To facilitate a better understanding of embodiments of the present application, a description of the related art of the present application will be first provided.
The NR system currently mainly considers two Frequency bands, FR1 (Frequency range 1) and FR2 (Frequency range 2), and as an example, FR1 and FR2 include Frequency domain ranges as shown in table 1.
TABLE 1
Frequency band definition | Corresponding frequency range |
FR1 | 410MHz–7.125GHz |
FR2 | 24.25GHz–52.6GHz |
As NR systems evolve, new frequency bands, such as technologies at high frequencies, are also beginning to be studied. The new frequency band includes the frequency domain ranges shown in table 2, and is denoted by FRX for convenience of description, and it should be understood that the frequency band name should not constitute any limitation. For example, FRX may be FR3.
Table 2: new frequency range
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 (LBT), i.e. the communication device needs to perform channel interception before performing signal transmission on a channel of an unlicensed spectrum, and can perform signal transmission only when the channel interception result is that the channel is idle; if the channel listening result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, 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.
Basic concept of unlicensed spectrum transmission:
maximum Channel Occupancy 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 the 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 mus 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 present application is not limited in this regard.
Channel detection succeeds: also known as LBT success or channel detection idle. For example, the energy detection in the listening slot for the channel is below the energy detection threshold.
Channel detection failure: also known as LBT failure or busy channel detection. For example, the detection of energy in a listening slot for a channel is greater than or equal to an energy detection threshold.
Receiver-side assisted channel access
The receiver side secondary channel listening is an LBT scheme based on a Request To Send/Clear To Send (RTS/CTS) mechanism. As shown in fig. 2. The network device sends a signal similar to RTS to ask the terminal device if it is ready to receive data before transmission. After receiving the RTS signal, if the LBT procedure is successful, the terminal device may send a signal similar to CTS to the network device to report its own interference measurement result, and inform the network device that it is ready to receive data, and the network device may perform downlink transmission to the terminal device after receiving the CTS. Or if the terminal has the receiving equipment and fails to reach the RTS, or the terminal equipment receives the RTS but cannot send the CTS due to failure of the LBT process, the terminal equipment does not send a CTS signal to the network equipment, and the network equipment can give up downlink transmission to the terminal equipment under the condition that the network equipment does not receive the CTS signal of the terminal equipment.
Channel access corresponding to unlicensed spectrum on FRX frequency band
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 the channel access mode without LBT, it may also need to be limited by a certain condition, such as automatic transmit power control ATPC, DFS, long-term interference detection or other interference cancellation mechanism, etc. 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.
After the FRX band is introduced, since the band is relatively high, the LBT pattern on the unlicensed spectrum on the FRX band is different from the LBT pattern on the unlicensed spectrum on the FR1 band. For example, a channel access mode based on the transceiving interaction, also called a receiving side auxiliary channel access mode, may be introduced in the FRX frequency band. Therefore, how to support the access (or detection) of the auxiliary channel at the receiving side in the NR-U system in the FRX band is an urgent problem to be solved.

In some embodiments of the present application, the first device includes a terminal device, the second device includes a network device, and the first control information may be first downlink control information (Downlink Control Information, DCI), where the first DCI corresponds to a first DCI format.
In some embodiments of the present application, the first downlink control information may be transmitted through a physical downlink control channel (Physical Downlink Control Channel, PDCCH), i.e., the first downlink control information may be carried in the PDCCH.
In some embodiments of the present application, the first DCI format includes at least one of the following DCI formats:

In some embodiments of the present application, the first control information may be control information specific to the first device.
For example, the second device is a network device, and the first control information is a first DCI. For example, the first DCI may be carried in a dedicated physical downlink control channel (Physical Downlink Control Channel, PDCCH) of the terminal device.
In other embodiments of the present application, the first control information may be common control information. For example, the first control information may be transmitted through a Group Common (GC) PDCCH.
In further embodiments of the present application, the first control information may also be carried by a physical signal, such as a reference signal. As an example, the above-described process may include: the first device receives a reference signal sent by the second device, wherein the reference signal is used for the first device to determine whether the second device initiates a request-response process to the first device, and the first device determines whether to send response information to the second device according to the reference signal.

if the second device initiates the request-response process to the first device according to the first control information, the first device determines to send response information to the second device; and/or the number of the groups of groups,
And if the second device does not initiate the request-response process to the first device according to the first control information, the first device determines not to send the response information to the second device.
In some embodiments of the present application, the acknowledgement information is used to indicate that transmission is allowed, for example, ACK information.
In some embodiments of the present application, if the first device receives the first control information sent by the second device, the first device determines to send the response information to the second device.
In some embodiments of the present application, if it is determined according to the first control information that the second device does not initiate the request-response procedure to the first device, the first device determines to send the response information to the second device, where the response information is used to indicate that transmission is not allowed, for example, NACK information. In some embodiments of the present application, whether the second device initiates the request-response procedure 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 procedure to the first device.
As another example, if the transmission request information is not included in the first control information, the first device determines that the second device does not initiate the request-response procedure to the first device.
In some embodiments, if the first control information includes transmission request information, the first device may send acknowledgement information to the second device, for example, the acknowledgement information may be ACK. Or if the first control information does not include the transmission request information, the first device may not send response information to the second device, or send response information, where the response information is used to indicate that transmission is not allowed.
In some embodiments, whether the transmission request information is included in the first control information is network device configured. Alternatively, whether the first control information can be used to initiate the request-reply procedure is network device configured.
As an example, the network device may configure, through a higher-layer parameter, whether the first control information includes the transmission request information, or whether the control information format corresponding to the first control information includes an information field corresponding to the transmission request information. For example, the higher-layer parameter takes a first value indicating that the first control information includes transmission request information, and the higher-layer parameter takes a second value indicating that the first control information does not include transmission request information. For another example, if the higher-layer parameter is configured, it indicates that the first control information includes transmission request information, and if the higher-layer parameter is not configured, it indicates that the first control information does not include transmission request information.
In other embodiments, whether the transmission request information is included in the first control information is terminal device configured. Alternatively, whether the first control information can be used to initiate the request-response procedure is terminal device configured.
As an example, the terminal device may configure whether the first control information includes the transmission request information through a higher layer parameter, or the terminal device may configure whether the control information format corresponding to the first control information includes an information field corresponding to the transmission request information through a higher layer parameter. For example, the higher-layer parameter takes a first value indicating that the first control information includes transmission request information, and the higher-layer parameter takes a second value indicating that the first control information does not include transmission request information. For another example, if the higher-layer parameter is configured, it indicates that the first control information includes transmission request information, and if the higher-layer parameter is not configured, it indicates that the first control information does not include transmission request information.
In this case, the first device may be a first terminal device, the second device may be a second terminal device, and the terminal device configured with the higher-layer parameter may be, for example, a third terminal device. The third terminal device may be the first terminal device, or the second terminal device, or a control node of the first terminal device, or a control node of the second terminal device, where the control node of the first terminal device is, for example, a head-group terminal of a terminal group to which the first terminal device belongs, and the control node of the second terminal device is, for example, a head-group terminal of a 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 header terminals corresponding to the first terminal device and the second terminal device are the same terminal device.
In some embodiments, the first control information includes the transmission request information, the first control information corresponding to a first control information format.
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 further include an information field for carrying scheduling information, and with this implementation, it may be possible to send the transmission request information and the scheduling information to the first device simultaneously through the first control information format.
As another implementation, the transmission request information multiplexes existing information fields in the first control information format. The implementation can reduce the control information cost.
As one example, the first control information format is a DCI format for scheduling PDSCH or activating SPS PDSCH transmissions. 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, the terminal device determines to transmit response information to the network device. Further, in the case that the terminal device transmits the acknowledgement 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, the terminal device determines to transmit response information to the network device. Further, in the case that the terminal device transmits the response information to the network device, the terminal device transmits the PUSCH scheduled by the first control information or transmits the CG PUSCH activated by the first control information.
As yet another example, the first control information format is a DCI format for releasing SPS PDSCH or releasing 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, the terminal device determines to transmit response information to the network device. In some embodiments of the present application, the acknowledgement information includes ACK information corresponding to the first control information, for example, the acknowledgement information is used to indicate that the terminal device receives DCI for releasing SPS PDSCH or releasing CG PUSCH and receives the transmission request information. Further, in the case where the terminal device transmits the acknowledgement information to the network device, the terminal device no longer receives the SPS PDSCH or no longer transmits the CG PUSCH.
As yet another example, the first control information format is a DCI format for activating or releasing a configuration grant physical side 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, the terminal device determines to transmit response information to the network device. In some embodiments of the present application, the acknowledgement information includes ACK information corresponding to the first control information, for example, the acknowledgement information is used to indicate that the terminal device receives DCI for activating or releasing configuration grant physical sidelink channels and receives the transmission request information. Further, in the case that the terminal device sends the response information to the network device, the terminal device may start to perform or not perform transmission of the configuration authorized physical sidelink channel with another terminal device.
As yet another example, the first control information format is a SCI format for scheduling PSSCH transmissions. 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, the first terminal device determines to transmit response information to the second terminal device. Further, in the case that the first terminal device transmits 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 for indicating whether the first control information includes the transmission request information, in other words, the format indication information may indicate whether the first control information is used to transmit the transmission request information.
For example, the format indication information includes 1 bit, and when the 1 bit indicates a preset value, for example, "1", the format indication information indicates that the first control information includes transmission request information; when the 1 bit indicates another preset value, for example, "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 transmission request information may be included in DCI format 1_1 in which the network device schedules PDSCH by higher layer parameter configuration, and the format indication information is included in DCI format 1_1. When terminal equipment receives DCI corresponding to DCI format 1_1, if format indication information in the DCI indicates that the DCI comprises transmission request information, the terminal equipment interprets the DCI according to an information field corresponding to the transmission request information; if the format indication information in the DCI indicates that the DCI does not include transmission request information, the terminal equipment interprets the DCI according to the information field corresponding to the scheduling PDSCH.
In other embodiments, whether the second device initiates the request-reply procedure to the first device may be determined based on the content of the transmission request information. For example, when the transmission request information includes a resource for transmitting the response information and related information such as a beam for transmitting the response information, the second device may be considered to initiate the request-response procedure to the first device.
I.e. the transmission request information may be used to determine whether the second device initiates a request-response procedure to the first device and/or the first device sends information about resources, beams, channel access modes etc. of the response information. It should be understood that the resource, beam, channel access mode, and other related information of the response information sent by the first device may be determined by the transmission request information, or may be pre-defined or configured by a high-level parameter, or may be determined in part by the transmission request information, or may be partially pre-defined or configured by a high-level parameter, which is not limited in this application.
The following describes a specific implementation of the transmission request information in conjunction with a specific embodiment, and it should be understood that the following information content is merely an example, but the present application is not limited thereto.
In some embodiments of the present application, the transmission request information includes at least one of the following information:
the method comprises the steps of 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 for indicating whether the request-response process is initiated or not.
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, by a higher layer parameter configuration.
In 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, for example, a third terminal device, for example, configured by a higher-layer parameter.
In this case, the first device is a first terminal device, the second device is a second terminal device, the third terminal device may be the first terminal device, or the second terminal device, or a control node of the first terminal device, or a control node of the second terminal device, where the control node of the first terminal device is, for example, a head-group terminal of a terminal group to which the first terminal device belongs, and the control node of the second terminal device is, for example, a head-group terminal of a 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 header terminals corresponding to the first terminal device and the second terminal device are the same terminal device.
In still other embodiments, the number of bits occupied by the first indication information in the first control information may be predefined.
That is, the first indication information may be configured by a network device corresponding to the first device or configured by a control node having a management control function for the first device, or predefined.
It should be understood that the configuration manners of the beam indication information, the response resource indication information, the signal access indication information, and the frequency domain resource indication information in the first control information are similar to the configuration manners of the first indication information in the first control information in the number of bits occupied by the first indication information, and are not repeated herein for brevity.
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 higher-layer parameter configured by a network device or the third device; or, the number of bits occupied by at least one kind of information included in the transmission request information in the first control information is predefined.
Taking the acknowledgement resource indication information as an example for illustration, for example, if the network device configures the acknowledgement resource indication information to correspond to M states through a higher layer parameter, or the acknowledgement resource indication information is predefined to correspond to M states, the number of bits corresponding to the acknowledgement resource indication information in the first control information format is ceil (log 2 (M)) bits, where log2 represents a logarithm with a base of 2, and ceil represents an upper rounding. 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-reply procedure to the first device.
As an example, the first indication information is 1 bit, and a value of the 1 bit is used to indicate whether the second device initiates the request-response procedure to the first device.
For example, when the 1-bit value is a first preset value, for example, 1, the second device is instructed to initiate the request-response procedure to the first device, and when the 1-bit value is a second preset value, for example, 0, the second device is instructed not to initiate the request-response procedure to the first device.
In this case, the first indication information may be considered to be related to a frequency domain resource associated with the first control information. For example, the first control information is used to schedule or activate physical channels or physical signal transmissions on a first 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 to the first control information to carry the first indication information.
In other embodiments, the first indication information may multiplex an existing information field in the first control information.
As an example, the first control information includes a first information field therein, and the first indication information is characterized 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 that a request-response procedure is not initiated to the first device. For another example, the first information field is used to determine whether to initiate the request-response procedure or the first information field is not used to determine whether to initiate the request-response procedure when the value of the first information field is not the first state. That is, when the value of the first information field is in the first state, the first information field is interpreted according to the first instruction information, and when the first information field is not in the first state, the first information field is interpreted according to the original meaning of the first information field.
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 an information field corresponding to response resource indication information, and if the response resource indication information indicates an invalid response resource, for example, does not indicate a time domain position of the response resource, it indicates that the second device does not initiate the request-response procedure to the first device; or if the response resource indication information indicates an effective response resource, the information domain is interpreted according to the response resource indication information, and the second device initiates the request-response process to the first device, wherein the response resource used in the request-response process is determined according to the effective response resource indicated by the response resource indication information.
As yet another example, the first indication information is characterized by a second state of a value of some or all bits of the first control information. For example, when the value of the part or all of the bits in the first control information is the second state, the first indication information indicates that the request-response process is not initiated, or the first control information indicates that the request-response process is not initiated.
For example, the value of M bits in the first control information may be used as a first status indication, and if all the M bits are "1" or all the M bits are "0", it indicates that the request-response procedure is not initiated to the first device; otherwise, the M bits are interpreted 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 set of frequency domain resources, or each of the at least one frequency domain resource indication information is associated with one cell or one BWP or one set of frequency domain resources. Wherein a first frequency domain resource indication information of the at least one frequency domain resource indication information is associated with a first cell or a first BWP or a first set of frequency domain resources. The first frequency domain resource indication information is used for indicating whether the second device initiates the request-response procedure to the first device on the first cell or the first BWP or the first set of frequency domain resources, or the first frequency domain resource indication information is used for indicating whether to initiate the request-response procedure corresponding to the first cell or the first BWP or the first set of frequency domain resources, or the first frequency domain resource indication information is used for indicating that the response information is associated with the first cell or the first BWP or the first set of frequency domain resources.
In some embodiments of the present application, the first cell is a cell corresponding to the first device, the first BWP is a BWP corresponding to the first cell, and the first set of frequency domain resources is a set of frequency domain resources corresponding to the first 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 associated with a first cell, wherein the first frequency domain resource indication information is used to indicate whether the second device initiates the request-response procedure corresponding to the first cell to the first device.
It is to be understood that said initiating said request-response procedure to said first device corresponding to said first cell may refer to initiating said request-response procedure on said first cell or initiating said request-response procedure on a second cell, wherein the second cell and the first cell have a correspondence.
As an example, the first frequency domain resource indication information is 1 bit, and a value of the 1 bit is used to indicate whether the second device initiates the request-response procedure corresponding to the first cell to the first device. For example, when the 1-bit value is a first preset value, for example, 1, the method is used for indicating the second device to initiate the request-response process corresponding to the first cell to the first device, and when the 1-bit value is a second preset value, for example, 0, the method is used for indicating 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 may be replaced by other frequency domain concepts, such as BWP, or a set of frequency domain resources, etc., which is not limited in this embodiment, that is, the frequency domain resource indication information may be associated with a cell, or with BWP, or with a set of frequency domain resources, etc.
It should also be understood that, in the embodiment of the present application, the beam indication information, the response resource indication information, and the channel access indication information may be associated with the frequency domain resource, or may also be not associated with the frequency domain resource, that is, the embodiment of the present application may configure transmission request information associated with the frequency domain resource, or may also configure transmission request information not associated with the frequency domain resource, so as to enable receiving side auxiliary channel detection with different accuracy.
In some embodiments, the frequency domain resource indication information is carried in a dedicated information domain in the first control information. For example, an information field may be added to the first control information to carry the frequency domain resource indication information.
In other embodiments, the frequency domain resource indication information may multiplex an existing information domain 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 indicate that the second device does not initiate a request-response procedure corresponding to the associated cell or BWP or frequency domain resource set to the first device. For another example, the second information field is not used to determine whether to initiate the request-response procedure when the value of the second information field is not the first state. 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 a second device initiates a request-response procedure corresponding to an associated cell or BWP or a set of frequency domain resources to the first device.
Namely, when the value of the second information field is in the first state, the first information field is interpreted according to the frequency domain resource indication information, and when the second information field is not in the first state, the first information field is interpreted according to the original definition of the second information field.
For example, the second information field is an information field corresponding to response resource indication information, and includes N bits, and if the N bits are all "1" or all "0", it indicates that the second device does not initiate the request-response procedure corresponding to the associated cell or BWP or frequency domain resource set to the first device; otherwise, the information domain is interpreted 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 a second state indication by a value of a part or all bits of the first control information. For example, when the value of the part or all of the bits in the first control information is the second state, it indicates that the second device does not initiate the request-response procedure to the first device corresponding to the associated cell or BWP or frequency domain resource set.
Taking frequency domain resource indication information associated BWP as an example. As one example, the terminal device is configured with N BWP, and the frequency domain resource indication information includes N bits, each corresponding to one BWP. When a certain bit indicates a preset value, for example, "1", for indicating initiation of a request-response procedure corresponding to the BWP; when a certain bit indicates another preset value, e.g. "0", is used to indicate that a request-response procedure corresponding to the BWP is not initiated, where N is a positive integer.
As yet another example, the terminal device is configured with N BWP, the first control information is transmitted through a first BWP of the N BWP, and the frequency domain resource indication information includes N-1 bits, each of which corresponds to one BWP of the N BWP other than the first BWP. When a certain bit indicates a preset value, for example, "1", for indicating initiation of a request-response procedure corresponding to the BWP; when a certain bit indicates another preset value, e.g. "0", it is used to indicate that a request-response procedure corresponding to the BWP is not initiated.
For this first BWP, whether to initiate the request-reply procedure may be implicitly indicated.
In some embodiments of the present application, the beam indication information is used to determine at least one of the following information: the first beam information associated with the first control information, the second beam information associated with physical channel transmission and the third beam information associated with the response information. For example, the beam indication information is used to determine at least one of the following information: the first control information is related to first reference signal information, the second reference signal information related to physical channel transmission and the third reference signal information related to response information.
In some embodiments of the present application, the beam information may be replaced with reference signal information or reference signal index or TCI information.
In some embodiments, the first beam information associated with the first control information may be beam information for transmitting the first control information or beam information for determining a transmission beam of the first control information. Alternatively, the first beam information associated with the first control information may be information of a first reference signal having a quasi co-located QCL relationship with the first control information or a physical channel or physical signal carrying the first control information, for example, an index of the first reference signal or first TCI information.
In some embodiments, the physical channel carrying the first control information may be a PDCCH, PUCCH or physical sidelink control channel, such as PSCCH.
In some embodiments, the physical signal carrying the first control information may be SSB, CSI-RS or SRS or a physical sidelobe signal, for example, a sidelobe CSI-RS or a Phase-tracking reference signal (Phase-tracking reference signals, PT-RS), etc.
In some embodiments, the second beam information associated with the physical channel may be beam information for transmitting the physical channel. For example, the beam used for transmitting the physical channel may be determined from the second beam information associated with the physical channel. Alternatively, the second beam information associated with the physical channel may be information of a second reference signal having a QCL relationship with the physical channel such as an index of the second reference signal or second TCI information.
