Title:
METHODS OF ENABLING MULTIUSER SUPERPOSITION TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2017/020846
Kind Code:
A1
Abstract:
Methods of enabling multiuser superposition transmission (MUST) in LTE systems are proposed. MUST operation allows simultaneous transmission for multiple co-channel users on the same time-frequency resources. A higher-layer signaling is used for configuring a UE to enable MUST in each transmission mode (TM). MUST is a sub-TM of each TM. When a UE is configured by higher layer to enable MUST, the UE will monitor new DCI formats supported by the configured TM with new fields carrying scheduling information of another co-channel UE. Dynamic switching between MUST and non-MUST operation is allowed. Mixed transmission schemes and precoders among co-channel UEs are also supported.
