Channel state information (CSI) can be used by a communications system to precondition transmissions between transmitter units and receiver units. In one aspect of the invention, disjoint sub-channel sets are assigned to transmit antennas located at a transmitter unit. Pilot symbols are generated and transmitted on a subset of the disjoint sub-channels. Upon receipt of the transmitted pilot symbols, the receiver units determine the CSI for the disjoint sub-channels that carried pilot symbols. These CSI values are reported to the transmitter unit, which will use these CSI values to generate CSI estimates for the disjoint sub-channels that did not carry pilot symbols. The amount of information necessary to report CSI on the reverse link can be further minimized through compression techniques and resource allocation techniques.

A method for asynchronously notifying an application client of a system or data event of interest within a database includes steps of receiving a subscription to an event name from a logical agent, the event name corresponding to the event of interest, and receiving a registration from the application client, the registration including delivery information indicating at least where and how a notification concerning the event is to be delivered. The occurrence of the event is then detected within the database, whereupon the notification of the detected event is published to a data structure referenced by the event name. The delivery information is then retrieved and the published notification is formatted according to the retrieved delivery information. The formatted notification is then asynchronously delivered to the application client over a network, such as the Internet. The application client may specify a rule, the satisfaction of which is a precondition to the delivery of the notification. The application client, in this manner, receives only the notification for which it has subscribed and receives the notifications substantially contemporaneously with the occurrence of the system or data event.

A system and method for enabling parallel replay of a backup memory log of client transaction request entries to a network storage appliance file system is provided. The backup memory is typically implemented as a non-volatile random access memory (NVRAM).

The swarm is transferred to the file system for parallel disk information-retrieval in an interleaved process. Any transactions that cannot be performed due to a required prerequisite action (e.g. a prior file-create) are returned to the initiator for reloading once the prerequisite action has occurred.

A method and apparatus for purging data from a middle cache level without purging the corresponding data from a lower cache level (i.e., a cache level closer to the processor using the data), and replacing the purged first data with other data of a different memory address than the purged first data, while leaving the data of the first cache line in the lower cache level. In some embodiments, in order to allow such mid-level purging, the first cache line must be in the "shared state" that allows reading of the data, but does not permit modifications to the data (i.e., modifications that would have to be written back to memory). If it is desired to modify the data, a directory facility will issue a purge to all caches of the shared-state data for that cache line, and then the processor that wants to modify the data will request an exclusive-state copy to be fetched to its lower-level cache and to all intervening levels of cache. Later, when the data in the lower cache level is modified, the modified data can be moved back to the original memory from the caches. In some embodiments, a purge of all shared-state copies of the first cache-line data from any and all caches having copies thereof is performed as a prerequisite to doing this exclusive-state fetch.
