Resilient data communications with physical layer link aggregation, extended failure detection and load balancing
11558285 · 2023-01-17 · ·

Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

System and Method for Carrier Aggregation for Wireless Local Area Networks
20180007579 · 2018-01-04 ·

Embodiments are provided herein for improving carrier aggregation for wireless networks. A plurality of bandwidth channels are assigned to a basic service set (BSS) for transmissions. Specifically, the bandwidth channels are divided into multiple channel segments corresponding to multiple primary or alternate primary channels. A channel segment possibly further includes one or more additional secondary channels. The locations of the primary or alternate primary channels that correspond to the channel segments of the BSS are then broadcasted in the network. When a station or AP receives this BSS information, it searches for an available primary or alternate primary channel of the BSS to begin transmission. Upon detecting an available primary channel or alternate primary channel that is not used for another transmission, the station or AP transmits data on the channel segment corresponding to the detected primary or alternate primary channel.

MANAGEMENT OF EMERGENCY ALERT WAKE UP BITS
20180014171 · 2018-01-11 ·

Systems and methods are described, which prompt a UE that is receiving at least a physical layer signal from a broadcasting station to look for a new emergency alert. In embodiments, the UE renders content from the broadcasting station based on information received in transmitted physical layer frames. Included within a physical layer frame are bits, such as, ea_wake_up_bits. If the state change of the ea_wake_up_bits indicates that a new emergency message, referencing a new emergency alert, is being transmitted within the physical layer frame, the LTE locates the new emergency message within the physical layer frame and acts on the emergency message if it is applicable to the station to which the UE is tuned. If the emergency message is applicable, the UE acts on the emergency message by using information in the emergency message to locate and render the emergency alert. The emergency message may point to an EAS present on a linear TV service.

Probabilistic amplitude shaping

This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve a desired amplitude distribution. Some implementations more specifically relate to performing an encoding operation to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some implementations of the non-uniform distribution, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. Some implementations enable the tracking of MPDU boundaries to facilitate successful decoding by a receiving device. Additionally or alternatively, some implementations enable the determination of a packet length after performing the amplitude shaping, which enables a transmitting device to determine the number of padding bits to add to the payload and to signal the packet length to a receiving device so that the receiving device may determine the duration of the packet.
