    Abstract: Methods, systems, and devices are described for reconfiguring a user equipment (UE) to operate in a reconfigured TDD UL-DL configuration. An initial uplink-downlink (UL-DL) configuration for TDD communication may be provided for communication between an e Node B and a UE. One or more subframes within each frame transmitted using the initial UL-DL configuration may be identified as flexible subframes. The identification of flexible subframes may permit the identification of timing for HARQ transmissions that does not change when a reconfiguration takes place. A different UL-DL configuration may be transmitted to the UE, in which at least one flexible subframe is to be changed from an uplink subframe to a downlink subframe. The different UL-DL configuration may be transmitted by, for example, a pseudo-uplink grant to the UE, which indicates that the UE is to reconfigure one or more flexible subframes from uplink to downlink transmission.

    Abstract: Interference mitigation solutions are disclosed for interference experienced based on asymmetric uplink (UL)/downlink (DL) slot configuration. The aggressor/victim network entities are identified using either measurement or static/semi-static means, such that the victim network entities that may be impacted by interference from aggressor network entity transmissions are identified. Inter Cell Interference Coordination (ICIC) mechanisms are extended to negotiate and address scheduling that intelligently mitigates interference that occurs in the colliding slots.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for flexible resource mapping and modulation and coding scheme (MCS) determination in wireless communication systems. According to certain aspects, a method for wireless communications that may be performed by a transmitter is provided. The method generally includes determining MCSs to use for each of multiple portions of a transport block and transmitting the portions of the transport block according to the determined MCSs to a wireless node. Flexible MCS and resource mapping determination may improve demodulation performance for code blocks that are far from pilots.

    Abstract: Techniques are described for wireless communications at a user equipment (UE). One method includes determining a first cell identifier (ID) associated with a first downlink transmission in a first radio frequency spectrum band of paired radio frequency spectrum bands, determining a second cell ID associated with a second downlink transmission in a second radio frequency spectrum band of the paired radio frequency spectrum bands, and communicating based on the first cell ID and the second cell ID. In some cases, the method may include determining a cell ID associated with a downlink transmission in an uplink radio frequency spectrum band, and receiving the downlink transmission in a subframe of the uplink radio frequency spectrum band. The downlink transmission may be based on the cell ID and a format of a physical uplink shared channel (PUSCH), and may include an eight layer single-user multiple-input multiple-output (SU-MIMO) transmission.
