摘要： The present disclosure relates to reference signal design methods and devices. In one example method, a first communication device obtains at least one sequence from a subset of sequences in a set of sequences and obtains at least one reference signal based on the obtained at least one sequence. The sequence is phase rotated during its generation, phase rotated in the frequency domain, or cyclically shifted in the time domain based on a constant value Δq. The first communication device transmits the reference signal to a second communication device.

摘要： This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

摘要： A method for notifying a Real-Time Streaming Protocol (RTSP) event includes: monitoring an event state; and sending a notification indicative of a change of the event state to an event state receiving device if detecting the change of the event state. A computer program and a computer-readable storage medium are provided to enable a computer to perform the steps of the method for notifying an RTSP event. An apparatus for notifying an RTSP event includes: an event state monitoring unit, adapted to monitor an event state; and a message sending unit, adapted to send a notification indicative of a change of the event state when the event state monitoring unit detects the change of the event state. A system for notifying an RTSP event includes the RTSP event notifying apparatus.

摘要： The present disclosure relates to a client device and a network access node for transmitting and receiving a random access preamble which comprises a division of a set of resource blocks available for transmission of the random access preamble into at least two subsets of resource blocks, wherein each resource block in the set of resource blocks comprises a plurality of subcarriers, a first selection of resource blocks within the first subset of resource blocks and a second selection of resource blocks within the second subset of resource blocks, wherein the first selection of resource blocks is different to the second selection of resource blocks, and a mapping of a modulation sequence of the random access preamble onto at least one subcarrier in each selected resource block. Thereby, lower side-lobes of the auto-correlation function is achieved. Furthermore, the present disclosure also relates to corresponding methods and a computer program.

摘要： A network node for a wireless communication system includes a processor and a transceiver, the processor being configured to generate a set of at least two synchronization signal sequences; construct a synchronization signal for each synchronization signal sequence to create a set of synchronization signals, such that each of the synchronization signals in the set of synchronization signals has an auto correlation and cross correlation below a threshold value with any other synchronization signal in the set of synchronization signals; generate a set of directional beam patterns, wherein each beam pattern in the set of directional beam patterns corresponds to one of the synchronization signals in the set of synchronization signals; and wherein the transceiver is configured to transmit the synchronization signals in the set of synchronization signals using the beam pattern for each synchronization signal over a same time frequency resource.
