Abstract: Systems and methods for establishing transmission format parameters between communication devices are provided. In some aspects, a method includes identifying, by a first base station, a first communication session with a first user equipment. A master set of transmission format parameters is shared between the first base station and the first user equipment. The method also includes assigning a first subset of the master set of transmission format parameters to the first communication session. The first subset is specifically assigned to the first communication session and specifies which of the master set of transmission format parameters is allocated for use in the first communication session. The method also includes transmitting an indicator of the first subset to the first user equipment.

Abstract: Systems and methods for efficient link adaptation in multi-access wireless communication networks, including link adaptation in scenarios with non-collocated and/or power imbalanced base station transmit antennas are provided. In an embodiment, an indication of signal powers of the transmit antennas is signaled by the network to the user equipment (UE) when the UE is configured for logical antenna. ports using non-collocated and/or power imbalanced transmit antennas. The UE can use the indication of signal powers in determining the Precoding Matrix Indicator (PMI) and the Channel Quality Indicator (CQI), resulting in higher accuracy link adaptation.

Abstract: Embodiments provide systems and methods for interference management in wireless multi-access communication networks, and more particularly systems and methods to enable reduction and/or suppression of interference. Embodiments for interference reduction include, without limitation, systems and methods to enable interference alignment, interference avoidance, and/or joint transmission to a user equipment (UE). Embodiments for enabling suppression of interference include, without limitation, systems and methods for feedback (from a UE to a network) or feedforward (from the network to the UE) signaling to enable interference estimation at the network/UE.

Abstract: Systems using a transmit precoder codebook designed for a four-transmitter (4Tx) antenna configuration are described. The 4Tx antenna configuration is an attractive option for base stations in cellular network environments due to site-acquiring advantages and robust performance. In an embodiment, the transmit precoder codebook can be used for a variety of transmit antenna configurations and has a high resolution to enable beamforming and/or nulling. In another embodiment, the transmit precoder codebook is a two-component codebook, with a first precoder component signaled at a first frequency and a second precoder component signaled at a second higher frequency.
