A mobile device allows transmission of additional outgoing application data requests in response to occurrence of receipt of data transfer from a remote entity, user input in response to a prompt displayed to the user, and a change in a background status of an application executing on the mobile device. Additional outgoing application data requests are foreground application requests.

A terminal according to one aspect of the present disclosure includes a control section that, when spatial relation information for uplink transmission, of any one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) scheduled by downlink control information (DCI) format 0_1 is not configured, determines a power control parameter for the uplink transmission to determine transmit power for the uplink transmission on the basis of the power control parameter, and a transmitting section that performs the uplink transmission by using the transmit power. According to one aspect of the present disclosure, it is possible to appropriately transmit UL transmission.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for managing uplink power control. For example, the techniques may be used for uplink power control for physical uplink shared channel (PUSCH) transmissions from unmanned aerial vehicles (UAVs).

The present disclosure provides a method and device used in a communication node for wireless communications. A communication node determines that first data is transmitted in a first state, selects a first step-size, and transmits a first signal according to first target power; updates a first counter; when the first counter is not greater than a first threshold, and determines that a second counter is updated, transmits a third signal according to second target power; monitors a second signal in a first time window; the first state comprises RRC_INACTIVE State; the first data comprises a small data packet; the first signal, the second signal and the third signal are used for random access procedure; the first counter is used to count a number of transmission(s) of a preamble sequence; the second counter is used to count a number of time(s) the first step-size is increased.

An electronic device may include, for example: a first battery; at least one second battery; a power management module configured to monitor capacity information of the first battery; and a processor electrically connected to the first battery, the at least one second battery, and the power management module. The processor may be configured to: monitor whether a designated event or a low-power state in which a voltage of the first battery drops below a reference value has occurred, while the electronic device is driven using the first battery; determine that the designated event has occurred or that the first battery corresponds to the low-power state; and parallel-connect the first battery and at least one of the at least one second battery, based on determining that the designated event has occurred, or that the first battery corresponds to the low-power state. Various other embodiments are possible.

A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.

Provided are a random access method and device, which may reduce the latency of a terminal device in a random access process and improve the reliability of a first message (MSG) in the random access process. The method includes that: in response to a terminal device initiating random access to a base station of a target cell and the random access is successful, and the terminal device sends first information to the base station of the target cell, the first information including at least one of an Uplink (UL) Timing Advance (TA) and a parameter related to transmission power for a preamble.

Wireless communication devices, systems, and methods related to handling wake-up behavior for power saving, including during discontinuous reception (DRX) operation are provided. For example, a method of wireless communication can include receiving a default wake-up configuration associated with a discontinuous reception (DRX) operation; monitoring, during a wake-up signal (WUS) occasion, for a WUS; determining whether the WUS was received during the WUS occasion; and performing physical downlink control channel (PDCCH) monitoring based on the default wake-up configuration and whether the WUS was received during the WUS occasion.

Systems and methods are described for reducing processing time of messages that are repeatedly received, with increasing frequency, by a device (e.g., user equipment, base station etc.). For example, the systems and methods would have a base station decrease power, possibly to minimum power-out, per policy, if messages beyond the original are received and the time between those messages is decreasing. The decrease in time between messages indicates a more urgent need for the base station to power down. The systems and methods can be adapted for different types of messages (e.g., power-up, power-down, resource request, bandwidth request, service type, call type origination, quality-of-service request, application type, etc.). Each message type is associated with a policy (pre-determined or adaptive) that indicates the default behavior when the method detects a decrease in time between messages.
