Title:
FLEXIBLE SINGLE CARRIER WAVEFORMS
Document Type and Number:
WIPO Patent Application WO/2020/231634
Kind Code:
A3
Abstract:
Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) or a base station to transmit and receive single carrier (SC) waveforms (e.g., corresponding to uplink or downlink transmissions) using an SC transmission configuration. In some cases, a UE and a base station may employ an SC configuration to identify resource elements (REs) for uplink or downlink SC signals. Additionally or alternatively, the UE and the base station may employ an SC configuration with a different cyclic prefix (CP) length in order to change a base amount of REs that may be allocated for an SC transmission, where the different CP length may be either static or dynamic. The base station may transmit an indication of an SC configuration to the UE, and the UE and the base station may process corresponding SC downlink or uplink communications according to the indicated SC configuration.
