Common network resource allocation for matching data
In some implementations, a radio access provider (RAP), e.g., of a wireless telecommunications network, can identifying matching data in two data flows associated with respective, different terminals. The RAP can determine a common wireless-resource allocation for the matching data, and respective allocation messages for the terminals. Each allocation message can indicate the common resource allocation. The RAP can transmit the allocation messages to the terminals. In some implementations, a wireless communications device can receive two allocation messages, one for a common and one for a terminal-specific resource allocation. The device can receive the common-allocation data before the terminal-specific data, and assemble a packet with at least some of the terminal-specific data before some of the common-allocation data. The device can decrypt the common-allocation data using a key associated with the common allocation.
