Abstract
This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.
Claims15
A communication method, wherein the method is used for cell selection, and the method comprises:
- when a power class of a terminal device is a first power class, determining, by the terminal device, a first offset of the first power class and a second offset of the first power class;
- determining, by the terminal device and based on the second offset and a smaller value between (1) a sum of the first offset and a maximum transmit power of the terminal device allowed by a first cell and (2) a maximum radio frequency output power that corresponds to the first power class and that is of the terminal device, a compensation amount of the first power class;
- and
- determining, by the terminal device and based on the second offset and the compensation amount of the first power class, whether to camp on the first cell.
A communication method, wherein the method is used for uplink power control, and the method comprises:
- when a terminal device determines that a power class is a first power class, determining, by the terminal device, a first offset of the first power class;
- determining, by the terminal device and based on a smaller value between (1) a sum of the first offset and a maximum transmit power of the terminal device allowed by a serving cell and (2) a maximum radio frequency output power that corresponds to the first power class and that is of the terminal device, a first terminal transmit power corresponding to the first power class;
- and
- determining, by the terminal device and based on the first terminal transmit power, a terminal uplink transmit power corresponding to the first power class.
A communication method, wherein the method is used for random access, and the method comprises:
- when a power class of a terminal device is a first power class, determining, by the terminal device, a first offset of the first power class;
- determining, by the terminal device and based on a sum of the first offset and an initialized preamble initial target received power or a sum of the first offset and an initialized ramping step, at least one of a preamble initial target received power or a ramping step corresponding to the first power class;
- and
- performing, by the terminal device, random access based on the at least one of the preamble initial target received power or the ramping step corresponding to the first power class.
