    Abstract: PROBLEM TO BE SOLVED: To provide a wireless media access control which supports asynchronous communication.SOLUTION: A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. A monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may originally have been transmitted during the scheduled transmission period. A wireless media access control supports asynchronous communication and overlapping transmissions. A wireless node may determine whether to request or schedule a transmission on the basis of control messages it receives from neighboring nodes. Data and control information is transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

    Abstract translation: 要解决的问题：提供支持异步通信的无线媒体访问控制。 解决方案：调度传输可以被划分成几个段，使得发射节点可以在段之间接收和发送控制消息。 在调度的传输周期之后定义监视周期，以使得发送节点能够获取原本在调度的传输周期期间已被发送的控制信息。 无线媒体访问控制支持异步通信和重叠传输。 无线节点可以基于从相邻节点接收的控制消息来确定是否请求或调度传输。 数据和控制信息通过不同的频分多路复用通道传输，以实现数据和控制信息的并发传输。 版权所有（C）2013，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To achieve the inter-node fairness of wireless communication using resource utilization messages (RUMs), in accordance with various aspects.SOLUTION: A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

    Abstract: PROBLEM TO BE SOLVED: To realize efficient resource negotiation by determining a transmission delay threshold, at which the resource negotiation information becomes invalid, between base stations that exchange the information, and by discarding the information transmitted with delays beyond the threshold.SOLUTION: One or more resource negotiation messages are received at a base station (S402). The resource negotiation messages received with delays beyond a determined delay threshold are discarded (S404). Using only the non-discarded resource negotiation messages, resources are allocated with a distributed resource negotiation algorithm (S406).

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methods that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell-specific reference signals (CRS), to improve audibility thereof for applications such as trilateration and/or the like.SOLUTION: PRSs can be transmitted in designated or selected positioning subframes. Resource elements within the positioning subframe can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, portions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

    Abstract: PROBLEM TO BE SOLVED: To improve network interference management for wireless networks.SOLUTION: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

    Abstract translation: 要解决的问题：改善无线网络的网络干扰管理。 解决方案：在某些情况下，例如在确定节点未被授权用于访问节点处的数据访问时，可以与接入节点建立仅信令访问。 在访问节点处未被授权用于数据访问的节点仍然可以由接入节点通过使用仅信令接入进行寻呼。 以这种方式，接入节点的传输可能不干扰节点处的页面的接收。 可以选择第一节点来提供寻呼，而在某些情况下例如在确定第二节点提供比第一节点更理想的服务时，第二节点被选择用于接入。 版权所有（C）2013，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method for supporting asynchronous communication and overlapping transmissions in an ad hoc network.SOLUTION: A wireless node determines whether or not a transmission should be requested or scheduled based on control messages received from neighboring nodes. A scheduled transmission is divided into several segments so that a transmitting node can receive and transmit the control messages between segments. A monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. Data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.
