Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Provided are a method by which a first device performs wireless communication, and a device for supporting same. The method can comprise the steps of: transmitting one or more reference signals (RSs) to a second device on the basis of first transmit power; receiving, from the second device, information related to a channel state measured on the basis of the one or more RSs; changing the first transmit power to second transmit power on the basis of the information related to the channel state; and transmitting the one or more RSs to the second device on the basis of the second transmit power.

This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

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).

An operating method of a wireless communication device configured to perform wireless communication with a cell. The method involves identifying, from a downlink signal received from the cell, an electromagnetic field state associated with an antenna of the wireless communication device. A power compensation mode for compensating transmission power of a sounding reference signal is selected based on the identified electromagnetic field state. The transmission power of the sounding reference signal is compensated based on the selected power compensation mode. The sounding reference signal is transmitted with the compensated transmission power through the antenna to the cell.

Embodiments of the present disclosure provide for mechanisms to enable full-power uplink transmission. Other embodiments may be described and claimed.

The present disclosure relates to a 5G generation or pre-5G communication system for supporting a higher data transmission rate beyond a 4G generation communication system such as LTE. According to various embodiments of the present disclosure, a method performed by a UE in a wireless communication system, the method comprising, receiving, from a base station, an RRC message including information on at least one power control set for repetition of a PUCCH transmission based on a single beam configuration, and information on one or more PUCCH resource, receiving, from the base station, a MAC CE indicating ID of the one or more PUCCH resource associated with ID of the at least one power control set; and updating the information on the at least one power control set corresponding to at least one TRP, based on the received MAC CE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a sounding reference signal (SRS) transmission, one or more uplink power control parameters based at least in part on whether the one or more uplink power control parameters are associated with a transmission configuration indicator (TCI) state that is associated with at least one of an uplink control channel or an uplink shared channel. The UE may transmit the SRS transmission based at least in part on the one or more uplink power control parameters. Numerous other aspects are described.

An uplink power control parameter configuration method, a terminal, and a network device are provided. The method includes: receiving a power control parameter set sent by a network device; determining a target parameter configuration index or a target parameter value for a first power control parameter item from the parameter set of the power control parameter item of the power control parameter set; and determining a target transmit power of an uplink channel or an uplink reference signal according to the target parameter configuration index or the target parameter value.

Systems and methods are disclosed herein for determining a power to be used for a set of antenna ports for a physical uplink shared channel transmission. In some embodiments, a User Equipment (UE) comprises processing circuitry configured to derive a power P to be used for uplink power control for a physical uplink shared channel transmission and determine a power to be used for a set of antenna ports based on the power P according to a rule that depends on whether the UE is utilizing codebook based transmission or non-codebook based transmission for the physical uplink shared channel transmission. The set of antenna ports is antenna ports on which the physical uplink shared channel transmission is transmitted with non-zero power.
