A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to determine an RU allocated to the apparatus within a communication bandwidth for OFDMA transmission. The apparatus is configured to transmit a data packet on the allocated RU based on requirements associated with an amount of inter-RU interference to other RUs allocated to other wireless devices. In an aspect, the requirements may include at least one of an error vector magnitude (EVM) requirement or a spectral mask requirement.

A terminal apparatus communicates with a base station apparatus by using a plurality of cells including at least a primary cell and a secondary cell. The terminal apparatus decodes a PDCCH with downlink control information format in which at least a transmission power control command field is included, transmits a PUCCH on the primary cell, and determines transmission power of the PUCCH on the primary cell based on at least a PUCCH power control adjustment parameter. The PUCCH power control adjustment parameter is calculated by accumulating at least a value indicated by the transmission power control command field, and in a case where the terminal apparatus receives a random access response message for the primary cell, the transmission power control circuitry is configured to and/or programmed to reset the PUCCH power control adjustment parameter.

A method implemented on a mobile device that starts by receiving a temperature reading from a sensor included on the mobile device. The temperature reading is compared to a threshold temperature and a power cap is set when the temperature reading is greater than the threshold temperature. The power cap is a maximum transmission power of the mobile device. The method then determines if the mobile device is transmitting a critical message. The power cap is released for a period of time if the power cap is set and the mobile device is determined to be sending a critical message. Other embodiments are also described.

A second device (12) comprises: a transmitter configured to transmit a first signal to a first device (11); a receiver configured to receive a second signal that has been transmitted by the first device (11); a demodulator configured to demodulate a second message from the second signal, the second message including an indication of signal strength of the first signal as measured by the first device (11); a signal strength measuring module configured to measure signal strength of the received second signal; and a calculator configured to use the indication of the measured signal strength included in the second message and the signal strength of the second signal as measured by the second device (12) to calculate a measure of the distance between the first and second devices (11, 12).

Some demonstrative embodiments include devices, systems and/or methods of inter-node communication. For example, a first node may communicate with a second node, e.g., via a backhaul link, one or more messages including a restriction recommendation and/or a restriction setting, for example, a precoding restriction, a Relative Narrowband TX Power indication (RNTP) setting, and/or a Relative Wideband Transmit Power (RWTP) setting.

Examples disclosed herein control radiation exposure for a wireless computing device. In one example, the wireless computing device monitors for instances of upload transmissions from a wireless communications module of the wireless computing device, performs a running average of the instances of upload transmissions over a period of time, and determines whether the running average exceeds a threshold value. If the running average exceeds the threshold value, the wireless computing device adjusts upload transmissions from the wireless communications module to control the radiation exposure for the wireless computing device.
