Measurement-based random access configuration
摘要
說明書
In various embodiments, the burst containing synchronization signal(s) and measurement RS's also contains basic system information, which in some embodiments include one or more parameters related to the measurement RS. In some embodiments, the basic system information is a block of channel encoded information bits modulated onto a set of sub-carriers in a multi-carrier system. In other embodiments, the bits are modulated onto single-carrier waveform(s). In some embodiments, a burst that contains broadcasted system information, or a certain piece of system information, also contains a transmission of one or more certain measurement RS's. In some embodiments, a device may assume that the system information, or a certain piece thereof, is available in the burst if measurement result(s) for the one or more measurement RS(s) in the same burst are above certain threshold(s), and where the measurement is not averaged over multiple bursts. These embodiments can be used by the network or a TP to let only a fraction of the bursts contain broadcasted system information, or certain pieces of system information. Devices would be notified by the presence of the information by the presence of a measurement RS. In some embodiments, the measurement RS(s) related to the presence of system information, or pieces of system information, may also be used to demodulate the broadcasted system information.
