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.

Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: Aspects of the present disclosure provide techniques and apparatus for power savings for control channel monitoring for enhanced machine type communications (eMTC). In one aspect, a method is provided which may be performed by a wireless device such as a low cost wireless device, which may be user equipment (UE) or an eMTC UE. The method generally includes determining whether a downlink channel is present in a subframe; and causing the UE to enter a low power mode for a duration based on a determination that the downlink channel is not present in the subframe.

A method is provided for wireless communications by a user equipment (UE). The method generally includes detecting a synchronization signal transmitted from at least one of a plurality of transmission points, wherein each of the plurality of transmission points transmits a synchronization signal at a different offset time relative to a subframe boundary in a synchronized network, determining a subframe occurring a fixed time after detecting the synchronization signal to monitor for system information transmitted from at least one of the plurality of transmission points, and monitoring for a system information block during the determined subframe.
