System and Method for Downlink Open-Loop Multi-User Coordinated Multipoint Transmission Using Sparse Code Multiple Access

摘要

Embodiments are provided to enable downlink open-loop multi-user coordinated multipoint (MU-CoMP) transmission using sparse code multiple access (SCMA). In an embodiment, a network controller selects, in a cluster of multiple transmission points (TPs) and multiple user equipment (UEs), a MU-CoMP with SCMA transmission mode and a UE paring scheme for data transmission from a set of TPs to a set of UEs. The controller schedules the set of UEs for data transmission from the set of TPs, including coordinating and allocating, for each TP in the set of TPs, a plurality of SCMA layers to the UEs in accordance with the selected MU CoMP with SCMA transmission mode. The controller also determines values for control signaling based on the scheduling. The control signaling configures the set of UEs to detect the data transmission from the TPs.

1. A method for enabling open-loop multi-user coordinated multipoint (CoMP) transmission using sparse code multiple access (SCMA), the method comprising:
scheduling, for a cluster of multiple transmission points (TPs) and multiple user equipment (UEs), a set of UEs for data transmission from a set of TPs by coordinating and allocating, for each TP in the set of TPs, a plurality of SCMA layers to the set of UEs in accordance with a MU CoMP with SCMA transmission mode and a UE paring scheme, wherein the MU CoMP with SCMA transmission mode and the UE paring scheme are selected in accordance with a criterion; and assigning to the set of TPs a control signaling for configuring the set of UEs to detect the data transmission from the set of TPs, wherein the control signaling indicates a plurality of parameters based on the scheduling.
