EQUIPMENT FOR REPEATING THE UP-LINK CONTROL PHYSICAL CHANNEL (PUCCH) TO INCREASE THE RELIABILITY OF THE PUCCH LINK AND MEMORY MEDIA

Abstract

The user equipment (UE) can increase the reliability of the channel transmission, the physical uplink control (PUCCH) by transmitting repeated copies of the PUCCH, in a repetition pattern spanning one or more slots. In in-slot mode, multiple copies can be transmitted in each configured slot, with or without frequency hopping. The number of copies as well as the time interval between consecutive copies can be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In between-slot mode, one copy is transmitted per configured slot. Different copies can be transmitted in different directions, in a spatially consistent pattern. The UE can perform repeated transmission of PUCCHs to different transmit-receive points (TRPs) by using different time progression and / or transmission power levels accordingly.
