Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.

Abstract: A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.

Abstract: The described techniques may allow transmitting devices to adjust transmission parameters (e.g., transmit power, modulation and coding scheme (MCS)), until reaching an optimal power and/or MCS. These techniques may allow devices to use power efficiently and reduce inter-device interference in a vehicle-to-everything sidelink system. For example, a transmitting device may begin transmissions to a receiving device with initial transmission parameters, which may be configured using a transmission priority and a channel busy ratio. The transmitting device may lower power and/or increase MCS in each of its subsequent transmissions of the same priority, until the receiving device transmits a feedback message that indicates a low signal quality or a failure to decode a previous transmission. The transmitting device may then increase its transmit power and/or decrease its MCS to an acceptable level for a specified time duration based on receiving the feedback message.
