Uplink channel quality measurement using a subframe with high-intensity reference signal bursts

A method of wireless communication operable at a scheduling entity, comprising:

• communicating with a subordinate entity utilizing a plurality of self-contained subframes comprising a first subframe and a second subframe, each of the self-contained subframes comprising an uplink (UL) portion and a downlink (DL) portion;
• transmitting DL control information to the subordinate entity in the DL portion of the first subframe, the subordinate entity waking up from a discontinuous reception (DRX) off mode in the first subframe;
• receiving first UL data comprising a wake-up burst structure including a plurality of reference signal bursts from the subordinate entity in the UL portion of the first subframe, wherein the plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe;
• and
• receiving second UL data comprising a nominal number of reference signal bursts from the scheduled entity in the UL portion of the second subframe, wherein the wake-up burst structure comprises a greater number of reference signal bursts than the nominal number of reference signal bursts.

An apparatus for wireless communication, comprising:

• a communication interface configured to communicate with a scheduling entity;
• a memory comprising executable code;
• and
• a processor operatively coupled to the communication interface and the memory,
• wherein the processor is configured by the executable code to:
• communicate with the scheduling entity utilizing a plurality of self-contained subframes comprising a first subframe and a second subframe, each of the self-contained subframes comprising an uplink (UL) portion and a downlink (DL) portion;
• wake up from a discontinuous reception (DRX) off mode to receive DL control information from the scheduling entity in the DL portion of the first subframe;
• transmit first UL data comprising a wake-up burst structure including a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe, wherein the plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe;
• and
• transmit second UL data comprising the nominal number of reference signal bursts to the scheduling entity in the UL portion of the second subframe, wherein the wake-up burst structure comprises a greater number of reference signal bursts than the nominal number of reference signal bursts.
