Abstract:
A device (110) receives consecutive negative acknowledgments (NACKs) (540), measures a downlink channel quality (530) associated with the device (110), and triggers autonomous retransmission (430) when power is limited in the device (110), when the device (110) is using a minimum usable enhanced dedicated channel (E-DCH) transport format combination (ETFC), and when one of a number of consecutive NACKs (540) is greater than a predefined number, or the measured downlink channel quality (530) is less than a predefined threshold.
Abstract:
A radio node for selectively providing synchronization information for Device-to-Device, D2D, communications between devices in a wireless communications network is also provided.
Abstract:
The present invention provides a method in a base station for determining channel interference in a radio network comprising a device-to-device, D2D, capable UE and the base station serving at least one cellular UE, said method comprising: configuring the at least one cellular UE with a cellular uplink Reference Symbol, RS, related parameter; transmitting the cellular uplink RS related parameter associated with the at least one cellular UE to the D2D capable UE; and obtaining information of interference to the D2D capable UE measured by the D2D capable UE using the cellular uplink RS related parameter. The present invention also provides a corresponding method in D2D capable UE and the devices thereof. This achieves a more accurate the interference channel measurement in multi-cell and multi-antenna scenario.
Abstract:
In a radio system information is transmitted from a network node to a UE informing the UE about a dedicated pilot signal used in a combined cell when a handover of a User Equipment is performed from a first combined cell to a second combined cell.
