Abstract: Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.

Abstract: Techniques are described for managing QoS parameters of a bearer for which at least a portion of bearer data is served over a WLAN radio access technology. According to these techniques, a first device may identify a first set of one or more QoS parameters for serving a bearer over a wireless wide area network (WWAN). The first device may also determine a second set of one or more QoS parameters for serving the bearer over the WLAN based on an association between the first set of QoS parameters and the second set of one or more QoS parameters.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: A communication network element may send to a plurality of wireless devices a base radio link priority model that provides as an output a first prioritization of radio links. The wireless devices may generate trained radio link priority models using machine learning based on one or more attempts to establish a communication link with the communication network. The communication network element may receive trained radio link priority models from one or more wireless devices, update the base radio link priority model, and send to the wireless devices an updated base radio link priority model that provides as an output a second prioritization of radio links.

Abstract: A user equipment (UE) may operate in a reception mode that includes a set of sleep cycles and a set of wake cycles. During a sleep cycle of the UE, a signal quality of an active beam carrying a control channel or a data channel may degrade. This may result in the UE failing to decode the control channel or the data channel during a subsequent wake cycle. In some aspects, the UE may perform a measurement of one or more beams, of a set of beams, prior to the wake cycle. In some aspects, the UE may identify a beam, of the one or more beams, to use for communication with a base station (BS). In this way, the UE reduces a delay in data transfer associated with performing beam recovery after failing to decode the control channel or data channel during the wake cycle.

Abstract: The apparatus for wireless communication includes a processing system. The processing system is configured to establish a first radio link with a master base station, establish a second radio link with a first cell associated with a secondary base station, wherein the second radio link comprises a SRB, and receiving a RRC connection reconfiguration signal from the second radio link SRB to establish the second radio link with a second cell.

Abstract: Aspects described herein relate to communicating using multicast in a wireless network. A connection with an access point can be established using a cellular radio access technology. An internet protocol request for multicast communications can be transmitted to the access point over the connection. Multicast data can be received from the access point over resources corresponding to over-the-air multicast communications based on the internet protocol request.

Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.
