Abstract: The present disclosure provides several methods, user equipment (UEs) and base stations for transmitting uplink signals. After receiving uplink synchronization command information, the UE may transmit an uplink signal on at least one idle unlicensed cell. Besides, the UE may try to transmit the uplink signal on multiple uplink signal resources within an uplink signal transmission window. By using the present disclosure, transmission probability of uplink signals may be improved, and time delay of uplink synchronization may be shortened.

Abstract: Embodiments of the present disclosure provide a V2X communication method and apparatus. The method is applicable for a V2X node and includes: detecting a downlink control channel whose CRC code is scrambled by a V-RNTI relevant to the V2X node; and receiving V2X data information on a corresponding downlink data channel according to an indication of the detected downlink control channel. In the present disclosure, the receiving V2X node is able to receive V2X data information selectively, which avoids useless data receiving and data processing operations of the receiving V2X node, reduces the number of downlink control channels and downlink data channels to be detected and processed by the receiving V2X node.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a power allocating method. A User Equipment (UE) receives power control indication information from a control node, obtains a power control mode, and/or, uplink transmission power configuration information. The UE allocates power for each uplink carrier, based on the power control mode, and/or, the uplink transmission power configuration information. By applying the present disclosure, power waste generated in the following scene may be reduced. A scheduled uplink signal cannot be transmitted in a corresponding carrier due to a busy channel. Subsequently, uplink scheduling efficiency of the UE may be improved, and the whole network efficiency may also be enhanced.
