Abstract: Embodiments are provided to serve user equipments (UEs) that experience, for example persistently, inter-transmission point group (TPG) interference in a wireless or cellular network. The embodiments include steps to serve edge UEs (EUs) such as persistent EUs (PEUs) using a set of transmission points (TPs) in one or more TPGs. The selected set of TPs used for serving the EUs or PEUs are dynamically determined based on a UE-centric metric. The metric involves the PEUs and surrounding UEs. The UE-centric metric is used to partition the network to multiple TPG sets. For each one of multiple assigned resource units (RUs), a TPG set that maximizes or improves a network-wide utility is used for scheduling transmissions. Further, for each RU, the UEs are associated with an optimized or improved TPG in the used TPG set.

Abstract: Efficient D2D link integration can be achieved by allowing mobile devices to independently initiate D2D/connection-proxy discovery without re-broadcasting beacons originating from the wireless access point. A mobile station wanting to establish a D2D link may broadcast a search message to neighboring mobile stations, which may return offer messages specifying a connection quality and/or parameters of the candidate indirect connection. The requesting mobile station may then select one of the responding neighboring mobile stations through which to establish the indirect connection. Responding mobile stations may delay offer message transmission by a period that is proportional to a connection quality to reduce offer message redundancy.

Abstract: Crosstalk can be reduced in optical waveguide bundles by varying the widths of individual waveguides. Using different width waveguides reduces the growth of crosstalk between the optical waveguides, thereby allowing the waveguides to be placed in closer proximity to increase waveguide density on the chip and/or reduce the routing space required for the waveguide bundle. Moreover, varying the width of a waveguide spiral may reduce crosstalk, which can increase power efficiency when implemented in coiled or folded waveguide thermal optical (TO) devices.
