Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines whether a timing offset between a PCC and an SCC possibly exceeds a threshold. In addition, the apparatus switches an amplifier gain utilizing one of a first set of gain states or a second set of gain states based on the determination that the timing offset possibly exceeds the threshold. The first set of gain states includes a first number of gain states, and the second set of gain states includes a second number of gain states less than the first number of gain states.

Abstract: Aspects of the present disclosure provide techniques and apparatus for physical broadcast channel (PBCH) coverage enhancements, for example, for machine type communications (MTC). In aspects, the PBCH coverage enhancements may be applied by non-MTC devices. A method for wireless communications typically performed by a base station (BS) is provided. The method generally includes determining a set of resources for a new physical broadcast channel (PBCH) with enhanced coverage relative to a legacy PBCH and communicating to at least one user equipment (UE) based on the determined set of resources for the new PBCH. In aspects, the new PBCH may be transmitted on a subframe allocated for communicating with MTC devices (MTC subframe).

Abstract: The described aspects include methods and apparatus providing MTC in a wireless network. In an aspect, a narrow bandwidth within a wide system bandwidth is allocated for communicating data related to MTC. MTC control data generated for communicating over one or more MTC control channels for an MTC UE within the narrow bandwidth is transmitted over the one or more MTC control channels. The one or more MTC channels are multiplexed with one or more legacy channels over the wide system bandwidth. Other aspects are provided for transmission mode and content of the MTC control data or other MTC data.

Abstract: A UE may identify a first set of preserved resources of one or more sets of preserved resources. An aircraft-borne device may identify a first set of preserved resources of one or more sets of preserved resources. The first set of preserved resources may be associated with a time domain starting point, a time domain duration, and a frequency domain resource allocation. The UE may transmit, to an aircraft-borne device and the aircraft-borne device may, receive from the UE, over at least part of the first set of preserved resources, a synchronization signal and a first payload message. The first payload message may include a first emergency message and may be transmitted and received via one of a first PUSCH, a first PSSCH, or a PSCCH. The aircraft-borne device may forward, to a base station or another aircraft-borne device, at least the first emergency message.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives, from a network entity, a downlink wideband (DL WB) reference signal (RS) based on a frequency-modulated continuous wave (FMCW) signal; and report, based on the DL WB RS, a radio resource management (RRM) measurement. The RRM measurement may cover one or more sub-bands within one or more widebands of the FMCW signal.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

Abstract: Schemes and mechanisms for timing advance adjustment are provided. In a method for wireless communication, a BS transmits, to a user equipment (UE), a first timing offset configuration associated with a first reconfigurable intelligent surface (RIS) state and a second timing offset configuration associated with a second RIS state. The BS transmits, to the UE, a timing offset indication indicating one of the first timing offset configuration or the second timing offset configuration. The BS receives, from the UE based on the timing offset indication, an uplink (UL) communication.
