Abstract: Methods and apparatus for facilitating the use of a plurality of antenna beams for communications purposes are described. In at least some embodiments beam priority information is periodically exchanged. Multiple timers are used to ensure beam information is exchanged at intervals intended to facilitate reliable beam synchronization and to control switching to one or more alternative beams in a predictable manner in the event beam change information or beam synchronization information is lost. In some but not all embodiments a wideband beam is used to communicate beam synchronization information when synchronization using narrower beams used for normal data communication is lost.

Abstract: Apparatus and methods for parsing data traffic into queues for efficient routing and prioritization. In one embodiment, methods and apparatus for backhauling small cell data traffic using existing cable network infrastructure using DOCSIS Low Latency queue capabilities are provided. A data traffic classifier may use a two-stages sorting algorithm, including a first stage classification using IP address information and a second stage classification using differentiated services code point (DSCP) value information. In one implementation, the DSCP values of the data traffic are set using QoS Flow Identification (QFI) values.

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.

Abstract: Radio Link Control ACK/NACK is conditionally suppressed. A first wireless communications device including a radio transmitter identifies a first packet flow for which end to end packet retransmission is supported. The first wireless communications device identifies a Packet Data Convergence Protocol (PDCP) packet corresponding to Radio Link Control Acknowledged Mode (RLC AM), said identified packet being included in the identified first packet flow. The first wireless communications device generates an Acknowledged Mode Protocol Data Unit (AM PDU) including a No RLC ACK Required (NRAR) indicator set to indicate RLC ACK is not required, and the radio transmitter in the first wireless communications device transmits the AM PDU, e.g., an AMD PDU, to a second wireless communications device. The second wireless communications device receives the transmitted AM PDU, recovers the NRAR indicator value, and based on the communicated value of the NRAR indicator, determines to suppress RLC ACK/NACK.

Abstract: A first communications device including a transmitter identifies a packet flow for which end to end packet retransmission is supported. The first wireless communications device transmits an explicit indication in a downlink message to a second wireless communications device, to skip Hybrid Automatic Repeat Request (HARQ) feedback for data, corresponding to the first packet flow, said data being directed to the second wireless communications device. In some embodiments, said explicit indication to skip Hybrid Automatic Repeat Request (HARQ) feedback for data is a predetermined value in a predetermined field of a downlink control information (DCI) scheduling message. In some embodiments, the predetermined field is a PDSCH-to-HARQ feedback timing indicator field. HARQ suppression is applied for the first packet flow at a radio link layer and/or MAC layer, e.g., by the second communications device in response to the predetermined value indicating HARQ suppression being recovered from the predetermined field.

Abstract: A first communications device including a transmitter, such as a base station or UE, identifies a first packet flow for which end to end packet retransmission is supported. The first communications device assigns said first packet flow to a Hybrid Automatic Repeat Request (HARQ) process which does not require generation of acknowledgements (ACKs) or negative acknowledgements (NAKs) from a device receiving data corresponding to said first packet flow; and transmits data corresponding to said first packet flow to a second communications device. In some embodiments, the HARQ process to which the first packet flow is assigned is a dedicated HARQ suppression process. In some embodiments, the HARQ process to which the first packet flow is assigned is a HARQ process which has been temporarily designated as a HARQ suppression process. HARQ suppression is applied for the first packet flow at a radio link layer and/or MAC layer.

Abstract: A base station in a first wireless network provides first wireless connectivity to user equipment operated by a subscriber. The first wireless network supports first wireless communications such as non-voice communications. A network management resource receives configuration information assigned to the subscriber operating the user equipment. The configuration information indicates that the subscriber is assigned use of a second wireless network that provides support of second wireless communications (such as voice communications). In response to detecting a trigger event (such as a voice call) indicating a need to switch to use of the second wireless network, the network management resource initiates termination of the first wireless connectivity and establishment of second wireless connectivity between the user equipment and a base station in the second wireless network.

Abstract: An antenna overlay system includes antenna hardware, a communication link, and electronic circuitry disposed on a substrate. The communication link couples the electronic circuitry to the antenna hardware. During operation, the electronic circuitry in communication with the antenna hardware is operable to control transmission and reception of wireless signals in a wireless region. An adhesive layer disposed on a surface of the substrate couples the substrate to an object such as a window. In one arrangement, the window is a low-E glass windowpane that substantially attenuates wireless signals from being received by communication equipment in a building in which the windowpane is installed. The antenna overlay system provides enhanced RF signal reception and transmission.
