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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a robust measurement procedure for neighbor base stations (BSs) that are handoff candidates. In some aspects, a user equipment (UE) may designate a first 5G New Radio (NR) neighbor BS as a handoff candidate for the UE based on a first signal strength measurement. The UE may configure a measurement time interval to perform one or more additional signal strength measurements prior to expiration of a time to trigger (TTT) time period. The UE may determine the measurement time interval based on a duration of the TTT time period configured by a serving BS and a number of additional signal strength measurements. The UE may transmit a measurement report to the serving BS after performing the last signal strength measurement and prior to expiration of the TTT time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a radio resource control (RRC) connection with a base station. The UE may receive, from the base station, parameters associated with a set of frequency bands, the parameters indicating a priority of each frequency band of the set of frequency bands. The UE may then measure, based on the priority, one or more frequencies of at least one frequency band of the set of frequency bands. The UE may then transmit, after a time delay and to the base station, a measurement report including measurements of one or more frequency bands of the set of frequency bands.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing communications with a base station by a processor of a wireless device. In one aspect, a processor of a wireless device may receive from the base station a system information change indication in first system information. The processor may determine from the first system information scheduling information of second system information. The processor may determine a factor that a request for the second system information will collide with a request from another wireless device for the second system information. The processor may send the request for the second system information using the determined factor.

Abstract: In various embodiments, a wireless device processor may determine a threat score for a first cell, determine whether the first cell threat score is below a first threat score threshold, update a good neighbor cell data structure using neighbor cell information from the first cell in response to determining that the first cell threat score is below the first threat score threshold, performing cell reselection to a second cell, determine whether the second cell transmits a system information block message indicating fake neighbor cell information, and increase a threat score for the second cell in response to determining that the second cell provides the SIB message indicating fake neighbor cell information and that a good neighbor cell data structure includes an indication of one or more good neighbor cells that are within the time threshold and the location threshold and doing countermeasures in a response to the determination.

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus, e.g., a base station, maybe configured to obtain UE information of a UE. The apparatus may configure one or more parameters of one or more measurement gaps based on the UE information, and transmit, to the UE, measurement gap information on the one or more measurement gaps. The measurement gap information may include the one or more configured parameters. In another aspect of the disclosure, a UE maybe configured to transmit, to a base station, UE information of the UE. The UE may receive a measurement request from the base station in response to the UE information, where the measurement request includes configuration information for one or more measurement gaps based on the transmitted UE information. The UE may measure one or more reference signals during at least one measurement gap.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive information indicating a potential handoff for another apparatus in communication with the apparatus. The apparatus may adjust, based on the information indicating the potential handoff, a communication parameter or a communication rate associated with the communication before the potential handoff occurs. The apparatus may identify a potential handoff during communication with another apparatus. The apparatus may cause, based on identifying the potential handoff, an adjustment to a communication parameter or a communication rate associated with the communication before the potential handoff occurs.
