is received.

[0163] In one implementation, the control command is a control command for an uplink transmission or a control command for a downlink transmission. For example, the terminal device may use a control command for uplink transmission as a control command to instruct the terminal device to determine whether the scheduled uplink data supports the HARQ feedback function, or may use a downlink scheduling control command as a control command to instruct the terminal device to determine whether the scheduled downlink data supports the HARQ feedback function.

[0164] In one implementation, the control command includes a predetermined information field, which is used to indicate whether the scheduled data supports a HARQ feedback function or not.

[0165] It should be noted that in the embodiment of the present disclosure, the predetermined information field may be a new information field that has been introduced, or the predetermined information field may be an existing information field.

[0166] As an example, the control command includes a newly introduced information field of "HARQ disabling flag", which has 1-bit length information, where "1" indicates that the scheduled data supports the HARQ feedback function, and "0" indicates that the scheduled data does not support the HARQ feedback function.

[0167] As another example, a value (e.g., an RNTI value) in some existing information fields can be used as an indication target value to indicate whether the scheduled data supports the HARQ feedback function. For example, if the indication value of a certain information field is a pre-agreed value, the scheduled data transmission is deemed to support the HARQ feedback function, and if it is another value, the scheduled data transmission is deemed to not support the HARQ feedback function. The specific implementation of the above technical solution may refer to other embodiments provided by the present disclosure, and detailed description is omitted in the present disclosure.

[0168] In one alternative implementation, the length and / or location of the predetermined information field is agreed upon by a protocol or the length and / or location of the predetermined information field is pre-set.

[0169] As an example, the length of a given information field and the location of a given information field may be agreed upon by a protocol. As another example, the length of a given information field and the location of a given information field may be preset.

[0170] As yet another example, the length of a given information field may be agreed upon by a protocol, or the location of a given information field may be preset. As yet another example, the length of a given information field may be preset and the location of a given information field may be agreed upon by a protocol.

[0171] By implementing an embodiment of the present disclosure, the network side device can instruct the terminal device through a control command to determine whether the scheduled data supports a HARQ feedback function, so that the terminal device can enable or disable HARQ, avoid having too many HARQ processes in the terminal device, prevent the effectiveness of data transmission from being reduced due to insufficient HARQ processes in the terminal device, and improve the data transmission efficiency of the terminal device.

[0172] In some implementations of the embodiment of the present disclosure, the control command sent from the network side device may be a scheduling command. For example, refer to FIG. 13, which is a schematic flowchart of another feedback processing method provided by the embodiment of the present disclosure. The method is performed by the network side device. As shown in FIG. 13, the method may include, but is not limited to, the following steps S1301 and S1302.

[0173] In step S1301, a control command is scrambled based on a target RNTI value, where the control command is a scheduling command.

[0174] For example, a target RNTI value is determined based on a correspondence between the RNTI value and whether or not the HARQ feedback function is supported, and a scheduling command is scrambled based on the target RNTI value, so that the scheduling command includes the target RNTI value.

[0175] As an example, take the hexadecimal value range of RNTI as being represented as 0001-003C, an RNTI value of 0001-001E is an RNTI value corresponding to the scheduled data supporting the HARQ feedback function, and an RNTI value of 001F-003C is an RNTI value corresponding to the scheduled data not supporting the HARQ feedback function. When the network side device needs to indicate to the terminal device that the scheduled data supports the HARQ feedback function, the network side device randomly selects one value (e.g., 0010) from 0001-001E as a target RNTI value, and scrambles the scheduling command according to the target RNTI value.

[0176] In step S1302, a scheduling command scrambled with the target RNTI value is sent to a terminal device. In an embodiment of the present disclosure, a scheduling command scrambled with a target RNTI value is used to implicitly indicate whether the scheduled data supports the HARQ feedback function or not.

[0177] By implementing an embodiment of the present disclosure, the network side device can instruct the terminal device to determine whether the scheduled data supports a HARQ feedback function via a target RNTI value in a control command, so that the terminal device can enable or disable HARQ, avoiding too many HARQ processes in the terminal device, preventing a decrease in the effectiveness of data transmission caused by insufficient HARQ processes in the terminal device, and improving the data transmission efficiency of the terminal device.

[0178] In some implementations of the embodiment of the present disclosure, the control command sent from the network side device may be a scheduling command. For example, refer to FIG. 14, which is a schematic flowchart of another feedback processing method provided by the embodiment of the present disclosure. The method is performed by the network side device. As shown in FIG. 14, the method may include, but is not limited to, the following steps S1401 and S1402.

[0179] In step S1401, a control command is scrambled using a target scrambling sequence on the RNTI, where the control command is a scheduling command.

[0180] For example, the network side device and the terminal device can predefine two orthogonal scrambling sequences, and the existence of the above scrambling sequences is used to indicate that the scheduled data supports the HARQ feedback function, and the absence of the above orthogonal scrambling sequences is used to indicate that the scheduled data does not support the HARQ feedback function. When the network side device needs to indicate to the terminal device that the scheduled data supports the HARQ feedback function, it scrambles the scheduling command with the above orthogonal scrambling sequences on the RNTI, or when the network side device needs to indicate to the terminal device that the scheduled data supports the HARQ feedback function, it scrambles the scheduling command with another scrambling sequence different from the above orthogonal scrambling sequences on the RNTI.

[0181] In step S1402, a scheduling command scrambled with the target scrambling sequence is sent to a terminal device. In an embodiment of the present disclosure, the scheduling command scrambled with the target scrambling sequence is used to implicitly indicate whether the scheduled data supports the HARQ feedback function or not.

[0182] By implementing an embodiment of the present disclosure, the network side device can instruct the terminal device to determine whether the scheduled data supports a HARQ feedback function through a scrambling sequence in a control command, so that the terminal device can enable or disable HARQ, avoiding too many HARQ processes in the terminal device, preventing a decrease in the effectiveness of data transmission caused by insufficient HARQ processes in the terminal device, and improving the data transmission efficiency of the terminal device.
