Title:
BEAM INDICATIONS FOR A SINGLE FREQUENCY NETWORK (SFN)
Document Type and Number:
WIPO Patent Application WO/2022/052027
Kind Code:
A1
Abstract:
This disclosure provides systems, methods and apparatuses for beam indications in a single frequency network (SFN). In one aspect, a user equipment (UE) may be provided with a set of multiple uplink beam indications for an SFN and a set of multiple downlink beam indications for the SFN. The set of multiple uplink beam indications and the set of multiple downlink beam indications can be indicated to the same antenna port of the UE for one or more communication channels (for example, data channels or control channels) or one or more reference signals (for example, demodulation reference signals (DMRSs), sounding reference signals (SRSs), channel state information reference signals (CSI-RSs), or positioning reference signals (PRSs) ). As a result, the UE and a base station (BS) may reduce signaling and network overhead associated with beam indications in the SFN.
