Optionally, the higher layer parameter or the higher layer signaling in the embodiment of the present application includes at least one of Radio Resource Control (RRC) signaling and Media Access Control Element (MAC CE).

For better understanding of the embodiments of the present application, the HARQ mechanism and HARQ-ACK feedback mechanism related to the present application will be described first.

HARQ mechanism in NR systems

There are two levels of retransmission mechanisms in NR systems: a HARQ mechanism of a Media Access Control (MAC) layer and an Automatic Repeat reQuest (ARQ) mechanism of a Radio Link Control (RLC) layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, the initiator stops to wait for an acknowledgement after transmitting a Transport Block (TB) once. Thus, the sender may stop after each transmission and wait for an acknowledgement, which may result in low user throughput. Therefore, NR uses a plurality of parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing for continuous transmission of data. HARQ is divided into uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission and downlink HARQ is for downlink data transmission. The two are independent of each other.

In some cases, the terminal device has a separate HARQ entity for each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. As an example, each uplink and downlink carrier supports a maximum of 16 HARQ processes. The network device may indicate the maximum number of HARQ processes to the terminal device through RRC signaling semi-static configuration according to the network device deployment condition. Optionally, in some embodiments, if the network device does not provide the corresponding configuration parameter, the downlink default number of HARQ processes is 8, and the maximum number of HARQ processes supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process ID. For downlink, a Broadcast Control Channel (BCCH) uses a dedicated Broadcast HARQ process. For uplink, message 3 (Msg 3) transmission in the random procedure uses HARQ ID 0.

In some embodiments, for a terminal device that does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at the same time; for a terminal device supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal device processes 1 TB simultaneously.

HARQ is classified into two types, synchronous and asynchronous, in the time domain, and non-adaptive and adaptive, in the frequency domain. The NR uplink and downlink use asynchronous adaptive HARQ mechanisms. For asynchronous HARQ, the time interval between the retransmission of the same TB and the last transmission is not fixed. The adaptive HARQ may change the frequency domain resource and the Modulation and Coding Scheme (MCS) used for the retransmission.

With reference to fig. 2, the following transmission example will describe the relationship between the number of HARQ processes supported and the Round Trip Time (RTT). As shown in fig. 2, the maximum number of HARQ processes configured for the terminal device is 16, and then when the RTT is small, for example, less than 16ms, the maximum throughput of the terminal device is not affected, or if the RTT is less than 16ms, when there is traffic to be transmitted, the terminal device may always have parallel HARQ processes for data transmission. Of course, if the RTT is large, for example, much greater than 16ms, all HARQ processes of the terminal device may be used for data transmission, and the feedback of the network device is not obtained, so that the terminal device has a service to be transmitted but no HARQ process can be used, and throughput of data transmission at the terminal device side may be affected.

HARQ-ACK feedback in NR systems

For a terminal device with Downlink traffic, the network device may schedule transmission of a Physical Downlink Shared Channel (PDSCH), that is, downlink transmission, for the terminal device through the DCI. The DCI includes indication information of a Physical Uplink Control Channel (PUCCH) resource, and after receiving the PDSCH, the terminal device feeds back a decoding result (acknowledgement (ACK) information or Negative Acknowledgement (NACK) information) of the PDSCH to the network device through the PUCCH resource. Wherein dynamic determination of HARQ feedback timing is supported in an NR system. The network device is used for scheduling the terminal device to receive the PDSCH through DCI, where the DCI includes indication information of an uplink feedback resource, for example, a PUCCH resource, used for transmitting the HARQ-ACK corresponding to the PDSCH.

In the NTN system, the RTT of signal transmission is large due to the long communication distance between the terminal device and the satellite (or the network device). In GEO systems, the RTT of the signaling may be on the order of hundreds of milliseconds, for example, the RTT of the signaling may be at most about 600ms. In LEO systems, the RTT of the signaling may be on the order of tens of milliseconds. Since RTT of the NTN system is much larger than RTT of the terrestrial communication system, the HARQ mechanism in the NR system is not suitable for the NTN system.

As a solution: configuring HARQ processes to disable

Taking downlink transmission as an example, the network device may configure de-enabling for at least one downlink HARQ process of the terminal device. For the downlink HARQ process configured to be disabled, the network device can reuse the HARQ process for data transmission without receiving HARQ-ACK information corresponding to feedback of the terminal device for the TB transmitted in the HARQ process. Therefore, the network device can use the disabled HARQ process to schedule a plurality of data packets for the terminal device, thereby reducing the influence of RTT.

As another solution: increasing the number of HARQ processes

Within the range allowed by the terminal device capability, the number of HARQ processes configured for the terminal device by the network device may exceed the maximum number of HARQ processes supported by the NR system. For example, the number of HARQ processes configured by the network device for the terminal device may exceed 16. The increase of the number of HARQ processes indicates that data packets that can be transmitted in parallel between the network device and the terminal device increase, so that the influence caused by RTT can be reduced.

Under the condition of configuring the HARQ process to disable, when the terminal device receives the downlink transmission scheduled by the HARQ process for disabling the HARQ-ACK feedback, the terminal device may not perform HARQ-ACK feedback for the downlink transmission. When the terminal device receives the downlink transmission scheduled by the HARQ process enabling HARQ-ACK feedback, the terminal device needs to perform HARQ-ACK feedback for the downlink transmission.

As described above, DCI can be used to schedule downlink transmission or uplink transmission on an HARQ process at present, however, when there are the above two types of HARQ processes, how to schedule downlink transmission or uplink transmission on the HARQ process is a technical problem to be solved in the present application.

Fig. 3 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application, and as shown in fig. 3, the method 300 may include at least some of the following:

step S310: the network device transmits the first DCI to the terminal device.

Step S320a: and the terminal equipment receives the first physical channel through the first HARQ process according to the first DCI. Alternatively, the first and second electrodes may be,

step S320b: and the terminal equipment transmits the first physical channel through the first HARQ process according to the first DCI.

The first DCI is used for scheduling the terminal device to transmit a first physical channel through a first HARQ process, where the first DCI corresponds to a first DCI format and the first HARQ process corresponds to a non-enabled state, or the first DCI corresponds to a second DCI format and the first HARQ process corresponds to an enabled state.

Optionally, the present embodiment is applicable to a downlink transmission scenario and is also applicable to an uplink transmission scenario. In a downlink transmission scenario, the first DCI includes downlink allocation information, where the downlink allocation information is used to schedule a first physical channel, and the first physical channel is a downlink physical channel. In an uplink transmission scenario, the first DCI includes uplink grant information, where the uplink allocation information is used to schedule a first physical channel, and the first physical channel is an uplink physical channel.

In the embodiment of the present application, the state of the HARQ process may include an enabled state and a disabled state. Alternatively, as the standard evolves, more states may be included, such as a half-enable state, and the like, and the present application is not limited thereto.

Optionally, in this embodiment of the present application, each HARQ process has a corresponding state, where the state corresponding to the HARQ process may also be expressed as a state of the HARQ process, or as whether the HARQ process is configured to be in an enabled state or a non-enabled state.

From the perspective of HARQ-ACK feedback, the state of the HARQ process is enabled or disabled, and may also be expressed as the HARQ feedback function state corresponding to the HARQ process may be enabled or disabled. In other words, the HARQ feedback function state corresponding to the HARQ process is configured to be enabled or disabled.

In the embodiments of the present application, the non-enabled state is also referred to as a disabled (disabled) state.

Optionally, in some embodiments, the state of the HARQ process may be configured by higher layer signaling, or may also be dynamically indicated by dynamic signaling, for example, DCI, or may also be implicitly determined, and the present application does not limit the configuration manner of the state of the HARQ process.

It should be understood that, when the present embodiment is applied to downlink transmission, the first HARQ process is a downlink HARQ process, and when the present embodiment is applied to uplink transmission, the first HARQ process is an uplink HARQ process.

Optionally, in some embodiments, the terminal device reports to the network device whether the terminal device supports the HARQ process disabling function.

Optionally, in some embodiments, the terminal device is configured by the network device to support HARQ process de-enabling through higher layer parameters.

Optionally, when the first HARQ process is a downlink HARQ process, the first HARQ process corresponds to a non-enabled state, that is, the downlink HARQ process corresponds to a non-enabled state, where the method includes at least one of the following cases:

after receiving the downlink transmission through the downlink HARQ process, the terminal equipment does not need to send HARQ-ACK information corresponding to the downlink transmission to the network equipment.

The DCI of the second DCI format includes an HARQ process number information field that is an information field indicating an enabled HARQ process number. For another example: the DCI of the first DCI format does not include a Redundancy Version (RV) information field, and the DCI of the second DCI format includes an RV information field.

Optionally, the smaller the index value of the MCS is, the less the number of transmissions of the TB corresponding to the first HARQ process indicated by the retransmission number indication information corresponding to the MCS is; the larger the index value of the MCS is, the more the number of transmissions of the TB corresponding to the first HARQ process indicated by the retransmission number indication information corresponding to the MCS is. By the method, the network equipment can ensure that the transmission can achieve the same or similar reliability under different MCS.

Optionally, the smaller the index value of the MCS is, the more the number of transmissions of the TB corresponding to the first HARQ process indicated by the retransmission number indication information corresponding to the MCS is. In this way, the network device increases the reliability of the transmission or enhances the coverage of the cell.

Wherein, the RV indication information is carried in the RV information domain in the DCI of the first DCI format. Therefore, the number of bits included in the RV indication information is also expressed as the size or length of the RV information field.

Optionally, the DCI of the first DCI format does not include RV indication information, that is, the size or length of the RV information field is 0, and an RV corresponding to TB transmission corresponding to the first HARQ process is preset or determined according to an RV pattern configured by the network device.

Optionally, if the transmission frequency of the TB corresponding to the first HARQ process is 1, the RV corresponding to the TB transmission corresponding to the first HARQ process is 0. Or, if the transmission frequency of the TB corresponding to the first HARQ process is K, the RV corresponding to the TB transmission corresponding to the first HARQ process is determined according to the RV pattern configured by the network device, and K is an integer greater than 1.

Wherein, the HARQ process number indication information is carried in the HARQ process number information field in the DCI of the second DCI format. Therefore, the number of bits included in the HARQ process number indication information is also expressed as the size or length of the HARQ process number information field.

Optionally, when the second number of HARQ processes is 0, the number of bits included in the HARQ process number indication information is 0, that is, the HARQ process number indication information is not included in the DCI of the second DCI format.

Optionally, the second number of HARQ processes is M, and the number of bits included in the HARQ process number indication information is according to ceil (log) ₂ (M)) the number of bits included as HARQ process number indication information is ceil (log) ₂ (M)), where M is a positive integer and ceil () represents a ceiling.

When M =1, the number of bits included in the HARQ process number indication information is 0, that is, the HARQ process number indication information is not included in the DCI of the second DCI format.

Optionally, when the DCI in the second DCI format does not include the HARQ process number indication information, the process number corresponding to the first HARQ process is preset or configured by the network device through the second high-level parameter. For example, the process number of the first HARQ process corresponding to the enabled state in the second higher layer parameter configuration is HARQ process 2, the DCI in the second DCI format does not include HARQ process number indication information, and when the terminal device receives the first physical channel scheduled by the second DCI format, the first physical channel is transmitted through HARQ process 2.

In summary, the embodiments of the present application provide a method for scheduling uplink transmission or downlink transmission on an HARQ process when there are HARQ processes in the enabled state and the disabled state. In addition, in this embodiment of the present application, the DCI in the first DCI format and the DCI in the second DCI format correspond to a non-enabled HARQ process and an enabled HARQ process, respectively, so that DCI information included in the DCI in the first DCI format is all for the non-enabled HARQ process and is not for the enabled HARQ process, and DCI information included in the DCI in the second DCI format is all for the enabled HARQ process and is not for the non-enabled HARQ process, for example: the bit number of the HARQ process number indication information included in the DCI of the first DCI format is determined according to the first HARQ process number, and the bit number of the HARQ process number indication information included in the DCI of the second DCI format is determined according to the second HARQ process number, so that the length of the DCI of the first DCI format and the length of the DCI of the second DCI format can be reduced, and the overhead of the DCI of the first DCI format and the overhead of the DCI of the second DCI format are reduced. Further, in the present application, the transmission frequency of the TB corresponding to the first HARQ process may be dynamically indicated through the DCI, so that the flexibility of the network device may be improved.

In this application, HARQ-ACK feedback information corresponding to a certain downlink physical channel is a decoding result of the downlink physical channel, and the decoding result may be Acknowledgement (ACK) information or Negative Acknowledgement (NACK) information.

Optionally, when the DAI information field is not used for the terminal device to generate the HARQ-ACK codebook, the DAI information field is set to a preset value. Alternatively, the DAI information field is used to indicate the first information.

Optionally, the preset value may be set by the network device according to an actual situation, for example, set to 1 or 4, and after the terminal device obtains the preset value, it may be known that the DAI information field is not used for the terminal device to generate the HARQ-ACK codebook. And/or the preset value is used for the terminal equipment to determine that the first downlink physical channel transmitted in the first HARQ process does not feed back HARQ-ACK information according to the first DCI format.

The TPC command information field is not used to adjust the transmit power of the uplink feedback channel of the terminal device.

Optionally, the uplink feedback channel is a PUCCH, or another uplink physical channel such as a PUSCH, which is not limited in this application.

Optionally, when a TPC command information field (TPC command for scheduled PUCCH) is not used to adjust the transmit power of the uplink feedback channel of the terminal device, the TPC command information field is used to indicate the first information. The first information may refer to the above explanation about the first information, which is not described herein again.

Or the number of information bits included in the DCI of the DCI format for scheduling the HARQ process corresponding to the non-enabled state is the same as the number of information bits included in the DCI of the DCI format for scheduling the HARQ process corresponding to the enabled state.

Optionally, the DCI format for scheduling the HARQ process corresponding to the non-enabled state and the DCI format for scheduling the HARQ process corresponding to the enabled state are the same DCI format refers to: the DCI format for scheduling the HARQ process corresponding to the non-enabled state and the DCI format for scheduling the HARQ process corresponding to the enabled state include identical information fields, for example: the DCI of this format includes an HARQ process number information field that is a non-enabled state and an enabled state HARQ process number information field, or the HARQ process indicated by the HARQ process number information field included in the DCI of this format may correspond to the non-enabled state or the enabled state.

Optionally, when the DCI includes an HARQ process number information field that is a non-enabled state and an enabled state, the size or length of the HARQ process number information field is determined according to the first HARQ process number and the second HARQ process number.

In this embodiment, for whether the DCI includes the CRC, the number of information bits included in the DCI, and the definitions of the first HARQ process number and the second HARQ process number, reference may be made to the above description, which is not repeated herein.

Fig. 5 is a schematic flow chart of a wireless communication method 500 provided in an embodiment of the present application, and as shown in fig. 5, the method 500 may include at least some of the following:

step S510: the terminal equipment receives a first downlink physical channel which is scheduled by the network equipment by using a first DCI format and is transmitted through a first HARQ process.

Step S520: and the terminal equipment determines to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel or determines not to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel according to the first indication information and/or the first DCI format.

Wherein the first HARQ process corresponds to a non-enabled state.

It should be understood that "the first downlink physical channel scheduled by the first HARQ process using the first DCI format" may also be expressed as "the first downlink physical channel scheduled by the first HARQ process using the DCI of the first DCI format".

For the description of the HARQ process status and the first downlink physical channel, reference may be made to the description of the HARQ process status and the first downlink physical channel, and details are not repeated here.

Optionally, the network device may send first indication information to the terminal device, where the first indication information is used to indicate the terminal device to perform HARQ-ACK feedback for downlink transmission in the non-enabled HARQ process. Or the first indication information is used for indicating that the terminal equipment does not perform HARQ-ACK feedback on downlink transmission in the non-enabled HARQ process.

Optionally, the first indication information is sent by the network device to the terminal device through at least one of physical layer signaling, such as DCI, higher layer parameter, such as RRC, or MAC CE. Of course, the first indication information may also be sent to the terminal device through other signaling, which is not limited in this application.

Optionally, in a case that the first indication information is used to indicate the terminal device to perform HARQ-ACK feedback for downlink transmission in the non-enabled HARQ process, the terminal device uses the same DCI format or the same DCI length to detect a PDCCH that schedules the downlink transmission using the non-enabled HARQ process and the enabled HARQ process.

Optionally, in a case that the first indication information is used to indicate that the terminal device does not perform HARQ-ACK feedback for downlink transmission in the non-enabled HARQ process, the terminal device uses different DCI formats or different DCI lengths to detect a PDCCH that schedules downlink transmission using the non-enabled HARQ process and the enabled HARQ process. For example, the terminal device uses a first DCI format to detect a PDCCH that schedules downlink transmission using a non-enabled HARQ process, and uses a second DCI format to detect a PDCCH that schedules downlink transmission using an enabled HARQ process, where the first DCI format and the second DCI format are different.

Alternatively, if the terminal device is configured by the network device through the high-layer signaling to use the first DCI format to detect the PDCCH for downlink transmission using the HARQ process in the non-enabled state, the terminal device is configured by the network device through the high-layer signaling to use the second DCI format to detect the PDCCH for downlink transmission using the HARQ process in the enabled state. Optionally, if the first DCI format and the second DCI format are the same DCI format, or the information bit number included in the DCI of the first DCI format is the same as the information bit number included in the DCI of the second DCI format, the terminal device performs HARQ-ACK feedback on downlink transmission in the non-enabled HARQ process. Optionally, if the first DCI format and the second DCI format are different DCI formats, or the information bit number included in the DCI of the first DCI format is different from the information bit number included in the DCI of the second DCI format, the terminal device does not perform HARQ-ACK feedback for downlink transmission in the non-enabled HARQ process.

Optionally, when the first indication information is used to indicate the terminal device to perform HARQ-ACK feedback for downlink transmission in a non-enabled HARQ process, in this case, the first DCI format is further used to schedule the HARQ process corresponding to the enabled state. That is, the DCI format for scheduling the HARQ process corresponding to the enabled state is the same as the DCI format for scheduling the HARQ process corresponding to the disabled state, or the information bit number included in the DCI format for scheduling the HARQ process corresponding to the disabled state is the same as the information bit number included in the DCI format for scheduling the HARQ process corresponding to the enabled state. Based on this, the terminal device receives the first downlink physical channel on the first HARQ process scheduled by the first DCI format, and even if the first HARQ process corresponds to the disabled state, since the first indication information is used to indicate the terminal device to perform HARQ-ACK feedback on downlink transmission in the HARQ process in the disabled state, the terminal device needs to perform HARQ-ACK feedback on downlink transmission in the HARQ process in the disabled state. Optionally, in this case, the terminal device determines to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel according to the first indication information and/or the first DCI format, or determines not to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel, which may actually be understood as: and the terminal equipment determines to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel according to the first indication information, or determines not to feed back the first HARQ-ACK feedback information corresponding to the first downlink physical channel.

Optionally, when the first DCI format is further used to schedule a HARQ process corresponding to an enabled state, the method further includes: and the terminal equipment carries out scheduling detection of the HARQ process corresponding to the enabled state according to the first DCI format. Or, the terminal device uses the first DCI format to detect the PDCCH that schedules the downlink transmission using the enabled HARQ process.

Optionally, when the first indication information is used to indicate that the terminal device does not perform HARQ-ACK feedback for downlink transmission in a non-enabled HARQ process, in this case, the first DCI format is not used to schedule the HARQ process corresponding to the enabled state. That is, the DCI format for scheduling the HARQ process corresponding to the enabled state is different from the DCI format for scheduling the HARQ process corresponding to the disabled state, or the information bit number included in the DCI format for scheduling the HARQ process corresponding to the disabled state is different from the information bit number included in the DCI format for scheduling the HARQ process corresponding to the enabled state.
