Abstract: Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

Abstract: Techniques are provided for channel discovery. For example, there is provided a method operable by a mobile entity that may involve measuring beacon signals associated with the network. In one approach, the method may involve, in response to detecting an Authorized Shared Access (ASA) beacon signal on a frequency common to each network entity on a given ASA channel, extracting frequency information from the ASA beacon signal, wherein the ASA beacon signal comprises a single frequency network (SFN) beacon signal. In another approach, the method may involve, in response to detecting an ASA beacon signal on a frequency common to each network entity on a given ASA channel, extract frequency information from the ASA beacon signal, wherein timing correlates with an operating frequency for the ASA beacon signal.

Abstract: 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.

Abstract: 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.

Abstract: A method of wireless communication includes receiving by a single RF receiver of a user equipment (UE) a first portion of a downlink transmission from an eNode B (eNodeB) on a downlink primary carrier during at least one periodic subframe of the downlink primary carrier. The method also includes receiving by the single RF receiver a second portion of the downlink transmission from the eNodeB on the secondary downlink carrier. The reception occurs during a periodic sequence of subframes of the secondary downlink carrier following the at least one periodic subframe of the downlink primary carrier and before a second periodic subframe of the downlink primary carrier.
