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 guaranteeing a quality of experience (QoE) associated with data provision services in an enhanced data delivery network. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax 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 exemplary implementation, “over-the-top” voice data services may enable exchange of voice traffic with client devices in the aforementioned network. A distribution node may use a detection rule to identify received packets as voice traffic, and cause a dedicated bearer to attach to the default bearer, thereby enabling delivery of high-quality voice traffic by at least prioritizing the identified packets thereafter and sustaining the delivery even in a congested network environment, and improving the quality of service (QoS) and QoE for the user(s).

Abstract: User equipment receives first connection priority information. In accordance with the first connection priority information, the mobile communication device establishes a first wireless communication link between the user equipment and a first wireless network to communicate first communications. A controller/management resource provides notification of second connection priority information to be used instead of the first connection priority information. In response to detecting a trigger event in which the user equipment is operated to communicate second communications, the user equipment uses the second connection priority information as a replacement to the first connection priority information to establish a second wireless communication link connecting the user equipment to the second network instead of the first network.

Abstract: A first wireless communications device including a transmitter, such as a base station or UE, identifies a first traffic flow, e.g., a TCP packet flow, for which end to end packet retransmission is supported. The first wireless communications device transmits an explicit indication to a second wireless communications device to skip Hybrid Automatic Repeat Request (HARQ) feedback for data, corresponding to the first traffic flow, said data being transmitted to the second wireless communications device. The explicit indication to skip HARQ feedback for data is, e.g., one of: a HARQ Off Indicator in a Downlink Control Information (DCI) Scheduling message, a Semi-Persistent Scheduling HARQ Off Indicator, or a AUL HARQ Off Indicator. HARQ suppression is applied for the first traffic flow at a radio link layer and/or MAC layer.

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: Architectures, methods and apparatus for providing data services (including enhanced ultra-high data rate services and IoT data services) which leverage existing managed network (e.g., cable network) infrastructure, while also providing support and in some cases utilizing the 3GPP requisite NSA functionality. Also disclosed are the ability to control nodes within the network via embedded control channels, some of which “repurpose” requisite 3GPP NSA infrastructure such as LTE anchor channels. In one variant, the premises devices include RF-enabled receivers (enhanced consumer premises equipment, or CPEe) configured to receive (and transmit) OFDM waveforms via a coaxial cable drop to the premises. In another apect of the disclosure, methods and apparatus for use of one or more required NSA LTE channels for transmission of IoT user data (and control/management data) to one or more premises devices are provided.

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.
