Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, signaling that indicates a relative power difference between a first cell and a second cell. The UE may apply the relative power difference in a transmission occasion that includes at least a first uplink transmission on the first cell and a second uplink transmission on the second cell, wherein applying the relative power difference causes the first uplink transmission on the first cell to be transmitted at a lower power level than the second uplink transmission on the second cell. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of carriers within a frequency band for communicating with a base station via either carrier aggregation or dual connectivity. The UE may determine that a first parameter for communications over a first carrier exceeds a threshold with respect to corresponding parameters of other carriers, the first parameter being either a downlink reception parameter or an uplink transmission parameter. The UE may refrain from communicating over the first carrier based at least in part on the first parameter exceeding the threshold.

Facilitating a transmission power dependent resource reservation protocol in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise defining, by a system comprising a memory and a processor, a resource reservation procedure that associates respective amounts of reserved resources available for the mobile device based on a transmission power level of the mobile device. The method also can comprise selecting, by the system, an amount of reserved resources from the respective amounts of reserved resources available based on the transmission power level of the mobile device.

The present disclosure includes systems and methods for configuring a radio base station of a cellular telecommunications network. An exemplary method includes receiving an instantaneous bandwidth (IBW) capability list from a radio unit that is coupled to an antenna and transmitting a control message to the radio unit to configure radio carriers for the radio unit. The control message is based on the IBW capability list. Associated network nodes are also included.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a maximum transmission power for an uplink transmission on a first cell of a first cell group (CG) based on a direction of communications (e.g., uplink, downlink, or flexible) with a separate cell of a second CG during a same duration of the uplink transmission and within a same first frequency range, where the direction of communications is either an actual direction or an assumed direction. The UE may receive an uplink grant scheduling the uplink transmission during a symbol and within the first frequency range, determine the maximum transmission power for the UE based on the direction of communications for the separate cell during the symbol and within the first frequency range, and subsequently transmit the uplink transmission in accordance with the maximum transmission power.

A method includes acquiring a plurality of sample level values of a received current frame signal; determining a current power of the current frame signal based on the plurality of sample level values; determining a current traffic signal ratio of the current frame signal based on the plurality of sample level values; taking the current power as a current pilot power of the current frame signal if it is determined that the current traffic signal ratio is less than or equal to a predetermined ratio; and determining the current pilot power of the current frame signal based on the current power, the current power floating upper limit and the current power floating lower limit if it is determined that the current traffic signal ratio is greater than the predetermined ratio. Thus, the pilot power can be accurately determined for different traffic signal ratios.

A wireless power receiver includes a power pickup configured to receive a wireless power from a wireless power transmitter, and a communicator/controller configured to control the wireless power. The wireless power receiver transmits, to the wireless power transmitter during a configuration phase, a configuration packet including an AI flag related to whether the wireless power receiver supports an authentication function, receives, from the wireless power transmitter during a negotiation phase, a capability packet including an AR flag and a potential power value of the wireless power transmitter, wherein the AR flag is related to whether the wireless power transmitter supports the authentication function, and performs a power transfer phase with the wireless power transmitter. The wireless power receiver transmits, to the wireless power transmitter during the power transfer phase, an authentication request message, and receives, from the wireless power transmitter during the power transfer phase, an authentication response message.
