Description

TECHNICAL FIELD The disclosure relates generally to wireless communications, including but not limited to methods and devices for determining PUCCH of delayed HARQ-ACK codebook. BACKGROUND The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called 5G New Radio (5G NR) as well as a Next Generation Packet Core Network (NG-CN or NGC). The 5G NR will have three main components: a 5G Access Network (5G-AN), a 5G Core Network (5GC), and a User Equipment (UE). In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based, and some being hardware based, so that they could be adapted according to need. 3GPP DRAFT; R1-2008941 discloses that, in case PUCCH resource for SPS HARQ-ACK is not available due to collision with DL symbol or flexible symbol, the HARQ-ACK for SPS PDSCH will be delayed to next available PUCCH resource. 3GPP DRAFT; R1-2008159 discloses that a UE determines a set of SPS PDSCHs with corresponding HARQ-ACK information provided by a PUCCH transmission and a PUCCH resource for the PUCCH transmission based on Kl value, and semi-static TDD configuration.
