Abstract:
1. A method of operating a user equipment, comprising: obtaining a number of channel state information bits (CSI bits) for a channel state information (CSI); obtaining a number of hybrid automatic repeat request acknowledgement bits (HARQ-ACK bits) for hybrid automatic repeat request acknowledgement (HARQ-ACK); determining whether spatial bundling for the HARQ-ACK bits is applied based on at least the number of CSI bits and the number of HARQ-ACK bits; in a case that the spatial bundling for the HARQ-ACK bits is applied, performing spatial bundling for the HARQ-ACK bits and transmitting the CSI and the spatial bundled HARQ-ACK on a physical uplink control channel (PUCCH); and in a case that the spatial bundling for the HARQ-ACK bits is not applied, transmitting the CSI and the HARQ-ACK which is not spatial bundled on the PUCCH.
