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: 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 first wireless communications device including a transmitter, such as a base station or UE, identifies a first traffic flow, e.g., a TCP packet flow, for which end to end packet retransmission is supported. The first wireless communications device transmits an explicit indication to a second wireless communications device to skip Hybrid Automatic Repeat Request (HARQ) feedback for data, corresponding to the first traffic flow, said data being transmitted to the second wireless communications device. The explicit indication to skip HARQ feedback for data is, e.g., one of: a HARQ Off Indicator in a Downlink Control Information (DCI) Scheduling message, a Semi-Persistent Scheduling HARQ Off Indicator, or a AUL HARQ Off Indicator. HARQ suppression is applied for the first traffic flow at a radio link layer and/or MAC layer.

Abstract: Apparatus and methods for streamlined cell activation in a wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which utilize bandwidth-efficient setup/configuration messaging and cell activation, including for very large numbers of cells, and which do not overwhelm data backhaul(s) associated with wireless nodes used for communication. In one embodiment, a message protocol is used wherein a prescribed number of cells of a given DU (e.g., all, a prescribed subset, etc.) are activated without having to enumerate or include specific data relating to the cells being activated. In one variant, this “global” activation is conducted using an Activate All Cells IE (Information Element) disposed with the F1SETUP RESPONSE message issued by a controlling CU entity within a 5G-NR infrastructure. In other variants, cells of multiple DUs can be controlled simultaneously, such as via distribution of a system-wide global activation IE.

Abstract: A user equipment has been allocated uplink resources, e.g. interlaced uplink channel resources, e.g. interlaced physical uplink shared channel (PUSCH) resources, and non-interlaced uplink channel resources. The UE receives cancellation indication (CI) information which rescinds the allocation for a portion of the previous granted resources. CI is communicated using different formats for resources which are in blocks and resources which are interlaced. The CI for the interlaced resources uses a more efficient format with less overhead to communicate frequency information corresponding to the cancellation for the interlaced channel.

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 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 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: 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.
