Abstract: Systems and methods are disclosed herein for performing a failover operation between a first distributed database cluster and a second distributed database cluster. In one aspect, the method includes blocking a plurality of software processes from making any new access requests to the first distributed database cluster and completing a current access request to the first distributed database cluster that was initiated by one of the plurality of software processes before the failover operation was initiated, waiting for data to replicate from the first distributed database cluster to the second distributed database cluster, wherein replicating includes any changes to the data from the current access request, and allowing the plurality of software processes to make the new access requests to the second distributed database cluster once the replicating has completed.

Some embodiments of the method include accessing, at user equipment, a first bit rate selected from a plurality of bit rates used to encode a portion of an adaptive multimedia stream, a size of the portion of the adaptive multimedia stream, and a play out duration of the portion of the adaptive multimedia stream. Some embodiments of the method also include providing, from the user equipment, indications of the first bit rate, the size, and the play out duration.

Abstract: Embodiments relate to apparatuses, methods and computer programs for a mobile transceiver, a base station transceiver and a data server. A mobile transceiver apparatus (10) comprises means for extracting (12) context information from an application being run on a mobile transceiver (100), context information from an operation system being run on the mobile transceiver (100), or context information from hardware drivers or hardware of the mobile transceiver (100), the context information comprising information on a state of the application and/or information on a state of the mobile transceiver (100). The apparatus (10) further comprises means for communicating (14) data packets with the base station transceiver (200), wherein the data packets comprise payload data packets and control data packets, and wherein the means for communicating (14) is operable to communicate payload data packets associated with the application with a data server (300) through the base station transceiver (200).

Abstract: A concept for scheduling in a communication system (500). The communication system comprises a mobile transceiver (100), a base station transceiver (200) and a data server (300). A scheduling concept at the base station transceiver (200) is based on context information determined by the mobile transceiver (100), the base station transceiver (200) and/or the data server (300).

Abstract: The present invention refers to methods and apparatus for simultaneous transmission and reception of a data sequence (d) and channel information (CI) for link adaptation. In order to provide a method, a transmitter element (34), and a receiver element (38) that consume less transmission resources and improve the overall spectral efficiency of the network, a method and a transmitter element (34) for simultaneous transmission of a data sequence (d) and channel information (CI) for link adaptation over a radio channel (29) of a wireless network (11) is suggested, the method A comprising encoding said data sequence to a codeword (c) using a channel encoder (19) and transmitting (21) the codeword (c) over the radio channel (29), wherein the method further comprises including the channel information (CI) into the codeword (c) using said channel encoder (19), the codeword (c) comprising both the data sequence (d) and the channel information (CI).

Abstract: The present invention refers to a method and a transmitter element (35) for transmitting channel information (CI) for link adaptation of a radio channel (33) in a wireless network (11). In order to allow for reliable and efficient transfer of the channel information (CI) and to adapt the detection probability to the importance of the CI as well as to the channel stability, it is suggested that the method comprises encoding (19) the channel information (CI) using multi-level coding, said multi-level coding (19) comprising combining multiple bit sequences (c1, c2, . . . , cn, d), each bit sequence (c1, c2, . . . , cn, d) corresponding to a coding level (1, . . . , n) of said multilevel coding (19) and assigning (37) one of said coding levels (1, . . . , n) to at least a part (ci1, ci2) of the channel information (CI) such that at least a part (ci1, ci2) of the channel information (CI) corresponds to the bit sequence (c1, c2, . . . , cn) of that coding level (1, . . . , n).
