Abstract: Certain aspects of the present disclosure propose methods and apparatus to transmit information about number of active UEs in a cell (e.g., pico cell) that need protection to an interfering cell (e.g., a macro cell). The information may be transmitted in a resource status update message. The active users may be defined as users whose downlink performance and/or quality of service are limited by the available number of protected resources.

Abstract: Certain aspects of the present disclosure relate to techniques for backhaul enhancements for cooperative multi-point (CoMP) operations. An aggressor node may take pre-scheduling decisions in advance of beamformed data transmissions based on the pre-scheduling decisions. The aggressor node may communicate the pre-scheduling decisions to one or more victim nodes, for example, via a backhaul link between the aggressor node and the one or more victim nodes. A victim node may take scheduling decisions based at least on the pre-scheduling decisions of the aggressor node to coordinate beamformed transmissions from the victim node with the beamformed transmissions from the aggressor node.

Abstract: According to certain aspects, techniques for aperiodically reporting channel state information (CSI) on protected and unprotected resources are provided. The protected resources may include resources in which transmissions in a first cell are protected by restricting transmissions in a second cell. According to certain aspects, a request for channel quality indicator (CQI) may be sent in a first subframe, CQI may be measured for a second subframe having a first offset from the first subframe, and a corresponding CQI report sent in a third subframe having a second offset from the first subframe.

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: Methods and apparatuses are provided that include determining resources over which to measure signals from a base station. One or more parameters related to a resource restriction pattern can be provided to the device for measuring signals over indicated resources. The resource restricted pattern can correspond to a bitmap where each bit relates to a time period over which signals can be transmitted by the base station, and the bit can specify whether a signal received over the resource should be measured. The resource restriction pattern can correspond to a set or protected resources negotiated using a resource partitioning scheme.

Abstract: There lies a challenge to develop a technique of accurately and efficiently determining an available communication channel. In accordance with some embodiments disclosed herein, techniques for sensing a primary user of a particular communication channel are performed more efficiently. In some implementations, a geo-location of a communication device is combined with a sensing algorithm in order to more efficiently perform spectrum sensing. In some implementations, a geo-location and an accuracy determination may be used to determine all required sample regions in order to ensure that a primary user is not present in a particular location.
