Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with a non-terrestrial network entity using a radio configuration over a service link. The UE may receive an indication of a topology change event that is to occur in association with an inter-satellite link. The UE may communicate, after the topology change event, using at least part of the radio configuration over the service link. Numerous other aspects are described.

Abstract: Many environments or operational conditions create repetitive radio frequency (RF) interference conditions resulting from repetitive mechanical or electrical activity. This activity may create oscillations in the RF conditions between an MTC UE and a serving base station. Aspects of the present invention are directed to improving data efficiency and battery life by optimizing communication based on a detected periodicity of repetitive mechanical or electrical activity at the UE by monitoring the oscillations of at least one RF condition between the MTC UE and the base station, and scheduling communication between the UE and the network during periods associated with favorable radio conditions.

Abstract: Certain aspects of the present disclosure propose methods for protecting channel quality indicator (CQI) modulation symbols in a subframe (e.g., a localized frequency division multiplexing (LFDM) subframe). For some aspects, a timing adjustment method may be utilized to adjust time of a UE with respect to an eNodeB. The timing adjustment method may introduce a positive time offset to be used for reducing time mismatch between the UE and the eNodeB. In another aspect, a buffer may be used at the eNodeB to store symbols received by the eNodeB before removing the cyclic prefix information from the subframe. The eNodeB may use the stored symbols and an artificial time delay to ensure that the CQI information is protected. For some aspects, the CQI modulation symbols may not be located at the beginning of an LFDM symbol.
