Abstract:
Apparatus and methods are provided for RE allocation for UCI on PUSCH. In one novel aspect, the UE encodes UCI for transmission on PUSCH in a NR network. The UE allocates UCI REs onto the PUSCH following one or more UCI RE allocation rules including (a) using same logical allocation patterns for both CP-OFDM waveforms and DFT-S-OFDM waveforms, (b) distributing the UCI REs across a time domain of the PUSCH, and (c) distributing the UCI REs across a frequency domain for CP-OFDM or across a virtual-time domain for DFT-S-OFDM. In one embodiment, the HARQ-ACK REs are distributed across the time domain as much as possible. In another embodiment, the allocation of the HARQ-ACK REs further involves calculating the number of HARQ REs dynamically for the HARQ ACK. The number of HARQ REs is based on a weighting parameter, which is either configured or obtained through system information.
