摘要： A method for establishing an encrypted communication channel is described. Query IDs are generated at a first device. Each query ID identifies a keyword in a set of keywords. Query IDs are received, at a second device. A second set of keywords is determined by the second device based on the query IDs. Match IDs are determined based on the second set. Each match ID identifies a keyword in the second set. An encryption key is generated based on the second set. A response is sent which includes the match IDs and an encrypted message. At the first device, the second set is determined based on the match IDs. The second set includes keywords of the first set of keywords identified by the match IDs. The encryption key is generated at the first device and the encrypted message is decrypted. Apparatus and computer readable media are also described.

摘要： The invention relates to the design of power sequences for use in a group of sub-areas of a wireless communication system. Each power sequence defines for one of the sub-areas transmission power values for transmissions using a respective one of a plurality of medium access units. For each of the sub-areas of the group, reception quality values are determined for transmissions between an access station serving the sub-area and mobile stations located at an edge of the sub-area. The reception quality values allow meeting system. The reception quality values are then converted for each of the sub-areas into transmission power values of a power sequence.

摘要： A system for facilitating communal apparatus interaction. In accordance with at least one embodiment of the present invention, an apparatus configured to communicate on a wireless channel may receive first information pertaining to wireless traffic expected from other networks also utilizing the wireless channel. The apparatus may then determine whether the received information satisfies a first criterion, and if it is determined that the first information satisfies the first criterion, the apparatus may shorten an awake window duration for communicating on the wireless channel. Alternatively, if it is determined that the information does not satisfy the first criterion, the apparatus may proceed to further determine whether second information pertaining to wireless traffic on the wireless channel that is expected from a network satisfies a second criterion. If it is determined that the second information satisfies the second criterion, the apparatus may proceed to lengthen the awake window duration.
