Fig. 2 is a schematic block diagram of a transmission channel of an embodiment of the present invention.
Specifically, as shown in fig. 2, the method includes:
s210, the terminal equipment receives the data sent by the network equipment.
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 data sent by the network device, the terminal device sends a target uplink control channel to the network device on a target resource after the last symbol position occupied by the data.
In the embodiment of the invention, after receiving data sent by network equipment, the terminal equipment can directly determine the target resource (namely the resource used for sending the uplink control channel) after the last symbol position occupied by the data and send the target uplink control channel on the target resource, thereby avoiding the domain used for indicating the target resource from being specially configured in the control signaling, compressing the size of the control signaling and finally improving the reliability of the control signaling.
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 continuous symbols. For convenience of description, the unit of the target resource is taken 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: physical Uplink Control Channel (PUCCH).
The following describes a specific implementation of determining the target resource after the last symbol position occupied by the data:
in one embodiment, the terminal device may determine a first available uplink resource after a certain interval K after the last symbol position as the target resource.
For example, referring to fig. 3, U L represents uplink, D L represents downlink, and assuming that the data occupies the last symbol position of slot 0, the terminal device may determine slot 2 after a certain interval K after the last symbol position as the target resource.
In another embodiment, the terminal device may determine the target resource based on the processing capability of the terminal device and a time difference T1 between a starting symbol position of an uplink control channel on a first available uplink resource after a certain interval K after the last symbol position and the last symbol position.
In other words, the terminal device may select one available uplink resource between a first available uplink resource and a second available uplink resource after a certain interval K after the last symbol position as the target resource.
For example, referring to fig. 4, assuming that the data occupies the last symbol position of slot 0, the terminal device may select one of slot 2 and slot 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 a second available uplink resource after the specific interval K as the target resource.
Optionally, when the T1 satisfies 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 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 continuous N uplink symbols, wherein N is greater than or equal to the number of symbols indicated by the resource indication of the uplink control channel.
In the embodiment of the invention, the reliable transmission of the uplink control information 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 feed back the information to the network device as soon as possible; when the available uplink resource is continuous N uplink symbols, the reliability can be effectively ensured. Furthermore, when 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 N consecutive uplink symbols, the information can be fed back to the network device as early as possible on the premise of ensuring reliability. Optionally, when the same available uplink resource is configured for different terminal devices, code resources may be configured for different terminal devices to multiplex the available uplink resource.
It should also be understood that, in the foregoing embodiment, the terminal device selects one available uplink resource between the first available uplink resource and the second available uplink resource as the target resource only by way of an exemplary description, and the embodiment of the present invention is not limited thereto.
As an embodiment, the terminal device may determine the target resource without considering the collision problem, only considering the processing capability of the terminal device, and the time difference T1 between the starting symbol position of the uplink control channel after the certain interval K after the last symbol position and the last symbol position.
In other words, the terminal device may select one uplink resource between a first uplink resource and a second uplink resource after a certain interval K after the last symbol position as the target resource.
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 from slot 1 and 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. 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 preconfigured, or the specific interval K may also be configured through the network device signaling. Alternatively, 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 (e.g., PDSCH) is located.
For example, assuming that the starting symbol position (e.g. PUCCH starting symbol position) of the uplink control channel is 13, the last symbol position of the data (e.g. 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 may be the slot in which the PDSCH is located. Assuming that the starting symbol of the starting symbol position (PUCCH starting symbol position) of the uplink control channel is 8, the last symbol of the data (e.g. PDSCH) is 8, the time for the terminal device to demodulate the PDSCH is 2 symbols, and since 8-8<2, the target resource may be the next slot of the 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 a certain condition is met.
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 a threshold L, where the threshold L is a non-negative number.
It should be understood that, for brevity, 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, and are not described herein again.
As shown in fig. 6, the method for the network device to receive the channel may include the following:
s310, sending data to the terminal equipment;
s320, determining a target resource after the last symbol position occupied by the data;
