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: Premises apparatus and methods for providing aggregated high-bandwidth, low-latency, data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3 GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Wideband amplifier apparatus are used to support delivery of the sub-bands to CPE within the network.

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: Apparatus and methods for unified high-bandwidth, low-latency data services provided with enhanced user mobility. 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. Premises devices are used to provide the 5G-based services to users at a given premises and thereabouts. In another variant, local area (e.g., “pole mounted”) radio devices are used to provide supplemental RF coverage, including during mobility scenarios. The 5G-capable network enables uninterrupted and “seamless” exchange of data at a client device by utilizing a common waveform protocol (e.g., 3GPP-based) at a premises device and an external radio device to communicate with a client device at different locations and times while the device is moving between inside and outside the premises.

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: Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.

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: Both wireless communication and communications via a cable modem are supported between a network node and a customer premises. Alternative communications links provide redundancy and the possibility to take advantage of the different types of links capacity to provide a level of service that would not be possible using a single communications link to a customer premises. In various embodiments a network node, such as a cable network node hubsite, has an optical connection to the Internet or another communications network and provides network access to one or a plurality of customer premises. The network node includes a wireless access point, e.g., pole mounted base station, as well as one or more cable modem interfaces to thereby allow for both wireless and cable modem based communications. This allows for packets of different applications to traverse different links and/or to switch between links in the event of maintenance or reliability issues.
