摘要： Systems, methods, and apparatuses for analyzing and synthesizing wireless communication signals are provided. A receiver might transform a received signal into a basis in which the transformed signal is sparse, which can reduce the complexity of joint detection by facilitating message passing algorithm (MPA) decoding. A transmitter might employ dense codewords in a first basis, which may facilitate certain signal-processing operations and may provide a transmission with a low peak-to-average-power ratio. The codewords can be designed to be sparse when transformed to a second basis. The codewords may be configured for non-orthogonal multiple access.

摘要： A network or system in which a hub or primary node may communicate with a plurality of leaf or secondary nodes. The hub node may operate or have a capacity greater than that of the leaf nodes. Accordingly, relatively inexpensive leaf nodes may be deployed to receive data carrying optical signals from, and supply data carrying optical signals to, the hub node. One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, optical splitters/combiners, and optical add/drop multiplexer, for example. Optical subcarriers may be transmitted over such connections, each carrying a data stream. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced. As the bandwidth or capacity requirements of the leaf nodes change, the number of subcarriers, and thus the amount of data provided to each node, may be changed accordingly. Each subcarrier within a dedicated group of subcarriers may carry OAM or control channel information to a corresponding leaf node, and such information may be used by the leaf node to configure the leaf node to have a desired bandwidth or capacity.

摘要： This document describes techniques for configuring beamformed wireless communication between a base station (121) and a user equipment (110) for grant-free communication using non-orthogonal multiple access (NOMA). In aspects, a base station (121) transmits downlink reference signals to a user equipment (110) using multiple transmit antenna configurations (402), configures multiple time-frequency resources for NOMA transmission by the user equipment (110) (404), and configures an association between the downlink reference signals and the time-frequency resources for the user equipment (110) (406). The base station (121) transmits the configuration of the time-frequency resources and the association between the downlink reference signals and the time-frequency resources to the user equipment (110) (408). The base station (121) receives uplink data from the user equipment (110) on one of the time-frequency resources using a receive antenna configuration, determined, at least in part, using one of the transmit antenna configurations (410).

摘要： Consistent the present disclosure, a network or system is provided in which a hub or primary node may communication with a plurality of leaf or secondary nodes. The hub node may operate or have a capacity that may be greater than that of the leaf nodes. Accordingly, relatively inexpensive leaf nodes may be deployed that receive data carrying optical signals from and supply data carrying optical signals to the hub node. One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, and optical add/drop multiplexer, for example. Consistent with an aspect of the present disclosure, optical subcarriers may be transmitted over such connections. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced. In addition, the subcarriers may be employed using multiple access techniques, such as frequency division multiplexing (FDM), code-division multiple access (CDMA), and time-division multiple access so that the primary node can communicate with a relatively large number of secondary nodes. In addition, an out-of-band control channel may be provided to carry OAM information from the primary node to the secondary nodes, as well as from the secondary nodes to the primary nodes.

摘要： Techniques for wireless communications are described. A user equipment (UE) may be configured with one or multiple transmission and reception points (TRPs). The UE may support sidelink communications, which may be referred to as vehicle-to-everything (V2X) communications systems, vehicle-to-vehicle (V2V) communications systems, and the like. The UE may provide improvements to resource determination for the sidelink communications by determining whether multiple peer UEs can be space-division multiplexed over time and frequency resources. To mitigate interference between the multiple peer UEs, the UE may transmit a power control request message to one or multiple peer UEs to adjust a transmit power level, and a receive a power control response message from the one or multiple peer UEs accepting or rejecting the transmit power level adjustment. As a result, the UE may experience efficient sidelink operations.

摘要： The present application discloses a signal sampling and recovery method and apparatus applicable to an OvXDM system, and the OvXDM system. The method includes: constructing, based on design parameters, an observation matrix Φ that is irrelevant to an original signal y, wherein the observation matrix Φ is a two-dimensional M*S matrix, S is a length of the original signal y, and M is smaller than S; compressing the original signal y based on a formula Ycs=ΦY, to obtain a M*1 compressed signal Ycs, wherein Y is a S*1 column vector that is obtained according to the original signal y; and reconstructing the compressed signal Ycs based on a predetermined algorithm, so as to recover the original signal y. The present application implements accurate recovery of the original signal at a reduced sampling rate, thereby reducing hardware requirements of the system and improving feasibility of the technical solution.
