Abstract: Techniques for prioritizing user equipments (UEs) for switching between wireless systems are disclosed. The wireless systems may be part of a small cell and may include a WLAN system and a cellular system. In one design, a network entity (e.g., the small cell) may identify a plurality of UEs communicating with a first wireless system. The first wireless system may be one of a plurality of wireless systems providing communication coverage for the UEs. The network entity may determine priorities of the UEs for switching from the first wireless system to a second wireless system. The network entity may then select at least one UE among the plurality of UEs to switch from the first wireless system to the second wireless system based on the priorities of the UEs.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A multi-radio device controls wireless communications by identifying one or more connection points between radio(s) of the multi-radio device and an operating system executing on a host device, analyzing a policy relating to the multi-radio device, and exposing, to the operating system, a subset of the connection points based on the policy. A modem manages a connection to an applications processor (AP) by virtualizing physical communication interfaces at the modem, providing a single Internet protocol (IP) interface representing the virtualized physical communication interfaces to a high level operating system (HLOS) at the AP, detecting a physical communication interface connected to the modem, and determining whether to expose the detected physical communication interface to the HLOS as a standalone virtualized physical communication interface, or hide the detected physical communication interface as part of an existing virtualized physical communication interface.

Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

Abstract: Methods, systems, and devices are described for managing a radio connection between a mobile device and a base station of a radio access network. A determination is made that the mobile device is in a standby state. The radio connection transitions to a high power state while the mobile device is in the standby state. A net number of transport layer connections for the mobile device are identified. The transport layer connections are Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) sockets. A net count of transport layer connections opened and closed while the radio connection is in the high power state is calculated. Dormancy of the radio connection is initiated when the mobile device is in the standby state, based at least in part on the calculated net count of transport layer connections.

Abstract: Techniques for aggregating heterogeneous carriers in a wireless communication system are disclosed. A mobile device may receive a configuration for aggregating a plurality of component carriers including one or more cellular carriers and a wireless local area network (WLAN) carrier. The one or more cellular carriers may include LTE carriers, and aggregation may be performed at a sub-IP protocol layer of operation. In one aspect, protocol entities may be modified to perform quality of service determinations, carrier selection, traffic mapping, or the like, in view of the different capabilities and characteristics of the heterogeneous carriers in the carrier aggregation configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate on a first set of carriers in a first frequency range (FR) and a second set of carriers in a second FR. The UE may detect a radio link control (RLC) discontinuity on at least one of the first set of carriers or the second set of carriers. The UE may identify one or more FRs, of the first FR and the second FR, in which the RLC discontinuity occurred. The UE may transmit an RLC status report based at least in part on the identified one or more FRs. Numerous other aspects are described.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.
