Puncture recovery and resource reclaiming for multi-priority scheduling

A method for wireless communication, comprising:

• receiving, from a base station, a downlink allocation for a first service during a first transmission time interval (TTI);
• determining that a priority indication channel is to be monitored on a periodic basis that corresponds to a second TTI duration of a second service, the second TTI duration being shorter than the first TTI;
• receiving a first transmission of the first service during the first TTI;
• determining that the priority indication channel indicates that the first transmission is being punctured by a second transmission of the second service, a first punctured portion of the first TTI having a duration corresponding to the second TTI duration;
• discarding transmissions received during the first punctured portion of the first TTI;
• and
• receiving the first punctured portion of the first transmission during a subsequent portion of the first TTI, wherein the first punctured portion of the first transmission is received during the subsequent portion of the first TTI concurrently with a second portion of the first transmission that is received in the subsequent portion of the first TTI.

An apparatus for wireless communication, comprising:

• means for identifying a first service for transmission of first service data to a UE during a first transmission time interval (TTI);
• means for identifying a second service having a second TTI that is shorter than the first TTI for transmitting second service data;
• means for transmitting a first transmission of the first service to the UE during the first TTI;
• means for puncturing a first portion of the first transmission with a second transmission of the second service, a duration of the first portion corresponding to the second TTI;
• and
• means for transmitting the first portion of the first transmission to the UE during a subsequent portion of the first TTI, wherein the means for transmitting the first portion of the first transmission during the subsequent portion of the first TTI comprise means for transmitting the first portion of the first transmission during the subsequent portion of the first TTI concurrently with a second portion of the first transmission transmitted in the subsequent portion of the first TTI.
