Abstract: A method for mitigating interference in a wireless network includes an eNodeB and/or a UE identifying interference. The eNodeB may identify the interfering TDD configurations based on a downlink signal of a neighboring eNodeB received during an uplink timeslot for a UE associated with the eNodeB. Likewise, the UE may identify an interfering UE based on an uplink signal received during a downlink timeslot for an eNodeB associated with the UE. The eNodeB performs interference management based at least in part on the identified interference.

Abstract: A method of wireless communication includes determining a capability for a number of channel state information configurations supported by a user equipment (UE). The channel state information processes link a channel measurement report with an interference measurement report. The UE transmits the capability to an eNodeB. Additionally, the UE receives CSI process configurations. The CSI process configurations identify CSI processes that can be requested by the eNodeB.

Abstract: Techniques for computing and reporting channel quality indication (CQI) are described. In an aspect, a plurality of CQI computation methods may be supported, and each CQI computation method may indicate how CQI should be computed. One CQI computation method may be selected for use. CQI may then be computed and reported in accordance with the selected CQI computation method.

Abstract: Certain aspects of the present disclosure relate to techniques for reducing the decoding complexity for low cost devices (e.g., low cost UEs). One technique may include simplifying the PDCCH format. This may include generating a compact DCI format for transmitting DCI to a low cost device. The compact DCI format may correspond to at least one standard DCI format used by a regular UE and may comprise a reduced number of bits when compared to the standard DCI format. Another technique may include reducing the number of blind decodes. This technique may include selecting a set of resources for transmitting DCI from a limited set of decoding candidates, such that a receiving low cost device need only perform blind decodes for the limited set of decoding candidates.

Abstract translation: 本公开的某些方面涉及用于降低低成本设备（例如低成本UE）的解码复杂度的技术。 一种技术可以包括简化PDCCH格式。 这可以包括生成用于将DCI发送到低成本设备的紧凑DCI格式。 紧凑的DCI格式可以对应于常规UE使用的至少一种标准DCI格式，并且与标准DCI格式相比可以包括减少的比特数。 另一技术可以包括减少盲解码的数量。 该技术可以包括从有限的一组解码候选中选择用于发送DCI的资源集合，使得接收低成本设备仅需要对有限的解码候选集进行盲解码。
