Power allocation method of terminal having multiple carriers configured, and terminal using same

Abstract

Provided are a power allocation method of a terminal having multiple carriers configured, and the terminal using same. The method comprises the steps: determining a representative transmission time interval (TTI) of a first carrier; determining a representative TTI of a second carrier; and on the basis of the length of the representative TTI of the first carrier and the length of the representative TTI of the second carrier, allocating first transmit power to the first carrier, and then allocating second transmit power to the second carrier.

Description

technical field [0001] The present disclosure relates to wireless communication, and in particular, to a power allocation method for a terminal configured with multiple carriers and a terminal using the method. Background technique [0002] Recently, interest in D2D (Device-to-Device) technology for direct communication between devices is increasing. In particular, D2D is attracting attention as a communication technology for public safety networks. Public safety networks have higher service requirements (reliability and security) than commercial communication networks, and also require direct signaling or D2D operations between devices, even when they are not covered by the coverage of cellular communications or cannot be used for The same is true for cellular communications. [0003] D2D operation may have various advantages as it sends and receives signals between adjacent devices. For example, D2D user equipment has a high data rate and low latency and can perform dat...

[0007] This kind of operation is a new kind of operation that did not exist before, and therefore, which scheme to use to allocate transmit power for each carrier may become an issue
