Abstract: Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus selects a serving cell for connection to a network. The apparatus performs a search for a frequency band on a neighbor cell for use in device-to-device communications. The apparatus performs the device-to-device communications using pre-configured resources associated with the frequency band when the search for the frequency band on the neighbor cell fails. The apparatus performs the device-to-device communications using resources associated with the frequency band of the neighbor cell when the search for the frequency band on the neighbor cell is successful.

Abstract: Aspects of the present disclosure provide methods and apparatuses that use various connection reconfiguration signaling schemes to enable fast user equipment reconfiguration in wireless networks. A network can reduce reconfiguration signaling traffic or overhead by reducing the amount of configuration data sent to each user equipment (UE) in a reconfiguration message. In some examples, when a UE first enters a network area, the network may provide the UE with a list of commonly used baseline configurations. Each baseline configuration may be identified by an index and a value tag. Subsequently, the network may transmit a reconfiguration message including, for example, only the index and value tag to indicate the desired configuration.

Abstract: Embodiments described herein relate to systems and methods for scheduling subscriptions in a user equipment (UE) having at least a first receive radio and a second receive radio, including receiving, by the first receive radio, a broadcast activity for a first subscription and receiving, by the second receive radio, a reception activity for a second subscription. A trigger event is detected while the broadcast activity for the first subscription is being received by the first receive radio and the reception activity for the second subscription is being received by the second receive radio. In response to detecting the trigger event, the reception activity for the second subscription is received by the first receive radio and the broadcast activity for the first subscription is received by the second receive radio.

Abstract: Methods, systems, and devices are described for recovery from a connection disruption of a user equipment (UE) operating in a multi-carrier mode. The UE may establish a first connection with a primary cell and a second connection with a secondary cell while operating in the multi-carrier mode. A determination may be made that a disruption in the connection with the primary cell has occurred, and the UE may perform a connection reestablishment procedure to attempt to reestablish communications. The connection reestablishment routine may prioritize the secondary cell ahead of one or more other cells for attempting to reestablish communications. The prioritization may be based at least in part on the establishment of the second connection in the multi-carrier mode.

Abstract: Methods and apparatus for enhanced radio resource control (RRC) reestablishment in a communication system include addressing repeated radio link failures (RLFs). For example, the methods and apparatus include incrementing a counter value associated with a first cell based on a detection of a RLF by a user equipment (UE) in a RRC connected state with the first cell. The methods and apparatus further include determining that the counter value meets or exceeds a first barring threshold value within a cell barring evaluation time duration. Additionally, the methods and apparatus include prohibiting the UE from performing an RRC reestablishment procedure with the first cell for a first barring time duration.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reporting signal quality in overlapping Multimedia Broadcast Single Frequency Networks (MBSFN) areas. A UE may determine a signal quality estimate for each of two or more overlapping MBSFN areas based on Signal to Noise Ratio (SNR) information and Modulation and Coding Scheme (MCS) information for the MBSFN area. The UE may then determine a combined signal quality based on the signal quality estimates of the MBSFN areas.

Abstract: Methods, systems, and devices are described for reducing congestion in a wireless communications system. A second connection failure is detected, and a difference between a timestamp of the second connection failure and a timestamp of a first connection failure is calculated. Upon determining that the difference satisfies a first time threshold, information relating to one or more previous connection failures is cleared. A time period is identified. A number of connection failures from a cell that occur during the time period is identified. A determination is made as to whether the number of connection failures satisfies a threshold. Upon determining that the number of connection failures satisfies the threshold, a future connection request may be withheld for a time period.
