摘要： 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.

摘要： A master node (MN) communicating with a UE using resources of a first band of unlicensed spectrum sends an addition request to a selected secondary node, to request resources for supporting the UE in a second band of unlicensed spectrum. The addition request includes timing information including one or more of: i) information indicating a start time for the MN time division duplexing (TDD) timing structure with respect to the UE, or ii) information indicating a reference clock being used by the MN. The secondary node uses the received timing information from the MN to perform timing alignment at the secondary node. The adjusted timing alignment of the secondary node allows the UE to achieve slot-boundary and/or symbol boundary alignment with regard to MN communications using the first unlicensed spectrum and SN communications using the second unlicensed spectrum. Due to the achieved synchronization, an in-device coexistence (IDC) problem is avoided.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In a further aspect, a method of operating a wireless access node connected to one or more wireless user devices is disclosed. In one embodiment, the wireless access node is connected to the one or more wireless user devices through a first frequency channel located in an unlicensed spectrum, and the wireless access node is a 3GPP NR gNB including an enhanced central unit (CUe) and/or at least one enhanced distributed unit (DUe) connected to the central unit. In one variant, the method includes: performing interference (e.g., radar) detection in the first frequency channel using the wireless access node; based on detection of interference, selecting at least one second frequency; and sending instructions to the one or more wireless user devices from the wireless access node, the instructions configured to make the one or more wireless user devices switch to the at least one second frequency. In one implementation, the at least one second frequency includes a plurality of different frequencies.
