Abstract: Improved systems and techniques for communication in an environment in which muting of resources is used to avoid interference between cells. If a cell, represented by a macro eNB for example, is muting resources, those resources can be made available, under appropriate conditions, to user devices, such as UEs, engaging in device to device communication. Allocation of muted resources to D2D UEs can be based on meeting of conditions, such as that the D2D UEs be outside of a specified proximity to a cell, such as a small cell, using the resources, or that the D2D UEs transmit at less than a specified power. The UEs may take measurements to determine if the conditions are met and report the measurements to their base stations, which then determine whether to allocate the muted resources and configure the UEs with resource allocation information.

Abstract: The application relates to managing interference at the user equipment caused by femtocell base stations, such as home base stations, home E-UTRAN Node B base stations, and the like, configured with closed subscriber groups by allowing the user equipment to access a femtocell base station which would normally not allow access to the user equipment because the user equipment is not a member of the CSG being served by the femtocell base station. When a user equipment is within range of HeNB serving a CSG cell to which the user equipment is allowed access, referred to as the “allowed HeNB”, the user equipment may encounter severe interference from another, adjacent HeNB serving another CSG cell, which the user equipment may not be allowed access to, referred to as the “not allowed HeNB”, and which may have a stronger signal in terms of power than the HeNB including the CSG to which access is allowed.

Abstract: A user equipment UE selects between a first scanning mode and a second scanning mode using at least inputs of signal quality of a link with an access node and at least one of UE speed and network type of the access node. It then determines a scanning rate using the selected scanning mode and the UE speed, and detects and measures inter-frequency neighbor cells according to the determined scanning rate. In one example both modes the increase scanning rate for increased UE speeds, except that for the first mode speeds above Vt1 yield a zero scanning rate regardless of UE speed and for the second mode speeds above Vt2 yield a constant maximum scanning rate regardless of UE speed. In an embodiment the second mode is selected when the UE speed is >Vt1, and the signal quality is less than a predetermined minimum. Various other examples are detailed.
