USER EQUIPMENT AND POWER ALLOCATION METHOD

摘要

A terminal device and a power allocation method are disclosed, relates to the field of communications network technologies. In embodiments of the present disclosure, at least one uplink channel of a first target subframe numbered i is determined; according to uplink channel information of a second target subframe numbered x, a reserved power that is reserved for a base station or a cell group in which the second target subframe numbered x is located is determined, where the reserved power is determined when uplink channel information of the second target subframe numbered x includes a PRACH or includes only an SRS channel or includes no channel. According to the reserved power, a transmit power of each uplink channel in the at least one uplink channel of the first target subframe numbered i is determined. Solutions provided in the embodiments of the present disclosure are applicable to power allocation.

主权项

1. A terminal device, comprising:
a memory, configured to store information that comprises program instructions; and a processor, coupled to the memory and configured to control execution of the program instructions, to configure the terminal device to:
determine at least one uplink channel of a first target subframe numbered i, wherein i is a subframe number in 0 to 9;determine, according to uplink channel information of a second target subframe numbered x, a reserved power that is reserved for a base station or a cell group in which the second target subframe numbered x is located,
wherein the reserved power is determined when an uplink channel of the second target subframe numbered x comprises a physical random access channel (PRACH) indicated by a physical downlink control channel order (PDCCH) order, wherein a transmission time of the second target subframe numbered x and a transmission time of the first target subframe overlap, a start time of the second target subframe is later than a start time of the first target subframe, the second target subframe is a subframe that belongs to a base station or a cell group different from a base station or a cell group of the first target subframe, and x is a subframe number in range of 0 to 9, orthe reserved power is determined when an uplink channel of the second target subframe numbered x comprises a PRACH determined by using a physical downlink channel of a subframe numbered x-n, wherein n is an integer greater than or equal to 5; anddetermine, according to the reserved power, a transmit power of each uplink channel in the at least one uplink channel of the first target subframe numbered i, wherein a sum of transmit powers of all uplink channels of the first target subframe numbered i and the reserved power is less than or equal to a maximum transmit power of the terminal device.
