Abstract: Apparatus, methods, and computer-readable media for facilitating determining or predicting a communication state of a UE based on, for example, measurements performed at the UE are disclosed herein. The communication state of the UE, such as an HST state or a non-HST state, may also be associated with a mobility state, such as stationary or moving. The UE may communicate based on the communication state. An example method for wireless communication at a UE includes establishing a connection with a network node. The example method also includes measuring one or more signals received from the network node over a time period. The example method also includes communicating with the network node based on a communication state of the UE, the communication state of the UE based at least in part on a history of measurements performed on the one or more signals received over the time period.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

Abstract: Aspects are provided which allow a UE to apply CFO compensation to resolve mismatched RAPIDs caused by uplink Doppler shifts in HST deployments. The UE obtains one or more RARs each including a RAPID, where each of the RARs is responsive to a random access message including a preamble. The UE determines, in each of a threshold number of the one or more RARs, that the RAPID of a corresponding RAR is different than the preamble of a corresponding random access message. The UE then offsets a carrier frequency for each of one or more subsequent random access messages in response to the determination. As a result, mismatched RAPIDs due to uplink Doppler shifts may be avoided and RACH success rates may thereby be improved.
