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.

Abstract: Embodiments are provided for early termination of an iterative process of determining channel directions and transmissions in multi-user multiple-input and multiple-output (MU-MIMO) communications systems. In an embodiment, a base station or a user equipment (UE) calculates a multi-user channel matrix using a first iteration of a null-space singular value decomposition (SVD) based iterative zero-forcing (I-ZF) algorithm for multi-user MU-MIMO. The base station or UE repeats updating the multi-user channel matrix using a next iteration of the algorithm and the multi-user channel matrix calculated in a previous iteration, until the diagonal elements of the multi-user channel matrix are greater than the off-diagonal elements by a predefined threshold. Upon determining that the diagonal elements are greater than the off-diagonal elements by the predefined threshold, a plurality of transmission signals are calculated using the last updated multi-user channel matrix.

Abstract: Soft information for achieving interference cancellation in downlink transmissions can be communicated over device-to-device (D2D) links, thereby allowing paired user equipments (UEs) to receive downlink transmissions over the same radio resources. More specifically, paired UEs that receive transmissions over the same time-frequency resources may exchange soft or hard information over D2D links in order to facilitate interference cancellation. The D2D links may be unidirectional or bidirectional, and may be established over in-band or out-of-band resources. Paired UEs may be in the same or different cells, and may receive their respective transmissions from the same or different transmit point. UEs may be paired with one another based on various criteria, e.g., interference cancellation capabilities, scheduling metrics, etc.
