Obscuring internet searches from external web service providers
Approaches presented herein enable obscuring a query from an external web service provider. More specifically, a user-submitted query is split into at least two non-identical, secondary search queries. The non-identical search queries are submitted to an external web services provider separately, at different times spread throughout a search timeframe, from different virtual locations, thereby obscuring the original search query from the external web services provider. An internal system receives and merges the search results of the non-identical secondary queries from the external web services provider. The internal system then performs a second search on the merged results using the original user-submitted search query to find the results within the merged results that are most relevant to the original query. These relevant results are then presented to the user. |

Methods to signal current MIMO RX antenna configuration status
In MIMO wireless communication networks, receiver MIMO antenna parameters are not static over time. For example, the MIMO channel correlation is higher for high frequency bands than for low frequency bands. This variability of the receiver antenna parameters introduces uncertainty based the reported CSI (e.g., CQI, PMI, RI) if the network uses only static assumptions for such antenna parameter values. In embodiments, the UE determines the current status of its receive antenna parameters—such as number, configuration, correlation, and power imbalance—and transmits this information to the network (e.g., serving BS). The network node then based on the received information performs one or more radio operational tasks leading to more efficient use of radio resources and enhanced system performance. |
