[Means for solving the problem]

[0067] To facilitate understanding, we first explain the terms referred to in this disclosure. 1. Downlink control information (DCI) DCI is carried by the physical downlink control channel (PDCCH), and 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 digital signal processing method in which a new signal is obtained by performing an exclusive OR operation on a scrambling code and the original signal. Typically, the purpose of uplink physical channel scrambling is to distinguish between different terminal devices, while downlink scrambling can distinguish between cells and channels. A scrambling code can be used to scramble and descramble the original signal. For example, a scrambling code can scramble downlink control information (DCI), or may be referred to as scrambling for a PDCCH. Scrambling DCI specifically refers to scrambling the cyclic redundancy check (CRC) field of the DCI. Accordingly, descrambling the 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.

[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 the TC-RNTI. After the terminal device's random access 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 used by the terminal device 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] 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 are applicable will first be described below.

[0073] Referring to Figure 1, Figure 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure.

[0078] The feedback processing method and device provided by the present disclosure will be described in detail below with reference to the drawings.

[0079] Referring to Figure 2, Figure 2 is a schematic flowchart of a feedback processing method provided by an embodiment of the present disclosure. As shown in Figure 2, the feedback processing method may include, but is not limited to, the following steps S201 and S202.

[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.

[0081] In step S202, it is determined whether the scheduled data supports the 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 the 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 the HARQ feedback function.

[0083] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled data supports the 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 in the terminal device, and improving the data transmission efficiency of the terminal device.

[0084] In an implementation of the present disclosure, the control command may be a scheduling command, which allows the terminal device to further enable and / or disable a HARQ feedback function for current data scheduling based on the control command. For example, refer to FIG. 3, 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 includes first physical layer control signaling, which is used to instruct enabling and / or disabling of HARQ. 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. In an embodiment of the present disclosure, the first physical layer control signaling is used to indicate enabling and / or disabling of HARQ.

[0086] As an example, a control command sent from a network side device is received, and the control command includes first physical layer control signaling instructing to enable HARQ.

[0087] As another example, a control command sent from a network side device is received, and the control command includes first physical layer control signaling instructing to disable HARQ.

[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, when the first physical layer control signaling indicates enabling HARQ, after receiving the control command, the terminal device enables the HARQ feedback function for the data scheduled by the control command.

[0091] As another example, if the first physical layer control signaling indicates disabling of HARQ, after receiving the control command, the terminal device disables the HARQ feedback function for the data scheduled by the control command.

[0092] As another example, take the first physical layer control signaling as an example to instruct 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 hybrid automatic repeat feedback provided by an embodiment of the present disclosure. As shown in Figure 4, if the received control command includes information enabling scheduling HARQ, the terminal device enables the HARQ feedback function and performs HARQ feedback. If the received control command includes information disabling scheduling HARQ, the terminal device does not perform HARQ feedback and disables the HARQ feedback function. This avoids HARQ blocking problems caused by too many HARQ processes.

[0094] By implementing the embodiments 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 the 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 in the terminal device, and improving the data transmission efficiency of the terminal device.

[0095] In an implementation of the present disclosure, the control command may be a control command for instructing HARQ enablement or disablement and a time period. This allows the terminal device to further enable or disable the HARQ feedback function within the time period based on the control command. For 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 second physical layer control signaling, which is used to instruct HARQ enablement or disablement and the first time 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 second physical layer control signaling. In an embodiment of the present disclosure, the second physical layer control signaling is used to indicate whether HARQ is enabled or disabled and the first period, which is the 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, and 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.

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

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

[0101] As another example, if the second physical layer control signaling instructs disabling HARQ, the terminal device disables the HARQ feedback function within a first period after receiving the control command.

[0102] By implementing an embodiment of the present disclosure, the terminal device can enable or disable HARQ within the 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 due to insufficient HARQ processes in the terminal device, and improving the data transmission efficiency of the terminal device.

[0103] In an embodiment 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, which 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 whether HARQ is enabled or disabled.

[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 to enable HARQ.

[0106] As another example, a control command sent from a network side device is received, and the control command includes 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 the third physical layer control signaling.

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

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

[0110] Note that the HARQ enable period shown in FIG. 7 represents information about a period during which a terminal supports HARQ feedback. The period information can be instructed to a terminal device by a network side device via a predefined HARQ enabling pattern. The HARQ disable period shown in FIG. 7 represents a period during which a terminal device disables the HARQ feedback function, and the HARQ enable period represents a period during which a terminal device enables the HARQ feedback function. Time length information about the above periods can be instructed to a terminal device by a network side device via a predefined HARQ pattern. For example, the terminal device can receive an 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 a terminal device to enable the HARQ feedback function within a 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 during which the terminal device enables the HARQ feedback function. The time information for disabling HARQ is used to instruct a terminal device to disable the HARQ feedback function within a period, and can also instruct the terminal device to enable the HARQ feedback function within other periods except the 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 during 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. Regarding 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, whereby the terminal device can enable or disable the 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 the HARQ feedback function. In the embodiments of the present disclosure, step S802 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 repetitive 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 after the terminal device sends the uplink data, clear a data cache in the HARQ process corresponding to 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] For example, if the data scheduled by the control command for uplink transmission supports the HARQ feedback function, after transmitting the data scheduled by the control command for uplink transmission, the terminal device waits for a scheduling command further transmitted by the network side device, 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. Alternatively, 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 transmitting the data scheduled by the control command for uplink transmission, the terminal device clears the data cache in the HARQ process corresponding to the data.

[0119] By implementing the embodiments of the present disclosure, the terminal device determines whether the scheduled uplink data supports the HARQ feedback function based on the received control command for uplink transmission. If the scheduled data does not support the HARQ feedback function, the terminal device can clear the data cache of the HARQ process corresponding to the scheduled data. This can avoid the problem of HARQ blocking caused by too many HARQ processes, 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.

[0120] For a scenario of downlink transmission of a terminal device, in an implementation of the present disclosure, a control command for downlink transmission can be a control command, so that the terminal device can enable or disable a HARQ feedback function for scheduled downlink data based on the control command. For 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, it is determined according to the control command whether the scheduled data supports the HARQ feedback function. 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 the downlink data, it feeds 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 the downlink data, it disables HARQ feedback and clears a data cache in the 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, based on the received control command for downlink transmission, whether the scheduled downlink data supports the HARQ feedback function. If the scheduled data does not support the HARQ feedback function, the terminal device can clear the data cache of the HARQ process corresponding to the scheduled data. This can avoid the problem of HARQ blocking caused by too many HARQ processes, 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.

[0127] In addition, the disclosed embodiments may explicitly indicate whether the scheduled data supports the HARQ feedback function. In some embodiments of the disclosed embodiments, the control command may include a predetermined information field, so that the terminal device can determine whether the scheduled data supports the HARQ feedback function based on the predetermined information field in the control command.

[0128] In embodiments 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 preset.

[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 predetermined. As yet another example, the length of a given information field may be preset, or 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, and 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, an existing information field in a control command (e.g., DCI) may carry a value (e.g., an RNTI value) in the corresponding information 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, it is considered that the scheduled data transmission supports the HARQ feedback function; if it is another value, it is considered that the scheduled data transmission does not support the HARQ feedback function. Specific implementations of the above technical solutions are described in other embodiments and will not be described in detail here.

[0134] It should be noted that embodiments 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. This allows the terminal device to implicitly obtain information on whether the scheduled data supports the HARQ feedback function. For example, in an 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, refer to FIG. 10, which is a schematic flowchart of yet another feedback processing method provided by embodiments of the present disclosure. The feedback processing method may pre-configure a correspondence relationship between the RNTI value and support for the HARQ feedback function, thereby allowing the terminal device to determine whether the scheduled data supports the HARQ feedback function based on 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, the correspondence between the RNTI value and whether the HARQ feedback function is supported is determined.

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

[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 a correspondence relationship between the RNTI value in the first value range and support for the HARQ feedback function, and a correspondence relationship between the RNTI value in the second value range and support for the HARQ feedback function, through proactive communication. Alternatively, the network side device can agree in advance with the terminal device on a correspondence relationship between the RNTI value in the first value range and support for the HARQ feedback function, and a correspondence relationship between the RNTI value in the second value range and support for the HARQ feedback function.

[0138] As an example, if the hexadecimal number 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 proactive communication.

[0139] As another example, taking the hexadecimal value of the RNTI value as 0001-003C, the network side device can agree in advance with the terminal device that 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.

[0140] In step S1003, the scheduling command is parsed to obtain the target RNTI value in the scheduling command. In step S1004, it is determined whether the data scheduled by the control command supports the HARQ feedback function according to the correspondence relationship and the target RNTI value.

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

[0142] By implementing the embodiments of the present disclosure, the terminal device can determine whether the scheduled data supports the HARQ feedback function based on the RNTI value in the received scheduling command, and then determine whether to enable or disable HARQ, thereby avoiding the problem of HARQ blocking caused by too many HARQ processes, preventing the reduction 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.

[0143] In some embodiments of the present disclosure, the terminal device may further determine, based on the scrambling sequence, whether the data scheduled by the control command supports the HARQ feedback function. For example, refer to FIG. 11, which is a schematic flowchart of another feedback processing method provided by an embodiment of the present disclosure. The feedback processing method may pre-set a correspondence between the scrambling sequence and support for the HARQ feedback function, thereby allowing the terminal device to determine, based on the scrambling sequence, whether the data scheduled by the control command supports the HARQ feedback function. 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, the correspondence between the scrambling sequence and whether 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 instruction is parsed to obtain the target scrambling sequence in the instruction. In step S1104, it is determined whether the data scheduled by the control command supports the HARQ feedback function according to 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 determine whether 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.

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

[0150] 12, which is a schematic flowchart of a feedback processing method provided by an embodiment of the present disclosure. The method is performed 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 data scheduled by a control command.

[0152] For example, by sending a control command to a terminal device, the terminal device determines, based on the control command, whether 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 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.

[0154] As an example, a control command is sent to a terminal device, and the control command includes first physical layer control signaling, which is 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 includes first physical layer control signaling, and the first physical layer control signaling is 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 includes first physical layer control signaling, and the first physical layer control signaling is 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 HARQ feedback functionality.

[0158] As an example, a control command is sent to a terminal device, and the control command includes second physical layer control signaling, which is 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 command includes third physical layer control signaling for instructing enabling or disabling of HARQ, and the third physical layer control signaling is used to instruct whether data scheduling in the second period supports an HARQ feedback function, 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 it receives a control command instructing the terminal device to enable HARQ.

[0162] As another 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 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.

[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 in some existing information fields (e.g., an RNTI value) 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. Specific implementations of the above technical solutions may refer to other embodiments provided by the present disclosure, and detailed descriptions thereof will be 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 preset.

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

[0171] By implementing the embodiments 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, thereby allowing the terminal device to enable or disable HARQ, avoiding the terminal device having too many HARQ processes, preventing the terminal device from having insufficient HARQ processes, thereby improving the data transmission efficiency of the terminal device.

[0172] In some implementations of the embodiments 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 embodiments 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, and the control command is a scheduling command.

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

[0175] As an example, if the hexadecimal value range of RNTI is represented as 0001 to 003C, an RNTI value of 0001 to 001E is the RNTI value corresponding to the scheduled data supporting the HARQ feedback function, and an RNTI value of 001F to 003C is the 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 to 001E as a target RNTI value, and scrambles the scheduling command based on the target RNTI value.

[0176] In step S1302, a scheduling command scrambled with the target RNTI value is sent to the 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.
