Embodiment Construction

[0035] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] Based on the formula, P total =P subcarrier +10*log 10 (N allocation ), this embodiment provides a power control method in the access phase, the method adjusts the transmission power by adjusting the number of sub-channels in the access phase. figure 1 is a flow chart of a power control method in an access phase according to an embodiment of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0037] Step S102, triggering power control;

[0038] Step S104, adjusting the number of sub-channels to control power.

[0039] Through the above steps, the power is adjusted by adjusting the number of sub-channels. Compared with the method of simply inc...

Abstract

The invention discloses a power control method and device in an access phase. The access phase power control method includes: triggering power control; and adjusting the number of sub-channels to control the power. The present invention solves the problem caused by only adopting the method of increasing the power during access in the prior art, thereby making the power control in the access process more reasonable.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power control method and device in an access phase. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services to a terminal, and the base station communicates with the terminal through uplink and downlink. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] Orthogonal Frequency Division Multiple Access (OFDM) technology has become the mainstream technology of wireless communication physical layer technology due to its ability to effectively combat multipath interference and narrowband interference and high spectrum efficiency. Com...
