Abstract: Instructions and logic interrupt and resume paging in secure enclaves. Embodiments include instructions, specify page addresses allocated to a secure enclave, the instructions are decoded for execution by a processor. The processor includes an enclave page cache to store secure data in a first cache line and in a last cache line for a page corresponding to the page address. A page state is read from the first or last cache line for the page when an entry in an enclave page cache mapping for the page indicates only a partial page is stored in the enclave page cache. The entry for a partial page may be set, and a new page state may be recorded in the first cache line when writing-back, or in the last cache line when loading the page when the instruction's execution is being interrupted. Thus the writing-back, or loading can be resumed.

Abstract: A noise and interference estimator and method for estimating noise and interference in a coordinated multipoint (CoMP) system at a mobile communication device is disclosed. The method comprises the operation of receiving a channel state information reference signal (CSI-RS) from a serving transmitting station at a user equipment (UE). Resource elements (REs) occupied by the CSI-RS of the serving transmitting station are muted on cooperating transmitting stations in the CoMP system. The operation of estimating a non-cooperating interference noise covariance matrix from the CSI-RS transmitted by the serving transmitting station follows.

Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.

The first UE may determine the requested feedback information and transmit the determined feedback information to the first base station. Thereafter, the first base station may reduce a transmission rank of ongoing transmissions to the UE based on the interference indication and the determined feedback information.
