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: 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 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 network control device, e.g., a gNB, receives a message from a communications device, e.g. a UE, indicating that the communications device is experiencing an in-device coexistence (IDC) problem, e.g. in the 52.6 GHz-71 GHz frequency range with respect to NR-U and WiGig. The message is one of: i) an IDC assistance message indicating that the victim system is Wi-Gig or ii) an antenna panel switch message requesting that the network control device instruct the communications device to change the antenna panel that it uses for uplink NR signaling. The network control device generates and sends a response message to the communications device including: a selected new frequency to be used by the communications device for uplink NR signaling or a selected different antenna panel to be used by the communications device for uplink NR signaling. The communications device implements the change reducing or avoiding the IDC problem.

Abstract: Methods and/or apparatus for reducing or avoiding (IDC) in-device coexistence problems in devices which support multiple communications protocols, e.g., WiFi and LTE, are described. In various embodiments a WiFi AP can request or require devices, e.g., STAs to report IDC information pertinent to the individual device. This is done by sending one or more trigger frames, e.g., as part of a multicast or unicast operation. Alternatively, devices can voluntarily report IDC information. The AP, e.g., WiFi AP, takes the IDC information it receives, e.g., from multiple devices, e.g., STAs, into account when scheduling UL resources to be used by the wireless devices. By taking into consideration the IDC information provided by STAs, IDC conflicts can be avoid even though a WiFi AP is scheduling resources for WiFi communication in devices which are also using resources for another communications standard, e.g., LTE, over which the AP does not have control.

Abstract: In various embodiments an explicit congestion feedback capabilities indication, e.g., information indicating a UE's support or lack of support for low latency, low loss and scalable throughput services (L4S), is communicated in a message sent from a UE to device in a network core. In some embodiments the communicated UE capability information provides information about the capability of the UE sending the message to support the use of feedback (e.g., congestion feedback) for scalable throughput services (e.g., (L4S services) or other explicit congestion notification (ECN) services which use congestion feedback for encoding and/or data rate control). In some embodiments the message or messages communicating the UE capability information include a PDU Session Establishment Request message, a PDU Session Modification Request message, and/or a Registration Request message.

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.

Abstract: Methods and apparatus for supporting wireless medium sharing in wireless communications systems, e.g., various 802.11 wireless communications systems, are described. A novel shared transmission type of trigger frame is implemented, which allows a wireless station, acting as a host station, to make available transmission resources, which have been acquired by the wireless station, to one or more guest stations. A shared transmission type of trigger frame, generated and transmitted by the host station communicates information identifying the attributes of a corresponding trigger based (TB) frame, information identifying resources of the TB frame to be used by the host station and information identifying one or more set of shared resources which may be used by guest station(s). The trigger based (TB) frame, corresponding to the transmitted shared transmission type trigger frame, is used by the host station and one or more guest stations to transmit data to an access point.

Abstract: Apparatus and methods for prioritizing spectrum and controlling data traffic steering within a wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which allow network operators to prioritize utilization of spectrum for their subscribers. In one variant, an enhanced 3GPP UE Route Selection Policy (URSP) framework is provided for a UE connected to 5G wireless network, which allows the UE to use one or more prioritized 3GPP spectrum Band Class(es) based on one or more selection criterion or preconditions. In another variant, UE location information is used to dynamically update a data traffic steering mode or other functionality of an enhanced ATSSS (Access Traffic Steering, Switching, and Splitting) rule framework is described for dynamic control of steering or routing functionality, including between 3GPP- and non-3GPP network accesses for the data traffic.
