Abstract: Long term evolution (LTE)/LTE-Advanced (LTE-A) deployments with unlicensed spectrum leverage more efficient LTE communication aspects over unlicensed spectrum, such as over WIFI radio access technology. In order to accommodate such communications, various downlink procedures may be modified in order to handle communications between licensed and unlicensed spectrum with LTE/LTE-A deployments with unlicensed spectrum.

Abstract: Methods, systems, and apparatuses are described for wireless communications, in which transmission of common information to two or more receivers over unlicensed spectrum may be provided. The common information may be transmitted over a number (e.g., a set) of different carrier frequencies of the unlicensed spectrum. A staggering pattern may be employed to transmit all or a part of the common information across each of the carrier frequencies in the set of carrier frequencies. The detection of the information on one of the carrier frequencies may provide information that may be used to derive the staggering pattern. The duration of the common information transmission on each of the carrier frequencies may be selected such that a clear channel assessment (CCA) to determine availability of the unlicensed spectrum is not required.

Abstract: 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).

Abstract: Enhanced sounding reference signal (SRS) transmissions for multiple input, multiple output (MIMO) operation are disclosed in which a user equipment (UE) detects an observed interference level for each receiver chain of the UE. In response to an imbalance, the UE precodes a SRS targeting downlink operation to indicate the imbalance. The UE then transmits the precoded SRS. In alternative aspects, the precoded SRS vector may be determined by an evolved nodeB (eNB). In such aspects, the eNB determines the precoded SRS vector targeting downlink operations for the served UEs, wherein the determined precoded SRS vector includes determining the precoded SRS vector on a per UE basis, enabling the precoded SRS vector for either one or both of frequency division duplex (FDD) systems and time division duplex (TDD) systems, or enabling the precoded SRS vector for aperiodic SRS only. The eNB then transmits the determined precoded SRS vector to the UE.

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.
