Predictive short-term channel quality reporting utilizing reference signals

An apparatus for wireless communication, comprising:

• a memory for storing instructions configured to provide shared reference signal (RS) allocation for interference mitigation in wireless communication;
• and
• a processor that executes modules for implementing the instructions, the modules comprising:
• an signal allocation module that identifies a data transmission scheduled for a first user equipment (a first UE) served by the apparatus and that generates an instruction for a second UE to measure a channel quality metric with respect to a pilot signal associated with the data transmission on a specified set of wireless resources;
• and
• a transmission module that sends a wireless message comprising the instruction to the second UE.

An apparatus for wireless communication, comprising:

• means for scheduling a data transmission for a first user equipment (a first UE) served by a cell of a wireless network on a set of time-frequency resources;
• means for transmitting a reference signal (a RS) configured at least in part for facilitating reception of the data transmission by the first UE;
• and
• means for instructing a second UE served by the cell to measure the RS and acquire a resource-specific metric of communication link quality for the set of time-frequency resources.

At least one processor configured for wireless communication, comprising:

• a first module that schedules a data transmission for a first user equipment (a first UE) served by a cell of a wireless network on a set of time-frequency resources;
• a second module that transmits a reference signal (a RS) configured at least in part for facilitating reception of the data transmission by the first UE;
• and
• a third module that instructs a second UE served by the cell to measure the RS and acquire a resource-specific metric of communication link quality for the set of time-frequency resources.

A computer program product, comprising:

• a computer-readable medium, comprising:
• a first set of codes for causing a computer to schedule a data transmission for a first user equipment (a first UE) served by a cell of a wireless network on a set of time-frequency resources;
• a second set of codes for causing the computer to transmit a reference signal (a RS) configured at least in part for facilitating reception of the data transmission by the first UE;
• and
• a third set of codes for causing the computer to send an instruction to a second UE served by the cell to measure the RS and acquire a resource-specific metric of communication link quality for the set of time-frequency resources.

An apparatus configured for wireless communication, comprising:

• a memory for storing instructions configured to provide short-term resource-specific interference reporting for wireless communication;
• and
• a data processor for executing modules to implement the instructions, the modules comprising:
• a decoding module that identifies a wireless message within a downlink transmission instructing a user equipment (a UE) associated with the apparatus to measure resource-specific interference to a pilot signal transmitted by a serving cell;
• and
• an analysis module that acquires information for identifying and decoding the pilot signal from the wireless message, and measures the resource-specific interference to the pilot signal with a time-based precision of substantially one subframe.

A computer program product, comprising:

• a computer-readable medium, comprising:
• a first set of codes for causing a computer to receive a wireless message that instructs a user equipment (a UE) to report interference to a UE-specific reference signal (a UE-RS) on a subset of time-frequency resources on which the UE-RS is transmitted, wherein the UE-RS is configured at least in part for a data transmission scheduled for a second UE;
• and
• a second set of codes for causing the computer to measure a level of interference to the UE-RS observed by the UE on the subset of time-frequency resources.
