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: Apparatus and methods for improving coverage and/or power-saving in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device (such as e.g., a 3GPP-compliant UE) to utilize downlink transmissions related to a first access technology (e.g., LTE) to enhance the detection and reception of downlink transmissions from a second access technology (e.g., 5G NR). In one variant, transmissions relating both access technologies are multiplexed on a shared frequency channel; a UE trying to detect 5G NR transmissions from a gNB leverages the easier detection of certain LTE signals such as PSS to enhance detection of the 5G NR signals. Moreover, the location of the LTE PSS (or SSS) can be used to indirectly assist a
UE with detection of the NR SSB, such as via reduction of the number of noise-only samples passed to the NR PSS/SSS autocorrelation detector.

Abstract: According to one configuration, a system includes a mobile communication device. The mobile communication device includes monitor hardware operative monitor for presence of a repetitive pattern present in received wireless communications present in a network environment. Depending on a magnitude of wireless energy of a portion of received wireless communications including the repetitive pattern, communication management hardware of the wireless station controls transmission of wireless communications from the wireless station. Thus, depending on a detected energy level of the monitored wireless signals having a particular signature (such as the repetitive pattern), the mobile communication device controls subsequent transmission of wireless communications from the mobile communication device in the network environment.

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: Methods and apparatus for supporting transmission bursts in unlicensed spectrum are described. Different sets of sub-bands within a downlink bandwidth portion of unlicensed spectrum can be, and sometimes are, occupied during different DL transmission bursts depending on channel availability. A user device is configured with channel usage information, e.g. N bitmaps, each bitmap indicating a different control channel resource allocation that may be used for communication with the UE, and/or reference signal information. The UE determines the occupied sub-bands in a DL transmission burst over the bandwidth portion, and determines control channel resource information based on the determined occupied sub-channels. The UE determines CSI-RS measurement locations based on determined sub-band occupancy. In some embodiments, the UE performs in-sync and out-of-sync evaluations based BLER threshold scaling factors, which are based on sub-band occupancy.

Abstract: According to one configuration, a system includes user equipment in communication with a wireless base station. The user equipment receives a notification from a first wireless access point of multiple wireless access points. The notification indicates a set of candidate wireless access points in the wireless network environment in which to selectively perform a handoff from a first wireless access point. The user equipment monitors for occurrence of a trigger condition. In response to detecting a trigger condition, the user equipment identifies (such as selects) a second wireless access point (from the set of candidate wireless access points) in which to perform the handoff. Via communications from the user equipment to the second wireless access point, the user equipment initiates the handoff. The user equipment notifies the first wireless access point of the attempted and/or failed attempt of the handoff to the second wireless 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 N R-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.
