Methods, systems, and devices for wireless communications are described for radio frequency (RF) exposure limit compliance using uplink duty cycling. A user equipment (UE) may transmit a buffer status report (BSR) that indicates an amount of data that is to be transmitted by the UE, where lower priority data reported in the BSR may be throttled in order to reduce an amount of uplink resources associated with the lower priority data and thereby adjust an uplink duty cycle of the UE. The reduced uplink duty cycle may provide for additional transmit power that is available for higher priority data transmissions.

Methods, systems, and devices for wireless communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.

Disclosed are a method and an apparatus by which user equipment controls transmission power of a sidelink signal in a wireless communication system that supports a sidelink, according to various embodiments. Disclosed are a method and an apparatus by which user equipment controls transmission power of a sidelink signal in a wireless communication system that supports a sidelink, wherein the method comprises the steps of: calculating required power for each antenna unit included in a plurality of antenna units to which the sidelink signal is transmitted; determining reference transmission power on the basis of the required power calculated for the plurality of antenna units; and allocating transmission power for the plurality of antenna units on the basis of the reference transmission power.

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.

A user equipment receives a signal indicating a time schedule for intermittent transmission of information from a base station managing a cell. The intermittent transmission of information enables the UE to perform mobility measurements when the cell is in a discontinuous transmission (DTX) mode and the UE is an active terminal not served by the cell. The UE performs, based on the intermittent transmission of information, a mobility measurement when the cell is in the DTX mode and reports the mobility measurement to the base station.

Reduced transmission power time intervals for wireless communications are described. A node may transmit a time interval allocation bitmap indicating a configuration of reduced transmission power time intervals. The configuration of reduced transmission power time intervals may change based on traffic load at the node.

A primary wireless access node wirelessly transmits reference signals at an initial reference signal power level. The primary wireless access node exchanges data with User Equipment (UEs) and exchanges the data with other network elements. The primary wireless access node exchanges signaling with secondary wireless access nodes. The secondary wireless access nodes exchange data between the UEs and the network elements responsive to the signaling. The primary wireless access node determines the amount of the secondary nodes and determines a new reference signal power level based on the amount of the secondary nodes. The primary wireless access node wirelessly transmits subsequent reference signals at the new reference power level.

A method for performing wireless communication by a first apparatus and an apparatus for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink control channel (PSCCH) from a second apparatus; receiving a physical sidelink shared channel (PSSCH) related to the PSCCH from the second apparatus; determining a physical sidelink feedback channel (PSFCH) resource related to the PSSCH, on the basis of a slot and sub-channel related to the PSSCH; and obtaining a channel busy ratio (CBR) value related to PSFCH transmission on the PSFCH resource. The CBR value may be obtained on the basis of (i) a first slot before a first offset from a slot that received the PSSCH related to the PSFCH resource, and (ii) measurement in a time section between the first slot and a second slot before a second offset.

An information processing device (60) includes: an acquisition unit (641) that acquires information regarding each of a plurality of second radio systems that share a radio wave used by a first radio system; a calculation unit (642) that calculates an allocation priority for each of the plurality of second radio systems based on the information acquired by the acquisition unit (641); and an allocation unit (643) that allocates, as an interference amount, a total interference amount allowed by the first radio system to each of the plurality of second radio systems based on the allocation priority calculated by the calculation unit (642).
