摘要： Provided are a method for determining multi-user channel quality in a mobile communication system, a user terminal and a base station of the present invention. The method includes: in each user terminal, calculating the MU CQIs based on a first feedback template notified from a base station that has control over the user terminal or a second feedback template set by the user terminal and feeding the MU CQIs back to the base station. In the first feedback template or the second feedback template, a feedback ratio of MU CQIs for a plurality of hypothetical interference numbers k are defined, k being an integer larger than 0 and smaller than a maximum number of users schedulable by the base station. According to the present invention, it is possible to improve the accuracy in multi-user MIMO scheduling.

摘要： A respiratory mask assembly (10), adapted to be placed over the nose and mouth of the face of a wearer. The mask assembly includes a base mask (12), defining a set of openings; a filter (30), detachably supported by the base mask and covering the openings; and a source of electricity (60). Also, an air exit valve (34) is positioned over one of the openings of the base mask and releases air from inside the mask to the outside when pressure inside is greater than air pressure outside. Finally, a centrifugal fan (22) is electrically connected to the source of electricity and is positioned in one of the openings of the base mask so as to draw air through the filter to the inside. This fan blows air into the inside in a direction that misses the wearer's face.

摘要： A searchable web site discovery and recommendation system and method for discovering and recommending searchable web sites to a user of a search engine. In general, given a search query by a user embodiments of the system and method discover and then recommend a list of searchable web sites. Embodiments of the system and method discover and recommend searchable web sites using client-side query behavior logs. A set of descriptive features is automatically extracted from the logs. In addition, embodiments of the system and method expand the initial search query by submitting the query to a general search engine and leveraging snippets from the search engine results. Embodiments of the system and method model a conditional probability of a searchable web site based on four components and the extracted descriptive features. A ranked list of recommended searchable web sites is obtained from the conditional probability and displayed to a user.
