Certain aspects of the present disclosure provide techniques and apparatuses for wireless communications. According to certain aspects, a set of protected resources, allocated to a base station of a first cell, that are protected by restricting transmissions of a second cell is determined and received power of a first reference signal from the base station in the set of resources is measured. According to certain aspects, a subset of one or more neighbor base stations that have reduced interference in a set of protected resources is determined and received power measurements for the subset of neighbor cells is excluded when calculating receive signal quality measurements for the subframe.
摘要:
Aspects of the present disclosure include a wireless system to reduce quantization error due to codebook-based PMI reporting by precoding channel state information reference signals (CSI-RSs) via a base station. The eNodeB varies the properties for a CSI-RS transmission in a known pattern and receives varying reports from the UE. The eNodeB can reconstruct the PMI with improved accuracy by combining multiple consecutive reports.

Certain aspects of the present disclosure provide techniques that may help improve performance in Coordinated Multi-Point networks that utilize coordinated transmissions, such as coordinated beamforming (CBF).

摘要:
Providing for a multipoint equalization (MPE) framework for coordinated multipoint (CoMP) transmission in wireless communication is described herein. The disclosed MPE framework involves distributed scheduling decisions for CoMP transmission, reducing complexity of scheduling coordination as compared with centralized scheduling techniques that coordinate scheduling decisions for multiple network base stations. Further, the MPE framework involves distributed computation of CoMP transmission coefficients, relying on a maximum of two backhaul hops to obtain information for the computation, and disseminate the transmission coefficients. The disclosed MPE framework shows substantial gains in various network deployments over conventional CoMP techniques.

A method, an apparatus, and a computer program product for wireless communication are provided in which an apparatus may determine broadcast channel scheduling information for one or more broadcasts of a payload by a broadcast channel associated with a first base station based on one or more broadcast channel interference coordination schemes, wherein reception of the broadcast channel associated with the first base station is interfered at least in part based on one or more transmissions from a second base station, and receive the payload based on the determined broadcast channel scheduling information.
摘要:
Various aspects of the present disclosure are directed to periodic over-the-air channel state information (CSI) reporting to serving cells and one or more non-serving cells via a control channel multi-point attachment. The channel state information report may be transmitted based on information indicating how to transmit the channel state information report to the non-serving cell. The information indicating how to transmit the channel state information report may be provided by the serving eNodeB. The information may include a periodicity, offset parameters, timing advance commands, power control commands, and/or an aperiodic report request.
