Abstract: System and method embodiments are provided to support network communications with groups of UEs. The embodiments include a two-level group-based hybrid-automatic repeat request (HARQ) mechanism and acknowledgement (ACK)/negative ACK (NACK) feedback. An embodiment method includes receiving, at a UE within a virtual multi-point (ViMP) comprising UEs, a data packet for a target UE (TUE) that is broadcasted from a base station (BS) to the ViMP node, decode the data packet, and upon successfully decoding the data packet, broadcasting the data packet to the UEs within the ViMP node until a timer pre-established by the BS expires or an ACK message is received from the TUE or the ViMP node. In an embodiment, broadcasted data received in the ViMP node is re-broadcasted upon receiving a negative acknowledgment (NACK) message from the TUE, a beacon UE, or any of the UEs within the ViMP node.

Abstract: Method and apparatus for decoding a transmitted signal by a receiver in a MIMO system into a first estimate component for estimating a first signal, a first interference component indicating interference resulting from a correlation relationship among a set of signals to be transmitted, and a first noise component. A base station generates the transmitted signal from the set of signals through a coding process, the coding process defining a correlation relationship amongst the set of signals. The correlation information about the correlation relationship is transmitted to the receiver directly or by a dedicated reference symbol. The decoding is performed by determining a linear receiver filter for the first signal in accordance with the correlation information, and de-correlating the first signal and interferences.

Abstract: Transmit point (TP) associations can be assigned to user equipments (UEs) by including a TP association variable within a sum-utility function traditionally used for computing beamforming weight vector assignments. Accordingly, maximization of the sum-utility function obtains both TP associations and beamforming weight vector assignments. Additionally, the sum-utility function may be computed in accordance with channel statistics, rather than channel state information (CSI), thereby reducing coordinated multi-point transmission (CoMP) related overhead.

Abstract: Embodiments of the invention describe a novel solution to enhance network service to devices with limited or no connectivity. Embodiments include network-aware nodes deployed by an end-user or operator which are configured by a network to achieve enhanced coverage, enhanced throughput, enhanced battery life, and mitigation of cell boundary experiences, etc. Embodiments provide these benefits to a specified or non-specified set of user equipment (e.g., neighboring user equipment). The service expansion terminal can be an available user equipment that is idle and that has been volunteered, assigned, or is a dedicated node with limited user interface and designed for carrying out enhanced coverage, enhanced throughput, enhanced battery life, and the mitigation of cell boundary experiences, etc. Embodiments may therefore provide low-cost, flexible deployment, and mobility thereby enabling boundaryless service.

Abstract: Embodiments are provided for a compress and forward relaying scheme in joint multi-cell processing. A plurality of base stations receive similar combinations of user signals from a plurality of users, compress the signals using quantization, and relay the signals over respective backhaul links to a processor in the network for decoding the signal. The processor determines suitable quantization noise levels for the backhaul links according to a weighted sum-rate maximization function for optimizing the quantization noise levels, subject to a backhaul sum capacity constraint on the backhaul links. The determined quantization noise levels are sent to the base stations, which then quantize the received combinations of user signals according to the quantization noise levels and relay the quantized signals to the processor. The quantization is according to a Wyner-Ziv coding or a single user compression algorithm that excludes statistical correlations between the user signals at the base stations.
