Problems solved by technology

In-band leakage means that the energy of a signal with higher received power leaks into an adjacent signal with lower received energy in the frequency domain. In-band leakage will affect the normal reception of the UE's signal for uplink communication in the LTE system. Uplink communication between eNBs causes adverse effects

Abstract

Provided are a communication method and device. In the embodiments of the present invention, a first user terminal of device to device (D2D) communication acquires an uplink transmit power parameter; the first user terminal determines a transmit power for the D2D communication according to the uplink transmit power parameter and a downlink path loss; and the first user terminal transmits D2D data according to the transmit power for the D2D communication. Bad effects caused by in-band leakage on uplink communication can be reduced by means of the embodiments of the present invention.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a communication method and equipment. Background technique [0002] In a traditional Long Term Evolution (LTE) communication technology, signaling and data for communication between user equipment (UE) need to be interacted through their respective evolved Node Bs (eNB). [0003] Device to Device (D2D) is a direct communication technology. The communication data between UEs does not need to be forwarded by eNB, and the communication interaction can be directly performed between UEs or with the assistance of the network. [0004] LTE-D2D is the latest LTE-based technology for direct communication between UEs defined by the 3rd Generation Partnership Project (3GPP). The LTE-D2D communication technology is an application of D2D added to the existing LTE system. That is, D2D communication and LTE communication will coexist, such as figure 1 As shown, UE1 can ...
