Abstract: Apparatus and methods for interworking a user device in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given user device (e.g., a mobile 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs), such as a macro network and micro network. In one implementation, the UE contains multiple SIM cards to enable connection to different networks simultaneously. Accordingly, the UE can roam between two different networks seamlessly, regardless of whether the operators of each are independent or the same operator. Enhanced network capability as described herein advantageously allows for interworking between the macro and micro (e.g., small-cell) layers of the system without complicated network configuration requirements between the two operating networks as required under the prior art.

Abstract: A base station generates, e.g., based on current UE and current system information, a UE specific paging priority list for an idle or inactive mode UE identifying a set of (small cell base) stations which are to be used to subsequently page the UE. The base station communicates the paging priority list to the UE in a radio resource control release message. In some embodiments, the release message further conveys information indicating a maximum paging monitoring duration and/or a maximum number of paging cells to be monitored. The UE receives the release message and transitions into idle or inactive mode. The UE uses the communicated information to perform efficient paging, identifying which small cells are potential sources of a paging signal, and determine how long to monitor for a paging signal.

Abstract: Apparatus and methods for multi-carrier or multi-band utilization in an unlicensed wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which provide enhanced bandwidth capability to 5G NR-U entities such as gNodeB and UE devices across two heterogeneous unlicensed bands having different medium access mechanism and protocols. In one variant, LBT (listen before talk) protocols are used to detect the presence or absence of users within the respective bands of interest. When two or more unoccupied carriers or bands are identified, aggregated operation is used ti enhance the downlink/uplink (DL/UL) transmission bandwidth for the device(s).

Abstract: Efficient paging in a communications system including macro and small cell base stations is described. A macro cell base station receives, from a network node, a request to page a UE and determines a set of base stations including one or more small cell base stations, which are to attempt to page the UE. The macro cell base station communicates the paging request to the selected one or more small cell base stations. A small cell base station, using unlicensed spectrum, may fail in its paging attempt due to current unavailibity of the unlicensed spectrum (LBT fails to clear) resulting in no paging signal transmitted; the reason for failure is communicated from the small cell base station to the macro cell base station via a paging response message. The macro cell base station in turn communicates a paging response message to the network node communicating the reason for failure.

Abstract: A base station schedules a user equipment (UE) for uplink air link resources, e.g., unlicensed spectrum PUSCH resources, corresponding to one or more slots and, in some embodiments, at least one mini-slot. There may be, and sometimes are gaps between two scheduled slots and/or between a scheduled slot and a scheduled mini-slot. Different uplink air link resources corresponding to a schedule slot or mini-slot may, and sometimes do, use different set of frequencies. The base station generates and sends to the UE a single UL grant which grants uplink air link resources corresponding to the composite of resource allocations corresponding to the one or more slots and, in some embodiments, at least one mini-slot. The single UL grant may, and sometimes does, communicates gap information and frequency information.

Abstract: Apparatus and methods for providing an enriched content services over a network. In one embodiment, the exemplary apparatus and methods leverage extant high-bandwidth capabilities of a managed network for delivering content downstream, as well as standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) for uploading content. In one embodiment, the exemplary apparatus and methods are implemented to synchronize content delivered of extant HFC architectures and DOCSIS protocols with user-generated or other content uploaded to a network entity (e.g., server apparatus) via an IP connection established utilized 5G NR services. Additional features include, among other, enhancements which enable user participation individually, or with other subscribers, in live or recorded content-based activities (such as e.g., auctioning, broadcasting, interactive commentary/gaming, exercising, etc.).

Abstract: Methods and apparatus for efficient paging in a communications system using unlicensed spectrum are described. A base station, which uses unlicensed spectrum, receives a paging request message from a network node and performs paging operations attempting to page the UE. The paging attempt may fail due to the base station being unable to transmit a paging signal to the UE because the unlicensed spectrum is currently unavailable or because the UE did not respond to a transmitted page. The base station generates and transmits a paging failure response message including a failure cause code indicating the reason that the paging attempt failed. The network node receives the paging failure response message, recovers the failure cause code, and implements a paging escalation strategy as a function of the recovered failure cause code.

Abstract: Methods and apparatus for managing system information message transmission in a distribution network (e.g., a wireless network such as one compliant with 3GPP 5G NR-U). In one embodiment, transmission of multiple SI (System Information) messages with overlapping SI-windows is enabled but with no soft-combining support. In another embodiment, transmission of multiple SI-messages with overlapping SI-windows is enabled with soft-combining support. In yet another embodiment, aperiodic OSI transmission is enabled. Moreover, the present disclosure provides mechanisms for notifying UE of an SI change.
