Aspects of the present disclosure provide techniques for using a radio access network (RAN) level negative acknowledgement (NAK) feedback to indicate at least one missing frame from an encoding device. The RAN level NAK feedback replaces or preempts a decoding device sending an end-to-end feedback to the encoding device using real-time transport protocol (RTP) that has a long latency and may cause freezes at the decoding device. For example, an encoding device may send to a network entity a request for a configuration that configures the encoding device to transmit media frames to the decoding device. The network entity may provide a NAK feedback indicating at least one missing frame. Having received the configuration in response to the request, the encoding device transmits media frames to the decoding device via the network entity, and monitors for NAK feedback from the network entity in accordance with the configuration.

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 share a wireless communications channel. Information is wirelessly collected 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 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 over the wireless communications channel using the legacy and other communication protocols, 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.

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.

Control information (126) related to the reception of data (128) within a subframe (116) is transmitted over multiple subframes (113, 116) over multiple carrier (107, 108) from communication system infrastructure (102). A controller (134) in a mobile wireless communication device (104) reconstructs the control information (126) received over multiple subframes (113, 116) based on at least some control information (130) in a first physical control channel (118) in a first subframe (113) transmitted over a first carrier (107) and at least some other control information (132) in a second physical control channel (120) in a second subframe (116) transmitted over a second carrier (108).

Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

A computer-implemented method, and a related system, for facilitating data communication of a trusted execution environment. The method includes: processing a plurality of data packets to form a data stream including the plurality of data packets. Each data packet includes respective metadata. The data stream is a single continuous data stream in application-layer such that a boundary between two adjacent packets are not easily identifiable. The method also includes transmitting the data stream to or from a network interface module for the trusted execution environment.

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.
