Problems solved by technology

exist figure 1 In the situation shown, the terminal cannot send uplink signals on subframes "6" and "7" on the LTE uplink (Uplink, UL) carrier, and the terminal cannot respond to the LTE downlink (Downlink) corresponding to ACK / NACK. , DL) The downlink signal received on the "2" and "3" subframes is fed back, which will seriously affect the performance of the LTE downlink
Therefore, for a DC terminal, when the terminal sends an uplink signal on the NR carrier, the terminal cannot feed back the ACK / NACK of the downlink data received in all downlink subframes in LTE mode

Abstract

An embodiment of the present invention provides a physical uplink control channel PUCCH sending method, a receiving method, and related equipment, wherein the PUCCH sending method includes: the terminal equipment determines N1 pieces of feedback information; the N1 pieces of feedback information correspond to N1 downlink time units; the terminal equipment Determine physical uplink control channel PUCCH resources and N2 bits according to the N1 pieces of feedback information; the PUCCH resources and N2 bits jointly indicate the combination status of N3 pieces of feedback information, N1, N2, and N3 are positive integers, and N3 is less than or equal to N1; The terminal device carries the N2 bits on the PUCCH resource and sends them to the network device. Implementing the embodiments of the present invention can enable DC terminals to feed back ACK / NACK of downlink data received in all downlink subframes in LTE mode while sending uplink signals on the NR carrier, improving the reliability of the communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending and receiving a physical uplink control channel and related equipment. Background technique [0002] During the development and evolution of the wireless communication system, a 5G New Radio Interface (NR) system and a Long Term Evolution (LTE) system can be deployed simultaneously on a frequency band below 6 GHz. A terminal working in NR and LTE dual connectivity (Dual Connectivity, DC) mode only sends uplink signals on one frequency point at the same time, so that the terminal cannot be in the LTE uplink subframe that has time overlap with the NR uplink time slot / slot to send the signal on. Specifically, such as figure 1 As shown, the terminal working in DC mode needs to send the NR system's acknowledgment (Acknowledgment, ACK) / negative acknowledgment (Negative Acknowledgment, NACK) in the time slots marked "U" and "S" on the NR carrier, s...
