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 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 UE is supplied with one or more UE Route Selection Policy (URSP) rules which include an indicator indicating support for a “L4S” Connection Capability. The use of an L4S connection capability indicator allows a UE to obtain L4S support for application traffic data requiring L4S support. The connection capabilities option in the URSP rule or rules allows a UE to select an appropriate route selection for matching L4S connection capability. By allowing a UE to indicate that a packet or packet flow is to be matched to a PDU session which has an L4S connection capability, the UE can trigger establishment of a new PDU session to support a flow of application data packets requiring L4S support or can cause the packet flow to be assigned to an existing PDU session or trigger a modification of an existing PDU Session which supports L4S.

Abstract: Apparatus and methods for physical cell identification within one or more wireless networks. In one embodiment, conflicts in PCI values which may exist within two or more mobile networks (e.g., PLMNs) of respective different operators when unlicensed spectrum is utilized (e.g., according to 3GPP 5G NR-U technology) are resolved. In one implementation, this functionality is provided by specifying one or more mobility-related parameters associated with various UE, such that serving gNBs can determine whether a given UE requires a mobility context, and as such whether it should conduct subsequent RF measurement reporting to report back potential conflicts in PCI it may encounter to the gNB. In one variant, the measurement reporting is configured to comply with 5G NR-U required “listen-before-talk” or LBT protocols; i.e., to measure parameters consistent with the LBT protocols to detect any such PCI-based conflicts.

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 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: Apparatus and methods for multi-cell broadcast access channel utilization in a wireless network. In one embodiment, the apparatus and methods provide random access channel (RACH) procedure for a 3GPP-compliant user device (e.g., an enhanced UE or UEe) which attempts to connect to multiple cells simultaneously. In one variant, the UEe employs a multi-step (e.g., 4-step) RACH procedure to connect to the multiple cells. This significantly increases the likelihood of RACH procedure success and UEe access. In another variant, a 2-step RACH process is utilized. Variants of the apparatus and methods utilizing unlicensed spectrum and LBT (listen-before-talk) protocols are also described.

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.
