Abstract

Methods, systems, and devices are described for hierarchical communications and low latency support 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. In some examples symbols of different duration may be multiplexed such that different symbol durations coexist.

First claim

What is claimed is:

1 . A method for communications within a wireless communications system, comprising:
configuring to operate within the wireless communications system, wherein the wireless communications system is partially defined through a first layer, wherein first layer transmissions have a first subframe type having a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission; and operating at a second layer multiplexed with the first layer, wherein second layer transmissions have a second subframe type having a second RTT that is less than the first RTT.

2 . A method for communications in a wireless communications system, comprising:
concurrently transmitting, in a frame, one or more subframes having a first subframe type using two or more separate carriers, at least one of the carriers having a first bandwidth; and transmitting, in the frame, a subframe of a second subframe type using at least one carrier having a second bandwidth, the second bandwidth being greater than the first bandwidth.

3 . A method of wireless communication, comprising:
identifying a first region of a carrier, the first region having a first symbol duration; identifying a second region of the carrier, the second region having a second symbol duration different from the first symbol duration, wherein the first and second regions are time-division multiplexed (TDM) or frequency-division multiplexed (FDM); and communicating with a base station using the first or second region based at least in part on a latency requirement.
