Aspects of the present disclosure are directed to use with communications that may involve repetitive communications. As may be implemented in accordance with one or more embodiments, a subset of symbols in a current data message (130/131) are used with a corresponding subset of symbols in a previous data message (120/121), to ascertain whether the current data message is a repetition of the previous data message. This may involve, for instance, generating a resemblance metric to represent semblance between a subset the data symbols of the current data message and a subset the data symbols of the previous data message (102). The resemblance metric can be used in determining whether the current data message is a repetition of the previous data message. This approach may be useful, for example, in ascertaining whether the current message is a repetition without necessarily decoding the message.

A route selection system includes a hub controller in communication with multiple network hubs of a first network domain in which each of the hubs are in communication with a corresponding multiple routers of a second network domain. The hub controller is executed to obtain at least one performance measurement associated with a route terminating at the network hub, generate a border gateway protocol (BGP) advertisement with a preference value that is proportional to the received performance measurement, and transmit the generated advertisement to the network hub, the network hub forwarding the advertisement to the router configured in the other network domain. Upon receipt of the advertisements, the second network domain selects one of the routers for processing the route through the second network domain according to the performance measurement included in the advertisement.

A base station device includes, a transmitter that transmits first data of a first type and second data of a second type, and a controller that is able to omit, when the transmitter multiplexes the first data and the second data together and transmits the first data and the second data multiplexed together, at least a portion of a segmentation offset or at least a portion of a reserve bit included in an RLC header of the second data.

An Internet of Things data transmission method includes sending, by a terminal device, a first data request to a server, and continuously receiving, by the terminal device, N data packets from the server. The first data request instructs the server to continuously send a plurality of data packets. The first data request includes a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1. The N data packets include at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets and the at least one NON data packet indicates that sending a receiving response from the terminal device to the server is unnecessary.

Embodiments of the present disclosure describe methods and apparatuses for adjusting contention window size for new radiounlicensed operation.

Systems and methods are disclosed for minimizing latency between receipt of a NACK at a base station from a user equipment (UE) and retransmission of data to the UE. Time constraints for processing the ACK/NACK are relaxed so the base station can decode the ACK/NACK to determine whether a NACK has been received and then prepare for transmission of the appropriate data to the UE in the immediately following transmission time interval (TTI). These constraints are relaxed by separating download data indicator (DDI) from the PDCCH control data and delaying transmission of the DDI until decoding of the ACK/NACK.

Aspects of the disclosure are directed to methods and apparatuses for wireless vehicular communications involving the transmission of messages using two or more protocols. As may be implemented in accordance with one or more embodiments characterized herein, wireless station-to-station communications are carried out in which a plurality of stations (210, 212, 214) share a wireless communications channel. Information is wirelessly collected (213) respectively from transmissions associated with a legacy communication protocol and another type of communication protocol. A current communication environment of the station is dynamically discerned (211) and characterizes a dynamic relationship of the collected information using the legacy communication protocol relative to the collected information using the other communication protocol. Communications are wirelessly transmitted (216, 218, 219, 220) over the wireless communications channel using the legacy and other communication protocol, by allocating usage of the channel through transmissions of data, via the legacy communication protocol and via the other communication protocol, based on the dynamic relationship.

The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

Communication devices are provided that facilitate receiving information units and providing feedback to other communication devices.

The present disclosure relates to an unmanned aerial vehicle (UAV), a terrestrial station thereof and a data transmission method.A data transmission method is applied to a terrestrial station and the method includes: receiving data packets continuously sent by a UAV; detecting continuity of data packet sequence numbers of the received data packets; and sending a data packet retransmission request to the UAV according to a lost data packet sequence number if it is detected that the data packet sequence numbers corresponding to the data packets are discontinuous. Adopting the UAV, the terrestrial station and the data transmission method that are provided in the present disclosure can effectively improve utilization of an uplink transmission link.
