To facilitate a better understanding of the embodiments of the present application, the related technologies of the present application are described first.

The NR system currently mainly considers two frequency bands, FR1 (Frequency range 1) and FR2 (Frequency range 2). As an example, the frequency domain ranges included in FR1 and FR2 are shown in Table 1.

Table 1

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

With the evolution of NR systems, new frequency bands such as high-frequency technologies have also begun to be studied. The frequency domain range included in the new frequency band is shown in Table 2. For the convenience of description, it is represented by FRX in this application. It should be understood that the name of the frequency band should not constitute any limitation. For example, FRX could be FR3.

Table 2: New frequency band range

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

The FRX frequency band includes licensed spectrum and unlicensed spectrum. In other words, the FRX frequency band includes non-shared spectrum or dedicated spectrum, and also includes shared spectrum.

The unlicensed spectrum is the spectrum allocated by the country and region that can be used for radio device communication. This spectrum is usually considered a shared spectrum, that is, communication devices in different communication systems can be used as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply to the government for exclusive spectrum authorization.

In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, the communication device follows the "listen before talking (LBT)" principle, that is, the communication device needs to perform channel detection before sending signals on the channel of the unlicensed spectrum. Only when the channel detection result indicates that the channel is idle, the Only the communication device can send the signal; if the result of the channel detection of the communication device on the channel of the unlicensed frequency spectrum is that the channel is busy, the communication device cannot send the signal. For another example, in order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the channel of the unlicensed spectrum cannot exceed a certain period of time. For another example, in order to prevent the power of the signal transmitted on the channel of the unlicensed spectrum from being too large and affecting the transmission of other important signals on the channel, the communication device needs to follow the maximum power spectrum when using the channel of the unlicensed spectrum for signal transmission. Density limitations. It should be noted that in some countries or regions, there is no LBT requirement for the unlicensed spectrum included in the FRX frequency band.

Basic concepts of transmission on unlicensed spectrum:

Maximum channel occupancy time (MCOT): refers to the maximum length of time allowed to use the channel for signal transmission after successful channel sensing on the shared spectrum channel.

Channel occupancy time (Channel Occupancy Time, COT): refers to the length of time that the channel is used for signal transmission after successful channel detection on the shared spectrum channel. length of time. Wherein, the channel occupied by the signal within the time length may be continuous or discontinuous, and the time length includes the total time for signal transmission by the device initiating the channel occupation and the device occupied by the shared channel.

Channel occupancy time of network equipment (gNB/eNB-initiated COT): also known as COT initiated by network equipment, refers to a channel occupancy time obtained by a network equipment after successful channel detection on a shared spectrum channel. The COT initiated by the network device can not only be used for network device transmission, but also can be used for terminal device transmission under certain conditions.

UE-initiated channel occupancy time (UE-initiated COT): also called UE-initiated COT, refers to the channel occupancy time obtained by the terminal equipment after successful channel detection on the channel of the shared spectrum. The COT initiated by the terminal device can not only be used for transmission by the terminal device, but also can be used by the network device for transmission if certain conditions are met.

Downlink transmission opportunity (DL transmission burst): A group of downlink transmissions performed by network equipment (that is, including one or more downlink transmissions), the group of downlink transmissions is continuous transmission (that is, there is no gap between multiple downlink transmissions), or the group There is a gap in the downlink transmission but the gap is less than or equal to a preset value, for example, the preset value is 16 μs on the FR1 frequency band. If the gap between two downlink transmissions performed by the network device is greater than the preset value of 16 μs, 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 performed by a terminal device (that is, including one or more uplink transmissions), and the group of uplink transmissions is continuous transmission (that is, there is no gap between multiple uplink transmissions), or the There is a gap in the group uplink transmission but the gap is less than or equal to a preset value, for example, the preset value is 16 μs on the FR1 frequency band. If the gap between the two uplink transmissions performed by the terminal device is greater than the preset value of 16 μs, it is considered that the two uplink transmissions belong to two uplink transmission opportunities.

It should be understood that, in the FRX frequency band, the foregoing preset value may be other values, such as 8 μs. This application is not limited to this.

Channel detection success: also known as LBT success or channel detection idle. For example, the energy detection performed on the channel in the listening time slot is lower than the energy detection threshold.

Channel detection failure: also known as LBT failure or channel detection busy. For example, the energy detection performed on the channel in the listening time slot is higher than or equal to the energy detection threshold.

Receiver-assisted channel access

Auxiliary channel monitoring at the receiving side is an LBT method based on a Request To Send/Clear To Send (RTS/CTS) mechanism. as shown in picture 2. Before the network device transmits, it first sends a signal similar to RTS to ask the terminal device whether it is ready to receive data. After the terminal device receives the RTS signal, if the LBT process is successful, it can send a signal similar to CTS to the network device, such as reporting its own interference measurement results, informing the network device that it is ready to receive data. After the CTS, downlink transmission can be performed to the terminal equipment. Or, if the receiving device of the terminal does not receive the RTS, or the terminal device receives the RTS but cannot send the CTS due to the failure of the LBT process, the terminal device will not send the CTS signal to the network device, and the network device does not receive the CTS signal of the terminal device. In this case, the downlink transmission to the terminal equipment may be abandoned.

Channel access corresponding to unlicensed spectrum on the FRX frequency band

On the FRX frequency band, for countries and regions that require LBT, the LBT method (that is, the channel access method) can include omnidirectional LBT, directional LBT, auxiliary LBT on the receiving side, and no LBT. Among them, for channel access methods without LBT, certain conditions may also need to be limited, such as automatic transmit power control ATPC, DFS, long-term interference detection or other interference elimination mechanisms. In addition, it is also possible to switch between channel access with LBT and channel access without LBT.

For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply DFS, apply ATPC, apply long-term interference detection, limit a certain duty cycle (duty cycle), limit a certain transmit power, limit MCOT etc.

After the introduction of the FRX frequency band, due to the relatively high frequency band, the LBT method on the unlicensed spectrum on the FRX frequency band is different from the LBT method on the unlicensed spectrum on the FR1 frequency band. For example, a channel access method based on transceiving interaction can be introduced in the FRX frequency band, which is also called an auxiliary channel access method on the receiving side. Therefore, how to support the receiving-side auxiliary channel access (or called receiving-side auxiliary channel detection, receiving-side auxiliary LBT) method in the NR-U system on the FRX frequency band is an urgent problem to be solved.

In some embodiments of the present application, whether the second device initiates the request-response process to the first device may be determined according to whether the first control information includes transmission request information.

As an example, if the first control information includes the transmission request information, the first device determines that the second device initiates the request-response process to the first device.

As another example, if the first control information does not include the transmission request information, the first device determines that the second device does not initiate the request-response process to the first device.

In some embodiments, if the first control information includes transmission request information, the first device may send response information to the second device, for example, the response information may be an ACK.

As an example, the network device may configure whether the first control information includes the transmission request information through a high-level parameter, or, the network device may configure whether the control information format corresponding to the first control information includes the The information field corresponding to the transmission request information. For example, the high layer parameter takes a first value, indicating that the first control information includes transmission request information, and the high layer parameter takes a second value, indicating that the first control information does not include transmission request information. For another example, if the high-layer parameter is configured, it means that the first control information includes transmission request information; if the high-layer parameter is not configured, it means that the first control information does not include transmission request information.

In some other embodiments, whether the first control information includes the transmission request information is configured by the terminal device. Alternatively, whether the first control information can be used to initiate the request-response process is configured by the terminal device.

The information field corresponding to the transmission request information. For example, the high layer parameter takes a first value, indicating that the first control information includes transmission request information, and the high layer parameter takes a second value, indicating that the first control information does not include transmission request information. For another example, if the high-layer parameter is configured, it means that the first control information includes transmission request information; if the high-layer parameter is not configured, it means that the first control information does not include transmission request information.

In this case, the first device is a first terminal device, the second device may be a second terminal device, and the terminal device configured with high layer parameters may be, for example, a third terminal device. The third terminal device may be the first terminal device, or the second terminal device, or the control node of the first terminal device, or the control node of the second terminal device, the The control node of the first terminal device is, for example, the head terminal of the terminal group to which the first terminal device belongs, and the control node of the second terminal device is, for example, the group head terminal of the terminal group to which the second terminal device belongs.

In some cases, the third terminal device and the second terminal device may be the same terminal device. In other cases, the third terminal device and the first terminal device may be the same terminal device, and the group head terminals corresponding to the first terminal device and the second terminal device are the same terminal device.

As an implementation manner, the first control information format may include an information field for carrying the transmission request information, that is, the transmission request information corresponds to a dedicated information field in the first control information field. In some embodiments, the first control information format may also include an information field for carrying scheduling information. With this implementation, the transmission request information and scheduling information may be simultaneously sent to the first device through the first control information format. .

As another implementation manner, the transmission request information multiplexes existing information fields in the first control information format. Adopting this implementation manner can reduce control information overhead.

As an example, the first control information format is a DCI format used for scheduling PDSCH or activating SPS PDSCH transmission. The first device is a terminal device, and the second device is a network device. If the terminal device receives the first control information including the transmission request information, then the terminal device determines to send response information to the network device. Further, when the terminal device sends the response information to the network device, the terminal device receives the PDSCH scheduled by the first control information or receives the SPS PDSCH activated by the first control information.

As another example, the first control information format is a DCI format for scheduling PUSCH or activating CG PUSCH transmission. The first device is a terminal device, and the second device is a network device. If the terminal device receives the first control information including the transmission request information, then the terminal device determines to send response information to the network device. Further, when the terminal device sends the response information to the network device, the terminal device sends the PUSCH scheduled by the first control information or sends the CG PUSCH activated by the first control information.

As yet another example, the first control information format is a DCI format for releasing the SPS PDSCH or releasing the CG PUSCH. The first device is a terminal device, and the second device is a network device. If the terminal device receives the first control information including the transmission request information, then the terminal device determines to send response information to the network device. In some embodiments of the present application, the response information includes ACK information corresponding to the first control information, for example, the response information is used to indicate that the terminal device has received the DCI for releasing the SPS PDSCH or releasing the CG PUSCH And the transmission request information is received. Further, when the terminal device sends the response information to the network device, the terminal device no longer receives the SPS PDSCH or no longer sends the CG PUSCH.

As yet another example, the first control information format is a DCI format for activating and configuring the authorized physical sidelink channel or releasing the configured and authorized physical sidelink channel. The first device is a terminal device, and the second device is a network device. If the terminal device receives the first control information including the transmission request information, then the terminal device determines to send response information to the network device. In some embodiments of the present application, the response information includes ACK information corresponding to the first control information, for example, the response information is used to indicate that the terminal device has received DCI and received the transfer request message. Further, in the case that the terminal device sends the response information to the network device, the terminal device may start or stop performing the transmission of the configured authorized physical side channel with another terminal device.

As yet another example, the first control information format is an SCI format for scheduling PSSCH transmission. The first device is a first terminal device, and the second device is a second terminal device. If the first terminal device receives the first control information including the transmission request information, then the first terminal device determines to send response information to the second terminal device. Further, when the first terminal device sends the response information to the second terminal device, the first terminal device receives the PSSCH scheduled by the first control information.

In some embodiments, the first control information includes format indication information, and the format indication information is used to indicate whether the first control information includes the transmission request information. In other words, the format indication information may indicate that the first Whether the control information is used to send the transmission request information.

For example, the format indication information includes 1 bit, and when the 1 bit indicates a preset value such as "1", it is used to indicate that the first control information includes transmission request information; when the 1 bit indicates another preset value such as " When 0", the format indication information is used to indicate that the first control information does not include transmission request information.

As an example, it is assumed that the DCI format 1_1 in which the network device schedules the PDSCH through high layer parameter configuration may include the transmission request information, and the DCI format 1_1 includes the format indication information. When the terminal device receives DCI corresponding to DCI format 1_1, if the format indication information in the DCI indicates that the DCI includes transmission request information, the terminal device interprets the DCI according to the information field corresponding to the transmission request information; if the DCI contains The format indication information indicates that the DCI does not include transmission request information, and the terminal device interprets the DCI according to the information field corresponding to the scheduled PDSCH.

In some other embodiments, whether the second device initiates the request-response process to the first device may be determined according to content of the transmission request information. For example, the transmission request information includes resources for transmitting the response information, and when transmitting related information such as a beam of the response information, it may be considered that the second device initiates the request-response process to the first device.

That is, the transmission request information may be used to determine whether the second device initiates a request-response process to the first device, and/or related information such as resources, beams, and channel access methods for sending response information by the first device. It should be understood that the resource, beam, channel access mode and other related information for the first device to send the response information may be determined through the transmission request information, or may be predefined or configured by high-level parameters, or may be partially determined through the transmission request information. It is determined by the above transmission request information, part of which is predefined or configured by high-level parameters, which is not limited in this application.

The specific implementation of the transmission request information will be described below in conjunction with specific embodiments. It should be understood that the following information content is only an example, but the application is not limited thereto.

First indication information, at least one frequency domain resource indication information, beam indication information, response resource indication information and channel access indication information, wherein the first indication information is used to indicate whether to initiate the request-response process.

In some embodiments, the number of bits occupied by the first indication information in the first control information is configured by a network device, for example, configured through a high-level parameter.

In some other embodiments, the number of bits occupied by the first indication information in the first control information is configured by a third device having a management control function, such as a third terminal device, for example, through high-level parameter configuration.

In some cases, the third terminal device and the second terminal device may be the same terminal device. In other cases, the third terminal device and the first terminal device may be the same terminal device, and the group head terminals corresponding to the first terminal device and the second terminal device are the same terminal device.

In some other embodiments, the number of bits occupied by the first indication information in the first control information may also be predefined.

That is, the first indication information may be configured by a network device corresponding to the first device or by a control node having a management control function for the first device, or may be predefined.

It should be understood that the configuration mode of the number of bits occupied by the beam indication information, the response resource indication information, the channel access indication information, and the frequency domain resource indication information in the first control information and the first indication information The configuration manner of the number of bits occupied in the first control information is similar, and for the sake of brevity, details are not repeated here.

That is, the number of bits occupied by at least one type of information included in the transmission request information in the first control information is determined according to a high-level parameter configured by the network device or the third device; or, the transmission request The number of bits occupied by at least one type of information included in the information in the first control information is predefined.

Taking the response resource indication information as an example, for example, assuming that the network device configures the response resource indication information to correspond to M states through high-layer parameters, or the response resource indication information is predefined to correspond to M types of states, then the response resource indication information is in the first The corresponding number of bits in the control information format is ceil(log2(M)) bits, where log2 represents a logarithm with base 2, and ceil represents rounding up. For example, M=8, and the corresponding number of bits is 3 bits.

In some embodiments, the first indication information is used to indicate whether the second device initiates the request-response process to the first device.

As an example, the first indication information is 1 bit, and the value of the 1 bit is used to indicate whether the second device initiates the request-response process to the first device.

For example, when the value of the 1 bit is a first preset value such as 1, it is used to instruct the second device to initiate the request-response process to the first device, and the value of the 1 bit is a second preset value. When the value is set to 0, for example, it is used to indicate that the second device does not initiate the request-response process to the first device.

In this case, it may be considered that the first indication information is related to the frequency domain resource associated with the first control information. For example, the first control information is used to schedule or activate physical channel or physical signal transmission on a first bandwidth part (Bandwidth Part, BWP), and the first indication information is associated with the first BWP.

In some embodiments, the first indication information is carried in a dedicated information field in the first control information. For example, an information field may be added in the first control information to bear the first indication information.

In other embodiments, the first indication information may reuse existing information fields in the first control information.

As an example, the first control information includes a first information field, and the first indication information is represented by a first state of the first information field in the first control information. For example, when the value of the first information field is the first state, the first information field is used to indicate not to initiate a request-response process to the first device. For another example, when the value of the first information field is not the first state, the first information field is used to determine whether to initiate the request-response process, or the first information field is not used to determine whether to initiate The request-response process. That is, when the value of the first information field is the first state, the first information field is interpreted according to the first indication information; when the first information field is not in the first state, the original meaning of the first information field is interpreted.

In some embodiments of the present application, the first state may be an invalid state, or a reserved state.

In some embodiments of the present application, the first information field includes at least one information field.

For example, the first information field is the information field corresponding to the response resource indication information. If the response resource indication information indicates an invalid response resource, for example, does not indicate the time domain position of the response resource, it means that the second device has not sent the response resource to the first device. Initiate the request-response process; or, if the response resource indication information indicates a valid response resource, it means that the information field is interpreted according to the response resource indication information, and the second device initiates the request-response process to the first device A response process, wherein the response resources used in the request-response process are determined according to the effective response resources indicated by the response resource indication information.

As yet another example, the first indication information is represented by a value of some or all bits of the first control information being in the second state. For example, when the values of some or all of the bits in the first control information are the second state, the first indication information indicates not to initiate the request-response process, or in other words, the first A control message indicates not to initiate the request-response procedure.

For example, the values of the M bits in the first control information can be used as the first status indication, and if the M bits are all "1" or "0", it indicates that no The request-response process; otherwise, interpret the M bits normally.

In some embodiments of the present application, the at least one frequency domain resource indication information is associated with at least one cell or at least one BWP or at least one frequency domain resource set, or in other words, each frequency domain resource indication information in the at least one frequency domain resource indication information The domain resource indication information is associated with a cell or a BWP or a frequency domain resource set. Wherein, the first frequency domain resource indication information in the at least one frequency domain resource indication information is associated with the first cell or the first BWP or the first frequency domain resource set. The first frequency domain resource indication information is used to indicate whether the second device initiates the request to the first device on the first cell or the first BWP or the first frequency domain resource set - a response process, or, the first frequency domain resource indication information is used to indicate whether to initiate a request-response process corresponding to the first cell or the first BWP or the first frequency domain resource set, or, The first frequency domain resource indication information is used to indicate that the response information is associated with the first cell or the first BWP or the first frequency domain resource set.

In some embodiments of the present application, the first cell is the cell corresponding to the first device, the first BWP is the BWP corresponding to the first cell, and the first frequency domain resource set is the first A set of frequency domain resources corresponding to a BWP. For example, the first BWP is an active BWP.

For example, the at least one frequency domain resource indication information includes first frequency domain resource indication information, and the first frequency domain resource indication information is associated with the first cell, where the first frequency domain resource indication information is used to indicate the Whether the second device initiates the request-response process corresponding to the first cell to the first device.

It should be understood that the initiating the request-response process corresponding to the first cell to the first device may refer to initiating the request-response process on the first cell, or initiating the request-response process on the second cell The above request-response process, wherein the second cell has a corresponding relationship with the first cell.

As an example, the first frequency domain resource indication information is 1 bit, and the value of the 1 bit is used to indicate whether the second device initiates the first device corresponding to the first cell to the first device. request-response process. For example, when the value of the 1 bit is a first preset value such as 1, it is used to instruct the second device to initiate the request-response process corresponding to the first cell to the first device, the When the value of 1 bit is a second preset value such as 0, it is used to instruct the second device to initiate the request-response process corresponding to the first cell to the first device.

It should be understood that, in the above example, the first cell can also be replaced by other frequency domain concepts, such as BWP, or a frequency domain resource set, etc., which is not limited in this embodiment of the present application, that is, the frequency domain resource indication information can be related to the cell Associated, or associated with the BWP, or associated with the frequency domain resource set, etc.

It should also be understood that in this embodiment of the present application, the beam indication information, response resource indication information, and channel access indication information may be associated with frequency domain resources, or may not be associated with frequency domain resources, that is, this In the embodiment of the application, transmission request information associated with frequency domain resources may be configured, or transmission request information not associated with frequency domain resources may be configured, so as to realize auxiliary channel detection at the receiving side with different accuracy.

In some embodiments, the frequency domain resource indication information is carried in a dedicated information field in the first control information. For example, an information field may be added in the first control information to carry the frequency domain resource indication information.

In some other embodiments, the frequency domain resource indication information may reuse an existing information field in the first control information.

As an example, the first control information includes a second information field, and the frequency domain resource indication information is indicated by a first state of the second information field in the first control information.

For example, when the value of the second information field is the first state, the second information field is used to instruct the second device not to initiate an associated cell or BWP or frequency domain resource to the first device. The set corresponds to the request-response process. For another example, when the value of the second information field is not the first state, the second information field is not used to determine whether to initiate the request-response process. For another example, when the value of the second information field is not the first state, the second information field is used to determine that the second device initiates an associated cell or BWP or frequency domain resource to the first device. The set corresponds to the request-response process.

That is, when the value of the second information field is the first state, the first information field is interpreted according to the frequency domain resource indication information; when the second information field is not in the first state, it is interpreted according to the original definition of the second information field.

For example, the second information field is the information field corresponding to the response resource indication information, including N bits, and if the N bits are all "1" or "0", it means that the second device does not send the A device initiates the request-response process corresponding to the associated cell or BWP or frequency domain resource set; otherwise, it means interpreting the information field according to the response resource indication information.

In some embodiments of the present application, the first state may be an invalid state, or a reserved state.

As yet another example, the frequency domain resource indication information is indicated by a value of some or all bits of the first control information as a second state indication. For example, when the value of some or all of the bits in the first control information is the second state, it means that the second device does not send information to the second state corresponding to the associated cell or BWP or frequency domain resource set. A device initiates the request-response procedure.

Take the BWP associated with the frequency domain resource indication information as an example. As an example, if the terminal device is configured with N BWPs, the frequency domain resource indication information includes N bits, where each bit corresponds to one BWP. When a certain bit indicates a preset value such as "1", it is used to indicate that the request-response process corresponding to the BWP is initiated; when a certain bit indicates another preset value such as "0", it is used to indicate that the BWP is not initiated. It should be the request-response process of BWP, where N is a positive integer.

As another example, the terminal device is configured with N BWPs, and the first control information is transmitted through the first BWP in the N BWPs, then the frequency domain resource indication information includes N-1 bits, and each bit corresponds to the N A BWP other than the first BWP among the BWPs. When a certain bit indicates a preset value such as "1", it is used to indicate that the request-response process corresponding to the BWP is initiated; when a certain bit indicates another preset value such as "0", it is used to indicate that the BWP is not initiated. It should be the request-response process of BWP.

For the first BWP, whether to initiate a request-response process may be indicated implicitly.
