    Abstract: Resource mapping and coding schemes to handle bursty interference are disclosed that provide for spreading the modulated symbols for one or more transmission code words over more symbols in the time-frequency transmission stream. Certain aspects allow for the modulated symbols to be based on bits from more than one code word. Other aspects also provide for re-mapping code word transmission sequences for re-transmissions based on the number of re-transmissions requested by the receiver. Additional aspects provide for layered coding that uses a lower fixed-size constellation to encode/decode transmissions in a layered manner in order to achieve a larger-size constellation encoding. The layered encoding process allows the transmitter and receiver to use different coding rates for each coding layer. The layered encoding process also allows interference from neighboring cells to be canceled without knowledge of the actual constellation used to code the interfering neighboring signal.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE identifies properties associated with reference signals of a received payload. The properties associated with reference signals of the received payload may include a reference signal structure and/or a traffic to pilot ratio. The UE determines a payload structure based on the identified properties. Subsequently, the UE decodes the received payload based on the determined payload structure. The UE may receive mapping information indicating a mapping between possible properties associated with reference signals and possible payload structures. The UE may determine the payload structure further based on the received mapping information. The UE may receive the mapping information through a broadcast or RRC signaling.

    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.

    Abstract: Techniques for wireless communications over a shared radio frequency spectrum band, may include techniques for transmitting uplink data transmissions using allocated uplink resources. Allocated uplink resources may include an uplink channel comprising a number of allocated interlaces of resource blocks (RBs) for use by a user equipment (UE). An incoming data stream may be processed and data separated into each of the allocated interlaces of RBs for the UE. Such separation may be through demultiplexing the data stream to obtain data for the allocated interlaces of RBs. The demultiplexed data may be mapped onto associated resource elements associated with the allocated interlaces of RBs, and transmitted. Different types of uplink channels, such as a physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) and/or a physical random access channel (PRACH) may be allocated to interlaces of RBs in one or more subframes of a transmitted radio frame.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may use a sampling rate that is less than a default sampling rate associated with a wireless carrier. The device may operate in a narrowband portion of a system bandwidth, and the sampling rate may be less than that used by devices monitoring the whole bandwidth. Multiple sampling rates may be used so that a portion of signal processing may be associated with one sampling rate and another portion of the signal processing may be associated with another sampling rate. The size of a cyclic prefix (CP) may be adjusted based on the sampling rate to align subframe timing boundaries for signals of different sampling rates. In some cases, each symbol of a signal may include both a CP and a postfix such that the postfix for each symbol overlaps the prefix of the next symbol.
