Appl. No.:

11/196878

Inventors:

Yu Liu - Norcross GA, US
Jason James Rohr - Stone Mountain GA, US

Assignee:

American Megatrends, Inc. - Norcross GA

International Classification:

G06F 9/44
G06F 11/00
G06F 9/445
G06F 9/45

US Classification:

717124, 717127, 717129, 717131, 714 34, 714 381, 714 3814

Abstract:

A method, computer-readable medium, and apparatus for debugging a computer program utilizing breakpoints triggered by accessing a rarely used or unused I/O port is provided. Rarely used or unused I/O ports are identified in a computer system and a debugger program is instructed to halt program execution when an access is made to one or more of the identified ports. An instruction for writing to one of the ports is then inserted in the program to be debugged. When the instruction is executed, the debugger program will cause the execution of the program to stop. When the breakpoint is no longer needed, the debugger program is instructed not to halt when an access is made to the I/O port.

Abstract:

A method includes receiving, by a base station, a sounding reference signal (SRS) symbol from a user equipment (UE). The method also includes estimating, by the base station, an uplink (UL) channel from the UE to a full dimensional multiple-input multiple-output (FD-MIMO) base station base band based on the received SRS symbol. The method also includes receiving, by the base station from the UE, an estimate of a downlink (DL) channel from the FD-MIMO base station base band to the UE. The method also includes performing, by the base station, a joint calibration by applying one or more calibration algorithms using channel state information (CSI) of the UL channel and the DL channel.
