    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: Methods, systems, and devices for wireless communication are described. A transmitting device, which may be configured without a radio link control (RLC) layer, may receive a packet data convergence protocol (PDCP) protocol data unit (PDU) at a media access control (MAC) layer. The device may then generate a set of transport blocks at the MAC layer using the PDCP PDU and transmit them over a wireless connection. A receiving device, which may also be configured without an RLC layer, may receive the transport blocks at the MAC layer, generate a MAC service data unit (SDU), and convey the MAC SDU to a PDCP. In some cases, the receiving device may then send an acknowledgement (ACK) or negative acknowledgement (NACK) for each transport block that includes a portion of the PDCP PDU, and the transmitting device may indicate to the PDCP layer whether the PDCP PDU was successfully received.

    Abstract: Techniques are described for wireless communication. A first method may include transmitting a reference signal from an access point over a shared spectrum to a user equipment (UE), and receiving a measurement of the reference signal from the UE. A second method may include receiving at a UE over a shared spectrum a reference signal from an access point, and transmitting a measurement of the reference signal to the access point. In each of the first and second methods, the measurement may indicate interference with the shared spectrum from outside of a clear channel assessment (CCA) range of the access point. A third method may include receiving a plurality of reference signal measurements, where each reference signal measurement corresponds to one of a plurality of access points and indicates interference with a shared spectrum from outside of a CCA range of the corresponding access point, and performing channel selection for the plurality of access points based at least in part on the received reference signal measurements.
