  • Patent number: 10812955
    Abstract: Signals with unpredictable transmission properties enabling physically secure, unscheduled and interference-resistant machine-to-machine (M2M) communication are described. A physical dwell structure containing time slots and frequency channels is established, and a combination of unpredictable physical dwells, spread spectrum modulation with unpredictable spreading vectors, and unpredictable selection of intended receivers is described. These unpredictable transmission properties enable receivers to detect and extract transmissions intended for the receiver, and excise transmissions not intended for the receiver, even if they are received at much higher power levels than the intended transmissions.

  • Patent number: 10681659
    Abstract: It takes a processing time to perform a security process on a time synchronization message, thus the difference of a delay time required for the security process can be made between a time at which the time synchronization message is actually transmitted and a transmission time assigned to the time synchronization message, and therefore, the difference between the actual transmission time of the time synchronization message and the assigned transmission time needs to be reduced. In generation of a secure time synchronization message in the synchronization system according to embodiments of the present invention, most of the security processes is performed in an upper layer which is an MAC layer or a higher layer, and processes including the assignment of the transmission time and assignment of authentication information for authenticating validity of the transmission time are performed in a physical layer.

  • Patent number: 10110360
    Abstract: A recovery mechanism for robust header compression (ROHC) is disclosed for wireless communication systems. The ROHC recovery mechanism may allow a receiver and/or transmitter in the wireless systems to establish or reestablish a context of a packet transmission session when an initialization and refresh message is lost. In the ROHC recovery mechanism, upon receiving a compressed packet that is not associated with a context, a receiver sends a message to a transmitter suggesting the transmitter to transition to another mode. Upon receiving a subsequent packet transmission that is not associated with a context, the receiver sends another message indicating that a context has not been established or has been lost. The transmitter may then send the receiver necessary information to establish a context for the packet transmission session.

  • Patent number: 9999036
    Abstract: Provided are a radio terminal device, a radio base station device, and a channel signal forming method which can prevent quality degradation of the downlink resource allocation information by reducing the frequency of the zero information addition process to the downlink resource allocation information when executing communication using an uplink unit band and multiple downlink unit bands correlated to the uplink unit band. A base station includes: a PDCCH generation unit which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size.

  • Patent number: 9924221
    Abstract: Method and systems are provided for detecting and handling, by a controller device, a loss of control of a playback queue of a zone group of a media playback system. Detection of loss of control of the playback queue of the zone group may involve one or more of determining (i) that the zone group no longer exists, (ii) that a queue identifier is no longer assigned to a playback queue of the zone group, and (iii) that the controller device is no longer in communication with the media playback system, among others. Handling of the loss of control may involve one or more of (i) unsubscribing from messages relating to the zone group, (ii) ceasing to send commands to the zone group, and (iii) updating a user interface to indicate that the controller device no longer has control of the playback queue of the zone group, among others.

  • Patent number: 9898532
    Abstract: Embodiments described herein may involve inconsistent queues. An example implementation may involve a computing device receiving a message indicating a playback queue corresponding to a playback zone of a media playback system. The playback queue may include first media items queued in a first order for playback by the playback zone. The computing device determines that a playlist at the computing device is to be queued for playback in the playback queue corresponding to the playback zone, the playlist including second media items in a second order. The computing device determines that the first media items in the first order is different from the second media items in the second order, and based on the determination, causes the first media items in the playback queue to be replaced with the second media items in the playlist.
