Abstract: Techniques for broadcast channel management on a shared communication medium are disclosed. An access terminal may be configured to identify a subframe number associated with a given subframe based not only on a subframe number indicator but also a reference boundary. Conversely, an access point may be configured to set a subframe number indicator for a given subframe based not only on its subframe number but also a reference boundary.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

Abstract: Methods and apparatuses for managing uplink scheduling for one or more user equipment served by a network entity in a wireless communications system are presented. For instance, an example method is presented that includes generating, by the network entity, an uplink bandwidth allocation map, the uplink bandwidth allocation map defining an uplink bandwidth allocation for at least one of the one or more user equipment for at least one of a plurality of uplink transmission window lengths. In addition, the example method includes transmitting the uplink bandwidth allocation map to at least one of the one or more user equipment.

Abstract: Techniques for transmitting acknowledgments on a shared communication medium are disclosed. In an aspect, an access terminal receives, from an access point, a plurality of downlink subframes on a downlink channel of the wireless communication medium, the plurality of downlink subframes carrying data for a plurality of processes. The access terminal transmits, to the access point, acknowledgments for the plurality of downlink subframes on an uplink subframe of an uplink channel of the wireless communication medium on one or more occasions, the uplink subframe including a plurality of bits, the plurality of bits corresponding to the plurality of downlink subframes or the plurality of processes.

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.

Abstract: A user equipment (UE) may be provisioned with multiple semi-persistent scheduling (SPS) configurations. The UE may determine a differentiation characteristic for determining which SPS configuration is indicated by a downlink control information or associated with a physical downlink shared channel (PDSCH). For example, the UE may receive a first activation of a first SPS configuration and a second activation of a second SPS configuration. The UE may determine the differentiation characteristic between the first SPS configuration and the second SPS configuration. The UE may determine that one of the first SPS configuration or the second SPS configuration is the SPS configuration for a received PDSCH based on the differentiation characteristic. The UE may transmit an acknowledgment of the PDSCH based on the determined SPS configuration.
