Methods, systems, and devices for wireless communication are described for a beam-aware handover procedure for multi-beam access systems. A source base station may determine that a handover request is to be sent to a target base station in preparation for handover of a user equipment (UE) from the source base station to the target base station, and transmit the handover request to the target base station with an indication of whether the handover is to be delayed. Alternatively or in addition to, either the target base station or the source base station may generate and transmit a time expiration indicator. The indication of whether the handover is to be delayed or the time expiration indicator may allow either the target base station or the UE to determine whether access parameters for the UE are valid.

Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). According to certain aspects, a UE may be configured to detect, in a first bandwidth part (BWP), a condition triggering a mobility procedure that involves a physical random access channel (PRACH) transmission in a second BWP, determining a timeline for transmitting the PRACH in the second BWP, based on a mobility procedure delay that accounts for BWP switching time for switching from the first BWP to the second BWP, and transmitting the PRACH in the second BWP in accordance with the timeline.

An electronic device and method of operating an electronic device are provided. The method includes receiving a wireless charging request from an external electronic device while wireless communication with the external electronic device is performed through a communication circuit of the electronic device, identifying a second frequency, based on a first frequency being used by the wireless communication circuit for the wireless communication, in response to the wireless charging request, and transmitting wireless power to the external electronic device, based on the identified second frequency through a wireless charging circuit of the electronic device while wireless communication with the external electronic device is performed.

A method of selecting a set of beams to be monitored by a User Equipment (UE) in a telecommunication network comprises the steps of receiving measurement data comprising measurements of qualities of beams observed by said UE, where said beams originate from at least one access node (AN) to the UE and from at least one other AN to the UE; retrieving at least one measurement data from a particular UE that matches the received measurement data, where the historical database comprises historical measurement data comprising measurements of qualities of beams observed by UE's in said telecommunication network over time; selecting a set of beams to be monitored by said UE based on the retrieved measurement data and based on subsequent measurement data of the particular UE over time in the historical database; and transmitting said selected set of beams to be monitored to said UE.

A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Adjusting communication channels used by camera to communicate with a base station are described. In one aspect, characteristics of communication channels can be determined and the operation of the camera can be adjusted to use a communication channel based on a comparison of the characteristics of multiple communication channels.

An antenna system having an antenna array including at least first and second phased array antennas, and a method for field-calibrating the antenna array. Before and after a handover period, communication with respective first and second external satellites or other communication systems is performed using both the first and second antennas. A first beam is formed prior to the handover period. During a first portion of the handover period: a second beam is formed for the communication with the first satellite using the first antenna; the second antenna is deactivated for external communication; and the second antenna is calibrated. During a second portion of the handover period, the second antenna is reactivated for a handed over communication with the second satellite by forming a third beam using the second antenna, while the first antenna maintains its communication with the first satellite via the second beam.
