Disclosed herein are system, method, and computer program product embodiments for NR cell prioritization based on carrier bandwidths. An embodiment operates by storing a plurality of neighboring cell frequencies and respective carrier bandwidths of the plurality of neighboring cell frequencies. The embodiment determines whether a carrier bandwidth corresponding to a neighboring cell frequency of the plurality of neighboring cell frequencies is less than a serving cell carrier bandwidth. In response to a determination that the carrier bandwidth corresponding to the neighboring cell frequency is less than the serving cell carrier bandwidth, the embodiment determines a biased signal strength measurement by adding an offset to a signal strength measurement corresponding to the neighboring cell frequency, where the offset is determined based at least in part on a data throughput requirement of the UE. The embodiment evaluates a signal strength criteria of the neighboring cell frequency using the biased signal strength measurement corresponding to the neighboring cell frequency.

A wireless communication system, a communication method, and a portable transceiver device are provided. The wireless communication system includes a server, a plurality of gateway devices and user-end portable transceivers that are interconnected by a wireless WAN protocol, e.g. LoRa. Each portable transceiver connects a user device via a near-end wireless communication protocol that allows the user device to connect with the server via a gateway device. After the user device sends a message through the portable transceiver, the server discovers another portable transceiver and another gateway device according to a destination address. Thereby, the message can be transmitted via this connection, or a direct voice communication can be performed via a communication channel over this connection. The communication system therefore provides a communication service under the wireless WAN protocol that is an alternative to traditional mobile communications.

A method, apparatus, and system for lessening impact of connected mode mobility measurement is disclosed. A user equipment (UE) may reduce network management complexity by autonomously collecting signal quality measurements for neighboring cells. By autonomously tuning at opportune times for the UE, signal quality measurements may be obtained and reported to a serving cell. In another implementation, the UE examines the broadcast system information of both the serving base station against that of the neighboring base stations. Based on the included bandwidth information, the UE selects appropriate narrowband radio frequency subcarriers to perform signal quality measurement.

There is provided a node for operating in a wireless network, including: coarse-granularity scanning circuitry that performs a coarse-granularity scanning process to detect one or more donor nodes of the wireless network according to a first metric. Connection circuitry forms a connection to a selected donor node in the one or more donor nodes. The connection is broken as a consequence of the coarse-granularity scanning process being performed. Fine granularity scanning circuitry performs a fine granularity scanning process to determine a configuration in which a quality of the connection is improved according to a second metric. The connection is maintained during the fine granularity scanning process.

A computer-implemented method (1400) performed in a radio access network (1510) for secondary carrier prediction is provided. The method includes obtaining (1402) an uplink channel impulse response based on a reference signal transmitted by a user equipment (UE) (104) over a primary carrier link to a serving network node (102) in a primary cell (102) currently serving the UE (104). The method includes extracting (1404) one or more features from the uplink channel impulse response. The method includes predicting (1406) an existence or non-existence of a secondary carrier link between the UE (104) and a target network node in a secondary cell (106) based on the extracted one or more features. The method includes determining (1408) whether to perform a handover procedure of the UE (104) from the serving network node in the primary cell (102) to the target network node in the secondary network cell (106) based on the predicting.

A processing method includes: determining at least one of first conditions in a first situation, by a second wireless apparatus in a system which includes a first wireless apparatus and a plurality of the second wireless apparatuses, the first situation being when the wireless apparatus operates in an idle mode and when communication between the wireless apparatus and the one other second wireless apparatus is performed via a first channel, the first conditions including whether a quality of the first channel is lower than a predetermined quality and whether a switching instruction is received; and executing a first process by the second wireless apparatus when the at least one of first conditions is met, the first process including establishing a second channel between the second wireless apparatus and the first wireless apparatus, and switching from communication via the first channel to communication via the second channel.

This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.

Disclosed are a mobility management method, a radio access network, a terminal and a computer storage medium. The method includes: sending, to a terminal, a configuration message, and the terminal reports, according to the configuration message, neighbor cell signal strength or terminal position information; and after a measurement report, which is reported by the terminal and includes the neighbor cell signal strength or the terminal position information, has been received, according to the measurement report and position information of an NG-RAN, determining whether a specified condition allowing the terminal to carry out neighbor cell handover is satisfied, and if so, sending a cell handover message to the terminal, and the terminal is handed over from the current cell to a target cell, and the specified condition is a condition allowing the terminal to carry out neighbor cell handover.

A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for link changes. Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective automation of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.

A method of operation of a wireless communication device to perform handover from a source cell to a target cell in a wireless communication system is provided. The wireless communication device performs (202) a beam tracking procedure for one or more neighbor cells to provide, for each neighbor cell, a list of tracked beams for the neighbor cell. The wireless communication device receives (212) a handover command from a source radio access node that instructs the wireless communication device to perform a handover from a source cell served by the source radio access node to a target cell served by a target radio access node. The target cell is one of the one or more neighbor cells for which the beam tracking procedure is performed. The wireless communication device then selects (214) a beam of the target cell from the list of tracked beams for the target cell based on random access resource configuration and/or a quality threshold. The wireless communication device then performs (216) random access on the selected beam.
