Abstract: Methods and apparatus used to facilitate preparation of one or more target base stations for possible UE handoffs, e.g., conditional handoffs, which may or may not occur depending on whether or not various handoff conditions are satisfied are described. A handoff message, e.g., a conditional handoff message, including a validity time is generated and sent to each selected target base stations to which a UE may be handed off. The validity time indicates to the target base station a time window, e.g., a time duration for which the handoff target message is to be considered valid. In response to the handoff message, the target base station, receiving the handoff message, allocates resources to the UE and starts a countdown validity timer based on the indicated length of the validity time. When the validity timer expires without handoff to the target base station, the target base station releases the allocated resources.

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: 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 using a QUIC connection established between a user equipment (UE) and a Non-3GPP InterWorking Function (N3IWF) to support untrusted non-3GPP access which facilitates Access Traffic Steering, Switching, and Splitting (ATSSS) are described. An exemplary N3IWF, implemented in accordance with features of the present invention, implements MASQUE over QUIC. In some embodiments, the Multiplexed Application Substrate over QUIC Encryption (MASQUE) over QUIC implementation as the transport for NAS. In some embodiments, QUIC connection IDs are used to delineate control plane (CP) traffic and user plane traffic being communicated over the established QUIC connection. In other embodiments, a new 3GPP Payload type header is used to delineate between control plane (CP) traffic and user plane traffic communicated over the established QUIC connection.

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: Data packet congestion marking is supported in devices which may form part of a communications path. The devices which can perform marking can, and in some embodiments do, include non-gNB devices and non-anchor point UPFs, e.g., devices other than gNBs and PSA UPFs such as intermediate UPFs, N3IWFs, TNGFs, and W-AGFs, in addition to gNBs and anchor UPFs. Intermediate UPFs corresponding to a communications session will set the congestion indicator value in a data packet's IP header, of a data packet passing through the UPF, to indicate congestion, if it is not already set to indicate congestion when congestion is detected at the intermediate UPF. A session management function in some embodiments controls which devices perform congestion marking and enables/disables congestion marking, e.g., on a per communications session basis while the session is ongoing and/or at various times during a session establishment or device registration process.

Abstract: Methods and apparatus for providing quasi-licensed intra-cell spectrum reassignment. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a “seamless” reassignment of wireless spectrum without disruption or loss of continuity to existing data sessions of the CBSD is provided via a pool of temporary RF carriers which act as substitutes for the currently allocated (granted) carriers. The served user devices (e.g., UEs) are instructed by the CBSD to migrate to a new “final” carrier via the substitutes, either directly or via one or more intermediary hops. In one variant, existing 3GPP signaling mechanisms between the UE and CBSD/eNodeB obviates any changes to extant UEs. Communications between the CBSD and its cognizant SAS/DP include new information objects which direct the CBSD to implement the handover functionality. In a further variant, inter-CBSD sector and frequency handovers are provided for using CBRS-plane and 3GPP signaling.

Abstract: Methods and apparatus for supporting prioritized transmission opportunity (TXOP) sharing in wireless communications systems, e.g., various 802.11 wireless communications systems, are described. A wireless station may be allocated a transmission opportunity. A shared transmission type of trigger frame is implemented, which allows the 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 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. An access point transmits priority information, e.g., in management frames, to control the use of shared resources in TB frames corresponding to shared transmission type trigger frames. The priority information identifies which particular stations are authorized to be a guest station corresponding to a particular transmission opportunity.

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.
