20140079218 | System and Method for Device-to-Device (D2D) Assisted Dynamic Traffic Control for Cellular Networks - Method and apparatus are provided for offloading data from a cellular network via a secondary network. The offloaded data may be transported over a connection existing independently from the cellular network, such as a direct device-to-device (D2D) or direct mobile communications (DMC) link. The connection may be established between a first peer mobile device and a benefactor peer mobile device, and the benefactor peer mobile device may relay the data to/from a backhaul network via the secondary network. The benefactor peer mobile device may receive compensation for offloading the traffic, and may compete with one or more candidate benefactor devices for the task of offloading the data. The offloaded data may be uplink data originating from the beneficiary peer mobile, or downlink data destined for the beneficiary peer mobile. | 03-20-2014 |
20140301301 | Device, Network, and Method for Utilizing a Downlink Discovery Reference Signal - User equipments can achieve quick channel synchronization when establishing a connection to base stations transitioning from a sleep mode to an active mode by using discovery resource signal (DRS) processing results and cell reference signal (CRS) processing results to establish channel synchronization with a CRS antenna port. More specifically, the user equipment may be notified that the CRS antenna port and DRS antenna port are quasi-co-located (QCL), and then use DRS processing results in conjunction with CRS processing results to obtain faster channel synchronization with a CRS antenna port. This may be particularly beneficial when the target BS is transitioned from a sleep mode to an active mode in order to accept a handover of the user equipment. | 10-09-2014 |
20140314000 | Systems and Methods for Adaptive Transmissions in Wireless Network - A method for cell adaptation includes receiving, by a user equipment (UE), one or more transmission parameters for a transition reference signal (TRS). One or more cells is transitioned between a reduced activity mode and an active transmission and reception mode in accordance with the TRS. The method further includes the UE determining whether or not to transmit the TRS in accordance with one or more TRS transmission criteria, and the UE transmitting the TRS in accordance with the one or more transmission parameters. | 10-23-2014 |
20140334320 | Systems and Methods for Network Adaptation Support in Wireless Network - Embodiments are provided for implementing network adaptation schemes, including small cell on/off adaptation and transmission power control. In an embodiment method for supporting network adaptation, a network component receives a discovery reference signal (DRS) from a network controller that is in a switch-off transmission mode. The network component then performs measurements according to the DRS, and reports the measurements to a network associated with the network controller. In return, the network component receives a radio resource control (RRC) signaling from the network. The RRC signaling includes configuration information allowing a connection between the network component and the network controller. The network component then connects with the network controller in accordance with the configuration information. | 11-13-2014 |
