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 they different symbol durations coexist.

Dependent claims

A method of wireless communication, comprising:

configuring a single frame structure of a single carrier with a first region having a first symbol duration and a second region having a second symbol duration different from the first symbol duration, wherein the first and second regions of the single frame structure of the single carrier are time-division multiplexed (TDM) or frequency-division multiplexed (FDM), wherein the first region includes a control channel and a shared channel, and the second region includes a control channel and a shared channel, and wherein the second region includes both downlink symbols and uplink symbols, and wherein the second symbol duration is configurable;
and
communicating with a user equipment (UE) using the first or second region of the single frame structure of the single carrier.

An apparatus for wireless communication, comprising:

a processor;
memory in electronic communication with the processor;
and
instructions stored in the memory, the instructions executable by the processor to cause the apparatus to:
identify a first region of a single frame structure of a single carrier, the first region having a first symbol duration;
identify a second region of the single frame structure of the single carrier, the second region having a second symbol duration different from the first symbol duration, wherein the first and second regions of the single frame structure of the single carrier are time-division multiplexed (TDM) or frequency-division multiplexed (FDM), wherein the first region includes a control channel and a shared channel, and the second region includes a control channel and a shared channel, and wherein the second region includes both downlink symbols and uplink symbols, and wherein the second symbol duration is configurable;
and
communicate with a base station using the first or second region of the single frame structure of the single carrier.
