摘要： Channel reservation in time division duplex for devices in systems involving, for example user devices and access points, may be accomplished using channel reservation request messages, such as request-to-send (RTS) messages and channel reservation grant messages, such as clear-to-send (CTS) messages. A method for channel reservation may include preparing a frame including at least one channel reservation request message and at least one channel reservation grant message. The preparing may include multiplexing the at least one channel reservation request message and the at least one channel reservation grant message at least by frequency-division multiplexing. The method may also include transmitting the frame from a first node to a second node, wherein the channel reservation request message and the channel reservation grant message relate to communications between the first node and the second node.

摘要： According to an embodiment, a method, apparatus, and computer readable medium can provide an efficient mechanism to improve data rates of nodes suffering high interference without sacrificing performance of nodes that do not need interference-free channels to communicate. A node can receive two or more RTS packets and identify the RTS packet corresponding to its own cell, as well as RTS packets belonging to interferers. Based on the interference level estimated from the RTS packets, the node can decide if the channel needs to be interference-free for the intended transmission or if the current level of interference is acceptable. According to the embodiment, there can be two or more different types of CTS packets. A node can decide which type of CTS packet to transmit based on the information, signal level, interference level, or a combination therein, of at least two RTS channels, and based on measurements performed on these RTS channels, or other channels.

摘要： A method is disclosed that includes selecting one or more terminals involved in a device-to-device communication to which interference caused by a transmission to one or more other terminals should be suppressed, and choosing a number of degrees of freedom from a predetermined number of degrees of freedom to be used to suppress interference towards the selected one or more terminals. The method also includes using the remaining degrees of freedom from the predetermined number to increase signal quality to the one or more other terminals and performing precoding based on the chosen number of degrees of freedom and the remaining degrees of freedom. The method further includes, using at least the performed precoding, transmitting information to the one or more other terminals. Apparatus and programs/program products are also disclosed.

摘要： An aspect of this invention is a definition of a set of reused channel state information reference signal (CSI-RS) resources among transmission points, which can be lower power nodes, for intra-cell coordinated multi-point (CoMP) operation. Separate CSI-RS resources are defined for each transmission point for sporadic separate measurements to be made by user equipment. The sporadic measurements may be implemented with low additional overhead, and are used for generating potentially simplified CSI feedback to an evolved NodeB that enables adapting shared channel reuse and also potentially making related channel quality indicator (CQI) compensation.
摘要翻译： 本发明的一个方面是用于小区内协调多点（CoMP）操作的传输点之间的一组重用信道状态信息参考信号（CSI-RS）资源的定义，其可以是较低功率节点。 为每个传输点定义单独的CSI-RS资源，用于由用户设备进行的零星分离测量。 零散测量可以用低附加开销来实现，并且用于向演进的节点B生成潜在的简化的CSI反馈，这使得能够适应共享信道重用并且还潜在地产生相关的信道质量指示符（CQI）补偿。

摘要： One embodiment is directed to a method, apparatus, and/or computer program for reducing interference in a local area radio system. The method may include selecting, by a first network node, time/frequency resources to transmit data, transmitting request to send (RTS) bursts to a second network node on the selected resources, and listening for clear to send (CTS) bursts. The method may further include separating received clear to send bursts, decoding the clear to send bursts received from the second network node, determining whether data is allowed to be transmitted based on the received clear to send bursts, and transmitting the data to the second network node when it is determined that the data can be transmitted. The request to send and/or clear to send bursts may be encoded with orthogonal codes when there are multiple cells in a neighborhood of the first network node and/or the second network node.
