Embodiments of the present disclosure provide a method for transmitting data, including: sensing, by a first device, a scheduling assignment (SA) of another device; measuring a received power of the other device, and measuring a total received energy of a subframe/subband; determining a received power reference value and a total received energy reference value of the other device according to the SA; selecting resources; and transmitting data using the selected resources. According to the method of the present disclosure, the performance of the method which avoids collision based on SA is improved, and measurement accuracy of the total received energy of the subband is increased. Thus, resource selection/re-selection can be performed better. As such, interferences between devices can be avoided effectively.

Apparatus and methods for providing interference management and load balancing in a wireless network. In one embodiment, the method and apparatus utilize quasi-licensed CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with enhanced SAS (Spectrum Access System) and base station (e.g., CBSD) components to enable creation and management of virtual clusters of bases stations connected to the network, so as to enable inter-cluster interference mitigation, while also supporting load balancing between the base stations using coverage area overlap. In one implementation, the SAS reduces the coverage area (transmit power) of one or more base stations on a cluster edge to mitigate inter-cluster interference, and increases or adjusts the coverage of one or more base stations inside of the cluster to enable load balancing.

Assigning carriers to radio ports communicably coupled to a corresponding plurality of antennae of a radio head, wherein the radio head is split into at least first and second split portions, determining a difference between a first power level available to the first carrier via the first set of radio ports and a second power level available to the second carrier via the second set of radio ports, and changing a split of the radio head such that the difference between the first and second power levels is minimized.

The one or more target downlink power adjustment parameters correspond to the second target BWP. And the downlink power adjustment parameters are configured by the network device for respective BWPs separately.

A wireless system is shared amongst a hierarchal tier of entities. A communication management resource receives notification that a second-tier priority entity has been allocated use of a second wireless spectrum as a replacement to first wireless spectrum. In one embodiment, the first wireless spectrum is revoked from the second-tier priority entity based on use of the first wireless spectrum by a first-tier priority entity (such as incumbent entity). The communication management resource controls a wireless transmit power level of a third-tier priority entity in the hierarchy to provide protected use of the second wireless spectrum by the second-tier priority entity. According to one configuration, the communication management resource controls a power level of wireless communications transmitted by a wireless base station operated by the third-tier priority entity.

The present disclosure provides a method and a device in a node used for wireless communication. A first node receives a first information element, the first information element being used for indicating a first reference power value; and receives a second information set, the second information set comprising a second information element, the second information element being used for indicating a second limit power value; and transmits a first radio signal with a first power value; a target receiver of the first radio signal includes a transmitter of the first information element, the first power value is related to a smaller value between the first reference power value and the second limit power value. Taking into account restrictions resulted from interference when adjusting a transmitting power of a desired signal, the present disclosure can address interferences that may occur in V2X system in unicast or groupcast transmission.
