application example 1

[0284] The method flowchart of application example 1 of the present invention is as follows image 3 shown, including:

[0285] Step 300, determine the transmission scenario to which the terminal belongs;

[0286] The terminal determines the transmission scenario to which the terminal belongs according to one or more of factors such as transmission capability or mode, number of subcarriers, coverage level, channel type, and information to be sent, among which:

[0287] The transmission capability or mode includes: single-carrier single tone transmission, the carrier bandwidth is the first bandwidth; single-carrier single tone transmission, the carrier bandwidth is the second bandwidth; multi-carrier Multi-tone transmission, the carrier bandwidth is the third bandwidth; multi-carrier Multi- tone transmission, the carrier bandwidth is the fourth bandwidth; wherein, the first bandwidth is different from the second bandwidth, for example: the first bandwidth can be 3.75kHz, the s...

application example 2

[0298] Examples of applications of the invention include:

[0299] First, determine the transmission scenario to which the terminal belongs;

[0300] The terminal determines the transmission scenario to which the terminal belongs according to one or more of factors such as transmission capability or mode, number of subcarriers, coverage level, channel type, and information to be sent, as described in application example 1.

[0301] In this application example, for example, according to its transmission capability or mode configuration information, the terminal determines that it supports multi-carrier multi-tone transmission with a carrier bandwidth of the fourth bandwidth (for example, 15kHz), and determines that its coverage level is coverage level 1 according to the downlink measurement results. And the random access Preamble will be sent by using multi-carrier multi-tone through NB-PRACH, then the terminal can determine the transmission scenario it belongs to according to ...

[0318] Application example 3 of the present invention includes:

[0319] First, determine the transmission scenario to which the terminal belongs;

[0320] The terminal determines the transmission scenario to which the terminal belongs according to one or more of factors such as transmission capability or mode, number of subcarriers, coverage level, channel type, and information to be sent, as described in application example 1.

[0321] In this application example, for example, according to its transmission capability or mode configuration information, the terminal determines that it supports multi-carrier multi-tone transmission with a carrier bandwidth of the fourth bandwidth (for example, 15kHz), and determines that its coverage level is coverage level 1 according to the downlink measurement results. And the uplink control information will be sent through the NB-PUSCH using a single-carrier single tone, then the terminal can determine the transmission scenario it belongs t...

Abstract

The invention relates to a method of realizing uplink power control and a terminal. The method of realizing uplink power control includes the steps: the terminal determines the uplink emission power according to the transmission scene owned by the terminal; and the terminal uses the determined uplink emission power to perform uplink transmission. Therefore, the method of realizing uplink power control can determine the uplink emission power and performs uplink transmission through the terminal, and can realize design of the uplink power control scheme.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, wireless communication technologies, and in particular, relate to a method and terminal for realizing uplink power control. Background technique [0002] Machine Type Communications (MTC, Machine Type Communications), also known as Machine to Machine (M2M, Machine to Machine) communication, is the main application form of the Internet of Things (IoT, Internet of Things), which is rapidly developing at this stage. [0003] In order to meet the coverage requirements in harsh environments (such as indoors, basements, etc.), reduce equipment power consumption and equipment costs, and achieve large-scale deployment of low-complexity, low-rate M2M communication equipment, 3GPP organizations based on 200kHz narrowband (NB, Narrowband) The feasibility study and evaluation of the cellular network IoT system were carried out. [0004] Currently, Release 13 of the Long Term Evolution (LTE, L...
