Embodiment Construction

[0055] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0056] This application is mainly applied to the 5th generation wireless communication system (new radio, NR) system, and can also be applied to other communication systems, such as narrow band-internet of things (NB-IoT,) system, machine type communication (machine type communication, MTC) system, future next-generation communication system, etc.

[0057] The network elements involved in this embodiment of the present application include terminal devices and network devices. Such as figure 1 As shown, the network device and the terminal device form a communication system. In the communication system, the network device sends information to the terminal device through a downlink channel, and the terminal device sends information to the network device through an uplink channel. Among them, the terminal device may be a mobile phone, a tablet computer, a computer w...

Abstract

A method and apparatus for sending and receiving a HARQ-ACK message, the method comprising: a terminal device selecting a first PUCCH resource from at least one first PUCCH resource set based on a first sub-time unit; wherein the first sub-time unit refers to The sub-time unit where the HARQ-ACK message is located, the first PUCCH resource refers to the PUCCH resource in the first sub-time unit, and at least one first PUCCH resource set is configured by the network device for the terminal device based on the time unit; The PUCCH resource sends a HARQ‑ACK message to the network device. Using the above method can avoid a large number of reconfiguration of high-layer signaling and abnormal situations such as PUCCH resources falling outside the sub-time unit or PUCCH resources crossing the time unit boundary.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for sending and receiving HARQ-ACK messages. Background technique [0002] Mobile communication technology has profoundly changed people's lives, but people's pursuit of higher performance mobile communication technology has never stopped. In order to cope with the explosive growth of mobile data traffic in the future, massive mobile communication device connections, and various new services and application scenarios emerging, the fifth generation (5G) mobile communication system has emerged as the times require. The International Telecommunication Union (ITU) has defined three major application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable and low latency communication (ultra reliable and low latency) communications, URLLC) and massive machine type communications (mMTC).
