摘要： It is provided a method for processing input media data. The method is performed in a media data processor and comprising the steps of: obtaining input media data; identifying, in the input media data, sensitive information; generating replacement information, wherein the replacement information is at least partly anonymised information corresponding to the sensitive information, and the replacement information contains at least one characteristic based on the sensitive information; modifying the input media data by replacing its sensitive information with the replacement information, resulting in a modified media data; and providing the modified media data for further processing.

摘要： The proposed technology generally relates to radio resource management in wireless communication systems, which operate based on directive beams for serving one or more wireless user devices (120). A basic idea is to process image information obtained from one or more image sensors (115) to predict a change in radio propagation characteristics between a network node (110) of the wireless communication system and a user device (120), and to control a mobility reference signal for at least one directive beam in the wireless communication system and/or configure measurements of the mobility reference signal and/or configure reporting and/or processing of measurement results from measurements of the mobility reference signal, based on the predicted change in radio propagation characteristics.

摘要： A first communication device (110) and method therein for transmitting a message generated in the first communication device (110) to a second communication device (120) in a wireless communication network (100) is disclosed. The first communication device, prior to transmission of the message being triggered, encodes, or encodes and modulates, the message into more than one data packet variants using different combinations of coding and/or modulation parameters for the more than one data packet variants. When transmission of the message is triggered, the first communication device (110) receives, from the second communication device (120), information about physical transmission resources and/or physical layer parameters assigned to the first communication device (110). The first communication device (110) then transmits the message using one of the data packet variants where the used data packet variant is selected based on the received information about physical transmission resources and/or physical layer parameters.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

摘要： The present invention relates to a method and apparatus for requesting scheduling of resources to be used for uplink communication of data in a communications system. If the repeated transmission by a user equipment of scheduling requests on an uplink control channel is determined to be unsuccessful, a random access transmission on a random access channel is initiated as a fallback procedure.
