Abstract: Methods, systems, and devices for wireless communication are described. A wireless system may support efficient techniques for adding license assisted access (LAA) secondary cells (SCells) to a secondary timing advance group (sTAG). For example, a base station may determine whether to add an LAA SCell to an sTAG based on whether the LAA SCell is a scheduling carrier for a user equipment (UE). That is, the base station may determine whether to add an LAA SCell to an sTAG based on whether a UE scheduled to communicate over the LAA SCell is self-scheduled over the LAA SCell or cross-carrier scheduled over another cell. As such, the wireless system may improve the likelihood that a UE may receive a downlink transmission over an LAA SCell in an sTAG that the UE may use to determine a downlink timing reference for an uplink transmission over the LAA SCell.

Abstract: Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.

Abstract: Aspects of the present disclosure provide techniques and apparatus for user equipment initiated handover. Certain aspects include a method for wireless communications by a user equipment (UE) including determining a first signal metric between the UE and a first base station, while the UE has a connection established with the first base station. The method further includes determining a second signal metric between the UE and a second base station, while the UE does not have a connection established with the second base station. The method further includes determining that the second signal metric is stronger than the first signal metric. The method further includes declaring a radio link failure with the first base station based on determining that the second signal metric is stronger than the first signal metric. The method further includes establishing a connection with the second base station.

Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE) may signal a band-specific measurement gap indication based on the capability of a set of receivers to measure target frequency bands while monitoring a set of component carriers (CCs). The UE may receive a measurement gap configuration for a first component carrier (CC) associated with measuring the target frequency bands accounting for the band-specific measurement gap indication. The UE may then perform a measurement on one or more of the target frequency bands according to the measurement gap configuration while continuing to monitor other configured CCs for downlink messages and transmit uplink control messages during gaps configured for the first CC (e.g., using a different receiver). In some examples the measurement gap configuration message includes configuration options and the UE may select the measurement gap configuration for the first CC from the set of available options.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a measurement configuration on a first cell specifying a measurement gap for measuring cells on other frequencies. The UE may then measure a second cell and determine an offset between the timing of the two cells. If the measured frequency band is synchronized (or nearly synchronized), the length of the measurement gap may be reduced. In some cases, the UE may then make measurements on the second cell using a reduced measurement interval, and the UE may power down certain components during the rest of the measurement gap to conserve power. In other cases, the UE may coordinate with the serving cell to reduce the measurement gap to minimize the interruption caused by the gaps.

Abstract: Methods and apparatuses of wireless communications are provided to dynamically determine capability information such that potential configuration and/or resource conflicts may be mitigated among multiple connections while one or more of on-going connections are not interrupted. A user equipment (UE) establishes one or more connections with a network. The UE allocates, in a first resource allocation, one or more resources of the UE to the one or more connections. The UE dynamically determines an instantaneous UE capability information (IUCI) of the UE in response to a change from the first resource allocation to a second resource allocation, the IUCI indicative of the capability of the UE during a predetermined time period. The UE transmits the IUCI to the network to mitigate potential resource allocation conflict among the one or more connections while maintaining at least one of the connections.

Abstract: Aspects are provided that allow a user equipment (UE) to facilitate interference measurements configuration for assessing impact of network entity backoff adaptation relaxation. The UE may obtain interference measurements of one or more first reference signals including a measurement prior to and after a backoff adaptation associated with a first network entity, and signal strength measurements of a second reference signal received from the first network entity. The UE also may send, to a second network entity of a serving cell, an interference report indicating whether downlink interference originates from the first network entity based at least in part on the interference measurements and the signal strength measurements. After obtaining the report, the second network entity may send, to the first network entity, a feedback signal indicating whether the first network entity is to modify the backoff adaptation based on the downlink interference to the UE.
