摘要： Frame structures and signaling arrangements for interference aware scheduling may be applicable to a local area radio system to complement existing wide area cellular systems, like GSM/UMTS/HSPA/LTE. In certain embodiments a method is provided including preparing a frame for transmission in a wireless communication system. The method can also include incorporating an interference report into the frame. The interference report is directly associated with a corresponding resource. The method can further include transmitting the interference report within the frame in the wireless communication system.

摘要： Systems and methods for providing an efficient mechanism for transmitting interference vectors to communications terminals, such as user equipments (UEs), in an over the air radio telecommunications network with spatially multiplexed multiple user multiple input multiple output (MU-MIMO) capability. A new pre-coding information downlink channel is defined. Messages containing semi-persistent interference vector information for MU-MIMO user equipment are defined and transmitted over the new channel in a manner that allows infrequent transmission and efficient use of resources. Using the interference vectors and applying inter-user interference adaptation to received messages, the UEs may receive spatially multiplexed MIMO transmissions and actively remove inter-user interference after reception of the messages. Compression of the pre-coding vector information transmitted over the pre-coding information channel may result in additional increases in efficiency in the system.

摘要： An apparatus for providing coordination of device to device communication may include a processor. The processor is configured to communicate a request for a resource allocation to a network communication node (300). The resource allocation is related to resources usable for device to device communication between a first terminal communicating the request and a second terminal. The processor is further configured to receive a resource allocation including an amount and duration of resources to be used for the device to device communication in response to the request (310), and utilize the resource allocation for device to device communication with the second terminal (320).
