Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.

Abstract: Methods, systems, and devices are described for a UE to determine a DRX wakeup rule in an eICIC environment. A UE may identify a measurement period associated with reduced interference from one or more cells in a wireless communications network. The cells may be a serving cell or a neighbor cell. The measurement period may be identified based on eICIC data available to the UE. The eICIC data may be sent to the UE by a serving cell and/or determined by the UE. The UE may power up a wireless modem to perform a warm-up measurement of the serving cell during the identified measurement period prior to transitioning the UE to a DRX on state.

Abstract: In a wireless communication system, carrier aggregation may be used to provide desired amounts of bandwidth, where a primary carrier and one or more secondary carriers are aggregated. At the receive side of a system in which the aggregated carriers are in a single frequency band, an amplifier may be used to apply a common gain to the aggregated carriers in the single frequency band, and the common gain may be determined as a function of indications of received signal quality associated with groups of aggregated carriers containing one or more of the aggregated carriers, where one group contains the primary carrier and possible one or more secondary carriers and another group contains only secondary carriers.

Abstract: Various embodiments implemented on a mobile communication device leverage the availability of a plurality of coexistence mitigation strategies to choose a coexistence mitigation strategy that may be most successful in avoiding and/or mitigating coexistence interference between an aggressor RAT and a victim RAT. In response to determining that a coexistence event between the aggressor RAT and the victim RAT is occurring or is about to occur, a processor on the mobile communication device may determine various priority criteria related to the mobile communication device's current circumstances (e.g., network resources, device resources, etc.) and/or related to each available coexistence mitigation strategy. Using these determined priority criteria, the device processor may select and implement a coexistence mitigation strategy that may be the most suitable for avoiding/mitigating coexistence interference between the aggressor RAT and the victim RAT given the current condition, circumstances, etc. of the mobile communication device.

Abstract: A communication system comprises evolved base nodes (eNBs) communicating via an over-the-air (OTA) link with low mobility user equipment (UE). A network can utilize the eNBs for cooperative beam shaping for interference nulling based upon a number of factors UE (e.g., coordinated multi-point (CoMP) optimization for feedback, quality of service (QoS), fairness, etc.). The UE advantageously transmits multiple description coding (MDC) that supports a determination by the eNBs that coherent channel conditions (e.g., frequency and/or time invariance) exists for combining feedback reports to realize reduced quantization error. In addition, the MDC feedback reports still support incoherent channel states in which each report can be used individually for interference nulling/beamforming. MDC can be performed with one codebook or a plurality of codebooks.
