    Abstract: Power allocation for encoded bits in OFDM systems. OFDM symbol subcarriers may be allocated to a wireless user equipment (UE) device by a base station. A first portion of the allocated subcarriers may include systematic bits and a second portion of the allocated subcarriers may include parity bits according to a coding scheme. Transmit power may be unevenly allocated to the subcarriers allocated to the UE, such that subcarriers including systematic bits are allocated different power than the subcarriers including parity bits. The OFDM symbols including the subcarriers allocated to the UE may be transmitted to the UE by the base station according to the allocated power distribution.

    Abstract: This disclosure relates to using a dedicated reference subframes in a cellular communication system. According to one embodiment, a base station may transmit reference signals in a dedicated synchronization and measurement reference subframe. Neighboring base stations may also transmit reference signals in dedicated reference subframes in a temporally coordinated (synchronized) manner. The reference signals transmitted be each base station may be orthogonal with the reference signals transmitted by each neighboring base station. The reference subframes may be transmitted periodically, and data subframes may be transmitted between reference subframes. Some or all of the data subframes may not include cell-specific reference symbols, as their function may be unnecessary given the use of the dedicated reference subframes.

    Abstract: Manipulating modulation and coding scheme (MCS) allocation after a communication interruption. A UE device may resume communications with a BS after a communication interruption. First channel quality information may be generated and transmitted to the BS. A first MCS allocation, which may be based at least in part on the first channel quality information, may be received from the BS. Second channel quality information may be generated and transmitted to the BS, where the second channel quality information is modified by an offset configured to modify a second MCS allocation.

    Abstract: Selecting a physical channel for cellular communication based on application traffic pattern. A radio bearer may be established between a wireless device and a base station. A physical downlink channel may be selected for the radio bearer. The physical downlink channel may be selected based on an application traffic pattern of an application associated with the radio bearer. In some instances, a physical uplink channel may also be selected based on an application traffic pattern of an application associated with the radio bearer.

    Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.
