Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink.

Abstract: This disclosure is generally directed to an RFID system that includes a hybrid RFID tag offering a functionality of a passive RFID tag and an active RFID tag. When operating as a passive RFID tag, an RF signal received from an RFID reader is harvested to produce a DC voltage for powering the hybrid RFID tag.

A controller chip in the hybrid RFID tag can execute some RFID functions at this time, thereby speeding up a response to the RFID reader. The capacitor is then charged at a fast-charging rate for storing a reserve charge. The hybrid RFID tag can subsequently use the reserve charge to operate as an active RFID tag without waiting for an RF signal from the RFID reader.

Abstract: A resource-efficient modulation scheme includes both conventional and zero-amplitude states. The conventional states in 5G/6G are amplitude- or phase-modulated, or both, whereas the zero-amplitude states have zero or substantially zero amplitude. By including modulation states with zero amplitude in the modulation scheme, transmitters can transmit a message more compactly, and using less time or bandwidth, and with a substantial decrease in emitted energy. For example, in a phase-modulation scheme such as BPSK or QPSK, a zero state represents an additional modulation state with zero transmitted amplitude. In a modulation scheme with I and Q branches in quadrature, each branch is separately amplitude modulated, plus additional states with zero amplitude in one or both branches, for different effects. For example, 16QAM with nine additional zero-amplitude states totals 25 available modulation states, resulting in 36% reduction in message size and 44% reduction in transmitted energy.

Abstract: Techniques for leveraging MLD capabilities at edge nodes of network fabrics to receive SNMAs from silent hosts, and creating unicast addresses from the SNMAs for the silent nodes that are used as secondary matches in a network overlay if primary unicast address lookups fail. The edge nodes described herein may act as snoopers of MLD reports in order to identify the SNMAs of the silent hosts. The edge nodes then forge unicast addresses for the silent hosts that match with the least three bytes of the SNMAs. The forged unicast addresses are presented as unicast MAC/IP mappings in the fabric overlay. In situations where a primary IP address lookup fails, the look-up device performs a secondary lookup for a mapped address that has the last three bytes of the IP address. If a mapping is found, the lookup is sent as a unicast message to the matching MAC address.

Abstract: Systems and methods for providing a shared augmented reality environment are provided. In particular, the latency of communication is reduced by using a peer-to-peer protocol to determine where to send datagrams. Datagrams describe actions that occur within the shared augmented reality environment, and the processing of datagrams is split between an intermediary node of a communications network (e.g., a cell tower) and a server. As a result, the intermediary node may provide updates to a local state of a client device when a datagram is labelled peer-to-peer, and otherwise provides updates to the master state on the server. This may reduce the latency of communication and allow users of the location-based parallel reality game to see actions occur more quickly in the shared augmented reality environment.

The decoding spectrum modulation may effectively avoid a ringing effect. The method and system can improve the data compression efficiency, and improve transmission efficiency, while improving definition of the decompressed data.
