摘要： Systems and methods are disclosed for partitioning resources into resource partitions, and informing user equipments (UEs) of the resource partitions. Knowledge of the resource partitions may assist the UEs in performing joint decoding. In one embodiment, a method performed by a UE includes receiving at least one message from each base station. The at least one message provides information indicating how resources are partitioned by the base station into a respective plurality of resource partitions. The information is used to identify respective resources for each of at least two downlink transmissions. Respective data that was transmitted on each of the at least two downlink transmissions using the respective resources is jointly decoded.

摘要： Methods, apparatuses and systems are described. A device, in the active state, receives, from a serving transmission point, a device connection identifier (DCID) associated with the device. The device, in the standby state, periodically transmits, to the same or different serving transmission point, an identifying signal that identifies the first device using the DCID, to synchronize the first device with a wireless communications network.

摘要： A system is provided for allocating downlink transmit power in a wireless multiple-input multiple-output (MIMO) system. During operation, the system identifies a set of receivers for receiving signals from one or more transmitters on a same time-frequency slot, receives channel state information (CSI) for communication channels between the identified receivers and the transmitters, and constructs a precoder based on the CSI. The system further derives a set of power-scale factors for the precoder based on a utility function associated with the identified receivers such that the power-scale factors optimize the utility function. A respective power-scale factor scales power transmitted to a corresponding receiver.

摘要： A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.
