  • the embodiments of the present application relate to the technical field of wireless communication.
  • New Radio introduces a variety of uplink control channel formats to deal with different scenarios.
  • NR introduces a flexible uplink information transmission mechanism to improve system performance.
  • NR can support a central emission frequency of up to 52.6 GHz, in high-frequency scenarios, due to the poor diffraction ability of high-frequency signals, it is easy to be affected by blockage.
  • Such channel quality degradation due to occlusion is very unfavorable for low-latency and high-reliability (URLLC) services. This is because the communication delay requirement of the URLLC service is generally less than 3 milliseconds. If the transmission of the uplink control information is affected by the blocking, the delay requirement of the URLLC may not be met.
  • a feasible way is to send the uplink control information in a spatial diversity manner. That is to say, on the user equipment (UE) side, the same data can be sent in different time domain uplink transmission opportunities (or called physical uplink control channel repetition, that is, PUCCH repetition), via different airspace paths or via different transmission opportunities and reception point (transmission and reception point, TRP) to reach the base station.
