LTE hierarchical burst mode
First Claim
1. A method for wireless communication, comprising:
- identifying, within a radio frame, a first subframe that comprises a first number of orthogonal frequency division multiplexing (OFDM) symbols and a second subframe that comprises a second number of OFDM symbols that is different from the first number of OFDM symbols, wherein each of the OFDM symbols in the first subframe have a first symbol duration and each of the OFDM symbols in the second subframe have a second symbol duration that is different than the first symbol duration;
determining that the first number of OFDM symbols of the first subframe of the radio frame is configured for communication in a first link direction;
communicating in the first link direction during the first subframe of the radio frame using one or more of the first number of OFDM symbols; and
communicating, during the second subframe of the radio frame using one or more of the second number of OFDM symbols, in the first link direction or a second link direction that is different from the first link direction.

Abstract
Methods, systems, and devices are described for hierarchical communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing.
