Aspects described herein relate to selecting a base representation for an advance offset of a shift register sequence, generating the shift register sequence corresponding to the advance offset based at least in part on the base representation, and processing a signal based at least in part on the shift register sequence.

Configuring arbitrary jumps in a linear feedback shift register in wireless communications

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.

Methods and apparatus for employing different capabilities for different duplexing modes

Systems and methods for avoiding conflict in a wireless mobile display digital interface (WMDDI) environment including both host and client devices. In one aspect, the presently claimed invention includes a system and/or method that is configured for broadcasting a first multicast MAC address by a first host to at least one first client in a predetermined geographic area and broadcasting the first multicast MAC address by a second host to at least one second client in the predetermined geographic area. The system and/or method can be further configured for determining a priority between the first host and the second host when the second host receives multicast packets transmitted by the first host and changing to a second multicast MAC address by a least priority host of the first host and the second host.

Embodiments are described in connection with transferring data traditionally communicated through a wired link over a high-speed wireless link. The disclosed embodiments provide the wired and/or wireless data communication with minimal changes on the existing wired architecture. According to an embodiment is an apparatus for communicating wirelessly over a traditional wired link. The apparatus includes a transmitter comprising a host and a first portion of a client connected by a wired link and a receiver comprising a second portion of the client. According to some embodiments, the apparatus can include a query module that determines an operation rate based in part on a rate supported by a medium access control and a retransmission statistic and an assigner module that assigns a communication to a wired protocol or a wireless protocol.

Wireless architecture for a traditional wire-based protocol

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.

Wireless architecture for traditional wire based protocol

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.

Interference mitigation mechanism to enable spatial reuse in UWB networks

A piconet in which at least one master communication station and at least one slave communication station are self-designated implements a successor hierarchy. A wireless device (DEV) functioning as a piconet controller (PNC) poll a plurality of DEVs to obtain data concerning other DEVs in range of the respective polled DEVs. Data concerning stations in range of the respective polled stations is received and at least one successor DEV is selected as a successor PNC based on the received data concerning stations in range of the respective polled DEVs. The selection of the successor DEVs is communicated to the successor DEVs. This provides for continuity of communication.

Removal of ambiguities in forming new piconet controller (PNC) when the current PNC controller is suddenly unavailable

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.

Reservation based MAC protocol

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.
