Abstract: Methods, systems, and devices for wireless communications are described. Techniques for multiple transmission reception points (TRPs) in a cluster may coordinate scheduling and communications with a user equipment (UE). Different TRPs may allocate uplink resources for one or more UEs within a coordinated cluster to transmit feedback information. A first TRP may provide a first set of resources that one or more associated UEs may use to transmit acknowledgment (ACK) feedback to indicate successful receipt of a downlink transmission of the first TRP, and one or more other TRPs of the coordinated cluster may provide a second set of resources that the one or more UEs may use to transmit negative acknowledgment (NACK) feedback to indicate that a downlink transmission of the first TRP was lost. The second set of resources may include non-orthogonal multiple access (NOMA) resources.

Abstract: A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

Abstract: Techniques for femtocell message delivery and network planning are described herein. A mobile device sends a registration request to an access point, such as a femtocell access point. If denied registration, the mobile device may return to service by a macro cell access point. A network entity, such as a femtocell gateway serving the access point, may determine an identification of the mobile device. The network entity may send the identification of mobile device and an identifier of the access point to an application server. The application server may create and send a targeted message to the mobile device based on the identification of mobile device and the identifier of the access point. The application server may determine a user count for the access point and facilitate network planning based on the user count.

Abstract: A small cell (e.g., femtocell) in a wireless communication may determine a set of wireless signal measurements for a plurality of small cells causing pilot cell pollution within a coverage area. The small cell may determine an adjustment of a transmission parameter of the small cells for reducing the pilot cell pollution, and transmit the adjustment to the small cells. The adjustment may include, for example, minimizing an area of overlap between at least two small cells having signal power difference below a threshold, maximizing a signal to interference and noise ratio at a location associated with at least two small cells, minimizing an area associated with at least two pilot signals within a threshold signal level, distributing traffic load to at least two of the small cells based on the set of measurements, or by minimizing the number of small cells covering a path.

Abstract: Many environments or operational conditions create repetitive radio frequency (RF) interference conditions resulting from repetitive mechanical or electrical activity. This activity may create oscillations in the RF conditions between an MTC UE and a serving base station. Aspects of the present invention are directed to improving data efficiency and battery life by optimizing communication based on a detected periodicity of repetitive mechanical or electrical activity at the UE by monitoring the oscillations of at least one RF condition between the MTC UE and the base station, and scheduling communication between the UE and the network during periods associated with favorable radio conditions.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Applying the one or more filters may include applying an UL RSSI filter to the one or more femto nodes to determine whether presence of the device causes a rise in UL RSSI measured at the one or more femto nodes.

Abstract: The present disclosure generally relates to techniques to increase reliability of communications within a network during a low reliability period. The network may include a user equipment (UE) communicatively coupled with one or more transmit/receive points (TRPs), with the communications between the UE and the one more TRPs requiring a reliability above a first reliability threshold. A processor of a network entity may identify a low reliability period which occurs when the reliability of the communications is determined to be below a second reliability threshold. The processor may cause the network to perform one or more remedial actions to increase the reliability during the low reliability period.

Abstract: Various aspects and features related to wireless communication for high reliability and low latency are described. In an aspect of the disclosure, a method, a computer-readable medium, a system, and an apparatus are provided. A method of wireless communication includes communicating with a network via one or more network nodes using separate wireless links for each UE in a set of UEs using a same RAT. The method includes either transmitting uplink data traffic from a common source to the network nodes using respective separate wireless links corresponding to the two or more UEs or receiving downlink data traffic destined for the common source from the network nodes using respective separate wireless links corresponding to the two or more UE.
