  • Patent number: 9774424
    Abstract: Transmission of random access preamble structures within a cellular wireless network is based on the use of cyclic shifted constant amplitude zero autocorrelation (“CAZAC”) sequences to generate the random access preamble signal. A pre-defined set of sequences is arranged in a specific order. Within the predefined set of sequences is an ordered group of sequences that is a proper subset of the pre-defined set of sequences. Within a given cell, up to 64 sequences may need to be signaled. In order to minimize the associated overhead due to signaling multiple sequences, only one logical index is transmitted by a base station serving the cell and a user equipment within the cell derives the subsequent indexes according to the pre-defined ordering. Each sequence has a unique logical index. The ordering of sequences is identified by the logical indexes of the sequences, with each logical index uniquely mapped to a generating index.

  • Patent number: 9762518
    Abstract: Various embodiments provide session-based filtering to filter messages in a cooperative manner between a client and a service provider. In at least some embodiments, a service provider can establish a messaging session with a client and deliver messages to the client. The client can implement various client-side techniques to filter some of the messages based on various client designated criteria. The service provider can obtain feedback from the client indicative of one or more of the delivered messages that have been filtered. The service provider can dynamically create a session-based list based on the feedback and use the list during the session to block messages on the server-side according to the client designated criteria. When the session concludes, the session-based list can be discarded. In this manner, message filtering can occur without persistent storage of state data for the filtering at the service provider.
