4 results about "Channel statistics" patented technology

Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) can measure a received power of one or more reference signals (such as channel state information (CSI) reference signals (CSI-RSs) or synchronization signal blocks (SSBs)) transmitted by a base station for a beam management procedure. The UE can determine, based on performing the beam management procedure, a set of channel statistics associated with a channel used by the base station to transmit the one or more reference signals. The UE can transmit, to the base station, a report including at least a received indication of the one or more reference signals and the set of channel statistics. The base station can select, based at least on the indication of the received power and the set of channel statistics, a beam and a channel for communication with the UE.

Embodiments of the present disclosure disclose a gNodeB. The gNB is configured to monitor network performance metrics for each of common channel signals. The network performance metrics comprises a plurality of parameters including one or more of: cell related measurements, UE related measurements, mobility statistics, and random access channel statistics. The gNB is then configured to update gNB configuration to change periodicities of the common channel signals at least based on the monitored network performance metrics. Thus, the updated gNB configuration optimizes the energy saving gains without impacting the critical performance KPIs. Further, the dynamically changing periodicities of common channel signals in 5G NR allows the network to adapt to changing conditions and optimize performance in a data-driven manner.

A method for determining channel state information and a communication apparatus. The method includes: sending first indication information, where the first indication information indicates a position for sending a downlink reference signal; receiving channel statistics information, where the channel statistics information is determined based on the downlink reference signal; sending second indication information, where the second indication information indicates a position for sending an uplink reference signal; and receiving the uplink reference signal, and determining channel state information based on the uplink reference signal and the channel statistics information. According to the method, a terminal device sends the uplink reference signal based on an indication of a network device, and therefore a large quantity of time-frequency resources may not be occupied. Therefore, the terminal device is not required to have high calculation complexity.

This invention relates to an echo-assisted communication statistics modeling method, belonging to the field of wireless communication technology. The method of this invention proposes a way to predict the bistatic communication CCS (including communication path loss, delay spread, horizontal wave-off spread, pitch wave-off spread, horizontal wave-on spread, and pitch wave-on spread) from the monostatic sensing SCS (including sensed path loss, delay spread, horizontal wave-off spread, pitch wave-off spread, horizontal wave-on spread, and pitch wave-on spread) of an ISAC base station. This achieves complete and accurate prediction of communication channel statistics, solving the problem that existing ISAC channel modeling techniques cannot obtain large-scale link-level communication channel characteristics based on sensed data.
