摘要： Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting data on a second physical channel that can be reliably received at a second minimum SNR that is lower than the first minimum SNR. In another aspect, low SNR operation may be supported by transmitting data on both the first and second physical channels. In yet another aspect, low SNR operation may be supported by transmitting data in multiple instances of the first and/or second physical channel. In yet another aspect, low power operation may be supported by transmitting the second physical channel in a portion of the system bandwidth instead of across the entire system bandwidth.

摘要： Techniques for managing interference in a wireless communication system are disclosed. In one aspect, one or more frequencies are identified, where transmission by a user equipment (UE) on the one or more frequencies would interfere with reception at the UE. An indication is transmitted to a base station which comprises frequency location information based on the one or more frequencies. Additionally, the UE can receive an assignment of frequency resources from the based station based on the indication.

摘要： 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.

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.

摘要： 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.
