The method for transmitting uplink control information in the embodiment of the present application is described in detail below with reference to FIG. 2 .

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 Figure 2 can be performed by a terminal device. The method 200 of Figure 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 (GF-PUSCH) and a GB-PUSCH.

Alternatively, the terminal device may arbitrarily select one channel from the GF-PUSCH and the GB-PUSCH as the target channel.

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

Specifically, the terminal device receives the first indication information sent by the network device, and the determining, by the terminal device, the target channel from the multiple channels, the terminal device: selecting, by using the first indication information, the GF-PUSCH or the GB-PUSCH as the target channel from the multiple channels. . The first indication information is used to indicate that the terminal device preferentially selects the GF-PUSCH or the GB-PUSCH as the target channel from the multiple channels.

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

It should be understood that the foregoing first indication information is to instruct the terminal device to select the GF-PUSCH or the GB-PUSCH from the plurality of channels as the target channel (that is, the first indication information indicates that the terminal device is from the GF-PUSCH in the multiple channels. And the target channel is selected in the GB-PUSCH, and further indicates whether the terminal device preferentially selects the GF-PUSCH or preferentially selects the GB-PUSCH as the target channel (equivalent to indicating the priority of the GB-PUSCH and the GF-PUSCH).

Optionally, the foregoing first indication information may be carried in RRC signaling or DCI sent by the network device to the terminal device. Therefore, a new one may be added in the RRC signaling and the downlink control information (DCI). A field indicates the first indication information.

The foregoing first indication information may indicate that the terminal device preferentially selects the GF-PUSCH as the target channel from multiple channels (equivalent to the priority of the GF-PUSCH is higher than the GB-PUSCH), and may also indicate that the terminal device takes priority from multiple channels. The GB-PUSCH is selected as the target channel (corresponding to the priority of GB-PUSCH is higher than GF-PUSCH). The two cases will be described in detail below with reference to the first embodiment and the second embodiment.

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

In the first example, when the priority of the GF-PUSCH is higher than that of the GB-PUSCH, the manner in which the terminal device determines the target channel from the multiple channels may be divided into two according to the relationship between the UCI transmitted by the terminal device and the uplink data transmitted by the terminal device. Kind.

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

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

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

It should be understood that, in the first method, if the terminal device does not send uplink data on the GB-PUSCH nor uplink data on the GF-PUSCH, the terminal device transmits the UCI on the uplink control channel PUCCH.

In mode 1, when UCI is transmitted on the data channel, UCI must be transmitted with the uplink data, otherwise UCI can only be transmitted on the PUCCH. Therefore, when the terminal device does not transmit uplink data on the GF-PUSCH or uplink data on the GB-PUSCH, the terminal device selects the PUCCH as the target channel.

A detailed description of how the terminal device sends the UCI to the network device in the first mode will be described in detail below with reference to FIG.

As shown in FIG. 3, the specific process of the terminal device transmitting the UCI to the network device is as follows:

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

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

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

340. If GF-PUSCH data exists, the terminal device sends the UCI on the GF-PUSCH.

350. If the GF-PUSCH data does not exist, the terminal device sends the UCI on the 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, in step 330, the terminal device determines whether the GF-PUSCH data exists. In the case that the current time slot needs to send the uplink data, the terminal device determines whether the uplink data is sent on the GF-PUSCH, where the GF-PUSCH data is used. It refers to the uplink data that needs to be sent on the GF-PUSCH.

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

The PUCCH-ConfigDedicated is a terminal device-specific PUCCH configuration message, which includes multiple fields, and the meaning of each field is as follows: The value of the simultaneous PUCCH-PUSCH field is false, indicating that the terminal device cannot simultaneously transmit the PUCCH and the PUSCH, and therefore, the terminal device The UCI can only be transmitted on the PUSCH; the UCIonPUSCH is a field related to the data channel, and the value of the sub-field PriorityOnPUSCHwithGrant is true, indicating that the terminal device preferentially selects the GB-PUSCH when selecting the target channel.

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

Optionally, in the first mode, the terminal device may send all the UCIs to be transmitted to the network device on the data channel (GF-PUSCH or GB-PUSCH), or may 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 of the terminal device transmitting 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 uplink data needs to be sent in the current time slot.

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

440. If GF-PUSCH data exists, the terminal device sends all UCI or partial UCI on the GF-PUSCH.

450, if there is no GF-PUSCH data, then the terminal device sends all UCI or part of 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 steps 450 and 460, all UCI refers to all UCIs that the terminal device is currently transmitting to the network device.

For example, when the first indication information is carried in the RRC signaling, the specific format of the RRC signaling is as follows:

The PUCCH-ConfigDedicated is a terminal device-specific PUCCH configuration message, which includes multiple fields, and the meaning of each field is as follows: The value of the simultaneous PUCCH-PUSCH field is true, indicating that the terminal device can simultaneously transmit the PUCCH and the PUSCH, and therefore, the terminal device A part of the UCI may be transmitted on the PUSCH, and another part of the UCI may be transmitted on the PUCCH; the UCIonPUSCH is a field related to the data channel, and the value of the subfield PriorityOnPUSCHwithGrant is false, indicating that the terminal device does not preferentially select GB when selecting the target channel. PUSCH, that is, GF-PUSCH is preferred.

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

In the second mode, the terminal device does not need to determine 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 the GF-PUSCH or the GB-PUSCH as the target channel from the multiple channels according to the first indication information, and 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, the UCI may be separately transmitted on the GF-PUSCH when the UCI is transmitted on the GF-PUSCH, or the UCI may be simultaneously transmitted on the GF-PUSCH. And upstream data.

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

Similar to the first example, in the second embodiment, when the priority of the GB-PUSCH is higher than the GF-PUSCH, the terminal device can determine the target channel from the multiple channels according to the relationship between the UCI transmitted by the terminal device and the uplink data transmitted by the terminal device. The way is divided into two.

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 the uplink data.

Specifically, the terminal device selects, according to the first indication information, a GF-PUSCH or a GB-PUSCH as the target channel, where the terminal device determines whether the uplink data is sent in the GB-PUSCH, and sends the uplink data in the GB-PUSCH. For the uplink data, the terminal device selects the GB-PUSCH as the target channel; if the uplink data is not sent by the GB-PUSCH, the terminal device determines whether to send the 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.

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 the uplink data on the GB-PUSCH nor transmits the uplink data on the GF-PUSCH, the terminal device selects the PUCCH as the target channel.

A detailed description of how the terminal device sends the UCI to the network device in the third mode will be described in detail below with reference to FIG.

As shown in FIG. 5, the specific process of the terminal device transmitting 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 uplink data needs to be sent in the current time slot.

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

540. If the GB-PUSCH data exists, the terminal device sends the UCI on the GB-PUSCH.

550. If the GB-PUSCH data does not exist, the terminal device sends the UCI on the 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 the presence of the GB-PUSCH data is equivalent to the case that the uplink data needs to be sent in the current time slot, and the terminal device determines whether the uplink data is sent on the GB-PUSCH, where the GB- The PUSCH data refers to uplink data that needs to be transmitted on the GB-PUSCH.

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

Specifically, as shown in FIG. 6, the specific process of the terminal device transmitting 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 uplink data needs to be sent in the current time slot.

630. If uplink data 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, then the terminal device sends all UCI or part of UCI on the GB-PUSCH;

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

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

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

In the fourth method, the terminal device does not need to determine 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 the GF-PUSCH or the GB-PUSCH as the target channel from the multiple channels according to the first indication information, and specifically includes: the terminal device selects the GB-PUSCH as the target channel.

It should be understood that, in the fourth method, after the terminal selects the GB-PUSCH as the target channel, the UCI may be separately transmitted on the GB-PUSCH after the UCI is transmitted on the GB-PUSCH, or the UCI may be simultaneously transmitted on the GB-PUSCH. And upstream data.

It should be understood that, in the foregoing, the terminal device may determine the target channel according to the priority information indicated by the first indication information. In fact, the terminal device may also determine the target channel in other manners, for example, the terminal device directly sends according to the current The type of UCI is used to determine the target channel.

Optionally, as an embodiment, in the foregoing step 210, determining, by the terminal device, the target channel from the multiple channels, the method includes: selecting, by the terminal device, a GF-PUSCH or a GB-PUSCH as the target channel according to the type of the UCI.

Optionally, when the terminal device selects the GF-PUSCH or the GB-PUSCH as the target channel according to the type of the UCI, according to the relationship between the UCI and the terminal device transmitting the uplink data, the terminal device may select the GF according to the type of the UCI. The -PUSCH or GB-PUSCH is divided into two cases as the target channel. The two cases will be described in detail below with reference to the third and fourth embodiments.

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

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

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

Specifically, as shown in FIG. 7, the specific process of the terminal device selecting the target channel according to the type of the UCI and transmitting 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 a type of UCI.

730. If the type of the UCI belongs to the first type, send the UCI on the GF-PUSCH.

740. When the type of UCI belongs to the second type, send 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 the fourth example, if the UCI is transmitted on the data channel, it must be transmitted together with the uplink data, that is, after determining the data channel corresponding to the UCI according to the type of UCI, it is necessary to further determine the data corresponding to the UCI. Whether there is uplink data on the channel needs to be transmitted. If there is no uplink data to be transmitted, UCI can be transmitted on the PUCCH.

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

Specifically, as shown in FIG. 8, the specific process of the terminal device selecting the target channel according to the type of the UCI and transmitting 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 a type of UCI.

830. In a case where the type of the 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 uplink data on the GF-PUSCH, the terminal device sends the UCI on the GF-PUSCH.

850. When the terminal device determines that the uplink data is not sent on the GF-PUSCH, the terminal device sends the UCI on the PUCCH.

860. In a case where the type of the 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 uplink data on the GB-PUSCH, the terminal device sends the UC on the GB-PUSCH.

880. When the terminal device determines that the uplink data is not sent on the GB-PUSCH, the terminal device sends the UCI on the PUCCH.

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

Specifically, the 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 (CSI), ACK, and NACK information.

The periodic information is similar to the configuration of the unlicensed resource. It is suitable for transmission on the GF-PUSCH. Non-periodic information, such as ACK/NACK, generally corresponds to dynamic scheduling and is suitable for transmission on the GB-PUSCH.

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

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

It should be understood that when the terminal device is configured with multiple GF-PUSCHs, the target GF-PUSCH used when transmitting the UCI may be determined from multiple GF-PUSCHs according to the indication of the network device, or may be determined by the terminal device itself. 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 transmits the UCI by adding a different sequence in 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 indicates 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 The two sequence indicates that the GF-PUSCH data only contains uplink data, and does not include UCI. In addition, in FIG. 9, when UCI is transmitted together with uplink data, UCI and uplink data occupy different time domain resources. In fact, as shown in FIG. 10, when UCI is transmitted together with uplink data, UCI can also occupy different frequency domain resources from the uplink data. That is to say, when UCI is transmitted through the GF-PUSCH channel, the UCI and the uplink data may be time division multiplexed or frequency division multiplexed. It should be understood that both the first sequence and the second sequence and the uplink data may be time division multiplexed or frequency division multiplexed.

The first sequence and the second sequence may be different 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. Detecting the RS sequence to determine whether the UCI is included in the GF-PUSCH data. If the network device detects the RS1 in the received GF-PUSCH data, the network device determines that the UCI is included in the GF-PUSCH (in this case, the GF-PUSCH data includes 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 include UCI (in this case, the GF-PUSCH data only includes uplink data).

When the terminal device is configured with multiple GF-PUSCHs, the terminal device can identify whether the UCI is included in the GF-PUSCH channel by adding different sequences in the GF-PUSCH data, so that the network device can be on the GF-PUSCH. The transmitted data is parsed correctly.

Optionally, when the terminal device sends the UCI on the GF-PUSCH, the uplink data may be sent only on the GF-PUSCH, and the uplink data and the UCI may be sent on the GF-PUSCH. To distinguish the two situations, the terminal The device may also indicate whether the GF-PUSCH channel transmits only UCI or both UCI and uplink data by transmitting different demodulation reference signals (DMRS) to the network device.

Specifically, when the terminal device sends the DMRS1 to the network device, it indicates that the GF-PUSCH data only includes the UCI and does not include the uplink data; and when the terminal device sends the DMRS2 to the network device, the GF-PUSCH data includes the UCI. It also contains upstream data.

The network device can determine the situation in which the terminal device sends the UCI according to the detected DMRS, and avoids an error when the network device identifies the GF-PUSCH data.

The method for transmitting UCI in the embodiment of the present application is described in detail from the perspective of the terminal device, and the method for transmitting UCI in the embodiment of the present application is described in the following with reference to FIG. It is to be understood that the method for transmitting UCI of the embodiment of the present application described from the perspective of the network device hereinafter corresponds to the method for transmitting UCI of the embodiment of the present application described above from the perspective of the terminal device, and is omitted as appropriate for the sake of brevity. Repeated description.

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 an authorized physical uplink shared channel GB-PUSCH.

It should be understood that in step 1110, the terminal device may determine the target channel from among the plurality of channels in the same manner as the terminal device. Specifically, the terminal device may arbitrarily select one channel from the GF-PUSCH and the GB-PUSCH as the target channel, and send indication information to the network device, where the indication information is used to indicate which channel the terminal device selects as the target channel, when the network After receiving the indication information, the device may 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.

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

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

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

The data is transmitted on the GB-PUSCH; if uplink data is 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 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 high, the terminal device further determines the target channel according to whether the GF-PUSCH has uplink data. The manner of determining the target channel is similar to the manner in which the terminal device determines the target channel in the first mode of the first example.

In this case, the network device determines the target channel and determines the terminal device in the third example above. The way the target channel is similar. It will not be described in detail here.

Optionally, the network device determines the target channel from the multiple channels, including: if the type of the UCI belongs to the first type, the network device determines whether uplink data is transmitted on the GF-PUSCH; if the uplink data is in the GF- On the PUSCH, the network device selects GF-PUSCH as the target channel; if the type of UCI belongs to the second type, the network device determines whether uplink data is transmitted on the GB-PUSCH; if uplink data is transmitted on the GB-PUSCH The network device selects the GB-PUSCH as the target channel; wherein the first type and the second type are different.
