  • Patent number: 11026004
    Abstract: Apparatus and methods for unified high-bandwidth, low-latency data services. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coaxial infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one variant, parallel MIMO data streams supported by 3GPP 5G NR are shifted in frequency before being injected into the single coaxial cable feeder, so that frequency diversity (instead of spatial diversity) is leveraged to achieve the maximum total carrier bandwidth that 3GPP 5G NR chipsets. Intermediate Frequencies (IF) are transmitted over the media in one implementation, (i.e., instead of higher frequencies), and block-conversion to RF carrier frequency is employed subsequently in the enhanced consumer premises equipment (CPEe) for 3GPP band-compliant interoperability with the 3GPP 5G NR chipset in the CPEe.

In an embodiment, a transmission point (TP) receives from a UE a packet encoded using a MCS, and detects a condition associated with uplink measurements or other non-link based condition of the UE. The TP then initiates an upgrade or a downgrade of the MCS in accordance with the condition, and signals the UE indicating a second MCS as a result. The UE thus sends a second packet encoded using the second MCS.

  • Patent number: 10841142
    Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a reference signal in a wireless communication system. In the method, in order to dynamically switch an uplink (UL) Demodulation-Reference Signal (DM-RS) according to the communication environment, such as CoMP and MU-MIMO, a parameter set for generation of a reference signal sequence is configured to include a Virtual Cell Identifier (VCID) parameter configured by information of a total of 9 bits and a cyclic shift hopping initial value parameter initCSH, which is 9-bit information representing one integer value among 510 integer values. Therefore, it may be possible to achieve dynamic transmission or reception of a reference signal and channel estimation through the dynamic transmission or reception of the reference signal even when the communication environment dynamically changes as in a Cooperative Multiple Point transmission and reception (CoMP) scenario.

  • Patent number: 10841205
    Abstract: A client and a server communicate over multiple wireless access paths each using a different wireless network. A method performed at the server comprises receiving at the server a signal from the client via one of multiple wireless access paths, the signal comprising a transport layer portion including a transport layer identifier, the transport layer identifier providing an indication of a wireless access path, a network layer portion, and a data portion, determining from the transport layer identifier, a destination of at least a subset of the signals from the wireless access path indicated by the transport layer identifier, and routing the signal to the destination. If a flow is diverted to travel via a different route, then there must be some mechanism to ensure that the signal arrives at its intended destination. Preferably, a Multi-path Transport Control Protocol (MPTCP) is used as the transport layer protocol.

  • Patent number: 10841767
    Abstract: Concepts and technologies disclosed herein are directed to an enhanced data download mechanism for power constrained Internet of Things (“IoT”) devices. An IoT file share server can receive an update file from an IoT application server. The IoT file share server can calculate a file chunk size based upon a device type of the IoT device and a file size of the update file. The file chunk size can be calculated such that each file chunk of a plurality of file chunks is downloadable to the IoT device in a single awake period of the IoT device. The IoT file share server can partition the update file into a plurality of file chunks to be sent to the IoT device, each of which can include a portion of the update file, and the portion can be of the file chunk size.

  • Patent number: 10826669
    Abstract: It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (?, ?) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and ? is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.
