Abstract: Embodiments disclosed herein provide a fairness and complexity-constrained uplink NOMA scheme. For example, various embodiments set the power/resource allocation for a particular UE (e.g., a weak UE) such that the minimum rate requirement of the UE is guaranteed, independently of the activation status of another UE (e.g., a strong UE). Additionally, in some embodiments the access point selects whether the UE uses a NOMA or OMA depending on the relative performance gain/cost of NOMA.

Abstract: Embodiments disclosed herein provide an adaptive multiple access scheme. In some embodiments, a UE transmits a message according to a first multiple access scheme and retransmits the message according to a second multiple access scheme. In some embodiments, an access point (AP) receives a message transmitted by the UE according to the first multiple access scheme and receives the message retransmitted by the UE according to the second multiple access scheme.

Abstract: A CSI-constrained UE grouping system for dense uplink NOMA systems. For example, a network node (e.g., an access point, such as a base station) determines which UEs should be grouped based on the uplink (UL) rate demand (UL traffic demand), and sends appropriate parameters to those UEs for UL transmission.

Abstract: A method for integrating access and backhaul links, the method includes: obtaining information indicating a data rate requirement for a link between a first AP and a second AP; obtaining information indicating a gain of the link between the first AP and the second AP; computing, using the gain of the link, an achievable data rate for the link between the first AP and the second AP, wherein the achievable data rate is computed based on an OMA scheme; determining that the data rate requirement is greater than the achievable data rate; and as a result of determining that the data rate requirement is greater than the achievable data rate, pairing a first UE with the first AP, such that a NOMA scheme is used for the link between the first AP and second AP and the link between the first AP and the first UE.

Abstract: According to some embodiments, a method of synchronizing a wireless device with a network node comprises receiving a radio subframe transmitted from the network node. The MBSFN radio subframe comprises a first Primary Synchronization Signal (PSS) associated with a first Orthogonal Frequency Division Multiplexing (OFDM) symbol and paired with a first Secondary Synchronization Signal (SSS) associated with a second OFDM symbol. The method further comprises detecting the first PSS and detecting the first SSS within the radio subframe. The method determines system information associated with the network node based on the detected PSS and SSS. The radio subframe is transmitted from the network node as a Multimedia Broadcast Multicast Services Single-Frequency Network (MBSFN) subframe.

Abstract: There is provided mechanisms for adaptive beamforming. A method is performed by a first network device. The method comprises acquiring beamforming information indicating spatial directions in which an identification signal is to be transmitted.

The identification signal is transmitted such that the identification signal occupies a larger portion of communications resources when transmitted in spatial directions with high second network device presence than in spatial directions with low second network device presence.
