Abstract
Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the subset of subframes.

A method for wireless communications by a user equipment (UE), comprising:
- identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH), wherein the subset of subframes comprises different subframes for different types of PDSCH transmissions;
- identifying a signal configured to be transmitted in one or more subframes in the subset of subframes;
- determining whether to monitor for the signal in the one or more subframes;
- and
- receiving the data on the PDSCH in the subset of subframes.
A method for wireless communications by a base station (BS), comprising:
- identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH), wherein the subset of subframes comprises different subframes for different types of PDSCH transmissions;
- identifying a signal configured to be transmitted in one or more subframes in the subset of subframes;
- determining whether to drop the signal in the one or more subframes;
- and
- transmitting the data on the PDSCH in the subset of subframes.
