Abstract: A network operator may synchronize access for wireless nodes (e.g., base stations) associated with the network operator. However, each network operator of a group of network operators may not synchronize access among the group. A lack of synchronization between network operators intending to utilize shared channels of a wireless communication system may result in a failure to utilize all available network resources. In some aspects, a device associated with a first network operator, of a plurality of network operators, may listen for communications associated with other network operators, of the plurality of network operators in a shared radio frequency spectrum band, during a set of intervals of a transmission opportunity of a channel for which the other network operators have a higher priority, and may communicate, using the channel, with a wireless node associated with the network operator based at least in part on the listening for communications.

Abstract: Certain aspects of the present disclosure provide techniques for MCS and/or rank selection for UE jointly served by BSs in a CoMP cluster. As described herein, MCS and/or rank selection may be based, at least in part, on the inter-cluster interference and intra-cluster interference experienced by the UE. According to aspects, a CoMP scheduler may assign a UE served by BSs in a CoMP cluster to one of a first group of UEs or a second group of UEs based, at least in part, on inter-cluster and intra-cluster interference experienced by the UE. The scheduler may assign at least one of a MCS or rank selection to the UE based, at least in part, on the assigned group. The scheduler may provide an indication, to one or more BSs in the CoMP cluster, of the at least one MCS or rank selection assigned to the UE.

Abstract: A method of wireless communication includes configuring a small cell with activation parameters. The activation parameters include a new carrier type having a reduced periodicity. The method also includes configuring a UE with time restricted measurements. The time restricted measurements correspond to the new carrier type and the reduced periodicity. The method further includes receiving small cell signal measurements from the UE and initiating an activation sequence in response to the small cell signal measurements.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus reduces inference in a received signal. The apparatus receives a signal including transmissions from a plurality of cells. The apparatus determines transmission parameter hypotheses associated with the plurality of cells. Each transmission parameter hypothesis from the transmission parameter hypotheses includes a set of transmission parameters associated with all the cells from the plurality cells. The apparatus selects at least one transmission parameter hypothesis based on a first metric applied to each hypothesis. The apparatus refines transmission parameters associated with at least one cell from the plurality of cells. The refining includes improving an accuracy of the transmission parameters associated with the at least one cell based on a second metric associated with each cell individually.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE determines an MCS that would facilitate interference suppression of an interfering first cell transmission from a first cell when decoding a second cell transmission from a second cell at the UE. The interfering first cell transmission is a transmission unintended for the UE. The second cell transmission is a transmission intended for the UE. The UE transmits information indicating the determined MCS for the first cell. The UE receives a transmission including the second cell transmission from the second cell and the interfering first cell transmission from the first cell. The UE demodulates and/or decodes the second cell transmission from the received transmission based on the determined MCS.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may perform one or more process that enable smart processing of resource elements from interfering base stations in order to improve cell decoding. The method includes prioritizing resource elements in order to reduce complexity of processing of the interfering resource elements. Some resource elements may be excluded from processing if priority is set to a null value or to a sufficiently low value. Resource elements in a subframe received from an interfering transmitter are grouped into one or more target regions and paired with serving and interfering cells. Each pairing is prioritized and processed in an order based on the priorities assigned to the pairings.
