Background

The research of a New Radio (NR) system mainly considers two Frequency bands, namely, frequency band (FR) 1 and FR2, and along with the evolution of the NR system, a New Frequency band, i.e., a technology on a high Frequency, is also researched, and for convenience of description, the New Frequency band is called a high Frequency band.

The high frequency band includes a licensed spectrum and an unlicensed spectrum, wherein the licensed spectrum may also be referred to as an unshared spectrum, and the unlicensed spectrum may also be referred to as a shared spectrum.

For unlicensed spectrum in the high-frequency band, there is no clear solution for supporting a channel access mode assisted by the receiving side.

Optionally, in the embodiment of the present invention, the "protocol" may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited by the present invention.

Before explaining the wireless communication method provided by the embodiment of the invention in detail, the high frequency band is explained.

Studies of NR systems currently mainly consider two frequency bands, FR1 and FR2, where FR1 and FR2 include the frequency ranges shown in table 1.

Table 1, FR1 and FR2 definitions

Frequency band definition	Corresponding frequency range
FR1	410MHz–7.125GHz
FR2	24.25GHz–52.6GHz

As NR systems evolve, new frequency bands, i.e. technologies at high frequencies, are also beginning to be studied. For convenience of description, the high frequency band is denoted by FRX in the present invention, and the range of the frequency domain included in the high frequency band is shown in table 2. It should be understood that the high band name should not be construed as limiting in any way. For example, FRX may be FR3.

TABLE 2 FRX definition

Frequency band definition	Corresponding frequency range
FRX	52.6GHz–71GHz

The FRX band includes licensed spectrum and also unlicensed spectrum. Alternatively, the FRX band includes a non-shared spectrum or a dedicated spectrum, and also includes a shared spectrum.

Unlicensed spectrum is a nationally and regionally divided spectrum that can be used for radio communications and is generally considered to be a shared spectrum, i.e., communication devices in different communication systems can use the spectrum as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum grant to be applied to the government.

In order for individual communication systems using unlicensed spectrum for wireless communication to co-exist friendly over that spectrum, some countries or regions specify regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of "listen before talk (Listen Before Talk, LBT)", that is, the communication device needs to perform channel detection before performing signal transmission on a channel of an unlicensed spectrum, and the communication device can perform signal transmission only when the channel detection result is that the channel is idle; if the communication device is busy as a result of channel detection on a channel of the unlicensed spectrum, the communication device is unable to signal. For another example, in order to ensure fairness, the communication device cannot use the unlicensed spectrum channel for signal transmission for more than a certain length of time in one transmission. As another example, to avoid that the power of a signal transmitted on a channel of unlicensed spectrum is too high, affecting the transmission of other important signals on that channel, a communication device needs to follow a limit of not exceeding the maximum power spectral density when using the channel of unlicensed spectrum for signal transmission. It should be noted that in some countries or regions, there is no requirement for LBT for unlicensed spectrum included in the FRX band.

The subcarrier spacing considered for the FRX band may be greater than the subcarrier spacing for FR2, with the current candidate subcarrier spacing comprising at least one of the following: 240kHz, 480kHz, 960kHz, 1.902MHz, 3.84MHz. As an example, the corresponding parameter sets (Numerology) at these candidate subcarrier spacings are shown in table 3 below.

Table 3, examples of parameter sets corresponding to candidate subcarrier spacing for FRX frequency band

Subcarrier spacing	Symbol length	NCP Length	ECP Length	Symbol tape NCP Length	Time slot length
240kHz	4.16μs	0.2902μs	1.04μs	4.452μs	62.5μs
480kHz	2.08μs	0.146μs	0.52μs	2.226μs	31.25μs
960kHz	1.04μs	0.073μs	0.26μs	1.113μs	15.625μs

Next, a partial concept of the shared spectrum will be described.

Maximum channel occupancy time (Maximum Channel Occupation Time, MCOT): refers to the maximum length of time that channel detection (channel sensing) on a channel sharing the spectrum will allow for signal transmission using that channel.

Channel occupancy time (Channel Occupancy Time, COT): the time length of signal transmission using the channel after the channel detection on the channel of the shared spectrum is successful may also be considered as the time length of occupying the channel after the channel detection on the channel of the shared spectrum is successful. Wherein the signal occupying channel may be continuous or discontinuous for the length of time, which includes the total time for signal transmission by the device initiating channel occupancy and the device sharing channel occupancy.

Channel occupancy time (gNB/eNB-initiated COT) of the network device: also referred to as network device initiated COT, refers to the primary channel occupation time obtained by a network device after successful channel detection on a channel sharing a spectrum. The COT initiated by the network device can be used for transmission by the network device and can also be used for transmission by the terminal device under the condition that a certain condition is met.

Channel occupation time (UE-initiated COT) of terminal device: the COT initiated by the terminal equipment refers to the primary channel occupation time obtained by the terminal equipment after successful channel detection on the channels sharing the frequency spectrum. The COT initiated by the terminal device can be used for transmission by the terminal device and can also be used for transmission by the network device under the condition that a certain condition is met.

Downlink transmission opportunity (DL transmission burst): a set of downlink transmissions by a network device (i.e., including one or more downlink transmissions) that are consecutive transmissions (i.e., there is no gap between the downlink transmissions), or that have a gap in the set of downlink transmissions that is less than or equal to a predetermined value, e.g., 16 microseconds (μs) in the FR1 band. If the gap between two downlink transmissions by the network device is greater than the preset value of 16 mus, then the two downlink transmissions are considered to belong to two downlink transmission opportunities.

Uplink transmission opportunity (UL transmission burst): a group of uplink transmissions by a terminal device (i.e. comprising one or more uplink transmissions), the group of uplink transmissions being either continuous transmissions (i.e. no gaps between the plurality of uplink transmissions), or the group of uplink transmissions having gaps but less than or equal to a predetermined value, e.g. 16 mus in the FR1 band. If the gap between two uplink transmissions by the terminal device is greater than the preset value of 16 mus, then the two uplink transmissions are considered to belong to two uplink transmission opportunities.

It should be appreciated that in the FRX band, the above-mentioned preset value may be other values, for example, 8 μs. The invention is not limited in this regard.

Channel detection succeeds: also known as LBT success or channel detection idle. For example, the energy detection in a listening slot for a channel is below an energy detection threshold.

Channel detection failure: also known as LBT failure or busy channel detection. For example, the energy detection in a listening slot for a channel is greater than or equal to an energy detection threshold.

The receiver side secondary channel listening is an LBT approach similar To the Request To Send/Clear To Send (RTS/CTS) mechanism of Wi-Fi systems. As shown in fig. 2, the network device sends an RTS message to ask the terminal device if it is ready to receive data before transmitting. After receiving the RTS message, if the LBT procedure is successful, the terminal device may send a CTS-like message to the network device, for example, report its own interference measurement result, inform the network device that it is ready to receive data, and after receiving the CTS message, the network device may perform downlink transmission to the terminal device. Or if the terminal device does not receive the RTS message, or the terminal device receives the RTS message but cannot send the CTS message due to failure of the LBT procedure, the terminal device will not send the CTS message to the network device, and the network device may discard downlink transmission to the terminal device if the network device does not receive the CTS message of the terminal device.

In the FRX band, for countries and regions where LBT is required, LBT modes (i.e., channel access modes) may include omni-directional LBT, receiver-side assisted LBT, and non-LBT modes. For channel access modes without LBT, certain conditions such as automatic transmit power control (Automatic Transfer Power Control, ATPC), dynamic frequency selection (Dynamic frequency selection, DFS), long term interference detection or other interference cancellation mechanisms may also need to be restricted. In addition, the switching can be performed between the channel access which does not do LBT and the channel access which does not do LBT.

For countries and regions where no LBT requirements are present, it is also considered whether certain conditions are to be introduced, such as whether DFS needs to be applied, ATPC needs to be applied, long-term interference detection needs to be applied, a certain duty cycle is limited, a certain transmit power is limited, MCOT is limited, etc.

Since the frequency band of FRX is relatively high, the LBT scheme on the unlicensed spectrum in the FRX frequency band is different from the LBT scheme on the unlicensed spectrum in the FR1 frequency band. For example, a channel access method based on the transmission/reception interaction, also referred to as a receiving side auxiliary channel access method, may be introduced into the FRX. If the manner of supporting the receiving side auxiliary LBT in the NR-U system on the FRX band is to be used, when the terminal device receives the request transmission information, it has not yet been explicitly proposed how to transmit the corresponding response information. Therefore, the following technical solutions of the embodiments of the present invention are provided, and the technical solutions of the embodiments of the present invention may be applied, but are not limited to, to unlicensed spectrum on FRX.

In order to facilitate understanding of the technical solution of the embodiments of the present invention, the technical solution of the present invention is described in detail below through specific embodiments.

Alternatively, if the first device needs to feed back acknowledgement information corresponding to the plurality of frequency domain resources through one physical channel or physical signal, the acknowledgement information corresponding to the plurality of frequency domain resources may be transmitted through the PUCCH. If the first device needs to feed back the response information corresponding to one frequency domain resource through one physical channel or physical signal, the response information corresponding to one frequency domain resource can be transmitted through the PUCCH or the PRACH or the SRS.

Alternatively, if the response information of the plurality of frequency domain resources corresponds to one physical channel or physical signal, the one physical channel or physical signal may be PUCCH, and the second device may receive the response information of the corresponding plurality of frequency domain resources through the PUCCH. If the response information of one frequency domain resource corresponds to one physical channel or physical signal, the one physical channel or physical signal may be PUCCH or PRACH or SRS, and the second device may receive the response information of the corresponding one frequency domain resource through the PUCCH or PRACH or SRS.

By allowing the reply information to be transmitted over different types of resources, flexibility is provided for the resource configuration of the network device. For example, the network device can synthesize the service load condition of the terminal devices in the cell, and flexibly configure the resource types corresponding to the response information for different terminal devices, so that the response resources of different terminal devices can be multiplexed, and the utilization efficiency of spectrum resources is improved.

Taking the example that the information determined by the acknowledgement resource indication information includes information three, the DAI information may include DAI count (C-DAI) information and/or DAI total number (Total Downlink Assignment Index, T-DAI) information. For example, the first device may determine DAI information according to the acknowledgement resource indication information and determine a location of the acknowledgement information in the feedback codebook according to the DAI information.

Taking the case that the information determined by the response resource indication information comprises information IV as an example, the first device determines the power control information according to the response resource indication information, determines the transmitting power for transmitting the response information according to the power control information, and sends the response information according to the determined transmitting power.

Optionally, the power control information is TPC command information for PUCCH (TPC command for scheduled PUCCH).

In some embodiments, the determining of the response resource indication information includes at least one of:

determining a mode C1 according to high-level parameters;

determining a mode C2, indicated by the second device;

determining a mode C3 and predefining.

In the determining mode C1, at least one of the response resource indication information is determined according to a preconfigured higher-layer parameter. The higher layer parameters may be configured by the network device or by the terminal device. The terminal device configured with the higher layer parameters may be a terminal device having a control function. For example, the terminal device with the control function is a head-set terminal of the terminal group to which the terminal device belongs.

Optionally, if the determining manner of at least one of the response resource indication information is the determining manner C1, the first control information may not include the information or the information in the response resource indication information.

Taking the case that the time domain position information is determined according to the high-level parameter as an example, the first device is configured with an interval value by the high-level parameter, the interval between the time domain position of the response resource and the time domain position of the first control information is the interval value, or the interval between the response resource and the time domain position of the first control information is the first available response resource after the interval value.

When the interval between the time domain position of the response resource and the time domain position of the first control information is an interval value, the first device transmits the response information at the position where the interval between the time domain position of the response resource and the time domain position of the first control information is an interval value. Accordingly, the second device receives the reply message at the location. In an example, the first device is configured with a higher-level parameter configuration interval value of Ka, and when the first device receives the first control information on the time slot n, the first device sends the response information on the time slot n+ka.

When the response resource is the first available response resource after the interval value from the time domain position of the first control information, the first device transmits response information on the first available response resource after the position after the interval value from the time domain position of the first control information. In an example, the interval value configured by the higher-layer parameter in the first device is Ka, and the first device receives the first control information on the time slot n, and the location of the response resource is the first available response resource after the interval value condition is met, for example, the time slot n+ka.

In the determining mode C2, at least one of the response resource indication information is indicated by the second device. The second device may indicate at least one of the response resource indication information by the indication information.

Optionally, the indication information is carried in the first control information. For example, the first control information includes acknowledgement resource indication information, where the acknowledgement resource indication information is used to indicate at least one information associated with the acknowledgement resource. After the first device receives the first control information, at least one of the response resource indication information can be determined according to the first control information.

Taking the example that the time domain location information is indicated by the second device through the acknowledgement resource indication information in the first control information. The second device may configure a plurality of interval values through a higher layer parameter, and indicate which value of the plurality of interval values should be used through response resource indication information in the first control information, and the first device may determine a time domain position of the response resource according to the interval value indicated by the response resource indication information.

In the determining mode C3, at least one of the response resource indication information is predefined. The first device or the second device may be implemented by storing a corresponding code, a table, or other means for determining at least one of the response resource indication information in advance. The embodiment of the invention does not limit any predefined mode of at least one information in the response resource indication information, for example, the predefined mode can be defined in a protocol.

Optionally, if the determining manner of at least one of the response resource indication information is determining manner C3, the first control information may not include the information or the indication information of the information in the response resource indication information.

Also taking the time domain position information in the determining way C1 as an example, in the determining way C3 the time domain position information is predefined, or alternatively the aforesaid interval value may be predefined. Specifically, an interval value is predefined in the first device, and an interval between a time domain position of the acknowledgement resource and a time domain position of the first control information is the interval value, or an interval between the acknowledgement resource and a time domain position of the first control information is a first available acknowledgement resource after the interval value. Reference is made to the foregoing for specific embodiments, which are not repeated here.

Similarly, the above-described determination methods may be used in combination without contradiction.

In the embodiment of the invention, the resource information in the response resource indication information is determined according to the high-level parameters or indicated by the second equipment or predefined; and/or the time domain location information in the acknowledgement resource indication information is determined from higher layer parameters or indicated or predefined by the second device; and/or the downlink allocation indication information in the response resource indication information is determined according to the higher layer parameters or indicated by the second device or predefined; and/or the power control information in the acknowledgement resource indication information is determined according to higher layer parameters or indicated or predefined by the second device.

In an example, the resource information in the response resource indication information is determined by the determining means C1.

In an example, the time domain location information in the acknowledgement resource indication information is determined by the determining way C2.

In the embodiment of the invention, different information included in the response resource indication information can be determined by the same determination mode or different determination modes.

In an example, the resource information, the time domain location information, the downlink allocation indication information in the response resource indication information are determined by the determining method C1.

In an example, the resource information and the time domain location information in the acknowledgement resource indication information are determined by the determining method C2, and the downlink allocation indication information is determined by the determining method C3.

In an example, taking the determination of the resource information in the acknowledgement resource indication information by the determining manner C2 as an example, the first device is configured or predefines a plurality of acknowledgement resources by the higher layer parameter or the system information, the second device indicates which of the plurality of acknowledgement resources should be used by the acknowledgement resource indication information in the first control information, and the first device determines the acknowledgement resource for transmitting the acknowledgement information from the plurality of acknowledgement resources by the acknowledgement resource indication information in the first control information.

In an example, the second device configures or predefines one acknowledgement resource by higher layer parameters or system information. In this case, the acknowledgement resource indication information in the first control information does not include resource information for determining the acknowledgement resource.

In some embodiments, in a case where the first device determines to send the response information (for example, ACK information) to the second device, in a case where channel access corresponding to the response information is successful, the first device sends the response information to the second device; and under the condition that the channel access corresponding to the response information fails, the first equipment does not send the response information to the second equipment.

For the second device, if the second device receives the acknowledgement information (e.g., ACK information), it is determined that wireless communication, such as downlink transmission or sidelink transmission, can be performed to the first device.

In some embodiments, if the format corresponding to the first control information is a format for instructing the network device to initiate a request-response procedure to the terminal device, the first control information includes transmission request information.

In some embodiments, the format indication information comprises 1 bit. For example, when the format indication information indicates a preset value, such as "1", the format indication information is used to indicate that the format corresponding to the first control information is a format used to indicate the network device to initiate a request-response procedure to the terminal device; when the format indication information indicates another preset value, for example, "0", the format indication information is used to indicate that the format corresponding to the first control information is not a format for indicating the network device to initiate a request-response procedure to the terminal device.

If a certain bit in the M bits indicates a preset value, for example, a "1", the bit is used to indicate the request-response process initiated by the network device to the terminal device, and corresponds to the frequency domain resource corresponding to the bit; or if a certain bit of the M bits indicates another preset value, for example, "0", the bit is used to indicate that the network device does not initiate the request-response procedure to the terminal device, and the frequency domain resource corresponding to the bit corresponds to the request-response procedure.

The terminal equipment determines a target first reference signal index which is related when the response information is transmitted currently from the plurality of first reference signal indexes according to the first beam information, so as to determine a beam used for transmitting the response information, or determines to transmit the response information according to the target first reference signal index.

As another example, if the terminal device is preconfigured with a first reference signal index associated with transmission of acknowledgement information by a higher layer parameter, the terminal device determines a beam used for transmitting acknowledgement information according to the configured first reference signal index, or determines to transmit acknowledgement information according to the first reference signal index. In this case, the first control information may not be used to determine the first beam information.

In some embodiments, the first beam information has an association with beam information associated with the first control information or has an association with beam information associated with a physical channel; alternatively, the first beam information is determined according to the beam information associated with the first control information or determined according to the beam information associated with the physical channel. Wherein the physical channel comprises a physical channel corresponding to the request-response process.

Instance III, terminal equipment determines channel access mode corresponding to response information transmission

In some embodiments, the channel access manner corresponding to the transmission of the response information is determined according to channel access indication information, where the channel access indication information may be predefined rules or indicated by the network device or determined according to higher layer parameters.

In some embodiments, the channel access manner includes one of: channel access without channel detection, channel access of the first type, channel access of the second type.

In some embodiments, the first type of channel access is a channel access manner of a plurality of listening slots with random back-off, and the second type of channel access is a channel access manner of a fixed listening slot length.

As an example, the channel access indication information may be a predefined rule. For example, the predefined rules include: the transmission of the response information corresponds to channel access without channel detection. For another example, the predefined rule includes: and under the condition that the first condition is met, the response information transmission corresponds to the channel access without channel detection. For another example, the predefined rule includes: the transmission of the reply information corresponds to a second type of channel access. For another example, the predefined rule includes: and under the condition that the first condition is met, the response information transmission corresponds to the second type of channel access.

Wherein the first condition includes at least one of: the interval between the end position of the first control information transmission and the start position of the response information transmission is less than or equal to a first preset value; the transmission of the acknowledgement information meets a certain duty cycle limitation.

As an example, channel access indication information is indicated by the network device. For example, the first control information includes the transmission request information, and the transmission request information includes channel access indication information, where the channel access indication information is used to indicate a channel access mode corresponding to the response information and/or an extended cyclic prefix CPE length corresponding to the response information. The terminal equipment can determine the channel access mode corresponding to the response information and/or the CPE length corresponding to the response information according to the channel access indication information.

As an example, the channel access indication information is configured by the network device via higher layer parameters. For example, the network device configures, through a higher layer parameter, a channel access mode corresponding to the response information to be a channel access which does not perform channel detection, or a first type of channel access, or a second type of channel access. For another example, the network device configures the CPE length corresponding to the response information through a higher layer parameter.

In some embodiments, the channel detection beam type corresponding to the channel access mode includes a corresponding omni-directional channel detection or a corresponding directional channel detection. For example, the first type of channel access includes a first type of channel access corresponding to omni-directional channel detection or a first type of channel access corresponding to directional channel detection; the second type of channel access includes a second type of channel access corresponding to omni-directional channel detection or a second type of channel access corresponding to directional channel detection.

In some embodiments, the channel detection beam type corresponding to the channel access mode is determined based on a higher-level parameter configured by the network device or indicated by the channel access indication information or predefined.

In some embodiments, if the channel detection beam type corresponding to the channel access mode is corresponding to directional channel detection, the terminal device needs to determine beam information associated with the channel access mode.

And fourthly, the terminal equipment determines the beam information associated with the channel access mode of the response information transmission. The beam information associated with the channel access mode corresponding to the response information transmission is referred to as second beam information.

In some embodiments, the second beam information (i.e. the directional channel detection beam direction or the beam used in the channel access procedure) is determined based on or indicated by the network device configured higher layer parameters or predefined by the channel access indication information.

In some embodiments, the second beam information has an association with the first reference signal information associated with acknowledgement information, e.g., a first reference signal index.

In some embodiments, the second beam information has an association relationship with the beam information associated with the first control information. For example, the second beam information has an association relationship with the first TCI information or the second reference signal information, for example, a second reference signal index.

In some embodiments, the second beam information has an association with beam information associated with the physical channel. For example, the second beam information has an association relationship with the second TCI information or the third reference signal information, for example, a third reference signal index.

It should be understood that the definition and determination methods of the first reference signal information, the second reference signal information, the third reference signal information, the first TCI information, the second TCI information, and the physical channel are the same as those described above, and are not repeated here.

In some embodiments, the second beam information is indicated by the network device through the first control information. For example, the first control information includes the transmission request information, and the beam indication information in the transmission request information is used to determine the second beam information.

As an example, the terminal device is preconfigured with a plurality of information associated with the second beam by the higher layer parameter, and the first control information includes beam indication information, and the beam indication information includes the second beam information. And the terminal equipment determines target information related to the second wave beam when being currently used for transmitting response information from the plurality of pieces of information related to the second wave beam according to the second wave beam information, so as to determine the wave beam used in the channel access process of the response information, or determines the wave beam determined according to the target information to carry out directional channel detection.

As another example, if the terminal device is preconfigured with the information associated with the second beam by the higher-layer parameter, the terminal device determines a beam used in a channel access procedure of the response information according to the information associated with the second beam, or determines a beam determined according to the information associated with the second beam to perform directional channel detection. In this case, the first control information may not be used to determine the second beam information.

Optionally, the information associated with the second beam includes at least one of: first reference signal information, second reference signal information, third reference signal information, first TCI information, and second TCI information.

In some embodiments, the association between the second beam information and at least one of the following is determined according to at least one of a higher layer parameter configuration, the network device indication, and a predefined manner: first reference signal information, second reference signal information, third reference signal information, first TCI information, and second TCI information.

As an example, the network device configures the second beam information to be associated with the first TCI information or the second reference signal information through higher layer parameters. Alternatively, the network device configures the second beam information to be associated with the second TCI information or the third reference signal information through higher layer parameters. Alternatively, the network device configures the second beam information to be associated with the first reference signal information by higher layer parameters.

In some embodiments, if the second beam information has an association relationship with the first reference signal information, the terminal device determines the second beam information according to the corresponding relationship of the receiving and transmitting beams, so as to determine a beam used in a channel access process corresponding to the response information transmission.

In some embodiments, if the terminal device cannot acquire the second beam information, or the terminal device is not provided with the second beam information, the terminal device determines that the channel access mode corresponding to the response information corresponds to omni-directional channel detection.

And fifthly, the terminal equipment determines response resource information.

In some embodiments, the acknowledgement resource indication information is used to determine at least one of the following information: resource information, time domain position information, downlink allocation indication information and power control information.

In some embodiments, the determining of the response resource indication information includes at least one of: determined from higher layer parameters, indicated by the network device and predefined.

In some embodiments, the reply resource includes one of: PUCCH resources, PRACH resources, SRS resources, and PUSCH resources.

The following is an example in which the acknowledgement resource is a PUCCH resource.

In an example, the resource information of the PUCCH resource may be determined according to a higher layer parameter and/or a manner indicated by the network device. For example, the network device configures a plurality of PUCCH resource information by the higher layer parameter, and instructs the terminal device which PUCCH resource of the plurality of PUCCH resources corresponding to the plurality of PUCCH resource information to use to transmit the response information by the resource information in the response resource instruction information included in the first control information. For another example, if the network device configures one PUCCH resource information by the higher layer parameter, the terminal device transmits the response information using the PUCCH resource determined according to the PUCCH resource information. In this case, the acknowledgement resource indication information in the first control information may not include the resource information.

In an example, the resource information of the PUCCH resource may be predefined, e.g. agreed by a protocol.

In an example, the time domain location information of the PUCCH resource may be determined according to predefined, higher layer parameters and/or a manner indicated by the network device. For example, the higher-layer parameter configuration or the predefined HARQ feedback timing set includes a plurality of K1 values, and the network device instructs the terminal device, through time domain position information (e.g., HARQ feedback timing indication information) in acknowledgement resource indication information included in the first control information, which K1 value of the plurality of K1 values is used to determine the time domain position of the PUCCH resource. For another example, if the higher-layer parameter configuration or the predefined HARQ feedback timing set includes a K1 value, the terminal device determines the time domain position of the PUCCH resource according to the K1 value. In this case, the acknowledgement resource indication information in the first control information may not include time domain location information (e.g., HARQ feedback timing indication information).

In an example, the time domain location information of the PUCCH resource may be predefined, e.g. agreed by a protocol. For example, an interval between the time domain position of the acknowledgement resource and the time domain position of the first control information is predefined as a preset value Ka. If the terminal equipment receives the first control information on the time slot n, the terminal equipment shall send corresponding response information on the time slot n+ka. Or if the terminal device receives the first control information on the time slot n, the location of the response resource is the first available response resource after the interval value condition is met, for example, the time slot n+ka.

In some embodiments, the acknowledgement resource indication information in the first control information includes downlink allocation indication information including C-DAI information and/or T-DAI information, where the C-DAI information and/or T-DAI information is used to determine a location of the acknowledgement information in a feedback codebook.

In some embodiments, the acknowledgement resource indication information in the first control information includes power control information (e.g. TPC command for scheduled PUCCH), from which the terminal device can determine the transmit power at which to transmit the acknowledgement information.

And step six, the terminal equipment determines the content of the response information.

In some embodiments, the acknowledgement information may be carried in at least one of the following channels: PUCCH, PRACH, SRS and PUSCH.

In some embodiments, the uplink shared channel UL-SCH is not included in the PUSCH carrying acknowledgement information.

In some embodiments, the acknowledgement information comprises HARQ-ACK information, or the acknowledgement information comprises only ACK information. Wherein the HARQ-ACK information includes ACK information or NACK information.

In some embodiments, an ACK indicates that transmission is allowed, and a NACK indicates that transmission is not allowed.

In some embodiments, the acknowledgement information includes 1-bit HARQ-ACK information or 1-bit ACK information.

In some embodiments, the 1-bit acknowledgement information is transmitted over PUCCH format 0.

In some embodiments, the request-response procedure initiated by the network device to the terminal device corresponds to at least one frequency domain resource in a first frequency domain resource, the number of bits included in the response information is determined according to the number of frequency domain resources included in the first frequency domain resource, or the number of bits included in the response information is determined according to the number of frequency domain resources in the at least one frequency domain resource.

It should be understood that the defining and determining manners of the first frequency domain resource and at least one frequency domain resource in the first frequency domain resource corresponding to the request-response procedure are as described above, and are not described herein.

As an example, the first frequency domain resource includes M frequency domain resources, K of the M frequency domain resources correspond to a request-response process initiated by the network device to the terminal device, K is an integer less than or equal to M and greater than or equal to 0, and the response information includes M bits, where each bit corresponds to one of the M frequency domain resources. And the response information corresponding to the bit positions corresponding to the K frequency domain resources in the M bits is allowed to be transmitted, and the response information corresponding to other bit positions in the M bits is not allowed to be transmitted.

As an example, the first frequency domain resource includes M frequency domain resources, K of the M frequency domain resources correspond to a request-response process initiated by the network device to the terminal device, K is an integer less than or equal to M and greater than or equal to 0, and the response information includes M bits, where each bit corresponds to one of the M frequency domain resources. And when K is greater than 0, the response information in the bit positions corresponding to the K frequency domain resources in the M bits is allowed to be transmitted correspondingly, and the response information in other bit positions in the M bits is not allowed to be transmitted correspondingly. And when K is 0, the terminal equipment does not send the response information.

As an example, the first frequency domain resource includes M frequency domain resources, K of the M frequency domain resources correspond to a request-response process initiated by the network device to the terminal device, K is an integer less than or equal to M and greater than or equal to 0, and the response information includes K bits, where each bit corresponds to one of the K frequency domain resources. Optionally, the order of the K bits is determined according to downlink allocation indication information, such as C-DAI information and/or T-DAI information.

As an example, the first frequency domain resource is a first set of frequency domain resources on the activated BWP configured by the terminal device, the first set of frequency domain resources comprising at least one set of frequency domain resources, wherein one set of frequency domain resources may be one set of resource blocks RBs. As shown in fig. 6, the active BWP of the terminal device includes 4 RB sets, respectively RB sets 0 to 3. Correspondingly, the response information sent by the terminal equipment comprises 4 bits, which are respectively in one-to-one correspondence with the 4 RB sets. When the terminal device receives transmission request information (denoted by RTS in the figure as an example) associated with RB sets 0 and 1 of the 4 RB sets, response information transmitted by the terminal device to the network device is shown in table 4 below (denoted by CTS in the figure as an example). After receiving the response information sent by the terminal device, the network device may send downlink transmission to the terminal device through the resources in RB sets 0 and 1.

Table 4, response information example

RB set 0	RB set 1	RB set2	RB set 3
ACK	ACK	NACK	NACK

In some embodiments, the acknowledgement information may be carried by a reference signal sequence, such as a PRACH sequence or SRS sequence. When the terminal device sends the reference signal sequence to the network device, the terminal device sends response information allowing transmission to the network device.

In some embodiments, if the terminal device does not receive the first control information, no reply information is sent to the network device.

In some embodiments, if the terminal device does not receive the first control information, NACK information is sent to the network device on a pre-configured or predefined time-frequency resource. For example, in a channel access mechanism where a semi-static channel is occupied, the resources for transmitting acknowledgement information may be pre-configured or pre-defined and occur periodically, in which case NACK information may be transmitted on the corresponding acknowledgement resources if the terminal device does not receive the first control information.

In some embodiments, the first control information is terminal device specific control information, e.g. DCI transmitted via a UE-specific PDCCH.

In some embodiments, the first control information is common or Group common control information, e.g., DCI transmitted over a Group-common PDCCH.

The embodiment of the application can be applied to the terminal equipment to receive the first control information, such as the downlink control information, sent by the network equipment, and determine whether the network equipment requests transmission (or initiates a request-response process) according to the first control information, and correspondingly, the terminal equipment determines whether to send response information to the network equipment. Or, the method may be applied to the network device to receive the first control information, such as the uplink control information, sent by the terminal device, and determine whether the terminal device requests transmission according to the first control information, and accordingly, the network device determines whether to send response information to the terminal device. Or, the first control information, such as the sidestream control information, may be applied in the sidestream transmission from terminal device to terminal device, in which case the first terminal device may receive the first control information sent by the second terminal device and determine whether the second terminal device requests transmission according to the first control information, and accordingly, the first terminal device determines whether to send response information to the second terminal device.

In summary, the embodiment of the application describes a transmission process of response information, which can be used for information interaction in a channel access process assisted by a receiving side. The first control information in the present application may include transmission request information corresponding to the first device. After receiving the transmission request information of the first device included in the first control information, the first device may determine whether to send response information to the second device, and if it is determined to send the response information, send the response information to the second device according to at least one of the determined beam information associated with the transmission of the response information, the channel access mode corresponding to the transmission of the response information, the beam information associated with the channel access mode, the time domain position of the response resource, the resource information, the response information content, and other related information, thereby completing information interaction with the second device.
