  • Publication number: 20220174522
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink transmission from a first cell, where the downlink transmission includes information for performing one or more actions associated with a second cell. The UE may identify a satisfaction of a trigger condition associated with one or more parameters at the UE based on a power level of the UE being less than or equal to a threshold power level, a throughput at the UE being less than or equal to a threshold throughput, or both. The UE may additionally identify at least one bandwidth associated with the second cell based on a previous wireless connection. The UE may compare, the at least one bandwidth associated with the second cell with a threshold bandwidth. The UE may then perform at least one action associated with a procedure based on the comparing.

  • Publication number: 20220167226
    Abstract: Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

  • Publication number: 20220167358
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

  • Publication number: 20220070807
    Abstract: A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

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.

  • Publication number: 20220007300
    Abstract: Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.
