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 the 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 the target resource (that is, the resource used for sending the uplink control channel) after the last symbol position occupied by the data, and in the target resource. The target uplink control channel is sent, and the domain for indicating the target resource is specifically configured in the control signaling, the size of the control signaling is compressed, and finally the reliability of the control signaling is improved.

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 a plurality of consecutive symbols. For convenience of description, the following takes the unit of the target resource as a time slot as an example. It should be understood that the data in the embodiment 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 (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 an 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 indicates uplink, DL indicates downlink, and assumes that the data occupies the last symbol position of slot 0, and the terminal device can determine slot 2 after the specific interval K after the last symbol position. For this target resource.

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

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

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

Optionally, when the T1 does not meet 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 resource satisfies at least one of the following conditions:

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 a continuous N uplink symbol, 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 reliability transmission of the uplink control information can be ensured by designing the available uplink resources. Further, when the start 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 feed the information to the network device as soon as possible; the available uplink resource is a continuous N uplink. When the symbol is used, reliability can be effectively guaranteed. Further, 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 a continuous N uplink symbol, the reliability can be ensured as early as possible. The information is fed back to the network device. In addition, by configuring the same available uplink resources for different terminal devices, the multi-user can be used to reuse the available uplink resources. 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 resources.

It should be further 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, which is only an exemplary description. Limited to this.

As an embodiment, the terminal device may consider the processing capability of the terminal device regardless of the collision capability, 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 between the determination of 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 the specific interval K after the last symbol position.

For example, referring to FIG. 5, assuming that the data occupies the last symbol position of slot 0, the terminal device may select one slot in slot 1 and slot 2 after the 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. For another example, when the T1 satisfies 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 by the network device signaling. Optionally, the specific interval K may be related to the processing capability of the terminal. Alternatively, 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 that the start symbol position (for example, the PUCCH start symbol position) of the uplink control channel is 13, the last symbol position of the data (for example, PDSCH) is 8, and the time required for the terminal device to demodulate the PDSCH is 2 symbols. When 13-8>2, the target resource may be the time slot in which the PDSCH is located. It is assumed that the start symbol position of the uplink control channel (PUCCH start symbol position) start symbol is 8, the last symbol of data (for example, PDSCH) is 8, and the time for the terminal device to demodulate the PDSCH is 2 symbols, since 8-8 <2, therefore, the target resource can be the next time slot of the time slot in which 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 satisfying 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 location of the target resource and the last symbol location is less than or equal to the threshold L. Wherein, the threshold L is a non-negative number.

It should be understood that the steps in the method for the network device to receive the channel may refer to the corresponding steps in the method for the terminal device to send the channel. For brevity, no further details are provided herein.

As shown in FIG. 6, the method for a network device to receive a channel may include the following:
