A terminal device arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

Fig. 1 exemplarily shows one network device and two terminal devices, and in one embodiment, the communication system 100 may include a plurality of network devices and each network device may include other numbers of terminal devices within a coverage area thereof, which is not limited in this embodiment of the present application.

In an embodiment, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

Fig. 2 is a schematic flow chart of a communication method 200 according to an embodiment of the present application, wherein the method may be performed by a terminal device. The method 200 includes at least some of the following.

It should be understood that the method of the embodiment of the present application may be applied to unlicensed spectrum communication, and may also be applied to other communication scenarios, such as a communication scenario of licensed spectrum.

Unlicensed spectrum is a spectrum that is divided by countries and regions and available for radio device communications, and may be considered a shared spectrum, i.e., a spectrum that may be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, and no proprietary spectrum license may be applied to the government. In order to enable each communication system using the unlicensed spectrum for wireless communication to coexist friendly on the spectrum, when the communication device performs communication without the license, the principle of Listen Before Talk (LBT) may be followed, that is, Before the communication device performs signal transmission on the channel of the unlicensed spectrum, the communication device needs to perform channel sensing (or called channel detection) first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the communication device performs channel sensing on the unlicensed spectrum, the channel sensing result is that the channel is busy, and signal transmission cannot be performed. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the unlicensed spectrum Channel may not exceed a Maximum Channel Occupancy Time (MCOT).

With the development of wireless communication technology, the NR system may be networked over an unlicensed spectrum to transmit data traffic using the unlicensed spectrum.

In 210, the terminal device receives a downlink control signaling sent by the network device, where the downlink control signaling includes a first information field and a second information field.

The first information field may be referred to as a feedback timing information field (HARQ-timing-indicator), for example, (PDSCH-to-HARQ-timing-indicator), and the second information field may be referred to as a Physical Uplink Control Channel (PUCCH) resource indication information field (PUCCH resource indicator) and/or a PUCCH power adjustment information field (TPC command for scheduled PUCCH).

The value of the first information field may include a first value and a second value.

In one embodiment, in the present application, the first value may be greater than or equal to the first threshold value and less than or equal to the second threshold value. Illustratively, the first threshold value may be 0 and the second threshold value may be 16, i.e., the first value may be an integer from 0 to 16.

The second value may be greater than or equal to the third threshold, or less than or equal to the fourth threshold, or infinity, or infinitesimal.

The first threshold, the second threshold, the third threshold, and the fourth threshold may be specified by a protocol, or may be configured by a network device, which is not specifically limited in this embodiment of the application.

In one embodiment, the second value is different from the first value. For example, when the first value is 4, the second value may be 1. Alternatively, when the first value is 16, the second value may be infinite.

In this embodiment, the first value may represent a time unit in which the first feedback information is located. The time unit may be a subframe, a slot, a time domain symbol, or a Short Transmission Timing Interval (sTTI).

If the downlink control signaling schedules the data channel, the first value may indicate a time interval between an end position of the data channel and a start position of the first feedback information. For example, if the first value is 4, it may indicate that the first feedback information is transmitted in the 4 th time unit after a Physical Downlink Shared Channel (PDSCH) scheduled by the Downlink control signaling.

The first value may indicate a time interval between the downlink control signaling and the first feedback information if the downlink control signaling does not schedule the data channel. For example, if the first value is 4, it may indicate that the first feedback information is transmitted at the 4 th time unit after the downlink control signaling.

As an example, at least five bits in the downlink control signaling may be used to indicate a value of the first information field. Next, a value of the first information field indicated by five bits in the downlink control signaling is described as an example. If the five bits are "0 xxxx", the value of the first information field is a first value, and if the five bits are "1 xxxx", the value of the first information field is a second value. Under the condition that the value of the first information field is the first value, the terminal device may further determine the time unit where the first feedback information is located according to the five bits. For example, if the five bits are "01111", it may indicate that the first feedback information is transmitted at the 16 th time unit after the data channel scheduled by the downlink control signaling; if the five bits are "00110," it can be indicated that the first feedback information is transmitted at the 6 th time unit after the data channel scheduled by the downlink control signaling.

As another example, 1 to 3 bits of the downlink control signaling may be used to indicate a value of the first information field. The number of bits indicating the value of the first information field may be configured by the network device.

Exemplarily, if 3 bits of the downlink control signaling are used to indicate a value of the first information field, the table 1 may be specifically referred to for a corresponding relationship between the bits and the value of the first information field.

TABLE 1

Bit position	Value of the first information field
		000	1
001	2
		010	3
011	4
		100	5
101	6
		110	8
111	∞

In an embodiment, a unit of the value of the first information field may be a time slot, which indicates that the first feedback information is transmitted on the time slot corresponding to the value of the first information field.

In one embodiment, the correspondence between the bits in table 1 and the values of the first information field may be semi-statically configured by the network device. The network device may send a Radio Resource Control (RRC) signaling to the terminal device, where the RRC signaling indicates a corresponding relationship between a bit of the downlink Control signaling and a value of the first information field, and after receiving the RRC signaling and the downlink Control signaling, the terminal device may determine the value of the first information field.

In one embodiment, the correspondence between the bits in table 1 and the values of the first information field may be preset on the terminal device based on a protocol.

It should be understood that the correspondence between the values of the bit and the first information field in table 1 is only an example, but the present application is not limited thereto. For example, the bit "000" may correspond to the value of the first information field being infinitesimal, and "101" may correspond to the value of the first information field being 5.

It should be understood that, in the embodiments of the present application, "first" and "second" are merely used to distinguish different objects, and do not limit the scope of the embodiments of the present application.

In one embodiment, the value of the first information field may belong to a first set. When the format of the Downlink Control signaling is Downlink Control Information (DCI) format (format)1_ 0, the first set may be protocol-specified; if the format of the Downlink Control signaling is a Downlink Control Information (DCI) format (format)1_1, the first set may be configured by the network device.

In a possible embodiment, the first information field may be used to determine whether to trigger the terminal device to send the feedback information.

As an example, at least one bit of the first information field may be used to determine whether to trigger the terminal device to send the first feedback information.

Illustratively, if the bit number of the first information field is 1, the bit "1" may trigger the terminal device to send the first feedback information. At this time, in an embodiment, the physical resource for the terminal device to send the first feedback information may be preset; or, the terminal device may send the first feedback information by using the physical resource that sent the feedback information at the previous time; still alternatively, the network device may send the first configuration information to the terminal device, where the first configuration information includes a physical resource for the terminal device to send the first feedback information.

The bit "0" does not trigger the terminal device to send the first feedback information. At this time, the terminal device may send the second feedback information to the network device based on the subsequent trigger signaling.

For another example, if the number of bits of the first information field is multiple, for example, the number of bits of the first information field is 3, referring to table 1 again, if the number of bits of the first information field is "011", the terminal device may be triggered to send the first feedback information; and if the bit of the first information field is '111', not triggering the terminal equipment to send the first feedback information.

In one embodiment, the first feedback information or the second feedback information may be feedback information of downlink control signaling or feedback information of a data channel scheduled by the downlink control signaling.

It should be understood that, when the value of the first information field is the first value, in a scenario sensitive to delay or having a high requirement for delay, the feedback information of the downlink control signaling or the data channel scheduled by the downlink control signaling may be transmitted in the time unit corresponding to the first value, that is, when the first feedback information is transmitted in the time unit corresponding to the first value, the COT where the first feedback information is located may be the same as the COT where the downlink control signaling is located.

It should also be understood that, when the value of the first information field is the second value, for a scenario with low latency requirement, the feedback information of the downlink control signaling or the data channel scheduled by the downlink control signaling may not be sent immediately, but when the feedback information of the downlink control signaling or the data channel scheduled by the downlink control signaling reaches a certain number, the feedback is performed uniformly, that is, when the second information field is used to indicate the second parameter, the COT where the second feedback information is located may be different from the COT where the downlink control signaling is located, so that the flexibility of the system may be improved.

In one embodiment, in the embodiment of the present application, the method 200 may further include: and the terminal equipment determines the parameters indicated by the second information domain according to the values of the first information domain.

Specifically, when the value of the first information field is a first value, the terminal device may determine that a second information field of the second information field is used to indicate a first parameter, where the first parameter is used to transmit first feedback information in a time unit corresponding to the first value; or

When the first information field takes the value of the second value, the terminal device may determine that the second information field is used to indicate the second parameter. Wherein the second parameter is different from the first parameter.

In one embodiment, the first parameter may include, but is not limited to, at least one of: a Physical Resource parameter of a Physical Uplink Control Channel (PUCCH) carrying the first feedback information, such as a position of a Physical Resource Block (PRB); and carrying the power parameter of the PUCCH of the first feedback information.

Of course, the first parameter may also include other parameters such as Modulation and Coding Scheme (MCS) of the PUCCH carrying the first feedback information.

In one embodiment, the first parameter is used for transmitting the first feedback information in a time unit corresponding to the first value, which may be understood as: the first parameter is used for transmitting first feedback information, and the first feedback information is transmitted on a time unit corresponding to the first value. The first parameter for transmitting the first feedback information may be understood as: when the first parameter includes a physical resource parameter and/or a power parameter, the first feedback information may be transmitted using the physical resource parameter and/or the power parameter included in the first parameter.

The second parameter may include, but is not limited to: the information of the group and/or the number of transmitted downlink control signaling or data channels corresponding to the group.

The number of transmitted downlink control signaling or data channels corresponding to the above-mentioned group can be understood as follows: the number of transmitted downlink control signaling or the number of data channels in a group.

For example, in the first group, there are 5 transmitted downlink control signaling, and the number of the transmitted downlink control signaling corresponding to the first group is 5.

The group mentioned in the above may be a signaling group or a channel group where a downlink control signaling or a data channel scheduled by the downlink control signaling is located, or the group mentioned in the above may be a downlink resource group occupied by the downlink control signaling or the data channel scheduled by the downlink control signaling. That is, the group may be allocated based on the downlink control signaling or the data channel scheduled by the downlink control signaling, or the group may be allocated based on the downlink resource occupied by the downlink control signaling or the data channel scheduled by the downlink control signaling.

For example, the terminal device receives 5 downlink control signaling, which are DCI 1, DCI 2, DCI 3, DCI 4, and DCI 5, where downlink resources occupied by DCI 1, DCI 2, and DCI 4 are downlink resources 1, and downlink resources occupied by DCI 3 and DCI 5 are downlink resources 2, at this time, the 5 DCI may be divided into two groups based on the downlink resources, where DCI 1, DCI 2, and DCI 4 belong to one group, and DCI 3 and DCI 5 belong to another group.

It should be understood that the term "and/or" in the embodiments of the present application is only one kind of association relationship describing an associated object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

It should also be understood that the specific examples in the embodiments of the present application are for the purpose of promoting a better understanding of the embodiments of the invention, and are not intended to limit the scope of the embodiments of the present application.

In one embodiment, the downlink resource group may be a downlink burst (burst) or a Channel Occupancy Time (COT).

In order to facilitate an understanding of embodiments of the present application, bursts are explained below. There may be switching between uplink transmission and downlink transmission in a COT, if the uplink and downlink are not switched in a period of time unit, it is a burst; if a handover is performed, it is another burst. For example, there are 10 timeslots, timeslot 0, timeslot 1 … … timeslot 9, timeslot 0 to timeslot 3 are uplink transmissions, timeslot 4 to timeslot 7 are downlink transmissions, timeslot 8 and timeslot 9 are uplink transmissions, and there are 3 bursts at this time, timeslot 0 to timeslot 3 are one burst, timeslot 4 to timeslot 7 are one burst, and timeslot 8 and timeslot 9 are one burst.

The number of the sent downlink control signaling or data channels corresponding to the group may be: the signaling group or the channel group includes the number of transmitted downlink control signaling or data channels, or may be the number of transmitted downlink control signaling or data channels on the downlink resource group.

As an example, in this embodiment of the present application, a Downlink Assignment Index (DAI) may be used to indicate the number of transmitted Downlink control signaling or data channels corresponding to a group. The DAI may count downlink control signaling or data channels with the same group information.

For example, if the group is a signaling group, the value of the DAI is a, which may indicate that the current downlink control signaling is the a +1 th downlink control signaling sent or received in the group, or the total number of downlink control signaling in the group is a +1 up to the current downlink control signaling sending time or receiving time.

According to the technical scheme, the accuracy can be improved by indicating the number of the sent downlink control signaling or data channels corresponding to the group through the DAI. For example, if the network device sends 3 downlink control signaling belonging to the same group to the terminal device, and when the terminal device receives the 2 nd downlink control signaling, the value of the DAI is 2, the terminal device may determine that the 2 nd downlink control signaling sent by the network device is not received according to the value of the DAI, so that the accuracy may be improved.

In one embodiment, the second information field may indicate information of the group through an index or an identification of the group. For example, index 1 indicates a first group, index 2 indicates a second group, the terminal device receives downlink control signaling 1, and the second information field of the downlink control signaling 1 indicates index 1, so that the terminal device can determine that the downlink control signaling 1 belongs to the first group according to the index 1.

In an embodiment, in this embodiment of the present application, the second parameter may include a third parameter, where the third parameter may be used to associate downlink control signaling with trigger signaling, and the trigger signaling is used to trigger the second feedback information. Illustratively, the third parameter may be information of the group.

In one embodiment, the third parameter is used to associate the downlink control signaling with the trigger signaling, which can be understood as: the trigger signaling also includes a third parameter. And when the triggering signaling comprises the third parameter, indicating that the triggering signaling is used for triggering the downlink control signaling or the feedback information of the data channel scheduled by the downlink control signaling.

In a possible embodiment, when the second information field is used to indicate the second parameter, the method 200 may further include: the method comprises the steps that terminal equipment receives a trigger signaling sent by network equipment, wherein the trigger signaling indicates at least one group; and the terminal equipment responds to the trigger signaling and sends second feedback information to the network equipment, wherein the second feedback information comprises feedback information corresponding to at least one group.

The second feedback information is feedback information of the downlink control signaling or feedback information of a data channel scheduled by the downlink control signaling. The second feedback information may be carried in a PUCCH, and the PUCCH may include feedback information of a downlink control signaling or a data channel.

The feedback information corresponding to the group may be understood as: feedback information of downlink control signaling in the group or feedback information of a data channel scheduled by the downlink control signaling.

That is, if the trigger signaling received by the terminal device indicates the first group and the second group, the terminal device may send second feedback information of the downlink control signaling in the first group and the second group to the network device, or the terminal device may send second feedback information of the data channel scheduled by the downlink control signaling in the first group and the second group to the network device.

In one possible embodiment, the method 200 may further include: the terminal device determines bits of the second feedback information.

In one implementation, the terminal device may determine bits of the second feedback information based on the number of the at least one group and the number of feedback information corresponding to each group.

As an example, the terminal device may determine the number of feedback information corresponding to each group based on the number of transmitted downlink control signaling or the number of data channels corresponding to the downlink control signaling corresponding to each group. That is, the terminal device may determine the amount of the feedback information corresponding to each signaling or channel group based on the amount of the transmitted downlink control signaling or data channels included in each signaling group or channel group; alternatively, the terminal device may determine the number of feedback information corresponding to each downlink resource group based on the number of downlink control signaling or data channels that have been sent on each downlink resource group.

For example, if the network device transmits DCI 1, DCI 2, and DCI 3 on downlink resource 1, DCI 4 on downlink resource 2, and DCI 5 on downlink resource 3, the DCI 1, DCI 2, and DCI 3 belong to downlink resource group 1, DCI 4 belongs to downlink resource group 2, and DCI 5 belongs to downlink resource group 3, the terminal device may determine that the number of feedback information corresponding to downlink resource group 1 is 3, the number of feedback information corresponding to downlink resource group 2 is 1, and the number of feedback information corresponding to downlink resource group 3 is 1.

In this case, the terminal device may determine the number of feedback information corresponding to each group based on the DAI, that is, the terminal device may determine the number of feedback information in each group based on the value of the last DAI received in each group. For example, if the value of the last DAI of the first group received by the terminal device is 4, the terminal device may determine that there are 5 pieces of feedback information in the first group; if the last DAI of the second group received by the terminal device has a value of 6, the terminal device may determine that there are 7 pieces of feedback information in the second group.

As another example, the number of feedback information corresponding to each group may be a protocol specification, preset on the terminal device. In this case, the number of feedback information corresponding to each group may be constant, and the terminal device may multiply the number of feedback information corresponding to each group by the number of groups to obtain the total number of second feedback information. For example, if the number of feedback information in each group is 5, and there are 3 groups in total, the total number of the second feedback information is 15. If each feedback information occupies 1 bit, the bit of the second feedback information is 15.

As another example, the amount of feedback information for each group may be network device configured. At this time, the network device may transmit second configuration information including the number of feedback information corresponding to each group to the terminal device, and the terminal device may determine the number of feedback information corresponding to each group based on the second configuration information.

In one embodiment, the network device may configure the number of feedback information corresponding to each group periodically, for example, configure the number of feedback information corresponding to each group every 5 ms. It should be understood that the number of feedback information corresponding to each group configured by the network device at a time may be the same or different. For example, the number of feedback information in the first group configured by the network device at the previous time is 5, and the number of feedback information in the first group configured by the network device at the current time may also be 5, or may be 3.

In one embodiment, the network device may configure the number of feedback information corresponding to each group once every 10 downlink control signaling transmissions.

In one embodiment, the network device may also configure the number of feedback information corresponding to each group only once.

The following describes the technical solution of the embodiment of the present application in detail with reference to table 2 and fig. 3, and table 3 and fig. 4.

As can be seen from table 2 and fig. 3, the network device sends 10 pieces of DCI to the terminal device, where there are 1 pieces of DCI having the first information field with the first value and 9 pieces of DCI having the second value in the 10 pieces of DCI. When the value of the first information domain is a first value, the second information domain indicates physical resources of a PUCCH bearing the first feedback information; and when the value of the first information field is a second value, the second information field indicates the information of the group.

As can also be seen from fig. 3, the DCI with the second value is further divided into 3 groups, the DCI with the group number 000 belongs to the first group, and there are 3 DCIs in the first group; the DCI with group number 001 belongs to the second group, and there are 4 DCIs in the second group; DCI with group number 010 belongs to the third group, and there are 2 DCIs within the third group.

The network device sends a trigger signaling to the terminal device in COT n +1, where the trigger signaling indicates the first group and the second group. And after receiving the trigger signaling, the terminal equipment sends second feedback information of the DCI in the first group and the second group to the network equipment in the PUCCH corresponding to the trigger signaling.

Further, the terminal device may determine the total number of bits of the second feedback information carried in the PUCCH. If the number of feedback information in the first group is 3 and the number of feedback information in the second group is 4, the number of second feedback information is 7. If each piece of feedback information is 1 bit, the total number of bits of the second feedback information carried in the PUCCH is 7.

TABLE 3

As can be seen from table 3 and fig. 4, the network device sends 10 pieces of DCI to the terminal device, where there are 1 pieces of DCI having the first information field with the first value and 9 pieces of DCI having the second value in the 10 pieces of DCI. When the value of the first information field is a first value, the second information field indicates physical resources of a PUCCH bearing the first feedback information and indicates power parameters of the PUCCH bearing the first feedback information; and when the value of the first information field is a second value, the second information field indicates the information and the DAI of the group.

In fig. 4, "yy" represents information of a group and "xxx" represents DAI when the second information field indicates information of a group and DAI. As can also be seen from fig. 4, the DCI with the second value is further divided into 2 groups, the DCI with group number 00 belongs to the first group, and there are 8 DCIs in the first group; DCI with group number 01 belongs to the second group, and there are 1 DCI in the second group.

Further, the terminal device may determine the total number of bits of the second feedback information carried in the PUCCH. Specifically, the terminal device may determine the total number of bits of the second feedback information carried in the PUCCH based on the DAI. If the value of the last DAI received by the terminal device in the first group is 7, the terminal device may determine that the number of feedback information in the first group is 8; if the terminal device receives the last DAI in the second group, the value of the last DAI is 0, the terminal device may determine that the number of feedback information in the second group is 1, and the terminal device may determine that the number of second feedback information is 9. If each piece of feedback information is 1 bit, the total number of bits of the second feedback information carried in the PUCCH is 7.

In the embodiment of the application, the downlink control signaling transmitted between the network device and the terminal device includes the first information domain and the second information domain, when the value of the first information domain is the first value, the second information domain is used for indicating the first parameter, the first parameter is used for transmitting the first feedback information on the time unit corresponding to the first value, and when the value of the first information domain is the second value, the second information domain is used for indicating the second parameter of the first parameter, thereby realizing that different values of the first information domain can indicate different functions of the domain of the second information, and improving the flexibility of the downlink control signaling.
