Embodiment 1

[0059] Step 1: The base station determines the terminal that needs to receive the multicast power control command, and transmits the multicast power control command to the terminal on a specific frequency point;

[0060] Step 2: The terminal determines that the frequency point at which the network side transmits the power control command for the multicast of the terminal is a specific frequency point, and receives the power control command for the multicast of the terminal at the determined specific frequency point.

Embodiment 2

[0062] Step 1: The base station determines the terminal that needs to receive the multicast power control command, and transmits the multicast power control command for the terminal on the data transmission frequency of the terminal;

[0063] Step 2: The terminal determines that the frequency at which the network side transmits the power control command of the multicast of the terminal is the data transmission frequency of the terminal, and receives the power control of the multicast of the terminal at the data transmission frequency of the terminal command.

Embodiment 3

[0065] Before transmitting the multicast power control command to the terminal on a specific frequency point according to the set time period, the network side uses high-level signaling to determine the time period and the time position of the multicast power control command within the time period. When the information is sent to the terminal, the time period and the information about the time position at which the multicast power control command is sent within the time period can be included in the TPC-PDCCH-Config information element (IE) as shown below:

[0066]

[0067]

[0068] Among them, rf4 indicates that the period is 4 wireless frames.

Abstract

The embodiment of the invention discloses a power control command transmission method and equipment, which relate to the field of wireless communication and are used to solve the problem of how to transmit multicast power control commands in a small bandwidth system. In the present invention, the network side determines the terminal that needs to receive the multicast power control command, transmits the multicast power control command to the terminal on one or more frequency points, and the terminal determines that the network side transmits the multicast power control command to the terminal The frequency point where the power control command is located, and receive the multicast power control command to the terminal at the determined frequency point. It can be seen that the present invention solves the problem of how to transmit multicast power control commands in a small bandwidth system.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and equipment for transmitting power control commands. Background technique [0002] The Internet of Things technology is in the ascendant, and the third-generation mobile communication system and its long-term evolution system (LongTerm Evolution, LTE) need to support machine type communications (Machine Type Communications, MTC) functions. [0003] Machine-to-machine (M2M, Machine-to-machine) communication is a new type of communication concept whose purpose is to organically combine a variety of different types of communication technologies, such as: machine-to-machine communication, machine control communication, human-machine interactive communication, Mobile Internet communications, thereby promoting the development of social production and lifestyle. It is estimated that the business of human-to-human communication in the future may only account for 1 / 3 of ...
