Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.

Abstract: Technology for reducing buffer overflow at a Third Generation Partnership Project (3GPP) Serving Gateway (S-GW) is described. A buffer overflow message may be received, at an evolved node B (eNB) from the S-GW, indicating potential overflow of downlink information at an S-GW buffer. The downlink information may be stored at the S-GW buffer until a plurality of user equipments (UEs) awake from a low power mode during a discontinuous reception (DRX) sleep cycle. One or more UEs may be selected from the plurality of UEs according to predefined criteria, wherein the one or more UEs are in a connected mode. The DRX configurations of the one or more UEs may be modified in order to reduce the downlink information that is stored at the S-GW buffer, thereby reducing the potential for overflow at the S-GW buffer.
