FIG. 2 is a schematic block diagram of a transmission channel according to an embodiment of the present invention.

Specifically, as shown in FIG. 2, the method includes:

S210. The terminal device receives data sent by the network device.

S220. The terminal device determines a target resource after the last symbol position occupied by the data.

S230. The terminal device sends a target uplink control channel to the network device on the target resource.

In short, after receiving the data sent by the network device, the terminal device sends the target uplink control channel to the network device on the target resource after the last symbol position occupied by the data.

In the embodiment of the present invention, after receiving the data sent by the network device, the terminal device may directly determine a target resource (that is, a resource for sending an uplink control channel) directly after the last symbol position occupied by the data, and Sending the target uplink control channel on the resource can further avoid the special configuration of the domain indicating the target resource in the control signal, compress the size of the control signal, and ultimately improve the reliability of the control signal.

It should be understood that the unit of the target resource in the embodiment of the present invention may be a time slot, or may be multiple consecutive symbols. For ease of description, the following uses the unit of the target resource as a time slot as an example. It should also be understood that the data in the embodiments of the present invention may include, but is not limited to, a Physical Downlink Shared Channel (PDSCH), and the uplink control channel may include, but is not limited to: a Physical Uplink Control Channel, PUCCH).

The following describes the specific implementation of determining the target resource after the last symbol position occupied by the data:

In one embodiment, the terminal device may determine the first available uplink resource after the specific interval K after the last symbol position as the target resource.

For example, referring to FIG. 3, UL means uplink and DL means downlink. Assuming that the data occupies the last symbol position of time slot 0, the terminal device can determine time slot 2 after specific interval K after the last symbol position For that target resource.

In another embodiment, the terminal device may be based on the processing capability of the terminal device and the starting symbol position of the uplink control channel on the first available uplink resource after a specific interval K after the last symbol position and the The time difference T1 between the last symbol positions determines the target resource.

In other words, the terminal device may select an available uplink resource as the target resource between the first available uplink resource and the second available uplink resource after a specific interval K after the last symbol position.

For example, referring to FIG. 4, assuming that the data occupies the last symbol position of time slot 0, the terminal device may select one of the time slots 2 and 3 after a specific interval K after the last symbol position as The target resource.

Optionally, when the T1 does not satisfy the processing capability of the terminal device, the terminal device may determine the second available uplink resource after the specific interval K as the target resource.

Optionally, when the T1 meets the processing capability of the terminal device, the terminal device may determine the first available uplink resource after the specific interval K as the target resource.

It should be understood that the available uplink resources meet at least one of the following conditions:

The starting symbol of the available uplink resource is earlier than the symbol indicated by the resource indication of the uplink control channel; and the available uplink resource is consecutive N uplink symbols, where N is greater than or equal to the symbol indicated by the resource indication of the uplink control channel number.

In the embodiment of the present invention, the reliable transmission of uplink control messages can be ensured by designing the available uplink resources. Further, when the starting symbol of the available uplink resource is earlier than the symbol indicated by the resource indication of the uplink control channel, the terminal device can make the network device return the message as quickly as possible; the available uplink resource is N consecutive When uplink symbols are used, reliability can be effectively guaranteed. Furthermore, when the start symbol of the available uplink resource is earlier than the symbol indicated by the resource indication of the uplink control channel, and the available uplink resource is consecutive N uplink symbols, it can be as early as possible on the premise of ensuring reliability. Feedback the information to the network equipment. In addition, by configuring the same available uplink resource for different terminal equipment, multiple users can reuse the available uplink resource. Optionally, when the same available uplink resource is configured for different terminal devices, code resources may be configured for different terminal devices to reuse the available uplink resource.

It should also be understood that, in the foregoing embodiment, the terminal device selects an available uplink resource as the target resource between the first available uplink resource and the second available uplink resource. The target resource is only an exemplary description, and the embodiment of the present invention does not Limited to this.

As an embodiment, the terminal device may not consider the collision problem, but only consider the processing capability of the terminal device, and the start symbol position and the last symbol position of the uplink control channel after the specific interval K after the last symbol position. The time difference T1 determines the target resource.

In other words, the terminal device may select an uplink resource as the target resource between the first uplink resource and the second uplink resource after a specific interval K after the last symbol position.

For example, referring to FIG. 5, assuming that the data occupies the last symbol position of time slot 0, the terminal device may select one time slot from time slot 1 and time slot 2 after a specific interval K after the last symbol position as The target resource.

For example, when the T1 does not satisfy the processing capability of the terminal device, the terminal device may determine the second uplink resource after the specific interval K as the target resource. As another example, when the T1 meets the processing capability of the terminal device, the terminal device may determine the first uplink resource after the specific interval K as the target resource.

It should be understood that the specific interval K involved in the embodiment of the present invention may be pre-configured, or the specific interval K may also be configured through the network device signal. Optionally, the specific interval K may be related to the processing capability of the terminal. Optionally, the specific interval K may be a non-negative number. It should be noted that when the specific interval K is 0, the target resource may be a time slot in which the data (for example, PDSCH) is located.

For example, suppose the starting symbol position of the uplink control channel (such as the PUCCH starting symbol position) is 13, the last symbol position of the data (such as PDSCH) is 8, and the time required for the terminal device to demodulate the PDSCH is 2 symbols. Since 13-8> 2, the target resource can be the time slot where the PDSCH is located. Assume that the starting symbol position of the uplink control channel (PUCCH starting symbol position) is 8. The last symbol of the data (for example, PDSCH) is 8. The time for the terminal device to demodulate the PDSCH is 2 symbols. <2, therefore, the target resource can be the next time slot of the time slot where the PDSCH is located.

Further, in S230 shown in FIG. 1, the terminal device may send the target uplink control channel to the network device after meeting certain conditions.

For example, as an embodiment, the terminal device may send the target uplink control channel to the network device on the target resource when the interval between the position of the target resource and the last symbol position is less than or equal to the threshold L. , Where the threshold L is a non-negative number.

It should be understood that, for the steps in the method for the network device to receive the channel, reference may be made to the corresponding steps in the method for the terminal device to send the channel. For brevity, details are not described herein again.
