Abstract: Apparatus and methods for improving throughput and reliability in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device buffer management that mitigate buffer overflow within the device due to overscheduling, such as from different networks with which the device is connected simultaneously. In one variant, a 3GPP-based signaling architecture from wireless device to the multiple networks is provided to enable user device-controlled management buffer overflow. In another variant, potentially buffer-demanding (e.g., HARQ) process management and prioritization rules are defined to avoid buffer overflow. In other variant, buffer size computation is provided considering the number of networks to which the wireless user device can connect.

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 operating wireless devices using unlicensed frequency ranges with minimal transmission interruptions. In one embodiment, the apparatus and methods provide a mechanism for redirecting idle or inactive wireless devices to different frequencies in response to interference detection such as by 5 GHz-band radar. In one variant, the present disclosure provides methods and apparatus for allowing user device (UEs) using 5G NR-U spectrum to continue to operate upon radar detection by successfully switching the UEs to one or more frequencies that are free of radar operation. In one variant, a gNB controlling the UEs informs the AMF (access and mobility function) of a radar detection event, and the AMF initiates a paging towards idle UEs in order to allow the gNB to move the UEs to a frequency without radar operations. In another variant, a gNB switches its UEs to a different frequency without relying on the AMF.

Abstract: The present invention relates to methods and apparatus for providing backhaul wireless services using a plurality of different Radio Access Technologies. An exemplary method embodiment includes the steps of: determining a set of routes for the communication of data from a first wireless base station to a destination wireless base station over wireless backhaul communications links, the first wireless base station being an Integrated Access and Backhaul donor, receiving data of a first flow at the first wireless base station for communication to a first wireless user equipment device attached to the destination wireless base station; and selecting, at the first wireless base station, one or more of the routes of the set of routes from the first wireless base station to the destination wireless base station, the selection being based on multi-Radio Access Technology (multi-RAT) capability of wireless base stations of which a route is comprised.

Abstract: In a further aspect, a method of operating a wireless access node connected to one or more wireless user devices is disclosed. In one embodiment, the wireless access node is connected to the one or more wireless user devices through a first frequency channel located in an unlicensed spectrum, and the wireless access node is a 3GPP NR gNB including an enhanced central unit (CUe) and/or at least one enhanced distributed unit (DUe) connected to the central unit. In one variant, the method includes: performing interference (e.g., radar) detection in the first frequency channel using the wireless access node; based on detection of interference, selecting at least one second frequency; and sending instructions to the one or more wireless user devices from the wireless access node, the instructions configured to make the one or more wireless user devices switch to the at least one second frequency. In one implementation, the at least one second frequency includes a plurality of different frequencies.

Abstract: Methods and apparatus for supporting use of multiple bandwidth parts, some of which are in a dormant state from the perspective of a User Equipment device (UE) are described. In various embodiments a multi-cell grant is supported in which a UE can be, and sometimes is, granted resources corresponding of an active bandwidth part (BWP) corresponding to a cell which is active from the UE's perspective and a BWP of a dormant cell with the multi-cell grant being transmitted to the UE on the active BWP of the active cell. Various features relate to timing determination operations used to determine downlink and/or uplink timing to be used for bandwidth portions corresponding to a dormant cell. In some embodiments a UE PRACH signal transmission on a bandwidth part of a dormant cell can be triggered by a control signal sent on a bandwidth part of an active cell.

Abstract: According to one configuration, a system includes a mobile communication device operated in a network environment. The mobile communication device can be one of multiple mobile communication devices in the network environment. To request establishing a wireless link, the mobile communication device receives a notification of an allocation of wireless channel resources. Via the allocated wireless channel resources, over a shared access channel, the first mobile communication device communicates a wireless connection request to a wireless base station. In one example configuration, the wireless request communicated over the allocated wireless channels includes: i) a first wireless communication including a preamble (such as PRACH message), and ii) a second wireless communication (such as a PUSCH message) including information for establishing a wireless communication link.

Abstract: According to one configuration, a wireless network environment includes a first wireless network and a second wireless network. A mobile communication device in the wireless network environment receives first paging notifications directed to the mobile communication device from a first wireless base station such as operated by a first wireless network service provider. The mobile communication device receives second paging notifications directed to the mobile communication device from a second wireless base station such as operated by a second wireless network service provider. The wireless network environment provides improved paging over conventional techniques.

Abstract: According to one configuration, while the user equipment is wirelessly connected to a first wireless base station over a first wireless communication link, a communication management resource in the user equipment receives input (such as a request) to tune-away the user equipment to a second wireless base station providing corresponding wireless services. To facilitate the temporary tune-away to the second wireless network, the communication management resource of the user equipment generates timing information associated with the switchover. In furtherance of the switchover (temporary tune-away) to the second wireless base station, the communication management resource of the user equipment transmits the timing information in a wireless communication over the first wireless communication link to the first wireless base station.
