Problems solved by technology

If the UE transmits service signals on multiple carriers of carrier aggregation at the same time, the total transmit power may exceed the maximum transmit power. Therefore, in order to meet the limit requirements of the maximum transmit power, how to adjust the transmit power of the service signals on the carrier is Urgent problems

Embodiment Construction

[0069] figure 1 is a schematic diagram of the architecture of the communication system applied in the embodiment of the present application, the communication system includes network equipment and at least one terminal, such as figure 1 As shown, the network equipment is shown as an example of a base station, and three terminals are shown, of which figure 1 The communication system shown is an Internet of Vehicles communication system. Terminal 1 to Terminal 3 are vehicle-mounted terminals. Terminal 1 and Terminal 2 are within the network coverage of the base station, and Terminal 1 and Terminal 2 can communicate with the base station; Terminal 3 is located in the base station. It cannot communicate with the base station outside the coverage area of ​​the network. Terminal 1, terminal 2, and terminal 3 can communicate with other terminals within the signal coverage without forwarding via the base station and other network devices, that is, the terminals can communicate with e...

Abstract

The embodiment of the invention provides a communication method and device. The method comprises the steps of obtaining first transmitting power of each carrier in N carriers; Wherein N is an integergreater than or equal to 1; When the sum of the first transmitting powers of the N carriers is greater than the maximum transmitting power, adjusting the first transmitting powers of M carriers in theN carriers according to the service priority corresponding to the signal transmitted by each carrier in the N carriers so as to reduce the sum of the first transmitting powers of the N carriers; Wherein M is an integer greater than or equal to 1, and N is greater than or equal to M. When the first transmitting power of the carrier wave is adjusted, the service priority corresponding to the signaltransmitted by the carrier wave is referenced; Therefore, the performance requirements of the services with different service priorities can be met, the transmission performance requirements of the services with high service priorities are preferentially guaranteed when the power is adjusted, the services with the high service priorities have more appropriate transmitting power, and therefore thereceiving reliability is higher, the coverage range is larger, and the requirements of the Internet of Vehicles services are met.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method and device. Background technique [0002] The main research scope of the Internet of Vehicles of the LTE system includes: vehicle-to-vehicle (V2V) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-infrastructure network (V2I) communication, which are collectively referred to as V2X. The communication in V2X can be implemented based on either a sidelink (Sidelink) interface or a Uu interface. At present, in order to meet the requirements of vehicle formation communication and higher data transmission rate, carrier aggregation of up to 8 PC5 carriers can be supported, that is, user equipment (User Equipment, UE) can transmit signals on multiple carriers, where PC5 refers to the protocol A reference point for inter-device discovery and inter-device communication between UEs in the architecture. ...
