摘要： Aspects describe service discovery of wireless MDDI client-capable devices though interaction with an underlying bearer protocol. Service discovery can be performed when the underlying layer supports multicasting, when the underlying layer is wiMedia UWB MAC and/or UDP/IP. Service discovery can be initiated by a w-MDDI sender and/or a w-MDDI receiver. An optional mutual security association procedure can be conducted if both devices support security and security is necessary.

摘要： Mechanism to mitigate signal interference in ultra wide band (UWB) networks based on spatial reuse of the signal spectrum. Efficient media access control (MAC) in wireless networks is challenging because wireless devices may be affected by signal interference during spatial multiplexing. Wireless ad-hop (multi-hop) networks exploit the limited system bandwidth available via spatial reuse to enhance aggregate throughput. Spatial reuse allows concurrent data exchanges, resulting in higher throughputs.
摘要翻译： 基于信号频谱的空间复用来减轻超宽带（UWB）网络信号干扰的机制。 无线网络中的高效媒体访问控制（MAC）是具有挑战性的，因为无线设备可能在空间复用期间受到信号干扰的影响。 无线广播（多跳）网络通过空间重用利用可用的有限系统带宽来提高聚合吞吐量。 空间重用允许并发数据交换，从而产生更高的吞吐量。

摘要： Embodiments describe scheduling communication in an ad hoc multihop network. Included is a reservation based Medium Access Control (MAC) protocol that has resources scheduled along the path from source to destination. Admission control is performed on a per-hop basis and a decision is made, in a distributed manner, if enough resources exist along the multihop path to admit a new communication.

摘要： A method, system and computer program product for a wireless mobile display digital interface (WMDDI) association procedure that allows establishing and joining more than one multicast group to facilitate the interoperability of multiple client devices based on host and client capabilities. The protocol provides for the exchange and update of capabilities and multicast addresses for layered multicast transmission applications. The system is used for interoperating devices with different capabilities and provides for efficient transmissions by using different multicast addresses mapped to different layers of a bitstream. The protocol adapts to changes in capabilities, in joining/releasing of multicast addresses and in link quality.

摘要： Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.
