Abstract: A paging method and system in a wireless network for a target device that is enabled to transition between an active state and a standby state, including: tracking a location of a target device within the network while the target device is in the standby state based on a periodic identifying signal from the target device; determining a serving transmission point for the target device based on the tracking; and instructing the serving transmission point to transmit a paging message to the target device.

Abstract: Embodiments of the present invention provide a systematic solution to virtual random access (VRA) that dynamically and adaptively forms various metrics. The present invention facilitates dynamic data pipelining between the network-side and the UE-sides without the need to use the same cell-association concept as current wireless networks and provides soft associations between dynamic groups of UEs and TPs based on various UE, TP, and network related metrics. To provide efficient collaborative grouping and association among TPs and UEs, the present invention features a soft TP-UE association map based on several factors, such as individual UE metrics, TP metrics, effects of neighboring or nearby UEs (e.g., interference), and historical network knowledge.

Abstract: In one embodiment, a method for adaptive transmission time intervals (TTIs) includes transmitting, by a communications controller to a user equipment (UE), a segment of a first TDD TTI configuration of a first TDD interval and a second TDD TTI configuration of the first TDD interval, where the first TDD TTI configuration has a first pattern, where the second TDD TTI configuration has a second pattern, where the first pattern is different than the second pattern, where the first TDD TTI configuration has a first uplink TTI segment and a first downlink TTI segment. The method also includes transmitting a first plurality of data on a first TTI in the first downlink TTI segment of the first TDD TTI configurations of the first TDD interval and receiving a second plurality of data on the first uplink segment of the first TDD TTI configuration of the first TDD interval.

Abstract: An embodiment method includes identifying a plurality of VTP configurations representing allocations of TPs among a plurality of VTPs each having at least one TP. Potential serving VTPs are then identified for a selected UE in a plurality of UEs according to at least one UE centric criterion. The potential serving VTPs are selected for each of the plurality of VTP configurations. A UE measurement set is then scheduled for the potential serving VTPs for a scheduled channel resource according to measurement parameters. The method further includes selecting a serving VTP configuration from the plurality of VTP configurations according to UE measurement feedback from the selected UE.
