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.

An electronic device according to various embodiments of the present invention may comprise a transmission module including a first transmission module and a second transmission module, and a processor. The processor may feedback-receive a transmission power of the first transmission module, calculate a difference value between a target transmission power and the transmission power of the first transmission module, determine a state of the first transmission module on the basis of the difference value, and turn off a transmission operation of the first transmission module and activate a transmission operation of the second transmission module in accordance with the determination that the state of the first transmission module is abnormal. Various other embodiments are possible.

A power adjustment method and an electronic device are provided. The method includes: detecting whether first information meets a first preset condition, where the first information includes at least one of the following: a first retransmission rate for uplink data, an actual transmission power for uplink data, or a first maximum transmission rate for uplink data, where the first maximum transmission power is a power threshold for transmitting the uplink data configured by a network device for the electronic device; and in a case that the first information meets the first preset condition, using a preset power control algorithm to adjust the first maximum transmission power to a target transmission power, where the target transmission power is greater than the first maximum transmission power and less than or equal to an inherent maximum transmission power of a radio frequency device of the electronic device.

A message transmission method and a device are used to accelerate a random access procedure. The method includes: receiving, by a terminal device, a repetition quantity of an uplink message from a network device, in response to determining that a reference signal receive power (RSRP) range of the terminal device is within an RSRP range corresponding to a signal coverage enhancement level 0, wherein the uplink message comprises a third message of a sequence of messages comprised in a random access attempt; calculating, by the terminal device, transmit power based on a power control parameter for the repetition quantity; and sending, by the terminal device, the uplink message to the network device based on the calculated transmit power.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a response message associated with a random access message, wherein the response message includes an identifier of the UE; select a format of an uplink channel or an uplink signal for acknowledging successful decoding of the response message; determine a transmit power for hybrid automatic repeat request (HARQ) acknowledgment (ACK) information based at least in part on at least one of: a message type of the response message, a mode of random access associated with the random access message, a power control configuration used by a previous transmission of the random access message, or the format of the uplink channel or the uplink signal; and transmit the HARQ ACK information using a power control procedure based at least in part on the transmit power. Numerous other aspects are provided.

Methods and apparatuses for radio frequency exposure mitigation. A method for a user equipment (UE) to transmit a first channel includes receiving first information for a first downlink reference signal (DL RS) and a set of numbers of repetitions. The method further includes determining a first reference signal received power (RSRP) value for the first DL RS, a first spatial filter corresponding to the first DL RS, a first exposure value for the first spatial filter, and a first number of repetitions from the set of numbers of repetitions based on the first RSRP value and the first exposure value. The method further includes transmitting the first channel with the first number of repetitions using the first spatial filter.

User equipment includes a transmission unit that performs uplink transmissions to a base station apparatus via a plurality of uplink carriers; and a control unit that changes a transmission power value of a random access channel to be transmitted with one or more of the plurality of uplink carriers when priority levels are assigned to the respective uplink transmissions on the plurality of uplink carriers; wherein, when the transmission unit fails to transmit a random access preamble with the transmission power value of the random access channel that is changed by the control unit and the transmission unit retransmits a random access preamble, the control unit changes transmission power control of the random access preamble to be transmitted from normal transmission power control.

Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication that is scheduled to be transmitted by a plurality of physical uplink repetitions in multiple slots on a plurality of beams is subject to a maximum permissible exposure (MPE) condition. The UE may determine a transmission adjustment for the plurality of physical uplink repetitions on the plurality of beams, based at least in part on a determination that the uplink communication is subject to the MPE condition, and transmit the uplink communication based at least in part on the transmission adjustment.
