Description

Wireless communication method, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications, and in particular, to a wireless communication method, a terminal device, and a network device.

Background

In a Non-Terrestrial network (NTN) system, since a communication distance between a terminal device and a satellite or a network device is long, and a Round Trip Time (RTT) of signal transmission is much longer than the RTT of the Terrestrial communication system, a Hybrid Automatic Repeat Request (HARQ) mechanism in an existing New Radio (NR) system is no longer applicable to the NTN system. At present, HARQ enhancement can be performed in an NTN system in two ways, one is to increase the number of HARQ processes, and the other is to set the HARQ processes to enable. With respect to setting HARQ processes to be disabled, the network device may configure the disabling for some HARQ processes of the terminal device, and for the HARQ processes configured to be disabled, the terminal device does not need to perform HARQ feedback for data blocks transmitted in the HARQ processes. That is to say, for the HARQ process that is disabled by HARQ feedback, HARQ-ACK information does not need to be fed back and can be reused, so the network device can use the disabled HARQ process to schedule multiple data packets for the terminal device, thereby reducing the impact caused by the large RTT. For the HARQ process configured in the enabled state, the terminal device needs to perform HARQ feedback for the data block transmitted in the HARQ process, and the HARQ process can be reused.

In practical applications, both the disabled HARQ process and the enabled HARQ process may occur in a data transmission process, for example, downlink data transmission of a terminal device includes a Physical Downlink Shared Channel (PDSCH) that does not require HARQ-ACK feedback and also includes a PDSCH that requires HARQ-ACK feedback, and how to notify the HARQ feedback function state and a mechanism for scheduling data transmission at this time is a problem that needs to be optimized.

In an embodiment of the present application, optionally, the first state includes that the HARQ feedback function state is an enabled state. Optionally, the second state includes that the HARQ feedback function state is a non-enabled state.

In this application, the HARQ feedback function state corresponding to the downlink HARQ process or the uplink HARQ process of the terminal device may be a non-enabled state, and the non-enabled state is also referred to as a disabled state (disabled). For example, the network device may configure HARQ feedback function states corresponding to part or all HARQ processes of the terminal device to be an enabled state or a disabled state.

Optionally, the terminal device is indicated that the HARQ feedback function state corresponding to at least part of the downlink HARQ processes or at least part of the uplink HARQ processes is a non-enabled state.

Optionally, for a downlink HARQ process, if a HARQ feedback function state corresponding to one HARQ process is an enabled state, after receiving a Transport Block (TB) through the HARQ process, the terminal device needs to send HARQ-ACK information corresponding to the TB to the network device; or the terminal equipment needs to receive the feedback of the network equipment to the TB to reuse the HARQ process; or, the terminal device does not expect the network device to schedule downlink transmission by using the HARQ process again before the uplink feedback resource, e.g., PUCCH resource, corresponding to the TB is finished; or, the terminal equipment needs to perform corresponding HARQ-ACK information feedback according to the DCI scheduling the TB; or, the terminal equipment sends the HARQ-ACK information corresponding to the first physical channel transmitted in the HARQ process to the network equipment according to the DCI which is scheduled to transmit the first physical channel through the HARQ process.

Optionally, in this application, the HARQ-ACK information includes ACK information or NACK information corresponding to a decoding result of the TB.

Optionally, for an uplink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is an enabled state, after the terminal device sends a transport block TB through the HARQ process, the terminal device needs to receive feedback of the TB from the network device to reuse the HARQ process (for example, use the HARQ process to send a new TB or send the TB again); or the terminal device waits for the feedback of the first physical channel transmitted in the HARQ process from the network device.

Optionally, for an uplink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is a non-enabled state, it indicates that after the terminal device sends a TB through the HARQ process, the terminal device may reuse the HARQ process without receiving feedback of the network device for the TB (e.g., send a new TB or send the TB again through the HARQ process); or the terminal device does not wait for the feedback of the first physical channel transmitted in the HARQ process from the network device.

Optionally, the first length of time is less than the second length of time.

According to the embodiment of the application, the first control information format may correspond to a first state or a second state, for example, the HARQ feedback function state is an enabled state or a non-enabled state, and the state corresponding to the first control information format is related to whether the received first physical channel includes the second control information format, and accordingly, the terminal device may determine whether the second control information format exists according to the state of the first control information format, and further determine whether the second control information format is received, so as to obtain resource indication information in the second control information format for data transmission.

Correspondingly, an embodiment of the present application further provides a wireless communication method, with reference to fig. 3, where the method is applied to a network device, and includes:

s201, sending a first control information format and a first physical channel to a terminal device, wherein the first control information format is used for scheduling or activating transmission of the first physical channel, and the first control information format corresponds to a first state or a second state; wherein,

the first control information format corresponds to a first state, the first physical channel comprises a second control information format; or,

the first control information format corresponds to a second state, and the first physical channel does not include the second control information format.

By adopting the communication method of the embodiment of the application, the network equipment sends the first physical channel and the first control information format to the terminal equipment, and indicates whether the first physical channel contains the second control information format or not through two states corresponding to the first control information, so that the terminal equipment can determine whether to receive the second control information format or not so as to obtain the resource indication information in the second control information format for data transmission.

In an embodiment of the present application, optionally, the first control information format corresponding to the first state or the second state includes: the first physical channel scheduled by the first control information format corresponds to a first state or a second state; or, the first physical channel activated by the first control information format corresponds to a first state or a second state.

For example, the first physical channel includes a dynamically scheduled physical channel, and the HARQ feedback function state of the HARQ process corresponding to the first physical channel scheduled by the first control information format is an enabled state or a disabled state.

For another example, the first physical channel includes a semi-persistent scheduling or pre-configured physical channel, and the HARQ feedback function state of the HARQ process corresponding to the first physical channel activated by the first control information format is an enabled state or a disabled state.

In an embodiment of the present application, optionally, the first control information format corresponds to a first state, and the first physical channel includes a second control information format, including:

if the first control information format corresponds to a first state, the first physical channel comprises a second control information format; or,

and if the first physical channel comprises a second control information format, the first control information format corresponds to a first state.

For example, when the HARQ feedback function state of the HARQ process corresponding to the first physical channel scheduled by the first control information format is an enabled state, the first physical channel includes a second control information format.

For another example, when the first physical channel includes the second control information format, the HARQ feedback function state of the HARQ process corresponding to the first physical channel scheduled by the first control information format is an enabled state.

In an embodiment of the present application, optionally, the first control information format corresponds to a second state, and the first physical channel does not include the second control information format, including:

if the first control information format corresponds to a second state, the first physical channel does not comprise a second control information format; or, if the first physical channel does not include the second control information format, the first control information format corresponds to the second state.

For example, when the HARQ feedback function state of the HARQ process corresponding to the first physical channel scheduled by the first control information format is a non-enabled state, the first physical channel does not include the second control information format.

For another example, when the first physical channel does not include the second control information format, the HARQ feedback function state of the HARQ process corresponding to the first physical channel scheduled by the first control information format is a non-enabled state.

In an embodiment of the present application, optionally, the first control information format corresponds to a first state or a second state, and includes:

first indication information included in the first control information format indicates a first state or a second state; or,

the first indication information included in the first control information format indicates whether the second control information format is included in the first physical channel.

It should be understood that "indication" mentioned in the embodiments of the present application may be a direct indication, an indirect indication, or an indication of an association relationship. For example, a indicates B, which may indicate that a directly indicates B, e.g., B may be obtained by a; it may also mean that a indicates B indirectly, for example, a indicates C, and B may be obtained by C; it can also mean that there is an association between a and B.

In one embodiment of the present application, the first indication information includes independent indication information. For example, the first indication information includes 1 bit, a first state of the first indication information, for example, "1", may indicate that the first state, for example, the HARQ feedback function, is an enabled state or the second control information format is included in the first physical channel, and a second state of the first indication information, for example, "0", may indicate that the second state, for example, the HARQ feedback function, is a disabled state or the second control information format is not included in the first physical channel.

In another embodiment of the present application, the first indication information includes HARQ process indication information, and the terminal device may obtain the first state or the second state corresponding to the first control information format according to the HARQ process indication information.

For example, the network device configures the HARQ feedback function states corresponding to HARQ processes 0 to 7 as an enabled state and configures the HARQ feedback function states corresponding to HARQ processes 8 to 15 as a disabled state through a higher layer signaling, for example, an RRC parameter. If the terminal device receives the HARQ process indication information in the first DCI indicating HARQ5, the terminal device may determine that the HARQ feedback function state corresponding to the first physical channel scheduled by the first control information or the first control information is an enabled state, or the terminal device may determine that the first physical channel includes the second control information format. If the terminal device receives the HARQ process indication information indicating HARQ9 in the first control information, the terminal device may determine that the HARQ feedback function state corresponding to the first physical channel scheduled by the first control information or the first control information is a non-enabled state, or the terminal device may determine that the first physical channel does not include the second control information format.

the second indication information corresponding to the first control information format indicates a first state or a second state; or, the second indication information corresponding to the first control information format indicates whether the first physical channel includes the second control information format.

Optionally, the second indication information corresponding to the first control information format includes at least one of a radio network device temporary identifier RNTI corresponding to the first control information format, a search space set corresponding to the first control information format, and an aggregation level corresponding to the first control information format.

In an embodiment of the present application, optionally, the first control information format includes third indication information, where the third indication information is used to obtain a size of a resource occupied by the second control information format in the first physical channel.

For example, the third indication information indicates a first rate compensation factor β of the second control information format, where β is used to determine a ratio of a total bit number of the second control information format to a total bit number of data in the first physical channel, so as to determine a number of Resource Elements (REs) occupied by the second control information format in resources corresponding to the first physical channel; and/or the third indication information indicates a second code rate compensation factor α of the second control information format, where α is used to determine an upper limit of the number of REs occupied by the second control information format.

In this embodiment of the present application, optionally, the first control information format includes fourth indication information, where the fourth indication information is used to indicate the number of times of repeated transmission corresponding to the first physical channel.

Fig. 6 schematically shows a usage process of a HARQ process with HARQ feedback de-enabled in a downlink carrier, and for the HARQ process 7 with HARQ feedback de-enabled, when the terminal device receives scheduling of the HARQ process 7 from the network device and NDI information corresponding to the HARQ process 7 is turned over, it indicates that the HARQ process 7 is used for transmitting a new data packet. For the decoding result of the PDSCH transmitted in the scheduled HARQ process 7, the terminal device does not need to feed back to the network device.

According to the above embodiment provided by the application, the terminal device may determine, according to the first control information format, the HARQ process that does not need to perform HARQ-ACK information feedback, and may also determine the HARQ process that needs to perform HARQ-ACK information feedback.

The following describes an implementation process of the embodiment of the present application by taking downlink transmission and uplink transmission as examples respectively.

For downlink transmission, in one possible implementation, the terminal device receives a first DCI format, where the first DCI format indicates that a first PDSCH is transmitted according to a first HARQ process; the terminal equipment determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state or a non-enabled state according to the first DCI format, and the first DCI does not include uplink resource indication information for HARQ-ACK feedback; if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state, the terminal device receives a second DCI format, where the second DCI format includes uplink resource indication information used for HARQ-ACK feedback, for example, indication information of a PUCCH resource or a TPC command of a PUCCH, and the terminal device sends ACK information or NACK information corresponding to the first PDSCH according to the first DCI format and the second DCI format, or if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is a non-enabled state, the terminal device does not receive the second DCI format, or the terminal device does not send ACK information or NACK information corresponding to the first PDSCH according to the first DCI format.

In another possible implementation, the terminal device receives a first DCI format, where the first DCI format indicates that a first PDSCH is transmitted according to a first HARQ process; the terminal equipment determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state or a non-enabled state according to the first DCI format, and the first DCI does not include uplink resource indication information for HARQ-ACK feedback; if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state, the terminal device obtains uplink resource indication information for HARQ-ACK feedback according to a high-level parameter of the network device, for example, indication information of a PUCCH resource or a TPC command of a PUCCH, and the terminal device sends ACK information or NACK information corresponding to the first PDSCH according to the first DCI format and the high-level parameter, or if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is a disabled state, the terminal device does not send ACK information or NACK information corresponding to the first PDSCH according to the first DCI format.

Fig. 7 and 8 illustrate diagrams of scheduling a first PDSCH using a first DCI format (fig. 7) and using the first and second DCI formats (fig. 8), respectively, in downlink scheduling. Because the first DCI format does not include the uplink resource indication information for HARQ-ACK feedback any more, the number of information bits in the first DCI format can be reduced, and the detection reliability of the first DCI can be enhanced; and for the HARQ process needing HARQ-ACK information feedback, a second DCI format is adopted for indication, and data transmission is ensured to be error-free.

In comparison, for the current DCI format 1_0, DCI format 1_1 and DCI format 1_2, each DCI format includes a plurality of information fields for the terminal device to perform uplink HARQ feedback, or for the terminal device to feed back HARQ-ACK information corresponding to PDSCH transmission. If a certain HARQ process is an uplink HARQ feedback disabled HARQ process, all information fields for performing uplink HARQ feedback by the terminal device do not need to be indicated by DCI for the HARQ process, so that the length of DCI information bits is reduced if the first DCI format of the embodiment of the present application does not include the information fields; for the HARQ process that needs to feed back HARQ-ACK information, the second DCI format in the embodiment of the present application includes these corresponding information fields, and may be transmitted together with a physical channel. Optionally, the second DCI format is carried by the first PDSCH.

Optionally, the terminal device determines, according to the first DCI format, a HARQ feedback function state corresponding to the first HARQ process, where the HARQ feedback function state includes at least one of the following conditions:

the HARQ feedback function state corresponding to the first HARQ process may be determined according to first indication information included in the first DCI format, where the first indication information may be a display indication or an implicit indication.

The HARQ feedback function state corresponding to the first HARQ process may be determined according to second indication information corresponding to the first DCI format, for example, RNTI, search space set, or aggregation level information. For example, the terminal device is configured with a first RNTI and a second RNTI, where the first RNTI is used for scrambling downlink grant DCI corresponding to the uplink HARQ feedback de-enabled HARQ process, and the second RNTI is used for scrambling downlink grant DCI corresponding to the uplink HARQ feedback enabled HARQ process.

The first condition is as follows: and if the terminal equipment determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state, the terminal equipment receives a second DCI format, wherein the second DCI format comprises uplink resource indication information for HARQ-ACK feedback.

Optionally, the second DCI format is carried in the first PDSCH.

Optionally, the second DCI format is an independent encoding.

Optionally, the mapping position of the second DCI format in the first PDSCH is before the data bits, e.g., not later in time domain than the data bits or concatenated before the data bits.

And a second condition: and if the terminal equipment determines that the HARQ feedback function state corresponding to the first HARQ process is a non-enabled state, the terminal equipment does not receive the second DCI format. Optionally, DCI information is not included in the first PDSCH.

Optionally, at least one of the following information fields is not included in the first DCI format: downlink Assignment Indication (DAI), TPC command of PUCCH, PUCCH resource indication, and timing indication of PDSCH to HARQ feedback.

Optionally, the first DCI format includes third indication information, where the third indication information is used to indicate resources occupied by the second DCI.

Optionally, the first DCI format includes fourth indication information, where the fourth indication information is used to indicate a number of repetitions corresponding to the first PDSCH.

Optionally, the second DCI format includes the following information fields: TPC commands for PUCCH.

Optionally, the second DCI format includes at least one of the following information fields: DAI, PUCCH resource indication, timing indication from PDSCH to HARQ feedback, one-shot HARQ-ACK feedback request, PDSCH grouping indication, new feedback indication and trigger feedback group indication.

Optionally, the second DCI format includes at least one of the following information fields: the new data indicates NDI, redundancy version information, HARQ process number.

In order to more clearly understand the first DCI format and the second DCI format of the embodiment of the present application, the DCI domains in the current DCI format 1_0, DCI format 1_1, and DCI format 1_2 are respectively used as comparison targets, and table 4 to table 6 show various implementation forms or various situations of the first DCI format of the embodiment of the present application.

Wherein 0 bit indicates that the information field is not included in the first DCI format.

Example two: DCI field included in first DCI format

Example three: DCI field included in first DCI format

In the following, the DCI domains in the current DCI format 1_0, DCI format 1_1 and DCI format 1_2 are respectively used as comparison targets, and table 7 to table 9 show various implementation forms or various situations of the second DCI format in the embodiment of the present application.

Wherein 0 bit indicates that the information field is not included in the second DCI format.

Example one: DCI fields included in a second DCI format

TABLE 7

Example two: DCI field included in second DCI format

TABLE 8

Example three: DCI field included in second DCI format

TABLE 9

By using the embodiment of the application, after receiving a first DCI format of data scheduling, the terminal device can determine whether the corresponding HARQ process needs to perform HARQ-ACK information feedback according to the first DCI format, and the first DCI format does not include indication information of uplink resources for HARQ-ACK feedback, which is equivalent to uniformly designing the scheduling of PDSCH that needs to perform HARQ-ACK information feedback and the scheduling of the DCI of PDSCH that does not need to perform HARQ-ACK information feedback, so that the number of information domain bits of the DCI is reduced, and the situation that the number of DCI information bits is different does not occur, thereby achieving the effect that the number of additional blind detection times is not required to be increased and the reliability of DCI detection can be improved.

The specific implementation manner of the embodiment of the present application is described above by taking downlink transmission as an example, where the first control information format includes a first DCI format, the second control information format includes a second DCI format, and the first physical channel includes the first PDSCH.

For uplink transmission, the terminal equipment receives a first DCI format, and the first DCI format indicates that a first PUSCH is transmitted according to a first HARQ process; and the terminal equipment determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state or a non-enabled state according to the first DCI format.

In a possible implementation manner, if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state, the first PUSCH transmitted by the terminal device includes the first UCI, or if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is a disabled state, the first PUSCH transmitted by the terminal device does not include the first UCI.

In another possible implementation manner, if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is an enabled state, the first PUSCH transmitted by the terminal device does not include the first UCI, or if the terminal device determines that the HARQ feedback function state corresponding to the first HARQ process is a disabled state, the first PUSCH transmitted by the terminal device includes the first UCI. In this case, when the first HARQ process corresponds to the disabled state, the first UCI may further include fifth indication information, where the fifth indication information is used to indicate the number of repeated transmissions corresponding to the first PUSCH.
