摘要:
A method and a networking device for transmitting an information stream are provided. The method is executable by a router. The router and a device are located on-board a vehicle and communicatively coupled by an on-board LAN. The router is communicatively coupled to external systems. The method comprises: establishing a first channel between the device and a first external system by using the on-board LAN; transmitting, via the first channel, the information stream; monitoring decision metrics associated with external systems; identifying a second external system to be prioritized over the first external system; switching from the first to a second channel, the switching being seamless to a user, the switching comprising establishing the second channel between the device and the second external system by using the on-board LAN, storing a portion of the information stream; and transmitting via the second channel, the information stream without interruption during the switching.

A method is performed by a source Central Unit (CU) in an Integrated Access and Wireless Access Backhaul (IAB) network. The method includes transmitting, by the source CU, a message requesting a handover of a plurality of migrating devices associated with a first IAB node migrating from the source CU to a target CU. The message comprises at least one globally unique identifier of at least one management function serving the plurality of migrating devices.

A wireless local area network (WLAN) communication method and apparatus using multiple transmission speed partitioning and cooperative transmission are disclosed. The WLAN communication method includes transmitting, by access point to the nodes, transmission time slots, partitions and internal transmission priorities using transmission time slot information, partition information and internal transmission priority information, receiving uplink packet from one node, determining whether downlink data to be transmitted to the high speed or the low speed node is present, or not in the download queue, transmitting, if present, the downlink packet to the nodes, removing downlink data from the download queue for ACK, and transmitting, if not present, transmitting ACK to the nodes.

Disclosed are a method and a device for group handover in a communication system. An operation method of a header terminal comprises the steps of: transmitting a configuration information message including a first indicator indicating a measurement reporting subject to member terminals participating in the sidelink groupcast communication; if the measurement reporting subject indicated by the first indicator is the header terminal, receiving, from the member terminals, measurement reporting messages including results of measurement operations performed for at least one neighboring base station; and transmitting a configuration reporting message including the results of the measurement operations to a serving base station accessed by the header terminal. Therefore, the performance of the communication system can be improved.

In one example, a repeater system includes a master unit on a movable object configured to couple to antennas for receiving a downlink RF signal from at least one base station external to the movable object and for transmitting an uplink RF signal towards the at least one base station; and a plurality of remote units each configured to couple to the master unit, each positioned on the movable object and associated with different coverage areas, the remote units each configured to couple to a respective antenna system for transmitting the downlink RF signal into respective coverage areas and for receiving the uplink RF signal from the coverage areas, a control unit, wherein, for at least a subgroup of the remote units, a gain for each remote unit is dynamically adjusted in a time-offset fashion by the control unit to trigger handovers between overlapping base-station cells in a time-offset manner.
摘要:
Antenna nodes are controlled to maintain a respective radio cell, each cell having one and the same physical cell identity. The antenna nodes are further controlled to maintain the respective radio cell in a single direction substantially along a path such that each wireless communication device, during movement in a movement direction along the path, can connect either to consecutive antenna nodes towards which the wireless communication device is moving or connect to consecutive antenna nodes away from which the wireless communication device is moving.

Provided are a method and an apparatus for providing point-to-multipoint transmission in a single cell in a mobile communication network. The method may include receiving system information for single-cell multi-transmission in a primary cell (PCell); receiving single-cell multi-transmission control information in the primary cell; and checking whether a neighboring cell provides a single-cell multi-transmission, using the single-cell multi-transmission control information.

A method includes receiving, by a processor of a data collector, a request for sensor data related to an event. The method also includes sending a plurality of requests for the sensor data to a plurality of on-board units (OBUs), respectively, where the plurality of OBUs is associated with a plurality of vehicles, respectively. The method further includes receiving a plurality of responses from the plurality of OBUs, respectively, wherein each response of the plurality of responses includes a sensor data item related to the event. In more specific embodiments the plurality of requests are sent to the plurality of OBUs based on the plurality of OBUs being located within a certain proximity to the event. In yet further embodiments, each sensor data item of the plurality of responses is encapsulated with a respective tag.

Integration of a land mobile radio (LMR) communications system and other wireless IP based systems such as LTE by way of a multi bearer router. The LMR system may be either trunked or conventional. The multi bearer router maintains LMR IDs and also IP addresses for base stations, multi bearer terminals and other components of the integrated system.

In an embodiment, an access network (AN) receives a message configured to prompt a conditional allocation of Quality of Service (QoS) resources to an access terminal (AT). The message can be received from the AT or from an application server (AS) that arbitrates a communication session for the AT. In another embodiment, if the AT determines that a QoS resource request has not yet been granted, the AT waits until the traffic channel (TCH) has been obtained for a communication session before resending the QoS resource request. In another embodiment, if the AT determines to initiate or join a second communication session before a confirmation that QoS resources for a first communication session are relinquished, the AT waits until the confirmation is received before a request for QoS resources for the second communication session is sent.
