It should be understood that FIG. 1 only shows a communication system composed of one terminal device and one network device. In fact, the embodiments of the present application can also be applied to a communication system composed of multiple terminal devices and network devices, wherein each Terminal devices can transmit their respective UCIs to network devices as needed.

In the existing LTE system, the terminal device is only configured with authorized time-frequency resources, and the terminal device needs to send UCI to the network device through the authorized time-frequency resource, that is to say, the terminal device can only use a relatively single time-frequency resource to transmit UCI to the network device.

FIG. 2 is a schematic flowchart of a method for transmitting uplink control information according to an embodiment of the present application. The method of FIG. 2 may be performed by a terminal device. The method 200 of FIG. 2 includes:

210. The terminal device determines a target channel from multiple channels, where the multiple channels include a Grant Free Physical Uplink Shared Channel (Grant Free Physical Uplink Shared Channel, GF-PUSCH) and a GB-PUSCH.

Optionally, the terminal device can arbitrarily select a channel from GF-PUSCH and GB-PUSCH as the target channel.

Optionally, the terminal device may also select the target channel from the multiple channels according to the instruction of the network device.

Specifically, the terminal device receives the first indication information sent by the network device, and the terminal device determines the target channel from the multiple channels includes: the terminal device selects GF-PUSCH or GB-PUSCH from the multiple channels according to the first indication information as the target channel. . The first indication information is used to instruct the terminal device to preferentially select GF-PUSCH or GB-PUSCH as the target channel from multiple channels.

It should be understood that in addition to GB-PUSCH and GF-PUSCH, the above-mentioned multiple channels may also include a Physical Uplink Control Channel (PUCCH), that is, the terminal device can select a data channel as a target channel in addition to In addition, the control channel can also be selected as the target channel.

220. The terminal device sends the UCI to the network device through the target channel.

In this application, the terminal device can flexibly select a target channel from multiple channels to send UCI when GF-PUSCH and GF-PUSCH are configured, which is different from the prior art solution that can only rely on GB-PUSCH and PUCCH to send UCI Compared with the UCI method, the resource for transmitting the UCI can be selected more flexibly.

It should be understood that the above-mentioned first indication information is to instruct the terminal equipment to select GF-PUSCH or GB-PUSCH from multiple channels as the target channel (that is to say, the first indication information indicates that the terminal equipment selects GF-PUSCH or GB-PUSCH from multiple channels and GB-PUSCH to select the target channel), and further indicate whether the terminal device preferentially selects GF-PUSCH or GB-PUSCH as the target channel (equivalent to indicating the priorities of GB-PUSCH and GF-PUSCH).

Optionally, the above-mentioned first indication information may be borne in the RRC signaling or DCI sent by the network device to the terminal device. Therefore, a new signal may be added to the RRC signaling and downlink control information (downlink control information, DCI). field to represent the first indication information.

The above-mentioned first indication information can either instruct the terminal device to preferentially select GF-PUSCH from multiple channels as the target channel (equivalent to GF-PUSCH having a higher priority than GB-PUSCH), or instruct the terminal device to preferentially select GF-PUSCH from multiple channels. Select GB-PUSCH as the target channel (equivalent to GB-PUSCH having a higher priority than GF-PUSCH). The two situations will be described in detail below with reference to Example 1 and Example 2, respectively.

Example 1: GF-PUSCH has higher priority than GB-PUSCH

In example 1, when the priority of GF-PUSCH is higher than that of GB-PUSCH, according to the relationship between the transmission of UCI by the terminal equipment and the transmission of uplink data by the terminal equipment, the method for the terminal equipment to determine the target channel from multiple channels can be divided into two kind.

Method 1: When UCI is transmitted on the data channel, it must be transmitted together with the uplink data

In mode 1, the terminal device selects the target channel according to the first indication information and whether the terminal device sends uplink data.

Specifically, the terminal device selects GF-PUSCH or GB-PUSCH from multiple channels as the target channel according to the first indication information, including: the terminal device determines whether to send uplink data on the GF-PUSCH; if the uplink data is sent on the GF-PUSCH, The terminal device selects GF-PUSCH as the target channel; if the uplink data is not sent on the GF-PUSCH, the terminal device determines whether to send the uplink data on the GB-PUSCH; if the uplink data is sent on the GB-PUSCH, the terminal device selects the GB-PUSCH as the target channel. .

It should be understood that, in the first manner, if the terminal device neither sends uplink data on GB-PUSCH nor sends uplink data on GF-PUSCH, then the terminal device sends UCI on the uplink control channel PUCCH.

In mode 1, when UCI is transmitted on the data channel, the UCI must be transmitted with the uplink data, otherwise the UCI can only be transmitted on the PUCCH. Therefore, when the terminal device neither transmits uplink data on GF-PUSCH nor transmits uplink data on GB-PUSCH, the terminal device selects PUCCH as the target channel.

The following describes in detail how the terminal device sends the UCI to the network device in the first mode with reference to FIG. 3 .

As shown in Figure 3, the specific process for the terminal device to send the UCI to the network device is as follows:

310. The terminal device needs to send the UCI to the network device in the current time slot;

320. The terminal device determines whether there is uplink data that needs to be sent in the current time slot;

330. If there is uplink data that needs to be sent in the current time slot, the terminal device determines whether there is GF-PUSCH data;

340. If there is GF-PUSCH data, the terminal device sends UCI on GF-PUSCH;

350. If there is no GF-PUSCH data, the terminal device sends UCI on GB-PUSCH;

360. If there is no uplink data in the current time slot, the terminal device sends the UCI on the PUCCH.

It should be understood that determining whether there is GF-PUSCH data in step 330 by the terminal device is equivalent to the situation where uplink data needs to be sent in the current time slot, and the terminal device then determines whether the uplink data is sent on the GF-PUSCH, where the GF-PUSCH data Refers to the uplink data that needs to be sent on the GF-PUSCH.

Taking the specific flow shown in FIG. 3 above as an example, when the above-mentioned first indication information is carried in RRC signaling, the specific format of the RRC signaling is as follows:

Among them, PUCCH-ConfigDedicated is a PUCCH configuration message dedicated to terminal equipment. It contains multiple fields. The meaning of each field is as follows: The value of the simultaneousPUCCH-PUSCH field is false, indicating that the terminal equipment cannot transmit PUCCH and PUSCH at the same time. Therefore, the terminal equipment Only all UCIs can be transmitted on PUSCH; UCIonPUSCH is a field related to the data channel, and the value of its subfield PriorityOnPUSCHwithGrant is true, indicating that the terminal device preferentially selects GB-PUSCH when selecting the target channel.

It should be understood that, in the above RRC signaling, a field may also be set to indicate that when the UCI is transmitted on the data channel, it must be transmitted together with the uplink data.

Optionally, in mode 1, the terminal device can either send all the UCIs to be transmitted to the network device on the data channel (GF-PUSCH or GB-PUSCH), or can only send all the UCIs to be transmitted to the network device. part of the UCI, the remaining part of the UCI can be transmitted on the PUCCH.

Specifically, as shown in FIG. 4 , the specific process for the terminal device to send the UCI to the network device is as follows:

410. The terminal device needs to send the UCI to the network device in the current time slot;

420. The terminal device determines whether there is uplink data that needs to be sent in the current time slot;

430. If there is uplink data that needs to be sent in the current time slot, the terminal device determines whether there is GF-PUSCH data;

440. If there is GF-PUSCH data, the terminal device sends all or part of the UCI on the GF-PUSCH;

450. If there is no GF-PUSCH data, the terminal device sends all or part of the UCI on the GB-PUSCH;

460. If there is no uplink data in the current time slot, the terminal device sends all UCIs on the PUCCH.

It should be understood that, in step 450 and step 460, the total UCI refers to the total UCI that the terminal device will currently transmit to the network device.

Taking the above process shown in FIG. 4 as an example, when the above-mentioned first indication information is carried in RRC signaling, the specific format of the RRC signaling is as follows:

Among them, PUCCH-ConfigDedicated is a PUCCH configuration message dedicated to terminal equipment. It contains multiple fields. The meaning of each field is as follows: The value of the simultaneousPUCCH-PUSCH field is true, indicating that the terminal equipment can transmit PUCCH and PUSCH at the same time. Therefore, the terminal equipment Part of UCI can be transmitted on PUSCH, and another part of UCI can be transmitted on PUCCH; UCIonPUSCH is a field related to the data channel, and the value of its subfield PriorityOnPUSCHwithGrant is false, indicating that the terminal device will not give priority to GB- PUSCH, that is, GF-PUSCH is preferentially selected.

It should be understood that, in the above RRC signaling, a field may also be set to indicate that when the UCI is transmitted on the data channel, it must be transmitted together with the uplink data.

Method 2: UCI can be transmitted separately on the data channel

In the second mode, the terminal device does not need to judge whether there is uplink data on the GF-PUSCH, but directly uses the GF-PUSCH as the target channel, and transmits the UCI through the GF-PUSCH.

Specifically, the terminal device selects GF-PUSCH or GB-PUSCH from multiple channels as the target channel according to the first indication information, which specifically includes: the terminal device selects the GF-PUSCH as the target channel.

It should be understood that in the second mode, after the terminal selects the GF-PUSCH as the target channel, when subsequently transmitting the UCI on the GF-PUSCH, the UCI can be transmitted separately on the GF-PUSCH, or the UCI can be simultaneously transmitted on the GF-PUSCH. and upstream data.

Example 2: GB-PUSCH has higher priority than GF-PUSCH

Similar to Example 1, in Example 2, when the priority of GB-PUSCH is higher than that of GF-PUSCH, according to the relationship between the transmission of UCI by the terminal device and the transmission of uplink data by the terminal device, the terminal device can determine the target channel from multiple channels. There are two ways.

Mode 3: When UCI is transmitted on the data channel, it must be transmitted together with the uplink data.

In the third mode, the terminal device selects the target channel according to the first indication information and whether the terminal device sends uplink data.

Specifically, the terminal device selects GF-PUSCH or GB-PUSCH from multiple channels as the target channel according to the first indication information, which specifically includes: the terminal device determines whether to send uplink data on GB-PUSCH; For uplink data, the terminal device selects GB-PUSCH as the target channel; if the uplink data is not sent on GB-PUSCH, the terminal device determines whether to send uplink data on GF-PUSCH; if uplink data is sent on GF-PUSCH, the terminal device selects GF-PUSCH as the target channel.

In mode 3, when UCI is transmitted on the data channel, the UCI must be transmitted with the uplink data, otherwise the UCI can only be transmitted on the PUCCH. Therefore, when the terminal device neither transmits uplink data on GB-PUSCH nor transmits uplink data on GF-PUSCH, the terminal device selects PUCCH as the target channel.

The following describes in detail how the terminal device sends the UCI to the network device in the third mode with reference to FIG. 5 .

As shown in Figure 5, the specific process for the terminal device to send the UCI to the network device is as follows:

510. The terminal device needs to send the UCI to the network device in the current time slot;

520. The terminal device determines whether there is uplink data that needs to be sent in the current time slot;

530. If there is uplink data that needs to be sent in the current time slot, the terminal device determines whether there is GB-PUSCH data;

540. If there is GB-PUSCH data, the terminal device sends UCI on GB-PUSCH;

550. If there is no GB-PUSCH data, the terminal device sends UCI on GF-PUSCH;

560. If there is no uplink data in the current time slot, the terminal device sends the UCI on the PUCCH.

It should be understood that, in step 530, the terminal device determines whether there is GB-PUSCH data, which is equivalent to the situation that the uplink data needs to be sent in the current time slot, and the terminal device then determines whether the uplink data is sent on the GB-PUSCH. Here, the GB-PUSCH PUSCH data refers to uplink data that needs to be sent on GB-PUSCH.

In addition, in the third mode, the terminal device can either send all the UCI to be transmitted to the network device on the data channel (GF-PUSCH or GB-PUSCH), or can only send a part of all the UCI to be transmitted to the network device UCI, the remaining part of UCI can be transmitted on PUCCH.

Specifically, as shown in FIG. 6 , the specific process for the terminal device to send the UCI to the network device is as follows:

610. The terminal device needs to send the UCI to the network device in the current time slot;

620. The terminal device determines whether there is uplink data that needs to be sent in the current time slot;

630. If there is uplink data that needs to be sent in the current time slot, the terminal device determines whether there is GB-PUSCH data;

640. If there is GB-PUSCH data, the terminal device sends all or part of UCI on GB-PUSCH;

650. If there is no GB-PUSCH data, the terminal device sends all or part of the UCI on the GF-PUSCH;

660. If there is no uplink data in the current time slot, the terminal device sends all or part of the UCI on the PUCCH;

Mode 4: UCI can be transmitted separately on the data channel

In the fourth mode, the terminal device does not need to judge whether there is uplink data on the GB-PUSCH, but directly uses the GB-PUSCH as the target channel, and transmits the UCI through the GB-PUSCH.

Specifically, the terminal device selects GF-PUSCH or GB-PUSCH from multiple channels as the target channel according to the first indication information, which specifically includes: the terminal device selects the GB-PUSCH as the target channel.

It should be understood that in Mode 4, after the terminal selects GB-PUSCH as the target channel, when UCI is subsequently transmitted on GB-PUSCH, UCI can be transmitted separately on GB-PUSCH, or UCI can be transmitted simultaneously on GB-PUSCH. and upstream data.

It should be understood that it is described above that the terminal device can determine the target channel according to the priority information indicated by the first indication information. In fact, the terminal device can also use other methods to determine the target channel. For example, the terminal device directly The type of UCI to determine the target channel.

Optionally, as an embodiment, in the above step 210, the terminal device determining the target channel from the multiple channels specifically includes: the terminal device selects GF-PUSCH or GB-PUSCH as the target channel according to the type of UCI.

The terminal device can select a data channel matching the type of UCI according to the type of UCI, which can improve the effect of sending UCI.

Optionally, when the terminal equipment selects GF-PUSCH or GB-PUSCH as the target channel according to the type of UCI, according to the relationship between the transmission of UCI by the terminal equipment and the transmission of uplink data by the terminal equipment, the terminal equipment can select the GF according to the type of UCI. -PUSCH or GB-PUSCH as the target channel is divided into two cases, and the two cases are described in detail below with reference to Example 3 and Example 4.

Example 3: UCI can be transmitted alone on the data channel

It should be understood that in Example 3, the UCI does not have to be sent together with the uplink data. Therefore, after the terminal device determines the type of UCI, it can directly select the physical uplink data channel corresponding to the type of UCI as the target channel.

Optionally, the terminal device determines the target channel from multiple channels, including: when the type of UCI belongs to the first type, the terminal device selects GF-PUSCH as the target channel; when the type of UCI belongs to the second type In this case, the terminal device selects GB-PUSCH as the target channel; wherein the first type and the second type are different.

Specifically, as shown in Figure 7, the terminal device selects the target channel according to the type of UCI, and the specific process of sending the UCI on the target channel includes:

710. The terminal device needs to send the UCI to the network device in the current time slot;

720. The terminal device determines the type of UCI;

730. In the case that the type of the UCI belongs to the first type, send the UCI on the GF-PUSCH;

740. In the case that the type of the UCI belongs to the second type, send the UCI on the GB-PUSCH.

Example 4: When UCI is transmitted on the data channel, it must be transmitted together with the uplink data

It should be understood that in Example 4, if the UCI is transmitted on the data channel, it must be transmitted together with the uplink data, that is, after the data channel corresponding to the UCI is determined according to the type of the UCI, the data corresponding to the UCI needs to be judged again. Whether there is uplink data that needs to be sent on the channel, if there is no uplink data that needs to be sent, then the UCI can be transmitted on the PUCCH.

Optionally, the terminal device determines the target channel from multiple channels, which specifically includes: in the case that the type of UCI belongs to the first type, the terminal device determines whether to send uplink data on the GF-PUSCH; if the uplink data is sent on the GF-PUSCH. , the terminal device selects the GF-PUSCH as the target channel; and when the type of UCI belongs to the second type, the terminal device determines whether to send the uplink data on the GB-PUSCH; if the uplink data is sent on the GB-PUSCH , the terminal device selects GB-PUSCH as the target channel.

Specifically, as shown in Figure 8, the terminal device selects the target channel according to the type of UCI, and the specific process of sending the UCI on the target channel includes:

810. The terminal device needs to send the UCI to the network device in the current time slot;

820. The terminal device determines the type of UCI;

830. In the case that the type of UCI belongs to the first type, the terminal device determines whether to send uplink data on the GF-PUSCH;

840. When the terminal device determines to send the uplink data on the GF-PUSCH, the terminal device sends the UCI on the GF-PUSCH;

850. When the terminal device determines not to send uplink data on the GF-PUSCH, the terminal device sends the UCI on the PUCCH;

860. In the case that the type of UCI belongs to the second type, the terminal device determines whether to send uplink data on the GB-PUSCH;

870. When the terminal device determines to send the uplink data on the GB-PUSCH, the terminal device sends the UC on the GB-PUSCH;

880. When the terminal device determines not to send uplink data on the GB-PUSCH, the terminal device sends the UCI on the PUCCH.

Optionally, in Example 3 and Example 4, the UCI of the first type includes UCI that needs to be sent periodically, and the UCI of the second type includes UCI that does not need to be sent periodically.

Specifically, the above-mentioned first type of UCI includes periodic channel state information CSI, and the second type of UCI includes at least one of aperiodic channel state information (Channel State Information, CSI), ACK, and NACK information.

Periodic information is similar to the configuration of unlicensed resources and is suitable for transmission on GF-PUSCH, while aperiodic information, such as ACK/NACK, generally corresponds to dynamic scheduling and is suitable for transmission on GB-PUSCH.

Optionally, as an embodiment, when the terminal device is configured with multiple GF-PUSCHs, the above method 200 further includes: the terminal device receives second indication information sent by the network device, where the second indication information is used to indicate multiple GF-PUSCHs The target GF-PUSCH in the PUSCH that can be used by the terminal device to send the UCI to the network device.

It should be understood that the second indication information may be carried in the RRC signaling or DCI sent by the network device to the terminal device. Therefore, the second indication information may be represented by adding a new field to the RRC signaling and DCI.

It should be understood that when the terminal device is configured with multiple GF-PUSCHs, the target GF-PUSCH used for UCI transmission can be determined from the multiple GF-PUSCHs according to the instructions of the network device, or the terminal device itself can determine multiple GF-PUSCHs. The target GF-PUSCH is determined in the GF-PUSCH.

In addition, when the terminal device is configured with multiple GF-PUSCHs, the terminal device may indicate whether a certain GF-PUSCH sends UCI by adding different sequences to the GF-PUSCH data. Specifically, as shown in FIG. 9 , when the GF-PUSCH data transmitted by the terminal device includes the first sequence, it means that the GF-PUSCH data includes both uplink data and UCI; and when the GF-PUSCH data transmitted by the terminal device includes the first sequence In the case of two sequences, it means that the GF-PUSCH data only includes uplink data, but does not include UCI. In addition, in FIG. 9, when UCI and uplink data are transmitted together, UCI and uplink data occupy different time domain resources. Actually, as shown in FIG. 10 , when UCI and uplink data are transmitted together, UCI and uplink data can also occupy different frequency domain resources. That is to say, when UCI is transmitted through the GF-PUSCH channel, UCI and uplink data may be time-division multiplexed or frequency-division multiplexed. It should be understood that either time division multiplexing or frequency division multiplexing may be used between the first sequence and the second sequence and the uplink data.

The first sequence and the second sequence may be different reference signal (Reference Signal, RS) sequences. For example, the first sequence may be RS1, and the second sequence may be RS2. After receiving the GF-PUSCH data, the network device passes Detect the RS sequence to determine whether the GF-PUSCH data contains UCI. If the network device detects RS1 in the received GF-PUSCH data, then the network device determines that the GF-PUSCH contains UCI (at this time, the GF-PUSCH data contains Uplink data and UCI); and if the network device detects RS2 in the received GF-PUSCH data, the network device determines that the GF-PUSCH does not contain UCI (at this time, the GF-PUSCH data only contains uplink data).

When there is a terminal device configured with multiple GF-PUSCHs, the terminal device can add different sequences to the GF-PUSCH data, so that the network device can identify whether the GF-PUSCH channel contains UCI, so that the network device can identify the GF-PUSCH on the GF-PUSCH. The transmitted data is properly parsed.

Optionally, when the terminal device sends UCI on GF-PUSCH, it can only send uplink data on GF-PUSCH, or it can send both uplink data and UCI on GF-PUSCH. The device may also instruct the GF-PUSCH channel to send only UCI or both UCI and uplink data by sending different demodulation reference signals (Demodulation Reference Signal, DMRS) to the network device.

Specifically, when the terminal device sends DMRS1 to the network device, it means that the GF-PUSCH data only contains UCI without uplink data; and when the terminal device sends DMRS2 to the network device, it means that the GF-PUSCH data contains both UCI. Also includes upstream data.

According to the detected DMRS, the network device can determine that the terminal device sends UCI, so as to avoid errors when the network device recognizes the GF-PUSCH data.

The method for transmitting UCI in this embodiment of the present application is described in detail above from the perspective of terminal equipment with reference to FIG. 2 to FIG. 10 . The method for transmitting UCI in this embodiment of the present application is described below in conjunction with FIG. 11 from the perspective of network equipment. It should be understood that the method for transmitting UCI in this embodiment of the present application described below from the perspective of a network device corresponds to the method for transmitting UCI in this embodiment of the present application described above from the perspective of a terminal device. For the sake of brevity, it is appropriately omitted below. Duplicate description.

FIG. 11 is a schematic flowchart of a method for transmitting uplink control information according to an embodiment of the present application. The method of FIG. 11 may be performed by a network device. The method 1100 of FIG. 11 includes:

1110. The network device determines a target channel from multiple channels, where the multiple channels include an unlicensed physical uplink shared channel GF-PUSCH and a licensed physical uplink shared channel GB-PUSCH.

It should be understood that in step 1110, the terminal device may determine the target channel from the multiple channels in the same manner as the terminal device. Specifically, the terminal device can arbitrarily select a channel from GF-PUSCH and GB-PUSCH as the target channel, and send indication information to the network device, where the indication information is used to instruct the terminal device which channel to select as the target channel. After the device receives the indication information, it can determine the target channel according to the indication information, so that the target channel determined by the network device is consistent with the target channel determined by the terminal device.

In addition, the network device and the terminal device can also determine the target channel from the multiple channels according to the pre-agreed rules and methods (specifically, the rules or methods specified in the communication standard or protocol).

Optionally, the network device may determine the target channel from GF-PUSCH and GB-PUSCH according to the priorities of GF-PUSCH and GB-PUSCH (the priorities of GF-PUSCH and GB-PUSCH may be predetermined).

In addition, the network device may also send first indication information to the terminal device, where the first indication information is used to instruct the terminal device to preferentially select GF-PUSCH or GB-PUSCH as a target channel from multiple channels. In this way, after receiving the first indication information, the terminal device can preferentially select GF-PUSCH or GB-PUSCH from multiple channels as the target channel according to the priorities of GF-PUSCH and GB-PUSCH.

Optionally, before the network device receives the UCI sent by the terminal device from the target channel, the above method 1100 further includes: the network device sends first indication information to the terminal device, where the first indication information is used to instruct the terminal device to select from multiple channels. GF-PUSCH or GB-PUSCH is preferentially selected as the target channel.

Optionally, the above-mentioned first indication information may be carried in RRC signaling or DCI sent by the network device to the terminal device. Therefore, a new field may be added to the RRC signaling and DCI to represent the first indication information.

It should be understood that in addition to GB-PUSCH and GF-PUSCH, the above-mentioned multiple channels may also include PUCCH, that is to say, in addition to selecting the data channel as the target channel, the terminal device may also select the control channel as the target channel .

1120. The network device receives the UCI sent by the terminal device from the target channel.

In this application, the network device can flexibly select a target channel from multiple channels to transmit UCI when GF-PUSCH and GF-PUSCH are configured, which is different from the prior art solution that can only rely on GB-PUSCH and PUCCH to transmit Compared with the UCI method, the resource for transmitting the UCI can be selected more flexibly.

Optionally, as an embodiment, when the first indication information is specifically used to instruct the terminal device to preferentially select GF-PUSCH from multiple channels as the target channel, the network device determines the target channel from the multiple channels, including: the network device Determine whether there is uplink data transmitted on GF-PUSCH; if there is uplink data transmitted on GF-PUSCH, the network device selects GF-PUSCH as the target channel; if no uplink data is transmitted on GF-PUSCH, the network device determines whether there is uplink data. The data is transmitted on the GB-PUSCH; if there is uplink data transmitted on the GB-PUSCH, the network device selects the GB-PUSCH as the target channel. It should be understood that in this case, when the UCI is transmitted on the data channel, it must be transmitted together with the uplink data.

Specifically, when the priority of the GF-PUSCH is higher, the terminal device also determines the target channel according to whether there is uplink data on the GF-PUSCH. This way of determining the target channel is similar to the way in which the terminal device determines the target channel in the first way in the above example 1. It will not be described in detail here.

Data is transmitted on GF-PUSCH; if there is uplink data transmitted on GF-PUSCH, the network device selects GF-PUSCH as the target channel. It should be understood that in this case, when the UCI is transmitted on the data channel, it must be transmitted together with the uplink data.

Specifically, when the priority of the GB-PUSCH is higher, the terminal device also determines the target channel according to whether there is uplink data on the GB-PUSCH. This manner of determining the target channel is similar to the manner in which the terminal device determines the target channel in the third manner of the second example above. It will not be described in detail here.

Optionally, when the UCI can be transmitted separately on the data channel, the network device can directly determine the target channel according to the priority information of the GF-PUSCH and the GB-PUSCH.

Specifically, when the UCI can be transmitted separately on the data channel, if the first indication information is used to instruct the terminal device to preferentially select GF-PUSCH from multiple channels as the target channel, then the network device determines the target channel from the multiple channels , including: the network device selects GF-PUSCH as the target channel. In this case, the manner in which the network device determines the target channel is similar to the manner in which the terminal device determines the target channel in the second manner of the first example above. It will not be described in detail here.

However, if the first indication information is specifically used to instruct the terminal device to preferentially select GB-PUSCH from multiple channels as the target channel, then the network device determines the target channel from the multiple channels, including: the network device selects GB-PUSCH as the target channel . In this case, the manner in which the network device determines the target channel is similar to the manner in which the terminal device determines the target channel in the fourth manner in the second example above. It will not be described in detail here.

Optionally, in addition to determining the target channel according to the priority information, the network device may also directly determine the target channel according to the content of the UCI. It should be understood that both the network device and the terminal device may be predetermined to determine the target channel according to the content of the UCI.

It should be understood that at this time, the network device does not consider whether there is uplink data when determining the target channel, but directly determines the target channel according to the type of UCI. In this case, the network device determines the target channel and the terminal device in the third example above. The target channel works in a similar way. It will not be described in detail here.

Optionally, the network device determines the target channel from multiple channels, including: when the type of UCI belongs to the first type, the network device determines whether there is uplink data to be transmitted on the GF-PUSCH; if there is uplink data on the GF-PUSCH For transmission on PUSCH, the network device selects GF-PUSCH as the target channel; when the type of UCI belongs to the second type, the network device determines whether there is uplink data to be transmitted on GB-PUSCH; if there is uplink data to be transmitted on GB-PUSCH , the network device selects GB-PUSCH as the target channel; wherein, the first type and the second type are different. It should be understood that at this time, the network device needs to consider whether there is uplink data when determining the target channel. At this time, the network device determines the target channel according to the type of UCI and whether there is uplink data. In this case, the network device determines the target channel and the target channel. The manner in which the terminal device determines the target channel in Example 4 above is similar. It will not be described in detail here.

Optionally, the UCI of the first type includes UCI that needs to be sent periodically, and the UCI of the second type includes UCI that does not need to be sent periodically.

Specifically, the above-mentioned first type of UCI includes periodic channel state information CSI, and the second type of UCI includes at least one of aperiodic channel state information (Channel State Information, CSI), ACK, and NACK information.

Periodic information is similar to the configuration of unlicensed resources and is suitable for transmission on GF-PUSCH, while aperiodic information, such as ACK/NACK, generally corresponds to dynamic scheduling and is suitable for transmission on GB-PUSCH.

Optionally, as an embodiment, when the terminal device is configured with multiple GF-PUSCHs, the above method 1100 further includes: the network device sends second indication information to the terminal device, where the second indication information is used to indicate that among the multiple GF-PUSCHs The target GF-PUSCH that can be used by the terminal device to send UCI to the network device.

It should be understood that the second indication information may be carried in the RRC signaling or DCI sent by the network device to the terminal device. Therefore, the second indication information may be represented by adding a new field to the RRC signaling and DCI.
