| 摘要 |
The present invention relates to an augmented data structure representing the availability of resources in a communication device, such as an augmented Bloom filter. A method of generating and using the augmented data structure comprises: providing first and additional groups of resources available in the same communication device; providing one or more hash functions for each of the first and additional groups, and calculating one or more hash values for each resource using the one or more corresponding hash functions; mapping each obtained hash value onto one entry of a data structure, wherein the hash values obtained from a resource of the first group are mapped onto a first subpart of the data structure only, such as a conventional Bloom array, and the hash values obtained from a resource of an additional group are mapped onto a portion of the data structure including the first subpart and an additional subpart. |
