摘要： Disclosed are a method and a device for transmission or reception of an integrated access backhaul node. An operation method of a first IAB node comprises the steps of: receiving information of a power offset from a second IAB node; deriving a first EPRE of a PDSCH transmitted by the second IAB node on the basis of the power offset; transmitting, to the second IAB node, a first message requesting adjustment of transmission power of the PDSCH; receiving, from the second IAB node, a second message including information on the adjusted transmission power of the PDSCH; and applying the adjusted transmission power to the first EPRE, so as to derive the adjusted EPRE of the PDSCH.

摘要： Provided are a method and device for determining transmission power, a terminal and a storage medium. The method includes measuring a first reference signal and determining a pathloss of the first reference signal; determining an pathloss of the uplink transmission according to a type of the uplink transmission, an association relationship between the uplink transmission and the first reference signal, and the pathloss of the first reference signal; determining an power adjustment amount of the uplink transmission; and determining the transmission power of the uplink transmission according to at least one of the pathloss of the uplink transmission or the power adjustment amount of the uplink transmission. Thus, the problem in the related technology that a traditional calculation method in the LTE field is adopted for calculating the transmission power of uplink transmission in the NR field and leads to an inaccurate calculation result is solved.

摘要： A method of a user equipment for transmitting an uplink signal in a wireless communication system is disclosed. The method comprises receiving configuration information related to a plurality of transmission configuration indication (TCI) states, and transmitting the uplink signal based on a specific TCI state among the plurality of TCI states. The specific TCI state includes at least one of i) a reference RS used for an uplink transmission or ii) a reference RS commonly used for the uplink transmission and a downlink reception. A transmission power of the uplink signal is determined based on the specific TCI state, and the specific TCI state is related to one or more power control parameters for determining the transmission power of the uplink signal.

摘要： Systems, methods, and apparatuses for energy saving in heterogeneous wireless communication networks are provided. The small cell (e.g., pico cell, relay cell, femto cell) may adjust its transmit power based on the requirement of user equipments (UEs) in the cell's coverage. The small cell may detect a UE entering its coverage with or without assistance from the macro cell. An appropriate small cell may be selected to serve the UE based on its traffic load when the UE is located in the coverage of multiple small cells. The small cell may also transmit auxiliary synchronization signals to reduce the association time for the UE.
