Abstract: A user equipment (UE) receives time division duplexing (TDD) configuration information from a master node (MN), with which the UE is communicating using a first band of unlicensed spectrum and receives TDD configuration information from a secondary node (SN), which is being added to support communications with the UE using a second band of unlicensed spectrum. The UE compares the two TDD structures, identifying DL and UL slots in SN TDD structure which correspond to DL and UL time intervals in the MN TDD structure, designating at least some of those SN slots as preferred DL slots and preferred UL slots. The UE communicates information indicating its preferred DL slots and preferred UL slots in an assistance message to the SN. The SN using UE slot preference information, selects DL and UL slots to be used for UE communications and implements a TDD structure, which avoids an IDC problem.

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: 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: 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: In certain embodiments, a (CBSD) base station for a (CBRS) radio system transmits new information elements in an existing capability exchange message to a spectrum access system (SAS) informing the SAS as to whether the SAS should transmit a channel-change message to the base station either (i) directly (and despite of domain proxy being present in the communication path) or (ii) via a domain proxy. If and when the SAS subsequently receives notification of incumbent activity from an Environmental Sensing Capability system, the SAS transmits either a new channel-change message or includes new information elements in an existing heartbeat message to the base station either (i) directly or (ii) via the domain proxy per the capability exchange message. The SAS can combine multiple channel-change messages for multiple base stations into a single message for transmission to a domain proxy that can communicate with those multiple base stations, thereby reducing communications to and from the SAS and decreasing the time that it takes to change channels without jeopardizing existing traffic.

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.

Abstract: Apparatus and methods for registration of e.g., mobile devices in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given mobile device (e.g., a 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs) of respective different operators. In one implementation, the UE operates in dual-registration mode or DRM to allow different interworking between the two networks, and includes independent registration capability to 5GC and EPC infrastructure simultaneously. Accordingly, the UE is provided umbrella 4G/4.5G coverage over one or more small-cell 5G networks, with respective independent operators of each. Enhanced DRM-UEe capability as described herein advantageously allows for service provision (e.g., voice service) and interworking between the macro and small-cell layers of the system without complicated network configuration requirements between the two operating networks.

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: 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.
