    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: 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.

    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.

    Abstract: Apparatus and methods for segmentation of resource/control messages in a wireless system. In one embodiment, the messages being segmented are radio resource control (RRC) messages used in a downlink direction for a 3GPP 5G New Radio (NR) system. In various implementations, RRC segmentation in the downlink direction is enabled in a generic manner when message size exceeds a prescribed limit. A container format is specified, and messaging exchanged between the UE and base station (gNB) indicates (i) the UE's capability for receiving segmented messages, and (ii) data related to the segmented message that the UE can utilize to receive and reassemble the message, as well as a protocol to be followed upon detection of link failure. In one variant, a 4G/4.5G LTE/LTE-A configuration is disclosed.

    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.
