    Abstract: In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

    IPC: H04L12/26

    Abstract: Methods, systems, and devices are described for assessing the quality of end-to-end connectivity for a wireless communication device. Data generated from at least one of existing traffic and networking operations caused by existing traffic of the wireless communication device may be monitored to obtain information related to connectivity quality. One or more values of one or more metrics may be determined using the obtained information. The quality of end-to-end connectivity for the wireless communication device may be assessed using the value(s) of the metric(s). Based at least in part on a result of the assessment, an action may be performed to improve connectivity quality for the wireless communication.

    Abstract: A method and apparatus provide for configuring WLAN measurements for unlicensed spectrum communications. The method and apparatus include receiving, at a network entity, a UE capability message and a reporting message from a UE, determining whether the UE is capable of communicating over the unlicensed spectrum and supports WLAN measurements based on the UE capability message and the reporting message, and transmitting, to the UE, a measurement configuration message including a measurement configuration identifier in accordance with the determination that the UE is capable of communicating over the unlicensed spectrum and supports WLAN measurements. The method and apparatus further include receiving, at a UE, a measurement configuration message and a measurement purpose message from a network entity, determining a measurement configuration of the UE based on the measurement purpose message, and performing one or more measurements for the one or more WLAN access points.

    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.
