摘要： Certain aspects of the present disclosure provide various mechanisms that allow a user equipment to convey information regarding one or more attributes to a base station during a random access (RA) procedure. The attributes may include, for example a capability of the UE (e.g., to support a particular feature or version of a standard) or a condition of the UE (e.g., if it is currently experiencing an interference condition).

摘要： Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

摘要： A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.
