A communication apparatus includes a setting unit that sets a time interval with respect to a timing of communicating with an external apparatus, a communication unit that communicates with the external apparatus at the time interval, and a control unit that performs control to, based on a request of the operation through the remote operation received from the external apparatus, communicate with the external apparatus in one of a plurality of modes including a remotely operated mode in which an operation corresponding to a requested operation is executed, wherein, in a case where a mode is shifted to the remotely operated mode, the setting unit changes the time interval to a shorter interval, and the control unit performs control to notify a user that the time interval is a long interval until a change of the time interval is completed.

The present invention relates to a method for allocating communication resources in a multi-user cellular communication system, wherein communication resources are divided in time periods and frequency sub-bands, wherein part of the communication resources are used for frequency-localized communication channels, and part of the communication resources are used for frequency distributed channels. The method further comprises the steps of: classifying part of the frequency sub-bands as frequency sub-bands carrying frequency-distributed channels, classifying the remaining part of the frequency sub-bands as frequency sub-bands carrying frequency-localized channels. The present invention also relates to a system, a transmitter and a communication system.

A radio receiving apparatus for receiving the variable-length RLC PDU data in an RLC layer includes the buffer memory sectioned into a plurality of areas having a predetermined maximum data length of the RLC PDU data. By referring to a sequence number SN included in each received RLC PDU data, the radio receiving apparatus stores the RLC PDU data having an identical sequence number SN into an identical area, and assembles an RLC SDU data on a basis of the RLC PDU data stored in each area.

The present invention relates to a system that includes a transmission/reception point and a user equipment having different configurations in inter-band and performs a TDD (Time Division Duplex) method.

This application provides a method and device for generating a subframe, a method for determining a subframe and a user equipment. The method for generating a subframe includes: determining, by a first device, patterns of at least two special subframes used in a broadcast control channel modification period, where guard period GP durations of the at least two special subframes are different; and generating, by the first device, the at least two special subframes. The method enhances flexibility and improves a system resource utilization rate.

Various embodiments disclosed herein provide for the provisioning of backhaul links over a 5G NR (New Radio) integrated access and backhaul (IAB) network for access nodes using non-5G radio access technologies. In this way, the IAB network can service devices that are connected to the core network via older 3GPP technologies, or even non-3GPP technologies such as Wi-Fi. An IAB mobile terminal can be provided at the end point access node to make the access node an IAB node. Using an existing internet protocol (IP) routing in the IAB network, or providing for an IP tunnel between the endpoint access node and the core network can then facilitate providing backhaul services for the non-5G access node.

Techniques for improving real-time communications over a mobile network are provided. In one aspect, a method for managing data transfer in a mobile network wherein user equipment transmit data through one or more cell towers is provided. The method includes the steps of: intercepting data packets from the user equipment; determining a location of a given one of the cell towers in the mobile network to which the data packets are to be sent; and tunneling the data packets directly to the given cell tower. A system for managing data transfer in a mobile network wherein user equipment transmit data through one or more cell towers is also provided.

Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a satellite terminal comprises one or more processors; and one or more non-transitory computer-readable storage media configured with instructions executable by the one or more processors to cause the satellite terminal to perform operations comprising: communicating, using the satellite terminal, over an inroute TDM channel; determining, based on an ingress traffic rate to the satellite terminal or a determination that the satellite terminal has not received any traffic flows classified for communication using TDM, to switch communications from the inroute TDM channel to an inroute TDMA channel; and after determining to switch communications, switching, at the satellite terminal, from communicating over the inroute TDM channel to communicating over the inroute TDMA channel.

A network or system in which a hub or primary node may communicate with a plurality of leaf or secondary nodes. The hub node may operate or have a capacity greater than that of the leaf nodes. Accordingly, relatively inexpensive leaf nodes may be deployed to receive data carrying optical signals from, and supply data carrying optical signals to, the hub node. One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, optical splitters/combiners, and optical add/drop multiplexer, for example. Optical subcarriers may be transmitted over such connections, each carrying a data stream. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced. As the bandwidth or capacity requirements of the leaf nodes change, the number of subcarriers, and thus the amount of data provided to each node, may be changed accordingly. Each subcarrier within a dedicated group of subcarriers may carry OAM or control channel information to a corresponding leaf node, and such information may be used by the leaf node to configure the leaf node to have a desired bandwidth or capacity.

Systems, methods, and apparatuses are described for wireless communications. A wireless device may transmit an uplink signal via a cell of a cell group. Transmission timing of the uplink signal may be based on a cell of the cell group and a timing adjustment associated with a different cell group.
