Dynamic power adjustment for small cells

A radio node may transmit a signal using a transmit power. Then, the radio node may adjust the transmit power within a range of values. The adjustment may include reducing the transmit power when a spatial received signal strength indication (RSSI) metric of the radio node is greater than a first threshold value and a coverage criterion is met. Note that the spatial RSSI metric of the radio node may correspond to a set of temporal RSSI metrics of the radio node received from neighboring radio nodes. Moreover, the coverage criterion may be that less than a portion of RSSI measurements of the radio node associated with electronic devices, which are communicatively attached with the radio node, is less than a second threshold value. Alternatively, the adjustment may include increasing the transmit power when the spatial RSSI metric is less than the first threshold value.

System and Method for Phase Noise Reduction in Very High Frequency Spectrum

Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.
