摘要： Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). Resource coordination/partitioning may be performed to allocate resources to a serving Node B located near the vicinity of a strong interfering Node B. The interfering Node B may avoid transmitting on the allocated/protected resources, possibly except for a common reference signal (CRS). A UE can then communicate with the serving Node B on the protected resources in the presence of the interfering Node B and may observe no interference (possibly except for the CRS) from the interfering Node B. When CRS tones of an interferer may collide with control/data tones of a serving cell, CRS interference cancellation (CRS IC) or puncturing of interfered resource elements (REs) may be appropriate. Certain aspects of the present disclosure provide techniques, where the UE may dynamically switch between CRS IC and RE puncturing based on certain parameters.

摘要： Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). According to certain aspects of ICIC, resource coordination/partitioning may be performed to allocate resources to a serving Node B located near the vicinity of a strong interfering Node B. The interfering Node B may avoid transmitting on the allocated/protected resources, but transmissions from the interfering Node B on resources not allocated to the serving Node B (i.e., unprotected) may cause significant interference on cell-specific reference signal (CRS) tones of the serving Node B. Therefore, if the CRS tones of the unallocated/unprotected resources are used, performance degradation may result to various operations of the serving Node B. Therefore, certain aspects of the present disclosure provide techniques for a UE receiver in utilizing resource partitioning information (RPI) for performing CRS processing in a heterogeneous network (HetNet).

摘要： Techniques for reporting channel information are described. In one aspect, a plurality of channel information reporting modes are available to a user equipment (UE) for reporting channel information for coordinated multi-point (CoMP) data transmission.

The UE may also determine a second channel information reporting mode to use, determine second channel information related to multiple cells in the CoMP measurement set, and send the second channel information in accordance with the second channel information reporting mode. A plurality of channel feedback configurations may be supported, including a single-stage, a two-stage, and/or a one-shot channel configurations.

摘要： In a wireless communication system, interference on data tones is estimated by detecting data transmissions from interferers. An overall interference covariance matrix is estimated as a function of scalar traffic to pilot ratio (TPR) estimates, residual interference covariance estimates, and covariance of channel estimates of dominant interferers. The interference estimates are refined as a function of reliability based on a ratio of power received from a serving cell and power received from a dominant interferer.

摘要： Interference on pilot signals and on data tones can be mismatched. Different types of interference estimates perform differently based on how the mismatch occurs. The resulting interference estimate may thus be inaccurate. Interference estimates based on pilot signals and also on data tones can both be evaluated for reliability. The more reliable of the two can then be selected. If the data tones estimate is selected, the estimate can be calculated from covariance matrices or from traffic-to-pilot ratios.

摘要： Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.
