Problems solved by technology
However, although using PDCCH to dynamically schedule the frequency domain resources used to transmit PUCCH can use frequency selective scheduling to improve the performance of PUCCH links and improve the efficiency of uplink resource utilization, but complete dynamic scheduling will cause great complexity in the implementation of network equipment. The problem of high signaling overhead

The present application discloses a method for transmitting an uplink control channel, a network device and a terminal device. The method includes: the network device sends the downlink control channel to the terminal device in the first downlink frequency domain control area, and the downlink control channel includes the first One piece of configuration information, the first configuration information is used to dynamically instruct the terminal device to send at least one first uplink frequency domain control region used by the network device to send the uplink control channel; the network device in at least one first uplink frequency domain control region each The first uplink frequency domain scheduling unit in the first uplink frequency domain control area receives the uplink control channel sent by the terminal device, and the frequency domain position of the first uplink frequency domain scheduling unit in the first uplink frequency domain control area is based on the first The downlink frequency domain control area is determined. The present application adopts a combination of dynamic scheduling and implicit indication to determine frequency domain resources for transmitting uplink control channels, which can reduce scheduling complexity and reduce signaling overhead.
Description
technical field [0001] The present application relates to the communication field, and more specifically, to a method for transmitting an uplink control channel, a network device and a terminal device. Background technique [0002] In a Long Term Evolution (LTE) system, a physical uplink control channel (Physical Uplink Control CHannel, PUCCH) used to transmit positive (ACKnowledgment, ACK) / negative (Negative ACKnowledgment, NACK) confirmation information or other uplink control information The resource is mapped implicitly by the position of the physical downlink control channel (Physical Downlink Control CHannel, PDCCH). The position of the PUCCH for transmitting a certain terminal device is determined by the first Control Channel Element (CCE) of the PDCCH that schedules resources for the terminal device, wherein each CCE has a fixed mapping position in the PUCCH. [0003] Although the use of implicit mapping to indicate resources for transmitting PUCCH can save signalin...
