Patent number: 10568052Abstract: Device-to-device (D2D) cross link power control systems and methods may be disclosed. For example, a device such as a UE or WTRU may determine whether it may have simultaneous transmissions where at least one of the transmissions may include a cross link transmission. The device may further determine whether a total transmit power of the simultaneous transmissions may exceed a maximum transmit power of the device. If the device may have simultaneous transmissions and such transmissions may exceed the maximum transmit power, the device may reallocate power based on a priority or priority setting. The device may further determine a maximum cross link power, a maximum device power, and a cross link transmit power level such that the device may further control the power for transmissions based thereon.Type: GrantFiled: September 22, 2017Date of Patent: February 18, 2020Assignee: InterDigital Patent Holdings, Inc.Inventors: Tao Deng, Gregory S Sternberg, Paul Marinier, Gwenael Poitau, Marian Rudolf
