UPLINK TRANSMISSION POWER DETERMINING METHOD AND USER EQUIPMENT

摘要

Embodiments of the present invention provide an uplink transmission power determining method and a user equipment. A user equipment determines a transmission situation of at least one of: a PUCCH, a PUSCH, and an SRS on another cell except a secondary cell in a subframe corresponding to a preamble to be transmitted on the secondary cell, so that the user equipment can determine an uplink transmission power of the user equipment according to the determined transmission situation, thereby solving a problem that it is not provided in the prior art that how a user equipment determines an uplink transmission power of the user equipment when random access is executed through a secondary cell.

主权项

1. A communication method, comprising:
transmitting, by a user equipment, a preamble random access channel (PRACH) in a secondary cell; and transmitting, by the user equipment, at least one of physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) in a cell rather that the secondary cell; wherein a total transmission power of a transmission power of the PRACH and a transmission power of the at least one of PUCCH and PUSCH does not exceed a maximum allowable power.
