Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus configured to enable wireless stations to use their shared spectrum grants proximate a priority/incumbent user of the shared spectrum by generating a propagation model of the priority/incumbent user, determining a potential interference therewith by each of at least one group of similarly located wireless stations proximate the priority user, determining a modification to a spectrum grant for each wireless station group that would avoid interference with the priority/incumbent user by the respective wireless stations of the group, and updating the spectrum grants of each wireless station in a wireless station group using the determined spectrum grant modification associated with the wireless station group.

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: 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: Apparatus and methods for multi-carrier or multi-band utilization in an unlicensed wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which provide enhanced bandwidth capability to 5G NR-U entities such as gNodeB and UE devices across two heterogeneous unlicensed bands having different medium access mechanism and protocols. In one variant, LBT (listen before talk) protocols are used to detect the presence or absence of users within the respective bands of interest. When two or more unoccupied carriers or bands are identified, aggregated operation is used ti enhance the downlink/uplink (DL/UL) transmission bandwidth for the device(s).

Abstract: Apparatus and methods for operating multiple link premises devices in a wireless network. In one embodiment, premises devices such as a wireless gateway, Access Point (AP) or user devices use Wireless Local Area Network (WLAN) technology for the transmission of data on multiple links operating on different frequencies. The disclosed apparatus and methods provide a solution to share channel statistic or similar data across the different links, such as for link performance improvement via more optimal MIMO operation. In one implementation, large-scale channel statistics are shared via the pre-amble or mid-amble of a frame across multiple links between an AP and a user device to enhance receiver performance. In another embodiment, the channel statistics are shared between multiple AP devices which can coordinate with each other, and/or are made specific to individual client devices, in order to enhance receiver performance.

Abstract: According to one configuration, a system includes a first wireless station in communication with a second wireless station. A phase noise predictor model such as associated with the first wireless station receives phase noise information. The phase noise information captures an estimate of: i) first phase noise associated with a first wireless station, and ii) second phase noise associated with a second wireless station. Based on the received phase noise information, the predictor produces phase noise adjustment information. The predictor applies the phase noise adjustment information to adjust (compensate) a signal of the first wireless station. Adjustment of the signal results in phase noise adjustment with respect to both the first phase noise associated with the first wireless station and the second phase noise associated with the second wireless station.

Abstract: According to one configuration, while the user equipment is wirelessly connected to a first wireless base station over a first wireless communication link, a communication management resource in the user equipment receives input (such as a request) to tune-away the user equipment to a second wireless base station providing corresponding wireless services. To facilitate the temporary tune-away to the second wireless network, the communication management resource of the user equipment generates timing information associated with the switchover. In furtherance of the switchover (temporary tune-away) to the second wireless base station, the communication management resource of the user equipment transmits the timing information in a wireless communication over the first wireless communication link to the first wireless base station.

Abstract: Apparatus and methods for improving throughput and reliability in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device buffer management that mitigate buffer overflow within the device due to overscheduling, such as from different networks with which the device is connected simultaneously. In one variant, a 3GPP-based signaling architecture from wireless device to the multiple networks is provided to enable user device-controlled management buffer overflow. In another variant, potentially buffer-demanding (e.g., HARQ) process management and prioritization rules are defined to avoid buffer overflow. In other variant, buffer size computation is provided considering the number of networks to which the wireless user device can connect.
